Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sunshade film installation, and specifically relates to an installation structure of sunshade film and steel beam. Background Technology
[0002] Steel structure shading membrane (usually referring to shading membrane used in steel structure buildings or facilities) is a shading system that combines a high-strength support structure with a functional film. It is mainly used in large-span spaces such as industrial plants, stadiums, parking lots, and outdoor plazas.
[0003] The main function of the shading film is to reflect solar radiation. The special coating on the surface of the film (such as PVDF and nano-ceramics) can reflect more than 80% of infrared and ultraviolet rays, which can significantly reduce the internal temperature of the steel structure (10-20℃ lower than the environment without the film).
[0004] Currently, the existing technology can be referenced from patent CN208884815U, which discloses a novel shading film ceiling structure in which the shading film is directly fixed to a steel beam. However, in actual installation, directly fixing the shading film to the steel beam results in long working hours at height, high construction difficulty, and low efficiency. Utility Model Content
[0005] This utility model provides an installation structure for a sunshade film and a steel beam to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an installation structure for a sunshade film and a steel beam, comprising a steel beam, a first adapter plate, a bending screw, a second adapter plate, a sunshade film frame, and a sunshade film. The first adapter plate is welded to the top of the inner side of the steel beam and is in the same direction as the top plate of the steel beam. The bending screw is fixed to the first adapter plate by a nut. The bottom of the bending screw bends and is connected to the second adapter plate along the vertical direction by a nut. The second adapter plate is welded to the top of the sunshade film frame. The sunshade film is located at the bottom of the sunshade film frame and wraps around to the top of the sunshade film frame and is fixed to the top of the sunshade film frame by screws.
[0007] By adopting the above technical solution, a first adapter plate is welded onto the steel beam, and a second adapter plate is welded onto the sunshade film frame. The first adapter plate and the second adapter plate are connected using bending screws. The sunshade film is pre-fixed to the sunshade film frame. Therefore, the fixing of the sunshade film can be completed on the ground. For high-altitude operations, it is only necessary to connect the first adapter plate and the second adapter plate with bending screws. Compared with fixing the entire sunshade film to the steel beam for high-altitude operations, this greatly reduces the time spent on high-altitude operations and improves construction efficiency.
[0008] Preferably, the bending screw bends toward one side of the steel beam.
[0009] By adopting the above technical solution, the sunshade film frame can be located below the steel beam, thus resulting in a larger distribution area of the sunshade film.
[0010] Preferably, the sunshade film frame extends below the steel beam and does not exceed half the width of the steel beam.
[0011] By adopting the above technical solution, the shading membrane frame does not exceed half the width of the steel beam, thus ensuring that adjacent shading membrane frames have spacing and will not affect each other's installation.
[0012] Preferably, two nuts are provided at the top and bottom of the adapter plate one, and two nuts are provided on the outer side of the adapter plate two.
[0013] By adopting the above technical solution, the structure is firmly fixed and stable.
[0014] Preferably, the steel beams form a rectangular grid, the sunshade film frame is rectangular, and the first adapter plate, the bending screw, and the second adapter plate are each set on one of the four sides of the rectangle.
[0015] By adopting the above technical solution, the roof typically uses rectangular grid steel beams, with one beam on each of the four sides to ensure stable installation.
[0016] The beneficial effects of this utility model are as follows: a first adapter plate is welded onto the steel beam, and a second adapter plate is welded onto the sunshade film frame. The first adapter plate and the second adapter plate are connected using a bending screw. The sunshade film is fixed to the sunshade film frame in advance. Therefore, the fixing of the sunshade film can be completed on the ground. For high-altitude operations, only the first adapter plate and the second adapter plate need to be connected by the bending screw. Compared with fixing the entire sunshade film to the steel beam for high-altitude operations, this greatly reduces the time spent on high-altitude operations and improves construction efficiency.
[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of this invention may be realized and obtained by means of the methods particularly pointed out in the description.

[0021] The technical solution of this utility model will be described in detail below through embodiments. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.
[0022] Combination Figure 1 and Figure 2 An installation structure for a sunshade film and a steel beam includes a steel beam 1, a first adapter plate 2, a bending screw 3, a second adapter plate 4, a sunshade film frame 5, and a sunshade film 6. The first adapter plate 2 is welded to the top of the inner side of the steel beam 1 and is in the same direction as the top plate of the steel beam 1. The bending screw 3 is fixed to the first adapter plate 2 by a nut 7. The bottom of the bending screw 3 is bent and connected to the second adapter plate 4 along the vertical direction by a nut 8. The second adapter plate 4 is welded to the top of the sunshade film frame 5. The sunshade film 6 is located at the bottom of the sunshade film frame 5 and wraps around to the top of the sunshade film frame 5 and is fixed to the top of the sunshade film frame 5 by a screw 9.
[0023] A transition plate 1, 2, is welded onto steel beam 1, and a transition plate 2, 4, is welded onto the sunshade film frame 5. The transition plate 1, 2, and 4 are connected using a bending screw 3. The sunshade film 6 is pre-fixed onto the sunshade film frame 5. Therefore, the fixing of the sunshade film 6 can be completed on the ground. For high-altitude operations, it is only necessary to connect the transition plate 1, 2, and 4 with the bending screw 3. Compared to fixing all the sunshade film 6 to the steel beam 1 for high-altitude operations, this greatly reduces the time spent on high-altitude operations and improves construction efficiency.
[0024] The bending screw 3 bends towards one side of the steel beam 1, which allows the sunshade film frame 5 to be located below the steel beam 1, thus making the distribution area of the sunshade film 6 relatively large.
[0025] The sunshade film frame 5 extends below the steel beam 1 and does not exceed half the width of the steel beam 1. The sunshade film frame 5 does not exceed half the width of the steel beam 1, so that adjacent sunshade film frames 5 have a gap and will not affect each other's installation.
[0026] Nut 7 is provided at the top and bottom of adapter plate 2, and nut 8 is provided on the outside of adapter plate 4, which are firmly fixed and the structure is stable.
[0027] The steel beam 1 forms a rectangular grid, the sunshade film frame 5 is rectangular, and the first adapter plate 2, the bending screw 3, and the second adapter plate 4 are set on each of the four sides of the rectangle. The roof usually uses rectangular grid steel beam 1, and setting one on each of the four sides can ensure the stability of the installation.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
