Light combined hanging box with recyclable baseplate steels and construction technology thereof

Abstract

The invention discloses a light combined hanging box with recyclable baseplate steels. The light combined hanging box comprises a baseplate, four wall bodies, an outrigger, and lateral stable support beams which are connected between the outrigger and the wall bodies; wherein the four wall bodies are connected by a support frame; a lifting lug is arranged at the upper end face of outrigger; a jack placing beam is arranged under the outrigger; the outrigger is connected with the baseplate by a supporting column; a jack is arranged between the outrigger and the jack placing beam; the lower end of the jack placing beam is connected with the top end of a steel casing. The light combined hanging box has the following advantages: 1, the bearing abilities of bamboo plywood and bottom sealing concrete are fully used under a condition that a poor sea state of open seas is overcome, the turning of the baseplate steels is effectively realized, and the steel consumption is greatly reduced; 2, the structure is light; for the hanging box of the same specification, the lifting weight of the combined baseplate hanging box is similar to the self weight of a traditional steel baseplate hanging box, so that relative to the concrete prefabricated baseplate steel hanging box, the rated load weight and the lifting difficulty of a floating crane are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of hanging boxes, in particular to a light composite hanging box with recyclable base steel and a construction process thereof. Background technique [0002] Due to the influence of sea tides, wind waves and typhoons, at present, the suspension box structure of two types of materials is used for the construction of the suspension box cap of the sea approach bridge of the cross-sea bridge: [0003] One is to use a steel floor hanging box. The wall structure and floor structure of the hanging box are all steel structures. The steel floor uses steel plates as panels, and is equipped with longitudinal beams and beams for strengthening the panels. The longitudinal beams and beams are shaped steel The component is characterized by light weight and small rated load for hoisting. [0004] The second is the concrete prefabricated floor steel hanging box. In this type of hanging box, the wall structure that can be tu...

AI Technical Summary

Problems solved by technology

[0005] For the all-steel structure suspension box, because the bottom plate is made of steel structure, the steel bottom plate and the concrete are firmly bonded together after the cap is poured, and the bottom plate is difficult to disassemble. The dismantling efficiency is low, the price is high, and the disassembled floor can no longer be reused; for the concrete prefabricated floor steel hanging box, although the amount of steel can be greatly reduced, the concrete floor needs formwork maintenance, and the reinforced concrete floor is self-heavy. Significantly increases the self-weight of the hanging box, so larger hoisting equipment is required to complete the hoisting operation, thus increasing the rated lifting capacity of the hoisting equipment and the difficulty of hoisting, even if the bottom plate is divided into several parts and assembled in blocks to reduce the hoisting weight , also increased the construction period and labor costs
