Description

The present invention relates to a fence that is attached along a site boundary such as a store, a factory, a residential area, or an adjacent land boundary, or is installed as a partition in the site.

A wall that is installed along the boundary of a site such as a store, factory, or residential area or the boundary of an adjacent land, or is installed as a partition in the site, is generally a mesh panel in which steel wires are assembled in a grid pattern between columns. , A plate material such as a metal plate or a laminated body in which a metal plate and a resin plate are laminated, and a material to which a panel such as a louver material is attached is used.

When installing these fences, it is often the case that the columns are first buried and cured, and then the panels are attached between the buried columns using connecting members and bolts and nuts. In this case, there are two types of panels, one is a type in which the opposite side can be visually recognized through the panel, such as a mesh panel, and the other is a type in which the opposite side is invisible and blindfolded by an opaque plate material such as a metal plate.

In the present applicant, as shown in Patent Document 1, the fence panel is an external fence composed of columns erected at appropriate intervals and a fence panel attached between the columns. The holding pieces are projected vertically from both side ends toward the support columns, and on the side surfaces of the support columns, a cover piece that hides the back end portion of the fence panel and a receiving piece that is arranged on the back side of the holding piece. A mounting member is provided, and the holding piece is sandwiched between the receiving piece and a holding piece that conceals the front surface of the holding piece.

The base portion 41 is fixed to the side surface portion of the support column 10 via bolts 11 and nuts 12 that penetrate the support column 10 in the left-right direction.

The front fixing portion 42 has an elongated hole 42a penetrating in the front-rear direction, which is the thickness direction. Further, the front panel 20 has elongated holes 20a penetrating in the front-rear direction at the left and right side ends. The nut 44 is screwed into the fixing bolt 43 penetrating the elongated holes 20a and 42a, and the side end portion of the front panel 20 is fixed to the front fixing portion 42. As a result, the front panel 20 is attached between the columns 10.

Next, the mounting structure of the rear panel 30 with respect to the support column 10 will be described in detail. The rear panel 30 is attached to the support column 10 via the attachment member 50.

The mounting member 50 has the same shape as the mounting member 40, and is fixed to the opposite side surfaces of the columns 10 adjacent to each other in the left-right direction. The rear panel 30 is attached via the left and right attachment members 50. The mounting member 50 includes a base portion 51 fixed to the support column 10 and a rear fixing portion 52 formed from the base portion 51 toward the adjacent support column 10 side. In this embodiment, the rear end side of the plate-shaped base portion 51 The rear fixing portion 52 is formed by bending the above, and the cross section is L-shaped. The base portion 51 is fixed to the side surface portion of the support column 10 via bolts 11 and nuts 12 that penetrate the support column 10 in the left-right direction.

The rear fixing portion 52 has an elongated hole 52a penetrating in the front-rear direction, which is the thickness direction. Further, the rear panel 30 has elongated holes 30a penetrating in the front-rear direction at the left and right side ends. The nut 44 is screwed into the fixing bolt 43 penetrating the elongated holes 30a and 52a, and the side end portion of the rear panel 30 is fixed to the rear fixing portion 52. As a result, the rear panel 30 is attached between the columns 10.

In this embodiment, the mounting members 40 and 50 are used by inverting one of them back and forth, and are fixed to the side surface portion of the support column 10 in a state where the base portions 41 and 51 are overlapped in the thickness direction. Although not shown, instead of using two L-shaped mounting members 40 and 50 as in this embodiment, the front and rear ends of the plate-shaped base are bent to form a U-shaped cross section. It may be used as a mounting member.

Next, an example of the procedure for attaching the front panel 20 and the rear panel 30 to the support column 10 will be described with reference to FIGS. 8 to 15. First, the columns 10 are erected on the installation surface at predetermined intervals. Subsequently, the mounting members 40 and 50 are fixed at predetermined height positions of the columns 10.

