Description

The present invention relates to building materials for openings.

Conventionally, building materials for openings have been known that are constructed by fitting a sash frame into an opening in a building frame from the outside. There has been a demand for improving the ease of construction of such building materials for openings.

In view of the above-mentioned circumstances, the present invention aims to improve the workability of building materials for openings.

In order to achieve the above object, the opening construction material according to the invention described in claim 1 comprises a sash frame and a position adjustment part, the position adjustment part is attached to the outer peripheral side of the vertical frame, and a plurality of elastic pieces protruding toward the outer peripheral side are provided at intervals in the indoor and outdoor directions, and the elastic pieces on the outdoor side protrude farther toward the outer peripheral side than the elastic pieces on the indoor side.

The opening construction material according to the invention described in claim 1 comprises a sash frame and a position adjustment part. The position adjustment part is attached to the outer peripheral side of the vertical frame, and multiple elastic pieces protruding toward the outer peripheral side are provided at intervals in the indoor and outdoor directions. When the sash frame is placed in the opening of the structural body from the outside, the elastic pieces of the position adjustment part elastically deform and press the side edges of the opening of the structural body, positioning the sash frame in the center position in the left-right direction of the opening of the structural body. Moreover, because the elastic pieces on the outside of the room protrude farther toward the outer peripheral side than the elastic pieces on the inside of the room, it is easy to place the sash frame in the opening of the structural body from the outside, improving workability.

This is an oblique view of the corner portion between the vertical frame and the lower frame, viewed diagonally from above. This is an oblique view of the corner portion between the vertical frame and the lower frame, viewed diagonally from below. 1A is a plan view of a corner water-stopping component and position adjustment component, FIG. 1B is a front view of the same, and FIG. 1A to 1C are cross-sectional views showing the steps of fitting the sash frame into the opening in the main body from the outside.

The following describes an embodiment of the present invention with reference to the drawings. Figures 1 to 5 show one embodiment of the building material for openings according to the present invention. This building material for openings is applied to sliding windows in wooden houses, and as shown in Figures 2 and 3, it comprises a sash frame 1 attached to a structural opening 7, an outer screen 8a and an inner screen 8b that are arranged inside the sash frame 1 in a sliding manner so that they can be opened and closed freely, and a screen door 10 that is arranged on the outside of the outer screen 8a and can slide along the upper and lower frames 9 and 4.

As shown in Figures 2 and 3, the sash frame 1 is composed of an upper frame 9, a lower frame 4, and left and right vertical frames 3, 3, all of which are made of aluminum shaped material. More specifically, the sash frame 1 is framed by butting the longitudinal end faces of the upper frame 9 and the lower frame 4 against the inner peripheral side faces of the upper and lower ends of the vertical frame 3 via rubber sealers 11 (see Figure 1), and screwing screws 12 inserted from the outer periphery of the vertical frame 3 into tapping holes 13 (see Figure 3) of the upper frame 9 and the lower frame 4. The sash frame 1 is a so-called semi-external frame, and fins 15 for fixing to the frame 14 are provided at the middle position in the indoor/outdoor direction, protruding toward the outer periphery.
The sash frame 1 has outer dimensions in the up-down and left-right directions that are smaller than the up-down and left-right dimensions of the structural opening 4, and when the sash frame 1 is fitted into the structural opening 4, as shown in Figures 1 to 3, a gap S is created between the left and right vertical frames 3, 3 and the side edges 7a of the structural opening 7, and between the upper frame 9 and the upper edge 7b of the structural opening 7.

As shown in Figures 1, 4 and 5, a corner water stopper and position adjustment part 2 is attached to the outer periphery of the corner between the vertical frame 3 and the bottom frame 4, which is closer to the interior than the fins 15 of the sash frame 1. The corner water stopper and position adjustment part 2 is integrally molded from absorbent rubber or resin, and has an exterior wall 16 that abuts against the interior side of the fins 15 of the sash frame 1, a bottom wall 17 that runs along the outer periphery of the bottom frame 4, a side wall 18 that abuts against the outer periphery of the vertical frame 3, and an interior wall 19 that abuts against the interior side of the bottom frame 4. The material of the corner water stopper and position adjustment part 2 is not limited, but can be rubber, PP, PE, etc.

