Description
Technical Field
[0001] This utility model relates to the field of connection structures, and further to connectors, connection components, and thermal insulation walls including connectors or connection components. Background Technology
[0002] Green building refers to buildings that maximize resource conservation throughout their entire life cycle, including energy conservation, land conservation, water conservation, and material conservation, while protecting the environment and reducing pollution. They provide people with healthy, comfortable, and efficient living spaces and coexist harmoniously with nature. Green building is one of the national directions in the field of architecture.
[0003] To secure the inner leaf plate, insulation board, and outer leaf plate of a sandwich insulated wall, two traditional stainless steel connectors are used. The first is the German-made sheet-type stainless steel connector. Specifically, this connector is anchored at the ends of the inner and outer leaf plates using steel bars inserted at the ends. This leads to localized thermal bridges within the connector, resulting in poor energy efficiency. The second is the Finnish truss-type stainless steel connector. This connector uses threaded steel for the upper and lower straight ribs and stainless steel for the chords. This also presents localized thermal bridges, leading to poor energy efficiency. Furthermore, both types of stainless steel connectors require a relatively large amount of steel to achieve the required mechanical properties. Utility Model Content
[0004] The purpose of this utility model is to provide a connector, a connecting component, and an insulated wall including the connector or the connecting component, to solve the technical problem of poor energy-saving effect caused by thermal bridges at the connector in the prior art, to avoid thermal bridges, to achieve better energy-saving effect, and at the same time reduce the overall steel consumption, lower cost and reduce carbon emissions.
[0005] To achieve the above objectives, this utility model provides a connector for use in non-combined sandwich insulated walls. The non-combined sandwich insulated wall includes an inner leaf plate, an insulation board, and an outer leaf plate stacked sequentially from the inside to the outside. It comprises: a first part located within the outer leaf plate, a second part located within the insulation board, and a third part located within the inner leaf plate, connected sequentially. The first and second parts are covered by a thermal break material to avoid thermal bridging at the first and second parts. The second part includes two second connecting rods connected to each other in a cross configuration. The first end of each second connecting rod is connected to the third part, and the second end of each second connecting rod is connected to the first part.
[0006] In some embodiments, the thermal break material is fiber-reinforced polyamide plastic, polyethylene, or polypropylene.
[0007] In some embodiments, the third part includes two parallel first connecting rods, with the first connecting rods being perpendicular to the plane of the inner leaf plate. The first connecting rods are provided with a connecting structure for anchoring the third part to the inner leaf wall. The second ends of the first connecting rods are connected one-to-one to the first ends of the second connecting rods. The second part is symmetrical along a first axis of symmetry, which is parallel to the first connecting rods and passes through the intersection of the two second connecting rods.

[0009] In some embodiments, the first part includes a third connecting rod, the two ends of which are respectively connected to the second ends of the two second connecting rods.
[0010] In some embodiments, the first part includes two parallel third connecting rods, one end of which is connected to the second end of the second connecting rod and the third connecting rod is perpendicular to the second connecting rod, and the free ends of the two third connecting rods extend in opposite directions.
[0011] This utility model also discloses a connecting component, including the aforementioned connecting member, and further including: two positioning clips disposed in the outer leaf plate, the positioning clips including a first straight plate and a limiting structure disposed on the first straight plate, the plane of the first straight plate being parallel to the plane of the outer leaf plate, and the limiting structure contacting the third connecting rod and preventing the third connecting rod from being exposed on the end face of the outer leaf plate away from the insulation board.
[0012] In some embodiments, the limiting structure includes a second straight plate and a third straight plate, the second end of the second straight plate being connected to the first end of the third straight plate, the first end of the second straight plate being connected to the first end of the first straight plate, and the second end of the third straight plate being connected to the second end of the first straight plate; the limiting structure also includes a first through hole extending from the second straight plate to the third straight plate, thereby forming a first engaging portion on the limiting structure for engaging the connection between the third connecting rod and the second connecting rod; or; the limiting structure includes an arc-shaped rod and an annular body connected to the first straight plate, the opening of the arc-shaped rod facing upward and located between the first straight plate and the annular body, the annular body having an opening; when the connecting member is installed in the positioning clip, the third connecting rod passes through the opening of the annular body and is placed in the opening of the arc-shaped rod.
