Description

  The present invention relates to a method for laying a roof material that can be replaced with a roof extension.

  In recent years, in buildings such as houses, a flat roof material made of a lightweight material is sometimes used for the roof. Recently, the number of houses has been increased and renovated, and the number of cases in which roofs are expanded is increasing. In particular, in the extension of a roof, a flat roof material is often used as a roof material because of easy handling.

  When extending the roof, from the viewpoint of waterproofness, the structure of the connecting part between the existing roofing material and the new roofing material is important, but this type of roofing material is usually 1/2 sheet for each step. Since it is shifted from side to side and stacked from the underwater side to the upper side of the water, it is difficult to replace only a part of the roof surface in terms of waterproofing, and the entire existing roof surface is often replaced. For this reason, many waste materials of roofing material were discharged, and there was a problem that construction cost increased. And since the construction method of the roof material at the connecting portion between the existing roof material and the new roof material has not been established at present, a construction method of the roof material that can surely obtain the waterproof property is necessary. It was said.

  As a method of handling such a flat roof material, several methods have been proposed for partial repair methods when cracks or cracks occur in the roof material, such as those disclosed in Patent Documents 1 and 2, for example. Yes.

  In Patent Document 1, the rear end portion of the lower flat roof tile is screwed and fixed to the roof base material together with the fixing bracket, and the roof is overlaid so that the tip end portion of the upper flat roof tile is inserted and held in the tile fixing bracket. Describes a method for replacing flat roof tiles. In this method, a hole is made in the upper flat roof tile at the screw fixing position of the lower flat roof tile and the tile fixing bracket, the screws on the lower flat roof tile and the roof fixing bracket are removed through this hole, and the upper flat roof tile and the lower flat roof tile are removed. The tile fixing bracket is removed from between the tiles, and the lower flat tile is replaced. Then, the tile fixing bracket is inserted back into the upper plate roof tile, and the lower plate roof tile replaced with the tile fixing bracket is screwed through a hole formed in the upper plate roof tile.

In addition, in the roof tile replacement method described in Patent Document 2, first, a floating tool is inserted in the gap between the roof tile to be extracted and the normal roof tile that is overlapped therewith, and the roof tile is lifted up. Cut the roof tiles on the back of the roof tiles and remove the roof tiles. And it is set as the structure which apply | coats an adhesive agent on the surface of a normal tile, and inserts a new roof tile in the space which extracted the roof tile.

  The repair method of the roof material disclosed in Patent Documents 1 and 2 is a method of removing only one damaged roof material and replacing it with a new roof material, which becomes a problem when the roof surface is expanded, It cannot be applied to the connecting part between the roofing material and the new roofing material.

In view of the circumstances as described above, the present invention establishes a method for laying a roofing material in a connection portion between an existing roofing material and a new roofing material that are important in waterproofing as the roof surface is expanded. This construction method is intended to shorten the construction period for construction of the roof and reduce construction costs, and in addition, to reduce the amount of roofing material discarded along with the construction of the roof. It provides a method for laying roof materials that can be made.

  In order to achieve the above-described object, the present invention is such that a flat roof material is closely arranged in the left-right direction on a roofing sheet, and a lower layer roof material is laid. A roof material laying method in which a new roof surface is added to a roof surface on which an upper-layer roof material is laid out and shifted to the left and right, and a part of the existing roof material is removed and replaced with a new roof material, In the case where a new roof surface is extended on the same plane in the left-right direction as the existing roof surface, the part of the replacement area is an area from the ridge of the existing roof material to the eaves at least on the corner ridge line of the existing roof surface. The existing roofing material is removed leaving the existing roofing sheet, and the exposed nail holes are processed in the area, and then a new roofing sheet is laid, so that the overlapping method with the remaining roofing material is continuous. Laying new roofing materials The features.

  According to this configuration, the waterproofing treatment that does not oppose the water gradient in the roof flow direction is applied to the portion where the new roofing material is laid while minimizing the roofing material to be replaced with the new roofing material on the existing roof surface. And high waterproofness can be ensured.

  The present invention also provides a roof material installation method in which a new roof surface is added to the roof surface having the above-described configuration, and a part of the existing roof material is removed and replaced with a new roof material. In the case where the surface is extended so as to form a valley with respect to the existing roof surface, the partial replacement area includes at least the water area of the valley line, and the existing roof material is removed leaving the existing roofing sheet. Then, after the nail hole processing exposed in the region is performed, a new roofing sheet is laid, and the new roofing material is laid so that the remaining roofing material is continuous with the remaining roofing material.

