ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a stacked structure used as a structure for, e.g., storing water in the underground.
2. Description of the Related Art
There is known a conventional structure for storing water in the underground as disclosed in, e.g., Japanese Unexamined Patent Publication No. 8-184080. The disclosed structure is constructed by excavating in the ground, forming a hollowed portion surrounded by a water-proof layer and a water-proof-layer protective material in the underground, installing a number of perforated pipes within the hollowed portion to fit with one another in close contact relation, and supporting from below an upper floor concrete and a water-proof layer by the perforated pipes. The disclosed structure also includes a water supply pipe and a water discharge pipe both communicating with the hollowed portion and the aboveground.
The conventional structure for storing water in the underground, however, requires a great space in operation of transporting and keeping the perforated pipes, which are to be installed in the hollowed portion, to and in the work site. Also, arranging the perforated pipes so as to fit with one another is not easy and positioning the perforated pipes in place takes time. Another problem is that manufacture of the perforated pipes pushes up a cost due to a complicated configuration thereof.
SUMMARY OF THE INVENTION
The present invention has been made in view of the problems stated above, and its object is to provide a stacked structure which is lightweight and strong in strength, the structure being not limited in applications to storing of water in the underground.
To achieve the above object, according to a first aspect of the present invention, there is provided a stacked structure comprising skeleton members each having mountain-shaped portions or skeleton part with substantially mountain-like shapes successively repeated in one section and substantially the same sectional form extending in a direction perpendicular to the section, the skeleton members being stacked together to form the stacked structure, wherein when stacking the skeleton members together, bottom ends of the mountain-shaped portions with substantially mountain-like shapes successively repeated in one of two adjacent skeleton members are arranged to cross top ends of the mountain-shaped portions of the other skeleton member.
According to a second aspect, there is provided a stacked structure comprising skeleton members each having mountain-shaped portions with substantially mountain-like shapes successively repeated in an X-axis direction and substantially the same sectional form extending in a Y-axis direction orthogonal to the X-axis direction, the skeleton members being stacked together in a Z-axis direction orthogonal to the X-axis direction and the Y-axis direction to form the stacked structure, wherein when stacking the skeleton members together, bottom ends of the mountain-shaped portions with substantially mountain-like shapes successively repeated in one of two skeleton members adjacent each other in the Z-axis direction are arranged to cross top ends of the mountain-shaped portions of the other skeleton member.
According to a third aspect, there is provided a stacked structure comprising skeleton members each having mountain-shaped portions with substantially mountain-like shapes successively repeated in section cut along a Z-axis orthogonal to the X-axis, and substantially the same sectional form extending along a Y-axis orthogonal to both the X-axis and the Z-axis, the skeleton members being stacked together along the Z-axis to form the stacked structure, wherein when stacking the skeleton members together, bottom ends of the mountain-shaped portions with substantially mountain-like shapes successively repeated in one of two skeleton members adjacent each other along the Z-axis are arranged to cross top ends of the mountain-shaped portions of the other skeleton member.
According to a fourth aspect, in the stacked structure according to the first, second or third aspect, the rear side of the mountain-shaped portions is shaped in conformity with the configuration of the mountain-shaped portions on the front side, and individual rear-side spaces are defined on the rear side of the mountain-shaped portions.
According to a fifth aspect, in the stacked structure according to the first, second or third aspect, the rear side of the mountain-shaped portions is shaped in conformity with the configuration of the mountain-shaped portions on the front side, individual rear-side spaces are defined on the rear side of the mountain-shaped portions, and reinforcing members are provided in the individual rear-side spaces to interconnect opposed slopes of the mountain-shaped portions on the rear side for reinforcing the mountain-shaped portions.
According to a sixth aspect, in the stacked structure according to the second or third aspect, bottom recesses provided at the bottom ends of the mountain-shaped portions in one of two adjacent skeleton members stacked in the Z-axis direction are engaged with top recesses provided at the top ends of the mountain-shaped portions of the other skeleton member, the bottom recesses are portions recessed when looking at the bottom ends from the rear side of the skeleton member, and the top recesses are portions recessed when looking at the top ends from the front side of the skeleton member.
According to a seventh aspect, in the stacked structure according to the second or third aspect, bottom recesses provided at the bottom ends of the mountain-shaped portions in one of two adjacent skeleton members stacked in the Z-axis direction are engaged with top recesses provided at the top ends of the mountain-shaped portions of the other skeleton member; the top recesses are portions recessed when looking at the top ends from the front side of the skeleton member, and provide hollow spaces each surrounded by first and second top slopes inclined in respective directions to cross the top end of the mountain-shaped portion, and a third top flat surface connected at both ends to the first and second top slopes and extended parallel to the top end of the mountain-shaped portion; the bottom recesses are portions recessed when looking at the bottom ends from the rear side of the skeleton member, and provide hollow spaces each surrounded by first and second bottom slopes inclined in respective directions to cross the bottom end of the mountain-shaped portion, and a third bottom flat surface connected at both ends to the first and second bottom slopes and. extended parallel to the bottom end of the mountain-shaped portion; each of the top end of the mountain-shaped portion and. the bottom end of the mountain-shaped portion has an included angle &thgr;; the first and second top slopes intersect at an angle &thgr; such that the first and second top slopes are inclined to separate away from each other outward and approach closer inward; the first and second bottom slopes intersect at an angle &thgr; such that the first and second bottom slopes are inclined to separate away from each other outward and approach closer inward; and in a state where the bottom recess is engaged with the top recess, the third top flat surface and the third bottom flat surface lie in opposed relation to each other, the first and second bottom slopes lie in opposed relation to the front side of the mountain-shaped portion of one adjacent skeleton member, and the first and second top slopes lie in opposed relation to the rear side of the mountain-shaped portion of another adjacent skeleton member.
According to an eighth aspect, in the stacked structure according to the first, second or third aspect, the rear side of the mountain-shaped portions is shaped in conformity with the configuration of the mountain-shaped portions on the front side, individual rear-side spaces are defined on the rear side of the mountain-shaped portions, and openings are provided to penetrate the mountain-shaped portions from the front side to th
