Description

Technical Field

[0001] This utility model belongs to the technical field of external wall insulation boards, specifically relating to an integrated structure external wall insulation board. Background Technology

[0002] In existing buildings, to improve their thermal insulation, insulation boards are usually installed on the outside of the exterior wall after it has been formed, by means of hanging. The thermal insulation performance of the wall is improved by the exterior wall insulation boards. In order to meet the national requirements for the fire performance of buildings, fireproof materials are usually added inside the insulation boards to expand their fire protection function.

[0003] The current technical problems encountered are: 1. Existing fireproof boards are installed after the wall is formed, which is relatively complex. After long-term use, in severe weather such as strong winds, the insulation boards are prone to detaching from the wall, causing significant safety hazards; 2. The common structure of existing insulation boards is to set extruded polystyrene (XPS) boards, with mesh cloth and high-strength mortar on the sides of the XPS boards. However, during installation, the XPS boards alone provide the main thermal insulation function, which is limited in effectiveness; 3. Those skilled in the art have attempted to fix STP boards directly to the exterior wall, but this requires drilling holes in the insulation boards. This drilling action damages the integrity and sealing of the STP boards, resulting in the loss or weakening of their thermal insulation performance.

[0004] Given the current problems with insulation boards, as a building materials research and design unit, it is essential for the applicant to improve the existing insulation board structure and production process, and design an integrated structural exterior wall insulation board that is structurally sound and easy to produce. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an integrated structural exterior wall insulation board with a novel structural design. By modifying the structure of the insulation board using existing molding equipment, it can achieve the molding of a board with high strength and good thermal insulation performance.

[0006] To achieve the above technical objectives, the present invention adopts the following solution: An integrated structural exterior wall insulation board includes a base plate, one side of which is provided with a lower mortar layer and a lower mesh cloth is provided inside the lower mortar layer; an insulation groove is provided on the other side of the base plate, a core material mortar layer is provided inside the insulation groove, an insulation core material is laid flat inside the insulation groove, an upper mortar layer is laid on top of the insulation core material, and an upper mesh cloth is provided inside the upper mortar layer.

[0007] The outer surface of the structural exterior wall insulation board is marked with a marking area, which corresponds to the ribs between the insulation grooves.

[0008] The upper mortar layer includes a filling mortar layer, on which a reinforcing mesh is laid, and on which a sealing mortar layer is provided.

[0009] The outer surface of the integrated structural exterior wall insulation board is covered with an outer mortar layer, which covers the entire perimeter of the integrated structural exterior wall insulation board.

[0010] The integrated structural exterior wall insulation board is provided with several through holes, which are located on the ribs or on the square insulation core material of less than 40 square centimeters.

[0011] The insulation groove is lined with an insulation mesh fabric, and a layer of core material mortar is sprayed onto the mesh fabric. Laying the insulation core material flat on the core material mortar layer can improve the bonding strength of the insulation core material.

[0012] The insulation core material consists of a sealing bag and an insulation board. The outer side of the sealing bag is a fiberglass woven layer, and the inner side is an aluminum foil layer or a thermosetting adhesive layer. When the inner side is an aluminum foil layer, thermosetting adhesive needs to be sprayed onto the aluminum foil layer.

[0013] The outer surface of the insulation board is provided with a textured or uneven surface, which increases the contact area between the outer surface of the insulation board and the aluminum foil layer or thermosetting adhesive layer.

[0014] The beneficial effects of this utility model are as follows: This utility model discloses an integrated structure exterior wall insulation board, which integrates a vacuum board as the insulation core material with the existing insulation board structure. This fully utilizes the insulation and sealing properties of the vacuum structure's insulation core material. During installation, the integrated structure exterior wall insulation board can be directly used as a template, eliminating the need for secondary disassembly during exterior wall forming. It is directly fixed inside the wall, ensuring wall insulation while effectively preventing insulation board detachment. The manufacturing process of this integrated structure exterior wall insulation board is simple, and existing polystyrene insulation board and extruded board molding equipment can be used. During the transition between old and new production methods, the equipment can be continuously used, increasing its utilization rate and reducing its scrap rate. Attached Figure Description

[0016] The present invention will be described in detail below through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification; however, it should be noted that the specific embodiments described below do not limit the technical solution. The scope of protection of this patent application is determined by the claims.

[0017] Example 1: An integrated structural exterior wall insulation board includes a board body 1, which is based on a substrate board. In this embodiment, the substrate board is a Class A fireproof insulation board 3. A lower mortar layer 2 is provided on one side of the Class A fireproof insulation board 3, and a lower mesh cloth 21 is provided inside the lower mortar layer 2. An insulation groove 30 is processed on the other side of the Class A fireproof insulation board 3. Ribs 33 are provided between every two adjacent insulation grooves 30 and between the insulation groove 30 and the outer edge. The width of the ribs is greater than 20 mm. In this embodiment, the overall thickness of the integrated structural exterior wall insulation board is 6 cm, and the thickness of the Class A fireproof insulation board 3 is 5.4 cm, wherein the groove depth is 2.5 to 2.7 cm from the outer perimeter.

