Description

Technical Field

[0001] This utility model relates to a GRPS concrete composite block, belonging to the field of building material production technology. Background Technology

[0002] Concrete composite blocks are a type of block made by combining concrete as the base material with high-efficiency thermal insulation materials or other functional materials through a specific process. Their core feature is the integration of structural performance with functions such as thermal insulation and sound insulation through material composites, reducing the need for secondary insulation treatment during construction.

[0003] A search revealed a utility model patent with patent number 202320469873.1, which discloses a self-insulating concrete composite block. It comprises: a main block, a Class A fireproof insulation layer, and a crack-resistant protective layer. The Class A fireproof insulation layer is located between the main block and the crack-resistant protective layer, and is connected to the main block using a dovetail groove nesting method. A connecting piece penetrates the Class A fireproof insulation layer and extends into the main block. This block has a simple structure and low cost.

[0004] While the aforementioned patents can meet basic insulation requirements, they have the following drawbacks: 1. The construction of composite blocks depends on the skill level of the construction workers, which can easily lead to misalignment between adjacent composite blocks, affecting the quality of the masonry project. 2. Traditional concrete composite blocks often use a single insulation material (such as EPS, XPS, or rock wool) as the core material, which lacks excellent weather resistance, durability, and dimensional stability. They also lack the lightweight and easy-to-construct characteristics of polystyrene, and their performance directly affects the building's thermal insulation effect, fire safety, and construction efficiency.

[0005] To solve one of the above problems, there is an urgent need for a GRPS concrete composite block. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to achieve the formation of positioning protrusions and end positioning grooves in the assembled GRPS concrete composite blocks to form a firm protrusion-groove snap-fit. To this end, a GRPS concrete composite block is provided.

[0007] The GRPS concrete composite block of this utility model has an end positioning groove at one end and a positioning protrusion at the other end that cooperates with the adjacent end positioning groove. Its features include: concrete block bodies C and D arranged parallel to each other and spaced apart; the concrete block bodies C and D are located on both sides of a central wall block; the central wall block is staggered with the concrete block bodies C and D; the central wall block includes concrete block bodies A and B spliced ​​end to end; a dovetail groove A is provided on the concrete block body C; overlapping protrusions A and B are respectively provided on the concrete block bodies A and B; the overlapping protrusions A and B are spliced ​​to form a dovetail block A that cooperates with the dovetail groove A; the concrete block body A includes an insulation layer A; an outer concrete layer A and an inner concrete layer A are respectively provided on both sides of the insulation layer A; the outer concrete layer A and the overlapping protrusion A are integrally formed; and the insulation layer A is a GRPS insulation board.

[0008] GRPS insulation board is a rigid foam plastic board with micro-closed-cell structure and high performance, made by mixing polystyrene resin and its copolymers as the main components, mixing a certain amount of graphite and nano-additives, mixing under high temperature and high pressure, injecting fluid foaming agent, and pressing and extruding.

[0009] GRPS concrete composite blocks, made from GRPS insulation boards, possess excellent weather resistance, durability, and dimensional stability due to the micro-closed-cell structure of the GRPS insulation boards combined with a compression extrusion process. They are suitable for harsh environments and retain the lightweight and easy-to-construct characteristics of polystyrene, making them suitable for ultra-low energy consumption buildings.

[0010] The concrete block body A, concrete block body B, concrete block body C and concrete block body D are modular structures that can be prefabricated in the factory and then assembled and connected on the construction site using newly added dovetail grooves and dovetail blocks. The assembled GRPS concrete composite blocks form positioning protrusions and end positioning grooves, forming a firm protrusion-groove snap-fit, reducing on-site cutting losses, and standardizing production to reduce waste of scrap materials.

The overlapping protrusions C are integrally formed with the inner concrete layer A, and the overlapping protrusions C and D are spliced ​​to form a dovetail block C that matches the dovetail groove C. This enhances the reliability of the connection.

[0012] Preferably, dovetail blocks B are provided on both sides of the insulation layer A, and dovetail grooves B that mate with the corresponding dovetail blocks B are provided on the outer concrete layer A and the inner concrete layer A, respectively.

The inner side of the concrete block body D has an inner side plate B, and the end of the inner side plate B has an inner side plate B. The side wall of the insulation layer B has a tail positioning groove that mates with the bend A and the inner side plate B. The tail positioning groove is arranged along the vertical direction of the concrete block body B. This forms a firm protrusion-groove interlocking connection.

[0017] Preferably, the inner side plate A is integrally formed with the concrete block body C, and the inner side plate B is integrally formed with the concrete block body D.
