Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of industrial buildings, and particularly to a corridor structure with rolling supports and an installation method thereof. Background Art
[0002] In recent years, with the rapid development of China's industry, it is difficult to ensure the continuity of large-scale production by using motor vehicles to transport materials in factories, and the transportation cost is high. Continuous transportation belts, pipe belts, etc. can not only ensure the sufficient supply of materials, but also have low costs and can achieve automatic control. This has promoted the wide application of steel structure corridors carrying mechanized equipment such as conveyor belts and pipe belts in enterprises such as metallurgy, mines, coal, power generation, cement, and ports. However, the traditional steel structure corridor has a reinforced concrete support supporting a brick-concrete structure corridor body, and this structure form has a series of obvious disadvantages.
[0003] First of all, its large self-weight is a prominent problem. The reinforced concrete support and the brick-concrete structure corridor body have a relatively large density of the materials themselves, resulting in a relatively large weight of the entire corridor structure. This not only increases the difficulty and cost of infrastructure construction, but also has an adverse impact on the seismic performance of the building.
[0004] Secondly, the small span limits the application range of the corridor. Due to the limitations of the structural strength and stability of the traditional corridor, its span is generally small. In some occasions where a large space needs to be spanned, the traditional corridor may not meet the requirements, or more support structures need to be set up, increasing the construction cost and floor area.
[0005] Moreover, the traditional corridor occupies a large area. Due to the limitations of its structural form, a large foundation support area and surrounding space are required, which is undoubtedly a problem that cannot be ignored when land resources are becoming increasingly tense. At the same time, the industrialization level of the traditional corridor is low, most of the construction work needs to be carried out on-site, the construction process is complex, the labor intensity is large, and the construction quality is difficult to guarantee.
[0006] In addition, poor seismic performance is also a major drawback of the traditional corridor. In earthquake-prone areas, the corridors of this structural form are difficult to withstand earthquake effects, are prone to damage, and affect production safety and the safety of people's lives and property. Moreover, its construction period is relatively long. From foundation construction to corridor body construction, and then to equipment installation and commissioning, it often takes a long time, which is an unfavorable factor for enterprises to quickly put into production and improve production efficiency. Summary of the Invention
[0007] In order to overcome a series of problems existing in the traditional steel structure corridor, such as large self-weight, small span, large land occupation, low industrialization level, poor seismic performance, and long construction period, the present invention provides a corridor structure with rolling supports and an installation method thereof.

[0018] As a preferred embodiment of the present invention, the corridor steel support includes a first corridor steel support and a second corridor steel support arranged oppositely. The top of the first corridor steel support is flexibly connected to the bottom of one side of the steel truss corridor structure through the rolling support, and the top of the second corridor steel support is rigidly connected to the bottom of the other side of the steel truss corridor structure.
[0019] As a preferred embodiment of the present invention, two first mounting seats arranged oppositely left and right are provided at the top of the first corridor steel support, and the two first mounting seats are respectively flexibly connected to the left and right ends of the bottom of one side of the steel truss corridor structure through the rolling supports;
[0020] Two second mounting seats arranged oppositely left and right are provided at the top of the second corridor steel support, and the two second mounting seats are respectively rigidly connected to the left and right ends of the bottom of the other side of the steel truss corridor structure.
[0021] In a second aspect, the present invention provides an installation method for a corridor structure with a rolling support as described in any of the above embodiments, including:
[0022] Step S1, construction preparation, specifically: measuring and setting out lines, completing the installation of the embedded parts of the corridor steel support, and pouring the ground concrete foundation;
[0023] Step S2, installing the corridor steel support, specifically: after the corridor steel support is fabricated in the factory, it is transported to the construction site as a whole, and the corridor steel support is installed;
[0024] Step S3, assembling the side steel truss, specifically: after the side steel truss is fabricated in the factory, it is transported to the construction site as a whole, and assembled one by one;
[0025] Step S4, assembling the lower steel beam support frame, specifically: after each component of the lower steel beam support frame is fabricated in the factory, it is transported to the construction site and assembled with the side steel truss;
[0026] Step S5, assembling the upper steel beam support frame, specifically: after each component of the upper steel beam support frame is fabricated in the factory, it is transported to the construction site and assembled with the side steel truss to form the steel truss corridor structure;
[0027] Step S6: Install the rolling support, specifically: After the rolling support is fabricated in the factory, it is transported to the construction site as a whole, and the rolling support is installed at the bottom of one side of the steel truss corridor structure.
