Description

Technical Field

[0001] This invention relates to a four-sided supported all-glass curtain wall and its construction method. Background Technology

[0002] A glass curtain wall is a building envelope or decorative structure that is supported by a structural system and can have a certain displacement capacity relative to the main structure, without sharing the load of the main structure. There are two types of glass walls: single-layer and double-layer. Glass curtain walls are an aesthetically pleasing and novel method of building wall decoration and a prominent feature of the modernist high-rise building era.

[0003] Currently, during the installation of glass curtain walls, the upper and lower installation structures are secured to the vertical glass ribs using angle brackets and bolts. These angle brackets also have multiple holes for adjusting the height of the vertical glass ribs. However, in the event of natural disasters such as earthquakes, the existing structure lacks corresponding stress-relief mechanisms, causing settlement and displacement of the glass curtain wall and other building structures, potentially leading to collapse and breakage. Therefore, it is necessary to design a glass curtain wall installation structure that prevents displacement or settlement during earthquakes, ensuring the overall structural safety. Utility Model Content

[0004] This invention provides a four-sided supported all-glass curtain wall and its construction method, which can effectively solve the above problems.

[0005] This invention is implemented as follows:

[0006] A four-sided supported all-glass curtain wall includes a steel plate and horizontal and vertical glass ribs that support the four sides of the operable glass panes. The horizontal and vertical glass ribs are fixed by stainless steel clamps. The operable glass panes are integrally formed with aluminum profile window sashes around their perimeter and fit and seal with aluminum profile window frames set on the horizontal and vertical glass ribs. The aluminum profile window frames are fixed to the horizontal and vertical glass ribs by stainless steel bolts. The aluminum profile window sashes are also provided with handles for opening and closing the operable glass panes.

[0007] One end of the vertical glass rib also includes a support assembly, which comprises a clamping member consisting of two sets of L-shaped clamping plates for clamping the vertical glass rib and fixing it with bolts. Each set of L-shaped clamping plates has two sets of adjusting grooves on its vertical surface for adjusting the height of the first support plate. The upper end of the first support plate is provided with several first springs, and the other ends of these springs are fixedly connected to the second support plate. The upper surface of the second support plate is connected to the bottom end of the vertical glass rib, weakening the downward vertical force on the rib. The four corners of the first support plate are integrally formed with protruding plates, one end of which is provided with a supporting inclined plate, which can be rotated and adjusted by a fixed rotating component to increase the contact area of ​​the supporting inclined plate.

[0008] Two sets of L-shaped clamps are fixedly provided with convex limiting members on the transverse surface away from the first support plate, and a shaft pin passes through them. The shaft pin passes through the convex limiting members on both sides and the vertical plate fixed on the steel plate in sequence, and is inserted into the second spring center hole on the outside of the vertical plate. When the displacement occurs, the convex limiting members slide through the shaft pin to weaken the earthquake impact. The shaft pin passes through the vertical plate and is inserted into the second spring center hole.

[0009] A ring is fitted onto the outer wall of the shaft pin at a position between the two sets of convex limiting members. Two sets of support frames are integrally formed on the outer wall of the ring. An abutment rod connected to the middle of the bottom surface of the first support plate is fixedly provided on the upper outer wall of the ring to improve the fit between the second support plate and the vertical glass rib.

[0010] This invention also provides a construction method for a four-sided supported all-glass curtain wall, applicable to any of the four-sided supported all-glass curtain walls described above, comprising the following steps:

[0011] S1. Measurement and layout;

[0012] S2. Install and position the embedded parts to reduce the positional error of the embedded parts, so that the elevation deviation is less than 9mm and the left and right displacement is less than 20mm;

[0013] S3. The columns are installed from bottom to top;

[0014] S4. Fix the vertical glass ribs using clamps, bolts, and other fixing structures on the columns. When installing the second vertical glass rib, fix it to the first vertical glass rib using clamps. Then, connect the third vertical glass rib to the support assembly. After completion, connect and fix the horizontal glass ribs to multiple sets of vertical glass ribs using stainless steel clamps.

[0015] S5. Install the aluminum profile window frame and install the aluminum profile window sash, which is pre-assembled with glass, inside the aluminum profile window frame. The four sides of the aluminum profile window frame are connected to the horizontal and vertical glass ribs by stainless steel bolts.

[0016] S6. Install the aluminum profile window sashes one by one until all aluminum profile window sashes are installed;

[0017] S7. Inject glue.

[0018] As a further improvement, step S4 specifically includes the following steps:

[0019] S401. Connect and fix the steel plate to the embedded part through the reserved groove;

[0020] S402. Clamp one end of the vertical glass rib with an L-shaped clamp, adjust the first support plate to a suitable position, fix the support inclined plate with the second fixing member, the top surface of the second support plate is in contact with the bottom surface of one end of the vertical glass rib, and then rotate the first fixing member up and down through the internal thread on the mating plate, and make one end of the first fixing member connected to the four corner threads at the lower end of the first support plate.

