Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gap portion between the side wall of the joinery frame and building a window frame or the like of buildings waterproof waterproofing.
[0002]
[Prior art]
Conventionally, as a structure of a boundary portion between a joiner frame such as a window frame or a door frame of a building and a side wall of the building, for example, one as in Patent Document 1 can be cited.
[0003]
In the waterproof structure of the present invention, as shown in FIG. 9, it is a lower corner portion of the boundary portion between the aluminum sash 114 serving as a joinery frame and the side wall frame 108 of the building, and the aluminum sash 114 and the side wall frame 108. A waterproof body 116 is interposed so as to fill the gap between the two. The waterproof body 116 includes an intrusion prevention portion 118 disposed so as to be in contact with the inner surface of the aluminum sash 114, a lead-out portion 120 disposed between the lower surface of the aluminum sash 114 and the side wall frame 108, and an outer surface of the side wall frame 108. The guide part 122 arrange | positioned so that it may contact. And, in the case of strong wind and rain such as typhoon, the rainwater enters mainly from the lower corner of the aluminum sash 114 into the building. Is prevented, and further, led to the lead-out part 120 and the guide part 122 to be discharged outside the building.
[0004]
However, since the waterproof structure is based on the premise that both the front and back surfaces of the waterproof body 116 are in close contact with the aluminum sash 114 and the side wall frame 108, the gap between the aluminum sash 114 and the side wall frame 108 is equal to the thickness of the waterproof body 116. For example, it is not applicable to a structure that absorbs a dimensional error with a large space between the joinery frame and the side wall.
[0005]
Thus, for example, the following structure exists as a structure that more flexibly corresponds to the size of the gap. As shown in FIG. 1, this waterproof structure includes a window 100 and a side wall 130. As shown in FIG. 10 (AA sectional view in FIG. 1), the window 100 includes three window glasses 101, a window inner frame 103, and a window outer frame 105. The side wall 130 has an inner wall material 132 disposed on the inner side (upper side in FIG. 10) of the pillar 131, a plywood 133 disposed on the outer side (lower side in FIG. 10), and a fixed distance from the plywood 133. The outer wall member 135 is disposed outside, the air passage edge 137 disposed at a predetermined interval in the gap between the plywood 133 and the outer wall member 135, and the window outer frame 105. And an outer frame 138 for supporting the outer wall material 135. In addition, an air passage layer 139 is formed between adjacent air cylinder edges 137.
[0006]
Both side surfaces of the window inner frame 103 and the window outer frame 105 are connected by arm members 107. The arm member 107 includes two arms 107a and 107b and three pins 107c, 107d, and 107e. The window outer frame 105 and the arm 107a, the arms 107a and 107b, and the arm 107b and the window inner frame are provided. 103 are respectively connected by pins 107c, 107d, and 107e so as to be rotatable around the pin axis. That is, as shown in FIG. 3, the window inner frame 103 is rotatable in the vertical direction via the arm member 107.
[0007]
Returning to FIG. 10, the description will be continued. In the gap between the window outer frame 105 and the column 131, the packing material 111 is installed, and the caulking portions 113 are arranged at both ends of the packing material 111. The caulking portion 113 is formed by injecting and solidifying silicon resin, epoxy resin, or the like between the window inner frame 103 and the pillar 131, and is bonded to the window inner frame 103 and the pillar 131. Thus, the gap between the window inner frame 103 and the pillar 131 is sealed.
[0008]
[Patent Document 1]
Japanese Utility Model Publication No. 61-87877 [0009]
[Problems to be solved by the invention]
However, since the caulking material 113 can hardly be deformed when it is solidified, the caulking material 113 is merely displaced by the relative position between the window outer frame and the joinery frame due to vibrations such as earthquakes or changes with time. There is a possibility that a large stress will be generated on the surface and a crack will occur, resulting in a deterioration of the waterproof function.
[0010]
Accordingly, the present invention, the fittings frame such window frames, reliably ensure the sealing of the gap portion between the side wall, the waterproof structure of the joinery frame capable of preventing the rainwater from entering the building the to provide.
