Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction technology, specifically relating to a steel structure device for high-altitude transportation of roof panels. Background Technology

[0002] With the demands of modern industrial development and the improvement of steel structure construction technology, color steel sheet roofing is commonly used in the design of large industrial plant buildings and public long-span roofs to reduce the roof's self-weight and load. To achieve better waterproofing, the color steel sheets are generally pressed continuously along their length. However, the horizontal transportation of continuous, high-altitude color steel sheets has always presented numerous challenges, directly impacting the project's progress, quality, cost, and safety.

[0003] Currently, the following methods are commonly used for on-site high-altitude transportation of color steel roof panels:

[0004] (1) In-workshop forming and on-site hoisting method: The forming of the color steel plates is completed in the workshop in advance, and then the formed color steel plates are transported to the construction site and hoisted onto the roof using a truck crane. This method is suitable for the construction of small factory roofs. For large factory buildings, especially those with long single-slope roofs, this method has obvious limitations. Due to the long single-slope roof, water leakage is prone to occur at the overlapping parts of the color steel plates. In addition, if the color steel plates are too long, there will be many difficulties in transportation, making it difficult to meet construction requirements.

[0005] (2) On-site ground pressing and ramp transport method: The color steel plates are pressed on the construction site, and then manually transported to the roof along a specially constructed ramp. Because this method requires the construction of a relatively long ramp according to the roof slope, the construction preparation work is more complicated, and a lot of manpower and resources are required in the process of ramp construction and color steel plate transport. Therefore, this method is suitable for the roof construction of small and medium-sized factories, especially projects with short single-slope roofs.

[0006] (3) On-site ground pressing and steel wire slide hoisting method: The color steel plate is pressed on the construction site, and then hoisted from the gable wall to the roof by manual operation using steel wire and slide devices. The specific operation steps are as follows: First, along the gable wall direction, stainless steel coated steel wire is set at intervals of one meter, one end is fixed to the steel beam on the gable wall, and the other end is fixed to the ground with steel bars; before transporting the color steel plate, ropes are used to fix the color steel profiled plate, and anti-wear pads should be added at the contact point between the plate and the rope to prevent the plate from being scratched; according to the length of the color steel plate, the personnel pulling the plate are reasonably arranged, and the person in charge on the ground gives unified command, and the personnel pulling the plate exert unified force to ensure that the color steel profiled plate is smoothly pulled to the roof. Although this method can complete the vertical transportation of color steel profiled plates, it increases the labor intensity of workers, the work efficiency is very low, and the color steel plate may be scratched during transportation, affecting its appearance and quality.

[0028] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, a feature defined with "first," "second," or "third" may explicitly or implicitly include at least one of that feature.

[0030] like Figure 1As shown, this utility model provides a steel structure device for high-altitude transportation of roof panels, which includes multiple steel structure units. Each steel structure unit includes connectors 1, flange plates 2, chord assemblies 3, horizontal web member assemblies 4, and diagonal web member assemblies 5. Two flange plates 2 are provided, each flange plate 2 being triangular, preferably an equilateral triangle with strong stability. Each side of each flange plate 2 is provided with several connectors 1 for fixing the two steel structure units together. The spacing between the connectors 1 on each side of the flange plate 2 is consistent, ensuring that the flange plates 2 are evenly stressed during connection, preventing local stress concentration, thereby improving the reliability and safety of the connection, and avoiding structural deformation or damage caused by uneven stress. In this embodiment, each side of the flange plate 2 is provided with 5 connectors 1 of the same size and with consistent spacing. In other embodiments, the number of connectors 1 used can be determined according to the actual construction conditions and the size of the flange plate 2.

[0031] In this embodiment, the connecting component 1 is a through bolt. The construction process of through bolt connection is relatively simple and easy to install, which can better ensure the progress and quality of the project. This connection method has reliable force transmission and the advantages of convenient installation and disassembly. In addition, through bolts have the advantages of small connection deformation and can be reused multiple times. While improving the installation quality and efficiency of fixed connection between steel structure units, it also has a certain degree of economic practicality.

[0032] like Figure 2 As shown, connector 1 includes a screw 1-1, two washers 1-2, and two nuts 1-3. The screw 1-1 of connector 1 is inserted into the through hole of flange plate 2. The two washers 1-2 and two nuts 1-3 are located on both sides of flange plate 2, with washers 1-2 positioned between nuts 1-3 and flange plate 2. Washers 1-2, located below nuts 1-3, act as a buffer, allowing the preload to be evenly distributed across flange plate 2, reducing local stress concentration, lowering the risk of deformation and damage to parts, and improving connection stability. During construction, the screw 1-1 of connector 1 passes through the two adjacent flange plates 2 of two steel structural units, and nuts 1-3 are tightened to secure the two steel structural units. The diameter of the through hole on flange plate 2 is slightly larger than the diameter of the screw 1-1 of connector 1, ensuring that the screw 1-1 can be smoothly inserted into the through hole. In actual construction, the number of connected steel structural units can be flexibly adjusted according to the specific construction scenario to accommodate the transportation of roof panels 6-3 of different lengths.