As shown in Figure 3, the bottom wall 17 is in the form of a horizontal plate, with the lower end 4a of the lower frame 4 abutting the upper surface of the bottom wall 17 and the lower surface of the bottom wall 17 abutting the lower edge 7c of the main body opening 7, and the space between the upper surface of the bottom wall 17 and the lower surface of the lower frame 4 forming an area 5 for collecting water that leaks from the joint between the vertical frame 3 and the lower frame 4.
1, grooves 22 are formed on the inner peripheral surface of the side wall 18 to accommodate the protrusions 20 and screw heads 21 on the outer peripheral surface of the vertical frame 3, as well as grooves 24 that fit with protrusions 23 formed on the interior side of the vertical frame 3. A protrusion 25 is provided inside the indoor groove 24, which elastically deforms to press the protrusions 23 of the vertical frame 3 from the interior side, thereby fixing the corner water stopper and position adjustment part 2 in a braced state between the fins 15 of the vertical frame 3 and the protrusions 23 at the interior end. The corner water stopper and position adjustment part 2 is slid from the small opening at the bottom end of the vertical frame 3 and fitted into the vertical frame 3.
A plurality of elastic pieces 6a, 6b, 6c that protrude outward are provided at intervals in the indoor/outdoor directions on the outer peripheral side surface of the side wall 18. Before the sash frame 1 is inserted into the frame opening 7, each elastic piece 6a, 6b, 6c protrudes outward in a bow-like shape toward the outside of the room, as shown in Figures 4, 5, and 6, with the piece located closer to the outside protruding farther outward. In the example shown, three elastic pieces 6a, 6b, 6c are formed, with the elastic piece 6a on the indoor side protruding the least to the outer peripheral side, the elastic piece 6c on the outdoor side protruding the most to the outer peripheral side, and the elastic piece 6b in the middle having an intermediate height between them.

Fig. 7 shows the state when the sash frame 1 with the corner water stopper/position adjustment part 2 attached is inserted into the structural opening 7 from the outside of the room. As shown in Fig. 7(a), when the sash frame 1 is moved from the outside of the structural opening 7 to the inside of the room, the elastic piece 6a on the inside of the room is first pushed by the side edge 7a of the structural opening 7 and elastically deforms so as to fall to the outside of the room, as shown in Fig. 7(b). Next, as shown in Fig. 7(c), the middle elastic piece 6b is pushed by the side edge 7a of the structural opening 7 and elastically deforms so as to fall to the outside of the room. Finally, as shown in Fig. 7(d), the elastic piece 6c on the inside of the room is pushed by the side edge 7a of the structural opening 7 and elastically deforms so as to fall to the outside of the room.
As a result of the multiple elastic pieces 6a, 6b, 6c successively deforming in this manner, the gaps S between the left and right vertical frames 3, 3 and the side edges 7a of the structural opening 7 become the same size, so that the sash frame 1 is positioned at the center in the left-right direction of the structural opening 7. The elastic pieces 6a on the indoor side have a low protruding height, and those on the outdoor side have a higher protruding height, so that the resistance when fitting the sash frame 1 into the structural opening 7 is initially small and gradually increases as the sash frame 1 is moved toward the indoor side, so that the sash frame 1 can be fitted into the structural opening 7 smoothly and accurately.
Thereafter, just as in the case of installing a normal sash, it is checked whether the diagonal dimensions of the sash frame 1 are approximately the same and whether the sash frame 1 is twisted or tilted, and then the sash frame 1 is fixed to the main body 14 with screws not shown.

