Embodiment Construction

[0024] The technical solutions of the present invention will be further illustrated and described below through specific embodiments in conjunction with the accompanying drawings.

[0025] A method for treating anti-cracking joints of light-weight thermal insulation slat walls, the steps are as follows:

[0026] (1) Select a flat installation surface, and coat the contact between the two lightweight slats 1 with polymer mortar 2. The polymer mortar 2 includes cement, fine sand, EVA rubber powder, PVA, cellulose ether, powder Coal ash, mineral powder and water, the weight ratio of the above components is 100: (100-400): (0-10): (0-4): (0-4): (8-14): (6- 16): (40-65);

[0027] (2) Use the lower wedge roof method to install the strip 1, so that the joint is filled with polymer mortar 2, and scrape the joint with a scraper;

[0028] (3) if figure 1 As shown, draw a line 20 mm along the two ends of the center of the above-mentioned joint, and apply the adhesive 3 symmetrically a...

Abstract

The invention discloses a light insulation batten wall body anti-cracking joint treatment method which comprises the following steps of (1) coating polymer mortar on a contact face between battens; (2) installing the battens by utilizing a low wedge roof method, enabling the polymer mortar to be squeezed at the joint position between the battens, and using a scraper to scrape the joint position; and (3) adhering two lateral edges of an elastic cover sheet on two sides of the joint position from top to bottom, and completely covering the elastic cover sheet on the joint position. According to the light insulation batten wall body anti-cracking joint treatment method, the rubber sheet is symmetrically adhered to the joint position of the battens, the technical problem that a joint of a light insulation batten wall body is easy to crack is effectively solved, and installation quality of the battens is ensured.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a treatment method for anti-cracking joints of light-weight thermal insulation slab walls. Background technique [0002] Lightweight insulation slats have the advantages of light weight, sound insulation, heat preservation, simple process, convenient construction, good safety performance, easy maintenance and transformation, and utilization of industrial waste, energy saving and waste utilization, etc. It is an ideal material to replace traditional clay bricks. However, cracks are prone to appear in the light insulation batten wall after a period of time of construction. The cracks usually appear at the joints, and most of them are vertical cracks along the interface between the lightweight batten and the polymer mortar. The main reason for the cracks is the dry shrinkage and cold shrinkage of the thermal insulation mortar. When the shrinkage of the light insul...
