Description

A kind of cavity former component

The application for the applying date be that September 26, application number in 2003 are 03159684.3, 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, the reinforce in going to the bottom be not owing to stretch into anchoring in the alternative body on every side, thereby, the globality of cavity former component is poor, shock resistance is poor, and particularly under the effect of alternation load or periodicity load, its globality is poorer, simultaneously, stressed and the Force transmission parts of no superstructure in this cavity former component particularly when the cavity former component size is big, shows more obviously.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 characteristics such as good integrity, shock resistance are strong, the mechanical property that can improve superstructure, easy construction.

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, cavity former component is provided with the formation rod member of at least one Cast-in-place concrete cast usefulness or rod member for grid or truss rod shuttering member alternately, constitute Cast-in-place concrete internal-rib die cavity between the opposite face of cavity former component, be provided with at least one spacer draw piece that the cavity former component with opposite face couples together in the internal-rib die cavity, going to the bottom has crossed out reinforce.Like this, 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, anti-seismic performance is strong, and the ability of particularly resisting alternation load or periodicity load action is strong; Simultaneously, because at least two cavity former components alternately, connect to one by a spacer draw piece, form cavity former component in groups, thereby when being applied to cast-in-situ concrete hollow floor, cavity former component is become in groups by single laying to be laid, mutually positioning very convenient, the construction quality that is difficult for inconsistent phenomenon takes place and influences superstructure, and efficiency of construction also improves greatly, thereby reached purpose of the present invention, in addition, cavity former component also has simple in structure, the intensity height, make easily, characteristics such as cost is low are applicable to the hollow building cover of various cast-in-situ reinforced concretes or prestressed reinforced concrete, roof system, body of wall, sole plate and hollow bridges are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention also be described spacer draw piece for and cavity former component between be spacer draw piece between firmly linking.Like this, the spacer draw piece connects as one two or more cavity former components between firmly linking, when it is applied in the cast-in-situ concrete hollow floor, handling, install more convenient.

Feature of the present invention also be described spacer draw piece for cavity former component between for flexibly connect or telescopic be connected between the spacer draw piece.Like this, when cavity former component is applied in the cast-in-situ concrete hollow floor, after cavity former component installs, active interval can be supportted the draw piece dismounting and reclaim the secondary use, reduced the cost of production of cavity former component, simultaneously, behind the dismounting support draw piece, reinforcing bar can be laid in the internal-rib die cavity very easily, and concrete also can pour in the internal-rib die cavity swimmingly.If between the spacer draw piece be telescopic connection between the spacer draw piece, can suitably regulate the width of internal-rib die cavity between the cavity former component when then constructing, to satisfy different designs and actual needs.

Feature of the present invention is that also described spacer draw piece is at least one in rod member, rope, plate, muscle, silk, thin band, piece, the pier.Like this, the variation of support draw piece material and structure can be satisfied the different designs requirement of product, and can be according to different needs, adopts reasonable manner to connect.As adopt web strap material and wood particle as the support draw piece, and being arranged in the internal-rib die cavity, the metal foil band can play a part to draw, and wood particle can play support.

Feature of the present invention also be spacer draw piece between described rod member, plate, piece, pier formula be hollow porous hollow or compound between the spacer draw piece.Like this, can be according to the design needs, hollow or solid or porous of corresponding employing or compound support draw piece rationally solve the reinforcing problem of drawing that supports.
