Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention mainly relates to a roof member installed in a place requiring a long span, such as a factory, warehouse, or gymnasium, and a method for constructing the roof member.

``Prior art'' Conventionally, when constructing a large roof using the dry method, steel plates, corrugated slate panels, etc. were used, and PC (precast) concrete was placed on H-beams placed at intervals of several meters. Place it and fix it directly with a bolt.

At this time, it was necessary to overlap the planks both vertically and horizontally to protect them from the rain before securing them to the base material. Therefore, a board larger than the total area of the roof was required, and construction was also relatively troublesome. Furthermore, the heads of the bolts used for fixing were left exposed.

[Problem to be solved by the invention] When constructing a roof by stacking iron plates, corrugated slate plates, etc. vertically and horizontally using the conventional dry method, the thickness of the plates is thin, so there is room for improvement in aesthetics, solidity, and heat insulation. Ta.

Additionally, since the head of the bolt is exposed, the surface becomes dirty due to rust, etc., and there are problems with aesthetics, waterproofness, and durability.

Furthermore, since each board is stacked on top of each other, it has been pointed out that there are shortcomings in terms of workability and economy.

A first object of the present invention is to provide a roofing board material that does not expose the heads of fixing bolts to the surface after construction and is excellent in aesthetics, waterproofness, and durability.

A second object of the present invention is to provide a roofing board material that is lightweight and has further improved aesthetics, solidity, heat insulation, waterproofness, and workability by eliminating unnecessary overlapping parts, and a method for installing the same. be.

"Means for Solving the Problem" The invention described in claim (1) is a rectangular concave ceramic molded roof member with a waterproof sheet pasted on the surface, and an overhang of the waterproof sheet on one short side. The invention according to claim (2), characterized in that the object of item 1 is achieved by having a portion, is the roof sheet material according to claim (1), wherein a hollow hole is provided inside the roof sheet material along the longitudinal direction, and the roof sheet material is The invention according to claim (3), characterized in that the second object is achieved by reducing the weight, is defined in claim fl) or (2).
When installing roofing sheets on a structure, they are installed with gaps in both the vertical and horizontal directions, and after filling these gaps with sealant, the gaps in the short sides are covered with the protruding part of the waterproof sheet, and the gaps in the long sides are The second objective is achieved by covering the gap with a waterproof cap to create a waterproof structure.

[Example J Fig. 1 shows an end face of a roofing sheet material according to a first embodiment of the present invention, and Fig. 2 is a perspective view thereof.

The standard size of the roof board material 10 is, for example, a width of 60C.
m, length 3m, thickness of thin part 1°5cm, height 10m
cm size is used. Note that this size can be appropriately changed in design depending on the size of the building and the like.

This roof plate material 10 is a rectangular concave ceramic molded roof member, and has thick portions 12 on both sides when viewed from the transverse direction, thereby ensuring strength. On the other hand, the roof board material 10 is provided with hollow holes 18 and thin wall portions 14 along the longitudinal direction in order to reduce the weight of the board material and improve workability.

A waterproof sheet 16 is pasted on this surface. The waterproof sheet 16 has a protruding portion 16-2 on one short side.
Or is provided.

The roofing board material 10 is formed by extrusion molding using a cement raw material as a main ingredient, and is manufactured by steam curing or autoclave curing.

With this type of roofing material, it is especially important to ensure that each of the roofing boards is properly sealed and connected since a large number of roofing boards are placed side by side.

FIG. 3 is a side sectional view showing connections on the long sides. That is,
On the long sides, the thick parts 12 are arranged in correspondence with each other with a slight interval, and a cap 20 is set on the upper part to connect them.

To install this roof board material 10, first, a rafter structure 60 shown in FIG. 5 or a purlin structure 70 shown in FIG. Place the outer lower end of the thick part 12 of the roof board material IO,
Tightening is performed by fixing with a bolt 30 using the washer 28.

