A self-insulating anti-seismic block and its application method

Abstract

The invention belongs to the technical field of building materials, and relates to a building block. The building block comprises a longitudinal outer wall and a transverse outer wall which are enclosed to form a hollow thermal insulation cavity, and is characterized in that: the middle part of the longitudinal outer wall is provided with a reinforcing rib which protrudes towards the direction of the hollow thermal insulation cavity; the reinforcing rib and the longitudinal outer wall are enclosed together to form a middle grouting passage which is vertically run-through; the middle grouting passage is symmetrically arranged along a middle vertical plane of the longitudinal outer wall of the building block; and the outer end face of the transverse outer wall is provided with a vertical end face grouting groove. The building block has the characteristics of high self-thermal-insulation capacity, light deadweight, high strength and the like, and has a flat appearance, high integrity and high earthquake-proof capacity after being built; in addition, by matching with a method for building a vertical thermal insulation wall or a thermal insulation wall without mortar joints by applying the self-thermal-insulation earthquake-proof building block, the construction efficiency can be greatly increased, and easiness for standardization, high cost performance and high easiness for guaranteeing the construction quality are guaranteed. The building block can be widely applied to overall maintenance outside a building structure and a bearing structure of a low-rise building, and has extremely broad market prospect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a building block, in particular to a thermal insulation building block with high building efficiency and good overall performance. Background technique [0002] The exterior walls of buildings in our country mostly adopt masonry wall structure. The bricks traditionally used to build walls are mostly clay products, mainly made of benign clay. Due to the extensive use of benign clay, it will damage the cultivated land, and clay products generally have poor thermal insulation performance, high production costs, and pollution during the production process. environment and other disadvantages. Therefore, in recent years, fly ash bricks and various building blocks have begun to gradually replace traditional clay bricks in the market. However, there are still many problems in the application of existing bricks or blocks, mainly in the following aspects: [0003] (1) The prob...

AI Technical Summary

Problems solved by technology

At present, some masonry materials such as fly ash bricks are small in size, and the traditional "three one" bricklaying method of one shovel ash, one brick, and one squeeze is mostly used. The construction steps are cumbersome and the construction efficiency is low. There is no guarantee for the fullness of the mortar joints, and the construction quality largely depends on the proficiency level of the workers. With the increase of labor costs, the cost of masonry will also increase;

[0004] (2) Strength problem

After replacing clay bricks with fly ash autoclaved materials, energy consumption is reduced and clay resources are saved, but the spherical particle shape of fly ash affects the bonding strength between fly ash autoclaved materials and masonry mortar. As a result, the overall strength of the masonry wall is not high, which affects the earthquake resistance of the building

In addition, the existing hollow blocks and aerated concrete blocks have low self-strength, which affects the ability of the wall to hold nails and hang heavy objects;

[0005] (3) Insulation problem

However, most of the current insulation methods are polystyrene board external wall insulation systems, which have problems such as fire hazards and the short life of the building's external wall insulation, which cannot last the same life as the building.

Now some people use hollow blocks, and then fill the cavity of the blocks with insulation materials to achieve wall insulation, but because the ribs and mortar joints of these blocks will form cold and heat bridges during use, thus affecting The overall thermal insulation performance, the thermal insulation coefficient is not high;

[0006] (4) Cracking and permeable problems

Due to the common existence of the mortar joint structure through the wall in the existing masonry structure, in the long-term use process, once cracks appear between the block and the mortar joint, due to the existence of cracks, the gap between the masonry block and the mortar is not dense and other reasons, leading to water seepage problems in the outer walls of buildings

[0007] To sum up, the existing bricks and blocks cannot fully meet the needs of masonry wall structures, and the market urgently needs new blocks with better performance to solve the above problems
