Description

[Technical Field]

[0001] The present invention relates to a fence that is installed around equipment in a factory to ensure the safety of workers. [Background technology]

[0002] Conventionally, in facilities such as factories, a large number of pieces of equipment, such as various types of industrial machinery, are placed, and in order to ensure the safety of workers within the facility, a fence is installed by arranging panels to surround a dangerous area around the equipment and restricting workers from entering the dangerous area. In Patent Document 1, the present applicant discloses a fence that is made up of a panel material and upper, lower, left, and right frames joined together, and includes a frame body that holds the panel material inside the upper, lower, left, and right frames, and magnets provided on the right and left sides of the frame body.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-194062 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] In the configuration shown in Patent Document 1, simply arranging multiple fences close to each other side by side allows them to be connected by the magnetic force of magnets, making it easy to construct a safety fence consisting of multiple connected fences. However, because the fences are temporarily installed in the above-described state, they must be secured to the installation surface. For example, if the fences are secured via leg members attached between adjacent fences, the work on the walkway side is easy, but on the equipment side, workers must go around to the equipment side to attach the leg members between the fences, which is cumbersome. Furthermore, if the leg members on the equipment side are attached together after temporary installation, the temporary fence is prone to tipping over toward the equipment because the leg members on the equipment side are missing during temporary installation. On the other hand, if leg members are attached to the lower horizontal sides of the fence, the number of leg members becomes relatively large, which can make the securing work cumbersome.

[0005] In view of the above, an object of the present invention is to provide a fence that is easy to install. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention is configured as follows: That is, the fence according to the present invention is a fence comprising a plurality of posts erected on an installation surface and panel materials attached between the posts, wherein the posts are provided with mounting members attached to the upper ends of the posts and having mounting portions protruding in the left-right direction, receiving members arranged on the front side of the posts, and pressing members arranged on the front side of the receiving members and clamping the panel materials, the panel materials are attached to the mounting portions via furring strips formed on the upper ends of the panel materials, the mounting members and receiving members are fixed to the front faces of the posts via bolt members, and the posts have female threaded portions into which the bolt members are threaded. Crate , The pressing member has an intermediate portion disposed in front of the head of the bolt member that fixes the receiving member, and a pressing portion disposed rearward of the intermediate portion, and the pressing portion and the receiving member sandwich a portion of the panel material via another bolt member. It is characterized by the following.

[0007] In the fence of the present invention, it is preferable that the mounting member has a storage section that is open downward and stores the upper end of the support post, and that the mounting section is arranged to the side of the storage section.

[0008] In addition, in the fence according to the present invention, the pressing member includes an intermediate portion disposed in front of the head of the bolt member that fixes the receiving member, and a pressing portion disposed rearward and to the side of the intermediate portion, and the pressing portion and the receiving member sandwich a part of the panel material via another bolt member. It is characterized by the following. [Effects of the Invention]

[0009] According to the present invention, when constructing a fence, panel materials can be attached from the front side of the fence, so that when attaching panel materials between the posts, work from the rear side of the fence is not required. [Brief explanation of the drawings]

[0011] Next, a best mode for carrying out the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view showing one embodiment of a fence 100 according to the present invention, and Fig. 2 is a right side view of Fig. 1. The fence 100 according to the present invention comprises a plurality of posts 10 erected on an installation surface, panel materials 20 attached between the posts 10, and mounting members 30, receiving members 40, and holding members 50 for attaching the panel materials 20 to the posts 10. Here, the left-right, up-down, and front-to-rear directions of the fence 100 are the same directions as those shown in Figs. 1 and 2, unless otherwise specified, and the following description will be based on these directions.

[0012] In this embodiment, the support pillar 10 is a steel pipe with a rectangular cross section. Generally, a steel pipe is used because of its stable strength, but other metals may be used instead of steel. Furthermore, the support pillar 10 may be metal-plated or painted to improve its corrosion resistance and weather resistance.

