Truss material and manufacturing method of three-dimensional truss diagonal

Technical field

[0001] The present invention relates to a truss material capable of integrally forming a diagonal member of a three-dimensional truss and a method for manufacturing the three-dimensional truss diagonal member.

Background art

[0002] Three-dimensional trusses are used for the skeletons of various structures including the field of architecture and civil engineering. A three-dimensional truss usually has a large number of diagonal members arranged one by one, and both ends of the diagonal member must be joined to the string member by bolts, nuts, welding, etc., which is very laborious to assemble. (For example, see Patent Document 1.) o

[0003] On the other hand, in Patent Document 2, as the truss bars used for the precast concrete plate, a large number of cuts are formed in the longitudinal direction of the strip-shaped plate material, and the plate material is stretched in the width direction to form an expanded metal shape. The sheet is then formed by bending the stretched sheet material into a mountain shape at the center in the width direction. According to this method, it is not necessary to connect a plurality of members by welding or the like, and a single plate member force mountain-shaped truss can be manufactured.

[0004] Further, Patent Document 3 discloses a three-dimensional truss diagonal material (lattice material) formed into a zigzag shape or a spiral shape by applying a crushing force and a bending force to a single pipe-shaped rod. It is described.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the truss material of the present invention (embodiment of the first invention). This truss material is made of a metal plate such as aluminum and is formed into a corrugated plate shape having crests 1 and troughs 2 alternately in the left-right direction. The truss material is orthogonal to the ridgeline 3 of crest 1 and trough 2 The cuts 4a in which the bottom part of the trough 2 is left uncut and the cuts 4b that are perpendicular to the bottom line 5 of the trough part 2 and leave the top part of the peak part 1 are alternately provided in the front-rear direction at intervals.

[0082] When this truss material is stretched in the front-rear direction, each cut 4a, 4b expands and expands, and four diagonal members 6 arranged in a quadrangular pyramid shape as shown in Fig. 2 are taken as one unit. It is possible to integrally form a diagonal member of a three-dimensional truss that is connected in the left-right direction and the front-rear direction. This three-dimensional truss diagonal can be used for a flat three-dimensional truss that supports a roof or a floor, for example.

[0083] As shown in Fig. 3 (a), the truss material shown in Fig. 1 is manufactured by bending a rectangular metal plate 7 into a corrugated plate as shown in Fig. 3 (b). As shown in Fig. 3 (c), the upper and lower side forces can also be produced by making cuts 4a and 4b with a circular saw-shaped cutter 8. Further, the sheet material 7 can be manufactured by making a cut in a corrugated cross-sectional extruded shape that is not bent.

[0084] As another manufacturing method, as shown in Fig. 4 (a), as shown in Fig. 4 (b), first, cuts 4a and 4b are made in a staggered arrangement on the plate material 7, and then as shown in Fig. 4 (b). It is also possible to manufacture by alternately mountain-folding and valley-folding at the middle position of the length of the cut lines 4a, 4b. According to this method, it is possible to make a cut with a small diameter V and a cutter 8, and it is possible to easily manufacture a product having a height dimension H.

[0085] As shown in Fig. 5, the truss material is stretched in the front-rear direction by running a tool 9 having an abacus ball connected in the left-right direction in the front-rear direction above and below the truss material. Can do. At that time, the tool 9 may be powered in the front-rear direction, or the tool 9 may be fixed to power the truss material. It should be noted that the truss material can be stretched simply by pulling it in the front-rear direction without using such a method.

[0086] As shown in Fig. 6 (a), this truss material has height dimensions H and h within one truss material. Can be different. Figs. 6 (b) to (d) show an example in which the extruded profile 10 is used. Fig. 6 (b) shows a large case when the load applied to the truss differs depending on the location. The plate thickness T is increased at the portion where the load F1 is applied, and the plate thickness t is decreased at the portion where the load F2 is small. Fig. 6 (c) shows a drooping wall 11 that hangs downward from the top of the peak 1 to increase the strength. FIG. 6 (d) shows an increase in strength and light weight using a hollow extruded shape member 10 having a hollow portion 11.

