BACKGROUND OF THE INVENTION
The present invention relates to an installation structure of a joinery frame that is a frame body such as a window or a door installed in an opening of a building, and a joinery frame.
[0002]
[Prior art]
5 and 6 show the installation structure of a window frame (joint frame) in a conventional sliding window. In this window frame 51, an upper frame 52, a lower frame, and both vertical frames 53 are framed by a so-called vertical frame, and a flange portion 54 formed on the outer periphery of each component frame is provided at an opening of the building. A window frame is obtained by attaching a seal tape 55 so as to straddle the flange portion 54 and the joinery support material over the four circumferences of the window frame 51 after nailing to a joinery support material (window lintel, window stand, etc.). 51 is watertightly fixed to the joinery support material. Further, a gap between the outer peripheral surface of the window frame 51 and the outer wall material 56 facing the opening is filled with a sealing material 57 such as a caulking material facing the outdoors. Thus, the window frame 51 is sealed with the outer wall material 56 by the sealing material 57 in the prospective direction, and is sealed with the joinery support material by the sealing tape 55.
In addition, both figures represent the state in which the sealing material 57 deteriorates and the seal is broken on the upper surface of the upper frame 52. Since the seal material 57 on the upper surface of the upper frame 52 is easily deteriorated by being exposed to direct sunlight, a gap may be generated between the seal material 57 and the outer wall material 56 due to aging, and the seal may be cut. Assuming the worst state due to such a seal breakage, the rainwater blown from this portion flows down from the both ends of the upper frame 52 to the vertical frame 53, but the upper side of the upper frame 52 using the sealing material 57 as a weir. It is conceivable to store in
[0003]
[Problems to be solved by the invention]
By the way, when the window frame 51 is framed through the vertical frame, a sealer 58 is interposed between the inner surface of the upper end of the vertical member 53 and the small edge of the upper frame 52 (the same applies to the lower frame). ing. In this case, the sealer 58 is formed to be slightly larger than the small edge of the upper frame 52 so that the sealer 58 is securely sandwiched. As described above, the window frame 51 that is framed with the sealer 58 interposed therebetween is sandwiched even if, for example, the joint portion between the vertical frame 53 and the upper frame 52 in the flange portion 54 is flush. The edge of the sealer 58 protrudes slightly. For this reason, the seal tape 55 is stuck in a state where the sealer 58 is raised. That is, the slightly projecting sealer 58 creates two gaps 59 having a triangular cross section extending in the vertical direction inside the seal tape 55.
On the other hand, as shown in the drawing, the seal tape 55 is attached using the notch at the end of the vertical frame 53 and the base of the flange portion 54 as a guideline. Therefore, when rainwater accumulates on the upper surface of the upper frame 52 as described above, The lower end portion of the seal tape 55 is immersed in rain water (see FIG. 6). When the lower end portion of the seal tape 55 is immersed in rainwater, rainwater may invade and rise from the triangular gap 59 due to wind pressure or capillary action, and may leak over the flange portion 54 to the indoor side. was there. In other words, the seal tape 55 may cause water leakage depending on the sticking form.
[0004]
An object of the present invention is to provide a joinery frame installation structure and a joinery frame capable of effectively preventing water leakage to the indoor side from a gap formed inside the seal tape.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, with reference to the attached drawings, a case where a fitting frame installation structure and a fitting frame according to an embodiment of the present invention are applied to a sliding window will be described. As shown in the longitudinal sectional view of FIG. 1, this sliding window 1 includes a window frame 2 attached to the opening A of the building, and a shoji made up of an outer obstacle 3a and an inner obstacle 3b attached to the window frame 2 so as to be opened and closed. 3 and a screen door 4 attached to the window frame 2 on the outdoor side of the shoji 3 so as to be freely opened and closed. In the opening A of the building, a window lintel Ba and a window sill Bb are spanned between left and right columns (not shown), and a window frame support material (joint support material) B that is open in a square shape is configured. In this case, a flange portion 6 is formed on the outer peripheral portion of the window frame 2, and the sliding window 1 is installed in the opening portion A by pressing the flange portion 6 against the window frame support B from the outdoor side. It has come to be.
