[0002] Composite slabs are commonly used building components in prefabricated buildings. When in use, composite slabs are supported on the floor to be poured and cast on top of the composite slabs. When using composite slabs, a supporting structure needs to be set at the bottom of the composite slabs.

[0003] Currently, during the installation of composite slabs, the composite slabs are hoisted onto crossbeams and supported at their bottom by multiple sets of support devices. This requires adjusting the level of each set of support devices supporting the composite slab. However, when adjusting the support devices, it is not easy to adjust each set of support devices to the same horizontal height, which will result in unevenness on the bottom surface of the composite slab.

[0004] Therefore, it is necessary to provide a new support device for the construction of truss reinforced concrete composite slabs to solve the above-mentioned technical problems. Utility Model Content

[0007] Preferably, the support structure further includes a spiral tube and a through hole, the through hole being located on the side wall of one end of the I-beam, and the spiral tube being welded and fixed vertically to the inner side wall of one end of the I-beam.

Figure 3 for Figure 2 A schematic diagram of the three-dimensional positioning disk shown; Figure 4 for Figure 3 The diagram shows a top view of the positioning structure. Figure 5 for Figure 1 The diagram shows a cross-sectional view of the I-beam. The support device for the construction of the truss reinforced concrete composite slab includes: a main support rod 1; a positioning structure 2, wherein the main support rod 1 is installed at the bottom end of the positioning structure 2, the positioning structure 2 includes a positioning plate 21, a fixing sleeve 22, a groove 23, a reinforcing plate 24, and a through hole 25, the fixing sleeve 22 is fixed at the center of the bottom surface of the positioning plate 21, the fixing sleeve 22 is installed at the top end of the support rod 1, the groove 23 is located at the edge of the surface of the positioning plate 21, the reinforcing plate 24 is fixed between the side wall of the angle between the fixing sleeve 22 and the positioning plate 21, and the through hole 25 is located on the bottom surface inside the groove 23; a support structure 5, which is fixed to the side wall of the positioning plate 21 by bolts, the support structure 5 includes an I-beam 51, one end of which is engaged inside the groove 23; and a secondary support rod 3, which is supported on the bottom surface of the I-beam 51.

[0022] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the support structure 5 also includes a threaded tube 52 and a through hole 53. The through hole 53 is located on the side wall of one end of the I-beam 51. The threaded tube 52 is vertically welded and fixed to the inner side wall of one end of the I-beam 51. Both sides of one end of the I-beam 51 have through holes 53, and the through holes 53 on the upper and lower sides are aligned. The position of the through hole 53 on the side wall of one end of the I-beam 51 corresponds to the welding position of the threaded tube 52. Furthermore, the position of the through hole 53 on the side wall of one end of the I-beam 51 corresponds to the through hole 2 inside the groove 23. Position 5, and threadedly connected to the threaded tube 52 by bolts through the through hole 25 and the through hole 53; the overall thickness of the I-beam 51 is equal to the depth of the groove 23, and the horizontal surface of the I-beam 51 is flush with the horizontal surface of the positioning plate 21; so that one end of the I-beam 51 can be connected to the positioning plate 21 through the groove 23, and the I-beam 51 and the positioning plate 21 can be fixedly connected together by bolts, and so that all the surfaces of the I-beam 51 and the positioning plate 21 are on the same horizontal plane.

[0023] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, six I-beams 51 are mounted on a positioning plate 21, and three secondary support rods 3 are supported on the bottom surface of each I-beam 51. The composite plate 4 is mounted on the surface of the I-beams 51 and the positioning plate 21. This allows the secondary support rods 3 to strengthen the support of the I-beams 51, enabling the I-beams 51 to more stably support the composite plate 4.

[0024] The working principle of the support device for the construction of truss reinforced concrete composite slabs provided by this utility model is as follows:

[0025] In use, first, the main support rod 1 is fixed vertically in the center of the building. The positioning plate 21 is then installed on the top of the main support rod 1 through the fixing sleeve 22. Multiple I-beams 51 are inserted into the groove 23 through the end with the through hole 53. The position of the I-beams 51 is adjusted so that the through hole 53 is aligned with the through hole 25. Then, the bolt passes through the bottom surface of the positioning plate 21 through the through hole 25 and is threaded to the threaded pipe through the aligned through hole 53. The I-beams 51 are fixed to the positioning plate 21 by the threaded connection of the bolts to the threaded pipe, so that the I-beams 51 are facing outwards. The process is as follows: The composite slab 4 is then hoisted and erected onto the crossbeam, with multiple sets of composite slabs 4 arranged side-by-side. After the composite slabs 4 are erected, the height of the main support rod 1 is adjusted so that it supports the positioning plate 21 against the bottom surface of the composite slab 4 at the center. This causes multiple sets of I-beams 51 fixed to the side walls to simultaneously and horizontally abut against the bottom surface of the composite slabs 4 on the sides. The secondary support rod 3 then supports the I-beams 51, ensuring that each composite slab 4 is supported by I-beams 51 at the same horizontal height. This device has the advantage of easily adjusting each set of support devices to the same horizontal height, ensuring the flatness of the bottom surface of the composite slab 4.

The support structure 5 is then fixed to the positioning structure 2 with bolts. The composite slab 4 is then hoisted onto the crossbeam, with the positioning structure 2 and the support structure 5 positioned directly below the composite slab 4. The support height of the main support rod 1 is adjusted so that the positioning structure 2 and the support structure 5 abut against the bottom surface of the composite slab 4.
