Two-layered waterproof and drainage system applied to roofs of large hydrogen discharging factory buildings

Abstract

The invention discloses a two-layered waterproof and drainage system applied to roofs of large hydrogen discharging factory buildings. The two-layered waterproof and drainage system comprises roof plates, roof beams and purlines and is characterized in that the roof plates comprise two layers of roof plates; the roof beams are lower layer upturned beams; the two layers of roof plates are on-site poured roof plates; a roof drainage structure gutter is poured on the upper layer roof plate; a pressed steel plate bottom die is arranged under the upper layer roof plate; a maintenance channel is located under the roof drainage structure gutter; a roof inner drainage pipeline is arranged in the maintenance channel; water discharging openings are formed in the lower layer upturned beams; an accident drainage channel is formed in the running direction range of the roof inner drainage pipeline; the roof inner drainage pipeline is designed in a sealed drainage structure gutter; the purlines are supported on the lower layer upturned beams; the pressed steel plate bottom die is fixed with the purlines. The structure of the two-layered waterproof and drainage system has the beneficial effects that the two-layered roof plate structure is adopted, the roof drainage structure gutter and the accident drainage channel are formed in the roof plates respectively, the problem of indoor water leakage caused by roof rain leakage can be solved, the upper layer roof plate and the lower roof plate of the two-layered waterproof and drainage system are on-site poured roof plates, and the pressed steel plate bottom die arranged under the upper layer roof plate can be used for solving the problem of retention of hydrogen gas.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a double-layer waterproof and drainage system for the roof of a large-scale hydrogen exhaust plant. Background technique [0002] The energy storage power station project is a national demonstration project. As a dispatchable energy source, energy storage can quickly handle grid energy through the rapid conversion of charging and discharging states, and achieve the goal of smoothing power output fluctuations. Large-capacity power energy storage devices are placed in the grid It can play the role of "shaving peaks and filling valleys" for the system. The house used in this project is a multi-storey reinforced concrete factory building with a roof size of 139mx149m, which is a super-large roof; because a small amount of hydrogen will be generated during the operation of indoor equipment, the small amount of hydrogen generated must be discharged in time;...
