Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention and advantageous effects thereof will be described in further detail below with reference to the accompanying drawings.
The adjustable connecting support is used for connecting two solid structures which are arranged at intervals.
Example one
As shown in fig. 1 to 3, the adjustable brace includes: the first screw 30, the second screw 40 and the adjusting sleeve 50 are connected in a threaded manner, specifically, one end of the first screw 30 is fixedly connected with the first structure 10, the other end of the first screw faces the second structure 20, one end of the second screw 40 is fixedly connected with the second structure 20, the other end of the second screw 40 faces the first structure 10, the first screw 30 is provided with a first thread 31, the other end of the second screw 40, namely, one end of the first structure 10 is provided with a second thread 41, one end of the adjusting sleeve 50 is provided with a first threaded hole 51 matched with the first thread 31, and the other end of the adjusting sleeve 50 is provided with a second threaded hole 52 matched with the second thread 41, so that the first screw 30, the adjusting sleeve 50 and the second screw 40 can be connected into a whole through the matching of the threads and the threaded holes, and because one end of the first screw 30 is connected with the first structure 10 and the second screw 40 is connected with the second structure 20, the whole formed by the first screw 30, the adjusting sleeve 50 and the second screw 40 connects the first structure 10 with the second structure 20. The first thread 31 and the second thread 41 have the same rotation direction, and the thread pitches of the first thread 31 and the second thread 41 are different, so that the distance between the first screw 30 and the second screw 40 can be changed by rotating the adjusting sleeve 50, the whole body formed by the first screw 30, the adjusting sleeve 50 and the second screw 40 can extend and retract in the axial direction, and corresponding secondary internal force can be generated for the first structure 10 and the second structure 20, thereby changing the internal force.
Wherein, the pitch of the first thread 31 and the pitch of the second thread 41 are different according to the distance between the first structure 10 and the second structure 20, if the distance between the first structure 10 and the second structure 20 is larger, the pitch of the first thread 31 is integral multiple of the pitch of the second thread 41.
If only the adjustment of the tension and compression state of the structure is realized, the thread pitch of the first threads 31 is approximate to that of the second threads 41, and the difference between the thread pitch of the first threads 31 and the thread pitch of the second threads 41 is only percentage or thousandth.
The tension or compression between the first structure 10 and the second structure 20 is realized by rotating the adjusting sleeve 50 in the forward direction or in the reverse direction, and due to the pitch difference between the two screws, the length condition is changed by the difference, so that the tension and compression of the structures are caused, namely, the stress occurs under the condition that the first structure 10 and the second structure 20 are limited. Since the rotation directions of the first and second threads 31 and 41 are the same, when the adjustment sleeve 50 is rotated, in detail, the adjustment sleeve 50 moves in the same direction simultaneously with respect to the first and second screws 30 and 40, but since the pitches of the first and second threads 31 and 41 are different, the movement distance of the adjustment sleeve 50 with respect to the first screw 30 is different from the movement distance of the adjustment sleeve 50 with respect to the second screw 40, so that the overall length formed by the first screw 30, the adjustment sleeve 50, and the second screw 40 is increased or decreased, and the first and second structures 10 and 20 are compressed or pulled.
For example: if the first thread 31 and the second thread 41 are both left-handed threads and the pitch of the first thread 31 is greater than that of the second thread 41, when the adjusting sleeve 50 rotates in a certain direction to enable the adjusting sleeve 50 to move to one side of the first screw 30, because the pitch of the first thread 31 is greater than that of the second thread 41, the length of the first screw 30 extending into the first threaded hole 51 is greater than the length of the second screw 40 extending out of the second threaded hole 52, so that the total length of the whole formed by the first screw 30, the adjusting sleeve 50 and the second screw 40 is reduced, the first structure 10 and the second structure 20 are pulled to approach each other, and the first structure 10 and the second structure 20 are pulled to be pulled; understandably, if the adjusting sleeve 50 rotates reversely, the adjusting sleeve 50 moves to one side of the second screw 40, and because the pitch of the first thread 31 is greater than that of the second thread 41, the length of the first screw 30 extending out of the first threaded hole 51 is greater than the length of the second screw 40 extending into the second threaded hole 52, so that the total length of the whole formed by the first screw 30, the adjusting sleeve 50 and the second screw 40 is increased, the first structure 10 and the second structure 20 are pushed away from each other, and the first structure 10 and the second structure 20 are pressed.
Understandably, the first and second threads 31, 41 may also be provided as right-hand threads.
Wherein, the first structure 10 and the second structure 20 can be reinforced concrete structures;
or the first structure 10 and the second structure 20 are pure metal structures, the first structure 10 and the second structure 20 may also be solid structures of any other properties, and are not limited herein.
