Publication number: 20100115860Abstract: A girder element (1; 21; 31; 41; 53-57) for concrete formwork comprises a girder (4) for receiving external forces (10), a tension rod (5) extending behind the girder (4) and at least one lengthwise adjustable tensioning device that is interposed between the girder (4) and the tie rod (5), the local distance between the girder (4) and the tie rod (5) being adjustable by means of said tensioning device. The invention is characterized in that the lengthwise adjustable tensioning device is configured as a lengthwise adjustable compensation device (6; 6a, 6b) which is motor driven to adjust the length of the compensation device (6; 6a, 6b). A measuring device is used to determine the position (x) of the girder (4) in the area of the compensation device (6; 6a, 6b) relative to a desired position (xs). A control device (12) is used to adjust the length (L) of the compensation device (6; 6a, 6b) depending on the position (x) of the girder (4).Type: ApplicationFiled: June 3, 2008Publication date: May 13, 2010Applicant: PERI GMBHInventor: Hans Braun

Publication number: 20020088194Abstract: A very lightweight tubular building element for the construction of reinforced concrete floors and roofs; providing the formwork for the casting in place of the structural concrete and a high quality finished ceiling at the same time. It is a single component that can be installed easily and efficiently without heavy equipment or special craftsmanship; afterward the component is not removed, but stays permanently integrated in the concrete floor or roof. It forms a deck that is impervious, eliminating cumbersome cleaning during construction and leakage afterward, saving the common need of a costly waterproofing membrane over the slab. The formwork deck, composed of a plurality of the invention component, weighs less than four (4) pounds per square foot; and a single component for a common 15 feet span weighs less than 30 pounds, which can be easily handled by only one laborer.Type: ApplicationFiled: February 14, 2002Publication date: July 11, 2002Inventor: Manuel A.

Publication number: 20010004815Abstract: Lintels having metal side plates are described. In an exemplary embodiment, a lintel constructed in accordance with the present invention includes a generally rectangular frame of a height, length and thickness substantially corresponding to the dimensions of the opening in which the lintel is to be installed. The frame is formed by connected, first and second elongate chord members (e.g., nominal “2×N” members) that extend in spaced, substantially parallel, overlying relationship to each other. The subject lintel also includes at least one generally rectangular, metal side plate having at least first and second spaced groupings of integrally formed teeth extending from one side along opposite longitudinal edges thereof. The respective teeth groupings engage the first and second chords.Type: ApplicationFiled: January 16, 2001Publication date: June 28, 2001Inventor: Robert A. LePoire

Patent number: 5799457Abstract: A structural element for thermal insulation between two concrete structural components. An insulating body having metal reinforcing rods extending therethrough is to be attached to the concrete structural members with the rods extending within each member along either side of the insulating body. The rods running diagonally through the insulating body and extending along upper and lower edges of the insulating body so as to lie within upper and lower portions of the concrete structural members. Fire protection plates may be attached along upper and lower surfaces of the insulating body.Type: GrantFiled: February 18, 1997Date of Patent: September 1, 1998Assignee: Schoeck Bauteile GmbHInventors: Armin Schumacher, Gerhard Trunz

Patent number: 5465538Abstract: A prefabricated lintel having two spaced apart parallel upstanding legs extending along the length of the lintel and having laterally aligned holes defined therethrough and spaced therealong. The lintel further has a flat lower surface and an upper surface defining flat, horizontal shoulders positioned along outer edges of the lintel on opposite sides of the upstanding legs and extending the length of the lintel. The lintel is placed to span a doorway and a course of blocks is laid on the flat shoulders, with a second course laid on the first course and a rebar positioned on the upper surface. A plurality of wire stirrups, each defining a rebar receiving loop, are engaged over the rebar and extend through openings in the two courses with end portions of the stirrups engaged in each of the holes defined in the upstanding legs of the lintel. The block openings are filled with grout.Type: GrantFiled: September 7, 1993Date of Patent: November 14, 1995Inventor: John Powers, Jr.

Patent number: 5317847Abstract: A steel truss (10) spanning an opening (11) in a load-bearing CMU wall (111) is used as a structural support from which to hang hangers (12) having steel plates (13) on their lower ends. U-blocks (14) are placed on the hangers, and the space (20) between adjacent U-blocks (14) is filled with mortar. After the mortar hardens (typically 24 hours later), the trench formed by the hollow areas (15) in the U-blocks is filled with concrete, thus encasing the steel truss (the height of the truss is less than the distance from the lower interior of the U-blocks to the bottom of the CMUs above the U-blocks) and forming a steel-reinforced structural beam across the opening (11). CMUs (17) are then laid on top of the structural beam to continue the load-bearing wall above the opening.The truss preferably has attached at each end thereof a steel saddle (16) which serves to center the truss in the U-blocks.Type: GrantFiled: September 12, 1991Date of Patent: June 7, 1994Inventor: Barry J.
