[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a prefabricated roof structure, and more particularly to a prefabricated roof structure capable of changing the roof in a short period of time.

[0002]

[Prior art]

 Conventionally, when reroofing a roof, it has been necessary to manually carry out the steps of first removing the roof part, then erecting the pillars, then attaching the beams and girders and then attaching the roof boards. It was

For this reason, it takes a lot of labor and time to change the roof. Also, since it requires skill, only a carpenter with a long season could be performed.

Further, since the conventional roof has a triangular shape, the space between the roof plate and the floor becomes narrower toward the outside. Therefore, it could not be used as a space for people to live in, and could only be used as a storage position.

Further, since the entire roof plate is flat and flat, a wind pressure from the side is directly applied, and the vertical pillar receives the wind pressure, so that the resistance force to the side wind is weak. In addition, there was a problem in terms of structural earthquake resistance.

[0006]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and it is possible to construct each component by separately forming them in advance and simply assembling each component in the field. None, so that roof reshuffling work can be done without much effort within a short period of time, and the vertical cross-section of the roof body has an arched shape that raises upwards, so that The purpose of the present invention is to provide a prefabricated roof structure that expands the space, enhances the resistance force against the wind pressure from the side, and further improves the earthquake resistance.

[0007]

[Means for Solving the Problems]

 Thus, the gist of the present invention is a pair of left and right curved plates constituting a roof main body, which are curved and provided with a heat insulating layer and a ventilation layer inside and a vent hole communicating with the ventilation layer at the joint, A semi-circular side wall plate with a heat insulating layer and a ventilation layer inside, which is attached to both ends of the curved plate that constitutes the roof body, and a width corresponding to the area of the curved plate that constitutes the roof body. In addition, the prefabricated roof structure consists of a floorboard that is installed on the frame of an existing house by providing entrances and exits at appropriate locations, and joining them by appropriate means.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is an overall perspective view before assembly, FIG. 2 is a front view in an assembled state, FIG. 3 is a side view in an assembled state, FIG. 4 is a plan view in an assembled state, and FIG. 5 is I- in FIG. 4 is a sectional view taken along line II-II in FIG. 4, FIG. 7 is a sectional view taken along line III-III in FIG. 4, FIG. 8 is an enlarged view of portion A in FIG. 6, and FIG. 9 is B in FIG. FIG. 10 is an enlarged view of a portion, and FIG. 10 is an enlarged view of portion C in FIG.

In the figure, reference numerals 1 and 1 ′ are a pair of left and right curved plates that form a roof body. The curved plates 1 and 1 ′ each have a beam 2 curved in an arc shape, three plywoods 3, 4 and 5 stacked on the beam 2 at a required interval, and an inner plywood 3 and an intermediate plywood 3. The heat insulating layer 6 formed by leaving a ventilation layer between the plywood 4, the ventilation layers 7, 8 formed with a gap between the three plywoods 3, 4, 5 and the upper surface of the outer plywood 5 are covered. It comprises an iron plate 9 and a ventilation port 10 provided at the joint and communicating with the ventilation layers 7 and 8. The curved plates 1 and 1'join the seams by an appropriate means such as an adhesive. Reference numeral 11 denotes a cover support frame which is provided upright on the outer periphery of the vent hole 10, and 12 denotes a cover which is attached above the cover support frame 11 by a suitable means such as a screw 13.

Further, in the present embodiment, the window 14 is provided on the one curved plate 1 ′. The window 14 may be provided on both the curved plates 1 and 1 '. Further, the window 14 may be a different type, or may be of another type.

Reference numerals 15 and 15 ′ are semicircular side wall plates to be attached to both ends of the curved plates 1 and 1 ′. The side wall plates 15 and 15 ′ are two plywood plates 16 and 17, respectively, which are superposed at a required interval, an outer wall plate 18 is superposed on the outer side of an outer plywood plate 17 and are at a predetermined interval, and the above-mentioned two sheets. The heat insulating layer 19 formed by leaving a ventilation layer between the plywoods 16 and 17, and the ventilation layers 20 and 21 formed with a gap between the two plywoods 16 and 17 and a gap between the plywood 17 and the outer wall plate 18. It will be.

The side wall plates 15 and 15 are joined at their outer edges to the curved plates 1 and 1'and a floor plate described later by appropriate means. Further, in this embodiment, windows 22 are provided on both of the side wall plates 15 and 15 '.

Reference numeral 23 is a floor plate attached to the frame of the existing house. The floor plate 23 is formed to have an area corresponding to the area of the curved plates 1 and 1 ', and an entrance 24 is provided at an appropriate portion. The floor board 23 is composed of a floor joist 25 and a plywood 26. An outer wall plate 27 is stretched on the outer circumference.

Further, 28 and 29 are side joists, 30 is a lower frame formed on the peripheral edge of the floor plate 23, 31 is a draining plate, 33 is the eaves girder of an existing house, 34 is between the eaves girder 33 and the floor plate 23. The head splicing, 35 is a repair cut edge, 36 is caulking material, and 37 is an existing house.

[Effect of device]

 The present invention is configured as described above, and the pair of left and right curved plates constituting the roof main body, the side wall plates attached to both ends of these curved plates, and the floor plate attached to the frame of the existing house are separately separated in advance. Since it can be built by simply assembling each of these components integrally at the site, it is possible to reroof the roof in a short period of time without much effort. It is possible. In addition, a new roof can be easily constructed without requiring the skill required for conventional carpentry work.

In addition, since the roof body of the present invention has an arch-shaped vertical cross-section, the space that can be used can be greatly expanded compared to the conventional triangular roof, and a space for people to live in. It is also possible to use as. In addition, since the roof body has a curved surface, the resistance to cross winds is significantly increased and the earthquake resistance is also improved.

Furthermore, since the pair of curved plates and the side wall plates each have a double ventilation layer formed therein to allow the air to circulate through the ventilation holes, it prevents moisture inside the roof and keeps it warm. The effect can be further improved.
