Definitions

  • This invention relates to a concrete filled tube column and a method of constructing the same, the concrete filled tube column constituting, for example, a part of a building structure, such as a column and a pile.
  • FIGS. 1 to 3 show an example of a conventional concrete filled tube column constituting a part of a building structure.
  • This column 20 is made of a steel outer tube 22 within which concrete is filled to form a concrete core 24.
  • the outer tube 22 includes a plurality of tube bodies 26, and a plurality of joint tubes 28. Each joint tube 28 coaxially interconnects two adjoining tube bodies 26.
  • the beams 30 of the building structure are welded to the outer face of each joint tube 28 so that an axial load is transmitted from the beams 30 to the outer tube 22.
  • a pair of vertically spaced parallel inner flanges 32 are circumferentially welded on the inner face of each joint tube 28, and project radially inward into the concrete core 24 to transmit the axial load from the outer tube 22 to the core 24.
  • the axial compressive strength of the concrete core 24 is enhanced by the lateral confinement of the outer tube 22, and thereby it is possible to considerably reduce the cross-sectional area of the column in comparison with the cross-sectional area of a conventional concrete column without an outer tube.
  • the charging of the concrete may be stopped every time the concrete is filled in the outer tube 22 up to the level of one of the inner flanges 32. After the charged concrete is hardened, concrete charging may be resumed until the concrete is filled up to the next inner flange 32.
  • a process of concrete charging considerably lengthens the construction period of the column 20.
  • a structural filler filled steel tube column including: a steel tube having an inner face and an outer face; a core made from the structural filler disposed within the steel tube; a separating layer, interposed between the inner face of the steel tube and the core, for separating the core from the inner face of the steel tube so that the steel tube is not bonded to the core; and an inner flange circumferentially mounted on the inner face of the steel tube to project radially inwardly for transmitting an axial load, applied on the steel tube, to the core.
  • EP-A-0218313 leaves a number of problems to be solved.
  • the thickness of the inner flange is large so that the inner flange can withstand the axial load. Accordingly, press working requires a very large force. Therefore, the manufacturing cost of producing the co-axial joint tube is high and production is difficult.
  • Another object of the present invention is to provide a concrete filled tube column of which joint portion connected to the beams of the structure, does not have stiffener protruding outward but has excellent mechanical strength.
  • Still another object of the present invention is to provide a method of constructing the concrete filled tube column which prevents the concrete core from developing either air spaces or rock pockets without lengthening the construction period.
  • a further object of the present invention is to provide a method of constructing the concrete filled tube column which reliably maintains the compressive strength of the column.
  • a further object of the present invention is to provide a precast structural tube for use in the concrete filled tube column, which prevents the concrete core from having either air spaces or rock pockets.
  • an aspect of the present invention is directed to a concrete filled tube column which includes: an outer tube connected to beams of the structure so that an axial load is transferred from the beams and applied to the outer tube, the outer tube consisting of a plurality of tube pieces coaxially disposed in series, the tube pieces having substantially equal transverse inner sizes; a concrete core disposed within the outer tube; and a tubular member, coaxially fitting within each of the tube pieces, for transferring the axial load from the outer tube to the concrete core.
  • the tubular member has a constant transverse outer size and a lower end portion.
  • the lower end portion of the tubular member has a first inner peripheral face tapering upward so that the transverse inner size at the lower end of the tubular member is equal to the transverse inner size of each of the tube pieces.
  • the tapering inner peripheral face allows air thereunder to flow upward smoothly therealong, and thus preventing the generation of the air spaces under the tubular member.
  • the tapering inner peripheral face enables the concrete to smoothly move therealong and to come into the space directly under the tubular member. As a result, the generation of air spaces or rock pockets are prevented.
  • the tubular member may include: a radially inwardly projecting first inner flange peripherally mounted on the inner face of each of the tube pieces; and a concrete layer peripherally disposed on the inner face of each of the tube pieces.
