Large caterpillar crane floor board roadbed box

Abstract

The invention discloses a large caterpillar crane floor board roadbed box which comprises a cross beam. Vertical beams are installed on the lower surface of the cross beam and are in threaded connection with the cross beam. The number of the vertical beams is two. The two vertical beams are arranged close to the two ends of the cross beam. H-shaped steel beams are installed on the inner sides of the two vertical beams and on the lower surface of the cross beam. The tops of the H-shaped steel beams penetrate the cross beam and are connected with the cross beam through steel hoops. The bottom of each H-shaped steel beam and the bottom of the corresponding vertical beam are located on a bottom board. A box body is installed between the two bottom boards. The top of the box body is arranged on the lower surface of the cross beam. One or more frameworks are vertically installed between the box body and the cross beam. The box body is of an inverted-U-shaped structure, and an opening of the box body is transversely connected with a caterpillar band. By the adoption of the large caterpillar crane floor board roadbed box, the construction efficiency can be improved to a certain degree, the construction convenience is enhanced, the structural strength of the box is high, damage is not likely to be generated, connection is tight, conveyance is convenient, the influences on construction activities are small, the floor reinforcing cost is low, and safety is quite high.

Description

Technical field [0001] The invention relates to a subgrade box, in particular to a large crawler crane floor subgrade box. Background technique [0002] In many architectural designs, steel structure is adopted. A large number of heavy steel structure components require large crawler cranes for transportation and hoisting. However, due to site restrictions, large crawler cranes need to carry out large-scale steel structure hoisting and walking operations on the concrete floor. As a result, the originally designed reinforced concrete floor cannot meet the requirements of bearing capacity under construction load, and reinforcement measures must be taken. At the same time, when the earthwork is carried out in places with large water content such as soft soil foundations, the underground soil quality is mostly silty soil in flow plastic state and silty clay in flow plastic to soft plastic state. The soil is soft and has low strength. The nature of the project is poor, which brings g...

Problems solved by technology

[0002] In many architectural designs, steel structures are adopted, and a large number of heavy steel structural components require large-scale crawler cranes for transfer and hoisting. However, due to site constraints, large-scale crawler cranes need to carry out large-area steel structure hoisting and walking operations on concrete floors. As a result, the originally designed reinforced concrete floor cannot meet the requirements of the bearing capacity under the construction load, and reinforcement measures must be taken for it

At the same time, when earthwork construction is carried out in places with high soil water content such as soft soil foundations, the underground soil is mostly silty soil in a flow-plastic state and silty clay in a flow-plastic to soft-plastic state. The soil is soft and low in strength. The nature of the project is poor, which brings great inconvenience to the normal excavation construction of machinery
