Description

  The present invention relates to a fitting that supports a multi-layer panel inside a frame member.

  For example, in fittings such as sliding windows and sliding windows, shoji screens that accommodate and support glass plates are supported openably inside the frame of the building by opening grooves formed in the inner peripheral surface of the frame frame. The configuration is used. In fittings that do not open and close, such as fitting windows, the shoji is fitted and killed inside the frame, or the glass plate is supported by the opening groove formed on the inner peripheral surface of the frame fixed to the building frame. Is used.

  When this kind of fitting is fireproof, it is required to have a fireproof performance capable of preventing the passage of flames and heat indoors and outdoors by ensuring a closed state for a certain time or more during a fire. However, aluminum used in many frame and frame bodies for windows softens or melts when exposed to high temperatures for a long time. Therefore, when the opening groove for accommodating and supporting the peripheral portion of the glass plate is softened, the glass plate may fall in the out-of-plane direction and a large through hole may be formed.

  In order to solve this problem, a reinforcing material made of metal with higher heat resistance such as steel or stainless steel is inserted into the opening groove of the frame or frame, and the edge of the glass plate is held by this reinforcing material. Is proposed. However, in the configuration using the reinforcing material, the material cost and the manufacturing cost of the reinforcing material itself are increased, the weight of the fitting is increased, and the work of attaching the reinforcing material is also required, which increases the product cost.

  Therefore, Patent Document 1 discloses a configuration in which the side wall on one side of the opening groove of the frame for accommodating and holding the glass plate is thickened to enhance the holding strength of the glass plate in case of fire without using a reinforcing material. Proposed.

  The heat-expandable member 34 provided in the opening groove 42 of the vertical frame 24d is also stored in the storage pocket 46 provided on the inner surface of the bottom wall portion 42a toward the outdoor side, so that the multilayer structure as shown in FIG. It is arranged so as to straddle a corner 37d on the outdoor side of the vertical side of a glass plate 26a which is a fireproof glass constituting the glass 26.

  When the shoji 16 constructed in this manner is mounted on the shoji disposing portion 18 of the frame body 14, the upper frame 14a and the upper frame 24a and the lower frame 14b and the lower frame 24b are connected by the arms 48, respectively. To be done. As a result, the shoji 16 is disposed inside the frame body 14 in a state of being openable and closable under the supporting action of the arm 48, and the lock device 49 is disposed between the one vertical frame 14d and the vertical frame 24d. .

  In the fitting 10 configured as described above, a reinforcing member made of steel or stainless steel that holds the edge portion of the double-glazing unit 26 is provided in the opening grooves 28 and 42 that accommodate and support the double-glazing unit 26 of the frame 24. Not not. Therefore, when the fitting 10 receives heat such as a fire, the frame 24 made of aluminum may be softened or melted depending on the temperature or heating time, and the double glazing 26 may not be held. There is a nature.

  Therefore, in the fitting 10, the heat-expandable members 34 in the opening grooves 28, 42 of the frames 24a to 24d are arranged so as to straddle the corners 37a to 37d of the sides of the glass plate 26a that is the fireproof glass. ing. Therefore, when the fitting 10 receives heat such as a fire, the heat-expandable member 34 arranged in each opening groove 28, 42 expands to wrap the corners 37a to 37d of each side of the glass plate 26a. Expands to. As a result, the four sides of the glass plate 26a can be stably held by the expanded heat-expandable member 34, the glass plate 26a can be prevented from falling, and the opening grooves 28, 42 can be used for indoor and outdoor heat. It is also possible to prevent the formation of a flame through hole. Therefore, unlike the prior art, it is not necessary to dispose a reinforcing material for holding the double-glazing unit 26 in the opening grooves 28 and 42, and naturally, there is no labor for disposing the reinforcing material. It is possible to secure high fire protection performance while suppressing the increase in

  At this time, as shown in FIG. 4A, the heat-expandable member 34 in the opening groove 28 of each of the frames 24a and 24b, which is a horizontal member, is disposed inside the opening groove 42 of each of the frames 24c and 24d, which is a vertical member. The heat-expandable member 34 extends to the back surface side so as to pass through the end surface of the heat-expandable member 34, and both are arranged three-dimensionally. As a result, at the time of a fire, the thermally expansive member 34 expands so as to be continuous around the glass plate 26a, so that a more stable holding effect for the glass plate 26a and a closing effect for the surrounding area can be obtained.

  Each of the frames 24a to 24d has projecting pieces 30 and 44 projecting in a direction facing the respective frames 14a to 14d on an outer prospective surface opposite to the inner prospective surface on which the opening grooves 28 and 42 are formed, A thermal expansive member 38 is arranged on each of the projecting pieces 30 and 44 so as to face the gap between the frame body 14 and the frame body 24. As a result, when the fitting 10 receives heat such as a fire, the heat-expandable member 38 arranged on each of the projecting pieces 30, 44 expands toward the gap between the frame body 14 and the frame body 24. As a result, the gap between the frame body 14 and the frame body 24 can be closed, and this gap can be prevented from becoming a through hole for heat and flame inside and outside the room.

