Description

  The present invention relates to a synthetic resin hollow panel suitable for applications such as daylighting outer wall materials, and more particularly to a synthetic resin hollow panel having an improved reinforcing material inserted into a hollow portion of the panel.

  In recent years, hollow panels manufactured by extruding translucent resins have been used as daylighting outer wall materials after a reinforcing material is inserted into the hollow portion to increase the strength. As such a hollow panel, for example, a polycarbonate resin hollow panel in which a metal reinforcing plate is inserted into a hollow portion on the side edge of the panel is known.

Also in the field of furniture shelf boards, etc., synthetic resin hollow plates (Patent Documents 1 and 2) in which a U-shaped metal reinforcing material is inserted into the hollow portion, and elastically expand into the hollow portion. A synthetic resin hollow plate (Patent Document 3) in which a metal reinforcing material having a substantially V-shaped cross section is inserted has been proposed.

  However, since the hollow panel and the hollow plates of Patent Documents 1 to 3 are all inserted into the hollow portion with a reinforcing material having a dimension corresponding to the hollow portion, the insertion work is not easy. When a reinforcing material having a size slightly smaller than that of the hollow portion is inserted for easy insertion, there is a problem in that the reinforcing material rattles in the hollow portion.

  In particular, long extruded panels with a small wall thickness, such as synthetic resin hollow panels used as daylighting exterior wall materials, have many variations in the dimensions of the hollow part. When inserting a reinforcing material of a scale, the tip of the reinforcing material is caught on the inner surface of the hollow portion, and there is a problem that the inserting operation is difficult. In addition, when a reinforcing material such as a metal plate is inserted into the hollow portion of such a hollow panel, heat is conducted between the front and back surfaces of the hollow panel through the metal plate, so that the portion reinforced with the metal plate is the original part of the hollow panel. When the outdoor air temperature is lowered, for example, there is a problem that condensation occurs on the indoor surface of the hollow panel.

  The present invention has been made under the above circumstances, and the problem to be solved is that the work of inserting the reinforcing material into the hollow portion is easy, and the reinforcing material causes rattling in the hollow portion. An object of the present invention is to provide a synthetic resin hollow panel that does not have a concern that the heat insulating property of the resin is impaired.

  In order to solve the above problems, a synthetic resin hollow panel according to the present invention is a hollow panel having a plurality of hollow portions penetrating in the panel length direction between a panel surface layer and a panel back surface layer. The main reinforcing material and the auxiliary reinforcing material are inserted into at least one hollow portion, and the main reinforcing material and the auxiliary reinforcing material are combined.

  In the synthetic resin hollow panel of the present invention, the cushioning material attached to a part of the outer surface of the main reinforcing material over the entire length of the main reinforcing material may be brought into close contact with either the panel surface layer or the panel back surface layer. preferable. And it is preferable to use the heat insulation buffer material which has heat insulation as a buffer material, and to make this heat insulation buffer material closely_contact | adhere to a panel surface layer.

  Moreover, in the synthetic resin hollow panel of the present invention, a concave streak is formed on one of the main reinforcing member and the sub reinforcing member, and the convex streak that can be fitted to the concave streak is on the other side. It is preferable to form the main reinforcing material and the auxiliary reinforcing material by combining the main reinforcing material and the auxiliary reinforcing material. In that case, the ridge portion is formed in an open cylindrical shape capable of expanding the diameter, and a screw is screwed into this ring-opened cylindrical ridge portion, or a rod is press-fitted, and the outer surface of the ridge portion is recessed. More preferably, it is pressed against the inner surface of the strip.

  Furthermore, in the synthetic resin hollow panel of the present invention, it is preferable to form convex ribs on the outer surface of at least one of the main reinforcing material and the auxiliary reinforcing material, and the main reinforcing material and the auxiliary reinforcing material are metal. It is preferably a hollow reinforcing material provided with an air core portion through which the main reinforcing material penetrates in the length direction.

