Description

Technical Field

[0001] The present invention relates to the technical field of low-carbon, energy-saving and environmentally friendly enclosure material preparation, and in particular to a preparation method of a photovoltaic thermal insulation assembled wall building block and the wall building block. Background Art

[0002] According to statistics, carbon emissions from buildings account for about 50% of the total carbon emissions. And building operations consume about 30% of the total energy consumption in the building sector. Therefore, "increasing revenue and reducing expenditure" in buildings is the most basic and easiest way to solve the carbon emission problem. It is also the method with the largest carbon reduction, the best input-output and the most economical method.

[0003] One of the key factors affecting the promotion and implementation of zero-energy buildings is the assembly of new ultra-low zero-energy energy-saving and thermal insulation building envelope material blocks and photovoltaic modules that utilize solar energy to form a multifunctional assembled unit module with enclosure structure, thermal insulation, power generation and decoration, and can realize the industrialized production of unit modules. Industrialized production is not only reflected in standardized assembly line production in the factory, but also more importantly in the standardization of design and intelligent manufacturing of construction.

[0004] Traditional wall power generation is a photovoltaic curtain wall system, such as CN202220069505.3, a green and energy-saving photovoltaic curtain wall. Since the photovoltaic curtain wall is attached to the building through a steel keel system, it is necessary to first embed and reserve the system installation components during the civil structure construction, and then complete the exterior wall insulation project of the building, or the interior wall insulation project. After the insulation project is accepted, the curtain wall steel structure project is made, and the fixed keel frame and the embedded parts on the structure are firmly connected and installed by bolts or welding, and finally the solar photovoltaic modules are installed; the entire curtain wall construction process is highly professional, requires professional qualifications and has a high cost.

[0005] The existing photovoltaic building integration is a combination of photovoltaic and architecture, which is completed through step-by-step construction; the photovoltaic roof construction is: first the structure is leveled, waterproofing works are done, then the insulation works and concrete pressing works are done, and after acceptance, the steel structure works are manufactured, and finally the photovoltaic modules can be installed on the steel structure. For example, the current wall construction steps are: first the masonry works are completed, then the wall leveling works are constructed, then the exterior wall insulation works are constructed, and then after the finishing works are completed, the curtain wall steel structure works are constructed and installed, and finally the photovoltaic power generation system is installed on the steel structure. The process is complicated, the amount of construction waste is large, the labor intensity is high, and the construction period is long.

[0006] At present, the composite structure of self-insulating blocks is formed by placing the insulation core material into a solid cement prefabricated block with a cavity. The solid cement prefabricated block with a cavity is made of cementitious materials, coarse and fine aggregates, water and other additives in an appropriate proportion, and is formed by pressing and molding through a steel mold using the vibration of a press to form a cement block with a cavity reserved for filling the insulation core material. After the water block hardens, the insulation core material is inserted into the cavity. The physical gap between the two is large, and a tight structure cannot be formed. There are many thermal bridges, and the masonry mortar is prone to cracking and water seepage. There is also a mold casting method, which places the core material into a pre-assembled mold, pours the slurry in the gap between the core material and the mold, and after the slurry solidifies, removes the mold and takes the product out of the mold. This production process has a low degree of industrial mass production, requires a huge number of molds, is easy to damage, and has a high scrap rate, so the cost is high.

[0007] Therefore, a method for preparing a multifunctional assembled unit module with enclosure structure, insulation, power generation and decoration, and realizing industrialized production of the unit module, needs to be completed on site in steps to meet the required comprehensive building functions, and it is difficult to realize the new business model of intelligent manufacturing of buildings. Summary of the invention

[0008] The purpose of the invention is to provide a method for preparing photovoltaic thermal insulation prefabricated wall blocks and wall blocks, which solves the problem of preparing a multifunctional prefabricated unit module with enclosure structure, insulation, power generation and decoration, and realizing the method of industrialized production of unit modules. It needs to be completed in steps on site to meet the required comprehensive building functions, and it is difficult to realize the new business model of intelligent manufacturing of buildings.

