We would like to introduce the post-construction slit work method "Non-Pick Method" for apartment buildings, office buildings, and more. 【Key Points of the Non-Pick Method】 1. Maintains building functionality during construction 2. Minimal impact on the interior from external construction 3. Achieves complete slitting with 30mm remaining on the wall structure due to technical evaluation obtained from the "General Incorporated Foundation Japan Building Disaster Prevention Association" ■ Low Vibration & Dust-Free - Achieves low vibration by using special bits, eliminating the need for chiseling work - No dust generation as all processes are wet work. ■ Construction Precision - Exceptional finish and construction precision are maintained through the development of special bits. - Minimal vibration results in almost no corner repairs needed. ■ Construction Environment - No chiseling work means no scattering of concrete debris. - No dust work, ensuring no impact on the interior of the building. *Comments from the design supervisor after construction The building's functionality is maintained, allowing users to operate in an environment that is unchanged from usual. It is an effective method for enhancing seismic performance with minimal construction cost burden. *For more details, please refer to the PDF document or feel free to contact us.

Introducing the post-construction slit work "Non-Pick Method" for apartment buildings, office buildings, and more. The angled construction allows for easy installation behind pipes without the need to remove external piping. Additionally, a compact dedicated cutting machine can be used for easy installation in narrow spaces. This method reduces the burden on residents and offices, ensuring excellent results and construction precision. 【Features】 ■ Outstanding results and construction precision ■ Reduced burden on residents and offices ■ Safe work while occupied, ensuring safe passageways ■ No chipping required, low noise, and dust-free construction ■ Thin residual type complete slit with technical evaluation obtained ■ Years of trust and proven results *For more details, please refer to the PDF materials or feel free to contact us.

• Earthquake-resistant construction method

The "Thin Residual Type Complete Slit" is a seismic reinforcement method for columns using post-installed slits. The design and construction guidelines are suitable for the design and construction of post-installed slits in secondary walls of existing RC (Reinforced Concrete) and SRC (Steel Reinforced Concrete) structures. These design and construction guidelines can also be applied to renovation work when seismic slits are not installed according to the design documents in existing buildings (including those constructed after the seismic code revision in 1981). 【Applicable Columns and Beams】 ■ The concrete compressive strength of columns and beams should be between 13.5 N/mm² and 36.0 N/mm² when designed for seismic reinforcement. ■ The cross-section size of columns should be at least 400×400 mm. ■ When applying to extremely brittle columns, it is limited to columns with a shear reinforcement ratio (pw) of 0.1% or more. *For more details, please refer to the PDF document or feel free to contact us.

The "Non-Pick Method" is a post-construction slitting process that allows for continuous and consistent construction from end drilling to groove cutting with a dedicated cutting machine (equipped with a special bit) in a single setup. It is a groundbreaking method that requires no chipping, produces low vibration and low noise, and generates minimal waste with excellent precision. This photo collection of the construction showcases examples of the "Non-Pick Method" used in a certain apartment building in Tokyo. It can be utilized as a partial slitting method that allows construction to be carried out while residents are living in the building, achieving seismic effects equivalent to those of complete slitting. We encourage you to take a look at this opportunity. 【Main Features】 ■ Continuous and consistent cutting can be achieved with a single setup of the dedicated cutting machine ■ The precision and finish of the slits are outstanding ■ Dust-free construction with low vibration and low noise, requiring no chipping ■ Drilling and cutting debris is in a slurry form (liquid mixed with sand particles), making disposal easy For more details, please contact us or download the catalog.

The "Non-Pick Method" makes previously impossible construction feasible. The "Non-Pick Method" allows for one-sided construction (partial slitting) from the exterior wall, eliminating the need to move residents, desks, chairs, equipment, and supplies, enabling construction while the building is in use! Additionally, it has obtained technical evaluation and patents from the Japan Building Disaster Prevention Association for its post-construction seismic slitting method, which has the same seismic reinforcement effect as complete slitting. 【Features】 ■ Seismic reinforcement method that does not require moving - Construction can be carried out while using the building without moving people or items! ■ High-quality slits - The finish quality and smoothness of the perforation cutting is outstanding - Fire resistance performance confirmed for 2 hours (performance test report available) ■ Significant improvement in construction environment! - Low noise, low vibration - Almost no dust dispersion (does not pollute the air around the work area) *For more details, please download the catalog or contact us.

In seismic reinforcement work for buildings, slits are constructed on the exterior walls. There are two methods for the slit construction: the conventional wall saw cutter and chipping method, and a dedicated cutting machine using special bits. In either method, noise is generated during cutting, so it is necessary to understand the characteristics of the noise produced by the method in order to preserve the surrounding environment during construction. 【Measurement Results of Maximum Noise Levels】 [Method: Renewal Slit Method, Cutting Method: Chipping] ○ Indoor Average: 102 (101) dB ○ Outdoor 5m: 95 (90) dB ○ Outdoor 7m: 83 (80) dB ○ Outdoor 30m: 70 (68) dB For more details, please contact us or download the catalog.

• Special Construction Method

The "Non-Pick Method" is a seismic reinforcement method for columns using partial slits. Construction can be carried out while residents are living in the building, providing seismic reinforcement effects equivalent to complete slits. With our specially developed cutting machine (with a special bit), continuous and consistent construction from end hole drilling to groove cutting can be achieved in one setup. Additionally, it requires no chipping, has low vibration and low noise, and produces minimal waste with excellent precision. 【Features】 ■ Continuous and consistent cutting can be performed in one setup with the dedicated cutting machine ■ The accuracy and finish of the slits are outstanding ■ No chipping required, low vibration, low noise, and dust-free construction ■ Drilling and cutting debris is in a slurry form (liquid mixed with sand particles), making disposal easy ■ The construction efficiency for cutting is approximately 3 to 5 meters per day per machine for a width of 30mm and depth of 100mm *For more details, please refer to the PDF materials or feel free to contact us.
