Safe and practical tread board for realizing simple and convenient disassembly and assembly of temporary staircase in construction site

Abstract

The invention relates to a safe and practical tread board for realizing the simple and convenient disassembly and assembly of a temporary staircase in a construction site, comprising a tread steel board and steel tube rings, wherein the outer side of the tread steel board is turned downwards, the inner side of the tread steel board is turned upwards, and one steel tube ring used for penetrating in a tread steel tube is welded at each of the both sides of the back surface of the tread steel board respectively. The tread steel board is a steel board with patterns which are 3 mm thick, as well as is 900 mm long and 250 mm wide. The inner side and the outer side of the tread steel board are turned upwards by 30 mm and turned downwards by 30 mm respectively. The two steel tube rings on the back surface of the steel board have a diameter of 50 mm. According to the invention, the tread steel board which is convenient to disassemble and assemble is additionally arranged on the basis of the original temporary staircase which is erected by all-steel tubes, thus overcoming the defect that the original tread steel board composed of double steel tubes is bad in anti-slide force and extremely easy to cause safety accidents. Except the tread steel board, the whole temporary staircase structure can be formed by standard scaffold steel tubes and fasteners, and is simple and convenient to erect.

Description

technical field [0001] The invention relates to a temporary staircase erected on a building site, in particular to a tread plate of a temporary staircase which has a flexible erection form and is suitable for various construction stages such as on-site foundation pit excavation and structural construction. Background technique [0002] In the current building construction process, temporary stairs erected during foundation pit excavation, structure construction and other construction stages can be seen everywhere. Most of the short-term use of bamboo escalators, wooden escalators, etc. Temporary stairs made of all steel pipes, or plywood-faced temporary stairs made of wood, and temporary stairs made of section steel. The various construction temporary stairs mentioned above have their own advantages and disadvantages: Bamboo escalators and wooden escalators are suitable for occasions with extremely short service life and small height difference. They have small bearing capac...

AI Technical Summary

Problems solved by technology

The various construction temporary stairs mentioned above have their own advantages and disadvantages: Bamboo escalators and wooden escalators are suitable for occasions with extremely short service life and small height difference. They have small bearing capacity and are generally used by a small number of people. Inverted; the temporary stairs built with wood, the appearance is relatively neat, but the production is slow, inconvenient to disassemble and assemble, not easy to recycle, and the consumption of wood is not environmentally friendly. It is suitable for occasions where only two, three or four steps are required; made of steel Stairs need to be customized according to the installation location, which is not conducive to repeated use, and the cost is high; the temporary stairs assembled by all-steel steel fasteners are common at the construction site, and the scaffolding tubes commonly used on the construction site are mainly used, and the erection angle and height can be adjusted. Set up according to actual needs, flexible set up, easy disassembly and assembly, but because the steps are made of double round steel pipes, the anti-slip force is poor, especially in humid environments, it is easy to cause slipping and falling accidents for users, and the safety needs to be improved
