Abstract
The utility model provides a narrow, tall, long and large box type structural beam, which comprises an upper cover plate (1), web plates (2), a structural beam inner cavity partition board (3) and a lower cover plate (4). A plurality of technical brace rods (6) mounted in the inner cavity of the structural beam are connected with each web plate (2) via a fixing method of spot welding and are maintained in the inner cavity of the structural beam. By utilizing the technical brace rods, the utility model can prevent the web plates denting or upwarping and guarantee the inner cavity size, web plate parallelism and rigidity in all directions of the structural beam. Besides, the utility model is simple in assembly, thereby greatly reducing mounting cost.
Description
Technical field
The utility model relates to the manufacture method of structural beams, particularly relates to a kind of vertical rectangle box type structure girder.
Background technology
In railway truck industry and construction trade, often run into the narrow and high box type structure girder of growing up, this box type structure girder often is in important carrying position, to all exigent accuracy of manufacture of inner cavity size, side sway, distortion and very strict quality loop, manufacture difficulty is very big.The inner chamber width of this narrow and high box beam two webs of growing up is between 80～500mm, web height is between 300～2000mm, often be not easy to personnel operation, use traditional manufacture method mainly to have following shortcoming: the one, the box-structure web produces bigger wave transformation; The 2nd, box type structure girder produces bigger side sway or distortion; The 3rd, powerful assembling in manufacturing process makes box type structure girder have very big unrelieved stress.These shortcomings will make the box type structure girder that utilizes the traditional handicraft manufacturing be difficult to reach the technical requirements and the quality loop of regulation.
Summary of the invention
Technical problem to be solved in the utility model is: for overcoming the defective that prior art exists, provide a kind of narrow and high box type structure girder of growing up.
The utility model solves its technical matters and adopts following technical scheme:
Narrow and the high box type structure girder of growing up that the utility model provides, its structure is: comprise upper cover plate, web, structural beams inner chamber dividing plate and lower cover.Wherein: in the inner chamber of described structural beams, a plurality of process support rods are housed, these process support rods connect each web by the spot welding fixed form, and stay in the inner chamber of structural beams.
The structural beams that the utility model provides compared with prior art has following major advantage:
One. result of use is obvious: owing to adopted the process support rods with suitable rigidity, and make it to captive joint with the web in the structural beams inner chamber by even assembling spot welding mode, the web that therefore can prevent structural beams stays or arches up, guarantee the inner cavity size and the web parallelism of structural beams, and increase structural beams respectively to rigidity.
They are two years old. and process support rods is simple in structure, and is in light weight, easy to make.
They are three years old. and easy for installation: as not need complicated frock, can reduce cost of installation greatly.

The specific embodiment
Narrow and the high box type structure girder of growing up that the utility model provides, its structure is: comprise upper cover plate 1, web 2, structural beams inner chamber dividing plate 3 and lower cover 4.In the inner chamber of described structural beams, a plurality of process support rods are housed, these process support rods connect each web by the spot welding fixed form, and stay in the inner chamber of structural beams.
Described process support rods can be section bar or the sheet material spare of a kind of transversal surface for circular, annular, square or L shaped structure.This strut can adopt machining mode to make.
The inner chamber width of the described box type structure girder of growing up is 80～500mm.
The height of described web 2 is 300～2000mm.
Below in conjunction with accompanying drawing, and the utility model is described in further detail to be fabricated to example with outlet flatcar curb girder, but do not limit the utility model.
As depicted in figs. 1 and 2: Madagascar flatcar curb girder length overall 12560mm is formed by 1 upper cover plate 1, two 2,16 inner chamber dividing plates 3 of web and 1 lower cover 4 assembly welding and to form two web inner cavity sizes, 120 ± 1mm.The curb girder manufacturing technology requires: web 2 wave transformations are not more than 3mm/m, and the curb girder side sway is not more than 3mm/m.
According to the structure of above-mentioned curb girder, select suitable process support rods 6, the process support rods structure is outside dimension φ 45mm, the pipe of wall thickness 7mm, material is Q235A.Circular tube structure as shown in Figure 4 and Figure 5.
According to the position and the structure of inner chamber dividing plate 3, determine the installation site that process support rods 6 is suitable, its installation site is as shown in Figure 3.
Can export the flatcar curb girder by following step assembling:
A. the side of inner chamber dividing plate 3 is fixed in the spot welding mode with two web 2 inner planes respectively; Adopt a plurality of well-distributed process support rods 6, described web is strutted, and fix in the spot welding mode; After described process support rods 6 welding finish, stay in the inner chamber of structural beams, no longer take out;
B. the space that stays for 2 postweldings of inner chamber dividing plate 3 and web is connected with welding manner; On the longitudinal direction of described curb girder, be symmetrically welded to two ends simultaneously, adopt multi-pass welding to connect according to the leg size by the centre;
C. upper cover plate 1 is rested the upper end of described web and inner chamber dividing plate, and their are connected and be fixed together in the spot welding mode;
D. with lower cover 4 in the spot welding mode, its lower end with described web and inner chamber dividing plate linked to each other and be fixed together;
E. after the spot welding steady job of completing steps c and d, simultaneously on the longitudinal direction of described curb girder, be symmetrically welded the weld seam 5 and the lower cover of upper cover plate 1 and web to two ends, adopt multi-pass welding to connect according to the leg size by the centre;
F. on the longitudinal direction of described curb girder, be symmetrically welded the weld seam 5 and the lower cover 4 of lower cover 4 and web by the centre to two ends, adopt multi-pass welding to connect according to the leg size.
The utility model is asked for an interview table 1 with the performance ratio of tradition outlet flatcar curb girder.
