Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to an installation structure and method for a curtain wall of a building. Background Art

[0002] Some existing buildings have curtain walls, which are formed by splicing and installing multiple decorative panels. In order to make the overall appearance of the building beautiful, the surfaces of the curtain walls on the same side of the building are often located in the same plane or curved surface. However, since the orientations of the walls on the same side of the building may have angle deviations, and the walls on the same side of the building may have relative convexity, this results in different decorative panels having different angles with the corresponding wall surfaces, that is, for different decorative panels, the angles between the decorative panels and the corresponding wall surfaces may be different, and the decorative panels need to be installed on a substrate fixed on the wall surface of the building, which results in a large amount of complex size and angle calculations before installing the curtain wall, and then the installation structure is designed and produced according to the calculation results, and finally the curtain wall is installed using the produced installation structure.

[0003] This kind of customized design, production and installation process is complicated, the workload is large, and it takes a long time. Each link of the whole process requires high accuracy. In addition, each installation structure produced can only be used in specific projects, and the versatility of each installation structure is weak.

[0004] The Chinese invention patent application with publication number CN101956427A adopts a ball joint connection to adapt to the problem of mismatched angles between the wall and the decorative panel surface, which can solve the above-mentioned problem to a certain extent. However, on the one hand, when installing the unit panels, the support disc is always in a state where it can rotate freely in all directions in space, which increases the difficulty of installing the unit panels. On the other hand, in the installed curtain, it is necessary to limit the freedom between the fixed nodes and the unit panels through the interaction between the unit panels, and to maintain the stability of the entire curtain. The load-bearing capacity of each unit panel is large, which may cause damage to the unit panel, and is therefore only applicable to cases where the unit panels are smaller. Summary of the invention

[0005] One of the purposes of the present invention is to provide a building curtain wall installation structure which can adapt to building surfaces with different angles and relative concavities and convexities and has a strong bearing capacity.

[0006] In order to achieve the above-mentioned purpose, the installation structure of the building curtain wall provided by the present invention includes a base, a decorative panel, a keel and a connecting frame, the keel is connected to the base at least at two locations along a first direction, at least one connection between the keel and the base is a spatial swingable connection with a swing center located at the connection, the first direction is parallel to the main surface of the decorative panel, and the decorative panel is installed on the connecting frame; the keel has a first matching cylindrical surface, and the connecting frame has a second matching cylindrical surface, the cylindrical axis of the first matching cylindrical surface and the cylindrical axis of the second matching cylindrical surface are both along the first direction, and the first matching cylindrical surface and the second matching cylindrical surface are fitted and fixed.

[0007] As can be seen from the above, the present invention can achieve the spatial angle adjustment of the decorative panel relative to the base through the swingable design of the keel relative to the base and the rotatable design of the first matching cylindrical surface and the second matching cylindrical surface in the cylindrical circumferential direction through the structural design of the installation structure of the building curtain wall, so that it is convenient to adjust the main surface direction of the decorative panel to the required direction, so that the installation structure can adapt to the irregular building wall surface; and the keel can be set to a fixed state after the installation with the corresponding bases is completed, and the connection between the connecting frame and the keel is also a fixed connection. The base, the keel and the connecting frame form a stable and reliable installation frame. In this way, on the one hand, when the decorative panel is installed on the installation frame, the decorative panel is installed and connected with the connecting frame in a fixed state, which is conducive to reducing the difficulty of installing the decorative panel. On the other hand, in the installation structure of the present invention, each decorative panel is directly carried by the corresponding keel, without the need to stabilize the curtain wall by means of mutual restraint between the decorative panels, which is conducive to reducing the load of the decorative panel and facilitating the stability and reliability of the structure of the curtain wall. In addition, since the keel structure is stable and reliable and has a strong bearing capacity, the present invention is convenient for assembling large-sized decorative panels to form a curtain wall.

[0008] A preferred solution is that the spatially pivotable connection is a ball joint connection.

