Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining member capable of easily joining an external structure such as a balcony to an outer wall provided with an exterior finishing material.

[0002]

2. Description of the Related Art Generally, there is known a panel construction method for constructing a structure such as a floor, wall and roof of a house from floor panels, wall panels and roof panels. In the panel construction method, the general structure of the panel is a box-shaped structure in which a face material is adjusted on at least one surface of a rectangular frame body.
The frame body is formed of a core material, and if necessary, core materials other than the frame body are arranged vertically and horizontally inside the frame body. Therefore, when the panels are joined together or the panel and another structure are joined together, it is necessary to join at the core material portion in order to maintain the joining strength.

The wall includes an outer wall having at least one side surface facing the outside of the house and an inner wall having both side surfaces facing the inside of the house. Then, when the outer wall and the inner wall are joined, the end portion of the inner wall is joined to the inner surface of the outer wall. In addition, when joining the panels as described above, it is necessary to join at the core material portion of the panel, and it is necessary to join the core material portion of the outer wall and the core material that constitutes the frame of the inner wall end portion. .

[0004]

By the way, when an external structure such as a veranda or an eave is to be attached to the outside of a wall body (wall panel) forming an outer wall via an exterior material,
Special bolts are required for joining via the exterior material. Further, the external structure needs to be fixed to the core material of the wall panel constituting the outer wall as described above, but other structures such as the inner wall are joined to the core material portion of the outer wall. There is a part where nothing is joined and a part where nothing is joined.

When the inner wall is joined to the core portion of the outer wall, the core material of the outer wall and the core material of the inner wall are joined, and the core materials are arranged in a double state. There is. That is, in the core portion of the outer wall, there are a portion that is thickened by other structures being joined inside and a portion that is not joined and is not thickened as described above. Then, for example, when the core material of the inner wall is bonded to the core material portion of the outer wall, and when the external structure is bonded to the core material portion of the outer wall by bolts, the core material of the outer wall and the core material are bonded. It is necessary to use a long bolt that penetrates both the core material of the inner wall that has been cut. In addition, when connecting an external structure to a portion of the inner surface of the outer wall that is not joined to anything, use a bolt with an appropriate length so that the bolt does not project to the inner surface side of the outer wall. There is a need.

Therefore, when the external structure is joined to the core material portion of the outer wall, the above-mentioned special bolt is used, and when the thickness of the core material portion of the outer wall is different, as described above, It is necessary to prepare different special bolts, and it is necessary to use bolts that correspond to the thickness of the core material of the outer wall, which complicates inventory management and prepares bolts of a length that corresponds to the construction. Otherwise, there is a risk of delaying construction work.

Further, when the outer wall and the external structure are to be joined to each other by the bolt through the exterior material as described above, a hole is made in the exterior material, which may cause a problem in waterproofness. In addition, if it is desired to secure waterproofness at the bolt portion by some method, it will take some effort.

The present invention has been made in view of the above circumstances, and provides a joining member capable of coping with outer walls having different thicknesses when joining an external structure to an outer wall via an exterior material. That is the purpose.

[0009]

According to a first aspect of the present invention, there is provided a joining member comprising a bolt shaft portion having both ends formed as male threads, and a fixing plate provided so as to be substantially orthogonal to the bolt shaft portion. The means for solving the above problem is that the distance from the fixing plate to one end of the bolt shaft portion and the distance to the other end of the bolt shaft portion are different.

According to a second aspect of the present invention, in the joining member, the wall body and the external structure are attached to the outside of the wall body serving as the outer wall of the house through an exterior material mounted at a distance from the wall body. Used when joining, one end of the bolt shaft portion is fastened to the wall body, the other end of the bolt shaft portion is fastened to the external structure in a state of penetrating the exterior material, The side surface on the one end side of the bolt shaft portion of the fixing plate is attached to the outer surface of the wall body, and on the side surface on the opposite side,
An adjusting material for filling the gap between the wall body and the exterior material is provided,
Further, a waterproof layer is formed on at least a side surface of the adjusting material on the side of the exterior material, which is a means for solving the above problems.

