Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of large-span roofs, and specifically relates to a large-span roof. Background Art
[0002] The roof is the top structure of a building, which usually consists of a roof surface, a roof load-bearing structure, a thermal insulation layer or a heat insulation layer, and a ceiling, etc., including the roof surface. The roof is not only an enclosure structure of the building, but also bears the load and plays an enclosure role, and has an important impact on the overall image of the building. A large-span roof refers to a roof structure with a relatively large span, which is usually used to cover a relatively large space, such as public buildings like stadiums, exhibition halls, airports, etc. These roof structures need to have sufficient strength and stiffness to bear their own weight and external loads, and at the same time, aesthetics, durability and economy need to be considered.
[0003] Existing large-span roofs usually adopt transparent glass materials, which not only facilitate large-area daylighting inside the roof to ensure the comfort inside the house and prevent moisture, but when the weather is relatively hot, the sunlight outside will penetrate through the roof into the room, which will cause the temperature inside the house to be too high, thus affecting the people inside the house. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a large-span roof to solve the problems raised in the above background art.

[0013] Additional aspects and advantages of the present utility model will be given in part in the following description, will become apparent in part from the following description, or will be understood through the practice of the present utility model.
[0014] Beneficial effects: When the interior of the house is overheated and lighting is not required, the motor drives the threaded rod to rotate, and the limiting rail limits the limiting strip, so that the two light-shielding plates block the lighting plate at the bottom, thus achieving a light-shielding effect, and ventilation is carried out through the ventilation groove, which can effectively prevent the interior of the house from overheating. Conversely, when it is opened, when ventilation is not required, the baffle closes the top of the ventilation groove, and when it is closed, the sealing rubber strip is attached to the sealing groove, so that the top of the ventilation groove achieves a sealing effect, thus avoiding the situation of rain leakage and air leakage.

Detailed implementation mode
[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0023] Please refer to Figures 1-4 , a large-span roof of the present invention includes a roof body 1. The roof body 1 is the roof surface of the large-span roof and is used for installing other structures. A lighting panel 11 is arranged inside the upper part of the roof body 1. The lighting panel 11 is made of transparent glass material, which is convenient for lighting inside the house. An installation groove 12 is arranged at the bottom of the lighting panel 11. The installation groove 12 is an installation structure for installing other structures. Ventilation grooves 13 are arranged on both sides above the roof body 1. The ventilation grooves 13 are ventilation structures, which are convenient for ventilation inside the house. A blocking net 14 is arranged at the top inside the ventilation grooves 13. The blocking net 14 is a blocking structure. When ventilation is carried out in the ventilation grooves 13, impurities outside the house are blocked by the blocking net 14.
[0024] A blocking mechanism is arranged inside the installation groove 12. The blocking mechanism is used to block the daylighting board 11. When the interior of the house is overheated or daylighting is not required, the daylighting board 11 is closed through the blocking mechanism. The blocking mechanism includes two light-shielding plates 2. The light-shielding plate 2 is the main structure of the blocking mechanism, that is, the daylighting board 11 is blocked by the two side light-shielding plates 2. A threaded pipe 21 is arranged inside the light-shielding plate 2, and a threaded rod 23 is arranged inside the installation groove 12. The threaded rod 23 is threadedly connected to the threaded pipe 21. A limiting ring 24 is arranged inside the threaded rod 23. The thread directions on both sides of the limiting ring 24 are opposite, and the two threaded pipes 21 are located at the limiting ring 24. Thus, when the threaded rod 23 rotates, the two threaded pipes 21 drive the two light-shielding plates 2 to slide towards each other, and the limiting ring 24 also has a limiting effect on the threaded pipe 21. A motor 3 is arranged on one side of the threaded rod 23. The drive shaft of the motor 3 is connected to the threaded rod 23. Limiting rails 32 are arranged on both sides inside the installation groove 12. Limiting strips 22 are arranged on both sides of the light-shielding plate 2. The limiting strips 22 are slidably connected to the limiting rails 32. That is, the motor 3 drives the threaded rod 23 to rotate, and the limiting rails 32 limit the limiting strips 22, so that the two light-shielding plates 2 block the daylighting board 11 at the bottom, and vice versa for opening. Support strips 31 are arranged on both sides at the bottom of the installation groove 12. The support strips 31 are support structures, that is, used to support the two light-shielding plates 2, so that the light-shielding plates 2 are kept stable.
[0025] A baffle 4 is arranged above the ventilation groove 13. Installation openings 43 are arranged on both sides of the ventilation groove 13. The installation openings 43 are installation structures. An electric push rod 44 is arranged inside the installation opening 43. The electric push rod 44 is connected to the baffle 4. That is, the electric push rod 44 drives the baffle 4 to expand and contract. Thus, when ventilation is not required, the baffle 4 closes the top of the ventilation groove 13. A sealing groove 41 is arranged on the outer side of the top of the ventilation groove 13. A sealing rubber strip 42 is arranged at the bottom of the baffle 4. When the baffle 4 closes the ventilation groove 13, the sealing rubber strip 42 adheres to the sealing groove 41, so that the top of the ventilation groove 13 has a sealing effect, thus avoiding the situation of rain leakage and air leakage.
[0026] The working principle of the present utility model is as follows: For this large-span roof, daylighting is facilitated inside the house through the daylighting panel 11, and ventilation is facilitated inside the house through the ventilation slots 13. When ventilation is carried out through the ventilation slots 13, impurities outside the house are blocked by the blocking net 14. When the inside of the house is overheated and daylighting is not required, the motor 3 drives the threaded rod 23 to rotate, and the limit rail 32 limits the limit strip 22, so that the two side light-shielding plates 2 block the daylighting panel 11 at the bottom. The support bars 31 support the two side light-shielding plates 2, so that the light-shielding plates 2 are kept stable, thus achieving a light-shielding effect, and ventilation is carried out through the ventilation slots 13, which can effectively prevent the inside of the house from overheating. Conversely, when opening, when ventilation is not required, the baffle 4 closes the top of the ventilation slots 13, and when closing, the sealing rubber strip 42 adheres to the sealing groove 41, so that the top of the ventilation slots 13 achieves a sealing effect, thus avoiding the situation of rain leakage and air leakage.
[0027] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
