摘要： The present invention provides a hollow floorslab formwork, a hollow floorslab structure and a construction method of hollow floorslab. The hollow floorslab structure is formed by splicing together a plurality of hollow floorslab formworks, and the hollow floorslab formworks each comprise a flat plate portion (1). A lower portion of the flat plate portion is provided with a plurality of supporting legs (4), and an outer edge of the flat plate portion is provided with a frame (2) comprising a plurality of protective plates (21, 22, 23,24). The protective plates are each provided with a reversely-fastened plate (31, 32), and adjacent hollow floorslab formworks are spliced together by fastening the reversely-fastened plates on the protective plates. The construction method comprises the following steps: a first hollow floorslab formwork is laid first; other periphery on a former hollow floorslab formwork, except the periphery provided with a reversely-fastened plate, is spliced with a latter hollow floorslab formwork, and the reversely-fastened plate of the latter hollow floorslab formwork is fastened on the protective plate of the former hollow floorslab formwork.

摘要： A construction article 12 usable in the construction of a building made of concrete. The article 12 has base and side members 32, 34 in the form of plates extending perpendicularly from each other in an L-shape configuration. Three spaced upstanding elongate members 42 are provided upstanding from the base member 32. An appropriately shaped closure member 14 is provided which closes the open ends of the elongate members 42 such that when concrete is poured thereover the members 42 leave three openings extending through the set concrete to permit fixings to extend therethrough.

摘要： Devices, systems, and methods for constructing post-tensioned concrete slabs in a new floor construction that has a reduced gap distance between the slabs. The devices, systems, and methods can improve project construction time by reducing the time delay in accessing the floor underneath the slabs due to safety and/or weather conditions.

摘要： A floor dowel sleeve has a body portion with a top wall, a bottom wall, two side walls, and an end wall that together to surround an interior cavity. The interior cavity is configured to receive a dowel plate at an opening in the body portion opposite the end wall. Spacing elements are disposed at each of the two side walls and are configured to interface with opposing edges of the dowel plate to provide a space between the dowel plate and interior surfaces of the two side walls. The spacing elements each have a pair of legs that integrally protrude from the side wall into the interior cavity and interconnect to form a spacing chamber. The spacing elements are each configured to flex into the spacing chamber upon lateral horizontal movement of the dowel plate within the interior cavity.

摘要： A modular fluid retention system and method for exemplary uses collecting and temporarily retaining fluids, for example stormwater run-off. One example of the system includes a plurality of modular retaining units which are selectively connected together to form an interior chamber volume for collecting stormwater run-off directed into the chamber volume. A plurality of modular trays are engaged with portions of the respective retention units to prevent relative movement of the retention units and eliminate, or substantially reduce, the need for porous material to be installed in and around the retention units greatly increasing the excavation void space usable for water collection and retention. In an alternate application, only a plurality of modular trays are used as the vertical support and fluid retention volume structure for the fluid retention system.

摘要： An apparatus for prestressing a concrete floor of an inclined shaft wall includes two end bearing components, a corrugated pipe, a tension bearing rod piece and two anchor heads. The tension bearing rod piece is composed of a left tension bearing rod, a right tension bearing rod, and a loading mechanism. The left tension bearing rod and the right tension bearing rod, are connected integratedly by the loading mechanism, and the tension bearing rod piece passes through the corrugated pipe. The two end bearing components are respectively arranged at the left and right ends of the tension bearing rod piece in a sleeving manner. The two anchor heads respectively lock the left and right end bearing components. Before pouring of the floor of the shaft wall, the loading apparatus is pre-buried. After the strength of floor concrete increases to certain extent, a transverse prepressing stress is applied to the floor concrete through the loading mechanism. Finally, an internal space of the loading apparatus is blocked by grouting, so as to integrate the tension bearing component, the loading apparatus and the like with the floor concrete.
