Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation boards, and in particular to an external wall thermal insulation board and a construction method thereof. Background Art

[0002] External wall insulation board is a building material used for external wall insulation. It is usually a plate-shaped product made of polystyrene, polyurethane, rock wool or glass wool. It can effectively reduce the heat loss of the building, improve the insulation performance of the building, and reduce energy consumption. External wall insulation board can also improve the fire resistance and wind pressure resistance of the building. In construction, external wall insulation board is usually fixed on the surface of the building's exterior wall to play a role in thermal insulation.

[0003] Reference is made to a Chinese patent document with authorization announcement number CN222314689U, which discloses a mesh-column multi-layer composite repair wall block for old exterior walls, which includes a composite cement layer one, a steel mesh is arranged on the outer wall of the composite cement layer one, a composite cement layer two is installed on the outer wall of the steel mesh, an insulation structure is arranged on the outer wall of the composite cement layer two, a compression plate is arranged on the outer wall of the insulation structure, a decorative coating is arranged on the outer wall of the compression plate, a waterproof layer is arranged on the outer wall of the decorative coating, four screw sleeves are respectively arranged at the four corners inside the composite cement layer one, the steel mesh, and the composite cement layer two, and one end of the fixed column is installed inside the screw sleeve.

[0004] With regard to the above-mentioned related technologies, when the insulation boards are laid, the insulation boards are spliced ​​independently and unrelated to each other. Their installation is relatively independent, which makes the connection between the insulation boards loose and unable to form a whole, easily leading to small gaps between the insulation boards, and the independent insulation boards are easy to fall off from the exterior wall under the action of external force, causing danger. Summary of the invention

[0005] In view of this, the present invention provides an exterior wall insulation board and a construction method thereof, aiming to solve the problem of unstable connection when the insulation board is laid.

[0006] To solve the above technical problems, in a first aspect, the present invention provides an exterior wall insulation board, comprising a connecting layer connected to the exterior wall, wherein the side of the connecting layer away from the exterior wall is fixedly connected to an insulation layer, the top surface of the insulation layer is higher than the top surface of the connecting layer, and the insulation layer is offset to the right relative to the connecting layer; the side of the insulation layer away from the connecting layer is slidably connected to a decorative layer, the side of the decorative layer close to the insulation layer is fixedly connected to a slider, the insulation layer is provided with an L-shaped groove for the slider to slide, and the decorative layer can slide to the lower left of the insulation layer relative to the insulation layer.

[0007] By adopting the above technical scheme, the connecting layer and the insulation layer of the insulation board are staggered, and when the insulation board is laid, the insulation layer of the insulation board can press the connecting layer of the adjacent insulation board. On the basis of the adhesive, the insulation boards can be connected more tightly by pressing each other. At the same time, the sliding of the decorative layer can make the decorative layer press the insulation layer of the adjacent insulation board, thereby further making the connection between the insulation boards more stable and reducing the probability of danger caused by the insulation board falling off. Moreover, the decorative layer is arranged on the outside and does not need to be processed again after laying, thereby reducing the work intensity of the staff and being conducive to improving work efficiency. At the same time, the decorative layer can cover the anchor nails, thereby protecting the anchor nails, extending the service life of the insulation board and reducing the probability of danger caused by the insulation board falling off.

[0008] Optionally, the insulation layer is a rectangular plate, and casting grooves are provided on all four sides of the insulation layer.

[0009] By adopting the above technical scheme, casting grooves are opened around the insulation layer. After the insulation board is laid, the casting grooves are filled with polyether foam glue, polyurethane foam glue or foam glue, so that the connection between adjacent insulation layers is more stable, and the connection between the insulation boards is further stabilized.

[0010] Optionally, a limit block fixedly connected to the connecting layer is provided at the end of the horizontal slide groove of the L-shaped slide groove, and a slot engaged with the limit block is provided on the sliding block.

[0011] By adopting the above technical solution, after the decorative layer has finished sliding, the limit block in the L-shaped slide groove is inserted into the groove on the slide block, thereby reducing the probability of movement of the decorative layer, facilitating subsequent installation and stability between the insulation boards.

[0012] Optionally, a fixing groove connected to the casting groove is provided on a side of the decorative layer close to the thermal insulation layer.

[0013] By adopting the above technical solution, the fixed groove will move with the decorative layer after the decorative layer slides, and the fixed groove will be connected with the casting groove after movement. When the casting groove is filled with foam glue, the foam glue will enter the fixed groove, and on the basis of the limit block and the card groove, the connection between the decorative layer and the insulation layer will be tighter, thereby making the connection between the insulation boards more stable.

