[Industrial applications]

 The present invention relates to a building roof, and more particularly to a roof for constructing a structure without being affected by the weather.

[0002]

[Prior art]

 Conventionally, when constructing a building, usually an external scaffold is built around the building in advance and a work floor is secured over each layer before proceeding with the work. As this scaffolding, frame scaffolds made by connecting single pipes are often used, and the structure is connected to the building by wall tie to prevent falling.

Although such a scaffold is provided up to the uppermost layer of a building, a cloth plate, that is, a portion serving as a working floor is not installed on the ceiling of the uppermost layer, and the upper portion is open.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional construction method, the site is exposed to rain when it is raining, which may not be appropriate as a work environment for workers, and there is a problem that the construction period is affected by the weather.

Further, it is desirable in terms of quality control that the building is not wetted with rain as much as possible during construction, but there is no special measure in the conventional construction method as described above. On the other hand, it has not been realized to cover the ceiling with a sheet because it is difficult to install and remove and the work is hindered.

The present invention has been made in view of the above-mentioned matters, and the work can be progressed even in the rain, the structure can be completed in a desired construction period, and the quality of the structure can be improved. The technical issue is to provide a roof for buildings that can be installed and removed easily.

[0007]

[Means for Solving the Problems]

 The present invention has the following configuration in order to solve the above technical problems. That is, rails 4 and 5 parallel to the top 3 of the scaffold 2 constructed around the building 1 are provided oppositely, and a structure 6 bridging these rails 4 and 5 is movably mounted on the rail. Then, the upper edge of these structures 6 was covered with the waterproof sheet 7.

[0008]

[Action]

 When constructing a structure, a plurality of movable structures 6 are arranged on the top 3 of the scaffold 2 constructed around the structure 1, and the upper edge of these structures is covered with the waterproof sheet 7. Depending on the position of the structure 6, the building can be completely covered, or an arbitrary area can be freely changed and opened. Therefore, the work can be progressed even in the rain.

In addition, there is no hindrance to the carrying in of the material, and the work environment can be optimized by completely opening it in fine weather. In addition, since it is possible to prevent water from getting wet during construction, it is possible to maintain the quality of the building for many years.

Further, after the building is completed, it can be easily disassembled and relocated.

 Next, an embodiment of the present invention will be described with reference to FIGS. The building 1 is under construction, and the scaffold 2 is built around it. The scaffold 2 is a frame scaffold, and a tower crane C is provided in the vicinity of the scaffold 2 so as to carry in / out the material and move the material for this construction method.

The scaffold 2 is formed in a quadrangle so as to surround the building 1, and rails 4 and 5 are provided on the top 3 of each long side over the entire length. The rails 4 and 5 are installed with the H steel lying sideways. Plural sets of structures 6 bridging the rails 4 and 5 are mounted on the rails 4 and 5.

As shown in FIG. 2, the side surface of the structure 6 in the longitudinal direction has an isosceles triangle shape whose height is about 1/10 of the bottom side, and the upper chord member 6a and the bottom side corresponding to the hypotenuse are formed. The contact point with the corresponding lower chord member 6b has a curvature of about 1 / 4R. The structure 6 is composed of a central portion 6c and two end portions 6d, which can be separated and integrated. The central portion 6c and the two end portions 6d are formed by welding a triangular truss 6e between the upper chord member 6a and the lower chord member 6b, respectively.

The joints between the central portion 6c and the two end portions 6d are reinforced by frames 6f and 6g, respectively, and the frames 6f and 6g are provided with joint plates 6h and 6h. The joint plates 6h and 6h are designed to be superposed on each other, and can be separated and united by passing bolts 6k through bolt holes 6i provided in the joint plates 6h and 6h, respectively.

When the structure 6 is viewed from the side, as shown in FIG. 6, diagonal frames 6j, 6j are extended from the top and a bottom frame 6l is connected to form a triangular shape so that the structure can stand by itself. It has become.

