Description
(1) technical field
The present invention relates to a kind of cast-in-situ reinforcing steel bar concrete hollow slab.
(2) prior art
At present, the most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure, and this floor structure has advantages such as speed of application is fast, cost is low.But, only use the cement mortar joint filling, thereby globality is poor, is unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur owing to firmly do not link between adjacent two precast hollow slabs.For addressing the above problem, a lot of building have adopted the method for Cast-in-place Concrete Building Floor (solid, hollow), have solved problems such as antidetonation, cracking, infiltration preferably, but this class floor construction relative difficult, and cost is higher relatively.Along with Building technology and expanding economy, the quality of building to be had higher requirement, most Cast-in-place Concrete Building Floor has all adopted the cast-in-situ concrete hollow plate technique.And the one-tenth pole in the cast-in-place hollow slab is permanent core, as paper tube, plastic pipe, metal bellows, core light material, horniness thin-walled tube etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate hollow slab floor weight.It as the patent No. 99232921.3 cast-in-place reinforced concrete filling 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, and the cross section of horniness thin-walled tube and plug shape can be circle, square, trapezoidal or other is special-shaped.During application, this hollow section is embedded in the steel bar concrete, promptly forms cast-in-place concrete cored superstructure.And for example the patent No. of applicant's application is that ZL99232922.1, name are called " thin-wall hollow roof in-situ deposited with concrete ", it comprises steel bar concrete, thin wall cylinder noggin piece, reinforced-bar concrete beam or dark beam; the thin wall cylinder noggin piece is embedded in the steel bar concrete; the cast-in-situ reinforced concrete that has formed between pipe along tube axis direction between thin-wall tube member and the thin-wall tube member is indulged rib; described thin-wall tube member is made up of horniness thin-walled tube and plug, and two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends.During the cast-in-place concrete cored floor construction of this class; be easy to generate displacement or dislocation between the hollow section body each other; lay inconvenient; be prone to phenomenons such as Cast-in-place concrete rib width between the tube and tube is inconsistent, the outer concrete cover variable thickness of pipe causes; thereby influence cast-in-place concrete cored total quality and stress performance; 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 body lay convenient, do not produce displacement or dislocation, construction easily, characteristics such as total quality is good.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, hollow section, reinforced-bar concrete beam or dark beam, the pipe end of hollow section is provided with hush panel, hollow section is wrapped up in and is contained in the steel bar concrete, the cast-in-situ reinforced concrete that has formed between pipe along tube axis direction between hollow section and the hollow section is indulged rib, it is characterized in that at least one end of hollow section is provided with the docking facilities of the location that is connected to each other between the hollow section.Like this; when cast-in-situ reinforcing steel bar concrete hollow slab is constructed; the docking facilities that is connected the location is arranged between hollow section and the hollow section; thereby body is laid easy to connect; can not produce displacement or dislocation each other; construction easily; the Cast-in-place concrete rib width that can not occur between the tube and tube is inconsistent; manage phenomenons such as outer concrete cover variable thickness causes; guaranteed the total quality of cast-in-situ reinforcing steel bar concrete hollow slab; satisfy the requirement of hollowcore slab stress performance, reduced construction cost, thereby reached purpose of the present invention; be applicable to the hollow building cover of various cast-in-situ reinforced concretes or prestressed reinforced concrete; roof system; sole plate; body of wall or hollow bridges are used, and are specially adapted to hollow arch without beam and use.
Feature of the present invention is that also the docking facilities by vertical connection location is connected to each other between at least two hollow sections, is closely to connect between the pipe end.Like this, closely connect the elongated hollow section that the back forms, when cast-in-place concrete cored construction, under the effect of its whole deadweight, can prevent hollow body come-up effectively, improved cast-in-place concrete cored construction quality.
Feature of the present invention also is to connect by the docking facilities that connects the location between at least two hollow sections, is provided with spacing between the tube and tube, has formed dark rib between the Cast-in-place concrete end in the spacing behind the pour concrete.Like this.Because of being provided with spacing between the tube and tube, during Cast-in-place concrete, in the pipe end spacing, formed dark rib between cast-in-place end, cast-in-place dark rib between its end between dark rib and body combines, formed cast-in-place two-way dark rib structure, made superstructure have more reasonable structure form, stress performance is better.
Dark rib has formed elongated dark rib each other between the Cast-in-place concrete end that feature of the present invention also is to form behind the pour concrete in the described spacing on same straight line, the bright beam in elongated dark rib and the hollowcore slab or secretly beam or supporting wall are connected.Like this, the elongated dark rib that forms between pipe end and bright beam or dark beam or supporting wall are connected, and the stress that produces in the time of cassette ceiling can being carried is directly delivered to bright beam or secretly on beam or the supporting wall, its transmission force property is better.
