Abstract
The present invention discloses a prestressed reinforced concrete precast member plate with ribs, which comprises a reinforced concrete bottom plate and reinforced concrete longitudinal ribs; both sides of the underside of each longitudinal rib of the reinforced concrete precast member plate are provided with long strip-shaped holes or long arc-shaped holes. The eccentric distance of the prestressed reinforced concrete precast member plate with ribs is the distance from prestressed reinforcements to the centroid of the cross section of the precast member plate; the distance divided by the long strip-shaped holes or the long arc-shaped holes between the bottom plate and the longitudinal ribs at the sites of the holes is long, so that the precast member plate has a smaller inverted arch value and a level plate bottom surface, and steel reinforcements are conveniently arranged in place.
Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of prestressed reinforced concrete precast member board with ribbing.
Background technology:
At present, floor spiced by steel reinforced concrete can bear bidirectional load, and good integrity does not need on-the-spot formwork, and cost is low, and lifting, transportation are easily.Floor spiced precast member for reinforcing bar concrete is used Ribbed Bar concrete prefabricated structural board (seeing 03227765.2 patent application) usually, both sides have hole under the precast member for reinforcing bar concrete longitudinal rib, now wear the hole that reinforcing bar passes both sides under the prefabricated units longitudinal rib, connect the polylith reinforced concrete prefabricated structural board, make the crisscross layout of reinforcing bar, floor spicedly can bear bidirectional load.But because the hole of both sides is worn reinforcing bar usefulness usually under the longitudinal rib, it is little that open in the aperture, this precast member board is had the following disadvantages: 1, this prefabricated units strip prestressing force makes on the prestressed reinforced concrete precast member board with ribbing and produces eccentric throw, under the prestressing force effect, precast member board produces antiarch, make out-of-flatness at the bottom of the plate, eccentric throw is big, and the antiarch value is big; Eccentric throw is little, and the antiarch value is just little, and small holes can not reduce the antiarch value; 2, the aperture is opened for a short time, and it is also inconvenient now to wear reinforcing bar.
Summary of the invention:
The object of the present invention is to provide a kind ofly can reduce the antiarch value, make at the bottom of the plate smoothly, now wear reinforcing bar prestressed reinforced concrete precast member board also with ribbing easily.
The object of the present invention is achieved like this, this prestressed reinforced concrete precast member board with ribbing, comprise reinforced concrete floor, steel concrete longitudinal rib, both sides have strip or long arc shape hole under the reinforced concrete prefabricated structural board longitudinal rib, ratio L/H 〉=1.5 of described strip or long arc shape hole bottom side length L and the high H of hole.
Because the eccentric throw of prestressed reinforced concrete precast member board with ribbing is the distance of prestressed reinforcement to the precast member board cross section centre of form, the distance that strip or long arc shape hole separate base plate and longitudinal rib at the hole place, reduced the eccentric throw at strip hole place of precast member board, precast member board antiarch value is reduced, also just smooth at the bottom of the plate, it is also convenient now to wear reinforcing bar.

The specific embodiment:
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, this prestressed reinforced concrete precast member board with ribbing of Fig. 8, comprise reinforced concrete floor 1, steel concrete longitudinal rib 2, have strip hole 3 or long arc shape hole 4 in 2 times both sides of reinforced concrete prefabricated structural board longitudinal rib, ratio L/H 〉=1.5 of described strip hole 3 or long arc shape hole 4 bottom side length L and the high H of hole.
The eccentric throw of prestressed reinforced concrete precast member board with ribbing is the distance of prestressed reinforcement 5 to the precast member board cross section centre of form, strip hole 3 or long arc shape hole 4 are long with the distance L that longitudinal rib 2 separates with base plate 1 at hole 3,4 places, reduced the eccentric throw of precast member board, strip hole 3 or long arc shape hole 4 have reduced the antiarch value like this, make at the bottom of the plate 1 smoothly, it is also convenient now to wear reinforcing bar.Be used for when floor spiced, the polylith precast member board is close to, now wear and add prestressing force after reinforcing bar passes strip hole 3 or long arc shape hole 4, concreting again in the groove that adjacent both sides of the chest form makes the polylith precast member board, now wears reinforcing bar, cast-in-situ concrete is combined into integral body.
