An anti-strike structure suitable for the exterior wall of a prefabricated building

Abstract

The invention provides an anti-beating structure suitable for the outer wall of a prefabricated building, which includes a thermal insulation board, a cover layer and an L-shaped embedded part. The L-shaped embedded parts include the intersecting inner arm and outer arm. The length of the outer arm is greater than the thickness of the insulation board. The outer arm is perpendicular to the thickness direction of the insulation board. It is close to the outer wall of the cover layer and connected to the inner arm. One end is facing the inner side of the insulation board, and the free end of the inner arm is facing the center of the insulation board. The insulation board, the cover layer and the L-shaped embedded part are connected as a whole through the connecting piece pierced by the L-shaped embedded part. The insulation board includes 100 parts of inorganic fiber and 1-13 parts of phenolic resin. The present invention proceeds from the two aspects of structural design and research and development of new fire-proof and heat-preservation materials. Through reasonable structure layout, the structure of the anti-beating structure is simple, and the outer wall is convenient to process. Combined with new heat-preservation materials, it greatly improves fire prevention, isolation, and tensile strength. pull performance.

Description

technical field [0001] The invention belongs to the field of new prefabricated buildings, in particular to an anti-strike structure suitable for the outer walls of prefabricated buildings. Background technique [0002] With the development of the construction industry, new prefabricated buildings have become a building form vigorously promoted by the state due to factory-like customized production, which effectively guarantees product quality and avoids potential safety hazards caused by human factors in on-site construction. At present, the anti-beating structures commonly used in building walls in the market are mostly sandwich structures of traditional organic thermal insulation materials, or rock wool external structures. Although each has its own advantages, its disadvantages are also very obvious.

AI Technical Summary

Problems solved by technology

At present, most of the anti-beating structures for building walls in the market are sandwich structures of traditional organic thermal insulation materials, or rock wool external structures. Although each has its own advantages, its disadvantages are also very obvious.

The sandwich structure made of organic thermal insulation materials, the upper and lower layers are poured with cement, and the core layer is made of organic thermal insulation materials. Due to the characteristics of organic thermal insulation materials, the service life of the materials is much shorter than that of cement materials. After more than ten years of use, the materials will inevitably age. The core material becomes a hollow wall, which brings safety hazards to life and property

Due to the low strength of the rock wool material, calcium silicate boards need to be used on the top and perforated cement boards on the bottom to form a sandwich structure, which increases the complexity and cost of construction.
