Abstract
The utility model relates to a rectangular wedge-shaped cushion block for incremental launching construction of a large-span steel structure bridge. The rectangular wedge-shaped cushion block comprises a steel frame a double-layer steel bar net sheet, a concrete reinforcing layer and a hanging ring. The concrete wedge-shaped cushion block is provided with a rectangular steel frame, the double-layer steel bar net sheet laid in the steel frame is fixedly welded to the steel frame, the smooth concrete reinforcing layer is further poured in the steel frame, and the thickness of the concrete reinforcing layer equals the depth of the steel frame. The hanging ring is fixedly connected to one lateral face of the steel frame. The rectangular cushion block is simple to manufacture, can be manufactured into different thicknesses to meet the construction requirement, is convenient and flexible to use and can be repeatedly utilized, so that engineering cost is greatly reduced.
Description
Technical field
The utility model relates to the realm of building construction, is specifically related to a kind of greatly across steel structural bridge incremental launching construction concrete rectangular cushion block.
Background technology
Existingly across steel structural bridge incremental launching construction, all must support pontic with many root posts greatly, vertical load when these columns should bear pontic weight, construction, also will bear transverse load.If which side face supporting capacity deficiency all can cause accident to occur.Between column and equipment, between equipment and pontic, need to have cushion block adjustment height, prior art all adopts steel cushion block, the steel plate of a large amount of different-thickness is just difficult to do his use after being tailored into cushion block again, wastes very large.
Utility model content
In order to address the above problem, the utility model proposes a kind ofly greatly across steel structural bridge incremental launching construction concrete rectangular cushion block, it makes simple, can be made into the cushion block of various different-thickness to meet construction demand, flexible and convenient to use, and can reuse, engineering cost is reduced greatly.
The utility model solves the technical scheme that its technical problem adopts: a kind of greatly across steel structural bridge incremental launching construction concrete rectangular cushion block, comprise steel framework, double steel bar net sheet, concrete strengthening layer and suspension ring; Described concrete rectangular cushion block has a rectangle steel framework, is equipped with double steel bar net sheet in described steel framework, and described double steel bar net sheet and steel framework are welded and fixed; In described steel framework, also build smooth concrete strengthening layer, the thickness of described concrete strengthening layer and the deep equality of steel framework; One side of described steel framework is fixedly connected with suspension ring.
Described concrete rectangular cushion block is of a size of: long 700-900 millimeter, and wide 500-700 millimeter, thick 80-300 millimeter, cushion block is smooth.
Described steel framework is formed by 1-2 millimeters thick Plate Welding, and with surrounding frame and base plate, its bottom surface is smooth, has enough strength and stiffness.
Described double steel bar net sheet is by crisscross being welded of III grade reinforcing steel of 10 millimeters of diameters, and rebar spacing is 100 millimeters, and thickness of protection tier is 15 millimeters.
Described concrete strengthening layer is to build and form with common C40 pea gravel concreten, has not allowed any crackle.
Described suspension ring are bent and are formed by the reinforcing bar of diameter 20-25 millimeter, and reinforcing bar gos deep into anchoring in concrete pad, is used for cushion block to lift installation.
The beneficial effects of the utility model are: a kind of greatly across steel structural bridge incremental launching construction concrete rectangular cushion block, it makes simple, can be made into the cushion block of various different-thickness to meet construction demand, flexible and convenient to use, and can reuse, engineering cost is reduced greatly.
