Description

  The present invention relates to a frame fixing structure and a joinery.

  As a structure for fixing a window frame to a building frame such as RC (steel reinforced concrete), the present applicant has previously proposed the structure described in Patent Document 1. That is, a frame anchor member is provided in the opening of the building frame, while a frame anchor member is provided in the window frame, and the periphery of the frame anchor member and the frame anchor member is covered with a mold member, and then cured inside the mold member. This is a fixed structure in which the frame anchor member and the frame anchor member are coupled by filling and curing a coupling material made of a conductive resin material.

  By the way, when formally fixing the window frame to the building frame, after temporarily fixing with the above-described fixing structure, it is necessary to fill and harden a filler such as mortar between the opening of the building frame and the window frame. There is.

  Here, if the connecting material injected into the mold member and the filler filled around the window frame are the same material, there will be a problem even when the connecting material and the filler are thermally expanded. There is no. However, since the required conditions differ between the connecting material injected into the mold member and the filler filled around the window frame, different materials are often used. For example, the connection material injected into the mold member does not require a large connection strength, but it is preferable that the frame anchor member and the frame anchor member can be connected by curing as soon as possible, so there are many curable resin materials. Used. On the other hand, mortar and concrete are often used for the filler filled around the window frame because the connection strength after curing is preferably larger than the curing speed. Thus, in a fixing structure in which different materials are applied to the connecting material injected into the mold member and the filler filled around the window frame, the resin material generally used is used. Since the linear expansion coefficient is extremely larger than that of mortar, the appearance quality may be deteriorated by causing cracks and cracks in the filler when thermally expanded.

In the case of fixing the window frame (frame body) 20 to the opening 11 formed in the RC (steel reinforced concrete) building housing 10, the frame fixing structure exemplified here is a space between the building housing 10 and the window frame 20. Before formally fixing with a filler 70 such as mortar, the window frame 20 is temporarily fixed to the building frame 10 as shown in FIG. The window frame 20 has a rectangular frame shape formed by four-frames an upper frame member 21, a lower frame member 22, and a pair of left and right vertical frame members 23, 23. The opening 11 of the building housing 10 is formed in a rectangular shape large enough to accommodate the window frame 20. The window frame 20 is fixed to the opening 11 of the building frame 10 by a plurality of fixed structure units including a frame anchor member (first fixing member) 30, a frame anchor member 40, a mold member 50, and a connecting member 60. It is.

  As shown in FIG. 1, the frame anchor member 30 is a nail-shaped member having a large-diameter head portion 32 at the base end portion of the shaft portion 31 with a sharp tip, and the tip portion is embedded in the building housing 10. It protrudes from the inner peripheral surface of the opening 11 in a state. A collar member 33 formed of a resin material is attached to a portion of the shaft portion 31 of the housing anchor member 30 that protrudes from the building housing 10. The collar member 33 is a deformed cylindrical member whose outer peripheral surface in the central portion in the axial direction is recessed.

  As shown in FIGS. 1 and 4, the frame anchor member 40 is bent in an out-of-plane direction of the substrate portion 41 from one long side side edge portion of the substrate portion 41 in a substantially rectangular flat plate shape. The support portion (second fixing member) 42 extending in this manner is integrally formed. The support portion 42 has only a portion whose base end portion extends along the long side of the substrate portion 41, while the tip portion extends along the portion and the long side where the distal end portion extends along the short side of the substrate portion 41. An L-shaped cross section having an extending portion is formed.

  A screw hole 41a is formed at the center of the substrate portion 41, and an engagement piece 43 is formed at each central portion of the short side edge. The screw hole 41a is a through-hole having a screw groove on the inner peripheral surface, and for example, a bolt member 140 that is longer than the support portion 42 can be detachably attached thereto. The engagement piece 43 is a portion that once bends from the base plate portion 41 toward the opposite side of the support portion 42 and then extends in a direction away from each other, and between the base plate portion 41 and the window frame 20. The gap | interval which can clamp the protrusion 20a is comprised. As shown in FIG. 1, the projecting piece 20 a of the window frame 20 is a portion that extends in the direction close to each other after extending from the respective finding surfaces of the frame members 21, 22, and 23 toward the outer peripheral direction. The frame members 21, 22, and 23 are formed over the entire circumference. The distance between the tips of the projecting pieces 20 a is shorter than the long side of the substrate portion 41. As is clear from FIG. 4, the substrate portion 41 and the engagement piece 43 are formed with notched inclined surfaces 41 b and 43 a that are parallel to each other and that are inclined with respect to the long side of the substrate portion 41. It is. These notched inclined surfaces 41 b and 43 a are configured such that the distance between them is slightly shorter than the distance between the projecting pieces 20 a formed on the window frame 20.

