Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel mounting structure for suspending a plurality of roof panels to which a purlin is fixed in advance on a roof frame and assembling the roof panels into a flat roof on the roof frame. Is.

[0002]

2. Description of the Related Art In view of the shortage of workers and the soaring construction costs in recent years, roof panels have been processed to tiles in advance in factories other than construction sites, and roof panels tend to be united as much as possible. Conventionally, the roof panel in this case is made by fixing a purlin made of steel section with a U-shaped cross section to the lower surface of the roofing board whose upper surface is tiled. By fixing it so as to be orthogonal to the upper chord member of the truss in the flow direction of the roof, it is joined so as to be flush with other roof panels (Japanese Patent Laid-Open No. 5-179763 and Japanese Patent Laid-Open No. 4-64433). reference).

[0003]

However, in the past, since the purlin of the roof panel was fixed to the upper chord member of the truss, which is a component member of the shed assembly, with bolts at a large number of points, a lot of man-hours were required for the bolt fastening work. In addition, the bolts must be tightened inside the hut after the roof panel has been hung up.Therefore, the worker who was hanging up on the roof must either turn to the hut or move the worker in advance to the hut. I need to keep it inside,
From this point as well, the construction work of the roof took a lot of work.

Further, conventionally, since the purlin is simply fixed to the existing truss upper chord member by bolts, when the truss upper chord member has a warp or an assembly error, the mounting position of the roof panel is also displaced accordingly. Therefore, the roof panels may not be joined flush with each other. In view of such an actual situation, the present invention allows the roof panel to be mounted on the roof assembly without bolting work in the attic, and even if the truss upper chord member has a warp or an assembly error, the roof panel can be placed at an appropriate position. It is a primary object to provide a roof panel mounting structure to be mounted.

A second object of the present invention is to reduce the labor required for the roof panel so that the roof panel can be joined at the same time as mounting on the truss upper chord member.

[0006]

[Means for Solving the Problems] In order to achieve the above object,
The present invention has taken the following technical means. That is, in order to achieve the first object, the present invention is provided with a purlin fixed to the lower surface of the base plate and a truss upper chord member in the roof flow direction which constitutes a shed structure, and the purlin is orthogonal to the truss upper chord member. In the mounting structure of the roof panel fixed as described above, a locking member for locking the lower section of the purlin and restricting its downward movement in the roof flow direction is provided on the truss upper chord member. The level adjusting means for adjusting the height from the upper chord member of the truss of the above is provided.

More specifically, the purlin has a lateral flange portion in the lower portion of its cross section, and the latching member is provided with a lateral plate portion at the lower end of the vertical plate portion, and the lateral plate portion has a roof flow direction. The vertical plate is fixed to the upper surface of the upper chord member of the truss on the upstream side in the roof flow direction by mounting bolts so as to face upward. In this case, the flange portion is hooked between the lateral plate portion and the protruding portion of the mounting bolt, and the level adjusting means is configured by inserting the mounting bolt into a vertically long slot formed in the mounting wall.

As another concrete means, the purlin has a lateral flange portion at the lower portion of its cross section, and the latching member is

In this case, the flange portion is hooked between the support plate and the upper double nut, and the level adjusting means is composed of the upper and lower double nuts.

Further, in order to achieve the second object, in addition to the above structure, a pin is provided on one end face of the roof panel, and a connecting hole corresponding to the pin is provided on the other end face of the roof panel.

[0010]

The hook member 17 hooks the lower part of the cross section of the purlin 11 and restricts its downward movement in the roof flow direction. Therefore, the roof panel 9 is placed on the roof frame 4 without bolting work at the back of the roof. It is attached. Further, since the height of the hook member 17 from the truss upper chord member 6 can be adjusted by the level adjusting means 26, the roof panel 9 can be attached at an appropriate position even if the truss upper chord member 6 has a warp or an assembly error.

On the other hand, when the roof panel 9 is attached to the truss upper chord member 6, the pin 31 of the existing downstream roof panel 9 is used.
