Description

Technical Field

[0001] The utility model relates to the field of composite walls, in particular to an assembled composite wall used for fire abandonment and wintering in high-latitude and cold regions. Background Art

[0002] In construction projects in high-latitude and cold regions, especially when designing and constructing fire-abandoned wintering facilities suitable for extreme climate conditions, it is crucial to choose a wall structure that can effectively insulate and resist the invasion of severe cold, adapt to local resource limitations, and be convenient to construct and easy to maintain. Although traditional composite walls meet the requirements of thermal insulation performance to a certain extent, they often have problems such as complex construction, difficulty in replacing a single unit after damage, and high overall maintenance costs.

[0003] The construction of traditional composite walls involves multiple processes and the integration of multiple materials, such as base masonry or frame construction, insulation material installation, moisture-proof layer laying, and finishing layer fixing. The process is cumbersome and requires high construction accuracy and workers' professional skills. Especially in high-altitude cold areas, harsh climatic conditions may limit the construction window, increase construction difficulty and time cost. In addition, the process of cutting, splicing and fixing different materials on site may lead to material waste and environmental pollution.

[0004] Once a layer or component in a composite wall is damaged, it is often impossible to partially remove and replace it due to the close physical connection between the layers of materials (such as bonding, anchoring, embedding, etc.), and a large area of ​​the wall needs to be repaired or even replaced as a whole. This "one move affects the whole body" characteristic not only increases the maintenance cost, but may also cause the interruption of building functions and affect the life or production activities of residents. Utility Model Content

[0005] The main purpose of the utility model is to provide an assembled composite wall for wintering in high-latitude and cold regions, so as to solve the problems that although traditional composite walls meet the requirements of thermal insulation performance to a certain extent, they often have the problems of complex construction, difficulty in replacing single units after damage, and high overall maintenance costs.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: an assembled composite wall for wintering in high-latitude and cold areas, including exterior wall panels, multiple second hangers are provided on the inner surface of the exterior wall panels, one side of the assembly net is hung on the second hangers of the exterior wall panels, the interior of the assembly net is provided with insulation material and moisture-proof material, and a first hanger is also provided, the first hanger is set on the wall, the other side of the assembly net is hung on the wall, and multiple exterior wall panels are overlapped to form an exterior wall surface.

[0007] In a preferred embodiment, an opening is provided above the assembly net, a plurality of holes are provided around the assembly net, and the plurality of holes on both sides of the assembly net are hung on the first hanging piece and the second hanging piece.

[0008] In a preferred embodiment, an outer lap plate is provided on one side of the exterior wall panel, and an inner lap plate matching the outer lap plate is provided on the other side of the exterior wall panel.

[0009] In a preferred embodiment, a composite rubber strip is provided on the inner surface of the outer lap plate or the inner lap plate.

[0010] In a preferred embodiment, after the plurality of assembly nets are assembled on the exterior wall panels, the surfaces of adjacent assembly nets are bonded to each other.

[0011] In the preferred embodiment, a plurality of cement nails are provided in the middle of the first hanging component, a through hole is provided at the lower end of the first hanging component, and a self-tapping screw is provided inside the through hole.

[0012] In the preferred embodiment, a main grouting hole is provided inside the self-tapping screw, and a plurality of test grouting holes are provided on the self-tapping screw, and the test grouting holes are connected to the main grouting holes.

[0013] In a preferred embodiment, the thermal insulation material is a rubber-plastic thermal insulation material, or an aluminum silicate thermal insulation material.

[0014] In a preferred embodiment, the moisture-proof material is a moisture-proof gypsum board or a moisture-proof particle board.

[0015] The utility model provides an assembled composite wall for fire-abandoning and wintering in high-latitude and cold regions, with an assembly net as a skeleton structure: the assembly net serves as a support and integration structure inside the wall, provides a stable mounting platform for thermal insulation materials and moisture-proof materials, and ensures the precise arrangement and positioning of these functional materials inside the wall. The design of the assembly net should have sufficient strength and durability to withstand loads and adapt to severe cold environments.

