Description

Technical Field

[0001] The utility model relates to the technical field of insulation boards, in particular to an exterior wall insulation board for buildings. Background Art

[0002] The insulation board is made of polystyrene resin as the raw material plus other raw and auxiliary materials and polymers, and the plastic board has moisture-proof and waterproof properties. It can reduce the thickness of the building's exterior envelope structure, thereby increasing the indoor usable area. With the improvement of the requirements for building insulation, insulation boards are installed and laid on the exterior wall during construction.

[0003] During the construction of the insulation board, the insulation board is connected to the wall by applying mortar on one side of the insulation board, and then the position of the insulation board is fixed by using stud bolts at the four corners of the insulation board. Then, a plurality of insulation boards are bonded by an adhesive. Since the stud bolt is not directly connected to the insulation board, the insulation board may tilt and fall to the side away from the wall after the effect of the adhesive becomes poor. When installing the insulation board by passing the stud bolt through the insulation board, due to the destructibility of the material of the insulation board, the connection between the stud bolt and the insulation board may rot over a long time, and then the insulation board becomes loose and falls, resulting in the problem of low practicability when the insulation board is used. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that due to the lack of direct connection between the stud bolt and the insulation board, the insulation board may tilt and fall to the side away from the wall after the effect of the adhesive becomes poor. When installing the insulation board by passing the stud bolt through the insulation board, due to the destructibility of the material of the insulation board, the connection between the stud bolt and the insulation board may rot over a long time, and then the insulation board becomes loose and falls, resulting in the problem of low practicability when the insulation board is used, and to propose an exterior wall insulation board for buildings.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An exterior wall insulation board for buildings, including a board body, a fastening device is arranged inside the board body, the fastening device includes a plurality of groove cylinders, a plurality of through holes are opened on the outer surface of the board body, a circular groove is opened on the inner wall of the through hole, the groove cylinder is located inside the circular groove, an annular groove is opened inside the groove cylinder, a plurality of round rods are fixedly connected to the inner wall of the annular groove, one end of the round rod is fixedly connected with a sector plate, and a spring is arranged on the outer surface of the round rod, and two ends of the spring are respectively fixedly connected with one side of the round rod and one side of the inner wall of the annular groove.

[0006] The effects achieved by the above components are as follows: By setting the grooved drum, when installing the heat preservation board, connecting workpieces such as stud bolts can pass through the through holes on the outer surface of the board body and be connected to the wall surface. When the stud bolt passes through the inside of the grooved drum and contacts one side of the sector plate, it will push the round rod to slide into the annular groove and compress the spring. The elastic force of the spring pushes the sector plate to limit the position of the stud bolt inside the grooved drum, as much as possible to avoid damaging the inside of the board body when connecting the board body to the wall surface with the stud bolt, and further limit the position between the stud bolt and the board body, improving the stability of the board body after installation.

[0007] Preferably, the inner diameter of the spring is slightly larger than the diameter of the round rod, and the round rod is located inside the spring.

[0008] The effects achieved by the above components are as follows: When the spring is compressed, it will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring, as much as possible to avoid the spring being distorted.

[0009] Preferably, convex strips are fixedly connected to the top and bottom edges of the sector plate, and the convex strips are rubber strips made of rubber.

[0010] The effects achieved by the above components are as follows: By setting the convex strips made of rubber, the friction at the contact between the stud bolt and the top and bottom of the sector plate can be increased, making it difficult for the stud bolt to slide inside the grooved drum.

[0011] Preferably, a plurality of positioning rods are fixedly connected to the inner wall of the annular groove, and the two positioning rods are respectively located on the upper and lower sides of the spring.

[0014] The effects achieved by the above components are as follows: When one end of the rubber convex block abuts against the inner wall of the annular groove when the round rod moves into the annular groove, the rubber convex block can buffer the contact between the round rod and the inner wall of the annular groove, as much as possible to avoid the round rod and the spring being unable to function properly due to excessive force when the sector plate is squeezed.

[0015] Preferably, a protective device is provided on the outer surface of the board body. The protective device includes two elastic plates, a mesh plate is fixedly connected to the side where the two elastic plates are close to each other, and clamping grooves are provided on both sides of the board body.

[0016] The effects achieved by the above components are as follows: When installing the insulation board, the two elastic plates can be bent outward at a certain angle, and then the tops of the two elastic plates are clamped at the card slots on the outer surface of the board body. The elastic plates and the mesh board are installed on one side of the board body. Through the mesh board, the surface structure on the outside of the board body can be further strengthened, and it is possible to avoid as much as possible the partial peeling of the surface of the board body after long-term use.

[0017] Preferably, two reinforcing rods are fixedly connected to the bottom end of the mesh board, and the two ends of the two reinforcing rods are respectively fixedly connected to the two diagonal corners of the mesh board.

[0019] Preferably, a convex piece is fixedly connected to one side of the elastic plate, and the convex piece is a rubber sheet made of rubber material.

[0020] The effects achieved by the above components are as follows: After the protection device is installed on the outer surface of the board body, it is more convenient to pull the elastic plate to deform by pinching the outer surface of the rubber convex piece, and the elastic plate and the mesh board can be removed for replacement.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0022] In the present utility model, by setting the fastening device, the stud is passed through the inside of the groove cylinder to be connected to the wall surface, so as to avoid as much as possible the damage to the inside of the board body caused by the stud.

