Description

The present invention relates to a horizontal roofing material and a method for partially replacing the roofing material in a roof structure constructed using the horizontal roofing material.

A roof structure called a horizontal roof uses a roof plate material with a plate-like body whose length direction (dimension in the direction of the girder) is longer than the dimension in the width direction (dimension in the direction between the beams). It is constructed by first performing the work of connecting the roof panels, and once the connection work is completed, the work of connecting the roof panels in the direction between the beams is performed alternately up to the ridge.

As seen in Patent Document 1, roofing board materials used for such roof structures usually have a lower seam on the edge of the board body on the water side in the width direction, and a lower seam is provided on the edge of the board body on the water side in the width direction. An upper seam is provided on the edge of the roof, and the lower seam is fitted to the top seam of another roofing board located above the water, and the upper seam is fitted to the bottom seam of another roofing board located below the water. The roof structure is constructed by connecting the roof panels from the eaves to the ridge.

By the way, this type of roofing sheet material has an overhanging shape in which the bottom part of the roof sheet is particularly prominent toward the eaves. In order to replace the roof shingles in that area, an attempt was made to release the mating of the lower and upper halves of the roof shingles, but it was not easy to release the mating, and the upper and lower halves were not easily disengaged. In order to release the mating, it is necessary to remove the roof shingles located on the water side of the roof shingles to be replaced from the base material and slide them toward the eaves. It is difficult to replace the roof shingles unless all the roof shingles that were installed later have been removed, and the current situation is that efficient partial replacement of the roof shingles cannot be carried out.

The upright wall 2a can be provided with a recess 2a1 extending along the length of the plate body 1, and the top wall 2e can be provided with a recess 2e1 extending along the length of the plate body 1. It is possible to prevent rainwater from being sucked in due to the osmotic pressure phenomenon by forming an air pocket between the eave side seams 3' of the plate main body 1' of another horizontal roofing material in a fitted state. It is now possible to do so. Furthermore, a rib 2g1 extending along the length of the plate main body 1 may be provided between the hanging wall 2d and the screw 2f attachment part of the base 2g from the viewpoint of reinforcement and prevention of rainwater infiltration. good.

The ridge side seam part 2 of the board body 1 has a jaw part 2b that is linked to the eave side seam part 3' of the board body 1' of another horizontal roofing material located on the water side, especially the jaw part 3b'. When the ridge side seam part 2 is fitted into the eave side seam part 3', the roofing materials are firmly connected to each other, and even if negative pressure is applied to the board body 1, the connection is easy. It will not be canceled.

The eave side seam 3 includes a sloped wall 3a hanging down from the other edge 1d in the width direction of the board main body 1, and another horizontal wall connected to the lower end of the sloped wall 3a and located on the water side. A structure comprising a jaw 3b that can be linked to the ridge side seam 2'' of the roofing material, and a tongue piece 3c that is suspended and held at the edge of the bottom wall 3b1 of the jaw 3b is applied.

The eave side seam 3 fits into the ridge side seam 2'' of the plate body 1'' of another horizontal roofing material located below the water with springback due to its own elastic deformation. In the fitted state, the jaw portion 3b is linked to the jaw portion 2b'' of the ridge side seam portion 2'' of the plate main body 1'' of another horizontal roofing material located on the water side. The roofing materials are firmly connected to each other, and even if negative pressure is applied to the plate body 1, the connection will not be easily released.

In order to construct a roof structure using the horizontal roofing material according to the present invention, an accessory (eave starter) having the same shape as the ridge side seam 2 is attached to the base material of the eaves, and the accessory according to the invention is attached to the accessory. At the same time as fitting the eave side seam 3'' of the board main body 1'' of another horizontal roofing material having the same configuration as (not shown), the ridge side seam 2'' of the board main body 1'' is fitted. Screw the screw 2f'' into the base 2g'' and fix it to the base material.

Further, as shown in Fig. 3, the plate main body 1'' of the other horizontal roofing material that has already been fixed (this horizontal roofing material is the horizontal roofing material located below the water) is attached to the water side. A horizontal roofing material is arranged, and the eave side seam 3 of the plate main body 1 of this horizontal roofing material is fitted into the ridge side seam 2'' of another horizontal roofing material located below the water, and the ridge side Screw the screw 2f into the base 2g of the seam 2 and fix it to the base material, and repeat this operation until you reach the ridge.

