Inserted type outer frame L-type steel wall connecting piece structure free of scaffold hole and construction method thereof

Abstract

The invention discloses an inserted type outer frame L-type steel wall connecting piece structure free of a scaffold hole and a construction method thereof and relates to a construction device and a construction method thereof. The wall connecting piece structure comprises an outer frame and a wall connecting piece, wherein the outer frame is mainly composed of an upright column, a large cross rod and a small cross rod; the wall connecting piece comprises a wall connecting rod and L-type steel, one end of the wall connecting rod is connected with the upright column of the outer frame, the other end of the wall connecting rod is welded with the short side of the L-type steel, and the long side of the L-type steel is embedded in a main body reinforced concrete structure. The construction method comprises the steps that A, the wall connecting piece is manufactured in an off-site manner; B, the outer frame is mounted; C, the wall connecting piece is mounted; D, the main body structure concrete is poured; E, the wall connecting piece is connected with the outer frame; F, the wall connecting piece is dismantled; G, outer wall repairing is carried out; H, the outer frame is dismantled. According to the inserted type outer frame L-type steel wall connecting piece structure free of the scaffold hole and the construction method thereof, the position of the wall connecting piece is not needed to be changed for the second time, and the construction progress is accelerated; no wall holes and scaffold holes are penetrated, the risk of outer wall leakage is reduced, the safety performance is high, material is saved, and the wall connecting piece structure is applicable to connecting an edge beam, a shear wall, a column position with the outer frame.

Description

technical field [0001] The invention relates to a building construction device and a construction method thereof, in particular to a hand-eye-free insertion-type outer frame L-shaped steel wall connection structure and a construction method thereof. Background technique [0002] At present, most of the steel pipe scaffolding wall parts used in construction projects are pre-embedded short steel pipes in the main structure, using rigid fasteners, and connecting with the frame body through small cross bars to stabilize the frame body and resist wind load. But this kind of steel pipe scaffolding and wall parts bring a lot of inconvenience to the construction: [0003] 1. Holes and hand holes are left on the external walls, which bring hidden dangers of external wall leakage; [0004] 2. It is necessary to replace the position of the wall parts twice to complete the construction such as: railing installation, exterior window installation and exterior wall decoration, which not...

AI Technical Summary

Problems solved by technology

But this kind of steel pipe scaffolding and wall parts bring a lot of inconvenience to the construction:

[0003] 1. Holes and hand holes are left on the external walls, which bring hidden dangers of external wall leakage;

[0004] 2. It is necessary to replace the position of the wall parts twice to complete the construction such as: railing installation, exterior window installation and exterior wall decoration, which not only easily leads to unnecessary safety risks, but also affects the safety of railing installation, exterior window installation and exterior wall decoration. progress and quality;

[0005] 3. Since the scaffolding (that is, the outer frame) is connected with the short steel pipe embedded in the main structure through steel fasteners, the harm caused by this unreliable rigid tie has increasingly affected the normal construction of the project

[0006] The Chinese patent with the publication number CN101892738A discloses "A Pre-embedded Scaffold Wall Part and Its Construction Method". The maintenance problem of the leakage of the scaffolding eye on the exterior wall after delivery, but the patent still needs to replace the position of the wall parts twice to complete the construction of railing installation, exterior window installation and exterior wall decoration, and when the outer frame and wall parts are removed, The operation is also troublesome, the construction progress is still slow, and the safety performance is still not high enough
