Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for constructing a flat plate-like structure such as a balcony or an eave extending from a skeleton by a PC method, and more particularly to a balcony structure for facilitating retrofitting and a method of mounting the balcony. Things.

[0002]

2. Description of the Related Art Conventionally, when a balcony is constructed on a skeleton constructed by the PC method, a method of arranging reinforcing bars in a balcony portion in a continuous protruding manner from the skeleton in advance and placing concrete is used. It was adopted and was done exclusively by construction work on site.

[0003]

Therefore, not only the number of construction days on site is lengthened, but also various types of work such as rebar work, temporary framing work, concrete placing work, plastering, etc. are required, so the arrangement of the craftsman is adjusted. Had a difficult problem that had to be done.

[0004] The present invention has been made in view of the above-mentioned problems, and it is possible to construct a structure such as a balcony or an eaves in a factory and assemble the structure simply by assembling the structure with a frame built on the site. It is an object of the present invention to provide a new balcony structure by the PC method capable of simplifying the work of the above and shortening the construction period, and to propose a method of mounting the balcony.

[0005]

A balcony structure according to the present invention is a balcony structure in which a flat plate-like structure is extended from the wall surface of a building to be constructed by a PC method. The PC slab, which has a predetermined shape and size and has a flat plate shape,
A PC slab structure is formed by arranging a plurality of sheath tubes penetrating and embedding between both end edges of the slab at predetermined intervals, and a male screw is screwed into an inner end of a tightening shaft inserted into the sheath tube. In a balcony having an assembled structure in which a tightening nut is screwed to a tightening screw portion screwed to an outer end portion and tightened at an edge of the PC slab structure, a male screw screwed to an inner end of the tightening shaft is provided. A female screw is screwed and integrated with a plurality of embedded long nuts which are screwed with female screws which are embedded and integrated corresponding to the position where the sheath tube is exposed, which is located at the PC slab structure mounting portion of the wall frame. The gist of the present invention is as follows.

An embedded recess having a bottom fastening step surface having a diameter larger than the outer diameter of the sheath tube may be formed at the end of each sheath tube at the outer edge of the PC slab structure. Further, the intermediate portion of the tightening shaft can be replaced with a wire rope having almost no elongation.

[0007] The method of mounting a balcony according to the present invention is a method for mounting a balcony.
When a plate-like structure is extended from the wall surface of a building to be constructed by the C method, the tightening shaft inserted through the sheath tube is screwed into the embedded long nut embedded in the outer wall frame by the above structure, and the PC slab is used. At the same time as determining the height position of
A tightening nut is screwed into a tightening screw portion appearing at the other end of the C slab, and is firmly tightened to form a single support beam structure.
The gist is to suspend and fix the slab structure with a predetermined supporting force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a new balcony structure by the PC method according to the present invention will be described below with reference to FIGS. FIG. 1 is a longitudinal sectional view of a main part showing a state in which a PC slab 1 constituting a balcony is constructed on an outer wall frame 3 of a building 2. As shown in FIG. It has the shape of a flat plate having a predetermined shape and size.

The PC slab 1 has a structure in which a sheath tube 7 is buried and integrated within a plate thickness over a base end surface 5 and a slab end surface 6, and a plurality of PC tubes are provided at predetermined intervals in the frontage direction. A sheath tube 7 is provided. The end of the sheath tube 7 on the side 6 of the end surface of the slab forms an embedding recess 8 having a bottom fastening step surface having a diameter larger than the outer diameter of the sheath tube 7.

[0010] Further, at the mounting portion of the PC slab 1 of the outer wall frame 3, an embedded long nut 9 is previously arranged and integrated corresponding to a position where the sheath tube 7 is exposed on the surface 5 of the base end edge. . A female screw 10 of the embedded long nut 9 is screwed with a male screw 12 screwed on a base end side of a steel tightening shaft 11, and the tightening shaft 11 is inserted into the sheath tube 7 of the PC slab 1. At the same time, a tightening nut 14 is screwed into the tightening screw portion 13 screwed at the end.
And tightly tightened at the position of the embedded recess 8.

The balcony structure having the above-described structure is such that the PC slab 1 produced in advance in the factory is assembled to the outer wall frame 3 by the tightening shaft 11, and the tightening shaft 11 inserted through the sheath tube 7 is embedded in the outer wall frame. The height position of the PC slab 1 is determined by being screwed into the long nut 9, and at the same time, the tightening nut 1 is inserted into the tightening screw portion 13 that appears in the recess 8.
When the PC slab 1 is screwed up and firmly tightened, the PC slab 1 forms a one-sided support beam structure, and is constructed with a predetermined supporting force.

As described above, the tension required for supporting the PC slab 1 by the cantilever structure is applied to the tightening shaft 11, and the intermediate portion of the tightening shaft 11 is connected to a wire rope having almost no elongation. Even in the case of an alternative structure, it can be implemented in the same manner as the above-described structure.

[0013]

As described above, according to the structure of the balcony according to the present invention and the method of mounting the balcony, the structure of the balcony in which the flat plate-like structure is extended from the wall surface of the building constructed by the PC method. In the above, a PC slab structure in which a plurality of sheath tubes are arranged at predetermined intervals in the frontage direction of a flat-plate PC slab having a predetermined shape and size is prepared, and a tightening shaft inserted through the sheath tubes is attached to the outer wall frame. The height position of the PC slab is determined by screwing it into the buried long nut, and at the same time, the tightening nut is screwed into the tightening screw portion that appears at the other edge of the PC slab, and then firmly tightened to provide a single-support beam structure. Since the PC slab structure is suspended and fixed with a predetermined supporting force, a PC slab structure such as a balcony or an eave can be factory-produced in advance.

Therefore, it is possible to construct the PC slab structure simply by assembling it on the building constructed at the site.
It has features such as simplification of work on site and shortening of the construction period, and the effect obtained by implementing the present invention is extremely large.
