Embodiment Construction

[0011] refer to figure 1 , the present invention includes double-layer roof panels 1, 2, purlins 4, and upper return beams 5 on the lower floor. The double-layer roof panels are all cast-in-place roof panels. There is a profiled steel plate bottom mold 3, and an inspection ditch 10 is set under the gutter of the roof drainage organization. The roof internal drainage pipe 9 is arranged in the inspection ditch, and the drain outlet 8 is reserved in the upper return beam of the lower floor, and emergency drainage is arranged within the direction of the roof internal drainage pipe. Ditch 11, easy to repair the roof internal drainage system, the roof internal drainage pipe is designed in the closed drainage organization gutter, the drainage organization gutter has the function of emergency drainage, and the height of the emergency drainage ditch can meet the maintenance requirements. The upper return beam 5 on the lower floor meets the requirements of smooth hydrogen discharge with...

Abstract

A double-layer waterproof and drainage system for the roof of a large-scale hydrogen exhaust factory building, including roof panels, roof beams, and purlins, characterized in that: the roof panels are double-layer roof panels, the roof beams are lower upper return beams, and the double-layer roof panels are cast on site Roof slab, the upper roof slab is poured with a roof drainage gutter, the upper roof slab is equipped with a profiled steel plate bottom form, the roof drainage gutter is a maintenance ditch, and the roof internal drainage pipe is set in the maintenance ditch, and the lower return beam Drain outlets are reserved in the interior, and emergency drainage ditches are set within the direction of the drainage pipes in the roof. The drainage pipes in the roof are designed in a closed drainage organization gutter. The beneficial effects of this structure are: 1. The double-layer roof panel structure is adopted, and the roof drainage organization gutter and the accident drainage ditch are respectively arranged on the roof panel, which can solve the problem of indoor water leakage caused by roof leakage. 2. The upper roof panel and the lower roof panel of the double-layer waterproof and drainage system are all cast-in-place roof panels, and a profiled steel plate bottom mold is installed under the upper roof panel to solve the problem of hydrogen retention.

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;...