[0009] As can be seen from the above, the ball joint connection facilitates the spatial swingable connection between the keel and the base.

[0010] Another preferred solution is that the keel includes a round tube, a conical connecting piece and a connecting stud, the axis of the round tube, the axis of the conical connecting piece and the axis of the connecting stud are all along the first direction, the connection between the connecting stud and the base is a spatially swingable connection, the conical connecting piece is threadedly connected to the connecting stud, and the conical large end of the conical connecting piece is connected to the round tube.

[0011] As can be seen from the above, this can be installed with the help of the round tube fittings of the profile, which is beneficial to improving the economy of the installation structure, and the threaded connection between the tapered connector and the connecting stud facilitates the adjustment of the position of the tapered connector in the first direction, and facilitates the smooth coordination and connection of the round tube fittings, tapered connectors and connecting studs. In addition, it can also reduce the dimensional accuracy requirements of the round tube fittings, tapered connectors and connecting studs in the first direction, which is beneficial to reducing the processing difficulty of the round tube fittings, tapered connectors and connecting studs, and is beneficial to improving economy.

[0012] A further solution is that the round pipe piece is welded to the tapered connecting piece.

[0013] As can be seen from the above, after the positional relationship between the round tube, the conical connector and the connecting stud is determined, the round tube and the conical connector are welded. This can prevent the conical connector from moving relative to the connecting stud in the first direction, making it easier to connect the round tube, the conical connector and the connecting stud to form an integral keel.

[0014] A further solution is that the tapered large end of the tapered connector has a bearing column protruding toward the round tube, and the bearing column is inserted into the tube cavity of the round tube.

[0015] As can be seen from the above, the load applied to the round tube from the decorative panel can be transmitted to the bearing column, which is beneficial to improving the connection strength and reliability between the conical connector and the round tube, and can realize the pre-installation of the conical connector and the round tube by penetrating the bearing column into the tube cavity of the round tube. When the conical connector and the round tube are in the pre-installed state, it is convenient to adjust the positional relationship between the round tube, the conical connector and the connecting studs, and then fix the round tube and the conical connector with the adjusted positional relationship, which is beneficial to reduce the difficulty of matching and connecting the round tube, the conical connector and the connecting studs.

[0016] A further solution is that the base body includes a main cavity body and a cover body distributed along a first direction, the main cavity body and the cover body are assembled to form a mounting cavity, and the cover body has an opening.

[0017] A further solution is that the base has a mounting cavity with an opening facing the first direction, the connecting stud has a protrusion located in the mounting cavity, and the connecting stud passes through the opening and out of the mounting cavity.

[0018] A further solution is that the cross-sectional profile shape of the protrusion along the first direction in the normal direction matches the cross-sectional profile shape of the installation cavity along the first direction in the normal direction, and both are non-circular.

[0019] As can be seen from the above, if the cross-sectional profile shape of the normal of the protrusion along the first direction is a circle, then after the keel and the corresponding substrates are installed and the entire keel extends in a straight line, the protrusion can rotate in the installation cavity around an axis parallel to the first direction. Therefore, the present invention makes the above arrangement, so that the cooperation between the protrusion and the installation cavity wall can limit the rotation of the keel, which is beneficial to improving the stability and reliability of the cooperation between the keel and the substrate.

[0020] Another preferred solution is that the decorative panel includes a glass plate and an auxiliary component fixed to the corner of the glass plate, the auxiliary component has a clamping portion located on the inner side of the glass plate, the clamping portion is clamped and connected to the connecting frame, and the clamping direction of the clamping portion and the connecting frame is along the normal direction of the main surface of the decorative panel.

[0021] As can be seen from the above, this facilitates the coordinated connection between the decorative panel and the connecting piece.

[0022] The second object of the present invention is to provide a building curtain wall installation structure which can adapt to different angles and relative concavities and convexities on the building surface, has a strong bearing capacity and a simple installation process.

