Description

A New Scaffolding System

technical field

The invention relates to equipment for building construction, in particular to a novel scaffolding system which is convenient and quick to install and disassemble.

Background technique

Scaffolding is well known for use in the construction, restoration or maintenance of buildings. Scaffolding provides workers with a working platform to secure access areas of the building. Scaffolding can also form a safety barrier, reducing the possibility of workers, tools, loose materials and debris falling from the confines of the scaffolding. Therefore, it is important to use scaffolding to ensure the safety of the construction site.

Conventional scaffolding generally includes a system of tubular metal pipes joined together and tied to the building to form the overall scaffold, the tubular metal pipes are assembled together by bolted joints, and the scaffolding boards are also bolted to the scaffolding frame. The installation and disassembly of this prior art scaffolding is relatively complicated, and many auxiliary tools are required. In addition, scaffolding installation requires experienced scaffolding installers. Therefore, for large structures, many skilled workers are needed, time and cost to safely build scaffolding.

For example, the Chinese utility model patent No. 201220647411.6 discloses a scaffold connector, which includes a main body with a C-shaped tubular cross-section, and the two sides of the main body are all warped to form connecting ears, and the connecting ears are connected by bolts , When installing, put the two poles into the connector and fasten them with bolts. The connecting piece needs to be tightened with a wrench when the scaffold is built, which is cumbersome and laborious to operate. In addition, the connecting piece is in a non-fixed installation mode, and different situations may occur when different workers install it. It is solid, and experienced workers are required to operate when building the entire scaffold.

Contents of the invention

The present invention mainly solves the problems of troublesome installation and disassembly of existing scaffolds, time-consuming and labor-intensive operation, and high requirements for operators, and provides a new type of scaffolding system that is convenient and quick to install and disassemble, and has low operation requirements.

The scaffolding system of the utility model is fastened and connected by fastening. Compared with the bolt fixing method, the construction and disassembly are quicker and more convenient, and there is no need to use many auxiliary tools, and even non-skilled workers can easily build the scaffolding. The scaffolding plate is buckled on the cross bar by the first locking limit pin at one end, and pressed on the cross bar by the second locking limit pin at the other end, so that the scaffolding plate is fastened between the cross bars, easy to install and disassemble .

As a preferred solution, the first locking and limiting pin has an arc-shaped pointed structure, an anti-off plate is provided on the rear end of the first locking and limiting pin, and a front end of the first locking and limiting pin is provided with An anti-off protrusion, a first locking hole is provided on one end surface of the scaffolding board, a second locking hole is provided on the end surface inclined downward, and the inner arc surface of the first locking limit pin faces the hook Pass through the first locking hole and the second locking hole. The first locking pin and the hook together form a claw structure with a small opening. When installing, the cross bar pushes up the first locking pin, and the first locking pin moves backward, making the opening larger. As the cross bar is put into the hook, the first locking locating pin lifted by the cross bar rises to a certain height and then falls around the cross bar automatically, so that the first locking locating pin and the hook jointly embrace the cross bar to complete Lockout function. During disassembly, as long as the first locking positioning pin is pulled up, the locked state can be released.

As a preferred solution, a convex surface is formed in the middle of the second locking locating pin, an anti-off block is formed by bending at the rear end of the second locking locating pin, and an anti-off protrusion is provided on the front end of the second locking locating pin.
