Proposal for Pipe-in-Sleeve in Seismic-resistant High-rise Building Design
Reduction of work on the outer wall of the underground beam (underground beam sleeve) and enhancement of waterproofing performance.
With the increase in building height and seismic resistance improvements, the width of beams has been increasing. - Increased amount of rebar (main bars and stirrups) in beams - Spread of high-strength concrete - Long-period and wind sway countermeasures - Increased load on beams due to the slimming of columns (design requirements) - Improved workability (especially with high-strength concrete) As a result of these factors, recent high-rise buildings show an increase in "beam width," particularly for underground beams, which tend to be significantly thicker, with widths exceeding 1,000 mm not being uncommon. Therefore, waterproofing work for the outer circumference of cable conduits penetrating through sleeves in underground exterior wall sections (underground beams) is extremely challenging. Due to the current shortage of construction workers and skilled labor, the waterproof performance of buildings is becoming increasingly unstable. Thus, we propose the following: **Application Scenarios** - Piping work for underground beams - Sleeve penetration work for exterior walls - Pulling through FEP pipes **Benefits of Implementation** - Significant reduction in construction time - Reduced burden on workers - Stabilization of quality - Decreased risk of water leakage

■Development Concept■ "Labor-saving in Construction Sites" In modern construction projects, the aging of skilled workers and the departure of young people have led to a constant demand for balancing work efficiency and construction quality. By utilizing "prefabrication technology," we aim to solve the persistent issues at construction sites and extend the lifespan of buildings. Furthermore, we are realizing groundbreaking products that also incorporate maintenance and upkeep performance! "Improving the Waterproofing Performance of Buildings" Waterproof treatment is mandatory for the narrow gaps between the pits, underground beam sleeves, and penetrating pipes at each construction site. Following the "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" issued by the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Economy, Trade and Industry, we have launched products that ensure safe and reliable waterproofing performance! <Areas of Demand> Underground beam sleeves (underground exterior wall sections) for various construction projects <Countermeasure Types> - Flood prevention construction: Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings by the Ministry of Land, Infrastructure, Transport and Tourism / Ministry of Economy, Trade and Industry - Promotion of waterproofing: Considerations for Waterproofing of Sewer Facilities by the Ministry of Land, Infrastructure, Transport and Tourism, etc. 【Ranking of Adoption/Inquiries】 1st: Medical Facilities 2nd: Accommodation Facilities 3rd: Commercial Facilities 4th: Educational Facilities 5th: Offices (High-rise)
