Summary of the invention
The purpose of this utility model is that proposition one is novel, holistic resistant behavior good, prestressed concrete bidirectional laminated slab easily of constructing.
The prestressed concrete bidirectional laminated slab that the utility model proposes, by some pieces of precast prestressed concrete stringer boards 1, the horizontal piece 2 that high-strength grout is filled, transverse steel 3 and cast-in-situ steel reinforced concrete overlapping layers 4 through precast prestressed concrete stringer board 1 form, it has been longitudinally arranged presstressed reinforcing steel 5 in every piece of precast prestressed concrete stringer board 1, lateral arrangement has regular reinforcement 6, the prefabricated stringer board 1 longitudinally disposed rib of upper surface 7, on rib 7, horizontal spaced set has several circular openings 8, circular opening 8 on rib 7 is laterally aligned, interspersed transverse steel 3 in each circular opening 8, for making some pieces of precast prestressed concrete stringer boards 1 be connected, circular opening 8 close proximity to rib 7 below, make the transverse steel 3 interted as far as possible close to the concave surface of prefabricated stringer board；Cast-in-situ steel reinforced concrete overlapping layers 4 above some pieces of precast prestressed concrete stringer boards.
In this utility model, precast prestressed concrete stringer board 1 upper surface is matsurface, can use natural matsurface or the impression matsurface meeting existing code requirement.
In this utility model, the two sides of precast prestressed concrete stringer board 1 are inclined-plane, form the horizontal piece 2 of wedge shape between adjacent precast prestressed concrete stringer board 1, fill high-strength grout to prefabricated stringer board concave surface inside the horizontal piece 2 of wedge shape.
In this utility model, reinforced concrete sandwich layer 4 lining is equipped with vertically and horizontally reinforced mesh.
The beneficial effects of the utility model are:
1. on precast prestressed concrete stringer board, longitudinally set rib, can not set during construction or set support less, it is possible to construct in the insulation of prefabricated stringer board concave arrangement and stringing.
2. use transverse steel through each prefabricated stringer board longitudinal rib, it is possible to ensure, by piece Transfer of Shear effectively and moment of flexure, to improve bidirectional stress performance and the bearing capacity of superimposed sheet.
3. circular opening and interspersed transverse steel are below rib, can increase edge joint position effective depth of section, improve the bearing capacity of superimposed sheet, rigidity and cracking resistance so that it is stress performance waters plate close to whole.
Use the horizontal piece of wedge shape between the most prefabricated stringer board, bed die during grouting can be saved, it is achieved superimposed sheet site operation is without template.
5. laterally piece is interior fills high-strength grout, is conducive to improving the cracking resistance of piece.
This utility model use precast prestressed concrete stringer board longitudinally set rib, laterally wear muscle, bidirectional stress laminated floor slab that grouting joint filling, cast-in-place overlapping layers are formed, have that overall performance is good, cracking resistance is excellent, rigidity is big, bearing capacity advantages of higher, also can realize constructing without template, energy-conservation and structure-integrated, there is good economic benefit and environmental benefit, have broad application prospects at building engineering field.
