Description
(1) technical field
The present invention relates to a kind of cast in place reinforced bar lightweight concrete board.
(2) background technology
At present, cast-in-situ concrete hollow floor has from heavy and light, economical with materials, plurality of advantages such as the shock stability that shakes is good, globality is strong, has obtained extensive use in building trade.It is permanent core that cast-in-situ concrete hollow floor becomes pole, as paper tube, plastic pipe, metal bellows, core light material etc., these tubular core molds or member mainly consider to find time concrete, reduce superstructure weight.It as the patent No. 99249755.8 cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder, it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, have advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.But this hollow section is in being applied to cast-in-situ concrete hollow floor the time, and unavoidable tube wall surface occurs breaking or hole in carrying, the work progress, and concrete is easy to fill up the inner chamber of hollow thin-wall pipe like this, thereby loses the meaning of employing hollow thin-wall pipe.For this reason, Kweiyang mark is thrifty waits people's invention and has applied for that the patent No. is that ZL01206422.X, name are called " open-spandrel sandwich board built-in template " utility model patent.This built-in template is solid, and this template is the solid built-in template of expansion type polystyrene plastics, or is the solid built-in template of magnesium oxychloride material, or is the solid built-in template of perlite material; The cross sectional shape of the built-in template that this is solid can be square, rectangle, circle, ellipse, arc or with the solid section shape of circular arc and rectilinear(-al).Owing to adopted technique scheme, in work progress, even on solid built-in template, crackle or hole occur, concrete also can only fill up this crackle or hole and not influence the inner chamber of open-spandrel sandwich board, and can continue normal use, improve the yield rate of built-in template greatly, reduced cost of manufacture.This solid built-in template, when the built-in template applications that is made into tubulose during in the cast in place reinforced bar lightweight concrete board, because the tubulose concrete in the solid light pipe centre in the cast in place reinforced bar lightweight concrete board is found time, along pipe the Cast-in-place concrete rib arranged vertically, and laterally found time by solid light pipe owing to steel bar concrete, can't bear the effect of complicated pulling force, pressure, shearing, moment of torsion etc., the bigger situation of cast in place reinforced bar lightweight concrete board two direction rigidity great disparities has appearred, and become the cast-in-situ reinforced concrete one-way slabs, can't form well word rib equivalent transverse and longitudinal.Therefore, develop a kind of novel cast in place reinforced bar lightweight concrete board 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 reinforced bar lightweight concrete board, have characteristics such as mechanical property is good, two-way stiffness difference is little, easy construction.
Solution of the present invention is on the basis of existing technology, include steel bar concrete, light pipe, light pipe is a solid light pipe, light pipe is wrapped up in and is contained in the cast-in-situ reinforced concrete, be vertically arranged with the cast-in-situ reinforced concrete longitudinal rib between the light pipe, it is characterized in that light pipe is provided with at least one groove, cast-in-situ reinforced concrete has formed the cast-in-situ reinforced concrete cross rib in groove, and links to each other with the cast-in-situ reinforced concrete longitudinal rib.Like this, because body is provided with groove, Cast-in-place concrete can form cross rib in groove, thereby, cast in place reinforced bar lightweight concrete board vertical cross stiffness difference significantly reduces, can form two-way slab, improve the mechanical property of cast in place reinforced bar lightweight concrete board greatly, simultaneously, easy construction, thereby reached purpose of the present invention, be applicable to that thistle board, roof system, sole plate, body of wall or the bridge of various cast-in-situ reinforced concretes or prestressed reinforced concrete uses, be specially adapted to arch without beam and use.
Feature of the present invention also is to be provided with rib between the cast-in-situ reinforced concrete end between the pipe end of described light pipe, and links to each other with the cast-in-situ reinforced concrete longitudinal rib.Like this, the vertical cross stiffness difference of cast in place reinforced bar lightweight concrete board still less, mechanical property is better.
Rib has formed rib between the elongated end of Cast-in-place concrete between the end that feature of the present invention also is to be provided with between the described multiple row light pipe pipe end.Like this, not only the vertical cross stiffness difference of cast in place reinforced bar lightweight concrete board further reduces, and mechanical property improves greatly, and it is easier to construct, and speed of application is faster.