[0011]
[Means for Solving the Problems]
The present invention is based on the idea that the gap formed at the boundary between the joinery frame of the building and the side wall of the building is covered with a resin plate instead of being filled with the caulking material. However, such a resin plate is easy to bend and deform in the thickness direction, but the expansion and contraction deformation in the direction perpendicular to the thickness direction is limited to a very small range compared to the bending deformation. Even if a resin plate is interposed between the joinery frame and the side wall portion, the relative displacement of both members cannot be absorbed.
[0012]
Therefore, the waterproof structure of the building according to the present invention, there is provided a waterproof structure for by that building to cover the gap formed in the boundary portion between the side wall portions of the joinery frame and building of buildings, the and building resin waterproof plate for covering the gap, an outer wall material for covering the side wall portion from the outside, is arranged on the outside of the fitting frame, and an outer frame for supporting the outer walls, for the building The resin waterproof board has a shape that can be in close contact with the outer surface of the joinery frame of the building, and is substantially the same as the first fixing portion that is fixed to the outer surface of the joinery frame in the contact state, and the first fixing portion. A second fixing portion that is parallel and has a shape that can be in close contact with the outer surface of the side wall portion of the building , and is fixed to the outer surface of the side wall portion in the close contact state, and the first fixing portion and the second fixing portion. and a bending deformation portion is formed between the parts, the bending deformation portion, the first fixing part and Serial with bulging in a direction substantially perpendicular to these a second fixing portion has a shape that can fits into the gap, by the bending deformation portion is bending deformation to the entire said resin waterproof plate is retractable, the The outer frame is arranged so as to cover the first fixing part fixed to the outer side surface of the joinery frame from the outside, and the outer wall material is arranged outside the second fixing part fixed to the outer side surface of the side wall part. It is arrange | positioned so that it may cover .
[0013]
In this structure, since the resin waterproof board for buildings can be expanded and contracted by bending and deforming the bending deformation portion, the relative position between the joinery frame and the side wall is shifted. Even in the case, the bending deformation part causes bending deformation to absorb the deformation related to the shift, and a large stress does not act on the resin waterproof board, so that the crack is hardly generated.
[0014]
Further, the resin waterproof board is fixed so that the first fixing portion is in close contact with the outer surface of the joinery frame, and the second fixing portion is fixed so as to be in close contact with the outer surface of the side wall. And rainwater and the like are reliably prevented from entering through the gap between the outer surface of the joinery frame and the gap between the second fixing portion and the outer surface of the side wall. Therefore, the waterproof effect can be improved reliably.
[0015]
Further, a waterproof structure of the joinery frame, fixed so bent bulge of the deformed portion of the resin waterproof plate the first fixing part in a state where Hamarikomu in the gap portion is in close contact with the outer surface of the joinery frame In addition, by fixing the second fixing portion so as to be in close contact with the outer side surface of the side wall, at least a portion of the bulging portion of the bending deformation portion that fits into the gap portion. Further, it is possible to avoid projecting from the joinery frame and the side wall or to reduce the projecting amount, thereby ensuring a good aesthetic appearance.
[0016]
As described in claim 2, in the configuration in which the bending deformation portion has a substantially constant cross-sectional shape in the arrangement direction of the first fixing portion and the second fixing portion, the plate can be cut anywhere. Since the same function can be secured, high versatility can be obtained by cutting the resin waterproof board into a desired length according to the location where the resin waterproof board is installed.
[0017]
Further, as described in claim 3, the bulge of the bending deformation portion is provided with an acute angle portion when the section in the arrangement direction of the first fixing portion and the second fixing portion is curved. Stress concentration is less likely to occur than in the case, and cracking is less likely when the bending deformation occurs. In addition, since the bending deformation portion can be smoothly fitted in the gap portion, the burden of installing the resin waterproof board can be reduced.
[0018]
In addition, as described in claim 4, the first fixing portion is formed in a shape along the corner portion of the joinery frame, and the second fixing portion is formed in a shape along the corner portion of the side wall portion. By covering the gap formed at the boundary portion between the corner portion of the joinery frame and the corner portion of the side wall portion and enabling waterproofing of the building, the corner portion of the joinery frame and the side wall It is possible to ensure waterproofing even in the gap at the boundary between the corner and the part.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. However, the present invention is not limited to the following embodiments.
