Description

Technical Field

[0001] This utility model relates to the field of steel beam technology, and more specifically, to a steel beam protection device and a steel beam storage structure. Background Technology

[0002] In the field of construction and engineering, steel beams are key load-bearing components. During the various stages of production, manufacturing, transportation and installation, they are frequently hoisted and moved, and need to be placed on various supporting structures such as jigs.

[0003] However, many finished steel beams in reality are not regular geometric shapes, and their center of gravity is difficult to determine precisely. This makes the beams prone to swaying when lifted or lowered, causing them to scrape and collide with the supporting structure. Once a collision occurs, the outer surface of the steel beam is often damaged, requiring additional grinding and repair work. This not only directly increases production costs but also disrupts construction plans and extends the project cycle. At the same time, collisions can also damage the supporting structure, affecting its normal performance and even significantly shortening its service life, posing numerous hidden dangers to the project. Utility Model Content

[0004] The problem solved by this invention is to effectively reduce the risk of scraping and collision between steel beams and supporting structures such as the jig.

[0005] To solve the above problems, this utility model provides a steel beam protection device and a steel beam storage structure.

[0006] In a first aspect, this utility model provides a steel beam storage structure, including a first support structure, a second support structure, and multiple first ropes. The first support structure is used to connect to one end of the steel beam, and the second support structure is used to connect to the other end of the steel beam. The two ends of each first rope are respectively connected to the first support structure and the second support structure. Each first rope is configured to be laid in the same horizontal plane at the bottom of the steel beam and is in a stretched state, so that the steel beam is placed horizontally by the first ropes.

[0007] Optionally, the first rope extends from the portion of the first support structure located at the bottom of the steel beam to the portion of the second support structure located at the bottom of the steel beam.

[0008] Optionally, in use, the first ropes are arranged along the length of the steel beam and are evenly spaced along the width of the steel beam.

[0009] Optionally, the first support structure includes a gate, which is a U-shaped straight groove with openings at both ends. The gate is used to fit onto the protruding plate at the end of the steel beam to achieve the connection between the first support structure and one end of the steel beam.

[0010] Optionally, the first support structure further includes a plurality of first drum shafts, the axes of the plurality of first drum shafts being collinear, and one end of each first rope being wound around a corresponding first drum shaft to achieve the connection between one end of the first rope and the first support structure.

[0011] Optionally, the first support structure further includes a cylindrical body and end plates disposed at both ends of the cylindrical body; Multiple first roller shafts are disposed inside the cylinder and share a common rotating shaft, with the two ends of the rotating shaft respectively rotatably disposed on the two end plates; The side of the cylinder is recessed to form the gate, and the channel of the gate is arranged along the axial direction of the cylinder and the two ends pass through the end plate; the side of the cylinder is provided with a plurality of first rope outlets spaced apart along the axial direction, and each first rope passes through a first rope outlet and is wound around the corresponding first drum shaft, and the first rope outlet is located at the bottom of the gate.

[0012] Optionally, a locking mechanism is provided between the end of the rotating shaft and the corresponding end plate. The locking mechanism includes a plurality of first openings and a first limiting member. The plurality of first openings are evenly spaced along the circumference of the rotating shaft on the end plate. The first limiting member is slidably sleeved on the end of the rotating shaft that extends out of the end plate and is circumferentially locked to the rotating shaft. On the side of the first limiting member near the end plate, pins are provided at intervals along the circumference of the rotating shaft. The number of pins is the same as the number of first openings. The pins are configured to be inserted into or pulled out of the first openings one by one by sliding the first limiting member on the rotating shaft.

[0013] Optionally, the cylinder body is further provided with two second drum shafts, the second drum shafts are wound with second ropes, and the ends of the second ropes are provided with hooks; The side of the cylinder is also provided with two second rope outlets. Each hook extends through one of the second rope outlets to be attached to the steel beam. The second rope outlets are located at the top of the gate.

[0014] Optionally, the first support structure and the second support structure have the same structure.

[0015] Optionally, the second support structure includes a first connecting plate, a second connecting plate, and a fixing plate. The first connecting plate and the second connecting plate are parallel to each other and are both vertically fixed to the fixing plate. A U-shaped straight groove structure with open ends is formed between the first connecting plate and the second connecting plate. The U-shaped straight groove structure is used to fit onto the protruding plate at the end of the steel beam to realize the connection between the second support structure and one end of the steel beam. A row of connecting holes is provided on the fixing plate, and the connecting holes are used to connect to one end of the first rope. Optionally, one end of the first rope is provided with an external thread and is connected to the second support structure by a nut.

