Description

Technical Field

[0001] The invention relates to the field of building construction, in particular to a method for constructing a single-side tireless frame on the outer side of a ring truss. Background Art

[0002] Steel structure truss construction technology, as a treasure in the field of modern architecture, cleverly utilizes the dual advantages of high strength and light weight of steel, making it possible to efficiently build large-span and complex structures. Through the integration of precise design and exquisite welding technology, it not only ensures the stability and safety of the structure, but also shines in large-scale engineering projects such as gymnasiums, bridges, and industrial plants, showing its incomparable practicality and aesthetic value.

[0003] During the installation of high-area trusses, faced with large volume, heavy weight, and unstable construction environment, traditional construction mostly adopts bilateral support, setting up a large number of support structures on both sides of the components. The support structure is complex, and the construction site occupies a large space. Too many support structures bring a lot of construction obstacles and material waste, and the economic cost is high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for constructing a single-sided tireless frame on the outer side of a ring truss in view of the deficiencies of the above-mentioned prior art. The method for constructing a single-sided tireless frame on the outer side of a ring truss utilizes its own structural system and adopts a single-sided outer side supportless method, abandoning the traditional practice of setting a large number of support structures on both sides of the component. According to the principle of priority construction on the center of gravity side, the component installation sequence is optimized and improved, so that the center of gravity of the structure is always kept inside, and thus the installation of the complete structure is completed to form a complete force system. In addition, during the installation process of the inner ring truss, the outer ring truss and the crossbeam, the original components can be supported independently, and a number of installation stabilization measures are adopted to improve the force transmission system and keep the center of gravity inside.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a method for constructing a single-side tireless frame on the outer side of a ring truss, comprising the following steps: Step 1: Conduct preliminary construction simulation analysis and center of gravity distribution analysis on the front construction structure installation, inner structure installation, outer structure installation, and beam installation to ensure that the center of gravity is always kept inward during installation.

[0006] Step 2: Based on ANSYS finite element simulation analysis, the structural components are designed in depth to determine the installation sequence, installation location, installation form, and installation measures; the installation sequence prioritizes the construction on the center of gravity side, based on the pre-construction structure, the inner structure is installed first, followed by the outer structure, and finally the beam is installed.

[0007] Step 3: Based on the in-depth design, install the inner temporary support frame, universal hinge support and main structure, and carry out construction preparation work.

[0008] Step 4: After completing the above construction, install the inner ring truss and the inner V-column in turn.

[0009] Step 5: Install the outer V-column. After installation, use tie steel pipes to tie the inner and outer V-columns to form an integral internal and external force transmission system, and install the outer ring truss.

[0010] Step 6: The outer ring truss and the inner ring truss are connected and installed through the cross beam.

[0011] Step 7: After the crossbeam connection is installed, the high-vanadium cable connecting components are installed, and high-vanadium cables are used for prestressing between V-columns.

[0012] Furthermore, the center of gravity of the inner ring truss and the outer ring truss is kept inward during the entire installation process, and the inner temporary support frame is used for temporary support during the entire installation process to transmit force to the main structure.

[0013] Preferably, the inner ring truss and the outer ring truss are installed in sections, and each section of the ring truss has a different cross-section and weight. Through simulation analysis and structural calculation, it is confirmed that the timing of installation and insertion of the outer ring truss is after the three sections of the inner ring truss are installed, thereby reducing the outward displacement of the center of gravity when installing the outer ring truss, ensuring safety during the installation process, and effectively avoiding outward instability of the structure.

[0014] Furthermore, in step three, the construction preparation work is specifically the installation of the front construction structure: the front construction structure includes a universal hinge support, a main structure, and an inner temporary support frame; the main structure includes a step platform board arranged on one side thereof, and the step platform board extends toward the inner temporary support frame; the inner temporary support frame is installed on the step platform board of the main structure, and the universal hinge support is installed on the table top of the main structure.

[0015] Furthermore, in step three, a steel structure support force transmission system is adopted at the bottom of the inner temporary support cradle; the steel structure support force transmission system includes structural embedded plate A, support distribution beam, support column, and structural embedded plate B; a support distribution beam is arranged at the bottom of the inner temporary support cradle, a support column is arranged on the side of the support distribution beam away from the main structure, the side of the support distribution beam close to the main structure is connected to a step grandstand plate through the structural embedded plate A, and the bottom of the support column is connected to another step grandstand plate through the structural embedded plate B.

