Specific embodiment
Referring to figs. 1 to Fig. 5, the grouting of the utility model guardrail connects prefabricated assembling type reinforced concrete side crashproof guardrail,
Including prefabricated anticollision barrier 20 and precast main beam 10, precast main beam 10 has the connection reinforcing bar 11 for extending and stretching out, prefabricated anticollision shield
Column 20 is constituted by concrete prefabricated and is embedded with longitudinal reinforcement 21, bending resistance reinforcing bar 22, distributing bar 23, stirrup 24 and gold in inside
Belonging to bellows 25, longitudinal reinforcement 21 is longitudinally arranged, and metal bellows 25, which runs through, is embedded in prefabricated 20 side part of anticollision barrier,
And local structure thicker processing is carried out, stirrup 24 is looped around outside metal bellows 25, to improve local pressure, distributing bar 23
It is welded to connect with stirrup 24 and forms one, the top and bottom of metal bellows 25 all have opening.
When installation, mortar bed 30 is arranged in corresponding position first above precast main beam 10, later hoisting prefabricated anticollision shield
Connection reinforcing bar 11 is simultaneously inserted into metal bellows 25 by column 20, grouting material then is perfused by 25 top opening of metal bellows, even
Anchorage length requirement should be met by connecing reinforcing bar 11 and being inserted into the length of metal bellows 25, with mortar by prefabricated anticollision barrier 20 after grouting
Surface smoothes out.Grouting material selects UHPC material.
10 end of precast main beam upwardly extends the block 12 to be formed with the cooperation positioning of prefabricated anticollision barrier 20, prefabricated to resist
The horizontal thrust of anticollision barrier 20.Drip 13 is set below 10 end of precast main beam, is configured inside drip 13 by construction
Reinforcing bar is simultaneously common prefabricated with precast main beam 10.
Preferably, connection reinforcing bar 11 is divided to protrude into connection reinforcing bar 111 and 112 two sections of connection reinforcing bar pre-buried, precast main beam
10 are embedded with the jointing 14 of top surface Yu precast main beam either flush, and pre-buried connection reinforcing bar 112 is embedded in inside precast main beam,
And pre-buried 112 top of connection reinforcing bar is fixedly connected with jointing 14, protrudes into connection 111 bottom of reinforcing bar and jointing 14 is removable
Unload formula connection, be preferably threaded, two sections of reinforcing bar 11 settings of connection, can be convenient precast main beam 10 it is prefabricated after the completion of deposit
It puts transport, when site operation, protrudes into connection reinforcing bar 111 and be connected to jointing 14, be then lifted into prefabricated anticollision barrier 20
Position, finally to grouting material is perfused inside metal bellows 25.
Certainly, to reduce bridge deck width, the setting of block 12 can be cancelled, and setting is cut in prefabricated 20 bottom of anticollision barrier
