Definitions

  • This invention is concerned with a portable permanent form for rapidly forming multiple precast concrete structures comprising generally U shaped building component ⁇ of the general type disclosed in my US patents 5,081,805 PRE-CAST CONCRETE BUILDING UNITS AND APPARATUS FOR MANUFACTURE THEREOF and 5,205,943 APPARATUS FOR MANUFACTURE OF PRE-CAST CONCRETE BUILDING UNITS.
  • a portable permanent form for rapidly forming multiple precast concrete structures comprising generally U shaped building component ⁇ of the general type disclosed in my US patents 5,081,805 PRE-CAST CONCRETE BUILDING UNITS AND APPARATUS FOR MANUFACTURE THEREOF and 5,205,943 APPARATUS FOR MANUFACTURE OF PRE-CAST CONCRETE BUILDING UNITS.
  • Such a form may be used for example for rapidly constructing U shaped building components of semi- room size comprising spans of approximately 4 meters wide by 3 meters deep, with parallel side walls or
  • the forming apparatus can be operated with only one or two workmen and is adjustable whereby it is not necessary to construct new forms each time a larger or narrower, longer or shorter room is reguired.
  • the present invention may thus provide a portable form apparatus which is flexible in use.
  • a further advantage since it is sturdy and permanent, it produces repetitive and accurately dimensioned units as opposed to units constructed with impermanent forms which often have considerable variations. It is fast and inexpensive and significantly lowers the unit cost of the building components made with it.
  • semi-room pre-cast building component units are especially suitable for constructing relatively simple and sturdy structures particularly in remote areas and in the absence of skilled labour. It is thu ⁇ important that the unit ⁇ may be fabricated with a minimum of carpentry or masonry skills. Ideally they should be competitively erected by common labourers with a minimum of training.
  • the purpose of the present invention is to provide a form or molding apparatu ⁇ that may be u ⁇ ed multiple times. Preferably it is easily adjusted to form different size pre ⁇ cast units, and can be operated readily with only one or two un ⁇ killed labourer ⁇ .
  • a re-usable form for casting concrete building components of U-shaped cros ⁇ -section comprising side panels defining an open-bottomed moulding space, the form including an end opening closable by a movable door whereby, with the door opened, the form may be laterally moved off a completed building component resting on a stationary support surface, the component passing through the end opening.
  • the technique ⁇ of the pre ⁇ ent invention it i ⁇ po ⁇ ible to remove the form ⁇ a ⁇ ⁇ oon a ⁇ the concrete ha ⁇ initially ⁇ et.
  • the form can be removed readily from the ⁇ tructure ju ⁇ t poured and moved a ⁇ hort distance, for example on jack attached wheels, to an immediately adjacent site. Another structural unit can then be poured in a very short period of time, because of the minimal preparation required to carry out each pouring operation.
  • the form can be used on site adjacent to a building project eliminating transport and handling cost ⁇ and logi ⁇ tical problem ⁇ a ⁇ ociated with off-site prefabricated components.
  • the form may be adju ⁇ table to produce all required room ⁇ izes and wall thicknes ⁇ e ⁇ .
  • a preferred form of the pre ⁇ ent invention ha ⁇ at one end a generally U ⁇ haped frame which lie ⁇ flat on the underlying surface.
  • the underlying ⁇ urface preferably comprise ⁇ a flat ⁇ heet of metal which ⁇ erves, in effect, as a portion of the base form surface.
  • the base surface can be a large steel sheet or plate. Since the form is moved from one section to another after each u ⁇ e it would eliminate the nece ⁇ ity of putting in place a ⁇ econd ⁇ eparate ⁇ heet a ⁇ a form part.
  • the base of the U is compri ⁇ ed of two overlapping hollow channel members ⁇ o a ⁇ to be expan ⁇ ible.
  • the upwardly extending arm ⁇ cf the are formed from adju ⁇ table height channel beam ⁇ .
  • a pair of parallel horizontal frame ember ⁇ are attached to the top of the uprights and extend to the other end of the form.
  • These frame member ⁇ are ⁇ lidably received in sleeves fixed to the top of an adjustable height, inverted U-shaped frame at the other end of the form. In this way the form is adjustable in length and height.
  • the bases of the U-shaped and inverted U-shaped frames are also telescopically adjustable to vary the width of the form.
  • the legs of the inverted U-shaped frame lie outwardly of the central mould ⁇ pace, allowing the form to ⁇ traddle and move pa ⁇ t a completed moulded unit.
  • each horizontal frame member Pivoted from each horizontal frame member are opposed pairs of counterbalanced arms. These support side panels of the form. At one end of the horizontal frame member ⁇ there are longitudinally slidable hanging bracket ⁇ , from which ⁇ wing ⁇ a U- ⁇ haped end clo ⁇ ure cover of the form. Cylindrical ⁇ pacer ⁇ may be provided to keep the ⁇ ide panel ⁇ the proper distance apart.
  • the corners of the frame have jacks to jack down an extension on which caster wheels are carried so that when a cast unit is set up the whole frame may be moved to the next base sheet ⁇ pace.
  • the concrete is poured in each side and in the base over the floor plate up to the desired thickne ⁇ .
  • Rebar ⁇ or mesh reinforcing may be utilized as called for in the particular specification ⁇ .
  • This device is simple to construct using basic welding or bolts.

Coffrage réutilisable pour composants de construction préfabriqués à section en U comprenant un châssis réglable (6) doté de membres supérieurs horizontaux (24, 26) auxquels des panneaux latéraux s'équilibrant (87, 91') sont fixés de manière à pouvoir pivoter. Le châssis est monté sur roulettes pour pouvoir être déplacé à différents endroits d'une plaque support (4) à chacun desquels un composant peut être coulé. Une porte à charnière fermant une extrémité (50, 55), qui peut s'ouvrir en même temps que les panneaux latéraux (87, 91'), est décrite pour permettre d'enlever le coffrage d'un moulage terminé pour l'amener à un nouvel endroit de la plaque support (4).
