[0047] The present invention provides a dry hanging connector suitable for passive ultra-low energy consumption buildings, such as Figure 1 and Figure 2 As shown, it includes a wall end connection section 1, a heat insulation splint 2 and a dry hanging end connection section 3 which are connected in sequence;

[0048] The wall end connecting section 1 comprises a first end plate 11, a first connecting plate 14 and a first connecting tube 15 which are fixedly connected in sequence. Figure 3 As shown;

[0049] The dry hanging end connecting section 3 comprises a second end plate 31, a second connecting plate 33 and a second connecting tube 34 which are fixedly connected in sequence. Figure 4 As shown;

[0050] A heat-insulating clamp 2 is provided between the first connecting tube 15 and the second connecting tube 34. Specifically, the heat-insulating clamp 2 can prevent the wall-end connecting section 1 from directly contacting the dry-hanging end connecting section 3, thereby blocking heat transfer, and can also fit the heat-insulating body 5 in the first connecting tube 15 and the second connecting tube 34, thereby ensuring that the two heat-insulating bodies 5 will not be relatively displaced in the height direction of the heat-insulating bodies 5;

[0051] The first connecting tube 15 and the second connecting tube 34 are both variable diameter structures;

[0052] The first connecting tube 15 and the second connecting tube 34 are respectively provided with a heat insulator 5;

[0053] Specifically, the adjacent side walls of the first connecting tube 15 and the second connecting tube 34 and the adjacent side walls of the first connecting tube 15 and the first connecting plate 14 are all arranged vertically, and the remaining two side walls are arranged obliquely to form a variable diameter structure; similarly, the adjacent side walls of the second connecting tube 34 and the first connecting tube 15 and the adjacent side walls of the second connecting tube 34 and the second end plate 31 are all arranged vertically, and the remaining two side walls are arranged obliquely to form a variable diameter structure;

[0054] Furthermore, the angle between the inclined side wall of the first connecting tube 15 and the height of the first connecting tube 15 is smaller than the friction angle, which is used to ensure that the heat insulator 5 and the first connecting tube 15 will not fall out during use of the dry-hanging connector, and at the same time, the tendency of the first connecting tube 15 to prevent the heat insulator 5 in the first connecting tube 15 from shifting downward is maximized. The angle between the inclined side wall of the second connecting tube 34 and the height of the second connecting tube 34 is also smaller than the friction angle, which is used to ensure that the second connecting tube 34 and the heat insulator 5 in the second connecting tube 34 will not fall out during use of the dry-hanging connector, and at the same time, the tendency of the heat insulator 5 in the second connecting tube 34 to prevent the second connecting tube 34 from shifting downward is maximized.

[0055] Furthermore, the heat insulator 5 and the heat insulating splint 2 are both made of wood with heat insulating ability. Since wood has good processability, the heat insulator 5 can be made in various forms by cutting and merging.

[0056] The heat insulating body 5 of the first connecting tube 15 and the second connecting tube 34 is provided with an anti-bending connecting section 4 inside. Specifically, the heat insulating body 5 is provided with an anti-bending connecting groove 52 with a through height to facilitate the later connection of the anti-bending connecting section 4.

[0057] A preferred embodiment provided by the present invention is as follows: Figure 7 As shown, the anti-bending connection section 4 is made of thin-walled I-beam, which has the advantages of strong anti-bending ability and easy connection, processing and installation.

[0058] A preferred embodiment provided by the present invention is as follows: Figure 5 and Figure 6 As shown, there are two heat-insulating clamping plates 2, which are respectively stopped at the two side walls of the middle part of the anti-bending connection section 4;

[0059] The abutment end of the heat insulating splint 2 is integrally provided with a plurality of mortise and tenon blocks 21 for connecting to the heat insulating body 5 .

[0060] Further, such as Figure 8 and Fig. 9 As shown, the heat insulation body 5 is provided with mortise and tenon grooves 51 corresponding to a plurality of mortise and tenon blocks 21 .

[0061] The mortise and tenon block 21 is mortise and tenon connected to the mortise and tenon groove 51 , so that the heat insulating splint 2 can be arranged between the first connecting tube 15 and the second connecting tube 31 , and the shear resistance of the dry hanging connector can be improved.

[0062] Furthermore, the mortise and tenon block 21 is provided with a shear-resistant steel bar 22, which can fill the mortise and tenon block 21 to prevent the first connecting tube 15 and the insulation body 5 in the second connecting tube 34 from relative displacement in the height direction of the insulation body 5, thereby further improving the shear resistance of the structure.

