摘要： A interlocking highway barrier structure and system are described in which rigid upright barrier sections are disposed end to end in interlocking relationship with one another. Each of the sections of the system can have a grooved end to accommodate and engage with a similar adjacent end of the section next to it. The ends of each section of the system are provided with interlock plates for connecting together the adjacent sections. Each interlock plate is attached to its respective section and has an extending vertical edge which is bent into a "U" shaped cross-section to engage a similar edge or lip on the interlock plate of the adjacent section such that lateral movement of the respective plates and sections is prevented. The respective sections of the system can, however, be easily implaced or removed by vertically displacing the sections.

摘要： A method and apparatus for post-tensioning a concrete slab. A tendon member is pre-formed to define an enclosed area yet fit within a form. The tendon member has ends which extend past the form. Concrete is poured around the tendon with the tendon being positioned within the periphery of the concrete structure to form a large central area bounded by the tendon and an exterior portion which surrounds the enclosed area of the tendon. The tendon is anchored within said concrete by anchors secured to the ends of the said tendon and placed under an original tension of around 28,000 p.s.i.

摘要： A highway traffic lane barrier is composed of precast, reinforced concrete barricades which are joined together in alignment with each other by a horizontally and vertically tapered, vertical tongue-and-groove arrangement which is integrally molded on the ends of each barricade, with the wider portion of the taper at the bottom to facilitate the removal of one piece of barrier within an installation.

摘要： A prefabricated, reinforced construction panel consisting of a cast, concrete slab which is reinforced by rigid channels or studs. The studs are attached to the slab by thermally non-conductive connectors imbedded in the slab and joined to the reinforcing channels or studs to create an energy efficient light weight and durable panel. An insulation layer may be placed between the channels or studs and the concrete slab. The space between the reinforcing channels or studs may also be filled with insulating material.

摘要： A prefabricated fireplace comprises a firebox and flue enclosed by concrete cast as a unit. The firebox has inner walls defining a fuel box in which combustion occurs and outer walls which define a circulation space around the fuel box for room air to be heated. The fuel box is sealed from the room by glass doors which open to supply fuel and, when closed, allow light and heat to pass, and oxygen reaches the fire through an outdoor duct. The prefabricated fireplace has around its base edges a plurality of weldplates which allow quick installation by welding to metal base plates cast in the foundation. The prefabricated fireplace may also include means to interface with home forced-air and water heating systems for heating of air and water.