[0020]
1st Embodiment (refer FIGS. 1-5)
The waterproof structure of this embodiment is mainly applied between the window outer frame 105 and the side wall 130 as shown in FIG. Hereinafter, this waterproof structure will be described with reference to FIG. 2, which is a cross-sectional view taken along the line AA of FIG. As described above, the window 100 includes the three window glasses 101, the window inner frame 103, and the window outer frame 105. As in the prior art, the side wall 130 includes an inner wall member 132 disposed on the inside (upper side in FIG. 2) of the pillar 131, a plywood 133 disposed on the outer side (lower side in FIG. 2), and a plywood. 133, an outer wall member 135 installed on the outer side with a certain distance from 133, an air passage edge 137 disposed with a predetermined interval with respect to a gap portion between the plywood 133 and the outer wall member 135, and the window outer frame 105 The outer frame 138 is provided on the outer side and supports the outer wall member 135. In addition, an air passage layer 139 is formed between adjacent air cylinder edges 137. A packing material 111 is installed in the gap between the window outer frame 105 and the column 131. The window outer frame 105 and the window inner frame 103 are connected by the above-described arm member 107 (see “Prior Art”), so that the window inner frame 103 is vertically moved as shown in FIG. It can be rotated. In addition, the resin waterproof board 140 is arrange | positioned so that the outer surface of the window outer frame 105 and the outer surface of the plywood 133 may be contacted, and the said gap | interval may be covered. Further, one end of the resin waterproof board 140 is in a state of being connected to an outer wall waterproof sheet 151 that covers the outer surface of the plywood 133.
[0021]
The said resin waterproof board 140 is demonstrated below using FIG.4 and FIG.5.
[0022]
The resin waterproof board 140 includes a first fixing part 141, a second fixing part 143, and a bending deformation part 145. The first fixing part 141 and the second fixing part 143 are formed in a substantially flat plate shape, and both parts are arranged substantially in parallel. A bending deformation portion 145 is provided between the first fixing portion 141 and the second fixing portion 143, and these members are molded so as to be integrated.
[0023]
FIG. 5 is a plan view of the resin waterproof board 140. Referring to this figure, the bending deformation portion 145 is a line connecting the end portion of the first fixing portion 141 and the end portion of the second fixing portion 143. That is, it is formed so as to swell from the line segment B. Specifically, the cross-section when cut in the plate thickness direction has a shape protruding in a substantially U shape with respect to the plate thickness direction, and this shape is a substantially constant shape in any cross-section. ing. And the single side | surface of the double-sided tape 147 is stuck on the single side | surface of the 1st fixing | fixed part 141 and the 2nd fixing | fixed part 143.
[0024]
In addition, as a raw material used for this resin waterproof board 140, synthetic resins, such as polyethylene and vinyl chloride, etc. are mainly used. The characteristics of these materials are that they have shape retention and are easy to bend and deform in the thickness direction, but the expansion and contraction deformation in the direction perpendicular to the thickness direction is extremely small compared to the bending deformation. It is limited to such a range. That is, when tensile or compressive stress is applied mainly in the direction in which the first fixing portion 141 and the second fixing portion 143 are arranged (C direction in FIG. 5) or in the plate thickness direction (D direction in FIG. 5), When the bending deformation portion 145 is bent and deformed, the entire resin waterproof board 140 is expanded and contracted.
[0025]
Returning to FIG. 2, the continuation of the installation state of the resin waterproof board 140 will be described. The waterproof resin plate 140 is fixed by a double-sided tape 147 so that the first fixing portion 141 is in close contact with the window outer frame 105 and the second fixing portion 143 is in close contact with the plywood 133. Further, the bending deformation portion 145 is disposed so as to fit in the gap between the window outer frame 105 and the pillar 131 and the plywood 133. And the bending deformation part 145 deform | transforms according to the relative movement of the position of the window outer frame 105 and the side wall 130 in the direction which contacts / separates mutually.