[0063] Another preferred embodiment provided by the present invention is that the inner diameter of the lower port of the first connecting tube 15 is smaller than the inner diameter of the upper port;

[0064] The inner diameter of the lower port of the second connecting tube 34 is larger than the inner diameter of the upper port. Specifically, the projection area of ​​the thermal insulation body 5, the first connecting tube 15 and the second connecting tube 34 on the horizontal plane is relatively large. Therefore, the dry hanging connecting piece of the present application can also serve as a supporting area for supporting the building insulation layer in the area above the thermal insulation body 5, the first connecting tube 15 and the second connecting tube 34.

[0065] Another preferred embodiment provided by the present invention is that a stiffening rib 13 is provided between the first end plate 11 and the first connecting plate 14, and the stiffening rib 13 can ensure the local stability between the first end plate 11 and the first connecting plate 14, thereby improving the stability of the dry hanging connector.

[0066] Another preferred embodiment provided by the present invention is that a plurality of first connection holes 12 are provided on the first end plate 11 to facilitate connection of the first end plate 11 with a building wall or a structural component.

[0067] The second end plate 31 is provided with a plurality of second connection holes 32 , and the second connection holes 32 are used for building exterior wall panels, stone materials, building hanging panels, and the like.

[0068] The present invention provides a method for installing a dry hanging connector suitable for a passive ultra-low energy consumption building, comprising the following steps:

[0069] S1: Connect the wall end connecting section 1 to the building wall or structural component through the first end plate 11;

[0070] S2: Install the heat insulator 5 in the first connecting tube 15 and the second connecting tube 34 respectively;

[0071] S3: two heat-insulating splints 2 are used to embed two heat-insulating bodies 5 to achieve preliminary connection between the wall-end connecting section 1 and the dry-hanging end connecting section 3;

[0072] S4: Hammer the bending-resistant connecting section 4 into the predetermined position with a small force and multiple times to complete the installation of the dry hanging connecting piece.

[0073] The method has simple steps and can be completed by splicing the parts one by one according to the preset steps, thereby improving the efficiency of on-site installation.

[0074] The working principle of the connecting piece of the present application is as follows: when the wall end connecting section 1 is connected to the building wall or structural component through the first end plate 11, and the dry hanging end connecting section 3 is connected to the building wall panel through the second end plate 31, the dry hanging end connecting section 3 will have a downward shear deformation trend and a bending deformation trend relative to the wall end connecting section 1. At this time, the dry hanging end connecting section 3 will be embedded in the thermal insulation body 5 inside the dry hanging end connecting section 3, so that the dry hanging end connecting section 3 and the thermal insulation body 5 inside it cannot be sheared. Moreover, due to the self-locking principle, the tendency that the dry hanging end connecting section 3 and the thermal insulation body 5 inside it cannot be sheared is maximized. The dry hanging end connecting section 3 will also be embedded in the thermal insulation body 5 by the second connecting tube 34, so that the two cannot be bent. Then the force of the building wall panel will be transmitted to the thermal insulation body 5 along the dry hanging end connecting section 3. The two insulation splints 2 will fix the two insulation bodies 5 with mortise and tenon joints, and the shear-resistant steel strips 22 inside the insulation splints 2 will prevent the two insulation bodies 5 from relative shear deformation, and the two insulation bodies 5 will not be able to have relative angular displacement because they are each embedded with a flange of the bending-resistant connecting section 4. In addition, one insulation body 5 is also embedded in the first connecting tube 15, and the insulation body 5 in the first connecting tube 15 and the first connecting tube 15 cannot have shear deformation displacement tendency and bending deformation tendency, so the load of the building wallboard will be transmitted to the wall end connecting section 1. In the process of force transmission of the connecting piece of the present application, the use of wood with insulation ability to make the insulation body 5 and the insulation splint 2 will block the path of heat transfer along the connecting piece, so the connecting piece of the present application also has the ability to break thermal bridges.

[0075] The dry-hanging connector of the present application also has the following advantages: the thermal insulator 5, the first connecting tube 15 and the second connecting tube 34 are components of the force transmission principle of the present application, but the projection area of ​​the thermal insulator 5, the first connecting tube 15 and the second connecting tube 34 on the horizontal plane is relatively large, so the dry-hanging connector of the present application in the area above the thermal insulator 5, the first connecting tube 15 and the second connecting tube 34 can also serve as a supporting area for supporting the building insulation layer.

[0076] Considering the special force principle of the present application, it is necessary to ensure that the first connecting tube 15 of the wall end connecting section 1 has a large inner diameter at the upper end and a small inner diameter at the lower end, and the second connecting tube 34 has a small inner diameter at the upper end and a large inner diameter at the lower end.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
