Next, the construction method of the flip-up type gate 1 of this embodiment is demonstrated.
First, a pair of short arms are prepared to construct a flip-up gate.
In FIG. 7, the short arm 10 constitutes the portal-type positioning jig 100 shown in FIG. 9 together with the tip connecting member 6 and the connecting rod 9.
The short arm 10 is engaged with the engaging portion 31 of the bracket 3 and the tip connecting member 6 instead of the main arm 4 shown in FIG. 3, and is a rectangular tube-shaped member having the same cross-sectional shape as the main arm 4. It is. At both ends of the connecting rod 9, two bolt holes 4 </ b> A through which the bolts B are inserted at the same positions as the both ends of the main arm 4 are formed. The distance between the centers of these bolt holes 4A is L1, and the position between the end edge of the short arm 10 and the center of the bolt hole 4A closest to this end edge is L2.
One end of the short arm 10 is a fitting concave portion 11 as an engaged portion into which the fitting convex portion 310 of the engaging portion 31 is inserted and fitted. The other end of the short arm 10 is a concave portion 12 into which the convex portion 61 of the tip connecting member 6 is inserted and fitted.

The length of the short arm 10 may be shorter than that of the main arm 4, but specific values thereof include the height of the connecting rod 9 after the positioning jig 100 is installed on the gate pole 2, and the short arm 10 is a bracket. 3 is set concretely in consideration of the dimension that enables engagement with 3.
That is, the short arm 10 has a lower limit value for the insertion length of the fitting convex portion 310 of the engaging portion 31 and the convex portion 61 of the tip connecting member 6 without interfering with each other. For example, since the protrusion dimension L of the fitting convex part 310 and the protrusion dimension L of the convex part 61 are both 60 mm, the lower limit of the length of the short arm 10 is 120 mm.

On the other hand, in a state where the main arm 4 and the sub arm 5 are not attached to the bracket 3, the tip of the fitting convex portion 310 faces upward. Since the short arm 10 is attached to the fitting convex portion 310 with one end facing upward, the other end of the short arm 10 is the upper end.
In the present embodiment, as will be described later, a level (not shown) is installed on the connecting rod 9 connected to the other ends of the pair of short arms 10, and the level may be read from the level. From the standpoint of installation workability and reading workability, it is necessary to consider the height of the person installing the gate. For example, if the height at which the person installing the gate is easy to work (the height of the shoulder of the worker) is 1400 mm, the upper end position of the gate pillar 2 is about 1200 mm, and this position is the lower end position of the short arm 10. If it exists, the upper limit of the length of the short arm 10 will be 200 mm or less. The lower limit value and the upper limit value of the length of the short arm 10 are not limited to these numerical values.

Next, the short arm 10 having the above configuration and the members constituting the flip-up gate 1 are packed together.
At the time of packing, as shown in FIG. 8, the main arm 4 and the tip connecting member 6 may be attached in advance with the bolt B, or the connecting rod 9 and the tip connecting member 6 are attached in advance with the bolt B. (See imaginary line).
Each member constituting the short arm 10 and the flip-up gate 1 is transported to the installation site as one package.

As shown in FIG. 9, when constructing the flip-up type gate 1, first, a pair of gate pillars 2 is temporarily installed. The bracket 3 is attached prior to or after the installation of these gate pillars 2.
[Positioning jig assembly process]
When the tip connecting member 6 is attached to the tip of the main arm 4 with a bolt B in advance, the tip connecting member 6 is removed from the main arm 4, and the convex portion 61 of the removed tip connecting member 6 is replaced with the short arm 10. And inserted into the concave portion 12. When the tip connecting member 6 is attached to the connecting rod 9 with a bolt B in advance, the convex portion 61 of the tip connecting member 6 is inserted into the concave portion 12 of the short arm 10 and fitted.
A portal-type positioning jig 100 is assembled by the pair of short arms 10, the tip connecting member 6 and the connecting rod 9. The angle formed by the short arm 10 and the connecting rod 9 is a right angle.