  In the synthetic resin hollow panel of the present invention, the main reinforcing material is first inserted into the hollow portion, and then the auxiliary reinforcing material is inserted into the hollow portion and united with the main reinforcing material. Compared to the case where a single reinforcing material integrated with is inserted into the hollow portion, the main reinforcing material and the auxiliary reinforcing material can be inserted more easily. When the buffer material attached to the main reinforcing material is brought into close contact with either the panel surface layer or the panel back surface layer, the buffer material absorbs backlash in the hollow portion of the combined main reinforcing material and sub reinforcing material. Is done. In particular, even if the main reinforcing material and the sub-reinforcing material are metal reinforcing materials, the heat insulating buffering material having a heat insulating material as the buffering material is used to closely contact the panel surface layer. The heat conduction through the combined main reinforcement and sub-reinforcement is cut off, and the original heat insulation of the hollow panel is ensured. Therefore, even when the outside air temperature falls, condensation is formed on the back surface (indoor side surface) of the hollow panel It does not occur.

  Also, the main stiffener and sub-reinforcing material are combined by fitting the convex streaks formed on the other stiffener to the concave streaks formed on one of the main stiffener and sub-reinforcement. In order to maintain a certain united shape without causing positional displacement or separation between the main reinforcing material and the auxiliary reinforcing material, as in the case where the main reinforcing material and the auxiliary reinforcing material are simply brought into contact with each other, The strength of the hollow panel can be improved by exhibiting a stable reinforcing action. In particular, the ridge is formed into an open cylindrical shape capable of expanding the diameter, and a screw is screwed into the ridge of the open cylindrical shape, or a rod is press-fitted, and the outer surface of the ridge is recessed. When the ring-shaped cylindrical ridges are expanded, the apparent cross-sectional area of the reinforcing material increases and the bond between the main reinforcing material and the secondary reinforcing material becomes stronger. Because the strength is improved, it has substantially the same bending strength and bending strength as the case where the main reinforcing material and the auxiliary reinforcing material are integrally formed from the beginning, and greatly improves the strength of the hollow panel. At the same time, the backlash between the hollow portion and the reinforcing material can be further reduced.

  In the case where a convex rib is formed on the outer surface of at least one of the main reinforcing material and the auxiliary reinforcing material, the protruding rib substantially contacts the inner surface of the hollow portion of the panel when the reinforcing material is inserted. Since the outer surface of the reinforcing material does not easily come into surface contact with the inner surface of the hollow portion, the frictional resistance is reduced, and the reinforcing material can be more easily inserted and inserted. Further, when the main reinforcing material and the auxiliary reinforcing material are metal reinforcing materials and the main reinforcing material is a hollow reinforcing material having an air core portion penetrating in the length direction, the main reinforcing material is a hollow reinforcing material. It is also possible to reduce the weight of the hollow panel and reduce the material of the reinforcing material.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  1 is a partial perspective view of a synthetic resin hollow panel according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the hollow panel, and FIG. 3A is a partial perspective view of a main reinforcing member of the hollow panel. (B) is a fragmentary perspective view of the sub-reinforcement material of the hollow panel.

  This hollow panel P is obtained by extruding a lightly colored translucent resin, and as shown in FIG. 2, vertical, horizontal and diagonal partition walls 1c between the panel surface layer 1a and the panel back surface layer 1b. , 1d, 1e are formed, so that many hollow portions 2 penetrating in the panel length direction are formed. And, on one side surface of this hollow panel P, a hollow connecting ridge portion 1f whose tip side is slightly expanded is formed over the entire length of the panel, and on the opposite side surface, the above connecting ridge portion is formed. A connecting recess 1g having a shape corresponding to the portion 1f is formed over the entire length of the panel. Therefore, the hollow panels P can be easily connected to each other by press-fitting the connecting convex strips 1f into the connecting concave strips 1g of the adjacent hollow panels.

  As the translucent resin used as the raw material of the hollow panel P, translucent resins such as polycarbonate resin, acrylic resin, vinyl chloride resin, and polyester resin are preferably used. Among them, polycarbonate resin has impact strength. Since it is large, it is particularly preferably used. When manufacturing the hollow panel P with this polycarbonate resin, it is desirable to prevent yellowing and quality deterioration by ultraviolet rays by subjecting the surface of the panel surface layer 1a to weathering. Moreover, the resin used as a raw material may be colored or opaque in a state of maintaining translucency depending on the purpose and design, and an embossed pattern or the like may be provided on the surface of the hollow panel.

