Description

A kind of cast-in-situ reinforcing steel bar concrete hollow slab

(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, cast-in-situ concrete hollow floor is to use wider floor structural form, and the lightening permanent loose tool of filling in it has hollow section and cavity former component.Is that ZL99249798.1, name are called " filling reinforced concrete fiber reinforcement type thin-wall member " utility model patent as the applicant in the patent No. of application on November 29th, 1999, it discloses a kind of thin-wall mould-shell member, comprise upper plate, sidewall, lower shoe on every side, upper plate, sidewall, lower shoe surround the polyhedron cavity on every side.And for example the applicant in the application number of November 23 calendar year 2001 application be 01140106.0, publication number is that CN1356442, name are called " a kind of mould with cavity structure for casting reinforced concrete floor slab " application for a patent for invention, its disclosed shuttering member comprises " upper plate, sidewall, lower shoe on every side; upper plate, sidewall, lower shoe surround the polyhedron cavity former component, characteristics such as that this cavity former component has is in light weight, intensity is high, simple in structure, convenient construction and transport on every side.For another example the applicant in the application number of November 23 calendar year 2001 application be 01139992.9, publication number is that CN1348040, name are called " a kind of cavity member for floor slab with hidden and dense ribs " application for a patent for invention, its disclosed shuttering member comprises cavity template, structure base plate, structure base plate and cavity template are connected to form polyhedral structure, and reinforcing rib is arranged on Cavity structural member.Have characteristics such as intensity and rigidity are big, simple in structure, in light weight, convenient construction and transport.When being applied to close rib building roof, this Cavity structural member is wrapped up in and is contained in the cast-in-situ reinforced concrete, and Cavity structural member is the Cast-in-place concrete rib alternately each other.But this hollowcore slab is at the rotation angle position of Cavity structural member, stressed more complicated, and stress is more concentrated, easily produces the crack, even cracking destruction, therefore, develops 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 mechanical property good, reduce stress and concentrate, prevent the characteristics such as generation in crack.

Solution of the present invention is on the basis of existing technology, include steel bar concrete, Cavity structural member, Cavity structural member is wrapped up in and is contained in the cast-in-situ reinforced concrete, Cavity structural member is connected and composed by structure base plate and cavity template, the cavity template is provided with at least one reinforcing rib, and Cavity structural member is the Cast-in-place concrete rib each other alternately each other, it is characterized in that being provided with at least one chamfering, formed the reinforcing rib of Cast-in-place concrete at chamfer site in the corner of Cavity structural member.Like this, owing to be provided with at least one chamfering in the corner of Cavity structural member, formed the reinforcing rib of Cast-in-place concrete at chamfer site, thereby can eliminate the stress concentration phenomenon at hollowcore slab cavity component corner position effectively, prevent the generation in crack, and can bear bigger point load effect and do not destroy, improve the mechanical property of hollowcore slab, thereby reached purpose of the present invention; In addition, cast-in-situ reinforcing steel bar concrete hollow slab also has characteristics such as simple in structure, that intensity is high, construction is easy, 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 Cavity structural 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, Cavity structural 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.

Feature of the present invention is that also described Cavity structural member flushes with the end face of cast-in-situ reinforcing steel bar concrete hollow slab, and the Cast-in-place concrete lower plate is arranged under it, and lower plate links to each other with the Cast-in-place concrete rib.Like this, greatly facilitate hollowcore slab top gut line and lay, can under the situation of not damaging the floor force structure, easily various pipelines or line box be installed to floor inside and not increase slab thickness, increased the usage space of building indirectly, made its structure more reasonable.

Feature of the present invention is that also described Cavity structural member flushes with the bottom surface with the end face of cast-in-situ reinforcing steel bar concrete hollow slab respectively.Like this, the hollowcore slab form of structure that Cavity structural member flushes with the bottom surface with the end face of cast-in-situ reinforcing steel bar concrete hollow slab respectively greatly facilitates the laying of vertical pipeline in the building, has avoided having protected structure because of the cutting at the hole damage to structure; Simultaneously, also can save a large amount of templates, reduce the loss of template.

Feature of the present invention is that also the Cast-in-place concrete upper plate is arranged on the described Cavity structural member, and upper plate links to each other with the Cast-in-place concrete rib, and the Cast-in-place concrete lower plate is arranged under the Cavity structural member, and lower plate links to each other with the Cast-in-place concrete rib.Like this, be provided with Cast-in-place concrete, improved the integrality performance of the structure of hollowcore slab greatly in the Cavity structural member up and down, and the mechanical property of hollowcore slab.

Feature of the present invention is that also the horizontal corner of described Cavity structural member is provided with horizontal chamfering, and Cast-in-place concrete has formed the reinforcing rib of Cast-in-place concrete in horizontal chamfering.Like this, the Cast-in-place concrete reinforcing rib has been strengthened the strength and stiffness at hollowcore slab cavity component corner position greatly, has improved the supporting capacity of hollowcore slab, makes its structural price ratio more reasonable.

Feature of the present invention is that also the vertical corner place of described Cavity structural member is provided with vertical chamfering, and Cast-in-place concrete has formed the reinforcing rib of Cast-in-place concrete in vertical chamfering.Like this, vertical Cast-in-place concrete reinforcing rib has been strengthened the crossed node of Cast-in-place concrete rib, makes that position of joints is not easy-to-draw breaks badly, has promoted tension, resistance to compression and the shear resistance of hollowcore slab structure significantly.

Feature of the present invention also is to be provided with in the described Cavity structural member at least one rod member, and perhaps rod member also is connected with at least one reinforcing rib.Like this, when the rod member bearing load, rod member can be delivered to load stress with it on the reinforcing rib that intersects, and is delivered to via reinforcing rib on the cast-in-situ concrete structure such as Structure Beam-column again.
