Formwork supporting system of large-span high-altitude cantilever structure

Abstract

The invention discloses a formwork supporting system of a large-span high-altitude cantilever structure, and relates to the technical field of building construction. The formwork supporting system comprises a working layer floor slab, a plurality of U-shaped bolts are fixed to the working layer floor slab, a cantilever beam is arranged among spines of the U-shaped bolts, pressing plates are installed on the spines of the U-shaped bolts in a sleeving mode, and nuts are screwed on the spines of the U-shaped bolts; the two ends of a steel wire rope are fixed to the right end of the cantilever beam and the upper end of a working layer supporting column correspondingly, and a supporting rod is fixed to the right sides of lower-layer supporting columns through split bolts; and the upper ends ofinclined supporting rods are hinged to the positions below the cantilever part of the cantilever beam, the lower ends of the inclined supporting rods are sequentially located on the cantilever parts of lower-layer floor slabs, a supporting frame is fixed to the position above the cantilever beam, and formworks are fixed to the positions above the supporting frame. The formwork supporting system issuitable for being applied to construction of a high-altitude cantilever balcony, stable support can be provided for the formworks, the structure is simple and stable, construction is safe and rapid,repeated utilization can be achieved, and the cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork support system of a large-span high-altitude cantilever structure. Background technique [0002] With the gradual rise of tourist real estate and characteristic towns, the viewing balcony structure in buildings has been favored and widely used in tourist buildings. The viewing balcony is a unique space. In order to achieve its wonderful visual effect, the span of the balcony is increased; however, the formwork support during the construction process becomes more and more difficult, and the cast-in-place concrete structure is prone to tilt or deflection. In traditional construction, due to the limited extension length of the I-beam, the method of erecting and landing is generally used when the span is increased. However, this method is not suitable for the construction of high-altitude cantilevered balconies, and the cost is high, which is no longer satisfactor...

Problems solved by technology

The viewing balcony is a unique space, in order to achieve its wonderful visual effect, the span of the balcony is increased; however, the formwork support during the construction process is becoming more and more difficult, and the construction of cast-in-place concrete structures is prone to inclination or downward deflection

In traditional construction, due to the limited protruding length of the I-beam, the method of erecting and landing is generally used when the span increases. However, this method is not suitable for the construction of high-altitude cantilevered balconies, and the cost is high, which is no longer satisfactory for emerging industries. construction needs
