摘要： A method of constructing a reinforced concrete floor structure or wall structure, including: fabricating a precast panel substantially from concrete including a first set of parallel conduits extending through the panel, wherein the conduits open to opposite sides of the panel; moving the panel into its final position on a building site; and inserting tensioning cables through the conduits and tensioning the precast panel in the direction of the conduits to form a reinforced floor structure or wall structure, and a dowel connecting system for joining adjacent precast building panels, the system comprising elongated hollow dowel members cast in at the edges of two or more precast building panels such that when the building panels are positioned adjacent to each other their respective dowel members are co-linearly aligned; and a dowel piece to be inserted into a recess of the co-linearly aligned dowel members and to extend across the building panels, wherein the recess of the dowel members is adapted to be filled with grout to anchor the dowel piece therein and thereby structurally joining adjacent building panels.

摘要： A concrete surface with a cold joint, dowel slip system and method for forming that surface are provided. Baseplates having tubular projections are fastened to at least one first form using fasteners extending part way into the first form, with the first form forming part of a periphery of a first concrete slab. When the first form is removed, the baseplates, projections and fasteners remain embedded in the first concrete slab. Slip dowels are inserted into the tubular projections and a second concrete is poured adjoining the first concrete slab, with the second concrete embedding the slip dowels, backplates and projecting distal ends of the fasteners and forming a cold joint.

摘要： A snap joint for securing construction modules together on a modular construction site, the snap joint comprising a male member mounted on a first construction module and a female member mounted on a second construction module. The female member housing locking members, a tumbler and biasing members biasing the locking members against the tumbler. The male member having shaft engageable within the female member, through a base stop of the tumbler, along a trigger path in a manner to push the tumbler out of interference with the locking members, thereby freeing the locking members to transversally engage with the shaft.

摘要： The present invention addresses the problem of providing a joint structure which comprises a joint member suitable for a butterfly joint, and a building. The joint structure according to the present invention includes a first wood panel, a second wood panel, and a butterfly wedge-shaped joint member for joining the first wood panel and the second wood panel. The joint structure has an allowable yield strength of about 10 kN or more. In one embodiment, the ratio of the bending strength of the wood panels to the bending strength of the joint member in the joint structure is 1:2.2 to 1:3.6. In addition, the joint structure according to the present invention may further include a joint member comprising laminated wood in which a plurality of plate materials are laminated.

摘要： An arrangement for forming a thermally insulated wall is provided that includes two panels connected to one another by multiple connecting means, wherein each connecting means has two receiving openings. Each panel is provided with an insertion opening, and a fixing means is inserted into the receiving opening of the connecting means through the insertion opening. Each of the connecting means includes a holding means of a first kind configured to hold a horizontal reinforcing means that connects the connecting means to one another and a holding means of a second kind configured to hold a vertical reinforcing means that connects the connecting means to one another. Other aspects are described and claimed.

摘要： A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.
