Description

  The present invention relates to an anti-sounding strut that prevents the squeaking that may occur in a post of an aluminum extruded material in which a steel reinforcing core material is inserted and disposed in a hollow portion.

  A free strut type fence is one in which a fence body is fixed to one side of a strut of a predetermined interval, e.g., a road, by a bracket or the like, and is attached to a grid fence (also called a mesh fence). In this case, the column is made of a hollow aluminum extruded material with a square cross section or rectangular shape, and after the column is erected, a take-off hook formed integrally with the upper end cap of each column, for example, in the middle of the column in the vertical direction A hook bolt is used to fix the fence body in the middle in the width direction to the support and to connect the fence bodies with a joint.

  In this case, since the column is made of aluminum extruded material with a square cross section or a rectangular hollow one, the appearance is good and the fence body is stable as compared with the steel cross section with a circular shape generally used conventionally. Although the support can be performed, on the other hand, compared to a steel support, the support is inferior in rigidity and the area subjected to wind pressure is increased, so that the support tends to be swung and swung in a strong wind. Therefore, it is possible to insert a steel reinforcing core material from the lower fixed side of the hollow part of the column toward the upper middle part to increase the rigidity of the column and prevent its swinging. When the core material is inserted and the reinforcing core material is fixed with a fixing bracket such as a screw from the bottom of the support column, the reinforcing core material and the support column come into contact with each other near the upper end of the reinforcing core material in a strong wind and the sound of a metal sound is generated. May occur.

  Since this squealing causes a dimensional difference between the inner surface of the hollow portion of the column and the outer surface of the reinforcing core member inserted into the column, the reinforcing core member is fixed by fixing the reinforcing core member at the lower portion of the column. When the gap due to the above dimensional difference is generated on the inner surface of the other side of the column facing the hollow part and the other side of the other side of the hollow unit is opposed to the hollow part, the upper part of the reinforcing core member is not fixed to the column, and thus received strong wind. When it is recognized that the upper part of the column swings somewhat and the column comes into contact with the reinforcing core material. Sound can be effectively prevented.

  However, fixing of the reinforcing core material with the fixing bracket at the bottom of the support column is not conspicuous, but fixing the upper portion of the support column exposes the fixing bracket and impairs the appearance of the support column. Fixing the reinforcing core is not preferable.

  The present invention has been made in view of such circumstances, and the problem to be solved is that the support is made of a hollow extruded aluminum material having a square cross section or a rectangular shape, and a reinforcing core material is inserted to increase its rigidity.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a free strut type grid fence, and the grid fence A is attached to struts 5 at predetermined intervals which are erected on independent or continuous foundations. The fence body 5 is fixedly supported using a hook 51 arranged at the upper end of the support column 1 and a hook bolt 52 in the middle in the vertical direction of the support column 1 according to a conventional method. In addition to supporting the intermediate position in the width direction, the fence bodies 5 are connected to each other adjacent to each other using a joint 53.

  At this time, the support column 1 is for outdoor installation of a hollow aluminum extruded material in which a steel reinforcing core member 2 is inserted into a hollow section having a square or rectangular cross section, in this example, a rectangular cross section. The core member 2 is attracted and fixed to the inner surface of the opposite one of the hollow portions by a fixing bracket from the lower portion of the support column 1, in this example, the screw 3, and protrudes toward the other inner surface of the reinforcing core member 2. The sounding prevention protrusions 26 are disposed in the gap 4 between the reinforcing core member 2 generated by the pulling and fixing and the other inner surface facing the hollow part. As the reinforcing core member 2 is attracted and fixed, the noise prevention projection is formed so as to spot-fill the gap 4 due to the dimensional difference between the support column 1 and the reinforcing core member 2 that is formed on the other inner surface facing the hollow portion. 26 to insert the support column 1 Vertically integrated into the reinforcing core 2, there as to prevent sounding of the post 1 due to swinging possibilities and the swing of the post 1 which occur during high winds.

