Description

Technical Field

[0001] The present application belongs to the field of building exterior wall insulation boards, and in particular, relates to a prefabricated building exterior wall insulation board that is not easy to fall off. Background Art

[0002] Insulation board is a very important construction content in construction projects. Its construction purpose is not only to provide people with a more comfortable living environment, but also to play a certain role in protecting the quality of the building's exterior walls. The prefabricated insulation board in the factory is easy to assemble at the construction site. Because of its good performance, it is widely used in the construction industry.

[0003] However, in recent years, partial falling of the insulation layer of the building's exterior walls has often been seen, which has greatly affected the living quality of residents and damaged their interests. It has also brought unpredictable safety hazards to residents. The falling phenomenon generally occurs at the junction of different structural layers, such as: between the bonding layer and the base layer, between the insulation layer and the bonding layer, between the plastering layer and the insulation layer, between the anchoring system and the base layer. In the case of exterior wall insulation falling off, in order to ensure the firmness of the connection between the structural layers, anchor bolts are usually used for auxiliary fixation. Construction workers need to ensure that the anchor bolts can penetrate the insulation layer mortar layer and enter the base wall. However, insufficient strength and quantity of the anchor bolts, insufficient anchoring depth, and incorrect anchoring methods will all bring risks of falling off. It can be seen that the existing technology needs to be further improved and enhanced. Utility Model Content

[0004] The utility model provides a prefabricated thermal insulation board for building exterior walls that is not easy to fall off, so as to solve the problem that the existing thermal insulation board for building exterior walls is fixed with auxiliary anchor bolts, but has no anti-falling effect due to insufficient anchor bolt strength, insufficient number, insufficient depth and other problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A prefabricated insulation board for building exterior walls that is not easy to fall off, comprising an insulation board and an anti-falling unit, wherein the insulation board is provided with a first connection surface and a second connection surface on the side facing the wall, the first connection surface is connected to the wall by bonding mortar, and the second connection surface is provided with a groove structure, and the openings at both ends of the groove structure are located on opposite sides of the insulation board;

[0007] The anti-detachment unit includes a first connecting part connected to the wall and a second connecting part connected to the insulation board. The second connecting part can enter the groove structure from the opening to form a self-locking structure, thereby limiting the insulation board from detaching from the second connecting part in a direction away from the wall, thereby improving the stability of the connection between the insulation board and the wall.

[0008] The prefabricated insulation board for building exterior walls of the present application is not easy to fall off. The insulation board is connected to the wall through a first connecting surface by bonding mortar, which provides basic connection strength, and the groove structure and anti-detachment unit of the second connecting surface provide additional support and stability. By allowing the second connecting part to enter the groove structure to form a self-locking, the insulation board is locked by a physical structure to prevent it from falling off, and the movement of the insulation board in the direction away from the wall is restricted, thereby greatly improving the stability of the connection between the insulation board and the wall. Even if the bonding mortar loses its effect due to aging, moisture intrusion or other reasons, it can effectively prevent the insulation board from falling directly. Not using anchor rods that need to penetrate the insulation board reduces the difficulty of operation, and also reduces the risk of damaging the integrity of the insulation board, thereby improving the safety of the building and the living quality of residents.

[0009] In a preferred implementation, the first connecting part is a flat plate, which is connected to the wall through anchor bolts. The second connecting part includes a vertical plate perpendicular to the flat plate and a limiting column on the end face of the vertical plate. The shape of the groove structure is adapted to the anti-detachment unit. After the first connecting surface is bonded to the wall through bonding mortar, the anti-detachment unit is integrally embedded in the groove structure.

[0010] The anchor bolts only need to penetrate the flat plate of the first connection part, which greatly simplifies the construction steps, reduces the difficulty of operation, and improves the construction efficiency. The second connection part includes a vertical plate perpendicular to the flat plate and a limiting column on the end face of the vertical plate. The shape of the groove structure is compatible with the anti-detachment unit to ensure the flatness of the insulation board.

[0011] In a preferred implementation, the cross-section of the groove structure includes an arc segment, a vertical segment and a horizontal segment, and the diameter of the limiting column is smaller than the arc segment and larger than the vertical segment.

[0012] The diameter of the limit column is smaller than the arc section but larger than the vertical section, so that the limit column can easily enter the arc section, but cannot easily pass through the vertical section. The limit column and the groove structure can only be connected vertically. This connection method is not only firm, but also can effectively prevent the insulation board from falling off in the direction away from the wall, thereby achieving self-locking.

