Abstract
The utility model discloses a reinforced concrete hollow prefabricated member board which comprises a reinforced concrete board body; projecting blocks are provided on the bottoms on both sides of the reinforced concrete board body; a connecting reinforcement is provided on the lower parts on both sides of the reinforced concrete board body close to the surface of the projecting block; when a floor board is assembled, a hollow prefabricated member board is positioned on a supporting base, which forms a groove shape cavity on the splicing point of the adjacent prefabricated member boards; the connecting reinforcement which is provided on the lower parts on both sides of the reinforced concrete board body close to the surface of the projecting block extends into the groove shape cavity and is mutually connected so as to directly cover on the seaming of the adjacent two board bodies; and then the groove shape cavity is filled by casting the concrete so as to cause the adjacent two board bodies, the connecting reinforcement and the cast-in-place concrete to form a whole; the splicing point of the adjacent prefabricated member boards are uneasy to crack, the cracking resistance is fine, and the leakage-proof property is strong; the connecting force between adjacent prefabricated member boards is also strong, and the integrality of the assembling floor board is fine.
Description
Technical field:
The utility model relates to the realm of building construction, specifically refers to a kind of hollow prefabricated steel bar reinforced concrete boards.
Background technology:
Hollow prefabricated steel bar reinforced concrete boards commonly used now is a strip, the centre has through hole, it is low that this hollow prefabricated plate has cost, convenient construction, make advantages such as easy, when floor spiced, earlier hollow prefabricated plate is shelved on wall or the beam, hang the mould concrete cementation of fissures in splicing place of contiguous prefabricated panels then, form cassette ceiling, but this hollow prefabricated plate is floor spiced, and following deficiency is arranged: the mould concrete cementation of fissures, complex procedures are hung in its contiguous prefabricated panels splicing place, waste time and energy, splicing place is easy to crack, and crack resistance is poor, and seam crossing easily produces seepage; A little less than the connection power, floor spiced globality is poor between the contiguous prefabricated panels.
Summary of the invention:
The purpose of this utility model is to provide splicing place of a kind of contiguous prefabricated panels need not hang the mould cementation of fissures, time saving and energy saving, can reach not easy to crack, and crack resistance is good, is difficult for producing seepage; Connection power is strong between the contiguous prefabricated panels, the hollow prefabricated steel bar reinforced concrete boards of floor spiced good integrity.
The purpose of this utility model is achieved like this, this hollow prefabricated steel bar reinforced concrete boards, comprise reinforced concrete slab, described reinforced concrete slab two side bottoms are provided with the protrusion piece, and described reinforced concrete slab two side lower parts are pressed close to protrude the piece surface and are provided with connecting reinforcement.
Owing to be provided with protrusion piece down at described reinforced concrete slab two side bottoms.Described reinforced concrete slab two side lower parts are pressed close to protrude the piece surface and are provided with connecting reinforcement.When floor spiced, earlier hollow prefabricated plate is shelved on the bearing, forms slotted cavities in adjacent two precast member board splicings place, adjacent two protrude piece has been close to the effect of making template, can be in slotted cavities direct concreting, splicing place need not hung mould, not only saves time but also laborsaving; Adjacent two base plates, two side lower parts are pressed close to protrude the connecting reinforcement that the piece surface is provided with and are stretched in the slotted cavities, reach mutually and connect, directly cover on the seam of adjacent two plate bodys, strengthened the crack resistance of seam crossing, concreting is filled and led up slotted cavities again, makes adjacent two plate bodys, connecting reinforcement, the cast-in-place concrete of building form integral body, and the cast-in-place concrete thickness of building is greater than protruding piece thickness, splicing place of contiguous prefabricated panels is not easy to crack, and crack resistance is good, anti-leakage is strong; Connection power is also strong between the contiguous prefabricated panels, floor spiced good integrity.

Fig. 1 hollow prefabricated steel bar reinforced concrete boards structural representation
Another embodiment of Fig. 2 hollow prefabricated steel bar reinforced concrete boards
The hollow prefabricated plate splicing construction of Fig. 3 schematic diagram
Hollow prefabricated another embodiment of plate splicing construction of Fig. 4
The specific embodiment:
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, this hollow prefabricated steel bar reinforced concrete boards, comprise reinforced concrete slab 2, the centre has through hole 1, and described reinforced concrete slab 2 both sides are provided with protrudes piece 3, protrudes width L 〉=3.5 centimetre of piece 3, can the lifting plate effect, seam about staggering again, 2 liang of side lower parts of plate body are pressed close to protrude piece 3 surfaces and are provided with connecting reinforcement 4, and 2 liang of upper lateral parts of plate body are provided with connecting reinforcement 5.
When floor spiced, earlier hollow prefabricated plate body 2 is shelved on the bearing, form slotted cavities 8 in contiguous prefabricated member plate body 2 splicings place, adjacent two protrude piece 3 has been close to the effect of making template, 2 liang of side lower parts of adjacent two plate bodys are pressed close to protrude the connecting reinforcement 4 that piece 3 surfaces are provided with and are stretched in the slotted cavities 8, reach mutually and connect, directly cover on the seam 7 of adjacent two plate bodys, strengthened the crack resistance at seam 7 places, connecting reinforcement 4,5, strengthened floor spiced crack resistance, anti-leakage, globality, concreting 6 is filled and led up slotted cavities 8 again, forms floor spiced.
The utility model also can be used for the hollowcore slab of bridge.