[0023] In order to achieve the above-mentioned purpose, the installation method of the building decorative panel of the building curtain wall provided by the present invention adopts the aforementioned installation structure of the building curtain wall, and the method comprises: firstly installing the keel on the base; then fixing the second matching column surface on the first matching column surface; and finally installing the decorative panel on the connecting frame.

[0024] As can be seen from the above, the installation method of the present invention uses the aforementioned installation structure, so that the process of installing the curtain wall is simple and can adapt to irregular building side walls. The curtain wall structure formed by the installation is stable, the glass plate load is small, and it is convenient to use large-size decorative panels to assemble and form the curtain wall.

[0030] Installation structure and installation method of building curtain wall:

[0031] The installation structure of the building curtain wall of this embodiment is used to install the decorative panel 4 on the building to form a curtain wall. For example, the decorative panel 4 is installed on the side wall of the building. Figures 1 to 4 A unified spatial rectangular coordinate system is used to represent the orientation relationship of various components in the installation structure of the building curtain wall, wherein the X-axis direction is the first direction.

[0032] Please refer to Figures 1 to 4 The installation structure of the building curtain wall includes a base 1, a keel 2, a connecting frame 3 and a decorative panel 4. The base 1 is fixed on the side wall of the building. The base 1, the keel 2, the connecting frame 3 and the decorative panel 4 are connected in sequence. In this embodiment, the building is located on the negative side of the Y axis of the base 1.

[0033] Please refer to Figure 1 and Figure 2 The base 1 includes a main cavity 11 and a cover 12. The main cavity 11 is fixedly connected to the side wall of the building. The main cavity 11 extends from the side wall of the building along the positive direction of the Y axis. The positive end of the main cavity 11 in the Y axis has a mounting groove 111 with a notch facing the positive direction of the X axis. The cover 12 covers the notch of the mounting groove 111. The cover 12 and the main cavity 11 form a mounting cavity. Both the main cavity 11 and the cover 12 have openings that penetrate to the mounting cavity along the X axis direction; specifically, the cover 12 and the main cavity 11 are connected by screws 6.

[0034] Please refer to Figure 2 The keel 2 includes a round tube 23, a tapered connector 22 and a connecting stud 21. The axes of the round tube 23, the tapered connector 22 and the connecting stud 21 coincide and are all along the X-axis direction. The connecting stud 21 has a hinged sphere 211 in the middle along the X-axis direction. The hinged sphere 211 is located in the installation cavity. The two ends of the connecting stud 21 along the X-axis direction respectively pass through the two openings of the installation cavity, thereby realizing a ball-jointed connection between the connecting stud 21 and the base 1. The tapered small end of the tapered connector 22 is threadedly connected to the connecting stud 21, and the tapered large end of the tapered connector 22 is welded to the round tube 23.

[0035] The keel 2 often has a combination of multiple groups of round tubes 23, conical connectors 22 and connecting studs 21. Each connecting stud 21 in the keel 2 is ball-jointed to a different base 1. Of course, for the connecting stud 21 at the end of the keel 2 along the X-axis direction, the hinge ball 211 is located at the end of the connecting stud 21, and the connecting stud 21 is only connected to one conical connector 22.

[0036] Preferably, please refer to Figure 2The tapered large end of the tapered connector 22 has a bearing column 221 , which extends toward the corresponding round tube 23 along the X-axis direction, and is inserted into the tube cavity of the round tube 23 .

[0037] Preferably, the round tube 23 is a profile tube.

[0038] For details, please refer to Figure 1 and Figure 2 , the steps of installing the base 1 and the keel 2 can be: the first step: insert the connecting stud 21 into the mounting groove 111 from the notch end (X-axis positive end) of the mounting groove 111, at this time, the hinged ball 211 of the connecting stud 21 is located in the mounting groove 111, and the X-axis negative end of the connecting stud 21 passes through the opening on the main cavity 11; the second step: fix the cover body 12 to the main cavity 11, the cover body 12 is put on the connecting stud 21 through the opening 121 thereon, and the cover body 12 is fixedly connected to the main cavity 11 by using the screw 6, and the X-axis positive end of the connecting stud 21 passes through the opening 121 on the cover body 12; the third step: thread the two conical connectors 22 to the two ends of the connecting stud 21 respectively; the fourth step: connect the two round pipes 23 They are respectively connected to the tapered large ends of the corresponding tapered connectors 22, and the two bearing columns 221 are respectively inserted into the tube cavities of the corresponding round tubes 23; Step 5: Weld the round tube 23 and the tapered connector 22; In the above steps, the third step and the fourth step can also be exchanged.

