Ventilation holes 112 are formed between the upper surface of the main plate 32 of the object 31 with a predetermined interval, and a ventilation structure that vents air from the ventilation holes 112 through the ventilation layer 111 is often used. This ventilation structure is used to prevent the occurrence of condensation inside the wall body 108 in recent buildings with high airtightness. Even with such a ventilation structure of the wall 108, a roof structure that appropriately guides rainwater to the fence 106 without flowing rainwater into the ventilation layer 111 is required. Note that the wall stopper 1 of the present invention can also be used for the wall body 108 that does not have the ventilation structure.

  As shown in FIG. 2, the wall stopper 1 used in the roof structure of the present invention mainly includes a bottom plate 2, a vertical plate 3 rising from the side of the bottom plate 2, and an eave direction side of the bottom plate 2 (FIG. 2 (a ) On the right front side of FIG. 2B and the left front side of FIG. 2B, and a groove portion 5 formed between the bottom plate 2 and the guide plate 4. The wall stopper 1 in this embodiment uses a galvanium steel plate, but other materials may be used instead of this material.

  As shown in FIG. 3, the wall stopper 1 according to the present embodiment is formed by cutting a single steel plate under a predetermined dimension and then bending the same. Specifically, the vertical plate 3 is raised by valley-folding the fold line between the bottom plate 2 and the vertical plate 3 among the cut steel plates. Fold the folding line between the folded plate 7a and the vertical plate 3 and fold the folded line between the folded plates 7a and 7b so that the two folded plates 7a and 7b overlap the back side of the vertical plate 3. The folding line between the stop piece 7c and the push-back plate 7b is valley-folded and overlapped with the upper edge of the vertical plate 3, and the overlap between the turn-back plates 7a and 7b and the vertical plate 3 is locked.

  In addition, the fold line between the bottom plate 2 and the inclined surface 6 is fold-folded, and the fold line between the inclined surface 6 and the groove portion 5 is fold-folded. Can be formed. And the fold line between the groove part 5 and the guide plate 4 is valley-folded, and the guide plate 4 is raised. As described above, the wall stopper 1 according to the present invention is formed by bending each of steel plates cut into a predetermined size, but is not necessarily limited thereto. For example, the guide plate 4 and the groove 5 May be fixed by welding or other molding methods.

  As shown in FIG. 2, the bottom plate 2 of the wall stopper 1 that locks the folded state is a flat plate-like portion disposed on the upper surface of the inclined roof 103, and the eave direction side (of FIG. 2 (a)). An inclined surface 6 and a groove portion 5 are formed on the right front side, the left front side in FIG. The inclined surface 6 is a portion that is once bent into a substantially triangular shape by partially bending a part of the bottom plate 2 in the eave direction side, and is further formed with a groove portion 5 having a flat eave direction side. The groove portion 5 is positioned lower than the bottom plate 2 due to the inclined surface 6, and the groove portion 5 is located above the ridge 106 when the wall stopper 1 is constructed, and guides running water to the ridge. (See Figure 1)

  The vertical plate 3 of the wall stopper 1 is a surface that rises upward from one side edge of the bottom plate 2. The folded plates 7a and 7b are located on the back side of the vertical plate 3, and the bent state is locked by the locking pieces 7c. As will be described later, the vertical plate 3 is disposed so as to be joined to the structural wall 107.

  The guide plate 4 of the wall stopper 1 that is locked in the bent state has an eave direction side edge of the groove portion 5 as a lower side, an eave direction side edge of the vertical plate 3 as a side side, and an eave direction side edge of the bottom plate 2. It is located so as to face each other. When it is substantially opposed, the guide plate 4 is formed so as to face (oppose) the flowing sewage flowing on the bottom plate 2, but it does not necessarily face exactly and the guide plate 4 You may make it open direction to the right side of Fig.2 (a). Thereby, the rebound which generate | occur | produces at the time of the guidance | induction of the flowing water which flows through the surface of the rain holding | maintenance accessory 31 arrange | positioned on the baseplate 2 can be decreased.

  Of the bottom plate 2 of the wall stopper 1 that is locked in the bent state, the side edges without the vertical plate 3, the upper edge of the vertical plate 3, and the upper edge of the guide plate 4 are folded back, respectively. Bend to form. With this maple 2a, 3a, 4a, it is possible to avoid injuries such as the operator cutting his hand and to prevent a part of running water from flowing out.

