[Case Study] Automotive Parts Manufacturing <Modification of Duct Inspection Port>

Modified inspection port for internal checks without tools! A case where work time was significantly reduced.

We would like to introduce a case of modification of a duct inspection port in automotive parts manufacturing. The task of inspecting and cleaning the duct from the inspection port occurred frequently, and it was cumbersome to remove bolts and nuts each time. After the implementation, we were able to open and close the inspection port with a handle that requires no tools, significantly reducing the work time. [Case Overview] ■ Background of Implementation - The task of inspecting and cleaning the duct from the inspection port occurred frequently. - It was cumbersome to remove bolts and nuts each time. ■ Improvement Details - The inspection port can now be opened and closed with a handle that requires no tools. - We were able to significantly reduce the work time. *For more details, please refer to the PDF document or feel free to contact us.

Fireproof and high airtight ceiling inspection opening [45-minute semi-fireproof structure compatible product]

Fireproof and high airtight ceiling inspection opening [45-minute semi-fireproof structure compatible product]

Ceiling inspection openings with a 45-minute semi-fire-resistant structure that do not pose fire safety issues even when installed on fireproof covering lines [Special column now available].

■Ensuring the Continuity of Fireproof Coating The fireproof performance of our conventional products (made of aluminum) is approximately 28 minutes (according to our test values), which may not ensure the continuity of fireproof coating in quasi-fireproof structures or reinforced ceilings. By using a fireproof ceiling inspection opening, continuity of the fireproof coating can be ensured. ■Simplification of Construction To ensure the continuity of fireproof coating, there are cases where various methods are employed, such as providing a site-manufactured box-shaped fireproof coating above the ceiling inspection opening. However, the measures for fireproof coating have become a burden on the site. This product eliminates the need for a box-shaped fireproof coating, leading to a reduction in on-site construction effort. ■Ensuring High Airtightness By providing a recess to maintain the elasticity of the airtight material. It has high airtight performance equivalent to JIS A 4706 (sash) airtightness grade A4 (according to our test values). ■Special Column Published by Noboru Yasui, Representative of Sakura Design Group First-Class Architect Office "What are the precautions for fireproof coating required in quasi-fireproof and fireproof buildings?" ↓Click the related link↓

Fire-resistant and airtight ceiling inspection opening [60-minute semi-fire-resistant structure, compatible with reinforced ceilings]

Fire-resistant and airtight ceiling inspection opening [60-minute semi-fire-resistant structure, compatible with reinforced ceilings]

Ceiling inspection openings compatible with 60-minute semi-fire-resistant structures and reinforced ceilings that do not pose fire safety issues even when installed on fireproof covering lines [Special column now available].

■Ensuring the Continuity of Fireproof Coating The fireproof performance of our conventional products (made of aluminum) is approximately 28 minutes (based on our test values), so it is conceivable that continuity of fireproof coating cannot be ensured in quasi-fireproof structures or reinforced ceilings. By using fireproof ceiling inspection openings, continuity of fireproof coating can be secured. ■Simplification of Construction To ensure the continuity of fireproof coating, there are cases where various methods are employed, such as installing a site-manufactured box-shaped fireproof coating above the ceiling inspection opening; however, these measures can become a burden on the site. This product eliminates the need for a box-shaped fireproof coating, leading to a reduction in on-site construction effort. ■Slimming Down the Visible Width for Aesthetic Appeal Compared to products that comply with 45-minute quasi-fireproof structures, the visible width has been narrowed, and the base material has been painted for a cleaner appearance. ■Consideration for Safety During Opening, Closing, and Inspections Since ceiling materials become heavier in 60-minute quasi-fireproof structures or reinforced ceilings, a fall prevention chain is standardly equipped to prevent the lid from opening too forcefully during inspections. ■Special Column Published by Mr. Noboru Yasui, Representative of Sakura Design Group, First-Class Architect Office "What are the important points regarding fireproof coating required for quasi-fireproof and fireproof buildings?" ↓Click the related link↓
