Quels sont les différents types d'accès au plafond?

The different types of ceiling access are access doors, access panels, attic hatch, ceiling tiles, and pull-down stairs. Ceiling access allows service professionals to work on air conditioning or heating units. Construction workers may also need to gain ceiling access to lay insulation and repair roofing. Le câblage de l'éclairage aérien nécessite souvent des électriciens pour travailler au-dessus du plafond pour installer les ventilateurs ou l'éclairage.

Les portes d'accès sont les plus courantes dans les bâtiments commerciaux. The door may lead to boiler rooms or large scale air conditioning units that are mounted on the roof. Ceiling access to these doors is typically secured with a lock so only authorized personnel can enter. Des mesures de sécurité sont utilisées pour prévenir les blessures dans le cas où une personne est tombée.

Les panneaux d'accès sont également plus courants dans les bâtiments commerciaux que les résidences personnelles. Ceiling access via an access panel is used to enable electricians to work with fuse boxes mounted in the ceiling. Other uses for access panels are to hide ceiling sound systems and air conditioning filters. The panel is mounted in the ceiling with a metal frame, and hooks keep the panel in place. When the filter needs to be changed, the hooks are unlatched, the panel removed, and the dirty filter thrown away.

Ceiling access through an attic hatch is often found in residential buildings. Normally constructed of plywood, the access hatch is built to fit inside a wooden frame. Lorsque l'accès à la zone de plafond est nécessaire, le professionnel du service placera une échelle directement sous la trappe, monte jusqu'à ce que la trappe puisse être poussée en toute sécurité vers le haut, puis glissez la trappe sur le côté. When work is finished, the hatch is pulled back into place.

Ceiling tiles work much the same way as an attic hatch. The main difference are ceiling tiles are placed in a grid that covers the entire ceiling. Also known as drop or suspended ceilings, the ceiling tiles are lower than the main ceiling of the building. L'espace entre le plafond principal et le plafond en suspension est utilisé pour le travail des conduits de climatisation, les systèmes d'arrosage ou le câblage électrique.

Pull-down stairs are another method of ceiling access. An access hatch is built into the ceiling but instead of requiring a ladder to reach, stairs are attached to the hatch. A string dangles from the bottom side of a hinged hatch, which can be pulled to expose folded stairs. The stairs are then unfolded and placed on the ground. This method of ceiling access is mostly used for residential buildings and provides access to ceiling storage.
