Description

  The present invention relates to a joinery having a frame member attached to a housing forming an opening at an indoor / outdoor boundary.

  Conventionally, a joinery having a frame member that is attached to a housing that forms an opening at the boundary between indoor and outdoor, the frame material fixed to the housing is easily melted, for example, if it is made of synthetic resin, by a fire etc. There is a risk of melting and falling off when heated. For this reason, for example, a fireproof resin sash is known in which a hollow member provided in a frame member is provided with a reinforcing member made of flame retardant or metal and a member for connecting the casing and the reinforcing member is provided (for example, a patent Reference 1). In such a sash, when fixing the frame member to the casing, L-shaped cross-section members joined to the casing and the reinforcing member with screws are used, and the L-shaped cross-section member is used as the casing of the frame member. It goes to the outside of the part to be fixed (the side opposite to the casing) and is fixed to the casing with a screw that penetrates them. For this reason, both the L-shaped cross-section member and the reinforcing member are fixed on the outer side (the side opposite to the casing) of the portion fixed to the casing.

  On the upper surface of the outer peripheral facing portion 11k, there is provided a fixing portion 11l extending upward from substantially the center in the prospective direction of the outdoor side hollow portion 11f and screwing the upper frame 11 to the housing 2 in a fin shape. Yes. The fixed part 11l is formed to be thinner than the upper end part 11m with the indoor side being depressed except for the upper end part 11m. A portion recessed in the fixing portion 11l constitutes a housing side accommodation portion 11n in which a later-described housing joint portion 31 of the connection fitting 30 is accommodated. In addition, a countersunk screw 40 is inserted into the fixing portion 11l from the outdoor side, and as shown in FIG. 4, an insertion hole 11p having a countersunk 11r on the outdoor side surface is appropriately spaced in the longitudinal direction of the upper frame 11. Is provided.

  In the outer peripheral facing portion 11k forming the outdoor side hollow portion 11f, a portion on the indoor side with respect to the fixed portion 11l is located below a portion on the outdoor side with respect to the fixed portion 11l. At this time, since the part on the outdoor side from the fixed part 11l forms the same horizontal plane as the tip surface part 11i of the indoor hollow part 11e, the part on the indoor side from the fixed part 11l of the outer peripheral facing part 11k is opposite to the housing 2. It is formed inside the outdoor side hollow portion 11f that is the side, that is, recessed downward, and an outer peripheral portion of the frame member 10 forms an outer peripheral recess 11o that is recessed toward the inner peripheral side. A through-hole (not shown) through which a bind screw 41 for joining the connecting metal fitting 30 and the reinforcing member 15 is formed at a portion forming the lower surface of the outer circumferential recess 11o in the outer circumferential facing portion 11k with an appropriate interval in the longitudinal direction. Is provided.

  The reinforcing member 15 includes a lower facing plate portion 15a and an upper facing plate portion 15b that face the inner circumferential surface portion 11b and the outer circumferential facing portion 11k, respectively, and the indoor side ends of the lower facing plate portion 15a and the upper facing plate portion 15b are connected to each other. It has a U-shaped cross section. The lower facing plate portion 15a and the upper facing plate portion 15b are formed between the inner peripheral surface portion 11b and the outer peripheral facing portion 11k that form the outdoor side hollow portion 11f when the reinforcing member 15 is inserted into the outdoor side hollow portion 11f. It is provided so as to be close to or in contact with the upper surface of the inner peripheral surface portion 11b and the lower surface of the outer peripheral recess portion 11o. The upper opposing plate portion 15b of the reinforcing member 15 is provided with screw holes (not shown) into which the bind screws 41 for joining to the connecting metal fitting 30 are screwed at an appropriate interval in the longitudinal direction.

On the reinforcing member 15 provided on each cross member 11, 12 and each vertical member 13, a metal holding metal 38 for holding the multi-layer glass 3 is screwed via the inner peripheral surface portions 11b, 12b, 13b. Has been. Further, on the inner peripheral surface portions 11b, 12b, and 13b of the cross members 11 and 12 and the vertical members 13, a sheet-like expansive graphite 51 is provided in the entire longitudinal direction in a state where the holding metal fitting 38 is attached. It has been.
As shown in FIG. 5, the connection fitting 30 is a stainless steel member having a L-shaped cross section, and one of the two plate portions facing the two directions of the L shape is joined to the housing 2. 31, and the other is a reinforcing member joint portion 32 to be joined to the reinforcing member 15. A slotted screw 40 that is screwed into the housing 2 passes through the housing joint 31, and a long hole that is formed so as to be longer in the longitudinal direction of the upper frame 11 when the connecting metal fitting 30 is disposed on the upper frame 11. 31a is provided, and the reinforcing member joint portion 32 is provided with a round hole 32a through which a screw to be screwed into the reinforcing member 15 passes. The connection fitting 30 of the present embodiment is formed by bending a stainless steel plate material, and the plate thickness is thinner than the amount of depression of the housing side housing portion 11n provided in the fixing portion 11l of the upper frame 11. It is formed with a member.

