Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective cover for a building, and more particularly, to a protective cover used in a building process of a reinforced structure.

[0002]

[Prior art]

 Generally, when constructing a multi-story building, a construction method is adopted in which a lower floor is first constructed, then an upper floor is constructed, and then higher floors are constructed in sequence. However, with this construction method, construction work is carried out without a roof, so the progress of work is affected by the weather. Therefore, if bad weather continues, the construction period will be delayed.

As a solution to this problem, the applicant of the present invention has proposed the one described in Japanese Patent Laid-Open No. 5-86651. As shown in FIG. 6, a work table 3 also serving as a rooftop structure is erected on a mast 2 extending from the ground 1, an initial hierarchy 10 is constructed on the work table 3, and then the work table 3 is lifted. Then, it is a construction method in which the next floor is constructed and the higher floors are constructed in sequence.

The workbench 3 is located on the top floor of the structure under construction until the construction is completed, and the materials and personnel are put therein to perform the work. A protective cover 11 is stretched to cover the workbench 3.

The protective cover 11 protects workers and materials from wind and rain, and prevents the construction period from affecting the weather.

[0006]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional one, since the protective cover 11 is formed in a simple box shape, the lower edge of the protective cover 11 is placed on the work table 3 in preparation for the replacement of workers and the transfer of materials. A gap 12 is provided so as to float from above. Then, the material is carried in and out through the gap 12.

[0007] Therefore, there is a risk that construction work may be hindered, for example, wind and rain may invade through the gaps, materials may be damaged, and large materials may be difficult to carry in. The present invention has been made in view of the above matters, and can more surely cover a work place, improve workability in bad weather, and facilitate loading and unloading of materials. It is a technical subject to provide such a protective cover for a building.

[0008]

[Means for Solving the Problems]

 In order to solve the above technical problems, the present invention constructs a reinforcing bar structure by installing a workbench 3 which also serves as a rooftop structure on a mast 2 extending from the ground 1, and the workbench 3 initially After constructing the floors, the workbench 3 is raised to build the next floor, and the protection cover 4 to be stretched over the workbench 3 in the construction method of sequentially building the higher floors is constructed as follows. And

That is, a protective cover body 5 formed in a box shape so as to cover the workbench 3, an opening / closing door 7 formed on a side surface 6 of the protecting cover body 5, and the opening / closing door 7 can be remotely operated. And a remote control unit 8 for opening and closing.

As the protective cover body 5, a lightweight panel or a hood made of a reinforced resin sheet can be used. Further, the opening / closing door 8 can be opened left / right or up / down, and its structure can be an accordion type, a shutter type, or a lightweight panel.

[0011]

[Action]

 The box-shaped protective cover body 5 that covers the workbench 3 has an opening / closing door 7 formed on the side surface 6 thereof, and the opening / closing door 7 can be opened / closed by remote operation, so that the loading / unloading of materials can be performed. If necessary, this can be done by operating the remote control unit 8 to open and close the protective cover body 5.

Further, since the internal airtightness can be enhanced only by closing the opening / closing door 7 at all times, workability in bad weather is greatly improved. Furthermore, it is possible to protect the materials without wind and rain. And, it becomes easier to carry in large-sized materials as compared to conventional ones.

Further, since the opening and closing can be performed remotely, it can be controlled not only from the workbench 3 but also from the first floor of the building or a control room provided separately, so that the opening / closing door 7 can be opened. Operability is good.

As described above, a safe and comfortable working environment can be obtained.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. A mast 2, which is a structure of a building, is erected on the ground 1 and serves as a structure of the structure. A workbench (climbing floor) 3 is vertically erected on the mast 2. The workbench 3 is provided with a power jack so that it can move upward as the construction work progresses.

The workbench 3 finally becomes a structure of the rooftop portion, and is used as a workbench only during construction work. Then, after the work is started on the workbench 3 to build the initial hierarchy, the mast 2 is added, and the mast 2 is raised. Further, in the same way, the next floor is constructed, and the higher floors are constructed in sequence.

The workbench 3 is provided with a box-shaped protective cover body 5 made of a lightweight panel so as to cover the workbench 3. As shown in FIG. 3, the outer periphery of the protective cover body 5 is formed to be larger than the workbench 3, and the height of the protective cover body 5 allows the worker to move freely inside the crane, while the crane operates inside. Is set to a size sufficient for.

Two windows 6 a are provided on the side surface 6 of the protective cover body 5, and an opening / closing door 7 is installed in each of the windows 6 a. This opening / closing door 7 is of an electric accordion type and has a structure as shown in FIG. That is, a rail 7a is provided above the window 6a, and an accordion type opening / closing door 7 is held on the rail 7a via a guide 7b. The guide 7b is fixed to the upper end of the opening / closing door 7 and is configured so that it can be smoothly opened / closed by sliding along the rail 7a.

Two sets of pulleys 7c are provided at the center of the rail 7a, and one set of pulleys 7c is provided at each end of the rail 7a. Two wires 7d are stretched around the pulley 7c so as to be distributed to the left and right, and a guide 7b located at the tip portion is locked to the wire 7d. As a result, when the pulley 7c is rotated, the wire 7d and the guide 7b move, and the opening / closing door 7 opens and closes accordingly.

An electric motor 7e is connected to the pulley 7c, and the opening / closing door 7 can be opened and closed by operating the electric motor 7e. The electric motor 7e is controlled by the remote control unit 8. The remote control unit 8 individually controls the two sets of open / close doors 7, and as shown in FIG. 5, a button 8a for performing open control, a button 8b for performing close control, and a stop button. It is composed of a button 8c for performing control.

As shown in FIG. 4, the remote control unit 8 is provided not only on the first floor of the building but also on a control room (not shown) and the workbench 3 which are separately provided. It can be operated remotely.

The protective cover body 5 may be a lightweight panel or a hood made of a reinforced resin sheet. Further, the opening / closing door 8 can be opened vertically, in addition to the left-right opening described above, and the structure thereof can be a shutter type or a lightweight panel in addition to the accordion type described above.

In the above-mentioned configuration, when it becomes necessary to carry in / out the material, the remote operation unit 8 is operated to open / close the protective cover main body 5 to do this. On the other hand, by closing the opening / closing door 7 at all times, the internal airtightness can be improved, and workability in bad weather is greatly improved. In addition, it is possible to protect the material without wind and rain.

Further, in the conventional case, the workability was poor because the material was carried in from a small gap, but it became easy to carry in a large material because the window could be opened wide. From the above, we were able to obtain a safe and comfortable working environment.

[0025]

[Effect of device]

 According to the present invention, the work area can be surely covered without any gap, so that workability in bad weather is improved. In addition, since the frontage can be widened, it is possible to easily carry in and out the materials and improve the work efficiency. Further, since the opening / closing door can be remotely operated, opening and closing can be performed quickly and easily.
