DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] An embodiment of an exterior wall insulation structure for old house reconstruction according to the present invention is as follows: Figures 1 to 8 As shown, it includes a heat preservation board 200, a connection structure 300 and a glue injection structure 400.

[0030] There are a plurality of heat-insulating panels 200 , and the heat-insulating panels 200 are bonded to the exterior wall 100 after applying an adhesive on the exterior wall 100 .

[0031] The connection structure 300 includes a fixing plate 310, an inner sleeve 320 and an outer sleeve 330. The fixing plate 310 is embedded and fixed in the insulation board 200. The inner sleeve 320 is located on the side of the insulation board 200 close to the external wall 100, and one end of the inner sleeve 320 passes through the insulation board 200 and is fixed to the fixing plate 310. Specifically, a hollow groove for installing the fixing plate 310 is reserved in the insulation board 200. The fixing board 310 is fixed in the hollow groove. The inner sleeve 320 passes through the insulation board 200 from the side of the fixing plate 310 close to the external wall 100, thereby ensuring the integrity of the insulation board 200 away from the external wall 100, and preventing the inner sleeve 320 from affecting the insulation performance of the insulation board 200 away from the external wall 100. One end of the inner sleeve 320 fixed to the fixing plate 310 is a cylindrical structure closed in the circumferential direction, and the other end is a cylindrical structure surrounded by a plurality of first arc plates 321. An installation hole 110 is opened on the outer wall 100, and the outer sleeve 330 is used to cooperate with the installation hole 110; and one end of the outer sleeve 330 close to the insulation board 200 is a cylindrical structure closed in the circumferential direction, and the other end is a cylindrical structure surrounded by multiple second arc plates 331 at intervals; when the insulation board 200 is in contact with the outer wall 100, the inner sleeve 320 cooperates with the outer sleeve 330, and the first arc plate 321 of the inner sleeve 320 pushes the second arc plate 331 of the outer sleeve 330 away from each other to open or have a tendency to open.

[0032] The glue injection structure 400 includes a steel wire 410 and a glue cylinder 420 installed on the side wall of the insulation board 200. One end of the steel wire 410 is connected to the inner sleeve 320, and the other end extends out from the side wall of the insulation board 200 after passing between the insulation board 200 and the outer wall 100. The steel wire 410 is provided with saw teeth. When the steel wire 410 is tightened, the saw teeth break the glue cylinder 420, so that the glue in the glue cylinder 420 flows to the gap between the two insulation boards 200.

[0033] In the initial state, the plurality of first arc plates 321 of the inner sleeve 320 are gathered in the closed cylindrical structure of the outer sleeve 330 . When installing the insulation board 200, it is necessary to first apply adhesive on the exterior wall 100. When the insulation board 200 is close to the exterior wall 100, the cylindrical structure surrounded by the second arc plates 331 of the outer sleeve 330 is inserted into the installation hole 110 on the exterior wall 100. Then, the insulation board 200 continues to approach the exterior wall 100 until it is attached to the exterior wall 100, so that the inner sleeve 320 moves relative to the outer sleeve 330, and the first arc plate 321 of the inner sleeve 320 moves into the cylindrical structure defined by the multiple second arc plates 331 of the outer sleeve 330, and pushes the multiple second arc plates 331 away from each other to open or have a tendency to open, so that the second arc plates 331 further press against the inner wall of the installation hole 110, thereby increasing the connection strength between the outer sleeve 330 and the exterior wall 100, thereby increasing the connection strength between the insulation board 200 and the exterior wall 100. Two adjacent insulation boards 200 are attached to the exterior wall 100, and the steel wire 410 between the two insulation boards 200 is pulled, so that the steel wire 410 breaks the rubber tube 420 between the two insulation boards 200, and the glue in the rubber tube 420 flows between the two insulation boards 200 to fix the two insulation boards 200. After the adhesive coated on the exterior wall 100 solidifies, the insulation board 200 and the exterior wall 100 are reliably connected, and the steel wire 410 between the insulation board 200 and the exterior wall 100 is fixed to the adhesive, further increasing the bonding strength of the adhesive between the insulation board 200 and the exterior wall 100.

[0034] By providing an embedded fixed plate 310, and allowing the inner sleeve 320 to pass through the insulation board 200 from the side of the fixed plate 310 close to the outer wall 100, and using the inner sleeve 320 to open the outer sleeve 330 to increase the connection strength between the outer sleeve 330 and the outer wall 100, thereby increasing the connection strength between the insulation board 200 and the outer wall 100, the installation is convenient, and there is no need to punch holes in the insulation board 200; the integrity of the side of the insulation board 200 away from the outer wall 100 is ensured, the cold bridge phenomenon is avoided, and the insulation performance of the insulation board 200 is ensured. Furthermore, in the prior art, glue is usually applied in advance to the side wall of the insulation board 200, resulting in the glue applied in advance affecting the installation of the two insulation boards 200, thereby causing the connection between the two insulation boards 200 to be loose. In the present application, after the installation of two adjacent insulation boards 200 is completed, the rubber tube 420 between the two adjacent insulation boards 200 is broken by pulling the steel wire 410, so that the glue flows out to the gap between the two insulation boards 200, so that the joints between the two insulation boards 200 can be fully filled, thereby improving the overall insulation performance of the multiple insulation boards 200.

