Description

Technical Field

[0001] The utility model belongs to the technical field of building curtain walls, in particular to a building curtain wall supporting structure. Background Art

[0002] Curtain wall is an exterior facade system, usually made of glass, metal and other materials, covering the structural frame of the building to form a continuous and transparent surface. Modern curtain walls usually use aluminum alloy or steel structure as the support system, and adapt to complex building forms through prefabricated components and on-site assembly.

[0003] Traditional curtain wall design usually adopts right-angle corner structure to adapt to simple building forms. However, with the diversification and complexity of architectural design styles, more and more buildings adopt curved, angular or irregular shapes, which poses a challenge to the corner structure of curtain walls. In order to adapt to the different corner angles between curtain walls in different areas within a single project, the connection frame of the curtain wall needs to have the function of adjustable angle.

[0004] The utility model application number 201820156753.5 discloses a curtain wall corner column and glass frame buckling structure, which sets a buckling ball socket and a buckling ball head between the frame and the buckling piece, and the buckling ball head has a certain rotation angle in the buckling ball socket, thereby achieving angle adaptation between the curtain wall systems on both sides. Most of the current curtain wall corner designs also use this structure.

[0005] However, in order to prevent the snap-fit ​​ball socket and the snap-fit ​​ball head from detaching, the snap-fit ​​ball socket needs to have a certain wrap angle range. Also, since the plate of the snap-fit ​​ball socket has a certain thickness, the plate connected to it will interfere with the edge of the plate of the snap-fit ​​ball socket when the snap-fit ​​ball head rotates, which greatly limits the rotation angle of the snap-fit ​​ball head, thereby resulting in a limited rotation angle between curtain walls, making it difficult to achieve some more extreme facade states. Utility Model Content

[0006] The purpose of the utility model is to provide a building curtain wall supporting structure to solve the problems raised in the above-mentioned prior art.

[0007] Provided is a building curtain wall supporting structure, comprising:

[0008] Curtain wall columns;

[0009] A main frame, comprising two main flange plates and two secondary flange plates, the main frame being connected to the curtain wall columns, the two main flange plates being respectively extended outward from both sides of the main frame, and the two secondary flange plates being respectively arranged corresponding to the two main flange plates;

[0010] Two auxiliary frames, the two auxiliary frames are used to fix two glass systems respectively, two inner concave surfaces are formed on the auxiliary frames respectively, and the ends of the main flange plate and the auxiliary flange plate can contact with the two inner concave surfaces respectively and rotate relatively;

[0011] A connecting piece is used to connect the corresponding main flange plate and secondary flange plate to each other.

[0012] The supporting structure according to the embodiment of the utility model has at least the following technical effects: the main flange plate and the secondary flange plate are used as rotating hinges to rotate in two inner concave surfaces, which can reduce the influence of the interference of the auxiliary frame, so that the rotation angle between the main frame and the auxiliary frame can be increased, and the connection strength between the main frame and the auxiliary frame will not be affected. And because the angle between the two glass systems is formed by the two auxiliary frames and the main frame, the effect of increasing the angle on one side will be magnified to two times.

[0013] Furthermore, the auxiliary frame includes a bottom plate and a vertical plate, one of the inner concave surfaces is formed at a connection position between the bottom plate and the vertical plate, and the other inner concave surface is formed at an end of the vertical plate away from the bottom plate.

[0014] The vertical plate is used to control the distance between the two inner concave surfaces. Since the main flange plate and the secondary flange plate have a certain thickness, when the two inner concave surfaces are separated by a certain distance, the main flange plate and the secondary flange plate will not interfere with each other until they are rotated to some extreme angles.

[0015] Furthermore, the ends of the main flange plate and the secondary flange plate respectively form a first sliding hinge and a second sliding hinge extending in opposite arc directions, and the first sliding hinge and the second sliding hinge are in contact with two inner concave surfaces respectively.

[0016] The first sliding hinge is formed by extending outward from the side of the main flange plate close to the inner concave surface, and the second sliding hinge is formed by extending outward from the side of the auxiliary flange plate close to the inner concave surface, so that when the first sliding hinge and the second sliding hinge rotate in the two inner concave surfaces respectively, the main flange plate and the auxiliary flange plate will not contact the edge of the plate body of the auxiliary frame too early, giving the main flange plate and the auxiliary flange plate a sufficient rotation angle.

[0017] Furthermore, the two inner concave surfaces of the auxiliary frame body face the same side relative to the vertical plate, and a rib plate is provided on a side of the vertical plate away from the inner concave surfaces.

[0018] Since the vertical plate is formed by extending the original ball-and-socket structure, the longer the vertical plate is, the greater the bending moment at the connection between the vertical plate and the bottom plate is, which is not conducive to the structural load. Therefore, in order to improve the structural strength, the rib plate is used to increase the section inertia moment at the connection between the vertical plate and the bottom plate to ensure that this place will not be deformed due to the bending moment.

[0019] Furthermore, an angle of α is formed between the vertical plate and the bottom plate, and the angle α is 60° to 90°.