In addition, when constructing a roof structure using horizontal roofing materials, it is assumed that the work of joining the roofing materials to each other is performed in advance in the length direction of the plate main body 1 of the horizontal roofing materials. FIG. 4 shows an external perspective view of a portion of a roof structure constructed using a horizontal roofing material according to the present invention.

In order to partially replace the horizontal roofing material of a roof structure constructed using the horizontal roofing material according to the present invention, basically, as shown in FIGS. 5(a), (b) and 6, , Fitting of the eave side seam 3 of the plate main body 1 of the horizontal roofing material to be replaced with the ridge side seam 2'' of another horizontal roofing material located below the water, and the ridge side seam. 2. Release the fitting with the eave side seam 3' of the other horizontal roofing material located on the water side, remove the screw 2f screwed through the base 2g, and remove the horizontal roofing material to be replaced. . Then, a new horizontal roofing material may be placed in the removed area, and the new horizontal roofing material may be installed in the same manner as shown in FIG. 3 above.

Fitting of the eave side seam 3 of the plate main body 1 of the horizontal roofing material to be replaced with the ridge side seam 2'' of another horizontal roofing material located below the water, and the ridge side seam 2 To release the fitting with the eave side seam 3' of the other horizontal roofing material located on the water side, use a lever g with an L-shaped removal jig as shown in Fig. 7. This can be done using the principle of

The horizontal roofing material according to the present invention has a high connection strength when the roofing materials are connected to each other, but the ridges of other horizontal roofing materials located below the water in the eave side seam part 3 of the board main body 1. The fitting with the side seam part 2'' and the fitting of the ridge side seam part 2 with the eave side seam part 3' of another horizontal roofing material located on the water side can be relatively easily released. Therefore, it is possible to partially replace the horizontal roofing material without requiring extra work such as removing other roofing materials.

The removal jig g includes a jig main body g1, and a hook-shaped portion at the tip that connects to the jig main body g1 and enables insertion into the space formed in the recess 2a1 of the upright wall 2a of the ridge side seam portion 2. g2, and an elastic member g3 such as rubber is installed at the lower end of the jig main body g1. If the fit between the eave side seam 3' of the material and the fit between the eave side seam 3 and the ridge side seam 2' of other horizontal roofing materials located below the water can be released. It is not limited to what is illustrated.

As shown in FIG. 8, in the jaw part 3b of the eave side seam part 3 of the plate main body 1 of the horizontal roofing material according to the present invention, a bottom wall 3b1 of the jaw part 3b and a side wall 3b2 connected to the bottom wall 3b1. It is desirable that the angle θ formed by the roof is 90° or less, and that the length L of the bottom wall 3b1 is 5 mm or more. The connection with the ridge side seam 2'' is ensured, and the connection strength between the roofing materials can be increased.

Further, the vertical height h from the bottom wall 3b1 of the jaw portion 3b to the outer surface of the plate main body 1'' is preferably set to 10 mm or more from the viewpoint of avoiding leakage.

It is possible to provide a recess K formed by bending or curving at the boundary between the jaw part 2b of the ridge side seam part 2 and the side wall 2c connected thereto. Since an air pocket can be formed between the eave side seam part 3' of the plate main body 1' of another horizontal roofing material in a fitted state, it is possible to further improve water-stopping properties (Fig. (see 2).

In addition, in the case of the partial replacement method of the horizontal roofing material described above based on FIGS. 5(a), (b) and FIG. 6, in the case of the partial replacement method according to the present invention, other embodiments as described below It is also possible to adopt

Particularly, as shown in FIG. 5(b), the partial replacement method which is another embodiment described below is when the screw 2f screwed in through the base 2g cannot be easily removed, that is, even if it is angled. Even if a screwdriver was used, the screw 2f could not be removed because the main body 1' of the roofing material located on the water side and its eave side seam 3' were not sufficiently lifted up, and as a result, the screw 2f could not be removed. If it is difficult to remove the horizontal roofing material to be replaced, a partial replacement method as described below may be used.

