A bolt hole having a diameter corresponding to the screw diameter of a fitting mounting bolt must be opened at a plurality of positions set corresponding to the weight to be carried. For this reason, there is a risk of rainwater leaking to the indoor side through each of these bolt holes. Further, there is a problem in that the tightening work using the mounting bolts and nuts at a plurality of places is extremely troublesome and troublesome.

In addition, the mounting holes of the latter mounting face plate (11) are
The work of engaging the mounting piece of 1), folding it back and fixing it also had the same inconvenience as the former case.

However, according to this configuration, the contact area between the mounting face plate of the tile block and the cut-and-raised protrusions is small, and the curved shape of the face plate is complicated, so it is difficult to mount the face plate on the mounting member exactly. There was a problem.

Further, in the above invention, since a mounting member such as an elastic fixing piece has not been used, when engaging and fixing the tile block to the face plate, stress concentration is likely to occur at the engaging tip portion of the tile block, There is also a problem that the engaging tip portion is easily damaged.

Therefore, an object of the present invention is, in view of such problems of the related art, to make it possible to attach the mounting face plate to the base material without opening any mounting hole or the like in the mounting face plate. It is an object of the present invention to provide a fixed support device for a mounting face plate for tensioning a tile block, in which a base material and a mounting face plate are fitted tightly and fixed support can be obtained between them.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a fixed support device for a tile block tensioning mounting face plate according to the present invention is made of a metal elongated material, and has a flange portion, and a flange portion. Provided on the front side is a base material that is inclined upward and is inclined upward and has protruding engagement pieces, and the front side protrudes in an inverted dovetail groove shape and the back surface side is recessed in a dovetail groove shape. Supports the ridges and the back of the tile block, and
A receiving projection having a groove depth shallower than the engaging projection is provided with a mounting face plate formed over a plurality of vertical steps, and the mounting face plate is fixedly supported on the base on the side of the body, A tension block tension structure in which individual tile blocks are attached and stretched by elastic fixing pieces to the engaging protrusions from the front surface side, wherein the upper surface of the engaging pieces and the engaging protrusions. The upper inner surface of the dovetail-shaped recess that forms the back side of the strip is used as a contact surface of a predetermined length to engage the hook, and at the lower part of the engaging recess groove of the tile block, the elastic fixing piece is engaged. The landing piece is on the lower side engaging surface of the engaging ridge, the pressing piece with the tip of the pressing piece formed downward is on the pressing surface of the tile block, and one end of the substrate is on the upper side of the facing part of the receiving ridge. The engaging ridges and the receiving ridges are sandwiched between the engaging surfaces so that they come into contact with the engaging surfaces. It is characterized in that so as to tile block fixing support.

[Action]

Therefore, according to the present invention, the upper surface of the engaging piece cut and raised at arbitrary plural points on the surface side of the base material and the upper inner surface of the dovetail-shaped concave portion forming the rear surface side of the engaging projection of the mounting face plate. And contact surfaces of a predetermined length for hooking engagement, and at the bottom of the engaging groove of the tile block, an elastic fixing piece is attached, and the engaging piece (53) is attached to the lower side of the engaging ridge (12).

It is possible to fix and support the on the base material exactly and stably. That is, since the upper surface (64a) of the cut-and-raised engagement piece (64) and the upper inner surface (13b) of the dovetail-shaped recess (20) are in surface contact with each other, stress concentration can be avoided.
The engaging piece (53) of the elastic fixing piece (51) abuts the lower engaging surface (14a) of the engaging projection (12), and the pressing piece (55) of the elastic fixing piece (51) becomes the tile block. The pressing surface of (31) is elastically held, and the base plate portion (52) of the elastic fixing piece (51) receives the receiving ridge (1
Since it abuts on the engaging surface (17a) at the upper part of the facing portion of 6), not only a lightweight tile block but also a heavy tile block can be locked.

Moreover, since there is no need to open the mounting hole or the like in the mounting face plate, the strength of the mounting face plate itself is not impaired, and the fixing and supporting work thereof is extremely easy, and the roof is not opened from the opened portion. It is possible to completely eliminate the risk of water leakage such as rainwater to the inside.

Furthermore, in addition to the use of the elastic fixing piece, even if a load is applied to the mounting face plate by tensioning a relatively heavy tile block, the elastic fixing piece functions as a tile block without difficulty. It is possible to prevent the tile block from being damaged at a position where it comes into contact with the mounting face plate, so that the base material is securely fixed and supported.
