Description

  The present invention relates to a crime prevention hollow panel, and more particularly to a crime prevention hollow panel that can prevent human intrusion even when a synthetic resin hollow panel is broken.

  In recent years, translucent hollow panels manufactured by extruding synthetic resin have been used as daylighting walls. This hollow panel is formed by forming a number of hollow parts penetrating in the panel length direction between the panel surface layer and the panel back surface layer. The demand is expected to increase further in the future because it has advantages such as difficulty and ease of handling with light weight and easy handling.

On the other hand, as a lighting window material, roofing material, wall material, etc., by inserting and wiring a heating wire in the hollow part of the resin sheet having a hollow part, functions such as snow melting, anti-fogging, and heat insulation can be exhibited. Has been proposed (Patent Document 1).
Utility Model Registration No. 3029638

  However, the above-mentioned hollow panel used as a lighting wall material has a thin panel surface layer and panel back layer, and can be cut relatively easily with a blade, or softened and melted when heated with a burner or torch. Since it is easy to be destroyed, there is a problem that the hollow panel is intentionally destroyed and a person may enter, and the crime prevention property is inferior. Such a problem is difficult to solve by using a heating wire inserted in the hollow portion of the resin sheet as in Patent Document 1.

  The present invention has been made under the circumstances described above, and the problem to be solved is a crime prevention hollow panel that can prevent intrusion even if a hollow panel made of synthetic resin is destroyed. It is to provide.

In order to solve the above-mentioned problem, the hollow panel for crime prevention according to the present invention has a large number of hollow portions penetrating in the panel length direction between the panel surface layer and the panel back surface layer in the width direction and thickness direction of the panel. A plurality of hollow panels made of synthetic resin, in which some or all of the hollow portions in the intermediate portion in the panel thickness direction are spaced apart from each other so that the intrusion prevention strips prevent human intrusion. And both ends of each strip are fixed to end plates attached to both ends in the length direction of the hollow panel.

  In the crime prevention hollow panel of the present invention, it is desirable that the intrusion prevention strip is a rod, tube, wire, rope, string, tape or chain made of any one of metal, carbon fiber and reinforcing fiber, Of the intrusion prevention strips inserted into some or all of the hollow portions, at least the strips located at both ends are preferably rods or pipes having rigidity made of either metal or carbon fiber.

  And it is desirable that the metal tape is stuck on both ends of the length direction of the hollow panel so as to cover the end plate, and the connecting projection is formed at one end of the hollow panel, and at the other end. It is also desirable that a connecting recess is formed.

Like the crime prevention hollow panel of the present invention, the intrusion prevention strips are spaced apart from each other enough to prevent human invasion, and some or all of the hollow portions at the intermediate portion in the panel thickness direction of the hollow panel. When both ends of each strip are inserted and fixed to the end plates attached to both ends in the length direction of the hollow panel, a sturdy grid is formed by each strip and both ends. Even if the hollow panel is broken by a blade or a burner, it is possible to prevent the intrusion of people by the intrusion prevention strips constituting the lattice body, and to prevent theft and other crimes.

  As the strip material for preventing intrusion, various strip materials having the above strength can be used, but at least the strip material located at both ends is a rod or tube having rigidity made of either metal or carbon fiber. In this case, since a sturdy frame is formed by the strips on both ends and the end plates on both ends of the hollow panel, the strip, which is located in the middle, is one of the metals, carbon fibers, and reinforcing fibers. Using thin and light strips with excellent tensile strength such as wires, ropes, strings, tapes, chains, etc., a lattice body that prevents human intrusion is formed, increasing the weight of the hollow panel and reducing the lighting performance It becomes possible to suppress.

  Also, if a metal tape is attached to both ends of the hollow panel in the length direction so as to cover the end plate, the opening of both ends of the hollow portion of the hollow panel is hermetically closed by this metal tape, and a heat insulating effect is exhibited. Therefore, an indoor warming effect and a dew condensation prevention effect are exhibited.

  And when the connecting ridge is formed on one side end of the hollow panel and the connecting ridge is formed on the other side end, the connecting ridge on one side end is connected to the other side end of the adjacent hollow panel. The hollow panels can be easily connected to each other simply by fitting into the connecting recess.

