Description
The application for the applying date be that February 26, application number in 2003 are 03118106.6, name is called the dividing an application of application for a patent for invention of " a kind of steel bar reinforced hollow concrete roof cast-in-situs ".
(1) technical field
The present invention relates to a kind of steel bar reinforced hollow concrete roof cast-in-situs.
(2) background technology
At present, cast-in-place concrete cored since have quick construction, template loss little, can realize large bay, cut off flexibly, advantage such as deadweight is little, more and more widely used.The patent No. as applicant's application is that ZL99232922.1, name are called " thin-wall hollow roof in-situ deposited with concrete ", it is made up of steel bar concrete and thin wall cylinder noggin piece; the thin wall cylinder noggin piece is embedded in the steel bar concrete; 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.Light-wall pipe in this steel bar reinforced hollow concrete roof cast-in-situs, the effect that often will bear complicated pulling force, pressure, moment of torsion easily produces phenomenons such as cracking, destruction, influences the use of superstructure, therefore, develops a kind of novel steel bar reinforced hollow concrete roof cast-in-situs for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of steel bar reinforced hollow concrete roof cast-in-situs, characteristics such as its superstructure has light-wall pipe intensity height, is difficult for cracking destruction, simple in structure and long service life.
Solution of the present invention is on the basis of existing technology, comprises steel bar concrete, light-wall pipe, and light-wall pipe is embedded in the steel bar concrete, it is characterized in that being filled with in the light-wall pipe light material.Like this, owing to accompany at least one thin band in the tube wall of the light-wall pipe in the superstructure, its tension, resistance to compression, antitorque performance improve greatly, thereby have the intensity height, be difficult for characteristics such as cracking destruction, the long service life of corresponding superstructure, structure is also simple simultaneously, cost is low, has reached purpose of the present invention preferably.Light material can be foamed plastics, expanded perlite, expanded vermiculite, foaming or aerated light concrete, rock wool, mineral wool, glass wool, haydite or haydite concrete, like this, the insulation of superstructure, heat insulation, sound insulation value is better.
Feature of the present invention is that also the light material of filling is a tubulose.
Feature of the present invention also be the light material of filling around be combined into integral body with light-wall pipe.
Feature of the present invention is that also the termination of the light material of filling and plug or stiffening rib are combined into integral body.
Feature of the present invention is that also the light material of filling is a foamed plastics.
Feature of the present invention is that also the light material of filling is an expanded perlite.
Feature of the present invention is that also the light material of filling is an expanded vermiculite.
Feature of the present invention is that also the light material of filling is foaming or aerated light concrete.
Feature of the present invention is that also the light material of filling is a rock wool.
Feature of the present invention is that also the light material of filling is a mineral wool.
Feature of the present invention is that also the light material of filling is a glass wool.
Feature of the present invention is that also the light material of filling is haydite or haydite concrete.
Feature of the present invention also is to accompany thin band in the tube wall of light-wall pipe.Like this, because accompany at least one thin band in the tube wall of the light-wall pipe in the superstructure, its tension, resistance to compression, antitorque performance improve greatly, thereby have the intensity height, be difficult for characteristics such as cracking destruction, the long service life of corresponding superstructure, structure is also simple simultaneously, cost is low.
Feature of the present invention also be thin band in the tube wall of light-wall pipe in tube wall along tube axis direction or intersected with each other or parallel or form with netted or their combination setting along pipe Zhou Fangxiang, be provided with one or more layers.Like this, the thin band in the tube wall of the light-wall pipe in the superstructure can be provided with flexibly according to needs actual and design, and impact strength is higher, has made things convenient for design, has produced and construction, helps reducing the construction cost of superstructure.
Feature of the present invention is that also there are plug or stiffening rib in the two ends of light-wall pipe, and perhaps an end is a stiffening rib for the plug other end.Like this, because the light-wall pipe two ends have plugging part, during floor construction, the light-wall pipe pipe end does not need on-the-spot shutoff, and Cast-in-place concrete can not enter in the tube wall cavity, thereby it is more convenient to construct; If plug stiffening rib simultaneously, the defective that the cassette ceiling hollow part does not have lateral stressed member has been eliminated in then force-applied on a degree, power transmission.
Feature of the present invention also is to be provided with at least one in stiffening rib or bracing boom or the reinforcing rib in light-wall pipe.Like this, the intensity and the rigidity of superstructure are higher, in the stressed and power transmission of horizontal energy along pipe, have further improved the stress performance of superstructure, the application life of having improved superstructure.
Feature of the present invention also is to accompany in plug or stiffening rib or bracing boom or reinforcing rib at least one at least one thin band.Like this, the mechanical property of superstructure further improves, longer service life.
Feature of the present invention is that also thin band is to have hole, seam, groove, sour jujube head, concavo-convex, concavo-convex porose, impression, hair sour jujube, the fiber that exposes shortage, exasperate or their compound metal tapes or be braid over braid, strap, sandwich tape.Like this, thin band is wide in variety, and the production of light-wall pipe is more convenient, cost is lower, and the construction cost of corresponding superstructure is lower.
Feature of the present invention is that also the tube wall of light-wall pipe is the tube wall of layer structure, by the glued bed of material of one deck, one deck fleece or cloth or wire lath, the glued bed of material of one deck again, one deck fleece or cloth or wire lath again, the glued bed of material of one deck again, overlapping gluing like this forms, and fleece or cloth or wire lath are at least more than one deck.Like this, the tube wall of light-wall pipe is that layer structure and thin band are compound, and the intensity of corresponding superstructure is higher, and globality is better, and impact resistance is stronger.
Feature of the present invention is that also light-wall pipe is combined by little segmented assembly.Like this, at some privileged sites, the construction of superstructure is easier, convenient, can satisfy the needs of different occasions.
Feature of the present invention also is to have between the little segmentation at least one binding in thin band or steel wire or the gauze wire cloth.Like this, the bonding between the segmentation tube wall better, more firm, globality is better.
Feature of the present invention is that also light-wall pipe is provided with the pipe of drawing-in wire or at least one in the air chimney.Like this, during floor construction, the construction and the laying of convenient various pipelines.
That feature of the present invention also is is fluted on the light-wall pipe, pothole, convex tendon, projection, dew muscle, reveal net, reveal stiffening rib, reveal bracing boom or reveal in the thin band at least one.Like this, the build-in between light-wall pipe and the Cast-in-place concrete is better, and the intensity and the globality of superstructure are higher.
Feature of the present invention is that also light-wall pipe is provided with align member.Like this, during floor construction, can make things convenient for the installation of light-wall pipe, accelerate speed of application, help reducing construction cost.
