Prefabricated buildings refer to buildings in which building components (such as walls, floor slabs, stairs, balconies, etc.) are prefabricated in factories and then transported to the site for assembly using reliable connection methods. Its core is "industrialized production and assembly-based construction," which has the characteristics of high efficiency, environmental protection, and controllable quality, and is an important development direction for the modernization of the construction industry.

[0003] Currently, external wall panel connection methods include welding, bolt connection, and self-locking dry connection. Although there are various nodes in the existing technology that can connect the external wall panel to the main structure and meet the three-dimensional adjustment during installation, such as the patent number 201911087046.0, which discloses a three-dimensional adjustable prefabricated lightweight strip wall system, although it can have three-dimensional adjustment performance during installation, it does not meet the vertical limiting function when used as a support connection node because its vertical support is achieved by bolts and elongated holes.

The third welded component is connected to the outer wall panel, and the diameter of the enlarged hole is larger than the diameter of the screw. The fourth welded component is connected to the main structure and is located below the third welded component. The fourth welded component includes a fourth base plate with a connecting hole.

[0015] Compared with the prior art, the support connection node and its connection components for green building exterior wall panels provided by this utility model have the following beneficial effects:

[0016] 1. The green building exterior wall panel support connection node and its connection components provided by this utility model are connected by a first bolt and a first threaded sleeve. The weight of the exterior wall panel is transferred to the first bolt through the first threaded sleeve. Then, the lower end of the first bolt abuts against the first base plate, and the first base plate is connected to the main structure. Thus, the weight of the exterior wall panel is transferred to the main structure in sequence through the first threaded sleeve, the first bolt, and the first base plate, thereby satisfying the vertical limiting function of the support connection node.

[0017] 2. The supporting connection node and its connecting components for green building exterior wall panels provided by this utility model are adjusted in the horizontal direction as follows: First, the first welded part and the second welded part are connected by threaded connection between the second threaded sleeve and the second bolt assembly. Then, the relative position of the first welded part and the second welded part in the horizontal direction is adjusted by rotating the second bolt of the second bolt assembly. After the horizontal position is adjusted, the second screw is locked by the second nut. The supporting connection node is adjusted in the horizontal direction as follows: The depth of the third bolt into the third threaded sleeve is adjusted by rotating the third bolt, which drives the second welded part to adjust its position in the horizontal direction. After the horizontal position is adjusted, the third screw is no longer rotated. The vertical position adjustment of the support connection node is specifically as follows: The depth of the first bolt inserted into the first threaded sleeve is adjusted by rotating the first bolt. Since the free end of the first bolt always rests against the upper surface of the first base plate, when the first bolt is rotated, the threaded engagement between the first bolt and the first threaded sleeve will cause the second welded part to adjust its relative position in the vertical direction relative to the first welded part. Once the vertical position adjustment is complete, the first bolt can be stopped from being rotated. When the aforementioned support connection node is adjusted in three dimensions, the horizontal adjustment structure in the first plane also includes an inverted U-shaped sliding piece located between the second nut and the corresponding first side plate. This sliding piece can adjust the installation accuracy and positional deviation, fill gaps, reduce on-site work, and speed up the installation process.

[0018] 3. The green building exterior wall panel support connection node and its connection components provided by this utility model, by laying polytetrafluoroethylene plates on the free end of the first bolt and the two end faces of the second end plate, can coordinate structural deformation, release stress and improve node durability through the characteristics of low friction, sliding and corrosion resistance, thereby ensuring a safe and reliable connection between the exterior wall panel and the main structure. It is especially suitable for prefabricated buildings with high requirements for earthquake resistance, wind resistance and long-term performance.

[0019] 4. The green building exterior wall panel support connection node and its connection components provided by this utility model have a three-dimensional adjustment function when the exterior wall panel is connected to the main structure. The fourth threaded sleeve, the enlarged hole, the fourth screw and the steel washer work together to achieve adjustment in the in-plane direction; the elongated hole, the connecting hole and the fifth bolt assembly work together to achieve adjustment in the out-of-plane direction; the second limiting clip, the fourth horizontal adjustment hole, the fifth threaded sleeve and the sixth bolt work together to achieve adjustment in the out-of-plane direction.

