[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain avoiding device for a frame scaffold, which enables a construction work to be performed even in the rain by installing a rain avoiding tent on the upper end of the frame scaffold.

[0002]

2. Description of the Related Art At a construction site, a large number of building frames are vertically extended along a structure of a building under construction, and scaffold boards are installed between the building frames to assemble a frame scaffold, and the building is constructed from the frame scaffold. I go in and out of the body to do interior work, and I do exterior work on the outer surface of the building body.
Since the scaffolding board gets wet and the suspension becomes bad, which is dangerous, there is no choice but to limit the above work, resulting in a problem that the construction period is prolonged.

Therefore, conventionally, a rain pipe is formed by laterally fixing a fixed pipe to the upper end of a building frame and providing both ends of the fixed pipe with engaging portions for engaging a rain tent. Is being considered.

[0004]

According to the above construction, since many types of building frames with different widths are manufactured, it is necessary to manufacture many types of rain avoiding devices accordingly, and the manufacturing cost is high. There is a drawback

In view of the above-mentioned conventional problems, the present invention provides rain avoidance on a frame scaffolding in which a rain avoidance tent can be easily attached to various building frames having different widths by preparing one kind of rain avoidance device. The purpose is to provide a device.

[0006]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The present invention is directed to a central tube body 7 and a tube body 7 of the central portion. One end side tube main body 8 which is extendably inserted into one end side and can be locked at a required expansion and contraction position, and the other end side of the central part tube main body 7 is expandable and contractable and can be locked at a required expansion and contraction position. The other end side pipe main body 12 is provided, and the one end side pipe main body 8 and the central portion pipe main body 7 are pivotally attached to the upper ends of the building frames 4 of the frame scaffolds 2, and the both ends are attached. The pipe bodies 8 and 12 are provided with engaging portions 14 and 15 for engaging the rain avoiding tent 13, and
At both ends of the central tube body 7 project inward
The stoppers 20 and 21 formed as
The outer peripheral surface of each of 8 and 12 is almost the entire length in the longitudinal direction.
It is slidably engaged with the groove 22 and 23
And the strikes on the inner ends of both the concave grooves 22 and 23.
The configuration in which the top contact portions 22a and 23a are formed is adopted.

[0007]

In the above structure, when the upper surface of the frame scaffolding 2 is covered with the rain avoiding tent 13, a large number of building frames 4 are vertically extended along the building frame 1 and scaffolding between the building frames 4 is performed. The plate 5 is erected to form the framework scaffold 2, and then the required length of expansion and contraction is adjusted by adjusting the insertion length of the one end side pipe body 8 inserted into one end side of the central portion pipe body 7 of the rain avoiding device 3. By locking to the central pipe body 7 at the position, the facing distance α between the two mounting legs 9 and 10 pivotally attached to the two pipe bodies 7 and 8 is adjusted to the width β of the building frame 4. After that, both mounting legs 9,
10 is connected to the uppermost building frame 4 of the framework scaffold 2. Then, after adjusting the insertion length of the other end side tube body 12 inserted into the other end side of the central part tube body 7 and locking the central part tube body 7 at the required expansion / contraction position, both end sides It suffices to engage the rain avoiding tent 13 with the engaging portions 14 and 15 provided on the pipe bodies 8 and 12, and in this case, by preparing only one kind of the rain avoiding device 3, various types of buildings having different widths β can be obtained.

It is necessary to adjust the orientations of both engaging parts 14 and 15 when moving
There is no need to install the tent 13 easily and quickly. Ma
In addition, the end side tube bodies 8 and 12 are extended with respect to the central tube body 7.
When lengthened, each stopper 20, 21 has a groove 22,
Since it abuts on the abutting portions 22a and 23a of the inner end portion of 23,
The end side pipe bodies 8 and 12 unexpectedly come out of the central portion pipe body 7.
Can be prevented. Also, the stoppers 20 and 21 are
As described above, whether each end side tube body 8 or 12 is the central tube body 7
Along with the function to prevent it from coming out, the central tube body 7
The rotation of each end side tube body 8 and 12 with respect to
It also has the function of guiding the axial movement of the pipe bodies 8 and 12.
Use a stopper to pull out and a stopper to prevent rotation.
Separately, a guide for axial direction and a guide for axial direction are installed separately.
There is no need to kick.

According to the present invention, it is possible to adjust the insertion length of the tube body on one end side and lock it on the central tube body at the required expansion / contraction position, and to pivot both tube bodies. Since the opposing distance between the mounting legs can be adjusted according to the width of the building frame, and both mounting legs can be connected to the building frame, it is only necessary to prepare one type of rain avoiding device of the present invention, and various widths different from each other. The rain tent can be easily attached to the building frame, and the production cost can be reduced. Further, since the both mounting legs are pivotally attached to the both pipes, it is possible to mount the rain avoiding tent on the building frame at an appropriate inclination angle and drain the rain falling on the tent in a desired direction. .

Further, the stoppers of the central tube body are provided on both end sides.
Since it is fitted in each groove on the tube body,
Circumferential rotation is prevented and both engaging parts are always the same.
A tent that can be positioned upwards and is therefore a rain shelter
It is necessary to adjust the orientation of both engaging parts one by one when installing
Without the tent, you can easily and quickly install the tent
It Also, extend each end-side tube body with respect to the central tube body.
Each stopper contacts the contact part of the inner end of each groove when
As a result, each end side pipe body unexpectedly comes out from the central pipe body.
There is no danger of coming out, and installing or dismantling the rain avoidance device
The safety of time can be secured. Also, each of the above stoppers,
Prevents each end tube body from slipping out of the central tube body
In addition to the function, the rotation of each end side pipe body with respect to the central pipe body
Function to prevent rolling and guide axial movement of each end side tube body
Since it has both, it is a stopper for getting out,
A stopper to prevent rotation and a guide for axial guidance
Need not be provided separately, so the structure is
It is simple and easy to manufacture and assemble. Furthermore, when not in use, both ends of the tube body can be stored in the central tube body in a contracted manner as much as possible, and the mounting legs can be folded along the central tube body to make it compact. It is convenient for storage.
