Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary scaffold provided with a movable roof for facilitating work in a rainy weather at a construction site and not hindering the work in fine weather.

[0002]

2. Description of the Related Art Conventionally, on a temporary scaffold for construction work, in the case of rainy weather, the tent is stretched using the uppermost scaffold, and building equipment is carried in using a scaffold passage below the tent. The tent is removed to improve the efficiency of loading work.

[0003] However, since the mounting of the tent is to tie the eyelet with a string and tie it to the scaffold pipe,
Attachment and removal of the awning according to the weather is extremely complicated and requires extra man-hours, so there is a problem that the work efficiency does not increase.In addition, according to this conventional method, it is not possible to completely prevent rain leakage, During rainy weather, it is difficult to carry out construction equipment and to carry out peripheral work such as caulking painting. As a result, the construction period is delayed, the number of construction steps is increased, and the economic loss is extremely large. Scaffolding devices that cover the entire scaffold with a single roof have been proposed, but since the size of the scaffold varies depending on the building, it could not be applied directly to existing scaffolds, so it was actually used industrially. Not. This was because the scaffolding itself had to be assembled in accordance with the device of the roof part, so that the work was extremely difficult, and it became very expensive, so that it could not be adopted in terms of cost. In order to solve such a drawback, the present inventor has previously developed a temporary scaffold with a roof and applied for a utility model registration (Japanese Utility Model Application No.
-122221). However, although the above-mentioned disadvantages are solved, there is a difficulty in attaching and removing the canopy.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a temporary scaffold having a roof with a very simple structure and a roof that can be easily attached to and detached from an existing scaffold. I do.

[0005]

According to the present invention, there is provided a construction according to the present invention, in which an awning sheet formed to extend and contract on a linear guide rail attached to an opposing support of a building frame is opposed to the guide rail. The guide rail is slidably held and provided at the upper end and / or lower end of the guide rail with a locking means for locking the awning sheet. In rainy weather, the awning sheet is slid and extended to form a canopy. When the weather is fine, the awning sheet is slid and folded in a bellows shape to remove the canopy.

[0006]

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, and FIG. 2 is a front view showing an embodiment of the present invention. As shown in FIGS. 1 and 2, brackets (guide rail fixtures) 2, 2 'are fixed to the columns 1a, 1b of the building frame, and long guide rails 3, 3 made of channel steel are fixed to the brackets. ′
Are fixed by screwing thumb screws 6, 6 'into the brackets 2, 2'.

As shown in FIGS. 3 and 4, the brackets 2 and 2 'hold the channel steels 5 and 5' between the iron plates 4 and 4 'and fix them by welding or the like. A notch (not shown) is fitted to the support and fastened by clamps 12 and 12 'to secure the support to the support. Clamps 12, 12 '
Is constituted by rotatably connecting a fitting having a fixing bolt to one end thereof and a clamp fitting to the other end of the fitting so as to be rotatable. By screwing a nut to the fixing bolt, the nut can be fixedly fastened to the column.

[0008] Guide rails 3,
The guide rails 3 and 3 'are fixed to the brackets 2 and 2' by tightening the thumb screws 6 and 6 'screwed from the through holes of the channel steels 5 and 5' at appropriate positions. ing. By selecting the fixing position of the bracket 2 and the bracket 2 'to the support, the guide rail 3,
3 'can be set to a predetermined inclination angle (15 ° in the above embodiment). As shown in FIGS. 1 and 2, both ends of the awning sheet 11 are slidably mounted in opposing guide rails 3, 3 'attached to the adjacent columns 1a, 1b and 1c, 1d. . Shafts 7 and 8 are fixed to the upper and lower ends of the awning sheet 11, and rollers (slide members) 9, 10 and 9 'and 10' are fixed to both ends of the shafts 7 and 8, respectively. It is slidably fitted to the guide rail and is held by angle springs 15, 15 'fixed in the guide rail. In the above embodiment, the lower end 13 of the guide rail is closed, but the upper end is open.

At the center of the upper end and the lower end of the awning sheet are provided notches 17 and 18, respectively, which act as handles. The notches 17, 18 are used to slide the sheet 11 by hand. I have to. In the above embodiment, the awning sheet is slidably held on the guide rail by the rollers and the chevron springs. However, this is not necessarily the case. It may be a means. For example, the awning sheet is configured as a curtain, the awning sheet is supported on a guide rail so as to be held on a curtain rail, and a fixing member is fixed to the upper end and the lower end of the awning sheet. And the lower end. In this case, one stopper may be fixed to the awning sheet via a spring so that the awning sheet has tension.

[0010]

Next, the operation of the present invention constructed as described above will be described. In order to attach the sheet 11 to the guide rails 3 and 3 ', first, the notches 18 of the sheet are gripped, the rollers 10 and 10' are inserted from the upper ends of the guide rails 3 and 3 ', and the slide is performed by compressing and passing through the chevron spring 15. Then, the guide rails 3, 3 'are locked by the angle spring 15' at the lower end, and the rollers 9, 9 'are locked by the angle spring 15 at the upper end. In this state, conditions are set so that the sheet is in a tight state. When it is raining, it is used in this state. In fine weather, similarly, if the sheet 11 is gripped by the notch 17 at the upper end of the sheet and the sheet 11 is pulled downward in FIG. It abuts and locks on the 'angular spring 15 at the lower end'. In rainy weather, the notch 17 at the center of the upper end of the sheet 11 is gripped, and the sheet 11 is pulled upward in FIG. 2 so that the rollers 9, 9 'slide in the guide rail 3, and the leading ends of the guide rails 3, 3' Reached,
Locked to the angle spring 15.

[0011]

[Effects of the Invention] As described above, according to the present invention, the tent sheet can be easily attached and detached by sliding the tent sheet with the guide rail, so that even an unskilled person can easily do so. In addition, since the canopy can be made quickly and the canopy can be easily removed, the outer peripheral work such as the caulking coating can be easily performed without any trouble even in rainy weather. In addition, according to the present invention, since the guide rails are fixed to the opposing columns, the roof can be easily formed on the entire scaffold regardless of the size of the scaffold and the interval between the scaffolds.
