Description

Technical Field

[0001] This utility model relates to the field of building exterior wall insulation systems, specifically to a homogeneous composite sandwich self-insulating block. Background Technology

[0002] In recent years, driven by the "dual carbon" goals and guided by the green development strategy, my country's construction industry urgently needs to break through the energy-saving and safety bottlenecks of traditional building materials. The application and promotion of homogeneous self-insulating blocks as infill wall materials is an important technological innovation in this context. With the implementation of the new version of the "General Specification for Building Energy Conservation and Renewable Energy Utilization," the building energy efficiency rate has increased to over 75%. Its Class A fire resistance and lifespan comparable to that of the building align with the needs of building industrialization and the standardization of prefabricated buildings, and have received policy support. Furthermore, by utilizing industrial solid waste such as fly ash to reduce environmental impact, this technology is gradually becoming a core solution for achieving low-carbon transformation and improving the comprehensive benefits throughout the entire life cycle of buildings.

[0003] The currently widely used homogeneous sandwich insulation blocks are connected only by the dovetail groove of the insulation core material and the concrete of the block. This results in insufficient confinement of the insulation core material by the concrete, and the insulation core material and the concrete of the insulation block are separated into two layers. This makes the sandwich insulation block structure unstable. In addition, many self-insulating blocks have problems such as easy shrinkage, cracking and high water absorption, which affect the thermal insulation performance of the exterior walls of prefabricated buildings. Utility Model Content

[0004] The purpose of this invention is to provide a homogeneous composite sandwich self-insulating block to solve the problems existing in the prior art, improve the limitation of thermal expansion of the core material, prevent uneven deformation from causing wall cracks, and enable the self-insulating block to have a stable structure and thermal insulation and fireproof performance.

[0005] To achieve its purpose, this utility model adopts the following technical solution:

[0006] A homogeneous composite sandwich self-insulating block includes: a self-insulating block body, a lightweight concrete homogeneous structural layer, a thermal insulation homogeneous structural layer, and connectors.

[0007] The heat-insulating homogeneous structural layer is made of heat-insulating core material and is installed along the length of the self-insulating block body through connectors; the heat-insulating homogeneous structural layer has four chamfered corners or through holes;

[0008] The lightweight concrete homogeneous structure layer covers all parts of the thermal insulation homogeneous structure layer except for the exposed surfaces at both ends that need to ensure thermal insulation continuity, as well as the connectors. The lightweight concrete homogeneous structure layer is made of cement polystyrene particle microporous concrete.

[0009] As a further improvement to the technical solution of this utility model, the lightweight concrete homogeneous structure layer is provided with reinforcing ribs that are adapted to the four-sided chamfered corners or through holes of the thermal insulation homogeneous structure layer. The reinforcing ribs connect the lightweight concrete on both sides of the thermal insulation homogeneous structure layer together and solidify it into an integral box-shaped structural block.

[0010] Furthermore, the self-insulating block body is provided with anti-shear grooves at both ends and four corners.

[0011] Furthermore, the insulation core material is polystyrene board or rock wool board.

[0012] Furthermore, the connector is classified into Type I connector, Type II connector, or GRP connector.

[0013] Furthermore, after the connector penetrates the thermal insulation homogeneous structure layer, its two ends are connected to the lightweight concrete homogeneous structure layer.

[0014] Furthermore, the number of connectors is two for each self-insulating block body, and they are evenly arranged parallel to the self-insulating block body.

[0015] This utility model has the following beneficial effects:

[0016] 1. Traditional sandwich insulation blocks are connected to the block with concrete through tenon and groove joints of the insulation core material, which is prone to cracking and separation. This utility model uses corner cutting or drilling treatment on the four corners of the insulation core material, and then inserts one of three optional connectors. After pouring cement polystyrene particle microporous concrete, the lightweight concrete on both sides of the insulation core material is connected together to form a reinforcing rib. Moreover, the two ends of the connector are also anchored to the lightweight concrete on both sides of the insulation core material, making the connection between the insulation core material and the lightweight concrete on both sides reliable and firm. This improves the limitation of thermal expansion of the core material, ensures the volume stability of the product, and solves the problem of separation and cracking of the core material and the concrete of the product during the construction of traditional insulation blocks.

[0017] 2. The two ends of the block of this utility model are designed with anti-shear grooves. During the construction, the anti-shear grooves are filled with masonry mortar. After the block is formed into a wall, the overall stability of the structure can be improved, so that the durability of the homogeneous composite sandwich self-insulating block can meet the technical requirements of the same lifespan as the main building structure.

[0018] 3. This utility model of homogeneous composite sandwich self-insulating block uses cement polystyrene particle microporous concrete for pouring, realizing the inorganic material covering the insulation material. The exposed core material at both ends of the block ensures the continuity of the insulation layer between the blocks, which can effectively block thermal bridges and maintain the stability of the wall temperature. After construction, the insulation block is not exposed to open flames and air on all six sides, forming a box-shaped small fireproof compartmentalized composite product, which can give the product high-efficiency insulation and fireproof performance.

