Description

  The present invention relates to a work scaffold device and a work scaffold for indoor construction.

  In the technical field of work scaffolding, for outdoor construction, the invention according to Patent No. 3148886 was developed and patented by one company of the present invention. As the invention for indoor construction, the following is well known as a structure that can be folded.

Japanese Patent No. 2899751 Japanese Patent No. 3909522 Japanese Patent No. 2990376 Utility Model Registration No. 2528462 Registered Utility Model No. 3035144 Registered Utility Model No. 3035632 Publication

  However, since these scaffolding plates consist exclusively of two folding means that turn from an open horizontal state during use to a closed vertical state when not in use, the total length stands upright to a height of nearly 2 m, When not in use, it will be moved to a warehouse or factory wall via a moving wheel, and will be moved to a predetermined place when necessary. When trying to move the body, there was a drawback that the traveling direction could not be confirmed well, and there was a disadvantage that it took time to assemble.

  Accordingly, an object of the present invention is to provide a rational and highly workable indoor work scaffold that eliminates these drawbacks.

  In the present invention, the upper end portion of the central member is constructed by connecting two work base plates that are scaffold members that expand in both the left and right directions, and the work base plates can be folded in the vertical and vertical directions. It is a scaffold device that sets the height below the operator's line of sight.

  In the present invention, center members having pipes on both left and right side portions are installed on both front and rear side portions at an appropriate interval. The lower ends of both central members thus configured are installed at the central part of the abutment having moving wheels on both the left and right sides, and each work table that serves as a scaffolding member in the left and right sides above the central member. The plates are connected to a part of the frame so that the upper ends of the right and left pipes of the central member can be pivoted and folded in the vertical direction. It is a scaffolding that can be folded in

  The working platform of the present invention is such that the working platform plates that serve as scaffolding members can be connected in series in the left and right sides of the central member and can be folded vertically in the vertical direction. Even if a two-link scaffolding member with a large area is configured, it can be moved in a folded state below the height of a normal worker, and many of these can be moved. Even if you keep it upright when you are not using it, you will be able to see through the hall sufficiently and will not hinder the work.

  In addition, the connection and folding structure of each scaffold member is relatively simple and sufficiently considers safety.

Bottom perspective view showing the relevant state before the main part is assembled Bottom perspective view just before the main part is assembled Bottom perspective view before assembling essential parts Front perspective view of main parts after assembly Plan view of main parts Full perspective view during folding when not in use Full perspective view after folding when not in use

  In a state of being gathered at a predetermined place when not in use, the work platform of the present invention is a vertically upright vertical work platform plate in which the scaffold members installed on the left and right sides of the central member are respectively connected to each other. In this state, as shown in FIG. 10, the lock pins are connected to the left and right work platform plates to be connected at the top between the frame members of the adjacent work platform plates. Lock pins are latched between the frame members of the work base plate at the front and rear portions of the intermediate portion between the frame members.

  Therefore, when this is used, the device in the folded vertical state as shown in FIG. 10 is left and moved to the indoor work place in a predetermined building, and the moving wheel stoppers are moved on the spot. After removing the lock pin, a plurality of work platform plates connected to the scaffold members installed on the left and right sides of the central member are deployed in a horizontal state. As a result, the entire state is as shown in FIGS. 9, 1, and 2, and the work may be started toward the ceiling after the position is fixed on the spot by a stopper provided on each moving wheel.

  In addition, when the work at that place is completed and it is desired to move the place, the work base plate of the scaffold member may be moved through the moving wheel while being horizontally deployed, but the unused storage after the completion of all work. Occasionally, two people hold the levers on the central struts on the front and rear parts of the scaffold member, or two people lift the handle on the front and rear parts of the central member, so that all the work platform plates of the scaffold member are all upright After that, the lock pin is hooked.
