Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in a building, and more particularly, to an atrium space provided in a building such as a hotel, or a roof material, an outer wall material, etc. in a building such as a banquet hall, a gymnasium and an arcade. It relates to a supporting structure.

[0002]

2. Description of the Related Art Conventionally, as a structure for supporting a roof material and an outer wall material in a building having a relatively large space of this kind, a frame structure in which shaped steels are assembled in a grid shape, a plane truss or a space truss is generally used. In recent years, as shown in FIG. 9, an auxiliary member 32 such as a diagonal member is attached to a steel pipe 31, and both ends of the steel pipe 31 and the tip of the auxiliary member 32 are connected by a wire 34 having a turnbuckle 33. A plurality of stringed beams 35 are arranged in a space formed by a vertical beam (for example, a pillar) of a building and a horizontal beam (for example, a beam of a floor or a roof) parallel to the vertical beam and with the steel pipe 31 outside. A structure having the above structure is also adopted.

[0003]

By the way, the former truss structure is a frame structure in which shaped steels or steel pipes are joined, and the weight becomes heavy, and at the same time, it feels heavy and oppressive. In addition, in recent years, when a truss structure is adopted in a building that uses a transparent material for the roof material or outer wall material of the building so that the outside can be seen from the inside, thick shaped steel and steel pipes obstruct the scenery. May be damaged.

On the other hand, the latter structure using the string beam 35 is
Tension is applied to the wire 34 and compressive force is applied to the steel pipe 31 by the weight of the string beam 35 and the load of the roof material or the outer wall material, and the load of external pressure such as rain and wind (hereinafter referred to as positive load). The structure is more durable than the above-mentioned truss structure, and the feeling of pressure is reduced, but when using a roofing material with a light weight, or when applying it to the outer wall, it is blown up by the wind from the inside of the building. When a large outward load (hereinafter referred to as negative load) acts, the steel pipe
The compressive force applied to 31 is canceled out and the structure no longer holds. With such a structure that can withstand both positive and negative loads, the steel pipe 31 serving as a compression member becomes thick and heavy,
As in the case of the above truss structure, a feeling of pressure is felt at the same time as a feeling of weight, and in the case of a building in which a transparent material is used for the roof material or outer wall material of the building so that the outside can be seen from the inside, the steel pipe There is a problem that the outside is hard to see and the landscape is damaged because 31 is thick.

Further, a roof structure composed of beams and wires has been proposed in Japanese Patent Laid-Open No. 61-78934, Japanese Patent Publication No. 2-22822, and the like. Steel beams to which these roof materials are attached are The wire is configured to be tensioned so as to project upward, and is thick in order to maintain the function as a compression member capable of withstanding both positive and negative loads, as in the latter case of the tension beam 35.

[0006] The present invention is intended for a stringed beam composed of the beam and the wire described above. The stringed beam is used as a longitudinal beam of a building without increasing the thickness of the steel pipe or the like which hits the beam member as much as possible. It is an object to provide a structure in a building arranged in a space formed by a lateral beam.

[0007]

In order to achieve the above object, one of the structures in a building according to the present invention is that a tubular chord member is attached with an auxiliary member in an axially symmetric manner and is connected to both ends of the tubular chord member. A tension string beam formed by connecting a wire to a tip of an auxiliary member is provided in a space formed by a vertical beam and a horizontal beam of a building in parallel with the vertical beam and with a tubular chord member outside 1
One or a plurality of wires are arranged, and a crossing wire is stretched between the auxiliary member and the vertical beam so as to curve outward in a space cross section.

[0008] One is to install a stringer beam in which auxiliary members are axially symmetrically attached to the tubular chord member and the ends of the tubular chord member and the tip end of the auxiliary member are connected by a wire. One or a plurality of tubular chords are arranged parallel to the transverse beam and with the tubular chords on the outside in the space formed by and the cross tension wires are directed outward in the space longitudinal section between the auxiliary member and the transverse beam. It is stretched so as to be curved.

[0009] One of the methods is to attach a supporting member to a tubular chord member symmetrically in the axial direction and connect the ends of the tubular chord member and the tip end of the supporting member with wires. One or a plurality of tubular chords are arranged parallel to the vertical beam and with the tubular chords on the outside in the space formed by, and between the intermediate portion of the auxiliary member of the tension string beam and the attachment portion to the tubular chords and the lateral direction. A tension wire is stretched between the beam and the beam so as to be curved outward in a vertical section in space.

[0010] One is to install a supporting member on a tubular chord member symmetrically in the axial direction and to connect a string chord beam which is formed by connecting both ends of the tubular chord member and a tip of the supporting member with a wire. One or a plurality of tubular chords are arranged in the space formed by and in parallel with the transverse beam and with the tubular chords on the outer side. A tension wire is stretched between the beam and the beam so as to be curved outward in a vertical section in space.