[0029] Example 1, as Figures 1-4 shown, an exterior wall thermal insulation board for buildings includes a plate body 1. A fastening device 2 is arranged inside the plate body 1. The fastening device 2 includes a number of groove cylinders 23. A number of through holes 21 are formed on the outer surface of the plate body 1. A circular groove 22 is formed on the inner wall of the through hole 21. The groove cylinder 23 is located inside the circular groove 22. An annular groove 24 is formed inside the groove cylinder 23. A number of round rods 25 are fixedly connected to the inner wall of the annular groove 24. One end of the round rod 25 is fixedly connected to a sector plate 26. A spring 27 is arranged on the outer surface of the round rod 25. Two ends of the spring 27 are respectively fixedly connected to one side of the round rod 25 and one side of the inner wall of the annular groove 24. By arranging the groove cylinder 23, when installing the thermal insulation board, a connecting workpiece such as a stud can pass through the through hole 21 on the outer surface of the plate body 1 to be connected with the wall surface. When the stud passes through the inside of the groove cylinder 23 and contacts one side of the sector plate 26, it will push the round rod 25 to slide into the annular groove 24 and compress the spring 27. The elastic force of the spring 27 pushes the sector plate 26 to limit the position of the stud inside the groove cylinder 23, as much as possible to avoid damaging the inside of the plate body 1 when connecting the plate body 1 with the wall surface through the stud, and further limit the position between the stud and the plate body 1, improving the stability of the plate body 1 after installation.

[0030] Refer to Figures 2-4 shown, in this implementation scheme: the inner diameter of the spring 27 is slightly larger than the diameter of the round rod 25. The round rod 25 is located inside the spring 27. When the spring 27 is compressed, it will move outside the round rod 25. The round rod 25 can reinforce the internal shape of the spring 27, as much as possible to avoid the spring 27 being distorted. Ribs 28 are fixedly connected to the top and bottom edges of the sector plate 26. The ribs 28 are rubber strips made of rubber. By arranging the rubber ribs 28, the friction between the stud and the top and bottom of the sector plate 26 can be increased, making it difficult for the stud to slide inside the groove cylinder 23.

[0031] Refer to Figures 2-4As shown in the figure, in this embodiment: several positioning rods 29 are fixedly connected to the inner wall of the annular groove 24. The two positioning rods 29 are respectively located on the upper and lower sides of the spring 27. By providing the positioning rods 29, the movement of the round rod 25 and the spring 27 can be restricted, and the angle of the round rod 25 can be prevented from skewing as much as possible, and the external shape of the spring 27 can be further strengthened. One end of the round rod 25 is fixedly connected with a convex block 210. The convex block 210 is a rubber block made of rubber. When the round rod 25 moves into the annular groove 24 and one end of the rubber convex block 210 abuts against the inner wall of the annular groove 24, the contact between the round rod 25 and the inner wall of the annular groove 24 can be buffered by the rubber convex block 210, and the round rod 25 and the spring 27 can be prevented from being unable to be used normally due to excessive force when the sector plate 26 is squeezed.

[0032] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in the figure, in this embodiment: a protective device 3 is provided on the outer surface of the plate body 1. The protective device 3 includes two elastic plates 32. A net plate 33 is fixedly connected to the side of the two elastic plates 32 close to each other. Card slots 31 are provided on both sides of the plate body 1. When installing the heat preservation plate, the two elastic plates 32 can be bent outward by a certain angle, and then the tops of the two elastic plates 32 can be stuck in the card slots 31 on the outer surface of the plate body 1, and the elastic plates 32 and the net plate 33 are installed on one side of the plate body 1. The surface structure outside the plate body 1 can be further strengthened by the net plate 33, and the surface part of the plate body 1 can be prevented from falling off after long-term use as much as possible.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in the figure, in this embodiment: two reinforcing rods 34 are fixedly connected to the bottom end of the net plate 33. The two ends of the two reinforcing rods 34 are respectively fixedly connected to the two diagonal corners of the net plate 33. By providing the reinforcing rods 34, the outer surface shape and structure of the net plate 33 and the plate body 1 can be further strengthened, and the durability of the plate body 1 and the net plate 33 can be improved. A convex piece 35 is fixedly connected to one side of the elastic plate 32. The convex piece 35 is a rubber piece made of rubber. After the protective device 3 is installed on the outer surface of the plate body 1, it is more convenient to pull the elastic plate 32 to deform by pinching the outer surface of the rubber convex piece 35, and the elastic plate 32 and the net plate 33 can be removed for replacement.

[0034] Working principle: When installing the heat preservation board, the two elastic plates 32 at the top of a mesh board 33 can be bent outwards at a certain angle first, and then the tops of the two elastic plates 32 are clamped at the clamping grooves 31 on the outer surface of the board body 1, so that one side of the mesh board 33 is attached to one side of the board body 1. The elastic plates 32 and the mesh board 33 are installed on one side of the board body 1, and the surface structure on the outer side of the board body 1 is further strengthened through the mesh board 33. Subsequently, mortar is applied to the side of the board body 1 away from the mesh board 33, and the side of the board body 1 coated with mortar is attached to the wall surface to connect the board body 1 with the wall surface. Then, connecting workpieces such as stud bolts are passed through the through holes 21 on the outer surface of the board body 1 and driven into the wall surface to connect with the wall surface, and the board body 1 is installed on the wall surface. When the stud bolt passes through the inside of the groove cylinder 23 and contacts one side of the sector plate 26, it will push the round rod 25 to slide into the inside of the annular groove 24 and compress the spring 27. The elastic force of the spring 27 is used to push the sector plate 26 to limit the position of the stud bolt inside the groove cylinder 23.
