Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall insulation technology, and in particular to an integrated external wall insulation structure. Background Technology
[0002] To improve the thermal insulation performance of building walls, prefabricated insulation panels are typically installed on the exterior walls. Currently, these panels are usually installed on the exterior surface of the wall using methods such as bonding, anchoring, or external hanging. Bonding methods are prone to causing voids between the prefabricated insulation panels and the structural wall; anchoring methods are prone to the panels separating from the building structure due to aging and deformation of the anchors; and external hanging methods use large-sized prefabricated insulation panels, resulting in low installation efficiency and the seams being prone to water accumulation and freezing cracking.
[0003] In existing technologies, one method involves fixing insulation boards to the outside of the base wall through casting. Specialized equipment is used to prefabricate steel wire mesh polystyrene boards, which are then embedded into the concrete wall using prefabrication or cast-in-place methods. This creates a novel reinforced concrete composite shear wall structure, ensuring that the insulation boards do not shift or deform, improving construction quality and efficiency. Furthermore, it achieves the effect of preventing building demolition and insulation damage, effectively solving problems such as easy detachment and fire hazards associated with building insulation.
[0004] However, the method of using hooks on the outside of the base wall to support and limit the insulation board can easily cause the insulation board to shift and tilt during pouring, resulting in unevenness between the insulation boards and affecting the insulation performance. Utility Model Content
[0005] The purpose of this utility model is to solve the problems in the existing technology of poor support and limiting effect of insulation board, and the insulation board is prone to unevenness, which affects the insulation performance. Therefore, an integrated external wall insulation structure is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An integrated external wall insulation structure includes an insulation board and multiple sets of fixing columns for fixing the insulation board, all fixedly installed on the outside of the base wall. The insulation board has multiple through holes penetrating the wall thickness. The fixing columns extend out of the insulation board through the through holes. A limiting ring is fixedly installed near the center of each fixing column, with one side of the insulation board abutting against the limiting ring. A retaining ring is threaded to the end of the fixing column away from the base wall, and the other side of the insulation board abuts against the retaining ring. A wire mesh is installed at the end of the fixing column away from the base wall, with a concrete layer between the wire mesh and the base wall.
[0008] To facilitate the connection between the inner and outer concrete of the insulation board, preferably, the fixing column has a central hole and multiple clearance grooves connected to the central hole are provided on the side wall of the fixing column, and the length of the clearance groove is greater than the thickness of the insulation board.
[0009] To facilitate the fixing of the wire mesh, preferably, the inner wall of the wire mesh abuts against the end of the fixing post away from the base wall, and the wire mesh is fixed to the fixing post by binding wire.
[0010] To facilitate the pouring of concrete on the outside of the insulation board and the inside of the wire mesh, preferably, a gap is left between the inner wall of the wire mesh and the outer wall of the insulation board, and the gap size ranges from mm to mm.
[0011] Preferably, the retaining ring has a polygonal cross-section.
[0012] Preferably, a groove is formed on the outer end face of the through hole, the retaining ring is located in the groove, and the depth of the groove is greater than the thickness of the retaining ring, and the inner diameter of the groove is greater than the outer diameter of the retaining ring.
[0013] Compared with the prior art, this utility model provides an integrated external wall insulation structure, which has the following beneficial effects:
[0014] 1. This integrated external wall insulation structure uses fixed columns to fix the outer wall of the base wall, and fixed limiting rings to the fixed columns. This not only limits the inner wall of the insulation board, leaving a gap between the inner wall of the insulation board and the outer wall of the base wall, but also uses threaded retaining rings to fix the insulation board to the fixed columns. The inner wall of the retaining rings abuts against the outer wall of the insulation board, thus fixing the insulation board to the fixed columns. With the fixation of multiple sets of fixed columns, the position of the insulation board can be guaranteed, reducing the occurrence of skew and displacement, and improving the effect.
[0015] 2. This integrated external wall insulation structure, by having a central hole in the fixed column and a clearance groove in the side wall of the fixed column, allows the concrete to fill the central hole and clearance groove during concrete pouring and extend to the outside of the insulation board, making the concrete on the inside and outside of the insulation board a whole and improving its strength.
[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model fixes a fixed column to the outer wall of the base wall and a limiting ring to the fixed column. This not only limits the inner wall of the insulation board, leaving a gap between the inner wall of the insulation board and the outer wall of the base wall, but also secures the insulation board to the fixed column by threading a retaining ring to the fixed column and abutting the inner wall of the retaining ring against the outer wall of the insulation board. By fixing the insulation board with multiple sets of fixed columns, the position of the insulation board can be guaranteed, reducing the occurrence of skew and displacement, and improving the implementation effect.

