Abstract
The utility model discloses a support joist structure for a horizontal-drawing cable bridge pull rod. The support joist structure comprises a top plate, a web, a bottom plate and a pull rod fixed on the top plate, wherein the pull rod and the bottom plate are fixed at the upper end and the lower end of the web respectively; the bottom plate is horizontal; the web is vertical to the bottom plate; the top surface of the top plate is oblique; a plurality of check blocks and vertical blocks are arranged on the top plate, and are fixed together by welding; the top plate, the web and the bottom plate are fixed together by welding. Since the top surface of the support joist is oblique to the direction of the pull rod direction and has the same angle as the inclination angle of the pull rod, the pull rod supporting requirement can be well met, the pull rod does not need to be bent, and damages to the pull rod are reduced; due to the arrangement of the check blocks and the vertical blocks, the mounting and positioning requirements are met by the support joist, and transverse load transferred by a steel cable can be met; the support joist structure has the advantages of safety, reliability, simple structure, saving of materials and convenience in construction, and can be widely popularized and applied to the technical field of bridge construction.
Description
Technical field
The utility model relates to a kind of supporting joist structure for horizontal drawing cable bridge pull bar, belongs to bridge structure technical field.
Background technology
As everyone knows, road, pipeline or other conveying engineerings need construct a bridge when crossing over river cheuch, in numerous bridge types, horizontal drawing cable bridge as a kind of common bridge type because its cost is low, construction speed fast, easy construction is used widely.Horizontal drawing cable bridge belongs to flexible structure, and its load acts directly on cable wire, and cable wire is connected with the pull bar in being anchored in basis, by pull bar, full-bridge load is delivered in the massif of two sides.Therefore, the pull bar quantity in basis is more, and its installation quality relates to the safety of bridge.Supporting joist is the supporting construction of pull bar, plays again the installation positioning action of pull bar.
In the prior art, the supporting joist of pull bar generally adopts rail.The end face of this supporting joist structure is the level of state, and there is certain angle in pull bar and its end face, thereby pull bar need be bent near the position of supporting joist, so not only reduced the intensity of pull bar, and increased trouble to construction, meanwhile, rail size is larger, material usage is more, has greatly increased construction cost.Therefore, traditional stable girder construction is unsatisfactory.
Utility model content
The purpose of this utility model is to overcome the existing deficiency of prior art, a kind of supporting joist structure of horizontal drawing cable bridge pull bar is provided, this supporting joist structure can meet supporting and the positioning requirements of horizontal drawing cable bridge pull bar, the direction across bridge load that cable wire passes over be can bear again, material, easy construction saved simultaneously.
The utility model is achieved by following technical solution.
A kind of supporting joist structure for horizontal drawing cable bridge pull bar, comprise top board, web, base plate and be fixed on the pull bar on top board, described top board and base plate are separately fixed at the top and bottom of web, described floor level, web is perpendicular to base plate, Roof face tilt is arranged some blocks and vertical block on top board, and together with block is welded and fixed with vertical block.
Described top board, web and base plate adopt welding manner to be fixed together.Make like this it connect reliable.
Described top board tilts to pull bar direction, and its angle of inclination is identical with pull bar.
The position of described block on top board and the layout of pull bar match, and pull bar is near block.
Described vertical block is welded with top board and block respectively.
The quantity of described vertical block is less than or equals the quantity of block.
The beneficial effects of the utility model are:
Compared with prior art, the utility model supports the structure of joist by change, to adapt to the angle of inclination of pull bar; Meet the needs that pull bar is installed location and born cable wire transverse load simultaneously.Because the end face that supports joist is to pull bar direction inclination and identical with the angle of inclination of pull bar, thereby can adapt to preferably pull bar supporting requirement, also not need pull bar to bend processing, thereby reduce the damage to pull bar; Owing to being provided with block and vertical block, make to support the needs that joist had both met pull bar installation location, can bear the transverse load that cable wire passes over again; On the other hand, simply, material usage is more economized for the processing of this supporting joist structure, installation.The utility model is safe and reliable, and simple structure is saved material, and easy construction, can be in bridge structure technical field wide popularization and application.
