I-beams refer to rolled iron beams or steel beams with I-shaped cross-sections, which are widely used in the field of construction as truss systems or high-rise floor beams, such as main purlins or secondary purlins and other important building components. For building base plates with small spans, such as roof panels and floor deck building systems, I-beams can well withstand the pressure of the building base plate. However, when the span of the building floor increases or the suspension load increases, the pressure on the I-beam also increases, and there will be insufficient stress at the point where the upper surface of the upper flange of the I-beam contacts the building floor.

In view of this problem, the prior art generally adopts a Π-shaped or Ω-shaped fixing seat on the upper or lower part of the building base plate to perform equivalent reinforcement treatment on the building base plate (such as the patent application No. 200720007804.X in Figure 2), or through Components such as welding support frames or gaskets increase the supporting area of the upper surface of the upper flange of the I-beam. Among them, although the method of adding a fixing seat can play a good strengthening effect, due to the installation of the fixing piece, it is necessary to puncture and punch holes in the building floor, and then fix the connection by bolts. This method will cause damage to the building base plate itself, making the puncture of the building base plate easy to be corroded by rainwater or other liquids during use, shortening its service life. Simultaneously, puncture and perforation also can increase working procedure, bring trouble to construction. As for the welding support parts, because the welding process needs to consume energy and there is an open flame, it will bring certain safety risks to the construction.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited by the following detailed description.

The installation support provided in this application is suitable for a building floor with an opening at the bottom, and a building floor for installing a slideway structure for the suspension pendant in the opening. For example, the application number applied by the applicant is: the building floor disclosed in 201610849170.6. And the improved building floor as shown in Figure 1. Fig. 1 is a schematic cross-sectional structure diagram of a building component spliced by two open-shaped building base plates with buckles. As can be seen from Fig. 1, the building floor includes a load-bearing surface, and the two sides of the load-bearing surface are oppositely arranged lap joints, and a strengthening wave crest is arranged between the lap joints, and the lap joints on both sides of the load-bearing surface are facing upwards. Extend and reversely bend downwards to form convex rib I 1 , extend horizontally and then bend upwards to form an extension surface, and the extension surfaces of the two overlapping parts are bent in the same direction again to form a joint surface. The joint surfaces of the overlapping parts on both sides of the load-bearing surface have the same shape, but different sizes. The overlapping parts of the adjacent building floors can be connected by the bending and lapping of the joint surfaces of different sizes. When two adjacent building floors After the lap joints are connected by snap-fit lap joints, a groove 3 that is composed of two ribs I 1 into a chute 2 structure is formed at the connection position. A groove 3 parallel to the rib I1 is provided on both sides of each building bottom plate near the inner side of the rib I1, so as to fix other suspension components.

2 to 6 are structural schematic diagrams of different angles of the support in a preferred solution of the present invention. 2 is a front view, FIG. 3 is a side view, FIG. 4 is a top view, FIG. 5 is a bottom view, and FIG. 6 is a schematic diagram of a three-dimensional structure. As can be seen from FIGS. 2 to 6 , the support is composed of two supporting plates 41 of the same size and specification, a vertical plate 42 with a trapezoidal structure as a whole, and two assembly parts 5 at the bottom of the supporting plates 41 . Ridges II 43 of the same size and specification are provided on both sides of the upper surface of the supporting plate 41 . The support can be made by fixed connection of different parts, and can also be integrally formed by casting. The same two sides of the supporting plates 41 are arranged opposite to each other, and the two supporting plates 41 are connected as a whole by ribs II 43 perpendicular to the corresponding sides on both sides of the upper surface of the supporting plates 41 . At the same time, in the middle of the two ribs II 43 , both ends of the bottom edge of the riser 42 are respectively fixedly connected to the upper surface of the supporting plate 41 . Wherein, the plane where the supporting plate 41 is located is perpendicular to the plane where the riser 42 is located. The supporting plate 41 is provided with a threaded hole 46 penetrating through the round platform of the assembly part 5 and going deep into the supporting plate 41 . Thus, when the assembly part 5 and the supporting plate 41 are stretched, the vertical plate 42 can also bear the force on the supporting plate 41 . In order to reduce the weight of the riser 42 , a hollow structure 421 penetrating through the riser 42 is provided on the riser 42 .