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

  FIG. 1 is a perspective view showing a hollow panel for crime prevention according to an embodiment of the present invention by disassembling metal tapes at both ends in the length direction, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. FIG. 4 is a partial cross-sectional view showing a connected state of the crime prevention hollow panel.

  This hollow panel 1 for crime prevention is obtained by extruding a lightly colored translucent resin, and, as shown in FIG. 2, a large number of vertical, horizontal, and between the panel surface layer 1a and the panel back layer 1b, A hollow panel having a honeycomb structure provided with slanted partition walls 1c, 1d, and 1e is formed, and by these partition walls 1c, 1d, and 1e, a large number of hollow portions 2 penetrating in the panel length direction are formed on the panel surface layer 1a. And the panel back surface layer 1b. The size of the hollow panel 1 is not particularly limited. In this embodiment, the thickness of the panel (from the panel surface layer 1a to the panel back layer 1b is adjusted so as to be suitable for applications such as daylighting window materials, wall materials, and door materials. The hollow panel 1 is about 40 mm in size, the width of the panel is about 500 mm, and the distance between the vertical partition walls 1 c is about 40 mm. The hollow panel 1 is cut into various lengths corresponding to the construction site. The honeycomb-structured hollow panel 1 in which a large number of vertical, horizontal, and diagonal partition walls 1c, 1d, and 1e are provided between the panel surface layer 1a and the panel back surface layer 1b is practical in spite of its light weight. Although it has a sufficient deflection strength under load and has good daylighting properties, it exhibits a sufficient concealing property in combination with being lightly colored.

  As the material resin for the hollow panel 1, various thermoplastic resins such as polyvinyl chloride, polyacryl, polyolefin, and polyester can be used, and among them, polycarbonate, which is a kind of polyester, is particularly preferably used. This is because polycarbonate has a good balance of strength, moldability, price, and the like, and a high-quality hollow panel can be manufactured at a relatively low cost. Such a polycarbonate hollow panel preferably contains an ultraviolet absorber or a light stabilizer to enhance the weather resistance.

  At one side end of the hollow panel 1, a hollow connecting projection 1 f having a substantially elliptical cross section is formed over the entire length of the panel, and the other side end of the hollow panel 1 is correspondingly formed. In this case, a substantially elliptical ring-shaped connecting groove 1g for fitting the connecting protrusion 1f is formed over the entire length of the panel. Therefore, as shown in FIG. 4, the hollow panel 1 can be simply connected by fitting the connecting protrusion 1 f at one end of the hollow panel 1 to the connecting groove 1 g at the other end of the adjacent hollow panel 1. , 1 can be connected in the width direction.

  In addition, small grooves 1h and 1h are formed on both side ends of the hollow panel 1 over the entire length of the panel. These small grooves 1h and 1h are hollow by using, for example, mounting brackets 101 shown by phantom lines in FIG. When the panel 1 is attached to the trunk edge 102 to construct a wall body, the tip of the mounting bracket 101 is inserted and locked.

  The great feature of the security hollow panel 1 is that a plurality of intrusion prevention strips 3 are inserted into several hollow portions 2 (2a) with a mutual interval sufficient to prevent human intrusion. Both ends of the material 3 are fixed to end plates 4 attached to both ends in the length direction of the hollow panel 1.

  That is, in the crime prevention hollow panel 1 of this embodiment, as shown in FIG. 2, a plurality of (5) intrusion prevention strips 3 made of a high-strength metal (for example, iron) round bar having high rigidity. The horizontal hexagonal shape (lateral) of the middle portion in the panel thickness direction surrounded by the horizontal partition wall 1d and the diagonal partition wall 1e of the hollow panel 1 is set so that the mutual interval is about 80 mm sufficient to prevent human intrusion. The hollow portion 2 (2a) having a dimension of about 40 mm) is inserted one by one, and both ends of each strip 3 are attached to both ends in the length direction of the hollow panel 1 as shown in FIGS. The metal end plate 4 is fixed with screws 5. In this case, a solid metal grid is formed by the strips 3 made of metal round bars and the metal rectangular end plates 4 at both ends, and therefore, it is made of a translucent resin. Even if the hollow panel 1 is destroyed by a blade or a burner, the intrusion prevention strip 3 having an interval of about 80 mm that constitutes the lattice body is surely prevented from entering, and theft and other crimes are prevented. Can do.

