Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, specifically to a wall structure. Background Technology

[0002] In the field of modern building energy conservation and environmental protection, ultra-low energy consumption buildings and the renovation and upgrading of existing buildings have become important directions for promoting the development of green buildings. Among these, the insulation layer, as a key structural layer for improving building energy efficiency, directly affects the building's thermal insulation effect and overall energy efficiency level through its construction quality and performance. Currently, the common construction method for insulation layers is to connect them to the base wall using plastic anchors. However, traditional plastic anchors lack sufficient rigidity and are unable to effectively withstand heavy loads, especially in areas with poor construction quality or weak local load-bearing capacity, making them more prone to slippage and cracking, among other safety hazards. These problems not only affect the building's aesthetics and functionality but also pose a serious threat to the overall structural safety of the building. Utility Model Content

[0003] The purpose of this utility model is to provide a novel wall structure. By improving the wall structure, the thermal bridging effect of the anchors is ensured, while the load-bearing capacity of the anchors is improved, thereby enhancing the overall structural safety of the building.

[0004] To achieve the above objectives, this utility model provides a wall structure comprising a base wall layer, a first cladding layer, and a first fastener. The first fastener is used to connect the base wall layer and the first cladding layer, and the first fastener is made of metal. The first fastener includes a first section, a second section, and a thermally insulating connector. The first section and the second section are arranged sequentially at intervals along the thickness direction of the wall structure. At least a portion of the first section is fixed to the base wall layer, and one end of the second section extends to the surface of the first cladding layer away from the base wall layer and abuts against that surface. The first section and the second section are connected by the thermally insulating connector.

[0005] In the embodiments of this application, by using a metal first fastener as an anchor to connect the first cladding layer and the base wall layer, the connection strength between the first cladding layer and the base wall layer is improved. At the same time, a spacer is provided between the second section and the first section of the first fastener, thereby blocking the heat conduction between the first section and the second section and improving the overall structural safety of the building.

[0006] Optionally, the thermal insulation connector includes a sleeve, one end of which is fitted onto one end of the second segment, and the other end of which is fitted onto one end of the first segment. The spacer is located inside the sleeve. By using a sleeve, the first segment and the second segment are connected, and a spacer is provided in the middle of the sleeve. The spacer contains gas that is sealed inside during installation, thereby further improving the thermal conductivity resistance between the first segment and the second segment.

[0007] Optionally, the first connecting end and the second connecting end are threadedly connected to the sleeve. The threaded connection improves the ease of operation when connecting the first and second sections.

[0008] Optionally, the radial dimensions of the first connecting end and the second connecting end are the same, and the consistency of the dimensions of the first connecting end and the second connecting end simplifies the processing and installation procedures.

[0010] By adopting this method, the first coating and the second coating are connected by a first adapter, a first fastener, a second fastener, and a second adapter. The first adapter, the first fastener, the second fastener, and the first adapter are all made of metal, which improves the connection strength between the first coating and the second coating.

[0011] Optionally, the end of the second segment that is far from the sleeve is defined as the third connecting end. A portion of the third connecting end passes through the first adapter. The third connecting end is connected to a first nut and a second nut. The first nut and the second nut are located on opposite sides of the first adapter in the thickness direction of the first adapter. The third connecting end also includes a first heat insulation pad, which is disposed between at least one of the first nut and the second nut and the surface of the corresponding side of the first adapter.

[0012] By adopting this method, the heat transfer path between the first nut, the second nut, and the first adapter is at least partially or completely blocked, thereby reducing or preventing the heat transferred from the first adapter to the second section.

[0013] Optionally, the second fastener includes a second screw and a third nut adapted to the second screw, the second screw passing through the second adapter and the first adapter, the third nut located on the side of the second adapter away from the first adapter, and a second heat-insulating gasket disposed between the third nut and the second adapter; and / or,

[0014] The third nut is located on the side of the first adapter that is away from the second adapter, and a second heat insulation gasket is provided between the second nut and the first adapter.

[0015] This prevents the heat from the second screw from being transferred to the second or first adapter near the third nut via the third nut, thereby reducing or preventing heat transfer from the second screw to the second section.

[0016] Optionally, a third heat-insulating gasket is further provided between the second adapter and the first adapter, and the third heat-insulating gasket is sleeved on the second screw. This can prevent the second adapter and the first adapter from directly contacting each other and transferring heat.

One end of the third adapter is connected to the second adapter, and the other end is connected to the third coating.

[0018] A fourth heat-insulating gasket is provided between the third adapter and the second adapter. This prevents the third adapter from directly contacting the second adapter and causing heat transfer.

[0019] Optionally, a third fastener made of metal is included, comprising a third screw and a fourth nut; the third screw passes through the third adapter and the second adapter, the fourth nut presses against the side of the third adapter away from the second adapter, and a fifth heat-insulating gasket is provided between the fourth nut and the third adapter; and / or the fourth nut presses against the side of the second adapter away from the third adapter, and a fifth heat-insulating gasket is provided between the fourth nut and the second adapter. This prevents heat from the third screw from being transferred to the adjacent second or first adapter via the fourth nut.

