Description

Technical Field

[0001] The utility model relates to the technical field of building exterior wall thermal insulation, in particular to a non-removable composite thermal insulation board. Background Art

[0002] At present, exterior wall thermal insulation boards are bonded to the exterior walls of high-rise buildings, especially prefabricated building exterior walls. The exterior wall thermal insulation board, also called the horizon building exterior wall decoration integrated board, is composed of materials such as mortar, fiberglass mesh, and thermal insulation board. It is prefabricated in the factory and directly bonded and constructed on-site. It is the first choice for building energy-saving renovation, combining thermal insulation, corrosion resistance, and pollution-free. When prefabricating the thermal insulation board in the factory, large-sized thermal insulation boards are continuously produced on the production line, and then the thermal insulation boards are cut according to the customized requirements of building specifications. Laminations are likely to occur at both ends of the cut thermal insulation board. Moreover, when the thermal insulation board is installed on the wall later, it is necessary to drill holes in the thermal insulation board to insert anchor bolts, which further exacerbates the internal lamination of the thermal insulation board during the drilling process. After the thermal insulation board is installed on the wall, it is prone to falling off and bulging, and the structural strength of the thermal insulation board is reduced. When painting the exterior wall of the building, the real stone paint on the exterior wall surface is prone to bulging and unevenness, affecting the aesthetic degree of the building facade.

[0020] The following further elaborates on the technical solutions of the present utility model in combination with the attached Figure 1-2 ,...

[0021] As Figure 1 - Figure 2As shown in the figure, a non-dismantling composite insulation board includes an insulation layer 6, and fireproof layers 4 are respectively arranged on both sides of the insulation layer 6. That is to say, in this embodiment, fireproof layers are respectively arranged on both sides of the insulation layer. Although the previous insulation boards also had a certain fireproof effect, in order to make the overall structure of the insulation board more stable and not easy to fall off, two fireproof layers are added to the outer layer of the insulation layer, so that while the fireproof performance of the overall insulation board is increased, the structural stability of the sandwich layer inside the composite insulation board is ensured.

[0022] Specifically, as Figure 1 and Figure 2 shown, the insulation layer 6 is an insulation board, and the fireproof layer 4 is a fireproof board; a limiting block protruding outward and having a trapezoidal cross-section is arranged on the fireproof board, and a limiting groove for accommodating the limiting block is formed on the insulation board. That is to say, in this embodiment, the insulation board adopts a B1-level rubber and plastic insulation board, and the fireproof board adopts an A-level fireproof clean board. A trapezoidal limiting block is arranged on the fireproof board, and a limiting groove is arranged on the insulation board. The fireproof board is pushed onto the insulation board, and the limiting block is inserted into the limiting groove, so that a mortise and tenon connection form is formed between the fireproof board and the insulation board, and the connection strength between the insulation board and the fireproof board is greatly enhanced.

[0023] In some embodiments, the limiting blocks on two groups of the fireproof boards are arranged at intervals in a staggered manner. That is to say, the limiting grooves on both sides of the insulation board are arranged in a staggered manner, and then the limiting blocks on the fireproof boards on both sides of the insulation board are respectively inserted into the limiting grooves in a staggered manner, and the connection stability between the insulation board and the fireproof board is greatly improved by using two rows of limiting blocks.

[0024] Specifically, as Figure 1 and Figure 2 shown, a foam layer 3 is bonded to one side of the fireproof layer 4, a glass fiber layer 2 is bonded to the foam layer 3, and a first mortar layer 1 is coated on the glass fiber layer 2. That is to say, an adhesive is coated on the outer layer of one of the fireproof boards, and the foam board is bonded to the fireproof board. Since the surface of the A-level fireproof clean board has very good flatness and cleanliness, while the surface of the insulation board is relatively rough. If the adhesive is directly coated on the insulation board, the coating is uneven and it is easy to have the situation of hollowing, resulting in the foam board bonded being easy to loosen and slide off. However, the adhesive can be evenly spread on the clean surface of the fireproof board, and the effect of bonding the foam board is better, and the foam board is not easy to fall off. Then the glass fiber mesh is bonded to the foam board, and finally the mortar layer is coated on the glass fiber mesh.

[0025] It should be noted that the bonding layer 8 is the coated adhesive, and the glass fiber layer 2 is the laid glass fiber mesh.

[0026] Specifically, as Figure 1 and Figure 2As shown, the fireproof layer 4 on the other side is coated with a second mortar layer 7, and the second mortar layer 7 is coated with an adhesive layer 8. That is, the second mortar layer is coated on another layer of fireproof board, and then the adhesive is coated on the second mortar layer. When the composite insulation board is mounted on the wall, the adhesive layer adheres to the outer wall, and is reinforced with anchor bolts at the same time, so that the composite insulation board is reinforced on the outer wall as a whole.

[0027] It should be noted that a glass fiber mesh can also be laid on the outer layer of the fireproof board to enhance the uniform coating of the second mortar layer and the structural strength after solidification.

[0028] Specifically, Figure 2 As shown, the insulation layer 6, the fireproof layer 4, the foam layer 3, the glass fiber layer 2, the first mortar layer 1, the second mortar layer 7 and the bonding layer 8 form a composite insulation board as a whole; a through hole penetrating the composite insulation board and used for inserting anchor bolts is arranged along the axis perpendicular to the composite insulation board. In other words, the composite insulation board composed of a multi-layer structure is provided with a through hole for inserting anchor bolts later. When the composite insulation board is installed on the wall, the anchor bolts are directly driven into the through hole and inserted into the outer wall.

[0029] It should be noted that in the present embodiment, a PVC tube is pre-pierced through the through hole during the processing of the composite thermal insulation board, and after the processing of the composite thermal insulation board is completed, the PVC tube can be pulled out.

[0030] In some embodiments, a connection hole for the anchor bolt to pass through is opened on the stop block on one of the fireproof boards. That is, in order to facilitate the anchor bolt to pass through the composite insulation board, a connection hole with the same diameter as the anchor bolt is opened on the stop block on one of the fireproof boards.

[0031] Specifically, edge banding is respectively provided at both ends of the composite insulation board, and the edge banding includes a third mortar layer 5, and the third mortar layer 5 is coated on both ends of the composite insulation board, and an adhesive layer 8 is coated on the third mortar layer 5. That is to say, in order to prevent the internal delamination of the composite insulation board and to ensure a stable connection with adjacent composite insulation boards when installed on the wall, the third mortar layer is applied and reinforced at both ends of the composite insulation board, and finally an adhesive is coated on the third mortar layer, so that adjacent composite insulation boards are firmly bonded.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