[0016] Modular installation of thermal insulation and moisture-proof materials: These two key functional materials are placed inside the assembly net and adopt a modular design, which can be independently manufactured, transported and installed on site. Modularity allows materials to be prefabricated into standard sizes in the factory to ensure quality control, and simplifies the on-site assembly process, avoiding material loss and environmental pollution caused by on-site cutting and splicing. At the same time, the modular design facilitates the replacement of single units within the wall's service life. When a module is damaged, there is no need for large-scale demolition and modification, and only the corresponding part needs to be replaced, which greatly reduces the maintenance cost and the impact on the normal use of the building.

[0017] Exterior wall panels overlap to form a flat facade: Exterior wall panels are directly installed on one side of the assembly net, and overlap each other to form a continuous and flat exterior wall. This design is conducive to enhancing the integrity and sealing of the building's appearance, reducing cold wind penetration and moisture intrusion. The overlap method should ensure the airtightness and watertightness of the joints, and special sealing strips or waterproof fasteners may be used.

[0018] The first hanging part realizes convenient connection with the wall: the assembly net is firmly hung on the existing wall surface through the first hanging part, without deep modification of the original wall. The hanging system should be designed to be easy to install, adjust and disassemble, adapt to different wall types and construction conditions, further simplify the construction process and shorten the construction period.

[0019] Overall construction advantages: This prefabricated composite wall system emphasizes the convenience of construction, reduces the complexity of on-site operations from the design, and significantly improves construction efficiency. Standardized components, clear installation sequence and less on-site processing requirements reduce the requirements for workers' skills, which is conducive to the rapid completion of construction under severe cold conditions. At the same time, the modular structure facilitates later inspection, maintenance and local repair, which helps to reduce long-term operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, a prefabricated composite wall for wintering in high-latitude and cold regions includes an exterior wall panel 3, a plurality of second hangers 7 are provided on the inner surface of the exterior wall panel 3, one side of an assembly net 2 is hung on the second hanger 7 of the exterior wall panel 3, an insulation material 4 and a moisture-proof material 5 are provided inside the assembly net 2, and a first hanger 6 is also provided, the first hanger 6 is arranged on the wall 1, and the other side of the assembly net 2 is hung on the wall 1, and a plurality of exterior wall panels 3 are overlapped to form an exterior wall surface.

[0028] First, install the first hanger 6 on the wall 1 according to the size, and place the thermal insulation material 4 and the moisture-proof material 5 in order inside the assembly net 2, with the moisture-proof material 5 inside and the thermal insulation material 4 outside. Hang multiple assembly nets 2 on the first hanger 6, and then assemble the exterior wall panels 3 in order. The exterior wall panels 3 are overlapped with each other to form a flat exterior wall surface.

[0029] The exterior wallboard 3 is used as the outer covering layer of the wall, providing aesthetics, protection and a certain degree of thermal insulation effect. A plurality of second hanging parts 7 are arranged on the inner surface thereof for connecting the assembly net 2.

[0030] The assembly net 2 serves as an internal skeleton structure, carries the thermal insulation material 4 and the moisture-proof material 5, and is hung on the wall 1 and the exterior wall panel 3. The design of the assembly net should ensure its strength, rigidity and stability to facilitate the installation and carrying of various materials.

[0031] The heat preservation material 4 is located inside the assembly net 2, close to one side of the wall 1, and is mainly responsible for reducing heat transfer and keeping the room warm. Its selection should take into account the harsh climate conditions in the high-cold areas to ensure excellent heat preservation performance and low temperature resistance.

[0032] The moisture-proof material 5 is located inside the thermal insulation material 4 and in direct contact with the assembly net 2. It mainly blocks moisture and prevents water penetration, thereby protecting the thermal insulation material from moisture and maintaining its thermal insulation performance.

[0033] The first hanging member 6 is pre-installed on the wall 1 and is used to fix the assembly net 2. The first hanging member should have good bearing capacity and durability to adapt to long-term use in a high-cold environment.

[0034] The second hanging piece 7 is arranged on the inner surface of the exterior wall panel 3 and cooperates with the assembly net 2 to achieve a stable connection between the exterior wall panel and the assembly net.

[0035] The first hanging member 6 is installed by accurately measuring and positioning according to the actual size of the wall 1 and the design requirements, and the first hanging member is firmly installed on the wall.

[0036] Place the heat-insulating material 4 and the moisture-proof material 5 according to the design sequence. First place the moisture-proof material 5 inside the assembly net 2, and then place the heat-insulating material 4 outside the moisture-proof material 5 to ensure that the two are positioned correctly and fit tightly.