[0013] In a preferred implementation, after the limiting column enters the arc section, the insulation board can move toward the wall to fit the adhesive mortar coated on the wall or move away from the wall to avoid the adhesive mortar coated on the wall.

[0014] In a preferred implementation, the limiting column is hollow, and an inserting portion is provided at the end thereof, and the adjacent anti-dropping units are connected as one by inserting the inserting portion into the hollow portion of the limiting column.

[0015] In a preferred implementation, the limit column is provided with an open groove, which connects the hollow area of ​​the limit column and the gap between the limit column and the insulation board. The hollow area is filled with bonding mortar to fill the gap between the limit column and the insulation board, so that the anti-detachment unit and the insulation board form an integrated structure.

[0016] By connecting multiple anti-drop units into one, multiple insulation boards are actually connected into one whole. This greatly enhances the overall stability of the insulation board system, making it less likely for the insulation board to fall off the wall. Even if one anti-drop unit fails for various reasons, the entire insulation board system is connected as a whole, and the other anti-drop units can still function to ensure that the insulation board will not fall off.

[0017] In a preferred implementation, at least one groove structure is provided.

[0018] In a preferred implementation, the insulation board and the anti-fall-off unit are both made through a prefabrication process.

[0019] In a preferred implementation, the edges on both sides of the insulation board where no opening is provided are respectively provided with stepped tongue and groove to achieve joint connection. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0030] The utility model is described below in conjunction with the accompanying drawings.

[0031] The specific plans adopted are:

[0032] like Figure 1-3As shown, the utility model provides a prefabricated insulation board for building exterior walls that is not easy to fall off, including an insulation board 1 and an anti-falling unit 2. The insulation board 1 is provided with a first connection surface and a second connection surface facing the wall, the first connection surface is connected to the wall by bonding mortar, and the second connection surface is provided with a groove structure 10, and the openings 100 at both ends of the groove structure 10 are located on the opposite sides of the insulation board 1;

[0033] The anti-detachment unit 2 includes a first connection part 20 connected to the wall and a second connection part 21 connected to the insulation board 1. The second connection part 21 can enter the groove structure 10 from the opening 100 to form a self-locking structure, thereby limiting the insulation board 1 from detaching from the second connection part 21 in a direction away from the wall, thereby improving the stability of the connection between the insulation board 1 and the wall.

[0034] The prefabricated insulation board 1 for building exterior walls of the present application is not easy to fall off. The insulation board 1 is connected to the wall through a first connecting surface by bonding mortar. This is a traditional connection method that can provide basic connection strength. The groove structure 10 and the anti-detachment unit 2 of the second connecting surface provide additional support and stability. The second connecting part 21 is allowed to enter the groove structure 10 to form a self-locking structure, and the insulation board 1 is locked by a physical structure to prevent it from falling off. This design effectively limits the movement of the insulation board 1 in the direction away from the wall, thereby greatly improving the stability of the connection between the insulation board 1 and the wall. Even if the bonding mortar loses its effect due to aging, moisture intrusion or other reasons, it can effectively prevent the insulation board 1 from falling directly. Not using anchor rods that need to penetrate the insulation board 1 reduces the difficulty of operation, and also reduces the risk of damaging the integrity of the insulation board 1, thereby improving the safety of the building and the living quality of residents.

[0035] As a preferred embodiment of the present application, the first connecting part 20 is a flat plate, which is connected to the wall through anchor bolts, thereby ensuring a stable connection between the insulation board 1 and the wall. The anchor bolts only need to penetrate the flat plate of the first connecting part 20, which greatly simplifies the construction steps, reduces the difficulty of operation, and improves the construction efficiency. The second connecting part 21 includes a vertical plate 210 perpendicular to the flat plate and a limiting column 211 on the end face of the vertical plate 210. The shape of the groove structure 10 is compatible with the anti-detachment unit 2, thereby ensuring the flatness of the insulation board 1.

[0036] For details, see Figure 2The cross-section of the groove structure 10 includes an arc segment 101, a vertical segment 102 and a horizontal segment 103. The diameter of the limiting column 211 is smaller than the arc segment 101 and larger than the vertical segment 102. The diameter of the limiting column 211 is smaller than the arc segment 101 but larger than the vertical segment 102, so that the limiting column 211 can easily enter the arc segment 101, but cannot easily pass through the vertical segment 102. The limiting column 211 and the groove structure 10 can only be connected vertically. This connection method is not only firm, but also can effectively prevent the insulation board 1 from falling off in the direction away from the wall, thereby realizing self-locking. Since the cooperation between the limiting column 211 and the arc segment 101 is based on the difference in diameter, in actual operation, the construction personnel can easily insert the limiting column 211 into the arc segment 101 of the groove structure 10, thereby reducing the construction difficulty and improving the construction efficiency.

