Description

Technical Field

[0001] The invention relates to the technical field of curtain wall structure construction, in particular to an assembled construction method for a curved aluminum plate curtain wall. Background Art

[0002] With the development of Chinese society and the advancement of science and technology, more and more personalized buildings have gradually come into people's sight. The facades of these personalized building projects are mostly built by special-shaped building curtain walls. In order to highlight the individuality of the building, architects have integrated elements such as ellipses, broken lines, paraboloids, hyperboloids or free-form surfaces into the external protective structure of the personalized building, making the overall lines of these personalized buildings more beautiful and dynamic, revealing the breath of fashion and the spirit of the times of people's pursuit of individuality in today's society. The curtain wall is the exterior wall of the building. It is composed of various strong, light and beautiful structural frame materials and panels, making the building a beautiful, multifunctional and safe exterior wall. It is generally used as a decorative wall in modern large-scale high-rise buildings. Curved curtain walls not only put forward higher requirements for curtain walls, but also the construction errors of the main structure of the building are often large.

[0003] In the patent document with application number "CN202311361674.X" and titled "A method for prefabricated installation of a hyperbolic aluminum curtain wall", it is recorded as follows: "It includes the following specific steps: S1. According to the bending radius of the outer surface of the curtain wall indicated in the drawing of the hyperbolic aluminum curtain wall, a curtain wall skin model is established. On the basis of the skin model, according to the node diagram and the keel grid, the keel finished surface skin and keel intersection points are drawn; S2. Based on S1, the keel surface centerline and keel model are generated by using BIM technology, and the keel bending radius at different parts is extracted; S3; S4; S5; S6. The diamond-shaped aluminum veneer is made by single-curving thick aluminum veneer. This construction method ensures that the keel finished surface meets the design effect after the keel is installed by determining the precise bending radius of the curved keel, twisting the keel joint to ensure the uniformity of the keel joint finished surface, and transforming the conventional single keel installation method into the overall hoisting of the ground plate welding, which has high precision, shortened construction period and reduced cost." Although the prefabricated installation construction method of the hyperbolic aluminum curtain wall provided in the patent document has advantages such as shortened construction period, it is relatively insufficient in terms of error control and efficiency during the construction process, and still needs further improvement.

[0004] For example, in the patent document with application number "CN202310694838.4" and name "A method for prefabricated construction of curved aluminum plate curtain wall based on BIM technology", it is recorded as follows: "The steps of the present invention are: Step 1, establish the initial model of the curtain wall according to the design drawings, and extract the corresponding coordinate points for main structure construction and embedded parts installation; Step 2, use a three-dimensional scanner to scan the main structure and remeasure the structural coordinates; Step 3, use BIM parametric software Grasshopper to classify the details of the curtain wall mesh surface; Step 4, perform prefabricated processing and production of curtain wall unit panels according to the content and the proposed construction plan; Step 5, extract the installation module coordinates according to the curtain wall model block for entity lofting; Step 6, perform fire protection, grounding, closing and other detailed processing to complete the entity installation of the curtain wall. The present invention can realize data coordination and dynamic control from design to construction, and can also achieve the purpose of precise control of the entire process of design and construction, greatly improving the construction efficiency of curved curtain walls." Although the prefabricated construction method of curved aluminum curtain wall based on BIM technology provided in the patent document constructs an initial model of the curtain wall based on BIM technology, it does not update the initial model of the curtain wall according to the actual installation situation, which affects the subsequent maintenance of the curved aluminum curtain wall and still needs further improvement.

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example: Figure 1 As shown, this embodiment provides a method for assembling a curved aluminum curtain wall, comprising the following steps: S1. Obtain design drawings, build curtain wall models according to the design drawings, and then sequence the construction of the curtain wall models.

[0020] The construction sequencing process is as follows: Extract curtain wall model blocks from the curtain wall model; Then, the blocks of each curtain wall model are numbered, sorted and assigned characteristics; The numbering is carried out in accordance with the construction sequence of the design drawings, and the feature assignment includes assigning association information of adjacent curtain wall model blocks and positioning information of corresponding curtain wall model blocks.

[0021] In this embodiment, it should be noted that the curtain wall model can be constructed by including but not limited to constructing the curtain wall model based on BIM technology. As an implementation method, the curtain wall model is divided into curved aluminum plate curtain wall monomers, that is, a single curved aluminum plate. This embodiment can effectively facilitate subsequent orderly installation by numbering and characterizing each curved aluminum plate, avoid installation misalignment of the curved aluminum plate, ensure installation reliability, save installation time, and improve installation efficiency. The features include but are not limited to position identification codes of curved aluminum plates and adjacent curved aluminum plates, such as 0000+0001+01, where 0000 is the installation code of the curved aluminum plate, 0001 is the installation code of the adjacent curved aluminum plate, and 01 is a position code, such as located on the left side of 0000.

[0022] S2. Assemble and construct the curved aluminum curtain wall according to the construction sequence, scan the curtain wall body, calculate the construction error, correct the curved aluminum curtain wall monomer and build the actual model.

[0023] Among them, the process of assembling and constructing the curved aluminum curtain wall according to the construction sequence is as follows: Mark the corresponding construction sequence information on the processed curved aluminum curtain wall monomer; Install the curved aluminum panel curtain wall units step by step according to the construction sequence information.

[0024] In this embodiment, it should be noted that the sorting information is marked on the curved aluminum plate curtain wall monomer to facilitate subsequent sorting and installation.

