Specific embodiment
Referring to figs. 1 to Fig. 5, the grouting of the utility model top plate connects prefabricated assembling type reinforced concrete side crashproof guardrail,
Including prefabricated anticollision barrier 20 and precast main beam 10, prefabricated anticollision barrier 20 is constituted and is embedded in inside vertical by concrete prefabricated
To reinforcing bar 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 prefabricated 20 bottom of anticollision barrier stretches out one section, and 10 inside of precast main beam is corresponding with connection reinforcing bar 23
Position built-in metal bellows 11, and outside metal bellows 11 around arrangement stirrup 12 to improve local pressure.
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
The endless all standing metal bellows 11 of guardrail 20 then passes through 11 top opening of metal bellows so that its top has opening
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, is configured inside drip 14 by construction
Reinforcing bar is simultaneously common prefabricated with precast main beam 10.
Preferably, connection reinforcing bar 23 is divided to protrude into connection reinforcing bar 231 and 232 two sections of connection reinforcing bar pre-buried, prefabricated anticollision
Guardrail 20 is embedded with the bottom surface jointing 24 concordant with prefabricated 20 bottom surface of 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 protruded 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 be convenient prefabricated anti-
Hit guardrail 20 it is prefabricated after the completion of storage transport, when site operation, protrude 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.