  • the concrete layer has a first tubular portion, that is, the lower end portion of the tubular member positioned under the first inner flange in such a manner that the first tubular portion is in direct contact with the entire lower side of the first inner flange.
  • the concrete layer may further include a second tubular portion positioned above the first inner flange in such a manner that the second tubular portion is in direct contact with the entire upper side of the first inner flange.
  • the second tubular portion has a second inner peripheral face tapering downward so that the transverse inner size at the upper end of the tubular member is equal to the transverse inner size of each of the tube pieces.
  • the tubular member may be made of steel and integrally formed with each of the tube pieces.
  • the precast structural tube includes: a tube piece having first and second ends; a radially inwardly projecting first inner flange mounted on the inner face of the tube piece, the first side being closer to the first end of the tube piece than the second side; and a concrete layer peripherally disposed on the inner face of the tube piece.
  • the concrete layer includes a first tubular portion concentric with the tube piece.
  • the first tubular portion has a first inner peripheral face.
  • One of the opposite ends of the first tubular portion is in direct contact with the entire first side of the first inner flange.
  • the first inner peripheral face of the first tubular portion tapers toward the second end of the tube piece so that the transverse inner size at the other end of the first tubular portion is equal to the transverse inner size of the tube pieces.
  • Still another aspect of the present invention is directed to a method of constructing a concrete filled tube column.
  • a plurality of the precast structural tubes are prepared.
  • one of the prepared precast structural tubes is erected with the second end of the tube piece positioned above the first end of the tube piece.
  • Concrete is placed within the erected precast structural tube to form a concrete core within the structural tube.
  • the beams of the structure are connected to the erected precast structural tube.
  • Another precast structural tube is coaxially connected to the upper end of the erected precast structural tube, whereby said another structural tube is erected on the lower adjoining structural tube. Thereafter, the above-mentioned steps from the concrete-placing step to the tube-connecting step are repeated a plurality of times.
  • FIGS. 4 to 11 wherein like reference characters designate corresponding parts throughout several views, and descriptions of the corresponding parts are omitted after once given.
  • FIG. 4 shows a concrete filled tube column according to the present invention, which is erected on a foundation 40 and constitutes a part of a building structure.
  • This column has an outer tube 42 in which concrete is filled to form a concrete core 44.
  • the outer tube 42 consists of a plurality of round steel tube pieces 46 coaxially joined in series.
  • Each of the tube pieces 46 includes a joint tube 48 and a tube piece body 50 which is coaxially joined to the lower end of the joint tube 48.
  • a plurality of bracket members in the form of H-steel bars 52 are welded to the outer face of the joint tube 48 so as to project radially outward from the outer face, and interconnect the joint tube 48 with beams 54 of the building structure.
  • Each H-steel bar 52 consists of upper and lower flange portions 56 and 58 and a web portion 60 interconnecting the upper and lower flange portions 56 and 58 (see FIG. 5).
  • a tubular member 62 fits coaxially in the joint tube 48 and projects radially inward into the concrete core 44 in order to transfer the axial load from the joint tube 48 to the core 44.
  • This tubular member 62 consists of: a pair of vertically spaced parallel inner flanges 64 and 66 circumferentially welded to the inner face of the joint tube 48; and a concrete layer 68 made of a high strength concrete circumferentially disposed on the inner face of the joint tube 48.
  • Each of the inner flanges 64 and 66 is of a disk-like configuration having a central aperture and protrudes radially inward from the inner face of the joint tube 48.
  • the upper inner flange 64 is positioned at the same level as the upper flange portions 56 of the bracket members 52, while the lower inner flange 66 is positioned at the same level as the lower flange portions 58 of the bracket members 52.
  • the concrete layer 68 consists of three cylindrical portions, namely, first, second and third portions 70, 72 and 74.
  • the first portion 70 is positioned under the lower inner flange 66 in such a manner that the upper end of the first portion 70 is in direct contact with the entire lower side of the first inner flange 66.
