摘要:
A device for filling or creating a void within a construction medium. The device has a body having at least one inflatable body portion. Each inflatable body portion has one or more inflatable cavities. There is at least one valve member fluidly connected to the one or more inflatable cavity to control flow of fluid into and inflate said cavity. In-use, the one or more cavities are shaped to substantially fill or create the void in a construction medium when in an inflated state.

The invention relates to an apparatus and method for moulding a substantially hollow building panel (12) of the kind having spaced opposed outer panel walls (14) interconnected by a plurality of spaced formations 16 such that adjacent formations each define a void (18) therebetween. The apparatus including a mould (20) having means to define an outer surface of least one of the outer panel walls and a plurality of spaced apart inflatable void forming plug members (26) connectable with an inflation means, disposed within the mould. The apparatus further including a means to introduce a settable wet mix into the mould.

摘要:
A form for creating cavities within large concrete structures, wherein the formed is created by interconnecting a plurality of section members, the section members having flexible mold skeleton members retaining polymer-aggregate panel members, and wherein the form may be internally pressurized to increase its rigidity and weight-bearing capability. The mold skeleton members have annular and longitudinal flanges that are used as planning guides to form the external surface of the polymer-aggregate panel members. Preferably, spacer members are inserted between the annular and longitudinal flanges and the spacer members are used as planning guides. The adjacent section members are mechanically joined to each other, such that the form may be disassembled and re-used.

摘要:
A method for forming caves on a construction, including steps of: preparing an envelope corresponding to the cave to be formed on the construction. Filling a fluid such as a gas or a liquid into the envelope to form a solid envelope; embedding the envelope in the construction to be grouted to define a grouting mold cavity. Deflating or draining the envelope of the fluid after a filling filled in the grouting mold cavity is hardened to achieve a construction with the caves.
摘要:
A form assembly which may be used to provide a core portion in a concrete or other cast structure. A pair of former elements having interfitting hooks and flanges which are normally urged apart by a resilient sleeve which fits over the former elements. The sleeve biases the former elements to a collapsed position in which they may be inserted and removed. An inflatable tube is interposed between the former elements and may be inflated to move the elements to an expanded position wherein forming surfaces of the elements cooperate to provide a core about which concrete or the like may be poured.
