TL;DR: A tubular frame is made of pieces of tubing (2) made of perforated paper or plastics, interconnected with junction pieces (4), and the base (8) of the frame is embedded in a concrete screed (6).
Abstract: A tubular frame is made of pieces of tubing (2) made of perforated paper or plastics, interconnected with junction pieces (4), and the base (8) of the frame is embedded in a concrete screed (6). Perforated reinforcing sheets (10) made of paper board (or of plastics or fabric) are attached to the framework e.g. by clips, and a mould is constructed from cardboard sheets which are spaced from each other by spacers passing through reinforcements in the reinforcing sheet (10); further folded sheets are placed around apertures such as doors or windows. Through openings in the top edge of the resultant mould, light-weight concrete is poured into the mould and fills it, so that the frame therein becomes an integral part of the concrete which also flows through the perforations in the reinforcing sheet (10). Walls, ceiling and roof can all be formed at the same time. After the concrete is dry the clips which attach the moulding sheets and these sheets are removed. The exposed surfaces may be treated with a resin as a protective coating. Houses can thus be constructed, preferably by using pre-cut reinforcing sheets of modular sizes, and a house can thus be built rapidly, and the mould materials can be re-used.

TL;DR: In this paper, a rotary laser projector capable of projecting a laser beam in the horizontal direction in the vicinity of a road to be paved, and fixing laser beam receivers on two front and rear positions of the side of a screed arm was used to highly accurately detect the thickness of a pavement without modifying a vehicle.
Abstract: PURPOSE:To highly accurately detect the thickness of a pavement without modifying a vehicle by arranging a rotary laser projector capable of projecting a laser beam in the horizontal direction in the vicinity of a road to be paved, and fixing laser beam receivers on two front and rear positions of the side of a screed arm. CONSTITUTION:A laser level 1L rotating in parallel with ground surface is set up by rotating the head of the rotary laser projector 1 and detected by two laser beam photodetectors 3a, 3b fixed to the two front and rear positions of the side of the screed arm 2. Then upper and lower deviations from the level 1L to be a reference face are found out to detect the position of a distance detector 4 positioned between the front and rear photodetectors 3a, 3b and find out the position of unpaved ground surface from the reference face. Then, the traveling distance of an asphalt finisher is detected by a traveling distance meter 8 arranged on the lower part of the vehicle 7.

TL;DR: A render and screed mold board (100) as mentioned in this paper comprises a board body (10), two threaded rods (20), adjusting boards (30), a plurality of supporting rods (40), and a long supporting rod (50), wherein the board body comprises a base board (11) and hollow rectangular bulges (12) on the base board; side through grooves (13) are respectively formed on the rectangle bulges at two ends of the base boards; the adjusting boards are clamped in the side throughgrooves in a one-to-one correspondence manner.
Abstract: A render and screed mould board (100) comprises a board body (10), two threaded rods (20), adjusting boards (30), a plurality of supporting rods (40), and a long supporting rod (50), wherein the board body comprises a base board (11) and hollow rectangular bulges (12) on the base board; side through grooves (13) are respectively formed on the rectangular bulges at two ends of the base board; the adjusting boards are clamped in the side through grooves in a one-to-one correspondence manner; each adjusting board is formed by welding a round piece (31) and a nut (32) together; the edge of the round piece is exposed out of the end head of the board body and two sides of each rectangular bulge; the threaded rods with pointed heads (21) are respectively arranged at two ends of the board body, penetrate the panels (121) of the rectangular bulges, the round pieces of the adjusting boards and the base board, and are in threaded connection with the nut; and the supporting rods (40), which can be propped against the wall body, are in threaded connection with the base board. Through the adjusting boards, the distance between the base board and the wall body can be adjusted conveniently, so as to limit the screed height, and further ensure the flatness and the levelness of wall plastering and leveling. Therefore, the operational efficiency is high; and the render and screed mould board can be used in mechanized construction conveniently.

TL;DR: An expansion joint for placing between screed sections has a plastic foam inner (4) bonded on each side to plastic film outer layers (2,3) and the bottom ends of the plastic film layers extend past the bottom edge of the foam strip and are bent into L-shapes w.r.t. the joint as discussed by the authors.
Abstract: An expansion joint for placing between screed sections has a plastic foam inner (4) bonded on each side to plastic film outer layers (2,3). The bottom ends of the plastic film layers extend past the bottom edge of the foam strip and are bent into L-shapes w.r.t. the joint. The expansion joint is secured onto the base layer by self adhesive tape under the L-shaped profiles. Holes can be cut through the joint to fit over pipes and cables.
