BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for forming a water gradient by inclining a roof, and more particularly to a water gradient construction method suitable for flat roofs such as roof slabs made of lightweight cellular concrete panels.

0002

[Prior Art] Conventionally, a roof made of lightweight aerated concrete panels (hereinafter referred to as ALC panels) installed on a roof slab has been constructed by first forming a slope that gradually increases in height, as shown in FIGS. 5 and 6. Bolt 3 to beam bundle 301 to land beam 1
A beam material 303 made of angle iron or the like is fixed to a slope beam bundle 301 fixed to the land beam 1 in large numbers at a predetermined pitch according to 02.
By connecting these with bolts 304, a slope beam 300 for water slope was formed. And this slope beam 3
A sloped roof slab 200 is formed by fixing the ALC panel 20 on top of the roof slab 200, and after laying particle board 50, asphalt roofing 51, etc. on the entire surface of the roof slab 200, roofing with tiles 6 etc. A method was adopted to form a roof with a slope.

[Problems to be Solved by the Invention] However, in this conventional method, the slope beam must first be assembled on a narrow land beam, and for construction safety reasons, it is necessary to install horizontal nets, etc. There were problems in that construction efficiency was poor and it was difficult to save labor.

[0004] Furthermore, when constructing a roof slab, it is not possible to temporarily place a large number of ALC panels on a sloped beam, and the panel must be received and installed one by one, which takes extra time and effort. there were. In addition, there was a problem that during work, there was a sloped beam on top of the land beam, which made the footing difficult, making it very dangerous and reducing work efficiency.

[0005] Furthermore, slope beams can only be constructed on land beams and their placement is limited, so even if there is a penthouse, the roof shape is generally a gable type or one-sided type, and the roof shape is not aligned. If you want to use a ridge type, etc., change the beam construction method and AL
There was a problem in that the C panel also needed to be processed accordingly.

[0006] Furthermore, since the structure does not create a space between the roof slab and the roof, it is not possible to install insulation material between the roof slab and the roof, and flat roof type roofs with a small water slope do not have insulation. There was a problem that the sex deteriorated.

[0007] The present invention solves the problems of the conventional methods as described above, allows installation of roof slabs using ALC panels and roofing work safely, and also saves labor and improves work efficiency. To provide a water slope construction method for a roof, which allows the roof shape to be arbitrarily set, and also enables the installation of a heat insulating material between the roof and the roof slab.

[0008]

[Means for Solving the Problems] As a means for achieving the above-mentioned object, in the water slope construction method for a roof of the present invention, a roof having a water slope is provided on a roof slab made of lightweight aerated concrete panels. Lightweight aerated concrete panels are fixed on the land beams to form a horizontal roof slab, slope beams are fixed at a specified pitch to the top surface of the roof slab formed on the land beams, and slope beams are fixed to the top surface of the roof slab. A method was adopted in which the roof base material was fixed and the roof was placed on the roof base material that was fixed on the sloped beams.

[0009]

[Operation] In the roof water slope construction method of the present invention, as mentioned above, the ALC panels are fixed to the land beams to form the roof slab, so the roof slabs are arranged horizontally, so first, a plurality of ALC panels After forming a roof slab by temporarily placing it on the land beams at key points, a large number of ALC panels are temporarily placed on this slab,
The ALC panel on this roof slab is used to extend the roof slab. In this case, the roof slab that has already been laid serves as a horizontal and wide footing, and there are no protruding parts such as slope beams on the land beams, so the work can be carried out safely and efficiently. Further, the sloped beams may be fixed at a predetermined pitch on the upper surface of a horizontally formed roof slab, and the roof is covered after a base material such as particle board or asphalt roofing is attached to the sloped beams. In this case, since a space is formed by the sloped beam between the roof base material and the roof slab, a heat insulating material can be laid in this space. Also,
Various roof shapes can be formed depending on the arrangement of the sloped beams.

Fig. 1 is a sectional view showing the roof structure according to the embodiment of the present invention from the side of the slope beam, Fig. 2 is a perspective view showing the installed state of the slope beam, and Fig. 3 shows the roof structure of the above example from the front side of the slope beam. The cross-sectional view shown in FIG. 4 is an explanatory diagram showing the arrangement of sloped beams that form the roof of the penthouse into a hipped shape. The roof structure A of this embodiment mainly includes a land beam 1, a roof slab 2, a slope beam 3, a heat insulating material 4, a roof base material 5, and tiles 6.

The land beam 1 serves as an attachment beam for the roof slab 2, and is formed by horizontally arranging a plurality of H-beams, and in the embodiment, has a penthouse 10 shown in FIG. 4 on one end side. ing.

[0012] The roof slab 2 is formed by using ALC panels 20 in a predetermined shape and extending them horizontally. 21 in the figure is the ALC panel 20
This is a fixing fitting that fixes the joint reinforcing bars 22 passed through the joints to the land beam 1.

The sloped beam 3 forms a flat roof with a slightly sloped roof, and as shown in FIG. Horizontal flanges 30, 30 are provided on the sides. Further, a slope of 1/200 is provided in the longitudinal direction. In the figure, 31 is a mounting surface of the roof base material 5 provided on the slope beam 3, and 32 is a fixing screw.

The roof base material 5 is composed of a particle board 50 forming a field and an asphalt roofing 51 forming a waterproof layer.
1 to a particle board 50 with staples or nails. In the figure, 52 is a tile beam.

