Description

Technical Field

[0001] The invention belongs to the technical field of steel structure buildings, and in particular relates to a construction method for dry-hanging ceramic brick curtain walls of steel structure buildings. Background Art

[0002] Steel structure buildings play a very important role in modern architecture. Compared with traditional brick-concrete or reinforced concrete structures, steel structures have the advantages of light weight, good earthquake resistance, and short construction period. They are widely used in high-rise buildings, factories, stadiums and other fields. In order to further improve the overall performance of steel structure buildings, dry-hanging ceramic brick curtain wall technology has been gradually developed in recent years. Dry-hanging ceramic brick curtain wall is a new type of building exterior wall structure. It uses a steel structure skeleton as a load-bearing system and uses clay bricks as exterior decorative materials on this basis. Compared with traditional heavy brick-concrete exterior walls, this structural form has the advantages of light weight, good thermal insulation performance, and easy maintenance. At the same time, dry-hanging ceramic brick curtain wall can also enrich the shape of the building facade and enhance the aesthetic effect of the building.

[0003] However, there are also some problems with the existing dry-hanging ceramic brick curtain wall construction technology. First, due to the flexibility of the steel structure itself, it is easy to produce large deformation, which requires the rigidity of the steel structure to be strengthened during the design. Secondly, the connection method between the clay bricks and the steel structure directly affects the overall bearing capacity and service life of the curtain wall. Furthermore, how to ensure the quality control of each process during the construction process is also a major challenge. Therefore, there is an urgent need for a new method for the construction of dry-hanging ceramic brick curtain walls for steel structure buildings that can effectively solve the above problems.

[0159] The comprehensive objective function is:

[0160] F=0.16f1+0.14f2+0.12f3+0.15f4+0.13f5+0.14f6+0.16f7;

[0161] Among them, w i is the weight coefficient of each objective function.

[0162] The constraints include:

[0163] 1. Reinforcement rib and surface steel plate thickness constraint: 2≤d i ≤10, (i=1, 2, 3);

[0164] 2. Strengthen rib spacing constraint: 600≤s i ≤900, (i=1, 2, 3, 4, 5);

[0165] 3. Surface steel plate width constraint: 220≤b i ≤280, (i=1, 2, 3);

[0168] 6. Deformation constraint: Δ max ≤50 / 500;

[0169] 7. Safety factor constraint: K s ≥1.5;

[0170] By solving the above multi-objective optimization model, the optimal reinforcement rib arrangement scheme and surface steel plate arrangement scheme are obtained. The details are as follows:

[0171] Reinforcement rib arrangement scheme:

[0172] The steel material used is Q345B, with thicknesses of d1=6mm, d2=8mm, d3=8mm, and the spacings are s1=700mm, s2=750mm, s3=800mm, s4=850mm, s5=900mm respectively.

[0173] Surface steel plate layout plan:

[0174] The steel material used is Q235B, with widths b1=240mm, b2=260mm, b3=260m, and thicknesses d4=6mm.

[0175] After determining the optimal component layout plan, the specific construction process begins.

[0176] First, the surface of the steel structure components was precisely cleaned. An ultrasonic detector was used to scan the entire surface, and a small amount of rust and mortar residue was found. A high-pressure jet device (jet pressure of 18MPa) was used to remove the rust, and then mechanical grinding was used to remove the mortar residue (grinding depth not exceeding 0.3mm). Finally, the surface flatness was measured using a laser flatness detector, and the results showed that the flatness error was controlled within 1.5mm, which met the requirements.

[0177] Secondly, according to the optimization plan, the reinforcement ribs and surface steel plates are welded on the surface of the steel structure. First, the surface of the component is positioned, and then the reinforcement ribs are welded and fixed using double-sided fillet welds (weld size 6mm). The weld quality inspection pass rate reaches 98%. Then, the surface steel plate is welded to the reinforcement ribs and steel components using double-sided fillet welds (weld size 8mm).

[0178] Secondly, channel steel is welded on the surface steel plate with a spacing of 600mm, and steel keels are arranged between the channel steels. M12 high-strength bolts (spacing no more than 400mm) are used to connect the steel keels to the channel steels, and welding reinforcement is used at key nodes (weld size 6mm).

[0179] Then, the fixed angle steel is welded on the steel keel (weld spacing 300mm), and the connecting angle steel is connected to it through M8 bolts, and the verticality error is tested to be within 1 degree. Finally, the connecting angle steel is welded to the steel keel with a continuous weld (weld thickness not less than 5mm).

[0180] After the skeleton structure is completed, the full-length steel plate is laid. First, the installation reference line is determined by measurement and setting out, and then the steel plate is laid along the reference line, with the edge straightness controlled within 2mm. Then, bolt connection holes (hole diameter 10mm) are opened on the steel plate at a spacing of 300mm, and the steel plate is fixed to the connecting angle steel with M8 high-strength bolts (torque controlled at 80N·m).

[0181] Next is the standard layer laying process of clay bricks. First, draw a 240mm×115mm positioning grid on the full-length steel plate, and use a CNC drill to open a 12mm diameter through hole according to the grid. Use a 1:3 ratio of cement mortar to lay the first layer of clay bricks on the steel plate with a masonry thickness of 10mm. The theodolite detection found that the verticality error was controlled within 2mm. Then lay the clay bricks layer by layer to ensure that the coaxial deviation between the internal holes and the steel plate openings is less than 1.5mm.

[0182] The last step is to pour cement mortar into the holes inside the clay bricks. Round steel bars are used as positioning steel bars and are welded and fixed to the openings of the steel plates. Then cement mortar with a strength grade not less than M20 is prepared and pressure grouting (grouting pressure 0.6MPa) is used to fill the holes inside the clay bricks until they are completely full.

