Definitions
- the present invention relates to a space truss to be used for skeletons of various structures.
- the truss 50 is composed of a rectangular upper lattice 51 composed of chord members 53a and 53b in vertical directions and horizontal directions, respectively; a rectangular lower lattice 52 similarly composed of chord members 54a and 54b in vertical directions and horizontal directions, respectively; and diagonal members 57a and 57b mutually connecting each of intersection points 55 and 56 of the chord members in both of the lattices 51 and 52.
- chord members 53a, 53b, 54a and 54b and diagonal members 57a and 57b must be combined to intersect with one another, and they must be coupled to one another at the intersection points 55 and 56 for fabricating the space truss 50. Consequently, not only the handling of each member such as the management and the transport of them is troublesome, but also the coupling work of the members needs much trouble. Consequently, it has been desired to decrease the number of members as much as possible, or to simplify the coupling work.
- chord members 53a, 53b, 54a and 54b in the vertical directions and the horizontal directions and the diagonal members 57a and 57b are formed by coupling short rod members 58 and 59 divided between each intersection point generally in the known space truss mentioned above, the number of the members is very large, and the handling and the assembling work of them are very troublesome.
- chord members 53a, 53b, 54a and 54b and the diagonal members 57a and 57b are formed by rod members having the lengths equal to the sizes of the respective lattices 51 and 52, the number of the members can be reduced, but the lengths of respective members become longer, which makes the manufacturing, the custody, the transport and the like of the members difficult on the contrary.
- rod members having intermediate lengths covering a plurality of intersection points at some lengths of the rod members, three to four kinds of rod members having different lengths from one another are necessary at the time of coupling a plurality of rod members by combining them in the vertical directions and in the horizontal directions in accordance with the size of a truss, especially in the case where the vertical size and the horizontal size of the truss is different from each other.
- parts to be used such as washers and spacers are also different from one another. Consequently, the management of parts and connection work are troublesome.

- the diagonal members are formed by using bent rod members shaped in a letter V, the bent rod members having coupling portions at both ends and at centers of the rod members, as main members, and by arranging a plurality of bent rod members in a state of intersecting to each other and of intersecting with the chord members of both of the lattices diagonally at positions of the respective intersecting points, and by coupling ends of bent rod members intersecting with a bent rod member to a center of the latter bent rod member at each of the intersection points, and by coupling a straight line rod member with an end of a diagonal member at which the length of the bent rod members is too long in place of the bent rod member, the straight line rod member formed to have a length equal to one side of the letter V of the bent rod members, the straight line rod member including coupling portions at both ends thereof.

That is to say, the chord members in the vertical directions and in the horizontal directions constituting the upper lattice and the lower lattice use the long rod members having the length twice as long as the distance between intersection points as main members, and the long rod members are coupled in order in a specific pattern. Moreover, the above-mentioned diagonal members uses the bent rod members shaped in the letter V as the main members, and the bent rod members are coupled in order in a specific pattern. Consequently, the number and the kinds of the rod members to be used are few, and the handling of them is easy. Moreover, because each rod member can be coupled in order in a fixed pattern, the fabrication work of the truss and the like can be also simplified.
- the coupling portion at the center and the coupling portions at ends of each of the rod members are severally formed by flattening parts of the rod member.
- the coupling portions at the centers and the coupling portions at the ends mutually have the same size, and the coupling portions of each of the rod members of the chord members in the vertical direction and in the horizontal direction and the diagonal members are laid on tops of others directly or with a spacer at each intersection points of both of the lattices, and the chord members and the diagonal members are coupled with one another by being fastened with bolts and nuts with washers arranged on both the sides of the coupling portions.

chord members diagonal members 57a and 57b are formed by rod members having the lengths equal to the sizes of therespective lattices - Though it can be considered to use rod members having intermediate lengths covering a plurality of intersection points, at some lengths of the rod members, three to four kinds of rod members having different lengths from one another are necessary at the time of coupling a plurality of rod members by combining them in the vertical directions and in the horizontal directions in accordance with the size of a truss, especially in the case where the vertical size and the horizontal size of the truss is different from each other. Moreover, in some cases, because the numbers of members to be mutually coupled at each intersection point are different from one another, parts to be used such as washers and spacers are also different from one another. Consequently, the management of parts and connection work are troublesome.
