The anti-slip structure for construction uses steel instead of wood as the main and auxiliary keel structure

Abstract

The invention provides an anti-sliding main keel and auxiliary keel combined structure made of steel replacing wood for construction. The combined structure comprises multiple main keels and multiple auxiliary keels, wherein the main keels are arranged at intervals and the auxiliary keels are arranged above the main keels. The combined structure is characterized in that the main keels and the auxiliary keels are all made of the steel, contact surfaces of the main keels and the auxiliary keels are provided with main anti-sliding layers, and the auxiliary keels are provided with auxiliary anti-sliding layers matched with the main anti-sliding layers. The main keels and the auxiliary keels are matched through the main anti-sliding layers and the auxiliary anti-sliding layers. Therefore, after the main keels and the auxiliary keels are connected, contact portions are not prone to sliding and safety is greatly improved. The fact that steel tubes replace battens and are used for construction template supporting on the simple connection condition is possible. The wood is saved and cost is reduced. Spacing cavities are formed between inner tubes and outer tubes. When the outer pipes are extruded and partially deformed or outer surfaces of the inner tubes are corroded or dust and water are adhered to the outer surfaces of the inner tubes, free stretching and retracting of the inner tubes are not influenced.

Description

technical field [0001] The present invention relates to a kind of anti-slip structure for building with steel instead of wood as the main and auxiliary keel combination structure, more specifically, it relates to a main and auxiliary keel combination structure in which both the main and auxiliary keels are provided with anti-slip layers. Background technique [0002] During the construction process, the casting of the horizontal cement board is carried out on the formwork support, and the formwork support is composed of a main keel and an auxiliary keel. Due to the huge amount of casting work for the horizontal cement board, it is required that the main and auxiliary keels can be reused many times, and the quality of the cast horizontal cement board can be guaranteed. But the auxiliary keels in the existing formwork support are generally wooden squares, which not only wastes a large amount of timber, but also has fewer times for timber to be reused. In the process of use, ...

AI Technical Summary

Problems solved by technology

Since both the inner tube and the outer tube are square tubes, the inner tube and the outer tube are in contact with each other through four surfaces; during the engineering process, if the outer tube is damaged and deformed or the surface of the inner tube is corroded or adhered to gray water, the inner tube will be damaged. Cannot be pulled out or retracted, affecting normal use
