Description
Technical field
The utility model relates to bridge construction field, specifically a kind of Truss Steel case beam of drag-line bridge.
Background technology
Along with the continuous lifting of economic level, the transport development cause of China has obtained the achievement attracting people's attention, and has obtained especially develop rapidly as the bridge of road important component part.In current bridge construction, extensively adopted have that strong, the antitorque demeanour of bending resistance is large, supporting capacity is strong, simple in structure, be easy to the steel case beam manufactured.But existing steel case beam (comprising the parts such as top board, base plate and web) adopts the manufacture of entity Plate Welding to form conventionally, shortcomings such as (steel plate consume more) that existence deadweight is excessive and manufacturing cost is too high, need further improvement.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of Truss Steel case beam is provided, and this steel case beam should have that deadweight is light, manufacturing cost is lower, simple in structure and robust feature.
The technical solution of the utility model is: a kind of Truss Steel case beam, is characterized in that: described steel case beam comprises that cross section is the housing of trapezoidal shape and the trussed construction that is arranged in enclosure interior; Described trussed construction comprises and is somely the perpendicular boom of rectangular vertical layout and is fixed on two sprit bars between adjacent perpendicular boom.
Described housing comprises the upper plate and the lower shoe that are arranged in parallel up and down, be fixed on the left plate between edge, upper plate left side and edge, lower shoe left side and be fixed on upper plate right edge along and lower shoe right edge edge between right plate.
Described perpendicular boom is arranged between upper plate and lower shoe and upper plate and lower shoe are fixed respectively at two ends.
The two ends of described sprit bar are fixed with bottom and the top of two perpendicular booms respectively.
The beneficial effects of the utility model are:
Inside of the present utility model is trussed construction, not only reduce steel plate use amount, significantly reduce deadweight, effectively control manufacturing cost, but also good stress performance and the anti-fatigue performances such as high bearing capacity, high rigidity, high anti-twisting property are ensured, reached the application load bearing requirements of steel case beam, can more reasonably be distributed in the stressing conditions in longspan structure application, therefore the utility model is the steel case beam that a kind of performance is very good and structure is very good.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of Truss Steel case beam, comprises housing and trussed construction; The cross section of described housing is trapezoidal shape and identical with right plate structure by upper plate 1, lower shoe 2 and two side plate 3(left plates) enclose and form, shell length is determined as required; Wherein, upper plate and lower shoe are arranged in parallel up and down, the width of upper plate is greater than the width of lower shoe, two side plate wherein sides that oblique cloth postpone connects respectively upper plate and lower shoe are along (both sides of left plate are fixed with the edge, left side of upper plate and the edge, left side of lower shoe respectively, and the both sides of right plate are fixing with the right edge edge of upper plate and the right edge edge of lower shoe respectively).
Described trussed construction is arranged in enclosure interior, comprises some perpendicular booms 4 and some sprit bars 5; Described perpendicular boom is vertically arranged between upper plate and lower shoe in a matrix form, can housing be supported in the vertical direction; As shown in Figure 3, the arrangement mode of described perpendicular boom is that 9 row (horizontal direction of Fig. 3) * 5 are listed as, and can change according to actual service condition quantity and the arrangement of perpendicular boom.
Described sprit bar is arranged in (two adjacent perpendicular booms on row matrix or column direction) between two adjacent perpendicular booms, can support housing in the other direction; One end of described sprit bar and the bottom of one of them perpendicular boom are fixed, and the top of the other end and another perpendicular boom is fixed, and between described sprit bar, indention is arranged (as shown in Figure 2 and Figure 4); The quantity of described sprit bar is determined according to the quantity of perpendicular boom.
Between each parts of the present utility model, can form an entirety by welding, riveted joint or screw fastening structure; Wherein, perpendicular boom, sprit bar can adopt shaped steel (as angle bar, angle steel, square steel) or seamless steel pipe to make, and upper plate, lower shoe and side plate can adopt steel plate to make.
Claims (2)
1. a Truss Steel case beam, is characterized in that: described steel case beam comprises that cross section is the housing of trapezoidal shape and the trussed construction that is arranged in enclosure interior; Described trussed construction comprises and is somely the perpendicular boom (4) of rectangular vertical layout and is fixed on two sprit bars (5) between adjacent perpendicular boom;
Described housing comprises the upper plate (1) and the lower shoe (2) that are arranged in parallel up and down, be fixed on the left plate between edge, upper plate left side and edge, lower shoe left side and be fixed on upper plate right edge along and lower shoe right edge edge between right plate;
Described perpendicular boom is arranged between upper plate and lower shoe and upper plate and lower shoe are fixed respectively at two ends.
