AI Technical Summary

Problems solved by technology

This process uses multiple pieces of polystyrene boards to be combined and pasted on the surface of the wall, which improves the thermal insulation effect of the wall. The flatness of the polystyrene board is different. When pasting the polystyrene board, there will often be gaps or uneven edges at the joint between the board and the board. In this way, after hanging the net and covering the surface, local unevenness can be formed. After a period of use, will crack at seams and edges, causing rainwater to seep through

Embodiment 1

[0014] The construction process of the expanded polystyrene board for the external insulation layer of the wall, the process steps are:

[0015] (1) Base wall treatment, clearing the floating ash, floating soil, oil stains and other wastes that hinder bonding on the surface of the base wall.

[0016] (2) Smear the bottom surface of multiple polystyrene boards with mastic, and then paste multiple polystyrene boards on the base wall. When pasting, leave a gap of 5mm between the polystyrene boards and the polystyrene boards.

[0017] (3) Fill the polystyrene boards, use a polyurethane glue gun to inject polyurethane glue into the gaps between the polystyrene boards, make the polyurethane foam in the gaps between the polystyrene boards, and fill the gaps.

[0018] (4) Grinding, so that the outer surface of the filled polyurethane foam is on the same plane as the outer surface of the polystyrene board.

[0019] (5) Hang the grid cloth, smear the outer surface of the polystyrene bo...

Embodiment 2

[0021] Embodiment 2 is basically the same as Embodiment 1, except that the gap between polystyrene boards in step (2) is 10 mm, and the thickness of the cement in step (5) is 2.5 mm.

Embodiment 3

[0023] Embodiment 3 is basically the same as Embodiment 1, except that the gap between polystyrene boards in step (2) is 15 mm, and the thickness of the cement in step (5) is 3 mm.

Abstract

The construction process of the expanded polystyrene board for the external insulation layer of the wall, the process steps are: base wall treatment; plaster the bottom surface of the polystyrene board, and paste it on the base wall. When pasting, make the polystyrene board and polystyrene Leave a gap of 5-15mm between the boards; fill the gap between the polystyrene boards with polyurethane glue, make the polystyrene board foam in the gap, and fill the gap; the polyurethane foam filled in the gap The outer surface of the foam is polished so that the outer surface of the polyurethane foam is on the same plane as the outer surface of the polystyrene board, which increases the overall performance of the polystyrene board; the outer surface of the polystyrene board is covered with cement, and then spread on the grid cloth , the thickness of the cement is 2-3mm. The advantages of the present invention are: a plurality of small polystyrene boards are connected together through polyurethane foaming, and the outer surface of the polyurethane and polystyrene boards is on the same plane, which solves the problem of polystyrene boards due to uneven outer surfaces and broken gaps. There is a problem of water seepage.

Description

(1) Technical field [0001] The invention relates to a construction process of an external heat-insulating layer of a wall. (2) Background technology [0002] For a long time, building walls were built with clay-fired red bricks, which were very popular and practical in a certain period. With the rapid development of my country's construction industry, people pay more and more attention to the thermal insulation performance of building walls, heating in winter, and saving the construction industry. Saving energy and improving building thermal conditions have become an urgent need for the construction industry and the entire society, especially It is an energy-saving building exterior wall insulation structure with high efficiency and energy saving that is being widely promoted and applied. At present, the thermal insulation structure of energy-saving building exterior walls mainly has three structural forms: internal thermal insulation, sandwich wall and external thermal insu...