[0016] Furthermore, in step three, embedded steel parts are provided on the main structure table top, and the universal hinge support is welded to the main structure table top through the embedded steel parts; and the universal hinge support is temporarily fixed by a support limit plate.

[0017] Furthermore, in step four, the inner ring truss is hoisted and installed to the top of the inner temporary support frame; the inner V-pillar is hoisted, the lower end of the inner V-pillar is installed to the universal hinge support, the upper end support is connected to the bottom of the inner ring truss, and the upper end support of the inner V-pillar is connected in place and then welded.

[0018] Furthermore, in step five, the outer V-pillar is hoisted, and the lower end of the outer V-pillar is installed to the universal hinge support. The upper position of the outer V-pillar and the lower position of the inner V-pillar are tied together by a tie steel pipe; the outer ring truss is hoisted and installed to the top of the outer V-pillar.

[0019] Furthermore, in step five, the outer V-pillar and the inner V-pillar are connected at the joint by flat seams and fixed by welding; after the outer ring truss is installed in place, it is fixed by welding.

[0020] Furthermore, the method also includes step eight: completing the jointing of the inner ring truss and the outer ring truss; removing the tie steel pipes; and unloading and removing the inner temporary support frame and the support limit plate.

[0021] The present invention has the following beneficial effects: 1. This application utilizes its own structural system and adopts a single-sided outer side unsupported method, abandoning the traditional practice of setting up a large number of support structures on both sides of the components. According to the principle of priority construction on the center of gravity side, the component installation sequence is optimized and improved, so that the center of gravity of the structure is always kept inward, and the installation of the complete structure is completed to form a complete force system. In addition, during the installation of the inner ring truss, the outer ring truss and the crossbeam, the original components can be supported independently, and a number of installation stabilization measures are adopted to improve the force transmission system and keep the center of gravity inward. Compared with traditional practices, it can not only effectively reduce the space occupied on the construction site, avoid construction obstacles and material waste caused by too many support structures, but also greatly save economic costs, saving 65% of economic costs compared to traditional installation methods.

[0022] 2. Through ANSYS finite element structural verification, the applicability of its installation method to single-sided unsupported outer side and the pre-use conditions of the installation method were confirmed, while ensuring that the components can avoid construction risks to the greatest extent during the installation process; the overall implementation method is gradually completed in the order of "construction simulation-deepening design-on-site construction", and the feasibility of the plan and the deepening of measures are confirmed through structural calculation and installation construction simulation analysis.

[0023] 3. Using tie-tied round tubes as installation measures can improve the force system, form a triangular force transmission, and further improve the safety and stability of the structure; after the crossbeam connection is installed, the high-vanadium cable connection components are installed, and high-vanadium cable prestressing is used between the V-columns. The high-vanadium cable connection components are permanent structures used to improve the support safety and stability of the V-columns.

[0024] 4. Tie-off steel pipes are temporary measures. After the V-columns are prestressed with high vanadium cables, the tie-off steel pipes are removed. The inner temporary support frame and support limit plate are temporary measures. After the complete structure is formed, the inner temporary support frame and support limit plate are unloaded and removed. The removal stage is convenient, fast, economical and practical, and further reduces material loss and waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A method for constructing a single-side tireless frame on the outer side of a ring truss comprises installing a front construction structure, installing an inner structure, installing an outer structure, and installing a crossbeam.

[0039] Pre-construction structure installation Figure 1-2 As shown, the front construction structure includes a universal hinge support 1, a main structure 8, and an inner temporary support frame 7; the main structure includes a stepped grandstand board arranged on one side thereof, and the stepped grandstand board extends toward the inner temporary support frame 7 to support the inner temporary support frame 7.

[0040] Install the inner temporary support frame 7 to the stepped platform board of the main structure 8, and install the universal movable hinge support 1 on the main structure platform.

[0041] The inner structure is installed as Figure 3-4 As shown, the inner structure includes an inner V-pillar 2 and an inner ring truss 3; the inner ring truss 3 is hoisted and installed to the top of the inner temporary support frame 7; the inner V-pillar 2 is hoisted, and the lower end of the inner V-pillar 2 is installed to the universal hinge support, and the upper end support is connected to the bottom of the inner ring truss 3.