[0026] This utility model provides a novel wall structure. By improving the wall structure, the thermal bridging effect of the anchors is ensured, while the load-bearing capacity of the anchors is improved, thereby enhancing the overall structural safety of the building.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the wall structure in an embodiment of this utility model; Figure 2 yes Figure 1 A magnified view of a portion of the image.

[0030] This utility model provides a wall structure, which includes a base wall layer 40, a first covering layer 41, and a first fastener 1. The first fastener 1 is used to connect the base wall layer 40 and the first covering layer 41. The first covering layer 41 can be a thermal insulation layer or a fireproof layer, etc. The first covering layer 41 has a first surface 411 and a second surface 412 that are disposed opposite to each other in the thickness direction of the wall structure. The first surface 411 is close to the base wall layer 40 and is spaced apart from or attached to the base wall layer 40. The second surface 412 is the surface away from the base wall layer 40.

[0031] The first fastener 1 is made of metal. In this embodiment, the traditional method of using plastic anchors is changed. By using a metal first fastener 1 as an anchor to connect the first cladding layer 41 and the base wall layer 40, the connection strength between the first cladding layer 41 and the base wall layer 40 is improved.

[0032] The first fastener 1 includes a first section 11, a second section 12, and a thermally insulating connector 14. The first section 11 and the second section 12 are arranged sequentially at intervals along the thickness direction of the wall structure to form a spacer 13. At least a portion of the first section 11 is fixed to the base wall layer 40. One end of the second section 12 extends to the side surface of the first covering layer 41 away from the base wall layer 40, i.e., the second surface 412, and abuts against the second surface 412. The first section 11 and the second section 12 are connected by the thermally insulating connector 14.

[0033] In one specific embodiment, as shown in the figure, the first section 11 is an expansion bolt, and the second section 12 is a metal screw. One end of the expansion bolt is located inside the base wall layer 40, and the other end is located inside the first covering layer 41, so that the first section 11 can connect the base wall layer 40 and the first covering layer 41. As a metal screw, one end of the second section 12 is located inside the first covering layer 41, and the other end extends to the outside of the second surface 412 and is threadedly connected to a first nut 1211, which is tightly abutted against the second surface 412. The first section 11 and the second section 12 are connected by a heat-insulating connector 14. A spacer 13 is also provided between the second section 12 and the first section 11 of the first fastener 1, thereby blocking the heat conduction between the first section 11 and the second section 12. This can firmly lock the first covering layer 41 to the base wall layer 40, while also blocking the heat conduction path between the first section 11 and the second section 12. The thermal insulation connector 14 is made of thermal insulation material, such as high-strength engineering plastics.

[0034] The portion of the first section 11 located inside the sleeve is defined as the first connecting end 111, and the portion of the second section 12 located inside the sleeve is defined as the second connecting end 122. The first connecting end 111 and the second connecting end 122 are arranged at intervals in the thickness direction of the wall structure to form a spacer 13. The first connecting end 111 and the second connecting end 122 are connected by a thermal insulation connector 14.

[0035] In an optional embodiment, the thermally insulating connector 14 includes a sleeve, one end of which is fitted onto the first end, and the other end of which is fitted onto the second end of the first segment 11. A spacer 13 is located inside the sleeve. By using a sleeve, the connection between the first segment 11 and the second segment 12 is achieved, and a spacer 13 is also provided in the middle of the sleeve. The spacer 13 contains gas that is sealed inside during installation, thereby further improving the thermal conductivity resistance between the first segment 11 and the second segment 12.

[0036] Of course, in addition to the tubular thermal insulation connector 14, it can also be a frame structure thermal insulation connector 14. Specifically, the frame structure can be quadrilateral or cylindrical, etc. As long as it can connect the first section 11 and the second section 12 while maintaining the gap 13 between the first section 11 and the second section 12, it is acceptable.

[0037] In one alternative implementation, the first connecting end 111 and the second connecting end 122 are threadedly connected to the sleeve. As shown in the figure, the inner wall of the sleeve has a threaded structure, and the outer walls of the first connecting end 111 and the second connecting end 122 also have matching threaded structures, thereby achieving a threaded connection between the first connecting end 111, the second connecting end 122, and the sleeve. This threaded connection improves the ease of operation when connecting the first section 11 and the second section 12. Of course, besides the threaded connection, the first connecting end 111, the second connecting end 122, and the sleeve can also be riveted, crimped, or otherwise connected via an interference fit.

[0038] Optionally, the radial dimensions of the portions of the first section 11 and the second section 12 that connect to the sleeve are the same. The radial dimensions of the first connecting end 111 and the second connecting end 122 are the same, which simplifies the processing and installation procedures.