[0009] The present invention is achieved by a method for preparing a photovoltaic thermal insulation assembled wall block, the method comprising the following steps:

[0010] Step 1: Prepare a thermal insulation core material piece with a thermal insulation core material raw material, wherein the thermal insulation core material piece comprises a first accommodation space and a second accommodation space, wherein the first accommodation space is in the shape of a Chinese character “U”, and the second accommodation space is in an arc shape and is disposed inside the first accommodation space;

[0011] Step 2: placing the photovoltaic assembly into the first accommodation space, and performing grouting in the first accommodation space and the second accommodation space while avoiding the photovoltaic assembly, wherein the grouting layer forms a closed annular enclosure structure, and the photovoltaic assembly is fixedly connected to the enclosure structure;

[0012] Step 3, removing the insulation core material around the outer periphery of the enclosure structure to obtain a semi-finished product;

[0013] Step 4: Process the outer periphery of the semi-finished product to form tenons and mortises for upper and lower or / and left and right connections to obtain wall blocks.

[0014] The thermal insulation core material can not only be used as the thermal insulation core material, but also can act as a mold after being processed into the form of the first accommodating space and the second accommodating space in the present invention. Photovoltaic components are arranged in the first accommodating space to realize the function of power generation. After grouting, a protective structure with a protective function is formed. Considering that power generation requires heat dissipation and line shuttling, the second accommodating space is arc-shaped. After removing the thermal insulation core material on the periphery of the protective structure, a channel for heat dissipation and line shuttling can be formed. The multifunctional assembled unit module with protective structure, insulation, power generation and decoration obtained by the preparation method of the present invention does not require on-site assembly of multiple modules, can well meet the comprehensive functions of the building and realize intelligent manufacturing of the building.

[0015] A further technical solution of the present invention is: grouting is performed without using the first accommodation space for placing the photovoltaic components, and after obtaining the semi-finished product, the photovoltaic components are fixed to the outer facade of the enclosure structure by fixing parts.

[0016] A further technical solution of the present invention is: in the step 1, the thermal insulation core material raw material is used to form the thermal insulation core material piece on a molding device.

[0017] A further technical solution of the present invention is: the step 2 further includes placing a grid bracket in the second accommodating space.

[0018] The grid bracket is placed on a side of the second accommodating space away from the photovoltaic assembly, and a position for grouting is left in the second accommodating space, so that the enclosure structure is located between the grid bracket and the photovoltaic assembly.

[0019] A further technical solution of the present invention is that the grid bracket is a metal grid insert bracket; a wave-shaped die is used to punch the flat metal grid into a wave-shaped metal grid, and a bolt matrix is ​​welded on the grid.

[0020] A further technical solution of the present invention is: both ends of the second accommodating space are connected to the first accommodating space, both ends of the photovoltaic component with a matrix hole structure are connected to the bolts on the grid bracket through stainless steel screws, the photovoltaic component is placed in the first accommodating space, and the grid bracket is placed in the second accommodating space.

[0021] A further technical solution of the present invention is: a grid bracket is arranged in the second accommodating space, and after the semi-finished product is made or the step four is completed, the photovoltaic components are installed on the facade of the enclosure structure and connected to the bolts on the grid bracket by screws.

[0022] A further technical solution of the present invention is: in step three, the thermal insulation core material between the enclosure structure and the photovoltaic module is removed to form an arc-shaped channel.

[0023] The arc-shaped channel is used for heat dissipation of photovoltaic components and connection of circuits.

[0024] The thermal insulation core material removed from the periphery of the enclosure structure in the step three includes the thermal insulation core material between the enclosure structure and the photovoltaic module, and the thermal insulation core material on the outside of the photovoltaic module and the other three exterior surfaces of the enclosure structure. The thermal insulation core material between the enclosure structure and the photovoltaic module is arc-shaped or wavy on one side close to the enclosure structure.

[0025] A further technical solution of the present invention is that the outer facade of the semi-finished enclosure structure is corrugated, the crests are located at the fixed connection between the photovoltaic module and the thermal insulation core material, and an arc channel is formed between the troughs and the photovoltaic module.

[0026] There are multiple second accommodating spaces that are connected to form a corrugated shape. The outer facade of the enclosure structure formed after grouting is corrugated, and the crest of the wave is located at the fixed connection between the photovoltaic component and the thermal insulation core material. The connection points between the photovoltaic component and the thermal insulation core material are increased, thereby enhancing the connection stability between the photovoltaic component and the thermal insulation core material.

