Drainage structure used for historic building gallery bridge and construction method thereof

Abstract

The invention discloses a drainage structure used for a historic building gallery bridge and a construction method thereof. The structure comprises a pre-buried plate, drainage pipes, gallery bridge floors and a gallery bridge roof. Supporting rods are arranged on the gallery bridge floors. Roof supports are arranged on the top of the supporting rods. Two drainage ditches are arranged on the tops of the roof supports. Flow guiding faces are arranged in the drainage ditches. A water collecting tank is arranged between the two drainage ditches. Water inlets are formed in the two sides of the water collecting tank. A rainwater pipe is arranged at the bottom of the water collecting tank and connected with the drainage pipes. The construction method comprises the steps that (a), a foundation structure of the historic building gallery bridge is built; (b) the drainage pipes are laid; (c), the gallery bridge roof and a historic building overall roof structure are connected in a butt joint mode; (d), a drainage system is arranged; and (e), the outer sides of the supporting rods are covered with decorative face plates. The rainwater drainage amount of the gallery bridge can be increased, and the situation that drained rainwater drifts down the interior of the gallery bridge is avoided, so that the effect of wind and rain sheltering is achieved.

Description

technical field [0001] The invention belongs to the technical field of drainage of corridor bridges of ancient buildings, and in particular relates to a drainage structure for corridor bridges of ancient buildings and a construction method thereof. Background technique [0002] Ancient Chinese buildings are mainly wooden frame structures, that is, wooden columns and beams are used to form the frame of the house. The weight of the roof and eaves is transmitted to the columns through the beam frame. [0003] Covered bridges, also known as Hongqiao, centipede bridges, etc., are bridges with a roof, which can protect the bridge, and at the same time provide shade and shelter, and provide people with rest, communication, and gathering functions. There are mainly wooden arched bridges, stone arched bridges, wooden flat covered bridges, wind and rain bridges, pavilion bridges and so on. [0004] There are various forms and styles of ancient building covered bridges across the coun...

AI Technical Summary

Problems solved by technology

At present, the drainage of the covered bridge of ancient buildings mainly depends on the direct drainage of the roof of the covered bridge. When encountering strong wind and heavy rain, the discharged rainwater will fall into the inside of the covered bridge, which will affect the function of the covered bridge as a shelter from wind and rain.