  In the frame anchor member 40 having the above-described configuration, the base plate portion 41 is inserted between the tips of the projecting pieces 20a with the notched inclined surfaces 41b and 43a being parallel to the tip edges of the projecting pieces 20a. , The frame anchor member 40 is rotated clockwise, and is attached to the outer peripheral surface of the window frame 20 with the projecting pieces 20a sandwiched between the base plate portion 41 and the engaging pieces 43, respectively. As is clear from FIGS. 1 and 2, the length of the support portion 42 of the frame anchor member 40 is set so as to overlap with the distal end portion of the frame anchor member 30 in a state of being attached to the window frame 20. It is.

  As shown in FIGS. 1 and 5, the mold member 50 has a bottom wall portion 52 at one end of a base portion 51 having a circular cross section, and the other end of the base portion 51 is opened. In the present embodiment, the base part (absorbing part) 51 and the bottom wall part (absorbing part) 52 of the mold member 50 are integrally molded with rubber which is an elastic member. When an external force is applied along the plate thickness direction, the base portion 51 and the bottom wall portion 52 of the mold member 50 can be contracted in the plate thickness direction by elastically deforming. The rubber constituting the mold member 50 can maintain its shape even when the periphery of the mold member 50 is filled with the filler 70, and the plate thickness even after the filler 70 is cured. It is necessary to apply one that can maintain the shrinkage in the direction.

  As is apparent from the figure, the base 51 of the mold member 50 gradually increases in diameter from one end having the bottom wall portion 52 toward the other end, and the outer shape forms a truncated cone shape. Yes. The mold member 50 has a mounting hole 52 a formed in the bottom wall 52 and an injection hole 51 a formed in the base 51. The mounting hole 52 a is an L-shaped through hole that can be fitted into the support portion 42 of the frame anchor member 40, and the injection hole 51 a is a circular opening that penetrates the base portion 51 of the mold member 50.

  As shown in FIG. 1, the mold member 50 is attached to the support portion 42 by inserting the support portion 42 of the frame anchor member 40 through the attachment hole 52a. It arrange | positions in the state which covers the circumference | surroundings of the frame anchor member 30. FIG. The mold member 50 is slidable in the extending direction with respect to the support portion 42, and is disposed at a position where the open end surface of the base portion 51 is in contact with the inner peripheral surface of the opening portion 11 in the building housing 10. Yes. When the mold member 50 slides along the extending direction of the support portion 42, the circumferential direction of the mold member 50 is changed because the cross section of the support portion 42 is configured in an L shape. There is nothing.

  The connecting member 60 is a solid member filled in the mold member 50, and maintains the state in which the frame anchor member 30 and the support portion 42 of the frame anchor member 40 are connected in the mold member 50. Yes. The connecting material 60 is made of a synthetic resin having aging, thermosetting, or thermoplasticity, and has fluidity in a non-cured state and has a mold when injected into the mold member 50. It exhibits an indefinite shape having a viscosity sufficient to remain inside the member 50. On the other hand, the connection material 60 in a cured state expresses strength for maintaining the state in which the frame anchor member 30 and the support portion 42 of the frame body anchor member 40 are connected.

  Hereinafter, the procedure for fixing the window frame 20 to the opening 11 of the building housing 10 by applying the frame fixing structure described above will be described with reference to FIGS. 6-1, 6-2, 6-3, and 6-4. The description will be given with appropriate reference.

  In this frame body fixing structure, as shown in FIG. 6A, first, the anchor member 30 is protruded from each of a plurality of desired positions on the inner peripheral surface of the opening 11.

  Next, the window frame 20 is built in the opening 11 of the building housing 10 on which the housing anchor member 30 is projected. The window frame 20 built in the opening 11 is a state in which an upper frame member 21, a lower frame member 22, and a pair of left and right vertical frame members 23, 23 are in a four-round framework.

  Next, as shown in FIG. 6B, the frame anchor member 40 is attached to the portion corresponding to each frame anchor member 30 in the window frame 20 built in the opening 11 of the building frame 10, thereby the frame anchor member. 30 and the support part 42 of the frame anchor member 40 are overlapped in a state where they are juxtaposed with each other. When attaching the frame anchor member 40 to the window frame 20, the mold member 50 is attached to the support portion 42 in advance with the bottom wall portion 52 facing the substrate portion 41. At this time, as shown in FIG. 6B, the mold member 50 is arranged in the state of being close to the base plate portion 41 so that the mold member 50 and the frame anchor member 30 do not interfere when the window frame 20 is installed. It is preferable to make it. In addition, the orientation of the mold member 50 with respect to the support portion 42 is preferably adjusted so that the injection hole 51a of the mold member 50 is disposed on the front side.

