Description

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.And for example Shijiazhuang City, Hebei Province city beam army is that ZL00203695.9, name are called " combination concrete hidden rib floor structure " utility model patent in the patent No. of application on February 23rd, 2000, a kind of shuttering member is disclosed in its manual, it can be solid, also can be hollow, its profile can be made shapes such as rectangle, circle, polygon according to designing requirement.And for example the Yu Shaohua of Tianjin is that ZL93206310.1, name are called " shuttering member " utility model patent in the patent No. of application on March 20th, 1993, it also discloses a kind of thin-wall mould-shell member, it makes totally-enclosed empty stomach polyhedral structure with the sidewall and the upper and lower end, establish ribs in the die housing, and adopt GRC or magnesium chloride GRC or do not have the manufacturing of sand ﹠ ceramsite cement.The applicant is 01140106.0 in the application number of application on November 23 calendar year 2001 for another example, publication number is CN1356442, name is called " a kind of mould with cavity structure for casting reinforced concrete floor slab " application for a patent for invention, its disclosed mould with cavity structure, comprise " upper plate; sidewall on every side; go to the bottom; upper plate; sidewall on every side; going to the bottom surrounds the polyhedron Cavity structural member, this Cavity structural member has in light weight, the intensity height, simple in structure, characteristics such as convenient construction and transport, simultaneously, when reality is used, going to the bottom, it is stressed to participate in, and can hang the greater weight object and in-situ deposited prefabricated bonding surface does not ftracture.Above-mentioned disclosed these cavity former components are applied in the close rib building roof, be shuttering member be again prefabricated noggin piece, have simple in structure, characteristics such as intensity is high, resistance to deformation, the anti-vibration performance is good, easy to manufacture, cost is low.But after being applied to hollow building cover, formed Cast-in-place concrete rib is the Cast-in-place concrete rib of rectangle between the cavity former component, and its stress performance is not quite reasonable, often need increase the sectional dimension of Cast-in-place concrete rib, increase reinforcing bar and concrete consumption, increase the cost of superstructure, simultaneously, at the position of finding time of cavity former component, the intensity of hollow building cover is relative with rigidity relatively poor, the ability of bearing the point load effect is relatively low, 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 the mechanical property of improving superstructure, reduce the Cast-in-place concrete rib sectional dimension, reduce reinforcing bar and concrete consumption, reduce the superstructure cost, easy construction, bear characteristics such as the ability of point load effect is stronger.

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, at least one the lateral corner place that it is characterized in that the lower bottom part of cavity former component is an inner corner trim, and sidewall is provided with at least one transverse concave groove around at least one.Like this, because the lateral corner place at the lower bottom part of cavity former component is an inner corner trim, after cavity former component is applied to cast-in-situ concrete hollow floor, close rib building roof particularly, Cast-in-place concrete rib between its cavity former component has formed the inverted T-shaped rib, its shape of cross section has become inverted T-shaped by rectangle, thereby the mechanical property of superstructure is improved greatly, can reduce the sectional dimension of Cast-in-place concrete rib, reduce reinforcing bar and concrete consumption, reduce the superstructure cost, simultaneously, because sidewall is provided with at least one transverse concave groove around the cavity former component, concrete can form the reinforcing rib of the Cast-in-place concrete rib between the cavity former component in groove, thereby has improved the mechanical property of superstructure significantly, at the position of finding time, its intensity and rigidity are bigger, and the ability of bearing the point load effect is stronger; In addition, characteristics such as that cavity former component also has is simple in structure, intensity is high, resistance to deformation, the anti-vibration performance is good, easy to manufacture, cost is low, easy construction, speed of application are fast, thereby reached purpose of the present invention, the hollow building cover, roof system, body of wall, sole plate and the hollow bridges that are applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are particularly useful for hollow arch without beam and use.

Feature of the present invention is that also all lateral corner places of the bottom of cavity former component are inner corner trim, and inner corner trim is communicated with into the inner corner trim ring.Like this, after cavity former component is applied in the cast-in-situ concrete hollow floor, Cast-in-place concrete pours in the middle of the above-mentioned inner corner trim ring, has formed mutually orthogonal concrete I-shaped rib structure in hollow building cover inside, has improved the supporting capacity of hollow building cover greatly, simultaneously, because of the bottom of cavity former component is set to inner corner trim, improved the rigidity and the intensity of cavity former component bottom, be applied in the superstructure after, Cast-in-place concrete firmly bonds cavity former component, makes its difficult drop-off, damage, generation crack.

Feature of the present invention also be the upper plate of cavity former component or on every side sidewall go to the bottom or at least one of inner corner trim in be superimposed with overlapping layers.Like this, upper plate, sidewall or go to the bottom or inner corner trim is superimposed with overlapping layers have on every side reduced the production difficulty of cavity former component significantly, simultaneously, also improve the shock resistance damage capability of cavity former component greatly, reduced the proportion of goods damageds of product, improved the production efficiency of cavity former component.