[0028] Step S7: Hoist the steel truss corridor structure, specifically: Hoist the steel truss corridor structure with the installed rolling support as a whole to the top of the corridor steel support.
[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0030] 1. By providing a flexible connection between the rolling support and the corridor steel support on one side of the steel truss corridor structure, the horizontal displacement release of the corridor steel support and the steel truss corridor structure can be realized, enabling the corridor structure to better adapt to horizontal forces, avoiding structural damage caused by limited horizontal displacement, greatly improving the ability of the corridor structure to withstand horizontal loads and seismic resistance, and ensuring production safety and the safety of personnel's lives and property in earthquake-prone areas;
[0031] 2. The adoption of the corridor steel support and the steel truss corridor structure to replace the traditional reinforced concrete support and the corridor body of the brick-concrete structure not only occupies a small area but also significantly reduces the weight of the entire corridor structure, thereby reducing the difficulty and cost of foundation construction;
[0032] 3. It breaks through the limitations of the traditional structure in terms of span. The span of the corridor structure can generally reach about 30m, and when the belt climbing height increases, the span can even exceed 50m; The larger span reduces the setting of the support structure, not only reducing the construction cost but also the occupied area, and at the same time providing greater flexibility for the layout of the corridor;
[0033] 4. The corridor structure is installed by means of factory fabrication and on-site assembly, with a high degree of industrialization. Compared with the traditional method where most construction work is carried out on-site, it reduces the complex on-site construction processes, reduces the labor intensity, and is more conducive to ensuring the construction quality; During installation, there is no need to occupy the work site for a large amount of on-site construction, nor is it necessary to erect a floor-standing disk buckle scaffold, which not only reduces the safety risks during the erection process but also eliminates the erection link, thereby effectively improving the work efficiency; At the same time, it shortens the construction period, reduces the cost input of labor, equipment leasing, etc., and significantly reduces the construction cost.

[0045] Please refer to Figures 1 to 4 , this embodiment provides a gallery structure with a rolling support, including a gallery steel bracket 1 and a steel truss gallery structure 2 erected on the top of the gallery steel bracket 1. The gallery steel bracket 1 is connected to the ground concrete foundation through embedded parts. The steel truss gallery structure 2 is spliced by an upper steel beam support frame 21, a lower steel beam support frame 22 and two side steel trusses 23. One side top of the gallery steel bracket 1 is flexibly connected to the bottom of one side of the steel truss gallery structure 2 through a rolling support 3, and the other side top of the gallery steel bracket 1 is rigidly connected to the bottom of the other side of the steel truss gallery structure 2. The moving direction of the rolling support 3 is consistent with the length direction of the steel truss gallery structure 2. Among them, the rolling support 3 includes a rolling part 31 and a fixing part 32 arranged below the rolling part 31. The rolling part 31 can move horizontally relative to the fixing part 32. One side top of the gallery steel bracket 1 is connected to the fixing part 32, and the bottom of one side of the steel truss gallery structure 2 is connected to the rolling part 31.
