Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulation board technology, and in particular to an energy-saving, environmentally friendly, green building exterior wall insulation board. Background Technology
[0002] When constructing green buildings, insulation boards need to be installed on the exterior walls to improve thermal insulation performance. Insulation boards are typically fixed to the exterior walls using concrete or cement. However, existing insulation boards lack sufficient adhesion and tend to detach from the walls after a period of time. Furthermore, current insulation boards are installed individually, without interconnection, resulting in insufficient overall stability and a tendency to fall off. Therefore, there is an urgent need to develop an energy-saving and environmentally friendly green building exterior wall insulation board that offers high stability with concrete, convenient interconnection, greater overall stability, and is less prone to detachment. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content
[0003] The purpose of this utility model is to provide an energy-saving, environmentally friendly, and green building exterior wall insulation board to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An energy-saving and environmentally friendly green building exterior wall insulation board includes an extruded polystyrene foam board and a metal mesh. The metal mesh is fixed to the front side of the extruded polystyrene foam board, and multiple protrusions are fixed on the metal mesh. A snap-fit block is fixed to the left side of the extruded polystyrene foam board, and a slot for snapping the snap-fit block is provided on the right side of the extruded polystyrene foam board. The width of the slot gradually decreases from right to left. The width of the right end of the slot is greater than the thickness of the snap-fit block, and the width of the left end of the slot is less than the thickness of the snap-fit block.
[0006] Preferably, the snap-fit block is made of plastic.
[0007] Preferably, a sound insulation board is fixed to the rear side of the extruded polystyrene foam board.
[0008] Preferably, the rear side of the sound insulation panel is coated with a fire-retardant coating.
[0009] Preferably, the fireproof coating is applied by spraying with water-based inorganic fireproof paint.
[0010] The beneficial effects of this utility model are as follows: During installation, the protrusions of this energy-saving and environmentally friendly green building exterior wall insulation board are inserted into the concrete, thereby increasing the connection stability between the extruded polystyrene foam board, the metal mesh, and the concrete. This reduces the risk of the extruded polystyrene foam board detaching from the building's exterior wall. Furthermore, as the snap-fit blocks on one extruded polystyrene foam board are gradually inserted into the slots of another, they are gradually tightened, connecting adjacent extruded polystyrene foam boards together. This process connects multiple extruded polystyrene foam boards together, improving overall stability and further reducing the risk of detachment. The extruded polystyrene foam board provides insulation, the sound insulation board provides sound insulation, and the fireproof coating provides fire protection, thus enhancing overall performance. In summary, this utility model offers high connection stability with concrete, convenient interconnection and fixing, higher overall stability, and is less prone to detachment; it also boasts multiple functions, including insulation, sound insulation, and fireproofing.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] See Figures 1-5 In this embodiment of the utility model, an energy-saving and environmentally friendly green building exterior wall insulation board includes an extruded polystyrene foam board 1 and a metal mesh 4. The metal mesh 4 is fixed to the front side of the extruded polystyrene foam board 1. The extruded polystyrene foam board 1 itself has good thermal insulation performance. Multiple protrusions 401 are fixed on the metal mesh 4. During installation, the protrusions 401 are inserted into the concrete, thereby increasing the connection stability between the extruded polystyrene foam board 1, the metal mesh 4, and the concrete, thus reducing the risk of the extruded polystyrene foam board 1 detaching from the building exterior wall. The left side of the extruded polystyrene foam board 1... A snap-fit block 101 is fixed in place. The snap-fit block 101 is made of plastic, giving it a certain elastic deformation capability. A slot 102 for snapping the snap-fit block 101 is provided on the right side of the extruded polystyrene foam board 1. The width of the slot 102 gradually decreases from right to left. The width of the right end of the slot 102 is greater than the thickness of the snap-fit block 101, and the width of the left end of the slot 102 is less than the thickness of the snap-fit block 101. As the snap-fit block 101 is gradually inserted into the slot 102, it will be gradually locked in place, thereby connecting two adjacent extruded polystyrene foam boards 1 together and improving the overall stability.
[0021] A sound insulation board 2 is fixed to the rear side of the extruded polystyrene foam board 1, which provides sound insulation.
[0022] The rear side of the sound insulation panel 2 is coated with a fireproof coating 3, which is made of water-based inorganic fireproof paint. The fireproof coating 3 increases the overall fire resistance.
[0023] Working principle: During installation, the protrusion 401 of this energy-saving and environmentally friendly green building exterior wall insulation board is inserted into the concrete, thereby increasing the connection stability between the extruded polystyrene foam board 1, the metal mesh 4, and the concrete, thus reducing the risk of the extruded polystyrene foam board 1 falling off the building exterior wall. In addition, as the snap-fit block 101 on one extruded polystyrene foam board 1 is gradually inserted into the snap-fit groove 102 of another extruded polystyrene foam board 1, it will be gradually locked, thereby connecting two adjacent extruded polystyrene foam boards 1 together. In this way, multiple extruded polystyrene foam boards 1 are connected together, improving the overall stability and reducing the risk of the extruded polystyrene foam board 1 falling off the building exterior wall. The extruded polystyrene foam board 1 provides thermal insulation, the sound insulation board 2 provides sound insulation, and the fireproof coating 3 provides fireproofing, thereby improving the overall performance.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
