Description

Technical Field

[0001] The present invention relates to the technical field of curtain wall structure construction, and particularly to an assembly construction method for a curved aluminum plate curtain wall. Background Art

[0002] With the development of Chinese society and the progress of technology, more and more personalized buildings have gradually come into people's sight. The facades of these personalized building projects are mostly completed by special-shaped building curtain walls. In order to highlight the individuality of the buildings, architects have incorporated elements such as elliptical surfaces, broken line surfaces, parabolic surfaces, hyperbolic surfaces or free-form surfaces into the outer enclosing structures of the personalized buildings, making the overall lines of these personalized buildings appear more beautiful and dynamic, revealing a fashionable atmosphere and the spirit of the times that people pursue individuality in today's society. A curtain wall is the exterior wall of a building, which is composed of various strong, lightweight and beautiful structural frame materials and panels, making the building into a beautiful, multi-functional and safe exterior wall, and generally serving as a decorative wall in modern large high-rise buildings. The curved curtain wall not only poses higher requirements for the curtain wall, but also because the construction errors of the main structure of the building are often relatively large.

[0003] In the patent document with the application number "CN202311361674.X" and the name "An assembly installation construction method for a hyperbolic aluminum plate curtain wall", it is recorded that: "It includes the following specific steps: S1. According to the bending arc radius of the curtain wall outer surface shown in the hyperbolic aluminum plate curtain wall drawing, establish a curtain wall skin model, and on the basis of the skin model, draw the skin of the completed surface of the keel and the intersection points of the keels according to the node drawing and the keel grid; S2. On the basis of S1, use BIM technology to generate the center line of the keel surface and the keel model, and extract the bending arc radii of the keels in different parts; S3; S4; S5; S6. Use single-curved treatment of thick aluminum single plates to manufacture diamond-shaped aluminum single plates. This construction method ensures that the completed surface of the keel meets the design effect after the keel is installed by determining the accurate bending arc radius of the bent keel, twists the butt joints of the keels to ensure the unity of the completed surface of the keel joints, and changes the conventional single-keel installation method into integral hoisting by welding ground plates, with high precision, shortened construction period and reduced cost". Although the assembly installation construction method for the hyperbolic aluminum plate curtain wall provided by this patent document has advantages such as a 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.

[0005] Based on this, the present invention provides an assembled construction method for a curved aluminum plate curtain wall to solve the above-mentioned technical problems. Summary of the invention

[0033] Figure 1 It is a flowchart of the prefabricated construction method of the curved aluminum plate curtain wall of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0034] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment: As Figure 1 shown, this embodiment provides an assembly construction method for a curved aluminum plate curtain wall, including the following steps:

[0036] S1. Obtain the design drawings, construct a curtain wall model according to the design drawings, and then perform construction sequencing on the curtain wall model.

[0037] Among them, the process of construction sequencing is:

[0038] Extract the curtain wall model blocks from the curtain wall model;

[0039] Then number and sequence and endow features to each curtain wall model block;

[0040] Among them, the numbering and sequencing is carried out according to the construction sequence of the design drawings, and the feature endowment includes endowing the associated information of adjacent curtain wall model blocks and the positioning information of the corresponding curtain wall model blocks.

[0041] In this embodiment, it should be noted that the curtain wall model can be constructed by including but not limited to building the curtain wall model based on BIM technology, etc. As an implementation method, the curtain wall model block is a single curved aluminum plate curtain wall, that is, a single curved aluminum plate. In this embodiment, by numbering, sequencing and endowing features to each curved aluminum plate, it can effectively facilitate the subsequent orderly installation, avoid the installation dislocation of the curved aluminum plates, ensure the reliability of the installation and save the installation time, improve the installation efficiency. Among them, the features include but are not limited to the position identification code of the curved aluminum plate and the adjacent curved aluminum plate, such as 0000 + 0001 + 01, where 0000 is the installation code of this curved aluminum plate, 0001 is the installation code of the adjacent curved aluminum plate, and 01 is the position code, such as being on the left side of 0000.

[0042] S2. Carry out the assembly construction of the curved aluminum plate curtain wall according to the construction sequencing respectively, scan the curtain wall main body, calculate the construction error, and correct the single curved aluminum plate curtain wall and construct the actual model.

[0043] Among them, the process of carrying out the assembly construction of the curved aluminum plate curtain wall according to the construction sequencing is:

[0044] Mark the corresponding construction sequencing information on the processed single curved aluminum plate curtain wall;

[0045] Install the single curved aluminum panel curtain wall step by step according to the construction sequencing information.

[0046] In this embodiment, it should be noted that the sequencing information is marked on the single curved aluminum panel curtain wall for subsequent sequenced installation.

