摘要:
PURPOSE: A drain board for the base floor of a building is provided to facilitate to construct by assembling and arranging a drain board by pieces on the surface of a concrete foundation which consists of the lowermost floor of a building. CONSTITUTION: A drain board(10) comprises a body board(11), a side support(12), a center support(13), a side reinforcement body(14), a center reinforcement body(15), and a horizontal alignment metal pin(17). The side and center supports are integrally formed in the lower center and every lower corners of the body board and adhere to the surface of a concrete foundation(32). The side reinforcement body is integrally formed at every side in the lower surface of the body board and integrally connects each side support. The center reinforcement body is integrally and diagonally formed in the lower side of the body board and integrally connects each side and center support. The horizontal alignment metal pin is inserted into a height adjustment groove(16) formed in the lower side of the side and center supports for adjusting the horizontal state of each drain board.

PURPOSE: An inorganic ceramic painting process is provided to improve durability, salt-preventing property, and staining resistance of a construction structure or construction panel by forming an epoxy coating layer and a ceramic coating layer in order on the surface of the construction structure or construction panel. CONSTITUTION: An inorganic ceramic painting process comprises a step of removing impurities from a construction structure or construction panel, a step of forming an epoxy coating layer by spraying water-soluble epoxy mixture paint on the surface of the construction structure or construction panel, and a step of forming a ceramic coating layer by spraying ceramic paint on the epoxy coating layer. The water-soluble epoxy mixture paint comprises 15-25 weight% of epoxy resin, 0.5-2 weight% of tackifier, 0.3-2 weight% of foaming agent, 5-30 weight% of pigment, 15-25 weight% of aqueous amine curing agent, 1-5 weight% of alcohol-based solvent, and 30-40 weight% of water. The ceramic paint comprises 25-45 weight% of colloidal silica, 15-35 weight% of silane, 10-40 weight% of pigment, 10-20 weight% of isopropyl alcohol, 5-15 weight% of water, and 0.5-2 weight% of foaming agent. [Reference numerals] (AA) Treating the surface of a construction structure(Coating aggregate with guss mixed asphalt); (BB) Forming an epoxy coating layer(Aqueous epoxy paint + Silicate); (CC) Forming a ceramic coating layer(Containing colloidal silica/silane compound); (DD) Curing at room temperature;

PURPOSE: A construction method of a micro-pile is provided to transfer a high load to a micro-pile by integrating high-strength epoxy grout injected ito a core hole on the inner wall of footing concrete. CONSTITUTION: A construction method of a micro-pile is as follows. A core hole is bored in footing concrete to expose the footing ground to the outside(S1). A borehole is formed by boring the footing ground to a specific depth(S2). A micro-pile is inserted into the borehole(S3). Cement grout is injected into the borehole(S4). High-strength epoxy grout is spread on the inner wall of the footing concrete which forms the core hole(S5). The high-strength epoxy grout is injected into the core hole to cover the head of the micro-pile exposed to the outside the borehole(S6).