Detailed Implementation

[0029] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0030] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0031] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] In one embodiment, such as Figures 1-3 As shown, this embodiment discloses a specific implementation of a support connection node for green building exterior wall panels, which is used to connect exterior wall panel A to the main structure B. The support connection node for exterior wall panel A includes a first welded component connected to the main structure B, a second welded component connected to the exterior wall panel A, and a first bolt 3. Figure 1As shown, the first welded component includes a horizontally arranged first base plate 1a. The second welded component includes a horizontally arranged second base plate 2a and a first threaded sleeve 2b, with the second welded component located above the first welded component, i.e., the second base plate 2a is located above the first base plate 1a. A vertically penetrating first height adjustment hole is provided on the second base plate 2a. The first threaded sleeve 2b is vertically arranged on the upper end face of the second base plate 2a and coaxially arranged with the first height adjustment hole. The screw of the first bolt 3 is threadedly connected to the first threaded sleeve 2b, and the free end of the screw of the first bolt 3 passes through the first height adjustment hole and abuts against the upper end face of the first base plate 1a. Thus, the weight of the external wall panel A is sequentially transferred to the main structure B through the second base plate 2a, the first threaded sleeve 2b, the first bolt 3, and the first base plate 1a. Furthermore, the first base plate 1a can vertically lift the first bolt 3, thereby achieving a vertical limiting function. Meanwhile, when the support connection node is installed, rotating the first bolt 3 can adjust the relative position of the second welded part with respect to the first welded part in the vertical direction.

[0035] The supporting connection node for the green building exterior wall panel in this embodiment also includes a first in-plane horizontal adjustment structure and a first out-of-plane adjustment structure. The first welded component is adjusted horizontally with the second welded component within the plane via the first in-plane horizontal adjustment structure. The first welded component is adjusted out of plane with the second welded component via the first out-of-plane adjustment structure. As discussed above, this supporting connection node can achieve three-dimensional adjustment during the installation of the exterior wall panel A and the main structure B.

[0036] In one embodiment, such as Figure 1 As shown, along the out-of-plane direction, the first welded component also includes first side plates 1b vertically arranged on both sides of the first base plate 1a. Each first side plate 1b is provided with a first horizontal adjustment hole 1c that runs horizontally through it. The first horizontal adjustment holes 1c on the two first side plates 1b are arranged coaxially and horizontally.

[0037] Along the out-of-plane direction, the second welded component also includes a second side plate 2c that is vertically disposed on both sides of the second base plate 2a. The second side plate 2c is located between the two first side plates 1b, and each second side plate 2c is provided with a horizontally penetrating second horizontal adjustment hole 2d.

[0038] like Figures 1-3As shown, the aforementioned in-plane horizontal adjustment structure includes a second threaded sleeve 2e and a second bolt assembly. The two ends of the second threaded sleeve 2e are respectively connected to the second horizontal adjustment hole 2d on the corresponding side. In this embodiment, the two ends of the second threaded sleeve 2e are welded to the second horizontal adjustment hole 2d on the corresponding side. The second horizontal adjustment hole 2d and the second threaded sleeve 2e on the two second side plates 2c are coaxially and horizontally arranged. The second bolt assembly includes a second bolt 4a and a second nut 4b. The screw of the second bolt 4a is threadedly connected to the second threaded sleeve 2e and passes through the first horizontal adjustment hole 1c and the second horizontal adjustment hole 2d. The second nut 4b is connected to the free end of the screw of the second bolt 4a. The diameter of the first horizontal adjustment hole 1c is larger than the diameter of the screw of the second bolt 4a. Specifically, the middle part of the screw of the second bolt 4a is threadedly connected to the second threaded sleeve 2e, and the two ends of the screw of the second bolt 4a extend away from the second threaded sleeve 2e and pass through the second horizontal adjustment hole 2d and the first horizontal adjustment hole 1c on the corresponding side in sequence, so that the head of the second bolt 4a and the second nut 4b are located on both sides of the first welded part. After the support connection node is installed, the second bolt 4a can be locked by the second nut 4b.

[0039] When the external wall panel A is adjusted horizontally within a plane using the first in-plane horizontal adjustment structure—that is, when the external wall panel A and the main structure B need to be adjusted horizontally within a plane during installation—the first in-plane horizontal adjustment structure also includes an inverted U-shaped sliding piece 5. The sliding piece 5 is located between the second nut 4b and the corresponding first side plate 1b. In this embodiment, the inverted U-shaped sliding piece 5 is hooked onto the thread of the second bolt 4a. Furthermore, a steel washer 6 is provided between the sliding piece 5 and the first side plate 1b.

