DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be specifically described with reference to the drawings. FIG. 1 is a conceptual diagram of a temporary tent U targeted by the present invention. This temporary tent is an upper and lower mast P that can be raised and lowered as a lower support disposed on the outer periphery of the site of the structure to be constructed or the upper surface of a pair of left and right external scaffolds S that are sequentially stacked and installed on the outer periphery of the site. Is removably installed (see FIGS. 2 to 4).

The temporary tent loading device of the present invention is orthogonal to the basic girder between a pair of basic girders 10 and 10 which are supported by the lower support and are arranged in parallel so as to sandwich the planned structure. The hoist girder 11 is disposed in a substantially horizontal state by a pair of columns 12, 12 which are arranged in a facing direction and which are erected on each foundation girder. Hoist girder 11
The temporary tent U is supported by a hanging member composed of a pillar 13 vertically suspended from the mountain frame ridge and a tie rod cable 14 suspended obliquely downward from the mountain frame. A hoist crane indicated by reference numeral 15 is mounted so as to be movable along the direction of travel of the hoist girder 11.

5 to 8 show the details of the loading device. In the present embodiment, as an example, two sets of lifting masts P are built at the four corners of the outer periphery of the planned structure.
A base girder 10 which can be raised and lowered is fixed to the lifting mast P so as to sandwich a planned structure to be constructed. The base girder is made of H-shaped steel as shown in the figure, and functions as a joist supporting the temporary tent U. In the present invention, the joist of the loading device is also used. A column 12 for supporting the hoist girder 11 at a predetermined height is attached to the upper surface of the center girder substantially at the center. Then, the hoist girder 11 is fixed in a horizontal state by the left and right columns. Hoist girder 1
Reference numeral 1 functions as a guide rail on which the hoist crane 15 is mounted and which is used for traveling.

Each member such as the hoist girder 11 and the column 12 is formed by using a steel material such as H-shaped steel as the main material similar to the base girder 10 as a main material, and if necessary, a reinforcing metal fitting is used together to fix the base girder. It is fixed to 10 etc. so that it can be removed. Further, a pillar 13 and a tie rod cable 14 are attached to the upper surface of the hoist girder 11. The stanchions are vertically suspended and fixed below the mountain frame ridge of the temporary tent. Tie rod cables are suspended and fixed on the frame of a mountain-shaped tent. Both of these hanging materials improve the bending load and buckling load of the hoist girder, and facilitate the movement of materials inside the tent by the hoist crane.

Here, the structure of the temporary tent U will be briefly described. In FIG. 1, reference numeral 21 is a pair of roof members assembled in a mountain shape, and 22 is a column member fixed to the lower ends of both ends of the roof member. These members form the framework of the temporary tent U, and are all formed by using an aluminum lightweight structural material, and specifically, are formed by an aluminum alloy hollow section member having a substantially rectangular or square cross section.
The roof member and the support member are connected by bolts using an insert fitting (not shown). A plurality of support materials 23 made of a main board material and / or braces are provided at predetermined intervals between the roof members arranged so as to face each other and bolted to form a temporary tent U assembled in a shed.

The temporary tent thus assembled is detachably installed on the upper surface of the lower support arranged on the outer periphery of the site by a crane. A base girder is provided on the upper surface of the vertically movable mast P or the outer scaffold S that is a lower support. It is fixed to the base plate provided on this foundation girder using a pin joint or the like. Also, a purlin or the like is passed between adjacent tents to assemble a temporary tent having a predetermined span as shown in FIGS. After assembling, a flexible sheet material (hereinafter referred to as a roof sheet) 1 is installed in the beam direction of the roof, and if necessary, a sheet is stretched not only on the roof but also on each side wall. It should be noted that a part or all of the flexible sheet material covering the roof surface can be opened or closed mechanically or manually by using an opening / closing mechanism for material loading and the like.

[0015]

As described above, according to the present invention, it is possible to easily carry out the material movement accompanying the progress of the construction by using the hoist crane mounted on the hoist girder. Moreover, all the construction work is done in a temporary tent without being affected by weather such as wind and rain, and is performed in a very good working environment, so workability is high and safety is also high. Further, since the working conditions are improved, the work period can be shortened as compared with the conventional one, which is an excellent effect.
