Description

A mortise and tenon type scaffolding diagonal bracing system

technical field

The utility model relates to a support system of a scaffold used in construction engineering, in particular to a mortise and tenon type scaffold diagonal bracing system.

Background technique

Scaffolding is a variety of supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. Existing scaffolding systems mainly include: fastener type, bowl buckle type, wheel buckle type, disc buckle type, socket type and mortise and tenon type, etc. Although each kind of scaffold has its own advantages, the mortise and tenon type scaffold has its own advantages. Higher bearing capacity, better safety, and faster loading and unloading speed have been vigorously promoted. The mortise and tenon scaffold is mainly composed of a horizontal bar with a mortise and a vertical bar with a mortise. Because the cross section of the mortise is small at the bottom and large at the top, the mortise and tenon scaffold is self-locking, and there is no slippage of the nodes. At the same time, the mortise and tenon The scaffold nodes are three-sided contact force, which has higher safety compared with other point contact force scaffolds. When installing it, you only need to insert the cross bar into the mortise of the vertical bar, and when disassembling, you only need to knock out the cross bar from the bottom surface, so the tenon-tenon scaffold is easy to install and disassemble, and the construction speed is fast. Although the mortise and tenon scaffold has a lot of advantages mentioned above, as a system with a force bearing method different from that of fasteners and other scaffolds, its diagonal bracing system still uses the fastener type scaffold, so that the mortise and tenon scaffold cannot become a complete system independently. Bring inconvenience to its promotion and use. At the same time, it is proved by experiments that the bearing capacity of the mortise and tenon scaffold has a large difference with or without diagonal braces. Therefore, in order to improve the safety of the mortise and tenon scaffold and improve its system, it is necessary to propose a mortise and tenon scaffold. The supporting system ensures that the mortise and tenon scaffolding can be applied to various projects more safely and conveniently.

The technical solution adopted by the utility model to solve the technical problems existing in the known technology is: a mortise and tenon type scaffolding bracing system, including a short screw connecting the bracing and a long screw connecting the bracing intersecting with it, the long screw The connecting brace is located on the outer side of the short screw connecting brace; the upper and lower ends of the short screw connecting brace are penetrated by a short screw perpendicular to it, and the inner end of the short screw is fixed with a tenon I. The tenon I is assembled in the corresponding central mortise socket, and the outer end of the short screw is connected with the lock nut I; The inner end of the screw rod is fixedly connected with tenon II, and the tenon II is assembled in the corresponding central mortise socket, the outer end of the long screw rod is connected with a lock nut II, and the middle part of the long screw rod is connected with a limit nut, The limit nut and the lock nut II are respectively locked on both sides of the long screw connecting brace; the short screw connecting brace and the long screw connecting brace are connected by a central connecting screw at the intersection .

The advantages and positive effects that the utility model has are:

1) The connection between the diagonal brace and the vertical rod still adopts the mortise and tenon structure, without changing the original central socket, the connection and disassembly are convenient, the erection efficiency is high, labor and time are saved, and the installation accuracy is high; the diagonal brace node It is perfectly combined with the original mortise and tenon scaffolding, and at the same time makes the tenon and tenon scaffold a complete system.

2) The structure is safe and reliable. The joints are combined with diagonally braced wedge-shaped mortise and vertical rod wedge-shaped mortise. High, with reliable self-locking ability.

3) Large bearing capacity, reasonable mortise and tenon structure, strong stability, and good mechanical performance.

4) Good comprehensive benefits, simple manufacturing process, low cost, standardized component series, convenient transportation and management, and less investment in the later stage.

To sum up, the utility model can cooperate with the tenon-tenon scaffolding system, which can make the tenon-tenon scaffolding system more complete, so that it can be used safely, conveniently and quickly in various construction projects. Moreover, the diagonal bracing node uses less material, has simple manufacturing process, fast installation speed, small deformation after the screw is tightened and fixed, no slippage problem, and is safe and reliable.
