Large-span steel structure truss canopy structure

Abstract

This large-span steel truss canopy structure belongs to the field of truss canopy technology. It includes four truss structures and a sunshade structure. The four truss structures include steel frame structures. Sunlight can shine into the area below the device through the slots between the steel frame structures. When the temperature rises, the servo motor is activated, causing its output shaft to drive the second pulley to rotate. Due to the belt drive, the belt drives the first pulley to rotate, which in turn causes the connecting rod to drive the threaded rod to rotate. Due to the limiting rod, the three threaded blocks can move horizontally on the outer surface of the threaded rod. Since the three threaded blocks are connected to the end secondary sunshade through the rotating rod, when the threaded blocks move, the end secondary sunshade pulls the other secondary sunshade and the main sunshade to one side, adjusting them from a folded state to a horizontal state. This can block sunlight, solve the problem of internal overheating, improve environmental comfort, and also solve the pain point of traditional large-span structures where the indoor thermal environment is difficult to control due to excessive lighting.

Description

Technical Field

[0001] This invention relates to the field of truss canopy technology, specifically to a large-span steel truss canopy structure. Background Technology

[0002] A truss canopy is a large-span spatial coverage system using a steel truss structure, typically composed of steel members connected at joints. In large buildings such as the National Speed ​​Skating Oval, this structure is called a "canopy," and its core function is to provide large-span, column-free spatial coverage while also ensuring structural stability and aesthetic appeal.

[0003] Existing large-span steel truss canopies still have certain shortcomings in actual use: existing truss canopies lack retractable shading and ventilation structures, which makes it impossible for the truss to be flexibly adjusted according to weather or usage needs. They cannot effectively block sunlight when needed, nor can they be fully opened when lighting is required, resulting in insufficient adaptability. Based on the shortcomings of existing technology, this invention designs a large-span steel truss canopy structure. Summary of the Invention

[0004] This invention provides a large-span steel truss canopy structure with the advantage of a retractable shading structure at the top of the truss, solving the problem of ineffective blocking when shading is needed.

[0005] This invention provides the following technical solution: a large-span steel truss canopy structure, comprising four truss structures and a sunshade structure, wherein the four truss structures include: Four steel structural frames are connected by four connecting frames to form a whole, and the bottom of the four steel structural frames is equipped with support frames through slot frames to provide bottom support for the overall structure and improve structural stability; The shading structure includes: Two sets of support plates, one set of support plates is rotatably fitted with a threaded rod, and the other set of support plates is connected with a limit rod, and the outer surface of the threaded rod is threaded with three threaded blocks; The outer surface of the limit rod is slidably fitted with three additional threaded blocks; Three main sunshades are hinged to the slots between the four steel frame structures, and five secondary sunshades are hinged to the left side of the three main sunshades. The three leftmost secondary sunshades are connected to side plates on both sides. One side of the side plate is rotatably fitted with a rotating rod, and multiple rotating rods on both sides are connected to threaded blocks on both sides. A mounting base, located on top of one of the steel frame structures, is used to mount the component that drives the threaded rod.

[0006] As a preferred embodiment of the present invention, a connecting rod is fixedly installed at one end of the threaded rod that passes through the support plate, and a first pulley is fixedly installed at the end of the connecting rod.

[0007] As a preferred embodiment of the present invention, a servo motor is fixedly installed inside the fixed base, and a second pulley is fixedly installed at one end of the output shaft of the servo motor. A belt is sleeved on the outer surface of the second pulley, and the belt is sleeved and connected to the first pulley.

[0008] As a preferred embodiment of the present invention, the interior of the three sets of steel structure frames is provided with sliding grooves, and the top of the two sets of connecting frames is provided with fixing grooves. The three sets of sliding grooves are slidably connected to the leftmost secondary sunshade.

[0009] As a preferred embodiment of the present invention, the four steel structure frames are internally fixedly equipped with bearing frames, and the tops of the four sets of bearing frames are fixedly equipped with mounting plates by bolts, one of the mounting plates being fixedly connected to a fixed seat.

[0010] As a preferred embodiment of the present invention, the bottom of the four steel frame structures is fixedly equipped with a fall protection structure, which includes a polycarbonate plate.

[0011] As a preferred embodiment of the present invention, four protruding plates are fixedly installed on the outer surface of the polycarbonate plate, and a hanger rod is fixedly installed on the top of the four protruding plates.

[0012] As a preferred embodiment of the present invention, the ends of the four suspension rods are fixedly installed with fixing plates, and the four fixing plates are fixedly connected to the fixing grooves by bolts.

[0013] As a preferred embodiment of the present invention, support rods are fixedly installed at the bottom of the four protruding plates, the length of the four support rods is equal to that of the support frame, and sleeve plates are fixedly installed on the outer surface of the four support rods, and the four sleeve plates are fixedly connected to the support frame.

