Description

  The present invention relates to a fitting that is attached to an opening such as an entrance and exit disposed on a partition wall and that can suppress the occurrence of warpage even if there is a difference in temperature, humidity, or the like in the space on both sides thereof, and can maintain good construction. .

  An indoor joinery used for a partition opening causes a large temperature difference between a room heated in winter and a corridor on the opposite side, for example. Furthermore, the air on the side of the room to be heated dries, and a significant difference is also produced in the humidity on both sides. Similarly, during summer cooling, large differences in temperature and humidity occur on both sides of the joinery.

  On the other hand, a flash structure joiner with a decorative plate attached to both sides of a wooden panel frame that is formed with a reinforcing frame on the inside of an outer peripheral frame in which a vertical frame material and a horizontal frame material are framed in a rectangular shape. It is widely used because it can be manufactured at low cost, and its design has been greatly improved with the development of materials and processing technology. However, in such a flash structure joinery, when the temperature and humidity difference occurs on both sides as described above, the decorative plates on both sides cause different expansion and contraction, so that the so-called bimetal action tends to cause warpage. there were.

  Therefore, the present applicant attaches a moisture-proof sheet formed by laminating paper on both sides of a plastic film (polyethylene, etc.) to the decorative plate, so that even when there is a temperature difference between both sides of the decorative plate, Has proposed a fitting that can suppress the difference in moisture content and prevent warping as a result (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 9-235954

  In this joinery, although the gap in moisture content change due to humidity difference can be suppressed, there is a difference in elongation due to temperature difference, so it is difficult to completely suppress warpage, and a moisture proof sheet with paper laminated on both sides, The number of man-hours to be adhered to both sides of the decorative board has increased, and it has been difficult to process the joinery, resulting in problems such as an increase in manufacturing cost, and further improvements have been desired.

  The present invention is basically provided with a gap absorbing portion capable of absorbing the positional deviation between the collar frame and the surface plate caused by the expansion and contraction of the surface plate, and the temperature on both sides, such as when the living room on one side is heated and cooled. It is an object of the present invention to provide a fitting that can maintain good construction without causing warpage even when the humidity changes separately and a difference in expansion and contraction occurs between the surface plates on both sides.

  In order to achieve the above object, the invention according to claim 1 is a joinery comprising a joinery frame and a surface plate attached to both sides of the joinery frame, wherein the joinery frame is arranged on both sides. The surface is configured to have a rectangular shape having a pair of rib frames, an upper frame spanned between the upper end portions of the rib frame, and a lower frame spanned between the lower end portions of the rib frame, The material is attached to the joinery frame by supporting both sides of the frame on the left and right frame, and this frame can absorb the displacement of the frame and surface plate caused by the expansion and contraction of the surface plate. A portion is provided.

  In the invention which concerns on Claim 2, while the said surface plate is affixed to a collar frame via the butyl tape in the both sides, the said shift | offset | difference absorption part is formed with this butyl tape, In the invention which concerns on Claim 3 The butyl tape has a thickness of 0.5 to 5.0 mm, and in the invention according to claim 4, the upper frame and the lower frame are formed such that the thickness direction of the joinery is larger than the frame. A step is generated between the surface and the surface of the eaves frame, and the butyl tape has a thickness substantially the same as the step.

  In the invention according to claim 5, the joinery frame is provided with a horizontal reinforcing intermediate beam between the upper frame and the lower frame, and one of the upper frame, the lower frame, and the reinforcing intermediate beam is the above table. In the invention according to claim 6, which is bonded to the face plate, the frame has an elastic layer in the middle of the thickness direction of the joinery, and the displacement absorbing portion is formed by this elastic layer.

  In the invention according to claim 1, even when the temperature and humidity of the indoor spaces on both sides change separately and cause a difference, such as during heating in winter, even if the surface plates on both sides expand and contract at different ratios, the surface material The right and left saddle frames that support both sides of the frame are provided with a gap absorbing portion that can absorb the positional deviation between the saddle frame and the surface board caused by the expansion and contraction of the surface plate. It is possible to maintain a good construction.

  As in the invention according to claim 2, when both sides of the surface plate are attached to the eaves frame via the butyl tape, the stress due to the difference in expansion and contraction is relieved by the adhesive displacement action having good adhesiveness to the butyl tape. Therefore, the warpage of the joinery is effectively suppressed, and when a butyl tape having a thickness of 0.5 to 5.0 mm is used as the displacement absorbing portion as in the invention according to claim 3, it is necessary in a normal use state. In addition, since a sufficient displacement absorbing action is obtained, the occurrence of warpage can be effectively prevented.

  As in the invention according to claim 4, by forming the thickness direction of the upper frame and the lower frame larger than the frame, the butyl tape is accommodated between the surface of the frame and the surface of the frame. If it is configured to provide a possible step, it is possible to prevent gaps between the upper frame, the lower frame, and the surface plate, and to form a fitting that is free of rattling and has a good appearance, and as in the invention according to claim 5 In addition, when the surface plate is bonded to one of the upper frame, the lower frame, and the reinforcing middle beam, the surface plate supported by the deviation absorbing portion can be prevented from being displaced downward by its own weight. Further, as in the invention according to claim 6, when the displacement absorbing portion is formed by the elastic layer provided in the middle of the frame thickness direction of the frame, since it is excellent in appearance and exhibits a stable displacement absorbing action, the warp is warped. It can be surely suppressed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the joinery 1 is configured as a flush-structured panel including a joinery frame 2 constituting a skeleton and a pair of surface plates 3 attached on both sides thereof.

