Description

Technical Field

[0001] This invention belongs to the technical field of exterior wall insulation boards, specifically relating to an integrated composite insulation board for building exterior walls. Background Technology

[0002] Exterior wall insulation boards, also known as integrated exterior wall decoration and insulation boards, are composed of boards and insulation materials. Since most insulation materials are flexible, their service life in outdoor environments is limited. Therefore, there is a composite board on the market that uses rigid boards (such as aluminum plates) as the outer shell for protection and is filled with insulation cotton and other materials to achieve the effect of insulation and long service life.

[0003] The aforementioned composite integrated panels have shortcomings. Due to the frequent occurrence of strong winds and other severe weather in the external wall environment, although the composite panels protect the insulation cotton, the internal cavities of the composite panels greatly reduce their ability to resist pressure and strong winds. Even with reinforcing ribs inside the composite panels, it is difficult for the ribs to provide tensile strength and enable the composite panels to resist wind. In addition, after the insulation cotton is in place, the back panel and front panel of the composite panels can only be closed with adhesive, and the service life of the adhesive exposed outdoors is also relatively short. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated thermal insulation composite panel for building exterior walls in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A thermal insulation composite integrated panel for building exterior walls includes a surface panel with a hollow cavity and thermal insulation cotton located inside the hollow cavity. The surface panel is welded from a back panel and a front panel. The hollow cavity is provided with a reinforcing rib assembly and a connecting assembly that connect the reinforcing back panel and the front panel.

[0007] The reinforcing rib assembly includes a reinforcing cylinder disposed on the bottom wall of the back panel and penetrating the insulation cotton. One end of the reinforcing cylinder is connected to the outside of the back panel for connecting to an external negative pressure device. The side surface of the reinforcing cylinder is provided with a negative pressure suction hole. A composite film is provided on the side of the insulation cotton facing the panel for compressing the insulation cotton under negative pressure. The inner wall of the reinforcing cylinder is also provided with a valve groove and a rubber valve block for closing the other end of the reinforcing cylinder under negative pressure.

[0008] The connecting assembly includes an adhesive plate and a docking cylinder. The adhesive plate is used for bonding the panel, and the docking cylinder is used to insert into the other end of the reinforcing cylinder and bond it. The adhesive plate has a guide hole on its surface for communicating with the docking cylinder, and the adhesive is added through the reinforcing cylinder.

[0009] As a further optimization of the present invention, the reinforcing cylinder is fixed to the back plate by sealing welding. The sealing welding connection method enables the reinforcing cylinder and the back plate to have a strong connection capability, so as to achieve the tensile and compressive strength of the reinforcing rib.

[0010] As a further optimization of the present invention, the surface of the insulation cotton is provided with a through hole for the reinforcing cylinder to pass through, and the through hole and the reinforcing cylinder are interference-fitted. In order to compress the insulation cotton during the welding process of the back plate and the front plate, a composite film is provided on the surface of the insulation cotton. The composite film is not breathable. The composite film and the insulation cotton can be compressed into the back plate as a whole by an external pressure device. A negative pressure source is connected at the opening of the reinforcing cylinder. The negative pressure source can continuously generate negative pressure to reduce the rebound of the insulation cotton, so as to facilitate the welding of the back plate and the front plate. After the welding cools down, the negative pressure is released so that the insulation cotton can rebound and fill the entire hollow cavity. Therefore, in this solution, the interference-fitted connection between the through hole and the reinforcing cylinder is used to reduce air leakage and prevent the insulation cotton from rebounding quickly.

[0011] As a further optimization of the present invention, the reinforcing cylinder is provided with a funnel groove along the glue injection direction to facilitate the adhesive entering the narrow valve groove.

[0012] As a further optimization of the present invention, the surface of the adhesive plate that contacts the panel is provided with a flow guide pattern. When the adhesive plate and the panel are pressed together, the flow guide pattern forms a gap to facilitate the flow of adhesive. After the adhesive in the gap is cured, it forms a first adhesive. The flow guide pattern can facilitate the flow of adhesive and increase the contact area, thereby improving the bonding effect.