  When the connecting member 30 inserts the reinforcing member joint 32 into the outer peripheral recess 11o and the bind screw 41 penetrating the round hole 32a of the reinforcing member joint 32 and the through hole of the outer peripheral recess 11o is screwed into the reinforcing member 15. Further, the long hole 31a of the housing joint portion 31 and the insertion hole 11p of the fixing portion 11l are configured to coincide with each other.

  The joinery 1 according to the present embodiment is configured such that the reinforcing members 15 are inserted into the upper and lower horizontal members 11 and 12 and the left and right vertical members 13 to form a rectangular frame, and the multilayer glass 3 is fixed to the reinforcing member 15. It is attached to the housing 2 in a state where it is held by the metal fitting 38 and the pressing edge 5 is attached. At this time, in the upper frame 11, the housing joint portion 31 of the connecting metal fitting 30 is housed in the housing-side housing portion 11 n of the fixing portion 11 l, and the reinforcing member joint portion 32 is housed in the outer peripheral recess 11 o and attached to the bind screw 41. The reinforcing member 15 is joined. In this state, the head 41a of the bind screw 41 is accommodated in the outer peripheral recess 11o and does not protrude above the tip surface portion 11i. That is, the outer peripheral recess 11 o corresponds to a reinforcing member side accommodating portion that accommodates the head 41 a of the bind screw 41 that joins the reinforcing member joining portion 32 and the reinforcing member 15.

  And the joinery 1 in which the housing joint portion 31 of the connecting metal fitting 30 is housed in the housing-side housing portion 11n of the fixing portion 11l includes the upper and lower cross members 11, 12 and the left and right vertical members 13 fixing portions 11l, 12l, 13l. It is brought into contact with the housing 2 from the outdoor side and attached to the housing 2 with a flat head screw 40. Further, the interior material cover portions 11d, 12d, and 13d of the frame member 10 are also fixed through the interior material 4 such as a floor material or a frame with a countersunk screw 40 entering from the inner peripheral side to the outer peripheral side of the opening 2a. Has been.

  That is, in the frame member 10, the entering direction of the countersunk screw 40 that fixes the fixing portions 11l, 12l, and 13l and the entering direction of the countersunk screw 40 that fixes the interior material cover portions 11d, 12d, and 13d are substantially orthogonal. Therefore, it is fixed more firmly than the case where it is fixed only by the screw entering in one direction.

  In a state in which the joinery 1 is fixed to the housing 2, the connection fitting 30 is disposed indoors from the fixing portions 11 l, 12 l, and 13 l of the upper and lower cross members 11 and 12 and the left and right vertical members 13. Further, since the housing joint portion 31 of the connecting metal fitting 30 is attached to the housing 2 in a state of being housed in the housing-side housing portion 11n, the upper end portion 11m of the fixing portion 11l contacts the housing 2 in the entire longitudinal direction. Is done.

  After the joinery 1 is attached to the housing 2, a double-sided waterproof tape 33 is applied across the housing 2 and the fixing portions 11 l, 12 l, 13 l and over the entire area in the longitudinal direction. An edge 35, a siding material 36, a parting edge 37, and the like are provided, and a backup material 45 and a sealing 46 are provided to form an outer wall.

  According to the joinery 1 of the present embodiment, the connection fitting 30 that connects the reinforcing member 15 and the housing 2 provided in the outdoor-side hollow portion 11f of the upper frame 11 is disposed indoors from the fixing portion 11l. The bind screw 41 that fixes the reinforcing member 15 and the reinforcing member joint portion 32 of the connection fitting 30 is disposed on the indoor side from the fixing portion 11l. That is, when the housing joint portion 31 of the connection fitting 30 is housed in the housing-side housing portion 11n of the fixing portion 11l and screwed to the housing 2, the reinforcing member joint portion 32 is disposed further indoors than the housing joint portion 31. Is done. At this time, since the thickness of the housing joint portion 31 is thinner than the hollow amount of the housing-side housing portion 11n, the housing joint portion 31 does not discharge from the fixed portion 11l to the housing 2 side, and thus the upper end portion 11m of the fixed portion 11l becomes the housing 2 It abuts over almost the entire area in the longitudinal direction. For this reason, it is difficult for a gap to be formed between the housing 2 and the upper end portion 11m of the fixed portion 11l. Therefore, the reinforcing member 15 and the reinforcing member joint portion 32 positioned on the indoor side from the fixed portion 11l are joined. It is possible to prevent water leakage from the threaded portion of the bind screw 41 to the indoor side. Therefore, it is possible to provide the joinery 1 in which water leakage from the threaded portion of the bind screw 41 serving as a connecting portion that connects the reinforcing member 15 provided on the synthetic resin frame member 10 and the housing 2 hardly occurs. .

