Description

Technical Field

[0001] The invention relates to a curtain wall supporting system. Background Art

[0002] At present, as architectural shapes become more and more diverse, the facades of buildings are becoming more and more complex. In particular, in order to meet the requirements of function and appearance, architects are increasingly using curved surfaces with various shapes as the facades of buildings. In particular, the use of two-way curved curtain walls in various buildings (especially entertainment buildings) is becoming more and more frequent. Considering the complexity of the curved surface and the difficulty of design and construction, designers usually use a large number of flat panels to fit the curved curtain wall.

[0003] On the other hand, the planar panels are not directly connected to the main structure of the building, but are connected to the main structure of the building through the curtain wall support system. For example, the planar panels are connected to the aluminum alloy frame, the aluminum alloy frame connected with the planar panels is connected to the steel keel structure, and then the steel keel structure is connected to the main structure of the building.

[0004] Generally speaking, considering factors such as construction costs, aluminum alloy frames are usually flat frames. However, in order to meet the requirements of curved surface modeling, adjacent keel components (usually rod-shaped components) in steel keel structures are sometimes not coplanar but skewed. As a result, since the adjacent keel components are in a skewed state and the aluminum alloy frame connected to them is a flat frame, the on-site installation between the two is difficult, and there are even cases where the installation cannot be performed. Summary of the invention

[0005] Technical problem to be solved by the invention

[0006] The present invention is formed in view of the above situation, and its purpose is to provide a curtain wall support system that can achieve the positioning and installation of planar panels and the fitting of curved surface shapes while ensuring the on-site connection and installation between the planar frame and the keel components.

[0007] Technical solutions adopted to solve technical problems

[0008] The first technical solution of the present invention provides a curtain wall support system for supporting a curtain wall with a curved surface shape, wherein the curtain wall with a curved surface shape is composed of a plurality of planar panels, and the curtain wall support system is characterized in that it includes:

[0009] A planar frame, the planar frame connecting and supporting one of the planar panels or a plurality of adjacent planar panels;

[0010] a first keel member, the first keel member being arranged on the main structure in a manner extending along a first direction, that is, an extending direction of a first main slit of the curtain wall, the first main slit being a slit sandwiched between adjacent planar panels and extending within a range of at least two planar panels adjacent to each other along the first direction; and

[0011] A second keel member, the second keel member is provided for installation of the planar frame, is arranged at intervals along the first direction and is connected between adjacent first keel members, so that a local installation plane is formed between adjacent second keel members, and an angle between the local installation plane and the plane where the planar frame for installation is located is less than a preset angle threshold.

[0012] According to the curtain wall supporting system described in the first technical solution, by connecting the first keel member and the second keel member in a manner that the angle between the local installation plane surrounded by them and the plane where the planar frame as the installation object is located is less than a preset value, the planar frame can be installed with the first keel member and the second keel member in a manner that is basically parallel to the local installation plane, thereby ensuring on-site installation of the planar frame and the keel structure, and the installation is relatively easy.

[0013] Based on the first technical solution, in the second technical solution of the present invention, it further includes a first keel connecting member, which connects the first keel member to the main structure. The first keel connecting member is connected between the first keel member and the main structure in a plane passing through the first keel member and orthogonal to the main structure.

[0014] According to the curtain wall support system described in the second technical solution, the force transmitted through the first keel member can be made more reasonable. Specifically, if the first keel connecting member is connected between the first keel member and the main structure in a manner that is not located in a plane orthogonal to the main structure but oblique to the main structure, then, under the action of the load of the planar plate, the first keel connecting member is prone to generate out-of-plane forces, and the out-of-plane forces have an adverse effect on the stability of the planar frame, which will cause unreasonable forces on the planar frame. To this end, by connecting the first keel connecting member between the first keel member and the main structure in a manner that is located in a plane orthogonal to the main structure, the plane where the first keel member and the first keel connecting member are located can be perpendicular to the main structure, thereby being able to avoid as much as possible the generation of undesirable out-of-plane forces under the load of the planar plate.

