Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a positioning structure for laying floor decking. Background Technology

[0002] Floor decking is a type of metal sheet that serves both load-bearing and formwork functions. It is usually made of profiled steel sheet. In the construction of steel structure or reinforced concrete frame buildings, floor decking needs to be laid, fixed, and connected according to design requirements. The main steps include the transportation and hoisting of floor decking, positioning and laying according to the layout drawing, fixing and connecting it to structural components such as steel beams by welding or bolts, and treating the lap joints between the slabs. In some cases, it is also necessary to tie steel bars on the slabs and pour concrete to finally form a floor load-bearing system. It serves as both a temporary formwork support and a permanent load-bearing component and is widely used in the floor slab construction of industrial plants, high-rise buildings, warehouses, logistics and other buildings.

[0003] During the construction of steel structure floor decking, it needs to be equidistantly overlapped on the steel structure beams on both sides, and then the floor decking is welded to the steel structure beams using studs. Currently, when welding the floor decking and the steel structure using studs, it is mainly done manually by hand holding the welding equipment, inserting the stud into the welding equipment interface, then placing a ceramic ring at the welding position on the floor decking, passing the stud through the ceramic ring and pressing it for welding. After welding, the ceramic rings need to be broken and cleaned one by one, which is a cumbersome operation, and the welding quality of the studs is inconsistent. Summary of the Invention

Detailed Implementation

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the appendix Figure 1-9 This application provides the following technical solutions.

[0031] A positioning structure for laying floor decking includes two central reference blocks 1. Spacing adjustment blocks 3 are movably installed on both sides of each central reference block 1. An electro-permanent magnetic chuck 9 is vertically inserted into the center of each central reference block 1. The upper end of the electro-permanent magnetic chuck 9 contacts the upper surface of the building's steel structure, and a control button is provided at the upper end of the electro-permanent magnetic chuck 9. When the electro-permanent magnetic chuck 9 is energized, it can attract the steel structure beam; then, the power can be turned off. After laying is completed, the electro-permanent magnetic chuck 9 can be energized again to release its attraction from the steel structure beam, allowing the central reference block 1 to be removed. The electro-permanent magnetic chuck 9 uses a common suction strength found in existing technologies.

[0032] Two horizontally symmetrical support plates 2 are provided on both sides of the central reference block 1. The upper and lower ends of the spacing adjustment block 3 are horizontally perforated with sleeve grooves. The spacing adjustment block 3 is horizontally movably fitted with the two support plates 2 via the two sleeve grooves. A first fixing bolt 4 is vertically inserted into the upper center of the spacing adjustment block 3 via a thread. The lower end of the first fixing bolt 4 is inserted into the sleeve groove and abuts against the upper end of the support plate 2. A scale line 26 is provided on the upper end of the support plate 2 near the first fixing bolt 4. The lower ends of the spacing adjustment block 3 away from the central reference block 1 are all provided with... With an L-shaped limiting plate 25, the spacing adjustment block 3 can be adjusted in position via the scale line 26 on the support plate 2. When the center reference block 1 is used alone, first place the center reference block 1 horizontally at the center of the upper end of the steel structure beam where the floor decking needs to be overlapped. Then, adjust the distance between the spacing adjustment block 3 and the center reference block 1 according to the overlap length of the floor decking. Then, when the floor decking is laid, the end of the first block abuts against the side of the L-shaped limiting plate 25 to quickly position the floor decking. Subsequent floor deckings can be aligned with the first block.

[0033] Lightweight metal square tubes 6 are horizontally installed between two spacing adjustment blocks 3 on the same side of the two central reference blocks 1. Each spacing adjustment block 3 has a guide rod 5 on one side. The two sides of the lightweight metal square tube 6 are movably connected to the guide rods 5 on one side of the two central reference blocks 1. A threaded connecting plate 7 is vertically installed on one side inside the lightweight metal square tube 6. A breaking push-pull screw 8 is horizontally rotated at the center of the spacing adjustment block 3 near the threaded connecting plate 7. One side of the breaking push-pull screw 8 is inserted into the lightweight metal square tube 6 and passes through the threaded connecting plate 7 through the thread. When the central reference block 1 and the lightweight metal square tube 6 are used in combination, the two lightweight metal square tubes 6 are horizontally overlapped on the steel structure beam, and then horizontally guided by the two guide rods 5. The movement of the lightweight metal square tube 6 can be controlled by the breaking push-pull screw 8 installed on one side. When the breaking push-pull screw 8 rotates, the threaded connecting plate 7 connected by the thread can drive the lightweight metal square tube 6 to move.