[0040] In one embodiment, such as Figures 1-3 As shown, along the out-of-plane direction, the first welded component further includes a first end plate (not shown in the figure) perpendicularly disposed at the end of the first base plate 1a near the main structure B. This first end plate is welded to the main structure B, and the first end plate has a third threaded sleeve 1d extending perpendicularly toward the outer wall panel A. In other embodiments, the first end plate and the main structure B may also be integrally formed or otherwise fixedly connected, which will not be elaborated here. Along the out-of-plane direction, the second welded component further includes a second end plate 2f perpendicular to the end of the second base plate 2a near the main structure B.

[0041] The first out-of-plane adjustment structure includes an adjustment structure that can be vertically adjusted relative to the second end plate 2f. The adjustment structure is threadedly connected to the third threaded sleeve 1d by the third bolt 7. Rotating the third bolt 7 can drive the second welded part to adjust its position along the horizontal outward direction.

[0042] Specifically, such as Figures 1-3 As shown, the adjustment structure is a first limiting clamp 8, which includes a first straight plate 8a and a first inverted L-shaped plate 8b. One end of the first inverted L-shaped plate is welded to the first straight plate 8a, so that the cross-section of the first limiting clamp 8 is h-shaped. A first groove is formed between the first straight plate 8a and the first inverted L-shaped plate 8b. The first limiting clamp 8 is clamped at the upper end of the second end plate 2f through the first groove. The first limiting clamp 8 can adjust its relative position with the second end plate 2f in the vertical direction.

[0043] A third horizontal adjustment hole is provided on the first straight plate 8a. The third horizontal adjustment hole is located above the first inverted L-shaped plate 8b. The screw of the third bolt 7 passes through the third horizontal adjustment hole and is threadedly connected to the third threaded sleeve 1d. By rotating the third bolt 7, its depth of insertion into the third threaded sleeve 1d can be adjusted, thereby realizing the relative position of the first welded part with respect to the second welded part in the out-of-plane direction.

[0044] Better, such as Figure 2 As shown, along the out-of-plane direction, both end faces of the second end plate 2f are covered with polytetrafluoroethylene (PTFE) plates 9. Through their low friction, sliding, and corrosion-resistant properties, they coordinate structural deformation, release stress, and improve node durability. They are especially suitable for prefabricated buildings with high requirements for earthquake resistance, wind resistance, and long-term performance.

[0045] More preferably, in one embodiment, such as Figure 2 As shown, a polytetrafluoroethylene (PTFE) plate 9 is laid on the free end of the screw of the first bolt 3. The function of the PTFE plate 9 is the same as that of the PTFE plate 9 at the second end plate 2f, which will not be described in detail here.

[0046] In one embodiment, a connection component is disclosed, including a support connection node and a limiting connection node for green building exterior wall panels as described above. Specifically, such as Figure 5 As shown, a fourth threaded sleeve 16 is embedded in the outer wall panel A at the position corresponding to the limiting connection node. Figure 4 As shown, the limiting connection node includes a third welded component, a fourth bolt 12, a steel washer 6, a fourth welded component connected to the main structure B, and a fifth bolt assembly 13.

[0047] like Figures 4-6As shown, the third welded component includes a third base plate 10a. Along the out-of-plane direction, a third end plate 10b is vertically provided at one end of the third base plate 10a near the outer wall panel A. The third end plate 10b has an enlarged hole 10e. An elongated hole 10f extending along the out-of-plane direction is provided on the third base plate 10a. The bolt 12 passes through the steel washer 6 and the enlarged hole 10e in sequence and is threaded into the fourth threaded sleeve 16 to connect the third welded component to the outer wall panel A. The diameter of the enlarged hole 10e is larger than the bolt diameter. The fourth welded component includes a fourth base plate 11a, which has a connecting hole. The fourth welded component is located below the third welded component, i.e., the fourth base plate 11a is located below the third base plate 10a. Figure 5 As shown, the fifth bolt assembly 13 includes a fifth bolt 13a and a fifth nut 13b. The fifth nut 13b is located at the bottom of the fourth base plate 11a at the position corresponding to the connecting hole. The thread of the fifth bolt 13a passes through the elongated hole 10f and the connecting hole from top to bottom and is threadedly connected to the fifth nut 13b. Specifically, a steel washer 6 is also provided at the fifth bolt assembly 13.

