Description

  The present invention relates to a method for manufacturing a shape and a shape.

  For example, a profile used as a beam or a yoke of a forklift is formed in a cross-sectional H shape having a flange and a web so as to increase the strength. In recent years, in order to achieve weight reduction, a shape is formed of a light metal such as aluminum. On the other hand, it is required to further increase the strength of the shape by increasing the size of the object to be conveyed.

In order to increase the strength of the shape material, it is conceivable to increase the cross-sectional shape, but there is a limit to the increase in size due to the layout. In view of this, there has been devised a profile whose strength is increased by providing a reinforcing member having a strength higher than that of the profile body inside the profile having an H-shaped section (see, for example, Patent Document 1).
JP 2000-33446 A

  By the way, the shape material of patent document 1 inserts a reinforcing material in the ditch | groove formed in the shape material, and fixes a reinforcing material integrally to a shape material by brazing. In Patent Document 1, the shape member is provided on the outer peripheral edge of a sandwich panel formed by sandwiching a large number of core materials between a pair of surface plates. Since the brazing operation is performed, the fixing between the core material and the surface plate and the fixing between the shape member and the reinforcing material can be performed in a single brazing operation. Further, since the surface of the profile is covered with the surface plate, the reinforcing material fixed to the concave groove is not exposed, and an excellent appearance is obtained.

  However, brazing has a problem that temperature control is difficult and manufacturing is difficult, and that the size of the shape material that can be manufactured is limited by the size of the furnace. That is, as in Patent Document 1, when brazing is performed to sandwich and fix a large number of core materials between the surface plates, the shape member and the reinforcing material can be fixed efficiently at the same time. When the shape material is used alone, there is a problem that if the brazing is bothered, the size is limited and the production efficiency is deteriorated.

  Furthermore, in the profile of Patent Document 1, if it is used alone, there is a problem that the reinforcing material is exposed and the appearance is deteriorated.

Since it is not necessary to put in the furnace like the shape material of Patent Document 1, the size of the shape material is not limited, and the temperature management of the furnace is not necessary. Further, the lid plate is fixed integrally with the profile body by friction stirring, and the reinforcing material is not exposed to the profile surface, so that an excellent appearance with a clean surface can be obtained. Furthermore, since the plastic fluidized material fluidized by friction stirring is caused to flow into the gap between the reinforcing material and the groove, the fixing strength between the reinforcing material and the profile can be increased as compared with the prior art. The strength of can be increased.

  The invention according to claim 2 is the method for producing a profile according to claim 1, wherein the concave groove includes a widened portion that accommodates the lid plate in an opening portion thereof.

  According to such a method, since the lid plate is placed on the widened portion of the concave groove and the friction stir is performed in a stable state, the joining process can be easily performed and the accuracy of the shape can be improved.

  According to a third aspect of the present invention, a reinforcing member made of a material having a strength higher than that of the shape body is inserted into the hollow portion formed in the shape body, and the surface portion of the shape body corresponding to the hollow portion And a plastic fluidized material fluidized by frictional heat is caused to flow into the gap between the reinforcing material and the hollow portion.

  According to such an invention, as in the invention of claim 1, the size and shape of the shape material are not limited, and the effect of being able to be efficiently manufactured and having an excellent appearance can be obtained.

  The invention according to claim 5 is characterized in that the reinforcing material is constituted by a stranded cable formed by twisting together a plurality of wires mixed with carbon fibers. It is a manufacturing method of a shape material given in any 1 paragraph.

  According to such a method, by using the stranded cable, the surface area of the reinforcing material is increased, and the contact area between the reinforcing material and the plastic fluidizing material is further increased. Further, since the plastic fluid material flows into contact with the surface of the concavo-convex stranded cable, the reinforcing material is locked in the longitudinal direction, and the fixing strength between the reinforcing material and the profile is further increased.

  The invention according to claim 6 is characterized in that the shape body is made of an extruded shape made of aluminum, and manufacturing the shape according to any one of claims 1 to 5. Is the method.

  According to such a method, it is possible to easily manufacture a profile body having a complicated shape by simply cutting an extruded profile with an appropriate length. Moreover, since the extruded shape made of aluminum has high dimensional accuracy and is light in weight, it can be easily handled on site.

  In the invention according to claim 7, a reinforcing material made of a material having a higher strength than that of the shape body is inserted into the insertion portion formed in the shape body, and a gap portion between the reinforcement and the insertion portion. The shape material is characterized in that a plastic fluidized material fluidized by frictional heat of friction stirring is introduced into the material.

