Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a construction method for a circular building. Background Art

[0002] In building engineering, in order to improve the overall performance and functionality of a building, the building is usually designed as a steel-concrete structure building, that is, a steel structure and a concrete structure are combined to form a composite stress system, which improves the overall bearing capacity, reduces the amount of materials used, and a curtain wall is installed on the steel-concrete structure to improve the aesthetics of the building.

[0003] In the prior art, when constructing a steel structure, a concrete structure, and a curtain wall structure, the construction process is usually simulated in advance, and each part is constructed in sequence according to the simulation results.

However, there are usually deviations between the actual construction conditions of each part and the simulation results. If the construction plan is not adjusted in time and the construction is still carried out according to the simulation results, on the one hand, it will hinder the construction of subsequent structures, affect the construction progress, and reduce the construction efficiency.

[0055] This embodiment provides a construction method for a circular building, as Figure 1 and Figure 2 shown. The construction method for the circular building can timely adjust the construction plan, ensure the construction progress and work efficiency, prevent affecting the construction quality, and avoid causing safety accidents.

[0056] The circular building includes a steel structure 1, a concrete structure and a curtain wall structure. The construction method for the circular building includes the following steps:

[0057] S1. Referring to Figure 1 and Figure 2 shown, determine the construction sequence and construction requirements for the steel structure 1, the concrete structure and the curtain wall structure;

[0058] S2. Referring to Figure 1 shown, use finite element software to establish a main model, the main model including a steel structure 1 model part, a concrete structure model part and a curtain wall structure model part, analyze and calculate the main model to obtain the theoretical deformation amounts of the steel structure 1 model part, the concrete structure model part and the curtain wall structure model part, and accordingly set the construction plans for the steel structure 1, the concrete structure and the curtain wall structure;

[0059] S3. Referring to Figure 1 shown, construct the steel structure 1 according to the existing construction plan;

[0060] S4. Referring to Figure 1As shown, after the construction of the steel structure 1 is completed, use a scanning device to perform three-dimensional scanning on the steel structure 1 and record the position of the steel structure 1, and thus calculate the deformation of the steel structure 1;

[0061] S5. Refer to Figure 1 As shown, determine whether the deformation of the steel structure 1 is consistent with the theoretical deformation of the model part of the steel structure 1. If not, then execute S6 and S7. If so, directly execute S7;

[0062] S6. Refer to Figure 1 As shown, substitute the deformation of the steel structure 1 into the model part of the steel structure 1, and re-analyze and calculate the main model to obtain the theoretical deformation of the new concrete structure model part and the theoretical deformation of the new curtain wall structure model part, and adjust the construction plans of the concrete structure and the curtain wall structure accordingly;

[0063] S7. Refer to Figure 1 As shown, construct the concrete structure according to the existing construction plan;

[0064] S8. Refer to Figure 1 As shown, after the construction of the concrete structure is completed, use a scanning device to perform three-dimensional scanning on the concrete structure and record the position of the concrete structure, and thus calculate the deformation of the concrete structure;

[0065] S9. Refer to Figure 1 As shown, determine whether the deformation of the concrete structure is consistent with the theoretical deformation of the new concrete structure model part. If not, then execute steps S10 and S11. If so, directly execute S11;

[0066] S10. Refer to Figure 1 As shown, substitute the deformation of the concrete structure into the model part of the concrete structure, re-analyze and calculate the main model, and obtain the theoretical deformation of the new curtain wall structure model part again, and adjust the construction plan of the curtain wall structure accordingly;

[0067] S11. Refer to Figure 1 As shown, construct the curtain wall structure according to the existing construction plan.

[0068] When a circular building needs to be constructed, first, the construction staff of the steel structure 1, concrete structure, and curtain wall structure conduct consultations to determine the construction sequence and requirements of the steel structure 1, concrete structure, and curtain wall structure. Use finite element software to establish and analyze the main model, so as to obtain the theoretical deformation of the steel structure 1 model part, the theoretical deformation of the concrete structure model part, and the theoretical deformation of the curtain wall structure model part, that is, obtain the theoretical values of the above three parts. Set the construction plans for the steel structure 1, concrete structure, and curtain wall structure according to the theoretical deformation of the steel structure 1 model part, the theoretical deformation of the concrete structure model part, and the theoretical deformation of the curtain wall structure model part (which is the existing construction plan), and carry out the construction of the steel structure 1 according to this construction plan. After the construction of the steel structure 1 is completed, use scanning equipment to scan the steel structure 1 and record the position information of the steel structure 1, and calculate the deformation of the steel structure 1 based on this (that is, obtain the actual deformation of the steel structure 1 in actual construction).

