Description

  The present invention relates to a drainage member disposed on a joint around a window frame, and a joint material with a drainage member. Specifically, the present invention relates to a drainage member that is disposed on a joint and has excellent workability, durability, and appearance, and a joint material with a drainage member.

  A joint which is a gap between the window frame and the outer wall material is formed around a window such as a sash disposed in the building. Then, the joint material is filled in the joint to prevent or suppress rainwater or the like from entering the inside of the building from here. On the other hand, although the infiltration of rainwater from the joints is prevented by the joint material, there are not a few cases where rainwater entering from other parts and reaching the back surface (inner side) of the outer wall material or water due to condensation is present. In a normal outer wall portion, the water is drained by flowing down the building along the back surface of the outer wall material. However, due to the presence of the window frame, the water cannot flow down below this, and water will accumulate in this state, causing a problem.

  Therefore, means for draining the water is provided between the window frame and the outer wall material, particularly at the joint between the upper window frame and the outer wall material. Patent Document 1 discloses a water draining member that can be used as a sealing material, that is, a wet joint material as a joint material. According to this, a molded body (drainage member) having a drainage hole penetrating the interior and exterior of the joint is fixed to the joint material with double-sided tape or the like, and a sealant is filled around the joint to fill the joint and to form the molded body. It is fixed by the adhesive force of the sealing.

Further, a so-called dry type joint material in which a long and predetermined elastic member is pushed into the joint to fill the joint is not disclosed in the literature, but for example, a part thereof is notched so as to penetrate in the indoor and outdoor directions. A technique for forming a drainage portion is known.
Japanese Patent No. 3799494

  However, the drainage member as disclosed in Patent Document 1 is based on a wet joint material, and is fixed using the adhesive force when the joint material is dry. Therefore, it cannot be used as a dry joint material. For example, if it is left in the joint only by the adhesive force of adhesive or double-sided tape, it is a problem in durability from the viewpoint that it is a member for drainage. was there.

  Moreover, in the conventional method used for the dry joint material which forms a drainage part by notching, there is a problem that the notch has to be produced every time it is constructed, and it takes time and effort in the construction. Moreover, since the hole is formed by notching, it is not preferable in appearance.

  Then, this invention makes it a subject to provide the drainage member arrange | positioned in a joint and excellent in workability, durability, and external appearance, and the joint material with a drainage member.

  The sidings 2, 2,... Are plate-like members having a predetermined size, and are juxtaposed in the vertical and horizontal directions as the outer wall of the building 1. Therefore, the sidings 2, 2,... Have a great decorative significance of the building 1, and one side thereof is a design surface and is provided with patterns and irregularities. These sidings 2, 2,... Are fixed to the building 1 directly on the frame 4, 4, or the trunk edge 5 of the building 1 or via a fixture. In the building 1 provided with the water draining member 10 of the present invention, siding used in a normal building can be used, and is not particularly limited.

  The window 3 is a so-called sliding window. Specifically, the window 3 has a frame formed by combining an upper horizontal frame 3a, vertical frames 3b, 3b provided along the opening of the building 1 and a lower horizontal frame (not shown) in a frame shape. is doing. The sliding shoji 3c and 3d are arranged inside the frame so as to be movable in the direction of finding. In the building 1 provided with the water draining member 10 of the present invention, a window used in a normal building can be used, and is not particularly limited. For example, a window that opens and closes in a swing manner is not limited to a sliding window.

  A gap is formed between the frame of the window 3 and the sidings 2, 2,. The drainage members 10 and 10 of the present invention are disposed at the joint. The draining members 10, 10 are provided between the upper horizontal frame 3 a and the siding 2 in particular.

  The frame 4 is a structural member of the building 1 and is a so-called column or beam. The body edge 5 is a plurality of bars arranged in parallel to the outside of the columns and beams so as to pass between the columns and the beams as the frame 4, and between the frame 4 and the sidings 2, 2,. Ventilation can be ensured and the mounting strength of the sidings 2, 2, ... can be improved. As the frame 4 and the trunk edge 5, those used in ordinary buildings can be used.

