Technical Field

[0001] This utility model relates to the field of insulation board technology, and in particular to an XPS extruded insulation board. Background Technology

[0002] XPS extruded polystyrene insulation board is a rigid foam plastic board made of polystyrene resin as the main raw material, with the addition of catalysts, and is produced by heating and extruding through a special process. Due to its extremely low thermal conductivity, it can effectively prevent heat transfer and is widely used in the external wall insulation structure of various buildings. It can effectively improve the thermal insulation performance of buildings and improve indoor thermal comfort.

[0003] In the prior art, such as the Chinese patent CN215253587U "An XPS Extruded Insulation Board for External Walls", this utility model provides protruding insertion holes on the side of the insulation board and matching grooves on the opposite side. After two insulation boards are inserted and bonded, the lateral and longitudinal bonding forces between adjacent insulation boards on the same side are enhanced, preventing the adjacent insulation boards from shifting after long-term use.

[0004] The existing XPS extruded insulation board only uses a slot and groove on one side of the insulation board to lock together, which restricts the connection between the left and right XPS extruded insulation boards. This can easily lead to unstable connection between the XPS extruded insulation boards, and the upper and lower XPS extruded insulation boards may still become misaligned after long-term use, thus affecting the insulation effect of the device. Utility Model Content

[0005] To overcome the problem that in the use of XPS extruded insulation boards, the connection between the left and right XPS extruded insulation boards is restricted by the interlocking and groove on one side of the insulation board, which easily leads to unstable connection between the XPS extruded insulation boards and misalignment of the upper and lower XPS extruded insulation boards after long-term use, thus affecting the insulation effect of the device.

[0006] The technical solution of this utility model is as follows: an XPS extruded insulation board, comprising an XPS insulation board, wherein sealed air cavities are distributed equidistantly and alternately inside the XPS insulation board, a tenon groove is provided on the outer side of the frame of the XPS insulation board, and a tenon is provided on the outer side of the frame of the XPS insulation board, the tenon being integrally connected to the XPS insulation board, and the tenon and the tenon groove being distributed equidistantly and alternately on the outer side of the frame of the XPS insulation board.

[0007] Preferably, one side of the XPS insulation board is coated with an intumescent fire-retardant coating, and the other side of the XPS insulation board is coated with an inorganic fire-retardant coating.

[0008] Preferably, the outer surface of the intumescent fireproof coating is coated with a polyurethane waterproof coating, and the outer surface of the inorganic fireproof coating is provided with an installation base plate, which is bonded to the inorganic fireproof coating.

[0009] Preferably, the mounting base plate has a groove on the side away from the inorganic fireproof coating, and the grooves are evenly distributed on the mounting base plate.

[0010] Preferably, an L-shaped limiting buckle is fixedly connected to the outer surface of the polyurethane waterproof coating, and limiting grooves are formed on the inner sides of both ends of the L-shaped limiting buckle.

[0011] Preferably, the outer side of the L-shaped limiting buckle is slidably connected to a limiting seat, and the limiting seat is engaged with the limiting groove.

[0012] Preferably, the top surface of the limiting card seat is provided with a connecting groove, the connecting groove is interconnected with the XPS insulation board and the mounting base plate, and a fixing bolt is slidably connected to the inner side of the connecting groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. During the installation of XPS insulation boards, by aligning the tenon and groove on one side of the XPS insulation board with the tenon and groove on the other side of the XPS insulation board, the two sets of insulation boards can be quickly and tightly fitted together. After assembling and connecting the two sets of insulation boards, the two sets of L-shaped limiting buckles are fitted together. By inserting the limiting brackets into the limiting grooves on both sides, the assembled insulation boards can be limited by the two sets of L-shaped limiting buckles. After combining the four sets of insulation boards, the four sets of connecting grooves are fitted together to form a complete connecting hole. By inserting the fixing bolts into the connecting hole and threading them to the wall, the entire XPS extruded insulation board is fitted and fixed to the wall, preventing the edges of the XPS extruded insulation board from lifting and increasing the stability of the XPS extruded insulation board installation.

[0015] 2. By interlocking multiple sets of XPS extruded insulation boards to form a stable overall structure, the stability of the insulation board connection is maintained. After assembly, the connection between the multiple sets of XPS extruded insulation boards is limited, so that each set of XPS extruded insulation boards can form a stable connection with the surrounding insulation boards, which enhances the stability of the overall structure and prevents the two sets of XPS extruded insulation boards from misaligning and falling off.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides an embodiment: an XPS extruded insulation board, including an XPS insulation board 1, with sealed air chambers 201 distributed equidistantly and alternately inside the XPS insulation board 1, a tenon groove 202 provided on the outer side of the frame of the XPS insulation board 1, and a tenon 203 provided on the outer side of the frame of the XPS insulation board 1, the tenon 203 being integrally connected to the XPS insulation board 1, and the tenon 203 and the tenon groove 202 being distributed equidistantly and alternately on the outer side of the frame of the XPS insulation board 1.

