Abstract
The utility model discloses a steel pipe concrete box bridge for resisting large deformation in a high fill area, which is in the shape of a rectangular pipe, and the inner edge of the rectangular pipe is provided with a chamfer; the device comprises a bottom plate and a top plate, wherein two sides of the bottom plate and two sides of the top plate are connected through a vertical plate; a group of transverse steel pipes along the running direction of the vehicle are arranged in the bottom plate and the top plate, and a group of vertical steel pipes are arranged in the vertical plate; and double-layer bidirectional steel bars are arranged between the transverse steel pipes and the plate walls and between the vertical steel pipes and the plate walls. The utility model discloses a reinforced concrete box frame bridge replaces traditional reinforced concrete box frame bridge, and in the high district engineering construction within range of filling, the rational utilization reinforced concrete stress characteristic has good mechanical properties, can have the ability of bigger anti ground big deformation, simultaneously, can comparatively reduce the quantity of concrete and reinforcing bar. The construction resource waste of the high fill area can be reduced, the project investment is greatly reduced, the construction is convenient, the construction efficiency can be effectively improved, and the aim of accelerating the project construction progress is finally achieved.
Description
Technical field
the utility model relates to a kind of concrete filled steel tube box bridge for the distortion of the Chinese People's Anti-Japanese Military and Political College of high roadbed district, belongs to civil engineering bridge construction technical field.
Background technology
in civil works, sometimes need to construct a bridge in high roadbed district, because high roadbed district ground easily produces very large foundation deformation, will certainly cause according to existing bridge beam slab structure that sectional dimension is excessive, material usage is many, the problem of high cost.Therefore, when ensureing bridge beam slab structural safety, improve stock utilization, the waste reducing resource is a urgent problem.
Utility model content
the purpose of this utility model is, provides a kind of concrete filled steel tube box bridge for the distortion of the Chinese People's Anti-Japanese Military and Political College of high roadbed district, to improve stock utilization, has subtracted the waste of few resource, finally reach the object of saving engineering cost.
the technical solution of the utility model:
for a concrete filled steel tube box bridge for the Chinese People's Anti-Japanese Military and Political College of high roadbed district distortion, the shape of described concrete filled steel tube box bridge is rectangular tubular, and the inner edge of rectangular tube is provided with chamfering; Comprise base plate and top board, base plate is connected through riser with top board both sides; Be provided with one group of horizontal steel pipe along vehicle heading in base plate and top board, in riser, be provided with one group of vertical steel pipe; Horizontal steel pipe and be provided with double-layer double-direction reinforcing bar between vertical steel pipe and wooden partition.
in aforementioned concrete filled steel tube box bridge, described horizontal steel pipe and vertical steel pipe are filled with the concrete solid steel pipe with bridge ad eundem in hollow steel pipe or pipe.
in aforementioned concrete filled steel tube box bridge, described double-layer double-direction reinforcing bar is positioned at steel pipe both sides row's muscle evenly distributed in length and breadth.
compared with prior art, the present invention adopts concrete filled steel tube boxed frame bridge to substitute traditional steel concrete box frame bridge beam, within the scope of the engineering construction of high roadbed district, Appropriate application concrete filled steel tube mechanical characteristic, there is good mechanical property, the ability of larger anti-large subsoil distortion can be had, meanwhile, comparatively can reduce the consumption of concrete and reinforcing bar.The bridge construction adopting this practical concrete filled steel tube box frame bridge to form can reduce the Resources for construction waste of high roadbed district, significantly reduces construction investment, easy construction, effectively can improve efficiency of construction, finally reach the object accelerating engineering construction progress.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the top view of Fig. 1.
being labeled as in accompanying drawing: 1-base plate, 2-top board, 3-riser, the horizontal steel pipe of 4-, 5-vertical steel pipe, 6-and bridge ad eundem concrete, 7-double-layer double-direction reinforcing bar, 8-chamfering.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
for a concrete filled steel tube box bridge for the Chinese People's Anti-Japanese Military and Political College of high roadbed district distortion, as depicted in figs. 1 and 2: the shape of described concrete filled steel tube box bridge is rectangular tubular, and the inner edge of rectangular tube is provided with chamfering 8; Comprise base plate 1 and top board 2, base plate 1 is connected through riser 3 with top board 2 both sides; Be provided with one group of horizontal steel pipe 4 along vehicle heading in base plate 1 and top board 2, in riser 3, be provided with one group of vertical steel pipe 5; Horizontal steel pipe 4 and be provided with double-layer double-direction reinforcing bar 7 between vertical steel pipe 5 and wooden partition.Horizontal steel pipe 4 and vertical steel pipe 5 are filled with the solid steel pipe with bridge ad eundem concrete 6 in hollow steel pipe or pipe.Double-layer double-direction reinforcing bar 7 is positioned at steel pipe both sides row's muscle evenly distributed in length and breadth.
Embodiment
before building bridge member, as depicted in figs. 1 and 2.In the base plate 1 and top board 2 of bridge member, arrange one group of horizontal steel pipe 4 uniformly along vehicle heading, arrange one group of vertical steel pipe 5 at the riser 3 of bridge member.Horizontal steel pipe 4 and vertical steel pipe 5 evenly distributed, and to be fixed by the steel mesh reinforcement that double-layer double-direction reinforcing bar 7 is formed, and then the component carrying out bridge member is built.The endoporus template of bridge member on the corner adopts chamfering structure, to eliminate the internal stress of bridge member.Adopt bridge construction of the present utility model, although add tube material, can reduce the consumption of reinforcing bar, the sectional area of bridge member can not increase much simultaneously, can meet the requirement of strength of bridge.Described steel pipe can adopt hollow steel pipe, for the bridge that requirement of strength is higher, also can build at steel pipe and form solid steel pipe with the concrete of bridge member ad eundem.
