A kind of cast-in-place concrete cored
The application for the applying date be that May 6, application number in 2003 are 200510135868.3, name is called the dividing an application of application for a patent for invention of " a kind of cast-in-place concrete cored ".
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(2) background technology
Arch without beam is that present Cast-in-place Concrete Building Floor is used wider floor structural form, have 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 lightweight member 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, and it is made up of horniness thin-walled tube and two plugs, is applied to use as lightweight member in the arch without beam.The beam army in Shijiazhuang City, Hebei Province city and for example, the patent No. in application on February 23rd, 2000 is that ZL00203695.9, name are called the formwork that uses in " combination concrete hidden rib floor structure " utility model patent, Instructions Page 2 the 5th walk to the 7th line description " formwork can be solid; also can be hollow; light materials such as available plant straw, glass fiber reinforced plastic, sheet iron plate, glass fibre cement are made; its profile can be made shapes such as rectangle, circle, polygon according to designing requirement; ", being applied to equally make up in the concrete hidden rib superstructure also is to use as lightweight member.But no matter be hollow section or box, be applied to superstructure as permanent lightweight member after, formed superstructure comprises steel bar concrete, lightweight member, lightweight member is wrapped up in and is contained in the steel bar concrete, the stressed Force transmission parts of no superstructure in its member particularly when the lightweight member size is big, shows more obvious, simultaneously, the intensity of corresponding cast in site floor is relative with rigidity relatively poor, therefore, develops a kind of novel cast-in-place concrete cored, improve the mechanical property of hollowcore 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-place concrete coredly, its shearing resistance, torsional property improve greatly, and intensity and rigidity also are greatly improved, and simultaneously, also have characteristics such as simple in structure, easy construction, cost be low.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, lightweight member, lightweight member is wrapped up in and is contained in the steel bar concrete, it is characterized in that the cast hole that has at least one to run through in the lightweight member, in concrete or the steel bar concrete filling hole, constitute superposed column or pier, simultaneously, at least one groove that is communicated with the cast hole is arranged on external surface of structural member, constitute concrete ribs or muscle in concrete or the steel bar concrete filling groove, at least one lightweight member turning is an arc angle.Like this, because being provided with the hole of Cast-in-place concrete cast usefulness, lightweight member runs through lightweight member, after lightweight member is applied to hollowcore slab, Cast-in-place concrete enters in the hole, after treating setting and harden, form Cast-in-place concrete post or pier, thereby in lightweight member, formed the stressed and Force transmission parts of hollowcore slab, improve the mechanical property of hollowcore slab greatly, particularly improved the shearing resistance of hollowcore slab, antitorque mechanical property greatly; Simultaneously, because at least one groove that is communicated with the cast hole is arranged on external surface of structural member, Cast-in-place concrete enters into reinforcing rib or the stiffening rib that has formed the cast-in-place hollow slab plate in the groove, thereby the intensity of hollowcore slab and rigidity are greatly improved, thereby reached purpose of the present invention, also have characteristics such as simple in structure, easy construction, cost be low simultaneously, be applicable to various cast-in-situ reinforced concretes or prestressed hollow reinforced concrete roof, roof system, sole plate, body of wall, hollow bridges use, be specially adapted to hollow arch without beam and use.
