Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, in particular to a reverse-installed curtain wall. Background Art

[0002] Conventional facade curtain wall vertical frames are installed on the inner side of the panel as the main load-bearing components, which transmit force to the main structure through connectors. Decorative strip components are provided on the outer side of the panel for decorative effects. However, there are disadvantages such as large consumption of profiles, increased material consumption of the inner vertical frames due to the decorative strips being subjected to other loads, and the need for additional hardware accessories for connection.

[0003] In addition, the vertical frames and horizontal frames of conventional curtain walls are all set on the indoor side, and a skeleton is formed by connecting components to support the panels. If the panels are damaged or need to be replaced for other reasons, they need to be removed and replaced from the outdoor side due to obstruction of the skeleton. Maintenance workers and panels need to be hoisted from high altitude from the outdoor side, which has high safety risks and high replacement costs for a single panel. It is also inconvenient for installation and subsequent maintenance and inspection. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a reverse-installed curtain wall that is vertically visible and horizontally hidden, saves profiles, and has reasonable force.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A reverse-mounted curtain wall comprises a vertical frame arranged outdoors, a horizontal frame arranged indoors, a load-bearing support bar fixedly connected to the vertical frame, and a panel matched with and mounted on the load-bearing support bar, wherein the horizontal frame and the vertical frame are fixedly connected via a short vertical transition piece located indoors; the short vertical transition piece comprises a first side surface parallel to the extension direction of the horizontal frame and a second side surface perpendicular to the extension direction of the horizontal frame, the first side surface is tightly connected to the vertical frame, and the second side surface is tightly connected to the horizontal frame.

[0007] Different from the existing curtain wall in which the horizontal frame and the vertical frame are located on the same side, the horizontal frame and the vertical frame of the present invention are on different sides. The vertical frame is set on the outside of the panel to achieve the effect of the facade decorative strip. The vertical frame located outdoors is connected to the load-bearing support strip to bear the load. The vertical frame also serves as an external decorative sunshade and a load-bearing component. Only the horizontal frame exists indoors, eliminating the indoor vertical frame, saving the consumption of profiles and raw materials. Compared with the prior art, the vertical frame usage of the present invention can be reduced by half.

[0008] The material of the panel of the present invention is not limited, and the panel material can be a commonly used curtain wall panel such as a glass panel.

[0009] The vertical frame located on the outdoor side serves as a load-bearing component and has the function of resisting direct wind and lateral wind, and also has the function of sunshade.

[0010] The first side surface and the second side surface enclose a frame structure with upper and lower openings.

[0011] Furthermore, the horizontal frame is in a "曰" shape structure, including an outer frame and a horizontal plate located inside the frame; the second side surface is fixedly connected to the horizontal plate through a connecting corner code.

[0012] In the reverse-mounted curtain wall of the present invention, the middle panel can be directly replaced from indoors, and the replacement is convenient and safe;

[0013] The specific replacement method includes the following steps:

[0020] (g) Install the top plate of the horizontal frame onto the main body of the horizontal frame.

[0021] The short vertical adapter and the horizontal frame connected to the short vertical adapter are arranged in a straight line.

[0022] The short vertical adapter and the horizontal frame can be designed to have the same size and dimensions. The side of the curtain wall located indoors is a horizontal straight line in terms of visual effect, making it more beautiful and concise visually.

[0023] The vertical frame includes a vertical frame body located outdoors and a connecting part connected to the vertical frame body; the end surface of the connecting part is fixedly connected to the first side surface of the short vertical adapter through a fastener, and the two side surfaces of the connecting part are respectively fixedly connected to the load-bearing support bar through fasteners.

[0024] The shape of the vertical frame body is square, arc-shaped, fusiform, or other shapes that can be extruded or spliced in the prior art.

[0025] The connecting part of the vertical frame serves to connect with the short vertical adapter and the load-bearing support bar. The vertical frame body is located outdoors, with the effect of an exterior decoration strip, and its shape is not restricted. It can be designed into various required forms such as square, arc-shaped, fusiform, etc. according to the appearance effect, being flexible and variable.

[0026] The vertical frame further comprises a sealing plate fixedly connected to the vertical frame body, and the connecting portion is arranged in a cavity formed by the sealing plate and the vertical frame body.

