Problems solved by technology

At present, there are two main methods for building wall insulation. One is self-insulation of the wall, and the other is to attach an insulation layer to the ordinary wall. The second method is the main method currently adopted. There are two methods, one is Affix board-type thermal insulation products, the second is to fix it on the base wall by anchoring, and the third is to apply expanded polystyrene board slurry thermal insulation products such as the thermal insulation technology described in patent CN02153344.X, by this Although the thermal insulation effect obtained by the technology is relatively ideal, it has its own shortcomings that are difficult to overcome, that is, the construction process is complicated, the adhesion is low, and it cannot be mass-produced.
According to the "Construction Engineering Facing Brick Bond Strength Test Standard" (JGJ110-97), the average bond strength should not be less than 0.4Mpa, and it is difficult for all current insulation systems to pass this index
After the external wall is attached with a poor-strength insulation layer, the exterior brick decoration material cannot be used for the exterior finish, which conflicts with the current large number of buildings that use face brick as the exterior finish

Embodiment 1

[0037] as attached figure 1 A thermal insulation exterior wall structure, comprising base wall 1, embedded parts 2, connecting parts 3, external fixing parts 4, adhesive and thermal insulation board 5, thermal insulation board 5 is a foamed polystyrene board, bonded The embedded part 2 is fixed to the base wall 1 with an agent, the connecting part 3 is connected with the embedded part 2, and then the external fixing part 4 is connected and fixed through the foamed polystyrene insulation board.

[0038] First apply a layer of adhesive on the expanded polystyrene board to press the embedded part 2 into it, and then apply a layer of adhesive to cover the embedded part 2, so that the embedded part 2 and the adhesive form a One side is glued to the expanded polystyrene board and the other side is glued to the wall. In addition, after the connecting piece passes through the insulation board, the plastering mortar made of a mixture of water and cement is used to glue the glass fiber ...

Embodiment 2

[0059] Such as figure 1 A thermal insulation exterior wall structure, comprising base wall 1, internal embedded parts 2, connecting parts 3, external fixing parts 4, adhesive and expanded polystyrene insulation board 5, and the internal embedded parts are fixed to the base wall by adhesive 1, connect the connecting piece 3 with the embedded piece 2 and pass through the foamed polystyrene insulation board 5 to connect and fix with the external fixing piece. The embedded part is hot-dip galvanized welded mesh, the width of hot-dip galvanized welded mesh is 80mm, the wire diameter is 1.4mm, and the mesh is 200mm2; the connecting piece is double-strand galvanized iron wire; The parts are welded mesh. The embedded part is made into a net shape, which can be better integrated with the adhesive, and its bonding strength is higher. The external fixing part and the embedded part are made of the same material.

[0060] The construction process of the above thermal insulation exterior ...

Abstract

The present invention relates to a structure of heat-insulating external wall. Said structure includes base layer wall body, internal embedded component, and connecting component, and external fixing component, adhesive and foamed polystyrene heat-insulating plate, wherein the internal embedded component is fixed on the wall by adhesive, then the connected connecting component and internal embedded component are acrossed the foamed polystyrene heat-insulating plate to fixedly conntected with external fixing component. The construction technology of said heat-insulating external wall comprises the following steps: levelling base layer wall body, determing or processing and pasting polyphenyl plate on the foamed polystyrene heat-insulating plate according to the condition of the wall surface, installing the internal embedded component onto the binder, and wiping the binder and covering the internal embedded component, acrossing the foamed polystyrene heat-insulating plate by connecting component and tensioning the foamed polystyrene heat-insulating plate; pasting and compressing the foamed polystyrene heat-insulating plate onto the wall, wiping a layer of face rubber paste on the foamed polystyrene heat-insulating plate, installing external fixing component after pasting alkaliresistant mesh cloth, and then binding the external fixing component using by the connecting component, finally wiping mucilage onto the outermost layer. The invention is firm in structure, convenient in construction and low in cost.

Description

technical field [0001] The invention relates to a structure of a building thermal insulation exterior wall and a construction process thereof, in particular to a structure of a composite thermal insulation exterior wall and a construction process thereof. Background technique [0002] At present, the insulation of building walls is an important part of building energy conservation. At present, there are two main methods for building wall insulation.
