Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a roof material or an outer wall material of a building structure.
[0002]
[Prior art]
The roof of the building structure has a waterproof layer on the rooftop concrete slab or ALC board, or a waterproof sheet is installed on the upper surface of the field board, and a finishing material such as metal is applied on it. To construct. Due to the shortage of people in recent years, it is desired to reduce the number of construction steps. In recent years, it has been desired to improve rooftop design. The same applies to the construction of the outer wall.
[0003]
Under such circumstances, as described in JP-A-5-133070, JP-A-5-209453, JP-A-6-257263, and the like, the resin admixture of inorganic aggregate on the surface of a flexible sheet such as a nonwoven fabric. An outer wall material (outer wall covering material) has been developed in which an object is fixed by spraying or the like, and a decorative layer having a lump of the desired design is provided.
[0004]
Since this outer wall material has flexibility, it can be affixed to the ground so that wallpaper can be affixed, and the workability is good. Moreover, it can be set as the outer wall of various patterns (design) by changing the shape of the lump of the inorganic aggregate and the composition of the color. Furthermore, since the resin mixture of inorganic aggregate is lightweight, the outer wall can be lightened.
[0005]
[Problems to be solved by the invention]
However, since the roof and the outer wall are directly exposed to nature, weather resistance such as rain is required. For this reason, the outer wall material disclosed in each of the above-mentioned publications is subjected to a waterproof treatment on the surface before or after the construction, or the joint material is interposed in the joint.
[0006]
By the way, in the conventional outer wall, rainwater drips down, so waterproof sheets are not installed, and it is only necessary to ensure waterproofness when rainwater drips down. It is only forming.
[0007]
This invention makes it a subject to make waterproofing unnecessary after sticking a roof material or an outer wall material.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has a configuration in which a lump of a required shape obtained by bonding granular aggregates of inorganic aggregates with a resin is arranged and fixed in a pattern of a required design on the entire surface of a waterproof sheet. Nodea Ru.
[0009]
Here, the waterproof sheet refers to a sheet having quality and various functions defined in JIS A 6008 and the like, and does not need to be separately waterproofed.
[0010]
The roof material or outer wall material according to the present invention configured as described above is applied to the surface of a field material, a base material, etc., so that the conventional waterproof sheet tensioning and the finishing material tensioning of the roof or the outer wall are performed simultaneously. Become.
[0011]
When the resin has flexibility , the roof material or the outer wall material can be wound, and the transportability is improved.
[0012]
If the waterproof sheet is mixed with fibers, mesh cloth or non-woven fabric is interposed, or mesh cloth or non-woven fabric is integrally attached to one surface, and dimensional stability is ensured , There is no expansion and contraction of the waterproof sheet over time, and lump separation based on the expansion and contraction of the waterproof sheet can be prevented.
[0013]
Moreover, the waterproof sheet is the case of polyvinyl chloride (PVC) sheet, has good used has an additive of a plasticizer or the like during the molding of the non-volatile. This is because the PVC sheet is generally excellent in dimensional stability, and when an additive such as a plasticizer is volatilized (volatilized), the dimensional stability is further lowered. In order to make it non-volatile, for example, it is obtained by making an additive such as a plasticizer into a powder form.
[0014]
Each roof material or outer wall material described above is attached to the roof base or outer wall base to form the roof or outer wall, but the edge joint portions of the respective waterproof sheets are overlapped and firmly bonded by heat, solvent or adhesive. not good when you fixed.
[0015]
Also, when forming the roof and outer wall, the roof material or outer wall material is cut to the required dimensions, and the cut edge is connected to the edge of another roof material or outer wall material with waterproofing, and the connection it is a good test so as to form a joint by peeling the portion of the lump.
[0016]
In this way, when the waterproof sheet is applied, a gap is formed at the opposite edge of the adjacent waterproof sheet to create a joint, and it is not necessary to fill the joint with the joint material, and it is exposed by lump separation. Since the surface is a waterproof sheet surface, there is no problem.
[0017]
In each of the above inventions, a lump of inorganic aggregate is fixed to a waterproof sheet in advance. After the above waterproof sheets are pasted on a ground surface of a roof or an outer wall, the resin mixture of the above inorganic aggregate is used. the blowing on the waterproof sheet surface, that on the tarpaulin, by fixing by disposing the lump of the required shape to the pattern of the required design, Ri to form a roof or the outer wall, the roof bed or exterior wall base After forming the waterproof coating layer on the surface, spray the resin mixture of the inorganic aggregate on the surface of the waterproof layer, and place the lump of the required shape on the waterproof sheet in the pattern of the required design and fix it by, Ru can form a roof or outer wall.
