DETAILED DESCRIPTION
[0036] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0037] Embodiment 1
[0038] like Figure 1-3As shown, this embodiment provides a prefabricated composite thermal insulation exterior wall panel, including a strip board 100, a thermal insulation board 200, a bonding mortar 300 and a plurality of anchors 400. A reinforcing wire mesh may be provided inside the strip board 100. The top and bottom surfaces of the strip board 100 are provided with grooves for inserting and fixing the side panels of the upper and lower connecting angle steels. The strip board 100 in this embodiment is an autoclaved aerated concrete board. In other optional embodiments, the strip board may also be a ceramsite concrete board or the like.
[0039] The insulation board 200 is bonded to the strip board 100 by the bonding mortar 300. The strip board 100 is provided with a plurality of stepped holes 110. The stepped holes 110 include a small hole 111 at the top and a large hole 112 at the bottom. The anchor 400 includes a disc 410 and an anchor rod 420. The disc 410 is arranged on the outside of the insulation board 200. The anchor rod 420 passes through the insulation board 200 and the small hole 111 and enters the large hole 112 respectively. The stepped hole 110 is filled with grouting material 113.
[0040] like Figure 3 As shown, the outer wall of the anchor rod 420 of this embodiment has threads. In other optional embodiments, such as Figure 4 As shown, the outer wall of the anchor rod 420 may also have barbs, which can increase the stability of the connection between the anchor rod 420 and the grouting material 113.
[0041] Since the grouting material 113 is filled in the small hole 111 and the punched hole at the same time, the high-strength grouting material 113 will not move upward after solidification, ensuring the firmness of the anchor 400 and the grouting material 113 after being fixed, and the anchoring force can be greatly improved compared with ordinary cylindrical holes. A groove 120 is provided on one side of the strip 100, and a protrusion 130 matching the groove 120 is provided on the other side, so that the connection between adjacent strips 100 is more stable.
[0042] The insulation board 200 can be a single material thermosetting composite polystyrene foam insulation board 200, a polyurethane board or other insulation board 200. In other optional embodiments, the insulation board 200 can also be a composite of two materials, such as Figure 5 As shown, the insulation board 200 is composed of a first insulation layer 210 and a second insulation layer 220, and the first insulation layer 210 and the second insulation layer 220 are bonded by an adhesive. The first insulation layer 210 is made of insulation materials such as thermosetting composite polystyrene foam insulation board 200 with Class A combustion performance, inorganic light aggregate, etc., with a thickness of 4cm-6cm, and the second insulation layer 220 is made of insulation materials such as polyurethane board and polystyrene board with Class B combustion performance.
[0043] Embodiment 2
[0044] The entire macropore 112 in the first embodiment is filled with grouting material 113. In this embodiment, the macropore 112 is filled with two materials. Specifically, Figure 6-7 As shown, in order to improve the thermal insulation performance of the prefabricated composite thermal insulation exterior wall panel, the large hole 112 of the stepped hole 110 is filled twice. The first time, the upper part of the large hole 112 and the small hole 111 are filled with high-strength grouting material 113. After the grouting material 113 is initially solidified, the lower part of the large hole 112 is filled with thermal insulation mortar 114. The better thermal insulation performance of the thermal insulation mortar 114 is utilized to slow down the heat transfer efficiency between the inside and outside of the exterior wall panel and improve the thermal insulation performance.
[0045] Further, if Figure 6-7 As shown, in order to improve the overall waterproof performance of the wall after multiple prefabricated composite thermal insulation exterior wall panels are assembled, U-shaped tubes 500 are respectively provided on the left and right sides between the insulation board 200 and the strip board 100, and an elastic sealing strip 510 is provided in the U-shaped tube 500 on one side, and the elastic sealing strip 510 protrudes from the U-shaped tube 500. When two adjacent prefabricated composite thermal insulation exterior wall panels are assembled, the part of the elastic sealing strip 510 protruding from the U-shaped tube 500 can be inserted into the U-shaped tube 500 of the adjacent prefabricated composite thermal insulation exterior wall panels without the elastic sealing strip 510. The shape of the elastic sealing strip 510 can be trapezoidal. When the two exterior wall panels are assembled, the elastic sealing strip 510 is squeezed and fills the U-shaped tube 500, so that moisture flowing in from the outside will not easily penetrate into the room.
[0046] The other structures and effects of this embodiment are consistent with those of the first embodiment.
[0047] Embodiment 3
[0048] The disc 410 in the first embodiment directly abuts against the heat preservation plate 200. In this embodiment, a wire mesh 600 is arranged between the disc 410 and the heat preservation plate 200. Specifically, Figure 8 As shown, the prefabricated composite thermal insulation exterior wall panel also includes a wire mesh 600 disposed between the disc 410 and the thermal insulation board 200, the disc 410 abuts against the wire mesh 600, and a mortar protective layer 700 is disposed on the outer side of the wire mesh 600, wherein the mortar protective layer 700 can be laid on the wire mesh 600 in a factory, or can be applied to the wire mesh 600 of the plurality of exterior wall panels as a whole after the plurality of exterior wall panels are installed during on-site construction. In this way, the strength of the prefabricated composite thermal insulation exterior wall panel can be improved.
[0049] The other structures and effects of this embodiment are consistent with those of the first embodiment.
[0050] Embodiment 4
[0051] The wire mesh 600 in the third embodiment directly abuts against the heat preservation board 200. A cushion strip 800 is further provided between the heat preservation board 200 and the wire mesh 600 in this embodiment. Figure 9-10As shown, the prefabricated composite insulation exterior wall panel also includes a wire mesh 600 and a plurality of pads 800 arranged between the disc 410 and the insulation board 200. The pads 800 are arranged between the insulation board 200 and the wire mesh 600 so that the wire mesh 600 is spaced apart from the insulation board 200. A mortar protective layer 700 is also provided on the upper side of the insulation board 200. Since the wire mesh 600 is spaced apart from the insulation board 200, the wire mesh 600 can be arranged in the mortar protective layer 700 during the construction of the mortar protective layer 700. At this time, the wire mesh 600 is firmly fixed by the anchor 400, and the mortar protective layer 700 is indirectly also firmly fixed to the strip board 100 by the anchor 400.
[0052] The other structures and effects of this embodiment are consistent with those of the third embodiment.
[0053] Embodiment 5
[0054] like Fig.11 , 12 As shown, both sides of the insulation board 200 extend out of the strips 100. After two adjacent prefabricated composite insulation exterior wall panels are installed, an elastic strip 230 is first arranged between the insulation boards 200 of the two adjacent prefabricated composite insulation exterior wall panels, and then a filler 140 is cast on site between the strips 100 of the adjacent prefabricated composite insulation exterior wall panels, that is, an inner template is arranged in the space for casting the filler 140 and then the filler 140 is cast. After casting, there is no gap in the exterior wall, and the waterproof performance is greatly improved. The filler 140 can be foam concrete, polystyrene particle concrete, ceramsite concrete, etc. One side of the two sides of the strip 100 of this embodiment is a protrusion 130, and the other side is a groove 120. In other optional embodiments, such as Fig.13 As shown, both sides of the strip 100 may also be provided with grooves 120 .
[0055] In this way, after multiple prefabricated composite insulation exterior wall panels are installed, pouring filler 140 can form a composite insulation exterior wall, which has good fire resistance and insulation performance and can reduce the risk of water leakage after the installation of multiple prefabricated composite insulation exterior wall panels.