[0037] Hanging the assembly net 2: Hang the assembly net 2 filled with heat-insulating and moisture-proof materials on the installed first hanger 6 to ensure that it is firmly connected without looseness.

[0038] The exterior wall panels 3 are assembled in a predetermined order, and multiple exterior wall panels 3 are sequentially hung on the assembly net 2 through the second hangers 7 on the inner surface thereof. Adjacent exterior wall panels should be overlapped to form a flat and continuous exterior wall surface, and at the same time ensure that the joints are well sealed to prevent air penetration and moisture invasion.

[0039] In the preferred embodiment, an opening is provided above the assembly net 2, a plurality of holes are provided around the assembly net 2, and the plurality of holes on both sides of the assembly net 2 are hung on the first hanging piece 6 and the second hanging piece 7, such as Figure 2-3 shown.

[0040] In the preferred embodiment, an outer lap plate 301 is provided on one side of the outer wall panel 3, and an inner lap plate 302 matching the outer lap plate 301 is provided on the other side of the outer wall panel 3. Figure 2-3 As shown, there is an opening at the top of the assembly net 2, which may be for the convenience of filling the insulation material 4 and the moisture-proof material 5 during the installation process, or to reserve a channel for other installation links "such as electrical lines, ventilation ducts, etc." This opening may need to be closed after filling to maintain the integrity of the internal materials and prevent external environmental influences.

[0041] There are multiple holes evenly distributed around the assembly net 2. These holes are designed with two main functions:

[0042] a. Hanging function: The holes on both sides of the assembly net 2 match the first hanger 6 on the wall 1 and the second hanger 7 in the exterior wall panel 3, respectively, so that the assembly net can be firmly hung on the wall and the exterior wall panel through these holes to form an integral wall structure system.

[0043] b. Ventilation: The holes may also have certain ventilation functions, which can help regulate the microclimate of internal thermal insulation and moisture-proof materials and prevent moisture accumulation, but this function needs to be coordinated with the air tightness and insulation requirements of the wall.

[0044] When filling the heat-insulating material 4 and the moisture-proof material 5, they can be placed and installed through the upper opening to ensure that the materials are evenly distributed and tightly filled.

[0045] The filled assembly net is hung on the pre-installed first hanging piece 6 through the holes around the circumference, ensuring that each hole fits tightly with the corresponding hanging piece without any looseness.

[0046] Similarly, after the exterior wall panel 3 is installed in place, it is hung on the second hanger 7 on the inner surface of the exterior wall panel through the holes on the other side of the circumference of the assembly net 2 to form a stable connection.

[0047] In the preferred embodiment, a composite adhesive strip 303 is provided on the inner surface of the outer lap plate 301 or the inner lap plate 302. The outer lap plate 301 and the inner lap plate 302 are overlapped and bonded together by the composite adhesive strip 303. The composite adhesive strip is made of a material with good bonding performance, weather resistance, aging resistance and low temperature adaptability, ensuring that a stable bonding effect can be maintained for a long time in high-latitude and cold regions.

[0048] The outer lap board 301 and the inner lap board 302 are overlapped and bonded together by the composite adhesive strips on their inner surfaces. Appropriate pressure may need to be applied during the bonding process to ensure that the adhesive strips are in full contact with the board to form an effective sealing interface. After the adhesive strips are cured, a firm and sealed connection is formed between the two boards, effectively preventing air and moisture from penetrating and maintaining the thermal insulation and moisture-proof properties of the wall interior.

[0049] In a preferred embodiment, after the plurality of assembly nets 2 are assembled on the exterior wall panel 3, the surfaces of the adjacent assembly nets 2 are attached to each other. Figure 1 As shown, after being bonded to each other, the heat-insulating material 4 and moisture-proof material 5 inside the assembly net 2 have a better effect.

[0050] The surface of the assembled mesh that fits together helps to form a continuous, closed moisture barrier. The moisture-proof material 5 is closely arranged inside the assembled mesh. After the adjacent assembled meshes are fitted together, the possibility of moisture penetrating from the gaps in the wall is reduced, and the overall moisture-proof performance of the wall is enhanced. This is particularly important for high-latitude and cold regions, because in cold climates, moisture may cause the performance of thermal insulation materials to decline, and even cause problems such as mildew and frost heave.