  Next, as shown in FIG. 6-3, the mold members 50 are each slid relative to the support portion 42 so as to be close to the building housing 10, and the opening end surface of the base 51 of the mold member 50 is brought into contact with the building housing 10. Thus, the protruding end portions of the housing anchor member 30 are accommodated in the mold members 50 in a state where the base portion 51 covers the periphery of the support portion 42 and the housing anchor member 30.

  Thereafter, the uncured coupling material 60 is injected into each mold member 50 from the injection hole 51 a to fill the interior of the mold member 50. At this time, even when the mold member 50 is slid with respect to the support portion 42, in order to maintain the state where the position of the injection hole 51a is disposed on the near side, the operation of injecting the connecting material 60 is performed while visually observing. Can do. Accordingly, the connecting material 60 can be injected into all the mold members 50 without excess and deficiency, and the injection amount of the connecting material 60 filled in the mold member 50 can be easily made uniform at a plurality of locations. .

  If the connecting member 60 is cured in the above-described state, a predetermined strength is developed in the connecting member 60, and the housing anchor member 30 and the support portion 42 of the frame anchor member 40 are maintained in a connected state. Can do. That is, the window frame 20 can be fixed to the opening 11 of the building frame 10 via the frame anchor member 30 and the support 42 of the frame anchor member 40 connected to each other by the cured connection material 60. . In this case, in the above-described embodiment, since the support portion 42 of the frame anchor member 40 and the distal end portion of the frame anchor member 30 overlap each other in the mold member 50, It is possible to improve the connection strength compared to the case where these do not overlap.

  Finally, as shown in FIG. 1, if a backup material B is appropriately installed between the opening 11 of the building housing 10 and the window frame 20, and a filler 70 such as mortar is filled from this state, FIG. As shown in FIG. 4, the window frame 20 can be formally fixed to the opening 11 of the building housing 10.

  According to the frame fixing structure described above, since welding work is not required when fixing the window frame 20 to the opening 11 of the building housing 10, work for preparing equipment such as power supply facilities, and building from heat and sparks. Therefore, it is not necessary to install a curing for protecting the interior and exterior of the machine, so that the workability can be improved and the work cost can be reduced. The frame anchor member 30 and the frame anchor member 40 do not need to be formed of metal, and the effect of improving the degree of freedom in material selection is also achieved.

  In addition, since the connecting member 60 that connects the frame anchor member 30 and the frame anchor member 40 assumes an indefinite shape in the non-cured state, the positional deviation between the frame anchor member 30 and the frame anchor member 40 is absorbed. Both can be fixed. In particular, in the above-described frame fixing structure, the periphery of the frame anchor member 30 and the frame anchor member 40 is covered with the mold member 50, and the opening end surface of the base 51 is brought into contact with the building frame 10, so that the mold As long as the connecting member 60 is injected into the member 50, the injection amount can be made uniform at a plurality of locations without requiring a complicated operation. As a result, the window frame 20 can be fixed to the opening 11 of the building frame 10 in a state where the connection strength with the building frame 10 is equal over the entire periphery of the window frame 20, and a glass window or the like is provided inside the window frame 20. If a shoji (not shown) is arranged, a desired joinery can be installed in the building frame 10. In addition, since the connecting material 60 is injected into the mold member 50, it is possible not only to prevent the connecting material 60 from flowing out during the injection regardless of the orientation of the mold member 50, but also to cure. In the meantime, the connecting member 60 can be securely fastened between the frame anchor member 30 and the frame anchor member 40.

  Furthermore, since the frame anchor member 40 is formed by integrally forming the base plate portion 41 and the support portion 42, it is possible to reduce the number of parts, improve workability, and reduce manufacturing costs. It becomes. In addition, since the screw hole 41a into which the bolt member 140 can be screwed is formed in the board portion 41, the gap between the inner peripheral surface of the opening 11 formed in the building housing 10 and the window frame 20 is large. It is possible to apply the same frame anchor member 40 to a location.

  Furthermore, since the mold member 50 is made of rubber, the mold member 50 contracts in the plate thickness direction due to the difference in coefficient of linear expansion between the connecting material 60 and the filler 70 when thermally expanded. Will be alleviated. That is, since the linear expansion coefficient of the connecting material 60 is extremely larger than that of the filler 70, the volume increase rate of the connecting material 60 is larger than that of the filler 70 when the temperature rises. As a result, when a mold member is merely interposed between the connecting material 60 and the filler 70, the volume of the connecting material 60 may increase the appearance quality such as cracks and cracks in the filler 70. Can do.