[0039] In some other embodiments of this application, the wall structure further includes a second covering layer 42, which may be an insulation layer or a fireproof layer, etc., without specific limitations here. The second covering layer 42 is located on the side of the first covering layer 41 away from the base wall layer 40, that is, the second covering layer 42 is close to the second surface 412 of the first covering layer 41; the second covering layer 42 may be spaced apart from the second surface 412 or may be attached to the second surface 412.

[0040] A first adapter 51 is provided inside the first covering layer 41. The first adapter 51 can be pre-embedded inside the first covering layer 41 during the production process of the first covering layer 41, or it can be placed inside the first covering layer 41 during the installation process. In the example shown in the figure, the first adapter 51 is a plate-shaped structure and is arranged in the vertical direction, that is, perpendicular to the thickness direction of the wall structure. The first adapter 51 has a first connecting position and a second connecting position, and both the first connecting position and the second connecting position are provided with connecting holes.

[0041] The end of the second segment 12 that is furthest from the sleeve is defined as the third connecting end 123. A portion of the third connecting end 123 passes through the first connecting position of the first adapter 51. The third connecting end 123 is connected to a first nut 1211 and a second nut 1212, which are located on opposite sides of the first adapter 51 in the thickness direction. The third connecting end 123 passes through the connecting hole provided in the first connecting position to the outside of the second surface 412, and is pressed against the second surface 412 by the first nut 1211. In this embodiment, a first heat-insulating gasket 61 is provided between the first nut 1211 and the first connecting position. This prevents the heat from the first nut 1211 from being transferred to the first adapter 51 and then to the second segment 12 via the first adapter 51.

[0042] As an alternative, the third connecting end 123 is also provided with a second nut 1212, which is located on the side of the first adapter 51 away from the first nut 1211 and abuts against the first adapter 51; a first heat insulation gasket 61 is also provided between the second nut 1212 and the first adapter 51, thereby blocking the path of heat transfer to the second section 12.

[0043] The second cladding 42 is provided with a second adapter 52, which is connected to the second connection position of the first adapter 51 via a second fastener 2. The first adapter 51, the second adapter 52, and the second fastener 2 are all made of metal. The second fastener 2 is also a screw and nut structure. Specifically, the second fastener 2 includes a second screw 22 and a third nut 23 adapted to the second screw 22. The second screw 22 passes through the second connection position of the second adapter 52 and the first adapter 51. The third nut 23 is located on the side of the second adapter 52 away from the first adapter 51. A second heat insulation gasket 62 is provided between the third nut 23 and the second adapter 52. And / or, the third nut 23 is located on the side of the first adapter 51 away from the second adapter 52. A second heat insulation gasket 62 is provided between the second nut 1212 and the first adapter 51. This prevents the heat from the second screw 22 from being transferred to the second adapter 52 or the first adapter 51, which is close to the third nut 23, thereby reducing or preventing the heat from being transferred from the second screw 22 to the second section 12.

[0044] By adopting this method, the first coating 41 and the second coating 42 are connected by the first adapter 51, the first fastener 1, the second fastener 2 and the second adapter 52. The first adapter 51, the first fastener 1, the second fastener 2 and the first adapter 51 are all made of metal, which improves the connection strength between the first coating 41 and the second coating 42.

[0045] As an optional implementation, a third heat-insulating gasket 63 is further provided between the second adapter 52 and the first adapter 51, and the third heat-insulating gasket 63 is sleeved on the second screw 22. This can prevent the second adapter 52 and the first adapter 51 from directly contacting and transferring heat.

[0046] In some alternative embodiments, a third cladding layer 43 and a third adapter 53 are also included. The third cladding layer 43 is disposed on the side of the second cladding layer 42 away from the first cladding layer 41; the third adapter 53 is made of metal. One end of the third adapter 53 is connected to the second adapter 52, and the other end is connected to the third cladding layer 43; a fourth heat-insulating gasket 64 is disposed between the third adapter 53 and the second adapter 52. This prevents direct contact between the third adapter 53 and the second adapter 52, thus avoiding heat transfer.

[0047] Specifically, it also includes a third fastener 3 made of metal, which includes a third screw 33 and a fourth nut 34; the third screw 33 passes through the third adapter 53 and the second adapter 52, and the fourth nut 34 presses against the side of the third adapter 53 away from the second adapter 52, with a fifth heat insulation plate 65 provided between the fourth nut 34 and the third adapter 53; and / or the fourth nut 34 presses against the side of the second adapter 52 away from the third adapter 53, with a fifth heat insulation plate 65 provided between the fourth nut 34 and the second adapter 52. This prevents heat from the third screw 33 from being transferred to the adjacent second adapter 52 or first adapter 51 via the fourth nut 34.

[0048] In this embodiment, the screw mentioned can be a constant diameter screw or a T-shaped screw. The nut refers to the part connected to the screw and whose radial dimension is larger than that of the screw, including the large diameter end of the T-shaped screw. Therefore, in this solution, the nut and the shank of the screw can be connected by welding or by thread.
