Description
- The present invention relates to a composite structure formed by integrally joining a steel member and a concrete-based member at the time of constructing an architectural structure, a civil engineering structure or the like.
- Conventionally, a composite structure which is formed by integrally joining a steel member and a concrete-based member has been popularly used in fields such as architectural structures and civil engineering structures. As the composite structure generally pertaining to the present invention in the same field, for example, there has been known a
composite structure 180 which usesstuds 181 as shown in FIG. 15 and FIG. 16, acomposite structure 190 which uses a perforated steel-platedowel connection member 191 as shown in FIG. 17 and FIG. 18 or the like. - In the
composite structure 180 shown in FIG. 15 and FIG. 16, a plurality ofstuds 181 are welded to an upper surface of asteel frame beam 182 which constitutes a steel member in an erected manner at predetermined intervals, and a layer-like concrete-basedmember 183 is formed on an upper surface of thesteel frame beam 182 in a state where thesestuds 181 are embedded in the concrete-basedmember 183. - In the
composite structure 190 shown in FIG. 17 and FIG. 18, the strip-shaped perforated steel-platedowel connection member 191 in which a plurality of throughholes 191 are formed at predetermined intervals is welded to an upper surface of asteel frame beam 192 which constitutes a steel member in the form of ribs. A layer-like concrete-basedmember 193 is formed on an upper surface of thesteel frame beam 192 in a state where the perforated steel-platedowel connection member 191 is embedded in the concrete-basedmember 193. - On the other hand, to increase adhesiveness between a placing frame and concrete, there has been proposed a technique where through holes are formed in a substrate which is a raw material for forming the placing frame by burring working so that a plurality of small irregular projections are formed on peripheries of the through holes (see
Patent Document 1, for example). -
- Patent Document 1: Japanese Patent Laid-open Publication No. 10-102503
- The
studs 181 which constitute thecomposite structure 180 shown in FIG. 15 and FIG. 16 exhibit the largest shearing force along accompanying with the displacement deformation and hence, thestuds 181 have been popularly used in the fields of architectural and civil engineering structures. However, in thecomposite structure 180, to acquire high shear strength and high initial rigidity, it is necessary to join a large number ofstuds 181 to the upper surface of thesteel frame beam 182 and hence, a wide mounting space is necessary for arranging thestuds 181. Accordingly, thestuds 181 are not suitable for a joining portion on which a stress is concentrated in the composite structure which requires high initial rigidity. - On the other hand, in the
composite structure 190 shown in FIG. 17 and FIG. 18, the displacement between the perforated steel-platedowel connection member 191 and the concrete-basedmember 193 is prevented or suppressed due to the shear resistance of concrete filled into the throughholes 191a formed in the perforated steel-platedowel connection member 191 and hence, the perforated steel-platedowel connection member 191 has high rigidity compared to thestuds 181 shown in FIG. 15 and FIG. 16 thus possessing advantages such as an excellent fatigue characteristic and favorable work executing efficiency. However, in the technical field of the present invention, there has been a demand for the further improvement of shear strength, and it is the current situation that thecomposite structure 190 shown in FIG. 17 and FIG. 18 cannot also satisfy such a demand. - On the other hand, in the placing frame described in
Patent Document 1, as a means for increasing adhesiveness of a joining portion between the placing frame and concrete, a plurality of through holes having small irregular projections are formed in the substrate by burring working. However, these small projections are formed with irregular shapes along the peripheries of the through holes and hence, it is indefinite whether or not these small projections have a function of increasing shear strength. - Accordingly, one or more embodiments of the present invention provide a composite structure which can largely increase a displacement prevention function, shear strength and rigidity at a joining portion between a steel-frame-based member and a concrete-based member and, at the same time, can also exhibit excellent work executing efficiency.

