Hyper CLT flooring panel

Utilizing wood CLT for summer flooring measures | Hyper CLT flooring

  • NEW
  • PRODUCT

In summer construction sites, the surface temperature of the ground plates and the heat reflection can affect the working environment. In particular, steel plates tend to retain heat when exposed to sunlight, making it a challenge to implement heatstroke prevention measures and improve the site environment for workers. Hyper CLT ground plates are civil engineering materials that utilize wood CLT. As wooden ground plates, they can be used for temporary roads, access routes, heavy machinery work yards, material storage areas, and pedestrian pathways, serving as a versatile alternative to steel plates in various civil engineering sites. In actual sites, there are cases where the surface temperature can differ by about 20 degrees compared to steel plates, making them an easy-to-suggest material for reducing heat reflection and preventing heatstroke in summer. The 5×10 plate weighs approximately 230 kg, and the 5×20 plate weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which also helps reduce construction burdens. Additionally, they feature noise reduction, environmental consideration, and CO2 fixation, which are unique to wood. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," these ground plates are also easy to utilize for innovative ideas and safety measures in public works. Companies looking to improve summer site environments are encouraged to consider Hyper CLT ground plates.

HK-2

Recommended for earthquake measures for automatic doors and equipment! Seismic device HK-2.

  • NEW
  • PRODUCT

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
