Abstract

PROBLEM TO BE SOLVED: To provide a heat insulating sash preventing rainwater from entering therein through an interposing material and a cut-off material and having nothing wrong in flashing structure by preventing any clearance from formed between the interposing material and the cut-off material in a jamb side in the joining part between the jamb and a sill. SOLUTION: This joining part between the jamb 1 and the sill 2 of the heat insulating sash is so constituted that the interposing material 1c composed.of a low-heat conduction material comprises the jamb 1 and the sill 2 clamped between clamping pieces 3, 3'. 3, 3' provided in opposite face sides of indoor/ outdoor frame materials between the metal indoor/outdoor frame materials 1a, 1b and the end face of the sill 2 abuts on the inside face of the jamb 1 via the sheet type cut-off material 8 with respective parts set flush in the depth direction. A part of the interposing material 1c between the indoor/outdoor frame materials 1a, 1b of the jamb 1 is projected between clamping pieces 3, 3 of the indoor/outdoor frame materials 1a, 1b and fitted into the cut-off material 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an intermediate material in a prospective direction of a metal upper and lower frame and left and right vertical frames, and an interposition material made of a material having low thermal conductivity (generally, synthetic resin) interposed therebetween. The present invention relates to a waterproof device for connecting a vertical frame and a lower frame of a heat insulating sash.

[0002]

2. Description of the Related Art A vertical frame and a lower frame (same for an upper frame) constituting the heat insulating sash are formed between metal indoor and outdoor frame materials (frame materials constituting an indoor side frame and an outdoor side frame). An interposer made of a low heat conductive material interposed between the indoor and outdoor frames is clamped (clamped) by the clamping pieces provided on the opposing surfaces of the frame material inside and outside. A gap is created between the holding parts of the frame material, so that when the end surface of the lower frame is abutted against the inner surface of the vertical frame via the sheet-like water-stop material and both frames are joined together, the water-stop material becomes The gap cannot be completely absorbed (the water-stopping material does not reliably perform the water-stopping function if the contact partner is a convex portion, and does not perform the water-stopping function because the concave portion is deformed and does not fill the concave portion). Rainwater enters the building through the gap.

[0003]

SUMMARY OF THE INVENTION
As described in Japanese Patent No. 103752, in order to fill the gap formed between the holding parts inside and outside of the room, a built-up portion which is flush with the surface of the holding piece is provided in a portion of the interposition material which abuts the gap. It is provided so that no gap is formed by the overlay portion.

However, in order to obtain a structure in which each part of the vertical frame including the overlaying portion of the interposition piece is brought into flush contact with the end face of the lower frame via the waterproof material, it is necessary to use a vertical Difficulty in assembling accuracy between the indoor and outdoor frame materials and interposer that constitute the frame,
As a result, a gap is formed between the waterproofing material (the end face of the lower frame) and the intervening material, and the intended purpose may not be achieved.

[0005] This is considered to be caused by designing the inside and outside of the frame material and the interposer so that the surfaces thereof are flush with each other from the beginning.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate practical disadvantages which are likely to occur from the prior art, and an insulating sash which does not allow rainwater to penetrate through a junction between a vertical frame and a lower frame. It was created for the purpose of providing.

Means for Solving the Problems A vertical member in which an interposed material made of a low heat conductive material is sandwiched between metal frames inside and outside a frame by a clip portion provided on the opposite surface side of the frame material between the room and the outside. A vertical frame and a lower frame of a heat insulating sash, which are constituted by a frame and a lower frame, and each end of the lower frame abuts on an inner surface of the vertical frame via a sheet-like water-stopping material with the respective parts abutting on the same plane in a finding direction. A part of the interposition material between the indoor and outdoor frame materials of the vertical frame is projected from between the holding portions of the indoor and outdoor frame materials of the vertical frame and fitted into the waterproof material.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a waterproofing device for a joint between a vertical frame and a lower frame of a heat insulating sash according to the present invention.
FIG. 2 is a sectional view of a main part.

In the figure, reference numeral 1 denotes one vertical frame constituting an insulating sash together with an upper frame not shown and other vertical frames, and 2 denotes a lower frame.

The vertical frame 1 has an interposer 1 made of a low heat conductive material between a metal indoor frame 1a and a metal outdoor frame 1b.
c, and the intervening material 1c is
a, 1b, a pair of inner and outer clamping pieces 3, 3 '. 3, 3 '.

The interposition material 1c is a hollow body provided with a pair of grooves 4, 4.4 ', 4' along the longitudinal direction (longitudinal direction) on both sides of the vertical frame 1 in the inside and outside directions perpendicular to the indoor and outside directions. , And the holding portions 3, 3 ′. 3,
3 'protruding edges 3a, 3'a. 3a, 3'a are engaged and press-fitted, so-called caulking, and the indoor and outdoor frame members 1a, 1b and the
c are integrated with each other to form the vertical frame 1, and the surfaces 3A, 3A of the inner holding pieces 3, 3 for holding the interposition material 1c are inner surfaces 1a ', 1b' of the indoor and outdoor frame materials 1a, 1b. Between the holding parts 3 and 3 (the inner holding part 3 of the indoor frame member 1a and the inner holding part 3 of the indoor frame member 1b) on the inner surfaces 1a 'and 1b'. As shown in FIG. 2, the intervening material 1c is sandwiched between the holding pieces 3 and 3 (surfaces 3A, 3A and inner surface 1a).
', 1b') to form a protruding portion 10.
(The sheet-like water-stopping material 4 is protruded to such an extent that the amount of protrusion can be absorbed).

The lower frame 2 is provided with a pair of upper and lower grooves 5 and 5 'along the longitudinal direction on opposing surfaces of a metal indoor frame material 2a and a metal outdoor frame material 2b, respectively. A pair of upper and lower bridge materials (intervening materials) made of low thermal conductive material at 5,5 '
The upper and lower frame members 2a and 2b and the upper and lower bridge members 6 and 6 'are assembled together by engaging the ends along the longitudinal direction of the upper and lower frames 5 and 6'. The part 2a 'of the indoor frame member 2a and the part 2b' of the outdoor frame member 2b
The surface (upper surface) of the upper bridge member 6 and the partial surfaces of the upper bridge material 6 existing between the surfaces are inclined so as to be flush with each other to form the lower frame 2
, That is, an inclined surface a which is inclined so as to gradually decrease from the indoor side to the outdoor side, and both frame members 2a,
Water such as rainwater and dew condensation is prevented from staying at the joint of 2b, and water is prevented from entering the building through the joint (inclined surface a).

The heat insulating sash according to the embodiment comprises a vertical frame 1 and a lower frame 2, an upper frame and other vertical frames not shown, and an upper frame and a lower frame 2.