FIG. 18 is a cross-sectional view taken along a line Y-Y inFIG. 17 . - Hereinafter, the
composite structures FIG. 1 toFIG. 14 . - The
composite structure 10 shown inFIG. 1 toFIG. 4 includes: a flat-plate-likeshear resistance member 3 joined to asurface 1 a of a flat-plate-like substrate 1 in an erected manner like a partitioning screen byfillet welds 2; and a concrete-basedmember 4 formed on thesurface 1 a of thesubstrate 1 in a state where theshear resistance member 3 is embedded in the concrete-basedmember 4. A plurality of throughholes 5 are formed in theshear resistance member 3, and projectingrim portions 6 are formed such that the projecting rim portions project toward the outside of onesurface 3 a of theshear resistance member 3 from inner peripheries of the throughholes 5. The plurality of throughholes 5 have a circular shape, and the projectingrim portions 6 have a short cylindrical shape which is continuous with the inner periphery of thethrough hole 5. Although both thesubstrate 1 and theshear resistance member 3 are formed of a steel plate, a material for forming thesubstrate 1 and theshear resistance member 3 is not limited to a steel plate. -
FIG. 4 is a cross-sectional view with a part omitted taken along a line C-C inFIG. 2 , and shows a state where the concrete-basedmember 4 and thefillet welds 2 which constitute thecomposite structure 10 are omitted. As shown inFIG. 4 , four throughholes 5 are formed in theshear resistance member 3 at fixed intervals along the longitudinal direction of theshear resistance member 3. The projectingrim portion 6 formed on each throughhole 5 projects toward the outside of onesurface 3 a of theshear resistance member 3. An inner diameter of the throughhole 5, the number of throughholes 5, intervals at which the throughholes 5 are formed and the like are not particularly limited. - As shown in
FIG. 1 , in thecomposite structure 10, the displacement between theshear resistance member 3 and the concrete-basedmember 4 is prevented by a shear resistance of the concrete-basedmember 4 filled in the throughholes 5. Further, the projectingrim portions 6 formed on the throughholes 5 and the concrete-basedmember 4 disposed in the vicinity of the projectingrim portions 6 also exhibit shear resistance force and a displacement prevention function and hence, high rigidity and shear strength of thecomposite structure 10 can be largely increased. Further, thefillet welds 2 for joining theshear resistance member 3 to thesurface 1 a of thesubstrate 1 can be formed in a factory or the like in advance and, thereafter, thecomposite structure 10 can be conveyed to a construction site. Accordingly, it is possible to avoid a welding work at a construction site so that thecomposite structure 10 exhibits favorable work executing efficiency. - Further, the projecting
rim portion 6 is formed on the throughhole 5 and hence, the rigidity of theshear resistance member 3 per se is increased so that theshear resistance member 3 is minimally deformed. Accordingly, the formation of the projectingrim portion 6 can improve the handling of theshear resistance member 3 at the time of conveying or storing, can effectively improve work executing efficiency, and can improve the strength of thecomposite structure 10. Further, since the rigidity of theshear resistance member 3 is improved, the deformation of theshear resistance member 3 due to a thermal effect at the time of forming thefillet welds 2 can be prevented. - The through
hole 5 formed in theshear resistance member 3 can be also used as an insertion hole. That is, a wire rope or a shackle is inserted into the throughhole 5 at the time when a steel material to which theshear resistance member 3 is joined is hoisted by a crane. A reinforcing bar can be inserted into the throughhole 5 formed in theshear resistance member 3. Accordingly, the throughholes 5 can be also used as spacers at the time of arranging reinforcing bars at a construction site of an architectural or civil engineering structure. - Although a working method for forming the projecting
rim portion 6 on the throughhole 5 is not particularly limited, the projectingrim portion 6 is formed on the throughhole 5 by burring working in this embodiment. Burring working is a working technique where an inner periphery of a prepared hole formed in a steel plate which is a material for forming theshear resistance member 3 is raised in the plate thickness direction of the steel plate using a punch and a die. Although thesubstrate 1 to which theshear resistance member 3 is joined has a flat plate-like shape, the shape of thesubstrate 1 is not limited to such a shape in thecomposite structure 10. Provided that theshear resistance member 3 can be joined to thesubstrate 1, any steel material such as an I-beam steel, an H-beam, a T-beam, an angle beam, a channel beam or a steel pipe, for example, can be used as thesubstrate 1. - As described previously, a reinforcing bar (not shown in the drawing) can be inserted into the through
hole 5 formed in theshear resistance member 3. Accordingly, thecomposite structure 10 may adopt the structure where one or a plurality of reinforcing bars (not shown in the drawing) are inserted into each throughhole 5, and the concrete-basedmember 4 is formed on thesurface 1 a of thesubstrate 1 in a state where theshear resistance member 3 and the reinforcing bars (not shown in the drawing) are embedded in the concrete-basedmember 4. Due to such a constitution, horizontal shearing force (shearing force in the direction parallel to thesurface 1 a of the substrate 1) can be shared by the reinforcing bars and hence, a deformation resistance is increased whereby thecomposite structure 10 can acquire excellent advantageous effects such as the increase of resistance force against floating of the concrete-basedmember 4. - Next, the
composite structures FIG. 5 toFIG. 9 . All ofFIG. 5 toFIG. 9 are cross-sectional views with a part omitted in the same manner as the above-mentionedFIG. 4 and hence, parts corresponding to the concrete-basedmember 4 and the fillet welds 2 shown inFIG. 1 are omitted. Further, in thecomposite structures FIG. 5 toFIG. 9 , constitutional parts having the same shape and function as the corresponding constitutional parts of thecomposite structure 10 shown inFIG. 1 are given the same symbols, and the repeated description of these parts is omitted. - The
composite structure 20 shown inFIG. 5 includes: twoshear resistance members 3 joined to asurface 21 a of a flat-plate-like substrate 21 in an erected manner like a partitioning screen by welds (not shown in the drawing); and a concrete-based member (not shown in the drawing) formed on thesurface 21 a of thesubstrate 21 in a state where theshear resistance member 3 is embedded in the concrete-based member. Twoshear resistance members 3 are arranged parallel to each other in a state where theother surfaces 3 b of theshear resistance members 3 from which projectingrim portions 6 formed on throughholes 5 do not project are made to face each other in an opposed manner. - In the
composite structure 20, twoshear resistance members 3 exhibit shear resistance force and a displacement prevention function respectively and hence, thecomposite structure 20 has the higher rigidity than thecomposite structure 10 whereby the shear strength can be further increased in thecomposite structure 20. - Next, the
composite structure 30 shown inFIG. 6 includes: twoshear resistance members 3 joined to asurface 31 a of a flat-plate-like substrate 31 in an erected manner like a partitioning screen by fillet welds (not shown in the drawing); and a concrete-based member (not shown in the drawing) formed on thesurface 31 a of thesubstrate 31 in a state where theshear resistance member 3 is embedded in the concrete-based member. Twoshear resistance members 3 are arranged parallel to each other in a state where one surfaces 3 a of theshear resistance members 3 from which projectingrim portions 6 formed on throughholes 5 project are made to face each other in an opposed manner. In thecomposite structure 30, twoshear resistance members 3 exhibit shear resistance force and a displacement prevention function respectively and hence, thecomposite structure 30 has the higher rigidity than thecomposite structure 10 whereby the shear strength can be further increased in thecomposite structure 30. - Next, the composite structure 40 shown in
FIG. 7 includes: ashear resistance member 43 joined to a surface 41 a of a flat-plate-like substrate 41 in an erected manner like a partitioning screen by fillet welds (not shown in the drawing); and a concrete-based member (not shown in the drawing) formed on the surface 41 a of the substrate 41 in a state where theshear resistance member 43 is embedded in the concrete-based member.

