Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to parking along a road that is spirally continuous in the up-down direction so as to raise and lower the height of one floor by 360 ° turning travel. It is related to the method of constructing a continuous sloping floor type self-propelled multi-storey parking lot with space, especially the steel frame that constitutes the parking lot is vertically divided into several blocks and one block at a place where crane operation is possible The present invention relates to a method of assembling to construct a continuous sloping floor type self-propelled multi-storey car park.

“Prior Art” As automobiles have become widely used in ordinary households, demand for parking lots for parking automobiles has increased. Especially in urban areas, due to lack of land, multi-story parking lots have been adopted. ing.

Conventionally, this type of multi-storey car park has, for example, horizontal parking floors with multiple floors, and the multi-storey car park has a structure in which these floors are connected by rampways, and a continuous sloping floor with a rising slope in the parking lot. There are two types of self-propelled parking lots.

These self-propelled multi-storey parking lots have many middle and low-rise buildings in Japan, and their structures are reinforced concrete structures (RC structures), such as columns, depending on various conditions of individual buildings.
SRC structures, those with beams, etc. are selected and constructed with appropriate structures.

By the way, in the case of constructing such a middle-and-low-rise multi-story parking lot mainly with a steel frame, a flat stacking method based on a stacking work by a tower crane has been conventionally applied. In other words, after constructing a tower crane, first constructing columns for the first floor, then erection beams (large beams), then constructing small beams and finally tightening them, and finally slabs for each floor. The floors are laid and the upper floors are constructed sequentially by repeating this process.

"Problems to be solved by the invention" However, when constructing a tilting floor type self-propelled multi-storey parking lot by such a construction method, the parking lot has an ascending slope not only in the road but also in the parking lot. It is difficult to distinguish the layers because it is attached, and the steel frame is complicated, so the work efficiency is poor, and because it is a one-story stepwise construction, the construction period is prolonged. There was a problem.

Moreover, when building such a parking lot in the city,
There were some problems to be solved in the construction, such as there was no room in the area around the structure and there were restrictions on crane work.

This invention has been proposed in view of the above circumstances, and can improve workability, does not require a cost for construction, and can shorten the construction period. The purpose is to provide a method for constructing a public continuous continuous sloping self-propelled multi-storey parking lot for use in places subject to restrictions.

"Means for Solving the Problems" Therefore, the present invention is directed to a pair of opposed first inclined straight plate-like straight traveling portions having inner and outer road edges formed at substantially equal slopes,
A pair of opposing straight curved second straight advancing portions having unequal gradient inner and outer road edges, and four bent portions having slant curved surfaces that match the gradients of the first and second straight traveling portions. A floor part configured to be screwed in a rectangular shape by and is a method of constructing a continuous inclined floor type self-propelled multi-storey car park provided continuously in a plurality of floors in the vertical direction, the car park being configured. In constructing the steel frame structure, first, the steel frame structure is at least the parking block frame block forming the frame structure of the parking space portion formed inside the first rectilinear section, and the outer side of the first rectilinear section. A straight advancing frame block that forms the frame of the roadway and the parking space portion formed in the above, a pair of inclined rectilinear part frame blocks that form the frame of the second straight advancing part, and four that form the frame of the bending part. Bending skeleton block Divided advance, then, from the parking lot back corner of the bent portion skeleton block toward the parking front in order 1
While constructing the steel frame of the parking lot by constructing the frame blocks one block at a time, while constructing the steel frame, the deck plate is bridged from the one where the frame block construction is completed, and then the surrounding of the pillar steel frame And, after arranging the upper surface of the deck plate respectively, concrete is placed around the pillar steel frame and on the upper surface of the deck plate to form the pillar and the floor slab, respectively.

In the construction method, the parking skeleton block and the rectilinear section frame block are each further divided into a plurality of vertically divided frame blocks, and the divided frame blocks are erected for each block. And, it becomes advantageous when constructing a large-scale parking lot.

[Operation] According to the present invention, the steel frame that constitutes the parking lot is
At least a parking section frame block, a rectilinear part frame block, an inclined rectilinear part frame block, and a bending part frame block are divided, and a steel frame structure that constitutes a parking lot at a place where a crane operation is possible is provided for each frame block. Since the method of erection is used, the steel frames (column steel frames, girders, girders, etc.) that compose each frame block can be easily erected, and the site can be effectively used, shortening the construction period. Can be planned.

In addition, by erection of the deck plates in order from the one where the skeleton blocks have been erected, it is possible to carry out the deck plate erection work and the steel frame erection work in parallel. Can also be improved.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

First, a basic idea for implementing the construction method according to the present invention will be described with reference to FIGS. 1 (a) and 1 (b).

A problem when constructing a continuous sloping self-propelled parking lot in urban areas is that the site area is small and construction is limited, and the construction period is prolonged.