[0014] Optionally, the fixing groove is a dovetail groove.

[0015] By adopting the above technical solution, setting the fixing groove as a dovetail groove is beneficial to improving the stability and bearing capacity of the insulation board and reducing the probability of danger caused by the insulation board falling off.

[0016] Optionally, the L-shaped sliding groove, the sliding block, the limiting block and the card slot are all provided in plurality.

[0017] By adopting the above technical solution, the L-shaped slide groove, the slider, the limit block and the card slot are all provided in multiple numbers, which is beneficial to improving the stability, safety and service life of the structure.

[0018] In a second aspect, the present invention provides a method for laying an exterior wall insulation board, which is applied to an exterior wall insulation board in the first aspect, and the method is: S1, firstly bond the support strip to the bottom of the exterior wall for support, then insert the connection layer onto the support strip, and drive anchor nails at the joint between the support strip and the connection layer, then lay the insulation board, after laying one layer, slide the decorative layer to slide it above the support strip, and press the insulation layer and the support strip; S2, then pouring foam glue into the casting trough, and the foam glue flows in the casting trough and the fixing trough; S3, inserting the connecting layer into the gap between the lower insulation layer and the connecting layer, then driving anchor nails into the joints between the connecting layer and the insulation layer, and repeatedly injecting glue to achieve fixation; S4, repeat the above process to paste the insulation board, and fill the gaps on both sides by cutting the insulation board, and finally seal the top with a sealing strip to make it flat.

[0019] By adopting the above technical solution, when laying the insulation board, the connection layer, the insulation layer and the decorative layer are pressed together to make the connection more stable. If the wall surface is uneven, the decorative layer can slide downward and then to the left to facilitate the decorative layer to cross the height difference caused by the uneven wall surface.

[0020] Optionally, the insulation boards are laid with staggered seams in the vertical direction.

[0021] By adopting the above technical solution and laying the insulation boards with staggered seams, the structural stability thereof is improved.

[0022] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The connection layer and the insulation layer of the insulation board are staggered. When laying the insulation board, the insulation layer of the insulation board can press the connection layer of the adjacent insulation board. On the basis of the adhesive, the insulation boards can be pressed against each other to make the connection between the insulation boards tighter. At the same time, the sliding of the decorative layer can make the decorative layer press against the insulation layers of the four adjacent insulation boards, thereby further making the connection between the insulation boards more stable and reducing the probability of danger caused by the insulation board falling off. By directly sticking the insulation board to the exterior wall, the construction steps can be reduced and the work efficiency can be improved. 2. After the insulation board is laid, the pouring groove is filled with polyether foam glue, polyurethane foam glue or foam glue, so that the connection between adjacent insulation layers is more stable, and the connection between insulation boards is more stable; 3. On the basis of the limit block and the slot, glue is poured into the fixing slot to make the connection between the decorative layer and the insulation layer tighter, and thus make the connection between the insulation boards more stable; 4. The decorative layer is arranged on the outside and connected to the insulation layer. There is no need to transport the decorative layer to paste it on the insulation layer, which reduces the work intensity of the staff and is conducive to improving work efficiency. At the same time, the decorative layer can cover the anchor nails, thereby protecting the anchor nails, extending the service life of the insulation board and reducing the probability of danger caused by the insulation board falling off.

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0026] In a first aspect, the present invention provides an exterior wall insulation board, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an exterior wall insulation board, comprising a connection layer 1 connected to the exterior wall, an insulation layer 2 and a decorative layer 3, wherein the cross-sectional areas of the connection layer 1, the insulation layer 2 and the decorative layer 3 are equal; the insulation layer 2 is fixedly connected to the side of the connection layer 1 away from the exterior wall, the top wall of the insulation layer 2 is higher than the top wall of the connection layer 1, and the insulation layer 2 is offset to the right relative to the connection layer 1, the decorative layer 3 is slidably connected to the side of the insulation layer 2 away from the connection layer 1, and the decorative layer 3 can move downward and then move to the left, and the insulation layer 2 is provided with casting grooves 6 on the four sides of the upper, lower, left and right sides. After the insulation board is laid, the casting grooves 6 are The casting groove 6 is filled with polyether foam glue, polyurethane foam glue or foam glue, so that the connection between the adjacent insulation layers 2 is more stable. The casting groove 6 is set as a quarter arc groove. When two adjacent insulation boards are clamped together with the insulation layer 2 through the connecting layer 1, the two casting grooves 6 close to each other are connected to form a half arc groove. A dovetail fixing groove 9 connected to the casting groove 6 is opened on the side of the decorative layer 3 close to the insulation layer 2. Setting the fixing groove 9 as a dovetail groove is conducive to improving the stability and bearing capacity of the insulation board. The length of the fixing groove 9 is equal to the length of the decorative layer 3. Among them, the connecting layer 1 is set as a board such as an XPS board or a phenolic foam insulation board. By applying an adhesive on the connecting layer 1, the insulation board can be attached to the exterior wall.