According to a third aspect of the present invention, in the joining member, when the bolt shaft portion is fastened to a portion of the wall body serving as the outer wall where another wall is fastened, the fixing plate of the bolt shaft portion is removed. Is fastened to the wall body to be the outer wall, the end side of which is longer, the bolt shaft portion when fastening the bolt shaft portion to a portion of the wall body to be the outer wall is not fastened The means for solving the above-mentioned problem is that the end portion side of which the distance from the fixing plate is shorter is fastened to the wall body serving as the outer wall.

[0012]

According to the structure of the first aspect, when the joining member is used to join the wall body and the external structure via the exterior material, one end of the bolt shank from the fixing plate. Since the distance to the part and the distance from the fixing plate to the other end of the bolt shaft part are different, depending on whether one end side is fastened to the outer wall or the other end side is fastened to the outer wall, It is possible to deal with core portions having different thicknesses.

Further, according to the structure of claim 2,
An adjusting material for filling the gap between the outer wall and the exterior material is attached to the fixing plate, and a waterproof layer is formed on at least the side surface of the adjusting material on the exterior material side. When joined to an external structure, the inner surface around the portion of the exterior material through which the bolt shaft portion penetrates is covered with the waterproof layer, and water can be prevented from entering through the bolt penetration portion.

Further, according to the third aspect of the invention, when the joining member is fastened to a portion of the wall body serving as the outer wall where another wall is joined, the core member of the wall body serving as the outer wall is fastened. Although the core materials of the other walls are joined, the distance from the fixed plate to one end of the bolt shank and the distance from the fixed plate to the other end of the bolt shank as described above. Since it is different, it can be dealt with by fastening the one having a longer distance from the fixing plate of the bolt shaft portion to the outer wall.

When the joining member is fastened to a portion of the wall body serving as the outer wall which is not joined to the other wall, if the distance between the bolt shank and the fixing plate is long, the bolt shank will not move to the outer wall. Although it will be exposed to the inner surface side, as described above, the distance from the fixing plate to one end of the bolt shank and the distance from the fixing plate to the other end of the bolt shank are different,
This can be dealt with by fastening the bolt shaft portion, which has a shorter distance from the fixing plate, to the outer wall.

The balcony 3 having the side wall 3a attached thereto is shown.

As shown in FIG. 1, the joining member 1 of this embodiment includes a bolt shaft portion 4, a fixing plate 5 welded to the bolt shaft portion 4, and a nail for fixing the fixing plate 5 to the outer wall 2. 6 and an adjusting member (illustrated in FIG. 2) into which the bolt shaft portion 4 is fitted and inserted 7
And a washer 8 and a nut 9 for fastening the bolt shaft portion 4 to the outer wall. As shown in FIG. 2, a washer 8 and a nut 9 are also used to fasten an external structure to the bolt shaft portion 4 fixed to the outer wall 2.

The fixing plate 5 is welded to the bolt shaft portion 4 with the bolt shaft portion 4 inserted therein. Also,
The fixing plate 5 is welded at a position displaced from the center of the bolt shaft portion 4, and the distance from the fixing plate 5 to one end of the bolt shaft portion 4 is different from the distance to the other end. Has become. Here, with the fixed plate 5 as a boundary, the shorter portion of the bolt shaft portion 4 is referred to as a short bolt portion 4a, and the longer portion thereof is referred to as a long bolt portion 4b.

Further, the fixing plate 5 is provided with insertion holes 6a for inserting the nails 6 ... The shape of the fixing plate 5 need not be square as shown in FIG. 1, but may be rectangular or circular, for example. The adjusting material 7 is in the shape of a square plate, and waterproof tape (not shown) is adhered to both surfaces of the adjusting material 7 with the adhesive surface facing the outer surface side (the surface other than the adhesive surface is adhered to the adjusting material 7 by the adhesive. Are bonded) to form a waterproof layer and a bonding surface. And the adjusting material 7
For example, as shown in FIG. 2, the bolt shaft portion 4 is inserted and inserted in a state where both sides are bonded between the side surface of the fixed plate 5 on the siding 10 side and the inner surface of the siding 10. It

