Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, especially the field of steel structure installation technology, specifically a sliding frame device for assembling a large-span steel structure arched roof. Background Technology
[0002] With advancements in construction technology, large-span steel structures are increasingly being used in large public buildings such as stadiums, exhibition halls, and airport terminals. These buildings typically require covering large areas of column-free space, thus placing higher demands on the span and load-bearing capacity of the steel structures.
[0003] An arched roof is an architectural structural form characterized by its arched shape, typically used in large-span buildings. The design of arched roofs is inspired by arched structures in nature, such as the arches of bridges. This shape effectively distributes loads, improving structural stability and load-bearing capacity. Due to its excellent mechanical properties and aesthetically pleasing appearance, arched roofs have become a common choice for large-span buildings. The arched structure effectively distributes loads, reducing material usage while providing more interior space.
[0004] However, the construction of large-span arched roofs often faces numerous challenges, such as the difficulty of working at heights, the large weight of components, and the high precision requirements for installation. Traditional construction methods, such as hoisting and segmented assembly, usually require the use of many fixed assembly frames, which often result in low construction efficiency, high costs, and numerous safety hazards.
[0005] To address the aforementioned technical issues, Chinese utility model patent CN203430063U discloses a sliding assembly frame for installing the main truss of a large-span steel structure roof. This frame includes sleepers, tracks, wheels, wheel frames, a steel base frame, a steel pipe frame, and a steel pipe connecting frame. The sleepers are evenly spaced in three rows. A set of three tracks is laid on each row of sleepers, for a total of three sets, or nine tracks. A steel base frame is erected on the three sets of tracks. Nine sets of wheels are installed at the bottom of this steel base frame. Steel pipe sleeves are evenly welded in a rectangular arrangement on the upper surface of each steel frame of the steel base frame. Steel pipes of equal height are inserted into each steel pipe sleeve. Horizontal, longitudinal, or diagonal bracing pipes are evenly installed from bottom to top on each steel pipe on the same side of each steel frame, forming a vertical steel pipe frame. The upper parts of each steel pipe frame are connected together by steel pipe connecting frames. The aforementioned utility model device has a simple structure, with the formwork under each main truss forming a unified whole, exhibiting good integrity. The use of sleepers under the foundation track ensures even stress distribution. However, during continuous construction, the formwork body can only be installed after the concrete of the lower floors has reached a certain strength, resulting in a relatively long technical interval and hindering the shortening of the construction period. Secondly, the formwork body is entirely constructed of connected steel pipes, which limits its self-strength and its ability to withstand vertical loads is generally limited. Furthermore, the entire construction process relies on a single steel structure formwork; it can only slide to the next main truss after the current one is installed, leading to low installation efficiency. Additionally, the previous main truss may experience localized settlement and displacement after unloading, negatively impacting the overall accuracy of the roof steel structure system. Finally, the lack of a retractable adjustment device at the top increases labor costs, and manual climbing for work poses safety hazards. Therefore, the application of the aforementioned sliding assembly formwork for installing large-span steel roof main trusses in the field of building construction technology is not feasible.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0030] Example: Figures 1 to 7 As shown, a sliding frame device for assembling a large-span steel arched roof is mainly used to install the main body 3 of the assembly frame. The main body 3 of the assembly frame is assembled from multiple tower crane standard sections 3-1. The specific number of tower crane standard sections 3-1 can be set as needed, mainly to improve installation efficiency by installing multiple tower crane standard sections 3-1 at once. The sliding frame device in this embodiment mainly consists of a frame sliding track assembly 1, a frame sliding support assembly 2, a frame top adjustable assembly 4, a traction mechanism 5, and a fixing mechanism 6. The frame sliding support assembly 2 is installed on the frame sliding track assembly 1 and can slide on the frame sliding track assembly 1. The main body 3 of the assembly frame is used to install on the frame sliding support assembly 2. The frame top adjustable assembly 4 is installed above the main body 3 of the assembly frame. The traction mechanism 5 is installed at the end of the frame sliding track assembly 1 to connect to the main body 3 of the assembly frame and to adjust and fix the position of the main body 3 of the assembly frame.