[0013] In some embodiments, the limiting structure includes a fourth straight plate and a fifth straight plate that are parallel to each other. The fourth straight plate and the fifth straight plate are both vertically connected to the first straight plate, and one of the corresponding ends of the fourth straight plate and the fifth straight plate are connected by a sixth straight plate. The fourth straight plate, the fifth straight plate, the first straight plate and the sixth straight plate together form a second snap-fit portion for placing the connection between the third connecting rod and the second connecting rod.
[0014] This utility model also discloses an insulated wall, comprising an inner leaf plate, an insulation board, an outer leaf plate, and the aforementioned connectors stacked sequentially from the inside to the outside; or; an inner leaf plate, an insulation board, an outer leaf plate, and the aforementioned connecting components stacked sequentially from the inside to the outside.
[0015] Compared with the prior art, the connectors, connecting components, and thermal insulation walls including the connectors or connecting components provided by this utility model have the following beneficial effects:
[0016] 1. The connectors, connecting components, and insulated walls including the connectors or connecting components provided by this utility model, by covering the outer sides of the first and second parts with a layer of thermal break material, can avoid thermal bridging at the first and second parts, thus improving the energy-saving performance of the wall. Simultaneously, due to the cross-shaped structure of the second part, it connects with the inner and outer leaf plates to form a spatial truss structure, enhancing the overall rigidity of the wall and fully utilizing the tensile and compressive strength of stainless steel. Compared to existing German sheet-type and Finnish truss-type stainless steel connectors, this invention achieves the same mechanical performance while reducing overall steel consumption, lowering costs, and reducing carbon emissions.
[0017] 2. The connector, connecting assembly, and insulated wall including the connector or connecting assembly provided by this utility model, when the first part includes only one third connecting rod, the two ends of which are respectively connected to the second ends of two second connecting rods, thereby forming a closed shape at one end of the connector. When it is set on the outer leaf plate, the closed part of the connector can be tied to the reinforcing steel of the outer leaf plate, thereby improving the anchorage performance of the connector on the outer leaf plate and solving the pull-out failure caused by insufficient anchorage between the connector and the outer leaf wall panel under wind load and seismic load during normal use and demolding load during the prefabrication stage. When the first part consists of two parallel third connecting rods, two additional tail reinforcing steel bars are needed to tie them to the reinforcing steel of the outer leaf plate to achieve anchorage performance.
[0018] 3. The connectors, connecting components, and insulated walls including the connectors or connecting components provided by this utility model, in the actual manufacturing process, firstly, the first part is prefabricated inside the outer leaf plate, and then the insulation board blocks are placed on the connectors from top to bottom. At this time, since the first connecting rod is perpendicular to the insulation board, it is easier for the first connecting rod to penetrate into the insulation board. As the insulation board gradually approaches the outer leaf plate, the two cross-shaped second connecting rods will gradually cut the insulation board at the corresponding positions, so that the insulation board is finally laid on the outer leaf plate. Finally, the inner leaf plate is prefabricated on the insulation board, thus prefabricating the third part on the inner leaf plate. However, the existing German sheet-type stainless steel connectors and Finnish truss-type stainless steel connectors require the insulation board to be cut in advance during the prefabrication of the insulated wall, which increases the difficulty of the insulation board layout and easily forms gaps at the connectors. If the gaps are filled with concrete or other foam insulation materials, the energy-saving performance of the insulated wall will be affected. On the one hand, the insulation wall of this utility model only requires cutting the insulation board at the corresponding position using connectors when installing the insulation board, making the placement of the insulation board easier and the construction more convenient, thus improving the construction efficiency of the insulation wall. On the other hand, the insulation wall of this utility model has superior energy-saving performance.
[0019] 4. The connector, connecting assembly, and thermal insulation wall including the connector or connecting assembly provided by this utility model have the end of the first connecting rod anchored in the inner leaf plate in a point-like manner, which reduces the collision between the rod and the steel bars or other embedded parts of the inner leaf plate and improves the construction efficiency of the wall.
[0020] 5. The connectors, connecting components, and insulated walls including connectors or connecting components provided by this utility model, in the process of prefabricating the first part inside the outer leaf plate, by first placing the positioning clips on the template and then placing the first part on the positioning clips, can prevent the connectors from tipping over during pouring or prevent the first part from being exposed outside the outer leaf plate after prefabrication, thus avoiding the risk of corrosion during long-term use.