As described above, this opening building material has the corner water stopper and position adjustment part 2 attached to the outer periphery of the corner between the vertical frame 3 and the bottom frame 4 of the sash frame 1, so that it can prevent water leaking from the joint between the vertical frame 3 and the bottom frame 4 from infiltrating into the framework 14. That is, if water leaks from the joint between the vertical frame 3 and the bottom frame 4 due to poor application of the sealer 11 or deterioration over time, the water will accumulate in the space 5 between the upper surface of the bottom wall 17 of the corner water stopper and position adjustment part 2 and the lower surface of the bottom frame 4. Since the entire corner water stopper and position adjustment part 2 is made of a material that can absorb water, the water is absorbed by the bottom wall 17 of the part 2, etc., and the water does not infiltrate into the framework 14. The absorbed water will evaporate in time.
Conventionally, to prevent water leaking from the joint between the vertical frame 3 and the bottom frame 4 from seeping into the framework 14, a waterproof sheet is attached in advance to the corners so as to span the side edge 7a and the bottom edge 7c of the framework opening 7. This opening building material has the corner water-stopping part/position adjustment part 2 attached to the sash frame 1 as described above, so that water can be prevented from seeping into the framework 14 even if such a waterproof sheet is omitted.

In the above embodiment, the entire corner water stopper and position adjustment part 2 is made of a material that can absorb water, but it is also possible to form the entire part from a resin that does not absorb water, and to provide a partial water absorbing part by attaching a water absorbent sheet only to the part facing the joint between the vertical frame 3 and the bottom frame 4. Also, instead of providing a water absorbing part, a recess may be formed on the bottom wall 17 facing the joint between the vertical frame 3 and the bottom frame 4, and water that leaks from the joint between the vertical frame 3 and the bottom frame 4 may be collected in the recess.

As described above, this opening building material comprises a sash frame 1 and a corner water-stopping part (which also doubles as a position adjustment part) 2, and the corner water-stopping part 2 is provided on the outer periphery of the corner portion of the vertical frame 3 and bottom frame 4 of the sash frame 1 and is provided with a portion 5 for collecting water that leaks from the joint between the vertical frame 3 and bottom frame 4. Therefore, simply by fitting the sash frame 1 with the corner water-stopping part 2 attached into the structural opening 7 from the outside, it is possible to prevent water that leaks from the joint between the vertical frame 3 and bottom frame 4 from entering the structural body 14, thereby improving workability.
The corner water stop part 2 is provided with a water absorbing part facing the joint between the vertical frame 3 and the lower frame 4, so that water leaking from the joint between the vertical frame 3 and the lower frame 4 is absorbed by this part, and thus water can be reliably prevented from entering the main body 14 side.

In addition, this opening building material comprises a sash frame 1 and a position adjustment part (corner water stop part that also serves as a position adjustment part) 2, and the position adjustment part 2 is attached to the outer periphery side of the vertical frame 3 and has multiple elastic pieces 6a, 6b, 6c that protrude toward the outer periphery, spaced apart in the indoor-outdoor direction. Therefore, when the sash frame 1 is fitted into an opening in the structural body 7 from the outside, the elastic pieces 6a, 6b, 6c of the position adjustment part 2 elastically deform and press the side edge 7a of the opening in the structural body 7, thereby positioning the sash frame 1 at the center position in the left-right direction of the opening in the structural body 7, and because the elastic piece 6c on the outside side protrudes farther toward the outer periphery than the elastic piece 6a on the inside side, it is easy to fit the sash frame 1 into the opening in the structural body 7 from the outside, thereby improving workability.
The position adjustment part 2 has a part (side wall) 18 contacting the outer peripheral side surface of the vertical frame 3 and a part (bottom wall) 17 contacting the outer peripheral side surface of the horizontal frame (bottom frame) 4, and is fitted and attached by sliding from the small end of the vertical frame 3, so that the position adjustment part 2 can be easily attached after framing the sash frame 1 in the factory, and further, the position adjustment part 2 does not fall off even if the sash frame 1 is vertical, so that the position adjustment part 2 does not come off while the sash frame 1 is being transported.

The present invention is not limited to the above-described embodiments. The shape and material of the sash frame can be changed as appropriate. The position adjustment part only needs to have multiple elastic pieces that protrude toward the outer periphery and are spaced apart in the indoor/outdoor direction, and the shape and material of the elastic pieces can be changed as appropriate. The position adjustment part does not necessarily have to double as a corner water stop part, and a position adjustment part can be provided separately from the corner water stop part on the outer periphery side of the corner part between the vertical frame and the upper frame, or in the vertical middle part of the vertical frame. The present invention is not limited to sliding windows and can be applied to all types of windows.