[0026]
In this case, the resin waterproof board 140 expands and contracts in the arrangement direction (C direction in FIG. 5) and the plate thickness direction (D direction in FIG. 5) when the bending deformation portion 145 is bent and deformed. Since it is possible, it is a relative position between the window outer frame 105 and the side wall 130, and the arrangement direction of the window outer frame 105 and the side wall 130 (direction F in FIG. 2), and the window outer frame 105 and the side wall 130. When the displacement occurs in the thickness direction (E direction in FIG. 2), the bending deformation portion 145 causes bending deformation, so that the deformation related to the displacement is absorbed, and the resin waterproof board 140 is not subjected to a large stress and cracks. Is less likely to occur. Therefore, even when the relative position is shifted and the packing material 111 is not in close contact with the pillar 131 and the outdoor frame 105, rainwater and the like are prevented from entering the gap between the window outer frame 105 and the side wall 130. It becomes possible to do.
[0027]
In addition, when a deviation occurs in the thickness direction (the E direction in FIG. 2) between the window outer frame 105 and the side wall 130, the bending deformation portion 145 causes bending deformation, so that deformation related to the deviation is absorbed. Even if a shift occurs, the first fixed portion 141 and the second fixed portion 143 are hardly deformed. Therefore, even when a shift occurs in the thickness direction (E direction in FIG. 2) between the window outer frame 105 and the side wall 130 among the relative positions, the first fixing portion 141 and the second fixing portion 143 It does not float from the outer surface of the outer frame 105 and the outer surface of the side wall 130, and the beauty is maintained.
[0028]
Further, the resin waterproof board 140 is fixed so that the first fixing portion 141 is in close contact with the outer surface of the window outer frame 105, and the second fixing portion 143 is fixed so as to be in close contact with the outer surface of the side wall 130. Rainwater or the like can be reliably prevented from entering from the gap between the first fixing portion 141 and the window outer frame 105 and the gap between the second fixing portion 143 and the outer surface of the side wall 130. Therefore, the waterproof effect can be improved reliably.
[0029]
In addition, since this resin waterproof board 140 has shape retention property, the installation work of the resin waterproof board 140 should be performed only by fitting the bending deformation part 145 into the gap between the window outer frame 105, the pillar 131, and the plywood 133. The burden of installation work is reduced compared to the case without shape retention.
[0030]
Further, since the bulging portion of the bending deformation portion 145 is disposed in the gap portion, it is avoided that the bending deformation portion 145 protrudes from the window outer frame 105 and the side wall 130. Therefore, a good aesthetic appearance can be ensured.
[0031]
Furthermore, since the shape of the bending deformation portion 145 is substantially constant in the cross-sectional shape in the arrangement direction of the first fixing portion 141 and the second fixing portion 143, the same function can be ensured regardless of where the plate is cut. The resin waterproof board 140 can be cut to a desired length depending on the location where the resin waterproof board 140 is installed. Therefore, higher versatility can be obtained.
[0032]
Further, since the shape of the bulging portion of the bending deformation portion 145 is U-shaped, that is, a curved surface shape in the cross-sectional shape in the arrangement direction, stress concentration is less likely to occur compared to the shape provided with an acute angle portion, and It becomes more difficult to crack when bending deformation occurs. Furthermore, since the bending deformation part 145 can be smoothly fitted into the gap between the window outer frame 105, the pillar 131, and the plywood 133, the burden of the installation work of the resin waterproof board 140 is reduced.
[0033]
Second embodiment (see FIG. 6)
In the following embodiments, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.
[0034]
6A and 6B, at least the first fixing portion 141 is formed in a shape along the corner portion of the window outer frame 105, and the second fixing portion 143 is in a shape along the corner portion of the side wall 130 portion. The specific shape is shown below.
[0035]
6A, the first fixing portion 141 and the second fixing portion 143 are formed in a substantially L-shaped plate shape so as to follow the corner portions of the window outer frame 105 and the side wall 133, respectively. And the bending deformation part 145 is shape | molded by the substantially L shape seeing from the plate | board thickness direction so that this 1st fixing | fixed part 141 and the 2nd fixing | fixed part 143 may be connected in the state arranged in parallel substantially.
When this resin waterproof board 140 is used, the gap formed at the boundary between the corner portion of the window outer frame 105 and the corner portion of the side wall 130 can be covered with one resin waterproof board 140. Therefore, the number of joints can be reduced as compared with the case where a plurality of resin waterproof boards are joined and covered, and the corner portion of the gap can be waterproofed more reliably. Furthermore, since the number of processes for constructing the waterproof resin plate at the corner portion can be reduced, the labor of construction can be reduced.
