The present invention is suitable for use in in-situ cast or pre-stressed reinforced concrete floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.
Description
The application for the applying date be that June 2, application number in 2003 are 03137264.3, name is called the dividing an application of application for a patent for invention of " a kind of cast-in-situ reinforcing steel bar concrete hollow slab ".
(1) technical field
The present invention relates to a kind of used for cast-in-situ reinforced concrete hollow board hollow section.
(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 used for cast-in-situ reinforced concrete hollow board hollow section for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of used for cast-in-situ reinforced concrete hollow board hollow section, 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, comprises hollow section, and the pipe end of hollow section is provided with hush panel, and it is characterized in that has the lightweight filler in the hollow section.Like this, be filled with the hollow section of lightweight filler, have very good pressure resistance energy and shock resistance, even little breakage appears in hollow section, also can directly build concrete without repairing, simultaneously, hollow building cover has good sound insulation, heat insulation, heat-insulating property; When the used for cast-in-situ reinforced concrete hollow board hollow section 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 used for cast-in-situ reinforced concrete hollow board hollow section; satisfied 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 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 the used for cast-in-situ reinforced concrete hollow board hollow section is constructed; the docking facilities that is connected the location is arranged between hollow section and the hollow section; thereby the body laying is 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 tube and tube is inconsistent, the outer concrete cover variable thickness of pipe causes can not appear; guarantee the total quality of used for cast-in-situ reinforced concrete hollow board hollow section, satisfied the requirement of hollowcore slab stress performance, reduced construction cost.
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.