[0046] The present invention realizes the release of the horizontal displacement of the corridor steel support 1 and the steel truss corridor structure 2 by arranging a rolling support 3 on one side of the steel truss corridor structure 2 for flexible connection with the corridor steel support 1. When encountering horizontal loads such as earthquakes, the rolling part 31 of the rolling support 3 can move horizontally relative to the fixed part 32, enabling the corridor structure to better adapt to the horizontal force, avoiding structural damage caused by limited horizontal displacement, greatly improving the ability of the corridor structure to withstand horizontal loads and seismic resistance, and ensuring the production safety and the safety of personnel's lives and property in earthquake-prone areas. The use of the corridor steel support 1 and the steel truss corridor structure 2 to replace the traditional reinforced concrete support and the corridor body of the brick-concrete structure not only occupies a small area but also significantly reduces the weight of the entire corridor structure, thereby reducing the difficulty and cost of infrastructure construction. It breaks through the limitation of the traditional structure in terms of span. The span of the corridor structure can generally reach about 30 m, and when the belt climbing height increases, the span can even reach more than 50 m. The larger span reduces the setting of the support structure, which not only reduces the construction cost but also reduces the floor area, and at the same time provides greater flexibility for the plane layout of the corridor.
[0047] In one embodiment, the top of one side of the corridor steel support 1 is connected to the fixed part 32 by bolts, and the bottom of one side of the steel truss corridor structure 2 is connected to the rolling part 31 by bolts. Using bolts to connect the corridor steel support 1 and the fixed part 32 of the rolling support 3, and the steel truss corridor structure 1 and the rolling part 31 of the rolling support 3 is relatively simple to operate. Construction workers can complete the installation and disassembly work with conventional tools such as wrenches. In the installation stage, compared with connection methods such as welding, it does not require complex welding equipment and professional welding skills, reducing the construction difficulty and improving the installation efficiency. In the later maintenance, repair or replacement of components, if a certain part of the rolling support 3, the corridor steel support 1 or the steel truss corridor structure 2 is damaged, it can be easily replaced by removing the bolts, reducing the maintenance time and cost.
[0048] Please refer to Figure 5, in one embodiment, the rolling part 31 includes a moving roller 311, a mounting top seat 312, and a pair of first hanging ears 313 provided at the bottom of the mounting top seat 312. On both sides of the moving roller 311, there are roller shafts 3111 respectively passing through the pair of first hanging ears 313. The first hanging ears 313 are provided with first long strip limiting holes 3131 for the roller shafts 3111 to pass through, and the opening direction of the first long strip limiting holes 3131 is consistent with the length direction of the steel truss corridor structure 2. The fixing part 32 includes a mounting base 321 and a pair of second hanging ears 322 provided at the top of the mounting base 321. The second hanging ears 322 are provided with second long strip limiting holes 3221 for the roller shafts 3111 to pass through, and the opening direction of the second long strip limiting holes 3221 is consistent with the length direction of the steel truss corridor structure 2. Among them, the moving roller 311 abuts between the mounting top seat 312 and the mounting base 321 and can roll in the horizontal direction to form a displacement difference between the mounting top seat 312 and the mounting base 321 in the horizontal direction.
[0049] In one embodiment, both sides of the upper steel beam support frame 21 are connected to the tops of the two side steel trusses 23 by bolts, and both sides of the lower steel beam support frame 22 are respectively connected to the bottoms of the two side steel trusses 23 by bolts. The bolt connection makes the assembly of each part of the steel truss corridor structure 2 convenient, facilitating quick installation and disassembly during the construction process. If a certain part is damaged or needs to replace components, it can be operated efficiently. At the same time, the bolt connection can ensure the stability of the structural connection, effectively avoiding relative displacement between components when transmitting loads, and ensuring that all parts of the entire steel truss corridor structure 2 work together to maintain the overall strength and stability of the structure when bearing the loads brought by material transportation and natural environmental loads.
[0050] Of course, in other embodiments, both sides of the upper steel beam support frame 21 can also be connected to the tops of the two side steel trusses 23 by welding or other means, and both sides of the lower steel beam support frame 22 can also be connected to the bottoms of the two side steel trusses 23 by welding or other means. The present invention does not limit this.