[0039] The provision of the bearing column 221 is conducive to better realizing the connection between the conical connector 22 and the round tube 23. When the conical connector 22 and the round tube 23 are assembled, the bearing column 221 can also be inserted into the tube cavity of the round tube 23 to realize pre-installation, which is conducive to reducing the difficulty of matching and installing the conical connector 22 and the round tube 23.

[0040] However, since the bearing column 221 and the round tube 23 have an overlapping section in the X-axis direction, the tapered connector 22 and the round tube 23 may interfere with each other when they are installed together. Therefore, in this embodiment, the connecting stud 21 and the tapered connector 22 are set to be threaded, which can facilitate the adjustment of the connection position of the tapered connector 22 on the connecting stud 21. In this way, when executing the third step, the tapered connector 22 is first screwed toward the hinge ball 211 until the tapered connector 22 does not interfere with the installation path of the round tube 23, and then the fourth step is executed to move the round tube 23 to align with the tapered large end of the tapered connector 22, and the position of the tapered connector 22 is adjusted until the bearing column 221 Inserting into the tube cavity of the round tube 23 is conducive to the smooth assembly of the keel 2. When the conical connector 22 and the round tube 23 are in the pre-installed state, it is convenient to adjust the positional relationship of the round tube 23, the conical connector 22 and the connecting stud 21, and then the round tube 23 and the conical connector 22 with the adjusted positional relationship are fixedly connected. In addition, when the dimensions of the round tube 23, the conical connector 22 and the connecting stud 21 in the X-axis direction deviate, the installation can be completed by adjusting the position of the conical connector 22 on the connecting stud 21, which is conducive to reducing the dimensional accuracy requirements of the round tube 23, the conical connector 22 and the connecting stud 21 in the X-axis direction, and is conducive to improving economy.

[0041] Please refer to Figures 1 to 4 The outer circumferential surface of the round tube 23 is a first matching cylindrical surface, the connecting frame 3 has an arc plate portion 31 and a clamping groove portion 32, the arc plate portion 31 has a second matching cylindrical surface, and the second matching cylindrical surface is fitted and fixed on the outer circumferential surface of the round tube 23. Specifically, after the second matching cylindrical surface is fitted to the outer circumferential surface of the round tube 23, the arc plate portion 31 is fixed to the round tube 23 with screws 5.

[0042] Please refer to Figures 1 to 4 The clamping groove portion 32 is located on the side of the arc plate portion 31 facing away from the side wall of the building. The clamping groove portion 32 has a first clamping groove 321 and a second clamping groove 322. The notch of the first clamping groove 321 faces the positive direction of the Z axis, and the notch of the second clamping groove 322 faces the negative direction of the Z axis. The first clamping groove 321 and the second clamping groove 322 both extend along the X-axis direction.

[0043] Please refer to Figure 3 and Figure 4The decorative panel 4 includes a glass plate 41 and an auxiliary component 42. The same decorative panel 4 has four auxiliary components 42, each of which is fixed at the four corners of the glass plate 41. The main surface normal of the glass plate 41 is along the Y-axis direction. The auxiliary component 42 has a clamping portion 411 located on the inner side of the glass plate 41. The clamping portion 411 at the positive end of the Z axis of the glass plate 41 is clamped in the second clamping groove 322 of the connecting frame 3 at the positive end of the Z axis, and the clamping portion 411 at the negative section of the Z axis of the glass plate 41 is clamped in the first clamping groove 321 of the connecting frame 3 at the negative end of the Z axis, thereby realizing the installation of the decorative panel 4.

