Description

  The present invention relates to a protective fence installed along a boundary of a walking path, a site boundary line, or the like, or along a park, a promenade, a bicycle path, or the like.

  Guard fences installed on the boundaries of pedestrian roads, on site boundaries, and in parks, etc. are generally installed between multiple pillars that are placed at appropriate intervals along the boundaries, etc. It has been constructed and various forms have been proposed. For example, the applicant of the present invention, in a railing where a fence body is installed between struts erected at an appropriate interval, a strut cover is attached to the outer periphery of the strut to cover the support section of the strut and the strut and the fence body. However, the column cover has been proposed as a balustrade formed of a plurality of divided cover materials (see Patent Document 1).

This balustrade has a column cover attached to the outer periphery of the column to cover the column and the column and the attachment part of the fence body, so that it can improve the aesthetics without sacrificing the surrounding scenery, as in the past It is safe because there are no clothes or body hooked by the exposed mounting bolts and nuts of the fence. In addition, since a support cover made of a plurality of divided cover materials is attached to the outer periphery of the support column, it is possible to leave the strength surface as a fence to the support column and to give the support column a free design that takes landscape and aesthetics into consideration. It can be done.

  However, when the entire column is covered with the column in the above-mentioned railing, it is necessary to provide a notch or the like in the column cover so that the lateral beam of the fence body is connected to the column, and the column cover is processed. However, this point was insufficient. Also, if the support cover is covered only on the front and back surfaces of the support and the support is open, the inner periphery of the support cover should be in contact with the outer periphery of the support before and after the support if the support is a prismatic shape. Therefore, the column cover can suppress misalignment and rattling around the column, but if the column is cylindrical, it is difficult to suppress misalignment and rattling around the column. It was lacking.

  The present invention eliminates the above-mentioned problems and provides a protective fence that can suppress the movement of the column cover relative to the column even when the column shape is a column when the column cover is attached to the column. To do.

In order to achieve the above object, the present invention is configured as follows.
That is, the protective fence according to the present invention is a protective fence in which a columnar column is erected at an appropriate interval and a beam is erected via a mounting bracket attached to a side surface of the column. A strut cover wider than the outer diameter of the strut is attached to both the front and rear sides, a strut cap is attached to the upper end of the strut, and a hanging piece is provided at the front and back from the strut cap. It is abutted and the movement of the column cover with respect to the column is suppressed.

  According to the present invention, since the strut cover wider than the outer diameter of the strut is attached to the front and rear surfaces of the strut, the connecting portion between the strut and the beam is covered with the strut cover, thereby improving the design. it can. In addition, a hanging piece is provided at the front and rear from the support cap, and the hanging piece is in contact with the support cover, and the free movement of the support cover with respect to the support column is suppressed. Misalignment can be suppressed.

  In the protective fence according to the present invention, if the hanging piece is made to come into contact with a plurality of locations on both inner peripheral surfaces of the support column cover, the support column cover can suppress displacement in both directions around the support column. it can.

The protective fence P according to FIG. 1 is mainly composed of a support column 1, a beam 2, a support column cover 3, and a support column cap 4, and the connection portion between the support column 1 and the beam 2 is covered by the support column cover 3.

  First, FIG. 1 is a front view showing an embodiment of a protective fence P according to the present invention. The support column 1 is a steel pipe having a circular cross section, and is erected on the ground at an appropriate interval. A support bracket 11 is attached to the side surface of the support column 1, and the end of the beam 2 is attached to the support fixture 11, so that the beam 2 is installed between the support columns 1. In this embodiment, the support column 1 is a steel pipe having a diameter of 60.5 mm and a thickness of 3.2 mm, and the beam member 2 is a steel pipe having a diameter of 48.6 mm and a thickness of 3.2 mm. The treatment has a weather-resistant paint finish. Further, the beam material 2 is mounted in two steps at heights of 500 mm and 780 mm.

  As shown in FIGS. 1 and 2, the mounting bracket 11 has a base portion 12 that is attached to the side surface of the support column 1, a mounting portion 13 that protrudes laterally from the base portion 12, and the mounting portion 13. It consists of pressing parts 14 provided in a pair of upper and lower sides. The end portion of the beam 2 is disposed between the mounting portion 13 and the pressing portion 14 and is sandwiched between the mounting portion 13 and the pressing portion 14. According to the present embodiment, if the base unit 12, the mounting unit 13, and the support column 1 are attached in advance, the beam 2 can be temporarily placed on the mounting unit 13 and workability can be improved. The mounting bracket 11 may be integrally formed, or the beam 2 may be sandwiched from the front-rear direction of the column 1 and is not limited to this embodiment.