[0017] The beneficial effects of this utility model's steel beam protection device are: When hoisting or performing other operations on steel beams, the first and second support structures can be connected to both ends of the steel beam, and then the first ropes can be adjusted to be in a straight state. Multiple first ropes are laid on the same horizontal plane at the bottom of the steel beam, so that the steel beam can be placed horizontally on the support structure stably through these first ropes.

[0018] By replacing the bottom surface of the steel beam with a first rope that directly contacts the supporting structure such as the jig, flexible support is achieved between the steel beam and the supporting structure. Multiple first ropes are cleverly used to protect the bottom surface of the steel beam, which is prone to scratches and collisions. This reduces the risk of the steel beam scratching or colliding with the supporting structure due to shaking when it is lifted or lowered, improves the safety and efficiency of the steel beam hoisting process, ensures the quality and progress of the project, and also reduces damage to the jig and other supporting structures.

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0031] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0032] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless explicitly stated otherwise in the context, they should be understood as "one or more". "Several" refers to one or more "one or more".

[0033] Example 1 like Figure 1 As shown, the steel beam protection device of the first embodiment of this utility model includes a first support structure 1, a second support structure 2, and multiple first ropes 3. The first support structure 1 is used to connect to one end of the steel beam 4, and the second support structure 2 is used to connect to the other end of the steel beam 4. The two ends of each first rope 3 are respectively connected to the first support structure 1 and the second support structure 2. Each first rope 3 is configured to be laid in the same horizontal plane at the bottom of the steel beam 4 and is in a stretched state, so that the steel beam 4 is placed horizontally by the first ropes 3.

[0034] In this embodiment, when the steel beam protection device is actually used, the first support structure 1 and the second support structure 2 are first connected to the two ends of the steel beam 4 respectively, and then the first ropes 3 are adjusted to be in a stretched state, and multiple first ropes 3 are laid in the same horizontal plane at the bottom of the steel beam 4, so that the steel beam 4 can be stably and horizontally placed on the support structure through these first ropes 3.

[0035] This protective device replaces the bottom surface of the steel beam 4 with direct contact with the support structure such as the jig by using the first rope 3. This achieves flexible support between the steel beam 4 and the support structure, and cleverly uses multiple first ropes 3 to protect the bottom surface of the steel beam 4, which is prone to scratches and collisions. This reduces the risk of the steel beam 4 scratching or colliding with the support structure due to shaking when it is lifted or lowered, improves the safety and efficiency of the steel beam lifting process, and ensures the quality and progress of the project. It also reduces damage to the jig and other support structures.

[0036] Optionally, the first rope 3 extends from the part of the first support structure 1 located at the bottom of the steel beam 4 to the part of the second support structure 2 located at the bottom of the steel beam 4.

[0037] like Figure 1 As shown, the first support structure 1 and the second support structure 2 are both connected to the bottom plate of the steel beam 4, and the main bodies of the first support structure 1 and the second support structure 2 extend downward to the bottom of the steel beam 4 to connect the first rope 3, so that the first rope 3 is laid in the same horizontal plane at the bottom of the steel beam 4 and is in a stretched state.

[0038] Optionally, such as Figure 2 As shown, in use, the first ropes 3 are all arranged along the length of the steel beam 4 and are evenly spaced along the width of the steel beam 4.

[0039] In this optional embodiment, each first rope 3 is arranged strictly along the length of the steel beam 4 and sequentially spaced at uniform intervals along the width of the steel beam 4, forming a regular and orderly support plane at the bottom of the steel beam 4. This ensures a more uniform distribution of the supporting force on each part of the steel beam 4 during placement, guaranteeing the stability of the steel beam 4 during placement and reducing the risk of collision between the steel beam 4 and the supporting structure or other objects. Furthermore, the uniformly spaced first ropes 3 have a certain degree of versatility and adaptability; for steel beams 4 of different lengths or widths, the support requirements can be met by adjusting the length and number of the first ropes 3. Figure 1 and Figure 2 In the diagram, the X direction is the length direction of steel beam 4, and the Y direction is the width direction of steel beam 4.

