Mounting structure and method used for pre-burying Halfen groove into concrete member

Abstract

The invention relates to a mounting structure and method used for pre-burying a Halfen groove into a concrete member, and belongs to the technical field of building construction. The mounting structure used for pre-burying the Halfen groove into the concrete member comprises a Halfen groove body (1), a T-shaped bolt (2), a template (3), a nut (4), a gasket (5) and an anchor rod (6), the end, where a bolt rod (22) is far from a bolt head (21), of the T-shaped bolt (2) is provided with a groove (23) along a central axis of the bolt rod (22), and the direction of the groove is parallel to the central axial line of the length direction of the bolt head (22); the nut (4) is a wing-shaped nut. According to the mounting structure and method used for pre-burying the Halfen groove into the concrete member, the Halfen groove body (1) is fixed to the template (3) through the T-shaped bolt (2) and the nut (4), so that in a traditional mounting structure and method, the occurrence of the technical problems like inaccurate fixation, loosening, steel bar waste and the need to remove the Halfen groove body (1) and surface concrete in the later period is effectively solved; the accurate clamping position of the bolt head (21) in the Halfen groove body (1) is achieved, the template is convenient to install and dismount, the construction cost is lowered, and the mounting efficiency is improved.

Description

technical field [0001] The present invention relates to an installation structure and method for pre-embedding a Hafen trough into a concrete component, in particular to an installation structure and an installation method for pre-embedding a Hafen trough in projects such as pipe galleries, buildings, roads and bridges, and belongs to construction The field of construction technology. Background technique [0002] The HALFEN Trough is a built-in part for construction and an ideal fixing part for easy installation and adjustment. When in use, first embed the C-shaped groove in the concrete, and then buckle the big head of the T-shaped bolt into the C-shaped groove. After adjusting the fixed position, the components to be installed are fixed with the T-shaped bolt and nut assembly to achieve the fixing effect. Almost any component can be fixed with HALFEN channel steel, such as: support systems such as pipe brackets in pipe gallery projects, civil curtain walls, prefabricated...

AI Technical Summary

Problems solved by technology

With the existing installation structure and construction technology, during the fixing process of the Hafen Trough, two C20 steel bars about 30cm long need to be welded or bound at the upper and lower ends, resulting in a lot of waste of steel bars, which is not conducive to project cost control; installation and disassembly are difficult, When the embedded part of the wall is high, the operation platform is not set up, so it is difficult to ensure the installation quality, and the installation and disassembly must be completed with the help of wrench and other auxiliary tools; at the same time, the positioning of the HALFEN groove is not accurate, and the distance error of the HALFEN groove is large. The elevations are different, and quality problems such as tilting and loosening are prone to occur during formwork installation and concrete pouring; after formwork removal, the concrete on the surface of the Hafen Groove needs to be removed, and the removed concrete must be transported out of the site, which requires a large amount of work; after formwork removal The thickness of the concrete on the surface of the Halfen tank is uneven, with an average of about 5mm. Due to the thick surface concrete, it is difficult to accurately locate the position of the Halfen tank, which makes it difficult to remove the concrete in the later stage

Moreover, the existing installation structure uses ordinary T-bolt and nut assemblies. When the nuts are tightened, the bolts are likely to rotate with the nuts and fall out of the opening of the Hafen slot. Blocking, it is impossible to correctly judge the position angle of the bolt head of the T-bolt in the Hafen slot, which leads to the inability to realize the accurate clamping of the T-bolt and nut assembly in the Hafen slot and the matching of the T-bolt and nut assembly to the formwork and other components fixed, so the firmness of the fixing cannot be ensured

At the same time, when disassembling components such as templates, it is also prone to the situation that the bolts rotate with the nuts or cannot be disassembled normally

In addition, the existing T-shaped bolt and nut assembly uses ordinary hexagonal nuts, which must be tightened with the help of wrench and other tools during use, which is inconvenient to operate
