The dimension is the sum of the distance between the fence panel 7B and the gap.

In addition, the end post joint unit A and the main post joint unit C can also fix the lower part of the lower fence panel 7B to the lower part of the end post 8A and the main post 8B, respectively, as shown in FIGS. 1 and 2. .

As shown in Figures 1 and 2, the upper fence panel 7A and the lower fence panel 7B are equipped with slit panels 72 made of louvered steel plate, and furring strips 71 made of tubular parts whose upper and lower edges have a cross section formed into a hollow rectangle. In the example shown in Figures 1 and 2, the slit panels 72 are louvered, but other panels, such as those that are punched, may also be used.

As shown in FIGS. 1 and 2, the furring 71 includes rectangular through holes 73 at both ends, each side of which is longer than the diagonal distance of the first nut 53. As a result, the through holes 73 are located at the four corners of the upper fence panel 7A and the lower fence panel 7B, and as shown in FIG. 12, 22, 32 and 42 can abut against the furring 71.

Also, by making the cross-sectional height of the furring strip 71 the same dimension as the height of the panel abutments 12 and 32 as shown in Figure 6, when the fence is constructed, there will be no height difference at the connection between the end post joint fitting 10 and the main post joint fitting 30 and the furring strip 71, resulting in a configuration with excellent aesthetics. In addition, by making the height of the panel abutments 22 and 42 located in the middle of the fence the dimension of twice the cross-sectional height of the furring strip 71 plus the distance of the gap between the upper fence panel 7A and the lower fence panel 7B as shown in Figure 7, there will be no height difference at the connection between the end post middle joint fitting 20 and the main post middle joint fitting 40 and the furring strip 71, resulting in a configuration with excellent aesthetics.

As shown in FIG. 5, the other fastener 60 has the purpose of preventing the second washer 61, the second nut 63, and the second nut 63 from loosening, the outer diameter of which is larger than the diagonal distance of the through hole 73. It consists of a spring washer 62.

Bolt holes 81 for fixing the joint unit are formed in the end pillars 8A and main pillars 8B, which are pillars, at positions corresponding to the heights at which the upper fence panel 7A and the lower fence panel 7B are attached.

According to the components of the present invention having the above features, a fence is constructed as follows.

First, the end post joint unit A, the end post mid-stage joint unit B, the main post joint unit C and the main post mid-stage joint unit D are fixed to the end post 8A and the main post 8B with the post bolt 91 and the post nut 92. At this time, as mentioned above, the post bolt 91 is prevented from rotating by the post bolt holes 13, 23, 33 and 43, so the post nut 92 can be tightened from the back of the fence with only one tool.

Second, the lower fence panel 7B is attached to the joint unit fixed in the first step above. At this time, one of the fasteners 50 fixed to each joint unit is inserted through the through holes 73 located at the four corners of the lower fence panel 7B. Note that since the fixed heights of these joint units are determined in advance, the heights of the through hole 73 and one of the fasteners 50 of each joint unit match. Further, as described above, since the through hole 73 is rectangular with one side longer than the diagonal distance of the first nut 53, the first nut 53 is inserted through the through hole 73, and the first nut 53 is inserted between the rim 71 and each joint fitting. The panel contact portion can be brought into contact with the panel contact portion.

One of the fasteners 50 is pre-fixed to the panel abutment, and the bolt 51 and the first nut 53 protrude on the side that abuts against the lower fence panel 7B. Therefore, as in the second procedure above, when the furring strip 71 and the panel abutment of each joint fitting are in abutment, the edge of the through hole 73 rides up onto the first nut 53, and the lower fence panel 7B is supported by the edge of the through hole 73, so that the position of the lower fence panel 7B can be maintained even if the worker releases his or her hand from the lower fence panel 7B.

Thirdly, the lower fence panel 7B is fixed with the other fastener 60. The second washer 61 and spring washer 62 are inserted in that order onto the bolt 51 protruding from the through hole 73, and the second nut 63 is fastened. At this time, since the bolt 51 is fixed to each joint unit in advance, the bolt 51 is prevented from rotating when the second nut 63 is fastened, even if the worker does not hold it down.

By following the same procedure as above, sequentially attaching another lower fence panel 7B adjacent to the lower fence panel 7B, an upper fence panel 7A, and another upper fence panel 7A adjacent to the upper fence panel 7A between the posts, Fences can be built.

Depending on the situation in which the fence is installed, if there is no need for upper and lower fence panels, the fence may be constructed using only one stage of fence panels. In that case, the end post joint unit A and the main post joint unit C are used to fix the top and bottom of the fence panel, and the end post middle joint unit B and the main post middle joint unit D are not used. Furthermore, when installing a fence with a high overall height, the fence panels may be stacked in three or more tiers. In that case, it is possible to cope with this by increasing the number of end column intermediate joint units B and main column intermediate joint units D.

According to the fence of the present invention constructed with the above-mentioned features, when fixing the fence panel, there is no need to insert the bolts 51 or stop them from rotating from the front of the fence. You can build a fence with only a few tasks. Furthermore, since the fence panel can be temporarily placed on one of the fasteners 50 fixed to the joint unit, the work efficiency is good when fixing the fence panel with the other fastener 60, and only one worker can do it. You can even build a fence.

Further, according to the present invention, since one of the fasteners also has the function of temporarily placing the fence panel, there is no need to provide a joint fitting or the like with a shape intended for temporarily placing the fence panel. Therefore, compared to the joints used in conventional fences, the joints of the present invention can have a simpler structure, making it possible to reduce the weight and reducing the workload.

In addition, although the case where one fastener 50 is comprised of the bolt 51, the first washer 52, and the first nut 53 has been described above, the one fastener is not limited to this, and can be used to connect a bolt to a joint. It may be fixed by direct welding to the panel abutment part of the metal fitting. Alternatively, a nut may be welded to the panel contact portion of the joint fitting as one fastener, and a bolt may be fastened as the other fastener from the back side of the fence. Moreover, although the case where the support column is a round pipe with a hollow circular cross section has been described above, the shape of the support column is not limited to this, and a square pipe, H steel, or the like may be used. It is clear from the claims that such modifications or improvements may be included within the technical scope of the present invention.