[0069] Compare the actual deformation of the steel structure 1 with the deformation of the steel structure 1 model part to judge whether they are consistent. If not, substitute the actual deformation of the steel structure 1 into the steel structure 1 model part of the main model, re-analyze and calculate the main model, so as to obtain the new theoretical deformation of the concrete structure model part and the new theoretical deformation of the curtain wall structure model part. Adjust the construction plans of the concrete structure and curtain wall structure according to the latest theoretical deformation of the concrete structure model part and the latest theoretical deformation of the curtain wall structure model part. Then, according to the existing construction plan (that is, the new construction plan after the first adjustment), carry out the construction of the concrete structure; if so, there is no need to adjust the construction plans of the concrete structure and curtain wall structure, and the construction of the concrete structure can be directly carried out. At this time, the existing construction plan is the initial construction plan.

[0070] After the construction of the concrete structure is completed, obtain the deformation of the concrete structure according to the method of obtaining the actual deformation of the steel structure 1 (that is, obtain the actual deformation of the concrete structure). Compare whether the actual deformation of the concrete structure is consistent with the theoretical deformation of the concrete structure model part. If not, according to the treatment method of the steel structure 1, substitute the actual deformation of the concrete structure into the concrete structure model part, calculate and obtain the new theoretical deformation of the curtain wall structure model part, and adjust the construction plan of the curtain wall structure according to the latest theoretical deformation of the curtain wall structure model part. Then, according to the existing construction plan (the new construction plan after the second adjustment), carry out the construction of the curtain wall structure; if so, there is no need to adjust the construction plan after the first adjustment, and the construction of the curtain wall structure can be directly carried out. At this time, the existing construction plan is the construction plan after the first adjustment.

[0071] As can be seen from the above analysis, during the construction process of the entire circular building, first, the circular building is modeled and simulated to obtain the theoretical deformation amounts of each structure. Then, according to the simulation results, the construction of each structure is carried out in sequence. After the construction of each structure is completed, the actual deformation amount of the constructed structure is compared with the theoretical deformation amount. If the two are inconsistent, the actual deformation amount is substituted into the main model for re-analysis and calculation, and the construction plan of the subsequent structure is adjusted in a timely manner according to the calculation results before proceeding with the construction. If the two are consistent, the current existing construction plan is maintained and the construction continues. By monitoring the constructed structures during the entire construction process and comparing the monitoring results with the simulation results, the construction plan can be adjusted in a timely manner according to the actual situation, reducing construction errors, ensuring the construction progress and work efficiency, preventing the impact on construction quality, and avoiding safety accidents.

[0072] Exemplarily, the scanning device includes a three-dimensional laser scanner or a total station, etc.

[0073] Optionally, step S2 specifically includes the following steps:

[0074] S21. Establish a main model using finite element software according to the engineering design. The main model includes a steel structure 1 model part, a concrete structure model part, and a curtain wall structure model part;

[0075] S22. Analyze and calculate the main model in stages according to the construction sequence to obtain the theoretical deformation amounts of the steel structure 1 model part, the concrete structure model part, and the curtain wall structure model part.

[0076] By analyzing and calculating the main model in stages, the theoretical deformation amounts of the steel structure 1 model part, the concrete structure model part, and the curtain wall structure model part can be obtained more accurately, which is conducive to formulating a more perfect construction plan and ensuring the construction quality of the project.

[0077] Optionally, step S2 further includes:

[0078] S23. Analyze and calculate multiple nodes of the main model separately;

[0079] S24. Optimize the construction plan according to the calculation results of the nodes.

[0080] According to the calculation results of multiple nodes, the overall circular building and its individual nodes can be optimized during the construction process, which is conducive to improving the feasibility of the construction plan and ensuring the construction quality of the project.

[0081] It should be noted that usually, the nodes with relatively weak strength of the circular building are analyzed and calculated separately, such as the nodes with large external loads, the nodes with supports, etc.

[0082] Optionally, such asFigure 1 As shown in the figure. The steel structure 1 includes a main body of the steel structure 1, a first temporary support 12 and a second temporary support 13. One end of the first temporary support 12 is connected to the lower surface of the main body of the steel structure 1, and the other end is configured to be set on the ground. The second temporary support 13 is arranged on the upper surface of the main body of the steel structure 1 and is connected to the front end of the main body of the steel structure 1. The second temporary support 13 is used to lift the main body of the steel structure 1 vertically upward. By arranging the first temporary support 12 below the main body of the steel structure 1, the main body of the steel structure 1 can be supported, thereby raising the vertical height of the main body of the steel structure 1, facilitating the splicing construction of the main body of the steel structure 1. At the same time, by arranging the second temporary support 13, the front end of the main body of the steel structure 1 can be lifted, so that the main body of the steel structure 1 maintains a slightly lifted posture, which can increase the longitudinal stability of the main body of the steel structure 1, thereby reducing the risk of overturning and ensuring the construction safety.