  The pedestal 6 is a member having a rectangular cross section that is attached to the housing 4 at the back of the joint. The pedestal 6 is fixed by bonding the joint material 20 to the outdoor side surface thereof. As a result, the position of the joint material 20 in the indoor / outdoor direction is determined. The shape of the pedestal is not particularly limited as long as the above object can be achieved.

  Next, the water draining member 10 will be described. FIG. 3 is a perspective view of the drainage member 10 and the joint material 20. Here, the joint material 20 is not shown in the length direction (upper left and lower right in the drawing) and is shown short. 4A and 4B are views showing the water draining member 10. FIG. 4A is a front view, FIG. 4B is a rear view, FIG. 4C is a side view, and FIG. 4D is FIG. It is arrow sectional drawing along the line shown by BB in FIG. For convenience of explanation here, in the water draining member 10, the horizontal direction in FIG. 4 (a) is the length direction, the vertical direction is the height direction, and the back / front direction is the thickness direction. FIG. 5 is a cross section of the joint material 20 (cross section orthogonal to the longitudinal direction). FIG. 5A shows a scene where the elastic bodies 23, 23 are allowed to expand to fill the joint, and FIG. 5B shows an elastic body 23 before the joint material 20, 20 is inserted into the joint, for example, during distribution. , 23 shows a scene in which the expansion is prohibited. FIG. 6 is a perspective view when the draining member 10 and the joint materials 20 and 20 are combined. The water draining member 10 and the joint material 20 will be described with reference to FIGS.

  As shown in FIGS. 3 and 4, the water draining member 10 includes a box 11 and convex portions 15 and 15 which are connecting portions. The box body 11 is a hollow box-shaped body in which a total of six flat plates of three sets facing each other are combined. Here, the height of the box 11 is formed to be substantially the same as or slightly smaller than the groove width of the joint. The thickness of the box 11 is thinner than the sidings 2, 2,.

  A pair of opposing flat plates that form the length and height of the box 11 is provided with slits 12, 12,... And slits 13, 13,. The slits 12, 12,..., 13, 13,... Have a rectangular shape that is long in the height direction of the water draining member 10 and short in the length direction of the water draining member 10. .. Are provided on one flat plate, and five slits 13, 13,... Are provided on the other flat plate facing the one flat plate.

  4 (d), the slits 12, 12,... And the slits 13, 13,... Are viewed from the front (FIG. 4 (a)), while the slits 13, 13,. In FIG. 4B, the slits 12, 12,... Are arranged in a staggered manner so as not to be seen. Thereby, when the draining member 10 is installed at the joint, the interior and the exterior do not communicate directly in a straight line, and at least one flat plate exists as a wall. Therefore, it is possible to attenuate wind and rain from the outdoor side and prevent wind and rain from blowing into the room through the slit while maintaining the wind and rain.

  From each of a pair of flat plate arrange | positioned at the left and right of the box 11, the plate-shaped convex parts 15 and 15 are provided toward the left-right direction outer side further. The convex portions 15 and 15 are formed to be slightly smaller in size in the height direction and the thickness direction than the box body 11.

  As can be seen from FIGS. 3 and 5, the joint material 20 includes a core material 21, a decorative material 22, elastic bodies 23 and 23, and an adhesive material 24. Further, when the expansion of the elastic bodies 23, 23 is prohibited, for example, during distribution before the joint material 20 is inserted into the joint, as shown in FIG. 5 (b), encapsulating plates 26, 26 are further provided. ing.

  The core material 21 is a long rod-shaped member having a substantially H-shaped cross section. Both ends of the H-shaped parallel opposing pieces are formed so as to be bent small so as to face each other.

