Description

  The present invention relates to a draining material used for a base of a building and a draining material construction method, and more particularly to a draining material having a function for ventilation under a floor or a wall and a draining material construction method.

  Conventionally, as a draining material used for the foundation of a building, a draining material having a function for ventilation under the floor or in a wall is known. Various types of drainage materials have been proposed. For example, a draining material provided with a vent is known (for example, Patent Documents 1 and 2). By providing a vent hole in the draining material in this way, ventilation under the floor or in the wall is enabled.

  By the way, a generally well-known draining material is a type of draining material in which only a single protruding portion is formed to guide rainwater to the outside of a building, that is, a one-stage type draining material. For this reason, when viewed from the outside, there is a problem that there is no volume of the protruding portion and a poor impression is given.

  Further, a sash may be arranged above the drainage material in the building, but the design of the building is various, and the interval between the sash and the drainage differs depending on the type of sash used. In the case of a conventional single-stage drainer, if there is a wide space between the sash and the drainer, an appropriate width is provided between the sash and the drainer to improve the appearance of the building. It was cumbersome to have to install the processed exterior material.

  Therefore, a draining material in which two protruding portions are formed in the vertical direction to guide rainwater to the outside of the building, that is, a two-stage draining material has been proposed (for example, Patent Document 3). Thus, since the draining material is formed in two stages, the draining material can have a volume, a sash or the like is provided above the draining material, and a wide space is provided between the sash and the draining material. Even if it is possible, it is not necessary to install an exterior material between the sash and the drainage material, and an excellent drainage material can be provided in terms of design.

JP 2003-119912 A (page 2-3, FIGS. 1 to 4) JP 2002-61306 A (page 3, FIGS. 1 and 2) Japanese Patent Laying-Open No. 2004-27828 (page 7-8, FIGS. 14 and 15)

  On the other hand, depending on the type of sash used, the interval between the sash and the draining material may be narrow. In such a case, when using a two-stage drainer as in the technique of Patent Document 3 above, in order to avoid a collision between the sash and the drainer, the drainer is located at the lower part of the sash. It was necessary to perform processing such as cutting the upper part of the material.

  In particular, in the case of a two-stage draining material such as the technique of Patent Document 3, the design is excellent, but the shape is complicated because it is two stages, and only the upper stage of the draining material is cut off. Processing required skill and could not be easily performed at the construction site.

  In view of the above problems, the object of the present invention is to allow easy processing at a construction site corresponding to the distance between the sash and the draining material, which varies depending on the shape of the sash and the design of the building. The object is to provide a two-stage draining material and a draining material construction method with less labor.

  In order to solve the above-described problem, the draining material according to claim 1 is a draining material (J, L) installed above a fabric foundation of a building, the upper draining material (Ja, La), and the upper part A lower drainage material (Jb, Lb) located below the drainage material, wherein the upper drainage material (Ja, La) is formed of a bent plate material and is disposed along the vertical trunk edge of the building. A first abutting surface portion (Ja1, La1) and a first extending surface portion (Ja2, La2) formed at the tip of the first abutting surface portion (Ja1, La1) bent at an obtuse angle to the outside of the building; The first finding surface portion (Ja3, La3) formed at the tip of the first extending surface portion (Ja2, La2) bent downward from the outdoor side, and bent from the first finding surface portion (Ja3, La3) to the indoor side The second extension surface portion (Ja4, La4) formed at the tip, and the second extension A second abutting surface portion (Ja5, La5) formed on the indoor side of the surface portion (Ja4, La4) and disposed along the vertical trunk edge of the building, the lower draining material (Jb, Lb), A third abutting surface portion (Jb1, Lb1) that is formed of a bent plate material and is disposed along the vertical trunk edge of the building, and an obtuse angle from the third abutting surface portion (Jb1, Lb1) to the outside of the building. A third extension surface portion (Jb2, Lb2) formed at the tip of the second extension surface portion and a second finding surface portion (Jb3) formed at the tip of the third extension surface portion (Jb2, Lb2) bent downward from the outdoor side. , Lb3) and a fourth extending surface portion (Jb45, La45) formed at the end bent from the second finding surface portion (Jb3, Lb3) to the indoor side, and the lower drainage material is the upper drainage material The second extending surface portion (Ja4, L 4) and the fourth extending surface portion (Jb45, La45) each vent (Ja4a, Jb5a), characterized in that has been formed.

