Description

  The present invention relates to a water-stop structure for a window frame that is effective in preventing peeling of a water-stop agent applied to a joint.

  When a water-stopping agent such as silicon is applied to the joint portion of the window frame formed by joining the left and right vertical frame members and the upper and lower horizontal frame members with a joining member, the frame portion is stopped to the hollow portion. Since the liquid agent flows in and is consumed wastefully, in order to eliminate the waste of the water-stopping agent, it is known that the hollow portion of the frame member is closed with a closing plate so that the water-stopping agent does not flow into the hollow portion. . (For example, see Patent Document 1)

JP 2009-161992 A

  However, if the hollow portion of the frame material is closed with a closing plate as described above so that no gap is formed in the joint portion, the water-stopping agent such as silicon only forms a thin layer at the joint portion, and is adhesive. Since the water-stopping agent which is poor in water has insufficient holding power, it tends to cause peeling, and there has been a demand in the industry for the emergence of measures that can prevent this peeling.

  The present invention solves the above problems, and forms a gap at the joint between the vertical frame member and the horizontal frame member with a spacer interposed therebetween, and allows the water-stopping agent to flow into this gap, thereby increasing the holding power of the water-stopping agent. The task is to prevent the peeling by increasing the thickness.

  In order to solve the above-described problems, the water stop structure for a window frame according to the present invention employs the following configuration.

According to the first aspect of the present invention, the left and right vertical frame members and the upper and lower horizontal frame members are formed by bonding with a bonding member so that the edge of one frame member is in contact with the side surface end of the other frame member. In the window frame, a plurality of thin plate-like spacers formed narrower than the thickness of the frame material between the edge of the one frame material and the side surface edge of the other frame material are separated. When the water-stopping agent is applied to the joints of the window frame to the gaps, a part of the water-stopping agent flows into the gaps. I tried to make it.

In the invention according to claim 2, when the left and right vertical frame members and the upper and lower horizontal frame members forming the window frame have a hollow structure, the spacer is engaged with the hollow portion of the frame member, and the spacer is inserted into the gap. A positioning member is attached to hold it at a position suitable for formation.

In the invention according to claim 3, when the left and right vertical frame members forming the window frame and the upper and lower horizontal frame members have a foam structure, the spacer engages with a hole or a groove formed in the frame member, A positioning member for holding the spacer at a position suitable for forming the gap is attached.

Advantages of the Invention According to Claim 1 When a window frame is formed by joining a vertical frame member and a horizontal frame member with a bonding material, a thin width that is slightly narrower than the thickness of the frame member is formed at the joint portion of both frame members. If the plate-like spacers are sandwiched so as to be separated, gaps are created between the inside or outside of these spacers and the spacers, and a water-stopping agent such as silicon is applied to the joint. In addition, the above-mentioned water-stopping agent flows into these gaps to increase the contact area with the frame material and to increase the holding power of the water-stopping agent by sandwiching the water-stopping agent by the gap, thus preventing the water-stopping agent from peeling off Furthermore, a remarkable effect is exhibited.

Effect of Invention According to Claim 2 When the vertical frame member and the horizontal frame member have a hollow structure, a positioning member is attached to a spacer sandwiched between these joint portions, and the positioning member is engaged with a hollow portion that is formed on the frame member. By doing so, it is possible to easily and reliably manufacture the window frame in which the vertical frame member and the horizontal frame member are joined with the spacer interposed therebetween by positioning the spacer so that a gap having a necessary dimension is generated at a required position. .

Advantageous Effects of Invention According to Claim 3 When the vertical frame material and the horizontal frame material have a foam structure, a positioning member is attached to a spacer sandwiched between these joint portions, and the positioning member is a hole or groove formed in the frame material. If it is engaged, the spacer is positioned so that a gap of the required dimension is formed at the required position, and the window frame in which the vertical frame material and the horizontal frame material are joined with the spacer interposed therebetween is easily and reliably manufactured. be able to.

  Embodiments of a water-stop structure for a window frame according to the present invention will be described below with reference to the drawings.

