Problems solved by technology

However, at present, the construction of the concrete short-leg shear wall structure still adopts the original construction method of on-site support formwork, tying steel bars, and on-site pouring of concrete. After the main structure is completed, a large number of thermal insulation layers, interior and exterior decoration, and equipment and pipeline installation are still required. Such tedious work makes the construction cost relatively large, the on-site construction procedure and management are complicated, and the final structural construction quality is not easy to be guaranteed.
In addition, the comprehensive energy consumption of the building structure in the original construction method is high, the construction method is not conducive to the environment and energy saving, the construction site is not easy to clean, and the construction noise seriously disturbs the residents

Embodiment 1

[0017] A prefabricated concrete shear wall with thermal insulation finish is formed at one time, and its composition includes: a wall body 1, the wall body is sequentially connected with an insulation layer 2, a welded steel mesh 3, a mortar bonding layer 4, and a decorative surface layer 5. Welding tie bars 6 on the welded steel mesh, the tie bars are tied to the wall, the mortar bonding layer communicates with the grouting pipe 7 and passes through the wall, and the mortar sticks The junction layer has vent holes 8 .

Embodiment 2

[0019] In the above-mentioned prefabricated concrete shear wall with thermal insulation finish, a certain length is reserved after the tie bars pass through the mortar bonding layer and insulation layer to tie with the wall hooks.

Embodiment 3

[0021] In the above-mentioned prefabricated concrete shear wall with thermal insulation finish, the thermal insulation layer is benzene board or extruded plastic board, and the decorative surface layer is ceramic tile or stone.

[0022] This product adopts the prefabricated concrete short-leg shear wall structure according to the housing industrialization construction method. The structural components are divided into structural parts in a certain way. The structural parts are factory prefabricated and hoisted and installed on the construction site.

[0023] The outermost layer of this product is the decorative surface layer, that is, the decorative surface layer is placed on the bottom of the mold during prefabrication, followed by mortar bonding layer, welded steel mesh, insulation layer and concrete shear wall. The above-mentioned structural layer and the main body The concrete shear walls of the structure are arranged in layers in factory moulds, and are prefabricated in on...

Abstract

The invention relates to a once formed precast concrete shear wall with a heat preserving veneer and a production method thereof. A building structure with an original construction way has higher comprehensive energy consumption and is not beneficial to the environment and energy saving in the construction way. The once formed precast concrete shear wall with a heat preserving veneer comprises a wall body (1) which is connected with an insulating layer (2), a welding reinforcing mesh (3), a sand pulp bonding layer (4) and an architectural surface (5) in sequence, wherein a binding bar is bound with the wall body; the sand pulp bonding layer is connected with a pulp filling pipe (7) passing through the wall body; and the sand pulp bonding layer is provided with an air exit hole (8). The invention is used as a residence industrial all-assembled type construction wall body and a production method thereof.

Description

Technical field: [0001] The invention relates to the field of design and construction of prefabricated concrete structures with thermal insulation layers and decorative surfaces, in particular to a prefabricated concrete shear wall with thermal insulation finishes at one time and suitable for housing industrialization. Background technique: [0002] Concrete short-leg shear walls have now become the most suitable structural form for residential construction. However, at present, the construction of the concrete short-leg shear wall structure still adopts the original construction method of on-site support formwork, tying steel bars, and on-site pouring of concrete. After the main structure is completed, a large number of thermal insulation layers, interior and exterior decoration, and equipment and pipeline installation are still required. Such tedious work makes the construction cost relatively large, the on-site construction procedure and management are complicated, and th...
