Description
(1) technical field
The present invention relates to a kind of laminated reverse T-shaped board.
(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 laminated reverse T-shaped board for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of laminated reverse T-shaped board, 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 base plate, vertical rib, vertical rib is arranged on the base plate, it is characterized in that having at least one board slot to be lower than the plate end, board slot gos deep into the laterally heavy muscle structure board slot that base plate is used for the transversary steel bar stress, and vertical muscle that sets in advance and transversary steel bar stress are provided with near intersecting.Like this, when described laminated reverse T-shaped board is applied in the floor, Cast-in-place concrete pours in the groove, can be fully and the superimposed build-in of groove, make its participation structure power transmission better, thereby reached purpose of the present invention, be applicable to that superimposed superstructure, roof system, body of wall, sole plate and the bridge of cast-in-situ reinforced concrete or prestressed reinforced concrete uses, be particularly useful for superimposed superstructure and use.
