Description

A kind of cavity former component

The application for the applying date be that September 26, application number in 2003 are 03143333.2, name is called the dividing an application of application for a patent for invention of " a kind of cavity former component ".

(1) technical field

The present invention relates to a kind of cavity former component.

(2) background technology

At present, cast-in-situ concrete hollow floor is to use wider floor structural form, and the lightening permanent loose tool of filling in it has various hollow sections and box, and box has hollow or solid.Is that ZL99249798.1, name are called " filling reinforced concrete fiber reinforcement type thin-wall member " utility model patent as the applicant in the patent No. of application on November 29th, 1999, it discloses a kind of thin-wall mould-shell member, comprise upper plate, on every side sidewall, go to the bottom, upper plate, on every side sidewall, going to the bottom surrounds the polyhedron cavity, upper plate, on every side sidewall, going to the bottom contains fabric reinforcement.And for example the applicant in the application number of November 23 calendar year 2001 application be 01140106.0, publication number is that CN1356442, name are called " a kind of mould with cavity structure for casting reinforced concrete floor slab " application for a patent for invention, it comprises " upper plate, on every side sidewall, go to the bottom; upper plate, on every side sidewall, going to the bottom surrounds the polyhedron cavity former component; upper plate, sidewall, the reinforces such as containing fiber or gauze wire cloth of going to the bottom on every side, characteristics such as that this cavity former component has is in light weight, intensity is high, simple in structure, convenient construction and transport.But, the upper plate of this class cavity former component, sidewall on every side, reinforce in going to the bottom is not owing to stretch into anchoring in the alternative body, thereby, the globality of cavity former component is poor, vibration resistance is poor, particularly under the effect of alternation load or periodicity load, its globality is poorer, simultaneously, when cast-in-situ concrete hollow floor is constructed, cavity former component laying location each other is inconvenient, easily produce displacement or inconsistent phenomenon, occur on the inconsistent and cavity former component of Cast-in-place concrete rib thickness between the cavity former component or following Cast-in-place concrete upper plate or Cast-in-place concrete lower plate variable thickness such as cause at phenomenon, thereby influence the total quality and the stress performance of cast-in-situ concrete hollow floor, increase difficulty of construction, therefore, develop a kind of novel cavity former component for being badly in need of.

(3) summary of the invention

The object of the present invention is to provide a kind of cavity former component, have good integrity, vibration resistance strong, lay the location convenient, be difficult for the characteristics such as construction quality that produce displacement or dislocation, be easy to guarantee superstructure.

Solution of the present invention is on the basis of existing technology, comprise upper plate, sidewall on every side, go to the bottom, upper plate, sidewall on every side, go to the bottom and surround the polyhedron cavity former component, upper plate, sidewall on every side, go to the bottom and contain reinforce, it is characterized in that at upper plate, sidewall on every side, there is reinforce to stretch into the interior also anchoring of alternative body wherein at least a body of going to the bottom, the external surface of polyhedron cavity former component is provided with at least one connector, the protruding bridging piece that has of going to the bottom, a plurality of cavity former components connect and compose assembly in groups by bridging piece, and the spacing between the cavity former component constitutes the internal-rib die cavity.Like this, when cavity former component was applied in the cast-in-situ concrete hollow floor, outwardly directed bridging piece can replace construction formwork, reduced the template loss, reduced material cost, can save the template installation procedure simultaneously, accelerated speed of application, improved efficiency of construction.Because upper plate, on every side have reinforce to stretch in the alternative body in sidewall, at least a body of going to the bottom and anchoring wherein, thereby, the good integrity of cavity former component, resistance to shock is strong, particularly resists the alternation load or periodically the ability of load action is strong; Simultaneously, when cast-in-situ concrete hollow floor is constructed, be connected to each other by connector between cavity former component and the cavity former component, thereby cavity former component is laid easy to connect, can not produce displacement or dislocation each other, construction easily, the Cast-in-place concrete rib width that can not occur between cavity former component and the cavity former component is inconsistent, phenomenons such as Cast-in-place concrete upper plate and lower plate variable thickness cause, guaranteed the total quality of cast-in-situ concrete hollow floor, satisfied the stress performance requirement of superstructure, reduced construction cost, thereby reached purpose of the present invention, be applicable to the hollow building cover of various cast-in-situ reinforced concretes or prestressed reinforced concrete, roof system, body of wall, sole plate or hollow bridges are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention is that also described connector is arranged on the sidewall on every side of polyhedron cavity former component.Like this, connector is arranged on the peripheral side of cavity former component, connects very conveniently, greatly reduces difficulty of construction, helps improving speed of application.