[0015] Based on the first or second technical solution, in the third technical solution of the present invention, a corbel component is further included, wherein the corbel component is arranged at a portion of the first keel component away from or close to a side of the main structure. The second keel component is connected between adjacent first keel components via the corbel component.

[0016] According to the curtain wall support system described in the third technical solution, it is possible to ensure that the second keel member and the first keel member enclose a local installation plane. Specifically, sometimes, two adjacent first keel members are not only non-parallel, but the angle between the two (which can be understood as the angle between non-coplanar straight lines) may be large. In such a case, if the second keel member is directly installed to the first keel member, it may be impossible to find a plane due to the excessive angle between the two adjacent first keel members for the installation of the second keel member. To this end, according to the curtain wall support system described in the present technical solution, by adding an outwardly projecting corbel member to the first keel member and connecting the second keel member to the first keel member via the corbel member, it is possible to avoid the problem of being unable to find a suitable local installation plane due to the excessive angle between the first keel members.

[0017] Based on the first technical solution, in the fourth technical solution of the present invention, the end of one planar frame located on the upper side in the first direction and the top of the other planar frame located on the lower side of two adjacent planar frames in the first direction are commonly connected to a second keel member.

[0018] According to the curtain wall support system described in the fourth technical solution, two adjacent planar frames in the first direction can be connected by only one second keel component, thereby saving the amount of keel structure.

[0019] Based on the first technical solution, in the fifth technical solution of the present invention, the end of one planar frame located on the upper side in the first direction and the top of the other planar frame located on the lower side of two adjacent planar frames in the first direction are respectively connected to a second keel member.

[0020] According to the curtain wall support system described in the fifth technical solution, compared with connecting two adjacent planar frames in the first direction only through one second keel member, the structure of the connector for connecting the planar panel and the second keel member can be simplified. On the other hand, since the angle between adjacent first keel members varies greatly, if only one second keel member is used for connection, it may not be possible to ensure that two adjacent local installation planes in the first direction are formed at the same time. Taking this into account, according to the curtain wall support system described in this technical solution, by connecting each second keel member to only one planar frame, it is possible to flexibly set a local installation plane for installing each planar frame, thereby improving the feasibility of construction and installation.

[0021] Based on the first technical solution, in a sixth technical solution of the present invention, the curtain wall support system further comprises: a frame side connecting member, the frame side connecting member is used to be connected to the planar frame; and a panel side connecting member, the panel side connecting member is used to be connected to the planar panel. The panel connecting member is connected to the frame connecting portion in a manner that allows relative movement.

[0022] According to the curtain wall support system described in the sixth technical solution, by setting a kinematic connection method, it is helpful to connect and install the planar panel and the planar frame. Specifically, considering factors such as installation errors during the construction process, if a certain redundancy is not reserved in the connection structure between the planar panel and the planar frame, the two may not be connected normally, and even the connection structure may be damaged. To this end, according to the curtain wall support system described in this technical solution, by connecting the frame-side connecting member connected to the planar frame and the panel-side connecting member connected to the planar panel in a manner that allows relative movement, it is possible to provide a certain adjustment space for the connection and installation, thereby facilitating the connection and installation of the two.

[0023] Based on the first or third technical solution, in a seventh technical solution of the present invention, the planar frame connects and supports the planar panels located on both sides of the first main gap. Furthermore, the planar frame includes a first connecting member for connecting the planar panels located on one side of the first main gap and a second connecting member for connecting the planar panels located on the other side of the first main gap.