- It is a technical problem of the present invention to decrease the number and the kinds of rod members to be used to make their handling easy, and to simplify the fabrication work of a truss, by forming chord members in the vertical directions and the horizontal directions constituting an upper lattice and a lower lattice of a space truss, and diagonal members coupling both the lattices by forming the chord members and the diagonal members by coupling rod members each having a specific length and a specific shape to be commonly used.
- For solving the problem, a space truss of the present invention is composed of a rectangular upper lattice and a rectangular lower lattice, each composed of chord members in vertical directions and in horizontal directions, the chord members intersecting with each other, and diagonal members coupling intersection points of the chord members in both of the lattices mutually. The chord members in the vertical directions and in the horizontal directions in both of the lattices are formed by using long rod members formed to have a length twice as long as a distance between the intersecting points, the long rod members including coupling portions at both ends and at centers of the rod members, as main members, and by arranging a plurality of long rod members in the vertical directions and the horizontal directions, and by coupling ends of long rod members intersecting with a long rod member to a center of the latter long rod member at each of the intersection points, and by coupling a short rod member with an end of a chord member at which the length of the long rod members is too long in place of the long rod member, the short rod member formed to have a length equal to the distance between the intersection points, the short rod member including coupling portions at both ends thereof. Moreover, the diagonal members are formed by using bent rod members shaped in a letter V, the bent rod members having coupling portions at both ends and at centers of the rod members, as main members, and by arranging a plurality of bent rod members in a state of intersecting to each other and of intersecting with the chord members of both of the lattices diagonally at positions of the respective intersecting points, and by coupling ends of bent rod members intersecting with a bent rod member to a center of the latter bent rod member at each of the intersection points, and by coupling a straight line rod member with an end of a diagonal member at which the length of the bent rod members is too long in place of the bent rod member, the straight line rod member formed to have a length equal to one side of the letter V of the bent rod members, the straight line rod member including coupling portions at both ends thereof.
- The space truss of the present invention including the above-mentioned configuration is configured as follows. That is to say, the chord members in the vertical directions and in the horizontal directions constituting the upper lattice and the lower lattice use the long rod members having the length twice as long as the distance between intersection points as main members, and the long rod members are coupled in order in a specific pattern. Moreover, the above-mentioned diagonal members uses the bent rod members shaped in the letter V as the main members, and the bent rod members are coupled in order in a specific pattern. Consequently, the number and the kinds of the rod members to be used are few, and the handling of them is easy. Moreover, because each rod member can be coupled in order in a fixed pattern, the fabrication work of the truss and the like can be also simplified.
- In the present invention, the coupling portion at the center and the coupling portions at ends of each of the rod members are severally formed by flattening parts of the rod member.
- According to a concrete configuration embodiment of the present invention, the coupling portions at the centers and the coupling portions at the ends mutually have the same size, and the coupling portions of each of the rod members of the chord members in the vertical direction and in the horizontal direction and the diagonal members are laid on tops of others directly or with a spacer at each intersection points of both of the lattices, and the chord members and the diagonal members are coupled with one another by being fastened with bolts and nuts with washers arranged on both the sides of the coupling portions.
- According to another concrete configuration embodiment, sizes of the coupling portions of the ends of each of the rod members are a half of a size of the coupling portion at the center of the rod member, and a reinforcing member is integrally provided on one side of each of the coupling portions, the reinforcing member also functioning as a spacer, and coupling portions of ends of two rod members of the chord members in the vertical directions and in the horizontal directions and the diagonal members, the two rod members intersecting with a rod member, are directly laid on the top of the coupling portion at a center of the latter rod member in a state of being placed opposite to each other at each of the intersection points of both of the lattices, and each of the coupling members are mutually coupled by being fastened by a plurality of bolts and nuts with washers disposed on both sides of the coupling members.
- In the present invention, at each of inside intersection points except intersection points positioned at periphery portions of both of the lattices among each of the intersection points at which the chord members and the diagonal members are coupled to one another, a coupling numbers of the rod members of the chord members and the diagonal members are severally three, and the chord members and the diagonal members are mutually coupled at each of the intersection points in the inside by the same coupling structure.
- Thereby, because the above-mentioned chord members and the diagonal members can be coupled at each intersection point by using the same parts and by the same method, the fabrication of the truss becomes simpler.

