Description

  The present invention relates to a method for fixing a sash frame of a window or a door in a substantially rectangular opening provided in a housing such as a concrete wall surface of a building.

  In general, when a window is attached to a substantially rectangular opening provided on a building wall or the like, a window frame formed in a rectangular frame shape is first fixed to the opening, and then the window body is assembled to the window frame. It has become.

  By the way, for example, when renovating a building, it is also possible to replace existing windows with new windows and refurbish them, but as a construction method in such cases, leave the existing window frame as it is, A general method is to fix a new window frame to the remaining existing window frame by welding or the like and attach a new window body to the new window frame (see, for example, Patent Document 1).

  However, according to the method of fixing the new window frame to the existing window frame in this way, the new window frame must be smaller than the existing window frame because of its structure. A gap is inevitably generated between the portion and the new window frame. As a method for eliminating this gap, in Patent Document 1, an external attachment is disposed on the outer peripheral surface of the outdoor side of the new window frame, thereby closing the gap and ensuring airtightness.

  However, since this external attachment has a rigid structure made of iron plate and it is difficult to finely adjust the shape and dimensions afterwards, for example, distortion or bending deformation has occurred in the existing window frame or the surrounding casing. In such a case, it is necessary to produce a new window frame in accordance with this distortion or bending deformation, which causes problems in terms of workability and cost.

  From such a background, in Patent Document 2, the existing window frame and the new window frame are fixed by a jig such as a flat bar or an angle, and in this fixed state, foamed urethane is formed in a gap portion between the existing window frame and the new window frame. A method of filling the material has been proposed.

  In this way, according to the method of filling the gap between the existing window frame and the new window frame with urethane foam, even if distortion or bending deformation of the existing window frame or the surrounding frame occurs, it will be affected by this. Therefore, the gap can be surely closed to ensure the airtightness, which is advantageous in terms of workability and cost, for example, as compared with the conventional method as disclosed in Patent Document 1. On the other hand, urethane foam has a problem of heat melting. For example, in the event of a fire in a building, urethane foam may be melted by receiving fire heat, but the existing window frame and the new window frame are flattened as described above. Since it is fixed with a jig such as a bar or an angle, even if the urethane foam is melted, the connection between the new window frame and the existing window frame is maintained, and the new window frame is detached from the existing window frame. Falling is reliably avoided, ensuring safety in the event of a fire.

  In other words, due to the synergistic effect of fixing the new window frame to the existing window frame with a jig and filling the gap between the existing window frame and the new window frame with urethane foam, Both ensuring the functions of the system and ensuring safety in the event of a fire are compatible.

  However, for example, when a window frame is attached to a new building, the existing window frame does not exist at the opening on the building side as when renovating the window, so the new window frame is fixed to the existing window frame. I can't do it. For this reason, in such a case, for example, the window frame is temporarily placed and supported in a state where a predetermined gap is secured between the opening and the inner periphery thereof, and then the gap between the opening and the window frame is supported. A method of filling foamed urethane, fixing the window frame to the opening side with the foamed urethane, and ensuring airtightness between the opening and the window frame is adopted.

  However, according to the construction method in which the foamed urethane is directly filled in the gap between the inner periphery of the opening and the window frame in this way, the airtightness of the window frame portion is ensured by the foamed urethane during normal times and the opening of the window frame There is no problem because the fixed holding state to the side is maintained, but for example, in the case of a fire in a building, the foamed urethane melts due to high-temperature fire heat, and the function of holding the window frame by the foamed urethane Disappears and the window frame is likely to fall out of the opening and fall, and there is a problem in securing safety in the event of a fire or the like.

  Accordingly, the present invention proposes a method for fixing a sash frame that can reliably prevent the sash frame from being detached and dropped with a simple and inexpensive configuration when the sash frame is fixed to the opening of the housing using a foamable resin.

  In the present invention, the following configuration is adopted as a specific means for solving such a problem.

In the first invention of the present application, a sash frame having a window or door sash frame provided with grooves extending in the sash height direction on both right and left sides is fixed in a substantially rectangular opening provided in the housing. In this case, a heat-resistant locking member that protrudes inward of the opening is provided at a position near at least the left and right side wall surfaces of the opening, and at least one of the locking members protrudes inward of the opening. Bending deformation so as to reduce the amount to avoid interference with the sash frame, the sash frame is fitted into the opening, and the groove portions of the sash frame are respectively formed on the left and right side wall surfaces of the opening. After facing each other, the locking members bent and deformed are bent and deformed so as to increase the amount of protrusion inward of the opening , whereby the locking members enter the grooves of the sash frame, respectively. And then above Mouth portion and the sash frame by causing foaming and curing to fill the foamable resin to substantially the entire area of the space between the sash frame is characterized in that secured within the opening.

  Here, the sash frame is a concept including not only a window frame but also a frame of other fitting such as a door frame. Further, the frame is a concept including not only general concrete walls and columns but also walls and columns made of lightweight cellular concrete (ALC), metal, and other composite materials.

  Here, the locking member has a size such that the amount of protrusion inward of the opening when the opening is attached to the side wall surface interferes with the sash frame when the sash frame is fitted into the opening. It is premised that it is set, and if necessary, this is bent and deformed to increase or decrease the amount of protrusion into the opening.

