Overhanging set wall connector with steel pipes for exterior wall scaffold

Abstract

The invention discloses an overhanging set wall connector with steel pipes for an exterior wall scaffold. The overhanging set wall connector comprises a set wall connector, an embedded sleeve and a set wall connector fixing part. A fixing end on the left side of the set wall connector is subjected to cold bending by a 180-degree angle to form a hook, the set wall connector is horizontally arranged, the right side of the set wall connector is downwardly bent, two bolt holes are formed in the middle of the set wall connector fixing part, the fixing end on the left side of the set wall connector penetrates the two bolt holes formed in the middle of the set wall connector fixing part, an external upright rod is perpendicularly fixed by the aid of bolts, a 'U'-shaped groove is formed in an orifice of the embedded sleeve, the downwardly bent portion on the right side of the set wall connector is inserted into the embedded sleeve, and a horizontal pipe fitting at the front end of the bent portion on the right side of the set wall connector is fixedly clamped in the 'U'-shaped groove. The overhanging set wall connector has the advantages that stable and firm connection effects can be realized, materials can be saved, the overhanging set wall connector can be recycled and is good in safety, the exterior scaffold erecting efficiency can be effectively improved, potential safety hazards can be reduced, and the engineering cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a cantilevered steel pipe outer wall scaffold connecting wall piece. Background technique [0002] At present, the commonly used methods for connecting wall parts of steel pipe scaffolding external walls include steel pipe fastener method, post-anchoring method, steel bar and steel pipe welding method, etc. These rigid connection methods generally have the following disadvantages: 1. When the steel pipe fastener method is used to connect, the fastener is easy to get loose, and the positioning of the scaffold pole is prone to deviation. 2. When using expansion bolts to fix iron plates (welded with steel pipes), ① the bearing capacity is not high, easy to loosen, and cannot bear repeated loads; ② bolts cannot be reused, and the cost is high. 3. When the welding method of pre-embedded steel bars and steel pipes is adopted, the effective welding area of ...

AI Technical Summary

Problems solved by technology

These rigid connection methods generally have the following disadvantages: 1. When steel pipe fasteners are used for connection, the fasteners are easy to loosen, and the positioning of the scaffold pole is prone to deviation

2. When using expansion bolts to fix iron plates (welded with steel pipes), ① the bearing capacity is not high, easy to loosen, and cannot withstand repeated loads; ② bolts cannot be reused, and the cost is high

3. When the welding method of pre-embedded steel bars and steel bars is adopted, the effective welding area of ​​steel tubes and steel bars is small, it is difficult to integrate, and the welding quality is difficult to guarantee, which affects the connection strength

[0003] In the field construction, there are often related problems such as non-standard installation of shaped wall parts, non-vertical frame poles, and inaccurate control of the distance between the frame and the wall. Ordinary shaped wall parts are pre-embedded and then installed. method, the pre-embedded stereotyped wall parts cannot be removed after the frame body is removed, resulting in waste of materials