[0051] Please refer to Figure 4 , in one embodiment, the upper steel beam support frame 21 includes multiple upper main beams 211 arranged side by side and spaced apart along the length direction of the steel truss corridor structure 2, and upper horizontal support members 212 are provided between two adjacent upper main beams 211. Among them, the upper main beams 211 serve as the main load-bearing members and can bear the gravity loads of the material transportation equipment and the materials themselves from above. The side-by-side and spaced-apart design makes the load distribution more uniform and improves the load-bearing capacity of the structure; the upper horizontal support members 212 enhance the overall stability of the upper steel beam support frame 21, effectively preventing the upper main beams 211 from displacing or deforming in the horizontal direction and resisting the action of horizontal forces such as wind loads.
[0052] Please refer toFigure 4 , in one embodiment, the lower steel beam support frame 22 includes a plurality of lower main beams 221 arranged side by side at intervals along the length direction of the steel truss corridor structure 2. A lower horizontal support member 222 and a plurality of side-by-side spaced lower secondary beams 223 are provided between two adjacent lower main beams 221. Among them, the lower main beam 221 and the upper main beam 211 together form a vertical load-bearing system, bearing the vertical load of the entire corridor structure. Their side-by-side spaced arrangement helps to evenly disperse the load and improve the load-bearing efficiency; the lower horizontal support member 222 cooperates with the lower main beam 221 and the lower secondary beam 223 to enhance the lateral force resistance performance of the lower steel beam support frame 22, ensuring that the structure will not undergo excessive deformation or damage when subjected to horizontal forces; the lower secondary beam 223 increases the local load-bearing capacity of the structure, can better adapt to the layout requirements of the equipment inside the corridor, and works together with the upper steel beam support frame 21 to jointly maintain the overall stability of the steel truss corridor structure 2.
[0053] Please refer to Figure 1 , in one embodiment, the corridor steel support 1 includes a first corridor steel support 11 and a second corridor steel support 12 arranged opposite to each other. The top of the first corridor steel support 11 is flexibly connected to the bottom of one side of the steel truss corridor structure 2 through a rolling support 3, and the top of the second corridor steel support 12 is rigidly connected to the bottom of the other side of the steel truss corridor structure 2. The above rigid-flexible combination connection method effectively solves the displacement problem of the corridor structure under the action of factors such as people walking, vehicle movement, and earthquake. Among them, the rigid connection can ensure the reliable force transmission between the corridor steel support 1 and the steel truss corridor structure 2, ensuring the stability of the structure under normal use conditions; while the flexible connection of the rolling support 3 allows the steel truss corridor structure 2 to have a certain displacement in the horizontal direction, avoiding excessive horizontal loads on the corridor structure and greatly improving the adaptability and safety of the corridor structure.
[0054] Please refer to Figure 2 , Figure 3, in one embodiment, two first mounting seats 111 are arranged at the top of the first corridor steel bracket 11 and are relatively arranged left and right. The two first mounting seats 111 are respectively flexibly connected to the left and right ends of the bottom of one side of the steel truss corridor structure 2 through the rolling supports 3; two second mounting seats 121 are arranged at the top of the second corridor steel bracket 12 and are relatively arranged left and right. The two second mounting seats 121 are respectively rigidly connected to the left and right ends of the bottom of the other side of the steel truss corridor structure 2. The two first mounting seats 111 on the first corridor steel bracket 11 cooperate with the rolling supports 3 to make the displacement of the steel truss corridor structure 2 in the horizontal direction smoother and more stable, reducing the structural deformation caused by uneven displacement. The second mounting seats 121 on the second corridor steel bracket 12 are rigidly connected to the steel truss corridor structure 2, enhancing the reliability of the structural connection part, ensuring the strength and stability of the structural connection part under vertical loads and partial horizontal loads, and ensuring that the entire corridor structure can operate safely and reliably under various working conditions.
[0055] Please refer to Figure 1 , Figure 4 , in one embodiment, a plurality of purlins 24 are arranged in an array at the top of the upper steel beam support frame 21, the bottom of the lower steel beam support frame 22, and the outer sides of the two side steel trusses 23. The plurality of purlins 24 arranged in an array provide convenient connection points for the later installation of other components. Among them, the array layout design enables installers to flexibly select appropriate positions to install components such as reinforcing bars according to actual needs, without having to determine the installation position and method temporarily on site, reducing the uncertainty and complexity during the installation process, thereby improving the installation efficiency. Since the corridor structure may require different types and quantities of strengthening components in different usage scenarios and working conditions, the array distribution of the purlins 24 makes it possible to adapt to these changes. Whether it is to add more reinforcing bars to improve the structural strength or install other functional components, they can be quickly adapted through these preset purlins 24, enhancing the versatility and scalability of the corridor structure.
