Abstract: A method of constructing a hollow wall structure comprising: a step (A) of constructing a grout wall mold; a step (B) of grouted a curable liquid material into the grouting space; a step (C) of removing the first template wall and the second template wall so as to produce a semi-finished hollow wall having the Styrofoam board; and a step (D) of removing a semi-finished hollow wall having the Styrofoam board so as to obtain a hollow wall having a communication space. The communication space has an inflow conduit and a connection channel.

Abstract: A composite floor panel includes a frame assembly having a base plate, a plurality of first lateral supports secured to the base plate, and a plurality of second lateral supports secured to the base plate. The first lateral supports lie in a first plane and the second lateral supports lie in a second plane. The first plane and the second plane each intersect the base plate and the first plane is disposed at an angle relative to the second plane. The composite floor panel also includes a concrete portion coupled to and supported by the first lateral supports and the second lateral supports.

Abstract: A metal stud arrangement has a top track with a support rail fixed to the track-web and extending between track flanges into the trough of the track. The support rail has an enlarged hanger portion with a maximum width. A metal stud of the arrangement has an opening near the top end of the stud web for receiving the support rail, the opening having an entry passage with a width that is smaller than the maximum width of the hanger portion and the passage being adapted to receive the support rail. The opening includes an enlarged portion that is larger than the maximum width so that with the hanger portion in the enlarged portion of the opening, the stud hangs from the top track.

Abstract: The invention provides energy-saving housing wherein the indoor temperature condition can be made comfortable throughout the year by a small amount of energy by suppressing loads on cooling and heating devices, and high airtightness and high heat insulation performance can be maintained for a long period of time so that durability is excellent. The energy-saving housing includes wall parts provided with inner walling made from an inorganic material and heat insulators made from an organic foamed material, a ceiling part provided with inner walling made from an inorganic material, heat insulators made from an organic foamed material at the ceiling part or roof part, and a floor heating device provided at least at the floor part of the lower floor, and has an equivalent clearance area of from 0.3 cm2/m2 to 0.6 cm2/m2.

Abstract: A demountable modular floor for watertight raised decks consisting of a plurality of modularly assemblable composite slabs made of steel sheet and concrete, provided with a drainage system for collecting and conveying the rainwater between the slabs, wherein each composite slab comprises a bottom element (1) made of corrugated metal sheet surrounded by four suitably shaped metal sections (2, 3) and filled with a concrete layer (14), as well as four segments of upwardly open gutters (6, 7) peripherally arranged around said composite slab. The structure is completed by grid elements (8) covering the gutters (6) of larger width. The floor structure allows a rapid setting up of the raised deck and, at the same time, it affords the total dismantling thereof and prevents any seepage or leakage of water towards the underlying area.

Abstract: An improved steel and concrete floor system in which a corrugated steel deck is supported on shelves fixed to the sides of parallel spaced joists. Each joist has a top chord forming a shear connector to cause composite action to occur between the joist and a slab poured on the deck, in which the topchord is embedded. The deck acts as a form for pouring the slab, and is a permanent part of the composite floor system. The deck is fixed to the shelves either by spaced self-tapping screws or by spot welds. In the nonconcreted stage the deck and joists form a stable structure on which construction loads are safely supported.

Abstract: The composite structures are composed of wooden members such as girders of laminated wooden boards and members of reinforced concrete such as a plate of reinforced concrete which form for instance a composite load supporting structure designed as pedestrian walkway or similar structure. In order to interconnect the members of wood themselves or to members made of reinforced concrete fitted set bolts or fitted screw bolts, respectively, are arranged in such a manner that they extend through the cross sections of the wooden members and are anchored at least in one cross section of reinforced concrete. The parts consisting of reinforced concrete are poured as a rule after the assembling of the wooden structure such that deviations of dimensions can be equalized or taken up, respectively, quite easily. This allows a combining of the advantages of wooden structures and of structures made of reinforced concrete.