- In the following, embodiments of the present invention are described in detail on the basis of the drawings. Figs. 1-3 schematically show an embodiment of a space truss according to the present invention. The
space truss 1 has a basic form common to that of theconventional truss 50 shown in Figs. 12 and 13. Thespace truss 1 is composed of a rectangularupper lattice 2 composed ofchord members 2a and 2b in vertical directions and in horizontal directions, which intersect with each other; a rectangularlower lattice 3 similarly composed of chord members 3a and 3b in vertical directions and in horizontal directions; anddiagonal members intersection points 5 of thechord members 2a and 2b in theupper lattice 2 andintersection points 6 of the chord members 3a and 3b in thelower lattice 3. However, thespace truss 1 differs from theconventional truss 50 mentioned above in the configurations with regard to thechord members 2a, 2b, 3a and 3b and thediagonal members - Incidentally, for simplifying the drawings, in Fig. 1, the
chord members 2a, 2b, 3a and 3b in theupper lattice 2 and thelower lattice 3 in the vertical directions and in the horizontal directions are exhibited by means of solid lines having different thicknesses from each other, and thediagonal lines upper lattice 2 and thelower lattice 3 are emphasized. In Fig. 2, thediagonal lines upper lattice 2 and thelower lattice 3 are exhibited by chain lines and dotted lines, respectively. Thereby, thediagonal lines - The
chord lines 2a, 2b, 3a and 3b in the vertical directions and in the horizontal directions in theupper lattice 2 and in thelower lattice 3 mentioned above are each formed of along rod member 8, which has a length twice as long as a distance L betweenintersection points 5, as a main material, as shown in Fig. 4(A). Ashort rod member 9 having a length equal to the distance L between the intersection points is used at an ends of parts of the chord members, as shown in Fig. 4(B). Any of thelong rod member 8 and theshort rod member 9 is composed of a pipe member made of a metal having a cross section of a circle or a square shape. In case of thelong rod member 8, thelong rod member 8 includes flattenedrectangular coupling portions short rod member 9, theshort rod member 9 includes flattenedrectangular coupling portions 9a at both the ends thereof. Each of thecoupling portions reference numeral 12 in the drawings denotes a bolt hole formed in each of thecoupling members upper lattice 2 and thelower lattice 3 mentioned above are configured by means of theselong rod members 8 and theshort rod members 9 as follows. Incidentally, both of theselattices lattice 2. - That is to say, as shown in Fig. 5 in a magnified manner, the
chord members 2a and 2b in the vertical directions and in the horizontal directions in theupper lattice 2 are formed by arranging the above-mentionedlong rod members 8 in the vertical directions and in the horizontal directions to couple them in order. At that time, the disposition positions of thelong rod members 8 in adjacent chord members in either group of thechord members 2a or 2b are mutually shifted by the half lengths of thelong rod members 8, i.e. by the distance L between intersection points, in axial line directions, and thereby thecoupling portions 8a of the ends of thelong rod members 8 intersecting with along rod member 8 are severally coupled to thecentral coupling portion 8b of thelong rod member 8. The coupling pattern is repeated. Then, as shown in Fig. 1, when the length of the above-mentionedlong rod member 8 is too long in case of coupling thelong rod member 8 to the end of a chord member, theshort rod member 9 is coupled to the end of the chord member in place of thelong rod member 8. By connecting thelong rod members 8 and theshort rod members 9 in such a pattern in order, the rectangularupper lattice 2 is formed. Also thelower lattice 3 is similarly formed. - Moreover, the above-mentioned
diagonal members bent rod members 10 bent in the shape of a letter V as shown in Fig. 6(A) as main members. A straightline rod member 11 formed to have the same length as that of one side of the letter V of the above-mentionedbent rod member 10, as shown in Fig. 6(B), is used to the ends of parts of the diagonal members. Both of thebent rod member 10 and the straightline rod member 11, mentioned above, are made of a metal pipe member. In case of thebent rod member 10, therod member 10 includes flattedrectangular coupling portions rod member 10. In case of the straightline rod member 11, therod member 11 includes flattedrectangular coupling portions 11a at both the ends thereof. Each of thesecoupling portions coupling portions long rod member 8 and theshort rod member 9 mentioned above. - Then, as it is clear from Figs. 2 and 7, a plurality of
