JP 2006-169808 A

  FIG. 6B is a diagram illustrating a connection structure in the longitudinal direction of the draining plate in the interstitial trunk difference portion of FIG. 6A. In the conventional connection structure, the two draining plates 103a and 103b are arranged in a state where the respective end portions in the longitudinal direction are overlapped, and are connected by the fixing member 105 to be connected in the longitudinal direction. It was. In FIG. 6B, the fixing members 105 are provided at three locations, and screws are used as the fixing members.

  Here, the following methods are currently used as a method of fixing two plate-like bodies using screws. FIG. 7A and FIG. 7B show a specific mode in the case where the draining plates are overlapped and fixed using screws. FIG. 7A shows a case where the fixing member 105 is fixed using a bolt 1050 and a nut 1051. In this case, a hole 1032 through which the foot 1052 of the bolt 1050 passes is provided in the overlapping portion in the longitudinal direction of the draining plate 103 in advance. Then, two draining plates 103a and 103b are arranged so that the hole 1032 of the draining plate 103 overlaps at the work site, a bolt 1050 is passed through the hole 1032 and provided in advance on the opposite side of the draining plate to the bolt insertion side. The nut 1051 is tightened and fixed. In this case, it is necessary to arrange the nut 1051 on the opposite side of the draining plate 103 from the screw insertion side. This operation significantly reduces the efficiency of the draining plate mounting operation. That is, it is necessary to fix the draining plate 103 to the interstitial trunk difference portion 101 with the nut 1051 disposed in advance on the opposite side of the bolting hole 1032 of the draining plate.

  FIG. 7B shows a state in which two draining plates 103a and 103b are overlapped, a screw hole 1033 to be screwed with the screw 1053 is threaded, and the two draining plates 103a and 103b are fixed by using the screw 1053. It is. In this method, it is not necessary to arrange a nut or the like on the back side of the draining plate, but it is necessary to thread the draining plates 103a and 103b at the work site. Accordingly, variations tend to occur due to the skill of the craftsman. Further, since the two draining plates 103a and 103b are both threaded, the two are fixed as the screwing progresses, but the tightening force does not function so as to press against each other at the contact surface. . Accordingly, there is a problem that a gap is easily formed between the two draining plates 103a and 103b, and water can easily enter the room.

  Therefore, the technical problem to be solved by the present invention is to provide a draining plate connection structure in an interstitial trunk difference portion that is excellent in workability and can ensure sufficient sealing after installation.

  In order to solve the above technical problem, the present invention provides a connection structure for draining plates in an interstitial trunk difference portion having the following configuration.

The present invention is located outside the floor difference between floors, and is a connecting structure of draining plates installed along the floor difference between the floors,
The draining plate is provided with a through hole in the vicinity of the end in the longitudinal direction, and the through holes are arranged so that only the end portions of two adjacent draining plates overlap,
While fixing the two draining plates with a joint member disposed through the two through holes,
The joint member has a rotating shaft asymmetrical locking portion at the distal end of a leg portion that is suspended from a flat plate-like main body portion and has the same thickness dimension as the two draining plates or shorter than the thickness dimension of the two draining plates. Provided is a drainage plate connecting structure, wherein the engaging portion is provided with a bottom surface inclined with respect to the main body portion.

  In the above-described configuration, the draining plate is arranged with its ends overlapped so that the through holes overlap, and is fixed by a joint member that passes through the stacked through holes.

  The joint member has a configuration in which a main body portion and a locking portion are connected by a leg portion. The joint part passes through the through hole of the draining plate and then rotates the leg part as the rotation axis, so that the asymmetrical locking part of the rotating shaft is opposite to the side where the main body part of the draining plate is located. The two draining plates are fixed by engaging with the surface on the side. Here, the rotational axis asymmetrical shape means that when the rotational axis (corresponding to the leg portion of the joint member) is rotated by a predetermined angle, the shape viewed from the rotational axis direction is before and after the rotation. For example, shapes such as an ellipse, a rectangle, and a circle having a rotation axis other than the center can be exemplified.

