Embedding method for embedding box iron in concrete component

Abstract

The invention discloses an embedding method for embedding box iron in a concrete component. The width of a notch of the box iron is smaller than that of a groove cavity. The embedding method includes the following steps of filling the groove cavity with fluffy substances; distributing a plurality of T-shaped bolts in the length direction of the box iron, wherein bolt heads of the T-shaped bolts can be clamped in the groove cavity and can be detached out of the groove cavity, and bolt rods penetrate through the notch; drilling holes in a concrete component formwork, and making the shapes, number and intervals of drilled holes matched with those of the T-shaped bolts distributed on the box iron; fixing the box iron to the face, adjacent to the to-be-poured concrete component, of the concrete component formwork, ensuring that the bolt heads of all the T-shaped bolts distributed on the box iron are clamped in the groove cavity, and making the bolt rods of all the T-shaped bolts on the box iron penetrate through the drilled holes in the concrete component formwork respectively and then locked through locking nuts; pouring concrete, and embedding the box iron in the concrete component. By means of the embedding method, the box iron can be conveniently embedded, and exposure of the notch of the box iron conforms to the standard.

Description

technical field [0001] The invention relates to a method for installing channel steel in the field of building construction, in particular to a pre-embedding method for pre-embedding channel steel into concrete components. Background technique [0002] Channel steel originates from Germany HALFEN Group Company, formerly known as HALFEN Slot, was founded in 1929. After nearly a century of continuous development, HALFEN can provide customers with many product series such as: concrete anchorage system, curtain wall support system, steel reinforcement and connection system, concrete prefabricated components, etc. In 2008, HALFEN Group established a branch in China: HALFEN ( Beijing ) Construction Accessories Sales Co., Ltd., and at Shanghai , Guangzhou and Chengdu Set up an office. exist China , HALFEN products have been widely used in many domestic projects, mainly for the pre-embedding of curtain wall projects, nuclear power plants, high-speed railway trunk lines...

AI Technical Summary

Problems solved by technology

This installation process has the following defects: the installation process is complicated and takes a long time. If there is an error in the straightness or verticality of the channel steel during construction, the secondary adjustment of the channel steel is very difficult. Welding; in the process of concrete pouring, the construction has a certain impact on the steel bars and concrete component formwork, especially when using vibration equipment, it may cause deformation of the steel bar and concrete component formwork, such as causing the steel bar to bend inward and expand the mold, which will drive The channel steel welded with the steel bar is deformed inward, and there is a gap between the notch of the channel steel and the formwork of the concrete...