[0046]
Example 1
[0047] like Figure 1 As shown, this embodiment discloses a specific implementation of a connector applied to a non-combined sandwich insulated wall. The non-combined sandwich insulated wall includes an inner leaf plate, an insulation board, and an outer leaf plate stacked sequentially from the inside to the outside. The connector is used to connect the inner leaf plate, the insulation board, and the outer leaf plate together. Specifically, the connector is made of stainless steel and includes a first part located inside the outer leaf plate, a second part located inside the insulation board, and a third part located inside the inner leaf plate, which are connected sequentially. The first part and the second part are covered by a thermal break material to avoid forming a thermal bridge at the first part and the second part. The thermal break material is a fiber-reinforced polyamide plastic with low thermal conductivity and high plasticity.
[0048] In other embodiments, the thermal break material may also be polyethylene or polypropylene, which will not be described in detail here.
[0049] like Figure 1 As shown, the second part includes two second connecting rods 2, which are connected to each other in a cross configuration. The first end of the second connecting rod 2 (i.e. Figure 1 The upper end of the second connecting rod 2) is connected to the third part, and the second end of the second connecting rod 2 (i.e. Figure 1 The lower end of the second connecting rod 2 is connected to the first part. In this embodiment, the two second connecting rods 2 can be located on the same plane or stacked together, which will not be described in detail here.
[0050] In this embodiment, by covering the outer sides of the first and second parts with a layer of thermally broken material, thermal bridges can be avoided at the first and second parts, thus improving the energy-saving performance of the wall. Simultaneously, due to the cross-shaped structure at the second part, it connects with the inner and outer leaf plates to form a spatial truss structure, enhancing the overall rigidity of the wall and fully utilizing the tensile and compressive strength of stainless steel. Compared to existing German sheet-type and Finnish truss-type stainless steel connectors, this method achieves the same mechanical performance while reducing steel consumption, lowering costs, and reducing carbon emissions.
[0051] like Figure 1 As shown, the third part includes two parallel first connecting rods 1, with the first connecting rods 1 perpendicular to the plane of the inner leaf plate. The first connecting rods 1 are provided with a connecting structure 1a that anchors the third part to the inner leaf wall. The second end of the first connecting rod 1 (i.e., Figure 1 The lower end of the first connecting rod 1 is connected to the first end of the second connecting rod 2 in a one-to-one correspondence, and the second part is symmetrical along the first axis of symmetry, which is parallel to the first connecting rod 1 and passes through the intersection point 2a of the two second connecting rods.
[0052] In this embodiment, as Figure 1 As shown, the two second connecting rods 2 are at a preset angle A. This preset angle A can be designed according to the actual stress requirements of the wall. However, depending on the preset angle A, the position of the intersection point 2a of the two second connecting rods will change accordingly. Figures 5-6 .
[0053] In this embodiment, the connecting structure 1a is disposed at the first end of the first connecting rod 1 (i.e., Figure 1 The external thread at the upper end of the first connecting rod 1 will be matched with the internal thread in the inner blade plate after the inner blade plate is prefabricated, thereby realizing the concave-convex fit between the concrete part of the inner blade plate and the connecting structure 1a, and thus realizing the firm anchoring of the two.
[0054] The end of the first connecting rod 1 is anchored in the inner leaf plate in a point-like manner to reduce its collision with the steel bars 5 or other embedded parts of the inner leaf plate and improve the construction efficiency of the wall.
[0055] In other embodiments, the connecting structure 1a may also be a bent rod disposed at the first end of the first connecting rod 1, the axis of the bent rod being at a preset angle to the axis of the first connecting rod 1; an anchor plate disposed at the first end of the first connecting rod 1; a protrusion formed by upsetting at the first end of the first connecting rod 1; or a wavy connecting portion formed at the middle position of the first connecting rod 1. See details below. Figure 9 These structures can also form a convex-concave fit with the inner blade plate after the inner blade plate is prefabricated, thereby achieving a firm anchoring connection.
[0056] This embodiment also discloses an insulated wall, which is a non-composite sandwich insulated wall, such as... Figure 2 As shown, it includes an inner leaf plate, an insulation plate, an outer leaf plate, and a connector in this embodiment, which are stacked sequentially from the inside to the outside.
