AI Technical Summary

Technical Problem

In existing technologies, manually adjusting the position of the composite insulation template makes it difficult to ensure that it is positioned correctly, resulting in unstable installation.

Method used

A composite thermal insulation non-removable template positioning device was designed, comprising a base, a fixing plate, a positioning mechanism, a moving mechanism, a measuring component, and a marking component. Through the cooperation of the push-pull box, pneumatic component, and measuring component, the template is accurately positioned and marked, ensuring that the template can be directly laid on the reinforcing steel.

Benefits of technology

It achieves precise positioning of the composite insulation template without disassembly, avoiding multiple adjustments and improving the stability and efficiency of installation.

Abstract

This invention relates to the field of prefabricated building technology and discloses a positioning device for composite thermal insulation non-removable formwork in prefabricated buildings. The device includes a base and a controller. A fixing plate is fixedly installed on one side of the outer wall of the base, and nail holes are formed on the surface of the fixing plate. A protective cover is fixedly installed on the top of the base. Positioning mechanisms for positioning and installing the non-removable formwork are provided on both sides above the protective cover. Through the positioning mechanisms, this invention can drive a marker to draw a straight line on the ground. The distance of this line is the thickness of the formwork. Therefore, when moving the device, simply align the fixing plate with the straight line and align the nail holes on the surface of the fixing plate with the end point of the line to achieve precise movement of the device. At this point, the distance between the end face of the sliding box and the reinforcing steel is exactly the thickness of the formwork, ensuring that the formwork can be directly laid on the reinforcing steel without multiple adjustments, thus achieving a more accurate positioning effect.
