Abstract
The invention belongs to the field of engineering structures, and in particular relates to a novel multi-grid stiffening hybrid structure. The structure is formed by combining an inner steel pipe, an outer steel pipe, stiffening plates and a filling material, wherein the outer steel pipe is octagonal; the inner steel pipe is round or octagonal; the stiffening plates are arranged between the outer steel pipe and the inner steel pipe and divide a space between the outer steel pipe and the inner steel pipe into a plurality of grids; the filling material is filled among the grids; the filling material can be filled in the inner steel pipe or the inner steel pipe can be hollow; the inner steel pipe and the outer steel pipe are welded steel pipes, seamless steel pipes, cold-bent steel pipes or other steel pipes for the structure; the stiffening plates are steel plates for the structure; and building materials such as concrete, cement mortar or an adhesive and the like are taken as the filling material. The multi-grid stiffening hybrid structure solves the problem that a huge column is connected with beams in a plurality of directions in space simultaneously; in addition, the concrete in the grids is strongly constrained, so the bearing capacity and anti-seismic capacity of the structure are greatly improved; moreover, the structure has high fire resistance.
Description
Technical field
The invention belongs to the engineering structures field, particularly a kind of novel multi-region lattice hybrid structure of putting more energy into.
Background technology
In super highrise building, large public building, long span bridge beam and structure of the subway, encased structures often needs to be connected with the beam of a plurality of directions during as huge post.If adopt traditional steel core concrete column, the beam-column connection of multi-direction connection will cause node area stress raisers phenomenon and make node can not transmit load effectively, and the problem of shear resistance deficiency is arranged, and has brought huge hidden danger to building safety.
Summary of the invention
The invention provides a kind of novel multi-region lattice hybrid structure of putting more energy into, its objective is the problem that the huge post of solution in super highrise building, large public building, long span bridge beam and structure of the subway is connected with the beam of a plurality of directions in space.
The technical solution used in the present invention is:
These multi-region lattice hybrid structure of putting more energy into is combined by inner layer steel pipe, outer layer pipe, stiffener and packing material.It is octagonal structure that outer layer pipe adopts cross section, and it is circular or octagonal structure that inner layer steel pipe adopts cross section; Equally distributed eight stiffeners are set between inner layer steel pipe and the outer layer pipe, and are a plurality of districts lattice, between each district's lattice, insert packing material the spatial division between inner layer steel pipe and the outer layer pipe.
Insert packing material in the described inner layer steel pipe or adopt hollow form.
The structural steel pipe that described inner layer steel pipe and outer layer pipe adopt welded steel pipe, seamless steel pipe, cold-bent pipe or other modes to form.
Described stiffener adopts structural steel plate.
Described packing material uses the constructional materials that comprises concrete, cement mortar, adhesive.
Beneficial effect of the present invention is:
(1) outside inner layer steel pipe, be provided with the stiffener of steel pipe outside the octagon and a plurality of directions, like this beam just can a plurality of directions directly with outside steel pipe be connected, and load is passed to interior steel pipe and concrete effectively by stiffener.
(2) concrete parcel has suppressed the cripling of stiffener and interior steel pipe node area effectively, has guaranteed that internal force is at the effective transmission of node area and the bearing capacity of node area.
(3) because stiffener is a plurality of districts lattice with the spatial division between inner layer steel pipe and the outer layer pipe, improved concrete degree of restraint, made structure have higher bearing capacity and anti-seismic performance.
(4) compare with the common steel tube concrete column, because interior steel pipe and stiffener be among the concrete protection, so this class formation has fire resistance preferably.
(5) the present invention is applicable to and is connected with the beam of a plurality of directions in the hinge rod structure of huge post, bridge and underground construction in all kinds of superelevation layers or the palace.