  A main reinforcing member 3 made of metal such as aluminum and a sub-reinforcing member 4 are inserted into the hollow portion 2 on the side edge of the hollow panel P where the connecting ridge portion 1f is formed. The reinforcing material 3 and the sub-reinforcing material 4 are combined so as to be described later and have a shape substantially corresponding to the shape of the hollow portion 2.

  As shown in FIGS. 2 and 3A, the main reinforcing member 3 is a metal hollow reinforcing member having an air core portion 3a penetrating in the length direction, and is the main reinforcing member on the panel surface layer 1a side. A mortise groove 3b is formed on the side surface of the reinforcing member 3 over the entire length. By fitting the tenon of the heat insulating cushioning material 5 into the tenon groove 3b, the heat insulating cushioning material 5 becomes the entire length of the main reinforcing member 3. It is attached over. The heat insulating cushioning material 5 blocks heat conduction between the panel surface layer 1a and the panel back surface layer 1b through the main reinforcing material 3 and the auxiliary reinforcing material 4, and also the main reinforcing material 3 and the auxiliary reinforcing material. 4 which plays the role of preventing rattling of, for example, ethylene-propylene-diene copolymer (EPDM), styrene-butadiene rubber, butadiene rubber, butyl rubber, chlorobrene rubber, nitrile rubber, acrylic rubber, silicone rubber Such as rubber, polyurethane elastomer, polystyrene elastomer, polyvinyl chloride elastomer, polyolefin elastomer, polyester elastomer, polyamide elastomer, etc. Are preferably used.

  Further, a concave strip portion 3c is formed on the side surface of the main reinforcing member 3 on the side of the panel back layer 1b over the entire length of the main reinforcing member 3, and the concave strip portion 3c has a full length of the auxiliary reinforcing member 4. The main reinforcing member 3 and the auxiliary reinforcing member 4 are combined so that the protruding portion 4a formed over the base member 4a is not separated or displaced. Further, the main reinforcing material 3 and the auxiliary reinforcing material 4 combined on the both sides of the protruding portion 4a of the auxiliary reinforcing material 4 are prevented from being bent into a "<" shape around the protruding item portion 4a. Anti-bending protrusions 4 c and 4 c are formed, and the anti-bending protrusions 4 c and 4 c are in contact with both side edges of the concave strip portion 3 c of the main reinforcing member 3.

  As shown in FIG. 3 (a), the ridge portion 4a of the auxiliary reinforcing member 4 is formed in a ring-opening cylindrical shape capable of expanding the diameter, and as shown in FIG. By screwing or press-fitting into the ring-opening cylindrical ridge 4a, the diameter of the ring-opening cylindrical ridge 4a is expanded and pressed against the inner surface of the groove 3a of the main reinforcing member 3. ing. Therefore, the main reinforcing material 3 and the sub reinforcing material 4 are firmly bonded to improve the combined strength, and the bending resistance is substantially the same as when the main reinforcing material 3 and the sub reinforcing material 4 are formed integrally from the beginning. It has strength and bending strength.

  On the side opposite to the ring-opening cylindrical ridge 4a of the sub-reinforcement material 4, a support ridge 4b whose tip is a convex curved surface is formed over the entire length, and the back of the panel is formed by the support ridge 4b. The layer 1b is pressed and supported from the inside. When the support ridge 4b having a convex curved end is formed in this way, the support ridge 4b comes into line contact with the panel back surface layer 1b when the sub-reinforcing material 4 is inserted. The frictional resistance is reduced, and the insertion work is more easily performed. The main reinforcing material 3 is also formed with a plurality of small convex ribs 3d over its entire length. When the main reinforcing material 3 is inserted into the hollow portion 2, these convex ribs 3d are formed on the hollow portion 2. Since the frictional resistance is reduced by making a substantial line contact with the inner surface (in other words, the wall surface of the partition wall), the fitting operation can be performed more easily.

  The reinforcing material-containing hollow panel P having the above-described configuration is assembled in the following manner.

