Problems solved by technology

[0002] The invention is mainly used for large-scale crawler cranes to enter the construction project above the concrete floor. The traditional large-scale crawler cranes directly go up the concrete floor. The concrete floor needs to be reinforced according to the calculation and analysis of the construction conditions. Measures are also needed to prevent the crawler from affecting the concrete floor. Destruction of the floor surface (sandstone or rubber mat), many procedures and a large amount of measures

Abstract

The invention relates to a concrete floor walking trestle device for a large crawler crane and a mounting method of the concrete floor walking trestle device. The device comprises a finished roadbed box, a trestle beam, a transfer beam, an embedded part, temporary stacking plates and a connecting beam. The lower portion of the transfer beam is connected with the connecting beam and arranged on theembedded part through the connecting beam, the lower portion of the trestle beam is connected with the connecting beam and arranged on the transfer beam through the connecting beam, the finished roadbed box is laid on the upper portion of the trestle beam, and temporary stacking plates are arranged between the transfer beam and the embedded part, between the transfer beam and the trestle beam andbetween the trestle beam and the finished roadbed box. Mechanical and construction loads are transmitted to the next layer of concrete column through structural steel, the structure is simple, the safety performance is high, turnover use can be achieved, and green construction is facilitated.

Description

technical field [0001] The invention relates to the field of hoisting construction measures, in particular to a walking trestle device for hoisting a large crawler on a concrete floor slab and an installation method thereof. Background technique [0002] The invention is mainly used for large-scale crawler cranes to enter the construction project above the concrete floor. The traditional large-scale crawler cranes directly go up the concrete floor. The concrete floor needs to be reinforced according to the calculation and analysis of the construction conditions. Measures are also needed to prevent the crawler from affecting the concrete floor. The surface of the floor is damaged (sandstone or rubber mat), with many procedures and a large amount of measures. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides a walking trestle device and its installation method for large-scale crawler cranes on concrete floors...