[0040] Optionally, such as Figure 3 Figure 4 As shown, the first support structure 1 includes a gate 11, which is a U-shaped straight groove with openings at both ends. The gate 11 is used to fit onto the protruding plate 41 at the end of the steel beam 4 to achieve the connection between the first support structure 1 and one end of the steel beam 4.

[0041] In this optional embodiment, the first support structure 1 is provided with a gate 11, which is a U-shaped straight groove with openings at both ends. The internal cavity of the gate 11 is adapted to the protruding plate 41 at the end of the steel beam 4. In actual use, simply align the protruding plate 41 at the end of the steel beam 4 with the gate 11 and then smoothly insert it to achieve a stable connection between the first support structure 1 and one end of the steel beam 4.

[0042] The U-shaped straight groove gate 11 can tightly fit the protruding plate 41 at the end of the steel beam 4, forming a comprehensive wrapping and support. This connection method greatly increases the contact area, making the connection between the first support structure 1 and the steel beam 4 stable and reliable. Moreover, the operator does not need complicated operating procedures; they can simply push the protruding plate 41 into the gate 11 to complete the connection, greatly shortening the connection time. Disassembly is also very convenient, improving ease of use.

[0043] It should be noted that this connection method requires the steel beam 4 to have a protruding plate 41 at its end; that is, when the steel beam 4 is placed horizontally, its end needs to have a horizontally protruding plate, such as... Figure 1 and Figure 2 The steel beam 4 shown is a box beam, with both ends of its bottom surface protruding outward to form a protruding plate 41.

[0044] Optionally, such as Figure 5As shown, the first support structure 1 also includes a plurality of first drum shafts 12, the axes of the plurality of first drum shafts 12 are collinear, and one end of each first rope 3 is wound around a first drum shaft 12 to achieve the connection between one end of the first rope 3 and the first support structure 1.

[0045] In this optional embodiment, in addition to the body gate 11 for connecting to the end of the steel beam 4, the first support structure 1 is also provided with a plurality of first drum shafts 12. The axes of these first drum shafts 12 are collinear and arranged in an orderly manner. One end of each first rope 3 is tightly and firmly wound onto the corresponding first drum shaft 12. Through this winding method, a reliable connection between one end of the first rope 3 and the first support structure 1 is cleverly and steadily achieved.

[0046] The first rope 3 is wound around the first drum shaft 12. The friction generated by the winding provides a reliable fixing force for the rope, ensuring a tight connection between the rope and the first support structure 1, preventing it from easily loosening. This also ensures a stable connection even when the steel beam 4 is subjected to various external forces, guaranteeing the stability of the steel beam 4. By rotating the first drum shaft 12, the winding length of the first rope 3 can be easily adjusted, thereby changing the rope's length and tension. During use, the rope's length and tension can be flexibly adjusted according to the actual size of the steel beam 4, its placement position, and support requirements, achieving the best support effect for the steel beam 4.

[0047] Optionally, such as Figure 5 As shown, the first support structure 1 also includes a cylinder 131 and end plates 132 disposed at both ends of the cylinder 131; multiple first drum shafts 12 are disposed inside the cylinder 131 and share a common rotating shaft 14, with the two ends of the rotating shaft 14 respectively rotatably disposed on the two end plates 132; the side of the cylinder 131 is recessed to form a gate 11, the channel of the gate 11 is arranged along the axial direction of the cylinder 131, and both ends penetrate the end plates 132; multiple first rope outlets 133 are spaced apart along the axial direction on the side of the cylinder 131, and each first rope 3 passes through a corresponding first rope outlet 133 and is wound around the corresponding first drum shaft 12, with the first rope outlet 133 disposed at the bottom of the gate 11.

