Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aperture reinforcement device for reinforcing an aperture in a wall made of a thin plate or the like.

When building ships and offshore structures, the entire structure is divided into several blocks and assembled, and the blocks must be reversed during several steps to complete the assembly. It happens all the time.

By the way, although the housing block 1 shown in Fig. 1 has a thin plate structure, it has fewer openings 2 such as door holes for people to enter and exit than the main structure such as the hull. There are so many
When the block 1 is reversed using the wire ropes 3 to 5 in the process shown in Figures A to D, the entire block 1 is bent due to its own weight, which adversely affects the opening 2 and compresses it. The edges become very susceptible to buckling. Furthermore, since a particularly large force is applied to the wall 6 that the reinforcing wire rope 4 comes into contact with during the reversal, sufficient reinforcement is required.

Conventionally, the method of reinforcing the opening 2 as described above has been to attach reinforcing materials such as shaped steel or flat plates by welding. There was a problem in that it required a lot of time and money.

In view of the above points, the present invention provides a reinforcing device for an opening that can be installed and removed extremely easily and in a short time.Examples of the device will be described below with reference to the drawings.

3 to 5, reference numeral 7 denotes a reinforcing device main body made of angle iron along the upper end of the wall 9 having an opening 8, and one side of the reinforcing device main body 7, that is, the angle iron, It constitutes a flat plate part 7a that comes into contact with one wall surface of the body 9, and the other side constitutes the flat plate part 7a.
from the upper end of the wall 9 at right angles to the flat plate portion 7a.
It constitutes a protrusion 7b that protrudes on the opposite side. The reinforcing device main body 7 can be made of two plates assembled by welding into an L-shaped cross section as shown in FIGS. 6A and B, or can be made of channel steel as shown in FIG. It is also possible to assemble three plates into a U-shaped cross section, as shown in the figure below. Reference numeral 10 denotes a holding member that holds the upper end of the wall 9 between it and the flat plate portion 7a, and is attached at two locations in the longitudinal direction of the reinforcing device main body 7. This clamping member 10 includes a clamping member main body 10a made of angle iron fixed to the upper surface of the protruding portion 7b by welding, and a clamping member main body 10a made of angle iron fixed to the upper surface of the protrusion 7b by welding and in contact with the other wall surface of the wall 9. and a contact member 10b made of a flat plate. This clamping member 10 may be provided at three or more locations in the longitudinal direction of the reinforcing device main body 7, and the protruding portion 7
b and the holding member main body 10a may be connected by bolts, nuts, etc. The holding member main body 10a may be assembled by welding two plates into an L-shaped cross section as shown in FIGS. 7A to 7D, or by welding channel steel to the plates as shown in FIG. It may also be something that is firmly attached. Further, if a bolt 11 and a nut 12 are used as the abutment member 10b as shown in FIG. 8, the gap between the flat plate portion 7a and the tip of the bolt 11 can be adjusted as desired depending on the thickness of the wall body 9. Reference numeral 13 denotes a plate body fixed to the reinforcing device main body 7 at a plurality of locations (three locations in this embodiment) in the longitudinal direction by a method such as welding, and the plate body 13 includes:
A plurality of (three in this embodiment) bolt holes 14 are bored along the vertical direction, and the plate 13 located in the longitudinal center of the reinforcing device main body 7 has bolt holes that pass through the openings 8. A hook 15 that engages with the wall 9 is attached by a bolt 16.

When attaching the reinforcing device having the above structure to the wall 9, attach the reinforcing device to the wall so that the upper end of the wall 9 fits between the flat plate portion 7a and the holding member 10 with the hook 15 removed. 9 from the top.
Next, the hook 15 is inserted into the opening 8 as shown in FIG. 5, and is attached to the plate 13 with bolts 16 while being engaged with the wall 9. At this time, as in this embodiment, a plurality of bolt holes 1 are provided in the plate body 13 along the vertical direction.
4, the mounting position of the hook 15 can be adjusted depending on the length from the upper end of the wall body 9 to the opening.

Thus, as shown in FIG. 9, with the reinforcing device attached to the wall 9, the block including the wall 9 is turned over. At this time, since the reinforcing device main body 7 has an L-shaped cross section and has sufficient strength, there is no fear that the periphery of the opening 8 will deform and buckle. Furthermore, since the hook 15 is engaged with the wall 9, there is no fear that the reinforcing device main body will fall off from the upper end of the wall 9 even if the block is reversed.

Next, when removing the reinforcing device from the wall 9,
The bolts 16 are removed, the hooks 15 are removed, and the reinforcing device main body 7 and the clamping member 10 are pulled out from the upper end of the wall body 9.

In this way, the reinforcing device can be attached and detached with extremely easy work and in a short time. Furthermore, the reinforcing device can be reused any number of times, making it extremely economical.

FIG. 10 shows an embodiment in which a wire rope 17 on the auxiliary winding side for reversing the block comes into contact with the wall 9, and 18 indicates plates located at both longitudinal ends of the reinforcing device main body 7. 13 with a pin or the like, and the hook 18 has a
One end of the wire 19 is fixed to a suitable location on the block, and the other end of the wire 19 is hooked. This wire 1
9 is for preventing the wall 9 from falling down due to the force of the wire rope 17. In this case as well, since the reinforcing device main body 7 has sufficient strength, there is no fear that the periphery of the opening 8 will deform and buckle. In this case, in order to protect the wire rope 17 and the reinforcing device, as shown in FIG. You may.

FIG. 12 shows an embodiment in which a plurality of apertures 8 are arranged in parallel in the wall 9, and in this way,
Adjacent reinforcing device main bodies 7 are connected to flat connecting members 21.
They may also be connected to each other by bolts 22 and nuts 23.

As explained above, according to the main body of the aperture reinforcing device according to the present invention, it is possible to attach and detach it extremely easily and in a short time. Moreover, it is economical because it can be reused any number of times, and has a sufficient reinforcing effect due to its high strength.