The decoration material 22 has a substantially C-shaped cross section, and is a long member formed of a soft and easily deformable material. One of the opposing H-shaped pieces of the core material 21 is inserted into and attached to the C-shaped opening. Therefore, an annular portion 25 as a recessed portion that is a connected portion is formed by the decorative material 22 and the core material 21. As will be described later, the convex portion 15 of the drainage member 10 is inserted inside the annular portion 25 to form the joint material with the drainage member of the present invention, and the drainage member 10 is appropriately fixed within the joint. .
The decorative material 22 is inserted into the joint with the decorative material 22 facing the outdoor side. Therefore, colors and patterns having excellent design properties are given in consideration of the influence on the appearance. Moreover, since the decoration material 22 is formed of a soft and highly flexible material as described above, it can be in close contact with the inner surface of the joint when inserted into the joint, thereby improving waterproofness. .

  The elastic bodies 23, 23 are arranged so as to be inserted into each of the H-shaped open portions of the core member 21, and are fixed to the central piece by a method such as adhesion. Further, the elastic bodies 23, 23 are formed of, for example, a sponge-like material, can be easily expanded and contracted, and can appropriately spread in the joint. This prohibits movement of air and water through the joint. The elastic body 23 is compressed and enclosed by the enclosing plates 26 and 26 as shown in FIG. 5B until just before being inserted into the joint at the time of distribution or construction, for example. Thereby, the elastic bodies 23 and 23 can be made small before being inserted into the joint, and handling becomes easy. Here, it is preferable that the elastic bodies 23 and 23 are materials that take a predetermined time from the posture in which the compression is maintained until the compression force is removed and the elastic bodies 23 and 23 extend. Thereby, even after removing the encapsulating plates 26, 26, the elastic bodies 23, 23 can be inserted into the joints in a time until they extend, so that the construction becomes easy.

  The adhesive material 24 has adhesiveness that is disposed on the outer side of a piece on the opposite side to the side on which the decorative material 22 is attached in the H-shaped cross section of the core material 21. An example of this is a double-sided tape. The joint material 20 and the pedestal 6 described above are fixed by the adhesive material 24.

  The drainage member 10 and the joint materials 20 and 20 having such a configuration are combined as shown in FIG. 6 to form the joint material with the drainage member of the present invention. That is, the projections 15 and 15 as the connecting portions of the drainage member 10 are attached so as to be inserted into the annular portions 25 and 25 as the connected portions of the joint materials 20 and 20, respectively. At this time, the drainage member 10 is arranged so that the height direction and the two elastic members 23, 23 of the joint material 20 are in the vertical direction. The draining member 10 and joint material 20, 20 combined in this way are inserted into the joint formed between the upper window frame 3 a and the siding 2 as shown in FIGS. 1 and 2. At that time, the surface of the drainage member 10 provided with the slits 12, 12,... And the decorative material 22 of the joint material 20 are directed to the outdoor side. At this time, it is preferable that the flat outdoor side surface in which the slits 12, 12,... Are arranged and the outdoor side surface of the decorative material 22 are substantially flush. As a result, the design is improved and the unevenness is reduced to facilitate cleaning.

Accordingly, the indoor and outdoor directions communicate with each other at the joint of the drainage member 10 through the slits 12, 12,... And the slits 13, 13,. Moreover, since the slits 12, 12,... And the slits 13, 13,... Are arranged in a staggered manner as described above, the momentum of blowing from the outdoor side can be weakened.
Here, a mesh may be inserted inside the box 11 for the purpose of further weakening the momentum of blowing.

Since the water draining member 10 can be fixed to the joint material by inserting it into the joint material 20, the water draining member can be fixed stably without relying on its adhesive strength or adhesive material like a wet joint material. can do. However, this does not prevent the use of the adhesive material to temporarily fix the water draining member 10 to the joint material 20, and the adhesive material is provided on a part of the convex portion 15, and the annular portion 25 of the decorative material 22. You may make it stick to the side.
On the other hand, there is no need to cut out a part of the joint material in order to form a drainage portion in the indoor / outdoor direction like a conventional dry joint material, which is highly convenient.

  Moreover, since it is not necessary to arrange | position and construct the draining member 10 and the joint materials 20 and 20 separately on a joint, since it can construct simultaneously, workability | operativity improves.
