[0011] Including steel trusses and sunshade film;

[0012] The steel truss is designed in a rhombus shape, and a space frame is symmetrically connected inside the steel truss. Circular pipe structures are laid on the inner wall edges of the area where the steel truss and the space frame intersect.

[0013] The circular tube structure also includes a laying circular tube, with connecting circular tubes fixedly welded at equal intervals to the upper end of the outer surface of the laying circular tube, and a fixed support circular tube assembled and connected to the top end of the connecting circular tube. The upper surfaces of the steel truss and the space frame are fixedly welded to the truss pop-out base at equal intervals, and the end of the fixed support circular tube is fixedly welded to the truss pop-out base.

[0014] The laying circular tube is fixedly installed on the upper surface edge of the sunshade film.

[0015] The top of each connecting round tube is fixedly welded with an adjusting inner cross rod, and a cross groove is fixedly opened inside one end of the fixed support round tube, and the adjusting inner cross rod is movably inserted into the cross groove.

[0016] An adjusting bolt is rotatably installed inside one end of the fixed support tube. The adjusting bolt is movably screwed to the inner cross rod of the adjusting bolt, and a torsion wheel is fixedly installed at the top of the adjusting bolt.

[0017] The edges of the sunshade film are all provided with baffles, and the edges of the sunshade film are fixedly connected to the laying round pipe by self-tapping screws, and a gasket is provided between the self-tapping screws and the sunshade film.

[0018] An adjusting sleeve is fixedly welded to one end of the laying circular pipe. The adjusting sleeve is inserted into the interior of the adjacent laying circular pipe. A through groove is formed on the surface of the adjusting sleeve, penetrating the outer wall of the adjusting sleeve.

[0019] A gear shaft is rotatably installed inside one end of the laying circular pipe near the adjusting sleeve. The gear shaft moves through the through groove, and a torsion wheel is fixedly connected to one end of the gear shaft outside the laying circular pipe.

[0020] An internal gear is fixedly sleeved on the outer surface of the gear shaft inside the laying circular pipe, and an internal gear rod is fixedly installed on one side of the inner wall of the adjusting sleeve. The internal gear meshes with the internal gear rod.

[0021] The steel truss and the inner wall of the space frame are provided with rectangular holes at equal intervals, and the connecting round pipe is connected to the steel truss and the space frame with stabilizers.

[0022] The stabilizer also includes an empty tube, one end of which is rotatably connected to a semi-ring body one. The side of the semi-ring body one away from the empty tube is connected to a semi-ring body two by a screw. The semi-ring body one and the semi-ring body two are together sleeved on the outer surface of the connecting round tube.

[0023] The other end of the hollow tube is fixedly connected to an end tube. Both the hollow tube and the end tube have an inner cavity. A stud is movably inserted into the inner cavity. A through groove is opened inside the stud. An inner rod is fixedly installed inside both the hollow tube and the end tube. The inner rod passes through the through groove.

[0024] The width and length of the inner support plate are both smaller than the width and length of the rectangular hole, and the length of the inner support plate is greater than the width of the rectangular hole.

[0025] The technical effects achieved by this invention are as follows:

[0026] (1) In this invention, after the laying round pipe and the sunshade film are combined, they are hoisted to the installation area. Each fixed support round pipe is fixed and welded to the corresponding truss pop-out base. At this time, the installation of a sunshade film can be completed. This suspended installation method achieves no hanging parts marks at the bottom of the steel truss, solves the problem of installation marks at the bottom of the steel truss in suspended installation, and makes the overall structure more beautiful. In addition, by processing and producing spare parts in the factory and welding and assembling them on site, the operation is simple and saves construction time.

[0027] (2) In this invention, after a piece of sunshade film is hoisted, the flatness of the sunshade film is observed with the help of a level. When it is not completely horizontal, the screwdriver is used to rotate the torsion wheel in the corresponding direction, so that the adjusting inner cross rod will move up and down in a straight line inside the cross slide groove. Finally, the flatness of the sunshade film can be adjusted, which solves the problem that the flatness of the laying round pipe frame is not easy to adjust, and makes the work of adjusting the flatness of the frame more convenient.

