Abstract
The utility model relates to a T-shaped beam of 50m, while T-shaped beam is generally applied at the upper structure of assembly-type highway bridges and is suitable for the standard span length of 20 to 40m, and the assembly-type highway bridge is generally shaped in T-form shorter than 40m. The 50m T-shaped beam comprises a beam body (3) connected with a horseshoe base (1) connected with a beam rib (2). The T-shaped beam of 50m can be used as an assembly-type highway bridge.
Description
Technical field:
The utility model relates to 50 meter T-shaped beams that use in a kind of building.
Background technology:
The medium and small footpath bridge of striding of China has adopted prestressed concrete simply supported beam slab bridge more and more, and this fabricated freely-supported beam slab is stressed clear and definite, easy construction, good endurance.Particularly recent, along with Freeway Development, China medium and small new material, new technology of striding the footpath prestress concrete girder slab use and method for designing on remarkable progress is all arranged, therefore, the technology of conscientiously studying this respect has crucial meaning.
T type beam is a kind of form of structure that highway assembling bridge superstructure often adopts, and is applicable to that generally 20 meters to 40 meters standard is striden the footpath, and the assembling highway bridge is common in the T type bridge below 40 meters.
Summary of the invention:
The purpose of this utility model provides a kind of footpath assembling 50 meter T-shaped beams of striding greatly, can reduce construction costs.
Above-mentioned purpose realizes by following technical scheme:
50 meter T-shaped beams, its composition comprises: the beam body, described beam body is connected with horseshoe base, described horseshoe base tie-beam rib.
The beneficial effects of the utility model:
1. this product rebuilds stress model by horseshoe base, problem such as overcome the lateral bending that occurs in the long-span bridge beam, topple.
2. use this product can reduce construction costs, the visual field of open descending route reduces the accident rate of descending vehicle.
3. this product has positive facilitation to the development of simply supported girder bridge.Adopt this product to cross over high-grade highway and can save row's bridge pier, stride 20 meters or 30 meter T-shaped beams and compare with two, ten thousand yuan of the 70-80 of can reducing investment outlay this shows its economic benefit highly significant.
Description of drawings:
Accompanying drawing 1 is the plane structure schematic diagram of this product.
Accompanying drawing 2 is facade structures schematic diagrames of this product.
The specific embodiment:
Embodiment 1:
50 meter T-shaped beams, its composition comprises: beam body 3, described beam body is connected with horseshoe base 1, described horseshoe base tie-beam rib 2.
Because 50 meter T-shaped beams deadweights is bigger, so T type beam pedestal, basis are especially important.According to beam prefabricated each the stage pedestal stressing conditions of T type, pedestal and basis are carried out arrangement of reinforcement.Behind every prefabricated intact a slice T type beam, check with level gauge whether base is out of shape, so that in time adjust.
50 meter T-shaped beams are not established antiarch from weighing 150 tons, and deck-molding reaches 2.5 meters, and center of gravity is very high, and is on beam rib center line, not bad as transversely strengthening, can cause the beam body to tilt, lateral force, and beam fractures.
It strides the footpath near Limiting Level to 50 meter T-shaped beams in the simply supported beam beam bridge, and its construction technology is in advanced level in the whole nation, in applications such as bridge crossing, speedway viaduct vast potential for future development is arranged.
Claims (1)
1. meter T-shaped beam, its composition comprises: the beam body is characterized in that: described beam body is connected with horseshoe base, described horseshoe base tie-beam rib.
