Abstract

The utility model relates to a concrete component, in particular to a steel pipe concrete special-shaped column used in civil engineering. The steel pipe concrete special-shaped column is formed by a plurality of rectangular steel pipe and concrete filled in the steel pipes; the rectangular steel pipes are connected by welding technique, the rectangular steel pipes can be welded in to special-shaped column with different section according to different demand, and the rectangular steel pipe is filled with concrete. The utility model is the main component of high building frame structure, and has the advantages of high bearing ability, high rigidity, light weight, good plasticity and tenacity, good shock resistant and anti-fatigue properties, and good seism resistant property.

Description

Steel pipe concrete profiled pile

Technical field

The utility model relates to a kind of concrete component, particularly relates to a kind of steel pipe concrete profiled pile that is used for civil engineering.

Background technology

At present, frame column as the main member of frame construction is generally common reinforced concrete post, has promptly tied up reinforcing cage earlier, has propped up template again, last fluid concrete, make this traditional reinforced concrete post exist long in time limit, difficulty is big, inefficient shortcoming.China's utility model patent has provided " a kind of reinforced concrete post " after improving for No. 03248845.9, comprise precast member for reinforcing bar concrete, reinforcing bar, reinforced concrete post is by polylith steel concrete tubular prefabricated units, longitudinal reinforcement network for location sheet, longitudinal reinforcement is formed, polylith steel concrete tubular prefabricated units are overlapped into the post mould, the longitudinal reinforcement network for location sheet that adapts with tubular prefabricated units inner chamber is set between adjacent steel reinforced concrete tubular prefabricated units seam, longitudinal reinforcement interts in longitudinal reinforcement network for location slice graticule, serial connection polylith steel concrete tubular prefabricated units, concreting in the superimposed post mould cavity of steel concrete tubular prefabricated units finally becomes reinforced concrete post again.Though the shortcoming that the reinforced concrete post after this improvement has existed when tentatively having overcome conventional steel reinforced concrete column production can not satisfy the more and more higher requirement of high-rise building to the use concrete structure.For this reason, people develop novel concrete structure again, for example United States Patent (USP) provides for No. 3051161 uses the concrete filling steel pipe, cover girder steel with what the encased structures technical scheme that increases compressive strength and United States Patent (USP) provided for No. 3516213 with concrete, to increase the steel reinforced concrete structure technical scheme of its fire line.Often greater than the thickness of body of wall, in use, the partly phenomenon of outstanding body of wall of pillar appears to the sectional dimension of frame column in indoor meeting, thereby has influenced indoor space and use but above technical scheme can't solve.For addressing this problem, China's utility model patent has provided " a kind of novel steel tube concrete column " for No. 99236299.7, wherein being used for the concrete steel pipe of filling is the special-shaped thin wall steel pipe, be provided with binding bar on each limit of special-shaped thin wall steel pipe, described special-shaped thin wall steel pipe can be square, L shaped or T shape thin-wall steel tube, the minimum length of side 〉=the 150mm of special-shaped thin wall steel pipe, wall thickness 〉=8mm; The spacing that binding bar is set is 100~200mm; The slenderness ratio of the post ratio of smallest cross-sectional width (length with)≤30.Though this steel core concrete column has solved the single problem of existing concrete filled steel tube post shapes, exist binding bar need be set, construction has the shortcoming of inconvenience more.

Summary of the invention

It is a kind of by several rectangular steel pipes and the steel pipe concrete profiled pile that concrete constituted that is filled in it that are welded into abnormity that the purpose of this utility model is to provide, its section form changes with the relation of post and wall, enrich the section form and the research contents of steel core concrete column, improved the shock resistance of steel core concrete column.

The purpose of this utility model is achieved through the following technical solutions:

Steel pipe concrete profiled pile is made of several rectangular steel pipes and the concrete that is filled in it, is welded to each other together fill concrete in the heterogeneous column of rectangular steel pipe one-tenth different cross section capable of being combined, rectangular steel pipe between its rectangular steel pipe.

Advantage of the present utility model and effect are:

1. the utility model is welded by several rectangular steel pipes, binding bar need be set between steel pipe, reduces difficulty of construction;

2. can reduce the sectional dimension of post behind the choose reasonable steel pipe, steel pipe skeleton can provide interim support when construction, accelerate speed of application;

3. because the existence of steel pipe has improved the ductility of post, improve the bearing capacity of post, be beneficial to the earthquake zone seismic design.

4. steel pipe concrete profiled pile can reduce the partly phenomenon of outstanding body of wall of pillar in use, increases indoor space.

Description of drawings

Fig. 1 is that the cross section that the utility model is made up of 4 rectangular steel pipes is the steel pipe concrete profiled pile schematic diagram of " ten " font structure;

Fig. 2 is that the cross section that the utility model is made up of 3 rectangular steel pipes is the steel pipe concrete profiled pile schematic diagram of "T"-shaped structure;

Fig. 3 is that the cross section that the utility model is made up of 2 rectangular steel pipes is the steel pipe concrete profiled pile schematic diagram of " L " shape structure.

The specific embodiment

With reference to the accompanying drawings structure of the present utility model is elaborated.

The used steel pipe of steel pipe concrete profiled pile is to be welded by several square steel pipes, fill concrete constitutes steel pipe concrete profiled pile in steel pipe again, the abnormal shape of indication in the utility model, be to instigate the section form of steel pipe concrete profiled pile to change with the body of wall change of shape, needed different shape in the time of can being arranged in the body of wall according to steel pipe concrete profiled pile, and change the formed shape of its cross section, specifically with cross, T shape and L shaped be example.

As shown in Figure 1, four rectangular steel pipes are welded into the hetermorphiscal column that the cross section is a decussate texture, concreting in four rectangular steel pipes makes four rectangular steel pipes and concrete constitute an integral body again, and promptly cross section is the steel pipe concrete profiled pile of decussate texture.

As shown in Figure 2, three rectangular steel pipes are welded into the hetermorphiscal column that the cross section is a T shape structure, concreting in three rectangular steel pipes makes three rectangular steel pipes and concrete constitute an integral body again, and promptly cross section is the steel pipe concrete profiled pile of T shape structure.

As shown in Figure 3, two rectangular steel pipes are welded into the hetermorphiscal column that the cross section is L shaped structure, concreting in two rectangular steel pipes makes two rectangular steel pipes and concrete constitute an integral body again, and promptly cross section is the steel pipe concrete profiled pile of L shaped structure.

The utility model need not be provided with binding bar between steel pipe, can reduce difficulty of construction, accelerates speed of application.

Claims (1)

1. steel pipe concrete profiled pile is made of several rectangular steel pipes and the concrete that is filled in it, it is characterized in that being welded to each other between the rectangular steel pipe together fill concrete in the heterogeneous column of rectangular steel pipe one-tenth different cross section capable of being combined, rectangular steel pipe.
