Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building structures, in particular to an assembled non-disassembly steel bar truss floor deck. Background Art
[0002] When pouring the floor decking, it is generally necessary to build a steel truss on site, support the steel truss by setting a template under the steel truss, and then support the template with a scaffolding. After the pouring is completed, the template is removed. However, the workload of making the steel truss floor decking on site is relatively heavy, which greatly affects the construction progress. In addition, the existing steel truss floor decking is easy to move during assembly, resulting in offset. In addition, the existing steel truss floor decking is fixed by welding and screws, which may cause the floor decking to loosen and fall over time. For this reason, we propose an assembled non-disassembly steel truss floor decking. Utility Model Content

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0020] Reference Figure 1-4 A prefabricated non-disassembly steel bar truss floor deck comprises a floor deck body 1, a left connecting plate 6 is fixedly installed on one side of the floor deck body 1, a left connecting ring groove 8 is fixedly opened on the side of the left connecting plate 6 away from the floor deck body 1, the left connecting ring groove 8 is three-quarter circular, and the opening faces the upper left corner, a right connecting plate 7 is fixedly installed on the other side of the floor deck body 1, a right connecting ring groove 9 is fixedly opened on the side of the right connecting plate 7 away from the floor deck body 1, the right connecting ring groove 9 is three-quarter circular, and the opening faces the lower right corner The circular diameters of the left connecting ring groove 8 and the right connecting ring groove 9 are consistent, the left connecting plate 6 and the right connecting plate 7 are both fixedly provided with a first fixing hole 10, the left connecting ring groove 8 and the right connecting ring groove 9 are movably provided with a connecting buckle 11, and second fixing holes 12 are fixedly provided on both sides of the connecting buckle 11, and the opening diameters of the first fixing hole 10 and the second fixing hole 12 are consistent; wherein, when the connecting buckle 11 is fully engaged in the left connecting ring groove 8 and the right connecting ring groove 9, the first fixing hole 10 and the second fixing hole 12 are located on the same vertical line.
[0021] The staff lays the floor decking body 1, and then uses the connecting buckle 11, the left connecting plate 6 and the right connecting plate 7 to realize the fixed connection of multiple floor decking bodies 1. The connecting buckle 11 is set to an inverted "S" shape, which can make the connection between the floor decking bodies 1 tighter to prevent gaps from being generated during splicing, resulting in leakage of the device. The first fixing hole 10 and the second fixing hole 12 located on the same vertical line can facilitate the staff to further fix the floor decking body 1.
[0022] As an optional embodiment, a plurality of insertion grooves 3 are symmetrically opened on both sides of the floor deck main body 1 perpendicular to the left connecting plate 6, and a plurality of groups of symmetrical keel grooves 2 are fixedly opened on the upper end of the floor deck main body 1. The keel grooves 2 and the insertion grooves 3 are staggered. A plurality of groups of symmetrical steel trusses 5 are movably installed on the upper end of the keel grooves 2. Insertion ridges 4 are welded and fixed to the lower ends of the steel trusses 5. The sizes of the insertion ridges 4 match the insertion grooves 3 one by one.
[0023] The staff can quickly install the steel bar truss 5 by inserting the grooves 3 and the convex strips 4, thereby improving the convenience of the installation.
[0024] As an optional embodiment, a fixing block 13 is movably engaged in the first fixing hole 10, a groove body 14 is fixedly provided at the lower end of the fixing block 13, a return spring 16 is fixedly provided in the groove body 14, and sliding members 15 are fixedly provided at both ends of the return spring 16; wherein, when the return spring 16 is in an unstressed state, the length of the return spring 16 is greater than the depth of the groove body 14, and the size is consistent with the shape of the first fixing hole 10.
[0025] When the staff drives the fixing block 13 into the left connecting plate 6 and the right connecting plate 7 through the first fixing hole 10, the sliding member 15 slides downward, and the return spring 16 is squeezed and contracted. When the sliding member 15 slides to a certain position, the squeezing of the return spring 16 disappears and returns to its original state. The fixing block 13, the sliding member 15 and the return spring 16 then fix the connecting buckle 11 in the left connecting ring groove 8 and the right connecting ring groove 9.
[0026] As an optional implementation, the connecting buckle 11 is in an inverted "S" shape and is made of a rigid material.
[0027] The connection buckle 11 made of a rigid material can prevent the device from deforming during the connection process, which would cause gaps between the multiple floor decking bodies 1 and thus cause leakage.
[0028] When the utility model is in use, the staff places a plurality of floor decking plate main bodies 1, and then fixes the steel bar truss 5 on the floor decking plate main body 1 through the insertion groove 3 and the insertion convex strip 4, and then fixes the floor decking plate main body 1 through the left connecting ring groove 8 and the right connecting ring groove 9 fixedly arranged on the left connecting plate 6 and the right connecting plate 7, and uses the connecting buckle 11 to fix and connect the floor decking plate main body 1, and then drives the fixing block 13 into the first fixing hole 10, and the sliding member 15 slides downward, and the return spring 16 is squeezed and contracted. When the sliding member 15 slides to a certain position, the extrusion of the return spring 16 disappears and the original state is restored. The fixing block 13, the sliding member 15 and the return spring 16 fix the connecting buckle 11 in the left connecting ring groove 8 and the right connecting ring groove 9, thereby realizing the fixation of a plurality of floor decking plate main bodies 1.
