(1) technical field
The present invention relates to a kind of molding hollow component in use for filling in concrete in site.
(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 like 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 processed 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 processes 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.For another 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, its disclosed mould with cavity structure, 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 structural member, characteristics such as that this Cavity structural member has is in light weight, intensity is high, simple in structure, convenient construction and transport simultaneously; when reality is used; going to the bottom, it is stressed to participate in, and can be hung the greater weight object and in-situ deposited prefabricated bonding surface does not ftracture, in addition; this kind polyhedron Cavity structural member; in order to prevent effectively and to disperse the stress between formwork and the Cast-in-place concrete to concentrate, the elimination straight slit, make go to the bottom and Cast-in-place concrete between bond better; Improve overall performance, its peripheral side of going to the bottom can be made interior puncture dihedral, back taper, waveform, serrated-surface.Above-mentioned disclosed these Cavity structural members 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 structural member, 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, therefore, develop a kind of novel molding hollow component in use for filling in concrete in site for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of molding hollow component in use for filling in concrete in site, have the mechanical property of improving superstructure, the sectional dimension that reduces the Cast-in-place concrete rib, minimizing reinforcing bar and concrete consumption, reduce characteristics such as superstructure cost, easy construction.
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 structural member; It is characterized in that described sidewall) and go to the bottom between be provided with at least one end costal fovea groove, sidewall is provided with at least one vertical groove around at least one of Cavity structural member, is provided with at least one in stiffening rib, bracing boom, the reinforcing rib in the enclosed cavity of Cavity structural member.Like this, owing to be provided with groove at sidewall and between going to the bottom, after Cavity structural member is applied to cast-in-situ concrete hollow floor; Close rib building roof particularly, the Cast-in-place concrete rib between its Cavity structural member has formed the inverted T-shaped rib, and its shape of cross section has become inverted T-shaped by rectangle; Thereby the mechanical property of superstructure improves greatly, can reduce the sectional dimension of Cast-in-place concrete rib, reduces reinforcing bar and concrete consumption; Reduce the superstructure cost, simultaneously, because the sidewall on every side of Cavity structural member is provided with at least one vertical groove; Concrete can form the reinforcing rib of Cast-in-place concrete pier, post or Cast-in-place concrete rib between the Cavity structural member in groove, particularly when Cavity structural member is close to arrangement in superstructure, in vertical groove, then forming vertical pier or post; In end costal fovea groove, then formed the Cast-in-place concrete rib; The consumption of reinforcing bar and concrete further reduces, and superstructure is corresponding to have formed shearing pier formula hollow building cover, thereby the mechanical property of superstructure further improves; In addition; Characteristics such as that Cavity structural member 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 the object of the 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.
Characteristic of the present invention also be to have on the sidewall around at least one of described Cavity structural member at least one run through upper surface and end costal fovea groove vertical groove.Like this; When Cavity structural member was applied in the Cast-in-place Concrete Building Floor, Cast-in-place concrete poured in the vertical groove that runs through upper surface and end costal fovea groove, on the cast-in-place hidden rib, has formed the vertical reinforcement of Cast-in-place concrete; Improve the strength and stiffness of Cast-in-place concrete rib, improved the combination property of Cast-in-place Concrete Building Floor greatly.
Characteristic of the present invention also be described Cavity structural member around have on the sidewall at least one run through upper and lower surfaces vertical groove.Like this, when Cavity structural member was applied in the Cast-in-place Concrete Building Floor, Cast-in-place concrete poured in the vertical groove, on the cast-in-place hidden rib, had formed the vertical reinforcement of Cast-in-place concrete, had improved the strength and stiffness of Cast-in-place concrete rib, had improved the combination property of Cast-in-place Concrete Building Floor greatly.