[0031] like Figure 2As shown, the aforementioned jig sliding track assembly 1 has a supporting slide rail 1-1, allowing the jig sliding support assembly 2 to slide along the supporting slide rail 1-1, thereby moving the assembled jig body 3 placed on the jig sliding support assembly 2 to the desired position. To facilitate the installation of the supporting slide rail 1-1, the jig sliding track assembly 1 in this embodiment also has a supporting beam 1-2 and a supporting column 1-3. The bottom of the supporting slide rail 1-1 is mounted on the box-shaped supporting beam 1-2, and the bottom of the supporting beam 1-2 is mounted on the supporting column 1-3. The lower end of the supporting column 1-3 is fixed to the main beam of the floor below to ensure structural stability, thereby ensuring the stability of the jig sliding support assembly 2 and the assembled jig body 3 located above it. The supporting slide rail 1-1 is an I-beam structure, installed along the centerline of the supporting beam 1-2. To further ensure the structural strength of the connection between the support rail 1-1 and the support beam 1-2 and prevent them from separating, the support rail 1-1 can be fixed to the support beam 1-2 by welding. To enable movement on the support rail 1-1, the jig sliding support assembly 2 in this embodiment includes a support pulley 2-1, a pulley bracket 2-2, and a lifter 2-3. The support pulley 2-1 is mounted on the pulley bracket 2-2 and can slide along the length of the support rail 1-1. The lifter 2-3 is mounted on top of the pulley bracket 2-2. To ensure the stability of the jig body 3 during movement, i.e., to ensure the balance of the jig body 3, multiple support pulleys 2-1 can be provided. These multiple support pulleys 2-1 are respectively mounted on the pulley bracket 2-2 via rotating shafts 2-4. In this embodiment, there are two support pulleys 2-1, spaced apart. The pulley bracket 2-2 has a mounting plate 2-5 on top for mounting the lifting device 2-3. To facilitate the installation of the lifting device 2-3 and ensure its stability during installation and use, the width of the mounting plate 2-5 is greater than the width of the top of the pulley bracket 2-2. The lifting device 2-3 is mounted vertically on the mounting plate 2-5, and a support plate 2-6 is also mounted on top of the lifting device 2-3. The support plate 2-6 is connected to the assembly frame body 3 via a connector 3-5. The lifting device 2-3 can be a jack, which can push the assembly frame body 3, placed on the support plate 2-6, to the desired installation position. The connector 3-5 can be a simple, economical, and practical locking bolt, facilitating the assembly and disassembly of the assembly frame body 3 and reducing the difficulty of assembly and disassembly.To facilitate the manufacturing of the sliding frame device and reduce both manufacturing and usage costs, the pulley bracket 2-2 in this embodiment consists of two opposing support plates 2-2-1. A structural reinforcing plate 2-7 is installed between the outer side of the support plate 2-2-1 and the bottom of the mounting plate 2-5. There are multiple structural reinforcing plates 2-7, and adjacent structural reinforcing plates 2-7 are equidistantly arranged.
[0032] The aforementioned assembly frame body 3 mainly consists of a tower crane standard section 3-1 and a conversion platform 3-2. The tower crane standard section 3-1 is detachably connected to the conversion platform 3-2 via a connecting bolt 3-6. The bottom of the assembly frame body 3, i.e., the conversion platform 3-2, is connected to the support plate 2-6 in the frame sliding support assembly 2 via connecting bolts. After the assembly frame body 3 is installed, the frame sliding support assembly 2 can be removed for reuse. A lifting ring 3-4 is fixed to the conversion platform 3-2 facing the traction mechanism 5. The traction mechanism 5 includes a winch 5-1 and a traction mechanism platform 5-2. The winch 5-1 is installed on the traction mechanism platform 5-2 and connected to the assembly frame body 3 via a wire rope 5-3. That is, the connection between the traction mechanism 5 and the assembly frame body 3 is achieved by fixing one end of the wire rope 5-3 to the lifting ring 3-4, ensuring the stability of the assembly frame body 3 during movement. The support pulley 2-1 in the aforementioned jig sliding support assembly 2 can slide forward under the action of the aforementioned winch 5-1.
