Abstract

PURPOSE: To improve the constructing efficiency of sealing, by a method wherein a long-sized sealing member, of which the width is larger than that of a space to be sealed, made of a resilient synthetic resin with a deterioration-resistant property, is forcibly fitted into the space between a flashing member and a sash frame, along the whole periphery thereof. CONSTITUTION: A sealing member 11 is pressed between a flashing member 3 and a sash frame 4 when forcibly fitted into a space S to be sealed, and hence the space S is watertightly sealed. The sealing member 11 does not need drying, though a conventional sealing member made of a fluid material needs drying, and hence working hours are shortened. The sealing member 11 is integrally backed with a rigid form- holding member 13, and hence the member 11 is prevented from being deformed. The sealing member 11 is held by fixing-pieces 15, through the holding member 13, and hence the member 11 is prevented from slipping off because of vibration or the like at the time when a glazed slide sash 6 is opened or shut. Furthermore, the sealing member 11 is made of a deterioration-resistant material having a water-proof property and an ozone-proof property, and hence a sealing function is displayed stably and surely. In this way, working efficiency can be improved and watertightness can be surely maintained for a long period of time.

To ensure that the entire space S to be sealed is evenly filled,
It is formed corresponding to the largest width of the sealed space S.
Specifically, the seal member 11 has a width larger than the maximum width of the sealed space S at the mounting position by a predetermined dimension, as indicated by a chain double-dashed line in FIG. 6 As indicated by the solid line, it is elastically compressed to the same width as the space S to be sealed, and elastically repulsive force of the compressed portion h elastically contacts the opening 1a and the peripheral surface of the sash 4 and is held in a fixed position. In addition, it has a predetermined sealing property. The compressed amount h is set so that the seal member 11 can be pressed into the minimum width portion of the sealed space S and that the seal member 11 can be held by the elastic repulsion force in the maximum width portion.

The material of the seal member 11 includes weather resistance,
Any material can be used as long as it is a synthetic resin or synthetic rubber having deterioration resistance such as ozone resistance. For example, ethylene propylene rubber (EPDM), hard polyvinyl chloride (PVC), etc. It is preferable from the viewpoint of excellent properties and ozone resistance. The sealing member 11 extrudes, for example, by extrusion molding a long product having the same cross-sectional shape as that of FIG. 3, and the positions of the long products corresponding to the four corners of the sealed space S are set to approximately 90 degrees. It is manufactured by bending and joining both ends together with an adhesive or the like.

The shape retaining member 13 is made of a hard material, and as shown in FIGS. 3 and 4, the seal member 11 is formed.

The fixing piece 15, which is composed of 7 in a state in which one side is in close contact with the sash 4 circumferential surface of the sealed space S and the other side is in close contact with the outer side surface of the shape holding member 13 attached to the sealed space S, , The sash 4 is screwed and fixed at a predetermined position, the movement of the seal member 11 to the outdoor O side is restricted through the shape holding member 13, and the seal member 11 is fixed at a predetermined position in the sealed space S. ing. The fixed piece 15 may be formed in the shape of an integral angle plate having a horizontally long rectangular shape corresponding to the front shape of the seal member 11, or
The seal member 11 may be divided into four straight angle plate shapes that support and fix the upper and lower sides and the left and right sides of the seal member 11.

In this embodiment, the seal member 11 is
Is arranged from the room I side of the sealed space S to the room O side thereof. Here, FIG. 7 is a cross-sectional view showing another example of the window around seal structure of the building of the present invention, and the seal member 11 of the present embodiment, as shown in FIG. May be arranged in two steps from the outside to the outdoor O side to improve the sealing property. In this way, the plurality of seal members 11
However, the sealed space S is watertightly filled and sealed in a multi-stage manner, and rainwater and the like can be more effectively prevented from entering the room I from the outdoor O through the sealed space S. In this case, preferably, the other side surface of the outdoor O-side seal member 11 is brought into contact with the shape retaining member 13 attached to the indoor I-side seal member 11.

Next, the operation of the window-surrounding structure for a building according to the present embodiment constructed as described above will be described with reference to FIGS. 2 and 6.

Becomes

Further, since the fixing member 15 of the fixing means supports the sealing member 11 via the shape holding member 13 and fixes it in a fixed position in the sealed space S, the sealing member 11 fixes the inside of the sealing space S. It becomes impossible to move from the position to the outdoor O side. Therefore, due to the vibration when the glass door 6 is opened and closed,
There is no problem that the seal member 11 is displaced and falls off.

Furthermore, since the seal member 11 is made of a material having weather resistance and deterioration resistance such as ozone resistance,
It has resistance to physical or chemical deterioration due to vibration, environmental conditions, etc., and stably and reliably exhibits its original sealing function.

3 is included.

