Light energy-conservation large-module combined exterior wall and method of manufacturing the same

Abstract

The invention relates to a light energy-saving large module combined-type external wall body and a preparation method thereof. The wall body board is divided into two blocks for manufacture; a technical column is added in the middle; the 10 mm that depth minus width is the clearance for wall body installation and alignment; the total thickness of the wall body is 250 mm; the wall body is filled with light thermal insulating mortar; the external wall body is formed by a strengthening surface layer of two external wall surfaces, a double-layer thermal insulation board nested on the inner side of the surface layer, and a layer of cavity left in the middle; and a steel mesh is arranged in the strengthening surface layer of the two external wall surfaces, and is positioned on the surface layer by a retaining frame. The external wall body and the preparation method fully use the air layer, enhance the thermal insulation effect, save the heat insulating material, and prevent the phenomenon of rainwater infiltration in the wall body due to the cracks of the external wall. The air chamber in the thermal insulation board accounts for 30 percent of the sectional area of the thermal insulation board; the material can be saved by 30 percent by using the polystyrene foam as the heat insulating material; and the material can be saved by 20 percent by using the plastic board as the heat insulating material.

Description

Technical field: [0001] The invention relates to a light-weight and energy-saving large modular combined outer wall body and a preparation method thereof. Background technique: [0002] At present, the commonly known construction procedures of ordinary buildings all carry out the frame construction of columns, beams and roofs first, and after the formwork is removed, the outer wall is filled with blocks and other masonry, and then the benzene board insulation layer is hung, and the wall is plastered in multiple layers. The disadvantages are: the thermal insulation material and the wall are easy to form cracks, layers, and peeling. Some large modules with thermal insulation performance are also filled in the frame, and the gaps formed need to be filled.

[0002] At present, the commonly known construction procedures of ordinary buildings all carry out the frame construction of columns, beams and roofs first, and after the formwork is removed, the outer wall is filled with blocks and other masonry, and then the benzene board insulation layer is hung, and the wall is plastered in multiple layers. The disadvantages are: the thermal insulation material and the wall are easy to form cracks, layers, and peeling. Some large modules with thermal insulation performance are also filled in the frame, and the gaps formed need to be filled. Columns and beams have no insulation or column Separate measures are taken for the insulation of the beams, and the on-site operations are cumbersome during construction, with many wet operations, and there are technical hidden dangers in quality

The block filling site construction in the existing external wall frame is cumbersome, there are many wet operations, the insulation material and the wall are easy to form layers and cracks, and the seal between the large module wall and the column beam is difficult, etc. Construction technology and building structure technology ills
