Abstract
Bridge protection device.Current bridge protection device is many to be made up of elastomeric material, in slight degree of crash process, play good effect, but in unexpected serious collision accident, just seems not enough, make bridge construction be subject to serious damage to the absorption of collision energy.Composition of the present utility model comprises: outside plate leg (1), described outside plate leg is connected with upper and lower two-layer deck (2), crisscross bulkhead (3) is provided with between described outside plate leg and described deck, the surface of described outside plate leg is connected with rhs-structure (4), and described rhs-structure inside is filled with foamed plastics (5).The utility model is used for bridge protection.
Description
technical field:
the utility model relates to a kind of bridge protection device.
background technology:
current bridge protection device is many to be made up of elastomeric material, good effect is played in slight degree of crash process, but in unexpected serious collision accident, the absorption of collision energy is just seemed not enough, make bridge construction be subject to serious damage, bridge application life, safety and shock resistance are all subject to loss to a certain extent.
Utility model content
the purpose of this utility model is to provide a kind of bridge protection device.
above-mentioned object is realized by following technical scheme:
a kind of bridge protection device, its composition comprises: outside plate leg, described outside plate leg is connected with upper and lower two-layer deck, crisscross bulkhead is provided with between described outside plate leg and described deck, the surface of described outside plate leg is connected with rhs-structure, and described rhs-structure inside is filled with foamed plastics.
described bridge protection device, described outside plate leg is connected with sidewall with described deck, and described sidewall is used for being fixed on bridge bearing platform periphery.
described bridge protection device, described rhs-structure is vertically arranged in outside outside plate leg.
described bridge protection device, described rhs-structure interval is arranged in outside described outside plate leg.
described bridge protection device, described foamed plastics adopts 8 node hexahedral elements.
the beneficial effects of the utility model:
the utility model is used for being fixed on bridge bearing platform periphery, and the rhs-structure filling out foam in employing is arranged in outer plate surfaces as power-absorbing, to improve energy absorption ability and the crash-worthiness of safeguard structure outside plate, reduces and hits deeply; By the absorption impact kinetic energy that the plastic strain of self structure is a large amount of, thus eliminate the impact force that is delivered on bridge or make it be reduced to non-demolition level, playing the protective effect to bridge.
accompanying drawing illustrates:
accompanying drawing 1 is external structure schematic diagram of the present utility model.
accompanying drawing 2 is top views of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of bridge protection device, its composition comprises: outside plate leg 1, described outside plate leg is connected with upper and lower two-layer deck 2, crisscross bulkhead 3 is provided with between described outside plate leg and described deck, the surface of described outside plate leg is connected with rhs-structure 4, and described rhs-structure inside is filled with foamed plastics 5.
embodiment 2:
bridge protection device according to embodiment 1, described outside plate leg is connected with sidewall 6 with described deck, and it is peripheral that described sidewall is used for being fixed on bridge bearing platform 7.
embodiment 3:
bridge protection device according to embodiment 1 or 2, described rhs-structure is vertically arranged in outside outside plate leg.
embodiment 4:
bridge protection device according to embodiment 1 or 2, described rhs-structure interval is arranged in outside described outside plate leg.