[0013] Figure 3 is a partially enlarged view of the panel material 20 of Figure 1. The panel material 20 is rectangular when viewed from the front, and in this embodiment, vertical members 21 and horizontal members 22 made of steel wire are arranged in a lattice pattern and joined at their intersections to form a mesh.

[0014] Fig. 4 is an enlarged view of the vicinity of the upper part of the support pillar 10 in Fig. 1, Fig. 5 is an enlarged cross-sectional view taken along line AA in Fig. 4, and Fig. 6 is an explanatory diagram of the mounting member 30 in Fig. 3. The mounting member 30 has a front plate portion 31a, a top plate portion 31b, a rear plate portion 31c, and left and right side plate portions 31d, 31d, and is provided with a storage section 31 that opens downward and stores the upper end of the support pillar 10 inside.

[0015] As a result, if the mounting member 30 is placed on top of the support 10 so that the upper end of the support 10 is positioned within the storage section 31, the mounting member 30 can be temporarily fixed to the support 10, as its movement downward, left and right, and forward and backward is restricted by the support 10.

[0016] The front plate 31a of the storage section 31 has a through-hole 31e that penetrates in the front-rear direction. The support 10 has an internal thread 11 at a position that corresponds to the through-hole 31e when the mounting member 30 is placed on it. As a result, after the temporary fastening operation, the front plate 31a can be fixed to the support 10 by screwing a bolt member 61 from the through-hole 31e toward the internal thread 11, thereby fixing the mounting member 30 to the support 10. In other words, the worker can install the mounting member 30 from the front side of the support 10. Note that in FIGS. 4 and 5, a pressing member 50 is arranged on the front side of the mounting member 30; however, as will be described later, the pressing member 50 is installed after the mounting member 30 is fixed to the support 10.

[0017] Next, the relationship between the panel material 20 and the mounting member 30 will be described. Figure 7 is an enlarged end view of line BB in Figure 4, and Figure 8 is a plan view of Figure 4. First, the panel material 20 has furring strips 23 formed on its upper part. In this embodiment, the furring strips 23 are formed by bending the upper ends of the vertical members 21 backward and then folding the tip end side downward, so that they have a U-shaped cross section and are groove-like, opening downward.

[0018] The mounting member 30 has mounting portions 32 that protrude laterally to the left and right from the storage portion 31 and are used to mount the panel material 20. As shown in Fig. 6, the mounting portions 32 are horizontal plate-like portions that extend laterally from the left and right side plate portions 31d of the storage portion 31.

[0019] As a result, by arranging the mounting parts 32 inside the furring strips 23, the downward and front-to-rear movement of the panel material 20 is restricted by the mounting parts 32. Furthermore, as described above, the mounting members 30 can be temporarily fixed to the supports 10, so if the supports 10 are erected at the installation location, the mounting members 30 can be temporarily fixed between the supports 10 without using fixing members such as screws or bolts, and the panel material 20 can be temporarily placed via these mounting members 30, making construction easier.

[0020] Fig. 9 is an enlarged view of the vicinity of the middle of the support pillar 10 in Fig. 1, Fig. 10 is an enlarged cross-sectional view taken along line CC in Fig. 9, and Fig. 11 is an explanatory diagram of the receiving member 40 in Fig. 10. The receiving member 40 is disposed on the front side of the support pillar 10 in the vertical middle.

[0021] As shown in Fig. 11, the receiving member 40 is in the form of a vertical plate, and has a receiving portion 42 that protrudes in the left-right direction from an intermediate portion 41. The intermediate portion 41 has a through-hole 41a that penetrates from the front to the back. Also, as shown in Fig. 10, the support 10 has an internally threaded portion 12 at a position corresponding to the through-hole 41a, and a bolt member 62 can be screwed from the through-hole 41a toward the internally threaded portion 12 to fasten the intermediate portion 41 to the support 10, thereby fixing the receiving member 40 to the support 10. In other words, the worker can fix the receiving member 40 from the front side of the support 10.

