A pair of left and right reinforced concrete side walls 2, 2 are erected on the upper side so as to extend in parallel with a space therebetween.

Next, as shown in FIG.
A bag member 3 is erected between the upper edges of the bag member 3 and an air compressor (not shown) presses air into the bag member 3 to form an arched mold surface 3a on the upper surface of the bag member 3.

Then, a reinforcing steel mesh is arranged along the mold surface 3a, and fresh concrete is sprayed so as to bury the reinforcing steel mesh, so that the upper edges of the left and right side walls 2, 2 are connected as shown in FIG. A roof 5a is formed.

[0013] peeling-off this way, the local roof 5a is formed, the bag member 3 from deflating not be in the roof 5a
Since it is separated, it is easily moved to a portion adjacent to the roof 5a along a rail described later . Then, the bag member 3 is expanded again, and a reinforced concrete roof is formed on the arched mold surface formed on the upper surface of the bag member 3 in the same procedure as described above. The roof 5 is completed as shown. A plurality of openings for dropping industrial waste are formed in the roof 5 and a watertight opening / closing lid 6 is attached.

An unillustrated reinforced concrete end wall is formed so as to connect the side wall 2 and the end of the roof 5. The internal ground of the building completed in this way is excavated to form a recess 4, and the surface of the recess 4 is waterproofed by laying a plastic sheet or the like.

In the above-described construction method for a building with an arched roof according to the present embodiment, the bag member 3 spanned between the upper edges of the left and right side walls 2, 2 is expanded on the upper surface of the bag member 3. At least a part of the arch-shaped mold surface 3a is formed, and the fresh concrete is sprayed so as to bury the reinforced mesh arranged along the same mold surface 3a, and the solidification thereof causes the arch-shaped reinforced concrete roof 5a to be used as a scaffold. , And can be formed simply without requiring.

[0016] Then, when the construction as shown in FIG. 6 by connecting a building with a plurality of the same shape and size in parallel form, repeated use of the bag member 3 is capable of ing.

Further, the method of forming the adjacent roof by moving the bag member 3 every time the local roof 5a is formed is advantageous in the case of constructing a single building, and is small in scale. Since the bag member 3 can be repeatedly used by moving on a rail (not shown) along the upper edges of the left and right side walls 2 and 2, the construction cost of the building can be significantly reduced.

When storing industrial wastes and the like in the above-mentioned building, as shown in FIG.
Then, the opening / closing lid 6 is opened, and as shown in FIG. 5, the industrial waste is charged into the opening by the dump truck 7. Then, in the building, the unmanned bulldozer 8 carries out the work. The roof 5
A surveillance camera 9 and a projector 10 are mounted on the inner surface of the camera.

When the buildings 5 are to be connected, as shown in FIG. 7, a reinforced concrete roof 11 is buried with a reinforcing bar network 11, and a reinforcing bar extending between the adjacent roofs 5, 5. 12 is buried, and steel wire (tendon) is used to make the roof 5 made of prestressed concrete
13 is also given.

Regarding the side wall 2 made of reinforced concrete,
In addition to the reinforcement bar 14 that straddles the roof 5, an earth anchor wire 15 is provided during construction to prevent the bag member 3 from falling inward when compressed air is pressed into the bag member 3. .

[0021]

As described in detail above, the following effects can be obtained by the method of constructing a building with an arched roof according to the present invention. (1) Due to the expansion of the bag member bridged between the upper edges of the left and right side walls, an arch-shaped mold surface for a local roof is formed on the upper surface of the bag member, and the same shape surface is formed. The fresh concrete is sprayed so as to bury the reinforcing steel mesh arranged along the side, and the solidification thereof allows the arched reinforced concrete roof to be easily formed without requiring a scaffold or the like. (2) Since a bag member for sequentially forming a local roof is used between the upper edges of the left and right side walls, a small-sized bag member is moved on a rail along the upper edges of the left and right side walls. In this way, it can be used repeatedly, which can significantly reduce the construction costs of the building. Soshi
Since the bag member is a lightweight structure,
There is an advantage that movement can be performed simply by simply sliding. (3) The above-mentioned bag members can be used repeatedly even when constructing many buildings of the same shape and size.
