Description

Building curtain wall supporting structure

Technical Field

The utility model belongs to the technical field of building curtain walls, and particularly relates to a building curtain wall supporting structure.

Background

Curtain walls are facade systems typically made of glass, metal and other materials that are applied to the structural frame of a building to form a continuous transparent surface. Modern curtain walls generally adopt aluminum alloy or steel structures as supporting systems, and adapt to complex building forms through prefabricated components and on-site assembly modes.

Conventional curtain wall designs typically employ right angle corner structures to accommodate simple building shapes. However, as architectural design styles become diversified and complex, more and more buildings adopt designs with curves, sharp edges or irregular shapes, which present challenges to the corner structure of curtain walls. In order to accommodate different corner angles between curtain walls in different areas in a single project, the connecting frame of the curtain walls needs to have the function of angle adjustment.

The utility model with the application number 201820156753.5 discloses a buckling structure of a curtain wall corner upright post and a glass auxiliary frame, wherein a buckling ball socket and a buckling ball head are arranged between the auxiliary frame and a buckling piece, and the buckling ball head has a certain rotation angle in the buckling ball socket, so that the angle adaptation between curtain wall systems at two sides is realized. And most curtain wall corner designs are also used at present.

But this structure is in order to prevent that lock ball socket and lock bulb from breaking away from, and lock ball socket needs to possess certain wrap angle scope, again because the panel of lock ball socket has certain thickness, the panel that links to each other with it can produce the interference with the panel border of lock ball socket when lock bulb is rotatory, this rotation angle who has restricted lock ball socket greatly, and then leads to rotation angle between the curtain limited, is difficult to realize some comparatively extreme facade states.

Disclosure of utility model

The present utility model is directed to a building curtain wall supporting structure, which solves the above-mentioned problems of the prior art.

There is provided a building curtain wall support structure comprising:

Curtain wall upright posts;

the main frame body comprises two main flange plates and two auxiliary flange plates, the main frame body is connected with the curtain wall upright post, the two main flange plates are respectively formed by extending outwards from two sides of the main frame body, and the two auxiliary flange plates are respectively and correspondingly arranged with the two main flange plates;

The two auxiliary frames are respectively used for fixing two glass systems, two inner concave surfaces are respectively formed on the auxiliary frames, and the ends of the main flange plate and the auxiliary flange plate can be respectively contacted with the two inner concave surfaces and relatively rotate;

and the connecting piece is used for connecting the corresponding main flange plate and the corresponding aileron plate with each other.

The supporting structure provided by the embodiment of the utility model has the technical effects that the main flange plate and the auxiliary flange plate are used as the rotary hinges to rotate in the two inner concave surfaces, so that the influence caused by the interference of the auxiliary frame body can be reduced, the rotation angle between the main frame body and the auxiliary frame body can be increased, and meanwhile, the connection strength between the main frame body and the auxiliary frame body is not influenced. And because the angle between the two glass systems is formed by the combined action of the two auxiliary frames and the main frame, the effect of increasing the angle of one side is amplified to be twice.

Further, the auxiliary frame body comprises a bottom plate and a vertical plate, one inner concave surface is formed at the connection part of the bottom plate and the vertical plate, and the other inner concave surface is formed at one end of the vertical plate far away from the bottom plate.

The vertical plate is used for controlling the distance between the two inner concave surfaces, and as the main flange plate and the auxiliary flange plate have certain thickness, when the two inner concave surfaces are separated by a certain distance, the main flange plate and the auxiliary flange plate do not interfere when rotating to a certain limit angle.

Further, the ends of the main flange plate and the auxiliary flange plate respectively form a first sliding hinge and a second sliding hinge which extend reversely in the arc direction, and the first sliding hinge and the second sliding hinge are respectively contacted with the two inner concave surfaces.

The first sliding hinge is formed by outwards extending one side, close to the inner concave surface, of the main flange plate, and the second sliding hinge is formed by outwards extending one side, close to the inner concave surface, of the auxiliary flange plate, 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 cannot contact with the edge of the plate body of the auxiliary frame body prematurely, and a sufficient rotation angle is given to the main flange plate and the auxiliary flange plate.

Further, the two inner concave surfaces of the auxiliary frame body face to the same side relative to the vertical plate, and a rib plate is arranged on one side, away from the inner concave surfaces, of the vertical plate.

Because the vertical plate is formed by extending the original ball socket structure, when the length of the vertical plate is longer, the bending moment born by the connecting part of the vertical plate and the bottom plate is larger, and the structure bearing is unfavorable. Therefore, in order to improve the structural strength, the rib plates are utilized to increase the section moment of inertia of the connecting part of the vertical plate and the bottom plate, so that deformation caused by bending moment force is avoided.

Further, an included angle of alpha degrees is formed between the vertical plate and the bottom plate, and the alpha angle is 60-90 degrees.