[0044] Figures 1 to 4 Only the structure of the keel 2 at one substrate 1 is shown. Figures 1 to 4 Only the portion of the round tube 23 close to the base 1 is shown. Figure 3 and Figure 4 Only the portion of the glass plate 41 close to the substrate 1 is shown, and Figure 3 and Figure 4 The four auxiliary components 42 shown in the figure correspond to four adjacent glass plates 41 respectively.

[0045] In the curtain wall formed by installing on the side wall of the building in this embodiment, there are often multiple bases 1, multiple keels 2, multiple connecting frames 3 and multiple decorative panels 4. Each keel 2 has a combination of multiple round tubes 23, multiple conical connecting members 22 and multiple connecting studs 21. The multiple round tubes 23, multiple conical connecting members 22 and multiple connecting studs 21 are assembled to form a keel 2 extending along the X-axis direction. The keel 2 is ball-jointed with different bases 1 at each connecting stud 21. The multiple keels 2 are distributed along the Z-axis direction, and the four corners of each decorative panel 4 are connected to the keel 2 through the connecting frame 3.

[0046] Of course, the side walls of the building where the curtain wall is installed often have relative angle deviations and relative projections and depressions. In order to enable the decorative panels 4 to be assembled to form a flat or curved curtain wall, the main surfaces of the decorative panels 4 often have different angles with the side walls of the building at the corresponding positions. This requires that the installation structures corresponding to different decorative panels 4 be able to adapt to different angle installation requirements.

[0047] In this embodiment, since the connecting stud 21 is connected to the base 1 by a ball joint, the matching angle between the connecting stud 21 and the base 1 can be changed, so the base 1 extending to the keel 2 from different directions can be smoothly installed with the keel 2, and due to the matching design of the first matching cylindrical surface and the second matching cylindrical surface, the connecting frame 3 can be rotated around the axis of the circular tube 23 on the side wall of the circular tube 23, so that the keel 2 can swing relative to the base 1 to adapt to the swing angle requirement of the decorative panel 4 relative to the base 1 in the X-axis direction, and the circumferential position of the connecting frame 3 on the outer circumferential surface of the circular tube 23 can be adjusted to adapt to the decorative panel 4 relative to the base 1. The deflection angle requirement in the Z-axis direction facilitates the decorative panels 4 to adapt to the installation angle according to the requirements of assembling a flat or curved curtain wall, and facilitates the smooth design and installation of the curtain wall on the side wall of the building; in this embodiment, since the installation structure can adapt to the installation angle, the workload and accuracy requirements of angle calculation can be reduced when designing and installing curtain walls for buildings, so that the base 1 of the same size can be suitable for different installation angles with the keel 2, which is conducive to improving the versatility of the installation structure and reducing the difficulty of installing the keel 2, for example Figure 5 As shown, Figure 5 It is a top view schematic diagram of the installation of the keel 2 on the side wall of the building. In FIG5, the side wall surface of the building on which the three substrates 1 are installed is relatively concave and convex, and the orientations thereof have angle differences, resulting in different angles between the three substrates 1 and the keel 2. The present invention can still achieve smooth installation even when the angles between the substrates 1 and the keel 2 are different.

[0048] Of course, the ball joint connection between the base 1 and the keel 2 can also be carried out with reference to the prior art.

[0049] The main surface of the curtain wall in this embodiment is a plane with a normal direction along the Y-axis direction. When the curtain wall needs to have an arc in the Z-axis direction, each keel 2 can be set to be distributed along the arc direction; when the curtain wall needs to have an arc in the X-axis direction, the keel 2 can be set to extend along the arc direction.