[0042] External structure installation Figure 5-6 As shown, the outer structure includes an outer V-column 4, a tie steel pipe 6, and an outer ring truss 5; the outer V-column 4 is hoisted, and the lower end of the outer V-column 4 is installed to a universal hinge support, and the upper position of the outer V-column and the lower position of the inner V-column are tied together by a tie steel pipe; the outer ring truss is hoisted and installed to the top of the outer V-column.

[0043] Beam installation Figure 7 As shown, the cross beam 13 is installed, and both ends of the cross beam are respectively connected to the inner ring truss and the outer ring truss.

[0044] This construction method adopts a single-side outer side unsupported method, abandoning the traditional practice of setting up a large number of supporting structures on both sides of the components. According to the principle of priority construction on the center of gravity side, the component installation sequence is optimized and improved. Specifically, on the basis of the installation of the pre-construction structure, the inner structure is installed first, then the outer structure is installed, and finally the crossbeam is installed, so that the center of gravity of the structure is always kept inward, and thus the installation of the complete structure is completed to form a complete force system. In addition, during the installation of the inner ring truss, the outer ring truss and the crossbeam, the original components can be supported independently, and a number of installation stabilization measures are adopted to improve the force transmission system and keep the center of gravity inward.

[0045] In one of the preferred embodiments, by performing structural calculations and installation construction simulation analysis on the installation, the feasibility of the plan and the deepening of measures are confirmed, and the overall implementation method is gradually completed in the order of "construction simulation-deepening design-on-site construction".

[0046] Step 1: Conduct preliminary construction simulation analysis and center of gravity distribution analysis on the front construction structure installation, inner structure installation, outer structure installation, and beam installation to ensure that the center of gravity is always kept inward during installation.

[0047] The construction simulation analysis and center of gravity distribution analysis adopt ANSYS finite element simulation analysis. Through ANSYS finite element simulation analysis, the structure is verified, the feasibility and safety of the method are determined, and data support is provided for the in-depth design of the structure.

[0048] On the basis of the installation of the pre-construction structure, the center of gravity position is calculated for the three working conditions of inner structure installation, outer structure installation, and beam installation. After extracting data through simulation analysis, the data details are shown in Table 1 below: Table 1 Working conditions Center of gravity Distance from the center of the universal hinge support (m) Internal structure installation Inner V-pillar 7.136 External structure installation Inner V-pillar 2.651 Beam installation Inner V-pillar 2.471 The inner structure installation conditions are as follows: Figure 3-4 As shown, the overall center of gravity of the inner ring truss falls on the inner side, and the center of gravity is 7.136m away from the center of the universal hinge support. In this working condition, the inner structure relies on the inner temporary support frame for support and transmits force to the main structure.

[0049] External structure installation conditions Figure 5-6 As shown in the figure, after the installation of the outer ring truss is completed, the center of gravity of the structure still remains on the inside, and the center of gravity is 2.651m away from the center of the universal hinge support; in this working condition, the outer ring truss is unilaterally high-altitude without a supporting tire frame, which falls directly on the outer V-column. The center of gravity of the overall structure is inward, and the structural stiffness of the inner V-column and the outer V-column can support the installation of the inner ring truss and the outer ring truss, and form an overall complete force transmission system to ensure the safety and reliability of the structure.

[0050] Furthermore, the installation position of the tie steel pipe is determined through ANSYS finite element simulation analysis. The use of tie steel pipe as the installation measure rod can improve the force system. The tie steel pipe is used to tie the outer V-column and guide the force to the inside, forming a triangular force transmission, which improves the structural stability and safety.

[0051] Furthermore, preferably, the inner ring truss and the outer ring truss are installed in sections, and each section of the ring truss has a different cross-section and weight. Through simulation analysis and structural calculation, it is confirmed that the timing of installation and insertion of the outer ring truss is after the inner ring truss completes the installation of 3 sections, thereby reducing the outward offset of the center of gravity when installing the outer ring truss, ensuring safety during the installation process, and effectively avoiding outward instability of the structure.

[0052] Beam installation conditions Figure 7 As shown, the two ends of the beam are connected to the inner ring truss and the outer ring truss respectively. This working condition completes the connection of the complete structure. The center of gravity of the complete structure still remains on the inside, and the center of gravity is 2.471m away from the center of the universal movable hinge support.