In the second invention of the present application, a sash frame having a window or door sash frame provided with grooves extending in the sash height direction on both right and left sides thereof is fixed in a substantially rectangular opening provided in the housing. At the time, at the upper side position of at least the left and right side wall surfaces of the opening, respectively provided with a heat-resistant locking member that can be deployed from the side wall surface to the inside of the opening with the side wall surface side as a pivot point, Each of the locking members is housed near the side wall surface of the opening and is held in a state where the amount of protrusion toward the inside of the opening is reduced, and then the sash frame is fitted into the opening and the sash is fitted. After the respective groove portions of the frame are opposed to the left and right side wall surfaces of the opening, the locking members are expanded to the inner side of the opening to increase the amount of the protrusions. Enter into each groove of the sash frame, Ide, and the sash frame by causing foaming and curing to fill the foamable resin to substantially the entire area of the space between the opening and the sash frame is characterized in that secured within the opening.

In the third invention of the present application, a sash frame having a window or door sash frame provided with grooves extending in the sash height direction on both right and left sides thereof is fixed in a substantially rectangular opening provided in the housing. In this case, a heat-resistant locking member protruding inward of the opening is provided at a position near the upper portion of one of the left and right sidewall surfaces of the opening, and the upper portion of the other sidewall surface. A heat-resistant locking member that can be deployed from the side wall surface to the inner side of the opening is provided at the side position, and the sash frame is fitted into the opening. After the respective groove portions of the sash frame are opposed to the left and right side wall surfaces of the opening portion, the locking member provided on the one side wall surface is bent and deformed to protrude into the opening portion. Of the sash frame without increasing or bending deformation The locking member provided on the other side wall surface of the sash frame is expanded into the opening portion inward to increase the amount of protrusion into the opening portion, and the groove portion of the sash frame. The sash frame is fixed in the opening by filling the foamed resin into the substantially entire space of the space between the opening and the sash frame and curing the foam. It is said.

In the fourth invention of the present application, a sash frame having a window or door sash frame provided with grooves extending in the sash height direction on both right and left sides is fixed in a substantially rectangular opening provided in the housing. At this time, a heat-resistant locking member protruding inward of the opening is provided at a position closer to the upper part of at least the left and right side wall surfaces of the opening. In this state, the sash frame is centered on the center line in the width direction. After being fitted into the opening in a torsionally deformed state, the locking members are inserted into the grooves of the sash frame, respectively, and then the sash frame is returned to a substantially original shape, and then the opening is opened. The sash frame is fixed in the opening by filling a foamable resin over substantially the entire space of the space between the sash frame and the sash frame and curing the foamed resin.

  Here, when the locking member is attached to the side wall of the opening, the amount of protrusion of the locking member to the inside of the opening is such that the locking member fits the sash frame in a state where the sash frame is fitted in the opening. The size is set so as to be able to enter the groove and is held as it is, and the amount of protrusion is not changed afterwards.

  In the present invention, the following effects can be obtained.

(A) 1st invention of this application According to the fixing method of the sash frame which concerns on 1st invention of this application, in the fitting state to the said opening part of the said sash frame, at least the left-right side wall surface of the said opening part When the heat-resistant locking member provided near the upper part of the sash enters the groove provided on the left and right side surfaces of the sash frame, and the sash frame moves in the thickness direction (inside and outside of the window) The engaging member engages with the side wall portions located on both sides in the width direction of the groove portion, and further movement of the sash frame is restricted.

  Therefore, in a state where the space between the sash frame and the opening is filled with a foamable resin, and this is foam-cured and the sash frame is fixedly held on the opening by the foamable resin, for example, a building When the foaming resin melts and the fixing and holding function for the sash frame disappears due to the fire, the sash frame falls by its own weight as the foaming resin melts, and on the lower inner surface of the opening. Further contact with the sash frame is prevented by the contact, and at a position near the upper portion of the sash frame, the movement restricting action by the engagement between the locking member and the side wall of the groove portion causes the sash frame to move in the thickness direction. The movement (tilting) is restricted, and as a synergistic effect thereof, the sash frame is reliably prevented from being detached and dropped from the opening, and safety in a fire is ensured.

In the sash frame fixing method according to the present invention, at least one of the locking members is bent and deformed so as to reduce the amount of protrusion inward of the opening when the sash frame is fitted into the opening. While avoiding interference with the frame, after the sash frame is fitted into the opening, it is bent and deformed to increase the amount of inward protrusion of the opening (that is, after the fact) Therefore, when the sash frame is attached to the opening side, the locking member protrudes inwardly when the sash frame is fitted and after the fitting. Without worrying much about the amount, the mounting direction of the locking member can be arbitrarily set mainly focusing on the ease of mounting of the locking member. Simplification and improved workability It is.

( B ) Second invention of the present application According to the sash frame fixing method according to the second invention of the present application, when the sash frame is fitted into the opening, at least the left and right side wall surfaces of the opening. A heat-resistant locking member provided near the top of the sash is expanded so as to increase the amount of protrusion inward of the opening and enters each groove of the sash frame, and the sash frame has a thickness thereof. When moving in the direction (inside and outside of the window), the locking member engages with the side wall portions located on both sides in the width direction of the groove portion, and further movement of the sash frame is restricted. ing.

