DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a temporary roof used at a construction site or the like.

[0002]

2. Description of the Related Art Conventionally, a temporary roof used at a construction site is formed as a single piece, and is capable of moving up and down on a plurality of (usually four) columns erected around a building under construction. It is fixed to a plurality of elevating devices that are attached and driven independently of each other, and are laid across the building.
In addition, the temporary roof may be a roof unit that runs on a track attached to the girder direction of the building under construction, or a roof such as a curtain on a frame that is bridged between beams of the building under construction. Some materials are unrolled / rolled. The temporary roof may be directly installed on a building under construction.

[0003]

However, the above-mentioned conventional temporary roof has the following problems. The temporary roof is formed as a single piece, fixed to a plurality of independently driven lifting devices arranged around the building, and spans the building. Therefore, when raising the temporary roof, it is necessary to adjust the position of each elevating device while maintaining a balance so as to keep the temporary roof horizontal, which is cumbersome and reduces the efficiency of construction work. The temporary roof is supported by a plurality of columns erected around the building under construction and is erected across the building or directly installed on the building under construction. Therefore, after the building is completed, the temporary roof cannot be removed as it is, and it is necessary to dismantle and then remove it. At this time, the work of dismantling the temporary roof is a dangerous work because it is performed at a high place. Even if the temporary roof is opened at the time of loading the material, the roof unit or the frame hung in the direction between the beams remains as it is, which hinders the loading of the material. Since a roof unit or a roofing material that matches the length of the building in the direction between beams is required, it is not versatile. Since the temporary roof is attached integrally across the building, if there are high and low points in the building, the height position is set according to the highest point. Become. Therefore, when the height difference between the high part and the low part of the building is large, a useless space is created between the temporary roof and the low part of the building.

It is an object of the present invention to provide an openable / closable temporary roof that can be moved up and down independently of a building, does not hinder the introduction of materials, and has versatility.

[0005]

According to a first aspect of the present invention, there is provided an opening / closing temporary roof, which is erected on one side of a building under construction with an interval from the building. And a lifting table that is attached to the column so as to be able to move up and down, and that raises and lowers the column by a mounted lifting device. A roof that is rotatably attached to the elevator with the other hinge side of the part by another hinge, and that is opened or closed above the building by being folded or opened by an opening / closing device mounted on the elevator. It is characterized by having a frame.

A second aspect of the invention is characterized in that a plurality of the openable temporary roofs according to the first aspect of the invention are arranged side by side.

According to a third aspect of the present invention, there is provided an openable temporary roof according to the first or second aspect,
At least one of the columns is a tower crane column.

[0008]

According to the first aspect of the invention, when opening and closing the openable temporary roof, each of the two divided parts is hinged by an opening / closing device mounted on an elevating table attached to the column so as to be movable up and down. A foldable roof frame is folded or unfolded to open and close the roof frame. Furthermore, when raising and lowering the openable and closable temporary roof, the lifting platform is moved up and down by the lifting column mounted on the lifting platform arranged on one side of the building. Then, the roof frame, whose one side is rotatably attached to the elevator, is moved up and down together with the elevator.

In the invention according to claim 2, the building to be constructed is completely covered by the openable temporary roof according to the invention according to claim 1 in which the buildings are arranged in a number corresponding to the size of the building. At this time, if there are a high place and a low place in the building, the high place and the low place are covered with different roof frames at optimum heights.

According to the third aspect of the present invention, a building material is carried in from an open roof frame by a tower crane which also serves as a column and a column of the openable temporary roof. In this way, the work can be performed efficiently with fewer columns around the building.

The second frame 4b is rotated downward by its own weight about the hinge 11 as a center of rotation, and is folded as shown in FIG.

Therefore, in the temporary roof according to the present embodiment, when the roof frame 4 is opened, there are no obstacles such as frames above the building 8, and there are obstacles which hinder the material transport by the tower crane 6. do not do.

When the roof frame 4 is closed, the opening / closing device 5 may be operated in the reverse manner as described above.

The elevating device mounted on the elevating table 3 includes a pinion gear 28 meshing with the rack gear 15 provided on the column 2, a pinion driving means 29 for driving the pinion gear 28, and a pinion driving means 29. A lift control device 30 for controlling the driving direction and the like; a guide roller support 31 provided on the upper and lower portions of the lift 3 so as to face four surfaces of the support 2; and a support for the support 2 supported by the guide roller support 31. It is roughly composed of guide rollers 32 rolling on four surfaces.

In the above configuration, when the lift 3 is raised, the pinion drive means 29 rotates the pinion gear 28 in the upward direction under the control of the lift controller 30. In this way, the lift 3 to which the pinion driving means 29 is fixed is guided by the guide rollers 32 rolling on the four surfaces of the column 2, and smoothly rises along the column 2. Further, by rotating the pinion gear 28 in the descending direction under the control of the elevation controller 30, the elevator 3 smoothly descends along the column 2.