[0022]
And the sealing tape 7 is stuck over said flange part 6 and the window frame support material B, and the seal | sticker between the window frame 2 and the window frame support material B is made | formed. In addition, an outer wall material C is disposed on the outdoor side of the window frame support member B in the prospective direction, with a gap, and the gap between the outer wall material C facing the opening B and the window frame 2 has four rounds. A sealing material 8 made of a caulking material (more precisely, a caulking material and a backup material) is filled (intervened). Thus, the window frame 2 is double-sealed with respect to the opening A of the building by the sealing material 8 and the sealing tape 7.
[0023]
The window frame 2 is constituted by an upper frame 11, a lower frame 12, and left and right vertical frames 13, which are each formed of an aluminum shape, and are framed around four sides. In this case, only the periphery of the upper frame 11 is shown in FIG. 2, but the left and right vertical frames 13 with respect to the upper frame 11 and the lower frame 12 are framed in a so-called vertical passage (vertical frame passage). More specifically, for example, in the portion of the upper frame 11, a sealer (rubber sealer) 15 formed slightly larger (wider) than the cross-sectional shape of the small frame end of the upper frame 11 is connected to the small frame end of the upper frame 11. The upper frame 11 and the vertical frame 13 are joined to each other by screws. Although not shown, the lower frame 12 is also framed in the same manner as the vertical frame 13.
[0024]
On the other hand, the upper frame 11, the lower frame 12, and the vertical frames 13 are respectively formed with flange pieces 11b, 12b, 13b on the outer peripheral portions of the frame bodies 11a, 12a, 13a. In a state where the frame 13 is framed, the flange pieces 11b, 12b, and 13b continuously constitute the flange portion 6 described above. Then, each of the flange pieces (flange portion 6) 11b, 12b, 13b is appropriately nailed or screwed to the window frame support material B, so that the window frame (the sliding window 1) 2 becomes the window frame support material (opening). Part A) is fixed to B. Furthermore, after fixing the window frame 2 to the window frame support member B, the upper tape piece 17, the lower tape piece 18, and so on over the flange portion 6 and the window frame support material B over the four circumferences of the window frame 2. A seal tape 7 composed of both vertical tape pieces (not shown) is attached.
[0025]
By the way, as described above, the sealer 15 formed to be slightly larger than the cross-sectional shape of the edge of the upper frame 11 has its end slightly slightly from the joint portion (butting portion) between the upper frame 11 and the vertical frame 13. It will protrude (see FIG. 2 and FIG. 3). In addition, the upper end of each vertical frame 13 is cut out in accordance with the cross-sectional shape of the upper frame 11 in order to form a four-round continuous flange portion 6, but this notch portion 14 is not shown, but on the flange piece 13 b side. There may be a slight leaving of the convex portion. In such a case, as shown in FIG. 4, the upper tape piece 17 of the seal tape 7 adhered horizontally to the upper frame 11 part is raised (floated) by the sealer 15 or the convex portion. It is stuck in the state.
[0026]
Then, a pair of gaps 19, 19 having a triangular cross section are formed inside the portion of the upper tape piece 17 that is lifted by the sealer 15 or the convex portion. That is, a gap 19 extending in the vertical direction is generated between the joint portion of the vertical frame 13 and the upper frame 11 and the upper tape piece 17 by the sealer 15 or the like. Although this gap 19 will be described later, it causes water leakage based on the capillary phenomenon. Therefore, in this embodiment, the sticking form of the seal tape 7 is devised in order to prevent this.
[0027]
Here, with reference to FIG. 2 and FIG. 3, the sticking form of the seal tape (upper tape piece 17) 7 around the upper frame 11 will be described in detail. Both figures show a state where the seal material (caulking material) 8 is deteriorated and a gap S is generated between the seal material 8 and the outer wall material C (seal breakage). When a gap S is generated between the sealing material 8 and the outer wall material C, rainwater is blown from the gap S. Of course, the rainwater blown in flows from the left and right ends of the upper frame 11 to the vertical frame 13 side. However, in the worst state, the sealing material 8 serves as a weir and the rainwater is stored on the upper surface of the upper frame 11. If the lower end portion of the seal tape (upper tape piece 17) 7 is immersed in the stored rainwater, the rainwater is sucked up from the gap 19 by capillary action, and when wind pressure or the like acts on the rainwater, It will leak.