  Therefore, in a state where the space between the sash frame and the opening is filled with a foamable resin, and this is foam-cured and the sash frame is fixedly held on the opening by the foamable resin, for example, a building When the foaming resin melts and the fixing and holding function for the sash frame disappears due to the fire, the sash frame falls by its own weight as the foaming resin melts, and on the lower inner surface of the opening. Further contact with the sash frame is prevented by the contact, and at a position near the upper portion of the sash frame, the movement restricting action by the engagement between the locking member and the side wall of the groove portion causes the sash frame to move in the thickness direction. The movement (tilting) is regulated, and as a synergistic effect of these, the sash frame is reliably prevented from being detached and dropped from the opening, and as a result, safety in a fire is ensured. .

  Further, the locking member can be developed from the side wall surface to the inner side of the opening with the side wall surface side of the opening as a pivot point, and the adjustment of the amount of protrusion to the inner side of the opening is accommodated on the side wall surface side. Since the adjustment is performed by the operation and the inward opening operation, for example, the adjustment operation of the protrusion amount is small compared to the case where the adjustment of the protrusion amount to the inside of the opening is performed by bending deformation of the locking member. It can be performed quickly with the operating force, and the workability in fixing the sash frame is improved accordingly.

( C ) Third invention of the present application According to the fixing method of the sash frame according to the third invention of the present application, in the fitted state of the sash frame in the opening, on one side wall surface of the opening. The provided locking member enters a groove portion provided on one side surface of the sash frame, and when the sash frame moves in the thickness direction, the locking member is moved in the width direction of the groove portion. The side wall portions located on both sides of the sash frame are engaged to restrict further movement of the sash frame. Further, the locking member provided on the other side wall surface of the opening is deployed so as to increase the amount of protrusion inward of the opening and enters the groove of the sash frame, and the sash frame Is moved in the thickness direction, the locking member engages with the side wall portions located on both sides in the width direction of the groove portion, thereby restricting further movement of the sash frame.

  Therefore, in a state where the space between the sash frame and the opening is filled with a foamable resin, and this is foam-cured and the sash frame is fixedly held on the opening by the foamable resin, for example, a building When the foaming resin melts and the fixing and holding function for the sash frame disappears due to the fire, the sash frame falls by its own weight as the foaming resin melts, and on the lower inner surface of the opening. Further contact with the sash frame is prevented by the contact, and at a position near the upper part of the sash frame, the movement restricting action by the engagement between the locking members and the side wall of the groove portion causes the sash frame to move in the thickness direction. As a synergistic effect, the sash frame is reliably prevented from being detached and dropped from the opening, and as a result, safety in a fire is ensured. That.

( D ) 4th invention of this application According to the fixing method of the sash frame which concerns on the 4th invention of this application, in the fitting state in the said opening part of the said sash frame, at least the left-right side wall surface of the said opening part When the heat-resistant locking member provided near the upper part of the sash enters the groove provided on the left and right side surfaces of the sash frame, and the sash frame moves in the thickness direction (inside and outside of the window) The engaging member engages with the side wall portions located on both sides in the width direction of the groove portion, and further movement of the sash frame is restricted.

  Therefore, in a state where the space between the sash frame and the opening is filled with a foamable resin, and this is foam-cured and the sash frame is fixedly held on the opening by the foamable resin, for example, a building When the foamable resin is melted by the fire and the fixing and holding function for the sash frame disappears, the sash frame falls by its own weight as the foamable resin melts, and on the lower inner surface of the opening. Is prevented from further descending, and in the position closer to the upper portion of the sash frame, in the thickness direction of the sash frame due to the movement restricting action due to the engagement between the locking member and the side wall of the groove. As a synergistic effect, the sash frame is reliably prevented from being detached and dropped from the opening, and as a result, safety in a fire is ensured. That.

  Further, according to the present invention, the sash frame is fitted in the opening in a state where the sash frame is torsionally deformed with the center line in the width direction as an axis, and the locking members are respectively inserted into the grooves of the sash frame. Since the structure is such that the sash frame is restored to its original shape after the sash frame has been moved, the locking member is configured so that the amount of protrusion inward of the opening is determined in the state where the sash frame is fitted in the opening. It is only necessary to set the stop member from the beginning so that the stop member can enter the groove portion of the sash frame, and it is not necessary to change this afterwards. Therefore, for example, the workability in fixing the sash frame is improved as compared with a case where it is necessary to adjust the amount of protrusion of the locking member into the opening portion afterwards.

A: First embodiment Aa: Sash frame 1
FIG. 1 shows a sash frame 1 for a window that is a target for carrying out the fixing method according to the present invention. The sash frame 1 is configured by assembling a shape member having a predetermined cross-sectional shape into a rectangular frame shape, and includes an upper frame portion 1a, a lower frame portion 1b, and left and right side frame portions 1c. The inner part is a mounting space 1d for a window body (not shown).

