Description

The present invention relates to an eaves rod suspension fitting that supports an eaves rod disposed at the eaves edge of a folded plate roof.

  FIG. 4 shows a construction example of the eaves cage 2 using the conventional eaves rod suspension fitting 3. FIG. 4A is a conventional example in which the eaves 2 is suspended and supported by the eaves hanging metal fitting 3 in the folded plate roof 1 using the folded plate 1a often used in factories and the like. The roof slope of the folded plate roof 1 (= tan θ1, where θ1 is the roof inclination angle) is generally about 3/100. In FIG. 4, A is a C-type steel for receiving a roof, B is an outer wall panel, and C is a C-type steel that joins the outer wall panel B. The same reference numerals are given to corresponding members in the drawings.

On the other hand, FIG. 4B and FIG. 4C show a conventional example in which the eaves ridge 2 is supported by the eave ridge suspension fitting 3 or the eave ridge receiving fitting 5 on the slate roof 4 in which the corrugated slate 4a is used. The roof slope of the slate roof 4 (= tan θ2, where θ2 is the roof inclination angle) is generally about 3/10. This type of metal fitting supports the eaves 2 in a cantilevered state, so the eaves are inclined due to the weight of the eaves and rain water, so it is not suitable for large eaves.

When repairing the slate roof 4 as shown in FIG. 4B or FIG. 4C used for a long period of time, the slate roof 4 is not removed, but the folded plate is formed on the upper surface of the corrugated slate 4a forming the slate roof 4. There is a repair method that superimposes la. FIG. 3 shows a slate roof 4 refurbished by such a renovation method. According to this renovation method, when the slate roof 4 is removed during the refurbishment, it is possible to avoid being exposed to rain and to reduce the amount of waste.

When installing the eaves ridge 2 on the refurbished roof 1, the existing eave ridge suspension fitting 3 shown in FIG. 4A cannot stably suspend and support the eave ridge 2 with respect to the folded plate 1a. This is because the roof slope is as steep as about 3/10.

Patent Document 1 discloses an eaves-hanging metal fitting that suspends and supports an eaves wall in a general folded-plate roof having a roof gradient of about 3/100. When the eaves hanging bracket is used as it is, the bending angle of the eaves-end fixture A fixed to the front end of the folded plate is a folded plate having a roof gradient of about 3/10 as in the modified roof shown in FIG. The eaves on the roof cannot be supported in a proper posture. Furthermore, even if the bending angle of the eaves-end fixture A is adjusted, the eave bar is suspended and supported in a cantilever state, which is disadvantageous in holding a large eave bar.

In patent document 2, it respond | corresponds to a roof gradient through the washer formed in the inclined surface. This is disadvantageous in that the number of parts when attaching the metal fittings to the folded plate roof increases, and the work takes time. In addition, in patent document 2, although the screw shaft rod (equivalent to the code | symbol 3a of FIG. 4A) is forcedly bent and the example corresponding to a roof gradient is also disclosed, workability | operativity is bad.

The installation of the eaves cage 2 using the eaves rod suspension fitting 100 will be described with reference to FIG.
First, the fixing portion 8 of the folded plate 1a is arranged so that the front end portion of the folded plate 1a in the folded plate roof 1 is positioned between the first side portion 8a and the second side portion 8b. Engage from the front side of the front end.

Next, the tapping screw 13 is inserted into the first through hole f1, and then a pressing force and a rotational force are applied to the tapping screw 13 by an electric screwdriver or the like. As a result, the tapping screw 13 forms a hole in the front end portion of the folded plate 1a, then forms a female screw on the inner peripheral surface of the screw forming lower hole f2 of the second side portion 8b, and is screwed into this female screw. Thus, the first side 8a, the front end of the folded plate 1a, and the second side 8b are joined together. As a result, the eaves hanging metal fitting 100 is fixed to the tip of the folded plate 1a.

If the tapping screw 13 fails to thread the screw forming lower hole f2, etc., a through-hole penetrating the first side 8a and the folded plate 1a is drilled at the position of the second through hole f3. Then, the bolt 14 is fastened with a nut from the lower side of the folded plate 1a. As a result, the eaves hanging metal fitting 100 is fixed to the tip of the folded plate 1a.

The above process is repeated to attach the required number of eaves hooks 100 to the folded plate 1a, and then attach the eaves hook 2. Then, by operating the pair of nuts 11a and 11b in each eaves-hanging metal fitting 100, adjustment is made so as to optimize the relative arrangement of the support main body 6 and the vertical screw shaft 7 in the front-rear and vertical directions.

If the screw shaft 7 extends vertically above the center of gravity of the eaves bowl 2, it is possible to avoid the eaves bowl 2 from being inclined by its own weight. The tapping screw 13 fixes the folded plate 1a between the first side 8a and the second side 8b at a position in the vicinity of the extension line of the screw shaft 7. A strong fixing force can be obtained by sandwiching and fixing. In addition, since the tapping screw 13 is fixed at a position in the vicinity of the extension line of the screw shaft 7, the eaves hook suspension metal fitting 100 is fixed to the folded plate 1a in the vicinity immediately above it while supporting the weight of the eaves hook 2 vertically. It is possible to prevent bending deformation of the eaves-hanging metal fitting 100 itself.

  In the above embodiment, the third side portion 8c is connected to the upper side surface of the screw shaft 7 by welding, but a through-hole is drilled in the direct direction of the screw shaft 7 to connect the third side portion 8c to the screw shaft 7. It may be fixed to the side with bolts.

In the eaves-hanging metal fitting 200 of the second embodiment, the screw shaft 7 and the fixing portion 8 in the first embodiment are changed to a screw shaft 70 and a fixing portion 80, respectively. In the second embodiment, the third side portion 8c of the fixing portion 80 made of a bent strip-shaped steel plate is longer than that of the first embodiment, and is further bent into an L shape to provide a fourth side portion 80d. The fourth side portion 80d is provided with a hole through which the screw shaft 70 passes, and is fixed to the through hole 6c provided in the support main body portion 6 using the screw shaft 70, the nut 11b, and washers 12a and 12b. ing. Here, since the headed bolt is used as the screw shaft 70, the nut 11a in the first embodiment is not necessary. In the figure, the same reference numerals are assigned to the same fixed portions 80 as the fixed portions 8. Also in the second embodiment, the screw shaft 70 exists just above the center of gravity of the eaves rod 2, and the position of the first through hole f <b> 1 is a position in the vicinity of the extension line of the screw shaft 7.

According to the eaves-hanging metal fitting 200 of the second embodiment, there is an effect that the connection between the screw shaft 70 and the support main body 6 can be achieved by the connection between the screw shaft 70 and the fixing portion 80.
