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.

The specific embodiment

As shown in Fig. 2～6, a kind of large-span concrete beam combined type Bailey bracket bearing bent frame of building, comprise combined type Bailey bracket beam 3, steel pipe framed bent 4, support system 5, at least two combined type Bailey bracket beam 3 two ends that are parallel to each other are seated respectively on the steel case beam 52 of the support system 5 that is fixed on the upright body of wall 1 of concrete that twice are parallel to each other, on combined type Bailey bracket beam 3, evenly, be vertically provided with many i iron bases 6 different in size, to be parallel to each other, on i iron base 6, be erected with steel pipe framed bent 4.

Described support system 5 is comprised of a plurality of load-bearing steel corbels 51 and steel case beam 52, and load-bearing steel corbel 51 is fixedly connected with the many embedded anchor cones 53 that arrange on the upright body of wall 1 of concrete, and steel case beam 52 is erected on the end face of load-bearing steel corbel 51.

Described combined type Bailey bracket beam 3 is to be the compound beam of square or rectangle by the vertical assembled section of a plurality of Bailey brackets.

Many described i iron bases 6 are fixedly connected on the upper chord at combined type Bailey bracket beam 3 tops by many channel-section steel pressing plates 7 and bolt 8, are welded with many reinforcing bar suspension columns 9 on i iron base 6.
