Abstract

The utility model discloses a reinforcement structure of a concrete-filled steel tube column. The periphery of a steel tube is provided with a layer of jacket steel tube and the interlayer between the steel tube and the jacket steel tube is filled with concrete. By the reinforcement structure, the strength of the concrete-filled steel tube column can be enhanced and the plasticity and the toughness of the concrete-filled steel tube column can be improved.

Description

A kind of ruggedized construction of steel core concrete column

Technical field

The utility model relates to a kind of ruggedized construction of steel core concrete column.

Background technology

The advantage such as steel core concrete column has that bearing capacity height, anti-seismic performance are good, easy construction, fire resistance are good has been widely used in multilayer, high level and the super highrise building.

The highrise building floor is many, highly high, personnel concentrate, and its fire risk is larger than common building.Yet such as Fig. 1, Fig. 2 and shown in Figure 3, in the prior art, steel core concrete column 100 coats concrete columns 20 by steel pipe 10 and forms, i.e. fluid concrete and forming in the steel pipe 10.In case breaking out of fire, because steel pipe 10 directly contacts burning things which may cause a fire disaster, and concrete column 20 directly contacts with steel pipe 10, and therefore, the steel and the concrete mechanical property that form steel core concrete column 100 reduce, and cause the depression of bearing force of steel core concrete column.

For the district that provides fortification against earthquakes, in case after meeting with earthquake, the intensity of steel core concrete column 100, rigidity and displacement Ductility all can reduce, can't again bear following geological process.

In addition, in Practical Project, owing to the reasons such as storey-adding reconstruction cause steel core concrete column 100 bearing capacity and stiffness not enough, need to reinforce.

The utility model content

The purpose of this utility model is to provide a kind of and improves intensity and improve plasticity and the ruggedized construction of the steel core concrete column of toughness properties.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of ruggedized construction of steel core concrete column arranges one deck outer steel pipe in the steel pipe periphery, and between the interlayer of steel pipe and outer steel pipe fill concrete.

Further, the arranged outside bracing means of steel pipe.

Further, bracing means is riser or the peg of welding.

Further, outer steel pipe overlaps with the geometric center of steel tube section, and outer steel pipe is consistent with the steel pipe shape.

After adopting such scheme, the utility model compared with prior art, it has following beneficial effect:

One, utilize steel pipe and the interaction of concrete bi-material when stressed, the intensity of steel core concrete column is improved, plasticity and toughness properties are greatly improved, outer steel pipe generation cripling can be avoided or delay to the concrete of filling between interlayer simultaneously, can guarantee giving full play to of its material property;

Two, under the parcel of fill concrete between the interlayer of outer steel pipe and steel pipe and outer steel pipe, steel core concrete column can effectively reduce inner temperature when meeting with fire effect, improves fire resistance;

Three, when cast was reinforced, outer steel pipe can also be as the template of fluid concrete, and short construction period and consolidation effect are good;

Four, in the steel pipe periphery one deck outer steel pipe is set, the cross section of reinforcing is little, does not affect normal usage space, and saves cost.

Description of drawings

Fig. 1, Fig. 2 and Fig. 3 are three kinds of perspective view of prior art steel core concrete column;

Fig. 4, Fig. 5 and Fig. 6 are three kinds of perspective view of the present utility model;

Fig. 7 is that the utility model bracing means is the sectional drawing of riser;

Fig. 8 is that the utility model bracing means is the sectional drawing of peg.

Concrete 4.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is described in detail.

Consult Fig. 4 to shown in Figure 8, the ruggedized construction of a kind of steel core concrete column of announcement of the present utility model, steel core concrete column coats concrete column 2 by steel pipe 1 and forms; In steel pipe 1 periphery one deck outer steel pipe 3 is set, and between the interlayer of steel pipe 1 and outer steel pipe 3 fill concrete 4.

The arranged outside bracing means 11 of steel pipe 1, bracing means 11 can be riser or the peg of welding.The concrete 4 of filling between the interlayer of bracing means 11 reinforcement steel pipes 1 and steel pipe 1 and outer steel pipe 3 and the globality of outer steel pipe 3, thereby the bulk strength of reinforcement steel core concrete column.

Outer steel pipe 3 overlaps with the geometric center in steel pipe 1 cross section, and outer steel pipe 3 is consistent with steel pipe 1 shape, and namely outer steel pipe 3 is consistent with steel pipe 1 cross section, perhaps is all circle (as shown in Figure 4), perhaps be all square (as shown in Figure 5), perhaps be all rectangle (as shown in Figure 6).Outer steel pipe 3 steel are common or high-strength steel, and the concrete 4 of filling between the interlayer is ordinary concrete or high-strength, high performance concrete.

The utility model is when forming ruggedized construction, and outer steel pipe 3 is placed with steel core concrete column is concentric, forms interlayer between outer steel pipe 3 and the steel pipe 1; At the outside of steel pipe 1 welding riser or peg; Fill concrete 4 in interlayer, and the height of concrete 4 is equal with outer steel pipe 3 and steel pipe 1 end face.

The utility model can be applied to steel core concrete column and meet with the infringement that fire, earthquake etc. cause, perhaps because the concrete filled steel tube columns bearing capacity that the other reasonses such as storey-adding reconstruction cause and insufficient rigidity etc.

The above is preferred embodiment of the present utility model only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