[0020] Since the main flange plate and the secondary flange plate have a certain thickness, when the two rotate synchronously to some extreme angles, interference will occur between the two due to the influence of thickness. Therefore, by making the vertical plate and the bottom plate form a certain angle, the two are not rotated in the same vertical plane, thereby eliminating the thickness influence of the main flange plate and the secondary flange plate and reducing the interference effect.

[0021] Furthermore, the connecting member includes a pad and a fastener, wherein the pad is clamped between the main flange plate and the secondary flange plate, and the fastener is used to fix the main flange plate, the pad and the secondary flange plate.

[0022] When the main flange plate and the secondary flange plate rotate synchronously, there is a certain distance between them and this distance will change. Therefore, it is necessary to set a pad between the main flange plate and the secondary flange plate as a structural support and to transmit the force, and then fix the main flange plate, the secondary flange plate and the pad by fasteners.

[0023] Furthermore, the fasteners are bolts and nuts, and the bolts sequentially penetrate the main flange plate, the pad and the secondary flange plate and are threadedly connected with the nuts.

[0024] When the main flange plate, the pad and the secondary flange plate are stacked in sequence, positioning holes are punched between the three, and then bolts are passed through and fixed with nuts. The connection method is relatively simple and the fastening degree is better.

[0025] Furthermore, the fastener includes two clamping plates, a plurality of bolts and a plurality of nuts. The composite structure in which the main flange plate, the gasket and the secondary flange plate are stacked in sequence is clamped between the two clamping plates. The plurality of bolts avoid the composite structure and penetrate the two clamping plates in sequence from both sides of the composite structure and are then threadedly connected with the corresponding nuts.

[0026] This connection method does not require drilling and positioning of the main flange plate, the pad and the secondary flange plate, which simplifies the drilling construction steps and does not damage the structures of the three.

[0027] Compared with the prior art, the beneficial effects of the utility model are:

[0028] The present application divides the original single ball joint into two independent parts, namely the main flange plate and the secondary flange plate. The ends of the main flange plate and the secondary flange plate rotate in two inner concave surfaces respectively, and can avoid interference with the edges of the attached frame during the rotation process, thereby increasing the angle adjustment range between the glass systems on both sides. After the glass systems on both sides rotate to a specific angle, the main flange plate and the secondary flange plate are fixed by connecting parts, and a limiting structure is formed between the two inner concave surfaces, so that the main frame and the attached frame can be tightly fixed.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0040] Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can also be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed in this application, some changes in design, manufacturing or production based on the technical content disclosed in this application are just conventional technical means, and should not be understood as insufficient content disclosed in this application.

[0041] However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters and repeated descriptions of substantially the same structures may be omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter described in the claims.

[0042] See also Figure 1 As shown, in an embodiment of the utility model, a building curtain wall support structure includes a curtain wall column 1, a main frame 2, two auxiliary frames 3 and a connector 5; the main frame 2 includes two main flange plates 21 and two auxiliary flange plates 22, the main frame 2 is connected to the curtain wall column 1, the two main flange plates 21 are respectively extended outward from both sides of the main frame 2, and the two auxiliary flange plates 22 are respectively arranged corresponding to the two main flange plates 21; the two auxiliary frames 3 are respectively used to fix two glass systems 4, two inner concave surfaces 31 are respectively formed on the auxiliary frames 3, and the ends of the main flange plates 21 and the auxiliary flange plates 22 can respectively contact with the two inner concave surfaces 31 and rotate relatively; the connector 5 is used to connect the corresponding main flange plates 21 and the auxiliary flange plates 22 to each other.

[0043] The curtain wall column 1 is the main supporting structure of the curtain wall system. The main frame 2 is fixedly connected to the curtain wall column 1 by bolts and other fixings. The glass system 4 sequentially transmits the force to the curtain wall column 1 through the auxiliary frame 3 and the main frame 2. It should be noted here that the support structure provided by the present application has the function of angle adjustment. In the given figure, it is presented through a cross-sectional view from a top-down perspective. Therefore, it will cause those skilled in the art to mistakenly understand that the curtain wall column 1 is only a vertical column structure, and the present application is only applied to the assembly relationship between the two glass systems 4 in the horizontal direction. In fact, the curtain wall column 1 can also be a horizontal beam structure at the same time. The figure does not show the vertical assembly relationship between the two glass systems 4 presented by the cross-sectional view from a side view. In fact, the curtain wall column 1 in the present application is only used as a frame support structure. The curtain wall column 1 does not limit the assembly direction. The curtain wall support structure of the present application is used in any direction and should be within the scope of protection of the present application.

