Supporting steel frame of high altitude large-span cantilever structure mold frame

Abstract

The invention discloses a supporting steel frame of a high altitude large-span cantilever structure mold frame. The supporting steel frame comprises a floor slab, a supporting frame and a cantilever beam, wherein the supporting frame is of triangular shape; the lower end of the triangular supporting frame is mounted on an embedded iron piece on a lower floor slab; the upper end of the triangular supporting frame is provided with the cantilever beam; and one end of the cantilever beam penetrates in an anchoring ring mounted on an upper floor slab and is wedged through a wooden wedge. The supporting steel frame of the high altitude large-span cantilever structure mold frame, disclosed by the invention, has the advantages of reasonable stress, high rigidity, strong bearing force at the cantilever end, large cantilever span, strong bearing force, large rigidity of the frame body and capability of effectively ensuring the integral stability and construction safety of the large-span cantilever structure mold frame. The steel frame can be integrally spliced on the site in advance and has the advantages of lightweight frame body, convenience for mounting and detaching and labor and time conservation. The supporting steel frame can be recycled for multiple times, obtains better economic benefits and is worthy of being generalized.

Description

technical field [0001] The invention belongs to the field of cantilevered supporting steel frames and relates to the field of building construction, in particular to a supporting steel frame used for high-altitude and large-span cantilevered structure formwork. . Background technique [0002] With the continuous development of construction technology, architects are paying more and more attention to the appearance of buildings, usually using high-altitude, long-span, and super-long cantilever structures to achieve a magnificent and solemn modeling effect. The traditional I-beam cantilever is adopted, the span of the steel beam is small, and the bearing capacity of the cantilever end is weak, which cannot meet the requirements of the formwork for carrying a large-span cantilevered structure; while the floor-type scaffolding is used for support, it is necessary to erect a structure Complicated tall frames are labor-intensive, material-intensive, and time-consuming, and are ne...
