Description

Technical Field

[0001] The present invention relates to the technical field of building curtain walls, in particular to an open curtain wall system. Background Art

[0002] Building curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels and the supporting structure behind it. The building curtain wall is composed of a supporting structure system and panels, and has a certain displacement capacity relative to the main structure. It is an exterior protective structure or decorative structure of the building that does not share the effects exerted on the main structure.

[0003] The existing building curtain wall is as follows Figure 1 and attached Figure 2 As shown, it includes vertical steel keels 101, connecting angle brackets 201, transverse steel keels 301, waterproof boards 401 and back-bolt stone panel components 501. The back-bolt stone panel components 501 correspond one-to-one with the transverse steel keels 301 and use the transverse steel keels 301 as a supporting structure. In order to ensure that the stone panel is installed stably and does not rotate, it is often necessary to install multiple back-bolts behind the stone panel to cooperate with the transverse steel keels 301. As a result, the number of connection points of the entire curtain wall system increases and the process is complicated. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide an open curtain wall system to solve the problems of the prior art curtain wall system having many connection points and complicated processes.

[0005] To achieve the above-mentioned object, the present invention provides an open curtain wall system, comprising vertical purlins uniformly arranged in a transverse direction, back hanging panels connected to the common outer sides of adjacent vertical purlins, upper hanging grooves extending transversely and extending along the outer sides of the back hanging panels, hangers engaged with the upper hanging grooves and supported on the surfaces of the back hanging panels, screws for connecting the hangers and the back hanging panels, back bolts connected to the outer sides of the hangers, and panels fixed to the back bolts.

[0006] During the construction of the curtain wall system, the back hanging board is connected to the vertical keel, and the panel is connected to the hanger through the back bolt. The panel is moved to the designated installation position by the horizontal movement of the hanger in the hanging groove on the outer side of the back hanging board, and then the hanger and the back hanging board are relatively fixed by screws.

[0007] By adopting this technical solution, the back hanging plate and the hanger cooperate to change the connection form of the panel on the outside of the vertical keel. After the panel is connected to the hanger, the horizontal position of the panel at a specified height can be changed by moving the hanger in the hanging groove on the outside of the back hanging plate, and then fixed in position by screws. This can not only ensure that the panel will not rotate, making the vertical staggered design of adjacent panels more flexible, but also increase the installation efficiency of the panel, and solve the problem of many connection points and complex processes in the existing curtain wall system.

[0008] Furthermore, the curtain wall system also includes a connecting frame and connecting bolts; wherein,

[0009] The connecting frame is U-shaped and is buckled on the outside of the vertical keel, and its two ends are respectively fixed to the vertical keel;

[0010] The connecting bolts are arranged on the connecting frame, and the ends of the back-hanging plates are fixed to the outside of the connecting frame through the connecting bolts.

[0011] By adopting this technical solution, a connecting frame is set up to provide a connection position for the end of the back-hanging plate to ensure a stable connection of the back-hanging plate relative to the vertical purlin. At the same time, the distance between the outer side of the connecting frame and the vertical purlin can be changed to adjust the distance of the back-hanging plate relative to the vertical purlin to adapt to different working conditions. In addition, it also provides the prerequisite for forming a waterproof filling gap between the ends of adjacent back-hanging plates.

[0012] Furthermore, the curtain wall system also includes a sealant;

[0013] The sealant is filled in the gap formed by the ends of two laterally adjacent back-hanging boards and the outer side of the connecting frame.

[0014] By adopting this technical solution, a waterproof filling gap is formed between the ends of two adjacent back-hanging panels and the outer surface of the connecting frame. After the waterproof filling gap is filled with sealant and solidified, combined with the plate-shaped characteristics of the back-hanging panels themselves, horizontal waterproofing of the curtain wall system can be achieved.

