Abstract
The present invention relates to a cast-in-situ reinforced concrete hollow slab, including reinforced concrete and form members which are wrapped and contained in the reinforced concrete. The form members are alternately arranged, between them the cast-in-situ concrete rib is formed respectively. It is characterized by that on at least one peripheral side wall of said form member a connecting component is set, at least two form members are connected into one body by means of the connecting component and preplaced in the cast-in-situ reinforced concrete hollow slab. Said invention is applicable to various cast-in-situ concrete floor, roof, wall body, foundation bedplate and structure of road and bridge engineering, specially applicable to hollow beamless floor.
Description
(1) technical field
The present invention relates to a kind of cast-in-situ reinforcing steel bar concrete hollow slab.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ hollow floor plate becomes pole, as paper tube, plastic pipe, horniness thin-walled tube, metal bellows, core light material, shuttering member etc.These permanent cores mainly consider to find time concrete, alleviate floor weight.As the patent No. by applicant application be 99249798.1, the applying date be November 29 in 1999 day, be called " filling reinforced concrete fiber reinforcement type thin-wall member " utility model patent, it is made up of with sealing box body, form cavity thin-walled box carcass, the shape of carcass can be circle, square, spherical, polygon or other abnormity, has intensity height, resistance to deformation, good, easy to manufacture, the low cost and other advantages of anti-vibration performance.This shuttering member, when being applied to cast-in-situ reinforcing steel bar concrete hollow slab, shuttering member is the Cast-in-place concrete rib alternately each other.But when this cast-in-situ reinforcing steel bar concrete hollow slab is constructed; easily produce displacement or dislocation between the shuttering member each other; lay inconvenient; the Cast-in-place concrete rib width that is prone between the shuttering member is inconsistent; the inconsistent phenomenon of protective layer thickness, thus the total quality and the stress performance of cast-in-situ reinforcing steel bar concrete hollow slab influenced, increase difficulty of construction; therefore, develop a kind of novel cast-in-situ reinforcing steel bar concrete hollow slab for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-situ reinforcing steel bar concrete hollow slab, have characteristics such as construction quality is good, construction is easy.
Solution of the present invention is on the basis of existing technology, include steel bar concrete, shuttering member, shuttering member is wrapped up in and is contained in the cast-in-situ reinforced concrete, shuttering member alternately, be the Cast-in-place concrete rib each other, sidewall is provided with link around it is characterized in that at least one of shuttering member, and at least two shuttering members connect as one by link and are preset in the cast-in-situ reinforcing steel bar concrete hollow slab.Like this, because sidewall is provided with link around at least one of shuttering member, at least two shuttering members connect as one by link and are preset in the cast-in-situ reinforcing steel bar concrete hollow slab, thereby the construction quality of hollowcore slab is good, shuttering member is laid easy to connect, can not produce displacement or dislocation each other, and construction easily, phenomenons such as Cast-in-place concrete rib width between the shuttering member is inconsistent, protective layer thickness is inconsistent can not occur, thereby reach purpose of the present invention; Simultaneously, cast-in-situ reinforcing steel bar concrete hollow slab also has characteristics such as simple in structure, that intensity is high, rigidity is big, cost is low, is applicable to the structure of various Cast-in-place Concrete Building Floor, roof system, body of wall, sole plate and road and bridge engineering, is specially adapted to hollow arch without beam.
Feature of the present invention is that also described shuttering member flushes with the bottom surface of cast-in-situ reinforcing steel bar concrete hollow slab, and the Cast-in-place concrete upper plate is arranged on it, and upper plate links to each other with the Cast-in-place concrete rib.Like this, when building cast-in-situ reinforcing steel bar concrete hollow slab, shuttering member flushes with the bottom surface of cast-in-situ reinforcing steel bar concrete hollow slab, can save a large amount of templates, reduces the loss of template, simultaneously, has also reduced the consumption of Cast-in-place concrete, has saved material, has reduced the cost of floor.