  Further, the sash frame 1 is provided with groove portions 2 extending in the height direction of the sash frame 1 on both side surfaces thereof, that is, on the outer surface of the side frame portion 1c. The groove portion 2 is composed of a pair of side wall portions 2b opposed to each other at a predetermined interval in the thickness direction of the side frame portion 1c and a bottom surface portion 2a positioned therebetween.

  In addition, in this embodiment, although what provided the said groove part 2 only in the outer surface of each said side frame part 1c is illustrated, this invention is not limited to this. That is, the sash frame fixing method according to the present invention realizes prevention of falling of the sash frame 1 by using the groove portions 2 provided on the outer surfaces of the left and right side frame portions 1c of the sash frame 1. It is sufficient that the groove 2 is provided on at least the outer surface of each side frame 1c. For example, in addition to each side frame 1c, the upper frame 1a and the lower frame 1b also have the groove. Those provided with 2 are also applicable.

  And the said sash frame 1 concerns on this invention in the rectangular opening part 4 provided in the concrete wall 3 (it corresponds to the "casing body" in a claim) as shown in FIGS. It is fixed by the fixing method. Hereinafter, this fixing method will be described in detail along the work procedure.

Ab: Fixing operation of the sash frame 1 Ab-1: Attaching the locking member 10 to the opening 4 The opening 4 provided in the concrete wall 3 has the sash frame 1 on its outer peripheral surface. (See FIG. 3). And the locking member 10 which cooperates with each side wall part 2b of the said groove part 2, and exhibits the fall prevention function of the said sash frame 1 is attached to the upper position of the left and right side wall surfaces 4c of the said opening part 4. As shown in FIG. (See FIGS. 2, 5, and 6).

  In this embodiment, a nail body 5 that can be driven into concrete is employed as the locking member 10. The nail body 5 is driven and held at a position near the upper portion of the side wall surface 4c of the opening 4 by a predetermined length, and the head side is protruded by a predetermined amount inward of the opening 4, and the protruding portion is The amount of protrusion can be adjusted by bending and deforming.

  That is, as shown by the solid line in FIG. 5, the nail body 5 driven slightly obliquely upward is bent and deformed downward as shown by the chain line in the figure to inwardly open the opening of the nail body 5. The projection amount is set to the initial projection amount by subtracting from the initial driving amount (in the state shown by the solid line). As shown in FIGS. 3 and 5, the initial protrusion amount is obtained when the sash frame 1 is disposed in the opening 4 with a predetermined gap between the opening 4 and the side wall surface 4 c. The amount of protrusion does not interfere with the side wall 2b of the groove 2 of the frame 1.

  In this embodiment, the projecting amounts of the nail bodies 5 provided on the left and right side wall surfaces 4c of the opening 4 are both set to the initial projecting amount. However, the present invention is limited to such a configuration. In other embodiments, for example, the protruding amount of one nail body 5 is maintained as the protruding amount at the time of initial driving, and the protruding amount of only the other nail body 5 is maintained as the initial protruding amount. It is also possible to set to. However, in this case, the sash frame 1 is passed through the opening 4 between the protruding tip of one nail body 5 as originally driven and the protruding tip of the other nail body 5 set to the initial protruding amount. It is necessary to fit inside.

A-b-2: Mounting operation of sash frame 1 First, as shown in FIG. 3, the sash frame 1 is mounted in the opening 4. In this case, the right and left side wall surfaces 4c of the opening 4 are attached with the nail body 5 with the amount of protrusion inward of the opening set to the initial protrusion amount. The sash frame 1 is fitted into the opening 4 through the space between the bodies 5, and the groove portions 2 of the sash frame 1 are opposed to the left and right side wall surfaces 4c of the opening 4, respectively. Therefore, in this state, each of the nail bodies 5 faces the groove portion 2 of the sash frame 1 from the side.

  In this state, the sash frame 1 is temporarily provided with a predetermined gap between the sash frame 1 and the inner surface of the opening 4 by an appropriate spacing member (not shown) temporarily placed between the opening 4 and the inner surface. It is supported.

  Thereafter, each nail body 5 is bent and deformed to increase the amount of protrusion toward the inside of the opening. That is, as shown in FIG. 5, the nail body 5 in the state shown in the chain line (that is, the initial protruding amount) is bent upward and deformed as shown by the solid line in FIG. Enter inside. This completes the fitting operation of the sash frame 1 into the opening 4. In this state, the sash frame 1 is movable in the thickness direction only within a range in which the nail body 5 engages with the side wall portions 2b before and after the groove portion 2, and further movement is restricted. Will be.

Ab-3: Injection and filling operation of foamable resin First, a sealing material such as a cut tape is attached between the front and back surfaces of the sash frame 1 and the inner surface of the opening 4, and the outer periphery of the sash frame 1 And the space 9 between the inner periphery of the opening 4 is sealed.

  Next, a resin injection port is provided in the sealing material, and a hard foamable resin, for example, a two-component hard foamed urethane, is injected into the space portion 9 using an injection gun. However, at this time, since the sash frame 1 is temporarily supported by the spacing member, in order to remove the sash frame 1, first, a small amount of hard foamed urethane is injected into an appropriate number of locations in the space portion 9, And the sash frame 1 is temporarily supported in the opening 4 by the cured resin, the spacing member is removed, and the sealing material is corrected.