[0087] Further, as shown in Fig. 7 (a), this truss material is initially formed with a narrow width and shape! Then, as shown in Fig. 7 (b), the truss material is stretched in the left-right direction. Can be expanded to any width.

[0088] As shown in Figs. 8 (a) and 8 (b), this truss material is pressed along the cut lines 4a and 4b on the plate material 7 before being bent into a corrugated plate shape, and the cut pieces 4a and 4b are pressed. Fin-shaped reinforcing portions 11 and 11 are formed on both sides, and the strength against buckling and bending of each diagonal member 6 can be improved. The reinforcing portion 11 can be provided only on one side of the cuts 4a and 4b.

FIG. 9 (a) is an embodiment in which reinforcing portions 11 are provided on both sides of all the cuts 4a, 4b. In this case, the cross section of each diagonal member 6 is channel-shaped. FIG. 9 (b) shows an embodiment in which the reinforcing portion 11 is provided on one side of all the cut lines 4a and 4b. In this case, the cross section force angle of each diagonal member 6 is formed. Fig. 9 (c) shows an example in which reinforcing portions 11 are provided on both sides of each cut 4b where the top of the crest 1 is left uncut. become

FIG. 10 shows another example of how to provide the reinforcing portion 11. The plate material 7 before being bent into a corrugated plate is formed by continuously forming a plurality of substantially circular cross-sectional reinforcing portions 11 by extrusion molding, and the cuts 4a and 4b are formed between the reinforcing portions 11. In parallel with each other. As shown in FIG. 4 (b), the plate material 7 is bent into a corrugated plate to become a truss material. Even when the reinforcing portion 11 is formed in this manner, each diagonal member 6 is reinforced by the reinforcing portion 11 when the truss material is stretched. The reinforcing portion 11 can also be formed in a fin shape.

[0091] Fig. 11 shows a second embodiment of the truss material of the present invention (embodiment of the second invention;). As shown in Fig. 11 (a), this truss material is formed into a cylindrical extruded profile 12 having crests 1 and troughs 2 alternately in the circumferential direction, as shown in Fig. 11 (b). Perpendicular to ridgeline 3 of mountain 1 and valley 2 The cuts 4a that are left uncut from the bottom and the cuts 4b that are perpendicular to the bottom line 5 of the valley 2 and leave the top of the peak 1 are alternately provided at intervals in the front-rear direction. The cuts 4a and 4b can be formed by cutting using a circular saw, jigsaw, end mill or the like, or by pressing with a press. In addition, in order to obtain the material having the cross-sectional shape shown in FIG. 11 (a), an extruded profile 12 having a star-shaped cross section as shown in FIG. 12 (a) is placed on the outer peripheral side as shown in FIG. 12 (b). Can be produced by spreading. Moreover, it can also form by welding the both ends of the board | plate material bent into the corrugated form.

[0092] When this truss material is stretched in the front-rear direction, each cut 4a, 4b expands and expands, and four diagonal members 6 arranged in a quadrangular pyramid form one unit, which is the circumferential direction and the front-rear direction. It is possible to integrally form an oblique member of a three-dimensional truss with a cylindrical shape (the shape of Fig. 2 curved in the left-right direction).

[0093] Also in the truss material of the second embodiment, as shown in Fig. 8, the force for forming the reinforcing portions 11 on both sides or one side of the cuts 4a, 4b, as shown in Fig. 10, the cuts 4a, 4b The reinforcing part 11 can be continuously formed in parallel with the cut lines 4a and 4b at a position between them, so that the strength of the diagonal member 6 can be improved.

