[0018] The technical solution of the present utility model will be further described below with reference to the drawings and through specific embodiments.
[0019] AsFigure 1-2 As shown in Figure 1-2 , in the embodiment, an exterior wall insulation board with a moisture-proof function is provided, which includes an installation frame 1, a connection unit 2, a heat preservation unit 3 and a moisture-proof unit 4. A connection unit 2 is arranged on the outer side of the installation frame 1. The connection unit 2 includes an insertion block 21, a sliding block 23, a transmission rod 24, a support rod 25, a sealing baffle 26 and an elastic sealing strip 27. An insertion block 21 is arranged on one side of the installation frame 1, and a slot 22 corresponding to the insertion block 21 is arranged on the other side of the installation frame 1. A sliding block 23 is slidably connected in the slot 22. A through hole 28 connected to the slot 22 is arranged on the installation frame 1. A support rod 25 is slidably connected in the through hole 28. One end of the transmission rod 24 is hinged to the sliding block 23, and the other end of the transmission rod 24 is hinged to the end of the support rod 25. The free end of the support rod 25 is connected to the sealing baffle 26, and an elastic sealing strip 27 is also arranged on the sealing baffle 26. The heat preservation unit 3 and the moisture-proof unit 4 are sequentially arranged on the inner side of the installation frame 1 from the inside to the outside. In this embodiment, during installation, the side of the insulation board close to the wall is called the "reverse side" or "inner side", and the side away from the wall is called the "front side" or "outer side". The installation frame 1 is a rectangular frame, which is processed and manufactured by engineering plastics. While ensuring strength, it is also relatively light in weight, which helps to reduce the overall weight of the insulation board. The connection unit 2 is used to connect two adjacent insulation boards, and the installation is convenient and fast, which helps to improve the construction efficiency. Among them, the insertion block 21 and the slot 22 are in plug-in fit, which can fix the installation frames 1 of two adjacent insulation boards into one body. And when the insertion block 21 is inserted into the slot 22, it can also push the sliding block 23 to slide in the slot 22. The through hole 28 is located on the front side of the installation frame 1. The support rod 25 can slide in the through hole 28, and the arranged transmission rod 24 enables the sliding block 23 to move synchronously with the support rod 25. The arranged sealing baffle 26 is used to block the gap at the connection of two adjacent installation frames 1 to prevent rainwater from seeping in through the gap and causing corrosion and damage to the wall, the heat preservation unit, etc. The arranged elastic sealing strip 27 can assist the sealing baffle 26 to seal the gap and improve the sealing performance. The arranged heat preservation unit 3 can play a role in heat preservation and reduce the temperature difference between the inside of the moisture-proof unit 4 and the external environment, thereby reducing the phenomenon of condensation on the surface of the insulation board. The arranged moisture-proof unit 4 can reduce the situation of the wall being damaged by moisture and extend the service life. In addition, a sticking block is also arranged on the reverse side of the installation frame 1, which is convenient to stick and fix the installation frame 1 on the wall to prevent the insulation board from falling off during construction and causing safety problems.
[0020] Specifically, the heat preservation unit 3 includes a support layer 31, a heat preservation layer 32 and a fireproof layer 33 which are sequentially arranged from the inside to the outside. In this embodiment, the arranged support layer 31 can support the heat preservation layer 32, the fireproof layer 33 and the moisture-proof unit 4, thereby improving the overall compressive performance and anti-bending performance of the insulation board. The arranged heat preservation layer 32 can play a role in heat preservation and heat insulation, and the arranged fireproof layer 33 can improve the fireproof performance of the insulation board to eliminate potential safety hazards.
[0021] Specifically, reinforcing steel wires 34 are embedded inside the support layer 31, and both ends of the reinforcing steel wires 34 are connected to the mounting frame 1. In this embodiment, there are two or more reinforcing steel wires 34, and the arranged reinforcing steel wires 34 can further improve the anti-bending ability of the support layer 31. Both ends of the reinforcing steel wires 34 are fixed on the inner side wall of the mounting frame 1 by welding, thereby connecting the heat preservation unit 3 and the mounting frame 1 into an integrated body.
[0022] Specifically, the moisture-proof unit 4 includes a heat radiation reflection layer 41, a moisture-proof layer 42, and a waterproof layer 43 arranged in sequence from inside to outside. A diversion groove 44 is provided on the waterproof layer 43, a water guide pipe 45 is provided at the lowest point of the diversion groove 44, and one end of the water guide pipe 45 extends out of the diversion groove 44. In this embodiment, the heat radiation reflection layer 41 can reflect the heat radiation back to improve the heat preservation ability of the heat preservation layer 32. And on a sunny day, the reflected heat radiation can accelerate the evaporation of moisture in the moisture-proof layer 42 and the waterproof layer 43, enabling the heat preservation board to dry quickly. The provided moisture-proof layer 42 can play a moisture-proof role, and the provided waterproof layer 43 can block rainwater from seeping into the moisture-proof unit 4. The provided diversion groove 44 can gather the water droplets on the surface of the waterproof layer 43 into the groove and discharge them through the water guide pipe 45. Since the length of the water guide pipe 45 is greater than the depth of the diversion groove 44, the discharged water will not contact the heat preservation board at this time, thereby reducing the amount of rainwater flowing through the connection gap between two adjacent mounting frames 1, so as to assist in improving the anti-seepage ability.
[0023] Specifically, the diversion groove 44 is a V-shaped groove. In this embodiment, there are two or more V-shaped grooves, and two or more V-shaped grooves are arranged at equal intervals.
[0024] Specifically, a super-hydrophobic coating is further provided on the surface of the waterproof layer 43. In this embodiment, the use of the super-hydrophobic coating can reduce the adhesion of water droplets on the surface of the waterproof layer 43, enable the water droplets to quickly condense and flow into the diversion groove 44, and help keep the surface of the waterproof layer 43 always dry.
[0025] Working principle: When installing the exterior wall heat preservation board, first pick up a heat preservation board and adhere it to the wall. Then pick up another heat preservation board, insert the insertion block 21 of the second heat preservation board into the slot 22 of the first heat preservation board and press it tightly. At this time, the insertion block 21 will push the slider 23 to move, and then drive the sealing baffle 26 to move synchronously through the transmission rod 24, thereby blocking the gap at the connection of the first heat preservation board and the second heat preservation board to prevent rainwater from seeping into the interior of the heat preservation board through the gap and causing damage to the wall due to moisture. Then repeat the above steps until the installation of the entire wall is completed.
[0026] The present utility model is described by way of preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. The present utility model is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application all belong to the scope of protection of the present utility model.
