Description

A kind of cavity former component

The application for the applying date be that September 26, application number in 2003 are 200610084356.3, name is called the dividing an application of application for a patent for invention of " a kind of cavity former component (1666) ".

(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, vibration resistance is poor, particularly under the effect of alternation load or periodicity load, its globality is poorer, therefore, develops 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, vibration resistance be strong.

Solution of the present invention is on the basis of existing technology, 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 former component, upper plate, on every side sidewall, going to the bottom contains reinforce, it is characterized in that having reinforce to stretch in the alternative body in sidewall, at least a body of going to the bottom at upper plate, on every side and anchoring wherein.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, resistance to shock is strong, and the ability of particularly resisting alternation load or periodicity load action is strong; Simultaneously, cavity former component also has characteristics such as simple in structure, that intensity is high, making is easy, cost is low, the hollow building cover, roof system, body of wall, sole plate or the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention also be upper plate, on every side the reinforce in sidewall, the wherein a kind of body in going to the bottom stretch in the another kind of body and be connected with reinforce welding, colligation, riveted joint, screw in its body, hook is integral, perhaps reinforce also stretches out outside the cavity former component.Like this, reinforce stretch into above-mentioned upper plate, on every side sidewall or go to the bottom in wall body in and be connected with wherein reinforce, with upper plate, sidewall or go to the bottom connects as one on every side, has strengthened the globality of cavity former component greatly, has improved shock resistance; If reinforce also stretches out cavity former component, then more firm with the Cast-in-place concrete bonding, the globality of superstructure is better.

Feature of the present invention also be to go to the bottom have in the body at least a reinforce to stretch in the ambient side wall body and anchoring wherein.Like this, the reinforce in the body of going to the bottom stretch in the ambient side wall body and anchoring wherein, strengthened the base plate and the bonding strength of sidewall on every side greatly, make it more solid and reliable, can effectively prevent the obscission of going to the bottom, prevent to go to the bottom and the Cast-in-place concrete rib between the crackle generation.

Feature of the present invention also is on every side to have at least a reinforce to stretch in the sidewall go to the bottom in the body and anchoring wherein.Like this, reinforce in the sidewall stretches into the interior also anchoring of the body of going to the bottom wherein on every side, and sidewall and the steadiness that is connected of going to the bottom around having strengthened greatly make cavity former component have good whole more, can effectively prevent the obscission of going to the bottom, prevent to go to the bottom and the Cast-in-place concrete rib between crackle produce.

Feature of the present invention also be described reinforce from upper plate, on every side sidewall or go to the bottom at least one expose.Like this, when cavity former component was applied in the cast-in-situ concrete hollow floor, reinforce and Cast-in-place concrete that it exposes combined, and have improved the globality of hollow building cover greatly, made that cavity former component energy participation structure is stressed jointly, had improved the mechanical property of superstructure.