[0019] 4. The cement-polystyrene particle microporous concrete used in this novel homogeneous composite sandwich self-insulating block is a composite lightweight material. Through the synergistic effect of the cement matrix with introduced foaming agent and the polystyrene particles, a uniform microporous structure is formed, possessing properties such as thermal insulation, lightweight high strength, sound insulation, and waterproofing. Specifically, the introduction of polystyrene particles significantly reduces the material density (≤600 kg / m³), reducing the wall's self-weight by approximately 30%-40%, thus reducing the building's structural load. Simultaneously, the closed microporous structure significantly reduces the thermal conductivity, resulting in superior thermal insulation performance compared to traditional aerated concrete, meeting building energy efficiency standards of over 75%. Furthermore, the high strength of the cement matrix combined with the elastic deformation capacity of the polystyrene particles enables the material's compressive strength to reach MU5.0 or higher, and the microporous structure effectively disperses stress, resulting in excellent crack resistance and seismic performance. In addition, the cement-encapsulated polystyrene particle process avoids the flammability defects of EPS, achieving Class A fire resistance standards, and through optimized proportioning, achieves low water absorption, preventing freeze-thaw damage and ensuring durability of over 50 years.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0029] Reference Figure 1-7 This utility model provides a homogeneous composite sandwich self-insulating block, comprising a self-insulating block body 1, a lightweight concrete homogeneous structural layer 2, an insulating homogeneous structural layer 3, and connectors. The insulating homogeneous structural layer 3 is made of insulating core material (polystyrene board or rock wool board) and is installed along the length of the self-insulating block body 1 via connectors. The connectors penetrate the insulating homogeneous structural layer 3, and their two ends are connected to the lightweight concrete homogeneous structural layer 2. The insulating homogeneous structural layer 3 has four chamfered corners or through holes. The lightweight concrete homogeneous structural layer 2 covers all parts of the insulating homogeneous structural layer 3 except for the exposed surfaces at both ends where insulation continuity needs to be ensured, as well as the connectors. The lightweight concrete homogeneous structural layer 2 is made of cement-polystyrene particle microporous concrete.

[0030] The self-insulating block body 1 of this utility model has four-sided corner cutting or perforation treatment of the set heat-insulating homogeneous structural layer 3, and is covered by a lightweight concrete homogeneous structural layer 2, which enhances the restriction of thermal expansion of the core material, ensures the volume stability of the self-insulating block body 1, prevents wall cracking caused by uneven deformation, and also improves the durability of the self-insulating block body 1, thus achieving the technical requirement that the self-insulating block body 1 has the same service life as the main building structure.

[0031] Among them, the lightweight concrete homogeneous structure layer 2 has reinforcing ribs 9 that are compatible with the corner cutting or drilling treatment of the thermal insulation homogeneous structure layer 3 or the thermal insulation homogeneous structure layer 4. The reinforcing ribs 9 connect the lightweight concrete on both sides of the thermal insulation homogeneous structure layer together and solidify it into an integral box-shaped structural block. Setting the reinforcing ribs 9 can improve the structural integrity of the thermal insulation panel 1.

[0032] Specifically, the self-insulating block body 1 has shear grooves 8 at both ends and four corners, i.e., mortar grooves. During construction, the shear grooves 8 are filled with mortar, and the mechanical interlocking between the blocks improves the overall shear resistance, thereby enhancing the structural performance without affecting the insulation performance. This improves the overall stability and safety of the wall structure after the self-insulating block body 1 is completed, ensuring the durability of the self-insulating block body 1.

[0033] To further enhance the connection between the thermal insulation homogeneous structural layer 3 and the lightweight concrete homogeneous structural layer 2, three optional special connectors are provided: Type I connector 5, Type II connector 6, or GRP connector 7. Any of these three connectors can be selected. After penetrating the thermal insulation homogeneous structural layer, the special connectors are anchored at both ends to the lightweight concrete homogeneous structural layer 2, solidifying into an integral box-shaped structural block. This enhances the connection strength between the thermal insulation homogeneous structural layer and the lightweight concrete homogeneous structural layers 2 on both sides, ensuring the overall structural strength and stability of the self-insulating block body 1.

[0034] In practical applications, the number of three optional connectors: Type I connector 5, Type II connector 6 or GRP connector 7 can be 2 per self-insulating block body 1, and they are arranged evenly in parallel along the self-insulating block body 1 to enhance the uniformity of stress on the homogeneous insulation layer 3, thereby improving the structural stability of the self-insulating block body 1.

[0035] In the production of the self-insulating block of this utility model, the heat-insulating homogeneous structural layer 3 is installed by connecting it with type I connectors 5, type II connectors 6 or GRP connectors 7, and then placed in the forming mold 11. The bottom mold of the forming mold 11 is welded with positioning steel bars 10. A pre-set gap is made between the heat-insulating homogeneous structural layer 3 and the inner wall of the forming mold 11. The well-mixed fluidized cement polystyrene particle microporous concrete is poured between the heat-insulating homogeneous structural layer 3 and the forming mold 11 to cover the heat-insulating homogeneous structural layer 3 and the connectors. Then it is cured. After the fluidized cement polystyrene particle microporous concrete hardens to form a lightweight concrete homogeneous structural layer 2, it is demolded and cured to obtain the finished product of homogeneous composite sandwich self-insulating block.

[0036] Furthermore, after connecting the heat-insulating homogeneous structural layer 3 with Type I connectors 5, Type II connectors 6, or GRP connectors 7, it is placed into the assembly molding mold 11 and fixed to the positioning steel bar 10. This further improves the stability of the heat-insulating homogeneous structural layer 3 during the pouring of fluidized cement polystyrene particle microporous concrete, providing a strong guarantee for the production of homogeneous composite sandwich self-insulating blocks. In practical applications, barbs can be provided on the positioning steel bar 10 to prevent the heat-insulating homogeneous structural layer 3 from floating during concrete pouring, further ensuring the stability of the heat-insulating structural layer during pouring.
