Description

The present invention relates to building materials for openings that have thermal insulation properties.

Conventionally, building materials for openings have been known that use insulating profiles with a composite structure of aluminum and resin for the frame.

In view of the above-mentioned circumstances, the present invention aims to provide an easy-to-use building material for openings.

In order to achieve the above object, the opening building material according to the invention described in claim 1 comprises a vertical frame, a horizontal frame and a water-stopping material, the horizontal frame consisting of an exterior shape, an interior shape and a bridge material connecting the exterior shape and the interior shape, the longitudinal end face abutting against the inner peripheral side surface of the vertical frame via a sealer, the exterior shape and the interior shape being screwed to the vertical frame, the water-stopping material being provided in the longitudinal direction of the horizontal frame from a position where it abuts against the sealer on the outer periphery of the horizontal frame, and being inserted into the cut-out portion between the exterior shape and the interior shape and abutting against the sealer, the exterior shape, the interior shape and the bridge material, and when the bridge material shrinks the gap between the longitudinal end face of the bridge material and the sealer is sealed by the water-stopping material.

The opening building material according to the invention described in claim 1 comprises a vertical frame, a horizontal frame and a water-stopping material. The horizontal frame is composed of an exterior shape, an interior shape and a bridge material connecting the exterior shape and the interior shape. The longitudinal end face abuts against the inner peripheral side of the vertical frame via a sealer, and the exterior shape and the interior shape are screwed to the vertical frame. The water-stopping material is provided in the longitudinal direction of the horizontal frame from a position where it abuts against the sealer on the outer periphery of the horizontal frame, and is inserted into the cut-out portion between the exterior shape and the interior shape to abut against the sealer, the exterior shape, the interior shape and the bridge material. When the bridge material shrinks, the gap between the longitudinal end face of the bridge material and the sealer is filled with the water-stopping material, thereby obtaining insulating performance and being easy to use because the water-stopping material can prevent water leakage into the structure even when the bridge material shrinks.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 5 show a first embodiment of the opening construction material of the present invention. This opening construction material is applied to a sliding window for a house, and as shown in Figures 1 and 2, it comprises a frame 10 attached to a structural opening 9, and an outer screen 11a and an inner screen 11b housed in the frame 10 in a sliding manner so as to be freely opened and closed.
The frame 10 is constructed by framing an upper frame 12, a lower frame 2, and left and right vertical frames 1, 1 in a rectangular shape. The outer screen 11a and the inner screen 11b are constructed by assembling an upper frame 13, a lower frame 14, a door end frame 15, and a joint frame 16, and fitting glass (double glazing) 17 inside them.

As shown in FIG. 1, the lower frame 2 is an insulating material consisting of an exterior shape 5 and an interior shape 6 made of an aluminum alloy extrusion, and a bridge material 7 connecting the exterior shape 5 and the interior shape 6. The exterior shape 5 and the interior shape 6 each have a tapping hole 18. The bridge material 7 is made of a material with insulating properties and blocks heat transfer between the exterior shape 5 and the interior shape 6. The lower frame 2 is a so-called cast-type insulating material, in which the exterior shape 5 and the interior shape 6 are originally molded together while connected, and a resin (e.g., polyurethane resin) that is the material for the bridge material 7 is injected into a bridge material injection groove formed along the longitudinal direction in the middle part of the shape in the indoor/outdoor direction, and after the resin hardens, the bottom wall of the bridge material injection groove is cut from the outer periphery to separate the exterior shape 5 and the interior shape 6 (reference numeral 19 in FIG. 3 indicates the separation part).

The vertical frame 1 has a rubber sheet-like sealant 8 (see Figures 2 and 4) attached to the inner circumferential side of the upper and lower ends, and the lower frame 2, as shown in Figures 1 and 2, abuts its longitudinal end face against the inner circumferential side of the vertical frame 1 via the sealant 8, and is connected and fixed to the vertical frame 1 by threading screws 20 inserted from the side of the vertical frame 1 into tapping holes 18 in the exterior shape member 5 and the interior shape member 6.