[0051] When adjacent assembly nets 2 are fitted together, the gap between them is minimized, reducing the possibility of thermal bridge effect. Thermal bridge effect refers to the fact that heat is more easily transferred through these "bridges" at the junction of different wall materials or components due to differences in thermal conductivity, thereby reducing the overall thermal insulation performance. The fitted assembly net surface can effectively reduce thermal bridges, allowing the thermal insulation material 4 to play a better insulation effect, reduce indoor heat loss, and maintain a stable indoor temperature.

[0052] In the preferred embodiment, a plurality of cement nails 601 are provided in the middle of the first hanging member 6, a through hole is provided at the lower end of the first hanging member 6, and a self-tapping screw 602 is provided inside the through hole. When installing the first hanging member 6, the cement nails 601 on the first hanging member 6 are nailed into the wall at the installation position using a hammer, and after the first hanging member 6 is stabilized, the self-tapping screws 602 are driven into the wall 1 using an electric drill.

[0053] According to design requirements, the installation position of the first hanging component 6 is marked on the wall 1 .

[0054] Initial fixation: Use a hammer to knock the cement nail 601 in the middle of the first hanging member 6 into the wall. This step uses the impact force and self-drilling ability of the cement nail to make it firmly embedded in the wall, providing initial fixation and support for the hanging member.

[0055] Reinforce the connection: After the cement nail 601 is fixed, use an electric drill to screw the self-tapping screw 602 into the through hole at the lower end of the first hanger 6, and drive it into the wall. The self-tapping screw has a self-tapping thread, which can form a thread by itself during the drilling process, forming a tight and firm mechanical connection with the wall, further enhancing the connection strength and stability between the hanger and the wall.

[0056] In the preferred embodiment, a main grouting hole 603 is provided inside the self-tapping screw 602, and a plurality of test grouting holes 604 are provided on the self-tapping screw 602, and the test grouting holes 604 are connected with the main grouting holes 603. After the self-tapping screw 602 is driven into the wall 1, it is connected with the main grouting hole 603 by a glue injection gun, and the glue injection gun injects glue into the main grouting hole 603, and the glue is discharged from the test grouting holes 604 into the wall 1, thereby increasing the stability of the self-tapping screw 602.

[0057] The main grouting hole 603 is located inside the self-tapping screw 602 and is the main channel for glue injection. The main grouting hole matches the glue injection gun interface, which is convenient for the glue injection gun to be directly inserted and communicated with it.

[0058] The side grouting holes 604 are distributed on the self-tapping screws 602 and are communicated with the main grouting holes 603. The function of these small holes is to allow the injected glue to be evenly discharged from the periphery of the self-tapping screws and enter the interior of the wall 1.

[0059] Grouting reinforcement process:

[0060] The self-tapping screw 602 is driven into the wall 1: First, according to the above method, the self-tapping screw 602 is screwed into the interior of the wall 1 with an electric drill to form a stable mechanical connection.

[0061] Connect the glue injection gun: After the self-tapping screw 602 is fully driven in, connect the nozzle of the glue injection gun with the main grouting hole 603 to ensure that the two are tightly connected.

[0062] Glue injection reinforcement: Start the glue injection gun and inject glue into the main grouting hole 603. The glue flows in along the main grouting hole and is evenly discharged through the side grouting hole 604 to the surrounding of the self-tapping screw 602 and the inside of the wall 1. This grouting operation is intended to:

[0063] a. Increase the stability of the screw: After the glue solidifies, a strong chemical bond will be formed between the self-tapping screw 602 and the wall 1, thereby enhancing the anchoring force of the screw inside the wall and preventing it from loosening due to vibration, stress changes, etc.

[0064] b. Sealing gaps: The glue injection process can fill the tiny gaps that may exist between the self-tapping screws 602 and the wall 1, improve the air tightness and waterproofness of the screw fixation, and help prevent moisture, cold air, etc. from penetrating into the wall through the screw holes and affecting the thermal insulation and moisture-proof performance.

[0065] In the preferred embodiment, the heat-insulating material 4 is a rubber-plastic heat-insulating material, or an aluminum silicate heat-insulating material. In this embodiment, the rubber-plastic heat-insulating material is preferred.

[0066] In a preferred embodiment, the moisture-proof material 5 is a moisture-proof gypsum board or a moisture-proof particle board. In this embodiment, moisture-proof gypsum board is preferred.

[0067] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
