Problems solved by technology

[0006] In view of the above analysis, the present invention aims to provide a green and energy-saving large-span roof structure system and roof system to solve the problem of using horizontal skylights in the prior art to directly introduce natural light, but with the change of the sun’s altitude angle, the direct introduction will cause problems. The light intensity changes drastically with time, the illuminance distribution is extremely uneven, and a large amount of artificial lighting is required

Embodiment 1

[0054] A specific embodiment of the present invention, such as Figure 2-5 As shown, a green and energy-saving long-span roof structure system is disclosed, including:

[0055] The main structure of the roof, with a skylight installation opening on the main structure of the roof;

[0056] The skylight unit structure 6 is located at the installation opening of the skylight. The skylight unit structure 6 has a surface light end and a backlight end. The backlight end is connected to the main structure of the roof. The space between the main structure of the cover forms a light inlet for natural light.

[0057] In this embodiment, a specular reflection roof 7 is provided on the roof top surface on the light side of the light inlet, and a diffuse reflection ceiling 8 is provided on the lower surface of the skylight unit structure 6, and natural light passes through the mirror reflection roof 7 and diffuse reflection. Suspended ceiling 8 is introduced into the house.

[0058] Whe...

Embodiment 2

[0083] Another specific embodiment of the present invention discloses a green and energy-saving long-span roof structure system, which is different from Embodiment 1 in that the size of the light inlet between the skylight unit structure 6 and the roof main structure can be adjusted. Specifically, as Figure 14 As shown, the backlight end of the skylight unit structure 6 is rotatably connected to the second roof grid through a rotating connector 19, and the vertical struts 9 and the oblique struts 10 are both telescopic rod structures. By adjusting the vertical struts 9 and the oblique struts 10, and use the fixture to fix the vertical strut 9 and the oblique strut 10 at a specified length, so as to realize the adjustment of the size of the light inlet between the skylight unit structure 6 and the roof main structure.

[0084] In one of the optional embodiments, the vertical strut 9 adopts a hydraulically adjustable vertical strut 17, which includes a hydraulic cylinder, a pis...

Embodiment 3

[0088] Another specific embodiment of the present invention discloses a roof system, including the green and energy-saving large-span roof structure system of Embodiment 1 or Embodiment 2, and rainwater collection and treatment are also arranged on the top of the large-span roof structure system device and cleaning device, wherein the rainwater collection and treatment device is used to collect rainwater and filter the rainwater; the cleaning device is used to spray cleaning liquid on the top surface of the long-span roof to clean the roof The specular reflection roof 7 on the cover top surface is cleaned to ensure the specular reflection effect of the roof to natural light.

[0089] Exemplarily, multiple rainwater diversion pipes are set on the top surface of the long-span roof, and the water inlets of the rainwater diversion pipes can be set at the low-lying places on the top of the roof, and the outlets of the multiple rainwater diversion pipes converge to connect to the rai...

Abstract

The invention relates to a green energy-saving large-span roof structure system and a roof system.The roof structure system comprises a roof body structure and a skylight unit structure, and the roof body structure is provided with a skylight mounting opening for mounting the skylight unit structure; the skylight unit structure is provided with a surface light end and a backlight end, the backlight end is connected with the roof main body structure, the surface light end is obliquely upwards arranged towards the light inlet direction, and a light inlet of natural light is formed in the space between the surface light end and the roof main body structure; a specular reflection roof is arranged on the roof top face on the light inlet face side, a diffuse reflection suspended ceiling is arranged on the lower surface of the skylight unit structure, and natural light is led into a room through the specular reflection roof and the diffuse reflection suspended ceiling. Natural light can be introduced for a longer time, it is guaranteed that the light intensity change amplitude is small in most time periods in the daytime, the light sensation is soft, and supplement and replacement of artificial illumination are achieved.

Description

technical field [0001] The application belongs to the technical field of green and energy-saving buildings, and in particular relates to a green and energy-saving large-span roof structure system and a roof system. Background technique [0002] At present, new large-scale public buildings such as terminals, high-speed rail stations, exhibition halls, and gymnasiums in my country adopt large-scale planes due to functional requirements, and spatial grids are generally used as their large-span roof structure systems. The general one-way force transmission space grid structure can choose three-dimensional truss, three-dimensional arch frame, string-tensioned three-dimensional arch truss and other structural systems, and the two-way force transmission space grid structure can use grid structure, reticulated shell, string-supported two-way grid and other structures. system. Applicable to different architectural functional requirements, the above-mentioned various spatial grid str...