  A part of the guide plate 4 is extended to form the defense wall 11. A part of the upper edge of the guide plate 4 in the vicinity of the vertical plate 3 is extended downward to once form a flange 12 that bends in the direction of the rain retainer 31, and further bent downward to form the hanging wall 13. Form. Thereby, a part of surface of the guide plate 4 is located on the bottom surface 2 side. In this embodiment, a part of the upper edge of the guide plate 4 is extended to form the defense wall 11, but the upper end edge of the guide plate 4 may be extended to form a defense wall.

  As shown in FIG. 4, as another embodiment, the defense wall 11 is formed by molding the defense wall 11 itself as a separate member from the guide plate 4 and fitting it into the upper edge of the guide plate 4. Also good. This forms a hook-shaped fixing portion 14 at the upper end edge of the defense wall 11, and the fixing portion 14 is fitted into the arrangement portion of the upper end of the guide plate 4. In addition, it may be arranged and fixed by welding or screws.

  As other embodiments of the defense wall 11, although not shown in the drawings, the heel portion that does not extend downward from the upper end edge of the guide plate 4 and extends in the direction of the rain retainer 30 at the same height as the upper end edge of the guide plate 4. 12 may be included.

  In addition, the bending with the hanging wall 13 that extends and bends from the tip of the flange 12 of the defense wall 11 is bent at an acute angle with an angle of about 10 degrees rather than a right angle. It is not limited and may be bent at a right angle or slightly obtuse. In addition, as another embodiment, the embodiment which is only the collar part 12 which does not have the hanging wall 13 may be sufficient.

  The length in the lateral direction (width direction / left-right direction in FIG. 4) of the flange portion 12 and the hanging wall 13 of the defense wall 11 is preferably about 40 mm, but is not limited thereto. The lateral length of the defense wall according to another embodiment may have a length of about one third to one quarter of the lateral length of the guide plate 4. The length may be the same as the length in the direction, or about one-half, or even about one-sixth of the length.

  The position of the defense wall 11 is at least a portion extending from the lower end 102 a of the outer wall 102 along the inclination direction of the inclined roof 103, and is in a position facing the outer wall 102. This is because, as will be described later, the main purpose of the defense wall 11 is to prevent the small flow sewage C1 from bouncing back and appropriately guide it to the trough 106 (see FIG. 11).

  Further, the guide plate 4 is formed with an upper extension 21 extending upward in the vertical direction (vertical direction in FIGS. 2A and 2B) as compared with the conventional guide plate, and in the lateral direction (FIG. 2A). ), A lateral extension 22 extending to the left in the left-right direction of (b) is formed. The upper side extension 21 and the side side extension 22 will be described later.

The construction of the roof structure using the wall stopper 1 according to the present invention shown in FIG. 2 (a) will be described with reference to FIGS. As the arrangement and fixing means of each member, a commonly performed means such as nailing, screw fixing, and adhesion is used. The wall stopper 1 of the present invention shown in FIG. 2 (b) is constructed at a symmetrical position, and the construction method is the same.
In addition, in the adjacent parts 105 and 105 shown in FIG. 12, the wall 108 is further extended in the eaves direction (left-right direction of FIG. 12) from the position which arrange | positions the wall stopper 1. However, in FIG. 1, FIG. 6 to FIG. 9, and FIG. 11, the one in which one end of the wall body 108 is located at the position where the wall stopper 1 is arranged is shown for explanation of construction. When the wall 108 is further extended in the eave direction, the cutout portion 41 and the sealing 42 of the outer wall 102 of the wall 108 for securing the arrangement portion of the wall stopper 1 are shown in FIG. 10 and will be described later.

  As shown in FIG. 6, a sheet-like underlaying material 122 is pasted from the base plate 121 of the inclined roof 103 to the lower end portion of the structural wall 107. The wall stopper 1 is attached to the eaves side in the vicinity of the adjacent of the inclined roof 103 and the structural wall 107 in a state where the underlaying material 122 is stretched. The groove portion 5 of the wall stopper 1 is exposed from the eaves side of the inclined roof 103 and is positioned so as to be on the upper side of the eaves 106 (omitted). In this embodiment, although fixed using the hanging clasp members 8 and 8 attached to the structural wall 107 side and the sloped roof 103 side of the wall stopper 1, the hanging clasp members 8 and 8 are used directly. It may be fixed with screws or nails.

  As shown in FIGS. 6 and 7, a square wood receiving bar 123 is disposed in the vicinity of the joint with the structural wall 107 from above the underlaying material 122 attached to the inclined roof 103. Next, the discard drainer 124 is disposed so as to cover the receiving bar 123. The waste plate drainer 124 has a central portion 124b that covers the receiving bar 123, a portion that rises upward from the side thereof is disposed on the side of the lower brazing material 122 that is attached to the structural wall 107, and a flange portion that extends to the other side. 124 a is disposed on the lower covering material 122 attached to the base plate 121 of the inclined roof 103.