[First embodiment]
Next, the best first embodiment for carrying out the present invention will be described in detail with appropriate reference to the drawings. In the present embodiment, a method for manufacturing a profile and a profile according to the present invention will be described by taking as an example a case where a flange portion of a profile having an H-shaped cross section is reinforced.

  First, the configuration of the profile according to the present invention will be described. As shown in FIG. 1, a profile body 2 of a profile 1 according to the present embodiment is configured by an extruded profile made of aluminum or an aluminum alloy, and has a cross-section H composed of flanges 3 and 3 and a web 4. It has a letter shape.

  In the profile 1 according to the present embodiment, a material having a higher strength than the aluminum that is the profile body 2, specifically, the Young's modulus of aluminum (70.3) is formed in the insertion portion 5 formed in the flanges 3 and 3. (GPa)) is inserted a reinforcing material 20 made of a material having a higher Young's modulus, and the plastic fluidized material 7 fluidized by the frictional heat of friction stirring in the gap 6 between the reinforcing material 20 and the insertion portion 5 is formed. It is characterized by being inflow.

  The insertion portion 5 is formed so as to penetrate along the extrusion direction of the profile body 2 and has a substantially circular cross section. In the present embodiment, the insertion portion 5 is configured by being divided by a lower inner surface of a concave groove 10 to be described later and a lower surface of the lid plate 11.

  The reinforcing member 20 inserted into the insertion portion 5 is a rod-shaped member, and is constituted by a stranded wire cable formed by twisting together a plurality of wires 20a, 20a,. . The stranded cable (reinforcing material 20) is formed by mixing carbon fibers into a thermosetting resin such as an epoxy resin, compounding and curing the fibers to form the wires 20a, 20a, and twisting them together. It is a thing. In the present embodiment, for example, a total of seven wires 20a, 20a,..., One at the center and six around the periphery, are twisted together to form a stranded cable having an outer diameter of, for example, 12.5 mm. . This stranded cable has a Young's modulus of 137 (GPa) and is stronger than aluminum. The outer diameter and Young's modulus of the stranded cable are only examples, and the Young's modulus is higher than that of the profile body, and is appropriately selected according to the size of the profile body.

Moreover, in this embodiment, carbon fiber is mixed in thermosetting resin, such as an epoxy resin, and this is compounded, and the wire 20a is formed, However, It is not restricted to this. For example, a mixed powder prepared by mixing ceramic powder such as SiC and Al ₂ O ₃ with Al—Si—Mg—Cu alloy powder is subjected to hot isostatic pressing or cold isostatic pressing. Formed into billet shape by pressure method (Cold Isostatic Pressing), extruded and then age-hardened Al-Si-Mg-Cu alloy as matrix to produce wire with higher Young's modulus than profile body 2 However, this may be used as a reinforcing material. In addition, steel round bars such as S45C and SKD, and stainless steel round bars such as SUS303 and 304 may be used as a reinforcing material in the same shape. Alternatively, a plurality of these steel wires and stainless wires may be twisted together to form a stranded cable (reinforcing material).

  The plastic fluid 7 that has flowed into the gap 6 between the reinforcing member 20 and the insertion portion 5 flows into the recesses between the adjacent wires 20a and 20a along the irregularities on the outer peripheral surface of the stranded wire cable, and the stranded wire. The cable and the plastic fluidized material 7 are configured to mesh with each other. The plastic fluidized material 7 flows and fills a substantially half region on the surface 2a (see FIG. 3A) side of the profile body 2 of the gap 6. Needless to say, the plastic fluidizing material 7 may be filled in the entire gap 6 along the entire outer peripheral surface of the reinforcing material 20.

  Next, a method for manufacturing the profile 1 having the above-described configuration will be described.

  First, as shown in FIG. 2A, a profile body 2 having an H-shaped cross section composed of a flange 3 (shown only on one side in FIG. 2) and a web 4 is formed. The profile body 2 is constituted by an extruded profile of aluminum or aluminum alloy. The flange 3 is integrally formed with a concave groove 10 opened on the surface side during extrusion. The opening portion of the groove 10 includes a widened portion 12 that accommodates the lid plate 11 (see FIG. 3A). The widened portion 12 is formed continuously with the reinforcing material accommodating portion 13 on the bottom side of the concave groove 10. The reinforcing material accommodating portion 13 has a bottom surface 13a having a semicircular cross section at the bottom side half, and inner walls 13b and 13b parallel to each other at the opening side half. The inner side walls 13b and 13b are formed in a direction orthogonal to the surface 2a of the flange 3 of the profile body 2. The reinforcing material accommodating portion 13 has a width and height equivalent to the outermost peripheral diameter of the reinforcing material 20 (see FIG. 2B) made of a stranded wire cable, and is reinforced on the bottom side of the widened portion 12. It is comprised so that the whole material 20 can be accommodated.

