Abstract
The utility model discloses a cement concrete anti-collision isolation guardrail connecting piece which is used for connecting two adjacent cement concrete anti-collision isolation guardrails. The connecting piece is formed by transverse T-shaped connecting pieces arranged on a left end face and a right end face of each cement concrete anti-collision isolation guardrail and a C-shaped connecting piece. Inserting coupling pieces are prefabricated on two end faces of each cement concrete anti-collision isolation guardrail, no extra connecting piece is used to enable the cement concrete anti-collision isolation guardrails to become a flexible connecting whole, and acting force of the anti-collision isolation guardrails is improved.
Description
Technical field
The utility model relates to anticollision barrier, particularly the crashproof isolation guardrail connector of a kind of cement concrete.
Background technology
Anticollision barrier can effectively stop vehicle to be gone out as the important safety facility of highway and bridge, reduces Traffic Accident Loss, is used widely.Anticollision barrier can be divided into stiff safety fence, semi-rigidity rail and flexible safety fence three classes by operating characteristic.Substantially indeformable guardrail form referred generally to concrete guardrail after stiff safety fence was collided by automobile.The board-like guardrail of concrete wall adopts the concept of " safe profile ", mainly by the different side of the profile gradient, make car deceleration in the collision process, climb, turn to, and guardrail is substantially indeformable.It is that potential energy slows down vehicle along horizontal the moving of guardrail by self distinctive ramp structure lifting vehicle's center of gravity with the kinetic transformation of vehicle mainly, potential energy is converted into the purpose that the heterodromous kinetic energy of vehicle is realized back positive vehicle heading again.
The manufacturing of concrete guardrail, maintenance and maintenance cost are low, need not keep in repair generally speaking, can build installation, also can directly stand on the ground.But the concrete guardrail majority is the section of being prefabricated into, and is relatively independent between each section after installing; When Vehicular impact, only have force block to react on vehicle, and adjacent block does not have effect to vehicle, guardrail just can't form as a wholely like this, can not absorb the energy of Vehicular impact, thereby cause vehicle to go out guardrail, leads to a disaster.
Summary of the invention
The technical problems to be solved in the utility model provides the crashproof isolation guardrail connector of a kind of cement concrete, they are prefabricated grafting couple on the both ends of the surface of the crashproof isolation guardrail of cement concrete, can not make the crashproof isolation guardrail of cement concrete become the integral body that flexibly connects by any extra connector, improve the active force of crashproof isolation guardrail.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
The crashproof isolation guardrail connector of a kind of cement concrete, be used for connecting adjacent two crashproof isolation guardrails of cement concrete, described connector is made of " ┝ " type connector on left and right two end faces that are arranged on the crashproof isolation guardrail of cement concrete and " C " type connector.
Described " ┝ " type connector and " C " type connector are the steel built-in fitting, respectively with the crashproof isolation guardrail of cement concrete in the cage of reinforcement welding.
Described " ┝ " type connector is " ┝ " type or I shape.
The upper end of described " C " type connector opening part is for being " V " type.
The beneficial effect that adopts technique scheme to produce is: 1) the utility model is in the each independently both sides of the crashproof isolation guardrail of cement concrete are prefabricated grafting couple, only need " ┝ " type connector with the crashproof isolation guardrail of one of them cement concrete be plugged in the groove of " C " type connector of the crashproof isolation guardrail of cement concrete that is adjacent during construction, can be by the be connected to form integral body that flexibly connects of groove with " ┝ " type or I shape connector, need to can not realize by any other extra connector the connection of crashproof isolation guardrail, it installs simple, and is time saving and energy saving; 2) when Vehicular impact arrives certain section crashproof isolation guardrail of cement concrete of the present utility model, because being, itself and the adjacent crashproof isolation guardrail of cement concrete flexibly connect, impact can be reached on the coupled crashproof isolation guardrail of other several cement concretes, reduced the impact to the crashproof isolation guardrail of single hop cement concrete, thereby reduced the loss that collision brings, be down to the loss of traffic accident minimum; 3) because the crashproof isolation guardrail of each cement concrete is to flexibly connect, and " ┝ " type connector and " C " type connector are cast steel, its deformability is larger than cement concrete, has increased the endergonic ability of isolation guardrail, has the rigidity of stiff safety fence and the toughness of semi-rigidity rail; 4) when the utility model separates opposed vehicle for highway central authorities, can be directly from the groove insertion antiglare shield on " C " type connector top, it is convenient to install.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of horizontal direction of the present utility model;
Fig. 2 is perspective view of the present utility model;
Wherein, 1, " ┝ " type connector, 2, the crashproof isolation guardrail of cement concrete, 3, groove, 4, " C " type connector, 5, the opening of " C " type connector.
The specific embodiment
Referring to Fig. 1 and Fig. 2, connector of the present utility model is made of " ┝ " type connector on left and right two end faces that are arranged on the crashproof isolation guardrail 2 of cement concrete and " C " type connector 4." ┝ " type connector of a crashproof isolation guardrail of cement concrete is plugged in the groove 3 of " C " type connector 4 of the guardrail that is adjacent, " C " type connector 4 is surrounded by the retaining wall at groove 3 and opening 5 places, both can prevent that " ┝ " type connector from deviating from groove 3, owing to existing the gap between the two, " C " type connector 4 has formed again with " ┝ " type connector and has flexibly connected.
Described " ┝ " type connector and " C " type connector 4 are steel or cast steel built-in fitting, with the cage of reinforcement welding in the crashproof isolation guardrail 2 of cement concrete, imbed before precast concrete.Cast steel, deformability obviously are better than cement concrete, and the rigidity that makes the utility model not only have stiff safety fence also has the toughness of semi-rigidity rail simultaneously.
Described " ┝ " type connector not only can be " ┝ " type but also I shape, such as i iron.
The upper end at opening 5 places of described " C " type connector is for being " V " type.Be convenient to like this grafting of " ┝ " type connector.
Prefabricated operation of the present utility model: welded reinforcement skeleton at first, " ┝ " type connector and " C " type connector 4 are welded on the cage of reinforcement of guardrail, joints cement concrete then, maintenance gets final product.
During construction, " ┝ " type connector 1 of the crashproof isolation guardrail of cement concrete is plugged in the groove 3 of " C " type connector 4 of the crashproof isolation guardrail of cement concrete that is adjacent, prevents that by " C " type connector 4 " ┝ " type connector 1 from deviating from groove 3.
When vehicle hits certain section crashproof isolation guardrail of cement concrete, it is delivered to impact on the crashproof isolation guardrail of cement concrete of adjacent segment, except the effect that stiff safety fence should play, can also by the distortion absorption portion Impact energy of " ┝ " type connector 1 and " C " type connector 3, farthest reduce the bump loss in the utility model.