  In the above configuration, since the bottom surface of the locking portion is inclined with respect to the main body portion, when the locking portion is rotated at the time of fixing, the locking portion is placed on the surface of the draining plate by the inclined portion. Is fixed.

  The said structure WHEREIN: It is preferable that the draining board is provided with the elastic sealing member in the vicinity in which the said through-hole is provided.

  The draining plate is preferably made of a synthetic resin.

  Further, it is preferable that the joint member has a protruding portion formed on the leg forming surface of the main body portion.

  According to the present invention, the two draining plates are fixed by disposing the main body portion and the locking portion of the joint member on both sides of the two draining plates that are overlaid. In addition, the joint member includes a leg portion that is shorter than the thickness of the two draining plates and a latching portion that is provided with an inclined bottom surface. By being arranged on the surface side of the draining plate, it can be fixed by a simple operation.

  Hereinafter, the connection structure of the draining board which concerns on one Embodiment of this invention is demonstrated, referring drawings.

  FIG. 1A is a diagram illustrating a configuration example of an interstitial trunk difference portion using a draining plate connecting structure according to an embodiment of the present invention. The connection structure of the draining board concerning this embodiment is a connection structure to the longitudinal direction of the draining board arrange | positioned between the lining materials 7 in an interstitial trunk difference part.

  The structure of the interstitial trunk difference part is as follows. A panel frame 9 having a U-shaped cross section is fixed to the upper flange 1a and the lower flange 1b of the trunk difference 1 having an H-shaped cross section. The panel frame is fixed by screws 9a. The backing material 7 is fixed to the panel frames 9 on the upper and lower sides of the floor. In the space surrounded by the panel frame and the backing material 7, the heat insulating material 2 is disposed from the indoor side 2a. Examples of the heat insulating material 2 include glass wool.

  Also, long draining plates 3a and 3b are provided between the backing material 7 between the floors, that is, in the portion of the trunk difference 1, extending in the circumferential direction of the outer wall. The backing material 7 and the draining plates 3 a and 3 b are fixed to the panel frame 9 with screws 4.

  An exterior panel 6 is provided outside the backing material 7 on the upper and lower floors. The exterior panel 6 is attached with a gap 8 for heat insulation between the surface of the backing material 7 and the space between the exterior panels 6 is sealed with a sealing member 6a.

  FIG. 1A shows a state in which the ends of two long draining plates 3a and 3b are overlapped. As shown in FIG. 1B, the draining plate is fixed in a state where a plurality of drainage plates are connected along the trunk difference 1. In FIG. 1B, the exterior wall is omitted. Two adjacent draining plates 3a and 3b are arranged so that an overlapping portion 10 is provided at the end. A joint member 5 described later is used to connect the two draining plates 3a and 3b.

  FIG. 2A is a plan view showing a configuration of a draining plate used in FIG. 1A. 2B is a cross-sectional view taken along the line IIB-IIB in FIG. 2A. The draining plate 3 includes a thin plate-like main body 11 having a longitudinal direction in the direction along the trunk difference portion 1. The longitudinal dimension of the main body 11 of the draining plate 3 is usually about 1 to 2 m, and is connected to the backing material 7 by being connected in the longitudinal direction.

  The draining plate 3 is provided with end seal members 12 at both ends in the longitudinal direction. As shown in FIG. 2B, the end seal member 12 is provided on the surface on the side located on the exterior wall 6 side when the draining plate 3 is fixed to the trunk difference portion. A bottom seal member 14 is provided at the lower end of the draining plate. The bottom seal member is provided only on the surface on the side of the backing material 7 when the draining plate 3 is fixed to the trunk difference portion. The bottom seal member 14 prevents water from entering the gap when the draining plate 3 is fixed to the backing material 7. Both the end seal member 12 and the bottom seal member 14 are made of an elastic material.

  Further, three through holes 13 are provided at each end of the draining plate 3. The joint member 5 is inserted into the through hole 13 when two draining plates are connected in the longitudinal direction.