  The widened portion 12 extends perpendicularly from the inner side walls 13b, 13b on both sides in the width direction of the reinforcing material accommodating portion 13 below the concave groove 10 (in parallel with the surface 2a of the flange 3 of the profile body 2). The support surfaces 12a and 12a are provided with side walls 12b and 12b orthogonal to the support surface 12a at both ends in the width direction of the support surfaces 12a and 12a. The support surfaces 12a and 12a are configured to support the cover plate 11 at both ends in the width direction.

  The concave groove 10 is formed continuously over the entire length of the profile body 2 in the extrusion direction. The concave grooves 10 are formed in a plurality of rows (four rows in this embodiment) at a predetermined interval in the width direction of the flange 3 and are parallel to each other.

  In the present embodiment, the concave groove 10 including the widened portion 12 is integrally formed when the profile body 2 is extruded, but the present invention is not limited to this. For example, a groove having no widened portion may be formed by an extruded profile, and the widened portion may be formed by known end milling or cutting. Furthermore, a profile body having no concave groove may be formed by an extruded shape, and the concave groove including the widened portion may be formed by known end milling or cutting.

  Next, as shown in FIG. 2B, the plurality of reinforcing members 20 are sequentially inserted into the respective concave grooves 10 from the surface 2 a side of the flange 3. At this time, the outermost peripheral portion of the reinforcing member 20 made of the stranded cable is in line contact with the bottom surface 13a of the reinforcing member accommodating portion 13 in a spiral shape. The reinforcing material 20 is completely accommodated in the reinforcing material accommodating portion 13, and the opening side end portion of the reinforcing material 20 is located on the bottom side of the support surface 12 a of the widened portion 12.

  Then, as shown to (a) of FIG. 3, the some cover plate 11 is inserted in the wide part 12 of the opening part of each concave groove 10 one by one. The lid plate 11 is made of the same kind of aluminum or aluminum alloy as the profile body 2, and has a width equivalent to the distance between the side walls 12 b and 12 b of the widened portion 12 and a thickness equivalent to the depth of the widened portion 12. It has. Accordingly, the side surfaces 11a and 11a on both sides in the width direction of the lid plate 11 are in surface contact with the side walls 12b and 12b of the widened portion 12 or face each other with a minute gap, and the surface 11b of the lid plate 11 It is flush with the surface 2a of the main body 2. And the butting | matching parts 15 and 15 of the profile main body 2 and the cover board 11 will be located in the width direction both ends of the cover board 11, respectively.

  Next, as shown in FIG. 3B, friction stir welding is sequentially performed along the abutting portions 15 and 15 of the shape body 2 at both ends in the width direction of the cover plate 11. Here, friction agitation refers to pressing the shape body 2 of the butting portion 15 and the base material of the cover plate 11 while rotating the cylindrical rotary tool 25 having a protrusion at the tip so as to penetrate the butting portion 15. The frictional heat is generated to soften the base material, and the surroundings of the butt portion 15 are plastically fluidized by the rotational force of the rotary tool 25 and kneaded to integrate the members.

  The rotary tool 25 is made of, for example, tool steel, and includes a cylindrical tool body 26 and a pin 27 that hangs down on a concentric axis from the center of the bottom surface. The pin 27 is formed in a tapered shape that becomes narrower toward the tip. Note that a plurality of small grooves (not shown) and screw grooves along the radial direction may be formed on the peripheral surface of the pin 27 along the axial direction thereof.

  When the friction stir is performed, the rotary tool 25 that rotates at high speed is pushed into each abutting portion 15 in a state where the shape body 2 and the cover plate 11 are restrained by a jig (not shown), and moved along the abutting portion 15. By the pin 27 rotating at high speed, the surrounding shape body 2 and the aluminum alloy material of the cover plate 11 are heated and fluidized by frictional heat. The fluidized material (plastic fluid 7) flows into the gap 6 between the reinforcing member 20 and the groove 10.