That is, the thickness obtained by adding the adjusting member 7 and the fixing plate 5 and the distance between the outer wall 2 and the siding 10 are substantially equal. Further, a release paper (not shown) is adhered to the waterproof tape adhesive surface of the adjusting material 7 when not in use, and the adjusting material 7 is attached to the outer wall 2 and the siding 1.
By peeling off the release paper when sandwiching it between 0 and 0, the adhesive surfaces of the waterproof tapes attached to both surfaces of the adjusting material 7 become the fixing plate 5 fixed to the outer wall 2 and the inner surface of the siding 10. It is designed to be glued.

Therefore, the space between the outer wall 2 and the siding 10 and the through hole formed in the siding 10 for the bolt shaft portion 4 are completely separated by the adjusting member 7. Water is prevented from entering between the outer wall 2 and the siding 10 through the through hole. Further, since the adjusting material 7 is in a state of supporting the siding 10 from the back surface side, it is possible to prevent the portion of the siding 10 that the bolt shaft portion 4 penetrates from being damaged when the external structure is attached. You can do it.

Even when the periphery of the bolt shaft portion 4 of the siding 10 is damaged when the external structure is joined to the outer wall 2, this portion has a waterproof tape of the adjusting material 7 adhered to the inside thereof. Therefore, the waterproof performance does not deteriorate, and the waterproof performance between the siding 10 and the outer wall 2 can be ensured.

The shape of the adjusting material 7 is not limited to the square shape, but may be a rectangular shape or a circular shape.
In addition, the through hole of the siding 10 is filled with caulking material in a state where the bolt shaft portion 4 penetrates, and a state in which water from the through hole of the siding 10 is prevented from entering double. Has become.

Here, the above-mentioned joining member 1 is shown in FIGS.
As described above, the outer wall 2 and the siding 10 will be described in order to explain together with the outer wall 2 and the siding (exterior finishing material) 10 to which the joining member 1 is attached. As shown in FIGS. 2 to 4, the outer wall 2 has core members 11 arranged vertically and horizontally (only the vertical core members are shown).
The framework 12 is composed of, and the face materials 13, 13 attached to both surfaces of the framework 12 are used as a basic skeleton.

In this embodiment, the framework 1 is used.
A rectangular wall panel is constructed from 2 and the face materials 13, 13, and a larger wall body is configured by joining a plurality of wall panels to each other, and the outer wall 2 is configured from these wall bodies. Has become. Further, for the outer wall 2, a plate-shaped or columnar member may be used in combination with the wall panel, if necessary, in addition to the wall panel composed of the frame 12 and the face materials 13, 13. In the example, as shown in FIG. 2, the portion to which the joining member 1 is fixed is a columnar adjusting member 14, and two wall panels are joined together with the columnar adjusting member 14 sandwiched therebetween. ing. Further, as shown in FIG. 3, columnar adjusting members 14a are also used at the corners of the outer wall 2.

A moisture-proof waterproof sheet (not shown) is attached to the outer surface of the outer wall 2 so that the outer wall 2 is not affected by dew condensation or the like generated between the outer wall 2 and the siding 10. Has become. The siding 10 constitutes the outermost surface of the house, and a well-known exterior finishing material can be used.

The siding 10 is not directly joined to the outer surface of the outer wall 2, but a plurality of thin plates (furnace) (not shown) are horizontally arranged on the outer surface of the outer wall 2, and the siding is attached to the thin plate. 10 is in a fixed state.

This is because when the siding 10 is joined to the outer wall 2, the face material 1 of the wall panel that simply constitutes the outer wall 2 is used.
If the 3 and the siding 10 are joined together, sufficient joining strength may not be obtained.
1 is joined with a joining member such as a nail, and the siding 10 is joined to the thin plate fixed to the core material 11, thereby fixing the siding 10 and the core material 11 forming the outer wall 2 via the thin plate. This is because I made it possible. Also,
An interior material 15 is provided on the inner surface of the outer wall 2.