FIG. 13 shows a third embodiment of the truss material of the present invention (third embodiment of the invention;). This truss material uses a hollow extruded aluminum shape 13 with a square cross section, and the cuts 4a and 4b are intermittent along the longitudinal direction at the center of the four peripheral walls 14 and at the four ridges 15. It is provided. The cuts are arranged in a staggered manner by shifting the positions in the longitudinal direction between the cuts 4a provided in the peripheral wall 14 and the cuts 4b provided in the ridge line part 15.

[0095] As shown in Fig. 14, this truss material expands each slit 4a, 4b by spreading each peripheral wall 14 in the width direction so that each ridge line portion 15 spreads to the outer peripheral side, The diagonal member 6 is arranged in an X shape, and a columnar three-dimensional truss diagonal member can be formed integrally.

[0096] FIG. 15 shows a tower 17 using this three-dimensional truss diagonal member. The three-dimensional truss diagonal member formed as described above is vertically installed, and the chord member 16 is formed on the surrounding ridgeline portion. Is installed. Also, when the cuts 4a and 4b are made in the truss material, the length of the cuts 4a and 4b is gradually increased toward the lower side of the tower, so that the length of the diagonal 6 increases toward the lower side. Tatsumi 17 is getting thicker as you go down.

[0097] The truss material of the third embodiment is not limited to a square cross section, but a triangular or hexagonal cross section. It can also be formed in a cylindrical shape. Further, at the position between the cut 4a of the peripheral wall 14 and the cut 4b of the ridge line portion 15, a rod-like or fin-like reinforcing portion is continuously formed in the longitudinal direction by extrusion molding, and the diagonal member 6 can be reinforced. Further, as shown in FIG. 8, the reinforcing portions 11 can be formed on both sides or one side of the cuts 4a and 4b by performing press processing along the cuts 4a and 4b.

FIGS. 16 (a) to (c) show a fourth embodiment (embodiment of the fourth invention) of the truss material of the present invention, and FIGS. 17 (a) to (c) show this embodiment. The manufacturing procedure of truss material is shown. As shown in FIG. 17 (a), this truss material has an upper wall 18, a lower wall 19, and a plurality of vertical walls 20 arranged at equal intervals in the left-right direction. A porous extruded shape 22 formed side by side is cut and formed. As shown in Fig. 17 (b), the vertical forces 18 and 19 are cut by the end mill 23, so that the cuts 4a and 4b are interrupted along the longitudinal direction between the vertical walls 20. Is provided. As shown in FIG. 16 (a), the upper and lower wall cuts 4a and 4b are arranged in a staggered manner with their positions adjacent to each other in the left-right direction shifted in the front-rear direction. As shown in FIG. 17 (c), the vertical wall 20 is intermittently provided with cuts 4c along the front-rear direction by causing the end-mill 23 to carry out a calorie check. The vertical wall cut 4c consists of one of the cuts 4a and 4b provided on the upper and lower walls 18 and 19 shifted in the front-rear direction, and the length and the front-rear direction. Match the position of The lengths of the cuts 4a, 4b, 4c are constant. The upper and lower walls 18, 19 have the same arrangement as that of the vertical wall 20, and are provided with a rod-shaped portion 24 having a circular cross section as a reinforcing portion continuously in the front-rear direction. 19 and vertical wall 20 have cuts 4a, 4b and 4c.

[0099] As shown in Fig. 18 (a), this truss material is pulled and bent in the vertical direction to widen and widen the cut 4c of the vertical wall 20 in the vertical direction. As shown in Fig. 19 (a) and Fig. 19 (b), as shown in Fig. 19 (a) (b) The three-dimensional truss diagonal member as shown in Fig. 1 can be formed integrally. The diagonal member 6 is arranged in the shape of a quadrangular pyramid connected vertically, as shown in Fig. 19 (a) in plan view, and in the form of an oblique lattice, as shown in Fig. 19 (b) in front view and side view. Thus, the diagonal 6 has a double warren shape that intersects in an X-shape. If the string material is fixed to the diagonal lattice points 37a and 37b of the three-dimensional truss diagonal material in the front-rear direction and the left-right direction, it becomes a three-dimensional truss. [0100] The string material may be attached after the truss material is expanded in the vertical direction and the horizontal direction, but is expanded in the vertical direction as shown in Fig. 20 (a) and formed at the upper and lower ends thereof. As shown in FIG. 20 (b), the chord 16 may be fixed to the diagonal lattice points 37a and 37b in the front-rear direction and then expanded in the left-right direction. In this way, the string member 16 can be quickly mounted in a narrow space, and when expanding in the left-right direction, the string member 16 can be pulled and pulled easily. be able to.