  At this time, the plastic fluid 7 that has flowed into the gap 6 adheres to the surface of the reinforcing member 20 and can fix the reinforcing member 20 and the profile body 2. In particular, in this embodiment, since the reinforcing member 20 is formed of a stranded cable, as shown in FIG. 4, the plastic fluid material 7 is along the irregularities on the outer peripheral surface on the opening portion side of the stranded wire cable. Then, it flows and hardens so as to enter the recess between the adjacent wire rods 20a, 20a, and the reinforcing member 20 is locked. The plastic fluidized material 7 also flows in the axial direction of the stranded cable and can also flow into the gap 6a formed by the bottom surface of the cover plate 11 and the wires 20a and 20a adjacent to each other. Therefore, the reinforcement member 20 is reliably restricted from moving in the circumferential direction and the axial direction (longitudinal direction), and the fixing strength between the profile body 2 and the reinforcement member 20 is greatly increased. As a result, the strength of the profile 1 can be reliably and efficiently increased.

  Moreover, since the widened part 12 which accommodates the cover plate 11 is formed in the opening part of the ditch | groove 10, the cover plate 11 is guided at the time of the insertion, is positioned easily, and is mounted in the widened part 12 Since the friction stir is performed in a stable state, it is easy to perform the friction stir processing, and the accuracy of the profile 1 can be improved.

  According to the shape manufacturing method and the shape 1 as described above, since the reinforcing material 20 is fixed to the shape body 2 by friction stirring, the butt portion 15 between the cover plate 11 and the shape body 2 is attached. It is only necessary to press the rotating tool 25 while rotating it, and the profile 1 can be efficiently manufactured by simple processing. Furthermore, since it is not necessary to put in the furnace like the shape of Patent Document 1 to manufacture the shape 1, the size of the shape 1 is not limited, and the temperature control of the furnace is not necessary easily. A highly accurate profile 1 can be produced.

  Further, the cover plate 11 is fixed integrally with the shape body 2 by friction stirring, and the reinforcing material 20 is not exposed to the surface of the shape 1, so the surface of the shape 1 is flat and clean. An excellent appearance can be obtained.

  Furthermore, since the plastic fluidized material 7 fluidized by frictional stirring flows into the gap 6 between the reinforcing material 20 and the concave groove 10 and adheres to the surface of the reinforcing material 20, the reinforcing material 20 is more than conventional. The strength of fixing the shape body 1 can be increased, and the strength of the shape 1 can be increased. In particular, since the reinforcing material 20 is composed of a rod-shaped stranded cable, the surface area with respect to the volume is increased, and the contact area between the reinforcing material 20 and the plastic fluidized material 7 is increased. The fixing strength with the main body 2 can be significantly increased. Further, since the cover plate 11 is integrated with the shape body 2 by friction stirring, the strength of the shape body 2 and the cover plate 11 is higher than that of fixing with an adhesive or the like. Get higher.

  Moreover, since the stranded wire cable is configured by mixing carbon fibers into a resin, it is high in strength and light in weight, and can be bent, so that it can be easily handled during manufacturing.

  Furthermore, since the profile body 2 is composed of an aluminum extruded profile, a complex profile having a plurality of concave grooves 10 can be obtained simply by cutting the extruded profile with an appropriate length. The main body 2 can be easily manufactured. In addition, since the extruded shape made of aluminum has high dimensional accuracy and is light in weight for strength, it is possible to obtain an operational effect that handling during manufacturing processing becomes easy.

[Second Embodiment]
Next, the second best mode for carrying out the present invention will be described in detail with reference to the drawings as appropriate.

  As shown in FIG. 5, in the present embodiment, the size of the shape body 102 of the shape material 101 is smaller than that of the first embodiment, and the number of the insertion portions 105 and the reinforcing materials 20 is reduced by three places. Yes. Of the three, the central insertion portion 105 and the reinforcing member 20 are provided on an extension line of the web 104. In the upper and lower flanges 103, 103, the three insertion portions 105 and the reinforcing member 20 are arranged in contrast to the width direction of the profile body 102.

  Moreover, as shown to (a) and (b) of FIG. 6, in this embodiment, the ditch | groove 110 formed in the profile main body 102 is the wide part 12 (like the ditch | groove 10 of 1st embodiment). 2), and has a U-shaped cross section. Thereby, the width of the groove 110 can be made smaller than the groove 10 of the first embodiment, and the installation pitch of the adjacent grooves 110, 110 can be reduced.

  Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  Hereinafter, a method for manufacturing the shape member 101 having the above-described configuration will be described.