  Thereafter, hard foamed urethane is injected and filled in the entire space 9 between the opening 4 and the sash frame 1 and foamed and cured to obtain a resin cured body 8. The portion 9 is closed to ensure its airtightness, and the sash frame 1 is fixedly held on the opening 4 side (see FIGS. 4 to 6). Thus, the fixing operation of the sash frame 1 to the opening 4 is completed. After that, the window body is mounted in the sash frame 1.

Ac: Specific effects, etc. According to the fixing method of the sash frame of this embodiment, when the sash frame 1 is completely installed in the opening 4, the sash frame 1 has the opening 4. Is firmly and airtightly fixed and held on the side of the opening 4 by the adhesiveness and shape-retaining property of the hardened resin foam 8 which is filled with foamed and hardened urethane.

  In addition, when the sash frame 1 is fitted into the opening 4, the nail bodies 5 provided near the upper portions of the left and right side wall surfaces 4 c of the opening 4 are on both left and right side surfaces of the sash frame 1. Side walls that are located on both sides of the groove 2 in the width direction when the sash frame 1 moves in the thickness direction (inside and outside of the window). 2b is engaged, and further movement of the sash frame 1 is restricted.

  Therefore, the space between the sash frame 1 and the opening 4 is filled with a foamable resin and foamed and cured to form a cured resin body 8, and the sash frame 1 is opened by the resin cured body 8. In the state of being fixedly held on the part 4 side, for example, when the resin cured body 8 is melted due to a building fire and the function of fixing and holding the sash frame 1 disappears, the sash frame 1 8 is lowered by its own weight as it melts, and further lowering is prevented by coming into contact with the lower inner surface 4b of the opening 4, and at the position closer to the upper portion of the sash frame 1, the nail body 5 and Since the movement (tilting) of the sash frame 1 in the thickness direction is restricted by the movement restricting action by the engagement of the groove 2 with the side wall 2b, the sash frame 1 has the opening portion as a synergistic effect thereof. Separation from 4 and falling Is reliably prevented, as a result, safety in case of fire is ensured.

B: Second Embodiment FIGS. 7 and 8 show a main part of a sash frame fixing method according to a second embodiment of the present invention. The fixing method of this embodiment is the same as the fixing method of the first embodiment, and the difference is the configuration of the locking member 10.

  That is, in the fixing method of the first embodiment, the nail body 5 is adopted as the locking member 10, whereas in this embodiment, the locking member 10 is shown in a perspective view in FIG. In this way, a plate member 6 having a predetermined size is bent at an intermediate position to form a fixed portion 6a and a protruding portion 6b. At the time of production, the plate body 6 is bent so as to have an obtuse crossing angle with respect to the fixed portion 6a as shown by the chain line (manufactured shape).

  The plate body 6 is fixed by the fixing tool 11 in a state where the fixed portion 6a is abutted with the side wall surface 4c of the opening 4 while being in the shape as produced, and in the fixed state, The sash frame 1 is fitted into the opening 4 through the space between the left and right plate bodies 6. That is, the protruding amount of the plate body 6 in the manufactured shape (that is, the distance from the fixed portion 6a at the tip of the protruding portion 6b) is determined when the sash frame 1 is fitted into the opening 4. The dimensions are set so as not to interfere with the side wall 2b of the groove 2 provided on the left and right sides of the frame 1.

  Therefore, only by attaching the plate body 6 to the side wall surface 4c of the opening 4, there is no need to perform other prior work, and the sash frame 1 can be fitted as it is. The point is that in the nail body 5 of the first embodiment, after the nail body 5 is attached to the opening 4 side, before the fitting of the sash frame 1, the inside of the opening of the nail body 5 This is different from the one that requires the prior work of bending and deforming the protrusion so as to reduce the amount of protrusion.

  Further, the sash frame 1 is fitted into the opening 4 with the plate body 6 attached, and the groove portions 2 provided on the both side frame portions 1 c are respectively connected to the left and right sides of the opening 4. It is made to oppose each side wall surface 4c. Therefore, in this state, each plate body 6 is in a state of facing the groove portion 2 of the sash frame 1 from the side.

  Thereafter, the projecting portion 6b of each plate body 6 is bent and deformed upward as shown by a solid line in FIG. This completes the fitting operation of the sash frame 1 into the opening 4. In this state, the sash frame 1 is movable in the thickness direction only within a range where the plate body 6 engages with the front and rear side wall portions 2b of the groove portion 2, and further movement is restricted. Will be. In this case, since the plate body 6 has a larger width dimension (dimension in the thickness direction of the sash frame 1) than the nail body 5, the nail body 5 is used as in the first embodiment. Compared to the above, the movable range of the sash frame 1 is narrowed, which is advantageous in terms of preventing the sash frame 1 from falling.

  Next, in the same manner as in each of the above embodiments, hard foamed urethane is injected and filled into the space 9 between the outer periphery of the sash frame 1 and the inner periphery of the opening 4, and this is foam-cured and cured. The hardened body 8 is used to block the space 9 with the resin hardened body 8 to ensure its airtightness, and the sash frame 1 is fixedly held on the opening 4 side (see FIGS. 7 and 8). Thus, the fixing operation of the sash frame 1 to the opening 4 is completed.

