Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention mainly relates to a climbing type all-weather roof for construction work, which makes it possible to avoid bad weather such as wind, rain, and direct sunlight when constructing a medium-sized, medium-rise building. It is.

0002

[Background Art and Problems to be Solved by the Invention] Generally, construction work for RC structures, steel structures, etc. takes a long time, so it is inevitable that the construction work will encounter bad weather such as wind, rain, and intense heat. Work under such bad weather conditions significantly reduces work efficiency, and in some cases, it may not be possible to complete the work at all, which can be a major cause of construction stagnation. In addition, it not only significantly reduces the accuracy of work such as welding that is easily affected by the weather, but also poses a danger.

[0003] For this reason, in recent years, methods have been implemented such as erecting a simple roof such as a tent roof over the head, or constructing the floor of the roof first and using it as a roof. It can only be used during the partial construction period, and cannot be used until the construction of the ground floor. There is also a risk of damage caused by gusts of wind. On the other hand, the latter can only be used for the construction of steel structures, and cannot be used for other constructions such as RC structures, so there is a natural limit to the range of its use.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and can be used as a roof for all stages of construction work. To provide a climbing type all-weather roof for construction work, which can be secured at any position, is easy to assemble and dismantle, and also has the function of an external scaffold.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the climbing type all-weather roof for construction work according to the present invention includes assembling an external scaffold around the outer periphery of the structure, and installing a plurality of elevating towers on the external scaffold. As the structure is extended to the upper floor, it is built while being expanded, and a lifting device that can be raised and lowered is installed on each lifting tower, and a guide rail is installed along the structure between the lifting devices, and a guide rail is installed along the structure. It is constructed by installing a traveling device and installing a movable roof on the traveling device. Further, the movable roof is configured to be foldable by constructing a plurality of truss roofs, stretching a wire rope between the truss roofs, and installing a tent thereon.

[0006]

[Embodiment] The present invention will be described below based on an illustrated embodiment. An external scaffold 2 is assembled around the outer periphery of a structure 1 to be constructed (see FIG. 1).

[0007] The external scaffold 2 is assembled so as to surround the structure 1 by installing a plurality of torii forms 3 while connecting them vertically and horizontally with connecting pins. Further, this external scaffolding 2 is one that is sequentially extended upward as the structure 1 is extended upward, and has been widely used in the past.

Of the external scaffolding 2, lifting towers 4, 4 are installed at predetermined intervals in the external scaffolding 2, 2 in the girder direction (see FIGS. 1 and 2), and the lifting tower 4 is equipped with a rack gear 5. , 5 and guide rails 6, 6 are installed continuously in the vertical direction (see Figures 4 and 5).

The lifting tower 4, the rack gears 5, 5, and the guide rails 6, 6 are divided into a plurality of parts in the vertical direction, so that they are made into a unit with a height that approximately corresponds to the torii formwork 3. As the external scaffolding 2 is expanded, the external scaffolding 2 can be successively expanded to increase its height by connecting them with connecting pins and stacking them upward.

[0010] Each unit of the elevating tower 4 is constructed in the form of a framework through which the torii formwork 3 can be freely passed.
The scaffolding pipes 7 and clamps 8 are used to connect and fix the units integrally, and by laying cloth plates 9, 9 on the upper end of each unit, the units also function as part of the external scaffolding 2.

[0011] In each elevating tower 4 configured in this way,
Lifting devices 10 are installed respectively (Figs. 4, 5, 7).
reference ). A pinion gear 11 is attached to the lifting device 10 in mesh with the rack gears 5, 5, and
Guide rollers 12 and 13 that can run on guide rails 6 and 6 are attached. Furthermore, pinion gear 11
A geared motor 14 is attached to transmit power to. The lifting devices 9, 9 installed on each lifting tower 4, 4 are horizontally connected by a connecting beam 15,
A guide rail 16 is laid on this connecting beam 15.

Note that a lattice beam or a truss beam is used for the connecting beam 15 in consideration of weight reduction, and the guide rail 16 is formed in a substantially groove-like cross section opening directly above. Further, the connecting beam 15 and the guide rail 16 are formed into a unit by being divided into a plurality of parts in the longitudinal direction, and can be freely extended by connecting a plurality of units with a connecting pin or the like.

A plurality of traveling devices 17 are provided on the guide rail 16.
, 17 are installed, and frames 18, 18 are installed on these lifting devices 17, 17, respectively (Fig. 4,
5).

Each traveling device 17 includes traveling wheels 19, 19 that can run smoothly on the guide rail 16, and a geared motor 20 that transmits power to the traveling wheels 19, 19.
Hanger rollers 21, 21 and horizontal rollers 22, 22 for preventing the traveling wheels 19, 19 from lifting up, lateral vibration, and warping, and locking devices 23 for fixing the traveling device 17 in a fixed position are respectively attached. There is. As the locking device 23, for example, as shown in the figure, there is a locking screw screwed into the traveling device 17 so as to press the side surface of the connecting beam 15.

