DETAILED DESCRIPTION
[0034] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0036] Example 1
[0037] Reference Figure 1-Figure 7 The utility model provides an energy-saving insulation structure for the exterior wall of an old house, comprising: an installation assembly, including a first bracket 2 connected to the exterior wall 1, the first bracket 2 being configured to support the bottom of the insulation board 4, and a second bracket 3 connected to the exterior wall 1, the second bracket 3 being configured to limit the top of the insulation board 4, and at least one grouting hole 5 being opened on the second bracket 3; a pair of side panels 6, arranged between the first bracket 2 and the second bracket 3, the pair of side panels 6 being connected to the exterior wall 1, the insulation board 4, the first bracket 2, the second bracket 3, the pair of side panels 6 and the exterior wall 1 cooperate to form a grouting cavity 7, the grouting cavity 7 is connected to the grouting hole 5, so that grouting is injected into the grouting cavity 7 to form a grouting layer 8.
[0038] Specifically, during construction, the layout structure of the exterior wall 1 is planned, and the positions of the first bracket 2, the second bracket 3, and the side panels 6 to be pre-installed on the exterior wall 1 are leveled. After the leveling is completed, the first bracket 2, the side panels 6, and the second bracket 3 are installed on the exterior wall 1, and then the insulation board 4 is installed between the first bracket 2 and the second bracket 3 to achieve the matching and supporting connection of the first bracket 2 and the second bracket 3 to the insulation board 4. The insulation board 4, the first bracket 2, the second bracket 3, a pair of side panels 6 and the exterior wall 1 cooperate to form a grouting mold, and the grouting cavity 7 is grouted through the grouting hole 5 on the second bracket 3.
[0039] Among them, even if the surface of the exterior wall is uneven, the slurry flows in the grouting cavity 7 and fills the gap between the insulation board 4 and the exterior wall 1. It can not only avoid large-area leveling treatment of the exterior wall 1 and ensure the filling effect, thereby ensuring the insulation effect of the insulation board 4, but also the grouting solidifies to form a grouting layer 8, which can improve the strength of the exterior wall 1 and improve the connection strength between the insulation board 4 and the exterior wall 1.
[0040] In the prior art, for an exterior wall 1 with an uneven surface, it is necessary to manually plaster and level the entire area of the exterior wall 1 before installing the insulation board 4. However, in this technical solution, only a part of the exterior wall 1 needs to be plastered and leveled, and the construction effect is high.
[0041] Alternatively, the exterior wall 1 does not need to be plastered and leveled, and it is only necessary to control the position of the first support 2, the second support 3, and the side panel 6 so that there is a small gap between them and the exterior wall 1 to ensure the installation flatness of the insulation board 4. In the subsequent grouting process, the slurry can fill the small gap between the first support 2, the second support 3, the side panel 6 and the exterior wall 1 to ensure the slurry filling effect and the insulation effect of the insulation board 4.
[0042] Further, refer to Figure 1 、 Figure 2 , further comprising a caulking layer 19, which is filled between two adjacent insulation boards 4 arranged vertically. The thickness of the first and second brackets 2, 3 is less than that of the caulking layer 19. Therefore, after the two adjacent insulation boards 4 are installed, a gap exists between the two insulation boards 4, exposing the first and second brackets 2, 3. Therefore, adhesive is filled into the gap to seal the gap while shielding the first and second brackets 2, 3, and the grouting holes 5.
[0043] In this embodiment, refer to Figure 5 、 Figure 6 、 Figure 7 , further comprising a positioning unit connected to the bottom end of the first bracket 2, the positioning unit being snap-connected to the top end of the second bracket 3 in another mounting assembly located below.
[0044] In this embodiment, refer to Figure 5 、 Figure 6 、 Figure 7The positioning unit includes a protruding plate 9 fixed to the bottom end of the first bracket 2, and a connecting groove 10 matching the protruding plate 9 is opened at the top of the second bracket 3. The protruding plate 9 is located in the connecting groove 10, so that the first bracket 2 and the second bracket 3 in the two adjacent mounting assemblies arranged above and below are located on the same vertical plane.
[0045] Specifically, the first bracket 2 and the second bracket 3 in the two installation assemblies arranged above each other are connected by a positioning unit snap-on connection, that is, after the second bracket 3 below is installed, the first bracket 2 is installed above the second bracket 3, and the protruding plate 9 on the first bracket 2 is placed into the connecting groove 10, and then the first bracket 2 is fixed to the outer wall 1, so that the first bracket 2 and the second bracket 3 can be located on the same vertical plane, thereby ensuring that the two insulation boards 4 arranged above and below are located on the same vertical plane.