The projecting directions of the projectingrim portions 6 formed on the throughholes 5 arranged adjacent to each other are made 180 degrees different from each other. That is, with respect to the throughholes 5 arranged adjacent to each other, the projectingrim portion 6 formed on one throughhole 5 projects from afront surface 43 a of theshear resistance member 43, while the projectingrim portion 6 formed on the other throughhole 5 projects from aback surface 43 b of theshear resistance member 43. - Due to such a constitution, shear resistance force which the
shear resistance member 43 and the concrete-based member (not shown in the drawing) generate is made uniform between thefront surface 43 a and theback surface 43 b of theshear resistance member 43. Accordingly, such a constitution can effectively enhance the strength of the composite structure 40. - Next, the
composite structure 50 shown inFIG. 8 includes: twoshear resistance members 43 joined to asurface 51 a of a flat-plate-like substrate 51 in an erected manner like a partitioning screen by welds (not shown in the drawing); and a concrete-based member (not shown in the drawing) formed on thesurface 51 a of thesubstrate 51 in a state where theshear resistance member 43 is embedded in the concrete-based member. - In the
composite structure 50, twoshear resistance members 43 are joined to thesurface 51 a of thesubstrate 51 such that theshear resistance members 43 are arranged parallel to each other. Accordingly, theseshear resistance members 43 and the concrete-based member (not shown in the drawing) exhibit large shear resistance force and hence, the shear strength can be increased compared to the composite structure 40 shown inFIG. 7 . - Next, the
composite structure 60 shown inFIG. 9 includes: ashear resistance member 63 joined to asurface 61 a of a flat-plate-like substrate 61 in an erected manner like a partitioning screen by fillet welds (not shown in the drawing); and a concrete-based member (not shown in the drawing) formed on thesurface 61 a of thesubstrate 61 in a state where theshear resistance member 63 is embedded in the concrete-based member. A plurality of throughholes 65 are formed in theshear resistance member 63 along the longitudinal direction of theshear resistance member 63 at fixed intervals, and projectingrim portions 66 are formed on inner peripheries of each throughhole 65 such that the projectingrim portions 66 project outward from afront surface 63 a and aback surface 63 b of theshear resistance member 63 respectively. - In the
composite structure 60, the projectingrim portions 66 formed on the throughholes 65 are provided to both surfaces (front surface 63 a and back surface 63 b) of theshear resistance member 63 and hence, there is no difference between a front side and a back side of theshear resistance member 63. Accordingly, shear resistance force which theshear resistance member 63 and the concrete-based member (not shown in the drawing) exhibit is made uniform between thefront surface 43 a and theback surface 43 b of theshear resistance member 63 and hence, such a constitution is effective for increasing the strength of thecomposite structure 60. - The
composite structures FIG. 5 toFIG. 9 may adopt the structure where one or a plurality of reinforcing bars (not shown in the drawing) are inserted into each throughholes shear resistance members surfaces substrates shear resistance members - Next, the

The projectingrim portion 76 formed on the throughhole 5 projects from onesurface 73 a of the shear resistance member 73 (a contact surface with the concrete-based member 74). The plurality of throughholes 75 have a circular shape, and the projectingrim portion 76 has a short cylindrical shape and is continuously formed with an inner periphery of the throughhole 75. Although both shearresistance members 73 are formed using a flat-plate-like steel plate, a material for forming theshear resistance members 73 is not limited to the flat-plate-like steel plate, and a corrugated plate, a folded plate or the like can be used for forming theshear resistance members 73. - Due to the provision of the through
holes 75 and the projectingrim portions 76, thecomposite structure 70 can acquire a strong displacement prevention function at joining portions between the two steel-plate-madeshear resistance members 73 and the concrete-basedmember 74.
