Abstract
Description
Technical Field
[0001] This invention relates to the field of external wall insulation for prefabricated buildings, and specifically to prefabricated building external wall insulation and pressure-resistant insulation boards. Background Technology
[0002] Currently, in prefabricated cast-in-place wall panels for external insulation in prefabricated buildings, a single insulation board is mainly used. No measures are taken to strengthen the compressive strength of the board itself to resist external pressure. In actual use, due to the large lateral pressure of concrete pouring, the wall is squeezed and deformed, resulting in unevenness and large deformation, and a large amount of subsequent repair work.
[0003] While using existing steel reinforcement bars as auxiliary supports can improve compressive strength and reduce material deformation, steel is a highly thermally conductive material, which creates severe thermal bridging and results in a high thermal conductivity of the wall, significantly reducing its insulation effect. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a prefabricated building exterior wall thermal insulation and pressure-resistant insulation board, including an insulation board, an outer pressure-bearing panel at the front end of the insulation board, an inner pressure-bearing panel at the rear end of the insulation board, and the outer pressure-bearing panel and the inner pressure-bearing panel are self-locked by a pressure-bearing rod penetrating the insulation board to form an integral thermal insulation structural board suitable for use in prefabricated building exterior walls.
[0005] Preferably, the outer pressure-bearing panel has first insertion parts arranged at equal intervals on both sides, and a first snap-fit part is provided between two adjacent first insertion parts. The outer pressure-bearing panel has plate holes arranged in a mesh pattern, and first reinforcing ribs are arranged crosswise on the outer pressure-bearing panel. Insertion holes are provided at the intersection of the first reinforcing ribs for inserting pressure-bearing rods.
[0006] Preferably, the inner pressure-bearing panel has second insertion parts arranged at equal intervals on both sides, and a second snap-fit part is provided between two adjacent second insertion parts.
[0007] Preferably, the inner pressure-bearing panel has plate holes arranged in a mesh pattern, and a second reinforcing rib is arranged crosswise on the inner pressure-bearing panel. The second reinforcing rib has a locking hole corresponding to the insertion hole, and the locking hole is flat.
[0008] Preferably, the pressure-bearing member includes a pressure-bearing rod, one end of which is fixedly connected to a rod cap. The diameter of the rod cap is larger than the diameter of the pressure-bearing rod, and a slot is provided on the outer wall of the rod cap.
[0009] Preferably, the other end of the bearing rod is fixedly connected to a connecting rod, the diameter of the connecting rod is smaller than the diameter of the bearing rod, and the other end of the connecting rod is connected to a self-locking part, which is flat near the connecting rod.
[0010] Preferably, the insulation board can be a fiber insulation board or a mesh-woven pressurized fiber insulation board.
[0011] Preferably, the outer pressure-bearing panel and the inner pressure-bearing panel can be made of inorganic board or flame-retardant organic board, including but not limited to basalt board or fiberglass board, and are formed by mechanical molding in one go.
[0012] Preferably, the outer and inner pressure-bearing panels are 3-6mm thick and are rectangular mesh sheets formed by pressing.
[0013] Preferably, the pressure-bearing rod is made of non-metallic, non-thermal-conducting materials, including but not limited to inorganic basalt and flame-retardant nylon, polyethylene, and polypropylene materials, and is formed by one-time casting or pressing using mechanical molds.
[0014] The technical effects and advantages of this invention are as follows:
[0015] 1. In this invention, the outer and inner pressure-bearing panels clamp the original non-pressure-resistant transverse fiber insulation material, evenly distributing the stress points on the outer and inner pressure-bearing panels. The stress is transferred to the pressure-bearing members through the outer and inner pressure-bearing panels, thus protecting the middle insulation material from deformation under pressure. At the same time, it improves the compressive strength of the fiber insulation material. The resulting composite insulation board structure has a smooth surface that requires no repair, effectively protecting the middle insulation core material from damage and enhancing the protective capability of the insulation core material.
[0016] 2. In this invention, the outer pressure-bearing panel, the inner pressure-bearing panel, and the pressure-bearing rods are molded or extruded in the factory, resulting in regular shapes, extremely high processing precision and production efficiency, convenient assembly, and safe construction.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0023] Please see Figure 1 In this embodiment, a prefabricated building exterior wall thermal insulation and pressure-resistant insulation board is provided, including an insulation board 1. The insulation board 1 can be a fiber insulation board or a mesh-woven pressurized fiber insulation board. The front end of the insulation board 1 is provided with an outer pressure-bearing panel 2, and the rear end of the insulation board 1 is provided with an inner pressure-bearing panel 3. The outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 are self-locked together by a pressure-bearing rod 4 that penetrates the insulation board 1 to form an integral thermal insulation structural board suitable for prefabricated building exterior walls.
[0024] Among them, the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 can be made of inorganic board or flame-retardant organic board, including but not limited to basalt board or fiberglass board. They are pressed in one piece by mechanical mold in the factory. The thickness of the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 is 3-6mm. The outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 are rectangular mesh boards that have been pressed.
[0025] The pressure-bearing member 4 is made of non-metallic, non-thermal-conducting materials, including but not limited to inorganic basalt and flame-retardant nylon, polyethylene, and polypropylene materials. It is cast or pressed in one go in the factory using mechanical molds, which most effectively prevents the generation of "thermal bridges" and improves the insulation effect of the wall. The pressure-bearing member 4 is made of inorganic basalt or flame-retardant plastic or nylon non-thermal-conducting materials with locking fasteners in one go using a mold with a diameter of 6mm-8mm. The length of the pressure-bearing member is the thickness of the insulation board plus the thickness of the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 and the thickness of the embedded concrete.
