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 roofing material and an outer wall material in a building such as a banquet hall, a gymnasium and an arcade. It relates to the supporting structure.

[0002]

2. Description of the Related Art Conventionally, as a structure for supporting a roof material or an outer wall material in a building having a relatively large space of this type, a frame structure in which a shaped steel is assembled in a lattice shape, or 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 distal end of the auxiliary member 32 are connected by a wire 34 having a turnbuckle 33. A plurality of stringed beams 35 are provided in a space formed by a vertical beam (for example, a column, etc.) and a horizontal beam (for example, a beam of a floor or a roof) of a building in parallel with the vertical beam and with the steel pipe 31 outside. A structure having the above configuration is also employed.

[0003]

Incidentally, the former truss structure is a framed structure in which a shape steel or a steel pipe is joined, so that the weight becomes heavy, and at the same time, a feeling of pressure is felt at the same time as being heavy. Also, in recent years, when a truss structure is adopted for a building in which the outside can be seen from the inside by using a transparent member for the roof material or outer wall material of the building, thick shaped steel and steel pipes hinder the landscape. May be impaired.

On the other hand, the structure using the latter string string 35 is as follows.
The tension of the wire 34 and the compressive force of the steel pipe 31 are imparted by the weight of the string beam 35 and the load such as roof material or outer wall material, and also the load such as external pressure such as rain and wind (hereinafter referred to as positive load). It is a structure that can withstand this, and the weight and pressure feeling are reduced compared to the above truss structure, but when using a roof material with a light weight or when applying to the outer wall, it will be blown up by the wind from the inside of the building When a large outward load (hereinafter referred to as negative load) is applied,
The compression force applied to 31 is canceled out, and the structure does not hold. 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, in the case of a building in which a feeling of pressure is felt at the same time as a feeling of weight, and a transparent member is used for the roofing 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 difficult to see because the 31 is thick and the landscape is damaged.

Further, a roof structure composed of beams and wires has been proposed in Japanese Patent Application Laid-Open No. 61-78934 and Japanese Patent Publication No. 2-22822, etc. The wire is tensioned so as to protrude upward and, like the latter string beam 35, is thick to maintain the function as a compression member that can withstand both positive and negative loads.

The present invention is directed to a beam string composed of the above-mentioned beam and wire, and the beam string can be connected to a vertical beam of a building without increasing the thickness of a steel pipe or the like corresponding to the above-mentioned beam member as much as possible. It is an object of the present invention to provide a structure in a building disposed 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 to attach an auxiliary member to a tubular chord symmetrically with respect to a central portion of the tubular chord. At the same time, a stringed beam formed by connecting both ends of the tubular chord and the tip of the auxiliary member with a wire is placed in a space formed by the vertical and horizontal beams of the building, in parallel with the longitudinal beam and the tubular chord outside. While one or more wires are disposed, a cross-stretching wire is stretched between the auxiliary member and the vertical beam so as to be curved outward in a spatial cross section.

It is stretched so as to be curved outward in the plane.

[0011] One tubular string auxiliary member into the tubular chords
A stringed beam, which is symmetrically mounted around the center of the timber and is connected by wire between both ends of the tubular chord and the tip of the auxiliary member, is inserted into the space formed by the vertical and horizontal beams of the building. In parallel with the above, a plurality of the string members are arranged in parallel with the outer side of the tubular string member, and a tube member parallel to the horizontal beam is arranged between the attachment portions of the auxiliary members of each string string and the tubular string member so as to reach the vertical beam. In addition, a pipe member parallel to the horizontal beam is disposed between the distal ends of the auxiliary members, and a pipe member is disposed between the distal end of the auxiliary member of the string string beam provided at the end and a portion where the pipe member reaches the vertical beam. In addition, a tension wire is stretched between the tip of the auxiliary member and the attachment portion of the auxiliary member with the tubular chord of the adjacent string string so as to be symmetric with respect to the center portion between the vertical beams.

A small arc groove for accommodating the cross tension wire 5 is provided between the intermediate plate 17 and the lower plate 18, and a large arc groove for accommodating the diagonal member 8 formed of a steel pipe is provided in a direction orthogonal to the small arc groove. After the cross tension wire 5 is accommodated in the small arc groove and the diagonal member 8 is accommodated in the large arc groove, the nut 20 is tightened and the oblique material 8 is tightened.
The cross tension wire 5 is attached to the.

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

In the above embodiment, the connection fitting 15
Has been described in which a through hole for a bolt is drilled in advance at a mounting position of the cross tension wire 5 of the diagonal member 8 and the bolt 19 is passed through the hole. However, the present invention is not limited to this configuration. Connection holes without drilling through holes for bolts
Through holes for bolts 19 may be provided at the four corners of each of the 15 plates, and the diagonal members 8 may be attached so as to be sandwiched between the large circular grooves between the intermediate plate 17 and the lower plate 18.

Even in the structure C having the above-described structure, the positive load acting in the space 6 formed by the columns 1 and the upper and lower beams 2 and 3 is mainly carried by the wires 13 of the string beams 4. Further, since all the negative loads are carried by the tension wire 26, the steel pipe 10 of the string string 4 can be made thinner 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 the negative load,
The cross tension wire stretched in the direction orthogonal to the string string or the tension wire stretched in substantially the same direction as the string string bears all, and the tubular string material constituting the string string can be made thin to give a sense of lightness to the space. it can. In addition, since the cross tension wire or the tension wire bears such a negative load, a lightweight covering material is used for the roof material, the wall material, the floor material, etc., and the beam is supported by a thin and lightweight beam string made of a tubular chord material. This can reduce the weight of the entire building.
