JP4548879B2 - Waterproof device for joint between vertical frame and bottom frame of heat insulating sash - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to a vertical frame for a heat insulating sash constructed by interposing an intermediate material made of a low thermal conductivity material (generally, synthetic resin) in an intermediate portion in the expected direction of each of the metal upper and lower frames and the left and right vertical frames. The present invention relates to a waterproof device for a joint portion between the lower frame and the lower frame.
[0002]
[Prior art]
The vertical frame and the lower frame (same for the upper frame) constituting the heat insulating sash are low heat interposed between metal indoor and outdoor frame materials (frame materials constituting the indoor side frame and the outdoor side frame). The interposing material made of a conductive material is configured to be held (clamped) by a holding piece provided on the opposite surface side of the indoor / outdoor frame material. There is a gap between the pieces, so when the end face of the lower frame is abutted against the inner surface of the vertical frame through the sheet-like water-stopping material and both frames are enameled, the water-stopping material absorbs the gap completely. (If the water-stopping material is a convex part, the water-stopping material does not reliably perform the water-stopping function. Enters the building.
[0003]
[Problems to be solved by the invention]
For this reason, as described in Japanese Patent Publication No. 7-103752, in order to fill the gap generated between the holding pieces inside and outside, the surface and the surface of the holding piece are placed on the portion of the interstitial material corresponding to the gap. A built-up portion is provided so that no gap is generated by the built-up portion.
[0004]
However, to obtain a structure in which each part of the vertical frame including the built-up part of the interposed piece is brought into contact with the end surface of the lower frame through the water-stopping material (same surface), the vertical frame is configured. Assembling accuracy between the indoor and outdoor frame material and the interposing material is difficult, and as a result, a gap is created between the water stop material (the lower frame end surface through the interposing material) and the interposing material. May not be achieved.
[0005]
This is considered to be caused by designing the surfaces of the indoor and outdoor frame materials and the interposition materials to be flush with each other from the beginning.
[0006]
The present invention was devised for the purpose of eliminating practical disadvantages that are likely to occur from such prior art, and provides a heat insulating sash that does not allow rainwater to enter through the joint between the vertical frame and the lower frame. It was created for the purpose.
[0007]
[Means for Solving the Problems]
It is composed of a vertical frame and a lower frame that are sandwiched between gripping pieces provided on opposite sides of the frame material inside and outside the frame material between the frame materials inside and outside the metal, At the joint between the vertical frame and the lower frame of the heat insulating sash, where the end face of the lower frame abuts the inner surface of the vertical frame with a sheet-like water stop material on the same surface in the direction of finding, A part of the interposing material between the inner and outer frame members protrudes from between the holding portions of the indoor and outdoor frame members of the vertical frame and is fitted into the water stop material.

【Example】
The drawings show an embodiment of a waterproof device for a joint between a vertical frame and a lower frame of a heat insulating sash according to the present invention, FIG. 1 is a perspective view, and FIG.
[0009]
In the figure, 1 is one vertical frame that constitutes a heat insulating sash together with an upper frame (not shown) and another vertical frame, and 2 is a lower frame.
[0010]
The vertical frame 1 has an interposition material 1c made of a low thermal conductivity material interposed between a metal indoor side frame material 1a and a metal outdoor side frame material 1b, and the interposition material 1c is attached to the indoor / outdoor frame. A pair of inner and outer gripping pieces 3, 3 '. It is constructed by holding 3 and 3 '.
[0011]
The intervention material 1c is formed of a hollow body provided with a pair of grooves 4, 4.4 ', 4' along the longitudinal direction (vertical direction) on both the inside and outside directions perpendicular to the indoor / outdoor direction of the vertical frame 1, In the grooves 4, 4.4 ', 4', the holding part pieces 3, 3 '. 3, 3 'protruding edges 3a, 3'a. 3a and 3'a are engaged and press-fitted, so-called caulking is stopped, and the indoor and outdoor frame members 1a and 1b and the interposing material 1c are integrated with each other to form the vertical frame 1, and the inner holding member that holds the interposing member 1c. Surfaces 3A and 3A of the pieces 3 and 3 are positioned on the same surface as the inner surfaces 1a 'and 1b' of the indoor and outdoor frame members 1a and 1b, and the holding piece 3 on the inner surfaces 1a 'and 1b' side. , 3 (the inner holding part piece 3 of the indoor side frame member 1a and the inner holding part piece 3 of the indoor side frame member 1b) are disposed between the holding part pieces 3 and 3 (surface 3A) as shown in FIG. , 3A and the inner surfaces 1a ′, 1b ′). (The sheet-like water blocking material 4 is protruded to such an extent that the protrusion amount can be absorbed).
[0012]
The lower frame 2 is provided with a pair of upper and lower grooves 5, 5 ′ along the longitudinal direction on opposite surfaces of the metal indoor side frame member 2 a and the metal outdoor side frame member 2 b, and the grooves 5, 5 are provided. ′ Is engaged with end portions along the longitudinal direction of a pair of upper and lower bridge members (intervening members) 6 and 6 ′ made of a low heat conductive material, and the indoor and outdoor frame members 2 a and 2 b and the upper and lower bridge members 6 are engaged. , 6 'are assembled to each other, and the surface (upper surface) of the piece 2a' of the indoor side frame member 2a and the piece 2b 'of the outdoor side frame member 2b constituting the upper groove 5 and between the surfaces The partial surfaces of the upper bridge member 6 are inclined so as to be coplanar with each other to form an inclined surface as the lower frame 2, that is, an inclined surface a inclined so as to gradually decrease from the indoor side toward the outdoor side, The retention of water such as rain water and dew condensation water at the joint between the two frame members 2a and 2b is prevented, and the water prevents the joint (inclined surface a). Flip and are so as not to intrude into the building.
[0013]
The heat insulating sash of the embodiment is formed by assembling the vertical frame 1 and the lower frame 2, the upper frame and the other vertical frame, which are not shown in the figure, by mutually joining the seals with the upper frame and the lower frame 2 inside. The end surface of the lower frame 2 is abutted against the inner surface (the inner surfaces 1a 'and 1b' of the frame materials 1a and 1b) via the sheet-like water blocking material 8 and is tapped using the tapping groove 9 provided in the lower frame 2. By tightening with screws, the protruding portion 10 of the interposing material 1c that protrudes from the inner surface through the gap between the holding piece pieces 3 and 3 on the water-stopping material 8 is partly elastic. It is inserted using deformation.
[0014]
【The invention's effect】
Since the present invention is configured as described above, it prevents the gap between the vertical frame side interposing material and the water stop material at the joint between the vertical frame and the lower frame, and prevents rainwater between these two materials. Insulation sash that prevents intrusion and has no inconvenience in water performance can be provided.