  Thus, the space portion 9 is made of rigid foamed urethane 8 in a state in which the protruding portion 6b of the plate body 6 attached to the side wall surface 4c of the opening 4 is inserted into the groove portion 2 on the sash frame 1 side. By filling and foaming and curing the resin to form the resin cured body 8, for example, when the resin cured body 8 is melted due to a fire in a building and the fixing and holding function for the sash frame 1 disappears, the sash frame 1 Is lowered by its own weight with the progress of melting of the cured resin body 8, and further lowering is prevented by coming into contact with the lower inner surface 4b of the opening 4, and at a position near the upper portion of the sash frame 1. As the synergistic effect of the movement of the sash frame 1 in the thickness direction (tilt) is restricted by the movement restricting action caused by the engagement between the protrusion 6b of the plate body 6 and the side wall 2b of the groove 2. , Sash frame above Is a leaving and dropping from the opening 4 is reliably prevented, as a result, safety in case of fire is ensured.

  Since the operations and effects other than those described above are the same as those in the case of the first embodiment, the corresponding portions are cited and the description thereof is omitted here.

C: Third Embodiment FIGS. 9 to 11 show a main part of a sash frame fixing method according to a third embodiment of the present invention. The fixing method of this embodiment is the same as the fixing method of the first and second embodiments, and the difference is the configuration of the locking member 10.

  That is, the nail body 5 is employed as the locking member 10 in the fixing method of the first embodiment, and the plate body 6 is employed as the locking member 10 in the fixing method of the second embodiment. In contrast, in this embodiment, as the locking member 10, as shown in a perspective view in FIG. 9, two plate members of a predetermined size are connected by a hinge 7c, and one plate member is fixed to the fixing portion 7a. The other plate member is composed of a hinge body 7 having a developed portion 7b. The hinge body 7 is in a posture in which the fixing portion 7a stands up from the hinge 7c so that the fixing portion 7a abuts on the side wall surface 4c of the opening 4 and this is fixed to the fixture 11. It is attached to the opening 4 side by fixing with.

  In this attached state, as shown in FIG. 10, the unfolded portion 7b is a “retracted position” held in a state where the unfolded portion 7b rises upward from the hinge 7c and abuts against the front surface of the fixed portion 7a. As shown by the solid line in the figure, when the sash frame 1 is deployed forward with the hinge 7c as a center, and the sash frame 1 is fitted in the opening 4, the sash frame 1 enters the groove 2 of the sash frame 1. The posture can be changed between “deployed positions” that are in contact with the bottom surface portion 2a and are held in an inclined state.

  Accordingly, the hinge body 7 allows the sash frame 1 to be fitted into the opening 4 in the “retracted position”, while fitting in the opening 4 in the “deployed position”. A function of engaging the side wall portion 2b of the groove portion 2 on the side of the sash frame 1 mounted in the thickness direction of the side sash frame 1 and restricting the movement of the sash frame 1 in the thickness direction within a predetermined range. To do.

  The fitting operation of the sash frame 1 to the opening 4 is first performed by setting the hinge body 7 to the “retracted position” and, in that state, fitting the sash frame 1 in the opening 4. The grooves 2 are opposed to the left and right side wall surfaces 4c of the opening 4, respectively. Accordingly, in this state, each hinge body 7 faces the groove portion 2 of the sash frame 1 from the side.

  Thereafter, the unfolded portion 7b of the hinge body 7 is unfolded forward from the “retracted position” and enters the groove portion 2 side, and is brought into contact with the bottom surface portion 2a of the groove portion 2. This completes the fitting operation of the sash frame 1 into the opening 4.

  In this state, the sash frame 1 is movable in the thickness direction only within a range in which the unfolded portion 7b of the hinge body 7 is engaged with the front and rear side wall portions 2b of the groove portion 2, and more than that. Movement will be regulated. In this case, the hinge body 7 has a larger width dimension (dimension in the thickness direction of the sash frame 1) than the nail body 5 in the first embodiment. Thus, the movable range of the sash frame 1 is narrowed, which is advantageous in terms of preventing the sash frame 1 from falling.

  Further, the unfolding portion 7b of the hinge body 7 is configured to be swingable in the unfolding direction and the unfolding angle is defined by the contact of the groove portion 2 with the bottom surface portion 2a. When the sash frame 1 is positioned by shifting the sash frame 1 in the left-right direction in the mounting operation of the sash frame 1, the displacement of the window frame 1 in the left-right direction is absorbed by the swing of the unfolding portion 7b. The engagement state between the portion 7b and the side wall portion 2b of the groove portion 2 is maintained well, and the movement restricting action of the sash frame 1 is not impaired.

  Next, in the same manner as in each of the above embodiments, hard foamed urethane is injected and filled into the space 9 between the outer periphery of the sash frame 1 and the inner periphery of the opening 4, and this is foam-cured and cured. The hardened body 8 is used to block the space 9 with the resin hardened body 8 to ensure its airtightness, and the sash frame 1 is fixedly held on the opening 4 side (see FIGS. 10 and 11). Thus, the fixing operation of the sash frame 1 to the opening 4 is completed.