[0027] By staggering the connecting layer 1 and the insulating layer 2, the insulating layer 2 of the insulating board can press the connecting layer 1 of the adjacent insulating board when laying the insulating board. On the basis of the adhesive, the insulating boards can be connected more tightly by pressing each other. At the same time, the sliding of the decorative layer 3 can make the decorative layer 3 press the insulating layer 2 of the adjacent insulating board, thereby further making the connection between the insulating boards more stable and reducing the probability of the insulating board falling off and causing danger. Moreover, the decorative layer 3 is arranged on the outside and does not need to be processed again after laying, thereby reducing the work intensity of the staff and being conducive to improving work efficiency. At the same time, the decorative layer 3 can shield the anchor nails, thereby protecting the anchor nails, extending the service life of the insulating board and reducing the probability of the insulating board falling off and causing danger.

[0028] Reference Figure 5 and Figure 6 A slider 4 is fixedly connected to one side of the decorative layer 3 close to the insulation layer 2. An L-shaped slide groove 5 is provided on the insulation layer 2 for the slider 4 to slide. A limit block 7 fixedly connected to the connecting layer 1 is provided at the end of the transverse groove of the L-shaped slide groove 5. A slot 8 engaged with the limit block 7 is respectively provided on each slider 4.

[0029] When it is necessary to slide the decorative layer 3, first slide the decorative layer 3 downward, then slide the decorative layer 3 to the left. After sliding, the decorative layer 3 is limited by the limit block 7 and the slot 8, thereby reducing the probability of sliding of the decorative layer 3 to facilitate the laying of the insulation board.

[0030] Reference Figure 7 and Figure 8 After multiple insulation boards are laid, an insulation wall is formed. A support strip 11 is provided on the bottom back of the insulation wall. A gap is left between the top of the support strip 11 and the outer wall to facilitate the insertion of the connecting layer 1. A sealing strip 12 is provided on the top of the insulation wall to keep the top of the insulation wall flush, and the outer surface of the top of the insulation wall is completed by cutting the decorative layer 3. The insulation boards need to be laid with staggered seams, so the laying of the insulation boards will produce gaps on both sides, so the insulation boards need to be cut to complete the gaps.

[0031] The implementation principle of an exterior wall insulation board is as follows: the insulation layer 2 is offset to the upper right relative to the connecting layer 1, so that the insulation board can be pressed against the connecting layer 1 by the insulation layer 2 during laying so that the insulation boards are tightly connected, and then the connecting layer 1 is bonded to the exterior wall, and then the decorative layer 3 is slid downward and then slid to the left. During laying, the insulation board is cut and pasted to the bottom of the exterior wall. After the bottom layer is laid, the insulation board is cut according to the gap generated to fill the gap, and the casting groove 6 is filled with glue when pasting to the second insulation board of the upper layer.

[0032] In a second aspect, the present invention provides a construction method of an external wall insulation board, which is applied to an external wall insulation board in the first aspect, and the method is: S1, first glue the support bar 11 to the bottom of the exterior wall for support, then insert the connecting layer 1 onto the support bar 11, and drive anchor nails at the joint between the support bar 11 and the connecting layer 1, then lay the insulation board, after laying one layer, slide the decorative layer 3 to slide it above the support bar 11, and press the insulation layer 2 and the support bar 11; S2, then pour the foam glue into the casting groove 6, and the foam glue flows in the casting groove 6 and the fixing groove 9; S3, inserting the connecting layer 1 into the gap between the lower insulating layer 2 and the connecting layer 1, then driving anchor nails into the joint of the connecting layer 1 and the insulating layer 2, and repeatedly injecting glue to achieve fixation; S4, repeat the above process to paste the insulation board, and fill the gaps on both sides by cutting the insulation board, and finally seal the top with a sealing strip 12 to make it flat.

[0033] Wherein, in step S1: the insulation boards are laid with staggered seams in the vertical direction.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