  In this example, the support column 1 is made of a hollow aluminum material having a rectangular cross section with each side having a width of several centimeters, and is subjected to predetermined processing such as cutting and drilling. In the example, the column 1 has a length (height) of about 1.2 m, excluding a base embedded portion of about 20 cm. At this time, the support column 1 is fitted with a synthetic resin cap 15 at the upper end thereof, and the hollow portion is closed at the upper end, and the fence body 5 is temporarily fixed on the front upper portion near the cap 15. The screw insertion through-hole 11 for fixing the hook 51 is also fixed to the lower part of the front face, in this example, at the upper position in the vicinity of the foundation-embedded portion. While the through-holes 11 are arranged in a transparent manner, similarly, a joint 53 for connecting the fence body 5 is provided at the upper and lower intermediate positions on the front and back sides from above to below so as to penetrate from the front to the back. A plurality of bolt insertion holes 12 to be fixed, a plurality of upper and lower hook bolt insertion holes 13 in this example, and two drainage holes 14 for draining rainwater and dew condensation water in the column 1 are penetrated at predetermined intervals. It is installed and arranged.

  The reinforcing core member 2 fitted into the support column 1 is in this example, and is formed in a C-shaped cross section. The fixing bracket, that is, the drawing and fixing portion by the screw 3 and the noise preventing projection placement portion Is a position in the vicinity of the end portion in the longitudinal direction of each pair of upstanding walls 22 of the reinforcing core member 2. That is, the reinforcing core member 2 is made of steel having a bottom wall 21 and a pair of opposed upstanding walls 22 erected on both ends of the bottom wall 21 with a thick steel plate and having a C-shaped cross section. In this example, a long material having a length of about 80 cm is used, and an end wall is provided at the lower end in the longitudinal direction, and in this example, the wall is erected between the pair of upstanding walls 22 from the bottom wall 21. The arranged end wall 23 having the same width as the upright wall 22 is provided and the lower end is closed. At this time, the reinforcing core material 2 has a bottom wall 21 that is slightly smaller than the width of the side surface of the hollow portion of the support column 1 and a standing wall 22 that is slightly smaller than the width of the front and back surfaces of the hollow portion of the support column 1. In this example, the width of the column 1 is made so that it can be easily inserted into the column 1 by making the width narrower by about 2 mm so as to have a dimensional difference with the inner surface of the hollow part of the column 1. It is formed slightly shorter than the part.

  The bottom wall 21 of the reinforcing core member 2 is formed with a female screw nut 24 at a position corresponding to the screw insertion hole 11 at the bottom of the support column 1. In addition, the through holes 25 are disposed corresponding to the hook bolt insertion holes 13 and the drain holes 14 for fixing the fence main body 5 of the support column 1 and are provided for leveling.

  At this time, the reinforcing core member 2 is further provided with a noise preventing projection 26 on the one standing wall 22 of the opposed pair, and in this example, the noise preventing projection 22 is provided with the reinforcing reinforcement. The core member 2 is an upward or downward inclined protrusion that is inclined toward the direction opposite to the direction in which the core 1 is inserted into the hollow portion of the support column 1, and the noise-preventing protrusion 26 is a part of the reinforcing core member 2. This is due to the cut-and-raised protrusion arranged toward the other inner surface of the column 1 opposite to the hollow portion.

  The sounding prevention protrusion 26 of this example, that is, the inclined protrusion due to the cut-and-raised protrusion is formed on the opposite one-to-one standing wall 22 where the female screw nut 24 is disposed, The standing wall 22 is partially cut and raised in the plane and arranged so as to incline downward. With this, when the noise preventing projection 26 is formed, other projecting members are attached by screws, adhesion, or the like. It can be made integral with the reinforcing core member 2 without being fixed. In this example, the noise preventing projection 26 has a cut-and-raised width of, for example, about 1 cm or less and about 5 to 6 mm, and a cut-and-raised length of about 2 cm or less, for example, about 1.5 cm. Depending on the dimensional difference from the hollow portion of the column 1, for example, this is formed so as to protrude from the opposite standing wall of the other pair by about 2 mm.

  The reinforcing core material 2 is inserted into the hollow portion of the support column 1 to reinforce the support column 1, and the insertion of the reinforcing core material 2 into the hollow portion of the support column 1 is in this example. This is performed so that the lower end, that is, the lower end of the base embedding site, extends beyond the center position in the longitudinal direction of the support column 1 and reaches a range of a little over 1/2 from the lower end of the support column 1 above. It is. At this time, the reinforcing core material 2 is inserted by placing the bottom wall 21 along one side surface of the hollow portion of the column 1 and the opposing pair of upstanding walls 22 along the front and back surfaces of the hollow portion of the column 1 and reinforcing core. The sounding prevention protrusion 26 arranged on the upper part of the material 2 is directed toward the back side of the hollow part of the column 1, and the tip of the sounding prevention protrusion 26 is connected to the hollow part from the lower end of the column 1. This is done so that the sound-preventing protrusion 26 is pressed somewhat elastically by its elasticity, if necessary.