  Thus, since the upper drainage material and the lower drainage material are comprised by another member, the usage which does not use an upper drainage material or a lower drainage material according to a condition is attained. Moreover, because the vents are formed in each of the upper drainage material and the lower drainage material, even if a part that does not use either the upper drainage material or the lower drainage material occurs in a part of the building, it is provided in the other The ventilation hole can sufficiently vent the floor or inside the wall, so that the ventilation is not greatly hindered. Furthermore, even when processing such as cutting the draining material occurs, processing is easy because the upper draining material and the lower draining material can be handled in a separated state.

  In addition, as in the draining material according to claim 2, in the draining material according to claim 1, a joining portion for joining the upper draining material and the lower draining material to the upper draining material and the lower draining material. (Engagement protrusion La5b, Lb2a, contact protrusion La5c, presser protrusion Lb1b) is preferably formed.

  As described above, since the joint portion is formed on the upper drainage material and the lower drainage material, an upper drainage material and a lower drainage material are not required without separately requiring a member for joining the upper drainage material and the lower drainage material. Can be easily performed, and it is easy to install a two-stage drainer composed of an upper drainer and a lower drainer.

  Further, as in the draining material according to claim 3, in the draining material according to claim 2, the joint portion is a first engaging portion (engagement) formed on the second contact surface portion (La5). It is preferable that it is configured to include a joint protrusion La5b) and a second engagement portion (engagement protrusion Lb2a) that is formed in the lower draining material and engages with the first engagement portion. is there.

  With this configuration, the upper drainage material and the lower drainage material can be easily joined by engaging the first engagement portion and the second engagement portion, and the upper drainage material and the lower drainage material are joined. The installation of the two-stage draining material thus made becomes simple.

  Further, as in the draining material according to claim 4, in the draining material according to claim 2 or 3, the joining portion is a contact protrusion formed on the second contact surface portion (La5). (La5c) and a presser protrusion (Lb1b) formed on the third contact surface portion (Lb1) and positioned above the contact protrusion are preferable.

  As described above, the presser protrusion is positioned above the contact protrusion, so that the joining of the upper drainage material and the lower drainage material is difficult to be released.

Moreover, in the draining material according to any one of claims 1 to 4, like the draining material according to claim 5, the lower draining material is provided on the third contact surface portion (Jb1, Lb1). A fixing hole (nail hole Lb1a) for fixing the fixing hole is formed, and a fixing hole covering part (La5a) for covering the fixing hole from the outdoor side of the building is provided on the second contact surface part (Ja5, La5). It is preferable that
As described above, the appearance of the building is improved by providing the fixing hole covering portion.

  In order to solve the above-mentioned problem, the draining material construction method according to claim 6 is a draining material construction method in which the draining material according to claim 1 is installed above the fabric foundation, It comprises a step of fixing the lower draining material to a vertical body edge installed in the upper part and a step of joining the upper draining material to the lower draining material.

  Thus, according to the draining material construction method according to claim 6, the upper draining material and the lower draining material are joined, and the two-stage draining material composed of the upper draining material and the lower draining material is obtained. It can be installed above the fabric foundation.

  Further, in the draining material construction method according to claim 6, in the draining material construction method according to claim 7, in the step of joining the upper draining material to the lower draining material, It is preferable that the formed first engaging portion (engaging protrusion La5b) is engaged with the second engaging portion (engaging protrusion Lb2a) formed on the lower draining material.

  In this way, by engaging the first engagement portion formed on the upper drainage material with the second engagement portion formed on the lower drainage material, the upper drainage material and the lower drainage material are joined. The upper drainage material and the lower drainage material can be easily joined without requiring a separate member, and the installation of a two-stage drainage material composed of the upper drainage material and the lower drainage material becomes simple.

  Further, in the draining material construction method according to claim 7, in the draining material construction method according to claim 8, in the step of joining the upper draining material to the lower draining material, the second abutment is performed. It is preferable that the contact protrusion (La5c) formed on the surface portion (La5) is positioned below the presser protrusion (Lb1b) formed on the third contact surface portion (Lb1).

  Thus, by positioning the contact protrusion formed on the second contact surface portion below the press protrusion formed on the third contact surface portion, the press protrusion above the contact protrusion. Is located and the upper drainage material and the lower drainage material are not easily disconnected.

  Moreover, in the construction method of the draining material as described in any one of Claims 6 thru | or 8, like the construction method of the draining material of Claim 9, the said upper draining material and the said lower draining material In the joining step, a fixing hole (nail hole Lb1a) formed in the third contact surface portion (Jb1, Lb1) for fixing the lower draining material is formed in the second contact surface portion (Ja5, La5). It is preferable to cover with the formed fixing hole covering portion (La5a).