  Further, the upper frame 11 is formed with an outer peripheral recess 11o that is recessed toward the center side of the opening 2a formed by the housing 2, that is, the lower side, and the outer peripheral recess 11o is fixed to the housing 2 by the fixing portion 11l. It is arranged on the indoor side from the part that is. For this reason, for example, even if dew condensation occurs in the ventilation layer provided inside the siding material 36 and the condensed water leaks into the indoor side from between the fixed portion 11l and the housing 2, the upper frame 11 has a lower side. It is possible to retain water at the outer peripheral recess 11o that is recessed. For this reason, it is possible to provide the fitting 1 which is hard to leak on the indoor side.

  Further, since the housing joint portion 31 is housed in the housing-side housing portion 11n provided in the fixing portions 11l, 12l, and 13l, it is fixed even if the width of the connecting metal fitting 30 is narrower than the width of the housing-side housing portion 11n. There are no gaps between the portions 11l, 12l, 13l and the housing 2. For this reason, by reducing the width of the connecting fitting 30, it is possible to reduce the weight of the joinery 1 and reduce the cost.

  Further, since the housing joint portion 31 of the connection fitting 30 is housed in the housing-side housing portion 11n of the fixing portion 11l and the housing joint portion 31 does not discharge from the fixing portion 11l to the housing 2 side, the width of the connection fitting 30 is accommodated in the housing-side housing. Even if it is narrower than the width of the portion 11n, it is possible to keep the fixing portion 11l of the upper frame 11 along the surface of the housing 2 in a flat state. For this reason, when the double-sided waterproof tape 33 is affixed over the entire region in the longitudinal direction and straddling the housing 2 and the fixing portion 11l, the double-sided waterproof tape 33 is unlikely to float. For this reason, since it is possible to affix the double-sided waterproof tape 33 to the housing 2 without a gap, it is possible to attach the joinery 1 in a more waterproof state.

  Further, since there is only a plate-shaped portion of the outer peripheral facing portion 11k of the frame member 10 between the reinforcing member joint portion 32 and the reinforcing member 15, the reinforcing member joint portion 32 and the reinforcing member 15 are more connected. It is possible to firmly bond the frame material 10 to the housing 2 more securely.

  In the said embodiment, although the site | part of the outer periphery facing part 11k was provided with the outer periphery recessed part 11o located in the indoor side part from the fixing | fixed part 11l below the part of the outdoor side from the fixing | fixed part 11l, this was demonstrated. It is not limited to. For example, as shown in FIG. 6, a step portion that is flush with the tip surface portion 11 i is provided on the indoor side of the fixing portion 11 l, and the outer peripheral recess 11 o as a reinforcing member side housing portion is provided between the step portion 11 s and the tip surface portion 11 i. May be provided. In this case, the shape of the connecting metal fitting 30 is a shape that is connected to the step portion 11s and the outer peripheral recess 11o from the lower end of the housing joint portion 31 facing the housing 2 in the housing-side housing portion 11n of the fixing portion 11l.

  Moreover, although the example which hollowed the outer periphery recessed part 11o as a reinforcement member side accommodating part toward the center side of the opening 2a was demonstrated, as shown in FIG. 7, the hollow part 11t in which the reinforcement member 15 is accommodated is a fixed part. In the case of the joinery 1 that is located more on the outdoor side, the reinforcing member side accommodating portion 11o may be formed to be recessed on the outdoor side.

  In the said embodiment, although demonstrated taking the example of the fixture 1 for FIX windows by which the multilayer glass 3 was attached to the frame member so that opening and closing was not possible, it is not restricted to this, and the fixture and the finding provided with the door which can be opened and closed It may be a fitting with a shoji that can move in the direction.

  In the said embodiment, although the example which was set as the laminated glass 3 which formed two sheet glass facing each other with the space | interval spaced apart from each other was demonstrated, the face material is one glass plate, Alternatively, it may be a multi-layer glass in which three or more sheet glasses face each other at an interval and are integrally formed. Further, the face material is not limited to glass, and may be a plate-like interior material or exterior material. Further, the frame material may not be provided with a face material, for example, a frame material constituting a panel material.

  Moreover, in the said embodiment, although the screw which fixes the frame material 10 to the housing 2 was set as the flat head screw 40, and the screw which joins the connection metal fitting 30 and the reinforcement member 15 was set as the bind screw 41, it does not restrict to this. .

  In the above embodiment, the frame member 10 is made of synthetic resin, and the reinforcing member and the connecting member are made of iron. However, the present invention is not limited to this. For example, the frame member has a small thickness for weight reduction and cost reduction. The frame material made of aluminum or the like is a frame material that is easier to melt than the non-combustible material and the flame retardant material forming the reinforcing member and the connecting member when heated, and the reinforcing member and the connecting member are heated and melted from the frame material. Any member can be used as long as it is difficult to do.

  The reinforcing member is not limited to a non-combustible reinforcing member, and the surface is first carbonized by a fire, and can be retarded from burning inside due to the heat insulating effect of the carbonized surface, for example, MDF, wood, etc. Any flame retardant reinforcing member may be used.

  In addition, although the connecting metal fitting (connecting member) 30 is made of non-combustible iron, it may be composed of a non-combustible metal such as stainless steel or a non-combustible member that takes time to burn. Absent.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
