UHPC hanging plate glass composite curtain wall structure and its construction method

Abstract

The present invention discloses a UHPC hanging panel glass combined curtain wall structure and its construction method, which eliminates the masonry on the outer periphery of the building and completely uses UHPC panels as curtain walls on the inside and outside. The UHPC panels themselves have high density and smooth surface, and no decoration is required. The installation is simple and the process is streamlined. On the other hand, the columns and a large number of profiles of the traditional glass curtain wall are eliminated, and the outer and inner hanging panels on the inside and outside are directly combined to form a vertical groove to clamp the glass. The glass curtain wall frame formed by the high strength of UHPC provides a strong force guarantee for the glass. The present invention solves the problem that the construction process of the traditional hanging panel curtain wall is relatively cumbersome.

[0034] See Figure 1 As shown, window openings are formed on the facade of the building structure 1 .

[0035] Continue to refer to Figures 1 to 5 As shown, the present invention provides a UHPC hanging plate glass combined curtain wall structure, including: hanging plate segments 2, prefabricated frame strips 3, and curtain wall glass unit panels 4.

[0036] There are multiple cladding segments 2. The multiple cladding segments 2 are installed in window openings on the facade of the building structure. In this embodiment, the multiple cladding segments 2 are vertically arranged in the window openings. The multiple cladding segments 2 are spaced apart along the circumference of the building structure 1.

[0037] Specifically, the hanging plate segment 2 includes a supporting frame 21 , an outer hanging plate 22 and an inner hanging plate 23 .

[0038] The outer panels 22 and the inner panels 23 are prefabricated UHPC panels.

[0041] In this embodiment, the outer and inner panels 22 and 23 have side flanges 25 extending in opposite directions. A vertical receiving notch is formed on the outer side of one flange 25. The flanges 25 of the outer and inner panels 22 and 23 abut against each other. The other flange 25 and the receiving notch form a vertical receiving slot.

[0042] As a preferred embodiment, the accommodating notch is formed on the edge 25 of the external panel 22 .

[0043] See Figure 3 A plug-in plate 221 is formed on the side of one edge flange 25 of the outer hanging plate 22. A vertically arranged limiting notch is formed on the inner side of the other edge flange 25 of the inner hanging plate 23. The plug-in plate 221 is inserted into the limiting notch.

[0044] See Figure 2 and Figure 3 As shown, the support frame 21 includes: a plurality of columns 211 and a plurality of beams 212. The upper ends of the columns 211 are fixed to the top wall. The lower ends of the columns 211 are fixed to the bottom wall. The plurality of columns 211 are spaced apart along the circumferential direction of the building structure 1.

[0045] A plurality of cross beams 212 are connected between two adjacent columns 211. The plurality of cross beams 212 are arranged in a vertical direction.

[0046] See Figure 5 As shown, the outer hanging plate 22 and the inner hanging plate 23 are hung on the inner side and the outer side of the beam 212 respectively through the hanging parts 24.

[0047] Specifically, an adapter 213 is mounted on the top of the crossbeam 212. The adapter 213 is provided with a supporting flange 214. The upper portion of the hanger 24 is formed with a hook 241 that is hung on the upper portion of the supporting flange 214. The lower portion of the hanger 24 is formed with a reaction plate 242 that supports the lower portion of the supporting flange 214.

[0048] The space between the outer cladding plate 22 and the inner cladding plate 23 is filled with thermal insulation rock wool 215. The thermal insulation rock wool is embedded in the supporting frame 21.

[0049] Two prefabricated frame strips 3 are embedded between two adjacent hanging panel sections 2. They are mounted on the top and bottom walls, respectively. Opposite sides of the two prefabricated frame strips 3 are formed with horizontal slots. The ends of these slots connect to the vertical slots of the two adjacent hanging panel sections 2.