  Thus, by covering the fixing hole with the fixing hole covering portion, it becomes possible to install the draining material so that the appearance of the building is improved.

  Moreover, in the construction method of the draining material as described in any one of Claims 6 thru | or 9, like the construction method of the draining material of Claim 10, the said upper draining material and the said lower draining material Before the joining step, a part of the upper drainage material is cut at any part from the first contact surface portion (Ja1, La1) to the first finding surface portion (Ja3, La3), and the upper drainage material In the step of joining the lower draining material to the lower draining material, it is preferable to join the portion including the second extended surface portion (Ja4, La4) of the cut upper draining material to the lower draining material.

  Thus, in the process of cutting a part of the upper drainage material at any part from the first contact surface portion to the first finding surface portion and joining the upper drainage material with the lower drainage material, Among them, even when a structure such as a sash is located above the draining material by joining the portion including the second extending surface part and the second contact surface part with the lower draining material, the gap between the sash and the draining material is maintained. In addition, it becomes possible to easily install the draining material.

  As described above, according to the draining material of the present invention, even when a sash or the like is provided above the draining material, the upper draining material and the lower draining material are configured as separate members. Depending on the interval, it is possible to use such that no upper drainage material or lower drainage material is used. In addition, since vent holes are formed in each of the upper drainage material and the lower drainage material, a ventilation area is ensured even when a part where either the upper drainage material or the lower drainage material is not used is generated in a part of the building. In this case, the ventilation under the floor and the wall can be sufficiently performed by the ventilation hole provided on the other side, so that the ventilation is not greatly hindered. In addition, the upper drainage material and the lower drainage material are not integrated, but are configured as separate members, so that even when processing such as cutting the drainage material occurs, the upper drainage material and the lower drainage material are separated. Since it can be processed in a state that has been done, processing at the construction site is easy.

  Moreover, according to the construction method of the drainage material of this invention, an upper drainage material and a lower drainage material are joined, and the two-stage drainage material comprised from an upper drainage material and a lower drainage material is set above a cloth foundation. It becomes possible to install.

  In the present embodiment, the first contact surface portion Ja1 is formed with a folded portion Ja1b whose end is folded, and the bottom surface portion Jb5 is formed with a folded portion Jb5b. By forming the folded portion Ja1b and the folded portion Jb5b, the rigidity of the draining material J is increased.

Next, the procedure for installing the draining material J will be described.
First, the base packing B is installed on the upper surface A1 of the fabric foundation A. A base C is installed on the upper surface B1 of the base packing B. The indoor wall E is nailed to the side surfaces of the base C and the floor material D. The heat insulating material frame F is nailed to the indoor wall E.

  Subsequently, the heat insulating material G is filled in a portion surrounded by the heat insulating material frame F and covered with a moisture permeable waterproof sheet H from the outdoor side. Further, the vertical trunk edge I is nailed to the thermal insulation frame F with the moisture permeable waterproof sheet H sandwiched between the vertical trunk edge I and the thermal insulation frame F.

  Subsequently, the lower draining material Jb is placed on the upper surface A1 of the fabric foundation A, and the lower draining material Jb is fixed to the vertical trunk edge I by passing the nail through the nail hole Jb1a. Further, the nail is passed through the nail hole Ja1a and the upper draining material Ja is fixed to the vertical trunk edge I by nail. At this time, the second contact surface portion Ja5 of the upper drainage material Ja and the third contact surface portion Jb1 of the lower drainage material Jb are overlapped to make the joint hole Ja5a and the joint hole Jb1b communicate with each other.

  Then, the upper drainage material Ja and the lower drainage material Jb are joined to the joining hole Ja5a and the joining hole Jb1b through wood screws or nails. A space for inserting a wood screw or the like into the joint hole Jb1b of the third contact surface portion Jb1 is secured between the second extension surface portion Ja4 and the third extension surface portion Jb2.

  Thus, after fixing the draining material J, the outer wall surface material K is made into the vertical trunk edge I in the state which pinched | interposed the 1st contact surface part Ja1 of the upper draining material Ja between the outer wall surface material K and the vertical trunk edge I. Fix it.

  According to the above structure, the draining material J which can ventilate under a floor or a wall can be installed easily. The air outside the building passes through the air holes Ja4a and Jb5a, passes through the space B0 between the base packings B installed at a predetermined interval on the fabric foundation A, and ventilates under the floor. Moreover, the air outside the building that has passed through the vent hole Ja4a and the vent hole Jb5a passes through the space I0 between the vertical trunk edges I that are installed at a predetermined interval, and ventilation in the walls is performed.

