Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to an assembled non-disassembly-required steel bar truss floor deck. Background Art

[0002] In the construction industry, floor decking is a key component that supports concrete pouring and bears construction loads. Its design and construction quality are crucial to the construction efficiency and structural safety of the building. However, the current floor decking technology faces some challenges in actual construction, which reduce construction efficiency and may affect the safety of the structure.

[0003] Firstly, in the traditional floor slab pouring process, construction units usually use removable floor decking as support, or steel floor decking. The former requires a large number of support frames, and the installation and removal process is time-consuming and labor-intensive. Although the latter reduces the installation time, it is prone to rust during long-term use, which not only affects the appearance of the floor slab, but may also reduce its bearing capacity, thereby affecting the final quality of the floor slab.

[0004] Secondly, the connection method between existing floor deckings is usually relatively simple, mainly relying on aligning and laying the floor deckings. Although this connection method is easy to operate, it may lead to unstable connections in actual construction. When the floor slab is under load, the loosely connected floor decking may cause relative displacement, affecting the stress performance of the entire floor slab. In addition, the simple connection method may cause the floor decking to warp or shift during the construction process. These problems will have an adverse effect on the construction quality and performance of the floor slab.

[0005] In addition, there are certain difficulties in the positioning and fixing of floor slab steel bars in the prior art. In the traditional construction process, the placement and fixing of steel bars usually rely on manual operation, which is not only inefficient but also prone to errors. Since the position of the steel bars is directly related to the bearing capacity and stability of the floor slab, any positioning deviation may pose a potential risk to the safety of the building. In addition, since the fixing of the steel bars is not firm enough, the steel bars may shift during the concrete pouring process, affecting the final quality of the floor slab. Utility Model Content

[0034] A reinforcing rib 14 is provided on the supporting rib 11 , and a plurality of supporting ribs 11 are connected by the reinforcing rib 14 .

[0035] In this embodiment, when the device is needed, first, the snap-fit ​​block 13 provided on one side of the second floor decking plate 2 is snapped into the snap-fit ​​groove 12 provided on one side of the first floor decking plate 1, and then the reinforcing ribs 14 are used to connect the plurality of supporting ribs 11 together to strengthen the structural strength, and then the supporting ribs 11 are correspondingly installed on one side of the first floor decking plate 1 and the second floor decking plate 2, and then the plug-in block 5 is correspondingly placed in the groove provided on the side wall of the plug-in sleeve 8, and then the plug-in sleeve 8 is inserted into the groove provided on the first floor decking plate 1 and the second floor decking plate 2, and then the end of the plug-in rod 7 connected with the tapered block 4 is directly inserted into the plug-in sleeve 8, and then the plug-in rod 7 is inserted into the plug-in sleeve 8.

[0036] See also Figure 1-4 As an implementation method of an assembled non-disassembly steel truss floor decking plate for the positioning device: the positioning device includes a clamping sleeve 15, a clamping rod 16 and a connecting block 17, the connecting block 17 is arranged at the bottom end of the supporting rib 11, the clamping sleeve 15 is fixedly connected to the bottom end of the connecting block 17, and the clamping rod 16 is arranged at corresponding positions in the first floor decking plate 1 and the second floor decking plate 2.

[0037] A clamping rod 18 is disposed in the clamping sleeve 15 , and a clamping slot 19 is formed on a side wall of the clamping rod 16 . One end of the clamping rod 18 is clamped into the clamping slot 19 .

[0038] A push spring 20 is arranged inside the clamping sleeve 15 , and the push spring 20 can be movably sleeved on the outside of the clamping rod 18 .

Due to the special structural design of the guide block 21, when the clamping sleeve 15 is inserted downward, the clamping rod 18 will be gradually retracted into the side wall of the clamping sleeve 15 due to the extrusion of the guide block 21, and at the same time, the clamping rod 18 will compress the push spring 20 set on the outside. When the snap-in sleeve 15 is fully inserted into the corresponding groove, the position of the snap-in rod 18 is aligned with the snap-in groove 19 opened on the outside of the snap-in rod 16, and then the push spring 20 automatically resets and pushes the snap-in rod 18 to engage in the snap-in groove 19, thereby realizing a stable connection between the floor decking and the supporting rib 11. When all the floor decking are laid, the whole is poured, and the poured cement can enter the snap-in sleeve 15 and the plug-in sleeve 8 through the pouring hole 22, thereby preventing the occurrence of hollowing in the snap-in sleeve 15 and the plug-in sleeve 8.

[0042] In summary, when the overall device is in use or running: first, the snap-fit ​​block 13 provided on one side of the second floor decking plate 2 is snapped into the snap-fit ​​groove 12 provided on one side of the first floor decking plate 1, and then the reinforcing ribs 14 are used to connect the multiple supporting ribs 11 together to strengthen the structural strength, and then the supporting ribs 11 are correspondingly installed on one side of the first floor decking plate 1 and the second floor decking plate 2, and then the plug-in block 5 is correspondingly placed in the groove provided on the side wall of the plug-in sleeve 8, and then the plug-in sleeve 8 is inserted into the groove provided on the first floor decking plate 1 and the second floor decking plate 2, and then the end of the plug-in rod 7 connected with the tapered block 4 is directly inserted into the plug-in sleeve 8, and then the plug-in rod 7 is inserted into the plug-in sleeve 8. During the process, the side wall of the plug-in rod 7 will squeeze the elastic plate 10 provided on the inner side of the plug-in sleeve 8, causing the elastic plate 10 to be close to the inner wall of the plug-in sleeve 8. Due to the special structural design of the conical block 4, during the insertion of the plug-in rod 7, the conical block 4 will guide and limit the inclined block 3, so that the inclined block 3 drives the plug-in block 5 to move outward. When the plug-in rod 7 is fully inserted into the plug-in sleeve 8, one end of the plug-in block 5 passes through the groove opened on the side wall of the plug-in sleeve 8 and is inserted into the plug-in groove 6, thereby realizing a stable connection between the first floor deck 1 and the second floor deck 2, and there is no need to dismantle them in the later stage, and they can be directly cast as an integrated whole.

[0043] When the support rib 11 needs to be installed, the clamping sleeve 15 provided at the bottom end of the connecting block 17 is aligned with the corresponding clamping rod 16, and then the clamping sleeve 15 is directly inserted into the corresponding groove of the first floor deck 1 or the second floor deck 2.

At the same time, the clamping rod 18 will compress the push spring 20 set on the outside. After the sleeve 15 is fully inserted into the corresponding groove, the position of the clamping rod 18 is aligned with the clamping groove 19 opened on the outside of the clamping rod 16, and then the push spring 20 automatically resets and pushes the clamping rod 18 to engage in the clamping groove 19, thereby realizing a stable connection between the floor decking and the supporting rib 11. When all the floor decking are laid, the whole is poured, and the poured cement can enter the clamping sleeve 15 and the plug-in sleeve 8 through the pouring hole 22, thereby preventing the occurrence of hollowing in the clamping sleeve 15 and the plug-in sleeve 8.
