Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to an integrated assembly and installation method for steel plate wall core tube staggered trusses and cantilever trusses. Background Technology

[0002] Urban construction environments are complex and diverse, with large-span and cantilevered high-rise buildings emerging in large numbers. Truss structures have become an excellent building structure form that has emerged as the construction industry has continued to develop. However, how to assemble heavy trusses at high altitudes has become a challenge.

[0003] Traditional methods for assembling high-altitude truss structures include the following: First, the overall jacking method, hydraulic lifting method, and overall hoisting method. The disadvantages of these methods are that it is difficult to control the error and deformation, and when the weight of the structure is very large, the requirements for the load-bearing capacity of the lower part are very high. Second, the high-altitude sliding method. This method requires a long time to occupy vertical transportation machinery, and the sliding is difficult and the construction speed is slow. Third, the high-altitude assembly method. This method pays great attention to the installation sequence and is relatively dangerous. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provide an integrated assembly and installation method for steel plate wall core tube staggered trusses and cantilever trusses, solving the problem of high-altitude splicing and installation of large-span trusses.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0006] An integrated assembly and installation method for steel plate wall core tube staggered trusses and cantilever trusses, characterized in that: it includes standard section jigs, adjusting section jigs, connecting rods between jigs, transverse trusses, longitudinal trusses, longitudinal cantilever trusses, and other secondary structures;

[0007] Specifically, the steps include the following:

[0008] Step 1: First, based on the positioning of the upper column nodes of the structure, install the standard section jig and the adjusting section jig;

[0009] Step 2: Based on the installed core tube and standard section jig and adjusting section jig, install the connecting rod between the jigs. The connecting rod is arranged at the position of the middle longitudinal truss and at the vertical axis of the longitudinal cantilever truss to prevent displacement of the top of the jig.

[0010] Step 3: Based on the installed core tube and standard and adjusting section jigs, install the transverse trusses and longitudinal cantilever trusses to ensure that the first section of the truss has a stable anchoring point;

[0011] Step 4: Install the relevant longitudinal trusses based on the installed transverse trusses, so that the longitudinal trusses and the installed transverse trusses form a structure. Fix the newly installed trusses to the existing structure, so that the newly added components can quickly form a system with the existing structure.

[0012] Step 5: Repeat steps 3 and 4 to install the transverse trusses, longitudinal trusses, and longitudinal cantilever trusses alternately, ensuring that the standard section jig, adjusting section jig, transverse trusses, longitudinal trusses, and longitudinal cantilever trusses form a locally stable structural system as quickly as possible, until all trusses are installed and form a whole.

[0013] Step 6: Finally, insert and complete the truss installation by inserting the remaining secondary structures.

[0014] The beneficial effects of this invention are as follows: As can be seen from the above technical solution, this application provides an integrated assembly and installation method for steel plate wall core tube staggered trusses and cantilever trusses, including standard section jigs, adjusting section jigs, connecting rods between jigs, transverse trusses, longitudinal trusses, longitudinal cantilever trusses, and other secondary structures; this will greatly reduce the difficulty of installation and construction, and can greatly reduce the misalignment between component interfaces, which greatly promotes quality. In addition, the project involves a large number of components assembled at high altitudes, and the weight is large. Using this method can enable the components to form a structure in the shortest possible time, increasing the stability and safety of the structure. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0029] like Figure 12 As shown: An integrated assembly and installation method for steel plate wall core tube staggered trusses and cantilever trusses, characterized in that: it includes a standard section jig 1, an adjusting section jig 2, connecting rods between jigs 3, a transverse truss 4, a longitudinal truss 5, a longitudinal cantilever truss 6, and other secondary structures 7.

[0030] Standard section frame 1: The standard section frame includes a bottom transfer beam and standard frame sections. The bottom transfer beam is mainly used to transfer the load from the upper frame main section to the columns or beams of the lower concrete structure. The standard frame sections support the structural load.

