Description

  The present invention relates to a joint washer for a fence, and more particularly to a joint washer for a fence that can reliably close a gap formed between a column and a panel.

  The soundproof blindfold fence that has both the soundproofing effect and the blindfolding effect is a panel made of an iron plate or the like attached between the upper and lower trunk edges 13 as shown in FIG. 7 which is a front view of FIG. 6 and a partially enlarged view of FIG. 12 is fixed between the support posts 11 via a joint 14.

  Conventionally, in the soundproof blindfold fence as described above, the panel end pressing metal fittings 15 are bolted to both the front and back surfaces of the end of the panel 12 in order to reinforce the left and right ends of the panel 12. Hereinafter, the fence panel end holding metal fitting is referred to as a conventional holding metal fitting. As shown in the plan view of FIG. 8, the conventional presser fitting 15 is formed by forming semicircular ribs at both ends in the width direction of a flat plate such as a steel plate.

  According to the above-described conventional presser fitting 15, the end of the panel 12 is reinforced by fixing it to both sides of the end of the panel 12, so that the deformation of the panel 12 can be prevented.

  However, the conventional presser fitting 15 has only a function of reinforcing the panel 12 by sandwiching the end portion of the panel 12, so that it is generated between the column 11 and the left and right end portions of the panel 12 as shown in FIG. 7. The gap (S) could not be closed. The gap (S) cannot be zero because the fence is constructed by fixing the panel 12 between the columns 11. When a gap (S) is generated between the column 11 and the end of the panel 12, there is a problem that soundproofing and blindfolding functions are impaired.

  Therefore, in order to solve the above-described problem, a panel end pressing metal fitting 16 as shown in the perspective view of FIG. 9 has been proposed. Hereinafter, the panel end pressing member 16 is referred to as an improved pressing member.

  The improved presser fitting 16 is formed by bending a flat plate into a planar shape Z shape to form one side piece 16A, a central piece 16B and another side piece 16C. A plurality of elongated bolt holes 17 are formed in the one side piece 16A at intervals in the longitudinal direction of the one side piece 16A. The other side piece 16C abuts on the fence post 11 as shown in FIG. 10 which is a partial perspective view of the fence to which the improved presser fitting is attached, and FIG. 11 which is a cross-sectional view taken along line AA of FIG. Is done.

  According to the improved presser fitting 16, the gap (S) between the support column 11 and the end of the panel 12 can be closed as follows.

  First, as shown in FIGS. 10 and 11, the improved presser fittings 16 are attached to the front and back surfaces of the end portion of the panel 12 by the presser fixture fixing bolts 18. Next, the panel 12 to which the trunk edge 13 and the improved presser fitting 16 are attached is fixed to the column 11 by the joint 14. In this way, when the panel 12 is fixed to the column 11, the presser bracket fixing bolt 18 is loosened and moved to the column 11 side until the other piece 16 </ b> C contacts the column 11. The improved presser fitting 16 can be easily moved to the column 11 side because the bolt hole 17 formed in the one piece 16A is a long hole. Thereafter, the presser foot fixing bolt 18 is finally tightened to fix the improved presser foot 16 to the panel 12. As a result, the gap (S) between the column 11 and the end of the panel 12 is closed.

However, even if the improved presser bracket 16 is used, the gap (S ₀ ) between the column 11 and the end of the panel 12 cannot be closed as shown in FIG. 4 when the fence is viewed from the front side of the fence. It was. The gap (S ₀ ) shown in FIG. 4 is closed by the fence joint washer of the present invention, as will be described later. If the length of the improved presser fitting 16 is equal to the distance between the upper and lower body edges 13, the gap (S ₀ ) is not formed, but a slight gap (S ₀ ) is formed in construction.

When the gap (S ₀ ) is formed, there is a problem that the soundproofing and the blindfold function are impaired as in the case where the gap (S) is formed.

Therefore, an object of the present invention is to provide a joint washer for a fence that functions as a washer for the joint and can reliably close the gap (S ₀ ) between the support column and the end of the panel.

  The present invention has been made to achieve the above object, and is characterized by the following.