In the outer wall 2 shown in FIG. 2, the columnar member 14 is used at the mounting position of the joining member 1 as described above. Further, in the outer wall 2 shown in FIG. 3, the joining member 1 is attached to the columnar member 14a at the corner portion of the outer wall 2. Also, the outer wall 2 shown in FIG.
In, the inner wall 16 is joined to the joint portion of the wall panels forming the outer wall 2, and the core members 11, 11 of the outer wall 2 and the inner wall 1 are joined together.
The joint member 1 is attached to a portion of the core member 6 where the core member 11a is joined.

In the case of the outer wall 2 shown in FIG. 2, the short bolt portion 4a of the bolt shaft portion 5 of the joining member 1 is inserted into the through hole provided in the columnar adjusting member 14 of the outer wall 2. The fixing plate 5 is temporarily fixed to the outer surface side of the outer wall 2 by the nails 6, and the joining member 1 is fastened from the inner surface side of the columnar member 14 by the nut 9. It should be noted that the inner surface of the columnar member 14 has a recess 17 at the mounting position of the joining member 1.
Are formed. In addition, the joining member 1 is fixed to the fixing plate 5 and the nail 6.
Since the rotation of the bolt shaft portion 4 is restrained at the time of fastening with the nut 9 by temporarily fixing the joint member 1 to the outer wall by ..., even if the rotation of the joining member 1 from the outer surface side of the outer wall 2 is not restrained by, for example, a spanner. The nut 9 can be fastened by operating only the inner surface side of the outer wall 2.

The long bolt portion 4a of the joining member 1
Is in a state of penetrating the siding 10 and extending to the outer surface side of the outer wall 2. Here, the side wall portion 3a of the balcony 3 is fastened to the long bolt portion 4a using the nut 9.

In the case of the outer wall 2 shown in FIG. 2, the short bolt portion 4a of the joining member 1 is in a state of being inserted into the outer wall 2. This is because the length of the short bolt portion 4a is the same. This is because the thickness of the outer wall 2 is shorter than that of the outer wall 2, so that the end portion of the short bolt portion 4a does not project to the inner surface side of the outer wall as shown in FIG. Here, when the long bolt portion 4a of the joining member 1 is inserted into the outer wall 2, the end of the bolt shaft portion 4 penetrates the interior material 15 on the inner surface of the outer wall 2 and projects.

In FIG. 2, the long bolt portion 4a projects into the side wall of the balcony, so that no problem occurs even if the long bolt portion 4a is long. Further, the outer wall 2 shown in FIG. 3 has substantially the same configuration as that of FIG. 2 except that the long bolt portion 4 b of the joining material 1 is inserted into the outer wall 2.

In the case of the outer wall 2 shown in FIG. 3, the portion where the outer wall 2 side end of the bolt shank 4 projects is the bolt shank 4.
Since the inside of the outer wall 2 is perpendicular to the inserted outer wall 2, the long bolt portion 4a is inserted into the outer wall without penetrating the interior material, and the long bolt portion 4 is inserted into the outer wall 2. be able to.

Further, although the outer wall 2 side of the bolt shaft portion 4 is in a state of penetrating the columnar adjusting member 14a and the core member 11,
Since the total thickness of the columnar adjusting material 14a and the core material 11 is shorter than the thickness of the outer wall 2, the bolt shaft portion 4 and the outer wall 2 can be fastened even if the short bolt portion 4a is inserted into the outer wall 2. However, since the length of the short bolt portion 4a has little margin for the thickness of the columnar adjusting member 14a and the core member 11, the long bolt portion 4b is inserted into the outer wall 2.