[0027] A profile adapter and a thermal insulation pad are provided between the end surface of the connecting part and the first side surface of the short vertical connecting part; the connecting part of the vertical frame, the first side surface of the short vertical connecting part, the profile adapter and the thermal insulation pad are fixedly connected by fasteners, which are mechanical bolts.

[0028] In order to avoid glass wear, installation inconvenience and glass breakage caused by direct contact between the panel and the profile adapter, a rubber strip can be added between the profile adapter and the panel. The rubber strip acts as a cushion to facilitate panel installation.

[0029] There are a plurality of vertical frames, and the upper and lower vertical frames are positioned and connected by inserting core pieces.

[0030] The connecting part of the vertical frame is provided with a mounting cavity matching the shape of the insert, the lower end of the insert is fixedly connected to the connecting part of the vertical frame below by a fastener, and the upper end of the insert is inserted into the mounting cavity of the vertical frame above, which is used to position the vertical frame above. The upper and lower vertical frames are positioned by the insert, which facilitates the installation of the vertical frames and improves the installation efficiency and accuracy.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] (1) The curtain wall of the present invention has vertical frames located on the outdoor side and horizontal frames located on the indoor side, which presents a vertically visible and horizontally invisible effect on the outdoor side, and the appearance of the vertical frame body located outdoors can flexibly realize a variety of facade line effects;

[0033] (2) The vertical frame of the curtain wall of the present invention located outdoors can simultaneously realize the functions of external line decoration and load-bearing, thereby eliminating the load-bearing vertical frame set indoors, and the amount of vertical frame can be reduced by half, which can significantly save the construction cost and has the effect of energy saving and emission reduction;

[0034] (3) The load-bearing support strips in the curtain wall of the present invention are connected to the vertical frames with load-bearing functions by screws, and the vertical frames are connected to the horizontal frames by short vertical transition pieces. The center of gravity of the panel of the present invention is located in the middle of the horizontal and vertical frames, so as to avoid eccentric force causing large torsional shearing on the supporting components and the connecting parts, and the horizontal frames and vertical frames play an internal and external clamping and protective role on the panel. Therefore, the present invention ensures the rationality of force transmission and force bearing on the basis of realizing vertical visibility and horizontal concealment, and the installation is simple and reliable, and has the advantages of high installation efficiency;

[0035] (4) There are only horizontal frames in the room, eliminating vertical frame profiles, which increases the indoor usable space;

[0036] (5) The vertical frame in the present invention has the functions of resisting crosswind and shading. Since the vertical frame protrudes from the outer side of the glass curtain wall, it can prevent oblique sunlight from entering the room, thus having the function of shading, which is conducive to maintaining the indoor temperature stable and preventing the indoor temperature from being too high;

[0037] (6) When replacing panels, such as glass panels, of the curtain wall of this embodiment, the replacement can be completed indoors, and the replacement steps are simple and convenient, thereby improving the replacement efficiency and the safety of the entire replacement process.

DETAILED DESCRIPTION

[0043] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0044] Example

[0045] A reverse mounted curtain wall, such as Figure 1As shown, it includes two paired upper and lower vertical frames 100 arranged outdoors, two paired horizontal frames 106 arranged indoors, a load-bearing support bar 103 fixedly connected to the vertical frames 100, and a panel 105 matched and installed on the load-bearing support bar 103. In this embodiment, the panel 105 is a glass panel, the horizontal frame 106 and the vertical frame 100 are fixedly connected by a short vertical transition piece 110 located indoors, and the ends of the two vertical frames 100 are respectively fixedly connected to the building, which can be achieved by adopting the existing connection method of the glass curtain wall; the short vertical transition piece 110 is a frame-like structure, which includes a first side surface parallel to the extension direction of the horizontal frame 106 and a second side surface perpendicular to the extension direction of the horizontal frame 106, the first side surface is fastened to the vertical frame 100, and the second side surface is fastened to the horizontal frame 106; as shown Figure 2 As shown, the horizontal frame 106 is a "Y"-shaped structure, including an external frame 104 and a horizontal board 102 located inside the frame; the second side is fixedly connected to the horizontal board 102 through an L-shaped connecting angle 109; visually, the short vertical adapter 110 and the horizontal frame 106 connected to the short vertical adapter 110 are arranged in a straight line. And from the overall point of view, there is only a horizontal frame but no vertical frame in the room, which saves one profile in the room, and correspondingly increases the indoor usable space. Figure 3 shown.