[0053] Through ANSYS finite element structural verification, the applicability of the single-sided tireless frame construction method on the outer side of the ring truss to single-sided unsupported construction and the prerequisite conditions for the installation method were confirmed, while ensuring that the construction risks of the components can be avoided to the greatest extent during the installation process.

[0054] Step one completed the construction simulation. Through ANSYS finite element simulation analysis, the center of gravity position of each working condition was calculated to provide data support for the subsequent in-depth design of the structure. The results showed that the installation of each construction structure can ensure that the center of gravity position of the structure is always close to the inside. The optimized installation sequence forms a complete force system, and the construction method is feasible and safe.

[0055] Furthermore, step two: based on ANSYS finite element simulation analysis, the structural components are designed in depth to determine the installation sequence, installation location, installation form, and installation measures; the installation sequence prioritizes the construction on the center of gravity side, based on the front construction structure, the inner structure is installed first, followed by the outer structure, and finally the beam is installed.

[0056] This step completes the in-depth design and determines the installation sequence, installation location, installation form, and installation measures. Among them, the installation sequence prioritizes construction on the center of gravity side to ensure that the center of gravity remains inward during the entire installation process of the inner and outer ring trusses. At the same time, a number of installation stabilization measures are used to further improve the force transmission system and keep the center of gravity inward.

[0057] Further, step three: based on the in-depth design, install the inner temporary support frame, the universal hinge support and the main structure, and carry out construction preparation work.

[0058] The construction preparation work specifically includes the installation of the pre-construction structure: Figure 1-2 As shown, the front construction structure includes a universal hinge support 1, a main structure 8, and an inner temporary support frame 7; the main structure includes a stepped grandstand board arranged on one side thereof, and the stepped grandstand board extends toward the inner temporary support frame 7 to support the inner temporary support frame 7.

[0059] Install the inner temporary support frame 7 to the stepped platform board of the main structure 8, and install the universal movable hinge support 1 on the main structure platform.

[0060] Preferably, if Fig. 9 As shown, the bottom of the inner temporary support frame 7 adopts a steel structure support force transmission system, which has excellent vertical load support capacity and anti-overturning ability.

[0061] Among them, the steel structure support force transmission system includes structural embedded plate A9, support distribution beam 10, support column 11, and structural embedded plate B14.

[0062] Preferably, the structural embedded plate A9 and the structural embedded plate B14 are embedded in the stepped platform plate in advance to achieve the welding connection between the inner temporary supporting frame and the stepped platform plate.

[0063] Preferably, a support distribution beam 10 is provided at the bottom of the inner temporary support frame 7, and a support column is provided on the side of the support distribution beam 10 away from the main structure. The structural force is transmitted to the stepped grandstand plate of the main structure through the support distribution beam 10 and the support column 11.

[0064] Preferably, the side of the supporting distribution beam 10 close to the main structure is connected to a corresponding step platform plate through a structural embedded plate A9, and the bottom of the supporting column is connected to a corresponding step platform plate through a structural embedded plate B14.

[0065] Preferably, the inner temporary supporting tire frame 7 is connected to the supporting distribution beam 10 by welding.

[0066] Preferably, the supporting distribution beam 10 is connected to the supporting column by welding.

[0067] Preferably, the supporting distribution beam 10 is welded to the structural embedded plate A9.

[0068] Preferably, the support column 11 is connected to the structural embedded plate B14 by welding.

[0069] Furthermore, if Figure 8As shown in the figure, embedded steel parts are provided on the main structure tabletop. The embedded steel parts are buried before concrete pouring. The universal movable hinge support is welded to the main structure tabletop through the embedded steel parts. According to the design requirements, during the installation process, a high-precision measuring instrument is required to check its position, elevation, and angle before installation. At the same time, the support limit plate 12 is used to temporarily fix the universal movable hinge support 1 to limit the structural deformation and ensure that the installation process of the inner ring truss and the outer ring truss remains in a rigid state.

[0070] Preferably, the universal movable hinge support 1 is installed on the main structure tabletop by welding.

[0071] Further, after completing the construction preparation work, the inner structure installation is prioritized.

[0072] Step 4: After completing the above construction, the inner ring truss and the inner V-column are installed successively.