[0024] According to the curtain wall support system described in the seventh technical solution, it is possible to avoid the problems of difficult installation and construction caused by only setting up one first connecting member. Specifically, when only one first connecting member is set up to connect the planar panels located on both sides of the first main gap, if the planar panels located on both sides of the first main gap are connected to the same first connecting member by means of through bolts, it may cause the through bolts used to connect the planar panels located on one side of the first main gap and the through bolts used to connect the planar panels located on the other side to conflict with each other at the installation position on the first connecting member, thereby causing a situation in which the installation cannot be performed. To this end, according to the curtain wall support system described in this technical solution, by separately setting up a first connecting member for installing the planar panels located on one side and a second connecting member for installing the planar panels located on the other side, it is possible to avoid the above-mentioned situation in which the installation cannot be performed.

[0038] Below, refer to Figures 1 to 13 , the specific structure of the curtain wall support system of one embodiment of the present application is described.

[0039] Figure 1 FIG. 1 is a partial three-dimensional schematic diagram of the main structure M of a building to which a curtain wall support system S according to an embodiment of the present application is applied. Figure 1 As shown, in this embodiment, the main structure M of the building for installing the curtain wall support system S is a steel frame structure, including a plurality of steel beams M1 and a plurality of steel columns M2. The steel beam M1 is a horizontal structural load-bearing member, which receives the load transferred from the floor slab (not shown) laid above it, and transfers these loads to the steel column M2. The steel column M2 is a vertical structural load-bearing member, which receives the load transferred from the steel beam M1 and the load directly transferred from the floor slab, and transfers these loads to the foundation structure at the bottom (not shown). In addition, Figure 1 It can be observed that the steel beam M1 of the main structure 1 is pre-installed with an upper wall connector M3, which is used for connecting the keel components of the keel structure C described later, namely the first keel component C1 and the second keel component C2, so as to connect the keel structure C with the main structure M. It should be noted that the steel frame structure mentioned here is only an example of the main structure M and is not limited thereto. That is, according to the actual needs of the architectural design and structural design, any reinforced concrete structure, steel structure or other material as the load-bearing structure such as reinforced concrete frame structure, frame-shear wall structure, frame-core tube structure, space grid structure can be adopted.

[0040] Figure 2 A perspective view of a curtain wall structure A installed on the peripheral structure of a main structure M is shown. Figure 3 The main structure M is shown. Figure 1The partial perspective view of the curtain wall structure A shown in FIG. Figure 2 and Figure 3 It can be observed that in order to meet the architect's requirements for the exterior facade of the building, in this embodiment, the curtain wall structure as a component of the exterior facade is formed into a two-way curved surface. However, considering the construction feasibility and difficulty of the two-way curved surface, as in this embodiment, architects usually consider using a large number of small planar panels to splice and fit the curtain wall structure that constitutes the two-way curved surface through slight angle changes, size changes or shape changes between the planar panels. In particular, in order to meet specific visual requirements, concrete panels that pursue natural pure colors and durable and stable visual perception are often used as curtain wall panels. For example, UHPC concrete is used as the material of the curtain wall panels in this embodiment. However, according to different design requirements for the building, materials such as marble, granite, and glass can also be used to make curtain wall panels.

[0041] On the other hand, in order to meet the requirements of the building facade, various gaps of different forms are formed between adjacent curtain wall panels by splicing the curtain wall panels in accordance with certain design requirements in the curtain wall structure A. For example, in this embodiment, Figure 2 and Figure 3 As shown, the curtain wall panel A is formed with a first main slit S1 extending in a zigzag shape in a first direction (i.e., the vertical direction of the building) and a second secondary slit S2 extending in a zigzag shape in a second direction (i.e., the horizontal direction of the building) which is approximately orthogonal to the first direction. Although both extend in a zigzag shape, there are differences between the two. Specifically, when the spatial curved surface formed by the curtain wall structure A is projected onto a vertical plane, the projection of the first main slit S1 is formed to extend in a substantially straight line, while the projection of the second secondary slit S2 is formed to extend in a zigzag shape. In addition, in the present embodiment, the first main slit S1 is formed in a manner extending throughout the entire curtain wall structure A in the first direction, but this is only an example, and it can also be formed in a manner extending in the first direction and in a local range of the curtain wall structure A. In addition, in the present embodiment, the first direction is the vertical direction of the building as an example for explanation, but it is not limited to this, and it can also be other directions. In addition, in the present embodiment, the extension range and geometric shape of the second secondary slit S2 can also be changed according to specific design requirements, and the second direction can also be a direction other than the horizontal direction of the building. Furthermore, the curtain wall structure A is not limited to the first main gap S1 and the second secondary gap S2, and may include other types of gaps. Figure 2 and Figure 3 The gap formed in the curtain wall structure A shown is used as an example for explanation.