  • This first portion 70 has an inner peripheral face 71 tapering upward so that the inner diameter at the upper end of the first portion 70 is generally equal to the inner diameter of the lower inner flange 66 and the inner diameter at the lower end of the first portion 70, i.e., the lower end of the tubular member 62 is generally equal to the inner diameter of the joint tube 48.
  • the tapering angle ⁇ 1 of the inner peripheral face 71 with respect to the axis of the joint tube 48 is, preferably, in the range of 45° to 60°.
  • the second portion 72 extends between the upper and lower inner flanges 64 and 66. This second portion 72 has an inner diameter generally equal to the inner diameters of the upper and lower inner flanges 64 and 66.
  • the third portion 74 is positioned above the upper inner flange 64 in such a manner that the lower end of the third portion 74 is in direct contact with the entire upper side of the upper inner flange 64.
  • This third portion 74 has an inner peripheral face 75 tapering downward so that the inner diameter at the lower end of the third portion 74 is generally equal to the inner diameter of the upper inner flange 64 and the inner diameter at the upper end of the third portion 74, i.e., the upper end of the tubular member 62 is generally equal to the inner diameter of the joint tube 48.
  • the tapering angle ⁇ 2 of the inner peripheral face 75 with respect to the axis of the joint tube 48 is, preferably, in the range of 45° to 60°.
  • the high strength concrete forming the concrete layer 68 has a compressive strength higher than the compressive strength of the concrete which forms the concrete core 44.
  • a separating layer 76 is interposed between the concrete core 44 and the inner face of each tube piece 46 so that the core 44 is not bonded to the inner face of each tube piece 46.
  • This separating layer 76 is made of a material such as asphalt, oil, grease, paraffin wax, petrolatum, synthetic resin and paper.
  • the thickness of the separating layer 76 is such that it provides a viscous slip to the concrete core 44. In asphalt, the thickness is about 20 to 100 ⁇ m.
  • the tube piece body 50 consists of upper and lower tubular sections 78 and 80.
  • each of the upper and lower sections 78 and 80 are axially spaced apart from each other so that axial stress reducing means in the form of a ring-shaped gap 82 is formed between the upper and lower sections 78 and 80.
  • the length of each of the upper and lower sections 78 and 80 is such that the gap 82 is positioned at the intermediate portion, that is, the inflection point of moment of the tube piece body 50. Since the separating layer 76 allows axial movement of each tube piece 46 relative to the core 44, the gap 82 varies its axial width W1 when each tube piece 46 is subjected to the axial load which is transmitted from the beams 54 of the building structure. Accordingly, an axial stress which develops in each tube piece 46 is reduced by the gap 82.
  • the concrete core 44 is subjected to considerably more axial stress than the tube pieces 46 since the axial load applied to each tube piece 46 is transmitted to the core 44 via the upper and lower inner flanges 64 and 66 and the concrete layer 68.
  • the outer tube 42 which is under considerably less stress than the core 44, provides the core 44 with sufficient lateral confinement, thereby effectively enhancing the axial compressive strength of the column.
  • FIGS. 6 to 9 show a process for constructing the concrete filled tube column in FIG. 4.
  • a plurality of precast structural tubes 84 are prepared in a factory.
  • One of the precast structural tubes 84 is shown in FIG. 6.
  • This structural tube 84 is manufactured in the following way: Three joint tubes 48 and three tube piece bodies 50 are prepared. Then, as shown in FIG. 7, the H-steel bars 52 are welded to the outer face of each of the prepared joint tubes 48, and the upper and lower inner flanges 64 and 66 are welded to the inner face of each of the prepared joint tubes 48. Thereafter, the concrete layer 68 is formed on the inner face of each joint tube 48 as shown in FIG. 8.
  • This concrete layer 68 is formed by rotating the joint tube 48 slowly about its axis, and by manually spreading a high strength concrete on the inner face of the joint tube 48 so that the tapering inner peripheral faces 71 and 75 are formed respectively at the first and third portions 70 and 74 of the concrete layer 68.