[0101] FIG. 21 shows an example of a method of fixing the chord 16 to the diagonal lattice points 37a. As shown in Fig. 21 (a), the top wall 18 is cut and raised at the diagonal lattice point 37a to form a claw 38, and the chord material 16 is a long groove-like material, with a claw on the bottom wall. A slot 39 into which 38 is inserted is formed. Then, as shown in FIG. 21 (b), the claw 38 is inserted into the slot 39, and the chord 16 is placed on the diagonal grid point 37a, and as shown in FIG. Fold inward and squeeze the nail 38 from above with a tool. In this way, the string material 16 can be fixed more easily and reliably than by welding screws.

[0102] The truss material cuts 4a, 4b, 4c may be formed into a narrow slit shape using a circular saw or the like, as shown in FIGS. 22 (a) and 22 (b). Circular through-holes 25 are formed at the longitudinal center and both ends of the cuts 4a, 4b, 4c. The through holes 25 provided at both ends of the cuts 4a, 4b, 4c have the effect of preventing the progress of the cuts 4a, 4b, 4c when the truss material is pulled and bent in the vertical direction or the horizontal direction. The through-hole 25 provided in the central part of 4a, 4b, 4c has an effect of making the cuts 4a, 4b, 4c easily spread.

[0103] In addition, fin-shaped reinforcing portions 11 are continuously formed in the front-rear direction on the upper and lower walls 18, 19 in the same arrangement as the vertical wall 20. As shown in FIG. 8, the reinforcing portions 11 can be provided on both sides of the cuts 4a and 4b in the upper and lower walls.

FIG. 23 shows a fifth embodiment of the truss material of the present invention (fourth preferred embodiment). In the fifth embodiment, the length of the cuts 4a, 4b, 4c is constant regardless of the position in the front-rear direction. , 4b, 4c lengths LI, L2, L3, L4, L5 as soon as possible!

[0105] Fig. 24 (a) shows a state in which this truss material is pulled and bent in the vertical direction, and the cut 4c of the vertical wall 20 is widened and expanded, and Fig. 24 (b) shows this further in the horizontal direction. Pull and bend over and over The cuts 4a and 4b of the lower walls 18 and 19 are shown expanded. By changing the lengths LI, L2, L3, L4, and L5 of the cuts 4a, 4b, and 4c as described above, the diagonal material 6 forces ^ the one that is in the rear edge J becomes longer, as shown in FIG. As shown, it expands in a fan shape when viewed from above. This three-dimensional truss diagonal material can be suitably used for, for example, a bowl-like structure whose height gradually increases or a tower-like structure that becomes thicker as it goes down.

[0106] The length of the cuts 4a, 4b, 4c is arbitrarily determined depending on the position in the front-rear direction, and is not limited to the one that expands into a fan shape as described above. Only the lengths of the rear cuts 4a, 4b, 4c are gradually increased or shortened, or some of the middle cuts 4a, 4b, 4c in the front-rear direction are made longer or shorter than others. It may be.