[Positioning process]
The positioning jig 100 is held above the bracket 3, and then the fitting protrusions of the bracket 3 provided on the pair of left and right portal posts 2 in the fitting recesses 11 of the pair of short arms 10 constituting the positioning jig 100. The positioning jig 100 is slowly lowered so that 310 is inserted. If the short arm 10 cannot be inserted into the fitting convex portion 310 of the bracket 3, the relative position of the pair of left and right portal columns 2 is incorrect. Direction), Y direction (front-rear direction), and Z direction (vertical direction).
For example, one of the pair of left and right gate pillars 2 is used as a reference gate pillar 2, and the other gate pillar 2 is positioned in the X direction, the Y direction, and the Z direction.

In a state where the positioning jig 100 is accurately attached to the gate pillar 2, the distance between the left and right gate pillars 2 is the distance between the finished gate pillars 2, and the parallel inner surfaces 2 </ b> A of the pair of gate pillars 2 are secured.
Furthermore, in this embodiment, a level (not shown) is disposed on the connecting rod 9 and the inclination of the gate pillar 2 with respect to the YZ plane is observed. When the entire pair of gate pillars 2 is tilted in the YZ plane, the pair of gate pillars 2 is tilted as a whole so as to correct this tilt. Further, a beard (not shown) is installed on the gate pillar 2 and the inclination of the entire pair of gate pillars 2 with respect to the XZ plane is observed. If the pair of gate pillars 2 is inclined with respect to the XZ plane as a whole, the pair of gate pillars 2 is inclined as a whole so as to correct this inclination.

[Gatepost installation process]
The pair of positioned gate columns 2 are fixed by placing concrete at a predetermined position.
In this gate pole installation process, the gate-shaped positioning jig 100 is left attached to the pair of gate poles 2.
[Positioning jig disassembly process]
When the gate pillar 2 is fixed, the positioning jig 100 is removed from the brackets 3 provided on the pair of gate pillars 2 respectively. Therefore, when the positioning jig 100 is lifted with respect to the bracket 3, the fitting concave portion 11 of the short arm 10 is pulled out from the fitting convex portion 310 of the bracket 3. Further, the short arm 10 of the positioning jig 100 is extracted from the tip connecting member 6.

[Gate completion process]
The convex portions 61 of the distal end connecting members 6 provided at both ends of the connecting rod 9 are respectively fitted into the concave portions 42 on the distal end side of the pair of main arms 4, and the pair of engaging portions 31 of the pair of brackets 3 are paired with the pair of engaging portions 31. The base ends of the main arms 4 are respectively fitted.
Further, an engagement member 322 is attached to an engagement pin 321 provided on the protrusion 32 of the bracket 3, and the base end portion of the sub arm 5 is engaged with the engagement member 322. A tip connecting member 7 is attached to the tip of the sub arm 5.
The door body 8 is attached to each of the tip connecting member 6 attached to the tip of the main arm 4 and the tip connecting member 7 attached to the tip of the sub arm 5 to complete the flip-up gate 1.
When the construction of the flip-up gate 1 is completed, the short arm 10 is taken back from the gate installation site to the storage location.

Therefore, in the present embodiment, the following operational effects can be achieved.
(1) A pair of short arms 10 shorter than the main arm 4 are prepared, and the ends of these short arms 10 are connected by connecting rods 9 to assemble a gate-shaped positioning jig 100. The left and right front and rear and the top and bottom of the pair of gate pillars 2 are engaged so that the fitting recess 11 provided on one end side of the short arm 10 is engaged with the engaging portion 31 of the bracket 3 rotatably provided on the gate pillar 2. Determine relative position. Thereafter, the pair of positioned gate pillars 2 are fixed, the short arm 10 of the positioning jig 100 is removed from the bracket 3, the connecting rod 9 is removed from the short arm 10, and the positioning jig 100 is disassembled. The fitting recess 41 is engaged with the engaging portion 31 to attach the main arm 4 to the bracket 3, the distal end side of the main arm 4 is coupled by the coupling rod 9, and the door body is disposed on the distal end side of the main arm 4. Install 8 to complete the gate. In the present embodiment, a pair of gate pillars 2 is positioned by using a gate-type positioning jig 100 configured by attaching a connecting rod 9 between the other ends of the pair of short arms 10. 2 positioning, in particular, the size between the pair of gate pillars 2 can be easily adjusted to a specified value.