  First, as shown in FIG. 6A, a profile main body 102 having an H-shaped cross section composed of a flange 103 (shown only on one side in FIG. 6) and a web 104 is formed. The flange 103 is integrally formed with a concave groove 110 that opens on the surface side during extrusion. The concave groove 110 is formed to have a constant width from the bottom to the opening, and a reinforcing member 20 (see FIG. 6A) and a cover plate 111 (see FIG. 7A) are formed in the inside. It is supposed to be inserted. The width of the groove 110 is substantially equal to the outermost diameter of the reinforcing member 20 (see FIG. 6B) made of a stranded cable and the width of the cover plate 111. The depth of the groove 110 is The dimension is substantially equal to the dimension obtained by adding the outermost peripheral diameter of the reinforcing member 20 and the thickness of the lid plate 111.

  The concave groove 110 is continuously formed over the entire length of the profile body 102 in the extrusion direction. The concave grooves 110 are formed in a plurality of rows (three rows in the present embodiment) at predetermined intervals in the width direction of the flange 103, and are parallel to each other.

  In the present embodiment, the concave groove 110 is integrally formed when the profile body 102 is extruded, but the present invention is not limited to this. For example, a profile body that does not have a groove is formed by an extruded shape, and the groove may be formed by a known end milling or cutting process.

  Next, as shown in FIG. 6B, the plurality of reinforcing members 20 are sequentially inserted into the respective concave grooves 110. At this time, the outermost peripheral portion of the reinforcing member 20 made of the stranded cable is in line contact with the bottom surface 110a of the concave groove 110 having a semicircular cross section in a spiral shape. Further, the reinforcing member 20 is completely accommodated in the recessed groove 110.

  Thereafter, as shown in FIG. 7A, the plurality of lid plates 111 are sequentially inserted into the opening portions 110 b of the concave grooves 110. The cover plate 111 is made of an aluminum alloy, and has a width equivalent to the distance between the side walls 110 c and 110 c of the concave groove 110, the upper end portion of the reinforcing member 20 inserted into the concave groove 110, and the profile body 102. It has a thickness equivalent to the distance to the surface 102a. Therefore, the side surfaces 111a and 111a on both sides in the width direction of the lid plate 111 are in surface contact with the side walls 110c and 110c of the concave groove 110 or face each other with a minute gap, and the surface 111b of the lid plate 111 It is flush with the surface 102a of the main body 102. Then, at the both ends in the width direction of the lid plate 111, the butted portions 115, 115 of the profile body 102 and the lid plate 111 are respectively positioned.

  Next, as shown in FIG. 7B, friction stirring is sequentially performed along the abutting portions 115 and 115 of the shape body 102 at both ends in the width direction of the lid plate 111. The aluminum alloy material of the profile main body 102 and the cover plate 111 around the butt 115 is heated and fluidized by the frictional heat of friction stirring. Then, the fluidized material (plastic fluid 7) flows into the gap 106 between the reinforcing member 20 and the concave groove 110. Here, since the reinforcing material 20 is composed of a stranded cable, as shown in FIG. 8, the plastic fluid material 7 enters a recess between adjacent wires 20a, 20a, and the plastic fluid material 7 and the reinforcing material. Since the contact area with 20 becomes large and the reinforcing member 20 is locked, the fixing strength becomes high.

  Then, the plastic fluid 7 that has flowed into the gap 106 adheres to the surface of the reinforcing member 20 and is solidified, and the reinforcing member 20 and the profile body 2 are fixed to complete the profile 101.

  According to the method for manufacturing the shape member 101 and the shape member 101, in addition to the same effects as those of the first embodiment, the distance between the adjacent concave grooves 110 and 110 can be reduced. Even if the width of the flange 103 is narrow, many reinforcing members 20 can be provided, and the strength of the shape member 101 can be further increased. In addition, since the dimensions of the shape member 101 can be reduced, the layout can be improved and the degree of freedom in design can be increased.

[Third embodiment]
Next, the third best mode for carrying out the present invention will be described in detail with reference to the drawings as appropriate.

  As shown in FIG. 9, in this embodiment, the size of the profile body 202 of the profile 201 is larger than that of the first embodiment, and the number of the insertion portions 205 and the reinforcing members 20 is five at the upper and lower flanges 103. Increasing each time. Of the five, the central insertion portion 205 and the reinforcing member 20 are provided on the extension line of the web 204, and the five insertion portions 205 and the reinforcing member 20 are formed by the upper and lower flanges 203 and 203, respectively. It is arranged in contrast to the width direction.