[0013] As a further optimization of the present invention, the inner and outer walls of the docking cylinder are provided with guide strips. The guide strips on the outer wall are used for the adhesive to flow and fill between the outer wall of the docking cylinder and the inner wall of the reinforcing cylinder. After curing, a second adhesive is formed. By forming an adhesive effect between the outer wall of the docking cylinder and the inner wall of the reinforcing cylinder, good tensile strength is achieved. The guide strips facilitate the flow of adhesive.

[0014] As a further optimization of the present invention, the inside of the docking cylinder is used to accommodate the rubber valve block so that the valve groove is opened, and a gap is formed between the guide strip on the inner wall of the docking cylinder and the rubber valve block so that the adhesive can flow through the guide hole over the rubber valve block and enter the surface of the adhesive plate that contacts the panel. When the rubber valve block is in the valve groove, the valve groove is closed. Therefore, the internal space of the docking cylinder is used to accommodate the rubber valve block and is supported by the guide strip on the inner wall.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention compresses and stores the insulation cotton during the welding process of the back panel and the front panel. A composite film is applied to the surface of the insulation cotton, and a negative pressure source is connected to the opening of the reinforcing cylinder to reduce the rebound of the insulation cotton, so as to facilitate the welding of the back panel and the front panel and prevent the high temperature at the welding point from damaging the insulation cotton. Furthermore, the adhesive board is bonded to the front panel by post-application of glue. This method ensures that each adhesive board is tightly bonded to the front panel and there is no unevenness in the overall composite bonding position. Attached Figure Description

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1-7As shown, a thermal insulation composite integrated panel for building exterior walls includes a surface panel 1 with a hollow cavity and thermal insulation cotton 2 located inside. The surface panel 1 is welded together by a back panel 11 and a front panel 12. A reinforcing rib assembly 3 and a connecting assembly 4 are provided inside the hollow cavity to connect the reinforcing back panel 11 and the front panel 12.

[0028] The reinforcing rib assembly 3 includes a reinforcing cylinder 31 disposed on the bottom wall of the back plate 11 and penetrating the insulation cotton 2. One end of the reinforcing cylinder 31 is connected to the outside of the back plate 11 for connecting to an external negative pressure device. A negative pressure suction hole 32 is provided on the side surface of the reinforcing cylinder 31. A composite film 202 is provided on the side of the insulation cotton 2 facing the panel 12 for compressing the insulation cotton 2 under negative pressure. A valve groove 34 and a rubber valve block 35 are also provided on the inner wall of the reinforcing cylinder 31 for closing the other end of the reinforcing cylinder 31 under negative pressure.

[0029] The connecting component 4 includes an adhesive plate 41 and a docking cylinder 42. The adhesive plate 41 is used to bond the panel 12, and the docking cylinder 42 is used to insert into the other end of the reinforcing cylinder 31 and bond it. The adhesive plate 41 has a guide hole 44 on its surface for communicating with the docking cylinder 42, and the adhesive is added through the reinforcing cylinder 31.

[0030] This solution employs a welding connection between the back plate 11 and the front panel 12. While this method is conventional, to prevent the high temperature during welding from damaging the insulation cotton 2, this solution compresses and encloses the insulation cotton 2 during the welding process. A composite film 202 is provided on the surface of the insulation cotton 2. The composite film 202 is not breathable and can be compressed into the back plate 11 as a whole by an external pressure device. A negative pressure source is connected to the opening of the reinforcing cylinder 31. The negative pressure source can continuously generate negative pressure and transmit it into the insulation cotton 2 through the negative pressure suction hole 32 to reduce the rebound of the insulation cotton 2, so as to facilitate the welding of the back plate 11 and the front panel 12. After the welding cools down, the negative pressure is released so that the insulation cotton 2 can rebound and fill the entire hollow cavity.

[0031] Furthermore, the bonding plate 41 and the panel 12 are bonded using a post-application method. The conventional bonding method involves applying adhesive to the surface of the bonding plate 41 and then directly bonding the panel 12 to the bonding plate 41. However, not all bonding plates 41 may be on the same plane, and there will inevitably be cases of loose bonding during the bonding process. This solution uses a post-application method. After the panel 12 and the back plate 11 are welded, the back plate 11 is placed facing upwards, and the connecting component 4 falls naturally to fit against the panel 11. Then, liquid adhesive is injected to allow the liquid adhesive to flow into the contact surface between the bonding plate 41 and the panel 12. Excess adhesive flows into the outer wall of the mating cylinder 42, making the mating cylinder 42 and the reinforcing cylinder 31 tightly bonded. This method ensures that each bonding plate 41 is tightly bonded to the panel 12, and there will be no unevenness in the overall bonding position. Pressure injection can be used if necessary during the injection process.

