Description
(1) technical field
The present invention relates to a kind of prefabricated plate for steel concrete with rib.
(2) background technology
At present, the reinforced concrete floor of domestic employing has cast-in-situ floor and precast floor slab, the cast-in-situ floor good integrity, but need on-the-spot formwork, concreting then, the construction period difficulty is big, and the template loss is big, the cost height, precast floor slab does not need on-the-spot formwork, short construction period, cost is low, but prefabricated units are from great, the lifting difficulty, member splicing position easily produces the crack, and globality is poor, is ZL0322765.2 as the patent No., name is called a kind of patent of floor spiced by steel reinforced concrete, a kind of steel bar concrete prefabricated units are disclosed, prefabricated units are by plate, rib constitutes, and the hole of wearing reinforcing bar is arranged on the rib, and the thickness of this plate is big, the reinforcing bar effective height that is placed in the Cast-in-place concrete is greatly reduced, and ftractureing easily in adjacent panels amalgamation position, has influenced the stability of floor.Therefore, develop a kind of novel prefabricated plate for steel concrete with rib for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of prefabricated plate for steel concrete with rib, have the member section of reducing size, reduce formwork, save characteristics such as material, easy construction, cycle weak point, globality, crack resistance and shock resistance are good.
Solution of the present invention is on the basis of existing technology, comprise the vertically long rib of rectangular base plate of steel bar concrete and steel bar concrete, it is characterized in that vertical groove being arranged or/and raised line on one of vertical long rib or two rib sides, on the rectangular base plate horizontal groove is arranged or/and raised line, vertically the longitudinal reinforcement in the longitudinal reinforcement of long rib and the rectangular base plate be arranged in parallel.Like this, on one of vertical long rib or two rib sides, vertical groove is arranged or/and raised line, horizontal groove is arranged or/and raised line on the rectangular base plate, when vertically the longitudinal reinforcement of long rib and the longitudinal reinforcement in the rectangular base plate be arranged in parallel, groove is or/and after the setting of raised line makes precast plate be applied in the floor, can be fully and Cast-in-place concrete combine, make it not easy to crack, vertically the longitudinal reinforcement in the longitudinal reinforcement of long rib and the rectangular base plate be arranged in parallel and then makes the vertically long rib of rectangular base plate and steel bar concrete can cooperative bearing, improve the overall performance and the weight bearing power of precast plate, make precast plate not fragile in the production application process, effectively reduce the wastage, improve security performance, thereby reached purpose of the present invention, be applicable to the superimposed superstructure of cast-in-situ reinforced concrete or prestressed reinforced concrete, roof system, body of wall, sole plate and bridge use, and are particularly useful for superimposed superstructure and use.