[0028] (3) In this invention, after the laying round pipe and the sunshade film are assembled, the assembly is hoisted to the installation area. Then, the torsion wheel at one end of the laying round pipe is rotated, so that the adjusting sleeve at the end of the other laying round pipe can move inside the laying round pipe to adjust the extensibility between adjacent laying round pipes, which can fully unfold the sunshade film and avoid wrinkles in the sunshade film. In addition, the spacing between the panels can be adjusted to flexibly adjust the spacing between each sunshade film, making the overall appearance more neat and beautiful. Moreover, this adjustment method is simple and convenient to operate.

[0029] (4) In this invention, the inner support plate is tightly attached to the inner wall of the steel truss or the space frame by setting a stabilizer, thereby fixing the distance between the connecting round tube and the steel truss or the space frame, achieving the effect of fixing the connecting round tube, making the whole structure more stable, and avoiding the sunshade film being too tight, which would cause the connecting round tube to shift. In addition, this stabilizer has a simple structure and is quick and convenient to install. Attached Figure Description

[0040] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0041] A construction process for a diamond-shaped sunshade film is described below.

[0042] S1: Preliminary preparation: Prepare the main materials and a series of auxiliary materials according to the construction drawings, and prepare the relevant construction tools according to the construction plan. The high-altitude operation platform has passed the acceptance inspection, and the roof steel truss 1 has been installed and passed the inspection.

[0043] S2: Laying out and positioning: Marking out and positioning, pulling steel wires on steel truss 1, establishing a coordinate network, and based on the coordinate network, verifying and correcting the elevation and installation position dimensions of the sunshade film 3, and determining the installation position line of the truss pop-out base 207;

[0044] S3: Welded round pipe: The connection between the fixed support round pipe 202 and the steel truss 1 is made by welding. The fixed support round pipe 202 is fitted with a smaller adjustable inner cross rod 205 as a level adjuster to adjust the flatness and gap distance of the laid round pipe 201.

[0045] S4: Fixing the sunshade film 3: Use self-tapping screws 5 to fix the sunshade film 3 onto the laying round pipe 201. Use a smaller adjusting sleeve 209 inside the laying round pipe 201 as an adjuster to ensure that the board surface is taut, flat, and securely installed.

[0046] like Figure 1-8 As shown, a diamond-shaped sunshade film installation structure includes a steel truss 1 and a sunshade film 3.

[0047] Example 1:

[0048] See attached document Figure 1 and Figure 2 The steel truss 1 is set as a rhombus, and the steel truss 1 is symmetrically connected with the space frame 101 inside. The inner wall edge of the area where the steel truss 1 and the space frame 101 intersect is covered with a circular tube structure 2.

[0049] See attached document Figure 3 and Figure 5 The circular tube structure 2 also includes a laying circular tube 201. Connecting circular tubes 203 are fixedly welded at equal intervals to the upper end of the outer surface of the laying circular tube 201. Fixed support circular tubes 202 are assembled and connected to the top of the connecting circular tubes 203. The upper surfaces of the steel truss 1 and the space frame 101 are fixedly welded to the truss pop-out bases 207 at equal intervals. The end of the fixed support circular tube 202 is fixedly welded to the truss pop-out base 207. The laying circular tube 201 is fixedly set on the upper edge of the sunshade film 3. First, the sunshade film 3 and the circular tube structure 2 are fixed. The laying circular tube 201 is fixed to the upper edge of the sunshade film 3 and fixed with self-tapping screws 5. Then, the steel truss 1 and the space frame 101 are laid out and positioned to complete the welding of each truss pop-out base 207. Then, each fixed support circular tube 202 at the top of the laying circular tube 201 is fixedly welded to the corresponding truss pop-out base 207. At this time, the installation of one sunshade film 3 can be completed.

