Document Type and Number:
WIPO Patent Application WO/2022/001974
Kind Code:
A1
Abstract:
The present invention relates to the technical field of architectural engineering. Disclosed are a joint ball-based rotating fixation apparatus for an arch truss, and an arch truss mounting system, mainly aiming at reducing a danger coefficient of arch truss mounting construction. The main technical solution of the present invention is a joint ball-based rotating fixation apparatus for an arch truss. The apparatus comprises: a base, a fixing part, and a rotating part. The fixing part comprises a recess body, a first vertical plate, and a second vertical plate; the recess body, the first vertical plate, and the second vertical plate are respectively connected to the base; the opening of the recess body inclines upwardly; the first vertical plate and the second vertical plate are respectively located on opposite sides of the recess body; the first vertical plate is provided with a first through hole, and the second vertical plate is provided with a second through hole, wherein the first though hole and the second through hole are provided opposite to each other. The rotating part comprises a first rod member, a rotating ball, and a second rod member which are sequentially and fixedly connected; the rotating ball is placed in the recess body; the first rod member is rotatably connected to the first through hole, and the second rod member is rotatably connected to the second through hole.