[0046] The vertical frame 100 includes a vertical frame body located outdoors, a connecting portion connected to the vertical frame body, and a sealing plate 101 fixedly connected to the vertical frame body. The connecting portion is arranged in a cavity formed by the sealing plate 101 and the vertical frame body. The end face of the connecting portion is fixedly connected to the first side face of the short vertical transition piece 110 by a mechanical bolt 111, and the two side faces of the connecting portion are fixedly connected to the load-bearing support bar 103 by fasteners. The panel is matched and mounted to the load-bearing support bar 103, so the connecting portion of the vertical frame 100 plays a load-bearing role. The shape of the vertical frame body located outdoors can be selected as square, arc or shuttle shape according to needs. Flexible and changeable, achieving the effect of the facade decorative strip; because the vertical frame 100 plays the role of both load-bearing and external decoration, the entire curtain wall only sets up vertical frames on the outdoor side, and omits vertical frames indoors. Compared with the conventional vertical frame set on the inner side of the panel and the decorative strip set on the outer side, the material of the inner profile can be saved, and the material saving is considerable; and in addition to the load-bearing and decorative functions, the vertical frame is also designed to have the function of resisting lateral wind and sunshade. Since the vertical frame protrudes on the outer side of the glass curtain wall, it can prevent oblique sunlight from shining into the room, so it has the function of sunshade, which is conducive to maintaining the indoor temperature stable and preventing the indoor temperature from being too high, such as Figure 4 shown.

[0047] There is a profile adapter 107 and a heat insulation spacer 108 between the end face of the connecting part and the first side face of the short vertical adapter 110; the connecting part of the vertical frame 100, the first side face of the short vertical connecting piece, the profile adapter 107 and the heat insulation spacer 108 are fixedly connected by fasteners, and the fasteners are machine bolts 111; the heat insulation spacer 108 is of an I-shaped structure and is correspondingly installed in the installation cavity inside the profile adapter 107. A rubber strip 112 is arranged between the outside of the profile adapter 107 and the panel 105 to prevent the panel 105 from being worn and to facilitate the installation of the panel 105.

[0048] There are several vertical frames 100 in the whole curtain wall, and the upper and lower vertical frames 10 are positioned and connected by an insert core 113; an installation cavity matching the shape of the insert core 113 is arranged inside the connecting part of the vertical frame 100. The lower end part of the insert core 113 is fixedly connected to the connecting part of the vertical frame below by a fastener, and the upper end of the insert core 113 extends into the installation cavity of the vertical frame above for positioning the vertical frame above, which can improve the installation efficiency and ensure accurate installation.

[0049] The reverse-mounted curtain wall of this embodiment can directly replace the panel from the indoor side; the specific replacement method includes the following steps:

[0050] (a) Open the top plate of the horizontal frame 106 with a "曰"-shaped structure;

[0051] (b) Remove the connecting screw between the connecting angle code 109 and the horizontal frame 106, and remove the entire horizontal frame 106. At this time, the connecting angle code 109 remains screwed to the second side face of the short vertical adapter 110;

[0052] (c) Remove the machine bolt 111 between the short vertical adapter 110 and the vertical frame 100, and remove the short vertical adapter 110. At this time, the panel 105 is completely exposed on the indoor side;

[0053] (d) Take out the panel 105 to be replaced on the load-bearing support bar 103 and replace it with a new panel 105;

[0054] (e) Fasten the short vertical adapter 110 and the vertical frame 100 with machine bolts 111;

[0055] (f) Fasten the connecting angle code 109 and the horizontal frame 106 with connecting screws;

[0056] (g) Install the top plate of the horizontal frame 106 onto the main body of the horizontal frame 106 to complete the replacement.

[0057] On the basis that the curtain wall of this embodiment can flexibly achieve various facade line effects in appearance, it can ensure the rationality of structural force transmission and reception, is simple and reliable to install, has the effect of energy conservation and emission reduction, and can significantly save the construction cost for the construction unit.

[0058] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