[0042] Figure 41 is a perspective view showing an example of a planar panel 1 which is a curtain wall panel constituting the curtain wall structure A. As an example of the planar panel 1 in this embodiment, Figure 4 A quadrilateral-shaped planar plate 1 is shown, but the planar plate 1 is not limited thereto, and the planar plate 1 may have any other shape. Figure 4 As shown, the planar plate 1 includes a planar plate portion 11 and a folded edge portion 12 formed on the periphery of the planar plate portion 11 and protruding toward the main structure M. The surface of the side of the planar plate portion 11 that is not provided with the folded edge portion 12 faces the outdoor space of the building when installed on the main structure M, thereby providing the desired visual experience. In addition, considering the overall strength of the plate and the visual effect of the facade, the folded edge portion 12 protruding from the surface of the portion toward the main structure M is provided on the entire periphery of the portion of the planar plate portion 11 on the side of the main structure M. Generally speaking, during the installation process of the planar plate, adjacent planar plates 1 are prone to collision. Since the planar plate portion 11 is only a flat plate with a relatively thin thickness, if the planar plates 1 collide with each other, the edge of the planar plate 1 is prone to damage, so that the requirements for curved surface modeling cannot be met. To this end, by providing a folding portion 12 protruding from the surface of the flat plate portion 11 on the entire periphery of the flat plate portion 11, the edge portion of the flat plate portion 11 can be thickened, thereby improving the impact resistance of the edge portion of the flat plate portion 11, thereby avoiding damage to the edge portion. In addition, considering the visual effect of the building's appearance, the folding portion 12 protrudes from the surface of the flat plate portion 11 to the inner side, that is, the main structure M side. In addition, in some buildings, in order to meet the lighting effect at night, a light-emitting lamp will be set between the main structure M and the curtain wall system A. By providing the folding portion 12, the side light that is not expected to be exposed can be blocked, thereby forming the desired night lighting display effect. However, it should be noted that, according to the actual design and installation conditions, the folding portion 12 may not be provided.

[0043] On the other hand, in order to connect the planar panel 1 to the planar panel 2 described later, a sleeve portion 13 for connecting to a panel connecting member 4 described later for connecting the planar panel 1 to the planar frame 2 described later is formed on the surface of the planar panel 1 close to the main structure M. Figure 4As shown, the sleeve portion 13 is formed by protruding from the surface of the plane plate portion 11 of the plane plate 1 close to the main structure M side, and a connection hole is formed in the protruding portion, through which the plate side connection member 41 described later is connected. There are many ways of connection, such as threaded connection, welding connection, etc. The reason why the sleeve portion 13 is formed in a protruding manner is to make the connection hole have a sufficient depth to ensure that the plate side connection member 41 and the sleeve portion 13 have sufficient connection strength. In addition, considering the configuration and installation of the vertical connection members and the horizontal connection members located on both sides of the planar frame 2 described later and the vertical keel member (i.e., the first keel member) 31 and the horizontal keel member (i.e., the second keel member) 32 of the keel structure 3 described later, it is preferred that each sleeve portion 13 is formed in a manner that the respective protruding edges are separated from the edge of the planar plate 1 by a specified distance. In this way, it is possible to avoid the situation where the planar frame 2 and / or the keel structure 3 are difficult or even impossible to install.