  The mutual interval between the intrusion prevention strips 3 is required to be sufficient to prevent human intrusion, so it is necessary to make the maximum interval about 170 mm or less, and above all, the mutual interval is about 100 mm or less. Is preferred. Therefore, in the crime prevention hollow panel 1 of this embodiment, the intrusion prevention strip 3 is inserted into the hollow portion 2 (2a) one by one as described above, and the mutual interval between the strips is set to about 80 mm. However, depending on circumstances, the intrusion prevention strip 3 is inserted into the hollow portion 2 (2a) in three jumps so that the mutual interval is about 160 mm, or is inserted in two to make the mutual interval about 120 mm. Good. Further, the intrusion prevention strip 3 may be inserted through all of the hollow portions 2 (2a) so that the mutual interval is about 40 mm. The overall weight of the hollow panel 1 increases, making it difficult to carry and handle, and the daylighting property is lowered, which is not preferable.

  When the above-described metal round bar is used as the intrusion prevention strip 3, it is preferable to use one having a diameter of about 5 to 20 mm. If a round bar thinner than 5 mm is used, there is a possibility that the round bars will be bent to increase the distance between them, and if a round bar thicker than 20 mm is used, the weight of the crime prevention hollow panel 1 will increase and carry and handle. It becomes painful. The most preferable diameter of the metal round bar is about 10 mm.

  As the strip material 3 for preventing intrusion, a rod (round bar, square bar, etc.), a pipe (round tube, square pipe, etc.), a wire (single wire, stranded wire, etc.) made of any one of metal, carbon fiber and reinforcing fiber, A rope, string, tape, chain, or the like can be used. In the case of a rod or tube, one having a diameter (outer diameter) or length of one side of about 5 to 20 mm, preferably about 10 mm is used. In particular, it is preferable to use a bar or tube having rigidity made of either metal or carbon fiber as the strip located at least on both sides of the strip 3 for preventing intrusion. Since a rigid frame body is formed by the rigid strip material 3 and the end plates 4 at both ends of the hollow panel, the strip material 3 positioned in the middle is any of the above metals, carbon fibers, and reinforcing fibers. Using a thin and light strip material excellent in tensile force such as wires, ropes, strings, tapes, chains, etc., a lattice body that prevents human intrusion is formed, increasing the weight of the entire security hollow panel 1 and lighting There is an advantage that deterioration of the property can be suppressed.

  As shown in FIGS. 1 and 3, a metal tape 6 such as an aluminum tape is attached to both ends of the crime prevention hollow panel 1 in a length direction so as to cover the end plate 4. Since both end openings of the hollow portion 2 of the hollow panel 1 are hermetically closed by the metal tape 6 and a heat insulating effect is exhibited, there is an advantage that an indoor heat retention effect and a dew condensation prevention effect are exhibited.

  In this embodiment, a hollow panel 1 having a honeycomb structure in which vertical, horizontal, and diagonal partition walls 1c, 1d, and 1e are provided between the panel surface layer 1a and the panel back surface layer 1b is used. However, the present invention is not limited to this, for example, a hollow panel in which a number of vertical ribs are provided in parallel between the panel surface layer and the panel back surface layer to form a number of hollow portions penetrating in the panel length direction. Of course, you may use.

  The intrusion prevention strip 3 inserted into the hollow portion 2 is configured to come into contact with the vertical, horizontal, and oblique partition walls 1c, 1d, and 1e, the panel surface layer 1a, the panel back surface layer 1e, and the like surrounding the hollow portion 2. If configured in this way, there is an advantage that it is possible to prevent annoying contact sound that occurs when the hollow panel 1 vibrates in contact with the intrusion prevention strip 3.

  As described above, the crime prevention hollow panel 1 of the present invention has a metal frame attached around it, or a plurality of pieces connected in the width direction and attached with a metal frame around it. It is used for such applications. Even if the hollow panel 1 made of a translucent resin may be broken by a blade or a burner, the intrusion preventing strip 3 inserted into the hollow portion 2 (2a) prevents humans from entering. Because it can be blocked, theft and other crimes can be prevented.

  When the metal frame is mounted around the crime prevention hollow panel 1, the end plates 4 and the metal tape 6 at both ends in the length direction of the hollow panel 1 are omitted, and both ends of the intrusion prevention strip 3 are made of metal. You may comprise so that it may fix directly to a flame | frame.