As shown in Fig. 56 (b), the left and right straight material insertion sections 2L and 2R are spaced at the same distance from the left and right side surfaces with a spacing XI of 1Z2 in the horizontal dimension X of the connecting material 3A. The diameters of the straight material insertion portions 2L and 2R are slightly larger than the diameter of the straight material 1A. The connecting members 3A are arranged in five rows at a position where the entire length of the linear member 1A is divided into four equal parts in a state of being closely aligned in the left-right direction. The distance between the connecting members 3 in the front-rear direction is constant regardless of the position in the front-rear direction. The connecting material 3A is staggered so that the connecting material 3A in the 1st, 3rd and 5th rows and the connecting material 3A in the 2nd and 4th rows are shifted in the left-right direction by a distance XI between the left and right straight material insertion portions. 3, Self-installed, 1, 3, 5 歹 IJ connecting material 3A is left straight and the first and second, third and fourth, fifth and sixth, seventh and eighth straight 1A is connected to each other, and the connecting material 3A in the 2nd and 4th rows is connected to the 2nd and 3rd, 4th and 5th, and 6th and 7th straight materials 1A, respectively. Each linear member 1A is alternately passed through the left and right linear member insertion portions 2L and 2R of the connecting member 3 in the first to fifth rows.

[0142] As shown in Fig. 54 (a), this truss material can be assembled by sequentially inserting the connecting material 3A into the straight material 1A, or straight with respect to the connecting material 3A. It is also possible to assemble by sequentially inserting material 1A. The material of the straight member 1A and the connecting member 3A can be, for example, an aluminum alloy. The straight material 1A may be a solid round bar or a pipe.

First, as shown in Fig. 54 (b), with the connecting material 3A in the first, third, and fifth rows fixed, Pull the connecting material 3A in the fourth row upward and bend each straight material 1A in a zigzag shape. Thereafter, as shown in FIG. 54 (c), the connecting members 3A in the second and fourth rows are pulled in the left-right direction to expand in the left-right direction. As shown in FIG. 57, it is also possible to perform the expansion in the left-right direction first and then expand in the vertical direction. Next, as shown in FIG. 58, the connecting member 3A is clamped with a tool 4A from above and below to fix the connecting member 3A and the linear member 1A. The straight member 1A and the connecting member 3A can be fixed by screwing, riveting, welding, or the like. Next, as shown in FIG. 59, the strip-like string material 6A is passed in the left-right direction on the upper surface 5a of the second and fourth rows of connecting members 3A, and further the strip-like horizontal material 7A is passed in the front-rear direction. Fix the string material 6 A and horizontal material 7A to the connecting material 3A with screws 8A. 1st, 3rd, 5th row of connecting material Pass A and fix to connecting material 3A with screw 8A. The string material 6A and the horizontal material 7A can be fixed to the connecting material 3A by force, riveting, welding or the like. Through the above procedure, the flat truss 10A in which the diagonal members 9A are arranged in a quadrangular pyramid shape can be easily manufactured. The three-dimensional truss 10A formed in this way can be used, for example, to support the roof and floor of a building.

[0144] FIG. 60 shows a seventeenth embodiment of the truss material of the present invention.

The wire 1A is connected in the left-right direction by the first connecting member 12A and the second connecting member 13A.

[0151] The truss material configured as described above includes the first member 13a and the second member of the second connecting member 13A arranged in the second and fourth rows as shown in FIGS. 63 (b) and 64 (b). Pull the member 13b up and down to expand it in the up and down direction, and then pull the first member 13a and the second member 13 b left and right as shown in Figs. 63 (c) and 64 (c). By expanding in the direction, it is possible to easily and integrally form a diagonal material of a double-walled solid truss similar to that of the seventeenth embodiment. This truss material does not require the linear material 1A to be laminated in two stages, and therefore, it is easy to twist.

[0152] In the embodiment described above, the force in which the distance between the front and rear sides of the connecting members 3A, 11A, 12A, and 13A is constant. The connecting members 3A, 11A, 12A, and 13A The front-rear direction interval can be made different. FIG. 66 shows a 20th embodiment of the truss material of the present invention. As shown in Fig. 66 (a), this truss material consists of the first and third rows of connecting material 3 in the front-rear direction L1, and the third and fifth rows of connecting material 3 in the front-rear direction. L2 is different (L2 is longer than L1.) ₀ The connecting material 3A in the second row is placed in the middle of the connecting material 3A in the first and third rows. The 4th IJ connecting material 3A is located between the 3rd IJ and 5th IJ connecting material 3 in between. The other points are the same as those in the sixteenth embodiment.

