A method for installing embedded parts of Hafen groove in aluminum alloy formwork construction

Abstract

The invention provides an aluminum alloy template construction Hafen groove embedded installation method. The method comprises the steps that a steel wire rope with an anchor block and a tensioner areused for tightly attaching a Hafen groove to an aluminum alloy template and fixed, spiral tensioners on the two sides of the aluminum alloy template and an anchor plate in the Hafen groove are connected together through a steel wire rope and a steel wire rope clamp, the spiral tensioners are rotated to tension the steel wire rope, the Hafen groove is pressed to the template face, displacement iscontrolled by a limiting block, concrete embedded Hafen groove positioning is accurate, an embedded part is flush with the concrete face, and Hafen groove installation precision and quality are ensured. The steel wire ropes, clamp, spiral telescopic tensioners, limiting block, a toothed anchor plate with a spring and other main components used in the method can be manufactured to be molded products, can be assembled and disassembled, are convenient to assemble and disassemble and can be repeatedly used after being disassembled.

Description

technical field [0001] The invention belongs to the technical field of installation and construction of halfen groove embedded parts when aluminum alloy formwork is used for construction of a comprehensive pipe gallery, and in particular relates to a method for installing halfen groove embedded parts in aluminum alloy formwork construction. Background technique [0002] The embedded parts of the pipeline bracket support in the comprehensive utility gallery mostly adopt the Halfen groove, and the Halfen groove has its own anchor bolt. The Hafen trough is buried on the concrete shear wall of the pipe gallery, and is pre-embedded before the shear wall reinforcement is bound and the formwork is installed. After the concrete is poured, the pre-buried Hafen groove should be positioned accurately, the verticality or levelness should meet the specification requirements, and the groove should be flush with the concrete shear wall. The pre-embedded positioning and fixing of the Hafen...

AI Technical Summary

Problems solved by technology

[0003] (1) In order to ensure the accurate positioning of the Hafen trough, a large number of positioning support steel bars need to be welded, which wastes materials and man-hours, and the positioning accuracy is difficult to guarantee;

[0004] (2) It is difficult to realize the tight fit between the notch and the formwork by welding the support ribs, and the length of the support ribs is not easy to control

If it is too long, the aluminum formwork will not be installed or the formwork will be deformed; if it is too short, there will be a gap between the notch and the formwork and it will be filled with concrete. Time-consuming and labor-intensive, the quality is not guaranteed;

[0005] (3) The positioning and support of the HALFEN Trough is entirely realized by the support of the steel reinforcement in the shear wall. During the concrete pouring and vibration process, once the steel bars are displaced, the HALFEN Trough will also be displaced, and its installation deviation will also increase;
