Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boards, in particular to an anti-leakage thermal insulation board for building exterior walls. Background Art

[0002] For building walls made of reinforced concrete as the main body, the thermal conductivity is relatively large, so the thermal insulation performance of traditional building walls is not particularly good. In order to reduce the heat exchange between indoors and outdoors, especially during winter heating and summer cooling, it is currently common to install insulation boards on the exterior walls of buildings. The low thermal conductivity of the insulation boards can not only effectively reduce the heat exchange between indoors and outdoors, but also play a role in sound insulation and noise reduction. In addition, the current insulation boards can also play a good decorative effect by setting various colors and patterns on the outermost decorative panels.

[0003] For insulation boards installed on the exterior walls of buildings, water leakage should be prevented at the joints between the insulation boards, especially in some rainy areas, where rainwater can easily penetrate the joints and enter the wall, which not only easily causes mold inside the insulation board, but also causes the metal parts used to fix the insulation board to rust, and eventually causes the insulation board to fall off, causing safety problems. However, the current insulation boards generally adopt the method of simply docking and then sealing the external joints with glue. The problem with this method is that the sealant is prone to aging, breaking, and falling off after a period of wind and sun exposure, resulting in sealing failure. After encountering rain, it is easy for the insulation boards to leak again. Utility Model Content

[0004] In view of the above problems, the utility model provides an anti-leakage building exterior wall insulation board, which can not only seal the joints to prevent leakage, but also effectively prevent the aging of the sealant and increase the effective service life of the insulation board. Specifically, the technical solution of the utility model is as follows.

[0005] A leakage-proof building exterior wall insulation board, comprising: a decorative panel, an insulating panel, a flame retardant panel, an insulation board and a bottom plate. Wherein: the insulation board is fixed to the back of the vertically arranged decorative panel, the flame retardant panel is fixed to the back of the insulation board, the insulation board is fixed to the back of the flame retardant panel, and the bottom plate is fixed to the back of the insulation board. The top and right ends of the insulation board are telescoped inward to form a groove, and the lower and left ends of the insulation board are extended outward to form a raised strip, and the depth of the groove is greater than the protruding length of the raised strip. An installation groove is provided on the top surface of the insulation board, and the installation groove is located in the area where the flame retardant panel, the insulation board and the bottom plate are located. One port of the installation groove is connected to the groove, and the other port is located on the back of the bottom plate.

[0006] Furthermore, there is also a heat preservation board fixing part, which includes a horizontal plate, a connecting plate and a vertical plate. The horizontal plate is arranged horizontally, and the connecting plate is an inverted "L"-shaped plate body, the lower end of which is fixedly connected to the middle edge of the horizontal plate, and the upper end is fixedly connected to the middle of the lower end surface of the vertical plate, and the horizontal plate has a first mounting hole, and the vertical plate has a second mounting hole.

[0007] Furthermore, the width of the transverse plate is smaller than the width of the groove, the width of the connecting plate is smaller than the width of the mounting groove, and the length of the connecting plate is greater than the length of the mounting groove.

[0008] Furthermore, the height of the transverse plate is smaller than the depth of the groove, so that the sealant can be injected into the groove.

[0009] Further, the transverse plate is located in the groove on the top of the insulating plate, and the two are fixed together by a fastener passing through the first mounting hole. The transverse part of the connecting plate is located in the mounting groove, and the vertical plate is located above the back of the bottom plate.

[0010] Furthermore, the vertical plate is fixed to the building wall by a fastener passing through the second mounting hole.

[0011] Furthermore, the decorative panel includes any one of an aluminum alloy plate, a plastic plate, and the like.

[0012] Furthermore, the insulating plate includes any one of a plastic plate, a rubber plate, a polytetrafluoroethylene plate, and the like.

[0013] Furthermore, the insulation board includes any one of a polystyrene foam board, a polyurethane foam board, a glass wool board, and the like.

[0014] Furthermore, the bottom plate includes any one of an aluminum alloy plate, a plastic plate, and the like.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects: the top and right end of the anti-leakage building exterior wall insulation board of the utility model are telescoped inward to form a groove, and the lower end and the left end are extended outward to form a raised strip, and the depth of the groove is greater than the protruding length of the raised strip. Therefore, when the insulation board is spliced, after the raised strip of the insulation board is inserted into the groove of the adjacent insulation board, a reserved gap will be formed between the two, which is convenient for injecting sealant into the gap. On the one hand, the sealant can bond the adjacent insulation boards together to improve the sealing. On the other hand, since the sealant is located inside the insulation board, it can avoid aging and failure caused by wind and sun, and improve the service life. In addition, the insulation board fixing member of the utility model can not only fix the insulation board on the building wall, but also can be integrated into the top surface structure of the insulation board, so that the insulation boards are in close contact with each other, avoiding affecting the sealing.

DETAILED DESCRIPTION

[0021] For the convenience of description, if the words "up", "down", "left" and "right" appear in the present invention, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or component needs to have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0022] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The anti-leakage building exterior wall insulation board of the present invention is now further explained in conjunction with the drawings and specific embodiments of the specification.

