Abstract
The utility model provides a steel and aluminum combination fireproof section bar for a curtain wall, which belongs to the filed of building materials. The combination section bar is composed by connecting an inverted U-shaped section bar pair at the outer side of the indoor. The external layer of the outer side section bar of the indoor is an aluminum section bar, and the internal layer is a steel section bar. The internal layer steel section bar of the abutting surface of the beginning end of the inner side inverted U-shaped section bar pair of the indoor is provided with an inward sealing gasket groove and an outward flange. Two sides of the outward flange is provided with a glass panel installation notch, and the top end of the flange is provided with an installing hole. An internal layer steel section bar of the abutting surface of the beginning end of the inner side inverted U-shaped section bar pair of the outdoor is provided with an inward sealing gasket groove. The abutting surface of the beginning end of the inner side inverted U-shaped section bar pair of the indoor is fastened and connected through a self-tapping screw. The curtain wall glass panel is firmly clamped in the glass panel notch. The steel and aluminum combination fireproof section bar for a curtain wall is advantageous in that the decorative effect of the external layer aluminum section bar is good; the internal layer galvanizing steel section bar is good in bearing capacity and fire resistance; with the arrangement of the sealing gasket between the abutting faces of the indoor outer side section bar pair, the clamping of the glass panel is firmer and more stable, and the sealing and anticorrosion effect is good.
Description
Technical field
The utility model curtain wall belongs to building material field with steel aluminium combination fire prevention section bar, is specifically related to composite material.
Background technology
The heavy construction fire incident repeatedly takes place in China in recent years, and building curtain wall is burnt rapidly, causes fire spreading, and the people's life and property caused heavy casualty and loss.The section bar that in present building curtain wall, uses is mainly aluminium alloy extrusions and steel profile.Traditional aluminium alloy extrusions is corrosion-resistant, good decorating effect as the characteristics of curtain wall support structure, but mechanical properties such as rigidity and intensity are relatively poor, and fusing point is low, and fireproof performance is bad, should not be independent of the curtain wall main body frame supporting construction that fire protection requirement is arranged; Though adopt steel profile good as mechanical properties such as curtain wall support structure rigidity and intensity, fusing point is high, fire resistance is good, perishable, decorative effect is poor, therefore press for exploitation safety, fire prevention and specious Building Curtain Wall Structures material.
The utility model content
The utility model purpose provides a kind of curtain wall with steel aluminium combination fire prevention section bar, and as curtain wall main body frame supporting construction, to improve fireproof performance, the mechanical property of curtain wall, it is convenient, specious to implement simultaneously.
The utility model purpose realizes through following technical scheme:
The utility model curtain wall is with steel aluminium combination fire prevention section bar; Connected to form at its beginning interface by the indoor outside a pair of ∏ shape section bar pair, the skin of this indoor outside section bar is an aluminium extruded sections, and internal layer is a steel profile; The internal layer steel profile of the secondary beginning interface of ∏ shape section bar has inside sealing mat groove and outside flange respectively in the indoor; Inside groove cooperates with sealing mat, and outside flange both sides form face glass notch is installed, and flange end has installing hole; The internal layer steel profile of the secondary beginning interface of ∏ shape section bar has inside sealing mat groove to cooperate with sealing mat in the outside; Beginning interface indoor outside ∏ shape section bar is secondary through tapping screw is fastenedly connected, and the cladding glass panel promptly is securely held in the face glass notch.
The length of above-mentioned outward flange and face glass consistency of thickness.
The design's curtain wall is with steel aluminium combination fire prevention section bar, and skin is an aluminium extruded sections, so its exterior decorative effect is good; Internal layer is a clod wash galvanized steel section bar, so its holding capacity and fire resistance are good; Between the secondary beginning interface of indoor outside ∏ shape section bar, sealing mat is arranged, not only make the secondary good sealing effect of section bar avoid corrosion, and the clamping firm, stable of face glass, construction and installation are convenient.
Description of drawings
Fig. 1 is the utility model profile structure sketch map.
Fig. 2 is that the utility model section bar laterally connects the construction sketch map.
Fig. 3 is that the utility model section bar vertically connects the construction sketch map.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further specify the utility model.
The design's curtain wall is with steel aluminium combination fire prevention section bar; Form the section bar auxiliary connection by indoor ∏ shape section bar N and outside ∏ shape section bar W butt joint; Wherein indoor ∏ shape section bar is made up of with internal layer steel profile 2 outer aluminium extruded sections 1, and its outer aluminium extruded sections 1 is by outer aluminium extruded sections 11 and interior aluminium alloy extrusions 12 mutual snappings, and its internal layer steel profile 2 is provided with inside sealing mat groove 2a and cooperates with sealing mat 5 right shapes in ∏ shape section bar beginning interface both sides; There is outside flange 2b the centre; Form face glass in the both sides of this flange 2b notch C is installed, the length of flange 2b depends on the face glass thickness of engineering design, with the face glass consistency of thickness; Outside ∏ shape section bar is made up of with internal layer steel profile 4 outer aluminium extruded sections 3, and its internal layer steel profile 4 is provided with inside sealing mat groove 4a and cooperates with sealing mat 5 right shapes in ∏ shape section bar beginning interface both sides.
During construction; The face glass that face glass 6 places the both sides of flange 2b to form is installed notch C; Between face glass 6 bottoms and flange 2a, be lined with rubber cushion blocks 7 during vertical the installation; Tapping screw 8 is drilled in the respective apertures K that flange 2b holds successfully in advance, indoor outside ∏ shape section bar N, W two parts is connected fastening, and the cladding glass panel promptly is securely held on the utility model curtain wall and prevents fires in the face glass notch of section bar with the combination of steel aluminium.
Claims (2)
1. curtain wall is with steel aluminium combination fire prevention section bar; Connected to form at its beginning interface by the indoor outside a pair of ∏ shape section bar pair, the skin that it is characterized in that indoor outside section bar is an aluminium extruded sections, and internal layer is a steel profile; The internal layer steel profile of the secondary beginning interface of ∏ shape section bar has inside sealing mat groove and outside flange respectively in the indoor; Inside groove cooperates with sealing mat, and outside flange both sides form face glass notch is installed, and flange end has installing hole; The internal layer steel profile of the secondary beginning interface of ∏ shape section bar has inside sealing mat groove to cooperate with sealing mat in the outside; Beginning interface indoor outside ∏ shape section bar is secondary through tapping screw is fastenedly connected, and the cladding glass panel promptly is securely held in the face glass notch.
