 In the case of temporary scaffolding for conventional construction work, in the case of rain, the top tier of the scaffold is used to stretch the awning, and the scaffold passage below it is used to carry in the building equipment. We are trying to streamline the work.

However, since the attachment of the awning is to connect the eyelet to the scaffolding pipe by passing the string through the eyelet, it is extremely complicated and takes extra man-hours to attach and remove the awning according to the weather. Therefore, in addition to the problem that work efficiency does not increase, it is impossible to completely prevent rain leaks by using this conventional method, so it is difficult to carry in construction equipment and perform peripheral work such as caulking painting in rainy weather, resulting in construction. There were problems such as delay in construction period and increase in construction man-hours, resulting in extremely large economic loss. In order to eliminate such drawbacks, the applicant has developed a temporary scaffold with an awning sheet attached, and first applied for a utility model registration. However, although the above drawbacks are eliminated, this one has problems that it is extremely troublesome to fix the awning sheet at a desired position at a desired angle, and to attach and detach the awning sheet, and it is still not practically satisfactory. Not kimono.

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of the present invention, in which a pillar 3 of a building frame is passed between shaped steels of guide rails 1 formed by arranging shaped steels having a substantially C-shaped cross section in a back to back direction. A bracket 7 is fixed to the lower end of the drail 1 so as to face the lower end, a long hole 11 is provided in the longitudinal direction of the bracket 7, and a pipe (5) integrally provided with a pin (projection) 6 that slides into the long hole 11. Is connected between the brackets 7, the pipe 5 and the pillar 3 of the building frame are connected by two continuous clamps 4, and a through hole 10 is formed at the tip of the guide rail 1 and fastened to the pillar 2 of the building frame. An example is shown in which the metal fitting 9 attached to the clamp 8 is placed between the shaped steels of the guide rail 1 and pins are inserted and fixed in the through holes of the metal fitting 9 and the through holes 10 of the guide rail 1.

As shown in FIG. 2, the awning seat 12 is sandwiched and fixed to the sliding piece 13 at the front and the rear, and the sliding piece 13 is slidably fitted to the guide rail 1 so that the awning seat 12 is secured. It can be stored on one side or stretched over the entire length. 3 and 4 show another embodiment in which the tip of the guide rail 1 is fixed to the column 2. A bracket 21 is provided at the tip of the guide rail 1 so as to face the inside of the bracket 21. The bush 23 is welded, and the pipe 24 is slidably fitted to the bush 23. The pipe 24 is constructed so that the clamp ring 25 is constantly urged toward the center by the stopper ring 22 and the spring 32. There is.

When the tip of the guide rail 1 is inserted from the pillar 3 of the building frame and reaches the pillar 2, the pillar 2 comes into contact with the taper on the insertion side (arrow side in FIG. 4) of the clamp metal fitting 25 and resists the spring 32. The clamp metal fitting 25 is expanded by pushing the clamp metal fitting 25, and when the clamp metal fitting 25 coincides with the center of the pillar 2, the pillar 2 is held. At the same time, the lever 27 rotates about a fulcrum 28 of the clamp metal fitting 25 and fits into a pin 26 fixed to the clamp metal fitting 25 on the opposite side. Then, when the levers 27 on both sides are pressed, the pin 31 fixed to the clamp fitting 25 and the pin 29 fixed to the lever 27 are connected by the tension spring 30, so that the lever 27 does not loosen and the clamp fitting 25 is not loosened. The column 2 is fastened with and the tip of the guide rail 1 is firmly fixed to the column 2. When the guide rail 1 is pulled out from the support column 2, by opening the levers 27 on both sides, the tension spring 30 acts in the direction to open the lever 27, and the force pulling to the front of the guide rail 1 is applied to the spring 32. Since the clamp metal fittings 25 are pushed and spread apart against each other, the guide rail 1 can be pulled out.

A short pipe 42 is fixed to the clamp 41 fixed to the support 2 through a plate-shaped connecting member 40 in a direction perpendicular to the support 2, and when the openings of the brackets 43 and 46 contact the short pipe 42, The component force in the opening direction acts on the inclined portions of 43 and 46 to swallow the short tube 42. At this time, the pin 47 fixed to the clamp fitting 46 is fitted and fixed in the hole in the lower surface of the short pipe 42, and the return spring 44 urges the guide rail 1 firmly.

FIGS. 7 and 8 show an example in which a guide rail is fixed to a pillar of a temporary scaffold for low-rise buildings, and a short lower end of the guide rail 1 having a short shape has a long hole 50 in the longitudinal direction. A pair of brackets 51 are fixed to each other, and a pipe 54 having pins 53 formed on both sides between the brackets 51 is fixed by inserting the pipe 54 into the long hole 50, and the pipe 54 and the scaffolding pipe 3 are double clamped. The length of the gravity lock 55 provided on the bracket 60 fixed to the upper end of the guide rail 1 and the gravity lock 57 provided on the clamp 58 fixed to the scaffolding pipe 3 can be adjusted. The guide rail 1 can be fixed at an appropriate inclination by connecting with a connecting rod 56. The length-adjustable connecting rod 56 may be formed of, for example, a connecting cylinder.

By fixing the connecting rod 56 whose length can be adjusted as described above and inserting the pin 53 into the long hole 50 so as to be slidable, the tip of the guide rail 1 is inserted under the eaves 59 of the building. It can be easily fixed and the slope in the same direction as the roof slope can be added. As shown in FIG. 9, sliding pieces 67A, 67B, 68A and 68B having the awning sheet 12 sandwiched and fixed thereto are slidably fitted to the guide rail 1 as shown in FIG. It can be fixed by using the thumbscrew bolts 61, 62, 64 provided at the upper end of 1. Therefore, the awning sheet 12 can be unfixed and slidable by loosening the thumbscrew bolts and stored in one side, or can be stretched over the entire length and fixed by tightening the thumbscrew bolts.

[0012] In the shaped steel of the guide rail 1, there is formed a gap through which the support column is passed, and in order to prevent rain leakage from this gap, a gap between the shaped steels, as shown in FIG. 6 is stretched. In the sub-sheet 66, cutouts 2, 3 and 2C, 3C having a shape corresponding to the support pillars and auxiliary support pillars of the building frame, and a cutting line 76 for connecting to the cutouts so that they can be inserted from one direction.
