Specific embodiment
Referring to figs. 1 to Fig. 5, steel plate of the present invention connects prefabricated assembling type reinforced concrete side crashproof guardrail, including prefabricated
Anticollision barrier 20 and precast main beam 10, prefabricated anticollision barrier 20 are constituted by concrete prefabricated and are embedded with longitudinal reinforcement in inside
21, bending resistance reinforcing bar 22, guardrail connection reinforcing bar 23 and angle steel 24, angle steel 24 are located at the prefabricated 20 bottom end face Ying Zhuan of anticollision barrier, angle
The end face outside of steel 24 is exposed outside, and longitudinal reinforcement 21 is longitudinally arranged, and bending resistance reinforcing bar 22 is in prefabricated 20 outside bottom of anticollision barrier
It is bent at 21 position of longitudinal reinforcement in portion, guardrail connects wherein one end of reinforcing bar 23 in the vertical of prefabricated 20 exterior bottom of anticollision barrier
It is bent to 21 position of reinforcing bar, and bending is welded with angle steel 24 at 21 position of longitudinal reinforcement of prefabricated 20 inside bottom of anticollision barrier
It connects in succession, other end continues to protrude into inside prefabricated anticollision barrier 20, it is preferable that guardrail connects reinforcing bar 23, bending resistance reinforcing bar
Two-sided welding connection is carried out by auxiliary bar between 22 and angle steel 24.Of course, it is possible to cancel guardrail connection reinforcing bar 23, resist at this time
Bar bending 22 is welded around a circle arrangement and in bending place and angle steel 24；Meanwhile for convenience of element precast, angle steel 24 can be used
Thicker steel plate replacement, at this point it is possible to be not provided with auxiliary bar.
Precast main beam 10 is pre-buried to have embedded bar 11 and pre-embedded steel slab 12, and embedded bar 11 is embedded in precast main beam completely
Inside 10, and for guarantee anchorage length by it to two lateral bends, pre-embedded steel slab 12 is located at 10 top surface of precast main beam.
When installation, mortar bed 30 is arranged in corresponding position first above precast main beam 10, to guarantee that mortar bed 30 has
Enough placement spaces, pre-embedded steel slab 12 protrude 10 certain altitude of precast main beam, then lift the prefabricated anticollision barrier 20, and
Diagonal steel 24 is welded to connect with pre-embedded steel slab 12, and prefabricated anticollision barrier 20 is connected with precast main beam 10.
Wherein, in order to reduce the dosage of angle steel 24 Yu pre-embedded steel slab 12, while anticollision barrier impact resistance is improved, lifted
It is preceding that in angle steel 24, groove is set, it is welded between angle steel 24 and pre-embedded steel slab 12 using groove welding.In addition, pre-embedded steel slab 12 and angle steel
