DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed features of the present invention will be described with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a perspective view showing an installation state of a movable roof movable support device according to the present invention, and FIG. 2 is a side view showing the same purpose. The present inventor has developed a temporary roof with a lightweight and large span that covers the construction site from above at the construction site,
A pair of parallel main beams 1, 1 and a large number of elastic strips 2 arranged obliquely intersecting with the main beams 1, 1 are rotatably connected to each other at each intersection. At the same time, the lattice frame 3 pivotally attached to the main beams 1, 1 at the edges contacting the main beams 1, 1 and the elasticity at the center of the lattice frame 3 parallel to the pair of main beams 1, 1 A convex curved surface is provided to a frame composed of the strip 2 and the central beam 4 pivotally connected to form a shell structure, and a translucent roof coating 5 is provided with a tensile force on the upper portion of the frame to cover the frame. A pair of unit roofs m and n are joined such that one end of each is formed as a ridge 6 at a joint. Such a temporary roof can provide a large space for construction work inside because it is lightweight and has a large span, but at the same time, the girder direction orthogonal to the span direction has a relatively short length. For this reason, it is often the case that several temporary roofs are arranged in parallel to cover the construction space at one construction site.

Accordingly, one temporary roof q arranged on the frame scaffolds 10 and 10 assembled on both sides of the construction space is slightly smaller than the other temporary roof p arranged in the girder direction. If the temporary roofs p and q are slid in parallel in the girder direction and arranged in parallel, in the case of rainy weather, the temporary roofs p and q cover the entire construction space and protect the rain. On the other hand, when it is necessary to carry in and out equipment necessary for building construction, the temporary roof p, q is slid and the temporary roof p is nested in the temporary roof q to form a framework. It is possible to form an equipment loading / unloading port from above without the provisional roofs p and q between the scaffolds 10 and 10. The present invention provides a movable support device for a temporary roof that can be moved smoothly and safely in such a movable temporary roof, and the details thereof will be described below.

In FIG. 3, reference numeral 1 denotes a main beam on one side of a temporary roof p having a slightly smaller size. Main beam 1
Is formed of an angle steel, and at the lower end thereof, a support leg 12a having an H-shaped cross section is fixed upright. Support leg 12a
Is a protruding piece 14a having a mounting hole 13a formed therein.
It has been. The support legs 12a are provided at any of the lower ends of the four main beams 1 located at the four corners of the temporary roof p. On the other hand, reference numeral 12b denotes a support leg fixed to the main beam of a temporary roof q (the temporary roof main body is not shown) having a size capable of accommodating the temporary roof p therein. The support leg 12b has the same structure as the support leg 12a except that the length of the leg is longer than that of the support leg 12a. It is a piece 14b. The support legs 12b are provided at four locations at four corners of the temporary roof q. In a device for slidably supporting these support legs 12a, 12b, a base member 20 mounted on a framed scaffold 10 is provided.
As shown in detail in FIG. 4, is formed by an upwardly directed channel member, and has a length that spans the entire length of the frame scaffold 10 on both sides supporting the temporary roof.
In order to reinforce the long base member 20, reinforcing strips 21 and 21 are provided on both sides in the longitudinal direction lower surface of the base member 20, and a predetermined distance in the longitudinal direction perpendicular to the reinforcing strips 21 and 21 in the width direction. The reinforcement rib 22 is fixed. Further, in order to directly attach the base member 20 to the framework scaffold 10, leg pipes 23, 23 fitted and fastened to the top vertical member of the framework scaffold 10 are vertically provided at predetermined intervals in the lower surface length direction. .

On the upper surface of the base member 20, the temporary roof p is nested with the temporary roof q to fit the temporary roof q.
A pair of rail members 24, 24 are fixed along the length direction at intervals so that the support legs 12a of the temporary roof q can be separately supported by the support legs 12a. Even if the number of temporary roofs is three or more, it is usually sufficient to provide two pairs of rails. However, there is a case where only one set is installed or three or more sets are installed as needed. The rail member 24 is formed of a flat material having a low coefficient of friction. However, it is preferable that the rail member 24 be formed of a synthetic material in which a stainless steel sheet having a low friction coefficient and a hard and smooth surface is attached to an upper surface of a flat steel material. The supporting member 25 which is mounted on the pair of rail members 24 and 24 of the base member 20 and movably supports the temporary roofs p and q with respect to the fixed base member 20 includes the temporary roof p or In order to mount the two support legs 12a, 12a or 12b, 12b on one side of q, two are set on a pair of rail members 24, 24. Each of the support members 25 has a low-friction foot sliding plate 27 such as a polytetrafluoroethylene sheet adhered to both sides of the lower surface of the rectangular support plate 26 at positions corresponding to the pair of rail members 24, 24. The support plate 26 placed on the rail member 24 can be easily slid, and the support legs 12 of the temporary roof p are provided on the upper surface of the support plate 26.
A or a joint piece 29 having an attachment hole 28 to be joined to the support leg 12b of the temporary roof q is formed upright.

