Building floor corner cantilever outer frame supporting system

Abstract

The invention discloses a building floor corner cantilever outer frame supporting system. The building floor corner cantilever outer frame supporting system comprises column side platform beams, corner platform beams, platform beam base plates, countersunk head anchor bolts, connecting bolts, connecting plates, supporting rod sleeves, adjustable supporting rod sleeves, pins, supporting rod base plates, vertical rod bases, vertical rods, short transverse rods, corner lap beams, platform pedals, corner arc-shaped transverse rods and long transverse rods. According to the building floor corner cantilever outer frame supporting system, a cantilever external scaffold replaces a traditional floor type scaffold, the cost is reduced, and the safety coefficient is increased; and a triangular supporting system with an adjustable bevel edge is adopted at the corner of an outer frame, H-shaped steel beams do not need to penetrate into a building floor to be anchored and are borne through the triangular supporting frame, the problem that the outer frame is difficult to arrange at the corner is solved, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a support system for a corner cantilevered outer frame of a building floor. Background technique [0002] With the development of my country's construction industry, the height of buildings is getting higher and higher, and there are more and more floors, especially for commercial and residential buildings. Due to the reduction of construction land and the increase of investment and development costs, high-rise and super high-rise buildings have become common. In building construction, according to the construction process and the safety needs of engineering operations, during the construction of the building, it is necessary to set up an outer frame to protect the safety of the operation and carry out the construction of the outer protection. In the construction of high-rise buildings, the height of the building is relatively high. If a floor-standing external scaf...

AI Technical Summary

Problems solved by technology

[0003] 1. The cost of floor-standing external scaffolding is high, and the higher the building, the more materials and labor used;

[0004] 2. As the height of the floor-to-ceiling external scaffolding continues to increase, its stability coefficient continues to decrease, and there are potential safety hazards;

[0006] 1. At the sun corner of the floor, large cross-section columns block the layout of the I-beams, resulting in insufficient support points for the outer frame at the sun corner, which cannot meet the force requirements of the base of the outer frame;

[0007] 2. At the external corner, if it is a small cross-section column, I-shaped steel beams are supported on both sides of the column. easy to handle;

[0008] 3. The horizontal bar of the outer frame at the positive corner meets, which needs to be dislocated, which is not convenient for erection. At the same time, the space of this part is small, which is not conducive to the passage of long objects;

[0009] 4. If the I-beam supported by the outer frame passes through the interior of the column, it will cause the reinforcement displacement of the column and affect its bearing capacity. At the same time, it is not easy to dismantle it. If the I-beam is cut off at the end of the construction, it will cause waste of materials and labor ;

[0010] Some methods use a triangular fixed support frame, the length of the hypotenuse is fixed and cannot be adjusted, and it is difficult to fix when encountering a concave-convex facade or a misplaced facade