Next, a method for forming the roof will be explained. First, after forming the land beam 1, ALC panels 20 are temporarily placed and extended on the land beam 1 at important points, and the remaining ALC panels 20 are placed on top of the land beam 1 and the extended ALC panels 20, using the land beam 1 and the extended ALC panels 20 as footholds. At the same time, the temporarily placed ALC panels 20 are all installed on other land beams 1. Then, joint reinforcing bars 2 are placed at the horizontal joints between the laid ALC panels 20.
2, and connect this joint reinforcing bar 22 to the upper flange 1 of the land beam 1.
The ALC panel 20 is fixed to the land beam 1 by inserting it into a through hole of a fixing fitting 21 fitted and fixed to the land beam 1, thereby forming a horizontally arranged roof slab 2. Next, the slope beam 3 is taken in and temporarily placed on the roof slab 2 formed on the land beam 1, and on the top surface of this roof slab 2, as shown in FIGS. 3 and 4, one gable side The sloped beams 3 are arranged side by side at a predetermined pitch from one side perpendicular to the gable side, with the mounting surface 31 facing upward, and the parts where the sloped beams 3 intersect at right angles are cut to form a hipped ridge 34. form. After fixing the slope beam 3 to the roof slab 2 with screws 32, a heat insulating material 4 is spread over the entire space 33 formed between the slope beams 3. Then, the particle board 50 is placed on the mounting surface 31 of the slope beam 3 and fixed with adhesive, screws, fasteners, etc. to form a field. After forming a waterproof layer by laying asphalt roofing 51 on top of this and fixing it with staples, a roof structure A having a water slope can be formed by providing tile beams 52 at a predetermined pitch and covering with tiles 6.

As explained above, according to this embodiment, the ALC panel 20 forming the roof slab 2 is connected to the land beam 1.
Since it is placed horizontally on top, there is no need to limit the shape of the roof, change the position of the landing beam, or process the ALC panel 20. In addition, ALC panel 20 placed on top of the land beam 1 or at the beginning.
The top surface can be used as a temporary storage area for other ALC panels 20, and other ALC panels 20 can be extended using the ALC panel 20 placed on the land beam 1 or this land beam 1 as a foothold. , it is possible to save labor and increase work efficiency, and to perform work safely.

[0017] Furthermore, the slope beams 3 are simply fixed on the roof slab 2 at a predetermined pitch by using the horizontally installed roof slab 2 as a temporary storage area or scaffolding for assembly, regardless of the position of the land beam. Since a predetermined water gradient is formed, anyone can assemble it without any special skills. Also,
Similarly to the above, it is possible to save labor and increase work efficiency, and also to perform safe work. Further, the land beam 1 does not require any hole machining for attaching the slope beam 3, and the machining of the land beam 1 can be simplified. The slope beam 3 can be arranged to match a predetermined roof shape and simply cut at the ridge position to form a predetermined roof shape regardless of the position of the land beam. Further, since the slope beam 3 is formed by bending a thin galvanized iron plate, it can be manufactured at low cost and can be easily transported, processed, and installed.

Furthermore, since a space 33 is formed between the roof base material 5 and the roof slab 2 by the slope beam 3, the heat insulating material 4 is laid in this space 33 so that the roof slab 2 is It can provide insulation and prevent condensation.

Although the embodiments of the present invention have been described above,
The specific configuration of the present invention is not limited to this embodiment, and the present invention includes any design changes that do not depart from the gist of the present invention. For example, in the embodiment, Luliang 1
Although the above ALC panel 20 is fixed by inserting the joint reinforcing bars 22 into the through holes of the fixing metal fittings 21 that are fitted and fixed to the upper flange 11 of the land beam 1, the fixing metal fittings 21 are not limited to this.
The method of fixing to the land beam 1 and the method of fixing the joint reinforcing bars 22 can be set arbitrarily.

Further, in the embodiment, the slope beam 3 is formed by bending a thin galvanized iron plate, but the slope beam 3 is not limited to this, and the slope beam 3 can be formed by welding or by bolting steel plates together. It can be made adjustable, and the structure, material, etc. can be set arbitrarily.

Further, in the embodiment, the roof shape is described as a hipped type having the penthouse 10, but the roof shape is not limited to this, and the roof shape can be arbitrarily set such as a gable type or a one-sided type.

[0022]

[Effects of the Invention] As explained above, in the roof water slope construction method of the present invention, since the land beam is simply used to place the roof slab, there is no need to drill holes for installing the slope beam. The processing of land beams can be simplified.

Furthermore, since the ALC panels forming the roof slab are placed horizontally on the land beams, there is no need to limit the shape of the roof, change the position of the land beams, or process the ALC panels. In addition, the AL that was originally extended on the land bridge
The upper surface of the C panel can be used as a temporary storage area for other ALC panels, and a roof slab can be formed using this ALC panel as a scaffold. Furthermore, it is possible to save labor and improve work efficiency, and to perform work safely.

[0024] In addition, slope beams require special techniques because a specified water slope can be formed simply by fixing them at a specified pitch to the top surface of a horizontally installed roof slab regardless of the position of the land beam. Anyone can assemble it without having to do anything. In addition, it is possible to save labor and increase work efficiency, and to perform work safely.

[0025] Moreover, the slope beam can be arranged to match a predetermined roof shape and simply cut at the intersecting ridge positions to form a predetermined roof shape regardless of the position of the land beam.

[0026] Furthermore, a space is formed between the roof base material and the roof slab by a sloped beam, and a heat insulating material is placed in this space to insulate the roof slab and prevent dew condensation. Effects such as being able to do this can be obtained.