[0021] The beneficial effects of this invention are:

[0022] (1) By setting horizontal and vertical glass ribs, the structure composed of aluminum profile window frame, aluminum profile window sash and glass curtain wall can be fixed well and the four sides of the structure can be supported, which is safe and reliable. The aluminum profile window frame and the vertical and horizontal glass ribs of the glass curtain wall are mechanically connected to meet the structural stress requirements. It is suitable for the installation of various large-size opening sashes. At the same time, the horizontal glass ribs act as aluminum profile beams, but reduce the obstruction of the view and better preserve the architectural style of the all-glass curtain wall.

[0023] (2) When the entire structure undergoes horizontal displacement, the two sets of L-shaped clamps slide on the pivot pins and weaken the impact of the seismic force under the action of the second spring, thereby reducing the stress intensity of the vertical glass ribs; after the earthquake, the vertical glass ribs are restored to their vertical state under the balanced force of the two sets of second springs. Therefore, when the entire glass curtain wall system structure shakes violently, the vertical glass ribs will only shake slightly or remain still. When the vertical glass ribs are stable, the horizontal glass ribs will also be stable. Thus, the stability of the entire glass curtain wall system will not be greatly damaged, and the safety factor will be improved.

[0024] (3) During an earthquake, the vertical glass ribs are subjected to a vertical force from top to bottom. This force is transmitted to the second support plate and gradually weakened by the elastic potential energy generated by the compression of several first springs. Part of the vertical force is also transmitted to the two sets of L-shaped clamps through the first support plate and the first fixing member. The final force point of the L-shaped clamps is the steel plate, which guides the force to the ground, thereby achieving the effect of force dissipation.

[0025] (4) When the angle between the support inclined plate and the L-shaped clamp is 10 to 15 degrees, the support area of ​​the support inclined plate is the largest. When the support area of ​​the four sets of support inclined plates is the largest, it means that the structure such as the first support plate is more stable and has better stress resistance.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Reference Figure 1 As shown, a four-sided supported all-glass curtain wall includes a steel plate 6 and horizontal glass ribs 1 and vertical glass ribs 2 that support the four sides of the operable glass sash 4. The horizontal glass ribs 1 and vertical glass ribs 2 are fixed by stainless steel clamps 3. The operable glass sash 4 is integrally formed with aluminum profile window sashes around its four sides and fits and seals with the aluminum profile window frames set on the horizontal glass ribs 1 and vertical glass ribs 2. The aluminum profile window frames are fixed to the horizontal glass ribs 1 and vertical glass ribs 2 by stainless steel bolts. The aluminum profile window sashes are also provided with handles for opening and closing the operable glass sash 4.

[0037] Specifically, the horizontal glass ribs 1 and vertical glass ribs 2 effectively fix the structure composed of aluminum profile window frames, aluminum profile window sashes, and glass curtain walls, and support the four sides of this structure, ensuring safety and reliability. The aluminum profile window frames and the vertical and horizontal glass ribs of the glass curtain wall are mechanically connected to meet the structural stress requirements and are suitable for the installation of various large-size operable sashes. At the same time, the horizontal glass ribs 1 act as aluminum profile beams, but reduce the obstruction of the view, thus better preserving the architectural style of the all-glass curtain wall.

[0038] Reference Figure 2-3As shown, a reserved groove 7 is provided on the steel plate 6. Specifically, the reserved groove 7 is connected to an embedded part that is pre-fixed in the concrete, thereby fixing the steel plate 6 and allowing it to serve as a supporting base. A vertical plate 8 is fixedly installed on the steel plate 6 at a position between the two sets of reserved grooves 7, and mating plates 9 for connecting with the third fastener 10 are fixedly installed on both sides of the vertical plate 8.

[0039] One end of the vertical glass rib 2 also includes a support assembly 5, which comprises a clamping member consisting of two sets of L-shaped clamping plates 50 for clamping the vertical glass rib 2 and fixing it with bolts. Specifically, the vertical width of the two sets of L-shaped clamping plates 50 is the same as that of the vertical glass rib 2. Each set of L-shaped clamping plates 50 has two sets of adjusting grooves 51 on its vertical surface for adjusting the height of the first support plate 54. Specifically, the two sets of adjusting grooves 51 include, but are not limited to, two sets, and may be three sets or more, increasing or decreasing according to actual needs. The upper end of the first support plate 54 is provided with several first springs 55, and the other ends of the several first springs 55 are fixedly connected to the second support plate 56. The upper end face of the second support plate 56 is connected to the bottom end of the vertical glass rib 2 by screws, thereby weakening the vertical force from top to bottom on the vertical glass rib 2. Specifically, during an earthquake, the vertical glass rib 2 experiences a downward vertical force, which is transmitted to the second support plate 56. Under the elastic potential energy generated by the compression of several first springs 55, the vertical force is gradually weakened. Part of the vertical force is also transmitted to the two sets of L-shaped clamps 50 through the first support plate 55 and the first fixing member 53. The final stress point of the L-shaped clamps 50 is the steel plate 6, which guides the force to the ground, thus achieving the effect of force dissipation. The four corners of the first support plate 54 are integrally formed with protruding plates 57. One end of the protruding plate 57 is provided with a supporting inclined plate 59, which is adjusted by the fixed rotating member 58 to increase the contact area of ​​the supporting inclined plate 59. Specifically, the fixed rotating component 58 also includes a rotating rod and a limiting cap. The rotating rod passes through the protruding plate 57 and the supporting inclined plate 59, and the limiting cap tightens the internal thread on it with the external threads at both ends of the extending rotating rod to limit its rotation, preventing the supporting inclined plate 59 from rotating again. The angle formed by the supporting inclined plate 59 and the L-shaped clamping plate 50 is 10 to 15 degrees. Specifically, when the angle formed by the supporting inclined plate 59 and the L-shaped clamping plate 50 is 10 to 15 degrees, the supporting area of ​​the supporting inclined plate 59 is the largest. When the supporting area of ​​the four sets of supporting inclined plates 59 is the largest, it means that the structure such as the first supporting plate 54 is more stable and has better stress resistance.

