Description

Technical Field

[0001] The present invention relates to the technical field of building components, and particularly to a foamed ceramic prefabricated exterior wall and an installation method thereof. Background Art

[0002] In recent years, prefabricated buildings and industrial modernization have developed rapidly in China. The State Council has issued the "Guiding Opinions on Vigorously Developing Prefabricated Buildings", further clarifying that in the future, green buildings and building materials should be actively promoted, and it is hoped that the proportion of prefabricated buildings in newly built buildings will reach 30% in about 10 years. The advantages of prefabricated buildings are fast construction speed, little restriction by climate conditions, labor saving and improved building quality.

[0003] The common existing method for exterior walls is to build hollow bricks and then construct a thermal insulation layer on the exterior wall surface. Its waterproof, sound insulation, energy saving and other performances are not ideal, the practicability is poor, and the on-site construction process is rather cumbersome and complex, with slow construction progress and long construction period.

[0004] The existing prefabricated lath exterior walls are difficult in joint treatment, with cumbersome processes and large quality fluctuations, making it difficult to ensure the watertightness of the exterior wall; and the architectural exterior decoration treatment is troublesome and cannot meet the high-quality aesthetic requirements; at the same time, there are also problems in energy-saving performance. The existing precast reinforced concrete exterior wall panels are relatively heavy in self-weight, making transportation and hoisting difficult and the construction measure costs expensive. Summary of the Invention

[0005] The purpose of the present invention is to provide a foamed ceramic prefabricated exterior wall and an installation method thereof, which have waterproof, fireproof and heat-insulating properties, low cost and fast construction.

[0010] Between any two adjacent decorative surface blocks 1, there is a caulking material 5 filled;

[0011] The decorative surface block 1 is made of foamed ceramic material and has a cubic shape; on the inner side of its top surface, there is a top protrusion 1-1, on the outer side of its bottom surface, there is a bottom protrusion 1-2, and a bottom groove 1-3 is arranged closely adjacent to the bottom protrusion 1-2 on the bottom surface; on the outer side of the decorative surface block 1, there is a decorative layer 1-4, and a caulking groove (1-5) is arranged along the side edge of the outer side of the decorative surface block 1;

[0012] The outer section of the stiffening rib 2-1 is provided with a curved protrusion 2-2 so that the cross-sectional shape of the stiffening rib 2-1 is a mallet shape; the middle part of the upper and lower surfaces of the stiffening rib 2-1 is provided with an intermediate protrusion 2-3 that matches the top protrusion 1-1 of the decorative surface block 1.

[0013] A method for installing a foamed ceramic assembled exterior wall is as follows: It comprises the following steps:

[0014] S1. The fixing base 4 is set on the outdoor side of the wall panel 3;

[0015] S2. The wall panel 3 is installed as a combination of the inner wall;

[0016] S3. The waterproof bonding layer 2 is fixed to the wall panel 3 through the fixing base 4;

[0017] S4. The decorative surface block 1 is inserted into the waterproof bonding layer 2 between the stiffening ribs 2-1;

[0018] S5. After the decorative surface blocks 1 are adjusted into place, the gap filling material 5 is placed in the gap between adjacent decorative surface blocks 1 .

[0019] Compared with the previous technology, the beneficial effects of the present invention are:

[0020] 1. The present invention adopts a waterproof bonding layer with both waterproof and surface layer fixing functions, which significantly improves the waterproof performance of the assembled exterior wall. Compared with conventional exterior wall waterproof structures, the construction speed is fast, the waterproof effect is reliable, and the cost is significantly reduced.

[0021] 2. The decorative effect of the decorative face blocks set in this prefabricated wall system is similar to that of traditional face bricks. The shape matching of the decorative face blocks and the waterproof bonding layer significantly increases the installation speed of the decorative face blocks compared with the traditional pasting process. At the same time, the seam width between the decorative face blocks can be accurately controlled, and the decorative effect is significantly improved.

[0022] 3. The decorative surface blocks and the waterproof bonding layer are mechanically engaged, and the caulking material is set on site, so that the integrity and durability of the finishing layer are significantly improved compared with the traditional pasting process.

[0023] 4. By setting decorative surface blocks on the outdoor side, the thermal insulation performance of the prefabricated wall can be improved, and the integration of thermal insulation and finishing can be achieved.

[0024] 5. As a new type of material, foamed ceramics have good moldability, light weight and high strength, fire resistance, heat preservation and durability, and have cost advantages in making building facades. BRIEF DESCRIPTION OF THE DRAWINGS
