Background art:
in the cast-in-place shear wall structure of the conventional assembly type constructional engineering, a scaffold is formed by steel pipes and various buckles for connecting the steel pipes on a construction site during the cast-in-place concrete. The used steel pipe quantity is big, takes a lot of work, takes time, and the unstability phenomenon takes place during the scaffold frame, causes the incident, and assembled wallboard can not install with assembled roof beam, board simultaneously.
The invention content is as follows:
the invention relates to a rectangular steel frame for template installation and component installation of an assembled building cast-in-place shear wall in scaffold engineering in the field of buildings. 1. Rectangular steel frame that there is the bearing diagonal in rectangle steel frame bottom surface center, by rectangular steel frame bottom surface center bearing diagonal multi-angle connecting piece, rectangular steel frame right angle multi-angle connecting piece, the middle angle steel right angle side that has the telescopic joint, the middle steel pipe bearing diagonal that has the telescopic joint, the rectangular steel frame that constitutes the long limit length of adjustable steel support and broadside length. 2. The rectangular steel frame without inclined support in the center of the rectangular steel frame is composed of a rectangular steel frame right-angle connecting piece, an angle steel right-angle side with a telescopic joint in the middle, and a rectangular steel frame capable of adjusting the length of the long side and the length of the wide side of the steel frame. On the construction site, a rectangular steel frame with an inclined support in the center of a rectangular steel frame is installed in one room, a rectangular steel frame without an inclined support in the center of a rectangular steel frame is installed in the other room, the rectangular steel frame and the rectangular steel frame are arranged at intervals, and the rectangular steel frame support is connected through bolts to form a stable rectangular steel frame support for the whole building. The stable rectangular steel frame, the first temporary steel support, the second temporary steel support and the cast-in-place concrete template form the rectangular steel frame support for installing the prefabricated component and the cast-in-place shear wall template of the prefabricated building.
The multi-angle connecting piece of the bottom surface center inclined support of the rectangular steel frame is combined and single, and mainly comprises a connecting piece base, a horizontal angle rotating shaft and a vertical angle rotating shaft;
the rectangular steel frame right-angle multi-angle connecting piece has four schemes: the first scheme mainly comprises a steel ring for adjusting the horizontal angle of the diagonal support of the rectangular steel frame and a ring for adjusting the vertical angle of the diagonal support of the rectangular steel frame.
