摘要:
Provided by the present invention is a device to reinforce the cross section of a column or beam having two or more surfaces. The device, which is formed with a ferroconcrete structure and reinforces a column having a polygon cross section, reinforces a column or a beam by adding a binding force which acts in the central direction of a cross section, which is at right angle to the column, by tension which is applied on a wire rod which is in contact with a wire rod support part arranged at each edge of the column by including: multiple wire rod support parts which are arranged at every edge part where a plane part of the column meets another different adjacent plane part mutually; and an external force applying part which adds the tension of a predetermined strength to the wire rod by having a different wire rod applying part installed in a different plane part in order to connect a fixing anchor or a wire rod tension part installed on the plane part with one end of the wire rod connected with the other end.

The present invention relates to a method for repairing and reinforcing a cross section of a concrete structure. A ratchet wheel anchor bolt is installed on both ends of a chipped part after chipping a concrete surface when the cross section of the concrete structure is repaired and reinforced. After an aramid fiber is anchored on the head of the ratchet wheel anchor bolt, a ratchet wheel is rotated in order to apply a tensile force to the aramid fiber. Therefore, the present invention maintains repairing and reinforcing effects in a long term by improving durability, chemical stability, and physical properties such as tensile strength and compression strength.

PURPOSE: A repair and reinforcement method of a concrete structure cross section is provided to maintain repair and reinforcement effects for long time by completely blocking the input of moisture and oxygen and to improve the repair and reinforcement effect by reinforcing water resistance, weather resistance, and surface hardness. CONSTITUTION: A repair and reinforcement method of a concrete structure cross section comprises as follows. The concrete structure cross section on which repair and reinforcement are needed is chipped and is trimmed out when a part which is not damaged comes out. A mortar composite is coated on the trimmed concrete cross section. Primer is coated on the surface on which the mortar composite is coated. A paint composite is coated on the surface on which the primer is coated.

PURPOSE: An antifungal organic/inorganic hybrid impregnation-type reinforcing agent composition is provided to enhance water-tightness, water resistance, chemical resistance, abrasion resistance, durability, intensity, and antibacterial of the concrete. CONSTITUTION: An antifungal organic/inorganic hybrid impregnation-type reinforcing agent comprises 5-50 weight% of potassium silicate, 2-30 weight% of aqueous acrylic emulsion, 0.1-5 weight% of organic binder, 1-10 weight% of water repellent, 0.1-10 weight% of antiseptic, and 0.1-10 weight% of water. The potassium silicate has a molar ration of SiO2 to K2O is 1:2.8-1:3.4. A solid content is 35-45 weight% and pH is 10-12. The aqueous acrylic emulsion has a non-volatile matter of 40 weight% or greater. The organic binder includes resins selected from epoxy resin, acrylic resin, polydimethylsiloxane resin, phetol resin, polyurethane resin, amino resin, and polyester resin.