  FIG. 3A is a perspective view of the joint member 5 used for connecting the draining plates shown in FIG. 1A. FIG. 3B is a perspective view seen from another angle of the joint member of FIG. 3A. 3C is a plan view of the joint member of FIG. 3A.

  The joint member 5 is, for example, a synthetic resin member formed by injection molding or the like, and is provided on the leg 23 extending from one surface of the flat plate-like main body 21 and the tip of the leg 23. A locking portion 24 is provided.

  The main body portion 21 is configured by a substantially circular disk and includes a knob 22 on one surface. The knob 22 is used for rotating and fixing the joint member during construction to be described later.

  A leg portion 23 is suspended from a central portion of the surface (leg portion forming surface) 29 on the side where the knob 22 of the main body portion 21 is not provided. Since the leg portion 23 needs to rotate about the Z axis while being inserted into the through hole 13 at the time of construction to be described later, the leg portion 23 is substantially the same as or shorter than the short direction width of the through hole 13 of the draining plate 3. Is preferably a short width. A protrusion 25 is provided on the leg forming surface 29 of the main body 21, and the contact area with the surface of the draining plate 3 is reduced to reduce friction and facilitate the rotation of the joint member 5 during construction, which will be described later. For this reason, the joint member is fitted into the through hole 13 of the draining plate 3 at the time of rotation fixation so that the joint member does not rotate accidentally and falls off.

  A locking portion 24 is provided at the tip of the leg portion 23. As shown in FIG. 3C, the locking portion 24 is configured to be able to pass through the through hole 13 of the draining plate 3. As shown in FIG. 3C, the planar shape of the locking portion is an oval, but is not limited to this, and the shape is not particularly limited as long as it is a rotational axis asymmetrical shape. In this embodiment, as shown in FIG. 3C, when the joint member 5 is rotated about the rotation axis C, the outer shape before and after the rotation angle is rotated is different. Refers to the shape. For example, modifications as shown in FIGS. 5A to 5C are also included.

  In the modification of FIG. 5A, the planar shape of the locking portion 24a is a square. For example, when rotated 45 degrees around the rotation axis C, the outer shapes are different before and after the rotation. In the modification of FIG. 5B, the planar shape of the locking portion 24b is a rectangle having a circular arc on one side. For example, when rotated 90 degrees around the rotation axis C, the outer shape is different before and after the rotation. . In the modified example of FIG. 5C, the planar shape of the locking portion 24c is circular. However, since the rotation center C is deviated from the center of the circle, it is different before and after the rotation by rotating, for example, 180 degrees around the rotation axis C. This is an example of an outer shape.

  The bottom surface 27 of the locking portion 24 is provided to be inclined with respect to the main body portion 21. In the example of FIG. 3A, inclined surfaces 26 are provided in different directions on the X-axis direction side with respect to the leg portion 23. The inclined surface 26 is provided so that the bottom surface of the locking portion 24 can be easily positioned on the surface of the draining plate 3 during construction. As will be described later, the two draining plates 3 are pressed against each other as described later. It is possible to improve the sealing performance between the two.

  As shown in FIG. 3B, the distance B between the bottom surface 27 of the locking portion 24 and the surface 29 of the main body portion 21, that is, the length of the leg portion 23 is the same as the thickness dimension of the two draining plates to be fixed or 2 The distance A from the upper end of the inclined surface 26 to the surface 29 of the main body 21 is smaller than the thickness dimension of the two draining plates to be fixed. It is structured long. 3B has the protruding portion 25, but when the protruding portion is structured to enter the through hole when the joint portion is rotated by 90 °, the distance to the surface 29 of the main body portion 21 as described above. B, that is, the length of the leg portion 23 is configured to be the same as the thickness dimension of the two draining plates to be fixed or slightly shorter than the thickness dimension of the two draining plates. When the joint portion is rotated by 90 ° and the protrusion does not enter the through hole 13, the distance between the bottom surface 27 of the locking portion 24 and the surface of the protrusion 25 is the length of the leg portion 23, and is fixed. The thickness dimension is the same as or shorter than the thickness dimension of the two draining plates. Here, the “thickness dimension of the draining plate” includes the thickness of the end sealing material in the thickness dimension of the draining plate when the end sealing member is provided.