  In the present invention, the “water area” means the entire water upper area in the roof flow direction with respect to a connection line between the existing roof surface and the new roof surface. In this way, by selecting a part of the replacement area so as to include at least the water area of the valley line, when installing a new roof material, a waterproof treatment that does not oppose the water gradient from the roof ridge to the eaves is performed. It can be applied and high waterproofness can be obtained.

  The present invention also provides a roof material installation method in which a new roof surface is added to the roof surface having the above-described configuration, and a part of the existing roof material is removed and replaced with a new roof material. In the case where the surface is extended downward in the flow direction of the existing roof surface, the partial replacement area includes at least a floating area of a connection line between the new roof surface and the existing roof surface, After removing the roofing sheet and treating the nail holes exposed in the area, laying the new roofing sheet and laying the new roofing material so that the overlapping with the remaining roofing material is continuous Features.

  Also in this invention, the waterproof treatment that does not oppose the water gradient from the ridge of the roof surface to the eaves by including at least the floating region of the connection line between the new roof surface and the existing roof surface in a part of the replacement area Can be applied, and high waterproofness can be obtained.

  In the above laying method, the existing roof material fixed to the existing roofing sheet is removed by cutting the existing roof material by bending and cutting so that the nail holes can be exposed. It is preferable that a roof material cut in the same shape as the material is laid.

According to this, by cutting the roof material, the lower nail hole of the roof material can be exposed, and the waterproof processing of the nail hole can be easily performed. Then, the roof material having the same shape as that of the cut roof material is laid against the edge of the remaining cut roof material, so that the roof material can be laid continuously by a normal process.

  In addition, in the part of the replacement area, by inserting a new roofing sheet piece between the existing roofing material that remains half of the existing roofing sheet and the existing roofing sheet, an exposed nail hole is formed. It is preferable to cover.

  As a result, by removing the existing roofing material in the replacement area, the nail hole formed under the remaining existing roofing material can be waterproofed with this roofing sheet piece, and the new roofing material and the existing roofing material are installed. It is possible to ensure waterproofness at the connecting portion with the roofing material.

  According to the roof material laying method of the present invention configured as described above, the roof material in the connection portion between the existing roof material and the new roof material, which is very important in terms of waterproofing, as the roof surface is expanded. The construction method can be established, and waterproofing can be performed so as not to oppose the water gradient from the building to the eaves, and high waterproof performance can be obtained. In addition, in the present invention, by selecting a part of the replacement area as described above depending on the form of the new roof surface, the roof material to be removed can be minimized while ensuring high waterproofness. Therefore, not only can the replacement period be shortened, but also waste such as roofing materials can be reduced.

  Hereinafter, the best mode for carrying out the roof laying method according to the present invention will be described. In the present invention, on an existing roof surface, a roofing sheet is laid on a roof base, and a flat roof material is closely arranged in the left-right direction on the roofing sheet, and a lower layer roof material is laid. Further, with respect to the lower layer roof material, the upper layer roof material is laid so as to be shifted to the left and right by 1/2 of the roof material. The present invention is a roof material laying method in which a new roof surface is added to the roof surface in such a form, and a part of the existing roof material is removed and replaced with a new roof material.

  1 to 8 show Embodiment 1 of the present invention. In the first embodiment, an example in which the roof material laying method of the present invention is applied to a case where a new roof surface is extended on the same plane in the left-right direction as the existing roof surface will be described.

  As shown in the drawing, on the existing roof surface 1 in a dormitory shape, the upper layer roofing material is laid so as to be shifted to the left and right by 1/2 of the lower layer roofing material. The roofing material 3 is fixed by nails 8 to the roof base on which the roofing sheet 2 is laid. In the present embodiment, a new roof surface 4 is extended so as to extend rightward from the corner building line 11 with respect to such an existing roof surface 1.

  The existing roofing material 3 is partly removed from the roof surface 1 and replaced with a new roofing material. However, in the illustrated embodiment, the existing roofing material 31 extends over at least the corner building line 11 of the existing roofing surface 1. ... selected to include the area from 31 ridges to the eaves. The existing roof materials 31... 31 that hang over the corner building line 11 are partially cut in accordance with the corner building line 11, and those that do not have the full shape are laid. Therefore, in this embodiment, the existing roof material 31... 31 laid in the reshuffling area 10 shown by hatching in FIG. 2 is all removed, and a new roof material is laid.

