Description
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(2) background technology
At present, in the prior art, be used for the thin-walled Cavity structural member of cast-in-situ reinforcing steel bar concrete hollow slab, paper tube, plastic pipe, metal hollow pipe, horniness thin-walled tube, thin-walled putamina member, core etc. are arranged, these thin-walled Cavity structural members mainly consider to find time concrete, alleviate floor weight.It as the patent No. " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder " utility model patent of 99249755.8, it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, horniness thin-walled tube cross section and plug shape can be circle, square, trapezoidal or other is special-shaped, this kind fiber reinforcement type thin wall cylinder, its preparation method is to adopt Wrapping formed method, after body is Wrapping formed, will cover the shutoff mouth of pipe, be finished product with the single or multiple lift fiber stringing outsourcing of cement paste.Metallic coil adopts metal sheet roof covering spiral die mould flanging interlock, forms the metal bellows of single ripple, double wave or many ripples, by the real size cutting, coats the mouth of pipe with plastic sheeting then.This class pipe has advantages such as self intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.The patent No. is " Cavity structural member " utility model patent of 932063101.1, it by upper base, go to the bottom, sidewall is formed all around, and constitutes totally-enclosed empty stomach polyhedral structure, is provided with ribs in the formwork.More than all kinds of thin-walled Cavity structural members because weight is big, cost height, thereby apply and be subjected to certain restriction.For this reason, develop a kind of novel cast-in-place concrete cored for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-place concrete coredly, have easy construction, efficient height, be easy to guarantee characteristics such as cast-in-place concrete cored construction quality.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, Cavity structural member, Cavity structural member is wrapped up in and is contained in the steel bar concrete, and Cavity structural member alternately, be the cast-in-situ reinforced concrete rib each other, be the cast-in-situ reinforced concrete upper plate on it, it is the cast-in-situ reinforced concrete lower plate down, and Cavity structural member is made up of evacuated mould, it is characterized in that also including the structure base plate, structure base plate and evacuated mould are connected to form polyhedral structure, and evacuated mould is the blowing part, and charging connector is arranged on it.Like this, because evacuated mould is the blowing part, thereby cast-in-place concrete cored, have easy construction, efficient height, be easy to guarantee cast-in-place concrete cored construction quality, thereby reached purpose of the present invention; Be applicable to the structure of various Cast-in-place Concrete Building Floor, roof system, body of wall, sole plate and road and bridge engineering, be specially adapted to hollow arch without beam.
Feature of the present invention is that also described evacuated mould is provided with reinforcing rib.Can further improve the strength and stiffness of Cavity structural member like this, stressed preferably and power transmission.The shape of reinforcing rib, highly, thickness can be by the actual needs adjustment.
Feature of the present invention is that also described evacuated mould is provided with groove.Like this, the Cast-in-place concrete reinforcing rib structure can be formed, the mechanical property of superstructure can be improved at the groove position.
Feature of the present invention is that also the surface of described evacuated mould is the rough surface of waveform or zigzag or other shape.Like this, the variation of evacuated mould surface configuration is convenient to construction and is selected for use with designing unit; Simultaneously, can improve the globality of superstructure.
When feature of the present invention also was to be full of gas in the described evacuated mould, it was shaped as tubulose or box-like.Tubulose is the pipe of pipe, square tube, elliptical tube or other shape, and box-like is the box of cuboid, square, circle side's body, rib body or other shape.Like this, being convenient to construction selects for use with designing unit.
Feature of the present invention is that also described structure base plate is the base plate that cement mortar or cement concrete include reinforce.Reinforce is that reinforcing bar, prestressed reinforcement, steel wire, steel fibre, fibre, steel mesh reinforcement, gauze wire cloth, fleece, nonwoven are gluingly arranged net, at least a in the metal tape, braid over braid, strap.Like this, the structure base plate contains reinforce, and then the good integrity of Cavity structural member, intensity and rigidity are big.Simultaneously, the kind of reinforce is many, helps reducing material cost, to satisfy the needs of various different occasions.
Feature of the present invention also is on the described structure base plate reinforcing rib is arranged, and perhaps also has reinforce to expose on the structure base plate.Can further improve the strength and stiffness of structure base plate like this, stressed preferably and power transmission.Simultaneously, the structure base plate exposes reinforce, can prevent cast-in-place and prefabricated combination interface cracking effectively.
