Pre-embedding method of pre-embedding channel steel into concrete member

Abstract

The invention discloses a pre-embedding method for pre-embedding channel steels into concrete components, wherein the notch width of the channel steels is smaller than the width of the cavity cavity, comprising the following steps: filling the cavity cavity with fluffy materials; A number of T-bolts, wherein the bolt head of the T-bolt can be clamped in the groove cavity and can be removed from the groove cavity, and the bolt rod passes through the groove; the concrete component formwork is drilled, and the shape of the drill hole, The quantity and interval match the T-shaped bolts distributed on the channel steel; fix the channel steel on the side of the concrete component formwork adjacent to the concrete component to be poured, and ensure that the bolt heads of the T-shaped bolts distributed on the channel steel are all stuck It is arranged in the groove cavity, and the bolt rods of each T-shaped bolt on the channel steel pass through each drill hole on the concrete member formwork respectively and then are locked by lock nuts; the concrete is poured so that the channel steel is pre-embedded in the concrete member. Through the above pre-embedding method, it is convenient to install and pre-embed the channel steel, and the notch exposure of the channel steel meets 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 a...

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 member. During the concrete pouring process, the concrete slurry fills the gap and blocks the notch, which eventually leads to the inability to install subsequent external brackets and other components. on the channel steel

This installation process has the following defects: the installation process is complex and time-consuming. If there is an error in the straightness or verticality of the channel steel during installation, the channel steel needs to be unbound before adjustment can be made, and the binding installation method is adopted. If the fit between the channel steel and the formwork of the concrete member is not enough, the concrete slurry will easily flow in from the gap between them during the concrete pouring process, so that the notch will be sealed
