Truss translation device and truss mounting method

Abstract

The invention discloses a truss translation device and a truss mounting method.The truss translation device comprises a truss main body and supporting frame bodies vertically connected to the two ends of the truss main body, and each supporting frame body comprises a supporting bottom beam, a first supporting column, a second supporting column and walking rollers, the two ends of the supporting bottom beam are fixedly connected with the lower end of the first supporting column and the lower end of the second supporting column respectively, the upper end of the first supporting column and the upper end of the second supporting column are connected in an inverted-V shape, walking idler wheels are arranged at the bottom of the supporting bottom beam, and one or more hoisting points are arranged on the lower side of the truss body, an electric hoist is arranged on each hoisting point. The steel truss translation device is used for splicing the truss bodies one by one from the initial position of the truss bodies according to the sequence formulated by the scheme and then translating the truss bodies to the installation position to be installed in place. According to the invention, the truss can be quickly assembled and translated to a mounting position in a field with relatively small lifting capacity and a narrow construction area, so that the difficulty of in-place mounting of the truss structure is reduced.

Description

Technical field [0001] The present invention relates to the technical field of steel truss construction equipment, and more particularly to a truss translation device and a truss mounting method. Background technique [0002] With the rapid growth of national economic construction, the number of large cross-spatial structures has increased, and the type and form of large spatial structures are very rich, because my country's steel production is greatly improved and the continuous development and utilization of new materials is increasing. Multi-building uses steel truss structures, for example, in public buildings such as large spanners, exhibition halls, gymnasuses and bridges, have a wide range of market prospects and higher additional value for this steel. However, when the steel truss construction is constructed, it is basically after the concrete main structure has been constructed, the steel truss structure in the factory is transported to the construction site, and each st...

AI Technical Summary

Problems solved by technology

For some old city buildings surrounded by residential areas, the construction area is small, the construction area is small, and the conventional hoisting method is not applicable, which makes the installation of the truss structure more difficult. How to protect the concrete roof without structural properties during hoisting and installation Damage and destruction are unavoidable problems. Therefore, it is important to study how to use steel truss translation devices to quickly, efficiently and safely complete the installation tasks of the main truss and secondary beams under the existing environmental conditions of the narrow lifting space.