  The roof material 125 is spread and fixed from above the lower covering material 122 of the inclined roof 103. The roof material 125 is positioned near the wall portion 108 so as to overlap the brim portion 124 a of the discard drainer 124, but does not overlap the central portion 124 b of the discard drainer 124.

  A square headboard 126 is arranged so as to be positioned above the central portion 124b of the discarded plate drainer 124. Then, the rain retainer accessory 31 is arranged so as to cover the headboard 126. The rain retainer 31 has a main plate 32 covering the upper side of the headboard 126, and a vertical plate 33 rising from the side is in contact with the lower brazing material 122 attached to the structural wall 107 and extends from the other side. The flange portion 34 touches the upper surface of the roof material 125.

  As shown in FIG. 5, the rain retainer 31 includes a main plate 32 having a predetermined length in the longitudinal direction, a vertical plate 33 formed by bending a side edge of the main plate 32 upward, and a main plate 32. The flange 34 is formed by bending the side edge without the vertical plate 33 once downward and further bending and extending in a direction parallel to the main plate 32. The burrs 33a and 34a are formed by folding back the upper edge of the vertical plate 33 and the edge of the flange portion 34, and are arranged so as not to injure the installer.

  As shown in FIGS. 8 and 9, the outer wall 102 is located above the main plate 32 of the rain retainer accessory 31, but the lower end 102 a of the outer wall 102 is not in contact with the main plate 32 of the rain retainer accessory 31. This portion is released, and this portion becomes a vent 112 that leads to the vent layer 111. The ventilation layer 111 between the outer wall 102 and the structural wall 107 is arranged so that the vertical plate 33 of the rain retainer 31 and the vertical plate 3 of the wall stopper 1 are incorporated in contact with the structural wall 107. The

  A description will be given of sealing performed by partially cutting out the outer wall 102 of the wall body 108 at the portion where the wall stopper 1 is disposed, and preventing rainwater or running water from entering the ventilation layer. As shown in FIG. 10, the wall stopper 1 is arranged, and in particular, the outer wall 102 is partially cut away to form a cutout portion 41 in order to secure the arrangement portion of the guide plate 4. After the wall stopper 1 is placed, the cutout portion 41 is filled with a backup material and a sealing 42 is applied. Conventionally, since the sealing 42 is applied to the entire notched portion of the outer wall 102, it has been time-consuming, such as damming it so as not to hang down with a curing tape or the like. However, since the collar portion 12 of the defense wall 11 of the wall-stopping member 1 of the present embodiment serves as a receptacle for the sealing 42 and a guide for the backup material, the sealing 42 is easily and cleanly applied including the spatula pressing step. Is possible.

  The guidance of flowing water in the roof structure using the wall stopper 1 of the present invention will be described. As shown in FIG. 11, since the surface of the main plate 32 of the rain retainer 31 is generally a metal plate, wind and rain flow more easily than the roof material 125 without resistance. Therefore, in a severe weather environment accompanied by intense wind and a large amount of wind and rain, main plate flow sewage A1 in which the wind and rain flow in the direction of the arrow line A1 is generated. It is necessary to appropriately guide the main plate flow sewage to the trough 106 and prevent it from flowing into the structural wall 107 side.

  It has been found that not only the main plate flowing sewage A1 but also the surface of the brim part 34 generates the brim part flowing sewage B1 through which wind and rain flow. The brim portion 34 is also generally a metal plate, like the main plate 32, and has less resistance than the roofing material 25, and wind and rain easily flow.

  In addition, as the brim portion flowing sewage B1, the diffused flowing sewage B2 that flows spreading to the right front side is generated on the eaves end side of the rain presser accessory 31. Normally, the brim portion flowing sewage B1 flows on the surface of the brim portion 34 to the ridge 106, flows into the ridge 106, and flows along the direction of the arrow line D. However, it has been found that when the weather conditions deteriorate and the flow rate increases, the water diffuses radially along the flowing water flowing in the direction of the arrow D in the vicinity of the inflow to the eaves 106. This diffusion sewage B2 also needs to be appropriately guided to the trough 106.

  Furthermore, when the lower roof is a sloped roof, it has been found that small-mouth flow sewage C1 is generated by the sewage from the outer wall 102. This small-mouth flow sewage means that in the wall body 108 having the ventilation layer 111, a large amount of wind and rain flows along the lower end 102a of the outer wall 102 toward the eaves direction (the arrow direction of C1).