  • reinforcements may be provided along the inner face of the joint tube 48 to facilitate the application of the concrete.
  • the concrete may be placed between the inner surface of the joint tube 48 and a cylindrical formwork which is detachably fixed to the inner face of the joint tube 48.
  • the concrete layer 68 is formed by centrifugal molding.
  • a pair of hollow truncated conical frameworks 86 are detachably fixed to the inner face of the joint tube 48 as shown by a phantom line in FIG. 8.
  • the joint tube 48 is laid on a rotation machine in such a manner that the axis of the joint tube 48 extends substantially horizontally, and then the joint tube 48 is rotated about its axis at a high speed. Subsequently, a predetermined amount of high strength concrete is placed between the formworks 86. As a result, the concrete placed in the joint tube 48 is subjected to a centrifugal force due to the rotation of the tube piece 48, thereby being spread throughout the area between the frameworks 86 and forming the concrete layer 68.
  • a clearance 88 may be formed between each framework 86 and the corresponding inner flange so that the concrete between the inner flanges 64 and 66 flows through the clearance 88 into the frameworks 86 during the rotation of the joint tube 48.
  • through holes may be formed in the inner flanges 64 and 66 so as to allow the concrete to flow into the frameworks 86.
  • the three joint tubes 48 are concentrically welded respectively to the upper ends of the three tube piece bodies 50 to form three tube pieces 46.
  • three tube pieces 46 are coaxially joined in series to form the precast structural tube 84.
  • the concrete layer 68 is formed after the welding of the inner flanges 64 and 66 and the H-steel bars 52 to the joint tube 48, the concrete layer 68 is not subjected to the heat due to the welding, and thereby the deterioration of the concrete layer 68 is prevented.
  • the precast structural tubes manufactured as mentioned above are transported from the factory to a construction site, and there, one of the precast structural tubes 84 is erected on the foundation 40. Subsequently, as shown in FIG. 9, concrete is charged into the erected precast structural tube 84 by using, for example, a tremie 90 (which is a concrete-supplying pipe for conveying concrete) to form the concrete core 44. As the top face of the concrete approaches the inner peripheral face 71 of the concrete layer 68, air around the tapering inner peripheral face 71 flows upward smoothly along the inner peripheral face 71, and therefore the space under the inner peripheral face 71 is completely filled with the charged concrete.
  • a tremie 90 which is a concrete-supplying pipe for conveying concrete
  • each of the tube piece bodies 50 is separated into the upper and lower sections 78 and 80 by using a suitable cutter so that the gap 82 is formed between the upper and lower sections 78 and 80.
  • the beams 54 of the building structure are joined respectively to the H-steel bars 52 of the precast structural tube 84, and then, another precast structural tube 84 is coaxially joined to the upper end of the concrete filled precast structural tube 84. Thereafter, the above-mentioned steps from the concrete-charging step to the precast tube-joining step are repeated predetermined times, which results in the construction of the concrete filled tube column.
  • a precast structural tube having less than or more than three tube pieces 46 may be used for constructing the concrete filled tube column.
  • another first portion 70 and another third portion 74 may be formed respectively under the upper inner flange 64 and above the lower inner flange 66.

This tube piece body consists of a hollow cylindrical cement matrix and a high strength carbon filament which is embedded within the cement matrix in such a manner that the carbon filament forms a coil coaxial with the cement matrix.
  • Such a tube piece body is prepared by impregnating the carbon filament with a cement paste including cement particles of a particle size smaller than the diameter of the carbon filament and by forming the carbon filament into a cylindrical configuration.
  • This fiber reinforced concrete tube piece body has a Young's modulus substantially equal to the Young' modulus of the concrete core 44, thereby providing the concrete core 44 with a sufficient lateral confinement even though neither the separating layer 76 nor stress reducing means 82 is disposed on the tube pieces.