[0073] This step is the installation of the inner structure. As Figure 3-4 shown, the inner structure includes the inner V-column 2 and the inner ring truss 3. The inner ring truss 3 is hoisted and installed on the top of the inner temporary support bracket 7. The inner V-column 2 is hoisted, and the lower end of the inner V-column 2 is installed on the universal movable hinge support, and the upper end is supported and connected to the bottom of the inner ring truss 3.

[0074] As Figure 3 shown, when hoisting the inner ring beam, a 500T large crawler crane is required for hoisting construction. It is installed on the top of the inner temporary support bracket for position control, and after measurement and review, it is installed at the designed position.

[0075] As Figure 4 shown, the lower end of the inner V-column is hinged, and after the upper end is supported and connected in place, welding is carried out.

[0076] Further, after completing the installation of the inner structure, the outer structure installation is carried out.

[0077] Step 5: Install the outer V-column. After completion, tie steel pipes are used to tie the inner V-column and the outer V-column to form an internal and external integral force transmission system, and then install the outer ring truss.

[0078] This step is the installation of the outer structure. As Figure 5-6 shown, the outer structure includes the outer V-column 4, the tie steel pipe 6, and the outer ring truss 5. The outer V-column 4 is hoisted, and the lower end of the outer V-column 4 is installed on the universal movable hinge support. The upper position of the outer V-column and the lower position of the inner V-column are tied by the tie steel pipe. The outer ring truss is hoisted and installed on the top of the outer V-column.

[0079] Furthermore, the use of tie steel pipes as installation rods can improve the force system. The tie steel pipes tie the outer V-columns, and the force is directed to the inside, forming a triangular force transmission, which further improves the structural safety.

[0080] Preferably, the outer V-pillar and the inner V-pillar are connected at a flat seam and fixed by welding.

[0081] like Figure 6 As shown, the outer ring truss 5 is hoisted and installed on the top of the outer V-pillar 4, and the position is controlled. After measurement and verification, it is installed to the designed position. After installation in place, it is fixed by welding.

[0082] The outer ring truss has a single-sided high-altitude unsupported frame, which falls directly on the outer V-column, saving the outer V-column support frame, effectively reducing the space occupied on the construction site, and avoiding construction obstacles caused by too many supporting structures. In addition, the structural rigidity of the outer V-column and the inner V-column can support the installation of the inner ring truss and the outer ring truss, forming an overall complete force transmission system.

[0083] Furthermore, after the outer structure is installed, the crossbeam is installed.

[0084] Step 6: The outer ring truss and the inner ring truss are connected and installed through the cross beam.

[0085] like Figure 7 As shown, the crossbeam connection installation is performed, and the two ends of the crossbeam are respectively connected to the inner ring truss and the outer ring truss.

[0086] Preferably, the crossbeam connection and installation method is a welding connection method.

[0087] The above steps complete the construction of the single-sided high-altitude unsupported tire frame on the outer side of the ring truss. This construction improves the installation sequence. The installation sequence prioritizes the construction on the center of gravity side. Based on the pre-construction structure, the inner structure is installed first, followed by the outer structure, and finally the crossbeam. The center of gravity of the inner and outer ring trusses is kept inward during the entire installation process. The inner temporary support tire frame is used for temporary support during the entire installation process to transmit force to the main structure.

[0088] In one preferred embodiment, further: Step 7: After the crossbeam connection is installed, the high-vanadium cable connecting components are installed, and high-vanadium cables are used for prestressing between V-columns.

[0089] The high-vanadium cable connecting member is a permanent structure used to improve the support safety and stability of the V-pillar.

[0090] Step 8: Complete the jointing of the inner ring truss and the outer ring truss; remove the tie steel pipe; unload and remove the inner temporary support frame and support limit plate.

[0091] The inner ring truss and the outer ring truss are connected; Fig.10 As shown, the inner ring truss and the outer ring truss are connected by the inner and outer truss interlacing construction node 15.

[0092] The tie steel pipe is a temporary measure. After the V-columns are prestressed with high vanadium cables, the tie steel pipe is removed.

[0093] The inner temporary support frame and support limit plate are temporary measures. After the complete structure is formed, the inner temporary support frame and support limit plate will be unloaded and removed.

[0094] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The preferred embodiments of the present invention are described in detail above; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