[0035] In this embodiment, the first arc plate 321 includes a connecting portion and a top block, the top block is located at the end of the connecting portion away from the fixed plate 310, and the diameter of the circumscribed circle surrounded by the top blocks of the multiple first arc plates 321 is larger than the diameter of the circumscribed circle surrounded by the connecting portions of the multiple first arc plates 321; the top block is used to abut against the second arc plate 331; and a conical surface is provided at the end of the top block away from the fixed plate 310, which is used to abut against the end surface of the outer sleeve 330, thereby guiding the multiple first arc plates 321 to gather together so that the first arc plates 321 enter the outer sleeve 330.

[0036] In this embodiment, an avoidance hole 332 is opened on the outer sleeve 330 , and one end of the steel wire 410 passes through the avoidance hole 332 and the gap between two adjacent first arc plates 321 and is connected to the fixing plate 310 .

[0037] In this embodiment, ratchets are provided on the side walls of the avoidance hole 332 . The ratchets are inclined and allow the steel wire 410 to extend away from the center of the outer sleeve 330 and prevent the steel wire 410 from moving toward the center of the outer sleeve 330 .

[0038] In this embodiment, an escape groove 210 is provided on the outer wall of the insulation board 200, and the steel wire 410 extends from the side wall of the insulation board 200 through the escape groove 210. Preferably, the escape grooves 210 on the outer walls of two adjacent insulation boards 200 are staggered, so that the steel wires 410 corresponding to the two adjacent insulation boards 200 extend from different positions between the two insulation boards 200, thereby breaking the glue cylinder 420 at different positions between the two insulation boards 200, thereby increasing the flow area of ​​the glue.

[0039] In this embodiment, a mounting groove 220 for mounting a rubber cylinder 420 is reserved on each outer side wall of the insulation board 200 . The rubber cylinder 420 is fixed in the mounting groove 220 , and a side of the rubber cylinder 420 close to the side wall of the insulation board 200 is flush with the side wall of the insulation board 200 .

[0040] In this embodiment, the cross section of the rubber cylinder 420 perpendicular to the outer wall of the insulation board 200 is semicircular, and the plane of the semicircle is flush with the side wall of the insulation board 200. There is no diaphragm between the side of the rubber cylinder 420 that is in contact with the installation groove 220 and the installation groove 220, and the glue in the rubber cylinder 420 is directly connected to the insulation board 200; the side of the rubber cylinder 420 that is flush with the outer wall of the insulation board 200 has a diaphragm to prevent the glue in the rubber cylinder 420 from flowing out, and the saw teeth on the steel wire 410 can cut the diaphragm, so that the glue flows out from the cut diaphragm.

[0041] In this embodiment, the inner sleeve 320 and the outer sleeve 330 correspond one to one and constitute a group of fasteners. There are multiple fasteners on each insulation board 200, which are distributed at intervals in the horizontal direction.

[0042] In this embodiment, there are multiple steel wires 410 corresponding to each group of fasteners. The multiple steel wires 410 are dispersedly distributed with their corresponding fasteners as the center, and at least one steel wire 410 extends from each side wall of the insulation board 200.

[0043] In this embodiment, the insulation boards 200 are staggeredly distributed on the exterior wall 100 , and in the vertical direction, the vertical side walls of the upper insulation boards 200 correspond to the middle of the lower insulation boards 200 .

[0044] When installing the insulation board 200 on the exterior wall 100 of an exterior wall insulation structure for renovating an old house according to the present invention, it is necessary to first apply an adhesive on the exterior wall 100, then move the insulation board 200 close to the exterior wall 100, insert the cylindrical structure surrounded by the second arc plates 331 of the outer sleeve 330 into the installation hole 110 on the exterior wall 100, and then move the insulation board 200 further close to the exterior wall 100 until it is attached to the exterior wall 100. During this process, the inner sleeve 320 moves relative to the outer sleeve 330, and the first arc plate 321 of the inner sleeve 320 moves into the cylindrical structure defined by the multiple second arc plates 331 of the outer sleeve 330, and pushes the multiple second arc plates 331 away from each other to open or have a tendency to open, so that the second arc plates 331 further press against the inner wall of the installation hole 110, thereby increasing the connection strength between the outer sleeve 330 and the exterior wall 100, and further increasing the connection strength between the insulation board 200 and the exterior wall 100. After the insulation boards 200 are attached to the exterior wall 100 in sequence, the steel wire 410 between the two insulation boards 200 is pulled, so that the steel wire 410 breaks the rubber tube 420 between the two insulation boards 200, and the glue in the rubber tube 420 flows between the two insulation boards 200 to fix the two insulation boards 200. After that, the excess steel wire 410 extending outside the insulation boards 200 can be cut off. After the adhesive applied on the exterior wall 100 solidifies, the insulation board 200 and the exterior wall 100 are reliably connected, and the steel wire 410 between the insulation board 200 and the exterior wall 100 is fixed to the adhesive, which further increases the bonding strength of the adhesive between the insulation board 200 and the exterior wall 100.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