  However, according to the above-described frame fixing structure, since the mold member 50 that contracts in the plate thickness direction is applied, even when it thermally expands from the state shown in FIG. As shown in (b), the mold member 50 becomes an absorbing portion, and the volume increase of the connecting member 60 is absorbed and relaxed, and the influence of the influence on the filler 70 is eliminated. As a result, it is possible to prevent occurrence of a situation in which the appearance quality is deteriorated such as a crack or a crack in the filler 70. Incidentally, when the temperature of the connecting member 60 decreases and contracts, the mold member 50 returns to the original state by the elastic restoring force. Therefore, even when the connecting member 60 is thermally expanded again, the volume increase is absorbed and relaxed by the mold member 50 again.

  In the above-described embodiment, an RC building is illustrated as an example of the building frame. However, it is not necessarily limited to an RC building, but a wooden one, a cement-molded plate, an ALC (Autoclaved Lightweight Aerated Concrete) plate, or the like. It is also possible to apply to other things.

  In the above-described embodiment, the mold member 50 is held by the frame anchor member 40, which is the second fixing member, but may be held by the first fixing member.

  Furthermore, in the above-described embodiment, the frame anchor member 30 is provided by being driven into the building frame 10, but the present invention is not necessarily limited to this. It is possible to apply as a member. For example, if a part of a reinforcing bar or steel bar embedded in a building frame is exposed to the outside, this can be applied as a frame anchor member. In this case, the operation of driving the frame anchor member 30 into the building frame 10 can be omitted, and the operation can be further facilitated.

  Furthermore, in the above-described embodiment, the mold member 50 has a circular cross section and a truncated cone shape. However, as long as it has a cylindrical shape, it may have other cross sectional shapes. Of course, a uniform cross-sectional shape may be applied.

  Moreover, in embodiment mentioned above, what was shape | molded with rubber | gum as a type | mold member is illustrated, However, This invention is not limited to this, The absorption part which can be shrunk | reduced in the plate | board thickness direction is provided after hardening of a filler. Others may be used as long as they can be used.

  For example, in the first modification shown in FIG. 8, as shown in FIGS. 8A and 8B, the base portion 151 of the mold member 150 has a hollow shape having an outer peripheral wall portion 151a and an inner peripheral wall portion 151b. doing. The outer peripheral wall portion 151a and the inner peripheral wall portion 151b can maintain their respective shapes even when the periphery of the outer peripheral wall portion 151a is filled with the filler 70, and even after the filler 70 is cured, the plate Each is formed of a resin material so that the shrinkage in the thickness direction can be maintained.

  In the second modification shown in FIG. 9, as shown in FIGS. 9A and 9B, the base portion 251 of the mold member 250 has a hollow shape having an outer peripheral wall portion 251a and an inner peripheral wall portion 251b. Further, the outer peripheral wall portion 251a and the inner peripheral wall portion 251b are bonded to each other by a core portion 251c having a wave shape. The outer peripheral wall portion 251a, the inner peripheral wall portion 251b, and the core portion 251c can maintain their respective shapes even when the periphery of the outer peripheral wall portion 251a is filled with the filler 70, and the filler 70 is cured. Afterwards, each is molded with a resin material so that the contractibility in the thickness direction can be maintained.

  When the mold members 150 and 250 of the first and second modified examples are applied, the connecting material 60 in contact with the inner peripheral wall portions 151b and 251b and the filler 70 in contact with the outer peripheral wall portions 151a and 251a are thermally expanded. In this case, as shown in FIG. 8C or FIG. 9C, the inner peripheral wall portions 151b and 251b expand, but form a hollow layer between the outer peripheral wall portions 151a and 251a. The absorption layers (absorption portions) 152 and 252 are reduced, and this is absorbed. In addition, since the absorbing layers 152 and 252 can be secured more easily and larger than the mold member 50 of the first embodiment formed of rubber, the filler 70 is expanded by the expansion of the connecting material 60. The influence can be prevented more reliably. Furthermore, in the second modified example, the expansion of the inner peripheral wall portion 251b is suppressed by the middle core portion 251c, and the influence on the filler 70 can be suppressed more reliably than in the first modified example. Further, the absorbing portion of the mold member can be configured by attaching or winding an elastic member such as urethane sponge around the surface of a reference member. The elastic member may be provided only on one side surface of a reference member or on both side surfaces.

  In the above-described embodiment, it is assumed that the linear expansion coefficient of the connecting material 60 is larger than that of the filler 70, but even if the linear expansion coefficient of the connecting material is smaller than that of the filler. It is possible to respond.
