Liftable umbrella-shaped water retaining device and construction method thereof

Abstract

The invention discloses a liftable umbrella-shaped water retaining device and a construction method thereof. The liftable umbrella-shaped water retaining device comprises a water retaining cover, a horizontal bracket and a lifting rod, the water retaining cover is in an umbrella shape and is composed of at least three water retaining cover units, and the adjacent water retaining cover units are connected through corner connectors. Sealing weather-proof glue is arranged at the splicing position of every two adjacent water retaining cover units. Each water retaining cover unit is composed of a sector plate, a supporting plate, a first rib plate and a second rib plate which are integrally formed. The top surface of the fan-shaped plate is a slope surface; the horizontal bracket is supported at the lower part of the water retaining cover; a cushion block is cushioned in a gap between the horizontal bracket and the water retaining cover; the three lifting rods are triangularly arranged at the bottom of the horizontal bracket at intervals; the lifting rod is an electric push rod; the upper part of the lifting rod is connected with the horizontal bracket through a top support; the lower portion of the lifting rod is sleeved with a structure fixing support. And a sealing rubber strip is arranged between the supporting plate and the retractable roof. The technical problem that a traditional opening and closing roof composed of three or more single units is poor in water tightness in a central intersection area in a closed state is solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a liftable umbrella-shaped water retaining device and a construction method thereof. Background technique [0002] Due to its unique shape and function, open and close roofs have been widely used in public building structures. However, when the building requires watertightness in its closed state, special design and treatment are required, especially for open and closed roofs. When the composite roof is composed of three or more single units, a circular roof is formed when the retractable roof is closed, and the movable units meet at the center of the circle. [0003] If the opening and closing roof is composed of three 120° fan-shaped units, the opening and closing mode does not use the rotation around the same vertical pivot, but uses the track to slide each unit to realize the opening and closing, and forms a circle in the closed state, in order To a...