[0044] Figure 5 FIG. 2 shows a schematic diagram of a planar frame system D connected to and supporting a curtain wall structure A. Figure 5 As shown, the planar frame system D comprises a plurality of planar frames 2 and a plurality of panel connecting members 4 for connecting the planar frames 2 to the planar panels 1. Figure 5 As shown, the planar frame 2 is a rectangular planar frame, which connects and supports a plurality of planar panels 1 located on both sides of the first main gap S1, and includes a pair of side vertical connecting members (also called side vertical rod-shaped members) 21 located on both sides in the horizontal direction (i.e., the second direction), a pair of side horizontal connecting members (also called side horizontal rod-shaped members) 22 located on both sides in the vertical direction (i.e., the first direction), and a pair of intermediate vertical connecting members (also called intermediate vertical rod-shaped members) located between the pair of side vertical connecting members 21 in the horizontal direction, wherein the pair of intermediate vertical connecting members includes a first intermediate vertical connecting member (i.e., the first connecting member) 23 and a second intermediate vertical connecting member (i.e., the second connecting member) 24. In addition, in the present embodiment, the planar frame 2 is a frame made of aluminum alloy.

[0045] Figure 6 FIG. 1 shows a schematic diagram of a planar frame system D connected to a curtain wall structure A. Figure 6 As shown, the first middle vertical connecting member 23 is connected to and supports a plurality of planar panels 1 located on one side (left side in the figure) of the first main gap S1, while the second middle vertical connecting member 24 is connected to and supports a plurality of planar panels 1 located on the other side (right side in the figure) of the first main gap S1. Figure 6It can be observed that the size of each planar frame 2 can be different, so that the number of connected planar panels can also be different.

[0046] Figure 7 A perspective view of a connecting structure 4 connecting a planar frame 2 to a planar panel 1 is shown. Figure 8 FIG. 4 shows a top view of a connecting structure 4 connecting a planar frame 2 to a planar panel 1. Figure 7 and Figure 8 As shown, the connection structure 4 mainly includes a panel side connection member 41 and a frame side connection member 42. In the present embodiment, angle steel is used as an example of the panel side connection member 41 and the frame side connection member 42. Considering that the planar frame 2 is made of aluminum alloy, the frame side connection member 42 is connected to the planar frame 2 by bolt connection. In addition, one end of the panel side connection member 41 is connected to the frame side connection member 42 by, for example, bolt connection, welding connection, etc., and the other end is connected to the planar panel 1 by a connection member inserted and fixed in the connection hole of the sleeve part 13. In particular, a straight long hole or a cross-shaped long hole is formed in either the panel side connection member 41 or the frame side connection member 42. In this way, during the installation process, the panel side connection member 41 and the frame side connection member 42 are connected in a manner that allows relative movement. In the case where the long hole is set as a unidirectional straight long hole extending in one direction, the plate side connecting member 41 and the frame side connecting member 42 can be connected to each other in a relatively movable manner in the one direction, and in the case where the long hole is set as a cross-shaped long hole extending in both one direction and another direction, the plate side connecting member 41 and the frame side connecting member 42 can be connected to each other in a relatively movable manner in the above-mentioned one direction and another direction. Generally, due to factors such as manufacturing errors, manual or mechanical construction errors, if a certain installation margin is not reserved in advance between the plate side connecting member 41 and the frame side connecting member 42, it may cause the plate side connecting member 41 and the frame side connecting member 42 to be difficult to install, and may even cause the situation that the installation cannot occur. For this reason, by setting a unidirectional straight long hole or a cross-shaped long hole, during the installation process, the plate side connecting member 41 and the frame side connecting member 42 can be connected to each other in a relatively movable manner, so that the connection between the two can be adjusted corresponding to errors such as manufacturing errors or construction errors, thereby achieving the connection and installation of the two.