[0056] Please refer to Figure 6 , in one embodiment, an installation method for a corridor structure with rolling supports includes:
[0057] Step S1, construction preparation, specifically: measuring and setting out lines, completing the installation of the embedded parts of the corridor steel bracket 1, pouring the ground concrete foundation, and preparing the tools, materials, and relevant information required for installing the bracket.
[0058] Among them, when measuring and setting out the lines, professional measuring instruments such as total stations and levels are used to accurately determine the positions of the embedded parts of the corridor steel support 1 on the ground concrete foundation according to the construction drawings. During the measurement process, the data needs to be reviewed multiple times to ensure that the error is controlled within the allowable range to guarantee the installation accuracy of the subsequent corridor steel support 1. When installing the embedded parts, on the determined positions of the embedded parts, the prefabricated embedded parts are accurately installed in place and fixed. At the same time, during the installation process, it is necessary to ensure the firm connection between the embedded parts and the ground concrete foundation to prevent displacement during the concrete pouring process. The relevant materials include construction drawings, construction plans, quality acceptance standards, etc. The construction personnel should be familiar with these materials and clarify the construction requirements and quality standards.
[0059] Step S2: Install the corridor steel support 1, specifically: After the corridor steel support 1 is fabricated in the factory, it is transported to the construction site as a whole and installed.
[0060] Among them, after the corridor steel support 1 is fabricated in the factory, it is transported to the construction site as a whole using a suitable transportation tool. During the transportation process, the corridor steel support 1 should be properly protected to prevent it from being deformed or damaged. After arriving at the construction site, a comprehensive inspection is carried out on the appearance, dimensions, weld quality, etc. of the corridor steel support 1 to ensure that it meets the design requirements and relevant standards. If any quality problems are found, they should be dealt with or replaced in a timely manner. When installing the corridor steel support 1, use a crane to accurately lift the corridor steel support 1 above the position of the embedded part on the ground concrete foundation, and then slowly lower it so that the reserved holes of the corridor steel support 1 are accurately aligned with the bolts on the embedded part, and then preliminarily fixed with nuts. During the installation process, use a crane to accurately lift the corridor steel support 1 above the position of the embedded part on the ground concrete foundation, and then slowly lower it so that the reserved holes of the corridor steel support 1 are accurately aligned with the bolts on the embedded part, and then preliminarily fixed with nuts.
[0061] Step S3: Assemble the side steel truss 23, specifically: After the side steel truss 23 is fabricated in the factory, it is transported to the construction site as a whole and assembled one by one.
[0062] Among them, select a flat and open site at the construction site as the assembly site for the side steel truss 23, and clean and tamp the site to ensure that the site has good bearing capacity. After transporting the side steel truss 23 from the factory to the construction site, inspect its various components, including dimensions, appearance, weld quality, etc.
[0063] Step S4: Assemble the lower steel beam support frame 22, specifically: After each component of the lower steel beam support frame 22 is fabricated in the factory, it is transported to the construction site and assembled with the side steel truss 23.
[0064] Among them, after transporting each component of the lower steel beam support frame 22 from the factory to the construction site, it is inspected to ensure that the quality and dimensions of the components meet the requirements. The inspection content includes the length, cross-sectional dimensions, flatness of the steel beam, as well as the specifications and quantities of the support members and secondary beams. When assembling the lower steel beam support frame 22, according to the design drawings, determine the installation position of the lower steel beam support frame 22 on the side steel truss 23 and make positioning marks; then, hoist each component of the lower steel beam support frame 22 to the installation position one by one and connect it to the side steel truss 23; after completing the connection between the lower main beam 221 and the side steel truss 23, install the lower secondary beam 223 and the lower horizontal support member 222. During the assembly process, pay attention to adjusting the position and angle of the lower steel beam support frame 22 to make it closely cooperate with the side steel truss 23 to form a stable structural system.