Because the main flange plate and the auxiliary flange plate have a certain thickness, when the main flange plate and the auxiliary flange plate synchronously rotate to a certain limit angle, interference can be generated between the main flange plate and the auxiliary flange plate under the influence of the thickness. Therefore, the vertical plate and the bottom plate form a certain angle, so that the vertical plate and the bottom plate do not rotate in the same vertical plane, the thickness influence of the main flange plate and the auxiliary flange plate is eliminated, and the interference effect is reduced.

Further, the connecting piece comprises a cushion block and a fastener, wherein the cushion block is clamped between the main flange plate and the auxiliary flange plate, and the fastener is used for fixing the main flange plate, the cushion block and the auxiliary flange plate.

When the main flange plate and the auxiliary flange plate synchronously rotate, a certain distance is reserved between the main flange plate and the auxiliary flange plate, and the distance can be changed, so that a cushion block is required to be arranged between the main flange plate and the auxiliary flange plate to serve as a structural support and transmit acting force, and then the main flange plate, the auxiliary flange plate and the cushion block are fixed through fasteners.

Further, the fasteners are bolts and nuts, and the bolts sequentially penetrate through the main flange plate, the cushion block and the auxiliary flange plate and then are in threaded connection with the nuts.

After the main flange plate, the cushion block and the aileron flange plate are sequentially overlapped, positioning and punching are carried out among the main flange plate, the cushion block and the aileron flange plate, then bolts are penetrated and nuts are used for fixing, the connection mode is simpler, and the fastening degree is better.

Further, the fastener includes two splint, a plurality of bolt and a plurality of nut, the composite construction centre gripping after main flange board, cushion and aileron flange board are laminated in proper order is between two splint, a plurality of the bolt avoids composite construction and runs through two splint in proper order from composite construction's both sides back and corresponding nut threaded connection.

The connection mode does not need to punch and position the main flange plate, the cushion block and the auxiliary flange plate, simplifies the construction steps of punching and does not damage the structures of the main flange plate, the cushion block and the auxiliary flange plate.

Compared with the prior art, the utility model has the beneficial effects that:

The application divides the original single spherical hinge into two independent parts, namely the main flange plate and the auxiliary flange plate. The ends of the main flange plate and the auxiliary flange plate respectively rotate in the two inner concave surfaces, interference with the edge of the auxiliary frame body can be avoided in the rotating process, and the angle adjustment range between two side glass systems is enlarged. After the glass systems at two sides rotate to a specific angle, the main flange plate and the auxiliary flange plate are fixed through the connecting piece, and a limiting structure is formed between the two inner concave surfaces, so that the main frame body and the auxiliary frame body can be tightly fixed.

Referring to fig. 1, in the embodiment of the utility model, a building curtain wall supporting structure comprises a curtain wall upright 1, a main frame 2, two auxiliary frames 3 and a connecting piece 5, wherein the main frame 2 comprises two main flange plates 21 and two auxiliary flange plates 22, the main frame 2 is connected with the curtain wall upright 1, the two main flange plates 21 are respectively formed by extending outwards from two sides of the main frame 2, 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 for fixing two glass systems 4, two inner concave surfaces 31 are respectively formed on the auxiliary frames 3, the ends of the main flange plates 21 and the auxiliary flange plates 22 can be respectively contacted with the two inner concave surfaces 31 and relatively rotate, and the connecting piece 5 is used for connecting the corresponding main flange plates 21 and auxiliary flange plates 22 with each other.

The curtain wall upright 1 is a main supporting structure of a curtain wall system, the main frame body 2 is fixedly connected with the curtain wall upright 1 through fixing pieces such as bolts, and the glass system 4 sequentially transmits acting force to the curtain wall upright 1 through the auxiliary frame body 3 and the main frame body 2. It should be noted here that the support structure provided by the present application has the function of angular adjustment, represented in the illustrations given by the cross-section from a top view, and therefore would be mistakenly understood by the person skilled in the art that the curtain wall uprights 1 are only vertical column structures, the present application being applied only in the assembly relationship between the two glass systems 4 in the lateral direction. In practice, the curtain wall pillar 1 may also be a transverse beam structure, and the vertical assembly relationship between the two glass systems 4 shown in the cross-sectional view from the side view is not shown. In practice, the curtain wall upright 1 in the present application is only used as a frame supporting structure, the curtain wall upright 1 does not limit the assembly direction, and the curtain wall supporting structure in any direction is used, which is within the protection scope of the present application.

As a further example of a main embodiment, referring to fig. 1 and 2, the auxiliary frame 3 includes a bottom plate 32 and a vertical plate 33, and the bottom plate 32 may be connected to the glass system 4 by double-sided silica gel or other sealant. An inner concave surface 31 is formed at the connection portion of the bottom plate 32 and the vertical plate 33, and the inner concave surface 31 may be formed of an aluminum alloy profile, which enhances the structural strength of the bottom plate 32 on the basis of forming a specific shape. The other concave surface 31 is formed at an end of the vertical plate 33 remote from the bottom plate 32, and is curved to one side by the vertical plate 33 to form an arc plate. The two concave surfaces 31 have a specific wrap angle after being combined, and the wrap angle is determined by the connection strength of the main frame body 2 and the auxiliary frame body 3 and the required angle adjustment range. The function of the riser 33 is to provide a rotational space for the main flange plate 21 and the flap plate 22 and to reduce interference between the two due to the plate thickness.