[0050] In this embodiment, embedded plates are respectively embedded in the upper and lower portions of the floor slabs of the building structure. The upper and lower portions of the columns are respectively fixedly connected to the embedded plates of the upper and lower floor slabs. The prefabricated frame strips are fixedly mounted to the embedded plates at the upper or lower portion of the floor slabs.

[0051] The bottom and top of the curtain wall glass unit panel 4 are respectively embedded in the accommodating horizontal grooves. The opposite sides of the curtain wall glass unit panel 4 are respectively embedded in the accommodating vertical grooves of two adjacent hanging plate sections 2.

[0052] As a preferred embodiment, the curtain wall glass unit panel 4 is a laminated glass panel.

[0053] See Figure 3 As shown, sealing strips are provided between the opposite sides of the curtain wall glass unit panel 4 and the side walls of the accommodating horizontal groove and the accommodating vertical groove.

[0054] The present invention provides a construction method of a UHPC hanging plate glass composite curtain wall structure, comprising the following steps:

[0055] S1: A plurality of supporting frames 21 are installed in window openings formed on the facade of the building structure 1 . The plurality of supporting frames 21 are arranged at intervals along the circumferential direction of the building structure 1 .

[0056] S2: hoisting the external cladding plate 22 on the outside of the building structure 1 and hanging the external cladding plate 22 on the outside of the supporting frame 21 .

[0057] S3: Install multiple prefabricated frame strips 3 in the window opening. The prefabricated frame strips 3 are embedded between two adjacent hanging plate sections 2. Multiple prefabricated frame strips 3 are respectively installed on the top wall and the bottom wall. The two ends of the accommodating transverse groove of the prefabricated frame strips 3 are respectively connected to the accommodating notches of the external hanging plates 22 on the two adjacent supporting frames 21.

[0058] S4: The curtain wall glass unit panel 4 is vertically installed in the window opening indoors of the building structure 1, so that the upper and lower parts of the curtain wall glass unit panel 4 are respectively embedded in the accommodating horizontal grooves of the prefabricated frame strips 3 on the top and bottom walls, and the opposite sides of the curtain wall glass unit panel 4 are respectively embedded in the accommodating notches of the external panels 22 on the two adjacent supporting frames 21.

[0059] S5: Hang the inner hanging panel 23 on the inner side of the supporting frame 21 in the interior of the building structure 1 so that the edge flange 25 of the inner hanging panel 23 abuts against the edge flange 25 of the outer hanging panel 22 and presses against the inner side of the curtain wall glass unit panel 4.

[0060] The UHPC panel-glass composite curtain wall structure of the present invention eliminates the masonry surrounding the building's perimeter. UHPC panels are used entirely inside and outside as curtain walls, with insulating rock wool inserted between the outer and inner panels to form a sandwich-core, insulated curtain wall panel. The high density and smooth surface of the UHPC panels negate the need for further decoration. Furthermore, the columns and numerous profiles of traditional glass curtain walls are eliminated, with the outer and inner panels combined to form vertical grooves to hold the glass. The high strength of UHPC creates a glass curtain wall frame that provides strong support for the glass.

[0061] The seals in the vertical grooves are made of EPDM strips, which can protect the UHPC inner panels from collision damage during installation and increase the overall tightness of the UHPC part. At the same time, setting the joints on the indoor side also reduces the risk of curtain wall leakage.

[0062] The UHPC inner and outer cladding panels feature a Z-shaped seam with a low outer edge and a high inner edge at the edge flanges, effectively preventing rainwater from entering the panels. Seals (EPDM strips) running the length of the prefabricated frame's transverse grooves prevent damage during installation. The tight fit of the strips on either side of the panel seam creates an effective waterproof barrier.

[0063] Double-layer UHPC panels are filled with the insulation rock surface. The thickness of the insulation rock surface is determined by design calculations. The insulation rock surface is installed on the frame to ensure that it is firmly fixed, thereby ensuring that the UHPC curtain wall system meets energy-saving requirements.

[0064] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