Therefore, in the present invention, when constructing the steel frame that constitutes the parking lot, the steel frame S is arranged in three columns (A) to (C) and a row as shown in FIGS. 1 (a) and (b). A plurality (18 in the drawing) divided into 6 columns (i) to (vi)
Individual) frame blocks (frame blocks divided into wards), and (A) to (i) at the back corner of the parking lot.
We adopted a construction method in which frame blocks are erected one by one toward the front of the parking lot in order from the construction section divided by (See Fig. 1 (b)). At this time, workability for erection work of deck plates, etc. was adopted. Considering it, the feature is that the deck plate is bridged from the one where the erection of the frame block is finished during the construction of the steel frame.

In the present invention, in dividing the steel frame that constitutes the parking lot, considering the structure of the continuous sloping floor type self-propelled multi-storey parking lot, it was divided into 18 work sections described below. That is, this construction section is a skeleton of the parking space portion that constitutes the inner parking section formed inside the first straight-moving portion having a pair of opposed inclined planes having inner and outer road edges formed at substantially equal slopes. , The construction section of the parking block frame blocks 5, 8, 11, and 14, which constitute the frame, and the straight part frame block 4, which constitutes the frame of the traveling path and the parking space part formed outside the first straight part, 6,7,9,10,12,13,15 construction section,
,,,,,, and a section of a pair of inclined rectilinear section frame blocks 2 and 17 which form a pair of opposed rectilinear curved second rectilinear sections having inner and outer road edges formed in an uneven gradient, And a construction section of four bending portion frame blocks 1,3,16,18 forming a bending portion having an inclined curved surface that matches the slopes of the first and second straight-moving portions, There are 18 sections in 6 rows. Further, in the construction work, it is preferable to adopt a method of assembling each frame block in a stepwise manner in consideration of safety against horizontal force such as wind.

Next, a specific example shown in FIGS. 2 to 10 will be described.

2 to 4 are process charts showing the construction procedure of the continuous sloping floor type self-propelled parking lot having the steel frame shown in FIG. 1 (a). First, FIG. 2 (a). As shown in (b) and (b), the foundation A of the parking lot is constructed on the ground G where the parking lot is to be constructed. This foundation A connects a plurality of foundation concrete 20 provided corresponding to the position where a pillar is built, and connects the foundation concrete 20 between these foundation concrete 20 in order to restrain the rotation of these foundation concrete 20. It is mainly composed of an underground beam (connecting beam) 21 that is present. These constructions consist of first constructing foundation piles on the ground G by the earth drill method, then performing root cutting for building footing reinforcements and foundation reinforcements, hitting waste concrete, and then Assembling the formwork of the foundation concrete 20 and the underground girder in the inside, installing the bar arrangement, hitting the concrete and reinforced concrete foundation
It comprises 20 and underground beams 21. After that, when the soil is backfilled to the leveling level, the foundation concrete 20 as shown in FIGS. 2A and 2B and the underground beam 21 made of reinforced concrete are constructed.

After that, as shown in FIGS. 3A and 3B, the bending portion frame block 1 is first erected by proceeding from the work section located at the deep corner of the parking lot. The bending portion frame block 1 is erected by suspending a steel frame column (column made of H-shaped steel) 30 having a plurality of connecting arms 30a for connecting beam members in an upright state and positioned above the basic concrete 20. For this hoisting, it is possible to use a normal-scale truck crane T or the like that enters the site and works. This is because the site is backfilled and leveled at this point, and there is nothing on the leveling level that would hinder the movement of the truck crane T or the like.

Then, the steel columns 30 are hung and fixed to the anchors of the foundation concrete 20, and the six steel columns 30 in the work section are erected by such a procedure.

After the steel columns 30 are erected, a large beam 31 made of H-shaped steel is installed between the steel columns 30 adjacent to each other, as shown in FIG. The steel column 30 and the girder 31 are connected by wrapping the end surface of the connecting arm 30a protruding from the steel column 30 and the end surface of the girder 31 and bolting them together.

Unlike the other frame blocks, the bending part frame blocks 1,3,16,18 are different from those in which the small beam 32 is installed in parallel between the large beams 31 as shown in FIG. The diagonal beam 33 is installed on the diagonal line of the above, and the small beam 32 is installed between the diagonal beam 33 and the large beam 31 located on the outer surface side of the parking lot. Therefore, in the erection of this bending part frame block, the diagonal beam 33 is also erected when the large beam 31 is erected, and after the large beam 31 and the diagonal beam 33 are respectively erected, a small beam is provided between the large beam 31 and the diagonal beam 33. 32 is erected and the bridge of the first layer beam (large beam, diagonal beam, small beam) is completed.

