Abstract: The present invention relates to a stack or a vertical pipe for the flow of gas, said stack or pipe comprising a suspension mast defining a vertical axis; at least one supple surface, open downwardly and upwardly, and symmetrical with respect to this axis; substantially horizontal, rigid hoops, viz. an upper hoop and a lower hoop respectively fast with the upper and lower periphery of the surface, each hoop being symmetrical with respect to said axis; supple bearing ties suspending the upper hoop from the mast; and stays connecting the lower hoop to a fixed lower point of the mast or the ground to stretch the supple surface in a vertical direction. The invention finds application in the entire production or extension of stacks or pipes such as atmospheric cooling towers.

Abstract: Anchor rods are protected against corrosion by inserting sealant within an anchor eye cap recess and bottom nut recess before fastening the eye and anchor member to the rod. Protective rod covering also is within the recesses.

Abstract: There is disclosed a post footing form holder and stabilizer system which is formed by a plurality of legs having upper and lower ends, each of the legs provided with means for mounting the legs to a post form along the lower end thereof, post form carrying means associated with the legs for accommodating and carrying the post form along the lower end thereof, the legs being further provided with stop means mounted thereon and spaced a distance upwardly from the lower end of the legs, and including stabilizer means associated with the post form holder for stabilizing and maintaining the post form in position when constructing a post footing.

Abstract: A beam-type pile such as a double-T beam is secured to a sheet piling after driving a pile into the ground in a usually slanted position. The pile is secured to the sheet piling by welding a pull bar to the web of the pile so as to protrude from the head thereof. The protruding pull bar portion is partly inserted into a cutout of the sheet piling. This protruding pull bar portion is secured in the sheet piling by a support plate including a slot through which the pull bar portion is extended. The support plate is welded to the inside wall surface. The pull bar portion protruding into the sheet piling is further fastened by a reinforcing plate disposed upright relative to the protruding pull bar position and welded thereto and the support plate.

Abstract: A swimming pool construction has an outer shell defined by a plurality of metal sections which are secured to each other and have substantially vertical walls defining the swimming area of the pool. Each metal section includes a coping support extending outwardly of the swimming area in a horizontal direction from the upper end of each vertical wall, and a coping is secured to the coping support about the outer periphery of the swimming area. Transversely spaced sockets for receiving one end of transversely spaced handrails of a swimming pool ladder are secured to the outer end of the coping support prior to the formation of a concrete deck or walk around the outer periphery of the swimming pool. Structural supports are secured to the outer shell of the swimming pool to provide support for the concrete deck or wall. The structural supports extend outwardly of the metal sections of the pool and support horizontally disposed, top angle members which are disposed outwardly of the coping.

Abstract: There is disclosed a post footing form holder and stabilizer system which includes a collar formed by a peripheral side wall and being open at the top and bottom ends thereof, a flange positioned along the bottom edge and extending inwardly for a short distance thereby to act as a bottom stop for a post form inserted within the collar, a plurality of legs mounted on the collar and extending downwardly therefrom and having stop means associated with each leg, each of the stop means being spaced a distance upwardly from the lower end of the legs, and stabilizer means formed by a clamp ring consisting of a ring wall having an interrupted portion, clamp means overlying the interrupted portion and constructed to draw the opposed ends of the interrupted portion together and positionally lock in a closed position, the ring further including a plurality of tie means mounted thereon along the outer surface and a plurality of stabilizer rods constructed for attachment to the tie means at one end, and to the ground surf

Abstract: An in-ground swimming pool having a plurality of panels; the vertical edges of each adjacent panel seized between a front wall-joint and rear back-up joint having a rearwardly extending U-shaped channel to receive one side edge of a triangular brace; another U-shaped channel to receive the other side edge of the triangular brace; another U-shaped channel at the top of each panel to receive the edge of a deck member; a double channel having a regular position attached at the top of the panels to receive the outer edge of a horizontal deck; another double channel having a regular channel, receiving the bottom of each panel, and offset channels on each double channel receiving an outer edge of the deck; each offset channel having a brace attached at each end in the offset channels.

Abstract: The combination of a sheet of individual tiles attached together being mounted to a fiber glass shell and the method of constructing same. A plurality of panels are attached by adhesive means to a fiber glass shell. Each panel includes a plurality of individual tiles having edge portions attached to the edge portions of adjacent tile. The panels and the fiber glass shell are produced at a location remote from the final construction site. The fiber glass shell, configured as a shower stall or as a bathtub enclosure, is attached to a plurality of upright wooden studs. Tabs are provided on the fiber glass shell to receive conventional fastening devices extending into the studs. The fiber glass shell is provided with a rough, inwardly facing surface which adhesively receives the plurality of panels. In one embodiment, the shell includes a thickened top rib positioned flush with the panels whereas another embodiment includes a trim strip blending the panels into the shell.

Abstract: A below ground swimming pool formed of light-weight framed, wood sheet walls arranged within a preformed pool shaped hole, with a water impervious, thin plastic sheet liner covering the inside surfaces of the walls and the ground enclosed by the walls, and with the walls being held against collapsing inwardly, upon draining of the pool, by braces secured to the outer or ground side of the walls. The braces are formed with horizontally extending legs located at the lower edges of the walls so that such legs are weighted by the ground to maintain the braces and walls in position and so that such legs also function as support footings for the walls.

Abstract: A tie for connecting together parts of a structure, for example a stay for suspending the deck of a bridge from a tower, is constructed so that its length can be adjusted in a simple manner with the tie in service. The tie is made up from several stressed steel tendons, enclosed in a protective sheath filled with hardened material. At its ends the sheath incorporates anchoring devices for the transfer of the pull from the tie to the structure. The sheath forms a conduit whose ends are fixed securely to the anchoring devices. The conduit is isolated, throughout its length, from the structure so as to be capable of sliding longitudinally with respect thereto. At least one of the anchoring devices includes connection means for the active part of a tensioning apparatus and also includes means for bearing against the structure. This bearing means is adjustable on the anchoring device in the longitudinal direction of the tie.