[0044] As a further example of the main implementation, see Figure 1 and Figure 2 As shown, the auxiliary frame 3 includes a bottom plate 32 and a vertical plate 33, and the bottom plate 32 can be connected to the glass system 4 through double-sided silicone or other sealants. An inner concave surface 31 is formed at the connection between the bottom plate 32 and the vertical plate 33, and the inner concave surface 31 can be formed by an aluminum alloy profile, and the structural strength of the bottom plate 32 is enhanced on the basis of forming a specific shape. Another inner concave surface 31 is formed at one end of the vertical plate 33 away from the bottom plate 32, and the vertical plate 33 is bent to one side to form an arc plate. The two inner concave surfaces 31 have a specific wrap angle after being combined, and the wrap angle is determined by the connection strength between the main frame 2 and the auxiliary frame 3 and the required angle adjustment range. The function of the vertical plate 33 is to provide a rotation space for the main flange plate 21 and the secondary flange plate 22 and reduce the interference between the two due to the plate thickness.

[0045] For further information, see Figure 2 and Figure 3 As shown, the two inner concave surfaces 31 of the auxiliary frame 3 face the same side relative to the vertical plate 33, and a rib plate 321 is provided on the side of the vertical plate 33 away from the inner concave surface 31. The rib plate 321 is formed integrally with the auxiliary frame 3 through an aluminum alloy profile, which can increase the sectional inertia moment of the connection part between the vertical plate 33 and the bottom plate 32, thereby enhancing the structural strength there. In order to ensure that the overall occupied space of the auxiliary frame 3 is not expanded, the position of the vertical plate 33 can be moved relative to the bottom plate 32 toward the joint part of the two glass systems 4, and a space is reserved for the rib plate 321.

[0046] For further information, see Figure 1 , Figure 5 and Figure 6 As shown, a certain angle is formed between the vertical plate 33 and the bottom plate 32, and the angle is 60° to 90°. The purpose of forming the angle is to eliminate the interference caused by the thickness between the main flange plate 21 and the secondary flange plate 22. By moving the hinge points of the main flange plate 21 and the secondary flange plate 22 from the same vertical plane to different vertical planes, the plate structures are in a staggered state after the main flange plate 21 and the secondary flange plate 22 are rotated to some extreme angles, further expanding the rotation angle between the auxiliary frame 3 and the main frame 2.

[0047] As a further example of the main implementation, see Figure 4 As shown, the ends of the main flange plate 21 and the secondary flange plate 22 respectively form a first sliding hinge 211 and a second sliding hinge 221 extending in opposite arc directions, and the first sliding hinge 211 and the second sliding hinge 221 are respectively in contact with the two inner concave surfaces 31. The shapes of the first sliding hinge 211 and the second sliding hinge 221 are adapted to the inner concave surfaces 31.

[0048] In one embodiment, the first sliding hinge 211 and the second sliding hinge 221 are arc-shaped plate structures respectively extended from the ends of the main flange plate 21 and the secondary flange plate 22. The characteristic of this structure is to minimize the parts of the structure that do not participate in the sliding cooperation with the inner concave surface 31, thereby reducing the overall weight of the supporting structure.

[0049] In one embodiment, the first sliding hinge 211 and the second sliding hinge 221 are respectively solid columnar structures. The characteristics of this structure are that the assembly process is relatively simple, the structural strength is high, it is not easy to deform, and the assembly precision is high.

[0050] As a further example of the main implementation, see Figure 1 As shown, the connector 5 includes a pad 51 and a fastener 52. The pad 51 is clamped between the main flange plate 21 and the secondary flange plate 22. The fastener 52 is used to fix the main flange plate 21, the pad 51 and the secondary flange plate 22. The pad 51 can be made of metal material or plastic material, and mainly plays the role of structural transition and force transmission, and is used to fill the gaps of different distances between the main flange plate 21 and the secondary flange plate 22. During construction, the main flange plate 21 and the secondary flange plate 22 are first positioned relative to the positions of the two inner concave surfaces 31, and then a pad 51 of appropriate thickness is selected and clamped between the main flange plate 21 and the secondary flange plate 22, and finally fixed by the fastener 52 so that the auxiliary frame 3 and the main frame 2 can no longer rotate.

[0051] In one embodiment, see Figure 7 As shown, the fastener 52 is a bolt and a nut, and the bolt passes through the main flange plate 21, the pad 51 and the secondary flange plate 22 in sequence and is threadedly connected with the nut. This connection method requires that the main flange plate 21, the secondary flange plate 22 and the pad 51 are positioned and positioned separately, and then the bolt and the nut are assembled. The process is relatively complicated, but it can save the material of the fastener 52.

[0052] In one embodiment, see Figure 8 As shown, the fastener 52 includes two clamping plates, a number of bolts and a number of nuts. The composite structure after the main flange plate 21, the pad 51 and the secondary flange plate 22 are stacked in sequence is clamped between the two clamping plates. A number of bolts avoid the composite structure and pass through the two clamping plates in sequence from both sides of the composite structure and are threadedly connected with the corresponding nuts. This connection method does not require drilling holes on the main flange plate 21, the pad 51 and the secondary flange plate 22. Only simple assembly is required, and the process is relatively simple. However, the fastener 52 used in this solution has more materials, and the cost of use is higher than that of a simple bolt and nut solution.

[0053] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
