Description

  The present invention relates to a fitting type metal roof plate improved so that roof roof construction can be easily and quickly performed, a fitting type roof structure using the roof plate, and a construction method thereof.

  Conventionally, as a method of roofing, a rake side fitting portion provided at one side edge in the width direction of a metal roof plate is fitted into a metal fitting attached at regular intervals on a roof beam. The rake side mating part is fitted with the cover side mating part provided on the side edge of the other adjacent roof plate in an overlapping manner, and thus the metal roof plates are sequentially connected to each other in a boltless state (fitting type) ), A construction method for raising the roof is known (Patent Documents 1 and 2).

  In such a fitting-type roofing structure, the receiving metal fittings are mounted on the beam at regular intervals. For example, in Patent Document 1, a portion with the receiving metal fitting is covered with the rake side fitting part. When the side fitting part is firmly fitted and when the cover side fitting part is pressed for fitting even when there is no receiving metal fitting, the rake side fitting part shows the fulcrum A as shown in FIG. Although it bends downward as a starting point, the cover side fitting portion and the rake side fitting portion can be easily fitted.

  However, in the roofing structure of Patent Document 1, when upward pressure is generated on the main plate portion due to wind blowing, a rotational moment is applied to the free end B of the rake side fitting portion from the fulcrum A as a starting point. There is a possibility that the fitting portion may be easily detached when the end B is easily detached or when the operator walks on the roof and a downward pressure is generated.

  On the other hand, in patent document 2, since the rake side fitting part and the covering side fitting part which are the junction parts of roof boards have both jaw fitting structures, it was stable also against the negative pressure after fitting. Although it has strength, since it is necessary to fit with the left and right jaws open, a larger pressing force is required and there is a problem that the burden of the fitting work on the operator is large.

  Moreover, in the case of the fitting structure of patent document 2, when fitting the free end B of a rake side fitting part, the fitting press equivalent to the width of (l + l ') as shown in FIG.1 (b) is carried out. If it is necessary and there is no bracket, it may not be able to fit completely.

Moreover, in the construction work of such a fitting type metal roof plate, since it cannot be distinguished from the outside at the time of construction, it was impossible to visually confirm whether the roof plate fitting structure is good or bad.

The second hook side 50 is formed by bending outward from the upper edge of the rising side 49 and projecting downward.

  Then, similarly to the roof plate fitting structure of FIG. 4, the first convex portion 11 of the covering side fitting portion 4 of the one roof plate 1 is fitted to the first fixing portion 32 ′, and the second fixing portion 33. On the rake side fitting portion 3 of the other roof plate 1 and the second convex portion 12 of the covering side fitting portion 4 of the roof plate 1 so as to be further covered on the fitting portion 3. By fitting, the fitting type roof structure of the present invention can be constructed. The roof plate 1, 1 ′ is supported by the top side 46 of the first fixing part 32 ′ of the upper fixing bracket 30 and the top part of the second fixing part 33 ′ and hooked by the first fixing part 32 ′. The protrusions of the fitting jaws 6, 14, and 22 of the rake side fitting portion 3 and the covering side fitting 4 are fitted to the tip of the side 47 and the hooking side 50 tip of the second fixing portion 33 ′. Thus, it is firmly fixed via the metal fitting F.

  As in the case of the metal fitting F in FIG. 4, the reinforcing flange 30 is in contact with the main plate 43, the metal first inclined side 44, and the metal second inclined side 48 at the end in the longitudinal direction of the upper fixing metal 30. 65 is preferably provided. The reinforcing flange 65 is used to prevent the first fixing portion 32 ′ and the second fixing portion 33 ′ from being inclined in the vertical direction by pressing when the roof plates 1 and 1 ′ are fitted to the upper fixing bracket 30. It is provided.

In the present invention, as shown in FIGS. 4 and 5, two fitting convex portions, that is, a first convex portion 11 and a second convex portion are provided on the covering side fitting portion 4 of the roof plate 1 through the central concave portion 18. A portion 12 is provided, and the first convex portion 11 is firmly fitted to the metal fitting F, and the second convex portion 12 is used to firmly secure the metal fitting F and the rake side fitting portion of the other roof plate 1 ′. It is comprised so that it may fit.
Thereby, both the 1st convex part 11 and the 2nd convex part 12 of the covering side fitting part 4 become a single jaw structure, and it fits easily with the metal fitting F and the rake side fitting part 3 with a small press (elastic force). And the position of the free end portion of the rake side fitting portion 3 is closer to the hooking side 23 of the covering side fitting portion 4 serving as a fulcrum of the rotational bending moment than in the prior art (FIG. 1). The rotation bending moment acting on the rake side fitting portion 3 is small, and even when a pressure is applied to the main plate portion 2 of the roof plate 1, the rake side fitting portion 3 can be prevented from rotating.

