Abstract
The utility model provides an anti-deformation bridge steel structure which comprises a steel structure body, wherein the steel structure body is made of cylindrical steel, four supporting steel frames are symmetrically arranged in an inner cavity of the steel structure body, the cross sections of the four supporting steel frames are isosceles trapezoid frames, equal waist surfaces of the four supporting steel frames are fixedly contacted with each other, the four supporting steel frames form a steel structure with a square cross section in the steel structure body, and a buffer area is formed between the large end of each of the four supporting steel frames and the inner side wall of the steel structure body; the bridge steel structure is formed by assembling the cylindrical steel structure body and the four supporting steel frames, the using strength of bridge steel is increased, the bending deformation of the whole steel structure is reduced, and the buffer layer is filled between the supporting steel frames and the steel structure body, so that the collision of external impact force on the steel structure is further slowed down, the deformation of the surface of the steel structure body is reduced, and the strength is improved.
Description
Technical Field
The utility model belongs to the technical field of steel structure production, particularly relates to a cylindrical steel structure for a bridge, and particularly relates to an anti-deformation bridge steel structure.
Background
The bridge steel is a steel plate specially used for erecting railway or highway bridges. The bridge steel is divided into rectangular steel and cylindrical steel, the rectangular steel is mostly used for building and bearing bridges, and the cylindrical steel is beautiful and commonly used for surrounding guardrails of bridges.
Most of the cylindrical bridge steel that use in the existing market is a simple cylindricality section of thick bamboo one deck, often can be by vehicle collision deformation and damage, and intensity is poor, and the maintenance cost is high, can only retrieve the guardrail of damage, consequently needs a bridge steel construction of preapring for an unfavorable turn of events shape.
SUMMERY OF THE UTILITY MODEL
In view of the problems of the background art, the present invention provides the following technical solutions:
the utility model provides a bridge steel construction of preapring for an unfavorable turn of events shape, includes steel construction body, steel construction body is the drum steel, four support steelframes, four are installed to steel construction body inner chamber symmetry support steelframe cross-section is isosceles trapezoid frame, four support the equal waists of steelframe all two liang between fixed contact, four the support steelframe is in the steel construction body in the constitution cross-section be the steel construction of square, four support and form the buffer zone between steelframe main aspects and the steel construction body inside wall.
Preferably, the four supporting steel frames and the like waist surfaces are fixed through welding.
Preferably, buffer layers are filled between the large ends of the four supporting steel frames and the inner side wall of the steel structure body.
Preferably, the buffer layer is a rubber layer.
Preferably, the diagonal length of the steel structure with the square cross section formed by the four supporting steel frames is equal to the length of the inner diameter of the steel structure body.
Compared with the prior art, the utility model has the beneficial effects that:
1. the bridge steel is formed by assembling the cylindrical steel structure body and the four supporting steel frames, so that the using strength of the bridge steel is increased, and the bending deformation of the whole steel structure is reduced;
2. according to the utility model, the buffer layer is filled between the support steel frame and the steel structure body, so that the collision of external impact force on the steel structure is further slowed down, the deformation of the surface of the steel structure body is reduced, and the strength is improved.

the embodiment of the utility model mainly comprises the following component symbols:
the steel structure comprises a steel structure body-1, a supporting steel frame-2, a buffer area-3 and a buffer layer-4.
Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the present invention.
As shown in fig. 1 to 3, a bridge steel construction of preapring for an unfavorable turn of events shape, including steel construction body 1, steel construction body 1 is the drum steel, 1 inner chamber symmetry of steel construction body installs four support steelframes 2, four it is isosceles trapezoid frame, four to support 2 cross-sections of steelframe support the equal fixed contact between two liang of isosceles surfaces of steelframe 2, four it is the steel construction of square, four to support the steelframe 2 constitution cross-section in steel construction body 1 support to form buffer 3 between 2 main extremes of steelframe and the 1 inside wall of steel construction body.
The bridge steel is formed by assembling the cylindrical steel structure body 1 and the four supporting steel frames 2, so that the using strength of the bridge steel is increased, and the bending deformation of the whole steel structure is reduced.
Four support 2 isosceles surfaces of steelframe pass through welded fastening, guarantee the stability of four support 2 installations of steelframe.
The diagonal length of the steel structure with the square cross section formed by the four supporting steel frames 2 is equal to the length of the inner diameter of the steel structure body 1, and the supporting strength of the supporting steel frames 2 to the steel structure body 1 is guaranteed.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