  Subsequently, the column cover 3 is a plate-like member made of a synthetic resin as a main component and having a wood-like appearance, and is attached to the front and back of the column 1 as shown in FIG. And, with the column cover 3, the appearance of the round pipe of the column 1 with a metallic feel is made to be a wooden square-like appearance, and the design is enhanced by being attached to the front and back of the column 1 that stands out well in the protective fence P. Is. In the present embodiment, the support cover 3 has a width of about 88 mm and is longer than the outer diameter of the support 1. Thereby, when the guard fence P is viewed from the front, the joint portion between the pillar 1 and the mounting bracket 11 is hidden by the pillar cover 3, so that the design of the guard fence P can be improved. The thickness dimension is about 19 mm. Both strut covers 3 are fixed to the struts 1 with fixing bolts B and nuts N penetrating in the front-rear direction from the center.

  FIG. 4 is an enlarged view of the support cap in FIG. 1, (a) is an enlarged plan view, and (b) is an enlarged front view. The support cap 4 is attached to the upper end portion of the support column 1 to conceal the upper end portion of the support column 1 and the upper end portion of the support column cover 3 attached to the front and back thereof, and an upper surface portion 41 formed in a flat plate shape, As shown in FIGS. 5 to 7, a support portion 42, an insertion piece 43, and a hanging piece 5 formed downward from the upper surface portion 41 are provided.

  First, in the present embodiment, the upper surface portion 41 has a rectangular shape that is vertically long in the front-rear direction with a dimension in the front-rear direction of 104 mm and a dimension in the left-right direction of 93 mm. As shown in FIGS. 5 to 7, the central portion of the upper surface portion 41 is provided with a spherical bulging portion 44 bulging upward. As a result, the design of the upper end portion of the support column 1 is enhanced, and even if rain water hits the upper end portion of the support column 1 during rain, the swollen portion causes the water to flow downward and accumulation of dirt due to the retention of rain water, etc. Can be prevented.

  Next, as shown in FIG. 6, the support portion 42 includes four side walls that are continuous with the peripheral edge of the lower surface of the upper surface portion 41, and the lower surfaces of the front and rear side walls are located above the column cover 3 before and after the column 1. The support cap 4 is placed on the upper end portion of the support 1 through the support cover 3 while being abutted against the end face.

  Next, as shown in FIGS. 5 to 6, the insertion pieces 43 are formed as a pair on the left and right sides from the upper surface portion 41, and are inserted into the pillars 1, respectively. It is in contact with the peripheral surface 15. Then, a screw C is inserted from a through hole (not shown) provided in the upper end portion of the support column 1 and screwed into the insertion piece 43, and the support cap 4 is fixed to the upper end portion of the support column 1. In the present embodiment, a guide groove 46 having a V-shaped cross section extending in the vertical direction is provided at a position where the screw C is screwed in the insertion piece 43. Thereby, the play of the support | pillar cap 4 with respect to the support | pillar 1 in the circumferential direction can be suppressed.

  FIG. 7 is a partial exploded explanatory view for explaining the relationship between the support column 1 and the support column cap 4 in FIG. The hanging piece 5 of the support cap 4 is configured to prevent both end portions of the support cover 3 attached to the front and rear of the support 1 from moving in the front-rear direction, and is formed as a pair of front and rear from the lower surface of the upper surface portion 41. The pair of drooping pieces 5 are configured to come into contact with a facing surface 31 that faces the column 1 in the column cover 3. Thus, the support cover 3 is brought into contact with the hanging piece 5, and the support cover 3 can be arranged in a predetermined horizontal direction with respect to the support 1. Further, in the present embodiment, the respective hanging pieces 5 are arranged at intervals on the left and right sides and are brought into contact with both end portions of the facing surface 31. Thereby, the said play in the both-ends part of the support | pillar cover 3 can be suppressed more effectively, and the backlash and positional deviation of the said both-ends part can be suppressed.

  In consideration of supporting the beam 2, it is preferable to use a metal support column 1. Generally, a long body made of aluminum, stainless steel, steel, cast iron, or the like is cut into an appropriate length. Alternatively, those obtained by plating or painting can be suitably used.

  Considering the required strength of the protective fence P, the transverse beam 2 is preferably made of metal like the support 1 and is generally a long pipe made of aluminum, stainless steel, steel, cast iron, or the like. Those obtained by cutting the body into appropriate lengths, or those obtained by plating or painting them can be suitably used. In the present embodiment, the beam 2 is mounted in two stages up and down, but only one stage or a plurality of stages of three or more may be set as appropriate as necessary. Further, a vertical lattice shape in which a vertical beam is installed between the upper and lower beams 2 may be used.

