Description

  The present invention relates to a column mounting device for a brace (made of a square tube) used for mounting a device, particularly a signal lamp.

  A pair of clamping frames, each having a groove shape, are fastened to each other by clamping bolts and nuts screwed to the clamping bolts with an arm bracket interposed between them, and the base edge of the straight edge of each clamping frame is brought into contact with the peripheral side surface of the column. In addition, the upper and lower pieces and the base of the band piece interposed between the pieces are connected to each other by a shaft bolt penetrating them and a nut screwed into this, and a support column is wound around the tip side of the band piece. There is a structure in which the bolts are fastened to each other by a tightening bolt and a nut screwed into the bolt (for example, Patent Document 1).

  Since the conventional example adopts a configuration in which the arm metal is mounted by a single band body composed of a plurality of band pieces, there is a possibility that the original column state cannot be maintained by the load applied to the arm metal. In order to cope with this, it is necessary to increase the rigidity of the band body made of steel (plate) by increasing the thickness of the band piece or by widening the band piece. There is.

  The present invention has been devised in view of such a point so as to provide a robust armrest column apparatus having load resistance.

And continuously to horizontally to the left and right ends of the rectangular groove-shaped central piece and the central piece, and in the right and left wing pieces, the pair of upper and lower clamping frame and the same shape to each other isomorphous with each other a pair of upper and lower reinforcing frame A base part of a square tube armature that interposes and engages with the central part piece in a groove shape of the central part piece of the upper and lower holding frames, and an upper holding frame and an upper reinforcing frame that are sequentially superimposed on the upper side Assemble each center piece, and the lower sandwiching frame and the lower reinforcement frame, which are sequentially stacked on the lower side, from the center piece of the upper reinforcement frame to the center piece of the lower reinforcement frame. And tightening each of the left and right wing parts of the upper and lower clamping frames with one clamping bolt and a clamping nut, and tightening the upper and lower clamping frames Between the left and right wing pieces and between the wing pieces and the left and right wing pieces of the upper and lower reinforcing frames Gap formed in each LES, engages one end of each of the band piece pairs of wound posts, the wing piece of the upper reinforcing frame of the lower reinforcing frame toward the wing piece, each one of The other end of each band piece is opposite to the other end of the other band piece through the support column. And a tightening bolt and a tightening nut screwed to the same.

  According to the present invention, since each band piece is fastened to the circumferential surface of the support column by each band piece engaged in the gap defined (configured) by the wing piece such as the holding frame, each band piece is A fixed arm that secures a fixed position without interfering with each other in the vertical direction and is tightened by tightening bolts, and this tightening ensures that the base end edge of the clamping frame etc. is in contact with the side surface of the support column and has load resistance. A metal pillar device can be provided.

The center piece 3a, 3'a is provided with a pair of front and rear through holes 6, 6 for the assembly bolt 5, and the shaft bolt 7 is provided at the base end side of the wing piece 3b, 3'b. A frame body having the same shape and provided with a through hole 8 for use and a through hole 10 for a clamping bolt 9 on the tip side is used symmetrically.

  Further, the upper and lower reinforcing frames 4 and 4 ′ are formed in a horizontal shape at the right and left ends of the square groove-shaped central pieces 4a and 4′a and the central pieces 4a and 4′a, similarly to the holding frames 3 and 3 ′. The left and right wing pieces 4b and 4'b are connected to each other, and the central pieces 4a and 4'a have transparent portions provided in the central pieces 4a and 4'a on the holding frame 3 and 3 'side. A pair of through holes 11 and 11 for the assembly bolt 5 are provided at positions corresponding to the holes 6 and 6, and the wing pieces 4b and 4'b are provided with the through holes 8 on the holding frames 3 and 3 'side. A frame body having the same shape and having the through-holes 12 for the shaft bolts 7 provided at corresponding positions is arranged symmetrically in the vertical direction like the sandwiching frames 3 and 3 '.

  That is, the base piece 3a, 3'a is formed by interposing the base of the arm 1 between the central pieces 3a, 3'a of the upper and lower holding frames 3, 3 'in which the same shape is symmetrically arranged in the vertical direction. The horizontal portion of the central piece 4a of the upper reinforcing frame 4 is arranged above the horizontal portion of the central piece 3a of the upper holding frame 3 and the lower holding frame 3 '. The horizontal portions of the central piece 4′a of the lower reinforcing frame 4 ′ are respectively overlapped with the horizontal portions of the central piece 3′a of the lower reinforcing frame 4 ′ so that the through holes 6 and 11 corresponding to each other coincide with each other. The assembly bolt 5 is passed through the through holes 6 and 11 from the upper reinforcement frame 4 side, and the assembly nut 5A is screwed and tightened to the tip of the assembly bolt 5 protruding from the lower reinforcement frame 4 ', and the upper and lower clamping frames The clamping bolts 9 are passed through the through holes 10 and 10 provided in the 3 and 3 'wing pieces 3b and 3'b so as to coincide with each other and project from the lower clamping frame 3' side. The clamping nut 9A is screwed and tightened to the tip of the bolt 9, and the upper and lower clamping frames 3, 3 'and the reinforcing frames 4, 4' are assembled to the base of the arm metal 1 for use.

  The arm 1 has one end attached to the holding frames 3, 3 'and the reinforcing frames 4, 4' assembled to the base using the wing pieces 3b, 3'b, 4b, 4'b. The band piece 13 is arranged so as to be wound around the peripheral side surface of the column 2, and the other end of the band piece 13 is fastened to the column 2 by tightening each other by the tightening bolt 14 and the tightening nut 14 </ b> A screwed to the tightening bolt 14. Projected and mounted.

  The band piece 13 is formed by press-molding a steel plate, and includes a tightening receiving piece 16 having a through hole 15 at one end and a through hole for the tightening bolt 14 at the other end (known) ), Left and right middle gap portions 16, 16 formed between the upper and lower sandwiching frames 3, 3 ′, and the blades of the upper sandwiching frame 3 and the upper reinforcing frame 4. Formed between the left and right upper gap portions 16 ', 16' and the wing piece 3'b of the lower holding frame 3 'and the wing piece 4'b of the lower reinforcing frame 4' formed between the pieces 4b. Through holes 8, 12 provided on the wing pieces 3 b, 3 ′ b, 4 b, 4 ′ b side by engaging one end of each band piece 13 with each of the lower gap parts 16 ″, 16 ″. And a through hole 15 provided at one end of each band piece 13 are made to coincide with each other, and a shaft nut 7A is threadedly engaged with the end of the bolt 7 protruding from the lower reinforcing frame 4 'through the shaft bolt 7. Frames 3, 3 ′, 4, 4 assembled to the holding frames 3, 3 ′ to the reinforcing frames 4, 4 ′ so as to be rotatable, and assembled to the peripheral side surface of the support column 2 with assembly bolts 5 or shaft bolts 7. Each band piece 13 is wound (contacted) on the peripheral side surface of the support column 2 so as to contact the base end edge (arc-shaped along the peripheral side surface of the support column 2). The tightening bolts 14 are passed from one side to the tightening receiving part pieces 16 and 16 on the other end side of the pair of band pieces 13 and 13 respectively engaged with the gap parts 16, 16 ′ and 16 ″.