[0050] See attached document Figure 4Each edge of the sunshade film 3 is provided with a baffle strip 301. The baffle strip 301 is designed to prevent the sunshade film 3 from moving. The edge of the sunshade film 3 is fixedly connected to the laying round pipe 201 by a self-tapping screw 5. A gasket 4 is provided between the self-tapping screw 5 and the sunshade film 3. The gasket 4 is provided to reduce the compressive stress of the self-tapping screw 5 on the surface of the sunshade film 3.

[0051] The working principle of the present invention is as follows: First, the sunshade film 3 is fixed to the circular tube structure 2. The circular tube 201 is fixed to the upper surface edge of the sunshade film 3 and fixed by self-tapping screws 5. A gasket 4 is provided between the self-tapping screws 5 and the sunshade film 3. The setting of the baffle 301 just serves to prevent the sunshade film 3 from moving.

[0052] The combined structure of the laying round pipe 201 and the sunshade film 3 is transported to the construction site. After the roof steel truss 1 is inspected and accepted, the upper surface of the steel truss 1 and the space frame 101 is marked with lines to determine the installation position of the truss pop-out base 207. Then, the welding of the truss pop-out base 207 is completed. Next, the fixed support round pipes 202 at the top of the laying round pipe 201 are fixedly welded to the corresponding truss pop-out base 207. At this time, the installation of one sunshade film 3 can be completed. This suspended installation method eliminates the traces of hanging parts at the bottom of the steel truss 1, solving the problem of installation traces at the bottom of the steel truss in suspended installation, making the overall structure more aesthetically pleasing. In addition, by processing and producing the parts in the factory and welding and assembling them on site, the operation is simple and saves construction time.

[0053] Example 2:

[0054] See attached document Figure 3 The top of each connecting round tube 203 is fixedly welded with an adjusting inner cross rod 205. One end of the fixed support round tube 202 is fixedly provided with a cross groove 204. The adjusting inner cross rod 205 is movably inserted into the cross groove 204. An adjusting bolt 206 is rotatably installed inside one end of the fixed support round tube 202. The adjusting bolt 206 is movably screwed to the adjusting inner cross rod 205. A torsion wheel 208 is fixedly provided at the top of the adjusting bolt 206. By rotating the torsion wheel 208 in the corresponding direction with a screwdriver, the adjusting bolt 206 will rotate inside one end of the fixed support round tube 202. Since the adjusting bolt 206 is movably screwed to the adjusting inner cross rod 205, the adjusting inner cross rod 205 will move linearly up and down inside the cross groove 204, thereby realizing the work of adjusting the flatness of the sunshade film 3.

[0055] The working principle of this invention is as follows: After a piece of sunshade film 3 is hoisted, the flatness of the sunshade film 3 is observed with the help of a level. When it is not completely horizontal, the torsion wheel 208 in the corresponding direction is rotated with a screwdriver. At this time, the adjusting bolt 206 will rotate inside one end of the fixed support tube 202. Since the adjusting bolt 206 is movably screwed to the adjusting inner cross rod 205, the adjusting inner cross rod 205 will move up and down linearly inside the cross slide groove 204. The setting of the adjusting inner cross rod 205 and the cross slide groove 204 is to ensure the effect of linear movement of the adjusting inner cross rod 205. Finally, the flatness of the sunshade film 3 can be adjusted, solving the problem that the flatness of the laying tube 201 frame is not easy to adjust, making the work of adjusting the flatness of the frame more convenient.

[0056] Example 3:

[0057] See attached document Figure 6 An adjusting sleeve 209 is fixedly welded to one end of the laying circular pipe 201. The adjusting sleeve 209 is inserted into the interior of the adjacent laying circular pipe 201. A through groove 210 is opened on the surface of the adjusting sleeve 209, penetrating the outer wall of the adjusting sleeve 209. A gear shaft is rotatably installed inside the end of the laying circular pipe 201 near the adjusting sleeve 209. The gear shaft moves through the through groove 210, and a torsion wheel 213 is fixedly connected to one end of the gear shaft outside the laying circular pipe 201.

