[0001] This utility model relates to the technical field of building exterior wall decorative composite panels, specifically an energy-saving and environmentally friendly building exterior wall insulation and decorative composite panel. Background Technology
[0002] Building energy conservation technology has become an important aspect of building technology development worldwide. A crucial element of building energy conservation is wall insulation. Insulated decorative composite panels, a new type of insulation and decorative material developed in recent years, are exterior wall systems with excellent thermal insulation, environmental performance, and durability, aiming to reduce energy consumption, protect the environment, and extend the lifespan of buildings.
[0003] Some energy-saving and environmentally friendly building exterior wall insulation and decoration composite panels are fixed to the wall by applying adhesive. However, the adhesive tends to lose its stickiness after prolonged use, resulting in an unreliable fixation between the composite panel and the wall, which increases the probability of the composite panel falling off. Therefore, this method does not meet the current needs. To address this, we propose an energy-saving and environmentally friendly building exterior wall insulation and decoration composite panel. Utility Model Content

However, after long-term use, the adhesive is prone to reduced adhesion, which leads to unreliable fixation between the composite panel and the wall, thereby increasing the probability of the composite panel falling off.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly building exterior wall insulation and decoration composite panel, comprising a composite panel, wherein a connecting groove is formed in the middle of the outer surface of the composite panel, and a connecting block is connected between two adjacent connecting grooves of the composite panel; the composite panel comprises a substrate, an insulation layer, a heat insulation layer, a waterproof layer, and a decorative layer; the insulation layer is bonded to one side of the substrate, the heat insulation layer is bonded to the side of the insulation layer away from the substrate, the waterproof layer is bonded to the side of the heat insulation layer away from the insulation layer, and the decorative layer is bonded to the side of the waterproof layer away from the heat insulation layer.
[0006] Preferably, limit blocks are fixedly connected to both sides of the inner wall of the connecting groove. The connecting blocks are T-shaped, and limit grooves are provided on both the front and back sides of the connecting blocks near the upper end.
[0007] Preferably, the two sides of the connecting block near the upper end are respectively engaged in the two adjacent connecting slots, and the limiting block is inserted into the corresponding limiting slot.
[0008] Preferably, the top of the connecting block has a groove, and the groove is threadedly connected to a threaded rod that extends through to the outer side of the bottom end of the connecting block.
[0009] Preferably, the insulation layer is made of polystyrene foam, and the heat insulation layer is made of rock wool.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model fixes the connecting block to the building exterior wall by placing the connecting block at a suitable position on the building exterior wall, threading a threaded rod through the connecting block, and fixing one end of the threaded rod inside the building exterior wall. Then, the connecting groove on one side of the composite board is connected to the connecting block, and the limiting block inside the connecting groove is inserted into the limiting grooves on both sides of the connecting block, thereby connecting and fixing the composite boards to the building exterior wall, avoiding the unreliability caused by the composite board being connected to the exterior wall by adhesive.
[0012] 2. This utility model utilizes polystyrene foam as the insulation layer, giving the composite board excellent thermal insulation performance and a low thermal conductivity. This effectively prevents heat transfer and improves the building's insulation effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figures 1 to 3This utility model provides an embodiment of an energy-saving and environmentally friendly building exterior wall insulation and decoration composite panel, comprising a composite panel 1, a connecting groove 106 formed in the middle of the outer surface of the composite panel 1, and a connecting block 2 connecting the connecting grooves 106 of two adjacent composite panels 1. The composite panel 1 includes a base plate 101, an insulation layer 102, a heat insulation layer 103, a waterproof layer 104, and a decorative layer 105. The insulation layer 102 is bonded to one side of the base plate 101, the heat insulation layer 103 is bonded to the side of the insulation layer 102 away from the base plate 101, the waterproof layer 104 is bonded to the side of the heat insulation layer 103 away from the insulation layer 102, and the decorative layer 105 is bonded to the side of the waterproof layer 104 away from the heat insulation layer 103.
[0019] The top of the connecting block 2 has a groove 201, and the inside of the groove 201 is threaded with a threaded rod 4 that extends through to the outside of the bottom of the connecting block 2. By placing the connecting block 2 at a suitable position on the exterior wall of the building, and then threading the threaded rod 4 through the connecting block 2, so that one end of the threaded rod 4 is fixed inside the exterior wall of the building, the connecting block 2 is installed and fixed on the exterior wall of the building.
[0020] Limiting blocks 3 are fixedly connected to both sides of the inner wall of the connecting groove 106. The connecting block 2 is T-shaped, and limiting grooves 202 are opened on both the front and back sides of the connecting block 2 near the upper end. The two sides of the connecting block 2 near the upper end are respectively engaged in the interior of two adjacent connecting grooves 106, and the limiting blocks 3 are inserted into the corresponding limiting grooves 202. By connecting the connecting groove 106 on one side of the composite board 1 with the connecting block 2, and making the limiting blocks 3 inside the connecting groove 106 insert into the limiting grooves 202 on both sides of the connecting block 2, the composite boards 1 are connected and fixed to the exterior wall of the building, avoiding the unreliability caused by the composite board 1 being connected to the exterior wall by adhesive.
[0021] The insulation layer 102 is made of polystyrene foam, giving the composite board 1 excellent thermal insulation performance and a low thermal conductivity, effectively preventing heat transfer and improving the building's insulation effect. The heat insulation layer 103 is made of rock wool, giving the composite board 1 excellent heat insulation performance and fire resistance. The fiber structure of rock wool allows it to maintain a stable indoor temperature even under extreme temperature differences, and it also has natural fire-resistant properties, effectively preventing the spread of fire.
[0022] When using the energy-saving and environmentally friendly building exterior wall insulation and decoration composite panel, the connecting block 2 is placed in a suitable position on the building exterior wall, and then the threaded rod 4 is threaded through the connecting block 2, with one end of the threaded rod 4 being fixed inside the building exterior wall, thereby installing and fixing the connecting block 2 to the building exterior wall. Then, the connecting groove 106 on one side of the composite panel 1 is aligned with the connecting block 2, and the limiting block 3 inside the connecting groove 106 is inserted into the limiting grooves 202 on both sides of the connecting block 2, thereby connecting the composite panels 1 together and fixing them to the building exterior wall, avoiding the unreliability caused by the composite panel 1 being connected to the exterior wall by adhesive.
[0023] The composite panel 1, with its polystyrene foam insulation layer 102, possesses excellent thermal insulation performance and a low thermal conductivity, effectively preventing heat transfer and improving the building's insulation effect. The rock wool insulation layer 103 further enhances the composite panel 1's thermal insulation and fire resistance. The fibrous structure of rock wool allows it to maintain stable indoor temperatures even under extreme temperature differences and possesses natural fire-resistant properties, effectively preventing the spread of fire.