As shown in Figures 1 and 2, a packing (water-stopping material) 3 and a pressing material 21 that presses the packing 3 from the outer periphery are provided on the outer periphery of the longitudinal end of the lower frame 2. The packing 3 is made of a flexible material such as rubber or soft resin, and as shown in Figure 1, it is pressed across the indoor end of the outer periphery side of the outdoor-side shape member 5, the outdoor end of the outer periphery side of the indoor-side shape member 6, and the outer periphery side of the bridge material 7 exposed from the separation part 19 between the outdoor-side shape member 5 and the indoor-side shape member 6. As shown in Figure 2, the packing 3 is provided at a predetermined length (e.g., about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it abuts against the sealer 8 of the vertical frame 1.
The clamping member 21 is formed by bending a metal plate such as stainless steel into a crank shape, and the elevated exterior piece 22 holds down the gasket 3 from the outer periphery, while the interior piece 23 abuts against the underside of the interior profile 6 and is fixed in place with screws 24 from below.
As shown in Figure 3(a), before being attached to the lower frame 2, the packing 3 is in the shape of a block with a substantially square cross section, and is attached by adhering it to the exterior piece 22 of the clamping member 21 with double-sided tape or the like. Then, when a screw 24 passed through the interior piece 23 of the clamping member 21 is screwed into a female threaded hole 25 formed in the interior shape member 6 and tightened, the packing 3 is pressed by the exterior piece 22 of the clamping member 21, compressed in the vertical direction, and expands around, so that the top surface of the packing 3 is pressed against the outer peripheral side surfaces of the exterior shape member 5, the bridge member 7, and the interior shape member 6, and the longitudinal end faces are pressed against the sealer 8.

As shown in FIG. 1, the upper frame 12 is also an insulating member made of an exterior shape 26 and an interior shape 27 made of an aluminum alloy extrusion, and a resin bridge member 28 that connects the exterior shape 26 and the interior shape 27. However, the upper frame 12 does not have a gasket 3 like the lower frame 2.

Initially, the longitudinal end faces of the bridge material 7 of the bottom frame 2, together with the exterior shape material 5 and the interior shape material 6, abut against the sealer 8 on the inner side of the vertical frame 1 (see Figure 4(a)). However, over time, the bridge material 7 may shrink due to differences in the amount of thermal expansion between aluminum and resin, and when the bridge material 7 of the bottom frame 2 shrinks, the longitudinal end faces of the bridge material 7 separate from the sealer 8 on the inner side of the vertical frame 1, creating a gap 29 (see Figure 5(a)). If no measures are taken, rainwater that has infiltrated the top surface of the bottom frame 2 may flow down through the gap 29 and infiltrate into the main structure.
As shown in Figures 5(a) and (b), in this opening building material, a gasket 3 is provided on the outer periphery of the longitudinal end of the bottom frame 2, and the gasket 3 is pressed against the bridge material 7 exposed from the separation part 19 between the exterior shape member 5 and the interior shape member 6. The gasket 3 also seals the separation part 19 between the exterior shape member 5 and the interior shape member 6. In addition, the longitudinal end face of the gasket 3 abuts against the sealer 8 on the inner peripheral side face of the vertical frame 1. Therefore, even if the bridge material 7 shrinks and a gap 29 occurs between the longitudinal end face of the bridge material 7 and the sealer 8 on the inner peripheral side face of the vertical frame 1, the gap 29 is sealed on the outer periphery by the gasket 3, and therefore water leakage to the main body 30 side can be prevented.
Moreover, this opening building material has a pressing material 21 for pressing the packing 3 from the outer periphery side, and the packing 3 is crushed by the pressing material 21, so that the gap 29 caused by the shrinkage of the bridge material 7 can be stably closed and water leakage to the framework 30 can be reliably prevented.

As shown in Figure 6, the packing 3 can be formed in two layers, upper and lower, with the upper packing 3a adhered to the outer peripheral side surface of the lower frame 2 with double-sided tape or the like, and the lower packing 3b adhered to the upper surface of the clamping material 21 with double-sided tape or the like.
Also, the packing 3 and the retaining member 21 can be provided on the inner peripheral side (top surface side) of the lower frame 2 instead of on the outer peripheral side of the lower frame 2. In this case, the packing 3 and the retaining member 21 can be hidden by a resin cover 31 (see FIG. 1) or a stopper part 32 (see FIG. 2) attached to the top surface of the lower frame 2.

Figures 7 to 10 show a second embodiment of the opening construction material of the present invention. As shown in Figures 7 to 9, the opening construction material of this embodiment has a wet sealant (unformed sealant) 4 applied to the inner periphery of both longitudinal ends of the lower frame 2 instead of providing a packing 3 as a waterproofing material. As shown in Figure 7, the sealant 4 is bonded across the indoor end of the inner periphery side (top surface) of the outdoor exterior shape member 5, the inner periphery side of the bridge material 7, and the outdoor end of the inner periphery side of the indoor interior shape member 6. As shown in Figure 8, the sealant 4 is provided for a predetermined length (e.g., about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it abuts against the sealer 8 of the vertical frame 1.

