Granted: 2013-10-10
Abstract: PURPOSE: An anti-settlement type pressing plate is provided to maintain the tension of an anchor and to prevent the settlement of a pressing plate without processing pre-reinforcement or additionally tensioning the anchor after construction. CONSTITUTION: An anti-settlement type pressing plate (10) is installed with a central pipe (30) in the center of a lower plate (20). The outer circumference of the central pipe is radially joined to a reinforcing rib (21) which connects the upper surface of the lower plate to the outer circumference of the central pipe. The upper end of an anchor embedded and fixed to the ground is joined to the upper part of the central pipe to attach the lower plate to the ground. A ring-shaped penetration part (51) is protruding from the lower outside of the lower plate to the bottom. The ring-shaped penetration part is embedded into the ground to prevent the lateral deformation of the ground under the pressing plate in the construction of the pressing plate.

Abstract: The present invention relates to an organic and inorganic composite coating method for plate type ceramic particles. According to the present invention, plate type large ceramic particles are used as a coating material, but coating is smoothly performed by electrophoresis. Therefore, dense coating with high strength and high toughness can successfully be formed through a low-temperature firing process without a sintering process. The present invention comprises the following steps of mixing the plate type ceramic particles as a coating material with a dispersion medium and providing slurry; immersing a base material to be coated in the slurry; and coating the base material with the ceramic particles while putting electrodes into the slurry, applying an electric field, and moving the ceramic particles by electrophoresis. An electrophoretic polymer binding agent has a cationic or anionic functional group, so the electrophoretic polymer binding agent is moved by electrophoresis when an electric field is applied. Also, the agent surrounds the ceramic particles and is combined with the ceramic particles. At the same time, the agent is filled in the gap among the ceramic particles coated on the surface of the base material, thereby increasing bond strength and compactness of the ceramic particles of the base material. In the slurry providing step, the electrophoretic polymer binding agent is mixed with the dispersion medium.
