Bricklaying equipment includes a guideway extending along brick masonry being erected. A bricklaying machine displaces along the guideway. It has a robotic arm with an upper arm and a forearm. The upper arm pivots about a shoulder joint, and the forearm pivots relative to the upper arm at an elbow joint. A wrist joint permits a tool assembly, including a mortar-dispensing mechanism and a brick-gripping mechanism, to pivot relative to the forearm. The mortar-dispensing mechanism includes a form t...

The invention relates to an apparatus for the construction of monolithic of multi-level or pillar-framed buildings having suspended ceilings, said apparatus is provided with surface- and in given case working level-forming formwork shell surrounding the monolithic concrete form-space of the ceiling, formwork bearer supporting the formwork shell, furthermore actuating mechanisms, e.g. lifting units for lifting and lowering the formwork bearer, the actuating mechanism, e.g. lifting units are in fo...

A modular tower assembly for use with blown film extrusion processes, where modular tower sections each having identical columns/foot prints can be stacked on top of one another. Each module can have rectangular type platforms with walk decks about a central rectangular void middle. Staircases can be built into the side of all decks modules up to the top deck. Each of the four vertical legs of the deck modules has flat plate bottoms to stack on the deck surface of the module beneath, and side cr...

A free access floor comprising a plurlaity of units juxtaposed to both traversing and vertical direction, each unit comprising two right-angled triangular plates and first, second and third rectangular covers. Two triangular plates are so arranged to constitute a rectangle by facing their hypotenuses to each other. Two other side of each triangular plate have steps. Each triangular plate has three legs at its corners. The first, second and third rectangular covers are rested on the steps of the ...

An apparatus and method for manipulating a pole relative to a base fixed in the ground. The base is gripped and provides a rigid reference point. The pole is cradled and an actuator provides force to move the pole relative to the reference point. This can include detaching the pole from the base as well as inserting the pole on the base. As an optional feature, a pivot mechanism can be associated with the combination to allow the pole to be pivoted with respect to the base to lower the pole for ...

A one piece assembly of a small production unit (23) for panels intended for building comprises an upper tray (2) a bottom tray of longer length (1) a collapsible crane (7) situated on the upper tray (2) supporting the crane structure (7) is horizontally mobile with rollers (11) supported on rail (12) positioned on the bottom tray (1) without requiring an external support lying on the ground. The vertical movement of the upper tray (2) is assured by an assembly of screw jacks (4), plates (18), g...

A device for lifting a framework (65) optionally together with a portion of a building resting on said framework (65), and in particular a roof, relative to underlying walls. The device (63) is designed to be used as one of a plurality of such devices distributed around the framework (65) and it includes a wall plate (1) suitable for being fixed to the wall (3) and connected to guides (64) for guiding a cursor (76) suitable for co-operating with the framework (65), and controlled thruster (108) ...

An earthquake backstop support for mobile homes includes a cross-beam which underlies the pier-supported underframe of the home in closely spaced relationship to, but separated from, the underframe. In the event of displacement of the home from its piers, the beams of the backstop support support it in a level attitude and are carried on slidable shoes so as to permit sliding movement during continuing earthquake shocks.

Means for interconnecting adjacent panels of partitioning comprising a flanged member adapted to be secured to or formed integral with the vertical edges of each panel, each flanged member being provided with one or more flanges which mate with corresponding flanges of the flanged member of an adjacent panel to prevent separation of the adjacent panels along the line of the panels, each flanged member also being provided with an open longitudinal channel adapted to abut with a similar open longi...

An improved oil well drilling rig structure (10) is provided. The drilling rig structure (10) includes a base (32) for placement on the ground at a well site. The base (32) includes first and second ends (32a, 32b). A drill floor (14) supported on a floor box (12) having first and second ends (12a, 12b) is disposed parallel to and adjacent the first end (32a) of the base (32). The floor box (12) is coupled to the base (32) by spaced apart parallel legs (76, 78) each pivotally attached between th...
