US3984989A — Means for producing subaqueous and other cast-in-…

Claim 1

Independent Claim 111 words

A device for molding a cast-in-place concrete or like structure of predetermined shape and proportions in a subaqueous or other situs from self-hardenable fluid cementitious material comprising: container means of flexible, generally porous-walled fabric, and a matrix frame having means thereon for maintaining said matrix frame in rigidly affixed condition at the situs, and including means defining fixedly restrained body-shaping cavity wall portions for limiting distension of said flexible, generally porous-walled fabric of said container means against tensional restraint maintained between said fabric and fixedly restrained body-shaping wall portions of said matrix frame upon being filled with the fluid cementitious material to form a structure therein of like shape and size.

Claim 2

Independent Claim 111 words

A device for molding a cast-in-place concrete or like structure of predetermined shape and proportions in a subaqueous or other situs from self-hardenable fluid cementitious material comprising: container means of flexible, generally porous-walled fabric, and a matrix frame having means thereon for maintaining said matrix frame in rigidly affixed condition at the situs, and including means defining fixedly restrained body-shaping cavity wall portions for limiting distension of said flexible, generally porous-walled fabric of said container means against tensional restraint maintained between said fabric and fixedly restrained body-shaping wall portions of said matrix frame upon being filled with the fluid cementitious material to form a structure therein of like shape and size.

Claim 3

Dependent Claim 29 words

The device of claim 1, wherein said matrix frame includes a substantial wall area of openwork material having distension-limiting connections with said generally porous-walled fabric of said container means.

Claim 4

Dependent Claim 33 words

The device of claim 2 wherein said matrix frame surrounds said container means and said distension-limiting connections include body-shaping contact of said generally porous-walled fabric of said container means with said openwork material.

Claim 5

Dependent Claim 33 words

The device of claim 1 wherein said last-mentioned means comprises restraining portions on said openwork material and restrainingly engaged by corresponding portions of said generally porous-walled fabric for accomplishing such limited distension thereof.

Claim 6

Dependent Claim 68 words

The device of claim 1 wherein said last-mentioned means limits distension of said generally porous-walled fabric of said container means to such given shape and size, upon the same being filled with such fluid cementitious material, to a point capable of being indicated by a tendency thereof to ooze through the pores of said fabric, to form said structure of like shape and size within said container means.

Claim 7

Dependent Claim 100 words

Apparatus for forming structural bodies from self-hardenable fluid cementitious material on a surface of a subaqueous or other situs, comprising: at least one, self-supportingly rigid openwork matrix means of substantial broad lateral area and having supporting means for supporting the same in self-supportingly rigid, upright condition on a surface of the situs, and bag-like container means including vertical body-forming walls, corresponding portions of said body-forming walls being restrained against distension by engagement with said rigid openwork matrix means for determining the volumetric size and shape of the desired structural body, upon filling said container means with such fluid cementitious material.

Claim 8

Dependent Claim 100 words

Apparatus for forming structural bodies from self-hardenable fluid cementitious material on a surface of a subaqueous or other situs, comprising: at least one, self-supportingly rigid openwork matrix means of substantial broad lateral area and having supporting means for supporting the same in self-supportingly rigid, upright condition on a surface of the situs, and bag-like container means including vertical body-forming walls, corresponding portions of said body-forming walls being restrained against distension by engagement with said rigid openwork matrix means for determining the volumetric size and shape of the desired structural body, upon filling said container means with such fluid cementitious material.

Claim 9

Dependent Claim 42 words

The apparatus of claim 6 wherein said container means is of generally porous-walled fabric adapted to allow relatively small quantities of such fluid cementitious material to ooze through the fabric pores during filling of said container means with such fluid cementitious material.

Claim 10

Dependent Claim 134 words

A mold for forming a cast-in-place concrete or like body from fluid self-hardenable cementitious material to given shape and size in a subaqueous or other situs comprising: matrix means having closure wall means defining bounds of a body-forming cavity of substantially such given shape and size, means for affixing said matrix means at the situs against outward distortion of said closure wall means from such given shape and size of such matrix means, said closure wall means having a substantial area of tension-restraining openwork material, flexible-walled bag means, and means for retaining said bag means within said body-forming cavity for reception therein of the fluid self-hardenable cementitious material to expand the walls of said bag means into said closure wall means, and thereby to form a self-hardenable body of such given shape and size.

Claim 11

Dependent Claim 134 words

A mold for forming a cast-in-place concrete or like body from fluid self-hardenable cementitious material to given shape and size in a subaqueous or other situs comprising: matrix means having closure wall means defining bounds of a body-forming cavity of substantially such given shape and size, means for affixing said matrix means at the situs against outward distortion of said closure wall means from such given shape and size of such matrix means, said closure wall means having a substantial area of tension-restraining openwork material, flexible-walled bag means, and means for retaining said bag means within said body-forming cavity for reception therein of the fluid self-hardenable cementitious material to expand the walls of said bag means into said closure wall means, and thereby to form a self-hardenable body of such given shape and size.

Claim 12

Dependent Claim 32 words

The mold of claim 8, wherein said bag means comprises a generally porous walled open-topped container, and means are provided for mounting said bag means in depending relationship within said body-forming cavity.

Claim 13

Dependent Claim 47 words

The mold of claim 8, for forming a walled structure, wherein said closure wall means includes spaced, upright co-extending walls of openwork material, and walls of said bag means are disposed for distention thereof by the fluid cementitious material into body-shaping engagement with said spaced co-extending walls.

Claim 14

Dependent Claim 30 words

The mold of claim 10 wherein said spaced, co-extending walls and said bag means within said body-forming cavity are continuous for forming a continuous walled body defining a passage therethrough.