[0153] As shown in Fig. 66 (b), this truss material pulls the connecting material 3A in the second and fourth rows upward, and then in the second and fourth rows as shown in Fig. 66 (c). When the connecting material 3A is pulled in the left-right direction, it expands into a fan shape when viewed from above. The three-dimensional truss diagonal member formed in this way can be suitably used for, for example, a bowl-like structure whose height gradually increases or a tower-like structure that becomes thicker toward the bottom.

[0154] The manner in which the space in the front-rear direction between the connecting members 3A is made different depending on the location in the front-rear direction is arbitrary, and is not limited to the one that expands into a fan shape as described above, for example, the front side in the front-rear direction Alternatively, the longitudinal distance between the connecting members 3A is gradually increased or shortened only in some sections on the rear side, and the longitudinal distance between the connecting members 3A is increased only in some intermediate sections in the front and rear direction. It may be longer or shorter.

[0155] As described above, the truss material of the present invention includes a plurality of linear members 1A and a plurality of connecting members 3A, 11A, 12A, 13A are connected in the left-right direction, and the connecting material arranged in every other row in the front-rear direction (2A, connecting material 3A, 11A, 13A arranged in the fourth row) is pulled up and down and left and right By simply bending each straight material 1A into a zigzag shape at the same time, the diagonal material 9A is connected to the diagonal material 9A by the connecting materials 3A, 11A, 12A, 13A. Diagonal materials can be easily manufactured integrally. This method also facilitates mechanical automation when manufacturing diagonal members for three-dimensional trusses. Furthermore, the truss material of the present invention is a three-dimensional truss of any size and shape by appropriately adjusting the total length and number of linear members 1A, the front-rear direction and the left-right spacing of the connecting members 3A, 11A, 12A, 13A. Compatible with 10A.

[0156] Further, the truss material of the present invention does not fix the straight member 1 and the connecting members 3A, 11A, 12A, 13A, and the straight member 1A can rotate with respect to the straight member insertion portions 2L, 2R. By doing so, as shown in FIG. 67, an extendable truss 19A that freely expands and contracts in the left-right direction can be provided. Fig. 68 shows an example of the usage state of the telescopic truss 19A. The telescopic truss 19A is arranged vertically, and the connecting members 3A and 3A located at both ends of the straight member 1 are connected to the left and right vertical rails. The shutter is guided to 20A and 20A so as to be movable up and down, and can be expanded and contracted in the vertical direction.

[0157] Fig. 69 shows another example of the connecting member 3A, and Fig. 71 shows a three-dimensional truss 1OA when the connecting member 3A is used in the sixteenth embodiment. This connecting material 3A is provided above the left and right straight material insertion portions 2L, 2R by penetrating a round hole-shaped string material insertion portion 15A in the left-right direction. In a crossing manner, a round hole-shaped horizontal material insertion portion 16A is provided penetrating in the front-rear direction. Three-dimensional truss 10A is made by connecting round bar-like string material 6A and horizontal material 7A into string material insertion part 15A and horizontal material insertion part 16A of connection material 3A and connecting them as shown in Fig. 70. The vertical force of the material 3A is also crushed and crushed by the punch 17A, thereby fixing the string material 6A and the horizontal material 7A to the connecting material 3A. If this connecting material 3A is used, the string material 6A and the horizontal material 7A can be easily attached, and the assembly of the three-dimensional truss 10A becomes easy. As shown in FIG. 72, the present connecting material 3A can be used as it is as the two connecting materials 3A of the seventeenth embodiment. The chord material insertion part 15A and the horizontal material insertion part 16A can be provided in a stepped manner up and down.