[0024] One side of the XPS insulation board 1 is coated with an intumescent fire-retardant coating 301, and the other side is coated with an inorganic fire-retardant coating 302. The intumescent fire-retardant coating 301 can expand when heated, thereby forming a thick foam-like carbonized layer with good heat insulation properties, which can prevent flames from directly contacting the insulation board. The inorganic fire-retardant coating 302 can form a hard fire-retardant layer through a chemical reaction, which can play the role of heat insulation and preventing the spread of flames. The fire-retardant coatings on the inner and outer sides of the XPS insulation board 1 can prevent heat from being transferred to the interior of the insulation board, slow down the heating rate of the insulation board, prevent the XPS insulation board 1 from melting due to high temperature, and delay the spread of fire.

[0025] The outer surface of the intumescent fireproof coating 301 is coated with a polyurethane waterproof coating 303, and the outer surface of the inorganic fireproof coating 302 is provided with an installation base plate 304. The installation base plate 304 is bonded to the inorganic fireproof coating 302. The polyurethane waterproof coating 303 can form a dense waterproof membrane on the surface of the insulation board, preventing moisture from penetrating into the interior of the XPS insulation board 1 and affecting its insulation performance. The installation base plate 304 can bring the entire insulation board into contact with the wall, thereby facilitating the connection and fixation of the insulation board to the wall.

[0026] A groove 305 is provided on the side of the mounting base plate 304 away from the inorganic fireproof coating 302, and the grooves 305 are evenly distributed on the mounting base plate 304. In high humidity and strong wind environments, the grooves 305 at the bottom of the mounting base plate 304 increase the contact area between the insulation board and the wall, allowing the adhesive to fill into the grooves 305, increasing the bonding area, thereby enhancing the adhesion between the insulation board and the base layer and preventing the insulation board from loosening due to environmental factors.

[0027] The outer surface of the polyurethane waterproof coating 303 is fixedly connected with an L-shaped limiting buckle 401. The inner sides of both ends of the L-shaped limiting buckle 401 are provided with limiting grooves 402. After the two sets of insulation boards are assembled and connected, the two sets of L-shaped limiting buckles 401 are made to fit together, so that the insulation boards are limited by the limiting grooves 402 on the outer sides of the two sets of L-shaped limiting buckles 401, preventing the two sets of insulation boards from misaligning and falling off.

[0028] The outer side of the L-shaped limiting buckle 401 is slidably connected to the limiting seat 403. The limiting seat 403 is engaged with the limiting groove 402. After the two sets of insulation boards are engaged, the two sets of L-shaped limiting buckles 401 can be connected and restricted by inserting the limiting seat 403 into the limiting groove 402, so that each set of insulation boards can form a stable connection with the surrounding insulation boards, thereby enhancing the stability of the overall structure.

[0029] The top surface of the limiting bracket 403 is provided with a connecting groove 404, which is interconnected with the XPS insulation board 1 and the mounting base plate 304. A fixing bolt 405 is slidably connected to the inner side of the connecting groove 404. After the four sets of insulation boards are combined and connected, the four sets of connecting grooves 404 are fitted together to form a complete connecting hole. By inserting the fixing bolt 405 into the connecting hole and threadedly connecting it to the wall, the entire insulation board is fitted and fixed to the wall, preventing the edges of the insulation board from lifting.

[0030] Working principle: According to Figures 1-5As shown, the gas inside the sealed air cavities 201 that are evenly distributed inside the XPS insulation board 1 can hinder the conduction of heat, making heat transfer difficult, thereby playing a heat insulation role. In addition, multiple sealed air cavities 201 can reduce the density of the material, thereby further reducing the efficiency of heat transfer.

[0031] During installation, by engaging the tenon 202 and tenon 203 on one side of XPS insulation board 1 with the tenon 202 and tenon 203 on the other side of another set of XPS insulation board 1, the two sets of insulation boards can be quickly and tightly fitted together to form a stable overall structure and maintain the stability of the insulation board connection.

[0032] After assembling and connecting the two sets of insulation boards, the two sets of L-shaped limiting buckles 401 are fitted together. By inserting the limiting brackets 403 into the limiting grooves 402 on both sides, the two sets of L-shaped limiting buckles 401 can limit the assembled insulation boards, so that each set of insulation boards can form a stable connection with the surrounding insulation boards, which enhances the stability of the overall structure and prevents the two sets of insulation boards from misaligning and falling off.

[0033] After the four sets of insulation boards are combined and connected, the four sets of connecting grooves 404 are fitted together to form a complete connecting hole. The fixing bolts 405 are then inserted into the connecting hole and threadedly connected to the wall to fix the insulation board, thereby fixing the entire insulation board to the wall surface, preventing the edges of the insulation board from lifting, and increasing the stability of the insulation board installation.

[0034] The fireproof coating on both the inner and outer sides of XPS insulation board 1 can prevent heat from being transferred into the insulation board, slow down the heating rate of the insulation board, prevent the XPS insulation board 1 from melting due to high temperature, and delay the spread of fire. The polyurethane waterproof coating 303 can form a dense waterproof film on the surface of the insulation board, preventing moisture from penetrating into the interior of XPS insulation board 1 and affecting its insulation performance.

[0035] In environments with high humidity and strong winds, the groove 305 at the bottom of the base plate 304 can increase the contact area between the insulation board and the wall, allowing the adhesive to fill the groove 305, increasing the bonding area of ​​the insulation board, thereby enhancing the adhesion between the insulation board and the base layer and preventing the insulation board from loosening due to environmental factors.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