[0047] Fig. 9The schematic diagram shows the installation problem of the planar panels 1 located on both sides of the first main gap when only one intermediate vertical connecting member is provided. As mentioned above, considering that the planar frame 2 is made of aluminum alloy, the frame side connecting member 42 is connected to the planar frame 2 by bolt connection. In this case, if the planar frame 2 is provided with only one intermediate vertical connecting member between a pair of side vertical connecting members 21 to connect the planar panels 1 located on both sides of the first main gap S1, then, due to the use of bolted through connection, as shown in FIG. Fig. 9 As shown in the figure, the two planar panels 1 located on both sides of the first main gap S1 and at the same height cannot be connected to the middle vertical connecting member at the same time. Therefore, in the present embodiment, a pair of middle vertical connecting members, namely, a first middle vertical connecting member (i.e., first connecting member) 23 and a second middle vertical connecting member (i.e., second connecting member) 24, are arranged between a pair of side vertical connecting members 21 of the planar frame 2. In this way, the above-mentioned installation problem can be avoided.

[0048] Fig.10 A schematic diagram showing a keel structure C of the curtain wall support system S of this embodiment connected to the main structure M is shown. Fig.11 The schematic diagram of the keel structure C connected to the planar panels 1 and the main structure M through the planar frame system D is shown. Fig.10 As shown, the keel structure C is made of steel, for example, and mainly includes a first keel member C1, a second keel member C2, a first keel connecting member C3, and a frame-keel connecting member C4. Figure 2 The keel structure C corresponding to the curtain wall structure A shown in the figure has a first keel component C1 which is a vertical keel component and a second keel component C2 which is a horizontal keel component. The first keel component C1 is connected to the main structure M (pre-installed) by the first keel connecting component C3. Fig.10 The upper wall connector M3 on the steel beam M1 is connected to connect the keel structure C to the main structure M. In addition, the first keel member C1 is arranged to extend along the extension direction of the first main gap S1, that is, the first direction. The second keel member C2 is connected between two adjacent first keel members C1, and the planar frame 2 is connected by a plurality of frame-keel connecting members C4 installed on the second keel member C2. Fig.11As shown, two second keel members C2 are respectively provided for each planar frame 2 or each plurality of planar frames 2 located at the same height for connection. More specifically, two second keel members C2 are respectively provided for each planar frame 2 or each plurality of planar frames 2 located at the same height, wherein one second keel member C2 is connected to the side transverse connecting member located on the upper side of a pair of side transverse connecting members 22 of the planar frame 2, and the other second keel member C2 is connected to the side transverse connecting member located on the lower side of a pair of side transverse connecting members 22 of the planar frame 2. The reason for providing the second keel members C2 in this way will be described below. Prior to this, the configuration and connection method of the second keel members C2 for connecting each planar frame 2 or each plurality of planar frames 2 located at the same height will be described first.

[0049] from Fig.10 and Fig.11 It can be observed that since the first keel member C1 is arranged in a manner extending along the extension direction of the first main gap S1, that is, the first direction, a row of first keel members C1 corresponding to each first main gap S1 presents a spatial broken line shape. However, since the extension directions of adjacent first main gaps S1 are not exactly the same due to the requirements of curved surface modeling, the straight lines where two adjacent first keel members C1 located in the same range in the first direction are located may form skew lines. On the other hand, considering that the frame connected to the keel structure C is a planar frame 2, the keel structure C needs to be arranged in a form that can be installed for each planar frame 2. More specifically, an installation plane that can be installed for the planar frame 2 needs to be formed by the first keel member C1 and the second keel member C2. Here, the installation plane formed by adjacent first keel members and the second keel member connected therebetween is referred to as a local installation plane. Therefore, the second keel member C2 cannot be connected to the first keel member C1 at will, but is connected between two adjacent first keel members C1 in a manner that two adjacent second keel members C2 connected between two adjacent first keel members C1 and for installation of one or more planar frames 2 are enclosed with a part of the first keel member C1 located between the two second keel members C2 to form a local installation plane, and the angle between the local installation plane and the plane where the planar frame 2 for installation is located is less than a preset angle threshold, preferably, the local installation plane is parallel to the plane where the planar frame 2 for installation is located. As for the specific value of the angle threshold, it can be set arbitrarily as long as the installation of the planar frame 2 can be ensured.

