Steel cable guide mechanism and building curtain wall fixing device consisting of steel cable guide mechanism

Abstract

The invention discloses a steel cable guide mechanism and a building curtain wall fixing device consisting of the steel cable guide mechanism. The steel cable guide mechanism comprises a fixed seat with open slots, and guide wheels which are arranged in the open slots, wherein the guide wheels are rotatably connected with the fixed seat and the number of the guide wheels is one or two. The building curtain wall fixing device comprises a steel cable with two ends which are fixedly arranged on a structural member main body, and the steel cable guide mechanism which is used for positioning the steel cable, wherein the steel cable guide mechanism is fixedly arranged on the structural member main body. The steel cable guide mechanism provided by the invention is used for a vertical steel cable. When external force is applied to the vertical steel cable, pressure is applied to the guide wheel on any side and the vertical steel cable moves up and down, the guide wheel can rotate; and when the external force disappears, the guide wheel rebounds to the original position. Therefore, the friction of the steel cable at a bearing point becomes rolling friction; if sector-shaped wheels are used, the contact area between the steel cable and the guide wheels can be increased within a limited structural space and the stress state of the steel cable can be improved; and since the guide wheels are made of a material such as aluminum, copper or engineering plastic which is softer than the material of the steel cable, the wear of the steel cable can be reduced as much as possible.

Description

technical field [0001] The invention relates to a mechanism for guiding the cables (that is, steel cables) of a building curtain wall, which can well deal with the connection problem between the steel cables and the main structure. It plays a good role in guiding and positioning and can eliminate the force influence between the steel cable and the main structure (that is, the main body of the structural part) (that is, the up and down deformation of the main structure does not affect the steel cable, and the up and down sliding of the steel cable does not affect the main structure. ). Background technique [0002] In the prior art, when dealing with the intersecting joints between the steel cables and the main structure, they are directly fixed on the main structure by clamps. In this way, it is easy to damage the steel cables at the connection part between the steel cables and the clamps, or to disconnect the steel cables up and down. , respectively fixed on the upper and ...

Problems solved by technology

[0002] In the prior art, when dealing with the intersecting joints between the steel cables and the main structure, they are directly fixed on the main structure by clamps. In this way, it is easy to damage the steel cables at the connection part between the steel cables and the clamps, or to disconnect the steel cables up and down. , which are respectively fixed on the upper and lower parts of the main structure at the intersection joints, so that the steel cables cannot adapt to the deformation of the main structure, and the main structure is also easily affected by the steel cables

[0003] Due to the cable-type fixing of glass and other curtain walls, the diameter of the steel cable is relatively large (the steel cable needs to generate tens to hundreds of tons of pre-tightening tension to produce a certain rigidity), when guiding or fixing it, The mechanism used needs to take up a lot of space, and when the steel cable passes through the main structure, it should also be considered that the reserved aperture on the main structure should not be too large, otherwise the strength of the main structure will be reduced