[0046] The first bracket 2 and the second bracket 3 are connected by snapping, and the first bracket 2 and the second bracket 3 can limit each other to improve the installation strength of the first bracket 2 and the second bracket 3.
[0047] In this embodiment, refer to Figure 6 , and also includes a supporting plate 11, which is arranged on the end surface of the side panel 6 away from the outer wall 1. The supporting plate 11 includes a connecting section 1101 fixed on the side panel 6, and an extending section 1102 connected to the connecting section 1101. The extending section 1102 is inclined relative to the side panel 6, and a hook groove 12 adapted to the extending section 1102 is opened at one end of the insulation board 4 close to the side panel 6.
[0048] Specifically, a support plate 11 is fixed on the outer wall of the side panel 6. The support plate 11 has an inclined extension section 1102. When installing the insulation board 4, the insulation board 4 can be hung on the extension section 1102 through the hook groove 12 to limit the insulation board 4 and improve the connection strength between the insulation board 4 and the outer wall 1.
[0049] In this embodiment, refer to Figure 5 、 Figure 6 、 Figure 7 The first supporting member 2 includes: a first vertical section 201, which is arranged parallel to the outer wall 1, and a first supporting section 202 is fixed on the bottom of the end surface of the first vertical section 201 away from the outer wall 1; at least one first protruding section 203 is fixed on the top of the first supporting section 202, and a first card groove 204 adapted to the first protruding section 203 is opened at the bottom end of the insulation board 4; a plurality of first anchor bolts 13 are passed through the first vertical section 201, and the ends are fixed to the outer wall 1.
[0050] Specifically, the first vertical section 201 is in contact with or not in contact with the exterior wall 1 , the first supporting section 202 is used to support the bottom end of the insulation board 4 , and the first protruding section 203 cooperates with the first slot 204 to support the insulation board 4 .
[0051] The first anchor bolt 13 is used to fix the first vertical section 201 on the outer wall 1 . Meanwhile, the first anchor bolt 13 can be used to adjust the distance between the first vertical section 201 and the outer wall 1 .
[0052] In a specific embodiment of the present invention, two first protruding sections 203 are provided, and the two first protruding sections 203 have different heights, and the first protruding section 203 with a higher height is away from the outer wall 1. Two first card grooves 204 are provided, and the depths of the two first card grooves 204 are adapted to the two first protruding sections 203.
[0053] In this embodiment, refer to Figure 5 、 Figure 6 , and also includes first grooves 14 that match the number of first anchor bolts 13. The first grooves 14 are opened on the end surface of the first vertical section 201 away from the exterior wall 1, and the ends of the first anchor bolts 13 are located in the first grooves 14.
[0054] The first groove 14 is used to accommodate the end of the first anchor bolt 13 so that the end of the first anchor bolt 13 does not protrude beyond the first vertical section 201 away from the end surface of the exterior wall 1 to avoid the first anchor bolt 13 affecting the installation of the insulation board 4.
[0055] In this embodiment, refer to Figure 5 、 Figure 6 、 Figure 7 The second bracket 3 includes: a second vertical section 301, which is arranged parallel to the outer wall 1, and a second supporting section 302 is fixed on the top of the end surface of the second vertical section 301 away from the outer wall 1; at least one second protruding section 303 is fixed to the bottom end of the second supporting section 302, and a second card groove 304 adapted to the second protruding section 303 is opened at the top of the insulation board 4; a plurality of second anchor bolts 15 are passed through the second vertical section 301, and the ends are fixed to the outer wall 1.
[0056] Specifically, the second vertical section 301 is in contact with or not in contact with the exterior wall 1 , the second supporting section 302 is used to limit the top of the insulation board 4 , and the second protruding section 303 cooperates with the second slot 304 to limit the insulation board 4 .
[0057] The second anchor bolt 15 is used to fix the second vertical section 301 on the outer wall 1 . Meanwhile, the second anchor bolt 15 can be used to adjust the distance between the second vertical section 301 and the outer wall 1 .
[0058] In a specific embodiment of the present invention, two second protruding sections 303 are provided, and the two second protruding sections 303 have different heights, and the second protruding section 303 with a higher height is away from the outer wall 1. Two second card grooves 304 are provided, and the depths of the two second card grooves 304 are adapted to the two second protruding sections 303.
