Description

Technical Field

[0001] The invention relates to the technical field of composite walls, in particular to a thermal insulation and fireproof composite wall and an installation method thereof. Background Art

[0002] In the construction industry, with the increasing requirements for building energy conservation, safety and environmental protection, traditional wall materials can no longer meet the needs of modern buildings. Especially in cold areas or places that require high fire safety, the shortcomings of traditional walls in thermal insulation and fire resistance are becoming increasingly prominent. Therefore, the development of a composite wall device with both excellent thermal insulation and high-efficiency fire resistance has become an urgent need in the industry;

The thermal insulation layer of this solution is formed by plane splicing of Class A thermal insulation material and Class B thermal insulation material, and the end is provided with a mortise and tenon structure composed of Class B thermal insulation material. The Class A thermal insulation material enables this solution to be used as a fireproof isolation zone, and the mortise and tenon structure enables this solution to form an effective connection with the connecting plate, and since Class B thermal insulation material has better plasticity than Class A thermal insulation material, the mortise and tenon structure composed of Class B thermal insulation material can reduce the production difficulty of this solution;

[0071] Reference Figure 1 , Figure 2 and Figure 6 , which is the first embodiment of the present invention, is a thermal insulation and fireproof composite wall, comprising:

[0072] A wall structure, wherein the wall structure comprises an intermediate layer 201 and an outer mold layer 203, wherein the outer mold layer 203 is symmetrically arranged along the intermediate layer 201; the intermediate layer 201 adopts a lightweight, high-strength inorganic thermal insulation material, such as rock wool, glass wool or silicate board, which can effectively isolate indoor and outdoor heat transfer and improve the thermal insulation efficiency of the wall; the outer mold layer 203 is divided into an insulation layer 2032 and a fireproof layer 2033, wherein the insulation layer 2032 in the outer mold layer 203 faces the intermediate layer 201 and is used to insulate the interior of the wall structure, while the fireproof layer 2033 of the outermost layer of the wall is used to prevent damage caused by burning the wall by flames, and the outer mold layer 203 adopts high-strength, corrosion-resistant reinforced concrete or precast concrete slabs, which not only provides structural support, but also enhances the overall strength and durability of the wall;

[0073] A support structure 202, wherein the support structure 202 includes a monomer structure or a composite structure, and the support structure 202 is used to connect the outer mold layer 203 and the middle layer 201;

[0074] The reinforcing ribs 2031 are connected to the outer formwork layer 203 and used to connect the supporting structure 202 to provide positioning for the supporting structure 202; the reinforcing ribs 2031 use high-strength steel bars or fiber-reinforced composite materials to improve the shear strength and seismic performance of the wall, and the reinforcing ribs 2031 are connected to the outer formwork layer 203 by embedded parts or welding, and are fixed to the steel structure layer by plugging to form a stable support system.

[0075] The bearing wall 1, the wall structure is sequentially spliced ​​in an array along a single direction of the installation position, and the two ends after splicing are respectively connected to the bearing wall 1.

[0076] Preferably, the support structure 202 includes a monomer structure, which includes a steel structure layer, which is hinged and fixed on the middle layer 201 through oblique plug wires, and the outer mold layer 203 is inserted into the steel structure layer through reinforcing ribs 2031, and is fixedly installed on both sides of the middle layer 201 in conjunction with cement pouring to form a reinforced structure.

The oblique plug wire is made of high-strength stainless steel to ensure stable and reliable connection. At the same time, the support structure 202, as a key component connecting the outer mold layer 203 and the middle layer 201, ensures the overall stability and load-bearing capacity of the wall.

[0077] To summarize, first clean the installation position to ensure that the ground is flat and free of debris, then place the steel structure layer according to the designed position, and fix it on the middle layer 201 through oblique screw hinges, then hoist the outer mold layer 203 to the installation position in turn, connect it to the steel structure layer through reinforcing ribs 2031, ensure that the outer mold layer 203 and the middle layer 201 fit tightly, then pour high-strength cement between the outer mold layer 203 and the middle layer 201, and after the cement solidifies, form a solid reinforced structure, finally, splice the wall structure in an array in a single direction along the installation position in turn, ensure that the splicing gap is tight, and connect the two ends after splicing to the bearing wall 1 through embedded parts or expansion plugs.

