Plastering slide track device for surface finishing when pouring concrete bottom plate in hole

Abstract

A plastering slide track device for surface finishing when pouring a concrete bottom plate in a hole consists of steel pipe slide track, an angle steel support, screw stems, nuts and bottom plate top reinforcements. The steel pipe slide track is placed on the angle steel support, the lower end of the angle steel support is welded with the screw stems, the nuts are welded on the bottom plate top reinforcements, and the screw stems are screwed into the nuts. After the plastering slide track device is fixedly mounted on a concrete bottom plate to be poured, pouring elevation and surface evenness of the concrete bottom plate can be conveniently and accurately controlled by means of adjusting the heights of the screw stems, and an operator utilizes the device to primarily level out the surface of the concrete bottom plate. Before concrete is set initially, surface finishing and artificial pressure polishing of the concrete bottom plate are finished via a compacting machine. The plastering slide track device is simple in installation, convenient in use, easy in detachment and accurate in elevation and evenness control, and can be reused.

Description

technical field [0001] The invention relates to a surface plastering slide rail device used for pouring concrete bottom slabs in caves, in particular to a construction in caves that can conveniently control the elevation of surface-receiving concrete, greatly improve the surface flatness of concrete bottom slabs, and meet high-standard flatness requirements. The plastering slide rail device used for closing the surface when the concrete bottom slab is poured. Background technique [0002] In order to achieve specific functions such as traffic, flow, and structural force, the concrete floor of the underground cavern often needs to be poured with concrete. In order to meet the requirements of use, sometimes higher requirements are put forward for the accuracy of the elevation and flatness of the concrete floor, especially for some over-current tunnels, the requirements are more stringent. When pouring the concrete bottom slab in the cave, there are generally cave wall rocks o...

AI Technical Summary

Problems solved by technology

When pouring the concrete bottom slab in the cave, there are generally cave wall rocks or drainage ditches on both sides. Due to limited conditions, the elevation mark is generally used to control the elevation on the formwork or erecting bars. Workers' proficiency and sense of responsibility are used to control the flatness of the dough. There are many artificial uncertain factors, and the lack of quantitative and accurate control methods often results in uneven control of the flatness and large quality differences when different workers operate.