  In FIG. 1, a symbol A indicates a window frame suitable for a bathroom. The window frame A includes left and right vertical frame members 1 and 2 and upper and lower horizontal frame members 3 and 4 and upper and lower horizontal frames. It is formed by joining with bolt joining members 5 so that the edges of the materials 3 and 4 are in contact with the side edges of the left and right vertical frame materials 1 and 2, A thin plate-like spacer 6 formed narrower than the thickness of the horizontal frame members 3 and 4 is sandwiched between the side edges of the vertical frame members 1 and 2 as shown in FIGS. 8, gaps 7 are formed on the inside and outside of the spacer 6 as shown in FIGS. 8, 9 (a), 9 (b), 10 (c), and FIG. It is characterized by a structure in which a water-stopping agent 8 such as silicon applied to the joint portions 3 and 4 flows in to fill the gap 7.

  The window frame A is formed by joining with the bolt joining member 5 so that the edges of the upper and lower horizontal frame members 3 and 4 are in contact with the side edges of the left and right vertical frame members 1 and 2 as described above. However, the following description will be given with respect to this type, but the joining members are such that the edges of the left and right vertical frame members 1 and 2 are in contact with the side edges of the upper and lower horizontal frame members 3 and 4. The window frame of this type also exhibits the function of preventing the peeling of the water-stopping agent in the same manner. Description is omitted.

  The left and right vertical frame members 1 and 2 and the upper and lower horizontal frame members 3 and 4 are formed by extrusion molding of synthetic resin so as to have a hollow plate shape and have a flange 9 projecting outward at one end in the width direction. The continuous material (not shown) is formed by cutting the length in accordance with the vertical and horizontal dimensions of the window 10 shown in FIG. 1, and as shown in FIG. A plurality of reinforcing ribs 13 for joining the walls 12 and 12 on both sides in the portion 11 and a plurality of screwed portions 14 of the bolt joining member 5 are formed at appropriate intervals, and in accordance with the screwed portions 14. As shown in the lower side in FIG. 2, a plurality of holes 15 through which the bolt joining members 5 are inserted are formed in the upper and lower end portions of the side surface.

  If the outer wall 12 of the vertical frame member 1 having the holes 15 as described above is formed flat, the head of the bolt joining member 5 travels from this surface, and the window frame A is fitted into the window 10. Since it is easy to interfere with the fitting when the window 10 is used, the portion of the outer wall 12 where the hole 15 is opened has a concave portion 16 that is recessed to the extent that the head of the joining member 5 does not travel more than the other portions. Form.

  The spacer 6 is formed by injection molding of synthetic resin so that the length is the same as or slightly shorter than the depth of the horizontal frame members 3 and 4, and the width is narrower than the thickness of the horizontal frame members 3 and 4. When sandwiched between the joints of the vertical frame members 1 and 2 and the horizontal frame members 3 and 4, either the inner side or the outer side as shown in FIG. 8, or the inner side as shown in the circle of FIG. Although not shown, a gap 7 into which the water-stopping agent 8 such as silicon flows is formed only on the opposite outer side, and the water-stopping agent 8 is passed to the hollow portions 11 of the lateral frame members 3 and 4. In order to prevent the inflow, the width of the spacer 6 is set so that the hollow portion 11 is closed.

  The spacer 6 engages with the hollow portion 11 formed in the lateral frame members 3 and 4 on the back side as shown in FIGS. 3, 4, and 5, and the reinforcing rib 13 and the screwing portion 14 of the joining member 5. In this structure, a positioning member 17 is formed to regulate the position in the front-rear direction. A plurality of through holes 18 of the joining member 5 aligned with the screwing portion 14 are formed on the surface of the spacer 6. Yes.

Next, the formation of the window frame A and the action of preventing peeling will be described with reference to FIGS.
As shown in FIG. 6, the spacer 6 is attached to the hollow portion 11 by engaging the positioning member 17 with the left end edge of the lower horizontal frame member 4, and then, as shown in FIG. A jig 20 having a guide hole 19 formed at the same position and interval is applied to the screwing portion 14 formed in the horizontal frame member 4 on the lower outer side, and the vertical frame is aligned with the guide hole 19 of the jig 20. A plurality of holes 15 are drilled with cones 21 at the lower end of the material 1. Then, the lower end of the vertical frame member 1 is applied to the spacer 6 so that the hole 15 matches the through hole 18 formed in the spacer 6 as shown in FIG. The lower left corner of the vertical frame member 1 and the horizontal frame member 4 are joined with the spacer 6 interposed therebetween so that the upper left corner, the lower right corner and the upper right corner of the window frame A are joined. If a similar joining operation is performed in each place, the window frame A as shown in FIG. 1 can be easily formed.