Next, as shown in FIG. 8, the rear panel 30 is attached to the mounting member 50. First, the rear panel 30 is arranged on the rear side of the rear fixing portion 52, and the fixing bolt 43 is passed from the elongated hole 52a of the rear fixing portion 52 to the elongated hole 30a of the rear panel 30 in the direction of Y1.

15A and 15B are explanatory views of the fixing bolt 43, where FIG. 15A is a front view, FIG. 15B is a side view, FIG. 15C is a plan view, and FIG. 15D is a bottom view. Since the head 45 of the fixing bolt 43 has an elongated shape, the length dimension is shorter than the length dimension of the elongated holes 20a and 52a and longer than the width dimension, and the width dimension is shorter than the width dimension of the elongated hole 52a. As shown in FIGS. 8 to 10, the head 45 can be passed through the elongated hole 52a from the front side of the rear panel 30. This eliminates the need to dispose the fixing bolt 43 on the rear side of the rear panel 30 and pass the screw portion 46 of the fixing bolt 43 from the rear side of the rear panel 30.

As shown in FIG. 15, the fixing bolt 43 has a square root portion 47 and is located between the head portion 45 and the screw portion 46. The corner root portion 47 has a substantially rectangular cross section, and when the fixing bolt 43 is passed through the elongated hole 52a, the corner root portion 47 can pass through the elongated hole 52a in a fitted state in which the rotation of the fixing bolt 43 around the axis is restricted. There is. As shown in FIG. 9, after the head portion 45 and the corner root portion 47 pass through the elongated hole 52a of the rear fixing portion 52 and the elongated hole 30a of the rear panel 30, the fixing bolt 43 is rotated in the R1 direction around the axis. ..

Then, as shown in FIGS. 10 to 11, the length direction of the head 45 intersects the longitudinal direction of the elongated hole 52a, so that the head 45 cannot pass through the elongated hole 30a. After that, the fixing bolt 43 is moved to the front side, and the corner root portion 47 is inserted into the elongated hole 52a to bring it into a fitted state. As a result, even if the fixing bolt 43 is further moved to the front side, the head 45 cannot pass through the elongated hole 52a. Subsequently, by screwing the nut 44 to the screw portion 46 from the front side, the mounting work is completed as shown in FIG.

In this embodiment, two mounting members 50 are mounted on the columns 10 at intervals of the upper and lower sides, and the rear panels 30 are mounted on the adjacent columns 10 via a total of four mounting members 50. The number of mounting members can be appropriately set according to the height dimension of the rear panel 30.

Since the fixing bolt 43 is the same as that used for the mounting work of the rear panel 30, detailed description thereof will be omitted. The head 45 of the fixing bolt 43 can be passed through the elongated holes 20a and 42a from the front side of the front panel 20. Subsequently, the nut 44 is screwed onto the threaded portion 46 of the fixing bolt 43 from the front side to complete the mounting work.

As a result, both the front panel 20 and the rear panel 30 can be attached to the support column 10 from the front side. Moreover, since the front panel 20 and the rear panel 30 are separate bodies and can be made as light as possible, the mounting work becomes easy. Further, if the positions of the front fixing portion 42 and the rear fixing portion 52 in the front-rear direction are adjusted according to the thickness of the front panel and the rear panel, a panel in which the front panel 20 and the rear panel 30 are integrally formed is used. Even without it, the apparent front and rear thicknesses of the front panel 20 and the rear panel 30 and the support column can be matched, so that the support column 10 becomes inconspicuous.

In the present embodiment, the front panel 20 and the rear panel 30 have mounting members 40, 50 fixed to the upper side of the support column 10, that is, the upper and middle stages of the support column 10, via the mounting members 40, 50. , Front panel 20 and rear panel 30 are attached.

As a result, the front panel 20 and the rear panel 30 are located near the height of the eyes of a passerby, the line of sight is blocked, and the blindfold function works.