  Further, as shown in FIGS. 10A and 10B, in this embodiment, the insertion portion 205 (see FIG. 9) into which the reinforcing member 20 is inserted is a hollow portion formed in the profile body 202. It is constituted by a certain through hole 210. The through hole 210 has a circular cross section and is continuously formed over the entire length of the profile body 202 in the extrusion direction. The through hole 210 has an inner diameter substantially equal to or slightly larger than the outermost diameter of the reinforcing material 20 (see FIG. 10B) made of a stranded cable, and the reinforcing material 20 is inserted therein. Friction heat of friction agitation applied along the surface portion 202 a of the profile body 202 corresponding to the through hole 210 in the gap portion 206 between the inner peripheral surface of the through hole 210 and the surface of the reinforcing member 20. The plastic fluidized material 7 fluidized by the flow is introduced. Specifically, as shown in FIGS. 12A and 12B, the plastic fluidized material 7 flows and fills approximately half of the gap portion 206 on the surface portion 202 a side of the shape body 202.

  Hereinafter, a method for manufacturing the shape member 201 having the above-described configuration will be described.

  First, as shown in FIG. 10A, a profile body 202 having an H-shaped cross section composed of a flange 203 (only one side is shown in FIG. 10) and a web 204 is formed. The flange 203 is integrally formed with through holes (hollow portions) 210 opened at both ends in the extrusion direction during extrusion. The through hole 210 has a circular cross section, and has an inner diameter that is substantially equal to or slightly larger than the outermost diameter of the reinforcing member 20 (see FIG. 10B) made of a stranded cable. The through holes 210 are formed in a plurality of rows (five rows in the present embodiment) at a predetermined interval in the width direction of the flange 203, and are parallel to each other.

  In the present embodiment, the through-hole 210 is integrally formed when the profile body 202 is extruded, but is not limited thereto. For example, a shape body having no through hole may be formed by an extruded shape, and the through hole may be formed by a known drilling process or the like.

  Next, as shown in FIG. 10B, the plurality of reinforcing members 20 are sequentially inserted into the respective concave grooves 110. At this time, the outermost peripheral part of the reinforcing member 20 made of a stranded cable is in line contact with the inner peripheral surface of the through hole 210 having a circular cross section in a spiral shape.

  Thereafter, as shown in FIG. 11, friction occurs along the surface portion 202 a of the profile body 202 corresponding to the through-hole 210 (both end portions in the width direction of the through-hole 210 when the through-hole 210 is projected onto the surface portion 202 a). Stir sequentially. At this time, the surface portion 202a of the profile body 202 and the aluminum alloy material inside thereof are heated and fluidized by the frictional heat of friction stirring. Then, the fluidized material (plastic fluid 7) flows into the gap 206 between the reinforcing material 20 and the through hole 210. Here, since the reinforcing member 20 is composed of a stranded cable, the plastic fluidized material 7 enters the recess between the adjacent wires 20a and 20a as shown in FIGS. 12 (a) and 12 (b). The contact area between the plastic fluidized material 7 and the reinforcing material 20 is increased, and the reinforcing material 20 is locked, so that the fixing strength between the profile body 202 and the reinforcing material 20 is increased.

  Then, the plastic fluid 7 that has flowed into the gap 206 adheres to the surface of the reinforcing material 20 and is solidified, and the reinforcing material 20 and the shape body 202 are fixed to complete the shape 201.

  According to the manufacturing method of the shape member 201 and the shape member 201, in addition to the same effects as those of the first embodiment, a process of providing a cover plate is not necessary as compared with the first embodiment. The effect of being able to achieve a reduction in labor can be obtained.

  On the other hand, when the cover plates 11 and 111 are provided as in the first embodiment and the second embodiment, the abutting portions 15 and 115 with the profile body 2 and 102 appear on the surfaces 2a and 102a. It can be used as a guide line, and it is possible to obtain an effect that it is easy to work.

  The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the reinforcing member 20 is inserted and fixed to the flange 3 (103, 203) of the profile main body 2 (102, 202) having an H-shaped cross section. However, a reinforcing material may be provided on the web. Further, a reinforcing material may be inserted into and fixed to other shapes such as an L-shaped cross-section, a U-shaped cross-section, a flat plate shape, or a pipe shape for reinforcement.

  Furthermore, in the said embodiment, although the reinforcing material 20 is comprised by the rod-shaped member which consists of a strand cable, it is not restricted to this, You may form in plate shape or mesh shape.
