Description
技术领域technical field
本实用新型涉及建筑施工技术领域，具体涉及一种可以拆卸重复使用的工具式外脚手架螺栓连墙件，适用于各类现浇混凝土多层、高层建筑外脚手架连墙件施工。The utility model relates to the technical field of building construction, in particular to a tool-type external scaffold bolt-connected wall part that can be disassembled and reused, which is suitable for the construction of various cast-in-situ concrete multi-layer and high-rise building external scaffold wall parts.
背景技术Background technique
连墙件是指连接脚手架与建筑物的构件，能够传递拉力和压力，是脚手架的重要组成部分。国内外发生的脚手架倒塌事故，基本都是由于连墙件设置不足或连墙件被拆除后未及时补设引起。脚手架的失稳通常分为整体失稳和局部失稳。其中整体失稳是脚手架失稳的主要破坏形式，破坏始于无连墙件、横向刚度差或初始弯曲较大的横向框架。而设置合理、承载力高、构造符合要求的连墙件，对计算单元的计算跨度的改善和横向刚度的提高，均起直接作用，因而对脚手架的整体稳定性起重要作用。The wall parts refer to the components connecting the scaffold and the building, which can transmit tension and pressure, and are an important part of the scaffold. Scaffolding collapse accidents at home and abroad are basically caused by insufficient setting of connecting wall parts or failure to repair the connecting wall parts in time after being removed. The instability of scaffolding is usually divided into overall instability and local instability. Among them, the overall instability is the main failure form of the scaffold instability, and the failure starts from the transverse frame without wall parts, poor transverse stiffness or large initial bending. The wall parts with reasonable setting, high bearing capacity and satisfactory structure can directly affect the improvement of the calculation span of the calculation unit and the improvement of the transverse stiffness, and thus play an important role in the overall stability of the scaffold.
《建筑施工扣件式钢管脚手架安全技术规范》(JGJ130-2011)第6.4节对连墙件作了具体规定，对24m以上的单、双排脚手架必须采用刚性连墙件。刚性连墙件指的是采用钢管、扣件或预埋件组成的连墙件。但规范中并未具体规定刚性连墙件的做法，导致目前各地刚性连墙件的做法不一，主要有预埋钢管法、后锚固法、箍柱法和预埋铁板法等，部分做法存在安全隐患。Section 6.4 of the "Safety Technical Specifications for Fastener Type Steel Pipe Scaffolding in Building Construction" (JGJ130-2011) has specific regulations on the wall parts. For single and double-row scaffolds over 24m, rigid wall parts must be used. Rigid wall parts refer to wall parts made of steel pipes, fasteners or embedded parts. However, the specification does not specifically stipulate the method of rigid wall parts, resulting in different methods of rigid wall parts in different places, mainly including pre-embedded steel pipe method, post-anchor method, hoop column method and pre-embedded iron plate method, etc., some methods There are security risks.
常规预埋钢管连墙件埋设在梁顶面，影响砌体、抹灰、涂料等外墙施工，钢管预埋件形成的架眼需要修补，二次改设连墙件。传统的钢管预埋连墙件存在以下不足：修补洞口造成渗水的质量通病，由于修补洞口而拆除传统钢管连墙件存在的安全隐患，以及预埋的钢管浪费较大。Conventional pre-embedded steel pipe connecting wall parts are buried on the top of the beam, which affects the construction of external walls such as masonry, plastering, and paint. The traditional steel pipe pre-embedded wall parts have the following disadvantages: the common quality problem of water seepage caused by repairing the hole, the safety hazards of removing the traditional steel pipe wall parts due to the repair of the hole, and the waste of pre-embedded steel pipes.

(5)紧固连接螺栓2及连接外脚手架(5) Tighten the connecting bolt 2 and connect the outer scaffold
将连接螺栓2有外螺纹的一端旋进预埋件1内，在将脚手架钢管4用扣件与外脚手架立杆扣紧。这样就完成了连墙件系统的连接。Screw one end of the connecting bolt 2 with the external thread into the embedded part 1, and fasten the scaffold steel pipe 4 with the fastener and the outer scaffold pole. This completes the connection of the wall fitting system.
(6)连墙件的拆卸(6) Removal of wall parts
要拆除外架时，先松开扣件，逐层再将整个连墙件系统从预埋件1中旋出即可。预埋件封盖5、连接螺栓2、插销螺丝组件3、脚手架钢管4进行适当保养，即可应用到另一工程中，整套连墙件中损耗的仅是预埋件1，其余材料均可重复使用。When the outer frame is to be removed, first loosen the fastener, and then unscrew the entire wall connecting system from the embedded part 1 layer by layer. The embedded part cover 5, the connecting bolt 2, the plug screw assembly 3, and the scaffold steel pipe 4 can be applied to another project after proper maintenance. In the whole set of wall parts, only the embedded part 1 is lost, and other materials can be used. reuse.
