A folding linkage is hereby disclosed that is comprised of four links, each link having a bevel gear on its end, where each link is in geared contact with a neighboring link, such that both links are held together by a hub element that is small relative to the two links. An alternate embodiment of the invention has links that have a spur gear on each end, whereby each gear end is engaged with a central rack (linear gear).

A prefabricated form assembly for making a concrete floor is disclosed. The form comprises an elongated form plate having a front for forming and retaining a flowable concrete material before it sets, anchor elements extending from the back face of the form plate, and being destined to be embedded into the concrete floor; and an L-shaped lintel having a back wall connected to the front face of the form plate and a bearing wall for supporting a masonry wall. Advantageously the construction of a concrete floor adapted to structurally retain a masonry wall using prefabricated form assemblies according to the invention no more requires the use of different groups of workers from different building trades as in the prior art, only one group of workers is required.

The present invention provides building materials and methods for the manufacturer which includes an extrudable thermoplastic or thermosetting substrate having a fluorocarbon-based capstock layer applied to the substrate. The fluorocarbon-based capstock layer can further include one or more top coats for providing a variegated, colored or textured pattern. The capstock layer, with or without the top coats, preferably has a thickness less than 4 mil and contains a UV-resistant PVDF resin.

Collapsible support structures and methods of making collapsible support structures which interconvert between a deployed condition and a collapsed planate condition which allows extensible retractable deployment of the collapsed structure from a reduced volume rolled condition.

A wall system, head joint drainage device and method adapted to allow drainage of moisture from a head joint of a structure meeting a horizontal interruption when the wall system is formed with a plurality of building products set with mortar forming a mortar joint between adjacent ones of the plurality of modular building products. A spacer has a top portion, having a length approximately equal to a depth of the plurality of building products and a width approximately equal to a width of the mortar joint, adapted to block the mortar from reaching the horizontal interruption and has a side portion adapted to keep the portion a distance away from the horizontal interruption, the distance allowing moisture drainage from the head joint.

A cooling tower structure and method of construction using multiples of standard concrete masonry units (CMUs) properly reinforced, using standard CMU construction methods and specifications, and using block masons of ordinary skill, costing less for construction and maintenance, requiring less heavy equipment, less transportation and lifting of heavy and large components, a smaller construction work site, and requiring significantly less time to construct and make operational.

A kit for framing a doorway, window, or passageway in a wall of a building includes a king stud having a channel formed along its length on one side. A jack stud includes a raised strip that is formed along its length, the raised strip fitting into the channel of the king stud to form a beam. A beam is provided on each side of the doorway, window, or passageway. A header extends across the top of the doorway. The header includes end projections that extend into the channels of the king studs and that rest on top of the jack studs of the beams. Brackets may be provided at the bottom of the beam to connect the beam to a bottom plate of a wall frame. A window sill plate extends between and into the king studs for window openings.

Structural support systems and methods are provided to reinforce lintel support systems. According to some embodiments, a reinforcement system to reinforce an elongated load bearing member having opposing ends and supporting a load can comprise an elongated reinforcing member having a first portion and a second portion. The first portion can be disposed beneath the load bearing member between the opposing ends of the load supporting member and have a length substantially equal to the length of the load bearing member. The second portion can have length greater than the first portion. Also, the second portion can extend in a substantially normal direction from the first portion and be spaced apart from the load bearing member. The second portion can be securedly fixed in a substantially static position to support the first portion disposed beneath the load bearing member. In one configuration, the second portion can be fixed to a header associated with a lintel support system. Other embodiments are also claimed and described.

The invention discloses an autoclaved aerated block lintel and a construction method thereof. The construction method comprises the steps that first pre-buried components are arranged on vertical main structures on the two sides of a lintel; second pre-buried components are arranged at the bottom of a horizontal main structure on the top of the lintel; a lintel bottom bracing is fixedly mounted between the first pre-buried components arranged on the vertical main structures on the two sides of the lintel; lintel vertical bracings are fixedly mounted between the second pre-buried components and the lintel bottom bracing; the outer side of the lintel bottom bracing and the outer sides of the lintel vertical bracings are cladded by an autoclaved aerated masonry shell to form lintel bottom bracing casting space and lintel vertical bracing casting space which internally communicate with each other; concrete casting is conducted in the lintel bottom bracing casting space and the lintel vertical bracing casting space to form a lintel combination bracing; and autoclaved aerated blocks are constructed on the lintel combination bracing, and lintel construction is completed. The autoclaved aerated block lintel and the construction method thereof are applied to the construction method of an autoclaved aerated block large-span hole lintel, and have the characteristics of convenient construction and little size deviation compared with a traditional cast-in-place concrete lintel, formwork erection is omitted, and the appearance quality is improved.