In summary, the partial replacement method according to this other embodiment is a method in which the entire board body 1 including the ridge side seam portion 2 and the eave side seam portion 3 of the roofing material to be replaced is removed and replaced as a whole. Where it should be, a part of it remains, that is, it is divided into a cut and removed part 1t which corresponds to the underwater side of the plate body 1 and a stationary part 1r which corresponds to the above water side, at an appropriate position in the middle, and the former (1t ), the insulation material 4 glued to the bottom surface was cut and removed, while for the latter (1r), the part of the ridge side seam 2 that corresponds to the old screwed part was left as is and the insulation material 4 was installed. The method is to put it away and reuse it.

This method will be explained below with reference to FIGS. 9 to 11. In this method, as a matter of course, it is necessary to prepare in advance a new roofing material 1n for partial repair as shown in FIG. 9, which complements the cut and removed portion 1t.

The new roof material 1n for partial repair does not form only the cut and removed portion 1t, but also includes a ridge side seam portion 2''' and an eave side seam portion 3''' in addition to the board body 1n', While supplementing the heat insulating material i pasted on the lower surface of the cut and removed portion 1t, the material on the side of the stationary portion 1r will interfere, so a removed form is prepared.

Another characteristic configuration of the newly installed roofing material 1n is that from the viewpoint of reusing the stationary portion 1r as it is, the structure of the ridge side seam portion 2'' overlaps and becomes a hindrance. The jaw 2b, side wall 2c, hanging wall 2d, ceiling wall 2e, and base 2g shown in FIG. 9(c) of the joint 2'' are cut and removed.

In addition to the above-mentioned structure, in the present invention, the ridge side seam part 2''' of the newly installed roofing material 1n and the eave side seam part 3 of the board material body 1 of the existing horizontal roofing material located above the water are provided. In order to ensure a secure fit, a cover clamp material 9 with a box-shaped cross section (approximately the shape of the upper part of the ridge side seam) as shown in FIG. I decided to intervene. The method of using it is as shown in FIGS. 10 and 11. After installing it so as to cover it over the ridge side seam part 2'' of the stationary part 1r, the main body of the roof material located on the water side The eave side seam part 3 is attached from above and fitted.

Next, the working procedure of the method for partially replacing the newly installed roofing material 1n will be explained.
(1) A part of the underwater side of the plate main body 1 of the existing roofing material to be replaced is cut and removed along with the insulation material on site, and the roofing board portion is exposed.
(2) Prepare a new roofing material 1n as shown in FIG. 9 related to the above-described configuration to be replaced.
(3) Cut off and remove a part of the upper part of the ridge side seam part 2''' of the new roofing material 1n so that it can be easily fitted with a seam joint.
(4) Lift up the eave side seam 3 of the board material body 1 of the existing roofing material on the water side using the L-shaped removal jig or the like (FIG. 9b).
(5) Attach the new roofing material 1n for partial renovation to the construction site. At that time, the surface of the existing horizontal roofing material and the back surface of the new roofing material can be bonded together.
(6) After mounting the cover clamp material 9, which is a separate member, on the ridge side seam part 2'' of the stationary roofing material 1r and covering it while pushing it in, The cover clamp 9 is fixed to the ridge side seam part 2'' by screwing in the flat head screw 10 toward the part 2''.
(7) Return the eave-side seam 3 of the plate main body 1 of the water-side roofing material that had been lifted up to its original position and fit it onto the cover clamp material 9 to attach it.

By following the steps (1) to (7) explained above, the damaged horizontal roofing material that should be replaced can be partially replaced with the new roofing material 1n.

As described above, with the horizontal roofing material according to the present invention, even if the roof structure has already been constructed, it is possible to replace only the desired part of the roofing material without removing other roofing materials. This allows for efficient partial replacement of roofing materials.

The horizontal roofing material of the present invention is basically used for constructing a roof structure, but it can also be used as an exterior material for constructing the outer wall of a building structure. In this case, the roof structure is constructed by arranging the horizontal roofing material so that the ridge side seam part 2 of the board material body 1 faces the eaves side, and the eave side seam part 3 faces the foundation side. The horizontal roofing material can be installed using the same procedure as above, and parts of the exterior material can also be replaced if necessary.