[0022] The intermediate portion 41 has step portions 43 formed on both the left and right sides with a step at the rear, and the front side of the support 10 is positioned inside the U-shaped cross section formed by the intermediate portion 41 and the left and right step portions 43, 43.

[0023] As a result, even if the receiving member 40 has only one through-hole 41a, rotation about the bolt member 62 is suppressed.

[0024] 12 is an explanatory diagram of the pressing member 50. The pressing member 50 is in the form of a vertical plate, and has pressing portions 52 that protrude in the left-right direction from an intermediate portion 51. As shown in FIG. 10, the left and right pressing portions 52 are respectively arranged in front of the left and right receiving portions 42 with respect to the receiving member 40. The side edge of the panel material 20 is arranged between the receiving portions 42 and the pressing portions 52.

[0025] The receiving portion 42 has a female thread portion 42a that penetrates from front to back. The pressing portion 52 has a through hole 52a that penetrates from front to back at a position corresponding to the female thread portion 42a.

[0026] This allows a portion of the panel material 20, specifically the vertical members 21 and horizontal members 22 at the side ends of the panel material 20, to be placed in front of the receiving portion 42, and then a holding portion 52 is placed further in front of that, and a bolt member 63 is screwed from the through hole 52a toward the female thread portion 42a, thereby clamping the vertical members 21 and horizontal members 22 of the panel material 20 between the receiving portion 42 and the holding portion 52.

[0027] The pressing member 50 has a shape corresponding to the receiving member 40, and in this embodiment, step portions 53 with a step at the rear are formed on both the left and right sides of the intermediate portion 51, and pressing portions 52 protrude sideways from the left and right step portions 53.

[0028] As a result, head 62a of bolt member 62 that secures receiving member 40 to support column 10 is located behind intermediate portion 51 of retaining member 50, and therefore head 62a is not visible when viewed from the front. Furthermore, head 63a of bolt member 63 that clamps panel material 20 has a relatively small forward protrusion dimension due to step portion 53 of retaining member 50, making it less likely that a passerby will get caught on head 63a.

[0029] Next, an example of a method for installing the fence 100 according to this embodiment will be shown. Figures 13 to 15 are explanatory diagrams showing an example of a method for installing the fence 100. First, the posts 10 are erected at the installation location with a predetermined interval between them, and the mounting members 30 are attached to the upper ends of the posts 10, and the receiving members 40 are fixed to the front sides of the posts 10 at the midpoint in the vertical direction (Figure 13). Note that the mounting members 30 can be temporarily placed on the posts 10, so they may be fixed to the posts 10 at this time, or they may be fixed later.

[0030] Next, the panel material 20 is attached between the posts 10. Specifically, the attachment portion 32 of the attachment member 30 is placed inside the furring strip 23 of the panel material 20, and the panel material 20 is then moved in the direction of the arrow so that it is positioned in front of the receiving portion 42 of the receiving member 40, and temporarily placed between the posts 10 (FIG. 14(a)). This results in the panel material 20 being temporarily placed between adjacent posts 10 (FIG. 14(b)).

[0031] Next, the pressing member 50 is placed in front of the receiving member 40, sandwiching the panel material 20 therebetween (FIG. 15), and the vertical members 21 and horizontal members 22 of the panel material 20 are sandwiched between the pressing member 50 and the receiving member 40 using bolt members 63 (FIG. 2). This fixes the panel material 20 between the supports 10.

[0032] In this embodiment, another pressing member 50 is also disposed on the front side of the mounting member 30 and fixed via bolt members 64. In this embodiment, as shown in Fig. 3, the mounting portion 32 of the mounting member 30 is shaped like a horizontal plate and includes a hanging portion 33 that hangs down from the front side thereof.

