Abstract
Abstract Outwardly extending support members are integrally joined to a reinforced concrete hull of a swimming pool. Peripheral deck slabs rest on the support members preventing deck pivoting due to earth settlement. The support members engage the sidewalls of the pool at a depth sufficiently below the water level such that water pressure provides a significant counteracting force to the sidewall in the area of greatest stress. Joints between adjacent deck slabs are formed above the support members so that each deck slab is at least supported at its opposite ends.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
A swimming pool structure comprising: a monolithic pool hull of pneumatically applied reinforced concrete formed against the walls of an excavated basin, the hull having upstanding sidewalls rimmed at their upper periphery by a bond beam, the sidewalls having integrally formed footers extending outward at spaced intervals, the footers being formed by pneumatic application of concrete into grooves in the walls of the basin contemporaneously with the formation of the sidewalls, at least one poured concrete deck slab, each deck slab being tied in front to the bond beam and supported at opposite ends by footers, and means disposed between footers for forming a cavity between the ground and the underside of the deck slabs, wherein each footer has an upper horizontal supporting surface essentially flush with the upper surface of the bond beam, a lower diagonal surface meeting the sidewall below the bond beam at a depth sufficient to prevent intolerable stresses in the sidewall, and a rear surface extending essentially vertically downward from the horizontal surface to the lower diagonal surface.
Claim 2
Dependent Claim
173 words

Claim 3
Dependent Claim
43 words
The structure of claim 1 wherein a generally triangular-shaped reinforcing bar extends from a point in the bond beam to an elbow bend near the rear surface of the footer, and from the elbow bend diagonally back to a point in the sidewall.
Claim 4
Dependent Claim
115 words
In combination, a swimming pool and diving board comprising: a concrete pool hull formed in an excavated basin, a cantilevered concrete deck projecting outward from the pool hull, a concrete pad disposed on the ground adjacent to the deck, a joint separating the deck and the pad, reinforcing bars extending through the joint to tie the pad to the deck, a first standard anchored in the pad, a second standard anchored in the deck, a diving board secured at one end to the first standard and supported along its length by the second standard, and supports attached to the pool hull for supporting the underside of the deck on opposite sides of the diving board.
Claim 5
Dependent Claim
115 words
In combination, a swimming pool and diving board comprising: a concrete pool hull formed in an excavated basin, a cantilevered concrete deck projecting outward from the pool hull, a concrete pad disposed on the ground adjacent to the deck, a joint separating the deck and the pad, reinforcing bars extending through the joint to tie the pad to the deck, a first standard anchored in the pad, a second standard anchored in the deck, a diving board secured at one end to the first standard and supported along its length by the second standard, and supports attached to the pool hull for supporting the underside of the deck on opposite sides of the diving board.
Claim 6
Independent Claim
76 words
A method of forming a cavity under a swimming pool deck comprising the steps: (a) forming support members for the deck, (b) providing a bed of loose fill between the support members, (c) saturating the fill with water, and (d) pouring concrete on the bed and adjacent support members while the fill is substantially saturated, whereby as the fill is allowed to dry it will settle and fall away from the concrete thereby forming the cavity.
Claim 7
Independent Claim
76 words
A method of forming a cavity under a swimming pool deck comprising the steps: (a) forming support members for the deck, (b) providing a bed of loose fill between the support members, (c) saturating the fill with water, and (d) pouring concrete on the bed and adjacent support members while the fill is substantially saturated, whereby as the fill is allowed to dry it will settle and fall away from the concrete thereby forming the cavity.
