Abstract
The utility model discloses a rib steel reinforcement concrete prefabricated part plate, comprising a reinforced concrete bottom plate and a reinforced concrete longitudinal rib; through holes are arranged at two sides of a longitudinal rib of the rib steel reinforcement concrete prefabricated part plate, and a bump is arranged on the bottom plate. A floor plate is formed by splicing a plurality of reinforced concrete prefabricated part plates, a reinforcing steel bar penetrates through the through holes at two sides of the longitudinal rib to connect a plurality of reinforced concrete prefabricated part plates, and then concrete is poured off to fill and level up, and the bump on the bottom plate enhances edge jointing and improves the anti-cracking performance of the floor plate; the lateral anti-bending capacity is improved and lateral reinforcing steel bars are saved.
Description
Technical field:
The utility model relates to the realm of building construction, specifically refers to a kind of Ribbed Bar concrete prefabricated structural 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, now wears reinforcing bar, 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 have the following disadvantages: 1, along with variations in temperature, concrete shrinkage, the local temperature shrinkage crack that easily produces of prefabricated units seam crossing, edge joint position intensity is low; 2, this floor spiced, transverse reinforcement is arranged on the hole of both sides under the prefabricated units longitudinal rib, is positioned at prefabricated units base plate top, and laterally effective height is little, and anti-bending strength is poor, needs a large amount of transverse reinforcements of configuration to improve horizontal anti-bending strength, takes reinforcing bar, the cost height.
Summary of the invention:
The purpose of this utility model is to provide a kind of edge joint position intensity height, and laterally anti-bending strength is good, province's reinforcing bar, the Ribbed Bar concrete prefabricated structural board that cost is low.
The purpose of this utility model is achieved like this, and this Ribbed Bar concrete prefabricated structural board comprises reinforced concrete floor, steel concrete longitudinal rib, has via holes in reinforced concrete prefabricated structural board longitudinal rib both sides, and base plate is provided with projection.
Because this Ribbed Bar concrete prefabricated structural board base plate is provided with projection, when floor spiced, the projection of adjacent two prefabricated units overlaps mutually, has strengthened piece, improves the floor cracking resistance; The setting of projection has increased horizontal effective height simultaneously, improves horizontal anti-bending strength, has improved the horizontal bending resistance of floor, saves transverse reinforcement, and consumptive material is few, and cost is low.

The specific embodiment:
With reference to figure 1-Fig. 5, this Ribbed Bar concrete prefabricated structural board comprises reinforced concrete floor 1, longitudinal rib 2, and 2 times both sides of described steel concrete longitudinal rib have via holes 4, and base plate 1 is provided with projection 3.When floor spiced, the polylith reinforced concrete prefabricated structural board is close to, now wear the hole 4 that reinforcing bar 5 passes 2 times both sides of prefabricated units longitudinal rib, connect the polylith precast member for reinforcing bar concrete, at adjacent precast member for reinforcing bar concrete seam crossing 6 configurable broken line shape reinforcing bars 7, prevent that junction 6 from producing the crack, concreting 8 is filled and led up again, makes prefabricated units, reinforcing bar 5, broken line shape reinforcing bar 7, cast-in-situ concrete 8 form integral body.Projection 3 has been strengthened piece 6, improves the floor cracking resistance; Improve the horizontal bending resistance of floor simultaneously, saved transverse reinforcement.
