Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a composite self-insulating building block based on EPS foam concrete. Background Art

[0002] Traditional building energy conservation mainly adopts three types of thermal insulation systems, namely, external wall insulation system, internal wall insulation system and composite insulation system. However, the current non-load-bearing wall self-insulating blocks are difficult to meet the actual production needs in design, which is mainly reflected in the following aspects: the existing blocks lack effective thermal insulation performance and cannot provide ideal thermal insulation effect. Some manufacturers have made technical improvements on this basis and achieved certain results by improving thermal insulation effect and weight reduction design, but there is still room for further optimization and improvement.

[0003] At present, in order to solve the deficiencies in the existing technology, a composite self-insulating building block based on EPS foam concrete is designed to reduce weight and improve thermal insulation performance by simplifying and optimizing the overall structure. The design aims to make the building block have higher thermal insulation effect and lighter weight through reasonable material configuration and structural improvement to meet practical application needs. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide a composite self-insulating building block based on EPS foam concrete. The building block adopts an integrally formed EPS foam concrete structure, including through holes, protrusions and grooves, to overcome the shortcomings of existing hollow bricks in terms of thermal insulation performance. By filling insulation materials on both sides, the heat source transfer is effectively blocked, the thermal insulation performance of the building block is further optimized, and its weight is reasonably reduced to achieve better insulation and weight reduction effects.

[0005] To achieve the above purpose, a self-insulating composite building block is provided, which includes a base body integrally formed by using EPS foam concrete, and the base body is provided with a through hole, a protrusion and a groove. The through hole extends along the height direction of the base body and longitudinally penetrates the upper and lower surfaces of the base body, and the two through holes are respectively located on both sides of the center in the width direction of the base body; first grooves are provided on both sides of the base body, and the first grooves extend along the height direction and longitudinally penetrate the upper and lower surfaces of the base body, and the first grooves are filled with thermal insulation materials to enhance the thermal insulation performance of the building block.

[0006] The block base (1) is made of EPS foam concrete, which has excellent thermal insulation performance and certain strength, and can meet the use requirements of self-insulating blocks. The side surface is provided with four positioning protrusions (3) and four second grooves (6), which are distributed in a rectangular array on the side surface of the block body. The protrusion (3) is in the shape of a triangle, and is designed to be precisely matched with the second groove (6), so as to achieve stable connection of the block.

[0007] The positioning protrusions on the block body have the same size, and the positioning grooves have the same size.

[0008] The air-insulating and weight-reducing holes are arranged as long strip holes, and there are two of them in total.

[0009] The outermost rows of grooves at both ends in the width direction of the substrate are filled with XPS thermal insulation material.

[0010] The utility model adopts an integrated EPS foam concrete structure, including through holes, protrusions and grooves, and uses desert sand instead of traditional sandstone and cement mixed casting to achieve effective resource utilization and turn waste into treasure. The through hole and the groove design filled with thermal insulation material can not only reduce the weight of the block and reduce the production cost, but also help to cut off the heat conduction path, thereby significantly improving the thermal insulation effect of the block;

[0011] The utility model is suitable for supporting use with local building materials.

[0017] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the utility model will be described in detail below in conjunction with the drawings of specific embodiments of the utility model.

[0018] Reference Figure 1 and Figure 2 The utility model realizes a self-insulating composite building block. The building block includes an integrally formed EPS foam concrete building block base 1, on which a through hole 5, a protrusion 3, a first groove 2 and a second groove 6 are provided. The through hole 5 extends along the height direction of the building block base 1 and longitudinally penetrates the upper and lower surfaces of the base 1. A total of two through holes 5 are provided, distributed on both sides of the width center; the first groove 2 also extends along the height direction of the base, and longitudinally penetrates the upper and lower surfaces of the building block base 1, and is distributed on both sides of the building block base 1; in addition, the first grooves 2 on both sides of the building block base 1 are filled with thermal insulation materials 4 to enhance the thermal insulation performance.

[0019] The middle part of the block base 1 of the utility model is provided with two through-designed weight-reducing holes 5. This structure not only effectively reduces the weight of the block, but also can isolate the inside and outside air, reduce the conduction of cold air, and thus improve the thermal insulation performance.

[0020] The insulation material 4 filled on the side of the block is XPS polystyrene insulation material. The material is made of polystyrene resin as the main raw material, with auxiliary materials and polymers added, and extruded after heating and mixing and injecting catalyst. XPS insulation material has extremely low water absorption, low thermal conductivity, high compressive resistance and aging resistance, and also has high thermal resistance, low linearity and low expansion rate. Its closed porosity exceeds 99%, forming a vacuum layer, effectively preventing air flow and heat dissipation, and ensuring long-lasting and stable insulation performance.

[0021] The two first grooves (2) have the same thickness, and the two through holes (5) have the same thickness.

[0022] Furthermore, the protrusion 3 and the second groove 6 have the functions of positioning and auxiliary connection, and are triangular in design when viewed from the front. The protrusion 3 is engaged with the groove 6 of the adjacent building block to achieve a stable connection between two adjacent building block bodies 1 in the horizontal direction.

[0023] Working principle: When the self-insulating composite building block is used, the adjacent building block bodies 1 are firmly connected in the horizontal direction by the engagement of the protrusions 3 and the grooves 6. The design of the through holes 5 and the insulation material 4 gives the building block body 1 a good insulation effect, thereby ensuring that the entire self-insulating composite building block has excellent insulation performance.

[0024] The above description is only a preferred specific implementation mode of the present invention. For those skilled in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