[0050] Fig.12A schematic diagram of a keel structure C in which a corbel member E is arranged on the first keel member C1 is shown. Sometimes, due to the large spatial angle between a pair of non-coplanar straight lines formed by a straight line where one adjacent first keel member C1 is located and a straight line where another first keel member C1 is located, it may be impossible to find a suitable installation point on the first keel member C1, so that the second keel member C2 is connected to the first keel member C1 in a manner that can form a local installation plane together with the first keel member C1. To this end, as a solution, a corbel member E protruding from the first keel member C1 is added to the first keel member C1. Therefore, by arranging the corbel member E on one or both of the two adjacent first keel members C1 and connecting one end and both ends of the second keel member C2 to the first keel member C1 through the corbel member E, it is possible to avoid the situation in which the local installation plane cannot be formed due to the large spatial angle between the two adjacent first keel members C1.

[0051] As described above, two second keel members C2 are respectively provided for each planar frame 2 or each plurality of planar frames 2 at the same height for connection. More specifically, two second keel members C2 are respectively provided for each planar frame 2 or each plurality of planar frames 2 at the same height, wherein one second keel member C2 is provided for connection with the side transverse connecting member located on the upper side of a pair of side transverse connecting members 22 of the planar frame 2, and the other second keel member C2 is provided for connection with the side transverse connecting member located on the lower side of a pair of side transverse connecting members 22 of the planar frame 2. The reason for such provision is that, sometimes, due to the small angle between two first keel members C1 adjacent in the first direction (i.e., the extension directions of the two members vary greatly), if only one second keel member C2 is provided for two planar frames 2 adjacent in the first direction and is provided for connection with the end of the planar frame 2 located on the upper side in the first direction and the top of the planar frame 2 located on the lower side at the same time, then, it is possible that a second keel member C2 that meets the installation condition cannot be found. To this end, two second keel components C2 are respectively provided for two first keel components C1 adjacent to each other in the first direction, wherein one second keel component C2 is connected to the end of the planar frame 2 located on the upper side in the first direction, and the other second keel component C2 is connected to the top of the planar frame 2 located on the lower side. In this way, the above situation can be avoided. However, when the extension direction of the two first keel components C1 adjacent to each other in the first direction does not change much, only one second keel component C2 may be provided.

[0052] Fig.13 FIG. 2 is a schematic diagram showing an adjustment method for the first keel connecting member C3 connected to the main structure M. Fig.13As shown in the purple part, sometimes, due to design and other reasons, the first keel connecting member C3 is connected between the first keel member C1 and the main structure M in a non-perpendicular manner to the main structure M. In this way, under the load of the planar plate 1, the first keel connecting member C3 will not only be subjected to in-plane forces, but may also be subjected to out-of-plane forces, which is disadvantageous for the first keel connecting member C3 with low out-of-plane stiffness and strength, and will cause the curtain wall support system S to be unstable, posing certain safety hazards. For this reason, Fig.13 The connection method of the first keel connecting member C3 is adjusted as shown. Specifically, for each column of the first keel members C1, a plane can always be found, which passes through these first keel members C1 and is perpendicular to the main structure M. Then, the first keel connecting member C3 located at the original position is projected onto the plane, so as to find the position of the first keel connecting member C3 on the plane, and the first keel connecting member C3 is reinstalled according to the positioning. That is, through the above adjustment, the first keel connecting member C3 is connected between the first keel member C1 and the main structure M in a plane passing through the first keel member C1 and orthogonal to the main structure M. In this way, it is possible to avoid as much as possible that the first keel connecting member C3 is subjected to out-of-plane forces due to the load of the planar plate 1, etc., thereby improving the stability and safety of the curtain wall support system S.