[0048] In this optional embodiment, the supporting body of the first supporting structure 1 is a cylindrical shape closed at both ends, including a cylindrical body 131 and end plates 132 respectively disposed at both ends of the cylindrical body 131. Multiple first roller shafts 12 are neatly arranged inside the cylindrical body 131, sharing a common rotating shaft 14. The two ends of this rotating shaft 14 are rotatably mounted on the two end plates 132 respectively. The side of the cylindrical body 131 is specially designed with a partial recess forming a gate 11. This gate 11 has a channel arranged axially along the cylindrical body 131, and its two ends penetrate the end plates 132, facilitating the smooth insertion of the protruding plate 41 at the end of the steel beam 4. The structural design is ingenious. Meanwhile, multiple first rope outlets 133 are evenly spaced along the axial direction on the side of the cylinder 131. Each first rope outlet 133 corresponds precisely to a first rope 3. After the first rope 3 passes through the first rope outlet 133, it is wound around the corresponding first drum shaft 12. The first rope outlet 133 is located at the bottom of the gate 11. This layout allows the first rope 3 to form a supporting plane at the bottom of the steel beam 4, and also makes the whole structure more compact and reasonable.

[0049] The structure of the cylinder 131 and end plate 132 provides stable support for the first drum shaft 12 and the rotating shaft 14, giving the entire support structure high strength and rigidity. When the steel beam 4 is subjected to external forces, it can reliably bear and transmit internal forces, ensuring the safe placement of the steel beam 4. Furthermore, the cylinder 131 and end plate 132 can provide a certain degree of protection for the internal first drum shaft 12 and rotating shaft 14, reducing the impact of external environmental factors such as dust and rainwater on them, extending the service life of these components, and thus improving the reliability and durability of the entire first support structure 1.

[0050] By integrating multiple first drum shafts 12 inside the drum body 131 and sharing a single rotating shaft 14, the space occupied by the support structure is greatly reduced. This compact design makes the first support structure 1 easier to arrange on the construction site, especially suitable for working environments with limited space, thus improving space utilization. Since multiple first drum shafts 12 share a single rotating shaft 14, when it is necessary to adjust the length and tension of the first rope 3, simply rotating the rotating shaft 14 will simultaneously drive multiple first drum shafts 12 to rotate, achieving synchronous adjustment of multiple first ropes 3, making operation more convenient and efficient.

[0051] Optionally, such as Figure 6 and Figure 7As shown, a locking mechanism is provided between the end of the rotating shaft 14 and the corresponding end plate 132. The locking mechanism is used to restrict the rotation of the rotating shaft 14. The locking mechanism includes a plurality of first openings 134 and a first limiting member 16. The plurality of first openings 134 are evenly spaced along the circumference of the rotating shaft 14 on the end plate 132. The first limiting member 16 is slidably sleeved on the end of the rotating shaft 14 that extends out of the end plate 132 and is circumferentially locked to the rotating shaft 14. A plurality of pins 161 are provided at intervals along the circumference of the rotating shaft 14 on the side of the first limiting member 16 near the end plate 132. The number of pins 161 is the same as the number of first openings 134. The pins 161 are configured to be inserted into or pulled out of the first openings 134 one by one by sliding the first limiting member 16 on the rotating shaft 14.

[0052] In this optional embodiment, after adjusting the length and tension of the first rope 3, the locking mechanism can quickly lock the rotating shaft 14 to prevent it from rotating arbitrarily due to external forces, ensuring that the tension of the first rope 3 remains stable and meeting the support requirements under different working conditions.

[0053] The locking mechanism mainly consists of multiple first openings 134 and first limiting members 16. Specifically, the multiple first openings 134 are evenly and spaced along the circumference of the rotating shaft 14 on the end plate 132, providing a precise reference for the locking operation. The first limiting member 16 is slidably fitted onto the end of the rotating shaft 14 extending out of the end plate 132, and achieves circumferential locking with the rotating shaft 14. This means that in the direction of rotation, the first limiting member 16 and the rotating shaft 14 always remain synchronized and will not rotate relative to each other. On the side of the first limiting member 16 near the end plate 132, the same number of pins 161 are arranged along the circumference of the rotating shaft 14 at intervals equal to the number of first openings 134. By sliding the first limiting member 16 on the rotating shaft 14, the pins 161 can be precisely inserted into or pulled out of the first openings 134, thereby locking or unlocking the rotating shaft 14.

[0054] The operator only needs to slide the first limiting member 16 on the rotating shaft 14 to insert or pull the pin 161 into or out of the first opening 134, thus completing the locking or unlocking action of the rotating shaft 14. The whole process is simple and direct, requiring no complicated operating steps or professional skills, greatly shortening the operation time and improving construction efficiency. Multiple first openings 134 are evenly spaced along the circumference of the rotating shaft 14, and the number of pins 161 is the same. This one-to-one precise design makes the locking position more accurate and can provide sufficient locking force, avoiding stress concentration and ensuring the accuracy and stability of locking.