[0065] Step S5: Assemble the upper steel beam support frame 21, specifically: After each component of the upper steel beam support frame 21 is fabricated in the factory, it is transported to the construction site and assembled with the side steel truss 23 to form the steel truss corridor structure 2.
[0066] Among them, after transporting each component of the upper steel beam support frame 21 from the factory to the construction site, it is inspected to ensure that the quality and dimensions of the components meet the requirements. The inspection content includes the length, cross-sectional dimensions, flatness of the steel beam, as well as the specifications and quantities of the support members and secondary beams. When assembling the upper steel beam support frame 21, according to the design drawings, determine the installation position of the upper steel beam support frame 21 on the side steel truss 23 and make positioning marks; then, hoist each component of the upper steel beam support frame 21 to the installation position one by one and connect it to the side steel truss 23; after completing the connection between the upper main beam 211 and the side steel truss 23, install the upper horizontal support member 212. During the assembly process, pay attention to adjusting the position and angle of the upper steel beam support frame 21 to make it closely cooperate with the side steel truss 23 to form a stable structural system.
[0067] Step S6: Install the rolling support 3, specifically: After the rolling support 3 is fabricated in the factory, it is transported to the construction site as a whole and installed at the bottom of one side of the steel truss corridor structure 2.
[0068] Among them, after transporting the rolling support 3 from the factory to the construction site, it is comprehensively inspected, including the dimensions, surface quality, rolling performance of the rolling part 31 and the fixed part 32, etc. Check whether the rolling part 31 of the rolling support 3 can move relative to the fixed part 32 flexibly in the horizontal direction to ensure that the quality of the rolling support 3 meets the requirements. When installing the rolling support 3, according to the design requirements, determine the installation position of the rolling support 3 at the bottom of one side of the steel truss corridor structure 2, then accurately align the rolling part 31 of the rolling support 3 with the bottom connection point of the steel truss corridor structure 2, and firmly connect the rolling part 31 of the rolling support 3 to the bottom of the steel truss corridor structure 2 by means of bolts or welding.
[0069] Step S7, hoisting the steel truss corridor structure 2, specifically: hoisting the steel truss corridor structure 2 with the rolling bearing 3 installed as a whole to the top of the corridor steel support 1.
[0070] Among them, when hoisting the steel truss corridor structure 2, use a crane to hoist the steel truss corridor structure 2 with the rolling bearing 3 installed as a whole to the top of the corridor steel support 1; during the hoisting process, the operation must be strictly in accordance with the hoisting operation procedures and commanded by professional commanders; when hoisting, it must be lifted slowly, and the hoisting status of the steel truss corridor structure 2 must be observed to ensure its smooth rise; when approaching the top of the corridor steel support 1, it must be slowly lowered to accurately position the steel truss corridor structure 2 and connect it to the corridor steel support 1. After completing the hoisting operation, conduct a comprehensive acceptance of the entire corridor structure, including structural dimensions, connection quality, verticality, horizontality, etc. After acceptance, clean up the construction site, dismantle temporary facilities, and organize construction tools and materials.
[0071] The above-mentioned corridor structure is manufactured in the factory and assembled on site for installation, with a high degree of industrialization. Compared with the traditional method in which most construction work is carried out on site, it reduces the complicated on-site construction procedures, reduces labor intensity, and is more conducive to ensuring construction quality. During installation, there is no need to occupy the work site for a large amount of on-site construction, nor is there any need to set up ground-based disc-type scaffolding, which not only reduces the safety risks during the erection process, but also eliminates the erection link, thereby effectively improving work efficiency. At the same time, it shortens the construction period, reduces the cost of labor, equipment rental, etc., and greatly reduces the construction cost.
[0072] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
[0073] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