[0032] The reinforcing cylinder 31 is fixed to the back plate 11 by sealing welding. The sealing welding connection method enables the reinforcing cylinder 31 and the back plate 11 to have a strong connection, so as to achieve the tensile and compressive strength of the reinforcing rib.

[0033] The surface of the insulation cotton 2 is provided with a through hole 201 for the reinforcing cylinder 31 to pass through, and the through hole 201 and the reinforcing cylinder 31 are interference-fitted. In this solution, the interference-fitted connection between the through hole 201 and the reinforcing cylinder 31 is used to reduce air leakage and prevent the insulation cotton 2 from rebounding rapidly during compression.

[0034] The reinforcing cylinder 31 is provided with a funnel groove 33 along the glue injection direction to facilitate the adhesive entering the narrow valve groove 34.

[0035] The adhesive plate 41 has a flow guide pattern 43 on the surface that contacts the panel 12. The flow guide pattern 43 forms a gap when the adhesive plate 41 and the panel 12 are pressed together to facilitate the flow of adhesive. After the adhesive in the gap is cured, it forms the first adhesive 46. The flow guide pattern 43 can facilitate the flow of adhesive, and the rough and uneven texture can increase the contact area and improve the bonding effect.

[0036] Both the inner and outer walls of the docking cylinder 42 are provided with guide strips 45. The guide strips 45 on the outer wall are used for the adhesive to flow and fill between the outer wall of the docking cylinder 42 and the inner wall of the reinforcing cylinder 31. After curing, a second adhesive 47 is formed. By forming an adhesive effect between the outer wall of the docking cylinder 42 and the inner wall of the reinforcing cylinder 31, good tensile strength is achieved. The guide strips 45 facilitate the flow of adhesive.

[0037] The interior of the docking cylinder 42 is used to accommodate the rubber valve block 35 so that the valve groove 34 can be opened. A gap is formed between the guide strip 45 on the inner wall of the docking cylinder 42 and the rubber valve block 35 so that the adhesive can flow through the guide hole 44 over the rubber valve block 35 and enter the surface of the adhesive plate 41 that contacts the panel 12. When the rubber valve block 35 is under negative pressure, it is in the valve groove 34, so that the valve groove 34 is closed. Therefore, the interior space of the docking cylinder 42 is used to accommodate the rubber valve block 35 during adhesive injection and is supported by the guide strip 45 on the inner wall.

[0038] The specific implementation method is as follows: First, the insulation cotton 2 is placed inside the back plate 11, and the insulation cotton 2 is compressed using an external machine or manually. Then, the reinforcing cylinder 31 is connected to an external negative pressure device to generate a continuous negative pressure to hold the insulation cotton 2 in place. The connecting component 4 is inserted into the reinforcing cylinder 31, and the panel 12 is covered on top. The negative pressure is maintained, and the panel 12 is welded to the back plate 11 to form a whole. After cooling, the negative pressure is released, allowing the insulation cotton 2 to rebound and fill the hollow cavity. The back plate 11 is placed facing upwards, the reinforcing cylinder 31 is vertical, and the rubber valve block 35 falls from the valve groove 34 into the docking cylinder 42. Adhesive is injected into the reinforcing cylinder 31. The adhesive flows from top to bottom into the funnel groove 33, valve groove 34, the inside of the docking cylinder 42, and the guide hole 44, and finally enters the guide pattern 43. After curing to form the first adhesive 46, the adhesive is injected again. Excess adhesive overflows from the docking cylinder 42 and flows down into the gaps of the guide strips 45 around the docking cylinder 42. After curing, the second adhesive 47 is formed, and the production is completed. Then, the back plate 11 is fixed to the outer wall by the connector 13 set on the back plate 11, and the installation is completed. During installation, the opening of the reinforcing cylinder 31 can face the wall without affecting the aesthetics, or it can be sealed.

[0039] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
