Mounting structure for unit curtain wall large decorative moulding

Abstract

The invention discloses a mounting structure for a unit curtain wall large decorative moulding. The mounting structure includes a glass curtain wall, a decorative moulding adapter and a vertical decorative moulding assembly; the glass curtain wall includes a vertical column, a cross beam, curtain wall glass, safe edges and an exposed-frame cover plate; a vertical column clamping groove is formed in the vertical column, and a decorative moulding clamping groove is formed in the vertical decorative moulding assembly; the front end of the decorative moulding adapter is matched with the vertical column clamping groove, and the rear end of the decorative moulding adapter is matched with the decorative moulding clamping groove; and the vertical decorative moulding assembly and the exposed-framecover plate are spaced. According to the mounting structure, the lateral wind pressure of the decorative moulding is borne by adapter and clamping groove matched structures, and the decorative moulding does not act on the glass surface any more under the lateral wind pressure, so that the glass is prevented from bearing force locally and then being broken; adhesive strip grooves with the same groove openings can be designed in the adapter and the glass safe edges to ensure that watertight line adhesive strips are connected, and rainwater is prevented from entering the curtain wall through fractures of the adapter; and self-tapping screws mainly play a role in limiting, a bolt assembly only plays a role in retaining, a traditional way of force bearing by threads is changed, and thus safetyperformance is improved.

Description

technical field [0001] The invention relates to an installation structure of large decorative lines of a unit curtain wall, belonging to the technical field of curtain walls. Background technique [0002] There have always been some problems in the application of large decorative lines in the unit curtain wall. The large lines are assembled in the processing plant, and the finished panels take up a lot of space, which makes transportation difficult and directly increases a lot of transportation costs; if installed during construction , if the design node is unreasonable, the installation at heights is difficult, the cost of personnel and measures is high, and the fixed adapter of the line needs to protrude from the main frame of the curtain wall, it is easy to cause the watertight line of the unit curtain wall to be discontinuous. Sometimes rainwater enters the interior of the curtain wall, forming leakage, which seriously affects the function and life of the building. [0...

Problems solved by technology

[0002] There have always been some problems in the application of large decorative lines in the unit curtain wall. The large lines are assembled in the processing plant, and the finished panels take up a lot of space, which makes transportation difficult and directly increases a lot of transportation costs; if installed during construction , if the design node is unreasonable, the installation at heights is difficult, the cost of personnel and measures is high, and the fixed adapter of the line needs to protrude from the main frame of the curtain wall, it is easy to cause the watertight line of the unit curtain wall to be discontinuous. When the rainwater enters the interior of the curtain wall, it will cause leakage, which will seriously affect the function and life of the building.

[0003] At present, the common practice in China is that the root of the aluminum adapter is mainly connected to the column by the screw thread. Under the action of the line's own weight and the lateral wind pressure it bears, the main force on the screw is tensile force and shear force. Once the connection fails, it will cause safety. hidden danger, and under the action of lateral wind pressure on the large decorative lines, the curtain wall surface material glass is directly compressed, which is likely to cause glass breakage; after the unit curtain wall of this structure is installed on site, rubber strips need to be pressed between the lines and the glass, and the process is complicated , which is not conducive to the construction organization of the unit curtain wall
