However, in the former configurations of FIG. 4 and FIG.
Since the attachment and fixing of the suspension member (B) to the rafter member (D) is performed on the rafter surface (7), the rafter member (D).
Irrespective of the cross-sectional shape of the rafter member (D), there is no possibility of exerting any influence on the lower surface side of the rafter member (D), that is, a hard board or the like interposed on the lower surface side of the rafter member (D). There is no possibility of damaging the base material (E), but the hanging member (8) of the rafter member (D) and the hooking member (9) formed by the hooking locking portion (9). B) The attachment and fixing means, particularly the hooking and locking of the bent locking part (6) by the bent part (9a) of the hooking and locking part (9), the hooking is relatively small. Therefore, in combination with the thickness of the material itself, there is a disadvantage that the required mounting strength or material strength cannot be obtained. In order to improve this point, for example, these cut-and-raised locking pieces (8) and bent portions (9
If the plate thickness with the hooking and locking part (9) including a), that is, the plate thickness of the rafter member (D) itself is increased, or appropriate ribs, diaphragms, etc. are given to the relevant part, A large press or the like has to be employed for processing the mounting portion for the rafter member (D), which causes problems such as poor production efficiency and increased cost.

On the other hand, in the latter configurations shown in FIGS. 6 and 7, the slender member (B) is attached to the narrowed width portion (11b) of the slit-shaped locking hole portion (11) of the rafter member (D). The locking jaws (10b), (10b) of the protruding locking portion (10) are inserted and fixed in place, and the locking hooks are sufficiently secured. ), Even if the plate thickness is relatively thin, it is possible to easily obtain the required mounting strength. However, on the other hand, on the lower side of the rafter surface (7), the locking jaw (10
Since b) and (10b) are projected, the base material (E) interposed on the lower surface side is markedly damaged and rendered unusable, or it is markedly damaged. When there is no such intervention of the base material (E) on the lower surface side of (7), in other words, there is a problem that it can be applied only when there is a space on the lower surface side of the rafter surface (7).

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to attach and fix the suspension member to the rafter surface of the rafter member, and to lower the lower surface of the rafter surface. (EN) It is an object to provide a fixing device for a rafter member and a hanging member of this kind, which can be fixed satisfactorily and effectively with sufficient mounting strength without exerting any influence on the side.

The stop portion (24) is formed as a notch, and the locking tongue piece (26) is extendedly formed on the other end portion side where the retaining locking portion (25) is extended and bent upward.

Further, regarding the rafter member (D) arranged from the ridge side to the eaves side on the main roofing material (C) of the roofing structure to be roofed, the rafter surface (27) is attached to the portion corresponding to the eaves ridge. In position,
The cut-and-raised locking piece (28) is cut and raised corresponding to the one notch-and-locked portion (24) to cut and raise the locking tongue piece (26). ), A bulging locking portion (29) having a locking opening (30) facing toward) is punched out so as to bulge upward.

Here, again, in FIG. 2 (b), reference numeral (E) indicates a hard board or the like interposed between the roofing main member (C) and the rafter surface (27) of the rafter member (D). It is a base member.

In the case of this embodiment, a rafter member (D) arranged in the eaves ridge direction with a base member (E) interposed between it and the main building material (C).
First, as shown by the chain double-dashed line in FIG. 2 (a), the cut-and-raised piece (28) that was cut and raised and was upright was avoided on the rafter surface (27). In this state, the mounting base plate portion (23) of the suspension member (B) is pushed from diagonally above the eaves side to below the ridge side, and its locking tongue (26) is locked at the rafter surface (27). Then, the bulge locking portion (29) is inserted and locked.

Next, the notch engaging portion (24) is cut and raised to receive the engaging piece (28), and the mounting board portion (23) is pressed against the rafter surface (27).

Further, the tip end (28a) of the cut-and-raised locking piece (28) is inserted into the surface of the mounting substrate (23) to be bent, so that it is attached.

The end surface of the locking tongue (26) is made to coincide with at least the lower surface of the substrate, or is made to slightly project from the lower surface.

Then, each suspension member (B) is at a predetermined position on the rafter member (D), and the locking tongue (26) is bulged from the locking opening (30), just as in the case of the previous example. The notch locking part (24) is inserted into the locking part (29), and the notch locking part (24) is locked by being folded into the locking piece (28) so as to be fixed to the rafter member (D). The member (B) is attached and fixed.

Then, the ridge-side engaging portion (47) of the lateral thatched roof plate member (46) from the eave side to the lower side is engaged with the engaging portion (25) of the suspension member (B). Above, this ridge side engagement part (47)
In addition, the eaves side engaging part (21) of the side-roof roofing plate member (48) from the ridge side is further engaged to raise the side-roof roof structure, and the same operation and effect as the previous example can be achieved. Of.

〔The invention's effect〕

As described above in detail, according to the present invention, the suspension member for retaining and locking the lateral thatched roof plate is fixed in the fixing device for fixing the rafter member arranged on the main material of the roof assembly, The hanging member is provided with a notch locking portion on one end side of the mounting base plate portion, and a locking tongue piece is extended and formed on the other end side thereof, and the rafter member is not attached. On the relevant rafter surface, a cut-and-raised locking piece is provided corresponding to the cutout locking portion, and a bulging locking portion having a locking opening for inserting the locking tongue is opened upward. Since it was punched out and formed, it is on the rafter surface of the rafter member, and the locking tongue of the suspension member is inserted into the bulging locking part from the locking opening and locked, and at the same time cut into the notch locking part. The rafter member can be attached by a very simple operation of receiving the raised locking piece and then folding the tip of the locking piece into the mounting board surface. The appropriate rafter surface, can be easily mounted and fixed while being in close contact against press tightly the mounting substrate surface of the retaining clips member.

Also, at the time of this mounting, the locking tongue of the suspension member is inserted from the locking opening into the bulging locking portion that bulges out toward the upper side of the rafter surface and is ejected. Of course, there is no possibility of having any influence on the lower surface side of the rafter surface after the installation is completed, that is, in the mounted state, that is, in other words, there is an interposition between the purlin material and the lower surface of the rafter surface. It is possible to completely eliminate the risk of damaging or causing damage to the underlying member, and to enable stable mounting of the underlying member.

Further, when the suspension member is fixed to the rafter member, the locking tongue of the suspension member is inserted through the locking opening into the bulging locking portion that is punched out to the upper side. Since the locking part covers a sufficient range and the strength of the bulging locking part itself is also sufficiently guaranteed, high mounting strength can be secured even if a relatively thin material is used for the rafter member. At the same time, the rafter member itself has an excellent feature that it can improve the production efficiency of the rafter member to help reduce the cost, and the overall structure is relatively simple and can be easily implemented.
