Abstract: This invention relates to a set of pieces or parts making up a system of metallic adjustable formwork for concrete structures in civil Works which functions is to allow the assembly, junction and adjustment of the formwork system in the most efficient way with the use of a system of adjustable formwork which looks for to use the shorter quantity of metallic panels as accessory during the project execution. The way as the each element has characteristics of specially defined shape, size and function to get a rigid structure, which allow to build a mold over which the concrete is poured maintaining their characteristics and perform such functions rapidly, efficiently and securely.

Abstract: A precision fabrication form system for preparing a poured-concrete (with upwardly projecting anchor bolts) footing for anchorably supporting the base of an elongate, upright, structural-frame column. The system includes a reversibly stackable plurality of independent, intercooperative, fabrication-form templates—grade, pedestal, base-plate, anchor-bolt and centerline—reversibly assembleable in a predetermined stack order above a prepared ground excavation into which concrete pouring to be associated with such a footing is to occur, certain ones of these templates being infinitely adjustable relative to one another and to the ground in both pre-pour and post-pour conditions to accommodate staged, precision, X-axis, Y-axis, Z-axis, and pitch, roll and yaw axes dispositions for the concrete and anchor bolts in such a footing.

Abstract: The invention provides a cable protection and guide apparatus allowing a protecting and guiding apparatus to be downsized by reducing a radius of a polygonal bend formed when link plates are bent back in a cable longitudinal direction between a cable stationary end and a cable mobile end and achieving smooth relative movements of shoes that face with each other between the upper and lower cable-bend inner circumferential sides by easing impact energy and impact sound of the shoes. The shoes provided on the cable-bend inner circumferential sides of the pair of link plates laterally and separately disposed have slidable-contact portions having parallelogram slidable-contact surfaces configured to face to and to mutually slidably contact with each other between upper and lower cable-bend inner circumferential sides.

The means of mutual fixing are constituted by hinges (8), fixed to the edges of the plates, and by corresponding oblong orifices (9), evenly distributed on the plate (1) in transversal direction. The means of immobilization are constituted by a through hole (11) made in the shaft of each hinge (8) and by a sliding element (12) provided with a wedge-shaped end (13).

Abstract: A building member forming apparatus comprises panels and a conversion corner bracket. The panels are typically dimensioned in metric units. The conversion corner bracket can include a leg having a predetermined width and a body configured to chamfer a building member. The conversion corner bracket is securable to the panels to form an orifice. When the orifice receives a construction material, the building member can be formed. By using the panels and the conversion corner bracket, the building member that has been formed within the orifice is chamfered and possesses U.S. customary units. Thus, the conversion corner creates a chamfer upon the building member and permits dimensioned panels with one set of units to form a building member with another set of units. Preferably, the leg and the body are not symmetrical and include bores or apertures that align with bores or apertures in the building member forming apparatus.

The chain includes at least one bar which is resilient about its longitudinal axis and which extends in the longitudinal direction of the chain, more particularly in the receiving space thereof. Upon pivotal movement of the chain link members relative to each other the bar produces return forces which oppose the pivotal movement.

A draw member or bolt interconnects the cam and the stem extends generally parallel to the inclined and cam surfaces. In the open position, the stem and cam of the union may be received in or withdrawn from a cavity in a support boom. In the locked position, the union is rigidly connected with the support boom.

Abstract: A form for erecting structures having an plan shape, any generatrix and possibly changing wall thickness includes an inner form (1) and an outer form (2). Circumferentially closed support rings (5,6) are arranged horizontally spaced from the inner form as well as from the outer form. Radially aligned sleeves (35) are provided in the support rings (5,6). Threaded spindles (7,8) are slidably but fixedly held in the sleeves (35). One end of each threaded spindle (7,8) engages form carriers (11,12) which rest against the form carriers (3,4). The inclination of the form plates (3,4) or the wall thickness of the structure to be erected can thus be adjusted. Web members (13,14) are provided between the form plates (3,4) in circumferential direction of the form, the web members engaging over the form plate edges at the rear sides thereof. The web members have a support (15,16) on the surface facing the structure in the region between the side edges of the spaced-apart form plates (3,4).

Abstract: Multipurpose concrete form panels are constructed using cross stiffener members for resistance to deflection under load. Each of the cross stiffener members is formed of a base strip of metal with a pair of parallel ribs of hat section extending therefrom and joined to opposite side rails of the form panel. Rail stiffener strips are fastened to the side rails on alternate sides of the rail for added rigidity. Bores for connecting pins extend through the side rails to join the panels side by side to form a wall or, using a corner form, to form a column. Bores through the side rails are positioned between the cross stiffener members and between the ribs in each pair of ribs for joining the side rails together with continuity of the cross stiffener members for maximum dispersal of stress. Holes for wall ties extend through the face of the form panel and between the ribs in each pair of ribs. Fasteners for the ends of the wall ties engage the pairs of ribs to disperse localized stress.