Incidentally, also in bridging the slanted beam 33 and the small beam 32, a means for bolting is applied as in the case of mounting the large beam 31. That is, the diagonal beam 33 is bolted to the steel beam 30 via the connecting arm 30a provided in advance, and the beam 32
Is to be bolted through connecting arms welded to the large beam 31 and the diagonal beam 33, respectively.

By the above procedure, the two-layer beam material (large beam 31, small beam 32,
After the diagonal beam 33) and the brace 34 (see FIG. 7) are attached, the wire 35 for rebuilding is stretched as shown in FIG. 5 (b). In the case of this embodiment, the connecting arm on the second floor
Wires 35 for rebuilding are stretched between the part of 30a and the foundation side of the other pillar 30 constructed next, and the rebuilding of the steel pillar 30 is performed by adjusting the turnbuckle etc. provided for each wire 35. After the predetermined accuracy has been obtained, as shown in FIG. 5C, the rolling tower R is used on the first floor and the suspension scaffold E is hung on the second floor and above to perform the final tightening.

Subsequently, as shown in FIG. 5 (d), the waist wall 40 formed by precasting is attached to the girder 31 located outside the parking lot, and in parallel with it, as shown in FIG. 5 (e). Two
Fry the deck plates D for the third and third floors.

After that, as shown in Fig. 5 (f), erection is performed from the first floor to the upper floor in the same erection order as described above.
The construction of the bending part frame block 1 is completed.

Since the erection order of the skeleton block 1 is basically the same as the erection order of the skeleton blocks in other construction areas, the erection order of each skeleton block will be simplified in the following description.

Through the above procedure, the bending part frame block 1 of the construction section
Once completed, the skeleton blocks after the construction section will be erected for each block. In this embodiment, for example, the time chart shown in FIG. 10 is used.

That is, when the construction of the skeleton block 1 of the construction section is completed, in parallel with the construction of the skeleton block 2 of the construction section, the construction of the skeleton blocks 4 and 7 to be constructed in the construction section is performed for each block. After constructing these frame blocks 4 and 7, in the same way,
, Construction section, and so on, the construction blocks are constructed in parallel for each construction section toward the construction section at the front corner of the parking lot (one construction section at a time).

As shown in FIGS. 4 (a) and 4 (b), during the construction of the steel frame, the deck plate D is erected and the studs 45 are struck in order from the end of the erection of the frame block. In addition, if the column reinforcement 50 and the slab reinforcement (main force reinforcement 51, force reinforcement reinforcement 52) and various piping work are performed in parallel with these operations, it is possible to further improve the work production and contribute to shortening the construction period. Needless to say.

In such a method of constructing a steel frame, it is possible to perform the steel frame erection of other frame blocks, the construction work of the deck plate D, the stud driving work, etc. in parallel, so that the workability is improved. The construction period can be shortened, and since the deck plate is adopted for the floor, there is no need to assemble and disassemble the beam formwork, floor formwork and formwork support work using plywood. . Moreover, since the floor formed by the deck plate D can be used as a scaffold and materials such as reinforcing bars can be placed, effective use of the site even in places where the site is restricted, such as in urban areas. There is also an advantage that can be achieved.

In particular, in this embodiment, the steel frame structure that forms the parking lot is replaced by the four parking block frame blocks 5, 8, 1 that form the frame structure of the parking space formed inside the first straight-movement part.
1,14 and eight straight advancing frame blocks 4,6,7,9,10,12,13,15 that form the framework of the roadway and parking space part formed outside the first rectilinear part, It is divided into two inclined rectilinear section frame blocks 2 and 17 and four bent section frame blocks 1, 3, 16 and 18 which constitute the frame of the second rectilinear section, and these are constructed for each block. Therefore, the skeleton can be simplified and the efficiency of the construction work can be improved.
By constructing each block, there is an advantage that a worker can be skilled in erection of the skeleton and can further contribute to shortening the construction period.

Then, as shown in FIG. 8, from the block where the construction of the steel frame constituting the parking lot is completed, concrete C is cast on the upper surface of the deck plate D to form the slab of the parking lot. Concrete C is wrapped around 30 and around brace 35 to form columns with reinforced steel frame.

Further, in the construction method, the inner parking skeleton frame block and the outer straight part frame block are each further divided into a plurality of frame blocks, and the divided frame blocks are erected for each block. This is advantageous when constructing the large-scale parking lot shown in the figure.

FIG. 9 is a plan view of the first-floor structure of the parking lot constructed as described above, showing a pair of inner and outer road edges formed at equal slopes along the longitudinal direction of the floor. The first rectilinear portions 60 in the form of inclined flat surfaces facing each other are formed, and the pair of inclined curved surface-shaped second portions having inner and outer road edges that are formed at a right angle to these first rectilinear portions are unevenly inclined. Straight portions 61 are provided, and the straight portions 6 are provided at the four corners of the floor.