[0057] The method for prefabricating the connectors within the insulated wall in this embodiment is as follows: First, the first part is prefabricated inside the outer leaf plate. Then, the insulation board blocks are placed on the connectors from top to bottom. Since the first connecting rod is perpendicular to the insulation board, it is easier for the first connecting rod to penetrate into the insulation board. As the insulation board gradually approaches the outer leaf plate, the two cross-shaped second connecting rods gradually cut the corresponding parts of the insulation board, ultimately allowing the insulation board to be laid on the outer leaf plate. Finally, the inner leaf plate is prefabricated on the insulation board, thereby prefabricating the third part on the inner leaf plate, thus completing the prefabrication process of the insulated wall. In contrast, the existing German sheet-type stainless steel connectors and Finnish truss-type stainless steel connectors require pre-cutting of the insulation board during the prefabrication of the insulated wall, increasing the difficulty of insulation board layout and easily creating gaps at the connector locations. If these gaps are filled with concrete or other foam-type insulation materials, the energy-saving performance of the insulated wall will be affected. On the one hand, the insulation wall of this utility model only requires cutting the insulation board at the corresponding position using connectors when installing the insulation board, making the placement of the insulation board easier and the construction more convenient, thus improving the construction efficiency of the insulation wall. On the other hand, the insulation wall of this utility model has superior energy-saving performance.
[0058]
Example 2
[0059] Example 2 discloses another specific implementation of the connector. Example 2 is based on Example 1, such as... Figure 1 or Figure 5 As shown, the first part includes a third connecting rod 3, the two ends of which are respectively connected to the second ends of two second connecting rods 2, thereby forming a closed shape at one end of the connector.
[0060] like Figure 2 or Figure 6 As shown, this embodiment also discloses an insulated wall, which includes an inner leaf plate, an insulation board, an outer leaf plate, and a connector in this embodiment, stacked sequentially from the inside to the outside. When the connector is installed on the outer leaf plate, the closed end of the connector can be tied to the reinforcing bar 4 of the outer leaf plate, thereby improving the anchorage performance of the connector on the outer leaf plate and solving the pull-out failure caused by insufficient anchorage between the connector and the outer leaf wall plate under wind load and seismic load during normal use, and demolding load during the prefabrication stage.
[0061]
Example 3
[0062] Example 3 discloses another specific implementation of the connector. Example 3 is based on Example 1, such as... Figure 3 or Figure 7 As shown, the first part includes two parallel third connecting rods 3, one end of each third connecting rod 3 being connected one-to-one to the second end of the second connecting rod 2 (i.e., Figure 3 or Figure 5 The lower end of the second connecting rod 2) and the third connecting rod 3 are perpendicular to the second connecting rod 2. The free ends of the two third connecting rods 3 extend in opposite directions, thereby forming an open shape at one end of the connector.
[0063] like Figure 4 or Figure 8 As shown, this embodiment also discloses an insulated wall, which includes an inner leaf plate, an insulation board, an outer leaf plate, and a connector in this embodiment, stacked sequentially from the inside to the outside.
[0064] At this point, two additional tail steel bars (not shown in the figure) can be added to tie the steel bar 4 of the outer leaf plate, thereby achieving anchorage performance and improving the anchorage performance of the connector on the outer leaf plate. This solves the pull-out failure of the connector and the outer leaf wall plate caused by insufficient anchorage under wind load and seismic load during normal use and demolding load during the prefabrication stage.
[0065]
Example 4
[0066] Example 4 discloses a specific implementation of a connecting component. Based on the connecting component shown in Example 2 or 3, Example 4 further includes two positioning clips 6 disposed within the outer leaf plate. In this example, the positioning clips 6 are made of plastic. Each positioning clip 6 includes a first straight plate 6a and a limiting structure disposed on the first straight plate 6a. The plane of the first straight plate 6a is parallel to the plane of the outer leaf plate, and the limiting structure contacts the third connecting rod and prevents the third connecting rod from being exposed on the end face of the outer leaf plate away from the insulation board.