[0158] In the sixteenth to twentieth embodiments, the cross-sectional shape of the linear member 1A is arbitrary. For example, as shown in FIGS. 7 3 (a) and (b), the cross-sectional shape of the linear member 1A is a quadrangle. Can also be connected 3A As shown in FIG. 73 (a), the straight material insertion portions 2L and 2R of the straight material 1A may be round holes even when the cross-sectional shape of the straight material 1A is a square, or as shown in FIG. 73 (b). A square hole can be formed in accordance with the cross-sectional shape of the linear member 1A. When the straight material insertion part 2L, 2R is made into a square hole by matching the cross-sectional shape of the straight material 1A, the straight material 1A is prevented from rotating by simply inserting the straight material 1A into the straight material insertion part 2L, 2R. As shown in Fig. 54 (b), after bending the linear material 1A in a zigzag shape, the connecting material 3A does not move, so the work of fixing the linear material 1A and the connecting material 3A is not possible. Can be omitted or simplified. As shown in FIG. 73 (c), a groove 21A is formed in the longitudinal direction on the outer periphery of the linear member 1A having a circular cross section, and the ridge 22A is engaged with the groove 21A in the linear member insertion portions 2L and 2R of the connecting member 3A. And the straight wire 1A can be prevented from rotating by engaging the groove 21A and the protrusion 22A. In addition, as shown in FIG. 73 (d), the linear material 1A is formed so that the ridge 22A provided on the straight material insertion portions 2L and 2R abuts on the outer circumferential surface and corners of the linear material 1A having a non-circular cross section. Can also be prevented.

[0159] In addition, as shown in Fig. 74 (a), the straight member 1A has an insertion portion 18A inserted into the straight member insertion portions 2L and 2R of the connecting member 3A, one turn from the cross section between the connecting members 3A. It is formed in a small cross section, and the connecting material 3A is divided into an upper member 3a and a lower member 3b, and the connecting material 3A has the same size as the straight material insertion portion 18A on the joint surface, and the straight material insertion portion 2L. , 2R, and the straight wire insertion portion 18A can be passed through the straight material insertion portions 2L, 2R. By rubbing in this way, it is possible to prevent the linear member 1A and the connecting member 3A from moving relative to each other in the front-rear direction without fixing the linear member 1A and the connecting member 3A. Furthermore, as shown in FIG. 74 (b), the straight member 1A is formed by dividing it before and after the connecting member 3A, and a protruding insertion portion 18A formed at the end of the straight member 1A is provided on the connecting member 3A. It can also be inserted into the formed hole-shaped linear material insertion portions 2L, 2R. Even in this way, the linear member 1A and the connecting member 3A can be prevented from relatively moving in the front-rear direction, and the straight wire member 1A can have any cross-sectional shape regardless of the shape of the straight member insertion portions 2L and 2R. I can do it. In addition, as shown in FIG. 74 (c), the straight member insertion portions 2L and 2R are formed in a protruding shape on the connecting member 3A, and the insertion portion 18A is formed in a hole shape at the end of the straight member 1A. You can also. In FIG. 74 (a) to (c), the straight member 18A is formed in a non-circular cross section and the straight member 1A is prevented from rotating.

[0160] The truss materials of the sixteenth to twentieth embodiments are various such as building floor slabs, roofs and towers. It can be used for a three-dimensional truss that forms a structure. It can also be used as a truss reinforcement embedded in concrete. Furthermore, it can also be used for a shutter or the like as a stretchable three-dimensional truss. The form of the three-dimensional truss is not limited to a flat plate shape or a column shape.

An arch-shaped three-dimensional truss 10A as shown in Fig. 53 (a) or a dome-shaped three-dimensional truss 10A as shown in Fig. 53 (b) can also be used. The material of the linear member is not limited to an aluminum alloy as long as it is a metal material that can be plastically processed, and may be iron, stainless steel, magnesium alloy, titanium alloy, or the like. The material of the connecting material is not particularly limited, and may be a metal material made of high power resin.