  In the case of the present embodiment, unlike the glass plate 26a formed of fireproof glass, the glass plate 26b on the indoor side is formed of thin glass, and thus breaks and collapses when a fire occurs inside the glass plate. No holding structure such as 26a is provided. However, when the glass plate 26b on the indoor side is made of fireproof glass instead of the glass plate 26a on the outdoor side, the opening groove 28 is formed so as to straddle the corners on the indoor side or the outdoor side of the four sides of the glass plate 26b. , 42, the thermally expandable member 34 may be arranged. Further, when the two glass plates 26a and 26b are made of fireproof glass, the thermally expansive member 34 may be arranged so as to extend over one or both corners.

  In the fitting 10, the glass plate 26a, which is a fireproof glass, is arranged on the outermost side out of the glass plates 26a and 26b constituting the double glazing 26, and the thermal expansion is arranged in the respective opening grooves 28 and 42. The elastic member 34 is arranged so as to straddle the corners 37a to 37d between the outdoor-side finding surface and the prospective surface of the glass plate 26a. For this reason, compared to the case where a fire occurs inside the fitting 10, the flame / heat shielding effect due to the skeleton 12 and the like cannot be expected, and a fire occurs outside the fitting 10 that is closer to the origin of the fire and is likely to become hot. Even in the case of occurrence of, the outermost glass plate 26a can be made of fireproof glass and the periphery thereof can be held by the expanded heat-expandable member 34, so that higher fireproof performance can be secured. In particular, the fitting 10 according to the present embodiment has a mounting structure in which the frame body 14 and the frame body 24 project outside the outer wall surface of the skeleton 12 of the building, as shown in FIGS. 2 and 3. It is desirable to enhance the fire protection performance in the outdoor area.

  At this time, in the frame 24, the plate thickness t1 of the portion of the vertical frames 24c, 24d that forms the outdoor-side finding surface is thicker than the plate thickness t2 of the portion that forms the indoor-side finding surface. As a result, as described above, the heat resistance strength of the vertical frames 24c, 24d can be increased on the outdoor side of the fitting 10 where the temperature tends to be higher, so that the fire prevention performance is further improved.

  In the fitting 10, the heat-expandable members 34 arranged in the respective opening grooves 28 of the upper frame 24a and the lower frame 24b, which are upper and lower horizontal members, are mutually centered on the parallel lines along the longitudinal direction of the respective frames 24a, 24b. Each of the heat-expandable members 34, which are respectively arranged in line-symmetrical positions and arranged in the respective opening grooves 42 of the vertical frames 24c, 24d, which are the left and right vertical members, are parallel lines along the longitudinal direction of the frames 24c, 24d. Are arranged in line symmetry with respect to. As a result, the thermal expansion members 34 are arranged so as to straddle the upper and lower horizontal sides and the left and right vertical sides of the glass plate 26a, which is a fireproof glass, respectively, so that the holding balance of the glass plate 26a is improved and the glass plate 26a is improved. It is possible to hold the plate 26a more stably.

  In the fitting 10, the upper frame 24a and the lower frame 24b, which are horizontal members, are joined to the vertical frames 24c and 24d, which are vertical members, in the form of a seal, and are connected to the opening grooves 28 of the upper frame 24a and the lower frame 24b. The respective heat-expandable members 34 arranged are respectively arranged on the found surfaces of the respective opening grooves 28, and the respective heat-expandable members 34 arranged in the respective opening grooves 42 of the vertical frames 24c, 24d are arranged in the respective opening grooves 42. They are arranged on the prospective surface. As a result, as shown in FIG. 4 (A), the thermally expandable members 34 of the vertical frames 24c and 24d, which are vertical members, and the storage pockets 46 thereof are upper frames 24a, which are horizontal members to be inserted and joined in a seal-box form. Interference with the found surface of the lower frame 24b is avoided, and cutting work in the subsequent process of the storage pocket 46 and the heat-expandable member 34 housed and held therein becomes unnecessary. Further, even when the drainage hole 41 is formed on the bottom surface of the opening groove 28 of the lower frame 24b, the heat-expandable member 34 in the opening groove 28 of the lower frame 24b is arranged upright along its found surface. Therefore, it is possible to prevent the heat-expandable member 34 from interfering with the drainage path to the drain hole 41 or preventing water from permeating into the heat-expandable member 34 itself. The thermal expansion members 34 of the upper frame 24a and the lower frame 24b are arranged on the prospective surface of each opening groove 28, and the thermal expansion members 34 of the vertical frames 24c, 24d are arranged on the found surface of each opening groove 42.
