Abstract
本实用新型公开一种端部加厚箱梁结构，包括顶板、顶板翼缘、底板和两腹板，所述顶板和所述底板对立设置，两所述腹板对立设置在所述顶板和所述底板之间，所述顶板、底板和两腹板围合形成一个两端开口的空心腔体，所述顶板翼缘由所述顶板的两侧向外延伸设置；其中，所述底板面向所述空心腔体的内侧面为一平面，所述底板背向所述空心腔体的外侧面为一凹陷面，所述底板的两端部厚度大于所述底板中间段厚度。本实用新型由于底板两端部向外加厚，所以箱梁两端部能更好的匹配其所对应的应力，且由于底板是向外凸起加厚的，相较之内加厚或其他方式，本实用新型更加容易进行加工构筑，故有效的降低了箱梁结构的制作难度，尤其适合于采用模具进行预制或现浇施工。
The utility model discloses a box girder structure with thickened ends, which comprises a top plate, a top plate flange, a bottom plate and two webs, the top plate and the bottom plate are oppositely arranged, and the two webs are oppositely arranged on the top plate and the bottom plate. Between the bottom plates, the top plate, the bottom plate and the two webs enclose to form a hollow cavity with openings at both ends, and the flanges of the top plate extend outward from both sides of the top plate; wherein, the bottom plate faces the The inner surface of the hollow cavity is a plane, the outer surface of the bottom plate facing away from the hollow cavity is a concave surface, and the thickness of both ends of the bottom plate is greater than the thickness of the middle section of the bottom plate. In the utility model, since the two ends of the bottom plate are thickened outward, the two ends of the box girder can better match the corresponding stress, and because the bottom plate is protruding and thickened, it is thicker than the inside or other In this way, the utility model is easier to process and construct, so it effectively reduces the manufacturing difficulty of the box girder structure, and is especially suitable for prefabrication or cast-in-place construction using molds.
Description
Technical field
The utility model relates to the technical field of bridge engineering, relates in particular to a kind of box-beam structure.
Background technology
The case beam is a kind of of bridge engineering central sill, and inside is hollow cavity, and there is the edge of a wing both sides, top, similar chest, thereby gain the name.The case beam of reinforced concrete structure is divided into prefabricated case beam and cast-in-situ box girder.The case beam prefabricated in independent place can set up after the bottom engineering is finished in conjunction with the bridge formation machine, can accelerate programming, save the duration.Cast-in-situ box girder is used for the Large Scale and Continuous bridge more.The case beam is in application, usually suffered stress can be greater than the centre position in the position at its both ends, so present most case beams all can in the hollow cavity of case beam, thicken base plate thickness by the centre gradually to the position, both ends, the appearance and size of case beam and shape invariance, the both ends of constructing boring cavity bottom surface are higher than mid portion, so can the appropriate stress demand that satisfies diverse location.But in manufacturing process, the inventor finds that existing box-beam structure difficulty of construction is higher, especially is not easy to adopt mould to carry out prefabricated or cast-in-place construction, and construction is inconvenience comparatively, is necessary to further improve.
The utility model content
Because the above-mentioned deficiency of prior art, the utility model proposes a kind of when opening, can avoid waste water or greasy dirt flow to into, and when closure, do not influence the end-thickened box-beam structure of the normal use of upper space.
For achieving the above object, the utility model provides a kind of end-thickened box-beam structure, comprise top board, the top board edge of a wing, base plate and two webs, described top board and described base plate opposition arrange, two described web opposition are arranged between described top board and the described base plate, described top board, base plate and two webs surround the hollow cavity that forms a both ends open, and the described top board edge of a wing is by the setting that stretches out of the both sides of described top board; Wherein, described base plate is a plane towards the medial surface of described hollow cavity, and the described base plate lateral surface of described hollow cavity dorsad is a concave face, and the both ends thickness of described base plate is greater than described base plate interlude thickness.
Preferable, connect on the described base plate and be provided with spilled water hole.
Preferable, be provided with some crossbeams in the described hollow cavity.
Preferable, the lateral surface at described base plate both ends is provided with pre-embedded steel slab and bearing cushion block, and described pre-embedded steel slab is arranged on the lateral surface at described base plate both ends, and described bearing cushion block is arranged on the described pre-embedded steel slab.
Preferable, to be that steel concrete is one-body molded be connected for described top board, the top board edge of a wing, base plate and two webs.
End-thickened box-beam structure beneficial effect of the present utility model is: end-thickened box-beam structure of the present utility model since the base plate both ends to external upset (EU), so its corresponding stress can better be mated in case beam both ends, and because base plate is thickeied to outer lug, thickening or other modes within comparing, end-thickened box-beam structure of the present utility model is more prone to process to be constructed, so effectively reduced the manufacture difficulty of box-beam structure, be particularly suitable for adopting mould to carry out prefabricated or cast-in-place construction.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, feature and effect fully.

The specific embodiment
Fig. 1 partly cuts open structural representation for end-thickened box-beam structure.Fig. 2 is Fig. 1 left view.As shown in the figure, the end-thickened box-beam structure of present embodiment comprises top board 1, the top board edge of a wing 4, base plate 2 and two webs 3, top board 1 and base plate 2 opposition arrange, two webs, 3 opposition are arranged between top board 1 and the base plate 2, top board 1, base plate 2 and two webs 3 surround the hollow cavity 5 that forms a both ends open, and the top board edge of a wing 4 is by the setting that stretches out of the both sides of top board 1; Wherein, base plate 2 is a plane towards the medial surface 21 of hollow cavity 5, and base plate 2 lateral surface 22 of hollow cavity 5 dorsad is a concave face, and the both ends thickness of base plate 2 is greater than base plate 2 interlude thickness.
As the further specific embodiment of present embodiment, be provided with some spilled water holes 9 in base plate 2 perforations.In hollow cavity 5, be provided with some crossbeams 6.Lateral surface 22 at base plate 2 both ends is provided with pre-embedded steel slab 7 and bearing cushion block 8, and pre-embedded steel slab 7 is arranged on the lateral surface 22 at base plate 2 both ends, and bearing cushion block 8 is arranged on the described pre-embedded steel slab 7.In addition, top board 1, the top board edge of a wing 4, base plate 2 and two webs 3 are connected for steel concrete is one-body molded, and directly assembly unit mould concreting is constructed.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
