Abstract
The utility model discloses a bridge railing, which belongs to the field of highway traffic devices and comprises a buffering structure, a spring device, a collapsing device and a railing. A main body of the buffering structure is a concrete base, the railing is transversely disposed above the concrete base, the spring device comprises an upper upright column and a lower reinforcing bar, the inside of the upright column is a cavity structure, the lower portion of the reinforcing bar is arranged inside the concrete base and fixed with the concrete base via threads, the upper portion of the reinforcing bar extends out of the upper surface of the concrete base and penetrates through the bottom of the upright column, a penetrated portion of the reinforcing bar is sleeved with a spring, a clamp nut is disposed on the reinforcing bar at the upper end of the spring, the collapsing device comprises an elastic component and a compacting part inside the elastic component, and the elastic component is fixed with the railing through a clamp nut. The bridge railing combines rigid pressure resistance with flexible pressure resistance, can effectively reduce breakage damage to the railing due to accidents, and simultaneously decreases loss of vehicles in accidents.
Description
Technical field
The utility model relates to the safeguard in a kind of highway communication field, especially a kind of Bridge guardrail.
Background technology
At present, known Bridge guardrail effect is in order to prevent that vehicle from sweeping away highway when meeting accident accident, cause bigger accident, when night or sight line are bad, play the effect of kerb line, but the guardrail on the existing market mainly is flexible safety fence or stiff safety fence, flexible safety fence normally utilizes cable wire or steel mesh with screen resilience to protect, the stack of concrete that stiff safety fence is normally firm or steel work or above-mentioned two kinds of materials constitutes protection system, because the inertia during vehicle operating is bigger, simple flexible safety fence is not easy to stop vehicle, vehicle is easy to go out guardrail, so not only to the damage of damaging property of guardrail, and the loss of accident vehicle is also very huge, though and stiff safety fence can stop vehicle to sweep away guardrail, but stiff safety fence can cause the secondary injury to accident vehicle mostly, especially to vehicle collision on guardrail, the consequence that two rigid objects collide is very serious, simultaneously, guardrail is in case disorderly flown everywhere after being broken also easily to damage to the accident vehicle vehicle of having passed by on one's way, therefore, and for solving the deficiency of existing guardrail, be badly in need of a kind ofly can either playing the guardrail that protection can be played cushioning effect again the loss after the minimizing accident takes place.
Summary of the invention
At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of buffer structure that possesses the rigidity erosion control, spring setting that flexibility is dissolved impact force and the Bridge guardrail of emergency reaction collapsing structure, can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: Bridge guardrail comprises buffer structure, spring assembly, buckling device and railing, the main body of described buffer structure is a concrete pedestal, described railing laterally is located at the top of concrete pedestal, described spring assembly comprises the column on top and the reinforcing bar of bottom, the inside of column is cavity structure, the bottom of reinforcing bar places in the concrete pedestal, and fix with the concrete pedestal screw thread, the top of reinforcing bar is paid the upper surface of concrete pedestal and is passed the bottom of column, reinforcing bar expenditure concrete pedestal and be positioned on the position of column and be with spring, on the reinforcing bar of spring upper end, be provided with clamp nut, described buckling device comprises the compression piece of elastic fibrous tissue and elastic fibrous tissue inside, and elastic fibrous tissue links to each other with railing, and compression piece and railing are perpendicular.
As preferably, the outside of described elastic fibrous tissue is provided with the rubber-like rubber sleeve, and the compression piece of elastic fibrous tissue inside is the compression spring.
As preferably, described elastic fibrous tissue and railing are fixed by fastening bolt.
As preferably, the front of described column is the arcwall face of indent.
As preferably, the top in described concrete pedestal front is the buffering cambered surface towards indent.
As preferably, the upper surface of described concrete pedestal has the screwed hole of vertical direction, and screwed hole is deep into the middle part of concrete pedestal, and the surface of described reinforcing bar is provided with and the corresponding external screw thread of screwed hole.
Compared with prior art, the beneficial effect that this utility model is brought is: this utility model possesses the buffer structure of rigidity erosion control simultaneously, flexibility is dissolved the spring assembly of impact force and the buckling device of emergency reaction, simple in structure, rigidity and flexible resistance to compression are combined, effectively minimizing accident is to the destructiveness damage of guardrail, also can reduce simultaneously the loss of accident vehicle, after accident takes place, accident vehicle has reduced the part impact force after at first impacting the arcwall face of rigid concrete pedestal, buckling device on it and spring assembly can be dissolved remaining impact force, therefore, can be by of the destructiveness damage of effectively minimizing accident of said structure to guardrail, reduce the loss of accident vehicle, avoid accident that the injury of back to the vehicle of passing by on one's way takes place simultaneously.