[0018] After the insulation trough 30 is grooved, before laying the insulation core material 4, a core material mortar layer 31 is set inside the insulation trough 30. The insulation core material 4 is laid flat inside the insulation trough 30. In order to further improve the bonding strength of the insulation core material 4 in the insulation trough 30, before spraying the core material mortar layer 31 inside the insulation trough 30, a layer of insulation trough mesh cloth 32 is first laid inside the insulation trough 30. Then, a layer of core material mortar layer 31 is sprayed on the insulation trough mesh cloth 32, so that the core material mortar layer 31 soaks the insulation trough mesh cloth 32. Finally, the insulation core material 4 is laid flat on the core material mortar layer 31, which can make the bonding strength of the insulation core material 4 even higher.

[0019] After the insulation core material 4 is bonded, an upper mortar layer 5 is laid on top of the insulation core material 4, and an upper mesh fabric is provided inside the upper mortar layer. More specifically, in this embodiment, the upper mortar layer 5 includes a filling mortar layer 51. The filling mortar layer 51 is first laid on top of the insulation core material 4, which can effectively seal and fill the periphery of the insulation core material 4, directly covering the insulation core material 4. After covering, two layers of reinforcing mesh fabric, namely reinforcing mesh fabric I 52 and reinforcing mesh fabric II 53, are laid on the filling mortar layer 51. Then, a sealing mortar layer 54 is laid or sprayed on top of the reinforcing mesh fabric II 53. This design can improve the sealing effect and sealing stability of the insulation core material 4.

[0020] Based on the above structure, an outer mortar layer 10 is also provided on the outer side of the integrated structure exterior wall insulation board, and the integrated structure exterior wall insulation board is completely covered by the outer mortar layer 10.

[0021] To facilitate construction, the integrated structural exterior wall insulation board is also provided with several through holes 11. These through holes 11 are located on the ribs 33. Since the processing of the through holes 11 is the final step after the product is formed, to avoid deviations during drilling by the heating personnel, a marking area 12 is provided on the outer surface of the structural exterior wall insulation board. The marking area 12 corresponds to the ribs 33 between the insulation grooves 30. When processing the through holes 11, the through holes 11 are positioned on the ribs 33 to avoid damaging the integrity of the insulation core material 4.

[0022] Furthermore, those skilled in the art can also place the through hole 11 on the insulation core material 4. However, in order to minimize the area of ​​damage to the insulation core material 4, the insulation core material 4 requiring the through hole 11 is placed on a square structure of less than 40 square centimeters. This reduces the damaged area of ​​the insulation core material 4 and reduces the insulation performance to a certain extent.

[0023] In this embodiment, as Figure 5 , 6As shown in Figure 7, the insulation core material 4 consists of a sealing bag 41 and an insulation board 42. The outer surface of the sealing bag 41 is a fiberglass woven layer 411, and its inner surface is an aluminum foil layer. The aluminum foil layer is coated with thermosetting adhesive 412. The outer surface of the insulation board 42 is provided with a textured or uneven surface 421. In this embodiment, the insulation board 42 adopts an uneven surface 421 design, which can increase the contact area between the outer surface of the insulation board and the aluminum foil layer or thermosetting adhesive layer.

[0024] Those skilled in the art can also replace thermosetting adhesive 412 with PET and PE film coated on aluminum foil, which can also be thermoset under high heat.

[0025] Example 2: When this integrated structural exterior wall insulation board is used in building applications, it functions as an exterior wall insulation board, such as... Figure 8 As shown, the inner wall formwork 7 and the integrated external wall insulation board of the outer wall are pulled together by the tie bar 8. The tie bar 8 is pulled together by passing through the through hole 11. After being pulled and fixed, commercial concrete is poured into the area of ​​the steel cage 6. After the wall is fixed, the inner wall formwork 7 is removed. The integrated external wall insulation board on the outer wall is fixed to the wall as a whole. This structure can ensure that the integrated external wall insulation board will not fall off after long-term use.

[0026] The integrated structural exterior wall insulation board disclosed in this invention requires an overall thickness of only about 5cm. While meeting the province's 83% energy-saving requirement, it also increases the usable floor area ratio for homebuyers, reduces the shared area, and lowers the floor area ratio. Furthermore, because this product is a wrapped type, with an internal insulation core material 4 featuring a vacuum insulation structure and a thermal conductivity as low as 0.005-0.008, it offers superior insulation performance. The product also boasts a Class A fire resistance rating, allowing for a reduction in the thickness of the exterior wall plaster. The product dimensions are fully detailed according to the drawings before delivery to the construction site, enabling zero-cutting and improving construction efficiency.