[0055] Specifically, such as Figure 6As shown, the end of the shaft 14 extending from the end plate 132 can be hexagonal; the first limiting member 16 has a ring-shaped body with an internal hexagonal hole, which can slide and nest on the external hexagonal shaft section at the end of the shaft 14. Due to the limiting effect of the hexagonal structure, the first limiting member 16 is circumferentially locked to the shaft 14. In addition, when it is necessary to shorten the first rope 3, an internal hexagonal wrench can be nested at the end of the shaft 14 extending from the end plate 132. By turning the wrench, the shaft 14 and the first drum shaft 12 can be rotated, thus shrinking the first rope 3 to shorten it.

[0056] It should be noted that, in addition to the locking mechanism provided between the end of the rotating shaft 14 and the corresponding end plate 132, locking of the rotating shaft 14 and the first drum shaft 12 can also be achieved using a wedge-type fixing and locking mechanism, a brake device locking mechanism, etc. For example, using a wedge-type fixing and locking mechanism, when locking is required, a wedge is inserted into the gap between the first drum shaft 12 and the drum body 131, and locking is achieved by adjusting the position of the wedge; of course, this method requires the drum body 131 to be appropriately equipped with wedges, wedge seats, and operating structures for placing wedges. For example, using a brake device locking mechanism, including components such as brake pads, brake discs, and brake cylinders; the brake cylinder pushes the brake pads to contact the brake disc, generating friction to achieve locking; when unlocking is required, the brake cylinder releases pressure, the brake pads separate from the brake disc, and the locking state is released.

[0057] Furthermore, although the locking mechanism composed of the aforementioned multiple first openings 134 and the first limiting member 16 cannot lock the rotating shaft 14 at any angle, the fact that multiple first openings 134 are evenly spaced along the circumference of the rotating shaft 14 can significantly reduce the discontinuity of the locking angle. Moreover, the first rope 3 itself is flexible, allowing it to be in a stretched state when the rotating shaft 14 is locked. Also, given that all the first ropes 3 are in the same state during the support of the steel beam 4 and will rapidly and synchronously tighten, even a small tension force when the first rope 3 is in a stretched state will not adversely affect the support of the steel beam 4, or rather, the effect is negligible.

[0058] Optionally, the opening thickness of the gate 11 is adjustable.

[0059] In this optional embodiment, the opening thickness of the gate 11 is adjustable, and its opening thickness can be flexibly adjusted according to different steel beam 4 specifications.

[0060] Specifically, the opening thickness of the gate 11 can be adjusted via a built-in mechanical adjustment device, such as a threaded adjustment rod, a slide rail locking device, etc. Figure 3The illustration provides an example in which a movable plate 111 is provided on the bottom plate of the gate 11. The movable plate 111 extends from one end of the gate 11 to the other end. Two end plates 132 are respectively provided with notches 112 at the bottom plate of the gate 11. A sliding block 113 is slidably provided in the notch 112. The top of the sliding block 113 extends out of the notch 112 and is fixedly connected to the movable plate 111. Multiple slots 114 are provided on both sides of the notch 112. Insert plates 115 are provided in the slots 114. The insert plates 115 contact and limit the sliding block 113.

[0061] In this design, notches 112 are respectively provided on the two end plates 132 at the positions corresponding to the bottom plate of the gate 11. These notches 112 provide space for the movement of the sliding block 113 and provide a sliding track for the sliding block 113 to slide smoothly. The top of the sliding block 113 extends out of the notch 112 and is firmly fixedly connected to the movable plate 111. When the sliding block 113 slides in the notch 112, it will drive the movable plate 111 to move together, thereby realizing the adjustment of the height position of the movable plate 111, and thus adjusting the opening thickness of the gate 11. In order to achieve precise positioning of the sliding block 113, multiple slots 114 are provided on both sides of the notch 112. These slots 114 are evenly distributed in the vertical direction. When the sliding block 113 moves to the appropriate position, the insert plate 115 is inserted into the corresponding slot 114. The insert plate 115 will contact and abut against the sliding block 113, playing a limiting role and ensuring that the position of the movable plate 111 remains stable.

