AP工法協会 List of Products and Services

The "AP Method" is a seismic reinforcement technique that uses completely premixed mortar applied through wet spraying. It allows for the production of the required amount simply by adding water and mixing on-site, making it easy to manage the mix. There is no "water leakage" due to formwork bursting, and it features crack control. Designs can be based on the same seismic diagnosis standards and renovation design guidelines as conventional concrete (RC), and it has received technical evaluation from the Japan Building Disaster Prevention Association. 【Features】 ■ Can be applied in narrow spaces where conventional concrete pouring is difficult ■ Construction can be completed in about 1/2 to 2/3 of the time compared to conventional concrete pouring ■ Reduces the amount of mixing water from the conventional 40% to 14.5%, a 65% reduction ■ Does not use wood for formwork ■ Uses a premixed material with vinyl fiber to suppress the risk of crack occurrence *For more details, please download the PDF or feel free to contact us.

• Earthquake-resistant construction method

The "AP Method" is a seismic reinforcement technique that utilizes a completely premixed mortar, which pursues the necessary performance as a seismic reinforcement material and workability as a spray application material, applied through wet spraying. It allows for design based on conventional reinforced concrete or reinforced concrete with steel frames. By incorporating high-performance reinforcement fibers (PVA fibers), it enhances crack suppression effects. 【Features】 - Since completely premixed materials are used, only water needs to be added and mixed on-site to produce the required amount, making formulation management easy and providing economic benefits. - No bleeding water occurs, allowing for construction in sites with water restrictions. - As it is a wet spraying application, dust dispersion during construction is relatively low, resulting in less site contamination. - It can be applied using a simple mortar pumping system, making it feasible for construction in narrow spaces. *For more details, please download the PDF or feel free to contact us.

• Earthquake-resistant construction method

The "SF Method" is a technique that applies the "AP Method," traditionally used for seismic reinforcement in construction, to civil engineering and repair. This method is utilized for bridge piers, ceilings, columns, and more. 【Recent Order Achievement Applications】 ■ Exterior walls (direct construction from scaffolding) with short construction periods (no formwork) ■ Reinstallation of carbon fiber reinforced walls (existing walls already reinforced) ■ Piloti reinforcement ■ Steel reinforcement ■ Construction of spiral bars, dexia keys, and anchor sections *For more details, please feel free to contact us.

• Earthquake-resistant construction method

The "AP Method" is a construction method that involves the addition of "expansions," "additional installations," and "opening closures" for the purpose of "adding load-bearing walls." This method can be designed based on the same design standards as concrete, following the RC/SRC seismic diagnosis criteria and renovation design guidelines. In the case of additional walls, no formwork is required, and construction can be carried out while the occupants are present. 【Features】 ■ High compressive strength of 48N/mm² on average ■ No formwork required for additional walls ■ Construction can be done while occupants are present ■ Designable based on the RC/SRC seismic diagnosis criteria and renovation design guidelines *For more details, please refer to the PDF materials or feel free to contact us.

• Earthquake-resistant construction method

The "AP Method" is a seismic reinforcement technique that uses a completely premixed mortar, which pursues the necessary performance as a seismic reinforcement material and workability as a material for spray application, through wet spraying. 【Two Improvement Points】 Materials: Changed the aggregate to blast furnace slag with a weight ratio of 65% sand. Construction: Reduced mixing water from 40% to 14%, a 65% reduction. On-site, it is possible to produce the required amount simply by adding water and mixing. The management of the mixture is also easy, providing economic benefits. Additionally, since it is a wet spraying method, the dust dispersion during construction is relatively low, resulting in less contamination on-site. 【Features】 ■ Construction is possible at sites with water restrictions as no bleeding water is generated. ■ Can be constructed using a simple mortar pumping system. ■ Suitable for construction in narrow spaces, construction while occupied, no formwork required, and short construction periods. ■ Incorporates high-performance reinforcement fibers (PVA fibers) to suppress cracking. *For more details, please download the PDF or contact us.
