戸田建設 List of Products and Services

"Juutenmieruka" is an ultra-thin sheet-like 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-like sensor is flexible, making it easy to adhere to uneven shapes. By arranging multiple detection units on a single sheet-like substrate, it allows for comprehensive monitoring of a wide range of pouring conditions, 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 adhere to uneven shapes ■ Significantly reduces labor for installation work ■ Monitors a wide area collectively *For more details, please refer to the PDF document or feel free to contact us.

The "Protrusion-less Lock Bolt" is a product that has reduced the protrusion from the sprayed concrete surface, which was approximately 3 cm with conventional lock bolts, to nearly zero. By using this product, it is possible to prevent issues related to the protrusion, such as restraint (cracking of the lining concrete) and damage to waterproof sheets during pouring, as well as the occurrence of voids, leading to improved concrete quality. Additionally, for tightening and removing the nuts, there are four tightening holes provided, making it easy to perform these tasks 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 tightening and removing the nuts, there are four tightening holes provided, making it easy to perform these tasks with a dedicated ratchet wrench. - In the back-smooth type tunnel lining method, the fluidity and filling ability of the filling mortar are improved. *For more details, please refer to the PDF document or feel free to contact us.

• Joints between components

The "Pair Lock Clip" is a joint fitting that securely strengthens the clip connection in a short time, preventing ceiling detachment. It consists of a single component and comes in pairs, featuring a simple mechanism that sandwiches the furring channel. By interlocking the claws with each other, it firmly engages (locks) and robustly reinforces 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, available in pairs, with a simple mechanism that sandwiches the furring channel ■ Firmly engages and robustly reinforces the joint by interlocking the claws ■ Designed for ease of installation, it clicks into place with just a push of the finger, eliminating the need for screws or bolts ■ To accommodate 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.

• Joints between components

"Silent Drop" is a granular impact sound reduction material that can reduce the impact noise from walking and jumping on upper floors simply by placing it on the ceiling. The special soundproofing granules (recycled resin processed into granules) laid in the ceiling collide and rub against each other, efficiently absorbing the vibrational energy of the ceiling board and suppressing the radiation of impact noise 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.

• Soundproofing Sheet

"Yurekan" 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] ■ Instant display of building diagnostic results in an easy-to-understand format ■ 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.

• Vibration and Sound Level Meter

"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, sends it to a cloud server via an internet connection, and calculates the building's seismic intensity within the server, determining safety by comparing it with historical damage data. Users can access this information using a PC or smartphone. 【Features】 ■ Immediate and easy-to-understand display of building diagnosis 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.

• Vibration and Sound Level Meter

The "Building Medical System (R)" is a system that can provide 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, as concerns about massive earthquakes have grown, 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.
