Abstract
The utility model discloses an impact proof guard bar, spread foundation, steel pipe concrete column who makes including the concrete and the cable that passes the stand, the spread foundation is prefabricated construction with steel pipe concrete column, and steel pipe concrete column exposes concrete foundation's part and reserves the hole of reeving. This impact proof guard bar has advantages such as intensity height, construction are simple and convenient, factor of safety height.
Description
Technical field
This use is novel belongs to highway facilities field, particularly a kind of anticollision barrier comprising concrete filled steel tube column cable.
Background technology
Along with the development of highway in China traffic technique, mountain highway mileage constantly increases.Mountain highway has that mountain is high, slope is steep, curved anxious, the feature such as sight line is not good, clashes into Frequent Accidents especially at turning, steep cliff section.At present, because mountain highway road width is narrower, limited space, corrugated guardrail and the Cable Barrier adopting hollow steel pipe column more.Facts have proved that the fence upright flexural strength of said structure is lower, under the impact force that errant vehicle high speed is powerful, column often can be caused to bend fracture, and cable loosens phenomenons such as extracting, causes car crash, and economic loss is heavy.Visible, adopt the concrete filled steel tube column of high strength, and the cable fixation of necessity, extremely important for safety, the reliability increasing anti-collision facility.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of crashworthiness and reliability is strong, safety factor is high anticollision barrier.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anticollision barrier, there is concrete foundation 1, column 2 and cable 3, it is characterized in that, described column 2 is external and internal compositions, wherein outside steel pipe 21, inner fill concrete 22, form concrete filled steel tube column, described concrete foundation 1 and concrete filled steel tube column 2 are precast construction, in Transducers Embedded in Concrete basis, described concrete filled steel tube column 2 bottom 1, top exposure, exposure part have pass for cable 3 run through steel pipe and concrete hole 211 of reeving.
Preferably, in the part on the Transducers Embedded in Concrete basis 1 of column 2, steel pipe has perforate 212 in surrounding, is connected with concrete foundation 1 for the concrete in concrete filled steel tube column 2.Therefore more preferably, concrete filled steel tube column 2 and concrete foundation 1 are integrated precasts.
Preferably, the steel pipe that column 2 is used is square-section.
As another preferred version, at cable 3 through after column 2, reeving, hole 211 place utilizes cable stationary fixture 4 to be fixed by cable 3.
In addition, cap 5 is also provided with on column 2 top.
Compared with prior art, the utility model has the advantage of:
Anticollision barrier of the present utility model, by concrete perfusion in rectangular steel pipe column, combine and adopt cable to be connected the form of column in steel pipe bottom opening with basis, flexible at maintenance guardrail, play on the basis of cushioning effect to automobile impacting, substantially increase bending resistance and the shear strength of fence upright, ensure that steel pipe and the connection on basis, enhance the crashworthiness of anticollision barrier.Thus the safety of accident vehicle can be guaranteed, reduce life and property loss.

In the drawings: 1, concrete foundation; 2, column; 3, cable; 4, fixture; 5, cap; 21, steel pipe; 22, concrete; 211, to reeve hole; 212, perforate.
Detailed description of the invention
The utility model discloses a kind of anticollision barrier, comprise spread foundation that concrete makes, concrete filled steel tube column, through the cable of column and the fixture of fixed cable.Described spread foundation and concrete filled steel tube column integral prefabricated, concrete filled steel tube column exceeds the reserved hole of reeving of foundation, and steel pipe is goed deep into foundation and is connected with basic by perforate.Cable, through after railing post, is fixed cable with fixture.This anticollision barrier has that intensity is high, easy construction, safety factor advantages of higher.
Anticollision barrier disclosed in the utility model comprises the spread foundation and concrete filled steel tube column of being made up of concrete, and concrete filled steel tube column is fixed on spread foundation, and base concrete and pipe inner concrete are built simultaneously.
Fence upright steel pipe used is square-section, and expose foundation and be provided with through steel pipe and concrete hole of reeving, steel pipe gos deep into the perforate of foundation tube wall surrounding, ensures to be connected with concrete.Cable, through after column, is fixed at hole place of reeving by fixture by cable.
Described guardrail basis and column are precast construction.
The utility model will be described in detail below further combined with accompanying drawing.
With reference to Fig. 1, anticollision barrier of the present utility model comprises concrete foundation 1 and the concrete filled steel tube column 2 of expansion formula, in Transducers Embedded in Concrete basis, column 2 bottom 1.Cable 3 through column 2 top exposure part, and utilizes fixture 5 to be fixed.Column 2 top is also welded with cap 5.
Again see Fig. 2, be shown specifically the structure of column 2 further.Column 2 top exposure part leaves the hole 211 of reeving running through steel pipe 21 and inner concrete 22 and passes for cable 3.In the part on column 2 Transducers Embedded in Concrete basis 1, steel pipe surrounding also has perforate 212 with the connection of the concrete 22 with concrete foundation 1 that ensure steel duct.
During manufacture, the concrete of concrete foundation 1, concrete filled steel tube column 2 is built simultaneously, integral prefabricated, prefabricated complete after capital welding cap, reach after intensity until concrete, lift to design attitude, then each column is reeved, and be fixed in relevant position with intermediate plate, ensure the acting in conjunction of cable and column.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should cover in the middle of right of the present utility model.
By reference to the accompanying drawings embodiment of the present utility model is described in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