[0078] Example 2

[0079] Reference Figure 1-Figure 2 , which is the second embodiment of the present invention, and is based on the previous embodiment, a thermal insulation composite wall, wherein the composite structure comprises a detachably installed steel structure layer, wherein the steel structure layer is divided into an installation component and a splicing piece;

[0080] The mounting assembly includes a mounting ball 2027 and a mounting rod 2028. The mounting ball 2027 is provided with a plurality of threaded mounting holes circumferentially, and the mounting rod 2028 is fixedly connected to the mounting ball 2027 by means of threaded fitting.

[0081] The splicing parts are divided into steel component 1 and steel component 2, and the steel component 1 is coupled to the steel structure 2. The ends of the steel component 1 and the steel component 2 that are away from each other are respectively provided with mounting bolts. The steel component 1 and the steel component 2 are respectively threaded with mounting tubes 2026 through the mounting bolts. The mounting tubes 2026 are provided with hemispherical grooves for installing the mounting balls 2027. At the same time, the mounting tubes 2026 are symmetrically provided with mounting grooves on both sides, and the width of the mounting grooves is greater than the thread diameter of the mounting rod 2028.

[0082] Preferably, the first steel member comprises a connecting pipe 2021 and a locking pipe 2023 arranged on the outer wall of the connecting pipe 2021, the outer wall of the locking pipe 2023 is provided with a coupling slope 2024, a boss is provided on the upper surface of one end of the coupling slope 2024, and a step is provided at one end of the coupling slope 2024;

[0083] The second steel component includes a locking rod 2025, a coupling hole matching the coupling slope 2024 is provided on the locking rod 2025, a slider is provided on the locking rod 2025, a sliding member 2022 is provided on the locking rod 2025 through the matching sliding of the slider and the sliding groove, an abutment block is provided on the sliding member 2022, and the abutment block unlocks or locks the steel components one and two by matching the coupling hole and the coupling slope 2024, the locking rod 2025 is provided with a coupling hole matching the coupling slope 2024, when the locking rod 2025 is inserted into the connecting pipe 2021, the coupling hole and the coupling slope 2024 are matched to achieve locking, the sliding member 2022 is slidably sleeved on the locking rod 2025, and the abutment block provided thereon matches the coupling slope 2024 through the coupling hole to unlock or lock. When unlocking is required, the abutment block can be moved to different positions in the coupling hole by moving the position of the sliding member 2022. When the abutment block is located at different positions in the coupling hole, the pressing conditions of the abutment block on the coupling slope are different. When the sliding member 2022 drives the abutment block to move to the boss position on the coupling slope 2024, the coupling slope 2024 is pressed down accordingly and remains parallel to or lower than the outer wall of the locking rod 2025. At this time, steel component one and steel component two are unlocked. Conversely, when the sliding member 2022 drives the abutment block to move to the non-boss position on the coupling slope 2024, the coupling slope 2024 will not move down, thereby being clamped in the coupling hole, so that steel component one and steel component two are locked.

At the same time, steel component 1 and steel component 2 are respectively installed at the positions where they need to be connected. By the cooperation of the locking rod 2025 and the connecting pipe 2021, and the locking of the sliding part 2022 and the coupling slope 2024, the steel components can be quickly connected. At the same time, the hemispherical groove on the mounting cylinder 2026 is used to cooperate with the mounting ball 2027 and the mounting rod 2028 to achieve more complex connection and fixation.

[0086] When disassembling steel component 1 and steel component 2, slide the sliding member 2022 to disengage the abutment block from the locking position of the coupling slope 2024, and gently pull out the locking rod 2025 to separate steel component 1 and steel component 2. If needed, the mounting ball 2027 and the mounting rod 2028 can be removed to adjust or repair the wall structure, and the reinforcing ribs 2037 on the load-bearing wall 1 are all replaced with steel component 2.