[0015] Furthermore, the curtain wall system further includes a plug connector and a plug slot formed on the top and bottom of the back hanging plate, respectively, and the plug connector and the plug slot can be plugged in and matched;

[0016] It also includes a rubber strip that can be sleeved on the outside of the plug connector and embedded in the plug slot.

[0017] By adopting this technical solution, the provision of the plug connector and the plug slot enables the longitudinally adjacent back-hanging panels to have a splicing function, and the waterproof ability of the connection position is provided by the rubber strip, that is, the longitudinal waterproofness of the curtain wall system can be achieved; combined with the transverse waterproofness of the curtain wall system, the entire curtain wall system is waterproof, and there is no need to set up a separate waterproof board to simplify the installation process; the longitudinally adjacent back-hanging panels are connected as a whole through the plug connector and the plug slot, which can reduce the number of connection points between the back-hanging panels and the vertical keels, simplifying the construction process while ensuring the stability of the connection.

[0018] Furthermore, the hanging member includes an upper hanging body and a lower hanging body which are distributed up and down toward one side of the back hanging plate;

[0019] The upper hanging body is hung in the upper hanging groove, and the lower hanging body is supported on the surface of the back hanging plate at the lower side of the upper hanging groove.

[0020] By adopting this technical solution, after the upper hanging body is hooked and matched with the upper hanging groove, the lower hanging body is supported on the surface of the back hanging board to form a rectangular stable structure. On the premise that the hanger is fixedly connected to the panel, the stability of the panel connected to the back hanging board through the single node can be guaranteed, which reduces the number of connection points of the unit panel, thereby achieving the effect of simplifying the construction process and improving construction efficiency.

[0021] Furthermore, the curtain wall system further comprises an adjusting bolt, which is threadedly connected to the top of the upper hanging body;

[0022] The lower end of the adjusting bolt passes through the upper hanging body and is supported on the top of the outer side wall of the upper hanging groove.

[0023] By adopting this technical solution, after the adjusting bolt is rotated relative to the upper hanging body, its length between the upper hanging body and the top of the outer wall of the upper hanging groove will change, which can change the hanging length of the upper hanging body in the upper hanging groove, that is, change the hanging height of the hanger, making the installation flexible and meeting the special installation requirements of the panel.

[0024] Furthermore, the curtain wall system further includes a lower hanging groove formed on the outer side of the back hanging plate and arranged throughout the entire length;

[0025] The lower hanging groove corresponds to the upper hanging groove one by one and is arranged in parallel on the lower side thereof, and the lower hanging groove is plugged and matched with the lower end of the lower hanging body.

[0026] By adopting this technical solution, the lower hanging groove limits the outward movement of the lower hanging body without affecting the support of the lower hanging body on the back hanging board, thereby increasing the stability of the panel installed on the back hanging board through the hanger, and at the same time increasing the hanging accuracy of the hanger on the back hanging board.

[0027] Furthermore, the curtain wall system further includes a fixing member fixedly connected to the top of the upper hanging body;

[0028] The screw is passed through the fixing piece.

[0029] By adopting this technical solution, additional fixings are provided to provide connection positions to ensure that the hanger can be fixed to the specified position on the back hanging board by screws, and the hanger is hung on the back hanging board to achieve a stable connection of the panel on the back hanging board, that is, a stable connection of the panel on the vertical keel.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The back hanging plate and the hanger are used to change the connection form of the panel on the outside of the vertical keel. After the panel is connected to the hanger, the horizontal position of the panel at a specified height can be changed by moving the hanger in the hanging groove on the outside of the back hanging plate, and then fixed in position by screws. This can not only ensure that the panel will not rotate, making the vertical staggered design of adjacent panels more flexible, but also increase the installation efficiency of the panel, and solve the problem of many connection points and complex process of the existing curtain wall system.

[0032] 2. In addition to replacing the horizontal keels, the back-hanging panels also replace the waterproof panels in the existing curtain wall system, which can not only increase the construction efficiency of the curtain wall system, but also solve the problem of conflict between the installation of waterproof panels and the connection structure with the vertical keels.