Therefore, in the above embodiment, the seal member 1 is used.
When 1 is pressed into the sealed space S, the seal member 11
It is compressed to the width of the sealed space S and is held in the sealed space S by its elastic repulsion. Thereby, the seal member 11 fills and seals the sealed space S in a watertight manner, and prevents rainwater and the like from entering the room I from the outside O through the sealed space S into the room I. Here, since the seal member 11 has a fixed shape and is press-fitted into the sealed space S, the sealed space S like the sealing materials 101 and 103 made of a fluid material.
It does not require drying at the time of construction, and the working time for disposing the seal member 11 is shortened. As a result, the work efficiency in the window construction can be improved and the construction period can be shortened. Moreover, by fixing the seal member 11 at a fixed position in the sealed space S by the fixing means 15 and 17, the seal member 11 becomes immovable in the seal space S. Therefore, the seal member 11 will not be displaced due to vibration or the like when the window or the like is opened or closed. As a result, the seal member 11 can prevent rain leakage from around the window in a stable and reliable manner. Further, since the seal member 11 is formed of a deterioration resistant material, it has resistance to physical or chemical deterioration due to vibration, environmental conditions and the like. as a result,
It is possible to prevent problems such as cracks due to aging and the like, and prevent rain leakage by the seal member 11 stably and reliably for a long period of time.

Further, at the time of press-fitting the seal member 11 into the sealed space S, the hard shape retaining member 13 supports the flexible seal member 11 and prevents its deformation in the thickness direction and the width direction. Then, the seal member 11 is held in a constant shape corresponding to the sealed space S. Therefore, for example, by pressing two spaced positions of the shape retaining member 13 toward the sealed space S, it becomes possible to press-fit the sealing member 11 into the sealed space S collectively. as a result,
The press-fitting work of the seal member 11 into the sealed space S can be smoothly and easily performed, the work efficiency in the window surrounding work can be further improved, and the work period can be further shortened.

Further, the plurality of sealing members 11 multi-stagely fill and seal the sealed space S in a watertight manner to prevent rainwater and the like from entering the room I from the outside O through the sealed space S into the room I. . As a result, the seal member 11 can prevent rain leakage from around the window more stably and reliably.

A shape-retaining member made of a hard material for prevention is provided. Therefore, at the time of press-fitting the seal member into the sealed space, the hard shape retaining member supports the flexible seal member and prevents its deformation in the thickness direction and the width direction to prevent the seal member from being covered. It is kept in a fixed shape corresponding to the seal space. So, for example,
By pressing the two spaced-apart positions of the shape maintaining member toward the sealed space, it becomes possible to press-fit the sealing members together into the sealed space. As a result, the work of press-fitting the seal member into the sealed space can be smoothly and easily performed, the work efficiency in the window-surrounding work can be further improved, and the work period can be further shortened.

According to a third aspect of the present invention, in the first aspect of the invention, a plurality of the seal members are arranged from the indoor side to the outdoor side of the sealed space. Therefore, the plurality of sealing members watertightly fill and seal the sealed space, and prevent rainwater and the like from entering the room from the outside through the sealed space into the room. As a result, the seal member
It is possible to prevent rain leakage from around the window more stably and reliably.

According to a fourth aspect of the invention, in the first aspect of the invention, the sealing member is formed in a hollow shape. Therefore, the hollow seal member has greater flexibility, and is easily elastically deformed during the press-fitting operation into the sealed space to further facilitate the press-fitting operation. As a result, it is possible to further improve the work efficiency in the window surrounding construction and further shorten the construction period. Further, since the sealing member is hollow, the weight can be reduced and the material yield at the time of manufacturing can be improved.

According to a fifth aspect of the present invention, in the first aspect of the present invention, the seal member is formed on both sides in the width direction with a lip shape inclined from the indoor side to the outdoor side, and the opening of the sealed space and the sash peripheral surface are formed. It has an elastic contact part that elastically contacts with.
Therefore, since the elastic contact portion provided on the seal member has a lip shape that inclines from the indoor side to the outdoor side, when the sealing member is press-fitted into the sealed space, the seal member is easily deformed from the indoor side to the outdoor side, and the press-fitting is performed. Make the work easier. After the press-fitting, the opening and the side surface of the sash are elastically contacted in a state of inclining to the outdoor side, and the movement of the seal member to the outdoor side is regulated. As a result, the work efficiency in the window construction can be further improved, and the construction period can be further shortened.
It is possible to effectively prevent the seal member from moving from the fixed position, and to prevent rain leakage from around the window in a more stable and reliable manner.

According to a sixth aspect of the present invention, in the second aspect of the present invention, the shape retaining member is made of a hard synthetic resin and integrally molded with the seal member. Since the shape retaining member made of hard synthetic resin is integrally molded with the sealing member made of synthetic resin, both of them can be simultaneously manufactured by coextrusion molding or the like. As a result, the production efficiency can be improved as compared with the case where these are separately manufactured and joined.