[0031] Adjustment section 2: The main limbs and diagonal braces of the upper adjustment section 21 are all welded on-site from H-beams to fill the gap between the standard section of the adjustment section and the upper structure. The end H-beam support section needs to be 50mm higher than the predetermined elevation during installation to adjust the installation of the truss.

[0032] Transverse trusses, longitudinal trusses, longitudinal cantilever trusses, and other secondary structures are components of a truss structure. These structures have large spans, heavy weights, and complex nodes, requiring a well-defined installation sequence to ensure smooth installation. During installation, the force systems of the standard section jig, adjusting section jig, connecting rods between jigs, transverse trusses, longitudinal trusses, and longitudinal cantilever trusses continuously change.

[0033] During the assembly and installation of the standard section jig and transverse truss, the transverse truss and its nodes weigh an average of 30-50 tons, are approximately 12 meters long and 5 meters high, and have irregular node shapes, resulting in varying center of gravity positions at each node. During installation, this inevitably adds a bending moment to the ends of the jig, causing it to become top-heavy and thus displaced.

[0034] During the assembly and installation of standard section jigs, adjustment jigs, and longitudinal trusses, the nodes of the transverse trusses may be misaligned with those of the longitudinal trusses due to factors such as displacement at the ends of the jigs. This can result in excessively large weld seams at the joints or insufficient spacing between nodes, making it difficult to install, adjust, and weld the longitudinal trusses.

[0035] The connecting rods between the jigs fix the distance between them, ensuring that after the transverse truss is installed, the jigs and the transverse truss together form a stable whole, reducing the impact of displacement at the ends of the jigs.

[0036] The specific installation method for the integrated combination of steel plate wall core tube staggered trusses and cantilever trusses includes the following steps:

[0037] Step 1: First, based on the positioning of the upper column nodes of the structure, install the standard section jig and the adjusting section jig. The jig should be as follows: Figures 1 to 3 ;

[0038] Step 2: Based on the installed core tube 8 and the standard and adjusting section jigs, install the connecting rods between the jigs. The connecting rods are positioned at the intermediate longitudinal truss location and perpendicular to the longitudinal cantilever truss axis to prevent displacement at the top of the jig. Figure 4 ;

[0039] Step 3: Based on the installed core tube and standard and adjusting section jigs, install the transverse trusses and longitudinal cantilever trusses, ensuring the first truss section has a stable anchoring point to guarantee the safety of subsequent construction and the stability of the structure, and to reduce the negative impact of truss end displacement. Figure 5 ;

[0040] Step 4: Install the relevant longitudinal trusses based on the already installed transverse trusses, forming a structural unit with the installed transverse trusses. Secure the newly installed trusses to the existing structure, ensuring the new components quickly integrate with the existing system. This guarantees installation stability and minimizes the impact of subsequent installations on the existing trusses. Figure 6 ;

[0041] Step 5: Repeat steps 3 and 4, alternating the installation of transverse trusses, longitudinal trusses, and longitudinal cantilever trusses. This ensures that the standard section frame, adjusting section frame, transverse trusses, longitudinal trusses, and longitudinal cantilever trusses form a locally stable structural system as quickly as possible, until all trusses are installed and form a unified whole. Figures 7 to 10 .

[0042] Step 6: Finally, complete the truss installation by inserting and replacing the secondary structure, such as... Figure 11 ;

[0043] The process flow of this application is as follows: First, construct the support frame and install adjustment joints above the support frame to fine-tune the height of the support frame; then, construct the connecting rods between the support frames to fix the relative displacement between the support frames; then, construct the transverse trusses and longitudinal cantilever trusses, with the truss roots first fixed to the core tube; next, insert the longitudinal trusses between the transverse trusses to form a structure with the transverse trusses, longitudinal trusses, core tube, and support frame; finally, insert the secondary structures between the trusses to complete the installation of the truss layer.

[0044] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