  In the window frame A formed as described above, the spacer 6 is sandwiched between the joint portions of the vertical frame members 1 and 2 and the horizontal frame members 3 and 4, respectively, both inside and outside, or the circle in FIG. As shown in the figure, the gap 7 sandwiched between the vertical frame member 1 and the horizontal frame member 4 is formed only on the inner side or not on the drawing, but only on the opposite outer side. As shown in FIG. 10, if a water-stopping agent 8 such as silicon is applied to the part, the water-stopping agent 8 flows into the gaps 7 and 7 and is filled in the gaps 7. In addition, the water stop agent 8 is sandwiched by the gap 7 and the holding power of the water stop agent 8 is increased. Therefore, the water stop agent 8 that is easily generated in the window frame that does not form the gap 7 in the joint portion is formed. Peeling hardly occurs.

  The gap 7 formed by the spacer 6 at the joint between the vertical frame members 1 and 2 and the horizontal frame members 3 and 4 has a width of 300 mm, a height of 300 mm, and a depth of 200 mm. It is appropriate to set the width to 0.5 mm to 5.0 mm, preferably 1.0 mm to 2.5 mm, and the depth to 0.2 mm to 1.8 mm, preferably 0.6 mm to 1.5 mm. Then, the width of the gap 7 is set to 1.5 mm and the depth is set to 0.7 mm, and a silicone water-stopping agent 8 is applied to the joint between the vertical frame member 1 and the horizontal frame member 4 corresponding to the gap 7. Then, the water-stopping agent 8 flows into the gap 7 and fills the gap, increasing the contact area between the water-stopping agent 8 and the vertical frame member 1 and the horizontal frame member 4 and sandwiching the water-stopping agent 8 by the gap 7. In order to increase the holding power of the water-stopping agent 8, even if the water-stopping agent 8 peels off in the contrast test window frame without a gap, Had never produce adopted in the window frame A peeling bright.

  In addition, the spacer 6 in FIG. 3 is formed as the short length divided into a plurality of the same length as the width of the horizontal frame member 4 as shown in FIG. When the vertical frame material 1 and the horizontal frame material 4 are joined by the joining member 5 by being sandwiched between the joint portions of the vertical frame material 1 and the horizontal frame material 4 so as to be separated from each other, the inside or the outside of each spacer 6 A gap 7 whose width and depth are regulated by the spacer 6 is formed between the spacers 6 and 6, and a communication gap 7 ′ is formed between the spacers 6 and 6. When applying the water-stopping agent 8 to the joint, since the inflow of the water-stopping agent 8 is not restricted, more water-stopping agent flows than the gap 7 portion, and more water-stopping agent than the gap 7 portion. 8 is filled, and the contact area between the vertical frame members 1 and 2 and the horizontal frame members 3 and 4 is increased, and a water-stopper is sandwiched therebetween. Since the action of strengthening the force is promoted, the effect of preventing the water-stopping agent 8 from peeling can be further enhanced.

  Further, the spacer 6 is formed into a short frame shape as shown in FIG. 5, and some of the spacers 6 are arranged at equal intervals as shown in FIG. 9 (c). If the joining vertical frame members 1 and 2 and the lateral frame members 3 and 4 are joined together, a short gap 7 whose width and depth are regulated is generated inside or outside each spacer 6. Between the spacers 6 and 6, there are a plurality of communication gaps 7 ′ extending from the inside to the outside. The communication gaps 7 ′ flow into the water stop agent 8 when the water stop agent 8 is applied to the joint. Therefore, more water-stopping agent 8 flows in and is filled than the gap 7, so that the contact area between the water-stopping agent 8, the vertical frame member 1 and the horizontal frame member 4 is increased, and a plurality of communication is provided. Since the force to sandwich the water-stopping agent 8 in the gap 7 ′ is strengthened and the holding power of the water-stopping agent 8 is further increased, the effect of preventing the water-stopping agent 8 from peeling off is It is improved with the stage.

  In this embodiment, the vertical frame members 1 and 2 and the horizontal frame members 3 and 4 are not joined by the bolt joining member 5, but as described in Japanese Patent Application Laid-Open No. 2009-161992. Can be joined by forming insertion parts on the outer surfaces of the lateral frame members 3 and 4 and inserting L-shaped joining members into these insertion parts. Since this process is performed in the same manner as that described in Japanese Unexamined Patent Publication No. 2009-161992, drawings and explanations relating to the joining structure are omitted with the aid of this publication.