[0025] In addition, before the assembly and construction of the curved aluminum curtain wall is carried out according to the construction sequence, it also includes: Lay out the lines, and after that, install the clamps according to the positioning lines of the keel installation; After completing the installation of the clamp and the base, start installing the keel; After the keel is installed, install and fix the curved aluminum panel curtain wall monomer adapter. The adapter is firmly connected to the keel through bolts and can slide and move along the keel for adjustment. After the keel is firmly installed and inspected and accepted, carefully check the installation positioning of the adapter to ensure accurate positioning before starting to install the curved aluminum panel curtain wall unit.

[0026] In this embodiment, it should be noted that the layout can be carried out by methods including but not limited to the polar coordinate method (for irregular shapes, the layout is measured and laid out based on the plan and curtain wall model, and then the actual measurement and layout are carried out at the construction site based on the obtained data). In addition, when installing the keel, the construction reference keel is determined according to the construction sequence, and then the keel construction is carried out from top to bottom in sequence according to the grid size requirements.

[0027] In addition, when installing the curved aluminum plate curtain wall monomers, it is preferred to install the curved aluminum plate curtain wall monomers in sequence according to the sorting information. At the same time, during the installation process, check the assigned features to ensure that the relationship between adjacent curved aluminum plate curtain wall monomers is correct to avoid installation errors. As an implementation method, after the first curved aluminum plate curtain wall monomer is installed, the second curved aluminum plate curtain wall monomer is installed, and the feature information on the first curved aluminum plate curtain wall monomer and the second curved aluminum plate curtain wall monomer is checked at the same time to ensure that the installation positions of the first curved aluminum plate curtain wall monomer and the second curved aluminum plate curtain wall monomer are correct.

[0028] Furthermore, the calculation formula of the construction error is: , where is the height error value of the curved aluminum curtain wall unit. is the preset overlap range, is the actual overlap range, is the repetition range, It is the distance between adjacent curved aluminum panel curtain wall units.

[0029] The process of modifying the curved aluminum curtain wall monomer is as follows: Obtaining the calculated construction error and comparing it with a preset construction error threshold; If it is within the error threshold, no adjustment will be made to the modified curved aluminum panel curtain wall monomer; If it is not within the threshold, reinstall the corrected curved aluminum panel curtain wall unit.

[0030] In addition, constructing the actual model means replacing the corresponding curtain wall model blocks in the curtain wall model with the installation information of the actually installed positive curved aluminum panel curtain wall monomer to construct the actual model.

[0031] In this embodiment, it should be noted that, through the calculation of construction errors and the correction of curved aluminum plate curtain wall monomers, the correlation between curved aluminum plate curtain wall monomers can be made closer, the stability and firmness are higher, and the overlap error of curved aluminum plate curtain wall monomers is controllable. As an implementation method, the preset construction error threshold can be set to within 0.2mm, that is, when the construction error of the positive curved aluminum plate curtain wall monomer is less than 0.2mm, the positive curved aluminum plate curtain wall monomer is adjusted. If the construction error of the positive curved aluminum plate curtain wall monomer is greater than or equal to 0.2mm, it is necessary to reinstall and adjust the positive curved aluminum plate curtain wall monomer, and recalculate and correct the construction error until the construction error of the positive curved aluminum plate curtain wall monomer is less than 0.2mm.

[0032] In addition, after the curved aluminum plate curtain wall monomer is corrected, the adjacent positive curved aluminum plate curtain wall monomer can be fixed for a second time. The secondary fixing method includes but is not limited to welding. Glue injection can also be used to increase the stability and correlation of the positive curved aluminum plate curtain wall monomer.

[0033] S3. Install all curved aluminum curtain wall units step by step, and analyze the actual model constructed in real time to complete the prefabricated construction of the curved aluminum curtain wall.

[0034] The real-time analysis of the content of the constructed actual model refers to analyzing the technical information of the constructed actual model according to the design technical requirements to ensure that the constructed actual model meets the design technical requirements.

[0035] In addition, it also includes the installation of decorative strips and finishing cleanup after the installation of all curved aluminum panel curtain wall units is completed.

[0036] In this embodiment, it should be noted that by gradually installing all the curved aluminum plate curtain wall monomers and analyzing the constructed actual model in real time, it can be effectively ensured that the installation of the curved aluminum plate curtain wall monomers meets the design technical requirements, and the actual model is used to truly reflect the installation status of the curved aluminum plate curtain wall monomers. After the curved aluminum plate curtain wall is completed, a real curved aluminum plate curtain wall model can be obtained, which is convenient for subsequent data storage and later maintenance.

[0037] The method for prefabricated construction of a curved aluminum plate curtain wall provided by the present invention obtains design drawings, constructs a curtain wall model according to the design drawings, and then arranges the construction of the curtain wall model. The method then assembles the curved aluminum plate curtain wall according to the construction arrangement, scans the curtain wall body, calculates the construction error, corrects the curved aluminum plate curtain wall monomers, and constructs an actual model. Finally, all the curved aluminum plate curtain wall monomers are gradually installed, and the constructed actual model is analyzed in real time to complete the prefabricated construction of the curved aluminum plate curtain wall. The method of the present invention can number and sort the blocks of each curtain wall model and assign features according to the curtain wall model, which can effectively facilitate subsequent orderly installation, avoid installation dislocation of the curved aluminum plate, ensure the reliability of installation, save installation time, and improve installation efficiency. At the same time, through the calculation of construction errors and the correction of the curved aluminum plate curtain wall monomers, the correlation between the curved aluminum plate curtain wall monomers can be made closer, the stability and firmness are higher, and the overlap error of the curved aluminum plate curtain wall monomers is controllable. In addition, the actual model is used to truly reflect the installation status of the curved aluminum plate curtain wall monomers, and after the curved aluminum plate curtain wall is completed, a real curved aluminum plate curtain wall model can be obtained, which is convenient for subsequent data storage and later maintenance.