[0119] Step P2.3: Determine the specific quantity and distribution of the installation balls 2027 and installation rods 2028 according to the positions and requirements in the simulated wall structure. Meanwhile, determine the specific dimensions and mating methods of the locking pipes 2023, locking rods 2025, sliding members 2022 and abutting blocks according to the connection mechanism between the first steel member and the second steel member.

[0120] Step P2.4: Conduct a comprehensive evaluation of the determined intermediate layer 201, outer mold layer 203, support structure 202 and reinforcing ribs 2031 to ensure that all dimensions and mating methods meet the design requirements.

[0121] Preferably, the specific process of step P4 is as follows:

[0122] Step P4.1: Simulate the installation of the completed composite wall 2 in the foundation pit, and test through CAD the sizes of the gaps reserved on both sides between the composite wall 2 and the bearing wall 1 during the installation process.

[0123] Step P4.2: According to the sizes of the reserved gaps obtained from the simulation, simulate the connection method of disassembling and assembling the composite wall 2 to obtain a supplementary wall with the actual gap size.

[0124] Step P4.3: Conduct a simulated assembly according to the composite wall 2 and the supplementary wall obtained from the simulation.

[0125] Step P4.4: Obtain the smoothness N of the wall according to the simulation results, set the sampling interval of the temperature as t, sample the temperature, obtain the temperature values T1 and T2 of the wall, and calculate the temperature change rate of the wall

[0126] Step P4.5: Set the effective range of the smoothness as [n1, n2], and the effective range of the temperature change rate as [Q1, Q2], and determine whether the structure of the simulated assembly meets the design requirements of the wall; if n1 ≤ N ≤ n2 and Q1 ≤ ΔT ≤ Q2, the result of the simulated assembly meets the design requirements; if N < n1 or N > n2 or ΔT < Q1 or ΔT > Q2, the result of the simulated assembly does not meet the design requirements, and return to step P4.1;

[0127] Step P4.6: Output the structures of the composite wall 2 and the supplementary wall, and conduct an actual assembly.

[0128] Before the actual assembly, it is necessary to confirm that the structure of the simulated assembly meets the design requirements of the wall, and select appropriate wall materials according to the size, shape and load to be borne by the supplementary wall; meanwhile, determine the construction process of the supplementary wall and necessary reinforcement measures.

[0129] According to the simulation results, prepare the required supplementary wall materials, connectors, fixtures, and necessary construction tools and equipment, mark the installation position of the supplementary wall on the load-bearing wall 1, ensure that the installation position is accurate, install the supplementary walls one by one into the reserved gaps in accordance with the simulated loading method, and use connectors and fixtures to firmly fix them on the load-bearing wall 1. At the same time, during the installation process, perform real-time inspections on the installation quality of the supplementary walls to ensure that the wall installation is flat, firm, and meets the design requirements;

[0130] After the installation of the supplementary wall is completed, continue to sample and monitor the temperature of the wall to ensure that the temperature change rate of the wall is within the design range to avoid cracking or deformation of the wall due to temperature changes. At the same time, use measuring tools to monitor the smoothness of the wall to ensure that the smoothness of the wall meets the design requirements to improve the overall aesthetics and service life of the wall;

[0131] Conduct detailed analysis of temperature and smoothness monitoring data to identify possible problems or deficiencies. Based on the analysis results, make necessary adjustments and optimizations to the installation location, connection method or material selection of the supplementary wall to ensure the overall performance and stability of the wall;

[0132] In summary, in step P4, the size of the gap between the composite wall and the load-bearing wall is tested through CAD simulation, and the corresponding supplementary wall is designed. During the simulated loading process, not only the structural stability and smoothness of the wall are tested, but also temperature monitoring is added to ensure that the temperature change rate of the wall is within the design range. At the same time, the material and process selection of the supplementary wall, the actual installation steps, and the temperature and smoothness monitoring methods are described in detail. These measures jointly ensure the installation quality of the thermal insulation and fireproof composite wall and improve the overall performance and stability of the wall.