[0027] A further technical solution of the present invention is: in the step four, the enclosure structure and the thermal insulation core material on the bottom surface of the semi-finished product are processed to form a first mortise, and the enclosure structure on the top surface of the semi-finished product is processed to form a first tenon that cooperates with the first mortise.

[0028] When the blocks are assembled, the first mortise of the block is connected with the first tenon and mortise of another block, and the thermal insulation core material is tightly fitted in the vertical direction, so the thermal insulation effect is good.

[0029] The bottom protective structure and the thermal insulation core material of the semi-finished product are cut on the bottom surface by means of engraving, milling and thermal cutting equipment to form a first mortise that is recessed inwards; the protective structure is cut on the top surface of the semi-finished product by means of engraving, milling and thermal cutting equipment so that the thermal insulation core material on the top of the semi-finished product extends out of the protective structure, and then is processed into a first tenon that cooperates with the first mortise.

[0030] A further technical solution of the present invention is that the enclosure structure between the first mortise holes forms a reinforcing rib.

[0031] A single building block includes a plurality of first mortise holes and correspondingly is also provided with a plurality of first tenons. During assembly, the connection is more stable, the force is more evenly distributed, and the service life is longer.

[0032] A further technical solution of the present invention is: in the step four, the enclosure structure on one side of the semi-finished product is processed to form a second mortise, and the enclosure structure on the other side of the semi-finished product is processed to form a second tenon that cooperates with the second mortise.

[0033] Mortise and tenon structures are provided on both sides, which is conducive to the stability of the wall after assembly.

[0034] A further technical solution of the present invention is: in the step four, the enclosure structure on one side of the semi-finished product is cut to form a third mortise connected to the protective core material, and the protective core material on the other side of the semi-finished product extends out of the enclosure structure, and the protective core material is processed to form a third tenon that cooperates with the third mortise.

[0035] The enclosure structure on one side of the semi-finished product is cut to form a third mortise connected to the protective core material, and the third mortise is U-shaped; when the left and right blocks are connected, the third mortise and the third tenon cooperate with each other to make the thermal insulation core material fit in the horizontal direction, and the thermal insulation performance is better.

[0036] The present invention also provides a photovoltaic thermal insulation assembled wall building block, and the wall building block is obtained by the above-mentioned preparation method.

[0037] Beneficial effects of the present invention: the thermal insulation core material of the present invention can not only be used as a thermal insulation core material, but also can be processed into a form with a first accommodating space and a second accommodating space in the present invention, and can also play the role of a mold. The photovoltaic assembly is arranged in the first accommodating space to realize the function of power generation. After grouting, a protective structure with a protective function is formed. Considering that power generation requires heat dissipation and line shuttling, the second accommodating space is arc-shaped. After removing the thermal insulation core material on the periphery of the protective structure, a channel for heat dissipation and line shuttling can be formed. The multifunctional assembled unit module with a protective structure, heat preservation, power generation and decoration obtained by the preparation method of the present invention does not require on-site assembly between multiple modules, can well meet the comprehensive functions of the building and can realize intelligent manufacturing of the building;

[0038] The present invention formulates a high-fluidity slurry through specific research and development of high-performance concrete. The plasticity of the slurry is utilized, and through innovative molding technology, the thermal insulation core material is wrapped. After a certain curing process, an ultra-high-strength enclosure structure is formed after hydration. In particular, the micro-shrinkage characteristic of solidification can firmly wrap the thermal insulation core material inside to achieve seamless bite. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] The grid bracket is placed on a side of the second accommodating space away from the photovoltaic assembly, and a position for grouting is left in the second accommodating space, so that the enclosure structure is located between the grid bracket and the photovoltaic assembly.

[0069] In this embodiment, the grid bracket is a metal grid insert bracket; a flat metal grid is punched into a wavy metal grid using a wavy die, and a bolt matrix is ​​welded on the grid.

[0070] In this embodiment, both ends of the second accommodating space are connected to the first accommodating space, and both ends of the photovoltaic component with a matrix hole structure are connected to the bolts on the grid bracket through stainless steel screws. The photovoltaic component is placed in the first accommodating space, and the grid bracket is placed in the second accommodating space.