[0018]
【The invention's effect】
By configuring the present invention as described above, the following effects (1) to (3) are exhibited.
(1) Since the waterproof sheet and the design material are integrated, and the waterproof sheet tensioning work and the finishing material tensioning work can be performed in one time, man-hours can be saved and two functions can be performed in one, reducing costs. Can do.
(2) The roof or outer wall is lightweight and has a low risk of peeling or peeling due to an earthquake or the like due to the stretchability of the waterproof sheet and the binding resin.
(3) Because it is the same construction as the waterproof sheet, it can be easily combined with a non-combustible fireproof board, making it easy to have a fireproof structure.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 and FIG. 2 show an embodiment. On a known waterproof sheet 1 such as vinyl chloride, cinnabar sand, pebbles, ceramic aggregate granules (granulated sugar), etc., acrylic emulsion, vinyl chloride, etc. A rectangular lump (roof piece, length × width × thickness: 35 × 95 × 3 mm) 2 having an arbitrary design bonded with the above resin is shifted half and vertically and fixed. The shape and arrangement of the roof pieces 2 are arbitrary. Further, the width (W) and length (L) of the sheet (rectangle) are also determined appropriately in consideration of manufacturability, transportability, and the like. The joint 4 may leave the surface of the waterproof sheet 1 as it is, but can also be filled with an appropriate joint material. The joint material may be at the time of forming the roof material or at the time of construction.
[0020]
The waterproof sheet 1 is of a required size, as in the prior art, and, as shown in FIG. 3, the tensile resin a is mixed with the molding resin mixture, and the fiber a In addition, as shown in the figure (b), the mesh cloth b is interposed by crimping, and as shown in the figure (c), the mesh cloth b is crimped on one surface. As a result, dimensional stability shall be good. In addition, a powdery plasticizer is used so as not to volatilize after molding.
[0021]
The roof material A is stretched around the field material 3 as shown in FIG. When used as an outer wall material, the roof material A is used as an outer wall material A, and the outer wall material A is stretched on a base material (base material) of the outer wall. As shown in FIGS. 4 (a) and 4 (b), the peripheral edges of the sheets are abutted, and a separate belt-like sheet piece c is attached from above or below, or as shown in FIGS. 4 (c) and (d). In addition, they may be overlapped and pasted. In addition, the sheet piece c part becomes the joint part in the figure (b). In the case of this superposition, it is preferable to form a joint portion 1a where the roof piece 2 is not provided on at least two sides (see FIGS. 5 and 6). If there are joint parts 1a on at least two sides, adjacent sheets can be stacked vertically and horizontally, and if there are joint parts 1a on all four sides, the joint part can be cut in either the width direction or the vertical direction. Two or more sides 1a remain, and adjacent sheets can be stacked.
[0022]
In the embodiment shown in FIG. 5, the sheet 1 is wound as a long object, and a joint portion 1 a having a required width without the roof piece 2 is formed on the front edge and one side edge. The adjacent sheets 1 are stretched by overlapping the joint portions 1a. As shown in FIG. 6, the roof piece 2 may be in a solid state (a state in which the granular material is fixed except for the joint portion 1 a). The joint part 1a can be omitted.
[0023]
In the embodiment shown in FIG. 7, the upper surface of the roof piece 2 is inclined, and the inclination due to the reflected light, for example, a shadow or the like changes due to the inclination.
[0024]
In addition, when the roof piece 2 faces the cutting edge by cutting the roof piece (the lump 2) when the sheet 1 is cut, the joint portion 1a is secured at the cutting edge, or the design surface Therefore, if it is necessary to secure the joint portion, the roof piece 2 can be secured by peeling off the appropriate width and length.
[0025]
In each of the above embodiments, the waterproof sheet 1 to which the roof piece 2 is fixed in advance is attached to the roof or the outer wall base, but only the waterproof sheet 1 is attached to the base and the above-mentioned aggregated granular material is mixed. An object can be sprayed on the surface of the waterproof sheet 1 so that the lump 2 is provided (fixed).
[0026]
Further, instead of the waterproof sheet 1, a waterproof layer is formed on the base by directly spraying or applying a coating material capable of forming a waterproof layer such as urethane, rubber, epoxy, PVC, etc. on the roof or outer wall base. And the said resin mixture is sprayed on the waterproof layer, and the lump 2 can also be provided (adhered).
[0027]
A process for preventing deterioration of the roof piece 2 over time, for example, a weather-resistant coating film can be formed on the entire surface of the roof and outer wall made by the present invention by spraying, coating, or the like.