[0062] Optionally, such as Figure 5 As shown, two second drum shafts 15 are also provided inside the cylinder 131. The second drum shafts 15 are wound with second ropes 151, and the ends of the second ropes 151 are provided with hooks 152. The side of the cylinder 131 is also provided with two second rope outlets 137. Each hook 152 extends through a corresponding second rope outlet 137 to be hooked onto the steel beam 4. The second rope outlets 137 are located at the top of the gate 11.

[0063] In this optional embodiment, two second drum shafts 15 are cleverly arranged inside the cylinder 131, providing reliable winding support for the second rope 151. A hook 152 is provided at the end of the second rope 151. The design of the hook 152 increases the reliability of the connection between the first support structure 1 and the steel beam 4, and also makes the connection operation between the second rope 151 and the steel beam 4 simple and quick. To allow the second rope 151 to smoothly extend out of the cylinder 131 and hook onto the steel beam 4, multiple second rope outlets 137 are also provided on the side of the cylinder 131.

[0064] In addition, such as Figure 5As shown, the two second drum shafts 15 are independent of each other, allowing the second rope 151 and hook 152 to extend to different lengths to meet the hanging requirements at different positions on the steel beam 4. Specifically, the hook 152 can be hung on openings, flanges, or other structures on the steel beam 4. In addition, one end of the shaft of each second drum shaft 15 is rotatably mounted on an end plate 132, and a locking mechanism is also provided between the end plate 132 and the corresponding shaft to restrict the rotation of the second drum shaft 15.

[0065] Optionally, such as Figure 4 As shown, the first rope outlet 133, the second rope outlet 137, and the gate 11 are located on the same side of the cylinder 131; the first rope outlet 133 is located at the top of the gate 11, and the second rope outlet 137 is located at the top of the gate 11, so that the first rope 3 and the second rope 151 can extend at a suitable angle, avoiding additional tension or stress concentration caused by improper rope outlet angle, and further enhancing the stability of the support.

[0066] In addition, the first rope 3 can be a steel wire rope made of multiple strands of steel wire, which has high strength and good flexibility. When the steel beam 4 is placed horizontally on the supporting structure by the first rope 3, the first rope 3 and the bottom plate of the steel beam 4 maintain a certain distance. This distance is set according to the actual situation, specifically determined by the height difference between the first rope outlet 133 and the gate 11.

[0067] Optionally, such as Figure 5 As shown, the end plate 132 is cleverly designed to improve the versatility and combination flexibility of the first support structure 1. One end plate 132 of each first support structure 1 has a groove 135 at its center, while the other end plate 132 has a corresponding convex shaft 136 at its center. The size and shape of the convex shaft 136 perfectly match the groove 135, allowing for a tight fit.

[0068] In actual construction scenarios, when facing a steel beam 4 with a large width, a single support structure may not be sufficient to meet the support requirements. In this case, multiple first support structures 1 and multiple second support structures 2 can be combined. At one end of the steel beam 4, two adjacent first support structures 1 can be connected in series by inserting a convex shaft 136 into a groove 135. This connection method is simple and efficient; construction workers only need to align the convex shaft 136 of one first support structure 1 with the groove 135 of another first support structure 1 and gently insert it to complete the connection, without the need for complicated tools or operating procedures.

[0069] In addition, such as Figure 1 and Figure 2 As shown, the first support structure 1 and the second support structure 2 have the same structure and are arranged symmetrically. Specifically, the second support structure 2 has the same structure as the first support structure 1 and is connected to both ends of the steel beam 4 in use.

[0070] Example 2 like Figure 8 and Figure 9 As shown, the steel beam protection device of the second embodiment of this utility model includes a first support structure 1, a second support structure 2, and multiple first ropes 3. The first support structure 1 is used to connect to one end of the steel beam 4, and the second support structure 2 is used to connect to the other end of the steel beam 4. The two ends of each first rope 3 are connected to the first support structure 1 and the second support structure 2, respectively. In use, the first support structure 1 and the second support structure 2 are respectively connected to the two ends of the steel beam 4, and the first ropes 3 are all straight and laid in the same horizontal plane at the bottom of the steel beam 4, so that the steel beam 4 is placed horizontally on the support structure by the first ropes 3.

