Description

A kind of concrete hollow board

(1) technical field

The present invention relates to a kind of concrete hollow board.

(2) background technology

At present, the cast-in-situ reinforced concrete hollow concrete hollow board is to use wider concrete hollow board form of structure, has that speed of application 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 steel bar concrete hollow board.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 cast-in-situ reinforced concrete hollow concrete hollow board, can satisfy the needs of latticed, the cellular concrete of finding time, form close rib hollow steel bar concrete hollow board.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, inconsistent phenomenon easily takes place in mutually positioning inconvenience, influences the construction quality of hollow steel bar concrete hollow board, simultaneously also influence efficiency of construction, 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 mechanical property 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, the cross sectional shape of internal-rib die cavity is an inverted T-shaped.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 cast-in-situ reinforcing steel bar concrete hollow slab 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 the cross sectional shape of internal-rib die cavity is an inverted T-shaped, Cast-in-place concrete has formed the Cast-in-place concrete rib of inverted T-shaped in the internal-rib die cavity, thereby the intensity of hollowcore slab and rigidity are bigger, therefore, concrete hollow board has easy construction, the efficient height, characteristics such as construction quality and mechanical property are good, thereby reached purpose of the present invention, be applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete hollow slab, concrete hollow board, roof system, sole plate, body of wall, hollow bridges is used, and is specially adapted to hollow no beam steel concrete hollow board and uses.
