Steel structure assembled embedded part and construction method thereof

Abstract

The invention relates to a steel structure assembled embedded part and a construction method thereof, belonging to the technical field of building installation. The steel structure assembled embedded part comprises a plurality of embedded screws, the upper threaded parts of the embedded screws are jointly provided with a top template; the embedded screws are fixedly connected with the top template through clamping nuts 1 respectively positioned above the top template and packing nuts 1 positioned below the top template; the lower threaded parts of the embedded screws are jointly provided with a bottom template; the embedded screws are fixedly connected with the bottom template through clamping nuts 2 respectively positioned above the bottom template and packing nuts 2 positioned below the bottom template; the tail ends of the lower threaded parts of the embedded screws are provided with regulating bases, and the bottoms of the regulating bases are respectively fixed with embedded irons. The invention can decrease the work types of foundation construction, lower the technical requirements for construction, shorten the construction period and enable the foundation construction to have stable quality.

Description

technical field [0001] The invention relates to a steel structure composite embedded part and a construction method thereof, belonging to the technical field of building installation. Background technique [0002] There are two types of traditional steel structure embedded parts: single embedded screw structure and embedded part group structure composed of on-site welded and fixed bracket structure. The single pre-embedded screw is installed after the construction of the foundation reinforcement, and the pre-embedded screw is welded to the foundation main reinforcement through the lap joint of the auxiliary reinforcement. This fixing method will first destroy the structure of the foundation main reinforcement; Affect the material material of the embedded screw; moreover, the embedded screw will interfere with the foundation steel bar during installation, which will affect the installation progress; and the verticality and horizontal height of the embedded screw fixed by lap ...

AI Technical Summary

Problems solved by technology

The single pre-embedded screw is installed after the construction of the foundation reinforcement, and the pre-embedded screw is welded to the foundation main reinforcement through the lap joint of the auxiliary reinforcement. This fixing method will first destroy the structure of the foundation main reinforcement; Affect the material material of the embedded screw; moreover, the embedded screw will interfere with the foundation steel bar during installation, which will affect the installation progress; and the verticality and horizontal height of the embedded screw fixed by lap welding cannot be adjusted arbitrarily; Finally, because the top of the single-rod pre-embedded screw is not fixed firmly and has poor stability, it is easy to deform or shift during formwork or concrete pouring construction, and the installation accuracy is always out of control

[0003] On-site welding of fixed bracket type embedded parts group, the main material of the fixed bracket is angle steel, and the construction is carried out before the installation of steel bars. First, the angle steel is welded into a fixed bracket of a certain size, and then the embedded screw is fixed on the bracket to form a stable structure. Compared with the previous one, the construction quality of this embedded part method has been greatly improved, but this kind of on-site welding bracket method: firstly, the on-site welding bracket has a large and complicated workload, poor stability, and it is difficult to adjust the bracket after welding and fixing. ; secondly, welding and fixing between the welded bracket and the pre-embedded screw, so that the pre-embedded screw has no adjustment margin; moreover, the structure of the welded bracket is complex and has many components, which seriously affects the subsequent foundation reinforcement and foundation formwork construction, making the installation Accuracy cannot be guaranteed
