A modular porous brick with an inner and outer double-layer structure

Abstract

This utility model discloses a modular porous brick with an inner and outer double-layer structure, comprising a first brick with multiple limiting grooves inside, a second brick outside the first brick, multiple locking blocks fixedly connected inside the second brick, and continuous graded aggregate fixedly connected to the bottom of the first brick. Through this structure, the multiple limiting grooves inside the first brick allow the locking blocks on the outside of the second brick to connect with the limiting grooves, thereby splicing the first and second bricks. This results in uniform gaps after splicing, facilitating mortar filling, enhancing the integrity and sealing of the wall, and reducing the risk of leakage. The continuous graded aggregate inside the first brick reduces internal voids, increases density and compressive strength, and the layer of lightweight aggregate inside the continuous graded aggregate reduces brick density while enhancing thermal insulation performance, meeting energy-saving requirements.

Description

Technical Field

[0001] This utility model relates to the field of modular porous brick technology, and in particular to a modular porous brick with an inner and outer double-layer structure. Background Technology

[0002] Modular porous bricks refer to porous bricks that meet the building module requirements, with a porosity of not less than 15%, and the pores can be round or non-round. Some modular porous bricks may have a pore distribution similar to a double-layer structure. For example, a modular porous brick in one patent has a large through-hole at the center of its length × width surface, surrounded by several small through-holes arranged in a row. The large through-hole is used for centralized heat dissipation and absorption, while the small through-holes around the perimeter are used for heat insulation, energy saving, and earthquake resistance. This pore distribution can, to some extent, achieve a similar effect to a double-layer structure.

[0003] However, some installations are difficult to adapt to different wall sizes during construction. Cutting bricks can damage the double-layer structure and porous design, further weakening the wall's stability. The inability to splice bricks results in ineffective interlocking, significantly reducing the wall's overall integrity and making it prone to gaps, delamination, and increased voids between aggregate particles. This leads to a loose and unstable skeletal structure, making it more susceptible to failure under pressure. Furthermore, larger voids require more cement grout to fill; if the amount of cement grout remains constant, the water-cement ratio increases, leading to increased porosity and reduced strength after the bricks harden. Utility Model Content

[0004] The purpose of this utility model is to provide a modular porous brick with an inner and outer double-layer structure, which solves the problem that the lack of effective splicing will reduce the overall integrity of the wall, weaken its crack resistance and earthquake resistance, and require the addition of reinforcement components.

[0006] According to the present invention, a modular porous brick with an inner and outer double-layer structure is provided, wherein an air-entraining agent is fixedly connected to the bottom of the high-efficiency water-reducing agent.

[0007] According to the present invention, a modular porous brick with an inner and outer double-layer structure is provided, wherein a mineral admixture is fixedly connected to the bottom of the air-entraining agent.

[0008] Beneficial effects 1. The present technical solution provides a modular porous brick with an inner and outer double-layer structure.
