  In the support device 1 of this conventional example, since it is a horizontally long and long shape and the rod-like member 4 is tensioned, there is a disadvantage that when a load from above is applied, distortion in a twisted state occurs. Yes. In this case, since the supporting force against the load cannot be exhibited, the use of the support device 1 is practically impossible.

  Further, when the load is applied to the support device 1 and bent downward, the main body 2 and the rod-like member 4 come into contact with each other. In this case as well, as in the case described above, a sufficient supporting force cannot be exerted with respect to the load from above, so that the support device 1 is practically impossible to use.

  Furthermore, since the side plates 6 and 6 are provided on both sides of the main body 2, there is an advantage that the caterpillar placed on the main body 2 does not fall off from the support device 1. However, since the moving area is limited, it is not possible to cope with an operation of moving the floor surface freely. Therefore, there is also a drawback that the side plates 6 and 6 are disturbed.

  Therefore, in the support device 1 in the conventional example, it is possible to prevent distortion by twisting, to prevent the main body portion 2 and the rod-like member 4 from contacting each other, and to prevent the side plate 6 from getting in the way. And have problems that must be solved.

As a specific means for solving the problems of the conventional example, the present invention is a reinforcing plate member that is installed in a construction and supports a load from above, and the reinforcing plate member includes a floor plate of a predetermined length, A reinforcing portion provided in the vicinity of the central portion; plate-like ribs provided at both ends of the floor plate; a rod-shaped member that passes through the rib and the reinforcing portion; and a nut that is screwed to at least one end portion of the rod-shaped member. And side plates provided on both sides of the floor plate, the nut is tightened to tighten the rod-like member , and the reinforcing portion is a pair of plate portions provided at the lower portion of the floor plate, The present invention provides a reinforcing plate material comprising a bottom plate portion provided at a lower portion of the plate portion .

  And the at least one edge part of the said side plate contains the structure by which the latching | locking part is provided, and also the said side plate contains the structure which stands up predetermined height rather than the said floor board.

A reinforcing plate according to the present invention is a reinforcing plate that is installed in a construction and supports a load from above. The reinforcing plate includes a floor plate having a predetermined length and a reinforcing portion provided near the center of the floor plate. A plate-like rib provided at both ends of the floor plate, a rod-like member that passes through the rib and the reinforcing portion, a nut that is screwed to at least one end of the rod-like member, and both sides of the floor plate The side plate is provided and is configured to tighten the nut to tension the rod-like member , and the reinforcing portion includes a pair of plate portions provided at a lower portion of the floor plate and a bottom plate portion provided at a lower portion of the plate portion. As a result, tension is generated in the reinforcing plate, and the supporting force is reinforced against the load from the upper part.
In this case, by having the reinforcing portion in the vicinity of the center portion of the floor board, it becomes difficult to bend downward when a load is applied from above, and the shape of the floor board is stabilized. Furthermore, unlike the conventional example, the floor board and the bar-shaped member do not contact each other, so that a sufficient supporting force against the load can be exhibited.
And since the supporting force with respect to a load improves compared with the thing of a prior art example, weight reduction is possible as a result.
In particular, the reinforcing portion includes a pair of plate portions provided at the lower portion of the floor plate and a bottom plate portion provided at the lower portion of the plate portion. Sufficient support force with respect to the load can be exhibited without causing distortion as in the example.
Furthermore, since the rod-shaped member is inserted between the plate portion and the rib, the presence of the reinforcing portion makes the rod-shaped member shorter than that of the conventional example, and as a result, the reinforcing plate material can be lengthened. . In addition, there are various excellent effects that the manufacturing cost can be reduced.

  At least one end portion of the side plate is provided with a locking portion, for example, when the building is dismantled, the locking portion is locked to the beam on the floor, and the other end portion is downstairs. When grounded, the working machine can be lowered downstairs over the reinforcing plate material.

  Furthermore, since the side plate stands up to a predetermined height from the floor plate, as described above, when the work machine descends over the reinforcing plate material, the caterpillar of the work machine does not fall off the reinforcing plate material. Has an effect.
