Abstract
The invention discloses a rectangular concrete filled beam with a hollow steel tube. Concrete is poured between a rectangular outer steel tube and an inner sleeve which are coaxial, and the inner sleeve is hollow. The rectangular concrete filled beam with the hollow steel tube has the advantages that: (1) due to the 'look around' effect of the rectangular outer steel tube and the inner sleeve, the compressive strength of the concrete of the beam is obviously improved; (2) the section of the beam is small, the deadweight of the beam is light, and the indoor useful space is large; and (3) cables can be laid in the inner sleeve.
Description
Technical field
The application relates to building structure.
Background technology:
At present, reinforced concrete beam is often adopted in building structure, is characterized in easy construction, and is cheap, but from great, cross dimension is big, reduced the indoor usefull space; Though the prestressed steel reinforced concrete beam section is little, from heavy and light, construction is complicated, and use is restricted.Concrete filled steel tube is as a kind of new structure, the intensity height, and section is little, but is mainly used in compressed member such as pillar etc., does not make beam as yet and uses.How to reduce the cross dimension of beam, reduce the deadweight of beam, just need a kind of new structure beam of design.
Summary of the invention
The present invention seeks to reduce the cross dimensions of beam, alleviate the deadweight of beam, improve the tensile strength of beam.Mentality of designing is that the section with encased structures makes rectangle, and intermediate hollow is made the concrete-filled steel tubular hollow beam, is named as rectangular concrete filled beam with hollow steel tube.The specific design scheme is:
Rectangular concrete filled beam with hollow steel tube is made up of the outer steel pipe of rectangle, concrete and inner sleeve, and manufacturing process is as follows:
1, the outer steel pipe of rectangle is lain in a horizontal plane on the solid smooth ground, offer several at its end face and build mouth, be used for concreting;
2, inner sleeve is inserted in the outer steel pipe of rectangle and remain coaxial, hoisted in position then;
3, build and exempt from vibration concrete from building mouth, up to water full till;
4, concrete is carried out maintenance, till reaching prescribed strength;
5, mouth is built in sealing, adopts the steel plate welded closure.
Inner sleeve can be tubing such as steel pipe, steel-plastics composite pipe, PVC-U pipe.
The application's good effect is:
(1) owing to the effect of looking about of outer steel pipe of rectangle and inner sleeve, the concrete compressive strength of beam obviously improves;
(2) section of beam is little, and from heavy and light, the indoor usefull space is big;
(3) inner sleeve can be used for laying cable.
Description of drawings
Fig. 1 is the rectangular concrete filled beam with hollow steel tube schematic diagram, among the figure: 1---and the outer steel pipe of rectangle; 2---exempt from vibration concrete; 3---inner sleeve.
The specific embodiment
As shown in Figure 1, on smooth solid ground, with outer steel pipe 1 horizontal positioned of rectangle, and offer several at its end face and build mouth, then inner sleeve 3 is inserted in the outer steel pipe 1 of rectangle and remains coaxial, after the hoisted in position, build and exempt from vibration concrete 2 from building mouth, water full maintenance, when concrete strength reaches prescribed strength, can adopt welding method, mouth is built in sealing, rectangular concrete filled beam with hollow steel tube.
Claims (1)
1, rectangular concrete filled beam with hollow steel tube is characterized in that between the steel pipe and inner sleeve, watering full concrete outside coaxial rectangle.
