Abstract
The invention discloses a ribbed reinforced concrete prefabricated board, comprising a reinforced concrete base plate, a longitudinal rib and prestressed reinforcing steel bars, wherein through holes are drilled at two sides of the longitudinal rib of the reinforced concrete prefabricated board, and grooves are formed at the positions, corresponding to the through holes, of the base plate. A floor slab is formed by assembling a plurality of the reinforced concrete prefabricated boards, the hole-penetrating reinforcing steel bars penetrate through the holes at two sides at the lower part of the longitudinal ribs of the prefabricated boards and are placed on the grooves on the base plates, meanwhile, a plurality of reinforced concrete prefabricated boards are connected, and concrete is poured then for flatness. Because the placement positions of the hole-penetrating reinforcing steel bars are lower, the performance of the hole-penetrating reinforcing steel bars can be used fully, and the grooves on the base plates can be used for enhancing the cementation between the prefabricated boards and the concrete, so that the integral performance of the floor slag is enhanced.
Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of Ribbed Bar concrete prefabricated board.
Background technology:
Ribbed Bar concrete prefabricated structural board (03227765.2) now commonly used is floor spiced.This precast member board with ribbing has hole in the longitudinal rib both sides; When floor spiced; Reinforcing bar is passed the hole of both sides under the prefabricated units longitudinal rib; Connect the polylith precast member for reinforcing bar concrete, fluid concrete in the groove that prefabricated units form makes prefabricated units, wears reinforcing bar at present, integral body is formed in cast-in-situ concrete.This precast floor slab good integrity can be born bidirectional load, does not need on-the-spot formwork, short construction period.But not enough below existing: because the influence of base plate thickness, the distance between perforation reinforcing bar and the base plate bottom surface is bigger, and the performance of perforation reinforcing bar can not get sufficient application.
Summary of the invention:
The object of the present invention is to provide and a kind ofly can make full use of the perforation reinforcement property, from heavy and light, Ribbed Bar concrete prefabricated board that cost is low.
The objective of the invention is to realize like this; This Ribbed Bar concrete prefabricated board; Comprise reinforced concrete floor, longitudinal rib, prestressed reinforcement, have via holes, it is characterized in that on the corresponding base plate of hole fluted in reinforced concrete prefabricated board longitudinal rib both sides.
Floor is assemblied to form by the polylith reinforced concrete prefabricated board, and the perforation reinforcing bar passes the hole of both sides under the precast plate longitudinal rib, is placed on the bottom plate groove, connects the polylith reinforced concrete prefabricated board simultaneously, and concreting is filled and led up again.Because perforation reinforcing bar placement location is lower, can make full use of the performance of perforation reinforcing bar, the groove on the base plate can strengthen precast plate and concrete bonding, has strengthened the overall performance of floor.

The specific embodiment:
With reference to figure 1-Fig. 5, this Ribbed Bar concrete prefabricated board comprises reinforced concrete floor 1, longitudinal rib 2, prestressed reinforcement 3, and 2 times both sides of described steel concrete longitudinal rib have via holes 5, on the corresponding base plate of hole 5 fluted 4.When floor spiced; The polylith reinforced concrete prefabricated board is close to; Wear the hole 5 that reinforcing bar 6 passes 2 times both sides of precast plate longitudinal rib at present, be placed on the bottom plate groove 4, connect the polylith reinforced concrete prefabricated board; Concreting 7 is filled and led up again, makes precast plate, perforation reinforcing bar 6, cast-in-situ concrete 7 form integral body.Because perforation reinforcing bar 6 placement locations are lower, can make full use of the performance of perforation reinforcing bar 6, the groove 4 on the base plate 1 can strengthen precast plate and concrete bonding, has strengthened the overall performance of floor.