Further, as shown in fig. 2 and 3, the two concave surfaces 31 of the auxiliary frame 3 face the same side with respect to the vertical plate 33, and a rib 321 is disposed on the side of the vertical plate 33 away from the concave surface 31. The rib plate 321 is integrally formed with the auxiliary frame body 3 by an aluminum alloy profile, so that the cross-sectional moment of inertia of the connection portion between the vertical plate 33 and the bottom plate 32 can be increased, and the structural strength thereof can be further enhanced. In order to ensure that the whole occupied space of the auxiliary frame body 3 is not enlarged, the position of the vertical plate 33 can move towards the joint part of the two glass systems 4 relative to the bottom plate 32, and a setting space is reserved for the rib plate 321.

Further, referring to fig. 1, 5 and 6, the standing plate 33 forms an angle with the bottom plate 32, and the angle is 60 ° to 90 °. The purpose of the angle is to eliminate interference effects due to the plate thickness between the main flange plate 21 and the flap plate 22. By moving the hinge support points of the main flange plate 21 and the auxiliary flange plate 22 from the same vertical plane to different vertical planes, the main flange plate 21 and the auxiliary flange plate 22 rotate to a certain limit angle, and then the plate structure is in a staggered state, so that the rotation angle between the auxiliary frame body 3 and the main frame body 2 is further enlarged.

As a further example of the main embodiment, referring to fig. 4, the ends of the main flange plate 21 and the flap plate 22 respectively form a first sliding hinge 211 and a second sliding hinge 221 extending in opposite directions in an arc shape, and the first sliding hinge 211 and the second sliding hinge 221 are respectively in contact with the two concave surfaces 31. The first sliding hinge 211 and the second sliding hinge 221 are shaped to fit the concave inner surface 31,

In one embodiment, first and second sliding hinges 211 and 221 are arcuate plate-like structures formed by extending the ends of main and aileron plates 21 and 22, respectively. The structure is characterized in that the part which does not participate in the matching sliding with the inner concave surface 31 in the structure is reduced as much as possible, and the whole weight of the supporting structure is reduced.

In one embodiment, first slide hinge 211 and second slide hinge 221 are each solid, cylindrical structures. The structure has the characteristics of simpler assembly process, higher structural strength, difficult deformation and high assembly precision.

As a further example of the main embodiment, referring to fig. 1, the connector 5 includes a spacer 51 and a fastener 52, where the spacer 51 is clamped between the main flange plate 21 and the flap plate 22, and the fastener 52 is used to fix the main flange plate 21, the spacer 51, and the flap plate 22. The spacer 51 may be made of a metal material or a plastic material, and mainly serves as a structural transition and a force transmitting function for filling gaps of different distances between the main flange plate 21 and the flap plate 22. During construction, the main flange plate 21 and the auxiliary flange plate 22 are positioned relative to the positions of the two inner concave surfaces 31, then a cushion block 51 with proper thickness is selected to be clamped between the main flange plate 21 and the auxiliary flange plate 22, and finally the auxiliary frame body 3 and the main frame body 2 can not rotate any more through fixing of the fastener 52.

In one embodiment, referring to fig. 7, the fastener 52 is a bolt and a nut, and the bolt penetrates the main flange plate 21, the cushion block 51 and the flap plate 22 in sequence and then is screwed with the nut. In this connection, it is necessary to perform the positioning of the main flange plate 21, the sub-flange plate 22, and the spacer 51, and then to perform the positioning and drilling separately, and then to assemble the bolts and nuts. The process is more complex but can save material for the fastener 52.

In one embodiment, referring to fig. 8, the fastener 52 includes two clamping plates, a plurality of bolts and a plurality of nuts, the composite structure formed by sequentially stacking the main flange plate 21, the cushion block 51 and the auxiliary flange plate 22 is clamped between the two clamping plates, and the plurality of bolts avoid the composite structure and sequentially penetrate through the two clamping plates from two sides of the composite structure and are in threaded connection with the corresponding nuts. The connection mode is achieved by simply assembling without drilling holes in the main flange plate 21, the cushion blocks 51 and the auxiliary flange plate 22, and the process is simple. However, this solution uses more material for the fastener 52 and is more costly to use than the simple bolt and nut solution.

The present application is not limited to the above embodiment. The above embodiments are merely examples, and embodiments having substantially the same configuration and the same effects as those of the technical idea within the scope of the present application are included in the technical scope of the present application. Further, various modifications that can be made to the embodiments and other modes of combining some of the constituent elements in the embodiments, which are conceivable to those skilled in the art, are also included in the scope of the present application within the scope not departing from the gist of the present application.