The removal of the roof materials 31... 31 is sequentially performed from the roof material 31 laid in the upper layer row in the rearrangement region 10. For example, as shown in FIG. 3, a nail removal tool such as a ripper (not shown) is inserted into an overlapping portion between the roof material 31 a and the roof material 32 laid thereon, and the roof material 3.
By removing or cutting the nail 8a fixing the la, the roof material 31a can be extracted. And the roof material 31a is pulled out in the roof flow direction, leaving the existing roofing sheet 2 laid under the existing roof material 31a. Subsequently, all the other existing roof materials 31... 31 hanging on the corner building line 11 are removed by the same procedure (see FIG. 4).

  In this way, when all the existing roof materials 31... 31 included in the partial replacement area 10 are removed on the roof surface 1, next, the waterproof processing of the nail holes 81 exposed in the alternative area 10 is performed. As a result of the above-described nail removal operation, the remaining half of the existing roofing materials 32... 32 are lifted from the existing roofing sheet 2 in the right half of the figure. Therefore, as shown in FIG. 5, a new roofing sheet piece 61 is inserted between the raised existing roofing materials 32... 32 and the existing roofing sheet 2 to cover the nail hole 81a formed after the nail is removed. It is made waterproof.

  For the roofing sheet piece 61, a roofing sheet having a width W cut to about 1500 mm is used. The roofing sheet pieces 61 are laid in order from the lower layer row to the upper layer row so as not to oppose the water gradient. Here, the overlapping width T between the roofing sheet pieces 61 in the upper layer row and the lower layer row may be ensured to be 100 mm or more.

  Subsequently, the new roofing sheet 6 is laid on the new roof surface 4 so as to overlap the inserted new roofing sheet piece 61. The overlapping width t between the new roofing sheet 6 and the roofing sheet piece 61 is preferably secured to about 200 mm.

  Next, as shown in FIG. 6, the new roofing material 5 is laid on the new roofing sheet piece (61) and the roofing sheet (6) so as to overlap the existing roofing material 3. . At this time, an adhesive is applied to the nail head peripheral portion 82 of the existing roof material 3 that overlaps the new roof material 5, and then the new roof material 5 is inserted and fixed.

  Through the above steps, the installation of the roofing material accompanying the extension is completed. Thus, since the roofing sheet piece 61 is laid at the lower part of the new roofing material 5 laid in the reshuffling region 10, in the connection portion between such a new roofing material 5 and the existing roofing material 3. Even waterproof performance can be obtained with certainty.

  By the way, when there is an existing roof material fixed to the existing roofing sheet 2, as shown in FIG. 7, a cut groove 30 is provided in the fixed roof material 33 so that the nail hole 81 can be exposed. It can respond by bending and cutting. The kerfs 30 are preferably formed in the roof material 33 in the roof flow direction, outside the edge of the adjacent roof material 34 that overlaps (on the right side in the figure) and at a position where the nail hole 81 is exposed. . As a result, the roof material 33 fixed to the roofing sheet 2 can be partially removed (the hatched portion in the figure), and the nail hole 81 at the bottom of the roof material 33 is exposed. 81 waterproofing treatment can be performed. In this case, these nail holes 81 are waterproofed by being filled with a sealing agent.

  Further, as shown in FIG. 8, a new roofing sheet piece 61 is laid on the edge of the cut roof material 33 and the other nail holes 81 are also covered to be waterproofed. Subsequently, the roof material 35 having the same shape as the existing roof material 33 cut and removed is laid so as to abut against the edge of the partially cut roof material 33. In this way, even when the existing roof material 33 is fixed to the existing roofing sheet 2, the roof material can be installed with improved waterproofness at the connection portion between the existing roof surface 1 and the new roof surface 4. It can be carried out.

  9 to 14 show a second embodiment of the present invention. In the second embodiment, as shown in FIG. 9, a case where the new roof surface 4 is extended so as to form a valley with respect to the existing roof surface 1 will be described as an example.

  About the roof surface in which a trough is formed between the new roof surface 4 and the existing roof surface 1, the replacement region 10 for replacing a part of the existing roof material 3 has at least the water region of the valley line 12. It is supposed to include. Here, the “water area” means the entire water upper area in the roof flow direction with respect to the connection line between the existing roof surface 1 and the new roof surface 4.