[0083] Optionally, the second temporary support 13 includes a support frame body and a connecting member. The support frame body is arranged on the main body of the steel structure 1 and extends vertically. One end of the connecting member is connected to the support frame body, and the other end is connected to the front end of the main body of the steel structure 1, and is used to lift the main body of the steel structure 1 upward. By arranging the support frame body and the connecting member, the connecting member lifts the main body of the steel structure 1 upward, thereby reducing the structural deformation of the main body of the steel structure 1 caused by the cantilever effect, ensuring the overall stability of the structure. At the same time, the connecting member transfers part of the load borne by the main body of the steel structure 1 to the support frame body, which can optimize the force distribution of the structure.

[0084] Exemplarily, the support frame body includes a portal frame, and the connecting member includes a steel wire rope.

[0085] Optionally, step S3 specifically includes the following steps:

[0086] S31. Erect the main body of the steel structure 1, the first temporary support 12 and the second temporary support 13 according to the calculation results of the main model;

[0087] S32. Conduct a simulation analysis on part of the main body of the steel structure 1 in the area with a larger span to obtain the downward deflection of the main body of the steel structure 1 in the area with a larger span;

[0088] S33. Judge whether the downward deflection of the main body of the steel structure 1 in the area with a larger span is greater than l0 / 400 (l0 is the span of the main body of the steel structure 1). If so, execute S34; if not, execute S4;

[0089] S34. Set the first temporary support 12 and the second temporary support 13 in this area.

[0090] By simulating and analyzing part of the main body of the steel structure 1 in a relatively large-span area, the downward deflection of the main body of the steel structure 1 in this area can be obtained, so as to judge whether a temporary support structure needs to be set for the main body of the steel structure 1 in this area, thereby preventing the main body of the steel structure 1 in the large-span area from buckling and deforming, enhancing the overall stability of the main body of the steel structure 1, and ensuring the safety and construction quality of the construction.

[0091] Optionally, step S7 specifically includes the following steps:

[0092] S71. Remove the first temporary support 12 and the second temporary support 13, and erect a permanent support, and the main body of the steel structure 1 is arranged on the permanent support;

[0093] S72. Use a scanning device to perform a three-dimensional scan on the steel structure 1 again and record the position of the steel structure 1, so as to calculate the latest deformation amount of the steel structure 1;

[0094] S73. Judge whether the latest deformation amount of the steel structure 1 is consistent with the theoretical deformation amount of the latest steel structure 1 model part. If not, execute S74 and S75. If so, directly execute S75;

[0095] S74. Substitute the latest deformation amount of the steel structure 1 into the steel structure 1 model part, and re-analyze and calculate the main model to obtain the deformation amounts of the latest concrete structure model part and the curtain wall structure model part, and adjust the construction plans of the concrete structure and the curtain wall structure accordingly;

[0096] S75. Construct the concrete structure according to the existing construction plan.

[0097] After removing the first temporary support 12 and the second temporary support 13, erect a permanent support and arrange the main body of the steel structure 1 on the permanent support, which can provide better support for the main body of the steel structure 1 to prevent it from overturning and shifting. Moreover, after removing the first temporary support 12 and the second temporary support 13, calculate the actual deformation amount of the steel structure 1 again, and compare the actual deformation amount with the theoretical deformation amount of the new steel structure 1 model part, so as to update the construction plans of the subsequent structures in a timely manner, enhance the feasibility and adaptability of the construction plans, and ensure the construction quality of the project.

[0098] Optionally, step S11 specifically includes the following steps:

[0099] S111. The curtain wall structure includes multiple curtain wall sub-parts, and install multiple curtain wall sub-parts in sequence according to the latest calculation results of the main model;

[0100] S112. Use a scanning device to perform a three-dimensional scan on the installed curtain wall sub-parts every time a curtain wall sub-part is installed, and record the position of the curtain wall sub-part until all the curtain wall sub-parts are installed;

[0101] S113. Calculate the deformation amount of the curtain wall structure based on the position of the curtain wall branch, and determine whether the deformation amount of the curtain wall structure is consistent with the theoretical deformation amount of the new curtain wall structure model part. If not, execute S114 and S115; if so, directly execute S115;

[0102] S114. Substitute the deformation amount of the curtain wall structure into the curtain wall structure model part, re-analyze and calculate the main model to obtain the deformation amount of the latest curtain wall structure model part, and adjust the construction plan of the process accordingly;

[0103] S115. Perform the construction of subsequent processes according to the existing construction plan.

[0104] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
