付は部材5i、’5jに取り付けられていた。FIG. 5 shows a conventional undulating gate of this kind, with a door body 5a.
A reinforcing steel pipe 5b is attached to the upper part of the door body 5a, and the copper pipe 5b resists the force acting on the door body 5a, especially the torsional moment. The sheave 5c is housed in a side door stop 5d, and its rotating shaft 5e has one end attached to a support member 5f attached to the side inside the door body 5a.
is supported by Reference numeral 5g is a wire for winding up the door body tied to the sheave 5c, and when the door body a that has fallen on the river bed is to be erected, the wire 5g is wound up by operating a winding device (not shown). However, in the case of this type of gate, since the side end portion of the gate body 5a is supported by the wire 5g, the maximum stress is generated at the side end portion 5h on the wire 5g side, and the side end portion 5h tends to be twisted. was there. Also, it is better to install the sheave 5c at a higher position than the wire 5c.
It is advantageous for the winding operation of the support member 5f, and therefore it is desirable to provide it at a position as high as possible, such as on the side of the steel pipe 5b as shown by the chain line.However, since the steel pipe 5b is a hollow cylinder, the support member 5f is It is difficult to attach the members 51.5 securely to the inside of the steel pipe 5b, and if they are forcibly attached to the inside of the steel pipe 5b,
There is a risk that an excessive load will be applied to the steel pipe 5b and the steel pipe 5b will be extremely twisted or destroyed.For this reason, conventionally, the supporting member 5f of this type of sheave 5c has been placed below the steel pipe 5b as shown in the figure. The attachments fixed inside the door body 5a were attached to members 5i and '5j.

溶接手段などにより固着される。To assemble and construct this type of gate, first install the doorstops 10.10 on both sides of the waterway, pour concrete on the sides 22.22, and then place the doorstops 10.10 between the doorstops 10.10.
will be installed. In that case, the arrangement of the rotating shaft 17 of the sheave 11 becomes a problem. That is, the rotating shaft 17 is disposed at the position indicated by the solid line in FIG. , one end of the rotating shaft '17 protruding from the inner wall surface of the door stop 10 toward the door body 1 becomes an obstacle to installing the door body 1, making it difficult to install the door body 1 between the door stops 10 and 10. . However, in this gate, the door body 1
When installing the rotating shaft 17 as shown by the chain line in Figure 3,
After removing and storing the door body 1 inside the storage body 20 and installing the door body 1 between the doorstops 10 and 10, insert your hand through the opening 19 and slide the rotating shaft 17 to the right in the figure. The attachment hole 231 formed at the end of the cover plate 23 is inserted into the support member 1 in the support column 6.
8.18 should be supported. In this way, when assembling the door body 1, if the rotating shaft 17 is temporarily stored in the storage body 20, the rotating shaft 17 will not become an obstacle for installing the door body 1, and the door Body 1 can be assembled easily. Note that the opening 19 may be closed by a closing member such as a cover plate after the rotating shaft 17 is supported by the support member 18, 18 and the door body 1 is installed. Further, once the rotating shaft 17 is supported by the supporting members 18 and 18, the two are fixed together by welding means or the like.

設置位置を自由に決定できる利点がある。In the above configuration, a large load is applied to the door body 1 especially during a flood or when the door body is rolled up, and therefore a large torsion moment is applied to the door body l and the reinforcing steel pipe 4. Since the hollow support column 6 is fixed and reinforced, it can sufficiently resist the buckling load, and twisting of the door body 1 and the steel pipe 4 can be suppressed to a minimum. Furthermore, since the support column 6 is provided at the side end of the door l, the sheave 11 can be installed at any location. That is, as mentioned above, it is advantageous for the winding operation to install the sheave 11 as high as possible, but in the case of conventional gates, as shown in FIG. Since the steel pipe 5b was attached, it was difficult to install the sheave 5c on the side of the steel pipe 5b, and therefore the sheave 5c was provided on the side of the door body 5a below the steel pipe 5b. However, in the gate according to the present invention, since the support column 6 can be used as a placement part for the support member 18.18, the sheave 11 can be placed at any position on the side of the gate body 1, including the side of the steel pipe 4. can do. Furthermore, even if the sheave 11 must be installed far below the steel pipe 4 due to topographical restrictions at the gate installation site, this can be done without difficulty. In this way, the pillar body 6 is provided at the side end of the door body 1, and the pillar body 6
By utilizing the sheave rotation shaft 17 as an installation part, it not only serves as a reinforcement for the door body l, but also has the advantage that the installation position of the sheave 11 can be determined freely.
