Combined Bailey frame load-bearing bent frame for pouring long-span concrete beams

Abstract

Disclosed is a combined type bailey frame load-bearing shelving used for pouring a large-span concrete beam. The combined type bailey frame load-bearing shelving comprises combined type bailey frame beams, a steel pipe shelving and supporting base systems. The two ends of each of the bailey frame beams are respectively arranged on a steel box beam. The steel box beams are fixed on the two parallel supporting base systems of a concrete erect wall body. A plurality of I-shaped parallel steel bases are arranged on the bailey frame beams. The steel pipe shelving is arranged on the steel bases in a lapping mode. Concrete beam moldboards are arranged on the upper portion of the steel pipe shelving. A plurality of steel corbels fixed on the concrete wall surfaces at two sides are used to support the combined type bailey frame load-bearing shelving. Shortages of a conventional construction method that falling shelving erecting moldboards are set up normally are overcome. The combined type bailey frame load-bearing shelving is large in load-bearing amount and high in safety and stability. Bearing requirements of an upper air beam and construction of plate concrete are guaranteed. The combined type bailey frame load-bearing shelving is convenient and quick to erect and dismantle, and is capable of saving the engineering cost, accelerating a construction schedule and guaranteeing the construction quality. The combined type bailey frame load-bearing shelving is particularly suitable for a working condition of pouring a concrete beam and a plate structure.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a combined Bailey frame load-bearing bending device for pouring large-span concrete beams. Background technique [0002] In the construction of ship lifts in hydropower stations, it is common to encounter cast-in-place concrete beams and slab structures designed on two adjacent concrete vertical walls, such as top beams and platforms of ship lifts (such as figure 1 ), this kind of structural concrete usually has the characteristics of large span, heavy weight, etc., and the height from the ground is also large. It is a big safety hazard, and it is very difficult to set up and dismantle the bent racks. At the same time, it needs to consume a lot of materials, resulting in high cost investment, slow construction progress, and difficulty in ensuring construction quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
