Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a prefabricated building curtain wall structure. Background Technology

[0002] Building curtain walls are a widely used external envelope system in modern high-rise and large buildings. Unlike traditional load-bearing exterior walls, they are non-load-bearing exterior wall systems suspended or supported outside the main building structure (such as beams, columns, and floor slabs). The core value of curtain walls lies in providing physical protection (such as wind and rain protection, thermal insulation, and sound insulation) and aesthetic expression for the building, while not bearing the load of the main structure.

[0003] Currently, the main load-bearing keel (columns) of the curtain wall are fixed to the beams, columns, or shear walls of the main structure via connectors (usually called "supports" or "adapters"). However, due to the fixed structure of the connectors, sufficient working space cannot be provided when the building curtain wall is replaced later, increasing the technical difficulty of subsequent inspection and maintenance. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a prefabricated building curtain wall structure that utilizes the expansion and contraction characteristics of the first connecting component to provide sufficient working space for the replacement of the building curtain wall in the later stage, thereby facilitating subsequent maintenance.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a prefabricated building curtain wall structure, comprising: a first connecting assembly, a second connecting assembly, and a curtain wall. The first connecting assembly includes a first groove, a second groove, a third groove, two limiting members, and two locking members. The first groove, the second groove, and the third groove are pivotally connected by a rotating shaft. The outer diameter of the second groove is smaller than the inner diameter of the first groove, and the inner diameter of the second groove is larger than the outer diameter of the third groove. The two limiting members and the two locking members are respectively disposed on the corresponding first groove, second groove, and third groove. The second connecting assembly is disposed between the third groove and the curtain wall.

[0007] In addition, the prefabricated building curtain wall structure proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, each of the two limiting members includes a guide groove and a rod. The two guide grooves are respectively opened on the second groove and the third groove, and the two rods are respectively disposed in the second groove, with the rods passing through the guide grooves.

[0009] Specifically, each of the two locking members includes a first through hole and a boss, wherein the two first through holes are respectively opened on the first groove and the second groove, and the two bosses are respectively disposed on the second groove and the third groove.

[0010] Specifically, the length of the second groove is less than that of the first groove, and the first groove is provided with fastening bolts.

[0011] Specifically, two second through holes are symmetrically opened on the first groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The prefabricated building curtain wall structure of the present invention, by pivotally connecting the first groove, the second groove and the third groove together, can be stacked or extended, thereby providing sufficient working space around the building curtain wall during maintenance, thus facilitating subsequent maintenance.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] The prefabricated building curtain wall structure of this utility model is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the prefabricated building curtain wall structure of this utility model embodiment may include: a first connecting component 1, a second connecting component 2, and a curtain wall 3.

[0023] The first connecting component 1 includes a first groove 11, a second groove 12, a third groove 13, two limiting members 14, and two locking members 15.

[0024] The first groove 11, the second groove 12 and the third groove 13 are pivotally connected by a rotating shaft. The outer diameter of the second groove 12 is smaller than the inner diameter of the first groove 11, and the inner diameter of the second groove 12 is larger than the outer diameter of the third groove 13.

[0025] It should be noted that the second groove 12 can be screwed into the interior of the first groove 11, and the third groove 13 can be screwed into the interior of the second groove 12.

[0026] Two limiting members 14 and two locking members 15 are respectively provided on the corresponding first groove 11, second groove 12 and third groove 13. It should be noted that the limiting members 14 are used to limit the rotation angle between the first groove 11 and the second groove 12 and the second groove 12 and the third groove 13, and the locking members 15 are used to lock the three when the first groove 11, the second groove 12 and the third groove 13 are retracted.

[0027] The second connecting component 2 is disposed between the third channel 13 and the curtain wall 3.

[0028] It should be noted that the second connecting component 2 and the third groove 13 described in this embodiment can be connected by a detachable connection, thereby facilitating the installation of the curtain wall 3.

[0029] Specifically, in the initial stage of installation of this prefabricated building curtain wall, the second connecting component 2 is connected to the curtain wall 3 by means of composite adhesive bonding, the first groove 11 is fixed in the preset position of the main structure (e.g., shear wall), and then the third groove 13 is connected to the second connecting component 2.

[0030] When the curtain wall 3 is pushed, the first groove 11, the second groove 12 and the third groove 13 are stacked together, and the locking member 15 fixes the three in pairs. After the multiple curtain walls 3 are installed, a sealing strip or sealant is injected between two adjacent curtain walls 3.

[0031] When the building curtain wall needs to be replaced later, relevant technicians will work from a height to break the sealing strips or sealant around the curtain wall 3. They will then use suction cups to pull the curtain wall 3. Under the action of external force, the first groove 11, the second groove 12 and the third groove 13 will extend. The limiting member 14 will limit the rotation angle of the three. When the three rotate to their limit, they can provide temporary support for the curtain wall 3. The curtain wall 3 extends a certain distance relative to the plane of other building curtain walls, so that the building curtain wall can provide sufficient working space around it during maintenance, thus facilitating subsequent maintenance.

[0032] In one embodiment of this utility model, such as Figure 2 As shown, the two limiting members 14 respectively include a guide groove 141 and a rod 142.

[0033] Two guide grooves 141 are respectively opened on the second groove 12 and the third groove 13, and two rods 142 are respectively set in the second groove 12, with the rods 142 passing through the guide grooves 141.

[0034] It should be noted that when the second groove 12 and the third groove 13 rotate, the rod 142 can move within the guide groove 141. The guide groove 141 has an arc-shaped structure, and the length of the guide groove 141 is the rotation angle of the second groove 12 or the third groove 13.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, the two locking members 15 respectively include a first through hole 151 and a boss 152.

[0036] Two first through holes 151 are respectively opened on the first groove 11 and the second groove 12, and two bosses 152 are respectively set on the second groove 12 and the third groove 13.

[0037] In the above embodiments, the first groove 11, the second groove 12 and the third groove 13 are made of metal materials and have a certain deformation capability. When the second groove 12 rotates into the first groove 11 or the third groove 13 rotates into the interior of the second groove 12, the boss 152 can be engaged inside the first through hole 151 and emit a sharp sound. Relevant technicians can also judge whether the installation of this prefabricated building curtain wall structure is in place by the sound during the installation process.

[0038] In one embodiment of this utility model, such as Figure 3As shown, the length of the second groove 12 is less than that of the first groove 11, and the first groove 11 is provided with fastening bolts 41.

[0039] It is understandable that the length of the second groove 12 is less than that of the first groove 11 to avoid interference between the second groove 12 and the fastening bolt 41. The fastening bolt 41 can increase the strength of the first groove 11.

[0040] In addition, during subsequent maintenance, the elastic stress inside the first groove 11 becomes fatigued, and the elastic force of the first groove 11 is insufficient to ensure that the boss 152 is engaged inside the first through hole 151. At this time, the distance between the two sides of the first groove 11 can be adjusted by rotating the fastening bolt 41, so that the elastic stress inside the first groove 11 increases.

[0041] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, two second through holes 51 are symmetrically opened on the first groove 11.

[0042] Specifically, when connecting the first connecting component 1 to a preset position (e.g., a shear wall) of the main structure, relevant technicians can use the second through hole 51 to connect the first groove 11 to the main structure using expansion bolts.

[0043] In summary, the prefabricated building curtain wall structure of this utility model, by pivotally connecting the first groove, the second groove and the third groove together, can be stacked or extended, thereby providing sufficient working space around the building curtain wall during maintenance, thus facilitating subsequent maintenance.
