Specific implementation mode
Referring to figs. 1 to Fig. 5, top plate grouting connection prefabricated assembling type reinforced concrete side crashproof guardrail of the present invention, including
Prefabricated anticollision barrier 20 and precast main beam 10, prefabricated anticollision barrier 20 are constituted by concrete prefabricated and are embedded with longitudinal steel in inside
Muscle 21, bending resistance reinforcing bar 22 and connection reinforcing bar 23, longitudinal reinforcement 21 is longitudinally arranged, and bending resistance reinforcing bar 22 is arranged around a circle, connection
Reinforcing bar 23 extends outwardly from 20 bottom of prefabricated anticollision barrier stretches out one section, 10 inside of precast main beam position corresponding with connection reinforcing bar 23
Built-in metal bellows 11 is set, and arrangement stirrup 12 is surround to improve local pressure outside metal bellows 11.
When installation, mortar bed 30 is arranged in corresponding position first above precast main beam 10, later hoisting prefabricated anticollision shield
Connection reinforcing bar 23 is simultaneously inserted into metal bellows 11, when precast main beam 10 is docked with prefabricated anticollision barrier 20, prefabricated anticollision by column 20
20 endless all standing metal bellows 11 of guardrail so that its top has opening, then passes through 11 open top of metal bellows
Grouting material is perfused, the length that connection reinforcing bar 23 is inserted into metal bellows 11 should meet anchorage length requirement, and grouting material selects UHPC
Material.
10 end of precast main beam upwardly extends the block 13 to be formed with the cooperation positioning of prefabricated anticollision barrier 20, prefabricated to resist
The horizontal thrust of anticollision barrier 20.Drip 14 is set below 10 end of precast main beam, and 14 inside of drip is by construction configuration
Reinforcing bar is simultaneously common prefabricated with precast main beam 10.
Preferably, connection reinforcing bar 23 is divided to stretch into connection reinforcing bar 231 and pre-buried 232 two sections of connection reinforcing bar, prefabricated anticollision
Guardrail 20 is embedded with the bottom surface jointing 24 concordant with 20 bottom surface of prefabricated anticollision barrier, and pre-buried connection reinforcing bar 232 is embedded in pre-
Inside anticollision barrier 20 processed, and pre-buried 232 bottom of connection reinforcing bar is fixedly connected with jointing 24, is stretched into connection reinforcing bar 231 and is pushed up
Portion and 24 detachable connection of jointing, are preferably threaded, and two sections of settings of connection reinforcing bar 23 can facilitate prefabricated anti-
Hit guardrail 20 it is prefabricated after the completion of storage transport, when site operation, stretch into connection reinforcing bar 231 and be connected to jointing 24, then
In place by the lifting of prefabricated anticollision barrier 20, finally to grouting material is perfused inside metal bellows 11.
Certainly, to reduce bridge deck width, the setting of block 13 can be cancelled, and setting is cut in 20 bottom of prefabricated anticollision barrier
Power slot 26 and go out glue groove 27, go out 27 longitudinally spaced arrangement of glue groove, correspondingly, precast main beam 10 is equipped with matches with shearing 26 build-in of slot
The shear connector 15 of conjunction, and drip 14 is moved into 10 end of precast main beam.In 20 bottom surface of prefabricated anticollision barrier and precast main beam 10
