In forming such a continuous bag body 5, as shown in FIG. 2, a lateral film sheet 4 having a predetermined height is laterally inserted into a gap between a wide surface film sheet 2 and a rear film sheet 3. By arranging and joining the upper and lower edges of the side film sheet 4 to the top film sheet 2 and the back film sheet 3, respectively, the continuous bag body 5 can be manufactured with a simple structure.

In FIG. 3 and FIG. 4, reference numeral 6 denotes a resin filling port, which is attached to substantially the center of the surface film sheet 2 or the back film sheet 3 of each of the flexible bags 1. Therefore,

By combining these materials, a particularly excellent synergistic effect is obtained. Is a non-combustible film material that can exhibit

As the granular resin foam 8 used in the above embodiment, any of a thermoplastic resin and a thermosetting resin can be used, but a thermoplastic resin is preferable. Examples of this thermoplastic resin include polyethylene,
Examples include polypropylene, polyvinyl chloride, polyvinylidene chloride, and cellulosic resins.

The density of these granular resin foams 8 is 2
It is preferably 0 to 100 kg / m ³ , and the particle size is preferably 0.5 to 5 mm. That is, a relatively hard and lightweight synthetic resin foam is desirable. The above density is JISK7
It is a value measured in accordance with 222. Further, the thickness of the independent cell formed by filling each flexible bag 1 with the granular resin foam 8 varies depending on the use of the building material, but the thickness is about 50 to 300 mm. preferable.

In the building material according to the present invention, when the continuous bag 5 is in a state before forming the independent cells, a part of the flexible bag 1 is cut off in advance, and thereafter the continuous bag 5 is cut. The flexible bag 1 is filled with the granular resin foam 8 to produce a building material having an opening 9 as shown in FIG.

In the building material according to the present invention, the opening 9 of the building can be formed in this portion. A window sash, a door sash, or the like is attached to the opening 9 and can be used as an opening window or an entrance.

The construction method according to the present invention will be described below. That is, first, in forming the continuous bag body 5, after the flexible bag body 1 is formed by the top membrane sheet 2, the back membrane sheet 3 and the four side membrane sheets 4 as already described with reference to FIG. Thus, a large number of flexible bags 1 can be connected left and right in a planar manner. Alternatively, as shown in FIG. 2, a plurality of side film sheets 4 are arranged in the left and right direction and joined between a wide surface film sheet 2 and a back film sheet 3 arranged in parallel with a predetermined gap therebetween. It is also possible to divide the space formed between the front and back membrane sheets 2 and 3.

Next, the continuous bag body 5 constructed as described above is carried into the site and attached to a part of the building, for example, a structural column or a structural beam, as shown in FIGS. 3 and 4. A granular resin foam 8 is filled from the resin filling port 6 provided in the flexible bag 1, shaped and standardized to form an independent cell with the flexible bag 1 as a unit. .

In filling the flexible bag 1 with the granular resin foam 8, for example, as shown in FIG. 3, a hose 12 is pulled from a plant (not shown) to the flexible bag 1, and By inserting the nozzle 12 a at the tip of the hose 12 into the filling port 6, the granular resin foam 8 can be sequentially injected and filled into each flexible bag 1. Then, a lid 6a is placed in the filling port 6.
To seal the granular resin foam 8. The filled granular resin foam 8 can form an independent cell together with each flexible bag 1.

As described above, all the flexible bags 1 of the continuous bag 5 are filled with the granular resin foam 8 to form independent cells, and each independent cell is continuously formed into a fixed form. The building material can be formed by making the shape. As described above, the continuous bag body 5 attached to a building is, for example, as shown in FIG.
6 (A) is used as a non-bearing wall 17 by attaching to the dome-shaped roof 13 or the structural column 10 and the structural beam 11 of the building 14 or a curved sloped roof of the building 16 shown in FIG. 6 (B). It can be used as the non-bearing wall 17 by being attached to the structural beam 15, the structural column 10, the structural beam 11, and the like.

The building materials according to the present invention can be used as non-bearing wall materials for buildings and structures such as office buildings, warehouses, houses, and the like.
Roofing materials (especially dome-shaped and quadratic curved roofs can be manufactured)
Can be used for a wide range of applications. Further, the building material according to the present invention is effective as a building material that is lightweight and has excellent heat insulation and sound insulation properties. The structural body as a building is borne by a separate structural member such as a steel frame, concrete, or wooden structure. In particular, when the building material according to the present invention is used for a roofing material, a large building space that is lightweight and has no beams can be constructed. The roof span that can be constructed without using beams is about 7 to 30 m.

[0028]

The construction material and the method for constructing a building according to the present invention have the above-mentioned structure and operation, and therefore have the following great effects.

(1) Since the continuous bag of the building material according to the present invention or the film material forming the continuous bag is light and not bulky, a large part of the building such as the entire building or the roof can be integrally formed as a part. Possible, can be transported at once,
Distribution costs can be significantly reduced. (2) A continuous bag body is formed by combining a large number of bag bodies in a plane in accordance with a predesigned shape, and a granular resin foam is injected into each bag body at a building site, whereby each bag body is formed. An independent cell is formed while the bag body is inflated, whereby a building having a desired plane, curved surface, or the like can be freely configured.

(3) Therefore, the construction is extremely simple,
Labor saving in construction work is possible, and construction costs can be significantly reduced. (4) Each bag is filled with a granular resin foam, and the planar body with continuous independent cells is lightweight. Therefore, when used for roofing materials or non-bearing walls of buildings, the burden on structural members is reduced. The structure can be reduced, and the structural strength can be reduced as compared with the case where a member such as a conventional concrete plate is used for a roof material or a non-bearing wall. In addition, the resin foam and the membrane material can exhibit the required heat insulating properties and sound insulation properties as building materials.

(5) Since a large number of independent bags are continuous in a plane, even if the structure is large, each bag is sequentially filled with a granular resin foam, so that the entire structure can be formed. It can be evenly filled to form a uniform building material. (6) When this building material is used as a roof material, a large space without beams can be constructed.

(7) By removing the bag corresponding to the opening at a predetermined position in the continuous bag in advance, the granular resin is attached after the continuous bag is attached to a building. When the foam is filled in each bag, an opening serving as a window, an entrance or the like can be automatically formed. (8) Unlike a building having a conventional air film structure, a building made of the building material according to the present invention does not need to constantly send air into the building, and thus is suitable for general houses and the like.