[0034] Several U-shaped mounting brackets 12 are provided on the lightweight metal square tube 6 via a sliding connection assembly. The sliding connection assembly includes a combined slide rail 10 and two connecting sliders 13. The combined slide rail 10 is horizontally provided at the upper end of the lightweight metal square tube 6. Guide grooves 11 are horizontally provided on both sides of the combined slide rail 10. The U-shaped mounting brackets 12 are slidably sleeved on the combined slide rail 10. A second fixing bolt 27 is vertically inserted into the upper center of the U-shaped mounting bracket 12 via a thread. The lower end of the second fixing bolt 27 abuts against the upper end of the combined slide rail 10. The connecting sliders 13 are located on the side of the U-shaped mounting bracket 12 near the guide grooves 11 and are horizontally inserted into the guide grooves 11. Several U-shaped mounting brackets 12 can be provided on the combined slide rail 10. The several U-shaped mounting brackets 12 can be spaced apart from the steel reinforcement frame of the floor deck slab.

[0035] A positioning support assembly is provided to assist in positioning the bottom ceramic ring 17 and the welded stud 18. The positioning support assembly is located on one side of the U-shaped mounting bracket 12 and includes a positioning sleeve 14, a aligning collar 19, and two clamping positioning blocks 21. The bottom ceramic ring 17 is inserted into the lower end of the positioning sleeve 14, and the welded stud 18 is vertically inserted into the bottom ceramic ring 17. One side of each of the two clamping positioning blocks 21 contacts the side of the welded stud 18. One side of the U-shaped mounting bracket 12 contacts the side of the lightweight metal square tube 6. The positioning sleeve 14 is vertically positioned on the side of the U-shaped mounting bracket 12 away from the central reference block 1. The bottom ceramic ring 17 is inserted into the lower end of the positioning sleeve 14, and the inner diameter of the positioning sleeve 14 is equal to the diameter of the bottom ceramic ring 17. A concave annular groove is formed at the lower end of the positioning sleeve 14. 15. A number of crushing cones 16 are symmetrically arranged in the concave annular groove 15. The tips of the crushing cones 16 are in contact with the outer surface of the bottom ceramic ring 17. The lower end of the welding stud 18 is inserted into the inner circumference of the bottom ceramic ring 17, and the upper end of the welding stud 18 passes through the positioning sleeve 14. After the initial laying of the floor deck is completed, the positions of several U-shaped mounting brackets 12 on the combined slide rail 10 are adjusted according to the actual spacing of the floor deck. Similarly, the positioning sleeve 14 will have corresponding positions. At this time, as the two central reference blocks 1 are attracted and fixed to the steel structure beam, the lower ends of several positioning sleeves 14 press down on the positions of the floor deck overlapping the steel structure beam. Then, the bottom ceramic ring 17 and welding stud 18 are inserted from the upper end of the positioning sleeve 14 to fix the positions of the bottom ceramic ring 17 and welding stud 18.

[0036] A aligning collar 19 is installed at the upper end of the positioning sleeve 14. The inner diameter of the aligning collar 19 is equal to the inner diameter of the positioning sleeve 14. Two horizontal expansion grooves 20 are opened on the inner circumference of the aligning collar 19. Two clamping positioning blocks 21 are horizontally inserted into the two expansion grooves 20 respectively. A spring rod 22 is horizontally provided on the side of the clamping positioning block 21 located in the expansion groove 20. The spring rod 22 is movably inserted through the aligning collar 19. A clamping positioning spring 23 is sleeved on the side of the spring rod 22 located in the expansion groove 20. One side of the clamping positioning block 21 extends out of the expansion groove 20 and has an arc-shaped groove. The arc-shaped groove of the clamping positioning block 21 contacts the outer circumference of the weld stud 18. The upper end of the clamping positioning block 21 near the weld stud 18 has a pushing inclined surface 24. Under the elastic support of block 21, the welding studs 18 maintain a vertical posture, ensuring that the welding studs 18 maintain a stable vertical posture when welding the floor deck to the steel structure beam. After the welding is completed, the wrench controls the rotation of the breaking push-pull screw 8, which controls the lightweight metal square tube 6 to move horizontally. At this time, the lightweight metal square tube 6 is connected to the positioning sleeves 14 of several U-shaped mounting brackets 12 to move synchronously. The positioning sleeves 14 squeeze the side of the bottom ceramic ring 17 through several breaking cones 16, so that the bottom ceramic rings 17 under several welding studs 18 are broken at the same time. Then, the combined frame of the central reference block 1 and the lightweight metal square tube 6 is lifted, so that the positioning sleeves 14 are separated from the welding studs 18 and the positioning operation of the next position of paving and welding can be carried out.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