As described above, the temporary roof 1 in this embodiment is provided with the lift 3 on one of the columns 2 erected on one side of the building 8 and hinges one side of the roof frame 4 to the lift 3. 1
2 so as to be freely rotatable. Then, the roof frame 4 is folded / removed by appropriately winding / sending out the wires 13 and 14 with the first winding drum 21 and the second winding drums 22 and 22 of the opening / closing device 5 provided on the lift 3. Open and open. In addition, the pinion driving means 29 of the lifting device provided on the lifting table 3 rotates the pinion gear 28 meshed with the rack gear 15 of the support column 2 to move the lifting table 3 up and down. That is, the roof frame 4 is installed so as to cover the building 8 by the elevating platform 3 installed on one support column 2 erected on one side of the building 8. As a result, when the roof frame 4 is raised, as in the case of a conventional temporary roof which is formed integrally and erected over the building, the height of all the lifting devices arranged around the building is reduced. There is no need to balance. Therefore, the roof frame 4 can be easily raised in units of the roof frame.

The roof frame 4 is folded without being dismantled by a lift 3 which is attached to a column 2 which is provided on one side of the building 8 on the outer side of the building 8 at a distance from the building 8 so as to be able to move up and down. Can be dropped on the ground in the state. Therefore, the work of dismantling the temporary roof 1 when the building is completed is safe.

The roof frame 4 is composed of a first frame 4a and a second frame 4b rotatably connected by a hinge 11, and both frames 4a, 4b are provided on one side of the first frame 4a. Hinge 12 and hinge 1
1 is opened while being folded about the center of rotation. Therefore, when the roof frame 4 is opened, there is nothing on the building 8 that hinders material loading.

Also, of the plurality of temporary roofs 1, 1,... Covering the building 8, only the roof frame 4 of the corresponding temporary roof 1 is opened by adjusting the folding angle of the roof frame 4. Only limited parts can be opened.

Further, the length of the entire temporary roof can be adjusted by arranging a plurality of temporary roofs 1 each including the support column 2, the lifting platform 3, the roof frame 4, and the opening / closing device 5. Therefore, according to the present embodiment, a temporary roof having divertability can be easily realized. Further, by covering the building 8 with a plurality of temporary roofs 1, 1,..., The demolition work can be performed on an individual temporary roof basis. Therefore, even in a large building 8, the temporary roof can be dismantled very easily. Further, the building 8 is connected to a plurality of temporary roofs 1, 1,.
Each roof frame 4 can be lifted independently of the other roof frames 4 by the individual lifting devices even when the roof frame 4 is covered with the roof frame. Therefore, it is not necessary to raise all the roof frames 4 at the same time when the roof frames 4 are raised with the progress of the construction work, and the roof frames 4 can be easily raised in units of each roof frame.

When the building 8 has a high place and a low place, the high place and the low place are covered with different roof frames 4, so that each place has an optimum height according to its height. Can be covered with Therefore, no useless space is generated between the roof frame 4 and a low part of the building 8.

In the above embodiment, one end of the wire 14 for suspending the second frame 4b is attached to the upper edge of the joining surface of the second frame 4b, but it is attached to the tip of the second frame 4b. No problem.

[0030]

As is apparent from the above description, the openable temporary roof according to the first aspect of the present invention is provided on a column which is erected on one side of a building under construction with an interval from the building. A lift frame is attached so as to be able to move up and down freely, and a roof frame that is folded / expanded by an opening / closing device mounted on the lift table to open and close the upper part of the building is rotatably attached to the lift table. Can be moved up and down by the elevator arranged on one side of the building. Therefore, according to the present invention, it is necessary to adjust the position of the elevating devices arranged on both sides of the building when ascending, as in the case of the conventional temporary roof which is formed integrally and erected over the building. Absent. As a result, as the work floor rises, the building work can be efficiently performed by simply ascending the roof frame unit located on one side of the building, and can be safely folded down during dismantling. Further, since the roof frame is folded by the opening / closing device to completely open the upper part of the building, the roof frame is not obstructed when carrying building materials.

[0031] Further, in the openable temporary roof according to the second aspect of the present invention, a plurality of the openable temporary roofs according to the first aspect are arranged side by side. By setting, even large buildings can be completely covered. Therefore, according to the present invention, it is possible to provide an openable / closable temporary roof having divertability. Furthermore, even if there are a high place and a low place in a building covered by the plurality of roof frames arranged side by side, the low place of the high place can be covered with a different roof frame at an optimum height. Therefore, no useless space is generated between the building and the roof frame.

According to the third aspect of the present invention, since at least one of the columns is a tower crane column, the number of columns erected around the building is reduced to reduce the number of columns. The surrounding complexity can be reduced.