The rafter 24 or the fixing piece 26 is a beam 2 made of H-shaped steel.
Adhesively fix it directly to 2 by welding.

The roof board material 10 is attached to the beam 22 via the cushion material 32,
The lower end of the outer side of the thick part is placed on the rafter 24 or the fixing piece 26. Cushion material 3 is also placed between the outer lower end of the thick wall part and the rafter 24 or the fixing piece 26.
Insert 2.

Compatible Roof Materials] The space formed by the 0110-2 and the rafters 24 or the fixing pieces 26 is filled with a back-up material 34 (shown by dotted lines in the drawing) mainly made of foamed resin, etc., and a sealing material is placed on top of it. Construct material 38. Then, the waterproof cap 20 is used to cover the thick part inner side 12-2 to the thick part inner side 12-3. The waterproof cap 20 is made of a waterproof material such as stainless steel or plastic, and is elastically attached to the cap 20 due to the elasticity of this material. Moreover, it is also possible to directly adhere a waterproof sheet to the roof board material 10 instead of these materials.

FIG. 4 is a sectional view of the short side. To connect the short sides of the roof panels 10, a slight gap 40 (for example, 5 to 20 mm) is provided when fixing them to the beam 22, and this gap is filled with back-up material 36 (indicated by dotted lines in the drawing). After that, a sealant 38 is applied. The protruding part 16-2 at one end of the waterproof sheet 16 at the connection part is welded at part A to the opposing roof board lO through the sealing material 38 during construction. This protruding portion 16-2 is constructed so as to face downward with respect to the water gradient, and its length is, for example, about 40 to 100 mm. The waterproof sheet 16 may be a general-purpose one. By doing so, it is possible to achieve double waterproofing using the sealing material 38 and the waterproof sheet 16-2.

FIG. 5 is a partial cross-sectional view showing a partially cut state in which the roof board material 10 is installed in the case of the rafter structure 60.

FIG. 6 is a partial cross-sectional view showing a partially cut state in which the roof board material 10 is installed in the case of the main building structure 70.

As is clear from these figures, each roof sheet material 10 is fixed with bolts 30 at six locations in total, including the four corners and the middle portion in the longitudinal direction. This fixing is performed via the washer 28 as described above, and by fixing each corner of the four roof panel materials 1O, the washer 28 presses each roof panel material 10.

The fixing bolt 30 uses, for example, a self-drilling screw.

A bond breaker 4 is inserted so as to cover the head of this bolt 30.
4 are installed along the length direction of the roof board material 10. Then, a sealing material 38 is applied to the upper surface. If the sealing material 38 is bonded on two sides, the durability will be maintained, but if it is bonded on three sides, the durability will deteriorate. Therefore, in this embodiment, a bond breaker 44 is installed so that both ends are bonded to the roof board material 10 and the lower part (bottom) is separated so as not to come into contact.

The bond breaker 44 is made of polyethylene resin, for example.

Since the longitudinal connection part is covered with waterproof cab 2o,
It has a double waterproof structure in both the short and long directions.

Since the waterproof sheet 16 and the waterproof cab 2o can be made in any color, it is possible to further enhance the sense of solidity and aesthetic appearance.

The embodiments described above are illustrative, and the present invention includes:
The invention is not limited to this example.

"Effects of the Invention J As described above, according to the inventions described in claims (1) to (3), since double waterproofing is applied, safety against rain cover can be increased, and a roof with a flat slope can be constructed. It becomes easier to form.

Since the head of the bolt is not exposed, dirt due to rust etc.
It can prevent construction deterioration and improve aesthetics and durability.

Furthermore, since there is no need to partially overlap the roofing sheets during construction, the total area of the roofing sheets can be reduced.

Since the roofing sheet material according to claims (1) and (21) has a waterproof sheet attached in advance, the number of construction steps at a high-altitude site can be reduced, and work efficiency and construction safety can be significantly improved.

In the roof board material of claim (2), since the hollow hole is provided inside, the roof board material can be further reduced in weight.