[0047] In addition, before the assembly construction of the curved aluminum panel curtain wall according to the construction sequence, it also includes:

[0048] Set out the lines, and after the line setting is completed, install the fixtures according to the positioning lines for the keel installation.

[0049] After the installation of the fixtures and the bases is completed, start installing the keels.

[0050] After the keels are installed, install the adapter pieces for the single curved aluminum panel curtain wall. The adapter pieces are firmly connected to the keels by bolts and can slide along the keels for movement adjustment.

[0051] After the keels are installed firmly and inspected and accepted, carefully check the installation positioning of the adapter pieces. After ensuring accurate positioning, start installing the single curved aluminum panel curtain wall.

[0052] In this embodiment, it should be noted that the line setting can be carried out by including but not limited to the polar coordinate method (for irregular shapes, measure and set out the lines based on the plan view and the curtain wall model, and then go to the construction site for actual measurement and line setting according to the obtained data). In addition, when installing the keels, according to the construction sequence, determine the construction reference keel, and then carry out the keel construction step by step from top to bottom according to the grid size requirements.

[0053] In addition, when installing the single curved aluminum panel curtain wall, first install the single curved aluminum panel curtain wall in sequence according to the sequencing information. At the same time, during the installation process, check the given features to ensure the correct relationship between adjacent single curved aluminum panel curtain walls and avoid installation errors. As an implementation method, after the installation of the first single curved aluminum panel curtain wall is completed, install the second single curved aluminum panel curtain wall, and at the same time check the feature information on the first single curved aluminum panel curtain wall and the second single curved aluminum panel curtain wall to ensure the correct installation positions of the first single curved aluminum panel curtain wall and the second single curved aluminum panel curtain wall.

[0054] Among them, the process of correcting the single curved aluminum panel curtain wall is as follows:

[0055] Obtain the calculated construction error and compare it with the preset construction error threshold.

[0056] If it is within the error threshold, no adjustment is made to the corrected single curved aluminum panel curtain wall.

[0057] If it is not within the threshold, reinstall the corrected single curved aluminum panel curtain wall.

[0058] 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 plate curtain wall units to construct the actual model.

[0059] In this embodiment, it should be noted that through the calculation of construction errors and the correction of the curved aluminum plate curtain wall units, the correlation between the curved aluminum plate curtain wall units can be relatively tight, with high stability and firmness, and the lap error of the curved aluminum plate curtain wall units can be controlled. As an implementation method, the preset construction error threshold can be set within 0.2 mm. That is, when the construction error of the positive-curved aluminum plate curtain wall unit is less than 0.2 mm, the positive-curved aluminum plate curtain wall unit is adjusted. If the construction error of the positive-curved aluminum plate curtain wall unit is greater than or equal to 0.2 mm, then the positive-curved aluminum plate curtain wall unit needs to be reinstalled and adjusted, and the construction error calculation and correction are carried out again until the construction error of the positive-curved aluminum plate curtain wall unit is less than 0.2 mm.

[0060] In addition, after correcting the curved aluminum plate curtain wall units, the adjacent positive-curved aluminum plate curtain wall units can be fixed for the second time. The methods of the second fixation include, but are not limited to, welding, and the means of injecting glue can also be used simultaneously to increase the stability and correlation of the positive-curved aluminum plate curtain wall units.

[0061] S3. Gradually install all the curved aluminum plate curtain wall units and analyze the constructed actual model in real time to complete the assembly construction of the curved aluminum plate curtain wall.

[0062] Among them, analyzing the content of the constructed actual model in real time means 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.

[0063] In addition, it also includes installing decorative strips and cleaning up after finishing the installation of all the curved aluminum plate curtain wall units.

[0064] In this embodiment, it should be noted that by gradually installing all the curved aluminum plate curtain wall units and analyzing the constructed actual model in real time, it can effectively ensure that the installation of the curved aluminum plate curtain wall units meets the design technical requirements, use the actual model to truly reflect the installation situation of the curved aluminum plate curtain wall units, and after completing the curved aluminum plate curtain wall, a real curved aluminum plate curtain wall model can be obtained, which is convenient for subsequent data storage and later maintenance, etc.

[0065] The prefabricated construction method of the curved aluminum plate curtain wall provided by the present invention includes obtaining the design drawings, constructing a curtain wall model according to the design drawings, then sequencing the construction of the curtain wall model, and then respectively carrying out the assembly construction of the curved aluminum plate curtain wall according to the construction sequence, scanning the main body of the curtain wall, calculating the construction error, and correcting the single curved aluminum plate curtain wall and constructing the actual model. Finally, all the single curved aluminum plate curtain walls 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 sequence each block of the curtain wall model and endow it with features according to the curtain wall model, which can effectively facilitate the subsequent orderly installation, avoid the misalignment of the installation of the curved aluminum plates, ensure the reliability of the installation, save the installation time, improve the installation efficiency.