[0040] Furthermore, when the height of the vertical glass rib 2 changes, the angle formed by the supporting inclined plate 59 and the L-shaped clamp 50 also changes accordingly. At this time, the supporting area of ​​the supporting inclined plate 59 changes, which may affect the stress of the entire structure. However, through the setting of the first fixing member 53 on the connecting plate 52, one end of which can be screwed into the bottom of the first supporting plate 54, the entire structure of the first supporting plate 54 can be supported, ensuring that the application of the entire structure will not be affected by the change in the supporting area of ​​the supporting inclined plate 59.

[0041] Two sets of L-shaped clamping plates 50 are fixedly equipped with convex limiting members 511 at positions away from the first support plate 54 on their transverse surfaces, and a shaft pin 512 passes through them. During displacement, the convex limiting members 511 slide through the shaft pin 512, weakening the seismic impact. The shaft pin 512 passes through the vertical plate 8 and inserts into the center hole of the second spring 513. Specifically, when the entire structure undergoes horizontal displacement, the two sets of L-shaped clamping plates 50 slide on the shaft pin 512 and, under the action of the second spring 513, weaken the impact of the seismic force, thereby reducing the stress on the vertical glass rib 2. After the earthquake, the vertical glass rib 2 returns to its vertical state under the balanced force of the two sets of second springs 513. Therefore, when the entire glass curtain wall system structure shakes violently, the vertical glass rib 2 will only shake slightly or remain stationary. When the vertical glass rib 2 stabilizes, the transverse glass rib 1 will also stabilize. Thus, the stability of the entire glass curtain wall system will not be excessively damaged, improving the safety factor. A connecting plate 52 is fixedly installed on the inner side of the vertical surface of the L-shaped clamp 50, away from the first support plate 54, for threaded connection with the first fixing member 53. The small end of the first fixing member 53 is threaded to the four corners of the lower end face of the first support plate 54, further supporting the first support plate 54 and improving its strength. A collar 11 is sleeved on the outer wall of the shaft pin 512, located between the two sets of convex limiting members 511. Two sets of support frames 12 are integrally formed on the outer wall of the collar 11. An abutment rod 13 is fixedly installed on the upper outer wall of the collar 11, which is connected to the middle of the bottom surface of the first support plate 54, improving the fit between the second support plate 56 and the vertical glass rib 2. The abutment rod 13 is a telescopic support rod that rises as the first support plate 54 rises. Specifically, the abutment rod 13 includes two rods and a bolt (not shown in the figure). One rod is inserted into the other rod and slides up and down through a groove inside the other rod. Both rods have threaded holes on their outer walls. When one rod extends or retracts and contacts the bottom of the first support plate 54, the threaded holes on the two rods are aligned, and the bolt is screwed into the threaded hole to fix the two rods, thereby further improving the stability of the vertical glass rib 2 on the first support plate 54.

[0042] Furthermore, the arrangement of the support frame 12 and the collar 11 not only makes the shaft pin 512 more stable, but also improves the support effect of the abutment rod 13.

[0043] This invention also provides a four-sided supported all-glass curtain wall and a construction method thereof, applicable to any of the four-sided supported all-glass curtain walls mentioned above, comprising the following steps:

[0044] S1. Measurement and layout;

[0045] S2. Install and position the embedded parts to reduce the positional error of the embedded parts, so that the elevation deviation is less than 9mm and the left and right displacement is less than 20mm;

[0046] S3. The columns are installed from bottom to top;

[0047] S4. Fix the vertical glass rib 1 by means of the clamps, bolts and other fixing structures on the column.

After completion, connect and fix the horizontal glass rib 1 to multiple sets of vertical glass ribs 2 by means of stainless steel clamps.

Then rotate the first fixing member 53 up and down through the internal thread on the mating plate 52, and connect one end of the first fixing member 53 with the four corner threads at the lower end of the first support plate 54.