  That is, in the roof surface 1 of this form, as shown in FIG. 10, all of the roof materials 36... 36 laid on the existing roof surface 1 in the water-side region of the valley line 12 are included in the reshuffling region 10. In the illustrated embodiment, the roof material 36 including one roof material 36a on the valley line 12 is included in the replacement area 10, and the existing roof materials 36... 1 and remove the existing roofing sheet 2 (see FIG. 11). At this time, the nail 8 which fixes the existing roof material 36a which overlaps the lower part of the existing roof materials 37 ... 37 is removed, respectively, and the existing roof materials 36a ... 36a in the rolling area 10 are pulled out.

  Subsequently, a valley roofing sheet 62 is laid along the valley line 12 as shown in FIG. With this valley roofing sheet 62, after securing the waterproofness in the valley, between the existing roofing sheet 37 ... 37 and the existing roofing sheet 2, which remains half of the existing roofing sheet 2, A new roofing sheet 6 is inserted and laid in order from the underwater side, and the nail hole 81 is waterproofed.

  Next, as shown in FIG. 13, on the new roofing sheet (6, 62) laid on the existing roof surface 1 and the new roof surface 4, the remaining roof material 3 ... 3 is overlapped. New roofing materials 5 ... 5 are laid in a continuous manner. Further, the adhesive is applied to the nail head peripheral portion 82 of the existing roof material 37 that overlaps the new roof material 5, and then the new roof material 5 is inserted to complete the installation of the roof.

  Thus, when the new roof surface 4 is extended so as to form a valley with respect to the existing roof surface 1, the existing roof material 3 is not removed only along the valley line 12, but the valley By removing the entire roofing material 36 included in the water region of the line 12 and installing a new roofing material 5, it is possible to perform a waterproofing process that does not oppose the water gradient of the roof surface, and a reliable waterproofing performance. Be able to get.

  In addition, in the roof surface 1 having such a configuration, when there is an existing roof material fixed to the existing roofing sheet 2, as shown in FIG. This is done by bending and cutting so that the nail hole 81 is exposed. Also in this case, as shown in the first embodiment, a kerf is formed in the roof material 38 in the roof flow direction, outside the edge of the adjacent roof material 39 that overlaps (left side in the figure), and a nail hole. 81 is provided at a position where it is exposed, and the fixed roofing material 38 is partially cut and removed.

Of the exposed nail holes 81, the nail holes 81b... 81b within a range of about 200 mm from the edge of the cut roof material 38 are preferably waterproofed by filling with a sealing agent. Subsequently, a new roofing sheet 6 is laid so as to cover the nail holes 81b... 81b filled with the sealing agent and the exposed nail holes 81. . Then, by laying a roof material having the same shape as the cut existing roof material 38 on these new roofing sheets 6, it is possible to take a normal roof material installation process.

  FIG. 15 shows Embodiment 3 of the present invention. In Example 3, the roof material laying method of the present invention is applied to a case where a new roof surface 4 is extended downward in the flow direction of the existing roof surface 1 as shown in FIG. explain. In the description of the third embodiment, the step of laying the roofing material is the same as in the first and second embodiments, and there is a characteristic in a partial replacement area of the roofing material. Therefore, the replacement area will be described. .

  In such a roof surface 1, the replacement area 10 is selected so as to include at least the water area of the connection line 13 between the new roof surface 4 and the existing roof surface 1. In the illustrated embodiment, in consideration of the arrangement of the roofing material laid on the existing roof surface, not only the water upper right portion of the connection line 13 between the new roof surface 4 and the existing roof surface 1 but also the water region It is a respreading area that extends slightly in the direction. The new roof material is laid such that the existing roof material is overlapped with the remaining roof material through processes such as nail hole processing and laying a new roofing sheet after removing the existing roof material in the rearrangement region 10. .

  Thus, the existing roof material is removed so as to include the floating area of the connection line 13 between the new roof surface 4 and the existing roof surface 1, and the new roof material is laid, thereby extending the roof surface in this form. The water-proofing process that does not oppose the water gradient can be performed, and a reliable waterproofing performance can be obtained.

  The present invention provides a high waterproof property at a connection portion between a new roof surface that is important for a waterproof surface and an existing roof surface when the roof surface is expanded in an expansion and renovation of a house that has been increasing in recent years. It can be used effectively to secure.