[0024] Example:
[0025] Reference Figures 1-4An integrated external wall insulation structure includes an insulation board 1 and multiple sets of fixing columns 2 for fixing the insulation board 1, all fixedly installed on the outside of the base wall. One end of the fixing column 2 located inside the base wall can be pre-embedded during the pouring of the base wall, or a steel mesh frame can be fixed on the outside of the base wall, and the fixing column 2 can be fixed to the steel mesh frame by welding. Preferably, a steel mesh frame is welded to the outside of the base wall. Multiple through holes 101 penetrating the wall thickness are provided on the insulation board 1. There are two to ten through holes 101; here, five are preferred, located at the center of the insulation board 1 and near the perimeter. At the corners, meaning a maximum of five fixing posts 2 are needed for one insulation board 1, each of the five fixing posts 2 extends out of the insulation board 1 through the through hole 101. A limit ring 201 is fixedly installed near the middle of the fixing post 2, with one side of the insulation board 1 abutting against the limit ring 201. A retaining ring 3 is threadedly connected to the end of the fixing post 2 away from the base wall. The axial section of the retaining ring 3 is polygonal, which can be quadrilateral, pentagonal, or hexagonal. Here, we prefer a hexagonal shape, and its size is compatible with commonly used open-end wrenches and socket wrenches to facilitate the rotation of the retaining ring 3. The other side of the insulation board 1 abuts against the retaining ring 3. By setting a limiting ring 201, the inner wall of the insulation board 1 can be limited, leaving a gap between the inner wall of the insulation board 1 and the outer wall of the base wall. Then, a retaining ring 3 is threaded onto the fixing column 2, with the inner wall of the retaining ring 3 abutting against the outer wall of the insulation board 1, thus fixing the insulation board 1 to the fixing column 2. Through the fixing of multiple sets of fixing columns 2, the position of the insulation board 1 can be guaranteed, reducing the occurrence of tilting and displacement, and improving the overall effect. A wire mesh 4 is set at the end of the fixing column 2 away from the base wall. The wire mesh 4 is located on the outside of the insulation board 1, and a gap is left between the inner wall of the wire mesh 4 and the outer wall of the insulation board 1. The gap size ranges from [missing value]. The thickness ranges from 10mm to 50mm, with 20mm being the preferred thickness. A concrete layer 5 is installed between the wire mesh 4 and the base wall. In other words, a template is fixed to the outside of the wire mesh 4. After the insulation board 1 is installed, concrete is poured between the inner wall of the template and the outer wall of the base wall. Once the concrete has solidified, a concrete layer 5 is formed that wraps around the insulation board 1, thus constructing a new type of reinforced welded mesh concrete composite shear wall structure. This ensures that the insulation board 1 does not shift or deform, improving construction quality and efficiency. It also achieves the effect of not demolishing the building and not damaging the insulation, effectively solving problems such as easy detachment and fire of building insulation.
[0026] In use, a fixing column 2 is fixedly installed on the outer wall of the base wall, and a limiting ring 201 is fixedly installed on the fixing column 2. This not only limits the inner wall of the insulation board 1, leaving a gap between the inner wall of the insulation board 1 and the outer wall of the base wall, but also secures the insulation board 1 to the fixing column 2 by threading a retaining ring 3 onto the fixing column 2 and abutting the inner wall of the retaining ring 3 against the outer wall of the insulation board 1. Through the fixing of multiple sets of fixing columns 2, the position of the insulation board 1 can be guaranteed, reducing the occurrence of tilting and displacement, and improving the effect.
[0027] Reference Figure 4 A central hole 202 is provided on the fixed column 2, and multiple clearance grooves 203 connected to the central hole 202 are provided on the side wall of the fixed column 2. The length of the clearance grooves 203 is greater than the thickness of the insulation board 1. There are two to ten clearance grooves 203. Here, we prefer four, and the four are evenly distributed in a circle. In use, by providing a central hole 202 on the fixed column 2 and clearance grooves 203 on the side wall of the fixed column 2, when pouring concrete, the concrete can fill the central hole 202 and clearance grooves 203 and extend to the outside of the insulation board 1. This can make the concrete on the inner and outer sides of the insulation board 1 become a whole and improve the strength.
[0028] Reference Figures 1-3 The inner wall of the wire mesh 4 is abutted against the end of the fixing post 2 away from the base wall, and the wire mesh 4 is fixed to the fixing post 2 with tie wire. That is to say, the cross joint of the wire mesh 4 is tied to the end of the fixing post 2 that extends out of the insulation board 1 with tie wire. This not only fixes the wire mesh 4, but also creates a gap between the outer wall of the insulation board 1 and the inner wall of the wire mesh 4 through the fixing post 2. Concrete can be poured into the gap to improve the fixing effect of the insulation board 1. Moreover, fixing the wire mesh 4 on the outside of the insulation board 1 improves the impact resistance and crack resistance. The particle size of the sand and gravel in the concrete should be less than 6mm, or mortar can be used directly.
[0029] Reference Figures 1-3 A recessed groove 102 is provided on the outer end face of the through hole 101. That is, the recessed groove 102 is provided on the outer wall of the insulation board 1. The retaining ring 3 is located inside the recessed groove 102, and the depth of the recessed groove 102 is greater than the thickness of the retaining ring 3. Moreover, the inner diameter of the recessed groove 102 is greater than the outer diameter of the retaining ring 3. In use, by providing a recessed groove 102 on the outer wall of the insulation board 1 and having the retaining ring 3 located inside the recessed groove 102, the interference of the retaining ring 3 on the wire mesh 4 can be reduced, thereby improving the performance.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