  Moreover, in the fitting type roof structure of this invention, the covering side 2nd rising edge 20 which is a substantially perpendicular inner wall in the extension position of the center recessed part 18, and the inclination inner side 9 of the rake side fitting part 3 are long. It is formed so as to extend along the vertical direction. For this reason, the covering side second rising side 20 of the covering side fitting part 4 and the inclined inner side 9 of the rake side fitting part 3 support the pressure applied to the main plate part 2 of the roof plate 1, 1 ′ from the side. Even if a strong reaction force (wall reaction force) is exerted and a large negative pressure is applied by a strong wind or a typhoon, the roof plate 1, 1 'is lifted and does not rotate, and the fitting state is always constant. Can be held.

  In addition, when the covered side fitting portion 4 of the roof plate 1 is superimposed on the rake side fitting portion 3 of the roof plate 1 ′, the rising side 20 of the covered side fitting portion 4 is the rake side fitting portion 3. Since the inclined inner side 9 is fitted so as to be supported from the side, the rising side 20 serves as a support wall, and therefore the rake side fitting portion 3 is attached to the covered side even in a portion without a receiving bracket. It is not pushed down, rotated, or sinks by the fitting pressure by the fitting part 4.

  Further, in the present invention, the inclined inner side 9 of the rake side fitting part 3 is inclined to the fitting jaw part 6 side, so that the rake side fitting part fitted to the second fixing parts 33 and 33 ′ is used. 3 is difficult to slip off, and when the rake side fitting jaw portion 6 and the covered second fitting jaw portion 22 are fitted, the rising side 20 of the covered side fitting portion is fitted to the rake side. There is an effect that it is easy to drop along the inclined inner side 9 of the portion 3.

  Furthermore, in the present invention, a gap 52 is formed between the rake side fitting part 3 and the covered side fitting part 4 by providing the rake side fitting part 3 with the inclined outer side 7 and adding a recess. This gap 52 serves as an air layer, and can prevent water from entering the cover side hook side 23 due to capillary action.

  Moreover, since the hook side 10 of the rake side fitting part 3 is formed so as to open to the outside, the rake side fitting part 3 can be easily dropped into the second fixing parts 33 and 33 ′ of the bracket F. In addition, since the inclined sides 17 and 19 are provided in the covering side fitting portion 4 and the lower portions of the first and second convex portions 11 and 12 are opened, the covering side fitting portion 4 is attached to the bracket F. And it is easy to drop into the rake side fitting part 3.

The roof plate 1 ′ is pressed by stepping on the roof plate 1 ′ so that the main plate portion 2 becomes substantially horizontal, and at the same time, the rake side fitting jaw portion 6 and the metal fitting second jaw 40 of the metal fitting F are connected to rainwater or wind. It is securely fitted so as to prevent the intrusion (FIG. 8C).

  In the second step, the other fitting-type metal roofing board 1 is arranged such that the first convex portion 11 and the second convex portion 12 of the covering side fitting portion 4 are the first fixing portion 30 of the upper fixing bracket 30 after the first step. The first fixing part 32 and the second fixing part 33 are placed so as to be positioned, and then the covered first convex part 11 of the roof plate 1 is pushed down and fitted into the first fixing part 32 of the bracket F. At the same time, the covering side eleventh fitting jaw 14 and the metal fitting first jaw 36 are fitted together. Then, the roof plate 1 is turned until the second convex portion 12 on the roof plate 1 is superimposed on the rake side fitting portion 3 that is fitted onto the upper fixing bracket 30 in the first step. (FIG. 8D).

Next, in the third step, first the cover side second rising edge of the cover side second convex portion 12 on the rake side fitting part 3 side, that is, the second fixing part 33 side of the upper fixing bracket 30, is firstly covered. 20 side is pushed down so as to be along the inclined inner side 9 of the rake side fitting portion 3, and then the outer side second fitting jaw portion 22 side is pushed down, thereby the covering side fitting jaw portion 22 and The rake side fitting jaw portion 6 and the metal fitting jaw 40 are fitted together (FIG. 8 (e)), and the rake side fitting portion 3 and the covering side fitting portion 4 of the roof plate 1, 1 'to the upper fixing bracket 30 are fitted. A roof gutter is performed by overlapping with.
Thereby, the rake side fitting part 3 does not sink by the fitting press of the covering side fitting part 4, and roofing construction can be performed easily and reliably with a small pressure.

Next, a method for constructing a roof as shown in FIG. 3 by fitting the roof plates 1, 1 ′ to the upper fixing bracket 30 of FIG. 7 will be described.
First, in the first step, the rake-side fitting portion 3 of one fitting-type metal roof plate 1 ′ is placed on the second fixing portion 33 ′ of the upper fixing fitting 30, and then the roof plate 1 ′. The rake side hooking side 10 is dropped while being wrapped so as to overlap with the second inclined side 48 of the second fixing portion 33 ′, and then the roof plate main plate portion 2 is rotated in the width direction (left-right direction). At the same time, the top portion of the rake side fitting portion 3 is pressed with a foot or the like so that the main plate portion 2 of the roof plate 1 ′ becomes substantially horizontal, and at the same time, the rake side fitting jaw portion 5 and the second portion.
