Anchorage Column Fixing Method "U-Wedge Frame"

Anchorage Column Fixing Method "U-Wedge Frame"

Securely fixed with pressure and adhesive force from wedges! Anchorless girder fixation method.

The "U-Wedge Frame" is a new anchoring method that creates a significant pressing effect by arranging wedges inside the frame, allowing for fixation on the surface of the girder. Since the anchoring function can be achieved solely through work on the wedge arrangement on the girder surface, it enables frame fixation without affecting the internal structure, such as rebar in concrete structures, thus preventing a decrease in the structural capacity. Conventional anchor bolt fastening methods require drilling at the anchor installation site and associated rebar detection, but this method does not require such tasks, resulting in excellent workability and reliable cost reduction. 【Features】 ■ Can be securely fixed to the structure ■ Can be constructed with simple processing ■ Allows frame fixation without affecting the internal structure ■ No need for drilling at the anchor installation site or rebar detection ■ Excellent workability and cost reduction *For more details, please visit our website or feel free to contact us.

FC slab construction method

FC slab construction method

After the concrete hardens, it is completely integrated with the FC board, forming a strong composite slab.

We would like to introduce the "FC Panel Slab Method." This method allows for the construction of long-span slabs without the need for temporary supports. Since prestressing is introduced, long-term creep deflection is extremely minimal, and it has the characteristic of being strong against cracking. Additionally, as it becomes a composite slab, the amount of rebar and concrete is reduced compared to conventional RC slabs. 【Features】 ■ Long-span slabs can be constructed without temporary supports ■ Long-term creep deflection is extremely minimal due to the introduction of prestressing ■ Strong against cracking ■ Thin sections can be easily notched or drilled for piping using a concrete cutter ■ Has sufficient recovery strength against excessive loading *For more details, please refer to the PDF materials or feel free to contact us.

Reinforced soil method - Greenery tail arm method (Terra Trail F2 method)

Reinforced soil method - Greenery tail arm method (Terra Trail F2 method)

Harmony with nature, tranquility. Now, Hirose reflects anew.

The greening tail arm method, as its name suggests, is designed to allow for the greening of the surface of tail arm embankments. The basic principle of the method is the same as that of the tail arm method, but instead of using heavy concrete skins, it employs mesh panels and vegetation mats, making it even easier to construct. The greened embankment surface harmonizes with the surrounding environment in suburban and mountainous areas.

Seismic retrofitting method for specific ceilings: "Fail Support Method"

Seismic retrofitting method for specific ceilings: "Fail Support Method"

Seismic retrofitting methods suitable for fall prevention measures for specific ceilings.

The "Fail-Safe Support Method" is a seismic retrofitting technique specifically designed for existing ceilings, where support materials and nets are installed directly beneath the existing ceiling and connected to the structural framework to prevent the drop of suspended ceilings. Structural components integrated with the building's framework are installed around the perimeter of the ceiling, and by fastening them to a grid-like support material arranged beneath the ceiling surface, the displacement of the ceiling during an earthquake is suppressed. Additionally, a high-strength fiber material net, which is sandwiched and integrally screwed between the support material and the ceiling surface, continues to support the ceiling components in the event of a ceiling collapse, preventing them from falling. 【Features】 - Minimizes partial dismantling of the existing ceiling. - Allows for continued use of the facility during construction. - Compared to traditional methods that involve completely removing the existing ceiling and installing a new seismic ceiling, this method allows for shorter construction periods and lower costs. *For more details, please download the PDF or contact us.

Sadoshima Z Roof Hybrid Waterproofing Method

Sadoshima Z Roof Hybrid Waterproofing Method

The hybrid waterproofing method, which excels in airtightness and weather resistance, protects buildings for a long time.

The Z Roof uses galvanized steel sheets as the base material and standard molten zinc-coated steel sheets, offering superior corrosion resistance compared to other company's deck roofs. Additionally, the Yodo GL Eco Green steel sheet used as the base material has a special coating that does not contain hexavalent chromium, which is an environmentally harmful substance. The Z Roof Type 1 features a structure that conceals the screws used to secure the insulation and sheet at the joints, enhancing the aesthetic appeal from the interior side and preventing the falling of metal shavings generated when fixing the screws to the steel sheet.

Piping construction "Freeze construction method (building)" revolutionary thawing method for non-stop water freeze construction.

A groundbreaking non-flame thawing method has been developed that allows for plumbing branch and valve replacements and expansion work with minimal water drainage using a continuous water freezing method!

The "Non-Water Freezing Method" is a technique that uses liquid air (nitrogen) to freeze water inside pipes, allowing for the replacement of pipe branches and valves, as well as expansion work, with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off water supply to the entire building. After using the freezing method, it is essential to perform thawing work on the frozen areas, but a new thawing method called "DOWT" has been developed, which allows for thawing without the use of fire and in a short time! 【Features】 ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing remaining on the pipe. ■ Reduces the time required for water outage work. ■ Contributes to the longevity of pipes. ■ Can be thawed in the same time or less than using fire. * For more details, please refer to the PDF materials or feel free to contact us.

Frozen construction method for water supply and building/mansion piping renovations! Overwhelming reduction in construction time.

Frozen construction method for water supply and building/mansion piping renovations! Overwhelming reduction in construction time.

Published in the global scientific journal "Science Advances." Numerous achievements in national government offices and the private sector! Case study materials are also available!

The "freezing method (for buildings)" involves using liquid air (nitrogen) to freeze the water inside pipes, allowing for the replacement or addition of pipe branches and valves with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off the water supply to the entire building. A paper on the continuous water freezing method has been published in Science Advances, a globally recognized scientific journal. (We received assistance from Professor Yoshiyasu Muto of Keio University, Faculty of Environmental Information.) ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing behind in the pipes. ■ It can shorten the time required for water outage work. *For more details, please contact us or download the PDF.