[0071] Optionally, the second support structure 2 includes a first connecting plate 21, a second connecting plate 22, and a fixing plate 23. The first connecting plate 21 and the second connecting plate 22 are parallel to each other and are both vertically fixed to the fixing plate 23. A U-shaped straight groove structure with open ends is formed between the first connecting plate 21 and the second connecting plate 22. The U-shaped straight groove structure is used to fit onto the protruding plate 41 at the end of the steel beam 4 to realize the connection between the second support structure 2 and one end of the steel beam 4. A row of connecting holes 24 are opened on the fixing plate 23. The connecting holes 24 are used to connect to one end of the first rope 3.

[0072] In this optional embodiment, the second support structure 2 includes a first connecting plate 21, a second connecting plate 22, and a fixing plate 23. The first connecting plate 21 and the second connecting plate 22 are arranged parallel to each other, and both are fixed to the fixing plate 23 by vertical welding. Ribs can be provided at the vertical connection corners to ensure a stable connection. A U-shaped straight groove structure with open ends is formed between the first connecting plate 21 and the second connecting plate 22. The size of the U-shaped straight groove structure is adapted to the size of the protruding plate 41 at the end of the steel beam 4, similar to the gate 11 structure in the first embodiment. Through nesting, a precise and stable connection between the second support structure 2 and one end of the steel beam 4 can be achieved.

[0073] A row of connecting holes 24 are provided on the fixing plate 23. The connecting holes 24 are circular through holes. The connecting holes 24 are used to connect with one end of the first rope 3 through a preset connection method, such as rope clamping, braiding and knotting, or using special connectors.

[0074] Furthermore, the first support structure 1 and the second support structure 2 have the same structure and are arranged symmetrically. Specifically, the second support structure 2 has the same structure as the first support structure 1 and is connected to both ends of the steel beam 4 during use. The difference between the second embodiment and the first embodiment lies in the different structures of the first support structure 1 and the second support structure 2.

[0075] Optionally, one end of the first rope 3 is provided with an external thread and is connected to the second support structure 2 by a nut.

[0076] In this optional embodiment, the external thread at one end of the first rope 3 engages with the nut to form a high-strength threaded connection, effectively preventing loosening or detachment between the first rope 3 and the second support structure 2. The connection is completed simply by tightening the nut, making operation simple and convenient, and disassembly easy. Furthermore, the tension and straightening of the first rope 3 can be achieved by adjusting the screw depth of the nut. However, the length adjustable by the nut is limited; therefore, the length of the first rope 3 needs to be predetermined and selected to match the steel beam 4.

[0077] Example 3 like Figure 10 As shown, the steel beam protection device of the third embodiment of this utility model includes a first support structure 1, a second support structure 2, and multiple first ropes 3. The first support structure 1 is used to connect to one end of the steel beam 4, and the second support structure 2 is used to connect to the other end of the steel beam 4. The two ends of each first rope 3 are connected to the first support structure 1 and the second support structure 2, respectively. In use, the first support structure 1 and the second support structure 2 are respectively connected to the two ends of the steel beam 4, and the first ropes 3 are all straight and laid in the same horizontal plane at the bottom of the steel beam 4, so that the steel beam 4 is placed horizontally on the support structure by the first ropes 3.

[0078] The first support structure 1 adopts the structural form of the first embodiment, and the second support structure 2 adopts the structural form of the second embodiment. In this way, after the shaft 14 of the first support structure 1 is locked, the length of the first rope 3 can be finely adjusted to be tensioned and straightened by the nut of the second support structure 2.

[0079] Example 4 like Figure 11 As shown, the steel beam storage structure of this utility model includes the above-mentioned steel beam protection device, and also includes a plurality of spaced-apart crossbeams 5, which are laid flat on the ground. The steel beam 4 is placed on the plurality of crossbeams 5 by a plurality of first ropes 3.

[0080] Optionally, the crossbeam 5 has a rectangular cross-section and a horizontal top support surface, which indirectly supports the steel beam 4 through the first rope 3.

[0081] The steel beam storage structure allows the first rope 3 to replace the bottom surface of the steel beam 4 in direct contact with the support structure such as the jig, realizing flexible support between the steel beam 4 and the support structure. This reduces the risk of the steel beam 4 scraping or colliding with the support structure due to shaking when it is lifted or lowered, improves the safety and efficiency of the steel beam hoisting process, and ensures the quality and progress of the project. It also reduces damage to the jig and other support structures.

[0082] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
