Specific implementation mode
Referring to figs. 1 to Fig. 5, guardrail grouting connection prefabricated assembling type reinforced concrete side crashproof guardrail of the present invention, including
Prefabricated anticollision barrier 20 and precast main beam 10, precast main beam 10 have the connection reinforcing bar 11 for extending and stretching out, prefabricated anticollision barrier 20
It is constituted by concrete prefabricated and is embedded with longitudinal reinforcement 21, bending resistance reinforcing bar 22, distributing bar 23, stirrup 24 and metal wave in inside
Line pipe 25, longitudinal reinforcement 21 is longitudinally arranged, and metal bellows 25 is gone forward side by side through 20 side part of prefabricated anticollision barrier is embedded in
The structure thicker processing of row part, stirrup 24 are looped around outside metal bellows 25, to improve local pressure, distributing bar 23 and hoop
Muscle 24 is welded to connect to form one, and 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 open top 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 materials.
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, and 13 inside of drip is by construction configuration
Reinforcing bar is simultaneously common prefabricated with precast main beam 10.
Preferably, connection reinforcing bar 11 is divided to stretch into connection reinforcing bar 111 and pre-buried 112 two sections of connection reinforcing bar, precast main beam
10 are embedded with the jointing 14 of top surface and 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, stretches into connection 111 bottom of reinforcing bar and jointing 14 is removable
Formula connection is unloaded, is preferably threaded, two sections of settings of connection reinforcing bar 11, depositing after the completion of precast main beam 10 can be facilitated prefabricated
It puts transport, when site operation, stretches 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 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 13 is moved into 10 end of precast main beam.In 20 bottom surface of prefabricated anticollision barrier and precast main beam 10
Top surface, which is stayed, sets splicing seam, and it is preferably 3mm to be glued seam.
When installation, epoxy resin jelly is uniformly smeared in 10 corresponding top surface of precast main beam first, epoxy resin jelly is thick
Degree is not less than 3mm, and shearing slot 26 is simultaneously aligned by subsequent hoisting prefabricated anticollision barrier 20 with shear connector 15, utilizes prefabricated anticollision barrier
20 dead weight squeezes out epoxy resin jelly with glue groove 27 is gone out, and epoxy resin jelly is formed by curing epoxy glue layer 16.It is prefabricated
20 bottom outer wall of anticollision barrier strikes off the extra epoxy resin of spilling along baste 28 after there is baste 28, epoxy resin jelly to squeeze out
Jelly so that structure is more aesthetically pleasing.
Preferably, being also embedded with pvc pipe 29 inside prefabricated anticollision barrier 20, street lamp electric wire or communications optical cable can be facilitated
The placement of equal wire rods, and mitigate the weight of prefabricated anticollision barrier 20.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula, the technical field those of ordinary skill within the scope of knowledge, can also be before not departing from present inventive concept
Put that various changes can be made.
