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, the template loss is big, and cost height, precast floor slab do not need on-the-spot formwork, short construction period, cost is low, but prefabricated units lift difficulty from great, member splicing position easily produces the crack, globality is poor, is ZL0322765.2 as the patent No., name is called a kind of patent of floor spiced by steel reinforced concrete, discloses a kind of steel bar concrete prefabricated units, prefabricated units are by plate, rib constitutes, the hole of wearing reinforcing bar is arranged on the rib, and the thickness of this plate is big, and the reinforcing bar effective height that is placed in the Cast-in-place concrete is greatly reduced, influence the bidirectional stress balance of floor, be difficult to form equivalent transverse and longitudinal etc.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, comprises the rectangular base plate of steel bar concrete, the vertically long rib of steel bar concrete, it is characterized in that having laterally run through vertical long rib or and the hole of base plate, hole is to have the non-hole of taking out the permanent hole die component of heart pore-forming.Like this, when vertical rib was arranged on the base plate, the longitudinal rigidity of prefabricated plate for steel concrete with rib was big, and frangibility or distortion do not help construction application; As laterally running through vertical rib or/and during the hole of base plate, reinforcing bar can conveniently be set, and hole does not need the demoulding of loosing core, make simple and convenient, effectively improve hole periphery intensity, after this prefabricated plate for steel concrete with rib is applied in the floor, can make the bidirectional load capacity variance of floor little, improved the stress performance of floor, and the reinforcing bar that exposes can be good at connecting peripheral precast plate and steel bar concrete, and globality is better, thereby has 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.