10(a), the bridge material 7, together with the exterior shape member 5 and the interior shape member 6, initially has its longitudinal end face in contact with the sealer 8 of the vertical frame 1. The sealant 4 is bonded across the inner peripheral side surface (top surface) of the exterior shape member 5, the bridge material 7, and the interior shape member 6 as described above, and its longitudinal end is bonded to the sealer 8 of the vertical frame 1.
10(b) shows a state in which the bridge material 7 has shrunk, causing a gap 29 to appear between the longitudinal end face of the bridge material 7 and the sealer 8 of the vertical frame 1. Even if the bridge material 7 shrinks in this way, the sealant 4 remains bonded to the sealer 8, and the gap 29 between the bridge material 7 and the sealer 8 is blocked on the inner periphery by the sealant 4, preventing water from leaking into the main body 30.

Figures 11 to 14 show a third embodiment of the opening construction material of the present invention. As shown in Figures 11 to 13, the opening construction material of this embodiment has a sealant 4 as a water-stopping material provided on the outer periphery of the lower frame 2. As shown in Figure 11, the sealant 4 is bonded across the interior end of the outer periphery side (lower surface) of the exterior shape member 5, the outer periphery side of the bridge member 7, and the exterior end of the outer periphery side of the interior shape member 6. As shown in Figure 12, the sealant 4 is provided for a predetermined length (e.g., about 3 cm) along the longitudinal direction of the lower frame 2 from the position where it abuts against the sealer 8 of the vertical frame 1.

14(a), the longitudinal end faces of the bridge material 7, together with the exterior shape member 5 and the interior shape member 6, are initially in contact with the sealer 8 of the vertical frame 1. The sealant 4 is bonded across the outer peripheral side faces (undersides) of the exterior shape member 5, the bridge material 7, and the interior shape member 6 as described above, and its longitudinal end is bonded to the sealer 8 of the vertical frame 1.
14(b) shows a state in which the bridge material 7 has shrunk, causing a gap 29 to appear between the longitudinal end face of the bridge material 7 and the sealer 8 of the vertical frame 1. Even if the bridge material 7 shrinks in this way, the sealant 4 remains bonded to the sealer 8, and the gap 29 between the bridge material 7 and the sealer 8 is blocked by the sealant 4 on the outer periphery, preventing water from leaking into the main body 30.

As described above, this opening building material (first to third embodiments) comprises a vertical frame 1, a horizontal frame (bottom frame) 2, and water-stopping materials (packing, sealing materials) 3, 4. The horizontal frame 2 is made up of an exterior shape member 5, an interior shape member 6, and a bridge material 7 connecting the exterior shape member 5 and the interior shape member 6. The longitudinal end face is in contact with the inner peripheral side surface of the vertical frame 1 via a sealer 8, and the exterior shape member 5 and the interior shape member 6 are screwed to the vertical frame 1. The water-stopping materials 3, 4 are attached to the outer or inner peripheral side of the horizontal frame 2. The bridge material 7 is provided in the longitudinal direction of the horizontal frame 2 from a position abutting against the sealer 8 on the side, and abuts against the sealer 8, the exterior shape 5, the interior shape 6, and the bridge material 7. When the bridge material 7 shrinks, a gap 29 between the longitudinal end face of the bridge material 7 and the sealer 8 is blocked by the water-stopping materials 3, 4, so that heat insulating performance is obtained and the water-stopping materials 3, 4 can prevent water leakage into the main body 30 even when the bridge material 7 shrinks, making it easy to use.
In the first embodiment of the opening building material, the water-stopping material 3 is a gasket and has a clamping material 21 that presses the gasket 3 from the outer or inner side of the horizontal frame 2, so that the gap 29 created by the shrinkage of the bridge material 7 can be stably sealed and water leakage into the main body 30 can be reliably prevented.
In the second and third embodiments of the building materials for openings, the water-stopping material 4 is an amorphous sealing material, so water leakage into the main body 30 can be prevented simply by applying the amorphous sealing material 4 to specified locations on the frame 10, making it low cost.
Furthermore, in this opening building material (first to third embodiments), the water-stopping materials 3, 4 are provided in an area of a predetermined length from the sealer 8 in the longitudinal direction of the horizontal frame 2, so that the gap 29 caused by shrinkage of the bridge material 7 can be reliably prevented by the water-stopping materials 3, 4, and costs can be reduced compared to the case where the water-stopping materials are provided over the entire longitudinal length of the horizontal frame 2.

The present invention is not limited to the above-described embodiment. The cross-sectional shapes of the exterior and interior shapes can be changed as appropriate. The shape and material of the water-stopping material can be changed as appropriate. The water-stopping material only needs to be installed to close the gap that is created when the bridge material shrinks, and the specific position and installation method can be changed as appropriate. The vertical frame can be a mullion, and the horizontal frame can be a blind. The present invention can be applied not only to sliding windows, but also to all opening building materials such as fixed windows, sliding windows, entrance doors, back doors, and curtain walls.
