Abstract: For a lateral face of the lattice girder, defined by an upper chord and a lower chord, the triangulation comprises compression bars substantially perpendicular to the chords, oblique tension bars of smaller length connecting the top of a compression bar to the lower chord, and other oblique tension bars of greater length, also connecting the top of a compression bar to the lower chord, at a point located further ahead toward the base of the next compression bar. This triangulation is used, in particular, for the jib and counterjib elements of tower cranes.

Abstract: The present invention comprises a sprayer boom and is incorporated in a spraying apparatus which includes a vehicle, a tank, hoses connected to nozzles, and the sprayer boom. The sprayer boom includes a number of wing sections each including at least one single-piece component cut from a sheet of metal to form a web or truss structure which replaces the usual rods and welds support provided to sprayer booms of this nature. Obtaining the single-piece component by cutting it from a sheet of metal rather than constructing the truss-structure by use of many rods reduces material and labor costs. Spaced apart rungs or tabs on the bottom of the sprayer boom provide openings through which sprayer nozzles are aimed while the nozzles, hoses and connectors remain mostly recessed within the boom which provides physical protection from wind and other damage and still allows easy access for repair.

Abstract: Column-beam building frame structure, wherein columns and beams are interconnected to distribute and share all lateral loads through collars that encircle columns at the nodal points of attachments between columns and beams. Each collar includes inner and outer components which seat, and gravity-lock together, during frame construction, and which also to offer a certain amount of immediate moment resistance to lateral loads. Tension bolt and nut assemblies lock the inner and outer collar components together, and with these assemblies in place, the collars (which circumsurround the beams) function to deliver beam moment loads as plural-position, angularly distributed compression loads to different side regions of columns.

Abstract: A construction beam includes a pair of lateral members and a resilient web extending therebetween, so as to present a cross-sectional profile corresponding to commonly used construction beam members. The resilience of the web helps to attenuate sound transmission through the beam from one lateral member to the other. Ends of the resilient web are fixed to respective ones of the lateral members on opposite sides of an imaginary reference plane passing orthogonally through both of the lateral members. In particular, in a wall frame, the lateral members are mounted at opposite ends thereof to end plates consisting of other construction beams according to the present invention. When used in a frame of a building structure, the lateral members of the end plates on the same side are attached to the surrounding structure, leaving the other side of the frame resiliently free floating.