[0037] In order to optimize the installation process of the insulation board 1, further, in the present embodiment, after the limit column 211 enters the arc segment 101, the insulation board 1 can move toward the wall 3 to fit the bonding mortar coated on the wall or move away from the wall to avoid the bonding mortar coated on the wall. Specifically, before installing the insulation board 1, the anti-slip unit 2 is first installed, and the groove structure 10 is provided with at least one groove structure. Referring to the figure, the groove structure 10 is provided at the center of the insulation board 1, and the bonding mortar is applied on both sides of the anti-slip unit 2. In this step, it is necessary to ensure that the bonding mortar is applied. Uniform and sufficient to provide sufficient bonding force, align the limiting column 211 on the insulation board 1 with the arc segment 101 in the groove structure 10, and allow it to enter smoothly. After the limiting column 211 enters the arc segment 101, the insulation board 1 needs to be moved away from the wall to avoid the bonding mortar coated on the wall, to prevent the insulation board 1 from scraping or damaging the bonding mortar on the wall during installation, thereby ensuring the bonding effect between the insulation board 1 and the wall. When the insulation board 1 is moved to the designed position, it needs to be moved toward the wall to fit the bonding mortar coated on the wall.

[0038] Furthermore, the limit column 211 is hollow, and a plug-in portion 2112 is provided at its end. The adjacent anti-detachment units 2 are inserted into the hollow part of the limit column 211 through the plug-in portion to be connected as a whole. By connecting multiple anti-detachment units 2 as a whole, multiple insulation boards 1 are actually connected as a whole. This greatly enhances the overall stability of the insulation board 1 system, making it less likely for the insulation board 1 to detach from the wall. Even if a certain anti-detachment unit 2 loses its function due to various reasons, since the entire insulation board 1 system is connected as a whole, other anti-detachment units 2 can still function to ensure that the insulation board 1 will not fall. This greatly improves the safety of the insulation board 1 system. At the same time, since multiple anti-detachment units 2 can be connected as a whole, the installer can first install many anti-detachment units 2 on the wall to correct the straight line segment. In this way, the linearity and flatness of the insulation board 1 installation can be ensured. After installing multiple anti-detachment units 2 and correcting them, multiple insulation boards 1 can be directly installed. This installation method greatly simplifies the construction steps and improves the installation efficiency.

[0039] In addition, the limiting column 211 is provided with an open groove 2111, which connects the hollow area 2110 of the limiting column 211 and the gap between the limiting column 211 and the insulation board 1. The bonding mortar 4 is filled in the hollow area 2110 to fill the gap between the limiting column 211 and the insulation board 1, so that the anti-detachment unit 2 and the insulation board 1 form an integrated structure. Specifically, the bonding mortar is filled in the hollow area 2110. The selection of the bonding mortar should have good bonding properties and fluidity to ensure that it can fully fill the gap and firmly bond to the limiting column 211 and the insulation board 1. In this way, the gap between the limiting column 211 and the insulation board 1 is completely filled to form an integral structure. The bonding mortar not only fills the gap between the limiting column 211 and the insulation board 1, but also can be connected to the mortar on the first connection surface. In this way, the insulation board 1 is not only connected to the wall through the anti-detachment unit 2, but also forms a more solid connection with the mortar on the first connection surface through the bonding mortar. This structure not only has higher strength and stability, but also can better resist the influence of external factors, such as wind, temperature changes, etc. Even in some extreme cases, such as when a certain anti-falling unit 2 loses its function, the entire insulation board 1 system can still remain stable and not easy to fall off.

[0040] As a preferred embodiment of the present application, the insulation board 1 and the anti-detachment unit 2 are both made by a prefabrication process. Through the prefabrication process, the standardized production of the insulation board 1 and the anti-detachment unit 2 can be achieved, the product quality and consistency can be improved, and the prefabricated components can be made in advance, reducing the on-site construction time and speeding up the project progress.

[0041] As a preferred embodiment of the present application, the two side edges of the insulation board 1 where the opening 100 is not provided are respectively provided with stepped tongue and groove 11 to achieve joint connection.

[0042] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0043] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