[0048] When the limiting connection node is installed, its position in the out-of-plane direction is adjusted by adjusting the position of the fifth bolt 13a on the elongated hole 10f. When adjustment in the in-plane direction is required, the fourth bolt 12 can be rotated appropriately, and then the position of the third welded component relative to the outer wall panel A in the in-plane direction can be adjusted. The adjustable range in the in-plane direction depends on the diameter of the enlarged hole 10e; the larger the diameter, the greater the adjustable range. After adjustment, tighten the fourth bolt 12. Therefore, as described above, the limiting connection node has a three-dimensional adjustment function during installation.

[0049] In one embodiment, such as Figures 3-6 As shown, along the out-of-plane direction, the third base plate 10a has a fourth end plate 10c perpendicularly installed at the end away from the outer wall panel A.

[0050] The limiting connection node also includes a second limiting clamp 15, which includes a second straight plate and a second inverted L-shaped plate. One end of the second inverted L-shaped plate is welded to the second straight plate, making the cross-section of the second limiting clamp 15 h-shaped. A second groove is formed between the second straight plate and the second inverted L-shaped plate. The second limiting clamp 15 is engaged with the upper end of the fourth end plate 10c through the second groove. The relative position of the second limiting clamp 15 and the fourth end plate 10c can be adjusted in the vertical direction. In this embodiment, more preferably, polytetrafluoroethylene (PTFE) plates can also be laid on both ends of the fourth end plate 10c, which has the same function as the aforementioned PTFE plates and will not be described again here.

[0051] like Figure 4As shown, the fourth welded component also includes a fifth end plate (not shown in the figure) which is vertically disposed at one end of the fourth base plate 11a near the main structure B. The fifth end plate is welded to the main structure B, and a fifth threaded sleeve 11b is vertically disposed on the fifth end plate extending in a direction away from the main structure B.

[0052] The limiting connection node also includes a sixth bolt 14 and a fourth horizontal adjustment hole opened on the second straight plate. The fourth horizontal adjustment hole is located above the second inverted L-shaped plate. The screw of the sixth bolt 14 passes through the fourth horizontal adjustment hole and is threadedly connected to the fifth threaded sleeve 11b. By rotating the sixth bolt 14, the depth of insertion into the fifth threaded sleeve 11b can be adjusted, thereby realizing the position adjustment of the limiting connection node in the out-of-plane direction.

[0053] When the upper part of the external wall panel A is connected to the main structure B through two supporting connection nodes, and the lower part of the external wall panel A is connected to the main structure B through two limiting connection nodes, and the two supporting connection nodes and the two limiting connection nodes are staggered in the horizontal direction, the connection process between the external wall panel A and the main structure B is discussed below:

[0054] 1. The outer wall panel A is lifted by a tower crane, wherein the second welding component has been welded to the outer wall panel A in the factory;

[0055] 2. Screw the first bolt 3 into the first threaded sleeve 2b, and screw the fourth bolt 12 through the enlarged hole 10e into the fourth threaded sleeve 16, keeping the fourth bolt 12 in a loose state.

[0056] 3. Hang the external wall panel A on the main structure B. At this time, the second welded part is placed on the first base plate 1a of the first welded part by the first bolt 3, and the third base plate 10a of the third welded part is placed on the fourth base plate 11a of the fourth welded part. Then install the second bolt assembly, the fifth bolt 13a, the steel washer 6 and the sliding piece 5, and then remove the hook.

[0057] 4. Install the first limiting clip 8, the second limiting clip 15, the third bolt 7, and the sixth bolt 14 to achieve connection in the out-of-plane direction;

[0058] 5. Perform positioning adjustment of the external wall panel A in the plane: Rotate the first bolt 3 as needed to adjust the fine adjustment of the external wall panel A in the vertical direction in the plane; rotate the second bolt 4a as needed to drive the second threaded sleeve 2e to perform fine adjustment in the horizontal direction in the plane; correspondingly, since the fourth bolt 12 is not tightened, the fourth bolt 12 can also be adjusted to its position in the enlarged hole 10e to achieve synchronous position adjustment of the limit connection node;

[0059] 6. Adjust the out-of-plane positioning of the external wall panel A: Rotate the third bolt 7 and the sixth bolt 14 as needed, and then adjust the position of the external wall panel A in the out-of-plane direction through the first limiting clip 8 and the second limiting pull clip respectively;

[0060] 7. Remove the aforementioned sliding piece 5 and tighten the second nut 4b and continue to tighten the fourth bolt 12 to complete the position fixation in the in-plane direction. Continue to rotate the fifth bolt 13a so that the fifth nut 13b locks the fifth bolt 13a, thereby achieving the position fixation in the out-of-plane direction.
