Abstract
The utility model relates to a core pile type prestressed concrete light laminated slab, and belongs to the field of building components. The core pile type prestressed concrete light laminated slab is composed of an upper cast-in-place concrete slab and a lower reinforced concrete precast slab, a reinforced concrete bottom layer of the lower reinforced concrete precast slab is composed of a steel reinforcement frame composed of prestressed steel reinforcements and common steel reinforcements and cast concrete, the common transverse steel reinforcements are distributed on the lower layer, the longitudinal steel reinforcements are arranged on the two sides, and the prestressed steel reinforcements are horizontally arranged on the common transverse steel reinforcements. A light filling core layer is arranged on the reinforced concrete bottom layer and is provided with concrete core pile holes longitudinally and transversely distributed at intervals, the closed lower reinforced concrete precast slab is formed through a concrete outer layer on the top face and the periphery of the light filling core layer, the upper cast-in-place concrete slab is cast on the upper surface of the lower reinforced concrete precast slab, and the core pile type prestressed concrete light laminated slab is formed. The laminated slab reduces self weight, improves structural integrality and antiknock characteristics, and can meet requirements of large-span buildings.
Description
Technical field
The light-duty superimposed sheet of a kind of core stake formula prestressed concrete of the utility model, belongs to building unit field.
Background technology
At present in structural engineering, more common precast rc slab, ribbed slab floor, the slab without bond of prestressing of having adopted, still, the span of common precast concrete plank is little, globality is poor, poor seismic behavior; The long construction period of ribbed slab floor and slab without bond of prestressing, complex process, cost are higher, heat preservation and soundproof weak effect.Therefore, all the time, related fields are all endeavouring to develop shock resistance and globality is good, and adapt to compared with the light filling superimposed sheet of long span building.
Utility model content
The purpose of this utility model is to provide a kind of prestressed concrete core stake light filling superimposed sheet, is reducing, under the condition of deadweight, to strengthen superimposed sheet structural bearing capacity and shock resistance, to meet the demand of the larger building of span.
The light-duty superimposed sheet of a kind of core stake formula prestressed concrete of the utility model, formed by top cast in place concrete plate and lower rebar concrete prefabricated board, described lower rebar concrete prefabricated board is by steel concrete bottom, the outer composition of light filling sandwich layer and concrete, described steel concrete bottom is by prestressed reinforcement, the cage of reinforcement of plain bars composition and concreting composition, the plain bars of this cage of reinforcement is made up of transverse reinforcement and longitudinal reinforcement, its transverse reinforcement is distributed in lower floor, longitudinal reinforcement is arranged on both sides, prestress steel is longitudinally arranged on horizontal plain bars, described light filling sandwich layer is arranged on steel concrete bottom, and this light filling sandwich layer has in length and breadth concrete core stake spaced apart, by the concrete skin of this light filling sandwich layer end face and surrounding, forms the lower rebar concrete prefabricated board of sealing, at the scene, in the lower rebar concrete prefabricated board upper surface of sealing, build after the cast in place concrete plate of top, be shaped to the light-duty superimposed sheet of core stake formula prestressed concrete.
Described light filling sandwich layer in length and breadth concrete core stake spaced apart is cylindrical concrete pile.
What the described transverse reinforcement that is arranged on steel concrete bottom was arranged by longitudinal separation is made up of with the encryption transverse reinforcement that is arranged on longitudinal two ends the vertical end of П shape transverse reinforcement.
There is domatic rim the longitudinal both sides of described steel concrete bottom.
The vertical end of П shape of the vertical end of the described П of having shape transverse reinforcement is longitudinally built the reserved syndeton of splicing as superimposed sheet, highlight on steel concrete bottom domatic rim surface.
A kind of prestressed concrete core of the utility model stake light filling superimposed sheet, in plate, light filling piece has reduced plate weight, there are good insulation, sound insulation value, arrangement prestress reinforcing bar in plate, in the time of plate bearing load, plate bottom tension, upper portion pressurized, prevent the cracking of concrete component, improve crack resistance and the rigidity of member, improved the service behaviour of structure.And strengthened the intensity of plate in horizontal concrete core stake, and the holistic resistant behavior of plate is improved, on structural fire protection, play better buffer action simultaneously.Precast concrete superimposed sheet overlap joint platform and adjacent panel and rear pouring concrete were built and were integrated, and have improved structural integrity and overall shock resistance in use later stage.In addition, the utility model part is prefabrication moulding, can suitability for industrialized production, shorten construction period, reduce costs.