[0011] Another is to install a supporting member on a tubular chord member symmetrically in the axial direction and connect the ends of the tubular chord member with the ends of the supporting member by wires to form a string beam. While arranging a plurality of tubular chords parallel to the longitudinal beam and with the tubular chords on the outside in the space formed by, the pipes parallel to the transverse beam between the attachment parts of the auxiliary members of each tension beam to the tubular chords. Is arranged so as to reach the vertical beam, and a pipe member parallel to the transverse beam is arranged between the tips of the auxiliary members, and the tip of the auxiliary member of the tension string beam arranged at the end and the pipe member reach the vertical beam. Arrange the tubing between the constricted part,
Further, a tension wire is stretched between the ends of the auxiliary members and the mounting portions of the auxiliary members to the tubular chord members of the adjacent tension beams so as to be symmetrical in the direction parallel to the transverse beam.

[0012] One of the methods is to attach a supporting member to a tubular chord member symmetrically in the axial direction and connect the ends of the tubular chord member with the tip end of the supporting member by a wire. While arranging a plurality of tubular chords parallel to the transverse beam and with the tubular chords on the outside in the space formed by, the pipes parallel to the longitudinal beam between the attachment portions of the auxiliary members of each tension beam to the tubular chords. Is arranged so as to reach the horizontal beam, and a pipe member parallel to the vertical beam is arranged between the ends of the auxiliary member, and the end of the auxiliary member of the tension string beam arranged at the end and the pipe member reach the horizontal beam. Arrange the tubing between the constricted part,
Further, a tension wire is stretched between the ends of the auxiliary members and the attachment portion of the auxiliary member to the tubular chord member of the adjacent tension beams so as to be symmetrical in the direction parallel to the longitudinal beam.

[0013]

In the present invention, the tension beam mainly bears the positive load acting in the space formed by the longitudinal beam and the transverse beam,
Further, since all the negative loads are carried by the crossed tension wires or the tension wires, the tubular chord member of the tension chord beam can be made thin, so that the space formed by the longitudinal beam and the transverse beam can be given a feeling of lightness.

The degree of bending of the crossed tension wires or the tension wires is not particularly limited as long as they are stretched in a curved shape so that the designed drag force can be sufficiently exerted. Further, in the case of the crossed tension wire, the number thereof is not particularly limited as long as the tubular chord member is thin and can give a light feeling to the space,
It is desirable that one or two or more be as small as possible. Furthermore, although the attachment to the tension beam is not particularly limited, it is desirable to attach the auxiliary member at a symmetrical position with respect to the axial center.

[0015]

The structure C according to the present invention has a space 6 composed of columns 1, 1 and an upper beam 2 and a lower beam 3.
The eight tension string beams 4 are rotatably attached to the upper beam 2 and the lower beam 3 respectively in parallel with the support columns 1, while the cross tension wires 5 are attached to the auxiliary members 7 of the respective string beams 4 and the support columns 1 at both ends. It is stretched and formed so as to be curved (see FIG. 2) as a whole on the inner side surface of 1.

The above-mentioned tension string beam 4 is structurally the same as the conventional one, and as shown in FIG. 3, an auxiliary member 7 in which two diagonal members 8 and 8 are formed in a V shape by a connecting metal fitting 9. The steel pipe
While installing in the middle of 10 via the connection fitting 11, the steel pipe 10
A connecting metal fitting 12 for attaching to the beams 2 and 3 is attached to both ends of the wire, and a wire 13 is stretched by a turnbuckle 14 between the connecting metal fitting 12 at both ends and the connecting metal fitting 9 at the intersection of the diagonal members 8 and 8. Has become. Then, the diagonal members 8, 8 constituting the auxiliary member 7 are provided at the positions where the crossing wires 5 are attached so as to be curved outward, and the connecting metal fittings 15 shown in FIG.
Is installed.

In the above-mentioned three-divided connecting fitting 15, an upper plate 16, an intermediate plate 17 and a lower plate 18 are laminated in a laminated manner, and through holes for bolts 19 are bored therethrough, and at the same time, the upper plate 16 and the intermediate plate 17 are formed. A small circular arc groove for accommodating the cross tension wire 5 and a large circular arc groove for accommodating the diagonal member 8 formed of a steel pipe between the intermediate plate 17 and the lower plate 18 are formed in the direction orthogonal to the small circular arc groove. The cross wire 10 is housed in the small circular groove and the diagonal member 8 is housed in the large circular groove.
The cross tension wire 5 is attached to the.

Since the structure C according to the present invention has the structure as described above, the positive load acting in the space 6 formed by the columns 1, 1 and the upper and lower beams 2, 3 is mainly caused by the respective string beams 4. Wire 13 bears all of the negative load, and the cross tension wire 5 bears all the negative load, so that the steel pipe 10 of the string beam 4 can be made thin and a light feeling can be given to the space 6.