[0036]
Moreover, like the resin waterproof board 140 of FIG.6 (b), the 1st fixing | fixed part 141 and the 2nd fixing | fixed part 143 are formed in substantially U-shaped plate shape, and the bending deformation part 145 is plate | board thickness. Two corner portions adjacent to each other among the gap portions formed at the boundary portion between the window outer frame 105 and the side wall 130 by being formed into a substantially U-shape when viewed in the direction, and such corners Since the portion sandwiched between the portions can be covered with one resin waterproof board 140, the labor of construction can be further reduced.
[0037]
3rd Embodiment (refer FIG. 7, FIG. 8)
The resin waterproof board 140 of the present invention is such that the bending deformation portion 145 swells from a line connecting the end portion of the first fixing portion 141 and the end portion of the second fixing portion 143 (line B ′ in FIG. 7). There is no particular limitation as long as it is formed. For example, as in the present embodiment, the bending deformation portion 145 may include a portion that swells in the plate thickness direction and a portion that swells in the direction in which the first fixing portion 141 and the second fixing portion 143 are arranged .
[0038]
Also in this case, the resin waterproof board 140 has the entire resin waterproof board 140 aligned with the first fixed part 141 and the second fixed part 143 (the C direction in FIG. 7) due to the bending deformation part 145 bending. Since it can be expanded and contracted in the plate thickness direction (D direction in FIG. 7), it is the relative position between the window outer frame 105 and the side wall 130, and the alignment direction of the window outer frame 105 and the side wall 130 (in FIG. 8). F direction) and the thickness direction between the window outer frame 105 and the side wall 130 (the E direction in FIG. 8), the bending deformation portion 145 causes bending deformation to absorb the deformation related to the above displacement. The
[0039]
Other Embodiments (1) The entire bulging portion of the bending deformation portion 145 does not necessarily need to fit into the gap portion between the window outer frame 105 and the side wall 130, and only a part of the bulging portion may be fitted. For example, it is conceivable that the bending deformation portion 145 has a plurality of bulging portions, and only a part of the bulging portions fits into the gap portion. Even in this case, the bending deformation portion 145 can reduce the portion protruding from the window outer frame 105 and the side wall 130, and is effective in securing a good aesthetic appearance.
[0040]
(2) The window 100 is not limited to the form in which the indoor frame 103 and the window glass 101 rotate in the vertical direction. A type in which the indoor frame 103 itself is fixed or a plurality of indoor frames are provided. Arbitrary forms such as a type in which the window 100 opens and closes by sliding the indoor frame can be taken.
[0041]
(3) The shape of the bending deformation part 145 does not necessarily have a U-shaped cross-sectional shape. For example, an arbitrary cross-sectional shape such as a U-shape, a triangle shape, and a wave shape can be adopted.
[0042]
(4) The joinery frame as a target adopting the waterproof structure of the present invention is not limited to the window outer frame 105, that is, the window frame. For example, you may make it install the resin waterproof board concerning the boundary part of a door frame and a side wall.
[0043]
(5) In 2nd embodiment, the 1st fixing | fixed part 141 and the 2nd fixing | fixed part 143 are not necessarily limited to L shape and a U-shape, The corner part of the window outer frame 105 and the side wall 130 is not necessarily limited. The shape is not particularly limited as long as the shape is in line with the shape.
[0044]
【The invention's effect】
As described above, the waterproof structure of a building according to the present invention includes a resin waterproof board , and at least a part thereof is orthogonal to the direction in which the first fixing portion and the second fixing portion are arranged. It is formed in a shape that swells in the direction, and when the portion is bent and deformed, the entire resin waterproof board can be expanded and contracted in the arrangement direction. In this case, even when a shift occurs in the relative position between the joinery frame and the side wall, the bending deformation portion absorbs a deformation related to the shift by causing a bending deformation, and a large stress does not work on the resin waterproof board, Cracks are less likely to occur. Therefore, the waterproof effect can be improved more reliably.