  The surface plate 3 has a rectangular thin plate shape and is arranged in parallel with the joinery frame 2 interposed therebetween, and at least the surface side is configured as a decorative surface. This surface plate 3 is a veneer obtained by slicing oak, cherry, teak, zelkova, etc. into about 0.2 to 0.6 mm on a substrate such as plywood, or an olefin type such as polyethylene, polypropylene, ethylene vinyl acetate resin (EVA). A decorative board to which a decorative sheet using a resin, a melamine resin, or a polyester resin is attached can be suitably used. However, other plastic plates such as polyethylene resin, polypropylene resin, polystyrene resin, phenol resin, unsaturated polyester resin, steel materials including carbon steel, stainless steel, alloy steel, or metal plates such as aluminum, brass, copper, titanium, etc. It can also be used.

  As shown in FIG. 3, the joinery frame 2 includes a frame 4, 4 disposed on both sides, an upper frame 5 spanned between the upper ends of the frame 4, 4, and a lower end. Including the lower frame 6 that has been passed, it has a rectangular shape. In the present embodiment, a plurality of reinforcing middle bars 9 are further provided at equal intervals between the upper and lower frames 5 and 6 to reinforce the joinery 1.

  In this embodiment, as shown in FIG. 4, the upper frame 5 and the lower frame 6 are formed such that the dimension in the thickness direction of the fitting 1 is larger than that of the eaves frame 4, and as a result, the surfaces of the upper frame 5 and the lower frame 6. And a step of about several millimeters is formed between the surface of the collar frame 4.

  The joinery frame 2 is made of solid wood including conifers such as cedar, pine, firewood and firewood, and hardwood such as oak, teak and lauan, or wood-processed bars such as laminated timber and LVL (single veneer). It can be used suitably. In addition, various plastic materials and metal materials can be used.

  The surface plate 3 is superimposed on the joinery frame 2 and, in this embodiment, is attached to the frame frame 4 via a butyl tape 8. Since the butyl tape 8 has viscoelasticity, the butyl tape 8 has a deformation follow-up ability, and forms a displacement absorbing portion 7 that can absorb a displacement between the collar frame and the surface plate. Accordingly, even if the temperature and humidity of the indoor space on both sides of the joinery 1 change separately during heating in winter, etc., even if the surface plates 3 on both sides expand and contract at different ratios, this expansion / contraction difference is not detected by the displacement absorbing portion 7. Therefore, the fitting 1 is not warped and can maintain a good construction. Moreover, since the butyl tape 8 used in this embodiment has a soft viscoelasticity, it exhibits a good displacement absorbing action, and even if a large difference in expansion and contraction occurs, the stress is relieved. Can be reliably suppressed.

  The thickness of the butyl tape 8 is, for example, about 0.5 to 5.0 mm, preferably 1.5 mm to 3.5 mm, and 2.5 mm in this embodiment. If the thickness is less than 0.5 mm, the displacement cannot be sufficiently absorbed, which may cause warpage. Conversely, if the thickness exceeds 5.0 mm, the displacement absorption capacity becomes excessive, and the butyl tape 8 protrudes. It is easy to damage.

  Further, in this embodiment, since a step is provided between the surface of the gutter frame 4 attached to the surface plate 3 via the butyl tape 8 and the upper and lower frames 5, 6, the butyl tape 8 is in the step. Can be formed, and the end portion of the surface plate 3 is not pushed by the thickness of the butyl tape 8 so that the warp does not occur and the butyl tape 8 does not protrude, so that the fitting 1 excellent in appearance can be formed. .

  Furthermore, in this embodiment, the back surface of the front plate 3 is fixed to one of the reinforcing middle bars 9 using an adhesive. Even if impact vibration or the like is applied by this adhesive force, the surface plate 3 supported by the deviation absorbing portion 7 is prevented from being displaced downward by its own weight. The surface plate 3 may be bonded to either the upper frame 5 or the lower frame 6 in place of the reinforcing middle rail 9.

  FIG. 5 illustrates another embodiment. Hereinafter, different contents will be described, and other than that, only the same reference numerals are given to the main components shown in the figure. In the frame frame 4 of this embodiment, the elastic layer 10 is laminated in a sandwich shape between the frame frame pieces 21 and 21 divided into two layers in the thickness method of the joinery 1, and the frame frame piece 21 and the elastic layer 10 are bonded. It is formed integrally. As described above, in this embodiment, the displacement absorbing portion 7 is formed by the elastic layer 10 rich in deformability, and the elastic layer 10 exhibits a stable displacement absorbing action while being excellent in appearance, so that the warping of the fitting 1 is surely suppressed. it can.

  The elastic layer 10 is, for example, about 1.0 to 10.0 mm, preferably 3.0 to 7.0 mm, and 5.0 mm in this embodiment. If it is less than 1.0 mm, there is a risk of warping because the ability to absorb misalignment tends to be insufficient. Conversely, if it exceeds 10.0 mm, the capacity to absorb misalignment becomes excessive and the rigidity of the joinery frame 2 is insufficient. there's a possibility that.

  Elastic layer 10 is made of chloroprene rubber (CR), styrene / butadiene rubber (SBR), rubber containing isoprene rubber (IR), styrene / olefin / urethane / polyester and other thermoplastic elastomers, ethylene vinyl acetate copolymer It is formed using an elastic material such as coalescence (EVA).

  The above description is an example of the embodiment of the present invention. Therefore, the technical scope of the present invention is not limited to this, and various modifications are included in addition to the above-described embodiment.