DETAILED DESCRIPTION

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Please see the attached Figure 3 and 4The present invention provides an open curtain wall system, including vertical purlins 1 evenly distributed along the horizontal direction, back hanging boards 3 connected to the common outer sides of adjacent vertical purlins 1, upper hanging grooves 31 arranged transversely and extending along the outer sides of the back hanging boards 3, hangers 4 that are hung and cooperated with the upper hanging grooves 31 and supported on the surfaces of the back hanging boards 3 at the same time, screws 8 for connecting the hangers 4 and the back hanging boards 3, back bolts 5 connected to the outer sides of the hangers 4, and panels 6 fixed with the back bolts 5; the back hanging boards 3 cooperate with the hangers 4 to change the connection form of the panels 6 on the outer sides of the vertical purlins 1, and after the panels 6 are connected to the hangers 4, the horizontal position of the panels 6 at a specified height can be changed by moving the hangers 4 in the upper hanging grooves 31 on the outer sides of the back hanging boards 3, and then the position can be fixed by screws 8, which can ensure that the panels 6 will not rotate, making the vertical staggered design of adjacent panels 6 more flexible, and can also increase the installation efficiency of the panels 6, thereby solving the problems of many connection points and complicated processes in the existing curtain wall systems.

[0041] Please see the attached Figure 4 The curtain wall system also includes a connecting frame 2 and a connecting bolt 10; wherein the connecting frame 2 is U-shaped and is buckled on the outside of the vertical keel 1, and its two ends are respectively fixed to the vertical keel 1; the connecting bolt 10 is provided on the connecting frame 2, and the end of the back hanging plate 3 is fixed to the outside of the connecting frame 2 by the connecting bolt 10; the connecting frame 2 is provided to provide a connection position for the end of the back hanging plate 3 to ensure a stable connection of the back hanging plate 3 relative to the vertical keel 1, and at the same time, the distance between the outer side of the connecting frame 2 and the vertical keel 1 can be changed to achieve the adjustment of the distance between the back hanging plate 3 and the vertical keel 1 to adapt to different working conditions; in addition, it also provides a prerequisite for forming a waterproof filling gap between the ends of adjacent back hanging plates 3;

[0042] Furthermore, after the connecting frame 2 is connected to the vertical keel 1, it is inconvenient to install the connecting bolt 10. The screw portion of the connecting bolt 10 should be set as one piece with the connecting frame 2, and the screw of the connecting bolt 10 will not rotate relative to the connecting frame 2; accordingly, the back hanging plate 3 should have a bolt connection hole that matches the connecting bolt 10;

[0043] Furthermore, after using the connecting frame 2 to connect the back hanging plate 3 and the vertical purlin 1, the connecting frame 2 is equivalent to an intermediate load connector and needs to have a certain structural strength. Therefore, in addition to its two ends being connected to the vertical purlin 1, there should be a support body between its inner side and the vertical purlin 1 to ensure the supporting strength and load-bearing capacity of the connecting frame 2.

[0044] Please continue to refer to the attached Figure 4The curtain wall system also includes a sealant 11; the sealant 11 is filled in the gap formed by the ends of two adjacent back-hanging boards 3 and the outer side of the connecting frame 2; a waterproof filling gap is formed between the ends of two adjacent back-hanging boards 3 and the outer surface of the connecting frame 2, and after the sealant 11 is filled into the waterproof filling gap and solidified, combined with the plate-shaped characteristics of the back-hanging board 3 itself, the curtain wall system can be horizontally waterproofed;

[0045] Furthermore, in order to ensure that the sealant 11 can provide a waterproof effect, it should be applied to the adjacent connecting bolts 10 while filling the waterproof filling gap to reduce the influence of the connecting bolts 10 on the waterproof effect.