  In consideration of supporting the beam 2, it is preferable to use a metal fitting for the mounting bracket 11, and in general, a fitting made of aluminum, stainless steel, steel, cast iron, or the like that is plated or painted is suitable. Can be used. In addition, in this embodiment, since the both ends of the beam 2 can be temporarily set | placed on the mounting part 13 by attaching the base part 12 and the mounting part 13 to the support | pillar 1 beforehand, the attachment metal fitting 11 is preferable. It is not limited to this form, for example, it is assumed that the mounting portion 13 and the pressing portion 14 are integrated, and the end of the beam 2 is inserted into this, and the outer peripheral surface of the cylindrical portion A fixing bolt may be screwed inward from the inside, and the beam may be pressed and fixed to the inner peripheral surface of the cylindrical portion, and can be selected as appropriate.

  In general, the column cover 3 is formed by appropriately cutting a long body made of an extruded mold such as synthetic resin or metal into a length. In the present embodiment, a wood powder is blended with a synthetic resin, which can improve designability due to the wood texture, and in addition, is preferable because deformation due to thermal expansion can be suppressed as compared with the synthetic resin alone. The blending ratio of the wood flour is preferably 20 to 150 parts by weight with respect to 100 parts by weight of the synthetic resin material. If it is less than 20 parts by weight, a sufficient wood texture cannot be obtained, and conversely it exceeds 150 parts by weight. And the appearance does not become smooth. Furthermore, the surface of the support cover 3 may be sanded to enhance the wood texture.

  The height positions of the upper ends of the support column 1 and the support column cover 3 are the same height as shown in FIG. 7 but are preferable in appearance, but in this embodiment, the through hole provided in the support column 1 is provided with the fixing bolt B. Since the diameter is larger than the screw diameter, when the column cover 3 is attached before and after the column 1, the column cover 3 may be in a state where the fixing bolt B is attached slightly below the center of the through hole due to gravity. . As described above, when the upper end portion of the support column cover 3 is located slightly below the upper end portion of the support column 1, the support unit of the support column cap 4 can be obtained by attaching the support column cap cover 3 to the height of the upper end of the support column 1. There is a possibility that a gap may be formed between 42 and the upper end surface of the column cover 3. It becomes easy to do. Therefore, the column cap 4 is configured such that the lower surface of the support piece 42 is abutted against the upper end surface of the column cover 3 and the column cap 4 is not in contact with the upper end surface of the column 1 as in this embodiment. Is preferred. At this time, since the lower end surface of the support portion 42 is positioned lower than the upper end surface of the support column 1, the upper end portion of the support column 1 can be concealed by the upper surface portion 41 and the support portion 42 to improve the design. . Further, from the point of matching the height positions of the upper end portions of the front and rear column covers 3 of the column 1, when the column cover 3 is fixed by penetration with the common fixing bolt B as in this embodiment, the front and rear column covers 3 are arranged. In this case, the height position of the upper end portion can be easily matched, which is more preferable.

  The support cap 4 is generally formed by injection molding of a synthetic resin or the like or casting by an aluminum alloy. The embodiment of the support portion 42 is preferable in order to conceal the entire circumference of the upper end portion of the support column 1. However, for example, a form in which side walls are provided only on the front side and the back side of the support column 1 may be used. The form of the insertion piece 43 should just be a form which can be fixed to the support | pillar 1, for example, the some clearance gap may arise between the internal peripheral surfaces of the support | pillar 1. FIG. Further, as shown in FIG. 5, in order to increase the rigidity of the insertion piece 43, a vertical rib 47 extending from the outer surface toward the support portion 42 may be provided. In this case, the height position may be adjusted so that the lower surface of the vertical rib 47 does not come into contact with the upper end surface of the support column 1, or a notch 48 is provided on the lower surface of the vertical rib 47 as in this embodiment. It is good. Note that the vertical rib 47 may be provided between the two insertion pieces 43.

  The hanging piece 5 of the column cap 4 is not particularly limited as long as it suppresses the movement of the column cover 3 with respect to the column 1. For example, the hanging piece 5 may be in contact with both side surfaces or corners of the column cover 3. Alternatively, the support cover 3 may be formed in a hollow shape, and the hanging piece 5 may be inserted into the hollow portion to suppress the play of the support cover 3.

  According to the present invention, when the column cover is attached to the column, even if the column shape is cylindrical, it is possible to suppress the movement of the column cover with respect to the column. Since it is possible to attach a similar column cover, it is possible to improve the design in accordance with the installation environment in addition to the above effects.
