Waterproof method after the removal of the scaffolding wall device

Abstract

The invention discloses a scaffold wall-connecting device, which comprises anchors, embedded parts, wall-connecting rods and rod fastening nuts, the embedded parts are vertically placed cuboids with cavities, and the One side of the wall has a strip-shaped opening that runs through the entire length; one end of the wall tie rod is slidably connected in the embedded part and fixedly connected with the embedded part through the tie rod fastening nut, and the other end is fixedly connected with the fastener. The waterproof method after its removal is to clean the cavity, fill the cavity with hole-filling mortar and reserve a groove on the plane at one end of the opening, fill the groove with waterproof mortar, and level the entire external wall with external wall mortar Come level. In this way, there is no need to cut the tie rods, and the finished wall tie rods can be reused, which greatly saves steel materials, increases the path of water flow, and greatly improves the waterproof performance.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a waterproofing method after dismantling a scaffolding wall device. Background technique [0002] During the construction of the building, it is necessary to do external wall painting, veneer and other operations. Therefore, the operating environment is special. Scaffolding must be erected as a construction platform for workers during construction, otherwise it will not be able to stand. As the height of modern buildings and the complexity of building facades increase, the difficulty and requirements of building scaffolding are getting higher and higher. In the prior art, a double-row fastener-type steel pipe scaffold is usually installed at the construction site, which includes multiple longitudinal horizontal rods, horizontal horizontal rods, and vertical rods. These rods form a multi-layer, multi-span frame-shaped steel Structural scaffolding. The connecting piece b...

Problems solved by technology

However, there are problems with the structure using embedded parts: first, its position accuracy is not easy to control, and the repair work in the later period is relatively large; There are difficulties in the normal installation of connecting wall parts; thirdly, when the main body of the building enters the stage of exterior wall decoration, the construction company removes the original wall connecting parts for the convenience of exterior wall construction, which causes the anti-overturning force of the frame. Seriously reduced; Fourth, the pre-embedded steel pipe connection cannot be removed due to the pre-embedded vertical steel pipe, and the masonry opening needs to be sealed later, which will bring hidden dangers to the waterproofing of the outer wall

However, the problem of the post-anchor connection is that the construction is extremely troublesome, especially the drilling operation is very troublesome: usually two expansion anchors are used, the bearing capacity is not high, it is easy to loosen, and it cannot withstand low cycle repeated loads. Strictly speaking, it cannot be included The range of rigid wall parts; if chemical anchors are used, the construction requirements are very high. During the construction process, the hole depth and diameter must be strictly controlled, and the holes must be strictly cleaned, otherwise the bearing capacity cannot be guaranteed; It is scrapped and cannot be reused, which increases the construction cost; and when it is dismantled, it must be cut with an open flame, so there is a serious fire hazard
