Construction supporting device suitable for low space under variable cross-section beam

Abstract

The invention discloses a construction supporting device suitable for a low space under a variable cross-section beam. The device comprises a plurality of supporting units arranged in parallel and a plurality of bases. Each supporting unit comprises an upper chord member, a lower chord member, an adjustable vertical rod and an inclined strut; the lower chord member comprises a horizontal supporting rod, two end supporting rods and a plurality of middle supporting rods; the adjustable vertical rod comprises an outer sleeve, an inner supporting rod and a bolt. The upper chord member comprises a left end rod, at least one middle rod and a right end rod which are sequentially connected through threads; and a base is connected below the horizontal supporting rods at the same position on all the supporting units. The device has the advantages that during building, the height can be freely adjusted according to the specific condition of a low space during bridge construction; the supporting angle can be adjusted through the adjustable vertical rods so as to adapt to construction of bridges of different structures; the positions of the supporting units are finely adjusted through the threads. The device has the advantages of being high in adaptability, convenient to mount and dismount, capable of quickly positioning the supporting node position and fine-tuning the supporting position.

Description

technical field [0001] The invention belongs to the technical field of bridge construction auxiliary equipment, and particularly relates to a construction support device suitable for a low space under a variable-section beam. Background technique [0002] Due to the complexity of the bridge support force, the support device has problems such as inconvenient erection and disassembly during construction. During the construction of bridge structure, the buckle bracket is often used as a supporting device, but the minimum height of the buckle bracket is 550mm, but there is often a low space when setting the support system. In order to put down the height of the buckle bracket, it is generally lower than 550mm. When the space between the Bailey beam and the bottom of the beam is a low space, it will cause the problem that the buckle bracket cannot be put in and the use of other steel or square wood will cause material waste. Therefore, a bridge construction support device is req...

AI Technical Summary

Problems solved by technology

When the space between the Bailey beam and the beam bottom is low, it will cause the buckle support to be put in, and the use of other steel or square wood will cause material waste. Therefore, a bridge construction support device is needed to fill this vacant position.
