戸田建設 List of Products and Services

"Juuten Mieruka" is an ultra-thin sheet-type sensor that can manage the filling condition and compaction degree of concrete in real time. With a thickness of 0.6mm, it achieves an ultra-thin design that results in almost no cross-sectional loss of concrete. The sheet-type sensor is flexible, making it easy to attach to uneven surfaces. By arranging multiple detection units on a single sheet substrate, it can monitor a wide range of pouring conditions collectively, significantly improving monitoring accuracy compared to conventional methods. [Features] ■ Achieves an ultra-thin thickness of 0.6mm ■ Almost no cross-sectional loss of concrete ■ Easy to attach to uneven surfaces ■ Greatly reduces labor for installation work ■ Monitors a wide area collectively *For more details, please refer to the PDF materials or feel free to contact us.

The "Protrusion-less Lock Bolt" is a product that has reduced the protruding part, which was approximately 3 cm from the sprayed concrete surface in conventional lock bolts, to nearly zero. By using this product, it is possible to prevent issues related to the protruding part in the construction of the lining concrete, such as restraint (cracking of the lining concrete) suppression and damage to waterproof sheets during pouring, as well as the occurrence of voids, leading to improved concrete quality. Additionally, for the tightening and removal of the nut, four tightening holes are provided, allowing for easy implementation with a dedicated ratchet wrench. 【Features】 ■ The washer is circular and has beveled edges, preventing damage to the waterproof sheet from corners. ■ Installation of the lock bolt cover, which was previously necessary, is no longer required. ■ For the tightening and removal of the nut, four tightening holes are provided, allowing for easy implementation with a dedicated ratchet wrench. ■ In the smooth-back type tunnel lining method, the fluidity and fillability of the filling mortar are improved. *For more details, please refer to the PDF document or feel free to contact us.

The "Pair Lock Clip" is a joint fitting that securely strengthens the clip joint in a short time and prevents ceiling detachment. It consists of a single component, comes in pairs, and features a simple mechanism that sandwiches the furring channel. By hooking onto each other, they interlock firmly (lock) and robustly reinforce the joint. To accommodate various properties, we offer two types: one for new constructions and one for existing properties. 【Features】 ■ Composed of a single component, comes in pairs, and has a simple mechanism that sandwiches the furring channel ■ Interlocking by hooking onto each other, providing strong reinforcement for the joint ■ Designed for ease of installation, it clicks into place with just a push from your finger, eliminating the need for screws or bolts ■ To cater to various properties, we provide two types: one for new constructions and one for existing properties ■ By aligning with horizontal fittings, it also meets standards (tested by a third-party organization) *For more details, please refer to the PDF document or feel free to contact us.

"Silent Drop" is a granular floor impact sound reduction material that can reduce the walking and jumping noise from the upper floor simply by placing it on the ceiling. The special soundproofing granules (recycled resin processed into granules) installed in the ceiling collide and rub against each other, efficiently absorbing the vibrational energy of the ceiling board and suppressing the radiation of impact sound from the ceiling. Since it does not involve thickening the concrete floor slab, it is also effective for noise control in renovation work and can be installed from the lower floor side, where soundproofing performance is actually desired, rather than from the upper floor side that generates noise. 【Features】 ■ Simple installation method ■ Effective for renovation work ■ Installation from the lower floor *For more details, please refer to the PDF document or feel free to contact us.

"Yurekanchi" is an earthquake monitoring system that instantly assesses the structural integrity of a building when it detects shaking and displays the results on an easy-to-understand diagnostic screen. All data analysis and processing are conducted on a cloud server, allowing building seismic intensity and integrity information to be received regardless of the device or location. Additionally, information from multiple buildings can be obtained centrally. 【Features】 ■ Immediate and easy-to-understand display of building diagnostic results ■ No difficult technical terms or numbers are used; the degree of damage is represented by color ■ Easy integration with PCs and smartphones ■ Anyone can understand the condition of the building anytime, anywhere ■ The status of multiple locations can be managed collectively ■ Useful for early consideration of supply chain management during disasters *For more details, please refer to the PDF document or feel free to contact us.

"Yurekanchi" is a system that utilizes the original "Yurekanchi Sensor" from Toda Corporation to measure the shaking of buildings during earthquakes and assess their structural integrity. The "Yurekanchi Sensor" detects the movement of buildings during an earthquake as acceleration data, which is then sent to a cloud server via an internet connection. The server calculates the seismic intensity of the building and determines its safety by comparing it with historical damage data. Users can access this information using a PC or smartphone. 【Features】 ■ Instant display of building diagnosis results in an easy-to-understand manner ■ No difficult technical terms or numbers are used; the degree of damage is represented by color ■ Easy integration with PCs and smartphones ■ Anyone can understand the condition of the building anytime, anywhere ■ The status of multiple locations can be managed collectively ■ Useful for early consideration of supply chain management during disasters *For more details, please refer to the PDF document or feel free to contact us.

The "Building Medical System (R)" is a system that provides easy-to-understand diagnostic results regarding the integrity of a building just a few minutes after it has experienced significant shaking due to an earthquake. After the shaking subsides, it allows for the confirmation of diagnostic results without waiting for an expert's assessment, helping to determine whether it is safe to remain in the building. In recent years, with concerns about the occurrence of massive earthquakes, it has been implemented primarily in high-rise office buildings and condominiums. 【Benefits】 ■ Real-time knowledge of the extent of building damage ■ Effective as a BCP support tool ■ Combination of various delivery methods and customizable information content is possible ■ Capable of responding to aftershocks ■ No need for regular inspections ■ Detailed diagnostics are also possible *For more details, please download the PDF or contact us.