Further, in the case of the outer wall 2 shown in FIG.
Similar to the case, the structure is substantially the same as that of FIG. 2 except that the long bolt portion 4b of the bonding agent 1 is inserted into the outer wall. In the case of the outer wall 2 shown in FIG. 4, since the inner wall 16 is joined to the portion of the outer wall 2 into which the bolt shank 4 is inserted, the bolt shank 4 is formed of the core material 11 and the inner wall 16 of the outer wall 2. It is necessary to penetrate the core material 11. Therefore, even if the short bolt portion 4a is inserted into the outer wall 2, the joining member 1 is not attached to the outer wall 2.
Since it cannot be fastened to the outer wall 2, it is necessary to insert the long bolt portion 4a into the outer wall 2.

Further, since the end portion of the bolt shaft portion 4 on the outer wall 2 side projects into the inner wall 16, there is no problem even if the long bolt portion 4a is somewhat long. In addition, when the joining member 1 is fixed to the outer wall 2, as shown in FIG.
The exterior material 10 of the balcony 3 can be joined to the side wall portion 3a of the balcony 3 by the bolt shaft portion 4, and the exterior material 10 can be easily attached to the outer wall 2 of the balcony 3 as shown in FIG. Can be joined through. The reference numeral 20 in FIGS. 5 and 6 indicates a window.

As described above, according to the joining member 1 of this embodiment, the structure of the outer wall 2 causes the fixing plate 5 to the bolt shaft portion 4 to be removed.
Whether the distance to the end of the outer wall 2 is required to be shorter than the thickness of the outer wall 2 or longer than the thickness of the outer wall 2, one joint member 1 can be used. Therefore, it is possible to reduce the number of types of the joining member 1 depending on the size, and it is possible to achieve labor saving in inventory management and efficiency in construction.

Further, even if the outer wall 2 and the siding 10 are spaced from each other by attaching the adjusting material 7 having the waterproof layer and the adhesive surface to the joining member 1, the outer wall and the external structure are siding. In the case of joining with the bolts via the bolts 10, a structure capable of preventing water from entering through the through holes of the bolts of the siding 10 can be provided without any trouble.

Although the balcony 3 is used as the external structure in the above embodiment, the external structure that can be joined to the external wall 2 is not limited to the balcony, and can be used as a front door, a shutter facility for windows, or the like. It is possible to join various things such as the installation stand of the outdoor unit of the air conditioner.

[0042]

As described above in detail, according to the joining member of the first aspect of the present invention, the joining member is used for joining the outer wall and the external structure through the exterior material. In this case, since the distance from the fixing plate to one end of the bolt shank and the distance from the fixing plate to the other end of the bolt shank are different, fasten one end to the outer wall or Depending on whether the end side is fastened to the outer wall, a single joining member can deal with different structures of the outer wall. Therefore, it is possible to achieve labor saving in inventory management of joint members and efficiency in construction.

According to the joining member of the second aspect, an adjusting material for filling the gap between the outer wall and the exterior material is attached to the fixing plate, and at least a side surface of the adjusting material on the exterior material side. Since the waterproof layer is formed, when the outer wall and external structure are joined using this joining member, the inner surface around the portion where the bolt shank of the exterior material penetrates is covered with the waterproof layer. It is possible to prevent water from entering through the bolt penetration portion. That is, the through-hole portion of the exterior material can have a waterproof structure only by installing the adjusting material.

According to the third aspect of the present invention, when the outer wall and the external structure are joined by the joining member, the longer part of the bolt shank of the joining member is fastened to the outer wall. , Depending on whether the shorter part is fastened to the outer wall, it is used both when the outer wall and the inner wall are to be joined to the outer wall core part to which the outer structure is to be joined, and when they are not joined. can do. That is, when another wall is joined to the inner surface side of the core material of the outer wall to be joined to the external structure, the core material of the other wall is overlaid on the core material of the outer wall. , Long bolts that penetrate both of these cores are required. On the other hand, if nothing is joined to the core material of the outer wall, only the core material of the outer wall needs to be penetrated, and a short bolt so that it does not penetrate the outer wall and project inward from the interior material. Is required.

Therefore, as described above, by using the short side and the long side with the fixing plate of the bolt shaft portion of the joining member as a boundary, one type of joining member can cope with the above two cases. Therefore, it is possible to reduce the size of the joining members, save labor in inventory management, and reduce costs by sharing the members.
