Description

Overhanging scaffolding pole with anti-skid device

technical field

The utility model relates to the field of scaffolds mainly supported on the ground, in particular to an overhanging scaffold pole with an anti-skid device.

Background technique

With the vigorous development of my country's housing construction industry and the increasing requirements of the government and enterprises for safe and civilized construction, housing construction generally requires the erection of external scaffolding, and I-beam cantilever scaffolding is fully used in mid-to-high-rise and high-rise buildings to meet safe and civilized construction. need. At present, when the cantilever is erected, the fixed point of the bottom pole and the limit fulcrum of the cable-stayed wire rope are mostly in the form of welded threaded steel. The material cutting and welding quality cannot be effectively guaranteed, and the use of scaffolding has hidden safety hazards.

Utility model content

In order to overcome the defects of the prior art and provide a scaffolding facility with simple structure, quick manufacture, convenient use, safety and reliability, the utility model discloses a cantilever scaffolding pole with an anti-skid device.

The utility model achieves the purpose of the invention through the following technical solutions:

A cantilever scaffolding pole with anti-skid device, including connecting rod, characterized in that: it also includes pegs, the connecting rod is made of I-shaped steel, and the pegs are formed by fixing the top of the pegs at the center of the pegs, and connecting the rods. The upper flange plate and the lower upper flange plate of the rod are respectively fixed with a peg, and the peg is attached to the bottom end of the peg and is vertically fixed on the connecting rod.

The cantilever scaffolding pole with anti-skid device is characterized in that: the peg is welded and fixed on the connecting rod, and the distance between the peg and one end of the connecting rod is ~ times the distance between the peg and the other end of the connecting rod; The length of the bolt is 7-10 times the outer diameter of the bolt, and the outer diameter of the bolt plate is 1.5-3 times the outer diameter of the bolt.

The use method of the cantilevered scaffolding pole with the anti-skid device is characterized in that: the following steps are performed in sequence:

① Setting the stud: I-shaped steel is used as the connecting rod, and the top of the stud is fixed at the center of the stud to form a stud.

On the upper flange plate and the lower upper flange plate of the connecting rod, respectively locate and pay out the installation position of the first outer frame vertical rod and the position of the limit fulcrum of the cable-stayed wire rope. The installation position and the position of the limit fulcrum All of them are used as positioning positions. After the pay-off is completed, the bottom ends of the bolts are attached and fixed to the positioning positions on the upper flange plate and the lower upper flange plate of the connecting rod respectively. After the welding construction is completed, it must be Check welding quality;

② Hoisting: tie the wire rope to the stud of the stud, pull the wire rope and hoist the connecting rods by lifting machinery (such as reverse chains, cranes, etc.), and assemble them into scaffolding one by one. and anti-slip effect.

The use method of the cantilever scaffolding pole with anti-skid device is characterized in that:

In step ①, the stud is welded and fixed on the connecting rod, and the distance between the stud and one end of the connecting rod is 5 to 20 times the distance between the stud and the other end of the connecting rod; the length of the stud is 7 to 10 times the outer diameter of the stud. , the outer diameter of the plug disk is 1.5 to 3 times the outer diameter of the plug column.

In the construction of the I-beam cantilever scaffolding, the cantilevered layer frame body needs to be set with a fulcrum to prevent it from sliding and unstable; after the installation of the cable-stayed wire rope is completed, a limit device is set to prevent it from sliding out of function. By adopting the utility model, it is possible to combine the scaffold erection layout diagram, and by welding the studs at the corresponding positions on the cantilevered I-beam, to ensure the construction quality of the fixed point of the bottom pole of the scaffold and the limit fulcrum of the oblique-pulled steel wire rope, and to ensure the safety of the cantilevered scaffolding. The I-beam after welding the fulcrum can be reused.

The utility model has the following beneficial effects:

1. The finished stud is welded to the I-beam to complete the construction. Compared with the traditional steel bar cutting and cutting, and then welding construction, a lot of manpower is saved;

2. The construction quality of stud welding is more reliable, which can eliminate the potential safety hazards caused by the uneven quality of traditional welding construction;

3. When the stud of the cylinder is used as a limiting device, it can minimize the wear of the cable-stayed wire rope;

4. Use studs as fixed fulcrum and limit device, which is more beautiful and corrosion-resistant.