When the first structure 10 and the second structure 20 are reinforced concrete structures, the first screw 30, the adjusting sleeve 50, and the second screw 40 are connected into a whole, then the first structure 10 and the second structure 20 are poured, and at the same time, one end of the first screw 30 and one end of the second screw 40 are respectively inserted into the first structure 10 and the second structure 20, and after the first structure 10 and the second structure 20 are solidified, the fixed connection between the first screw 30 and the first structure 10 and the fixed connection between the second screw 40 and the second structure 20 are realized, so that the first structure 10 and the second structure 20 are integrally connected after the first screw 30, the adjusting sleeve 50, and the second screw 40 are connected, the secondary internal force between the first structure 10 and the second structure 20 can be adjusted, and the distance between the first structure 10 and the second structure 20 and the tension and compression state can be adjusted.
Example two
When the first structure 10 and the second structure 20 are reinforced concrete structures, in the process of pouring the first structure 10 and the second structure 20, the difficulty of pouring is increased by the process of connecting the first screw 30, the adjusting sleeve 50 and the second screw 40 into the first structure 10 and the second structure 20 in a whole and pre-burying the two ends of the first screw and the second screw into the first structure 10 and the second structure 20, which causes inconvenience to pouring construction, so on the basis of the first embodiment, another embodiment of the invention further defines:
as shown in fig. 3 to 6, the adjustable connection brace further includes: first reserved sleeve 60, second reserved sleeve 70, specifically, first reserved sleeve 60 one end is located in first structure 10, the other end is flush with the terminal surface of first structure 10, second reserved sleeve 70 one end is located in second structure 20, the other end is flush with the terminal surface of second structure 20, wherein, first reserved sleeve 60 and second reserved sleeve 70 are coaxially arranged, one end of second screw 40, namely the connection end with second structure 20, is provided with first screw 31, first reserved sleeve 60 is provided with third screw hole 61 matched with first screw 31 of first screw 30, second reserved sleeve 70 is provided with fourth screw hole 71 matched with first screw 31 of second screw 40, so that after connection of first screw 30, second screw 40, adjusting sleeve 50 is completed, the formed whole is assembled to first reserved sleeve 60 and second reserved sleeve 70, so that first reserved screw 30 is detachably connected to first reserved sleeve 60, second screw 40 is detachably connected to second reserved sleeve 70, thereby the connection of second reserved sleeve 10 and second reserved sleeve 20 can be connected to second sleeve 20, the connection of second structure 20 and second sleeve 70 can be more flexibly set up the connection of second sleeve 20, the second sleeve 20 and second structure 20, and the connection of the second structure can be prevented from being damaged by detachable connection of the second reserved sleeve 30, and the second sleeve 70, the connection structure, and the embedded structure 20 can be more flexibly set up.
It should be emphasized that the adjustable connecting brace adopts three sections of the first screw 30, the adjusting sleeve 50 and the second screw 40, and one or more of the three sections can be arbitrarily rotated, on one hand, the adjustable connecting brace is convenient to assemble on the first structure 10 and the second structure 20, and on the other hand, after the assembly is completed, the adjustment of the secondary internal force between the first structure 10 and the second structure 20, the distance between the first structure 10 and the second structure 20 and the tension and compression state can be realized by arbitrarily rotating one or more of the three sections.
Further, adjustable hookup brace still includes: the first fastening nut 32 and the second fastening nut 42, the first fastening nut 32 is used for fastening the first screw 30 and the first reserved sleeve 60, so as to improve the connection stability of the first screw 30 and the first reserved sleeve 60. The second fastening nut 42 is used for fastening the second screw 40 and the second reserved sleeve 70, so as to improve the stability of the connection between the second screw 40 and the second reserved sleeve 70.
Further, as shown in fig. 7, the outer circumferential surface of the first reserved sleeve 60 is provided with a plurality of annular protrusions arranged along the radial direction of the first reserved sleeve 60, and the outer circumferential surface of the second reserved sleeve 70 is provided with a plurality of annular protrusions arranged along the radial direction of the second reserved sleeve 70, so that after the first structure 10 and the second structure 20 are solidified, the concrete structure tightly wraps the outer circumferential surfaces of the first reserved sleeve 60 and the second reserved sleeve 70, and the concrete structure tightly engages with the plurality of annular protrusions to increase the tensile strength between the first reserved sleeve 60 and the concrete structure 70 in the axial direction, thereby preventing the first reserved sleeve 60 from falling out of the first structure 10 or the second reserved sleeve 70 from falling out of the second structure 20 due to an excessive tensile force.
Wherein, the annular bulge can be a hexagonal bulge or a rectangular bulge.
Further, in order to realize that the first screw 30, the second screw 40 and the adjusting sleeve 50 are detachably connected to the first reservation sleeve 60 and the second reservation sleeve 70, the following conditions need to be satisfied:
the minimum distance between the first reserve sleeve 60 and the second reserve sleeve 70 is L1; the sum of the lengths of the first screw 30, the second screw 40 and the adjusting sleeve 50 is L2; if the sum of the lengths of the first threaded hole 51 and the second threaded hole 52 is L3, L2 is greater than L1, and the difference between L2 and L3 is less than L1.