  Moreover, since the draining material J of this embodiment is configured to join the upper draining material Ja and the lower draining material Jb by passing wood screws, nails, etc. through the joining holes Ja5a, Jb1b, the upper draining material Ja and the lower draining material Ja The draining material Jb can be easily combined, and a two-stage draining material can be easily installed. Furthermore, since the upper drainage material Ja and the lower drainage material Jb are comprised by another member, the usage which does not use the upper drainage material Ja or the lower drainage material Jb according to a condition is implement | achieved easily. For example, in a situation where the distance between the lower end of another structure such as a sash installed above the drainage material J and the drainage material J is narrow, the upper drainage material Ja is located below the other structure such as the sash. It is possible to use without using.

  4 and 5 are explanatory views showing an example of use of the draining material J when the sash S is provided above the draining material. As shown in FIGS. 4 and 5, when the distance between the lower end of the sash S and the fabric foundation A is short and the interval between the draining material J and the sash S cannot be secured, the upper draining is performed at the portion corresponding to the sash S. What is necessary is just not to use Ja.

  In a conventional two-stage draining material, that is, an integrated two-stage draining material in which a portion corresponding to the upper draining material Ja and a portion corresponding to the lower draining material Jb are integrated, the upper portion of the draining material J If the gap between the lower end of other structures such as sashes installed on the sash and the draining material J cannot be secured, processing such as cutting the top of the draining material is necessary, and the two-stage type having a complicated shape It was troublesome to cut out only a part of the draining material. On the other hand, in this embodiment, since the upper drainage material Ja and the lower drainage material Jb are comprised by another member, the usage which does not use the upper drainage material Ja according to a condition is implement | achieved easily.

  In this embodiment, the upper drainage material Ja is provided with a vent hole Ja4a, and the lower drainage material Jb is provided with a vent hole Jb5a. Therefore, as illustrated in FIG. Even if there is a place where either one of the draining material Ja or the lower draining material Jb is not used, if the ventilation area is secured, the ventilation hole provided on the other side can sufficiently ventilate the floor or the wall. As a result, ventilation is not greatly hindered.

  Further, as in the example of FIG. 5, when only the lower drainage material Jb is used and the third contact surface portion Jb1 collides with the sash S, the lower drainage material Jb is cut at the third contact surface portion Jb1. Then, the cut upper draining material Jb ′ is used.

  That is, in the example of FIG. 5, the lower drainage material Jb is disposed at the third contact surface portion Jb1 in accordance with the distance between the fourth extending surface portion Jb4 (the upper end of the fabric foundation A) of the lower drainage material Jb and the lower end of the sash S. Cut (FIG. 5A). Then, the cut lower drainage material Jb ′ is installed on the upper part of the fabric foundation A, and the gap formed between the cut lower drainage material Jb ′ and the sash S is filled with a synthetic resin sealing material (FIG. 5B). ).

  Thus, in this embodiment, since the upper drainage material Ja and the lower drainage material Jb are not integrated and are comprised by another member, as shown in the example of FIG. Even when processing is necessary, the upper drainage material Ja and the lower drainage material Jb can be handled in a separated state, and therefore processing is easy.

  In addition to the examples of FIGS. 4 and 5, as shown in the examples of FIGS. 6 to 8, the distance between the sash and the draining material may vary depending on the type of sash used for the building. This change can be accommodated by cutting a part of the upper drainage material Ja or the lower drainage material Jb according to the type. Moreover, even when such processing is performed, the partial drainage material Ja and the lower drainage material Jb are not integrated but are formed as separate members, so that the upper drainage material Ja and the lower drainage material Jb are handled in a separated state. Therefore, processing at the construction site is easy.

As shown in the example of FIG. 6, depending on the type of sash, the distance between the lower drainage material Jb and the sash _Sx is too wide only by using the lower drainage material Jb. Ja1 Although sometimes get in the way on the positional relationship between the sash S _x, in this case, the upper draining member Ja is cut by the first contact face portion Ja1, upper draining material after cutting Ja _x ( The portion including the second extending surface portion Ja4) is used.

In the example of FIG. 6, in accordance with the distance between the second extending surface Ja4 upper draining member Ja and (the upper end of the fabric foundation A) and the lower end of the sash S _x, cut an upper draining member Ja in the first contact face portion Ja1 (FIG. 6A).