  In order to appropriately guide these rainwaters to the fence 106, the guide plate 4 of the wall stopper 1 is formed with an upper extension 21, a side extension 22, and a defense wall 11 as compared with the conventional guide plate. And That is, the height (vertical direction in FIG. 11) is at least a gradient angle of the inclined roof 103 from the surface of the main plate 32 of the rain retainer 31 in order to cope with the main plate flow sewage A1 whose flow rate has increased significantly. It is necessary to extend in the eave direction along and to be higher than the portion A3 that hits the surface of the guide plate 4.

  Further, in order to cope with the small-mouth flow sewage C1, the height of the guide plate 4 is extended at least from the lower end 102a of the outer wall 102 in the eave direction (the arrow direction of C1) along the gradient angle of the inclined roof 103, It is necessary to be higher than the portion C3 that hits the surface of the plate 4. The position of C3 is higher than the position of A3 in the case of a general guide plate, but this condition must be satisfied depending on the form of the guide plate.

  As with the main plate flow sewage A1, it extends from the surface of the brim portion 34 to the eave direction along the gradient angle of the inclined roof 103 and is higher than the portion B3 that hits the surface of the guide plate 4 in order to deal with the brim flow sewage B1. is necessary.

  The guide plate 4 forms the upper extension 21 so as to be higher than the positions of A3, B3, and C3. Due to the presence of the upper extension 21, the main plate flow sewage A1, the brim flow sewage B1 and the small-mouth flow sewage C1 whose flow rates are increased can be appropriately guided to the eaves 106 without getting over the guide wall 4.

  Table 1 shows the results of the experiment conducted by dividing the amount of flowing water with respect to the height of the upper extension 21, the amount of supplied water, and the drought induction rate. In addition, the guide plate height in the table indicates the height of the guide plate 4 from the surface of the main plate 32 of the rain retainer 31, and the exterior material insertion height indicates the height of the guide plate 4 from the lower end 102 a of the outer wall 102. Indicates. In this experiment, a 1200 mm pipe with small holes arranged at intervals of 10 mm to be evenly sprayed on an inclined roof is placed 200 mm away from the eaves, and the water pressure is controlled in order to keep the amount of flowing water constant, It was allowed to flow down linearly. The amount of flowing water was 4 liters per minute (corresponding to general rain) and 8 liters (corresponding to summer evening), and the measurement time was 5 minutes.

  From the above experimental results, it can be seen that in the absence of the upper extension 21 having a predetermined height, the water does not flow properly over the guide plate 4 when the amount of water is large. The height of the guide plate is preferably 25 mm when the vent hole width is 15 mm. In general, since the vent 112 takes a height of about 10 to 15 mm, the upper extension 21 of 10 to 15 mm from C3 is formed.

  Further, in order to deal with the diffused sewage B2 in the brim portion 34, the length of the guide plate 4 in the lateral direction (the right front direction in FIG. 11) is the same as the direction in which the brim portion 34 of the rain retainer accessory 31 extends. A lateral extension 22 is formed.

  In the conventional guide plate, the lateral direction does not reach the position corresponding to the tip of the brim portion of the rain retainer. This is because the presence of the diffused sewage water B2 was not conscious and there was no intention to respond to it. A lateral extension 22 that extends the lateral length of the guide plate 4 is formed from B4.

  Specifically, the length in the width direction from the end where the vertical wall 33 of the general rain retainer 31 is formed to the tip of the flange 34 is 130 mm, and the length in the width direction of the guide plate 4 is It is preferable to form a length of 150 mm and form a lateral extension 22 of 20 mm.

  The defensive wall 11 has an effect that it can be guided to an appropriate ridge 106 of the flowing water. In other words, since the flange portion 12 of the defense wall 11 is formed in the direction of the rain retainer 31 from the guide plate 4, it is possible to prevent the spring 106 from jumping up when the flow rate is large. Moreover, the lower end 13a of the hanging wall 13 of the defense wall 11 is located above the position (C3) extending from the lower end 102a of the outer wall 102 to the guide plate 4 along the inclination direction of the inclined roof. As a result, even when the small-mouth flow sewage C1 flows, the lower end 13a of the defense wall 11 functions like a drainer and can be appropriately guided to the eaves 106, and is rebounded by the guide plate 4 to be ventilated. Intrusion of running water to 111 can be prevented. As described above, the small-mouth flow sewage C1 is located above the main plate flow sewage A1 and flows along the lower end 102a of the outer wall 102. Therefore, there is a high possibility of entering the ventilation layer 111. It is possible to prevent intrusion into the ventilation layer 111 by appropriately flowing into the ridge 106.
