[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer suitable for use in a joint between a square pipe pillar and a bar when a railing of an arch bridge is constructed by passing a bar through a square pipe pillar. .

[0002]

2. Description of the Related Art Bridges over wide rivers or canals in coastal landfills through which ships pass, in order to increase the passage of the ships,
Because it is arched, the balustrade must also be arched along the shape of the bridge. Construction of this balustrade,
As shown in FIG. 5, a pillar 2 made of a square pipe is vertically erected on a bridge 1, a cap 3 is fixed to the top thereof, and a pipe 4 made of pipes is passed in parallel in the middle part. I have.

[0003] However, when the beam 4 is passed through the pillar 2, the beam 4 must be formed in an arch shape.
Must pass diagonally to the pillar 2. But,
In order to pass the bar 4 obliquely to the column 2 in this manner so that no gap is formed around the bar 4,
Holes 5 of different heights along the slope of the hole must be accurately drilled. For this reason, there was a problem that drilling work on the pillar 2 was very difficult. Further, since the inclination of the bridge 1 is different between the center portion and both end portions, there is also a problem that it is necessary to change front and rear drilling positions according to the inclination of the bridge 1.

[0004]

[Problems to be solved by the present invention]
It is intended to provide a washer capable of improving the drilling work on the pillar 2.

[0005]

According to the present invention, a washer is constituted by an inner member and an outer member, both of which protrude the entire inner and outer peripheries of the closed frame plate to one side to form a cylindrical edge. The inner peripheral side edge is formed of a member protruding longer than the outer peripheral side edge, the cross-sectional shapes of the inner peripheral side edges of both members are similar, and the inner peripheral side edge of the inner member has a distal end side of the outer member. The inner diameter is larger than the outer diameter of the inner peripheral edge, and the base side is
It has an inner diameter that closely fits with the outer periphery of the inner peripheral edge of the outer member ,
The inner peripheral edge of the outer member has a length extending from the inner peripheral edge tip of the inner member to the base side.

[0006]

The washer of the present invention is used by engaging the inner peripheral edge of the outer member with the inner peripheral edge of the outer member. At the time of this insertion, the inner peripheral edge of the inner member has a tip side inner diameter larger than the inner peripheral edge outer diameter of the outer member. The peripheral edge can be easily guided to the tip of the inner peripheral edge of the inner member. Also, the base side of the inner member has an inner diameter that closely fits with the inner peripheral edge of the outer member, and the inner peripheral edge of the outer member has a length that extends from the tip of the inner peripheral edge of the inner member to the base side. Therefore, if the two members are pressed together with a force stronger than the frictional resistance due to the close fitting, the two members are engaged with each other and cannot be easily removed.

Since the outer peripheral edges of both members approach each other by the insertion of the outer member, the outer peripheral edges of the two members should be brought into contact with the peripheral wall of the square pipe when the inner peripheral edges of the two members are engaged. For example, the peripheral wall of the square pipe can be present between the outer peripheral edges. Therefore, a hole is made in the square pipe, the inner peripheral edge of the inner member is protruded from the inside of the hole, and then the outer member is inserted, whereby both outer peripheral edges can abut on the peripheral wall.

When the two members are engaged with each other, the two members cover the periphery of the hole for passing the bar formed in the square pipe, so that the gap can be hidden even if the hole is formed larger than the thickness of the bar. . Further, even when both members are engaged with each other, since the rectangular pipe can be moved in the length direction, the inclination of the crosspiece can be adjusted by forming the hole larger than the thickness of the crosspiece. Therefore,
As long as the inner diameter of the inner peripheral edge matches the thickness of the crosspiece,
There is no problem in appearance. The engagement between the two members is performed by placing the inner member in the middle of a square bar longer than the square pipe, inserting the inside member into the square pipe, and then projecting the inner peripheral edge outside the hole of the square pipe to form the square bar. What is necessary is just to fit the inner peripheral side edge of the outer member while supporting both ends of the outer member.

[0009]

1 to 4 show a washer of the present invention.
The inner member 6 is formed by pressing the inner periphery and the outer periphery of a circular ring plate made of a stainless steel plate having a constant entire peripheral width at a right angle to one surface side by press working, so that an inner peripheral edge 7 and an outer peripheral edge 8 are formed.
Are formed, and both edges are cylindrical.
Further, the inner peripheral side edge 7 protrudes longer than the outer peripheral side edge 8, and the front end side expands in a trumpet shape toward the end.

Similarly to the inner member 6, the outer member 9 is formed by pressing the inner and outer circumferences of a circular plate made of stainless steel having a constant overall width to one side at a right angle by pressing to form a projecting length. Are formed on the inner peripheral side edge 7 and the outer peripheral side edge 8 of the inner member 6, respectively, and have a cylindrical inner peripheral side edge 7 a and an outer peripheral side edge 8 a which are substantially equal to each other. Is tightly fitted to the inside of the base side of the inner peripheral side edge 7, and the inner diameter is substantially equal to the thickness of the bar 4 to be installed on the balustrade.

As shown in FIG. 4, this washer is smaller than the outer diameter of the outer peripheral edge 8 of the inner member 6 on the pillar 2 made of a square pipe.
A hole 5 larger than the outer diameter of the inner peripheral edge 7 is made, and the inner peripheral edge 7 of the inner member 6 projects outward from the inside of the hole 5. After the inner member 6 is put on the square bar,
It may be inserted into the column 2, moved to the position of the hole 5, and the square bar may be pressed against the column 2. When the inner peripheral edge 7 of the inner member 6 is projected from the hole 5, the inner peripheral edge 7a of the outer member 9 is aligned with the inner peripheral edge 7 while the square bar is supported, and the outer peripheral edge 8 is
Press firmly until a contacts column 2. Thereby, the outer peripheral side edge 8 a covers the outer peripheral portion of the hole 5. If the column 2 is attached to the bridge 1 in this state and the bar 4 is inserted into the outer member 9, both the inner member 6 and the outer member 9 can move in the length direction of the column 2, so that the bar 4 is adjusted to the inclination of the bridge 1. be able to.

[0012]

As described above, in the washer of the present invention, even when it is necessary to shift the position of the hole to be drilled before and after the column up and down, the position and size of the hole need not be made accurate. Therefore, the work efficiency of column processing can be improved.