[0033] In the device provided by this utility model, such as Figure 3As shown, the chord assembly 3 includes three chords: a first chord 3-1, a second chord 3-2, and a third chord 3-3. The chords can be made of round or square steel pipes; in this embodiment, round steel pipes are used. The first chord 3-1, the second chord 3-2, and the third chord 3-3 are all of equal thickness and length. The two ends of the first chord 3-1, the second chord 3-2, and the third chord 3-3 are perpendicularly welded and fixed to the three vertices of the two flange plates 2, respectively. The first chord 3-1, the second chord 3-2, and the third chord 3-3 are parallel to each other. Figure 4 As shown, a steel wire rope 6-1 is installed on the first chord 3-1, connecting it to the lifting mechanism above. A lifting structure 6-2 for hoisting the roof panel 6-3 is installed on the plane formed by the second chord 3-2 and the third chord 3-3. The distance between adjacent lifting structures 6-2 and the number of lifting structures 6-2 can be adjusted according to actual construction needs. In this embodiment, the lifting structure 6-2 can be made of hemp rope. The roof panel 6-3 to be transported is bound to the second chord 3-2 and the third chord 3-3 on the bottom surface of the device using the lifting structure 6-2. A certain distance is maintained between the roof panel 6-3 to be transported and the second chord 3-2 and the third chord 3-3 to facilitate the detachment of the lifting structure 6-2 after the roof panel 6-3 is placed. Several lifting points are set on the first chord 3-1; in this embodiment, three lifting points are set. One end of the steel wire rope 6-1 passes through these lifting points and is bound and fixed to the first chord 3-1.

[0034] In the device provided by this utility model, several sets of transverse web member assemblies 4 are arranged at intervals along the length direction of the chord member assembly 3. Each set of transverse web member assemblies 4 includes a first transverse web member 4-1, a second transverse web member 4-2, and a third transverse web member 4-3. The first transverse web member 4-1 connects the first chord member 3-1 and the second chord member 3-2; the second transverse web member 4-2 connects the first chord member 3-1 and the third chord member 3-3; and the third transverse web member 4-3 connects the second chord member 3-2 and the third chord member 3-3. The two ends of each transverse web member are fixedly connected to the two adjacent chord members by welding. The three transverse web members of each set of transverse web member assemblies 4 form an equilateral triangle, making the steel structure unit more stable. The transverse web members can be made of round steel pipes or square steel pipes. In this embodiment, round steel pipes are used for the transverse web members. A single steel structure unit contains five sets of transverse web member assemblies 4, which are spaced apart and have the same specifications. The distance between any two adjacent sets of transverse web member assemblies 4 and the distance between the nearest transverse web member assembly 4 and the flange plate 2 are both equal. To improve the lateral stiffness of the steel structure unit and ensure its lateral stability, diagonal web member assemblies 5 are provided between adjacent transverse web member assemblies 4 for stability. Each diagonal web member assembly 5 includes several diagonal web members, each diagonally fixed within the quadrilateral formed by the chord and transverse web members. In this embodiment, the diagonal web member assembly 5 includes two diagonal web members: a first diagonal web member 5-1 and a second diagonal web member 5-2. The first diagonal web member 5-1 connects the first chord 3-1 and the second chord 3-2, and the diagonal web member 5-2 connects the first chord 3-1 and the third chord 3-3. In other embodiments, an additional diagonal web member can be added between the second chord 3-2 and the third chord 3-3 to increase structural stability. One steel structure unit contains six sets of diagonal web member assemblies 5. The diagonal web members can be made of round or square steel pipes. In this embodiment, round steel pipes are used, and both ends of each diagonal web member are fixedly connected to the adjacent horizontal web member assembly 4 by welding. In this embodiment, all welding methods adopt full penetration welding, which can achieve very high welding strength and is suitable for occasions requiring high-strength connections. The characteristics of full penetration welds are relatively large penetration depth, relatively wide heat-affected zone, and high welding strength. The use of full penetration welding makes the connection between chord members, horizontal web members, and diagonal web members more robust, improving construction safety.

[0035] like Figure 5 As shown, the device provided by this utility model can be manufactured modularly. The total length L of the device is 6 times the length X1. The lengths of X1, X2, X3, X4, X5, and X6 are all equal, as are the lengths of Y1, Y2, and Y3. Equal distances between the parts help achieve uniform stress distribution on the steel structure, avoiding localized stress concentration, thereby improving the overall stability and load-bearing capacity of the structure. The actual lengths marked can be adjusted according to the actual site conditions. Modules are connected to each other via flange plates 2 and connectors 1, forming new modules. The structure is simple and can be assembled on-site.

[0036] In the device provided by this utility model, after assembling a steel structure adapted to the length of the roof panel 6-3 to be transported, the roof panel 6-3 is tied together using a hoisting structure 6-2. The roof panel 6-3, along with the device provided in this embodiment, is then transported to a designated location using the main boom of a crane. After the roof panel 6-3 is transported to the designated location, it is unloaded, and the fixing device provided in this embodiment is lifted back by the crane for subsequent transport of the roof panel 6-3, achieving repeated use and reducing production costs.

[0037] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
