Description

Technical Field

[0001] The invention relates to the field of building auxiliary tools, in particular to a scaffolding crossbar quick installation structure. Background Art

[0002] Scaffolding, as an indispensable infrastructure in modern construction, plays a key role in supporting the working platform, ensuring the safety of construction workers and promoting the efficient advancement of various construction processes. It is usually composed of multiple components such as support rods, cross bars and diagonal braces. The stable connection between these components is the cornerstone to ensure the stability and safety of the entire scaffolding system. In traditional scaffolding construction technology, the main way to connect these components relies on the combination of various fasteners and screws. Specifically, the support rod, as the main load-bearing structure of the scaffolding, is tightly connected to the transversely extending cross bars through fasteners to form a stable three-dimensional frame. In order to ensure that the cross bars can fit tightly against the support rods and can withstand loads from different directions, construction workers often need to use multiple screws to pass through the holes reserved in the fasteners to lock the two tightly together. Although this approach has enhanced the firmness of the connection to a certain extent, many problems have arisen during actual operation;

[0003] First of all, screwing the screws multiple times is not only a physically demanding and technically demanding job, but also greatly prolongs the time it takes to build the scaffold. Under the tight schedule pressure, this inefficient connection method has undoubtedly become a major obstacle to improving construction efficiency.

DETAILED DESCRIPTION

[0027] As an embodiment of the present invention, it also includes a first connecting mechanism, which is used to connect the collar 3 and the vertical rod 1. The first connecting mechanism includes connecting plates 8 fixedly connected to the front and rear sides of the two connecting semi-rings 2, respectively. Each connecting plate 8 is provided with a mounting port. Every two matching connecting plates 8 are elastically connected by a first spring 9. The inner walls of the opposite sides of the two connecting semi-rings 2 are fixedly connected with limiting blocks 15. Both sides of the vertical rod 1 are fixedly connected with a plurality of limiting holes 4. Each limiting block 15 is matched with the plurality of limiting holes 4. Every two matching mounting ports are jointly penetrated by a limiting bolt 10, and the two limiting bolts 10 are threadedly connected with limiting nuts 11.

[0028] As an embodiment of the present invention, the two connecting plates 8 on the right side are each provided with a first threaded hole 12, and an adjusting screw 13 is provided through each first threaded hole 12, and each adjusting screw 13 is threadedly connected to the first threaded hole 12, and the left end of each adjusting screw 13 is in contact with the corresponding connecting plate 8;

[0029] As an embodiment of the present invention, it also includes a second connecting mechanism, which is used to connect the transverse rod 7 and the corresponding arc groove 6. The second connecting mechanism includes a connecting column 23 fixedly connected to the bottom of the arc groove 6. The lower end of the transverse rod 7 is provided with a columnar groove 21. The connecting column 23 passes through the columnar groove 21. The inner walls on both sides of the columnar groove 21 are provided with limiting grooves 22. The lower end of the connecting column 23 is symmetrically provided with two strip grooves 24. The inner walls on the opposite sides of the two strip grooves 24 are provided with through openings 27. The two strip grooves 24 are provided with a positionable space. The sliding bars 25 are slidably connected to the inner wall of the corresponding strip groove 24 on the opposite sides of the two sliding bars 25 through the second spring 28. The opposite sides of the two sliding bars 25 are fixedly connected with wedge blocks 26. The inclined surfaces of the two wedge blocks 26 are upward. The other ends of the two wedge blocks 26 pass through the corresponding through openings 27 and extend to the inside of the corresponding limit grooves 22. The lower ends of the two sliding bars 25 pass through the corresponding strip grooves 24. The opposite sides of the lower ends of the two sliding bars 25 are installed with magnetic blocks 30. The adjacent surfaces of the two magnetic blocks 30 are attracted to each other by anisotropy.

[0030] As an embodiment of the present invention, a strip groove 17 is provided on a side wall of each arc groove 6 close to the vertical rod 1, and a guide bar 18 is fixedly connected to one end of each transverse rod 7 close to the vertical rod 1, and each guide bar 18 is penetrated with a vertical opening, and a second threaded hole 20 is provided at the inner bottom of each strip groove 17, and a limiting screw 19 is provided above each guide bar 18, and the lower end of each limiting screw 19 penetrates the corresponding vertical opening and the second threaded hole 20 in sequence, and each limiting screw 19 is threadedly connected to the corresponding second threaded hole 20.

[0031] In the present invention, when in use, the collar 3 is installed first. In the initial state, the limiting bolts 10 and limiting nuts 11 on the two connecting half rings 2 are not connected. At this time, the spacing between the two connecting half rings 2 can be adjusted by rotating the adjusting screw 13, so that the spacing between the two connecting half rings 2 becomes larger. At this time, the collar 3 and the integral shell vertical rod 1 formed by the two connecting half rings 2 move to adjust the position. When it reaches the appropriate position (but it is necessary to ensure that the position has a limiting hole 4), the limiting bolt 10 is rotated in the opposite direction. Under the elastic action of the first spring 9, the two connecting half rings 2 move relative to each other, so that the limiting blocks 15 on the inner sides thereof are stuck in the corresponding limiting holes 4. Then the limiting bolts 10 and limiting nuts 11 on the two connecting half rings 2 are connected, so that the two connecting half rings 2 are limited, and the adjustment of the collar 3 is completed. Similarly, in this way, the collar 3 on the other vertical rod 1 is connected;

[0032] Then, the two ends of the transverse rod 7 are placed into the corresponding arc grooves 6. With the cooperation of the guide strips 18 and the strip grooves 17, the columnar grooves 21 can be just inserted into the connecting column 23. During the insertion operation, the wedge blocks 26 are arranged to move downward, and the two wedge blocks 26 are first pushed to move relative to each other, and the corresponding second springs 28 are compressed (at this time, the two sliding bars 25 drive the two magnetic blocks 30 to move a small amplitude, so they will not be attracted together). When the upper end surface of the connecting column 23 contacts the inner top of the columnar groove 21, the two wedge blocks 26 just correspond to the two limiting grooves 22. Under the elastic action of the second springs 28, the two sliding bars 25 drive the corresponding wedge blocks 26 to be inserted into the corresponding limiting grooves 22 to complete the limiting operation.

[0033] If the transverse rod 7 needs to be disassembled later, the two sliding bars 25 are pinched to move relative to each other so that the two magnetic blocks 30 are in contact. Although the second spring 28 is in a compressed state, the magnetic attraction force of the two magnetic blocks 30 can overcome the elastic force of the second spring 28, ensuring that the two wedge blocks 26 will leave the corresponding limit grooves 22, thereby facilitating the disassembly work.