  When the reinforcing core member 2 is inserted, the through holes 25 and the female screw nuts 24 arranged in the bottom wall 21 are connected to the hook bolt insertion holes 13 at the two positions of the support column 1, and rainwater and dew condensation water in the support column 1 are supplied. The insertion is performed so as to match the positions of the drain hole 14 for draining and the thread insertion hole 11 positioned below the drain hole 14. After the insertion, the penetration hole for thread insertion of the support column 1 is performed. The screw 3 is screwed into the nut 24 of the female screw of the reinforcing core member 1 from the hole 11, and the opposing pair of upstanding walls 22 of the reinforcing core member 2 are brought into contact with the hollow portion of the column 1 by pulling the screw 3. The reinforcing core member 2 is pulled and fixed at its lower end with a screw 3 from the front of the support column 1 so as to be pressed against the front side of the hollow portion of the inner surface of the column. Then, the noise prevention protrusion 26 has the dimensional difference, It is interposed in the gap 4 so as to spot-fill the gap 4 formed on the back side of the hollow part of the other inner surface opposite to the hollow part of the support column 1 by the pulling and fixing, and by the lower screw 3 and the upper noise prevention projection 26. By integrating the support column 1 and the reinforcing core member 2, the swinging of the support column 1 and the sound of the metal sound generated when the support column 1 comes into contact with the reinforcing core member 2 are effectively and appropriately generated. Leading to prevention. At this time, even if the remaining portion above the reinforcing core member 2 of the support column 1 is swung, the reinforcing core member 2 does not exist in the remaining portion. The longitudinal direction of the support column 1 that is easily noticeable in the standing construction state, in which the fixing bracket for fixing the reinforcing core material 2, in this example, the screw 3 is only exposed below the support column 1 Screws are not exposed in the middle or above, and the appearance of the column 1 is not impaired.

  Therefore, the column 1 in the grid fence A of this example is a column 1 made of hollow aluminum extruded material by inserting and inserting the reinforcing core material 2 above the column 1 from the foundation embedded portion embedded and standing up on the independent or continuous foundation. However, the rigidity can be maintained at a high level, and the appearance can be improved with the sound generated by inserting the reinforcing core member 2 completely prevented.

  In the figure, reference numeral 27 denotes an opposing pair of reinforcing core members 2 so that the reinforcing core members 2 can be stacked horizontally when the reinforcing core members 2 are stored, transported, and the like, by arranging the noise preventing projections 26. A notch for escaping to receive the noise preventing projection 26, which is disposed at a position corresponding to the longitudinal direction of one of the standing walls 22, is placed on the end wall 23 at the lower end of the reinforcing core member 2 and a pair of opposed standing uprights It is interposed between the walls 22 and is arranged from the lower end of the reinforcing core member 2 to the vicinity of the drain hole 14 of the support column 1, draining rain water and dew condensation water from the drain hole 14 of the support column 1, A waterproofing material made of, for example, an independently foamed foamed synthetic resin material, which is prevented from accumulating and freezing in the winter and damaging the support column 1 is shown.

  Although the illustrated example is as described above, the above-mentioned support is used for other outdoor installations such as a fence other than the grid fence, terraces, balconies, etc. When fixed to the material and formed integrally with the reinforcing core material, instead of the cut and raised protrusions, dot-like protrusions protruding from the standing wall in the form of dots, and the noise prevention protrusions are In the practice of the present invention, including the formation of a plurality of materials in the longitudinal direction or the width direction of the material, the reinforcing core material being a hollow rectangular shape, the fixing bracket being a rivet, etc. Each concrete shape, structure, material, relations, addition to these, etc., such as struts, steel reinforcing cores, fixing brackets, noise-preventing protrusions, inclined protrusions used as necessary, cut-and-raised protrusions, etc. Not contrary to the gist of the invention Ri may be of various forms.