  In this state, the space portion 9 is made of rigid foamed urethane 8 in a state in which the developed portion 7b of the hinge body 7 attached to the side wall surface 4c of the opening 4 enters the groove portion 2 on the sash frame 1 side. By filling and foaming and curing the resin to form the resin cured body 8, for example, when the resin cured body 8 is melted due to a fire in a building and the fixing and holding function for the sash frame 1 disappears, the sash frame 1 Is lowered by its own weight with the progress of melting of the cured resin body 8, and further lowering is prevented by coming into contact with the lower inner surface 4b of the opening 4, and at a position near the upper portion of the sash frame 1. Movement (tilting) in the thickness direction of the sash frame 1 is restricted by the movement restricting action by the engagement between the development part 7b of the hinge body 7 and the side wall part 2b of the groove part 2, and as a synergistic effect thereof, the sash is Frame 1 is the opening It is disengaged and falling from be reliably prevented, so that safety in case of fire is ensured.

  Since the operations and effects other than those described above are the same as those in the case of the first embodiment, the corresponding portions are cited and the description thereof is omitted here.

D: Fourth Embodiment FIG. 12 shows a main part of a sash frame fixing method according to a fourth embodiment of the present invention. The basic method of the fixing method of this embodiment is the same as the fixing method of the first to third embodiments, and the difference is that it is provided on each of the left and right side wall surfaces 4c of the opening 4. It is the structure of the locking member 10 to be used.

  In each said embodiment, the member of the same kind structure was employ | adopted as the latching member 10 provided in each of the left-and-right side wall surface 4c of the said opening part 4. FIG. That is, in the first embodiment, the nail body 5 is attached as the locking member 10 to each of the left and right side wall surfaces 4c, and in the second embodiment, the plate body is used as the locking member 10 to each of the left and right side wall surfaces 4c. In the third embodiment, the hinge body 7 is attached as the locking member 10 to each of the left and right side wall surfaces 4c.

  On the other hand, in this embodiment, the locking member 10 provided on one side wall surface 4c of the opening 4 and the locking member 10 provided on the other side wall surface 4c are configured by members having different structures. . Specifically, as shown in FIG. 12, the plate body 6 used in the second embodiment is attached to one side wall surface 4c of the opening 4, and a third side wall surface 4c is attached to the third side wall surface 4c. The hinge body 7 used in the embodiment is attached.

  When the sash frame 1 is fitted into the opening 4, the projection 6 b of the plate body 6 is closer to the side wall surface 4 c than the side edge position of the sash frame 1, as shown by the chain line in FIG. The projecting portion 6b is bent and deformed so as to be positioned at the position, and the unfolded portion 7b of the hinge body 7 is positioned so that the developed portion 7b is closer to the side wall surface 4c than the side edge position of the sash frame 1. Is set to “Evacuation position”. In this state, the sash frame 1 is fitted into the opening 4.

  When the sash frame 1 is completely fitted into the opening 4, the plate body 6 faces the groove portion 2 on one side of the sash frame 1, and the hinge body 7 is connected to the sash frame 1. It faces the groove 2 on the other side. In this state, the plate body 6 is bent and deformed so that the protruding portion 6 b enters the groove portion 2. Further, the hinge body 7 expands the expanded portion 7b forward (inward of the opening) from the “retracted position” and enters the groove 2.

  Thereafter, as in the above embodiments, hard foamed urethane is injected and filled into the space 9 between the outer periphery of the sash frame 1 and the inner periphery of the opening 4, and this is foam-cured and cured. The hardened body 8 is used to block the space 9 with the resin hardened body 8 to ensure airtightness, and the sash frame 1 is fixedly held on the opening 4 side. Thus, the fixing operation of the sash frame 1 to the opening 4 is completed.

  In this way, the protruding portion 6b of the plate body 6 and the unfolded portion 7b of the hinge body 7 respectively attached to the left and right side wall surfaces 4c of the opening 4 are respectively inserted into the groove portion 2 on the sash frame 1 side. In this state, the space portion 9 is filled with the hard foamed urethane 8 and foamed and cured to obtain the resin cured body 8, so that the resin cured body 8 is melted due to, for example, a building fire and the sash frame When the fixing and holding function with respect to 1 disappears, the sash frame 1 falls by its own weight as the cured resin body 8 is melted, and the sash frame 1 is brought into contact with the lower inner surface 4b of the opening 4 so that a further drop is caused. On the other hand, at the position closer to the upper portion of the sash frame 1, the engagement between the protruding portion 6 b of the plate body 6 and the side wall portion 2 b of the groove portion 2, and the unfolded portion 7 b of the hinge body 7 and the groove portion 2. For engagement with the side wall 2b Thus, since the movement (tilting) of the sash frame 1 in the thickness direction is restricted, as a synergistic effect thereof, the sash frame 1 is reliably prevented from being detached and dropped from the opening 4, As a result, safety in the event of a fire is ensured.

  Since the operations and effects other than those described above are the same as those in the case of the first embodiment, the corresponding portions are cited and the description thereof is omitted here.

  In this embodiment, the left and right locking members 10 are configured as a combination of the plate body 6 and the hinge body 7, but the present invention is not limited to this. The stop member 10 can also be configured as a combination of the nail body 5 and the hinge body 7 used in the first embodiment.

