Description
Technical Field
The utility model relates to a construction field especially relates to a structure of preventing falling to wall screw nut is worn to scaffold frame.
Background
The external scaffold is connected with the wall body through a wall-penetrating screw rod: the wall-through screw rod passes through the wall body, the connecting hole on the vertical rod of the scaffold and the base plate and is in threaded connection with the nut. When the scaffold is disassembled, the wall-through screw is screwed out of the inner side of the wall body, meanwhile, workers below the scaffold need to catch the nut and the base plate, the workload is increased, and if the nut and the base plate are not caught, accidents are easily caused.
Among the prior art, in order to solve the problem that nut and backing plate dropped, weld nut and backing plate earlier to with welded nut and backing plate welding on the scaffold frame, the position of nut is unique, can't finely tune the nut. If the nut and the backing plate which are welded together are tied on the scaffold by the steel wire rope, the problem of fine adjustment of the nut is solved, but the following problems exist: when the staff removed the scaffold, nut and backing plate can rock along with the removal of scaffold, easily pound the staff, and in addition, wire rope's fixed is firm inadequately, still has the problem that nut and backing plate fall.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes fasten the fixed mode on the scaffold frame inadequately firm with the nut and the backing plate that wire rope will weld together among the prior art, have the nut and the backing plate easily rock and the shortcoming of the problem of falling, provide a to the scaffold frame structure of preventing falling of threading a wall screw nut.
The utility model discloses the technical scheme who realizes that the purpose adopts is: the utility model provides a structure of preventing falling to scaffold wall screw nut sets up on the montant of scaffold, includes: nut, backing plate and wall screw, nut and backing plate welding, the structure of preventing falling still include: the anti-falling device is wrapped outside the base plate and fixedly connected with the vertical rod of the scaffold, and a hollow nut movement control area is arranged on the anti-falling device.
Furthermore, the anti-falling device is a cover plate covering the surface of the backing plate.
Furthermore, the vertical rods of the scaffold are made of channel steel; the anti-falling device is a pair of check rings arranged in parallel, and a stop position of the base plate moving along the vertical direction is formed at the joint of the check rings and the vertical rod of the scaffold.
Furthermore, the connecting hole between the vertical rod of the scaffold and the wall-through screw rod is a long hole.
Furthermore, the anti-falling device and the vertical rod of the scaffold are fixed by welding.
The utility model has the advantages that: the nut and the backing plate are welded together, the anti-falling device is wrapped outside the backing plate, and when the scaffold is disassembled, the backing plate is limited between the anti-falling device and the vertical rod of the scaffold after the through-wall screw rod and the nut are disconnected, so that the scaffold cannot be separated, and the nut and the backing plate cannot shake and fall.
The present invention will be further described with reference to the accompanying drawings and the detailed description.

In the attached drawing, 1 is a vertical rod, 1-1 is an anti-falling device, 1-1-1 is a nut movement control area, 1-2 is a nut, 1-3 is a base plate, 1-4 is a connecting hole, 2 is a wall body, and 2-1 is a wall-through screw rod.
Detailed Description
As shown in the attached drawings, a structure of preventing falling to scaffold wall screw nut sets up on the montant 1 of scaffold, includes: the wall-penetrating scaffold is characterized by comprising nuts 1-2, backing plates 1-3 and wall-penetrating screws 2-1, the nuts 1-2 are welded with the backing plates 1-3, the wall-penetrating screws 2-1 penetrate through the wall body 2, connecting holes 1-4 in vertical rods 1 of the scaffold and the backing plates 1-3 and are in threaded connection with the nuts 1-2, and the scaffold is fixedly installed outside the wall body 2.
The structure of preventing falling still include: the anti-falling device 1-1 is wrapped outside the backing plate 1-3 and is fixedly connected with the vertical rod 1 of the scaffold. In order to ensure that the safety device 1-1 is more firmly fixed to the vertical rod 1 of the scaffold, the safety device 1-1 is preferably fixed to the vertical rod 1 of the scaffold by welding. The movable position of the backing plate 1-3 is limited between the anti-falling device 1-1 and the vertical rod 1 of the scaffold, and the backing plate 1-3 and the nut 1-2 fixedly welded with the backing plate 1-3 cannot be separated from the vertical rod 1 of the scaffold no matter whether the backing plate is connected with the wall-through screw 2-1 or not, so that accidents caused by the falling of the nut 1-2 and the backing plate 1-3 when the scaffold is disassembled are avoided.
The preferred anti-falling device 1-1 of the embodiment is a cover plate covering the surface of the backing plate 1-3, and the cover plate wraps the backing plate 1-3 from the four sides of the backing plate 1-3 to prevent the backing plate 1-3 from falling.
The vertical rod 1 of the scaffold preferred in the embodiment is made of channel steel; the anti-falling device 1-1 is a pair of check rings arranged in parallel, and a stop position of the backing plate 1-3 moving along the vertical direction is formed at the joint of the check rings and the vertical rod 1 of the scaffold. One side of the check ring is close to the side of the vertical rod 1 of the scaffold, the side of the vertical rod 1 of the scaffold made of channel steel is matched with the check ring, the backing plates 1-3 are limited on the vertical rod 1 of the scaffold from the upper end, the lower end, the left end and the right end of the backing plates 1-3, and the purpose of preventing the nuts 1-2 and the backing plates 1-3 from being separated from the scaffold is achieved.
The anti-falling device 1-1 is provided with a hollow nut movement control area 1-1-1, and the positions of the nut 1-2 and the base plate 1-3 can be moved through the nut movement control area 1-1-1. The backing plate 1-3 moves up and down and left and right in the anti-falling device 1-2, and the purpose of fine adjustment of the installation of the scaffold can be achieved through the fine adjustment nut 1-2 and the backing plate 1-3 when the scaffold is installed.
The preferred scaffold of this embodiment has the connection holes 1-4 between the vertical rod 1 and the wall-through screw 2-1 as long holes. If the distance between the prefabricated holes of the wall-through screw rods 2-1 on the wall body 2 and the distance between the connecting holes 1-4 on the scaffold are different, the connecting holes 1-4 are set to be long holes, the nuts 1-2 and the backing plates 1-3 can move at the vertical positions of the vertical rods 1 of the scaffold, and the installation of the scaffold can be adjusted by combining the long holes and the backing plates.