[0033] Hanging portion 33 has female thread portion 33a that penetrates in the front-to-rear direction. Pressing member 50 is placed on the front side of panel material 20 that has been temporarily placed on mounting member 30 (FIG. 15), and bolt member 64 is screwed from through hole 52a of pressing member 50 toward female thread portion 33a of hanging portion 33, thereby sandwiching vertical member 21 and horizontal member 22 of panel material 20 between hanging portion 33 and pressing member 52 (FIG. 8).

[0034] As a result, as shown in Figure 8, the head 61a of the bolt member 61 that fixes the mounting member 30 to the support 10 is located behind the middle portion 51 of the holding member 50, so that the head 61a is not visible when viewed from the front, and the head 64a of the bolt member 64 that clamps the vertical member 21 of the panel material 20 has its forward protrusion dimension relatively reduced by the step portion 53 of the holding member 50, so that it is less likely that a passerby will get caught on the head 64a.

[0035] After the fence 100 is installed, if some of the panels 20 are damaged and need to be replaced, or if the panels 20 need to be moved to the rear, a replacement method will be described. First, the retaining member 52 used to secure the panel 20 is removed from the receiving member 40. If a retaining member 50 is secured to the mounting member 30, this retaining member 50 is also removed (the state shown in FIG. 14(b)). At this time, at least one retaining member 50 of the panel 20 adjacent to the panel 20 across the support 10 is also removed, but the panel 20 can remain attached between the support 10. Furthermore, because the mounting member 30 and the receiving member 40 are secured to the support 10 independently of the retaining member 50, removing the retaining member 50 does not affect the secured state of the mounting member 30 or the receiving member 40. Then, the panel 20 can be removed and another panel 20 can be reattached.

[0036] The method of installing fence 100 is not limited to the forms shown in Figures 13 to 15. For example, fence 100 may be formed by erecting a post 10 at a reference position such as a door or corner, erecting another post 10 at a specified interval using this post 10 as a reference, attaching panel material 20 between the posts 10, and repeating this process, that is, by using a so-called one-sided installation method.

[0037] The fence 100 of the present invention comprises a plurality of posts 10 erected on an installation surface and panel materials 20 attached between the posts 10, wherein the posts 10 comprise mounting members 30 attached to the upper ends of the posts 10 and having mounting portions 32 protruding in the left-right direction, a receiving member 40 arranged on the front side of the posts 10, and a pressing member 50 arranged on the front side of the receiving member 40 and clamping the panel material 20 between the receiving member 40, and the panel material 20 is attached to the mounting portions 32 via furring strips 23 formed on the upper ends of the panel material 20, and the mounting members 30 and receiving member 40 are fixed to the front surface of the posts 10 via bolt members 61, 63, and the posts 10 have female threaded portions 11, 12 into which the bolt members 61, 63 thread.

[0038] As a result, when installing the fence 100, if the support 10 is erected on the installation surface, the work of fixing the mounting member 30, receiving member 40 and holding member 50 and the work of installing the panel material 20 can be performed from the front side of the support 10, thereby improving workability.

[0039] In the fence 100 of the present invention, the mounting member 30 has a storage section 31 that is open downward and stores the upper end of the support 10, and it is preferable that the mounting section 32 is arranged on the side of the storage section 31.

[0040] This means that by placing the mounting member 30 on the top of the support 10 so that the top of the support 10 is positioned within the storage section 31 of the mounting member 30, the mounting member 30 can be temporarily fixed to the support 10 without using a fixing member such as a bolt.

[0041] Furthermore, in the fence 100 of the present invention, the pressing member 50 preferably comprises an intermediate portion 51 arranged in front of the head 62a of the bolt member 62 that fixes the receiving member 40, and a pressing portion 52 located rearward and to the side of the intermediate portion 51, and the pressing portion 50 and the receiving member 40 preferably clamp a portion of the panel material 20 via another bolt member 63.

[0042] As a result, the forward protrusion dimension of the head 63a of the bolt member 63 is relatively limited by the step 53 of the pressing member 50, making it less likely that a passerby will get caught on the head 63a. [Explanation of symbols]