  First, the tenon of the heat insulating cushioning material 5 is fitted into the tenon groove 3b of the main reinforcing member 3, and the heat insulating buffering material 5 is attached to the main reinforcing member 3, and this is inserted into the hollow portion 2 of the hollow panel P. The insertion work of the main reinforcing member 3 is such that the hollow portion 2 is considerably wider than the main reinforcing member 3 and the frictional resistance with the inner surface of the hollow portion 2 is reduced by the convex rib 3d of the main reinforcing member 3. It can be done easily with a margin.

  Next, while inserting and fitting the ring-opened cylindrical ridge 4a of the secondary reinforcing material 4 into the concave 3c of the main reinforcing material 3, the secondary reinforcing material 4 and the main reinforcing material 3 in the hollow portion 2 and the panel are fitted. The main reinforcing material 3 and the auxiliary reinforcing material 4 are inserted into the gap between the back surface layer 1b, the panel surface layer 1a is pressed and supported from the inside by the heat insulating cushioning material 5, and the panel back surface layer 1b is auxiliary strengthened. The supporting protrusion 4b of the material 4 is pressed and supported from the inside. The sub-reinforcing material 4 is inserted and inserted in such a manner that the gap between the main reinforcing material 3 and the panel back surface layer 1b can be slightly increased or decreased by the heat insulating cushioning material 5, and the convex curved surface at the tip of the supporting ridge 4b is the panel. Since it is in line contact with the back surface layer 1b and the frictional resistance is small, it can be easily performed.

  When the operation of fitting the main reinforcing material 3 and the auxiliary reinforcing material 4 into the hollow portion 2 and merging them as described above is finished, finally, the screw or rod is attached to the ring-opening cylindrical ridge 4a of the auxiliary reinforcing material 4. By screwing or press-fitting 6, the diameter of the ring-shaped cylindrical ridge 4 a is expanded and brought into pressure contact with the inner surface of the concave ridge 3 c of the main reinforcing member 3. Are firmly bonded and united. If it does in this way, as already stated, in order to exhibit the bending strength and the flexural strength substantially equivalent to the case where the main reinforcing material 3 and the auxiliary reinforcing material 4 are integrally formed from the beginning, the reinforcement of the hollow panel P is performed. The effect can be greatly improved. In addition, the screw or rod 6 may be screwed or press-fit over the entire length of the ring-shaped cylindrical ridge 4a, or may be screwed or press-fit to both ends in the length direction.

  The hollow panel P containing a reinforcing material assembled with good workability in the above manner has a large bending strength and bending strength of the combined main reinforcing material 3 and auxiliary reinforcing material 4, and exhibits an excellent reinforcing action. The strength of the hollow panel P is greatly improved, and the panel surface layer 1a and the panel back layer 1b are pressed and supported from the inside by the heat insulating cushioning material 5 and the supporting protrusions 4b of the auxiliary reinforcing material 4, so that the hollow portion The main reinforcing material 3 and the auxiliary reinforcing material 4 are not rattled in the inner space 2, and the main reinforcing material 3 and the auxiliary reinforcing material are provided between the panel surface layer 1a and the panel back surface layer 1b by the heat insulating cushioning material 5 described above. Since the heat conduction through the material 4 is cut off and the heat insulation inherent to the hollow panel P is secured, it is possible to prevent condensation on the back surface (indoor side surface) of the hollow panel P even when the outside air temperature decreases. A remarkable effect is obtained.

  As mentioned above, although the synthetic resin hollow panel of the present invention has been described with reference to typical embodiments, the present invention is not limited to this embodiment alone. A concave strip may be formed in the reinforcing material 4. Moreover, it is not always necessary to form the ridges and the ridges over the entire length of the main reinforcing material or the auxiliary reinforcing material, but may be formed in a part of the length direction. Further, both the reinforcing members 3 and 4 are fitted into the hollow portion 2 so that the auxiliary reinforcing material 4 is located on the front surface layer 1a side and the main reinforcing material 3 is located on the back surface layer 1b side. Various modifications such as the main reinforcing material 3 and the auxiliary reinforcing material 4 are inserted and combined in the hollow portions 2 on both side edges of the panel P, or the main reinforcing material 3 and the auxiliary reinforcing material 4 are constituted by a plurality of members. It is acceptable.