[0058] See attached document Figure 7 An internal gear 212 is fixedly fitted inside the laying pipe 201 on the outer surface of the gear shaft. An internal gear rod 211 is fixedly installed on one side of the inner wall of the adjusting sleeve 209. The internal gear 212 meshes with the internal gear rod 211. Then, a torsion wheel 213 at one end of the laying pipe 201 is rotated. The torsion wheel 213 drives the internal gear 212 to rotate through the gear shaft. Due to the meshing of the internal gear 212 and the internal gear rod 211, the adjusting sleeve 209 at the other end of the laying pipe 201 is driven to move in and out of the laying pipe 201, thereby adjusting the extensibility between adjacent laying pipes 201.

[0059] The working principle of this invention is as follows: After the laying round tube 201 and the sunshade film 3 are assembled, the assembly is hoisted to the installation area. Then, a torsion wheel 213 at one end of the laying round tube 201 is rotated. The torsion wheel 213 drives the internal gear 212 to rotate through the gear shaft. Due to the meshing of the internal gear 212 and the internal gear rod 211, the adjusting sleeve 209 at the end of the other laying round tube 201 is driven to move inside the laying round tube 201, thereby adjusting the extensibility between adjacent laying round tubes 201. This allows the sunshade film 3 to be fully unfolded, preventing wrinkles from appearing on the sunshade film 3. In addition, the panel spacing can be adjusted, flexibly adjusting the spacing between each sunshade film 3, making the overall appearance more neat and beautiful. Moreover, this adjustment method is simple and convenient to operate.

[0060] Example 4:

[0061] See attached document Figure 3 Rectangular holes 102 are provided at equal intervals on the inner sidewalls of the steel truss 1 and the space frame 101. Stabilizers 6 are connected between the connecting round pipe 203 and the steel truss 1 and the space frame 101.

[0062] See attached document Figure 8 The stabilizer 6 also includes an empty tube 604. One end of the empty tube 604 is rotatably connected to a semi-ring 601. The side of the semi-ring 601 away from the empty tube 604 is connected to a second semi-ring 602 by a screw 603. The first semi-ring 601 and the second semi-ring 602 are together sleeved on the outer surface of the connecting round tube 203. The other end of the empty tube 604 is fixedly connected to an end tube 605. Both the empty tube 604 and the end tube 605 have an inner cavity 606. A stud 608 is movably inserted into the inner cavity 606. The stud 608 has a through groove 609 that passes through it. Both the hollow tube 604 and the end tube 605 have an inner rod 607 fixedly installed inside. The inner rod 607 passes through the through groove 609. An adjusting nut 611 is screwed onto the outer surface of the stud 608 between the hollow tube 604 and the end tube 605. One end of the stud 608 is fixedly connected to an inner support plate 610. The width and length of the inner support plate 610 are smaller than the width and length of the rectangular hole 102, and the length of the inner support plate 610 is greater than the width of the rectangular hole 102.

[0063] The working principle of this invention is as follows: Half-ring 601 and half-ring 602 are fitted onto the outer surface of the connecting round tube 203 and fixed with screws 603. Then, the empty tube 604 is rotated, causing the empty tube 604, along with the end tube 605 and the inner support plate 610, to rotate 90 degrees together and insert them into the rectangular hole 102. Subsequently, it is rotated 90 degrees back so that the inner support plate 610 abuts against the inner wall of the steel truss 1 and the space frame 101. Next, a wrench is used to hold and rotate the adjusting nut 611. Since the stud 608 is screwed onto the adjusting nut 611, the adjusting nut... The rotation of the mother 611 will drive the stud 608 to move linearly inside the inner cavity 606. During this process, the inner rod 607 will also move linearly inside the through groove 609. Finally, the inner support plate 610 can be tightly attached to the inner wall of the steel truss 1 or the space frame 101, thereby fixing the distance between the connecting round tube 203 and the steel truss 1 or the space frame 101, achieving the effect of fixing the connecting round tube 203, making the whole structure more stable, and preventing the sunshade film 3 from being too tight and causing the connecting round tube 203 to shift. In addition, this stabilizer 6 has a simple structure and is quick and convenient to install.

[0064] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
