Description

A kind of cast-in-place concrete cored
The application for the applying date be that June 6, application number in 2005 are 200510074455.9, name is called the dividing an application of application for a patent for invention of " a kind of cast-in-place concrete cored ".
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(2) background technology
The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, this floor structure has advantages such as speed of application is fast, cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, be unfavorable for antidetonation, and slit cracking, infiltration often occur, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for Cast-in-place concrete floor (hollow, solid).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased expense, and the speed of application that slowed down, prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib floor structure " utility model patent, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is horizontal positioned at interval, on prefabricated plate, be fixed with formwork, formwork comprises upper plate and side plate on every side, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connect as one with dark rib, this kind floor structure no longer needs to use in a large number template, accelerate speed of application, shortened the duration, thereby reduced cost.But when the shuttering member in this floor structure is produced, make inconveniently, production efficiency is low, is not easy to streamline production, the cost of production height, and corresponding cast-in-place concrete cored construction cost height, thereby, 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 cored, the cavity former component that its hollow pore-forming is used has the characteristics such as easy, that production efficiency is high, cost is low of making, corresponding cast-in-place concrete cored construction cost is low, simultaneously, have also that simple in structure, resistance to deformation, anti-vibration performance are good, characteristics such as easy construction, speed of application are fast.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, cavity former component, cavity former component is wrapped up in and is contained in the steel bar concrete, cavity former component is the cast-in-situ reinforced concrete rib each other, cavity former component comprises upper plate, sidewall on every side, lower plate, upper plate, sidewall on every side, lower plate surrounds the enclosed cavity shuttering member, the upper plate that it is characterized in that described enclosed cavity shuttering member, sidewall on every side, lower plate is made of assembly, assembly is a slice precast slab and the cast-in-place plate composition of a slice bonded and precast plate at least at least, the upper surface of upper plate wrap up in be contained in cast-in-place concrete cored in or the soffit of lower plate wrap up in be contained in cast-in-place concrete cored in or the soffit of the upper surface of upper plate and lower plate all wrap up in be contained in cast-in-place concrete cored in, shuttering member is by prefabricated upper plate, sidewall around prefabricated, cast-in-place lower plate is put together, every precast slab is extended with at least one connector, and contiguous prefabricated plate is interconnected by connector.Like this, be interconnected to form cavity former component by connector between prefabricated upper plate, prefabricated sidewall on every side and the cast-in-place lower plate, have that production technology is simple, speed of production is fast, efficient is high, can realize the mechanization production in enormous quantities, thereby reduced the cost of production of cavity former component effectively, correspondingly reduced cast-in-place concrete cored construction cost.Since cavity former component by a slice precast slab at least and at least the cast-in-place plate of a slice bonded and precast plate form, precast slab can be made in advance, precast slab and cast-in-place plate can bond and form integral body, thereby, the making of cavity former component is easy, production efficiency is high, cost is low, and good integrity; Simultaneously, precast slab and cast-in-place plate bonding, make the amalgamation position of cavity former component plate be difficult for cracking destruction, in addition, cast-in-place concrete coredly have also that simple in structure, resistance to deformation, anti-vibration performance are good, characteristics such as easy construction, speed of application are fast, thereby reached purpose of the present invention, be applicable to that hollow building cover, roof system, body of wall, sole plate and the hollow bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete used, be particularly useful for hollow arch without beam and use.
Feature of the present invention also is to have between the described precast slab connector to connect.Like this, it is very convenient, simple that cavity former component is manufactured, and connects because of connector is arranged between the precast slab, transporting, depositing in the process and can supportingly in bundle, can not cause because of disappearance causes the infull situation of cavity former component, help reducing cast-in-place concrete cored construction cost.