In the above embodiment, the connection fitting 15
Although the example in which the bolt through hole is previously drilled at the attachment position of the cross tension wire 5 of the diagonal member 8 and the bolt 19 is inserted therethrough has been described, the present invention is not limited to this configuration. Connection fittings without drilling through holes for bolts
Through holes for bolts 19 may be provided at the four corners of each plate of 15, and the diagonal member 8 may be attached so as to be sandwiched by the large arc groove between the intermediate plate 17 and the lower plate 18. Also, the diagonal member 8 is made of steel bar and the connection fitting 15
It is also possible to form a hole for inserting the cross tension wire 5 in advance at the attachment position of the cross tension wire 5 of the diagonal member 8 without using.
Alternatively, the diagonal member 8 may be connected at a mounting position of the cross tension wire 5 of the diagonal member 8 with a steel bar having an insertion hole for the cross tension wire 5 in advance.

Further, in order to mount both ends of the steel pipe 6 to the beams 2 and 3, the connection fitting 12 is used to rotatably mount the pin by inserting the pin into the pin hole 21, but the pin hole 21 is long only on the lower beam 3 side. The holes may be formed to absorb the elongation in the longitudinal direction of the steel pipe 10.

Further, the configurations of the above-mentioned stringed beam 4 and the structure C are not limited to those in the above-mentioned embodiment, and an example of the embodiment is schematically shown in FIG. As described above, the numbers of the auxiliary members 7 and the cross tension wires 5 are appropriately selected in accordance with the scale of the structure C or the purpose.

In the above embodiment, the space 6 having a wall structure, which is formed by the columns 1 and 1 and the upper and lower beams 2 and 3, is taken as an example. However, it is not applicable to the roof or floor structure. Needless to say.

(Embodiment 2) FIG. 6 is a vertical cross-sectional view when a structure of another embodiment of the present invention is applied between columns of a building, and the structure C in this embodiment is the same as the above embodiment. As in Example 1, in the space 6 formed by the columns 1, 1 and the upper beam 2 and the lower beam 3, the eight string beams 4 are rotated in parallel to the column 1 and to the upper beam 2 and the lower beam 3, respectively. While installing as much as possible, replace the crossing tension wire 5 with tension wire 22

Even in the structure C having the above-described structure, the positive load acting in the space 6 formed by the columns 1, 1 and the upper and lower beams 2, 3 is mainly carried by the wire 13 of each string beam 4. Further, since the tension wire 22 bears all the negative load, the steel pipe 10 of the tension string beam 4 can be made thin and the space 6 can be given a light feeling, as in the first embodiment.

In the above embodiment, the tension wire 22 is
Although the mounting positions of the diagonal members 8 and 8 side are the mounting portions to the steel pipe 10, the present invention is not limited to this, and the diagonal members 8 and 8 are not limited to this.
May be in the middle. This is because the tension wire 22 cannot be stretched so as to bend outward as a whole when the diagonal members 8 and 8 are arranged on the intersecting side with respect to the middle, so that the drag force against the negative load cannot be obtained.

(Embodiment 3) FIG. 7 is a cross sectional view of a structure of another embodiment of the present invention applied between columns of a building, and FIG. 8 is a view taken along the line YY of FIG. Therefore, in the structure C in the present embodiment, as in the above-described first and second embodiments, eight stringing beams 4 are provided in the space 6 constituted by the columns 1 and 1, the upper beam 2 and the lower beam 3. , Rotatably attached to the upper beam 2 and the lower beam 3 respectively in parallel to the support column 1, while replacing with the cross tension wire 5 or tension wire 22,
Between the diagonal members 8 and 8 constituting the auxiliary member 7 of the tension beam 4 and the steel pipe 10, the tubular member 23 parallel to the upper and lower beams 2 and 3 is arranged so as to reach the support column 1, and the diagonal member 8 and A pipe member 24 parallel to the upper and lower beams 2 and 3 is disposed between the intersections of 8 and a mounting portion between the intersections of the slant members 8 and 8 of the tension string beams 4 and 4 disposed at the ends and the column 1 of the pipe member 23. The pipe member 25 is arranged between the and, and the diagonal members 8, 4, ---- of the adjacent tension string beams 4, 4, ----
Tension wires 26 are formed between the intersections of the above and the mounting portions of the slant members 8 and 8 to the pipe member 10 so as to be symmetrical in the direction parallel to the upper and lower beams 2 and 3.

Even in the structure C having the above-mentioned structure, the positive load acting in the space 6 formed by the columns 1, 1 and the upper and lower beams 2, 3 is mainly carried by the wire 13 of each string beam 4. Further, since the tension wire 26 bears all of the negative load, the steel pipe 10 of the tension string beam 4 can be made thin and the space 6 can be given a light feeling, as in the first and second embodiments.

[0030]

As described above, according to the structure of the building according to the present invention, the positive load acting in the space formed by the vertical beam and the horizontal beam of the building mainly constitutes the string beam. The tension wire carries, and the negative load is
The crossing tension wire stretched in the direction orthogonal to the string beam or the tension wire stretched in almost the same direction as the tension beam will bear all the burden, and the tubular string material forming the tension beam can be made thin to give a light feeling to the space. it can. In addition, since cross tension wires or tension wires bear such a negative load, use lightweight covering materials for roofing materials, wall materials, flooring materials, etc., and support them with a string beam made of thin and lightweight tubular string materials. This will reduce the weight of the entire building.