[0023] refer to Figure 1, an example of an anti-leakage building exterior wall insulation board is provided, comprising: a decorative panel 1, an insulating panel 2, a flame retardant panel 3, an insulating panel 4 and a bottom plate 5. Specifically: the decorative panel 1 is arranged vertically, and the insulating panel 2 is bonded and fixed to the back of the decorative panel 1. The flame retardant panel 3 is bonded and fixed to the back of the insulating panel 2, the insulating panel 4 is bonded and fixed to the back of the flame retardant panel 3, and the bottom plate 5 is bonded and fixed to the back of the insulating panel 4. Among them: the decorative panel 1 can be made of aluminum alloy plate or plastic plate, and the required pattern, color, etc. can be set on its outer surface to improve the aesthetics of the insulation board. The insulating panel 2 can be made of plastic plate, rubber plate or polytetrafluoroethylene plate, etc. The insulating panel 4 can be made of polystyrene foam board, polyurethane foam board or glass wool board, etc. The bottom plate 5 can be made of aluminum alloy plate, plastic plate, etc.

[0024] Furthermore, the top and right ends of the insulating board 2 are extended inward to form a groove 201, and the lower and left ends of the insulating board 2 are extended outward to form a raised strip 202, and the depth of the groove 201 is greater than the protruding length of the raised strip 202. When in use, the first layer of insulation boards is spliced ​​from left to right, wherein the raised strip 202 on the left end surface of the right insulation board is engaged in the groove 201 on the right end surface of the adjacent left insulation board, and because the protruding length of the raised strip 202 is less than the depth of the groove 201, a reserved gap 203 is formed between the two (refer to Figure 2 ). Therefore, after the first layer of insulation board is laid, a sealant is injected into the reserved gap 203 using a glue gun or other tool until the reserved gap 203 is completely filled.

[0025] After completion, the second layer of insulation boards are spliced ​​piece by piece from left to right on the first layer of insulation boards, wherein the raised strip 202 on the lower end surface of the second layer of insulation boards is located in the groove 201 on the upper end surface of the first layer of insulation boards, and a reserved gap is formed between the two. Therefore, when splicing the second layer of insulation boards, each time a piece is spliced, sealant is also injected into the reserved gap formed by the upper and lower insulation boards until the reserved gap 203 is completely filled. After completion, the third layer of insulation boards is installed, and this process is repeated until the laying is completed. On the one hand, the sealant can bond adjacent insulation boards together to improve the sealing. On the other hand, since the sealant is located inside the insulation board, it can avoid aging and failure caused by wind and sun, thereby improving the service life.

[0026] Continue to refer Figure 1 The top surface of the insulation board has a mounting groove 204, and the mounting groove 204 is located in the area where the flame retardant board 3, the insulation board 4 and the bottom plate 5 are located. One end of the mounting groove 204 is connected to the groove 201, and the other end is located on the back of the bottom plate 5. The mounting groove 204 is used to Figure 3 The insulation board fixing member shown in the figure cooperates to firmly fix the insulation board on the building exterior wall 12 (refer to Figure 2), at the same time, the insulation board fixing piece can also be integrated into the top surface structure of the insulation board, so that the insulation boards are in close contact with each other, avoiding affecting the sealing. Specifically, refer to Figure 3 The insulation board fixing member includes a horizontal plate 6, a connecting plate 7 and a vertical plate 8. The horizontal plate 6 is arranged horizontally, and the connecting plate 7 is an inverted "L"-shaped plate body, the lower end of which is fixedly connected to the middle edge of the horizontal plate 6, and the upper end is fixedly connected to the middle of the lower end surface of the vertical plate 8. The horizontal plate 6 has a first mounting hole 9, and the vertical plate 8 has a second mounting hole 10.

[0027] When in use, the insulation board fixing member is arranged at the upper end surface of the first layer of insulation board, wherein the horizontal plate 6 is located in the groove 201 on the upper end surface of the insulation board, and the two are fixed together by the fastener 11 passing through the first mounting hole 9. The horizontal part of the connecting plate 7 is located in the mounting groove 204, and the vertical plate 8 is located above the back of the bottom plate 5. The vertical plate 8 is fixed to the building wall 12 by the fastener 11 passing through the second mounting hole 10. It should be understood that the height of the horizontal plate 6 should be less than the depth of the groove 201, so that the sealant can be injected into the groove 201 to fill the groove 201. The above-mentioned insulation board fixing member makes full use of the groove 201 and the mounting groove 204 on the top surface of the insulation board, so that the horizontal plate 6 and the connecting plate 7 can be hidden, and can also play a role in connecting and fixing the insulation board. After installation, the insulation board fixing member will not cause additional gaps between the upper and lower adjacent insulation boards, avoiding the influence on the sealing of the insulation board. At the same time, the insulation board fixing parts will not be exposed to the outside, thus avoiding the influence on the aesthetics of the formed insulation wall.

[0028] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
