Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete floor decking, and in particular to a prefabricated assembly device for reinforced concrete floor decking that does not require disassembly. Background Technology

[0002] Driven by national policies, prefabricated building structures have experienced rapid development. Traditional cast-in-place concrete floor slabs, which have disadvantages such as long construction periods, large demand for formwork, and high labor costs, are gradually being replaced by prefabricated non-removable floor slabs. Compared with cast-in-place concrete floor slabs, prefabricated non-removable floor slabs have advantages in actual projects, such as shortening the construction period, reducing pollution, and lower maintenance costs.

[0003] Existing prefabricated steel floor deck assembly devices that do not require disassembly typically rely on welding or screws for fixing during the assembly process. This not only increases the complexity and time cost of on-site construction, but may also pose fire hazards and pollute the surrounding environment, affecting the safety and durability of the overall structure.

[0004] Therefore, in view of the existing prefabricated assembly devices for non-removable reinforced concrete floor slabs that typically rely on welding or screws for fixing during the assembly process, which not only increases the complexity and time cost of on-site construction, but also may bring fire hazards and pollution to the surrounding environment, affecting the safety and durability of the overall structure, a prefabricated assembly device for non-removable reinforced concrete floor slabs can be designed to temporarily fix the steel truss through installation plates and fixing plates. Utility Model Content

[0005] In order to overcome the problems that existing prefabricated steel floor decking assembly devices that do not require disassembly usually rely on welding or screw fixing during the assembly process, which not only increases the complexity and time cost of on-site construction, but also may bring fire hazards and pollution to the surrounding environment, affecting the safety and durability of the overall structure.

[0006] The technical solution of this utility model is: a prefabricated assembly device for non-disassembly reinforced concrete floor slabs, including a steel truss; it also includes a fixing block and an installation block. Five fixing blocks are movably connected at equal intervals at the bottom of the steel truss. The fixing blocks have hollow slots inside. A limiting block is fixedly connected to the bottom of the steel truss and is movably connected to the hollow slot. An installation block is movably connected to the top of the fixing block, and an installation plate is fixedly connected to the top of the installation block.

[0007] Preferably, the steel truss is installed on the fixing block through a slot and a limiting block, and then the mounting plate is inserted into the steel truss. The mounting plate is then moved to insert the mounting block on the mounting plate into the fixing block through a tenon and mortise structure. This solves the problem that existing non-removable steel floor deck prefabrication assembly devices usually rely on welding or screw fixing during the assembly process. This not only increases the complexity and time cost of on-site construction, but may also bring fire hazards and pollution to the surrounding environment, affecting the safety and durability of the overall structure.

[0008] Preferably, the bottom of the steel truss is fixedly connected to two rings.

[0009] Preferably, the ring has a connecting rod that is movably connected inside.

[0010] Preferably, a fixing plate is fixedly connected to the bottom of the fixing block.

[0011] Preferably, the top of the fixing plate has multiple circular grooves.

[0012] Preferably, the bottom of the fixing block is provided with six connecting plates, which are fixedly connected to the fixing plate.

[0013] Preferably, the top of the connecting plate has multiple square grooves.

[0014] The beneficial effects of this utility model are:

[0015] By installing the steel truss onto the fixed block through slots and limiting blocks, and then inserting the mounting plate into the steel truss, the mounting plate is moved to insert the mounting block on the mounting plate into the fixed block through a tenon and mortise structure. This solves the problem that existing non-removable prefabricated steel floor deck assembly devices usually rely on welding or screw fixing during the assembly process. This not only increases the complexity and time cost of on-site construction, but also may bring fire hazards and pollution to the surrounding environment, affecting the safety and durability of the overall structure.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a prefabricated assembly device for non-removable reinforced concrete floor decking, comprising a steel truss 1; and also including fixing blocks 5 and mounting blocks 6. Five fixing blocks 5 are movably connected at equal intervals at the bottom of the steel truss 1. A slot 7 is provided inside each fixing block 5. A limiting block 8 is fixedly connected to the bottom of the steel truss 1 and movably connected to the slot 7. An mounting block 6 is movably connected to the top of the fixing blocks 5, and an mounting plate 9 is fixedly connected to the top of the mounting block 6. The steel truss 1 is installed on the fixing block 5 via the slot 7 and the limiting block 8. Then, the mounting plate 9 is inserted into the steel truss 1. The mounting plate 9 is then moved to insert the mounting blocks 6 on the mounting plate 9 into the fixing blocks 5 via a tenon and mortise structure. This solves the problem that existing prefabricated assembly devices for non-removable reinforced concrete floor decking typically rely on welding or screws for fixing during assembly, which not only increases the complexity and time cost of on-site construction but also may pose fire hazards and pollute the surrounding environment, affecting the safety and durability of the overall structure.

[0023] Please see Figures 1-2 In this embodiment, two rings 2 are fixedly connected to the bottom of the steel truss 1. The rings 2 facilitate the disassembly and transportation of the steel truss 1. A connecting rod 3 is movably connected inside the ring 2. The connecting rod 3 is inserted into the ring 2 and fixed to the steel truss 1. A fixing plate 4 is fixedly connected to the bottom of the fixing block 5. The fixing plate 4 fixes multiple fixing blocks 5 in sequence.

[0024] Please see Figures 3-4 In this embodiment, the top of the fixing plate 4 is provided with multiple circular grooves 10. The circular grooves 10 facilitate the increase of contact area and stability during concrete pouring. The bottom of the fixing block 5 is provided with six connecting plates 11. The connecting plates 11 are fixedly connected to the fixing plate 4. The connecting plates 11 fix multiple fixing plates 4 together at a certain distance. The top of the connecting plate 11 is provided with multiple square grooves 12. The square grooves 12 facilitate the increase of contact area and stability during concrete pouring.

[0025] During operation, two connecting rods 3 are inserted into the rings 2 on the steel truss 1 for fixation. The connecting rods 3 have rough outer surfaces to prevent movement after installation. Then, the steel truss 1 is installed on the fixing block 5 through the slots 7 and the limiting blocks 8. Then, the mounting plate 9 is inserted into the steel truss 1. Then, the mounting plate 9 is moved so that the mounting blocks 6 on the mounting plate 9 are inserted into the fixing block 5 through the tenon and mortise structure, thus fixing the steel truss 1 on the fixing plate 4. The round slots 10 and square slots 12 facilitate increasing the contact area during concrete pouring and increase stability.

[0026] Through the above steps, the steel truss 1 is installed on the fixing block 5 through the slot 7 and the limiting block 8. Then, the mounting plate 9 is inserted into the steel truss 1. Then, the mounting plate 9 is moved so that the mounting block 6 on the mounting plate 9 is inserted into the fixing block 5 through the tenon and mortise structure. This solves the problem that the existing non-removable steel floor deck prefabrication assembly device usually relies on welding or screw fixing during the assembly process. This not only increases the complexity and time cost of on-site construction, but also may bring fire hazards and pollution to the surrounding environment, affecting the safety and durability of the overall structure.