[0033] In this embodiment, the adjustable component 4 at the top of the frame mainly consists of a bracket 4-1, a rack 4-2, a drive motor 4-3, a transmission rail 4-4, and a transmission gear 4-5. The bracket 4-1 is arranged in a "well" shape. The drive motor 4-3 is mounted on the bracket 4-1. The transmission gear 4-5 is mounted on the output end of the drive motor 4-3 via a transmission shaft. The rack 4-2 meshes with the transmission gear 4-5 to drive the transmission gear 4-5 through the drive motor 4-3, thereby raising and lowering the rack 4-2 within the transmission rail 4-4. The transmission rail 4-4 is a square steel tube structure, and two elongated protrusions 4-4-1 are formed on the inner wall of the transmission rail 4-4. The rack 4-2 has a recess 4-2-1 on its side that matches the elongated protrusions 4-4-1. The elongated protrusions 4-4-1 are embedded in the recesses 4-2-1, ensuring that the rack 4-2 does not wobble during movement. Lubricating oil is applied between the transmission rail 4-41 and the rack 4-2 to reduce wear. The top surface of the transmission rail 4-4 is approximately 50cm higher than the bracket 4-1, and the bottom surface of the transmission rail 4-4 is approximately 2m lower than the bracket 4-1, so the adjustable elevation range is 2 meters. The length of the transmission rail 4-4 can be adjusted according to the actual situation. A steel support 4-6 is also provided at the end of the rack 4-2.
[0034] In this embodiment, the fixing mechanism 6 mainly consists of a frame connecting beam 6-1 and a guy rope. The frame connecting beam 6-1 is used to connect two adjacent tower crane standard sections 3-1 and fix the distance between the two adjacent tower crane standard sections 3-1. One end of the guy rope is fixed to the bracket 4-1, and the other end of the guy rope is fixed to the frame sliding track assembly 1 or the steel column at the edge of the floor.
[0035] In this embodiment, the sliding frame device for assembling the large-span steel arched roof includes the following steps during steel structure installation:
[0036] S1. Weld the support column 1-3 to the main steel structure beam of the lower floor. The spacing depends on the column spacing of the lower floor. The position of the support column 1-3 should be consistent with the direction of the support rail 1-1. The elevation of the support column 1-3 should be kept as horizontal as possible to ensure that the support rail 1-1 placed on it is horizontal.
[0037] S2. Fix the support beam 1-2 above the support column 1-3. The length of the support beam 1-2 is the length covered by the main truss of the steel structure roof to be installed.
[0038] S3. Install support rail 1-1 along the top center line of the above-mentioned support beam 1-2. The length of support rail 1-1 is the length covered by the main truss of the steel structure roof to be installed.
[0039] S4. The traction mechanism platform 5-2 is rigidly connected to the end of the steel structure roof of the support beam 1-2 in the installation direction. A winch 5-1 is installed above the traction mechanism platform 5-2, and a steel wire rope 5-3 is wound on the drum of the winch 5-1.
[0040] S5. Assemble the sliding support assembly 2, the main body 3, and the adjustable top assembly 4 of the frame on the ground. After the frame is assembled, use a lifting device to hoist it onto the support rail 1-1. The sliding support assembly 2 of the frame needs to be temporarily fixed to the support beam 1-2.
[0041] S6. Following the operation of S5, install 3 jigs on the same support slide rail 1-1. The jigs are connected by jig connecting beam 6-1, and the 3 jigs are connected into a whole. In S4, the steel wire rope 5-3 is connected to the lifting ring 3-4 on the side of the conversion platform 3-2 in the first jig.
[0042] S7. The winch 5-1 on the traction mechanism 5 starts and pulls the jig to the bottom of the main steel truss through the wire rope 5-3. In the direction from one end of the track to one end of the traction mechanism 5, the first jig, the second jig, and the third jig are numbered jig ①, jig ②, and jig ③, respectively. Jig ①, jig ②, and jig ③ correspond to the 3rd main truss, the 2nd main truss, and the 1st main truss.
[0043] S8. Activate the lifting device 2-3, i.e., the hydraulic jack, in the tire frame sliding support assembly 2 to make the surface of the entire tire frame conversion platform 3-2 on the same horizontal plane.
[0044] S9. After the verticality of the frame is adjusted, the drive motor 4-3 in the adjustable component 4 at the top of the frame drives the transmission gear 4-5 to adjust the rack 4-2 to move up and down. Then, the total station is used to mark the position of the fulcrum. The two work together to make the steel support 4-6 reach the designated position. Then, the guy rope in the fixing mechanism 6 is pulled.
[0045] S10. After the entire device is in place, the first, second and third main trusses of the steel structure can be hoisted. After hoisting, the jig ③ is moved to support the completed third main truss. The jig ② and jig ① are moved to support the fourth and fifth main trusses at the same time, and the above-mentioned positioning operation is completed.
[0046] S11. Repeat step S10 to complete the assembly of all roof steel structures;
[0047] S12. After the steel structure roof structure is installed, the sliding frame device in this embodiment can be removed.
