Abstract
The utility model relates to a box beam and aims at providing the box beam which has a low manufacturing cost and a high deck utilization rate. According to the technical scheme for realizing the purpose, the box beam comprises a top plate, top plate flange girths, a bottom plate and a web plate. The box beam is characterized in that cantilevers extend out of two sides on the bottom plate; the upper surfaces of the cantilevers are provided with deck pavements; and ground beams are erected on the bottom plate at intervals.
Description
Technical background
The utility model relates to a kind of case beam.
Background technology
The case beam is a kind of of bridge engineering central sill, and inside is hollow shape, and there is the edge of a wing both sides, top, similar chest, thereby gain the name.In traditional box bridge structure, adopt the top board and the top board edge of a wing usually as the supporting bridge floor.Along with China's economy constantly develops; The traffic volume is increasing, thus bridge width especially the width of Urban Bridge also continue to increase, so the width of conventional boxes beam also constantly strengthens; The structure construction size needs corresponding increase; The corresponding increase of substructure engineering quantity, taking up an area of also simultaneously constantly increases, and directly causes construction costs to strengthen.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and the case that a kind of cost is low, the bridge floor utilization rate is high beam is provided.
The technical scheme that realizes the utility model purpose is: a kind of case beam, comprise top board, the top board edge of a wing, base plate and web, and it is characterized in that cantilever is stretched out in both sides on the said base plate, the cantilever upper surface is provided with deck paving, and said base plate has whenever set up grade beam at a distance from a segment distance.
As the further improvement of the utility model, the end of cantilever is provided with guardrail in said both sides.
The utility model is through stretching out cantilever at case beam base plate; And whenever set up grade beam at a distance from a segment distance in case beam internal backplane, and strengthen base plate cantilever rigidity, deck paving is set on cantilever; In cantilevered distal end guardrail is set; Utilize jib-length as motorway or bicycle and sidewalk, form lower floor's bridge floor, form two-layer bridge deck structure with upper strata top board bridge floor.
Adopt technique scheme, in Urban Bridge, adopt levels to separate with nonmotorized vehicle lane and sidewalk on motor vehicle; Strengthen current safety, owing to the space under the top board cantilever that has made full use of the case beam, reduced bridge deck width simultaneously; Reduce land used, reduced cost on the whole.Solved the contradiction between the increase of traffic dilatation and land used effectively, especially had wide practical use in the city box girder bridge beam, had good popularization value at the box girder bridge beam.
The utility model corresponding construction construction features:
1, case beam base plate stretches out cantilever;
2, case beam internal backplane is provided with little grade beam;
3, the cantilever end is provided with guardrail;
4, on the cantilever deck paving is set.
Description of drawings
Fig. 1 is embodiment 1 structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of case beam 10 comprises top board 1, the top board edge of a wing 4, base plate 2 and web 3, and cantilever 6 is stretched out in base plate 2 both sides, and cantilever 6 upper surfaces are provided with deck paving, has whenever set up grade beam 5 at a distance from a segment distance on the base plate 2, and the end of cantilever is provided with guardrail 7 in both sides.
Claims (2)
1. a case beam comprises top board, the top board edge of a wing, base plate and web, it is characterized in that cantilever is stretched out in both sides on the said base plate, and the cantilever upper surface is provided with deck paving, and said base plate has whenever set up grade beam at a distance from a segment distance.
2. case beam according to claim 1 is characterized in that, the end of cantilever is provided with guardrail in said both sides.