EXAMPLE III
In order to improve the stability of the connection of the first reserve sleeve 60 to the first structure 10 and the stability of the connection of the second reserve sleeve 70 to the second structure 20, further define:
as shown in fig. 8, the adjustable brace further includes: the first embedded part 62 and the second embedded part 72, wherein the first embedded part 62 is connected with the first reserved casing 60; a second embedment 72 is connected to the second pre-sleeve 70, the first embedment 62 being disposed within the first structure 10 and the second embedment 72 being disposed within the second structure 20. Namely, the first embedded part 62 is firstly connected with the first reserved sleeve 60 and embedded into the first structure 10 together with the first reserved sleeve 60, the second embedded part 72 is firstly connected with the second reserved sleeve 70 and embedded into the second structure 20 together with the second reserved sleeve 70, so as to improve the stability of the connection between the first reserved sleeve 60 and the first structure 10 and the stability of the connection between the second reserved sleeve 70 and the second structure 20,
specifically, the first embedded part 62 and the second embedded part 72 are both plate-shaped or rod-shaped, the first embedded part 62 is perpendicular to the axial direction of the first reserved casing pipe 60, and the second embedded part 72 is perpendicular to the axial direction of the second reserved casing pipe 70, so that when the first reserved casing pipe 60 and the second reserved casing pipe 70 are subjected to axial tension, the first embedded part 62 and the second embedded part 72 respectively provide supporting force for the first reserved casing pipe 60 and the second reserved casing pipe 70, and the first reserved casing pipe 60 is prevented from falling out of the first structure 10, or the second reserved casing pipe 70 is prevented from falling out of the second structure 20.
Example four
When the adjustment sleeve 50 is rotated, as the pulling force or the pressing force of the first screw 30 and the second screw 40 increases on the first structure 10 and the second structure 20, the friction force between the adjustment sleeve 50 and the first screw 30 and the second screw 40 increases, and the torsion force applied when the adjustment sleeve 50 is rotated increases, so that the adjustment sleeve 50 is further provided with a fastening portion 53 for assisting the rotation of the adjustment sleeve 50 in order to assist the rotation of the adjustment sleeve 50.
As shown in fig. 9, in one embodiment, the fastening portion 53 is a through hole perpendicular to the axial direction of the adjusting sleeve 50 on the adjusting sleeve 50, and is inserted into the through hole by a tool such as an iron rod, and the adjusting sleeve 50 is rotated by rotating the iron rod, and the iron rod can be used as a labor-saving lever to assist the adjusting sleeve 50 to rotate, thereby facilitating the operation of the operator.
In another embodiment, as shown in fig. 10, the fastening portion 53 provides at least a pair of planes parallel to each other on the outer circumferential surface of the adjustment sleeve 50. So that the plane can be clamped by using a wrench or other tools to assist the rotation of the adjusting sleeve 50, thereby facilitating the operation of an operator.
The invention also discloses an installation method of the adjustable connecting support, which is used for arranging the adjustable connecting support on a first structure and a second structure and comprises the following steps:
specifically, the first screw 30, the second screw 40 and the adjusting sleeve 50 are mounted as follows:
1. the first reserved sleeve 60 and the second reserved sleeve 70 are embedded in the first structure 10 and the second structure 20 respectively.
2. As shown in fig. 3, the three parts are integrated by rotating the first screw 30, the second screw 40 and the adjusting sleeve 50, and a gap is left between the end of the second screw 40 and the bottom of the second threaded hole 52 of the adjusting sleeve 50, and the gap may be 0.01 mm.
3. As shown in fig. 4, the first screw 30, the second screw 40 and the adjusting sleeve 50 are rotated as a whole, so that the first screw 30 is fastened to the first structure 10.
4. As shown in fig. 5, the second screw 40 and the adjusting sleeve 50 are rotated as a whole, so that the second screw 40 is fastened to the second structure 20.
5. As shown in fig. 6, only the adjusting sleeve 50 is rotated to achieve the working state of the first structure 10 and the second structure 20 in tension or compression.
The reason why a gap is left between the end of the second screw 40 and the bottom of the second threaded hole 52 of the adjusting sleeve 50 is to enable the adjusting sleeve 50 to rotate bidirectionally, specifically, after the first screw 30 and the second screw 40 on both sides of the adjusting sleeve 50 are installed, both are in a fixed state, only the adjusting sleeve 50 can rotate at this time, and after one side of the adjusting sleeve 50 is clamped, the bidirectional rotation cannot be achieved, so that a gap needs to be left between the end of the second screw 40 and the bottom of the second threaded hole 52 of the adjusting sleeve 50, wherein a small gap is also left between the outer surface of the second screw 40 and the inner surface of the second threaded hole 52, and the small gap is 0.01 mm.
The invention has the following beneficial effects: when the adjusting sleeve 50 rotates, the distance between the first screw 30 and the second screw 40 can be changed, and a corresponding secondary internal force can be generated for the first structure 10 and the second structure 20, so that the change of the internal force is formed. The invention adopts a three-section structure, well solves the connection between the first structure 10 and the second structure 20, and can adjust the distance and the internal force between the first structure 10 and the second structure 20. The control of the designer on the internal force of the structure is greatly enriched.
In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; the term "plurality" means two or more unless expressly limited otherwise.