[0026] Fiber insulation boards are made of fiber materials, such as rock wool, mineral wool, glass wool, or aluminum silicate ceramic wool. The thickness is generally 50mm to 120mm, the thermal conductivity is ≤0.035 [W / (mk)], and the density is 120kg / m³. 3 ~160kg / m 3 ;
[0027] Woven fiber insulation boards are reinforced insulation boards made by stitching together basalt fiber twisted yarn with fiberboard and a glass fiber mesh or basalt fiber mesh covering the surface. They typically have a thickness of 50mm to 120mm, a thermal conductivity of ≤0.035 [W / (mk)], and a density of 120kg / m³. 3 ~160kg / m 3 Basalt fiber yarn (linear density 500 tex ~ 800 tex), alkali-resistant glass fiber mesh (unit area mass 120 g / m²) 2 ~160g / m 2 A mesh-reinforced composite insulation board made of stitched parts.
[0028] The outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 clamp the original non-pressure-resistant horizontal fiber insulation material, evenly distributing the stress points on the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3. The stress is then transferred to the pressure-bearing member 4 through the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3. This protects the insulation material in the middle from deformation under pressure, while simultaneously improving the compressive strength of the fiber insulation material. The resulting composite insulation board structure has a smooth surface that requires no finishing. The core material of the insulation composite board is an inorganic fiber material with a low density (120-160 kg / m³). 3 It has excellent thermal insulation performance (thermal conductivity ≦0.035 [W / (mk)]) and a high fire resistance rating, all of which are Class A.
[0029] Example 2
[0030] Please see Figure 2 In this embodiment, the outer pressure-bearing panel 2 has first insertion parts 201 arranged at equal intervals on both sides of the outer pressure-bearing panel 2, and a first snap-fit part 202 is provided between two adjacent first insertion parts 201. When the two outer pressure-bearing panels 2 are connected, the first insertion part 201 of one outer pressure-bearing panel 2 is embedded in the first snap-fit part 202 of the other outer pressure-bearing panel 2 to fix the two outer pressure-bearing panels 2. The outer pressure-bearing panel 2 has plate holes 203 arranged in a mesh pattern, and the outer pressure-bearing panel 2 has first reinforcing ribs 204 arranged crosswise. The first reinforcing ribs 204 have insertion holes 205 at the intersection of the first reinforcing ribs 204. The insertion holes 205 are used to insert the pressure-bearing rod 4.
[0031] Please see Figure 3In this embodiment, the inner pressure-bearing panel 3 has second insertion parts 301 arranged at equal intervals on both sides of its side walls. A second snap-fit part 302 is provided between two adjacent second insertion parts 301. When the two inner pressure-bearing panels 3 are connected, the second insertion part 301 of one inner pressure-bearing panel 3 is embedded into the second snap-fit part 302 of the other inner pressure-bearing panel 3, thus fixing the two inner pressure-bearing panels 3. The inner pressure-bearing panel 3 has plate holes 203 arranged in a mesh pattern. The inner pressure-bearing panel 3 has second reinforcing ribs 303 arranged crosswise. The second reinforcing ribs 303 have locking holes 304 corresponding to the insertion holes 205. The locking holes 304 are flat and are used for inserting the end of the pressure-bearing rod 4. The inner pressure-bearing panel 3 also has grooves 305 on its two opposite sides. When concrete is poured into the inner pressure-bearing panel 3 near the wall, the concrete flows into the plate holes 203 and the grooves 305. The design of the grooves 305 increases the adhesion between the concrete and the inner pressure-bearing panel 3 and improves the stability of the insulation board structure.
[0032] Please see Figure 4 In this embodiment, the pressure-bearing rod 4 includes a pressure-bearing rod 401. One end of the pressure-bearing rod 401 is fixedly connected to a rod cap 402. The diameter of the rod cap 402 is larger than the diameter of the pressure-bearing rod 401. A slot 403 is provided on the outer side wall of the rod cap 402. The other end of the pressure-bearing rod 401 is fixedly connected to a connecting rod 404. The diameter of the connecting rod 404 is smaller than the diameter of the pressure-bearing rod 401. The other end of the connecting rod 404 is connected to a self-locking part 405. The self-locking part 405 is flat near the connecting rod 404. The self-locking part 405 passes through a locking hole 304. When the rod cap 402 is rotated, the pressure-bearing rod 4 rotates, so that the wider edge of the self-locking part 405 is locked on both sides of the locking hole 304, thereby fixing the pressure-bearing rod 4 to the outer pressure-bearing panel 2, the inner pressure-bearing panel 3, and the insulation board 1.
[0033] The working principle of this invention is:
[0034] During installation, the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 are placed on both sides of the insulation board 1, respectively. The pressure-bearing rod 4 is inserted into the insertion hole 205, passes through the insulation board 1 and exits through the locking hole 304. The workpiece is inserted into the slot 403 and the rod cap 402 is rotated so that the longer edge of the self-locking part 405 is offset from the longer edge of the locking hole 304, thereby fixing the pressure-bearing rod 4 to the outer pressure-bearing panel 2, the inner pressure-bearing panel 3 and the insulation board 1. The installation method is that the pressure-bearing rod 4 with its own locking structure is inserted into the insulation board 1, and the outer pressure-bearing panel 2 and the inner pressure-bearing panel 3 covering the upper and lower surfaces of the insulation board 1 are automatically locked together to form an insulation structure board with high overall compressive strength.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
