DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a permanent form for placing a basement concrete wall. More particularly, the present invention relates to a permanent form which is left integrally with a basement concrete wall placed and can discharge redundant water in a fresh concrete, artesian spring, leakage water or the like through the basement concrete wall.
PRIOR ART
One example of conventional forms for placing an basement concrete wall is disclosed in FIG. 2 in Japanese Utility Model Publication No. 3-28670 published on May 19, 1991. The prior art is so adapted as to affix a sheet having a flute serving as a water-conduit channel and a cloth serving as a percolation layer to a substrate having predetermined strength and using the sheet affixed to the substrate as a concrete form. If a basement concrete wall is placed using this concrete form, redundant water in fresh concrete flows into the flute through the cloth, flows downward through the flute, and is discharged from the bottom of the form before hardening the concrete, so that the hardening rate of the concrete is increased, to improve the surface state and physical properties thereof. After hardening the concrete, the form is removed from the basement concrete wall.
However, there are some problems in the prior art. For example, the sheet must be affixed to the substrate, resulting in poor workability. In addition, the form is removed from the concrete, thereby to make it impossible to prevent the entrance of water leakage into the interior due to, for example, the occurrence of a crack after hardening the concrete.
Therefore, a permanent form having a water-conduit channel, a percolation layer and a substrate integrally formed in advance is disclosed in Japanese Patent Laid-Open Gazette No. 3-281863 laid open on Dec. 12, 1991 and Japanese Patent Laid-Open Gazette No. 4-70467 laid open on Mar. 5, 1992.
According to the prior arts, a sheet need not be affixed to the substrate, thereby to make it possible to improve workability. Moreover, the form need not be removed from the placed concrete, so that water leakage after hardening the concrete can be discharged from the bottom of the form, thereby to make it possible to prevent the entrance of the water leakage into the interior. Since the form is so constructed that the water-conduit channel and the percolation layer are affixed to the substrate, however, there are some problems. Specifically, the function, especially the strength of the form is greatly changed depending on the material of the substrate (veneer or the like). In addition, the strength of the form depends on only the substrate. If an attempt to obtain sufficient strength is made, therefore, the thickness of the entire form is increased and the weight thereof is increased.
SUMMARY OF THE INVENTION
Therefore, a principal object of the present invention is to provide a new permanent form for placing a basement concrete wall.
Another object of the present invention is to provide a permanent form for placing a basement concrete wall capable of improving workability and the leak-prevention function for the basement concrete wall.
Still another object of the present invention is to provide a permanent form for placing a basement concrete wall being lightweight and having practically sufficient strength.
A further object of the present invention is to provide a permanent form for placing a basement concrete wall capable of preventing dew condensation.
A permanent form for placing a basement concrete wall according to the present invention is integrated with a placed basement concrete wall, and has a panel forming a basement concrete wall surface and a water-conduit channel for discharging water from the basement concrete wall which are integrally formed of synthetic resin.
According to the present invention, the panel and the water-conduit channel support a form structure in cooperation, thereby to make it possible to so form the permanent form for placing a basement concrete wall as to be lightweight and have high strength. In
