A scaffold that can be built on an inclined plane

Abstract

A scaffold capable of being set up on an oblique plane comprises supporting legs erected at the four corners of a scaffold body, transverse supports transversely connected among the supporting legs and oblique supports connected among the supporting legs in the oblique direction. The supporting legs, the transverse supports and the oblique supports are connected to form a truss structure; the transverse supports are of a multi-layer structure and are horizontally arranged, and pedals can be erected on the transverse supports to serve as operation platforms; the supporting legs are steel tubes, retractable rods are sleeved with the lower ends of the supporting legs, and a plurality of ring locking grooves are evenly formed in the outer walls of the retractable rods; locking mechanisms are arranged on the outer walls of the supporting legs to lock the retractable rods into the supporting legs; and each locking mechanism comprises a hinged support, a cam, a locking key and a handle, the hinged supports are fixed to the supporting legs, and the cams, the locking keys and the handles are connected into wholes and rotate on the hinged supports with cam shafts as the axes. According to the scaffold, the scaffold can be set up at places with steps or slopes or rugged ground surfaces, the scaffold keeps vertical, and the safety of aloft work can be effectively improved.

Description

technical field [0001] The invention relates to a scaffold, in particular to a scaffold that can be built on an inclined plane. Background technique [0002] With the rapid development of the world economy, people's living standards are also improving rapidly, and now many residential buildings are developing to high-level. In the process of building residential buildings or high-altitude maintenance, it is inevitable to build scaffolding. In the past, many long bamboo poles were used to connect horizontally, vertically and obliquely to form a truss structure, and pedals were installed on the cross braces for high-altitude operations. Most of the bamboo poles are fixed with wear-resistant ropes. Such scaffolding is very unsafe. In recent years, scaffolding generally uses steel structures as supporting legs, cross braces and diagonal braces, and the corresponding connectors are prefabricated to improve the installation efficiency of scaffolds.

Problems solved by technology

In the process of building residential buildings or high-altitude maintenance, it is inevitable to build scaffolding. In the past, many long bamboo poles were used to connect horizontally, vertically and obliquely to form a truss structure, and pedals were installed on the cross braces for high-altitude operations. Most of the bamboo poles are fixed with wear-resistant ropes. Such scaffolding is very unsafe.

In recent years, scaffolding generally uses steel structures as supporting legs, cross braces and diagonal braces, and the corresponding connectors are prefabricated to improve the installation efficiency of scaffolds. However, the construction equipment of these scaffolds is prefabricated before installation, and the connectors can only be It is fixedly installed in certain predetermined positions, and the basic shape of the scaffolding built in this way has been fixed.

Although the safety, stability and construction efficiency of such scaffolding have been greatly improved, it is not suitable for some specific places, such as on steps, slopes, and uneven ground. The length of the supporting legs is fixed, and the connection angle between the horizontal braces and diagonal braces and the supporting legs is fixed, and the erected scaffold will be inclined, which is only suitable for building on relatively flat ground.