[0014] As a preferred embodiment of the present invention, it further includes a leveling structure disposed at the bottom of the four support frames. The four leveling structures include connecting seats fixed in the inner cavity of the support frames. The four connecting seats are threaded with threaded posts. The bottom of the four threaded posts is connected to a support base. The bottom of the four support bases is connected to a rubber anti-slip pad for anti-slip.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This large-span steel truss canopy structure, through its truss and shading structures, allows multiple secondary sunshades to retract to one side of the main sunshade in its normal state. At this time, the slots between the four steel frames are exposed, allowing sunlight to shine into the area below the structure through these slots. When the temperature rises, the servo motor is activated, causing its output shaft to rotate the second pulley. Due to the belt drive, the belt drives the first pulley to rotate, which in turn causes the connecting rod to rotate the threaded rod. Due to the limiting rod, the three threaded blocks can move horizontally on the outer surface of the threaded rod. Since the three threaded blocks are connected to the secondary sunshades at the ends through the rotating rod, when the threaded blocks move, the secondary sunshades at the ends pull the other secondary sunshades and the main sunshade to one side, adjusting them from a folded state to a horizontal state. This effectively blocks sunlight, solves the problem of internal overheating, improves environmental comfort, and also addresses the pain point of traditional large-span structures where excessive lighting makes it difficult to control the indoor thermal environment. 2. This large-span steel truss canopy structure, through its fall protection mechanism, involves hoisting polycarbonate panels to the bottom of the truss structure after the truss and sunshade structures are erected. At this point, the hoisting rods are located at the top of the truss structure. After the fixing plates are inserted into the fixing slots and secured with bolts, the polycarbonate panels can protect the bottom of the truss structure, preventing foreign objects from falling and injuring personnel below when the steel frame is exposed. At the same time, the polycarbonate panels, with their high light transmittance, light weight, strong impact resistance, and good heat insulation properties, can provide good protection for the device. 3. This large-span steel truss canopy structure, through the truss structure and the fall protection structure, after the truss structure and the fall protection structure are erected, is connected and fixed to the support frame through the sleeve plate. At the same time, the support rod is located at the bottom of the protruding plate. Therefore, the support frame and the support rod can support the entire truss structure, thereby improving the overall stability of the device. 4. This large-span steel truss canopy structure, through a leveling structure, allows the truss structure to be lifted and placed at the required installation location by a crane during installation. At this time, the threaded columns are manually rotated to extend different lengths from the connecting seats, solving the problem of uneven ground on the construction site causing the overall tilting of the device and uneven stress. The leveling structure achieves overall horizontal alignment of the truss, and the rubber anti-slip pads increase the friction between the device and the ground, preventing the truss from sliding due to external forces and improving overall stability.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9The large-span steel truss canopy structure includes four truss structures 1 and a sunshade structure 2. Each truss structure 1 includes a steel frame 101, with connecting frames 102 welded between them. Slot frames 105 are fixedly installed at the bottom of each of the four steel frames 101, and support frames 4 are threadedly fixed inside each slot frame 105. The sunshade structure 2 includes two sets of support plates 21, three main sunshade plates 25, and fixing seats 211. Threaded rods 22 are rotatably installed between the support plates 21 in one set, and threaded rods 22 are rotatably installed between the support plates 21 in the other set. A limiting rod 23 is fixedly installed between the three main sunshades 25 and the four steel structure frames 101. Three threaded blocks 24 are threadedly installed on the outer surface of the threaded rod 22. Three more threaded blocks 24 are slidably installed on the outer surface of the limiting rod 23. The three main sunshades 25 are hingedly connected to the slots between them. Five secondary sunshades 26 are hingedly installed on the left side of the three main sunshades 25. Side plates 27 are fixedly installed on both sides of the outer surface of the three leftmost secondary sunshades 26. Rotating rods 28 are rotatably installed on one side of the two side plates 27. Multiple rotating rods 28 on both sides are fixedly connected to the threaded blocks 24 on both sides.

[0020] Example 1 Please see Figures 6-7 A connecting rod 29 is fixedly installed at one end of the threaded rod 22 that passes through the support plate 21, and a first pulley 210 is fixedly installed at the end of the connecting rod 29. A servo motor 212 is fixedly installed inside the fixed base 211, and a second pulley 213 is fixedly installed at one end of the output shaft of the servo motor 212. A belt 214 is sleeved on the outer surface of the second pulley 213, and the belt 214 is sleeved and connected to the first pulley 210.

[0021] When the servo motor 212 is started, its output shaft drives the second pulley 213 to rotate. Due to the transmission of the belt 214, the belt 214 drives the first pulley 210 to rotate, thereby causing the connecting rod 29 to drive the threaded rod 22 to rotate. Due to the limiting rod 23, the three threaded blocks 24 can move horizontally on the outer surface of the threaded rod 22.

[0022] Example 2 Please see Figures 2-4 The three sets of steel structure frames 101 have internal sliding grooves 103, and the tops of the two sets of connecting frames 102 have fixing grooves 104. The three sets of sliding grooves 103 are slidably connected to the leftmost secondary sunshade 26. The four steel structure frames 101 have load-bearing frames 106 fixedly installed inside. The tops of the four sets of load-bearing frames 106 are fixedly installed with mounting plates 107 by bolts, and one of the mounting plates 107 is fixedly connected to the fixing seat 211.