The corresponding sides of the two supporting plates 41 form a limit groove 44 with the bottom of the vertical plate 42 and the bottom of the rib II 43 at the upper part of the corresponding space, and the span of the limiting groove 44, that is, the corresponding two supporting plates 41 The distance between the sides is not less than the width of the upper flange of the I-beam used, so that the upper surface of the I-beam can just be embedded in the limiting groove 44 . As a result, the supporting plates 41 extending from both sides of the upper flange of the I-beam expand the supporting area of the upper flange of the I-beam and form a cross with the I-beam, which is more conducive to supporting the building floor. Simultaneously, the riser 42 that is connected with supporting plate 41 also can share the pressure to I-beam and supporting plate 41.

At the same time, the invention also provides an installation assembly for installing the I-beam by using the support. The mounting assembly at least includes an upper connector and a lower connector. Wherein, FIG. 7 is a front structural schematic view of the upper connector. Fig. 8 is a schematic diagram of the formal structure of the lower connector. It can be seen from FIG. 7 that the upper connecting piece is composed of a support 4, two fixing pieces 6, two fastening bolts 7, and two T-shaped bolts (not shown). Wherein, the support 4 is fixedly connected with the fixing member 6 as a whole through the threaded hole 46 and the fastening bolt 7 . The T-shaped screw fixes the support on the building base plate through the through hole.

The fixtures of the upper connectors are different from those of the lower connectors (Figures 7 and 8). The cross-section of the upper fixing part 61 of the upper connecting part is an inverted trapezoidal structure with no upper side as a whole, and the bottom surface is provided with through holes or threaded holes for passing through the fastening bolts 7 . One side is connected to the L-shaped rounded corner of the bent plate through a connecting cylinder, and the other side is provided with a supporting surface supporting the bottom of the parallel surface on the I-beam 9 . The difference between the lower connecting piece and the upper connecting piece is: on the one hand, the length of the fastening bolt 7 is longer because it needs to support the bottom surface of the lower flange of the I-beam; on the other hand, only one fixing piece 6 is provided, and the fixing piece 6 is the top A channel structure without a bottom is provided on the right side of the through hole. Both ends of the fixing member 6 are connected with two fastening bolts 7 , and the other ends of the two fastening bolts 7 are respectively connected with the threaded holes 46 on the two supporting plates 41 . Thus, the lower fixing member 62 and the two fastening screws 7 form a supporting structure, so as to support the bottom surface of the lower parallel plane of the I-beam. The lower surface of the lower fixing part 62 is provided with holes or grooves for bolt connection, so that the lower fixing part 62 itself serves as a basis for installing other suspension components.

Fig. 9 is an isometric view of the installation assembly in a preferred solution of the present invention (T-shaped screw is omitted). FIG. 10 is a schematic side view of the structure of FIG. 9 . Fig. 11 is a schematic structural view of the lower connector of the installation assembly in a preferred solution of the present invention. It can be seen from FIGS. 9 to 11 that the installation assembly includes 2 lower-layer connectors and 5 upper-layer connectors. This embodiment also includes seven building base plates 8 with openings downward and one I-beam 9 . Wherein, the top of the T-shaped screw 10 is connected with the chute 2 and fixed by the screw cap at the bottom of the through hole of the support 4 . Both sides of the T-shaped screw rod 10 are provided with downward slope-shaped protrusions to prevent the T-shaped bolt 10 from being unable to be tightened when the screw cap is turned. Wherein, the vertical plate 42, the groove 3 of the building floor cooperates with the rib II 43, which can prevent the support 4 from rotating around the fastening bolt during fastening installation, which will affect the installation. At the same time, when the limiting groove 44 bridges the I-beam, the vertical plate 42 connected to the supporting plate 41 can provide sufficient strength of stress. In this structure, the installation process of the suspension hanger is an assembly process, which only needs to be connected through the matching connection between the structural features of each component, without puncture drilling or welding operations, so that the entire installation process is faster. Convenience, higher efficiency, higher safety, and lower energy consumption.
