Abstract
One kind splicing multi-chamber cross tube concrete column, is made up of rectangular steel pipe (1), U-shaped steel (2), concrete (3) and weld seam (4)；Two U-shaped steel are welded relatively outward in the rectangular steel pipe long side direction, form three chambers, and the casting concrete in each chamber.The present invention not only possesses the advantages of high, simple in construction general bearing capacity of concrete-filled steel tube, easy construction, and can slow down or prevent that larger flexing occurs in the middle part of rectangle steel tube wall under pressure.Meanwhile, flexibly, layout is easy, can be preferably connected with wall for design size of the present invention, and then can avoid producing rough phenomenon, the effective utilization rate for improving the interior space with indoor wall junction metope.
Description
Technical field
The present invention relates to a kind of multi-chamber cross tube concrete profiled pile component, building engineering structure is mainly used in
Technical field, is particularly applied in the engineering using concrete filled steel tubular member.
Background technology
With state fundamental construction advance with building structure science and technology progress, construction industry by crosswisely develop by
Gradually switch to longitudinal development, that is, reduce the floor space of building, living space is found to high-altitude even superaltitude, skyscraper,
Longspan structure has become one of Main way of building structure development.So as to the appearance of assessment of steel-concrete hybrid structure
It is the inevitable outcome that modern project scientific and technological progress and construction technology develop to industrialized production.Wherein concrete filled steel tube conduct
One kind of steel-concrete combined structure, with high capacity, anti-seismic performance is good, concrete ductility is good, fire resistance is good, construction
The easy and cost economic series of advantages such as rationally.As a kind of emerging combining structure form, concrete filled steel tube
Apply has extensive development in China, can be advantageously applied to some load-carrying members (such as high-level structure lower post, industrial premises
Post etc.), tall and slender structure (such as high-rise and high-rise building) and large-span structure (such as bridge structure).
Concrete filled steel tube is different by section form, is divided into Concrete-Filled Square Steel Tube, concrete filled steel tube and polygonal steel pipe mixed
Solidifying soil, and at present with more generally side, concrete filled steel tube.But in actual house desigh, Concrete-Filled Square Steel Tube
Post often occurs revealing post phenomenon, and concrete-filled circular steel tube column is poorly fully connected with wall sometimes, therefore special-shaped steel pipe concrete
Developed.Wherein, cross tube concrete column can apply to the center pillar in house well, can preferably connect with wall
Connect, it is to avoid uneven at wall connecting, so as to the classifying rationally interior space, improve its integral space utilization ratio, therefore set
Counting out a kind of new cross tube concrete column has important reference significance to engineering practice.
The content of the invention
The purpose of the present invention is to design a kind of simple in construction, easy construction, with preferable bearing capacity and anti-seismic performance,
And the splicing multi-chamber cross tube concrete column of building structure inner space utilization rate can be effectively improved.
The technical scheme is that, one kind splicing multi-chamber cross tube concrete column by rectangular steel pipe, U-shaped steel,
Concrete and weld seam are constituted.Distinguish outside weld U-shaped steel in the rectangular steel pipe long side direction, form three chambers, and in each chamber
Indoor casting concrete.
The working mechanism of the present invention is that the present invention is a kind of splicing multi-chamber cross tube concrete column, can be according to institute
Actual requirement is needed to design the size of rectangular steel pipe and both sides U-shaped steel, to meet the preferable connection in space with wall.Its
Steel pipe plays good effect of contraction to core concrete, concrete material nature is improved, i.e., intensity is carried
Height, plasticity and toughness properties are greatly improved.Simultaneously as concrete and square in the presence of concrete, especially both sides U-shaped steel
Concrete can be good at interaction in the middle part of shape steel pipe, and mutually restriction can slow down or prevent rectangle under pressure
Larger local buckling occurs in the middle part of steel pipe walls.

In figure：1- rectangular steel pipes, 2-U shape steel, 3- concrete, 4- weld seams.
Embodiment
The section form of the present invention is as shown in Figure 2.
It is a kind of special-shaped steel pipe concrete simple in construction, use flexibly to splice multi-chamber cross tube concrete column
Post.It is mainly made up of rectangular steel pipe (1), U-shaped steel (2), concrete (3) and weld seam (4).The mode of construction is in the square
The long side direction of shape steel pipe (1) relative welding U-shaped steel (2) outward, forms three chambers, and pours into each chamber coagulation scholar
(3), use vibrating spear side to shake in casting process to ensure that coagulation scholar perfusion is uniform, closely knit., can basis among Practical Project
The size of required actual requirement design rectangular steel pipe and both sides U-shaped steel, to meet the preferable connection with construction wall, so that gram
The drawbacks of indoor wall connection caused when existing side, concrete-filled circular steel tube column and wall connecting has some setbacks is taken, can be effectively improved
Indoor overall utilization rate.
Beneficial effects of the present invention
(1) multi-chamber cross tube concrete column is spliced, not only with general bearing capacity of concrete-filled steel tube height, construction party
Just the advantages of, fire resistance is good, and its both sides U-shaped steel be designed to constrain well in the middle part of rectangular steel pipe, can be more preferable
Slow down or prevent that larger flexing occurs in the middle part of rectangle steel tube wall under pressure.
(2) multi-chamber cross tube concrete column is spliced, making is simple, weld seam is less, speed of application is fast, saving of labor saves
Material, and design size is flexibly, and corresponding size adjustment can be carried out according to the actual requirements, can be preferably connected with construction wall, and then keep away
The indoor wall for exempting to cause during with wall connecting is uneven, has both improved the effective rate of utilization of the interior space, and people can be met again
To the demand of attractive in appearance and room arrangement.
Claims (3)
1. one kind splicing multi-chamber cross tube concrete column, it is characterised in that the steel core concrete column is by rectangular steel pipe
(1), two U-shaped steel (2), concrete (3) and weld seam (4) are constituted；Described two U-shaped steel are by weld seam in rectangle steel pipe range side side
To relative welding, three chambers, and the casting concrete in each chamber are formed.
2. splicing multi-chamber cross tube concrete column according to claim 1, it is characterised in that two U-shaped steel welderings
Two positions corresponding in the middle part of rectangular steel pipe are connected on, to ensure the symmetry of structure.
3. splicing multi-chamber cross tube concrete column according to claim 1, it is characterised in that rectangular steel pipe and two
The individual big I of U-shaped steel dimensions is designed according to the actual requirements, flexible layout.
