专利汇可以提供Composite concrete construction of two-way slabs and flat slabs专利检索,专利查询,专利分析的服务。并且The present disclosure relates to a method and means of building two-way slabs and flat slabs, reinforced concrete floors and roofs employing composite concrete flexural construction which require little or no formwork, greatly reduce the use of temporary stringers and shores, increase the speed of construction, reduce the number of skilled workmen on the job and materially reduce the over-all cost of construction. The bottom layer of the composite concrete floor is formed by using a plurality of thin prefabricated concrete panels of considerable length and of a width in the neighborhood of around 8 feet or so, laid side by side in place on the job site with their ends resting on temporary or permanent supports. The panels are precast with one or more lattice-type girders or trusses extending lengthwise of each panel having their bottom chords firmly embedded in the panel and with the webbing and top chords extending above the top surface of the panel to afford reinforcement in a longitudinal direction from support to support. Transverse reinforcing of the panels is obtained by embedding a plurality of transversely disposed reinforcing rods or bars in the precast panels, the ends of said bars being formed with special upwardly extending return bend hooks which protrude above the upper surface of the panels along the marginal edges thereof, which are joined by the employment of a special splicing means to afford transverse reinforcement from panel to panel. The splice is completed and the transverse reinforcement obtained when the concrete topping applied on the site completely embeds the hooks, splicing link and trusses and has cured and set to form the composite concrete floor slab.,下面是Composite concrete construction of two-way slabs and flat slabs专利的具体信息内容。