  Next, a construction method for fixing two draining plates using the joint member 5 will be described. FIG. 4A shows a state in which two draining plates 3a and 3b are overlapped so that the through holes 13 overlap. In FIG. 4A, for the sake of understanding, the through holes of the two draining plates 3a and 3b are shown in a slightly shifted state, but it is not always necessary to shift and overlap them. As described above, the end plate member 3a, 3b is provided with the end seal member 12 at the end thereof. When the two end plate members 3a, 3b are overlapped, the end seal member 12 is pressed and deformed. The initial thickness is achieved.

  First, the locking portion 24 of the joint member 5 is inserted into the through hole in which the two draining plates are overlaid. The insertion is preferably performed in the direction in which the distal end 28 of the locking portion 24 is inserted into the through hole 13 from the exterior wall side. As described above, since the length dimension of the leg portion 23 is slightly shorter than the thickness dimension of the two draining plates 3 a and 3 b, the bottom surface 27 of the locking portion 24 is located in the through hole 13. . On the other hand, the upper end 26a of the inclined surface 26 passes through the through hole 13 and is positioned on the back surface 11b side of the draining plate 3b.

  In addition, the protrusion part 25 of a joint part does not enter into the through-hole 13, and is in the state which contacted the surface 12a of the draining board 3a.

  In this state, the joint portion 5 is rotated in the direction in which the inclined surface 26 abuts the edge of the through hole 13 with the knob 22 of the joint portion 5. FIG. 4B shows a state where the joint portion 5 is rotated 90 degrees and the draining plate is fixed by the joint member. In FIG. 4B, the inclined surface abuts on the edge of the through hole 13, and the locking portion 24 moves along the inclined surface 26 so as to ride on the back surface 11b side of the draining plate 3b. As a result, the end seal member 12 is pressed and deformed. Thereby, the watertightness between the two draining plates 3a and 3b and the watertightness between the main body portion 21 of the joint portion 5 and the draining plate 3a on the exterior wall side are enhanced.

  Moreover, since the protrusion part 25 will be in the state which entered the through-hole 13, it prevents that the joint part 5 rotates accidentally.

  As described above, according to the connection structure of the draining plates according to the present embodiment, the draining plates 3a and 3b are arranged so that the end portions of the two draining plates 3a and 3b are overlapped, and are positioned at the overlapping portion. The two draining plates 3a and 3b can be firmly connected and fixed simply by inserting and rotating the exterior surface side joint member 5 into the through-hole 13 to be rotated. Moreover, the sealing member 12 provided on the two draining plates is pressed and deformed by the bottom surface 27 of the locking portion of the joint member 5 and the main body portion 21, and the watertightness between them can be improved.

  Therefore, the construction is extremely simple, it is not necessary to perform operations such as thread cutting at the construction site, and anyone can perform construction of a certain quality regardless of the skill level.

  Moreover, since the draining board does not need threading etc., it does not necessarily need to be comprised with a metal. For example, it can be manufactured using a synthetic resin. By using a synthetic resin, it can be easily manufactured, and the weight can be reduced, so that on-site handling can be simplified.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, you may comprise so that heat insulating materials, such as a hard polyurethane, may be affixed on the back surface of the draining board 3b on the indoor side. In the draining plate connection structure of the present invention, it is only necessary to insert the joint member into the through hole 13 from the exterior surface side and rotate it, so there is no need to arrange a fixing nut or the like on the back side. Accordingly, if there is a space in the through hole 13 that allows the engaging portion of the joint member 5 to pass through and protrude to the back side, even if a heat insulating material is provided on the indoor side surface of the draining plate 3b, There is no particular trouble.

  In the above embodiment, the knob 22 is provided to facilitate the rotation of the joint member 5. However, the present invention is not limited to this. For example, another member may be inserted to facilitate the rotation. The member insertion recess may be provided.
