Abstract
The utility model relates to a track girder subgrade for a large walking crane. The track girder subgrade comprises a concrete bearing platform, and is characterized in that a concrete track girder is arranged above the concrete bearing platform, wherein wheel rails are placed at the upper end of the concrete track girder; and soft fiber boards are arranged between the concrete bearing platform and the concrete track girder. The track girder subgrade with the structure can achieve more rapid and convenient construction, lower the construction cost and provide conditions for large-area constructions.
Description
Technical field:
The utility model relates to a kind of large-scale stepped type tower crane field, particularly a kind of rail beam roadbed that is used for large-scale stepped type tower crane.
Background technology:
In order to solve the large-scale stepped type tower crane of ZSL55145 (1060t.m) roadbed, as adopt the steel plate subgrade case must special subgrade case, cost on making or leasing is very expensive, adopt the steel plate subgrade case on the other hand, according to construction requirement, steel plate subgrade case total length reaches 1152 meters, does not have so many special subgrade case on the market at all.
Summary of the invention:
The purpose of this utility model is a kind of rail beam roadbed that is used for large-scale stepped type tower crane, can address the above problem.
To achieve these goals, the technical solution of the utility model is as follows: a kind of rail beam roadbed that is used for large-scale stepped type tower crane, comprise the concrete cushion cap, it is characterized in that concrete cushion cap top is provided with the concrete track beam, this concrete track beam upper end is provided with rail, is provided with soft fiberboard between concrete cushion cap and the concrete track beam.
Adopt such structure, make that construction is more convenient, more reduced construction cost, for large-area construction provides condition.
The utility model
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
A kind of rail beam roadbed that is used for large-scale stepped type tower crane comprises concrete cushion cap 1, it is characterized in that concrete cushion cap 1 top is provided with concrete track beam 2, and these concrete track beam 2 upper ends are provided with rail 3, are provided with soft fiberboard 4 between concrete cushion cap 1 and the concrete track beam 2.Rail 3 is as the walking rail of tower crane, soft fiberboard 4 be used between concrete track beam 2 and the concrete cushion cap 1 effective separation and as bed die.
According to an embodiment, be used for ZSL55145 (1060t.m) stepped type tower crane cast-in-situ concrete rail beam ground, the concrete track beam is in place builds, and the planeness of concrete track beam position and rail beam is just controlled by ZSL55145 (1060t.m) stepped type tower crane arrangement requirement and instructions for use.When finding that as rail beam sedimentation exceeds 60mm, the scene can adopt ZSL55145 (1060t.m) stepped type tower crane to adjust, and the every 12m segmentation of concrete track beam is built, deadweight 35t.ZSL55145 (1060t.m) stepped type tower crane is in the 26.5m radius of clean-up, and biggest lifting capacity 40t capable of hoisting satisfies the requirement of lifting capacity.The scene considers because the cast in situs of concrete track beam, soft fiberboard 4 that may adopt and concrete cushion cap 1 fail to isolate fully between reinforcing, therefore on-the-spot special small-sized portal frame, two ends at 12m concrete track beam, utilize the lifting built-in fitting of burying underground in advance as suspension centre, utilize the jack of 50t to carry the empty issuable settlement issues of concrete track beam that solves.