[0028]
Therefore, in anticipation of an assumed maximum water level L of rainwater stored instantaneously, in the embodiment, the seal tape 7 is attached so that the lower end is on the upper side from the maximum water level L. In this case, the assumed maximum water level L is assumed to be lower than the upper end of the sealing material 8 in FIG. 3 in the window frame 2 where rainwater easily flows from the left and right ends of the upper frame 11. Therefore, in consideration of safety, the seal tape 7 is affixed so that the lower end of the seal tape (upper tape piece 17) 7 is positioned above the upper end of the seal material, preferably sufficiently above. You may make it wear.
[0029]
Since the attachment of the seal tape 7 is left to the workers at the site, the upper tape piece 17 is attached to the flange piece 11b of the upper frame 11 so that the upper tape piece 17 is correctly attached. A mark 21 indicating the lower end position is provided. In addition, a caution sticker 22 on which a description that the mark 21 indicates a sticking lower end position of the seal tape 7 is attached to both left and right end portions (or an end portion on one side) of the upper frame 11. Yes. More specifically, it is preferable that the mark 21 is a concave portion or a convex portion formed in the upper frame 11 which is an extruded shape member. Of course, the mark 21 may be attached in a straight line or a marking line on the flange piece 11b or in a seal form. Further, the mark 21 is not necessarily represented by a continuous line. For example, the indication line 22a described in the above caution sticker 22 can also serve as the mark 21.
On the other hand, it is preferable that the caution note seal 22 is peeled off from a tape with release paper or the like and stuck. Of course, the caution sticker 22 may be attached to the upper end of the vertical frame 13.
[0030]
In any case, the sticking lower end position of the sealing tape (upper tape piece 17) 7 is expected to be slightly different depending on the height dimension of the sealing material (caulking material) 8, the degree of inclination of the upper frame 11, and the like. The Therefore, the height position (the height position from the base end of the flange piece 11b) is obtained and set for each product by experiments or the like. Generally, since the assumed maximum water level L of the stored rainwater is expected to be about 10 mm to 13 mm, the sticking lower end position of the seal tape 7 has a dimension exceeding this.
[0031]
As described above, according to the present embodiment, even if rainwater is stored on the upper surface of the upper frame 11 due to the seal being cut, the lower end portion of the seal tape 7 is not immersed in the stored rainwater. Even if the seal tape 7 is stuck so that a gap 19 is formed inside thereof, it is possible to structurally prevent the rainwater from being sucked up by the capillary phenomenon. Therefore, water leakage to the indoor side based on the stuck seal tape 7 can be prevented with a simple configuration.
[0032]
The mark 21 may be written on the window frame support material B as a marking line indicating the sticking lower end position or the sticking upper end position of the seal tape 7. Moreover, it cannot be overemphasized that this invention is applicable not only to a sliding window but to frame bodies, such as various windows and a door installed in the opening part of the building which faces the outdoors.
[0033]
【The invention's effect】
As described above, according to the installation structure of the joinery frame of the present invention, the lower end of the upper tape piece is stuck so as to be positioned above the assumed maximum water level of the rainwater or the upper end of the sealing material, and rainwater due to capillary action is attached. Since sucking can be prevented, leakage to the indoor side based on the sticking form of the seal tape can be effectively prevented.
[0034]
In addition, according to the joinery frame of the present invention, the mark provided on the upper frame can instruct the worker at the site of the sticking lower end position of the seal tape. Can be attached so that the lower end position is located above the assumed maximum water level of rainwater or the upper end of the sealing material. Thereby, the water leakage to the indoor side based on the sticking form of a seal tape can be prevented effectively.