Therefore, as shown in FIG. 3, the support legs 12a of the temporary roof p are connected to the right support plate 26 in FIG.
The upper joint piece 29 is joined by bolting so that the mounting hole 13a of the protruding piece 14a matches the mounting hole 28 of the joint piece 29, and the support leg 12b of the temporary roof q is connected to the left side in FIG. The projecting piece 14b is attached to the joining piece 29 on the support plate 26.
The mounting holes 13b are aligned with the mounting holes 28 of the joining pieces 29 and are joined by bolting. In this way, all the supporting legs 12a and 12b at the four corners of the temporary roofs p and q correspond to the supporting members. 25 and is movably supported. To prevent two adjacent sets of support members 25 from escaping from the base member 20 in the circumferential direction, the base member 2
L-shaped covering members 30, 30 for covering the outer surfaces of the upper surfaces of the support plates 26, 26 of the support members 25, 25 from above, are provided on both side flanges of the support member 25, and both center portions of the base member 25 T-shaped covering members 31 that cover the insides of the upper surfaces of the support plates 26 and 26 from above are attached along the length direction, respectively.
With this configuration, even if the temporary roof p,
Even if the supporting member 25 joined by the movement of q is moved up, down, left and right, the supporting plate 26 of the supporting member 25 may be moved.
Collides with any one of the base member 20, the L-shaped covering member 30, and the T-shaped covering member 31 to restrict the movement thereof, and does not cause a situation in which the temporary roofs p and q are blown off. .

The two supporting plates 26, 26 of the base member 20
A hole corresponding to the center position was drilled at a predetermined interval in the longitudinal direction, a nut 32 was welded to the hole to form a screw hole, and a holding plate 33 was fixed to the tip of the screw hole. A fastening screw 34 is screwed. With this configuration, if the temporary roofs p and q are moved, stopped at a predetermined position, and the fastening screw 34 is screwed, the holding plate 33 at the tip of the fastening screw 34 rises, and the support member is raised. 25, the upper surface of the support plate 26 is pressed against the L-shaped cover member 30 and the T-shaped cover member 31, and the support member 25 and the base member 20 are pressed.
Is in an engaged state, and the relative movement between the two is not allowed. By such an operation, the temporary roofs p and q can be maintained in a fixed state at a predetermined position of the base member 20, and the temporary roofs p and q Thus, it is possible to prevent the occurrence of an unexpected accident due to the start of unexpected sliding.

When the temporary roofs p and q are placed on the base member 20, the temporary roofs p and q formed in a gable shape tend to be deformed in a direction in which the spans are widened. For this purpose, the support plate 26 of the support member 25 disposed in the base member 20 projects outward and the L-shaped cover member 30 or T
In some cases, the temporary roofs p and q may not move smoothly due to contact with the character-shaped cover member 31. In order to cope with such a situation, a side edge of the support plate 26 opposite to the side where the temporary roofs p and q are located is bonded to a side sliding plate 35 having a low coefficient of friction such as a polytetrafluoroethylene sheet. A piece 36 is fixed, and a side sliding piece 37 made of a stainless steel plate or the like is attached to a side surface of the L-shaped covering member 30 or the T-shaped covering member 31 facing the piece 36. With this configuration, the side sliding plate 35 on the side piece 36 of the support plate 26 comes into contact with the side sliding strip 37 of the L-shaped covering member 30 or the T-shaped covering member 31, and the contact surface Is reduced, and the support member 25 can be smoothly slid on the rail member 24 of the base member 20.

As described above, the temporary roof movable support device according to the present invention is generally used while being mounted on the framework scaffolding 10 installed on both sides of the construction site. FIG. 1 shows a framework scaffold 10 having a height of one step,
It goes without saying that, depending on the height of the building to be constructed, it is mounted and used on the frame scaffold 10 assembled in multiple stages. It is also possible to use other supporting structures instead of the framework scaffold 10. Since the temporary roofs p and q on the movable support device are lightweight, and the resistance such as frictional force against sliding in the movable support device is small, the temporary roofs p and q are moved by human power or slight mechanical force. It can be done easily. Rain on the temporary roofs p, q
Flows down onto the base member 20 along each of the main beams 1, but since the base member 20 is formed of a channel material, it serves as a gutter and can guide rainwater outward. .
In addition, when the temporary roof p is formed smaller than the temporary roof q and the temporary roof p can be nested in the temporary roof q, the respective roof surfaces of the temporary roof p and q Even if the temporary roofs p and q are widened to cover the entire construction site, rainwater may enter the interior from the steps, but the temporary roofs p and q are stretched on the temporary roof q. The translucent roof coating 5 has a size extending outward from the outer edge of the main beam 1 and the edge of the translucent roof coating 5 is suspended from the outer edge of the main beam 1 of the temporary roof q. By reaching the roof surface of the temporary roof p, such intrusion of rainwater can be prevented.