bent rod members 10 is arranged in order to be intersected with one another, and in order to be obliquely intersected at therespective intersection points chord members 2a, 2b, 3a and 3b of both thelattices coupling portions 10a at the ends of thebent rod members 10 intersecting with abent rod member 10 are severally coupled to thecoupling portion 8b at the center of thebent rod member 10. Moreover, when the length of the above-mentionedbent rod member 10 is too long in case of coupling thebent rod member 10 to the ends of the diagonal members, the above-mentioned straightline rod number 11 is coupled with the ends of thediagonal members bent rod member 10. Areference numeral 13 in Fig. 6 denotes a bolt hole formed in each of thecoupling portions - The above-mentioned
bent rod members 10 are severally arranged in the state of an inverted letter V with thecoupling portions 10b at the centers being upward, and thecoupling portions 10b at the centers are coupled to the intersection points 5 of thechord members 2a and 2b of theupper lattice 2, and further thecoupling portions 10a on both ends are coupled to the intersection points 6 of the chord members 3a and 3b of thelower lattice 3 in thediagonal members 4a sloping upward when going from left to right in the drawings. On the other hand, in thediagonal members 4b sloping downward when going from left to right, the above-mentionedbent rod members 10 are severally arranged in the state of a letter V with thecoupling portions 10b at the centers being downward, and thecoupling portions 10b at the centers are coupled to the intersection points 6 of the chord members 3a and 3b of thelower lattice 3, and further thecoupling portions 10a on both ends are coupled to the intersection points 5 of thechord members 2a and 2b of theupper lattice 2. - Each of the above-mentioned
rod members chord members 2a, 2b, 3a and 3b and each of thediagonal members intersection points chord members 2a, 2b, 3a and 3b. Figs. 8 and 9 typically show the coupling structure of thechord members 2a and 2b in the vertical direction and in the horizontal direction in theupper lattice 2 with thediagonal members intersection point 5 of thechord members 2a and 2b. Theintersection point 5 is one of the intersection points 5 except theintersection points 5a positioned on the periphery portion of the upper lattice 2 (see Fig. 1) to be positioned in the inside of theintersection points 5a. At each of the intersection points 5 positioned in the inside of the lattice, thechord members 2a and 2b in the vertical direction and in the horizontal direction and thediagonal members coupling portion 8b at the center of thelong rod member 8 constituting the chord member 2a in one direction and thecoupling portions 8a of the ends of thechord members 2b intersecting with the above-mentionedlong rod member 8 are mutually laid on the top of another, and thecoupling portion 10b at the center of thebent rod member 10 constituting thediagonal member 4a in one direction and thecoupling portions 10a at the ends of thebent rod members 10 constituting thediagonal members 4b intersecting with the above-mentioneddiagonal member 4a are mutually laid on the top of another withspacers 14a and 14b put between them at the laying portion. The laying portion is fixed with abolt 16 and anut 17 with puttingwashers 15 disposed on both ends of the laying portion between. - Incidentally, in Fig. 9, a state in which the cross section taken along an A-A line in Fig. 8 with regard to the intersection portion of the
chord members 2a and 2b in the vertical direction and in the horizontal direction is shown, and a state in which the cross section taken along a B-B line in Fig. 8 with regard to the intersection portion of thediagonal members - As described above, at each of the above-mentioned
intersection portions 5 positions in the inside of theupper lattice 2, the number of the mutually coupledrod members chord members 2a and 2b in the vertical direction and in the horizontal direction and the number of the mutually coupledrod members diagonal members common spacers 14a and 14b, thewasher 15, thebolt 16, thenut 17 and the like, and thereby the management of parts, coupling work and the like are very simple. The advantage can be achieved by coupling each of the above-mentionedrod members chord members 2a and 2b in the vertical directions and in the horizontal directions and thediagonal members lower lattice 3. - On the other hand, at the intersection points 5a and 6a positioned on the periphery portions of the
lattices rod members intersection points same spacers 14a and 14b, thewashers 15, thebolts 16, the nuts 17 and the like. - Incidentally, the coupling structure of the intersection points 5 and 6 is not limited to the above-mentioned example, but the other coupling structures can be used. For example, each of the
coupling portions rod members - Figs. 10 and 11 typically show the second embodiment of the coupling structure of the