[0059] In this embodiment, refer to Figure 7, and also includes a grouting channel 16, which is opened on the end face of the second vertical section 301 away from the outer wall 1, the grouting hole 5 is connected to the grouting cavity 7 through the grouting channel 16, and the end of the second anchor bolt 15 is set in the grouting channel 16.
[0060] Specifically, the existence of the grouting channel 16 not only accommodates the second anchor bolt 15, so that the end of the second anchor bolt 15 does not affect the normal laying of the insulation board 4, but also, the grouting channel 16 serves as the flow path of the slurry, and the slurry is pumped from the grouting hole 5 into the grouting channel 16, and then the grouting cavity 7 is filled with slurry from the grouting channel 16.
[0061] Further, refer to Figure 7 A notch 20 is formed at the bottom of the grouting channel 16, which is in communication with the grouting channel 16, and the rod portion of the second anchor bolt 15 is located in the notch 20. The second anchor bolt 15 is set in the notch 20. When the second bracket 3 is installed, the tightness of the second anchor bolt 15 is adjusted so that the second vertical section 301 can move under the drive of an external force, thereby driving the second supporting section 302 and the second protruding section 303 to move up and down, ensuring that during the installation of the insulation board 4, the second vertical section 301, the second supporting section 302, and the second protruding section 303 are slightly higher. After the insulation board 4 is installed, the second vertical section 301 is driven to drive the second supporting section 302 and the second protruding section 303 downward, so that the second protruding section 303 extends into the second clamping groove 304, ensuring the clamping and clamping of the insulation board 4. At the same time, when the first vertical section 201 located above the second vertical section 301 is installed, the protruding plate 9 is used to cooperate with the connecting groove 10 to further limit the second vertical section 301 .
[0062] In this embodiment, when the number of grouting holes 5 is not less than two, one of the grouting holes 5 is configured to inject grouting into the grouting cavity 7, and the remaining grouting holes 5 are configured to evacuate the grouting cavity 7 so as to form a grouting layer 8 in the grouting cavity 7.
[0063] Specifically, in order to ensure the filling effect of the grouting cavity 7, when a certain grouting hole 5 is grouting into the grouting cavity 7, one or more other grouting holes 5 can select one or more to pump air, so that the gas in the grouting cavity 7 is reduced to improve the grouting effect of the grouting cavity 7.
[0064] In this embodiment, refer to Figure 5 、 Figure 6 , and also includes at least one third anchor bolt 17, which is passed through the side panel 6 and fixed to the outer wall 1 at its end. A second groove 18 is opened on the side wall of the side panel 6 away from the outer wall 1, and the end of the third anchor bolt 17 is located in the second groove 18.
[0065] Specifically, the side panel 6 is fixed to the exterior wall 1 via the third anchor bolt 17 . Meanwhile, the second groove 18 ensures that the end of the third anchor bolt 17 does not affect the laying of the insulation board 4 .
[0066] Specifically, during construction, the layout structure of the exterior wall 1 is planned, and the positions of the first support 2, the second support 3, and the side panels 6 pre-installed on the exterior wall 1 are leveled. After leveling is completed, the first vertical section 201, the two side panels 6, and the second vertical section 301 are installed on the exterior wall 1, and then the insulation board 4 is placed on the first supporting section 202, so that the first protruding section 203 is located in the first groove 204, and the extension section 1102 is placed in the hook groove 12. Then, the second vertical section 301 is moved downward so that the second supporting section 302 contacts the top of the insulation board 4, and the second protruding section 303 is placed in the second groove 304. Then, another first vertical section 201 is installed on the top of the second vertical section 301, and the second vertical section 301 is fixed by the first vertical section 201. After the insulation board 4 is installed, grouting is injected into the grouting cavity 7 through the grouting hole 5. After the slurry solidifies, a grouting layer 8 is formed, thereby completing the installation of the insulation board 4.
[0067] Example 2
[0068] Based on Example 1, Figure 8 The arc-shaped spring piece 21 is fixed on the end surface of the second vertical section 301 and the side panel 6 close to the outer wall 1. After the second vertical section 301 is installed, the arc-shaped spring piece 21 is squeezed and the end close to the outer wall 1 is in contact with the outer wall 1.
[0069] Under the above structure, when the outer wall 1 is not leveled, even if the surface of the outer wall 1 is uneven, the arc-shaped spring piece 21 can block most of the gap between the second vertical section 301 and the outer wall 1 to form the grouting cavity 7.
[0070] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
