  In addition to the above, the invention described in claim 7 can be configured so that the horizontal frame is a horizontal frame of the partition surface body, and the partition surface body can be connected and supported to the support column.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a handrail as a ground installation installed on a staircase, and the handrail A is installed upright at predetermined intervals, for example, a column 1 having a circular section. In addition, a partition surface 2 formed by processing and assembling an aluminum extruded material is connected and supported between adjacent struts 1, and the partition surface 2 has a horizontal frame 21 arranged vertically and the upper and lower horizontal frames 21. A number of vertical bars 22 are formed as partitioning surfaces arranged between them. At this time, the upper and lower ends of the vertical bars 22 are fixed to the upper and lower horizontal frames so as to be freely rotatable, thereby being horizontally and inclined. In any case of installation, the vertical beam 22 is always vertical.

  The partition surface body 2 is connected to the upper and lower horizontal frames 21 adjacent to each other so that the column 1 is sandwiched between the column bracket 3 and the frame frame joint 4. In this example, a long hole 35 is formed so as to project a T-shape such as a flat L-shape, a T-shape, or a U-shape. The horizontal frame joint 4 has an attachment leg 41 for attaching the end of the horizontal frame 21, and protrudes from the attachment leg 41 in the extending direction of the horizontal frame 21 through the bolt insertion hole 43. It is assumed that a connecting projection piece 42 is provided, and for connection using these, the column bracket 3 is attached to the column 1 at a predetermined position on the side surface of the column 1 through the long hole 32 of the mounting substrate 31. Fixed, the long hole 35 of the connecting protrusion 34 and the horizontal frame joy Horizontal frame 21 by through a bolt insertion hole 43 of the connecting protrusion 42 of the bets 4 securing fastening these connecting protrusion 34, 42 by bolts nuts 5 are carried across the post 1.

  The support bracket 3 has a mounting substrate 31 which is a curved substrate in accordance with the side surface of the support column 1 having a circular cross section, a connecting projecting piece 34 as a single projecting piece, and a long hole 32 of the connecting projecting piece 34. The long holes of the connecting protrusions 34 are curved holes arranged so as to be curved along the arc, and the horizontal frame joint 4 has the connecting protrusions 42 as a pair of parallel protrusions. 3 is fixed in a state where the connection protrusions 34 and 42 are sandwiched, that is, a single connection protrusion 34 of the column bracket 3 is sandwiched by a pair of parallel connection protrusions 42 of the horizontal frame joint 4. It is assumed that this was done.

  At this time, the support column 1 and each horizontal horizontal frame 21 sandwiching the support column 1 have a horizontal line connecting the intersection point P of the axis of the support column 1 as a virtual base and an inclination line connecting the horizontal frame having the maximum inclination angle and the intersection point P. Assuming virtual right triangles as virtual hypotenuses, a vertical height difference L1 of a virtual vertical side that changes according to the position of the bolt insertion hole 43 of the virtual right triangle due to the elongated hole 32 of the mounting board 31 in the support bracket 3 is set. The bolt insertion hole 43 of the horizontal frame joint 4 can be separated from and connected to the column 1 by the long hole 35 of the connecting protrusion 34 in the column bracket 3 and the maximum inclination angle from the horizontal position of the horizontal frame 21 can be obtained. The horizontal length difference L2 of the hypotenuse that changes according to the position of the bolt insertion hole 43 of the hypothetical right triangle is made to be freely absorbable. The horizontal frame 21 is arranged so that the intersection P between the horizontal frame 21 and the axis of the column 1 is always set to the same fixed point, and the horizontal and inclined connections in the longitudinal direction of the horizontal frame 21 with respect to the column 1 Both the support and the connection support in the plane bending direction are possible, and it can be used on both the flat ground and the inclined ground such as stairs and slopes, and further, the step of the upper and lower horizontal frame 21 sandwiching the support pillar including the position of the support pillar 1 whose plane angle changes It has been resolved.

  In other words, in this example, the column bracket 3 has the elongated hole 32 of the mounting substrate 31 as the curved substrate, and the vertical height difference L1 of the virtual vertical side above and below the intersection P as the upper and lower center positions. It is assumed that it has a length and is vertically pierced, and that the connecting projection 34 protrudes from the mounting substrate 31 in a semicircular shape displaced upward and downward, and the upper and lower ones of the displaced connecting projection 34. A long hole 35 that is a curved long hole is formed through the curved long hole. At this time, the curved long hole has an angle of, for example, 40 degrees from a horizontal position along an arc centered at an arbitrary point of the connecting protrusion 34. It is assumed that they are arranged in a manner.