[0183] We took comprehensive quality inspection measures throughout the construction process. In key processes such as surface treatment, welding, and bolt connection, ultrasonic flaw detection, infrared thermal imaging, and digital measurement were used for real-time monitoring and sampling inspection. For quality problems found, such as defects in welds, loose bolt connections, and incomplete mortar pouring, repairs were carried out in a timely manner. Finally, through comprehensive evaluation, the quality acceptance rate of the curtain wall project reached more than 98%, meeting the use requirements.

[0184] In general, the new method for dry-hanging ceramic brick curtain wall construction of steel structure buildings proposed by the present invention has been well verified in practice in this project. Through the application of a series of measures such as multi-objective optimization design, precise surface treatment, innovative connection structure and reliable masonry technology, the problems existing in the existing construction technology are effectively solved, which not only ensures the overall performance of the curtain wall structure, but also improves the level of construction quality control, providing experience for reference for the development of similar projects in the future.

[0203] Step 107: Substitute the optimal strengthening stiffener rib arrangement scheme into the finite element analysis model for stress verification to obtain the final surface steel plate arrangement scheme.

[0204] First, step S10 is to establish and solve a multi-objective optimization model for a steel structure building dry-hanging ceramic brick curtain wall to obtain an optimal strengthening rib arrangement scheme and an optimal surface steel plate arrangement scheme. The specific implementation method is as follows:

[0205] Step 101, establish an objective function matrix of steel structure building dry hanging ceramic brick curtain wall. The matrix includes 7 objective functions, namely material cost minimization function f1, structure weight minimization function f2, construction period minimization function f3, structure deformation minimization function f4, wind pressure resistance optimization function f5, earthquake resistance optimization function f6 and thermal performance optimization function f7. These objective functions comprehensively consider various factors such as materials, structural performance and construction, aiming to seek the optimal design scheme of steel structure dry hanging ceramic brick curtain wall in terms of cost, weight, construction period, deformation, wind pressure resistance, earthquake resistance and thermal performance.

[0206] Step 102, construct a constraint matrix. The matrix includes the constraint 2≤d i ≤10, surface steel plate thickness constraint 2≤d i ≤10, Strengthen the rigid rib spacing constraint 500≤s i ≤1000, surface steel plate width constraint 200≤b i ≤300, Stress constraint of steel structure components σ max ≤0.85[σ], clay brick weight load constraint G max ≤0.7[G], curtain wall overall deformation constraint Δ max ≤H / 500 and connection node safety factor constraint K s ≥1.5. These constraints ensure that the steel structure dry-hanging ceramic brick curtain wall can meet the design requirements in all aspects of performance indicators.

[0207] Step 103: Establish an objective function weight distribution model. Use the analytic hierarchy process to calculate the weight coefficient w of each objective function in the objective function matrix. i , to reflect the importance of each objective function in the comprehensive objective function. This weight allocation method can better reflect the preferences and actual needs of decision makers.

[0208] Step 104, preliminarily solving the objective function based on the particle swarm optimization algorithm. The particle swarm optimization algorithm is a group intelligence optimization algorithm that simulates the behavior principle of bird flocks foraging to find the global optimal solution. The algorithm has the advantages of fast convergence speed and easy implementation, and is suitable for solving complex multi-objective optimization problems. Through the preliminary solution of the algorithm, an initial solution set can be obtained.

[0209] Step 105, use the non-dominated sorting genetic algorithm to screen the initial solution set for the Pareto optimal solution. The non-dominated sorting genetic algorithm is a classic multi-objective optimization algorithm that can effectively find the Pareto optimal solution set with conflicts between objective functions. The algorithm obtains the optimal solution set that satisfies each objective function by non-dominated sorting and congestion calculation.

[0210] Step 106, using a fuzzy decision method to select the optimal strengthening stiffener arrangement scheme from the Pareto optimal solution. The fuzzy decision method uses fuzzy mathematical theory to deal with uncertain factors, and by constructing a fuzzy comprehensive evaluation model and combining the decision maker's preference information, the final optimal strengthening stiffener arrangement scheme is selected from the Pareto solution.

[0211] Step 107, the optimal strengthening rib arrangement scheme is substituted into the finite element analysis model for stress verification, thereby obtaining the final surface steel plate arrangement scheme. Finite element analysis can more accurately simulate the stress distribution of the steel structure dry-hanging ceramic tile curtain wall under various loads, ensuring that the surface steel plate arrangement scheme meets the structural safety requirements.

[0260] Specifically, the principle of the present invention is: the core of the new method for construction of dry-hanging ceramic brick curtain wall of steel structure building of the present invention is to establish a multi-objective optimization model and determine the best layout of the curtain wall structure by means of system optimization design:

[0261] First, the objective function matrix includes seven objective functions, including minimizing material cost, minimizing structural weight, minimizing construction period, minimizing structural deformation, optimizing wind pressure resistance, optimizing seismic performance, and optimizing thermal performance. These objective functions fully consider the performance requirements of steel structure dry-hanging ceramic brick curtain wall in all aspects;

On this basis, the particle swarm optimization algorithm is used to solve the initial solution set to obtain a set of Pareto optimal solutions. Finally, the fuzzy decision method is used to select the final optimal reinforcement rib arrangement scheme from the Pareto solution set, and it is substituted into the finite element analysis model for further verification to obtain the optimal surface steel plate arrangement scheme;

At the same time, a variety of constraints are introduced into the optimization model to ensure the feasibility and reliability of the optimization design scheme in practical application;
