Embodiment 1

[0040] Embodiment 1 of the present application discloses a crack-resistant thermal insulation wall and a construction process. The anti-crack thermal insulation wall consists of thermal insulation layer and surface layer. The thermal insulation layer is made of polystyrene plastic board, and the surface layer is made of cement, anti-crack agent, and medium sand in a mass ratio of 1:1:5. The anti-cracking agent is a dispersion emulsion of wood fibers.

[0041] The construction technology of the anti-crack thermal insulation wall includes the following steps:

[0042] Brush polyurethane adhesive on the surface of the concrete layer to form an adhesive layer, and paste a polystyrene plastic board on the surface of the adhesive layer; brush fiber mortar on the surface of the polystyrene plastic board, and air dry for 15 minutes at room temperature to form a surface layer.

[0043] refer to figure 1 and figure 2, the wall construction device for brushing the adhesive layer and ...

Embodiment 2

[0054] The difference between Example 2 and Example 1 is that the surface layer is made of cement, anti-cracking agent, and medium sand in a mass ratio of 1:4:8. Brush fiber mortar on the surface of the polystyrene plastic board, and air dry for 20 minutes at room temperature.

Embodiment 3

[0056] The difference between Example 3 and Example 1 is that the surface layer is made of cement, anti-cracking agent, and medium sand in a mass ratio of 1:2:6. Brush fiber mortar on the surface of the polystyrene plastic board, and air dry for 18 minutes at room temperature.

Abstract

The invention relates to an anti-crack thermal insulation wall and a construction process. The construction process of the anti-crack thermal insulation wall comprises the following steps that polyurethane adhesive is coated to form an adhesive layer, and a polystyrene plastic plate is pasted on the surface of the adhesive layer; and fiber mortar is coated on the surface of the polystyrene plastic plate, and air-drying is carried out for 15-20 minutes at normal temperature to form a surface layer. The wall construction device for coating the adhesive layer and the surface layer comprises a supporting frame; a connecting seat is slidably connected in the supporting frame, the connecting seat is rotatably connected with an internal thread pipe, and a screw rod is in threaded connection in the internal thread pipe; the screw rod is fixedly connected with a fixing frame, and a painting wheel is rotationally installed in the fixing frame; the connecting seat is fixedly connected with a guide plate, a guide piece penetrates through the guide plate, and an inserting groove is formed in the peripheral face of the screw rod; the guide plate is provided with a separation assembly used for driving the guide piece to be separated from the inserting groove; and a driving mechanism used for driving the inner threaded pipe to rotate is arranged in the supporting frame. The problem that a brush is locally deformed due to the fact that the brush is tightly attached to the outer wall can be solved.

Description

technical field [0001] The present application relates to the field of wall construction, in particular to a crack-resistant thermal insulation wall and construction technology. Background technique [0002] At present, the thermal insulation of external walls in construction production is an important step in the construction industry, and it is also a link with a large investment. The excellent thermal insulation performance of external walls is closely related to the service life of buildings. [0003] Related technologies can refer to the Chinese utility model patent with the authorized announcement number CN208122219U, which discloses a building exterior wall brushing device, including a frame, a brushing mechanism, a paint storage box and an operating platform, and the rollers on the frame are in contact with the building exterior wall. Sliding down, the brush on the coating brush contacts the building wall, and the telescopic cylinder pushes the sliding seat to slide ...
