The metal-resin composite pipe | 05-07-2009 |
20100126616 | Connection structure of wave-shaped synthetic resin pipes, wave-shaped synthetic resin pipes used for the connection structure, and manufacturing method thereof - Provided are a connection structure for connecting corrugated synthetic resin pipes and a corrugated synthetic resin pipe used in the connection structure. The pipe is lightweight, low cost, and simply structured with a small number of components, having sufficient resistance to water and pressure, and excellent sealing performance without the use of robust material or requiring high precision, and capable of being easily connected and manufactured. A first corrugated synthetic resin pipe | 05-27-2010 |
20120219747 | PANEL WITH DECORATIVE SLATE - Disclosed is a panel with decorative slate that has the appearance of stone, is lightweight and inexpensive, is not prone to staining, and maintains a beautiful appearance over a long period. In the panel with decorative slate, a foam cement panel | 08-30-2012 |
20120231233 | DECORATIVE LIGHTWEIGHT PANEL - Provided is a decorative lightweight panel excellent in moisture resistance and dimensional stability, easy to be produced, and easy to be handled. The decorative lightweight panel includes a plate-shaped lightweight cement panel; a resin-reinforcing layer formed on one surface or both surfaces of the lightweight cement panel; and a decorative layer formed on the surface of the resin-reinforcing layer or on the surface of the lightweight cement panel. | 09-13-2012 |
20130112306 | PIPELINE REGENERATION PIPE - Disclosed is a pipeline regeneration pipe with which necessary strength can be ensured by means of the inserted regeneration pipe itself without the necessity of grouting, the regeneration pipe being characterized by being configured of an inner wound flexible resin layer | 05-09-2013 |
20130175797 | SYNTHETIC RESIN PIPE WITH JOINT AND CONNECTION STRUCTURE THEREOF - Provided is a helical corrugated synthetic resin pipe with a joint which has a simple structure with a small number of parts, achieves sufficient waterproof property and pressure resistance as well as excellent sealing properties with no need for any strong material or highly accurate production, realizes reduction in weight and reduction in cost, and is easily handled with facilitated connection operation on site. The synthetic resin pipe being characterized in that a socket portion cylindrically extended from a connected-side end portion of the helical corrugated synthetic resin pipe is provided by foaming a foamable resin and an FRP layer obtained by impregnating a synthetic resin layer with reinforcing fibers is laminated at least on an outer circumferential surface of the socket portion. | 07-11-2013 |
20140124081 | SPIRALLY WAVED SYNTHETIC RESIN CONDUIT WITH COUPLING, AND CONNECTION STRUCTURE FOR SPIRALLY WAVED SYNTHETIC RESIN CONDUIT - A spirally waved synthetic resin conduit has a coupling and a connection structure, and is configured with a small number of components, achieving sufficient water and pressure resistances, excellent sealing properties with no need for any rigid material or high accuracy, reduction in weight and cost, and easy handling with facilitated connection work on site. The spirally waved synthetic resin conduit, provided with a coupling, includes a receiver opening provided at an end of the conduit and connected to another spirally waved synthetic resin conduit. The receiver opening is formed with a foamable resin into a cylindrical shape so as to extend from the end of the spirally waved synthetic resin conduit in an axial direction of the conduit, and an FRP layer is formed by impregnating reinforcing fibers with a resin, at least on an outer peripheral surface of the formed receiver opening at a connection end. | 05-08-2014 |
