Abstract

The utility model relates to a reinforced concrete prefabricated slab. The utility model is characterized in that both sides of the prefabricated slab have side wings, the inner part of the slab body is provided with longitudinal reinforcements and additional transverse reinforcements, and the surfaces of the side wings are reserved with transverse reinforcements whose ends are hooked. When in masonry, the hooked ends are connected by steel bar hoops, and the surfaces of the side wings are filled with concrete to be a whole.

Description

The reinforced concrete prefabricated board that the limit wing is arranged

The utility model relates to a kind of building reinforced concrete precast plate, particularly a kind of concrete prefabricated board that the limit wing is arranged and dispose transverse reinforcement.

At present, used precast plate in the building construction, it is general that this plate is called unidirectional single reinforcement plate, in building by laying bricks or stones, a small amount of packing material is only arranged between plate and plate, is in no connection status substantially only at the vertical configuration reinforcement of precast plate, and its structural integrity is very poor.I am 95236644 for another example, described in 4 " concrete prefabricated boards that the limit tooth is arranged ", at the dual-side of precast plate the limit tooth is arranged, make its one-tenth as a whole though when building by laying bricks or stones, can in the tooth of limit, insert concrete, but because of no transverse reinforcement, when meeting stronger vibrations (as earthquake), its overall structure is still relatively poor.

Overall structure was strong when the purpose of this utility model provided a kind of building by laying bricks or stones, crack not, non-leakage reinforced concrete prefabricated board.

Except that longitudinal reinforcement is arranged, also dispose transverse reinforcement in the reinforced concrete prefabricated board of the present utility model, the precast plate dual-side has the limit wing, and reserves the connection crotch of transverse reinforcement on the aerofoil of limit.When building by laying bricks or stones, the reinforcing bar on the adjacent edge aerofoil is connected crotch couple together, on the aerofoil of limit, insert concrete enclosing plate seam then with stirrup.Like this, become cast-in-place plate after can making monolithic concrete prefabricated board assembling, reach the not purpose of crackle, antiseep.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model assembling schematic diagram.

Fig. 3 is that the utility model I-I is to sectional view.

1, prefabricated plate body 2, the limit wing 3, longitudinal reinforcement

4, transverse reinforcement 5, connection crotch 6, stirrup

The utility model is described in further detail below in conjunction with accompanying drawing.

As Fig. 1, reinforced concrete prefabricated board 1 shown in Figure 3, at its dual-side the limit wing 2 is arranged, except that longitudinal reinforcement 3 is arranged, also disposes transverse reinforcement 4 in the plate, and on 2 on the limit wing, reserve the connection crotch 5 of transverse reinforcement 4.When building flooring by laying bricks or stones, as shown in Figure 2, the corresponding connection crotch 5 usefulness stirrups 6 on 2 on the adjacent edge wing are coupled together, then with concrete enclosing plate seam, do coagulate after, all transverse reinforcements all are connected to each other between plate and plate.

Can reach the effect of cast-in-place integral slab after the precast plate assembling of the present utility model, not crack, non-leakage.

Claims

1, a kind of building reinforced concrete precast plate is furnished with reinforcing bar in the plate, it is characterized in that there is the limit wing its precast plate both sides, be furnished with transverse reinforcement, and reserve transverse reinforcement on the aerofoil of limit in the plate.

2, reinforced concrete prefabricated board according to claim 2 is characterized in that the transverse reinforcement end that reserves on the aerofoil of limit is a crotch shape.