A movable roof 24 is installed between the frames 18, 18 so as to straddle the top of the structure 1 right beside it. The movable roof 24 has two or more roof trusses 25, 25 installed in parallel between the frames 18, 18, and the roof trusses 25
, 25, a plurality of wire ropes 26, 26 are stretched between them, and a tent 27 is placed on top of these wire ropes 26, 26.
(Figures 2, 3, 4, 5)
reference) .

The roof truss 25 is made into a unit by dividing it into a plurality of parts, and the required span can be obtained by increasing or decreasing the number of units as necessary. The area partitioned by the roof trusses 25, 25 is considered as one unit of the movable roof 24, and this unit can be freely increased or decreased. Therefore, the area of the movable roof 24 can be freely increased or decreased according to the scale of the structure 1. can.

Furthermore, by using a structure in which a wire rope 26 is stretched between the roof trusses 25 and a tent 27 is stretched over the wire rope 26, one roof truss 25 can be drawn toward the other roof truss 25, Therefore, the movable roof 24 can also be folded freely.

[0018] Instead of stretching the wire rope 26 between the roof trusses 25, 25, a support jack 28 is installed to introduce tension to the tent 27, or by simply installing a purlin material, it is possible to intentionally fold the tent 27. It is also possible not to have an expression structure.

Further, in the figure, the reference numeral 29 is an auxiliary roof (
(See Figure 4). This auxiliary roof 29 is necessary to cover the outer periphery of the structure 1 because it is almost impossible to completely cover the outer periphery of the structure 1 with the movable roof 24 alone. It is attached in a removable manner. Further, the auxiliary roof 29 is rotatably attached by a pin 31 of a clamp 30, and is easily attached by an arm lock 32. sign 33
is a rain gutter.

Next, the assembly method will be explained. As the construction of the structure 1 progresses, the external scaffolding 2 is assembled to a required height, and the lifting towers 4, 4 are assembled to the same height as the external scaffolding 2. Furthermore, lifting devices 9, 9 are installed on each lifting tower 4, 4, respectively. By installing the lifting device 9 at ground level, subsequent work can be performed on the ground. In addition, a connecting beam 15 is provided between the lifting devices 9 and 9.
A guide rail 16 is laid on this connecting beam 15, and traveling devices 19, 19 are placed on this guide rail 16.
Set up. Further, the movable roof 24 is assembled by installing the frame, the roof truss 25, the wire rope 26, and the tent 27 in this order, and finally the auxiliary roof 29 is installed.

[0021] As the structure 1 is extended, the external scaffolding 2 is expanded by adding two or more stages of torii formwork 3. Further, the elevating towers 4, 4 are expanded by adding units corresponding to the addition of the external scaffolding 2. Furthermore, the movable roof is raised by raising the lifting devices 19, 19. below,
Similarly, as the construction of structure 1 progresses, movable roof 2
4 will also rise.

On the other hand, in order to dismantle the movable roof 24, the entire movable roof 24 is pulled up to the end of the guide rail 16, folded, and removed by a crane in the folded state. In addition, auxiliary roof 2
9 will also be removed.

Next, the lifting devices 19, 19 are lowered, and the torii formwork 3 and the lifting tower 4 units are removed one by one from above. Finally, the traveling device, guide rail, and lifting device are removed from the ground.

Furthermore, as shown in FIG. 9, the movable roof 24 may overlap the external scaffolding 3 and the auxiliary roof 29 may be omitted, or it may be a cantilever method as shown in FIG. . Furthermore, the system is not limited to the mesh drive system using a rack gear and a pinion gear, but may also be a winch drive system using a sheave and a wire rope, or a system in which the system is moved up and down while being rearranged using a hydraulic jack.

[0025]

[Effects of the Invention] Since the present invention has the above structure, it has the following effects.

■ Multi-story buildings can be constructed with a roof up to the top floor, and the entire outer periphery can be constructed with a roof and enclosure, so there is no exposure to wind, rain or intense heat. Therefore, construction can be carried out under an extremely favorable working environment. Therefore, workability is high and work safety is also improved.

[0027] In addition, it is possible to prevent construction materials such as steel frame members from rusting due to wind and rain and from deterioration of construction accuracy such as welding accuracy, so it is possible to prevent reduction in strength due to rusting or poor construction, and stains on the external wall surface. worries can be resolved.

[0028] Also, since the construction work will not be interrupted due to weather, the construction work can be carried out according to the schedule, making it possible to shorten the construction period. In addition, it will become possible to have a full two-day work week, which will contribute to measures to promote employment through labor improvements.

[0029]Furthermore, since the movable roof has a structure that can be easily folded, the opening necessary for unloading cargo can be easily provided at any position, and all main components such as the lifting tower are Because it is unitized, it can be easily assembled, dismantled, and dismantled.
