Example Embodiment
[0037] Example 1: Such as Figure 1 ~ Figure 5 As shown, an existing building exterior wall thermal insulation integrated structure includes an existing wall 1, an insulation board 4 and a surface layer 7. The inner side of the insulation board 4 is arranged on the outside of the existing wall 1, and the insulation board 4 The outer side is connected with the surface layer 7, and the surface layer 7 is longitudinally arranged with a grid-like steel mesh 5; the existing wall 1, the insulation board 4 and the surface layer 7 are reserved with communicating circular holes, Both ends of the circular hole do not exceed both sides of the existing wall 1 and the surface layer 7, and the connecting pipe 3 is arranged horizontally in the circular hole; the connecting pipe 3 is a circular pipe, and the connecting pipe 3 is arranged in The end surface of the existing wall 1 is uniformly provided with slits 8, the connecting pipe 3 is provided with a first circular hole 9 on the right side ...
Example Embodiment
[0044] Example 2: Such as Figure 6~Figure 11 The construction method of the existing building external wall thermal insulation integrated structure based on the existing building external wall thermal insulation integrated structure shown includes the following processes:
[0045] a) Drill a hole, drill the fixing hole 11 of the connecting pipe 3 in the existing wall 1, and the diameter of the fixing hole 11 is transitionally matched with the connecting pipe 3, and the fixing hole 11 is reamed close to the inner side of the existing wall 1, The size of the reaming hole is matched with the tube gasket 2;
[0046] When drilling the holes, the distance between the fixing holes 11 and the inner surface of the existing wall 1 is no less than 40mm, and the bidirectional distance between the fixing holes 11 is no more than 1000mm.
[0047] b. Install the connecting pipe 3 and the pipe gasket 2. Place the pipe gasket 2 on the end of the connecting pipe 3 with slit 8 and thread the tie rod 1...