[0023] The strength of the steel structure frame 101 can be improved by setting the support plate 107 inside the four steel structure frames 101, and the smoothness of the hinge between the secondary sunshade 26 and the main sunshade 25 can be improved by setting the secondary sunshade 26.

[0024] Example 3 Please see Figure 8 Four steel frame members 101 are fixedly mounted with fall arrestor structures 3 at their bottoms. Each fall arrestor structure 3 includes a polycarbonate plate 31. Four protruding plates 32 are fixedly mounted on the outer surface of the polycarbonate plate 31, and hanging rods 33 are fixedly mounted on the top of each of the four protruding plates 32. Fixing plates 34 are fixedly mounted on the ends of each of the four hanging rods 33, and the four fixing plates 34 are fixedly connected to the fixing grooves 104 by bolts. Support rods 35 are fixedly mounted on the bottom of each of the four protruding plates 32, and the length of each support rod 35 is equal to that of the support frame 4. Sleeve plates 36 are fixedly mounted on the outer surface of each of the four support rods 35, and the four sleeve plates 36 are fixedly connected to the support frame 4.

[0025] By suspending the polycarbonate plate 31 to the bottom of the truss structure 1, with the suspension rod 33 at the top of the truss structure 1, and inserting the fixing plate 34 into the fixing slot 104 and fixing it with bolts, the polycarbonate plate 31 can protect the bottom of the truss structure 1, preventing foreign objects from falling and injuring personnel below when the steel structure frame 101 is exposed. The sleeve plate 36 connects and fixes it to the support frame 4, and the support rod 35 is located at the bottom of the protruding plate 32. Therefore, the support frame 4 and the support rod 35 can support the entire truss structure 1, thereby improving the overall stability of the device.

[0026] Example 4 Please see Figure 1 and Figure 9 It also includes a leveling structure 5 set at the bottom of the four support frames 4. The four leveling structures 5 include a connecting seat 51 fixed in the inner cavity of the support frame 4. The four connecting seats 51 are threaded with threaded posts 52. The bottom of the four threaded posts 52 is connected to a support base 53. The bottom of the four support bases 53 is connected to a rubber anti-slip pad 54 for anti-slip.

[0027] The truss structure 1 is lifted by a crane and placed at the required installation location. At this time, the threaded column 52 is manually rotated to extend from the connecting seat 51 by different lengths, which solves the problem of uneven ground on the construction site causing the overall device to tilt and uneven force. The leveling structure 5 is used to achieve the overall horizontal alignment of the truss. The rubber anti-slip pad 54 increases the friction between the device and the ground, prevents the truss from sliding due to external forces, and improves the overall stability.

[0028] Working principle: When using a large-span steel truss canopy structure, the truss structure 1 is first lifted by a crane and placed at the required installation location. Then, the threaded column 52 is manually rotated to extend different lengths from the connecting seat 51, solving the problem of uneven ground causing overall tilting and uneven stress on the device. After the truss structure 1 and the sunshade structure 2 are erected, the polycarbonate plate 31 is hoisted to the bottom of the truss structure 1. At this point, the hoisting rod 33 is located at the top of the truss structure 1. The fixing plate 34 is inserted into the fixing groove 104 and fixed with bolts. The polycarbonate plate 31 protects the bottom of the truss structure 1, preventing foreign objects from falling and injuring personnel below when the steel frame 101 is exposed. The polycarbonate plate 31 also provides good protection due to its high light transmittance, light weight, strong impact resistance, and good thermal insulation properties. It is then connected and fixed to the support frame 4 via the sleeve plate 36, with the support rod 35 located at the bottom of the protruding plate 32. Therefore, the truss structure 1 can be supported as a whole by the support frame 4 and the support rod 35, thereby improving the overall stability of the device. Under normal conditions, multiple secondary sunshades 26 are retracted to one side of the main sunshade 25. At this time, the slots between the four steel structure frames 101 are exposed, and sunlight can shine into the lower part of the device through the slots between the steel structure frames 101. When the temperature rises, the servo motor 212 is started, causing its output shaft to drive the second pulley 213 to rotate. Due to the transmission of the belt 214, the belt 213 can rotate. 14 drives the first pulley 210 to rotate, thereby causing the connecting rod 29 to drive the threaded rod 22 to rotate. Due to the limiting rod 23, the three threaded blocks 24 can move horizontally on the outer surface of the threaded rod 22. Since the three threaded blocks 24 are connected to the end auxiliary sunshade 26 through the rotating rod 28, when the threaded blocks 24 move, the end auxiliary sunshade 26 pulls the other auxiliary sunshades 26 and the main sunshade 25 to one side, adjusting them from a folded state to a horizontal state. This can block sunlight and solve the problem of internal overheating.
