  However, in the roof structure disclosed in the above-mentioned Patent Document 1, it is not possible to arrange the purlin support bundle at an arbitrary position on the upper member of the truss beam.

  In view of the above circumstances, an object of the present invention is to provide a roof structure in which a purlin support bundle can be arranged at an arbitrary position on an upper member of a truss beam.

  In order to solve the above-described problem, the roof structure of the present invention is located above the upper material portion serving as the unconnected portion of the reinforcing material of the truss beam in which the reinforcing material is disposed between the upper material and the lower material. A bundle main body portion of the purlin receptacle bundle is located, the leg portion of the purlin receptacle bundle has at least a first connection portion and a second connection portion, and at least one of the first connection portion and the second connection portion is the above-mentioned It is fixed to the upper material part used as the connection part of a reinforcing material.

  If it is said structure, the roof load which the bundle main-body part of the said purlin | stuck bundle will receive will be transmitted to the said leg part, and it will become a connection part of the said reinforcing material via at least one of the said 1st connection part and a 2nd connection part. Join the upper material location. Thus, even if the purlin support bundle is arranged at an arbitrary position on the upper member of the truss beam or on an extension line of the upper member, the roof load received by the bundle main body portion of the purlin receiver bundle can be reduced. It becomes possible to transmit to the upper material part which becomes a connection part. In other words, it is not necessary to specially design a truss in which a reinforcing material is arranged in accordance with the position of the purlin bundle.

  Both the first connection part and the second connection part may be fixed to an upper material part serving as a connection part of the reinforcing member in one Fuji-shaped truss beam. According to this, the roof load received by the bundle body portion of the purlin support bundle can be distributed and transmitted to a plurality of reinforcement connecting portions in one Fuji-shaped truss beam.

  The first connection portion is fixed to an upper material portion serving as a connection portion of the reinforcing member in one Fuji-shaped truss beam arranged so as to cross each other, and the above-mentioned in the other Fuji-shaped truss beam or the angle truss beam The said 2nd connection part may be fixed to the upper material location used as the connection site | part of a reinforcing material. According to this, it is possible to distribute and transmit the roof load received by the bundle body portion of the purlin receiving bundle to a plurality of reinforcing material connecting portions present in the truss beams arranged to cross each other. In addition, since the truss beams arranged to cross each other are connected by the leg portions, the truss beams are supported with each other, and the strength of the roof support is improved.

  The first connecting portion is fixed to an upper material portion serving as a connecting portion of the reinforcing member in one Fuji-shaped truss beam, and the second connecting portion is positioned so as to cross the one Fuji-shaped truss beam. It may be fixed to the beam. According to this, the purlin support bundle can be arranged at an arbitrary position on the extension line of the upper member of the Fuji truss beam.

  If it is this invention, there exists an effect that a purlin | bundle support bundle can be arrange | positioned in the arbitrary positions on the upper member of a truss beam, or the arbitrary positions on the extension line of an upper member.