Carts 8 are attached to both ends of the bottom of the structure 6 so that they can be moved on the rail 4. As shown in FIGS. 10 and 11, this dolly portion 8 has roller frames 8a and 8a extending below the bottom frame 6l, and high load rollers 8b and 8b are provided between the roller frames 8a and 8a. It is worn. The guide rollers 8c and 8c are pivotally supported so as to sandwich the rail 4 between the high load rollers 8b and 8b. Further, thrust rollers 8d, 8d for sandwiching the rail 4 in the horizontal direction are provided on the roller frames 8a, 8a. The structure 6 is held by the thrust rollers 8d and 8d so as not to come off the rail 4. A rib 8e is provided in the vicinity of the carriage 8 to reinforce the joint between the upper chord member 6a and the bottom frame 6l.

As shown in FIG. 3, a total of five sets of the structures 6 are arranged on the rail 4, and three sets of auxiliary structures 9 are provided between the structures 6. The auxiliary structure 9 has substantially the same structure as the structure 6, but its side surface is flat as shown in the figure, and cannot be self-supporting.

On the other hand, cross bars 10 and 11 for maintaining a parallel state are provided between each structure 6 and each auxiliary structure 9. The cross bar 10 is provided between each structure 6 and each auxiliary structure 9 or between the auxiliary structures 9 and 9. One end of each of the crossed bars 10a and 10b is connected to the structure 6 respectively. And the auxiliary structure 9 is pivotally supported, and the other ends of the bars 10a and 10b are engaged with the grooves of the sliders 10c and 10c. Here, when the auxiliary structures 9, 9 connected by the crossbar 10 come close to each other, the other ends of the bars 10a, 10b move in the directions of the arrows F in the sliders 10c, 10c, and the auxiliary structures 9, 9 can move while maintaining its parallel state. This function is effective when folding the roof.

As shown in FIG. 7, the crossbar 10 is vertically placed so as to pass through the centers of the structures 6 and the auxiliary structures 9, respectively. In the embodiment shown in FIG. 7, a crossbar 11 is further provided, and two sets are horizontally arranged at the bottom of each structure 6 and each auxiliary structure 9.

In the embodiment shown in FIG. 8, two sets of vertically arranged crossbars 10 are provided in parallel. In any of the embodiments, the structure 6 and the auxiliary structure 9 are moved while maintaining their parallel state. Further, a wire rope W is stretched through each structure 6 and each auxiliary structure 9, and by pulling this, the expansion and contraction of the entire roof can be operated.

The upper edge of the structure 6 and each auxiliary structure 9 is covered with a waterproof sheet 7. As shown in FIG. 1, the waterproof sheet 7 has its end portions located below the both ends of the structure 6 and each of the auxiliary structures 9, and thus has a good protection against rainfall. Is.

By operating the wire rope W by a worker or a winch, the position of the structure 6 can be freely moved to completely cover the building or freely open an arbitrary area. be able to. When completely covered, the inside of the scaffold is completely covered, and the work can proceed even in the rain.

Further, in the opened state as shown in FIG. 1, it is possible to carry in the material, and it is possible to make the work environment optimum by completely opening it in fine weather. Further, after the building is completed, it can be easily disassembled and relocated. According to this construction method, the scaffolding can be installed and removed at the same time, and the structure 6 and the like can be reused, so both the initial cost and the running cost can be kept low. In this way, the inconvenient merit of shortening the construction period can be obtained with a small cost.

Since the structure is separable and connectable, as shown in FIG. 12, by inserting the third structure 20 between the central portion 6c and the two end portions 6d, the entire width can be freely set. Can be changed. For this reason, it is easy to make the width to a predetermined width according to the structure, and the suitability for the site becomes good.

Further, if the carriages 8 attached to both ends of the bottom of the structure 6 can be moved along the longitudinal direction of the bottom frame 6l, it is possible to adjust the width according to the width of the structure. it can. In this case, a roller rail frame 8a, a guide rail into which the roller frame 8a is slidably fitted is installed below the bottom frame 6l, and a stopper for fixing the carriage unit 8 at an arbitrary position is provided to match a desired rail. The position of the carriage unit 8 may be determined so that
