Figure 2 is an exploded perspective view of the pacer of Figure 1;

The present invention relates to an improvement of a stepping device for an elevated temporary platform used for construction of buildings.

When wall surfaces of concrete buildings and the like are sequentially constructed from below to upwards, a construction method for raising the construction stage necessary for assembling the concrete ingots in order to correspond to the concrete building wall surface is currently employed.

The rising temporary stepping device employed in such a method is disclosed in Utility Model Registration Publication No. 20-0355424 filed and maintained by the present applicant.

Conventional apparatus for pacemakers disclosed in the above-mentioned publication is a pacemaker that steps up and down the movable temporary platform along the wall surface of the concrete building on the wall surface.

In the above-described gait device, at the same time the locking projection is fixed to the male bracket fixed to the side end of the temporary table; A locking member externally fixed to a rotatable locking pin on a female bracket fixed to a wall and rotatable in a vertical direction, and a locking member capable of upwardly engaging with a leading end of the locking protrusion, and a leading end of the locking member and hooking of the locking protrusion. Supporting pins for preventing rotation of the locking member downward in a fitted state, respectively; And it is said that the center of gravity is held so that the locking member rotates downward in the non-engaged state.

In such a step device, when the construction table necessary for assembling the concrete wall ingot is sequentially raised corresponding to the construction wall surface, the locking member rotatably mounted to the female bracket fixed to the wall is fixed to the construction table. When the locking projection is fixed to the male bracket and hits the locking projection, the locking member is rotated upward, and when the locking protrusion is positioned above the locking member, the locking projection is downward again by the center of gravity of the locking member. Rotated, the downward rotation of the locking member is prevented by the support pin mounted on the female bracket to support the locking member to the support pin, and at this time, when the hitting projection is lowered by lowering the temporary rod, the locking The member and the locking projection are engaged with each other so that the locking member is supported by the support pin. Is is to be the end, the exchange hypothesis supported by said support pin.

Such a conventional stepping device is currently widely used by allowing the temporary stand to be stably placed on a concrete wall surface in the above manner.

In such a conventional stepping device, the rotatable locking member should be freely rotatable when receiving the temporary placing table, and should be freely rotatable downward by its own weight when the chief's temporary table is descending.

However, in the construction of the building, the construction table is a concrete building wall surface of the upper floor, after the upper floor is built, stepped on each of the two female brackets fixed to the floor of the floor below the floor and then to the floor of the floor below. When the ingot is assembled, foreign matter generated on the floor of the upper floor and cement generated when placing on the ingot of the concrete building wall enter the inside of the female bracket, and the rotatable locking member is in a non-rotable state. Will occur.

When the locking member becomes impossible to rotate, the temporary mounting table becomes impossible to rise, and even if the temporary mounting table is forcibly raised, the locking member cannot be rotated downward by its own weight, so that the worker hammers when the temporary mounting table rises. Alternatively, a situation arises in which the foreign matter or the cement must be removed from the female bracket by an awl or the like.

The present invention is to solve this conventional problem, the cover which can be opened in the upper part of the female bracket to prevent foreign matter or placing cement in the female bracket without impeding the lifting and lowering movement of the locking projection fixed to the male bracket It aims to provide.