E: Fifth Embodiment FIG. 13 shows the relative relationship between the sash frame 1 used for the sash frame fixing method according to the fifth embodiment of the present invention and the opening 4 provided in the concrete wall 3. Showing the relationship. The sash frame 1 is, for example, a vertically long and large sash frame used as a window frame of a sweep window, and its basic configuration is the same as the sash frame 1 in each of the above embodiments, and only the size thereof is different. In the state where the sash frame 1 is fitted in the opening 4 as in the case of the above embodiments, the locking member 10 provided on the side wall surface 4c of the opening 4 is attached to the sash. The frame 1 is inserted into the groove 2 and the movement of the sash frame 1 in the thickness direction is restricted by the engagement between the locking member 10 and the side wall 2b of the groove 2.

  The feature of the fixing method of this embodiment is that the sash frame 1 is fitted without any subsequent operation such as bending deformation on the locking member 10 attached to the side wall surface 4c of the opening 4. This makes it possible to simplify and speed up the fitting work. A prerequisite for the establishment of this fixing method is the torsional deformation tolerance unique to the large sash frame 1.

  That is, in the large sash frame 1A shown in FIG. 13, when the external force F in the opposite direction is applied to the upper corners of the sash frame 1A and twisted, the joints on each side of the sash frame 1 are slightly affected by the twisting force. The sash frame 1B as a whole causes torsional deformation about the center line in the width direction of the sash frame 1 as a whole. When such torsional deformation occurs, the width dimension of the sash frame (the dimension between the outer edges of the side wall portions 2b of the left and right groove portions 2 on the surface orthogonal to the sash frame thickness direction) changes, and torsional deformation occurs. While the width dimension of the previous sash frame 1A is “L1”, the width dimension “L2” of the sash frame 1B after torsional deformation is smaller than “L1”. The sash frame 1 is fitted into the opening 4 using the change in the width dimension caused by the torsional deformation of the sash frame 1. Hereinafter, the fitting operation | work to the said opening part 4 of this sash frame 1 is demonstrated.

  First, in this embodiment, both the nail body 5 used in the first embodiment and the plate body 6 used in the second embodiment can be used as the locking member 10. A plate body 6 is employed. In this case, the plate body 6 has a shape in which the fixing portion 6a and the protruding portion 6b are substantially orthogonal, as shown in an enlarged view in FIG. And this plate body 6 is fixed to the upper position of the left-right side wall surface 4c of the said opening part 4, and the protrusion part 6b is protruded inside an opening part (refer FIG. 14, FIG. 15). The plate body 6 is used in this attached state, and there is no subsequent processing operation such as bending deformation, so that the post-processing operation is omitted, so that the sash frame 1 is fitted. Workability is improved.

  Next, the sash frame 1 is inserted into the opening 4 in a state where the torsional force is applied to the sash frame 1 to cause torsional deformation (the state of the sash frame 1B in FIG. 13). Then, as described above, the width of the sash frame 1 is reduced due to torsional deformation. Therefore, as shown in FIG. 14, the sash frame 1 has a side wall portion 2b of the groove 2 and the plate body 6 as shown in FIG. Without interfering, the end of the plate body 6 passes through and is inserted into the opening 4 so that the groove 2 faces the plate body 6.

  When the plate body 6 faces the groove 2 and the torsional force applied to the sash frame 1 is released, the sash frame 1 returns to the original shape and its width increases, as shown in FIG. As described above, the protruding portion 6b of the plate body 6 enters the groove portion 2, and can be engaged with the side wall portion 2b of the groove portion 2 in the sash frame thickness direction. This completes the work of fitting the sash frame 1 into the opening 4.

  Therefore, after that, as in the case of the above embodiments, hard foamed urethane is injected and filled into the space 9 between the inner surface of the opening 4 and the outer peripheral surface of the sash frame 1, and this is foamed and cured. The resin cured body 8 is used, and the space 9 is closed by the resin cured body 8 to ensure the airtightness, and the sash frame 1 is fixedly held on the opening 4 side. Thus, the fixing operation of the sash frame 1 to the opening 4 is completed.

  In this state where the plate body 6 attached to the side wall surface 4c of the opening 4 is inserted into the groove 2 on the sash frame 1 side, the space 9 is filled with rigid foamed urethane 8, By foaming and curing the resin cured body 8, for example, when the resin cured body 8 is melted due to a building fire and the fixing and holding function for the sash frame 1 disappears, the sash frame 1 is cured with resin. As the body 8 is melted, its own weight is lowered, and further contact with the lower inner surface 4b of the opening 4 is prevented. Further, the plate body 6 is located at a position near the upper portion of the sash frame 1. The movement of the sash frame 1 in the thickness direction (tilt) is restricted by the movement restricting action caused by the engagement between the groove portion 2 and the side wall portion 2b. As a synergistic effect, the sash frame 1 is Withdrawal and fall Is reliably prevented, as a result, safety in case of fire is ensured.

  Since the operations and effects other than those described above are the same as those in the case of the first embodiment, the corresponding portions are cited and the description thereof is omitted here.