[0050] Moreover, after the curtain wall is installed, if the extension direction of the keel 2 is a straight line, for example, in the present embodiment, the keel 2 extends along the X-axis direction, the keel 2 may rotate around an axis parallel to the X-axis direction. At this time, the keel 2 can be fixed after the keel 2 and each base 1 are installed. In this way, there is no need for the keels 2 to be pulled by each other through the decorative panels 4 to maintain stability, which is beneficial to improving the stability of the keel 2, and to making the load of each decorative panel 4 borne by the corresponding keel 2, which is beneficial to reducing the load of the decorative panel 4 and facilitating the installation of large-size decorative panels 4.

[0051] Of course, when the extension direction of the keel 2 is not a straight line, the keel 2 is not easy to rotate around the axis parallel to the X-axis direction, that is, the keel 2 can remain relatively fixed with the substrate 1 after the installation with each substrate 1 is completed, which can also reduce the load of the decorative panel 4 and is also suitable for the installation of large-size decorative panels 4.

[0052] Preferably, the articulated sphere 211 on the connecting stud 21 of the present embodiment can also be replaced by an arcuate body with a rectangular cross-section. Along the X-axis direction, the cross-sectional shape of the arcuate body is rectangular, and the four sides of the rectangular cross-section correspond to the four arcuate surfaces of the arcuate body, and the four arcuate surfaces of the arcuate body are all convex arcuate surfaces; and the shape and size of the inner wall of the installation cavity match the shape and size of the outer contour of the arcuate body. The connecting stud 21 can only swing relative to the sphere in the X-axis and Z-axis directions, and the connecting stud 21 cannot rotate around an axis parallel to the X-axis direction, which is further conducive to making the load of each decorative panel 4 borne by the corresponding keel 2, which is conducive to reducing the load of the decorative panel 4 and facilitating the installation of large-size decorative panels 4. In addition, after the keel 2 and the base 1 are installed together, there is no need to fix the keel 2, which is conducive to simplifying the installation process of the keel 2, reducing the difficulty of installing the keel 2, and reducing the difficulty of installing the curtain wall. In addition, the load that drives the keel 2 to rotate can be dispersed to each base 1, which is further conducive to stable and reliable installation of the keel 2.

[0053] Alternatively, the cross-sectional shape of the normal direction of the arcuate body along the X-axis direction may also be a non-circular shape such as a triangle, an ellipse, a pentagon, etc., which can also prevent the keel 2 from rotating.

[0054] Optionally, the base 1 may also adopt a telescopic and adjustable design, and the specific structure of the telescopic design may be set with reference to the prior art, for example, with reference to the design of the screw rod matching in CN101956427A, which is further conducive to expanding the scope of application of the base 1 and the scope of application of the installation structure of this embodiment.

[0055] Installation method embodiment of building curtain wall:

[0056] The installation method of this embodiment adopts the aforementioned installation structure. The steps of installing and forming a curtain wall by adopting the aforementioned installation structure include: first, installing the keel 2 on the base 1. The specific matching installation method of the keel 2 and the base 1 is recorded in the previous text. Of course, before installing the keel 2 on the base 1, it is necessary to fix each base 1 to the corresponding building, each keel 2 extends along the X-axis direction, and each keel is distributed along the Z-axis direction; then, the connecting frame 3 is fixedly installed on the keel 2. When installing the connecting frame 3, it is necessary to accurately adjust the positions of the connecting frame 3 and the keel 2 and then use screws 5 to fix the connecting frame 3 and the keel 2; finally, the decorative panel 4 is installed on the connecting frame 3. In this embodiment, the decorative panel 4 is inserted into the connecting member 3 along the X-axis direction, wherein the clamping portion at the upper end of the decorative panel 4 is inserted into the second clamping groove of the connecting frame at the upper end of the decorative panel, and the clamping portion at the lower end of the decorative panel 4 is inserted into the first clamping groove of the connecting frame at the lower end of the decorative panel 4.

[0057] The installation method of this embodiment uses the aforementioned installation structure, so that the installation process is simple and can adapt to irregular building side walls. The curtain wall structure formed by the installation is stable, the load on the glass plate 41 is small, and it is convenient to use large-sized decorative panels 4 to assemble and form a curtain wall.

[0058] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