[0067] Specifically, such as Figure 10 As shown, the limiting structure includes a second straight plate 6b and a third straight plate 6c, and the second end of the second straight plate 6b (i.e. Figure 10 The upper end of the second straight plate 6b) and the first end of the third straight plate 6c (i.e. Figure 10 The upper end of the third straight plate 6c is connected to the first end of the second straight plate 6b (i.e., the upper end of the third straight plate 6c). Figure 10 The lower end of the second straight plate 6b is connected to the first end of the first straight plate 6a, and the second end of the third straight plate 6c (i.e. Figure 10 The lower end of the third straight plate 6c is connected to the second end of the first straight plate 6a.
[0068] Furthermore, the limiting structure also includes a first through hole 6d, which extends from the second straight plate 6b to the third straight plate 6c, thereby forming a first locking part on the limiting structure for locking the connection between the third connecting rod 3 and the second connecting rod 2.
[0069] like Figure 11 As shown in the figure, this embodiment also discloses an insulated wall, including an inner leaf plate, an insulation board, an outer leaf plate, and a connecting component shown in this embodiment, which are stacked sequentially from the inside to the outside.
[0070] When the connector is placed on the template by the positioning clip 6, the lower end face of the first straight plate 6a is placed directly on the template, and the connection between the third connecting rod 3 and the second connecting rod 2 is placed in the first snap-fit part on the corresponding side.
[0071] The positioning clip 6 can prevent the connector from tipping over during the casting of the outer blade plate or prevent the first part of the connector from being exposed on the outer blade plate after prefabrication, which would pose a risk of corrosion with long-term use.
[0072]
Example 5
[0073] Example 5 discloses another specific implementation of the connecting component. The structure of Example 5 is basically the same as that of Example 4, except that the limiting structure is different.
[0074] Specifically, such as Figure 12 As shown, the limiting structure includes an arc-shaped rod 6f and an annular body 6e connected to the first straight plate 6a. The opening of the arc-shaped rod 6f faces upward and is located between the first straight plate 6a and the annular body 6e. The annular body 6e has an opening, which is located above the opening of the arc-shaped rod 6f.
[0075] Specifically, the annular body 6e is arranged parallel to the first straight plate 6a, and the annular body 6e is connected to the first straight plate 6a by a vertically arranged straight rod on the other side of its opening.
[0076] During the process of installing the connector into the positioning clip 6, the third connecting rod 3 passes vertically downward through the opening of the annular body 6e and is placed inside the opening of the arc-shaped rod 6f.
[0077] like Figure 13 As shown in the figure, this embodiment also discloses an insulated wall, including an inner leaf plate, an insulation board, an outer leaf plate, and a connecting component shown in this embodiment, which are stacked sequentially from the inside to the outside.
[0078]
Example 6
[0079] Example 6 discloses another specific implementation of the connecting component. The structure of Example 6 is basically the same as that of Example 4, except that the limiting structure is different and it is only applicable to the connecting component disclosed in Example 2.
[0080] Specifically, such as Figure 14 or Figure 16As shown, the limiting structure includes a fourth straight plate 6g and a fifth straight plate 6h that are parallel to each other. Both the fourth straight plate 6g and the fifth straight plate 6h are perpendicularly connected to the first straight plate 6a, and one of the corresponding ends of the fourth straight plate 6g and the fifth straight plate 6h is ( Figure 14 and Figure 16 The right ends of the fourth straight plate 6g and the fifth straight plate 6h are connected by the sixth straight plate 6i. The fourth straight plate 6g, the fifth straight plate 6h, the first straight plate 6a and the sixth straight plate 6i together form the second snap-fit part for placing the connection between the third connecting rod 3 and the second connecting rod 2.
[0081] When the connector is placed on the template by the positioning clip 6, the lower end face of the first straight plate 6a is placed directly on the template, and the connection between the third connecting rod 3 and the second connecting rod 2 is placed in the second snap-fit part on the corresponding side.
[0082] like Figure 15 or Figure 17 As shown in the figure, this embodiment also discloses an insulated wall, including an inner leaf plate, an insulation board, an outer leaf plate, and a connecting component shown in this embodiment, which are stacked sequentially from the inside to the outside.
[0083] It should be noted that the positioning card 6 disclosed in Embodiments 4 and 5 can be used with the connectors in Embodiments 2 (i.e., one end of the connector forms a closed shape) and 3 (i.e., one end of the connector forms an open shape), but the positioning card 6 disclosed in Embodiment 6 can only be used with the connector in Embodiment 2 (i.e., one end of the connector forms a closed shape), which will not be described again here.
