Abstract
The utility model discloses a reinforced concrete prefabricated component plate with a rib, which comprises a bottom plate, a longitudinally rib, a reinforced steel bar, a steel plate and bolts. Holes are arranged on two sides of the reinforced concrete prefabricated component plate, one ruler groove or a plurality of ruler grooves are arranged on two sides of the bottom plate, and the bolts are preliminarily buried on the ruler grooves. A building board consists of a plurality of the reinforced concrete prefabricated component plates by splicing, a steel plate with a hole is placed at the ruler groove positions of every two adjacent prefabricated component plates and anchored on the bottom plates of two prefabricated components by the aid of the bolts, the transverse reinforced steel bar penetrates through the holes below the longitudinal ribs of the prefabricated components to be connected the reinforced concrete prefabricated components, and concrete is further filled for flattening by means of pouring. The steel plate at the ruler groove positions reinforces abutted seams, improves cracking resistance performance and integrity of the building board, simultaneously enhances transverse bending resistance capacity of the building board, and saves transverse reinforced steel bars.
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.
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, economizes the Ribbed Bar concrete prefabricated structural board of reinforcing bar.
The purpose of this utility model is achieved like this, this Ribbed Bar concrete prefabricated structural board, comprise base plate, longitudinal rib, reinforcing bar, steel plate, bolt, have via holes, it is characterized in that there are one or more chi grooves the base plate both sides in reinforced concrete prefabricated structural board longitudinal rib both sides.
Feature of the present utility model also is to be embedded with bolt on the chi groove of described Ribbed Bar concrete prefabricated structural board.
Feature of the present utility model is that also the steel plate that has hole in the described Ribbed Bar concrete prefabricated structural board is placed on the chi groove of adjacent two precast member boards, and bolt passes the steel plate hole.
Because there are one or more chi grooves these Ribbed Bar concrete prefabricated structural board base plate both sides, be embedded with bolt on the chi groove, when floor spiced, a steel plate that has hole is placed at chi groove place at adjacent two prefabricated units, use bolt anchoring on two adjacent prefabricated units steel plate, strengthen piece, improved floor cracking resistance and globality; The anchoring of chi groove place steel plate has increased the floor lateral stiffness simultaneously, has improved the horizontal bending resistance of floor, has saved transverse reinforcement.

The specific embodiment:
With reference to figure 1-Fig. 8, this Ribbed Bar concrete prefabricated structural board, comprise reinforced concrete floor 1, longitudinal rib 2, steel plate 6,2 times both sides of described steel concrete longitudinal rib have via holes 3, base plate 1 both sides are respectively arranged with one or more chi groove chi grooves 4, be embedded with bolt 5 on the chi groove 4, the steel plate 6 that has hole 7 is placed on the chi groove 4 of adjacent two precast member boards, and bolt 5 passes steel plate hole 7.
When floor spiced, the polylith reinforced concrete prefabricated structural board is close to, steel plate 6 is placed at chi groove place at adjacent two prefabricated units, hole 7 is arranged on the steel plate 6, make bolt 5 pass hole 7, steel plate 6 usefulness bolts 5 and nut 8 are anchored on the base plate of two prefabricated units, now wear the hole 3 that reinforcing bar 10 passes 2 times both sides of prefabricated units longitudinal rib, connect the polylith precast member for reinforcing bar concrete, concreting 9 is filled and led up again, makes prefabricated units, reinforcing bar 10, steel plate 6, cast-in-situ concrete 9 form integral body.Steel plate 6 has been strengthened piece 11, has improved floor crack resistance and globality; Improve the horizontal bending resistance of floor simultaneously, saved transverse reinforcement.
