Description

TECHNICAL FIELD

[0001] The present application relates to a socket type disc buckle steel pipe scaffold punching steel sheet net connecting device, belongs to the technical field of building materials. BACKGROUND

[0002] Punching steel sheet net (7) and (17) are composed of punching steel sheet (2) with thickness of about 0.5mm and steel frame (9) fixed by screw (10), steel frame (9) is made with 500mm as standard module unit, general appearance specification is: 1000mm*2000mm, used for safety protection of building construction scaffold. Because punching steel sheet net has advantages of non-combustion, standardization, low damage rate, high turnover rate, appearance beauty and the like, punching steel sheet net is promoted to use in building engineering scaffold in different degrees in the whole country, and is more and more widely applied. If connection of punching steel sheet net and scaffold is unreliable, punching steel sheet net will fall off from scaffold, especially after falling off from high altitude of high-rise building, if it floats to dense area of people, not only will cause production safety accident of personal injury and death, make family suffer heavy losses, but also will cause extremely serious influence to society.

[0003] At present, the connection between the socket type disc buckle type steel pipe scaffold and the punched steel sheet net basically adopts the form of short steel pipe plus H-shaped clamp or double-hook-shaped and single-hook-shaped clamp, one end clamps or hooks the steel frame of the upper and lower two pieces of punched steel sheet net, and the other end fastens the short steel pipe on the steel pipe outside the scaffold by the fastener. The H-shaped clamp clamps the steel frame of the punched steel sheet net, while the double-hook-shaped clamp hooks the steel frame, and the single-hook-shaped clamp clamps the steel frame. The main problems of the three clamp connection forms are: 1. the steel frame is easy to fall off from the H-shaped clamp after deformation; 2. the steel frame cannot be reliably fixed after the deformation of the clamp, and the risk of falling off is greatly increased; 3. the weight of the short steel pipe plus clamp fastener type connecting piece is large, which greatly increases the load of the scaffold; 4. the thickness or deformation of the clamp makes the cumulative error increase when clamping or hooking the steel frame in the middle of the upper and lower two pieces of punched steel sheet net, which gradually leads to the consequences that the clamp of the upper layer cannot clamp the steel frame or clamps the steel frame but the connection is unreliable, and then the iron wire is used for auxiliary fixing or only the iron wire is used for binding; 5. the short steel pipe is relatively long, but it cannot be shortened to adapt to the use in various occasions, so that the head of the short steel pipe extends into the channel of the scaffold, which hinders the passage and has the safety hazard of injuring personnel; 6. when encountering special-shaped buildings or modulus that do not match, the punched steel sheet nets may overlap with each other, so that the clamp cannot clamp at the same time, and only the connecting piece or additional measures are used for fixing; 7. if the punched steel sheet net in the middle needs to be replaced, all the punched steel sheet nets above need to be removed, and after replacement, the punched steel sheet nets are reinstalled upward, which is very unfriendly to the safety maintenance of the scaffold; 8. only clamping or hooking but not locking the steel frame and the punched steel sheet, the connection reliability is low; 9. the connection between the fastener and the steel pipe is fixed by relying on the friction force, and there are many factors affecting the friction force; 10. there is no connection between the punched steel sheet nets, and there is no horizontal constraint, so there is a lot of displacement, and the integrity is poor; 11. according to the current connection mode, the protection does not form a new safety hazard; 12. the loss rate of the steel pipe fastener clamp type connecting device is high; 13. the short steel pipe plus clamp fastener type connecting device has high manufacturing and installation and maintenance cost and low efficiency, etc. SUMMARY

[0004] The present application provides a socket type disc buckle type steel pipe scaffold punched steel sheet net connecting device to solve the problems in the prior art. The device is small, flexible, easy to operate, can be quickly installed on the scaffold, is safe to use, and greatly reduces the cost.

[0005] The present invention proposes a technical solution to solve the above technical problems: the vertical poles of the socket-type disc-type steel pipe scaffold are welded with connecting plates (5) every 500 mm, and the connecting plates (5) are punched with two types of holes (3) and (4) spaced symmetrically from each other. Since there is no other connection outside the connecting plate (5) of the scaffolding outer pole, the present invention utilizes this connection space to invent a socket-type disc-type steel pipe scaffold punched steel plate mesh connecting device, which is characterized by comprising a lock buckle (12), a inner corner lock buckle (6), and a hook lock buckle (8). The lock buckle (12) is composed of two identical L-shaped steel sheets (19) with holes (20) at the long ends, which are welded back to back into one piece by a metal patch (21). The short ends of the L-shaped steel sheets (19) have symmetrical hole grooves (18), and the whole is T-shaped. The internal angle lock buckle (6) is symmetrically welded to the middle of the external angle surface of the L-shaped steel sheet (22) with holes (20) at the tail ends, and welded into one piece by a metal patch (21). The hook-shaped lock buckle (8) is made of a certain length of steel into a hook shape, and the two ends are processed into a connection and fixed shape. The principle is to insert the T-shaped bottom end of the lock buckle (12) into the outer side of the connecting plate (5) of the socket-type disc-type steel pipe scaffolding outer corner outer pole (15) and the straight section outer pole (14), insert the disc-type connector (13) into the hole (20) of the lock buckle (12) and the hole (3) of the connecting plate (5) to complete the connection, and then use the hook-shaped lock buckle (8) to respectively clamp the horizontal crossbar of the punching steel plate mesh (7) and the (17) steel frame (9), pass through the hole (16) on the punching steel plate (2) and the upper and lower hole grooves (18) of the lock buckle (12), and screw nuts (11) into the two ends of the hook-shaped lock buckle (8) to fix it. The use principle of the inner corner lock buckle (6) is the same as that of the lock buckle (12), and is used to connect the punching steel plate mesh (7) and (17) of the inner corner pole (1) of the scaffolding.

[0006] The beneficial effects of the present invention are:

[0007] The present invention is composed of a lock buckle, an inside corner lock buckle, a hook-shaped lock buckle, etc., which locks the steel frame and punched steel plate of the perforated steel plate mesh and the scaffolding at the same time, thereby realizing a reliable connection between the socket-type disc-type steel pipe scaffolding and the perforated steel plate mesh, greatly reducing the weight of the connecting parts, greatly reducing the load borne by the scaffolding body, and eliminating the safety hazards caused by the original connection device; and the perforated steel plate mesh has strong integrity, is easy for operators to master, has simple connection operation, fast construction speed, saves materials and labor, greatly reduces the use cost, and has stronger applicability, thereby greatly improving the safety performance of the connection between the perforated steel plate mesh and the socket-type disc-type steel pipe scaffold, controlling the risk of the perforated steel plate mesh falling off, protecting people's lives and property, and promoting the further improvement of the safety production situation.