chord members 2a and 2b and therod members intersection point 5 positioned in the inside of theupper lattice 2 similarly in the case shown in Figs. 8 and 9. In the second embodiment, thecoupling portions respective rod members coupling portions members coupling portions members members bolt holes 12 are severally formed at corresponding positions in thecoupling portions long rod member 8a and thebent rod member 10. Two bolt holes 12 are formed in each of thecoupling portions 8a at the ends of thelong rod member 8. On the other hand, in thecoupling portions 10a at the ends of thebent rod member 10, onebolt hole 12 is formed at the center of each of thecoupling portions 10a, andhalf holes 12a are severally formed on both the ends of thecoupling portions 10a. Then, abolt hole 12 is formed by twohalf holes 12a standing opposite each other of both thecoupling portions 10a when thecoupling portions 10a of twobent rod members 10a are placed opposite to each other. - Then, the
coupling portions 8a at the ends of the twolong rod members 8 forming thechord members 2b intersecting with a chord member 2a in one direction are directly laid on the top of thecoupling portion 8b at the center of thelong rod member 8 constituting the chord member 2a in the one direction by abutting the mutual back faces, where the reinforcingmembers 20a and 20b are not formed, against each other in the state of placing the edges of thecoupling portions 8a opposite to each other. Moreover, thecoupling portions 10a at the ends of the twobent rod members 10 forming thediagonal members 4b intersecting with adiagonal member 4a in one direction are directly laid on the top of thecoupling portion 10b at the center of thebent rod member 10 constituting thediagonal member 4a in the one direction by abutting the mutual back faces, where the reinforcingmembers 21a and 21b are not formed, against each other in the state of placing the edges of thecoupling portions 10a opposite to each other. Furthermore, each coupling portion of thechord members 2a and 2b and thediagonal members members 20a and 21a against each other, and each of the coupling portions is fastened with fourbolts 16 and fournuts 17 with thewashers 15 disposed on both the sides of the coupling portions between. Thereby the coupling portions are mutually coupled. - Incidentally, in the second embodiment, although it is not specially shown, the
coupling portions short rod member 9 and the straightline rod member 11 are also formed in the same sizes as those of thecoupling portions long rod member 8 and thebent rod member 10, and the reinforcingmembers 20a and 21a are integrally formed on respective coupling portions. Moreover, in the case where no coupling portions to be placed opposite to each other exist because the number of the rod members to be coupled is few at theintersecting points 5a positioned on the periphery portion of the above-mentionedlattice 2, a spacer having the thickness same as that of the coupling portion is independently set at that portion to be coupled by a method similar to that of Fig. 9. - The coupling structures of the intersection points in the above-mentioned second embodiment are quite the same as those of the
lower lattice 3. - Thus the
space truss 1 configures thechord members 2a, 2b, 3a and 3b in the vertical directions and in the horizontal directions, which chord members constitute theupper lattice 2 and thelower lattice 3, by coupling thelong rod members 8 having the length twice as long as the distance L between intersection points as main members in order in a specific pattern, and configures thediagonal members lattices bent rod members 10 shaped in the letter V as main members in order in a specific pattern. Consequently, the number of the rod members to be used is decreased to almost a half of the number of the rod members of the conventional truss formed by using short rod members divided to each intersection interval, and then the handling of the rod members is easy. Moreover, because each rod member can be connected in order in a fixed pattern, the assembling work and the like of thetruss 1 are also simplified. Because the coupling number of the rod members and the coupling structures at each intersection points 5 and 6 are made to be common and the parts such as the reinforcing members, the washers, the bolts and the nuts are also made to be common as well, the assembling work and the like of the truss become further easier, and the management of the parts to be used also is easy. - The above-mentioned
truss 1 can be formed in a plane shape by forming thechord members 2a, 2b, 3a and 3b in the vertical directions and in the horizontal directions severally by using the straight linelong rod members 8 and theshort rod members 9, and thetruss 1 can be formed in an arch shape by forming either thechord members 2a, 3a or 2b, 3b in the vertical directions or in the horizontal directions by using thelong rod members 8a and theshort rod members 9, both bent in arches. - As described above, according to the space truss of the present invention, chord members in the vertical directions and in the horizontal directions constituting the upper lattice and the lower lattice, and the diagonal members coupling these chord members are formed by coupling rod members which have specific lengths and specific shapes to be used in common. Thereby, the present invention is fitted to decrease the number and the kinds of the members to be used for making it easy to handle the members, and to simplify the fabricating work and the like of the truss.
