Abstract
The utility model relates to an eccentric formula cavity intermediate layer steel pipe concrete beam of placing of inner tube belongs to the engineering field. The steel pipe concrete beam comprises an outer steel pipe 1, an inner steel pipe 2 and concrete 3, wherein the inner steel pipe is eccentrically arranged in a tensile area of the beam. This template is knitted to steel core concrete roof beam and process of vibrating is more simple and convenient than conventional reinforced concrete roof beam, through interior steel pipe replacement ordinary reinforced concrete roof beam's the tensile district reinforcing bar, interior cavity region need not to pour concrete, and the cable passageway can be regarded as to the inner tube region simultaneously to can regard as the prefabricated component of an assembly type structure, have advantages such as faster construction speed, dead weight are light, the installation is convenient.
Description
Technical Field
The invention relates to a hollow interlayer steel pipe concrete beam with an eccentrically placed inner pipe, belonging to the technical field of engineering.
Background
A beam is one of the most important elements in a building frame. The beams carry the entire weight of the elements of the superstructure and the roof, the most important part of the superstructure. Most beams are reinforced concrete beams, using a structure made of steel and concrete. The reinforcing steel bar bears the tensile force, and the concrete bears the pressure. But because of the reasons of materials, production and installation, the method takes labor and templates, has long period, complicated working procedures and inconvenient use.
The fabricated building has high construction speed and low production cost, and is rapidly popularized and developed all over the world. A large number of building parts are produced and processed by workshops, and the types of components mainly comprise: external wall panel, interior wallboard, superimposed sheet, balcony, air conditioner board, stair, precast beam, precast column etc..
Disclosure of Invention
The invention aims to solve the problems of complicated construction process, low speed, troublesome pipeline laying and the like of the conventional reinforced concrete beam, the inner steel pipe is used for replacing a steel bar in a tension area, a hollow area in the tension area has no concrete, the self weight is light, the installation is convenient, the hollow area of the inner steel pipe can be used as a cable channel, and the beam can be used as a prefabricated component of an assembly type building and has the advantages of labor and time saving.
The technical scheme of the invention is as follows: an inner pipe eccentric placement type hollow interlayer steel pipe concrete beam comprises an outer steel pipe, an inner steel pipe and concrete. The inner steel pipe is eccentrically arranged on the tensioned side, a hollow interlayer is formed between the outer steel pipe and the inner steel pipe, and concrete is poured into the hollow interlayer and is vibrated to be compact.
The cross section of the outer steel pipe is square.
The section of the inner steel pipe is round or square.
And filling the hollow interlayer with the concrete and vibrating the concrete to be compact.
The beam and the steel column are connected in a welding or bolt mode.
Drawings
Fig. 1 is a schematic cross-sectional view of a steel pipe concrete beam according to the present invention.
FIG. 2 is a schematic view showing the arrangement of the inner steel pipe and the outer steel pipe.
In the figure, 1 is an outer steel pipe, 2 is an inner steel pipe, and 3 is concrete.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Processing the outer steel pipe and the inner steel pipe according to the designed size as shown in figure 1 and figure 2; fixing the outer steel pipe and the inner steel pipe to form a hollow interlayer as shown in figure 2; pouring concrete into the hollow interlayer and vibrating to compact the concrete; when the concrete curing reaches the design strength value, the hollow sandwich steel pipe concrete beam with the eccentrically placed inner pipe can be formed.
Claims (1)
1. The utility model provides an inner tube eccentric placement type cavity intermediate layer steel pipe concrete beam, its characterized in that, includes outer steel pipe, interior steel pipe, concrete, outer steel pipe cross-section is square, and interior steel pipe cross-section is square or circular, the concrete is annotated full of the cavity intermediate layer and is vibrated closely knit, interior steel pipe is at the one side eccentric arrangement that is drawn and is replaced the district reinforcing bar that is drawn, and interior steel pipe region is as the cable passageway, inner tube eccentric placement type cavity intermediate layer steel pipe concrete beam can make and become assembled building element, interior outer steel pipe and steel column connected mode are welding or bolted connection.
