Abstract: Apparatus for forming, compacting and finishing the top surface of concrete poured between a pair of removable longitudinally extending parallel opposed forms. The apparatus, which is self-propelled, travels along the tops of the forms. A heavy wooden vibrator member disposed at the forward end of the apparatus may be shaped so that concrete beneath the vibrator is formed and compacted to a depth which varies along transverse axes of the forms. The structural members of the apparatus may be interchanged or adjusted to adapt the apparatus for use with forms of arbitrary spacing. Simple adjustments may also be made to permit the apparatus to traverse forms of unequal height. Removable "skirts" enable use of the apparatus with relatively narrow forms supported above the grade on which the concrete segment is formed--the skirts serve as a "travelling form" to prevent poured concrete formed and compacted by the vibrator spilling beneath the forms.

Abstract: Plant comprising a rotary drum with a horizontal rotary axis lined, over its outer cylindrical surface with molding means and adapted to pass said molding means during rotation, before various working stations such as concreting, hardening, stripping and core positioning stations. The drum is equipped with beams with a composite profile fixed, notably by welding, longitudinally on the outer periphery of the drum. The beams have a cross-section which has zones adapted to form a roller track parallel to the longitudinal axis of the drum for the rolling and guidance of compacting means for the concrete. It is equipped with fastening means for the molds in a position situated radially outwards with respect to said roller track. It also has sufficient mechanical strength to absorb the major part of the prestressing forces exerted on the cores in the case of manufacturing prestressed concrete elements.

Abstract: An apparatus for forming embankments comprising a trapezium-shaped shield open at top and bottom and rearwardly. Material for the embankment is introduced into the top of the shield in slurry form and the difference in level between the slurry contained by the shield and the water outside the shield results in a force on the end wall of the shield. This causes the shield to travel end-wall first along the surface on which it is supported. As it moves forward, the shield will leave behind it an embankment formed to the same trapezium-shape as the shield itself. So that a layered form of embankment may be constructed, the shield may be fitted with a number of hoppers each associated with the formation of a particular layer.

Abstract: A machine for making cement blocks is provided which may be conveniently used on the site of a building construction. The device provides female dies into which fluid cement or flowable concrete mix is distributed whereupon male dies are lowered to properly form the cement into blocks. The male and female dies are then conveniently lifted above the height of the blocks and the entire machine moves forward a specified amount whereupon the female dies are lowered and the process begins again. The entire procedure may be carried out automatically in response to a preprogrammed sequence of events, or the process may be carried out by manual manipulation of a control panel.

Abstract: A machine for horizontal casting of concrete wall panels and slabs and for assembling them together to form room units or single-story buildings.The machine includes a wheeled frame, movable along a rail-track; two form-erectors, rotatable parallel to the rail-track; two form-strippers, rotatable across the track, and a lifting mould. All edges on the form-erectors and form-strippers are detachable and must be taken away before rotating.When used at the plant, the machine erects the room units on two trailers (one on each side of a casting station). A typical technological cycle starts with erecting a cross wall panel on an incomplete room unit. For this purpose the form-stripper rotates into vertical position, the machine moves close to the room unit, and the panel is released with a bottom hinged lock bracket. After the panel is fixed, the room unit, having been on the trailer, is ready for transportation to the job site.