  The column bracket 3 can be placed upside down with the column 1 interposed therebetween so that the curved elongated holes can be arranged symmetrically with respect to the intersection point P at the top and bottom of the column and the intersection point P can be positioned at the vertical center position. It is possible to adjust the position by moving the mounting position up and down by 1/2 of the length of the long hole 32 in a vertically inverted state by the vertical long hole 32 of the mounting substrate 31. By arranging this, the axis of the horizontal frame 21 through which the long hole 32 of the mounting substrate 31 passes through the intersection P or the parallel lines above and below the virtual hypotenuse of the virtual right triangle are generated. By absorbing and attaching the vertical height difference L1 of the vertical side, the horizontal frame 21 connected with the support column 1 forms a series of straight lines, and the angle changes at the intersection point P with the support column 1 interposed. Theft is possible. At this time, since the axis of the horizontal frame 21 or the parallel lines above and below the intersection P pass, the position of the bolt insertion hole 43 of the horizontal frame 21, that is, the horizontal frame joint 4 attached to the end of the horizontal frame 21 becomes the curved elongated hole 35. As a result, the lateral frame 21, that is, the bolt insertion hole 43 is allowed to move away from the support column 1, and the curved long hole 35 is moved away from the bolt insertion hole 43. As a result of absorbing the moving distance of the fastening position, that is, the horizontal length difference L2 of the hypothetical hypotenuse of the virtual right triangle, the horizontal frame 21 sandwiching the column 1 can simultaneously change the angle at a series of straight lines or intersections P. As a result, the horizontal frame 21 sandwiching the column 1 is connected and supported in a state without a step. The curved long hole 35 can be attached to an arc centered on the intersection point P. However, the rotation of the bolt insertion hole 43 in the curved long hole 35 need not be centered on the intersection point P. Therefore, in this example, the curved long hole 35 follows a circular arc having a relatively small radius centered on an arbitrary point of the connecting projection piece 34.

  In this example, the bolt insertion hole 43 in the horizontal frame joint 4 is made transparent at a position moved slightly downward from the axis of the horizontal frame 21, so that the straight line of the horizontal frame 21 passing through the intersection P is Although the bolt insertion hole 43 is positioned on the axis of the horizontal frame 21, the relationship between the intersection point P and the horizontal frame 21 does not change even if the bolt insertion hole 43 is positioned on the axis of the horizontal frame 21.

  The procedure of installing the partition surface body 2 by connecting the horizontal frame 21 to the support column 1 is, for example, standing the support column 1 at a predetermined interval, and connecting the support column 1 to the support column 1 through the long hole 32 at the intersection P height, for example. The column bracket 3 in which one of the two screws 33 is screwed and temporarily fixed, and the horizontal frame joint 4 in which the mounting leg 41 is fitted into the hollow portion of the horizontal frame 21 and temporarily fixed with the screw 44 in the same manner. Are temporarily fastened with bolts and nuts 5 for fastening them, and the horizontal frame 21, in this example, the upper and lower horizontal frames 21 of the partition surface 2 is temporarily supported between the columns 1, and then the partition Hold the face piece 2 in accordance with the inclination angle of the staircase or slope, swing it up and down or left and right, the axis or parallel line of the horizontal frame 21 passes through the intersection point P, and the bolt nut 5 is positioned. And tighten the screws 33 and 44 and bolts and nuts 5 Serial and the other screw 33 of the two may be fixed to the strut bracket 3 which position has been determined by screwed to the post 1 through the elongated hole 32. At this time, the partition surface body 2 at a position where the plane angle changes is attached to the projecting corner or the entering corner if the column bracket 3 is attached to the column 1 at a position determined according to the angle in the outer circumferential direction. This can be done by bending at an appropriate angle, including the formation of a right corner.

  In the figure, reference numeral 6 denotes an intermediate lateral installed so as to extend to the lower flat ground side of the handrail A at an intermediate height position of the partition plane 2 inside the handrail A at an angle that follows the angle of the horizontal frame 21 of the handrail A. A frame 62 is a bracket in which the intermediate horizontal frame 6 is fixed and held in a take-out shape by being fixed to a dedicated column 61 standing on the extended end of the column 1 to the horizontal frame 6 of the handrail A.

  Although the illustrated example is as described above, the elongated holes of the connecting protrusions in the column bracket need only be configured so that the horizontal frame 21 can be separated from and connected to the column bracket. In addition, when the elongated hole is a curved elongated hole, the angle thereof is, for example, ¼ circle with the intersection point as the central horizontal line. By expanding the angle, it is possible to connect the horizontal frame in the same way by attaching the column bracket to the column without flipping it up and down, and superimposing the coupling protrusions in the above clamping state In some cases, the connecting projections of the column brackets can be a pair of parallel projecting pieces, and the connecting projections of the horizontal frame joint can be a single projecting piece. In carrying out the present invention including these, ground installations, support posts, support brackets, their mounting boards, their long holes, connecting protrusions, their long holes, horizontal frame joints, their mounting legs, connecting protrusions, Each specific shape, structure, material, relationship between these, the addition to these, etc., such as the bolt insertion hole, can be in various forms as long as they do not contradict the gist of the invention.
