Exposed frame glass curtain wall with steel joist frame

Abstract

The invention relates to an exposed frame glass curtain wall with a steel joist frame, which overcomes the defects such as poorer surface spraying effect of common steel profile, difficulty in installing inserting cores of a horizontal steel frame and a vertical steel frame of the frame, material waste and the like in the prior art. The exposed frame glass curtain wall with the steel joist frame comprises the steel joist frame, a glass plane material and a connecting assembly for clamping and fixing the glass plane material on the steel joist frame and has the technical key points that the horizontal steel frame and the vertical steel frame in the steel joist frame are made of rectangular steel profile rolled by steel plates and are spliced through an inserting core of the horizontal steel frame, the inserting core of the horizontal steel frame is made of U-shaped steel profile with two vertical surfaces and a bottom surface, which is rolled by the steel plates, an upper vertical steel frame and a lower vertical steel frame which are adjacent vertically are spliced by using the inserting core of the vertical steel frame, and the inserting core of the vertical steel frame is made of rectangular steel profile rolled by using the steel plates. The exposed frame glass curtain wall with the steel joist frame is reasonable in structural design and convenient and rapid to install, ensures the installing precision of the horizontal steel frame and the vertical steel frame of the curtain wall, is beneficial to the release of stress generated by expansion caused by heat and contraction caused by cold, is safe and reliable in use, reduces material and installing costs, and further improves the sealing property and the decoration effect of the curtain wall.

Description

technical field [0001] The invention relates to a building curtain wall used for building exterior decoration and protection, in particular to a steel keel frame exposed frame glass curtain wall suitable for large span and large division requirements. Background technique [0002] Most of the existing steel keel frame exposed frame glass curtain walls use commonly used steel profiles as the keel. This kind of steel keel frame is limited by production technology, spraying processing technology and other conditions, and inevitably has the following defects: the spraying effect on the surface of the steel keel frame is poor; the fillet of the steel keel frame is too large, and the straightness is not good; the cross-section deviation Large size makes installation difficult; there are no anti-corrosion measures on the inner surface, causing rust water to flow down; the cross-sectional specification is single, and the thickness is often too large due to size restrictions, which w...

Problems solved by technology

[0006] The object of the present invention is to provide a steel keel frame exposed frame glass curtain wall, which overcomes the defects in the prior art such as poor surface spraying effect of commonly used steel profiles, difficulty in installing frame steel bars, mullion inserts, and waste of materials. The structural design is reasonable, the installation is light and fast, and the installation accuracy of the steel horizontal and vertical frames of the curtain wall is ensured, which is conducive to releasing the stress caused by thermal expansion and contraction. It is safe and reliable to use, reduces material costs and installation costs, and further improves the sealing performance and decoration of the curtain wall. Effect