[0046] Please see the attached Figure 5 The curtain wall system also includes a plug connector 33 and a plug groove 34 formed at the top and bottom of the back hanging board 3 respectively, and the plug connector 33 and the plug groove 34 can be plugged in and matched; it also includes a rubber strip 35 that can be sleeved on the outside of the plug connector 33 and embedded in the plug groove 34; the setting of the plug connector 33 and the plug groove 34 enables the longitudinally adjacent back hanging boards 3 to have a splicing function, and the rubber strip 35 provides the waterproof ability of the connection position, that is, the longitudinal waterproofing of the curtain wall system can be achieved; combined with the horizontal waterproofing of the curtain wall system, the entire curtain wall system is waterproof, and there is no need to set up a separate waterproof board to simplify the installation process; the longitudinally adjacent back hanging boards 3 are connected as a whole through the plug connector 33 and the plug groove 34, which can reduce the number of connection points between the back hanging board 3 and the vertical keel 1, while ensuring the connection stability and simplifying the construction process.

[0047] Please continue to refer to the attached Figure 5 The hanger 4 includes an upper hanging body 41 and a lower hanging body 42 distributed up and down toward one side of the back hanging board 3; the upper hanging body 41 is hung in the upper hanging groove 31, and the lower hanging body 42 is supported on the surface of the back hanging board 3 below the upper hanging groove 31; after the upper hanging body 41 is hooked and matched with the upper hanging groove 31, the lower hanging body 42 is supported on the surface of the back hanging board 3 to form a rectangular stable structure. On the premise that the hanger 4 is connected and fixed to the panel 6, the stability of the panel 6 connected to the back hanging board 3 through the single node can be guaranteed, that is, the number of connection points of the unit panel 6 is reduced, thereby achieving the effect of simplifying the construction process and improving construction efficiency.

[0048] Please continue to refer to the attached Figure 5 The curtain wall system also includes an adjusting bolt 9, which is threadedly connected to the top of the upper hanging body 41; the lower end of the adjusting bolt 9 passes through the upper hanging body 41 and is supported on the top of the outer wall of the upper hanging groove 31; after the adjusting bolt 9 rotates relative to the upper hanging body 41, its length between the upper hanging body 41 and the top of the outer wall of the upper hanging groove 31 will change, which can change the hanging length of the upper hanging body 41 in the upper hanging groove 31, that is, change the hanging height of the hanger 4, so that the installation is flexible and can meet the special installation requirements of the panel 6.

[0049] Please continue to refer to the attached Figure 5 The curtain wall system also includes a lower hanging groove 32 formed on the outer side of the back hanging plate 3 and arranged throughout the length; the lower hanging groove 32 corresponds to the upper hanging groove 31 one by one and is arranged parallel to its lower side, and the lower hanging groove 32 is plugged into and matched with the lower end of the lower hanging body 42; the lower hanging groove 32 does not affect the support of the lower hanging body 42 on the back hanging plate 3 while limiting the outward movement of the lower hanging body 42, thereby increasing the stability of the panel 6 installed on the back hanging plate 3 through the hanger 4, and at the same time can increase the hanging accuracy of the hanger 4 on the back hanging plate 3;

[0050] Furthermore, in order to prevent water from accumulating inside the upper hanging groove 31 and the lower hanging groove 32 and affecting the waterproof effect of the back hanging plate 3 itself, water seepage holes should be opened at the bottom of both.

[0051] Please continue to refer to the attached Figure 5 The curtain wall system also includes a fixing part 7 fixedly connected to the top of the upper hanging body 41; screws 8 are passed through the fixing part 7; additional fixing parts 7 are provided to provide connection positions to ensure that the hanger 4 can be fixed to the specified position on the back hanging board 3 by the screws 8, and the hanging of the hanger 4 on the back hanging board 3 realizes the stable connection of the panel 6 on the back hanging board 3, that is, the stable connection of the panel 6 on the vertical keel 1.
