Description
(1) technical field
The present invention relates to a kind of concrete hollow board.
(2) background technology
At present, steel bar reinforced hollow concrete roof cast-in-situs is to use wider floor structural form, has that the speed of executing is fast, structure height is little, advantages such as ceiling decoration can be cut apart and need not to room area flexibly.The lightening permanent loose tool of filling in it has various hollow sections and box, and box has hollow or solid.Is that ZL99232921.3, name are called " cast-in-place reinforced concrete filling thin wall cylinder " utility model patent as the applicant in the patent No. of application on March 10th, 1999, it is made up of horniness thin-walled tube and two plugs, is applied to use as the lightening permanent loose tool in the hollow building cover.And for example the applicant in the application number of on November 29th, 1999 application be 99115666.8, name is called " fiber-reinforced thin-wall box for filling cast-in-place reinforced concrete and manufacture method thereof ", its thin-walled box is applied in the steel bar reinforced hollow concrete roof cast-in-situs, can satisfy the needs of latticed, the cellular concrete of finding time, form hollow-ribbed floor.Thin-walled is box filled in concrete, has both made filling member, again as the hollow die shell member, plays the effect of permanent mold shell.But, when this thin-walled box is constructed as hollow die shell, need single laying construction, mutually positioning inconvenience, inconsistent phenomenon easily takes place, and influences the construction quality and the efficiency of construction of hollow building cover, simultaneously, because of hollow die shell and the mutual build-in of Cast-in-place concrete, often because of the after-contraction of Cast-in-place concrete setting and harden, and the phenomenon that occurs coming to nothing, build-in each other is not firm, therefore, develop a kind of novel concrete hollow board for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete hollow board, have characteristics such as easy construction, efficient height, construction quality and overall performance are good.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, Cavity structural member, Cavity structural member is wrapped up in and is contained in the steel bar concrete, Cavity structural member alternately, be the cast-in-situ reinforced concrete rib each other, Cavity structural member comprises hollow die shell, it is characterized in that described Cavity structural member also includes a spacer draw piece, at least two hollow die shells alternately, constitute Cast-in-place concrete internal-rib die cavity each other, at least one spacer draw piece alternate one that connects to of hollow die shell with relative or adjacent surface in the internal-rib die cavity is arranged, cast-in-situ reinforced concrete has formed the cast-in-situ reinforced concrete internal-rib in the internal-rib die cavity, and link to each other with the cast-in-situ reinforced concrete rib, at least one hollow die shell is the hollow die shell that bellows wall is arranged.Like this, because Cavity structural member by at least two hollow die shells alternately, hollow die shell connects to one by a spacer draw piece, form the hollow die shell assembly, thereby when concrete hollow board is constructed, Cavity structural member is laid to become in groups by single hollow die shell and is laid, mutually positioning very convenient, the construction quality that is difficult for inconsistent phenomenon takes place and influences concrete hollow board, efficiency of construction also improves greatly simultaneously, and, because hollow die shell is the hollow die shell that bellows wall is arranged, with the contact surface increase of Cast-in-place concrete, build-in is more firm each other, be not prone to the phenomenon of coming to nothing, can prevent the generation in crack between cavity member and the Cast-in-place concrete effectively, therefore, concrete hollow board has easy construction, the efficient height, characteristics such as construction quality and overall performance are good, thereby reached purpose of the present invention, be applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete hollow slab, superstructure, roof system, sole plate, body of wall, hollow bridges is used, and is specially adapted to hollow arch without beam and uses.
Feature of the present invention is that also described all hollow die shells are the hollow die shell that bellows wall is arranged.Like this, after Cast-in-place concrete pours into, formed many Cast-in-place concrete corrugated reinforcing ribs, strengthened the rigidity and the intensity of In-situ cast concrete board in the superstructure greatly in the outside of ripple formwork; Simultaneously, can prevent the generation in crack between Cast-in-place concrete and the cavity member effectively.
Feature of the present invention is that also described bellows wall hollow die shell is wavy metal wall hollow die shell or plastic ripple wall hollow die shell or cement glass fibre wall hollow die shell.Like this, make the raw-material diversity of hollow die shell, can require rationally to select manufacturing materials for use, be convenient to reduce the cost of manufacture of cavity member, more help cavity member applying in concrete hollow board according to the use needs and the varying strength of cavity member.
Feature of the present invention is that also the crest of ripple of described bellows wall hollow die shell or trough are parallel, quadrature, oblique or its combination each other and are provided with.Like this, be in the trough that parallel, quadrature, oblique or combination be provided with when Cast-in-place concrete pours into, corresponding formation is the Cast-in-place concrete reinforcing rib that parallel, quadrature or its combination are provided with, and improved the mechanical property of superstructure greatly.
Feature of the present invention is that also waveform, wave height, the ripple of the ripple of described bellows wall hollow die shell is wide inequality.Like this, can rationally select different wave, wave height, the wide cavity member of ripple for use, to satisfy the needs of concrete hollow board different designs according to the needs of superstructure design.
Feature of the present invention also is being connected to firm connection the between described spacer draw piece and the hollow die shell.Like this, the spacer draw piece connects as one two hollow die shells between firmly linking, and handling, installs more conveniently, helps the construction of concrete hollow board.
