Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent construction, and in particular to an intelligent arrangement system and method of template support frames for a building construction project. Background Art

[0002] In traditional housing construction projects, the design and layout of formwork support frames usually rely on manual calculations and layout designs by experienced engineers. Although this method can ensure the safety and stability of the support frame to a certain extent, it also has many disadvantages, which restricts the efficiency of the project and the effective use of resources.

[0003] Traditional design methods are inefficient. Since manual design requires a lot of time and manpower, engineers need to calculate the stress conditions, material requirements, and layout rationality of each support point one by one. This not only prolongs the design cycle, but also increases labor costs, especially in large-scale construction projects. In addition, traditional design is often based on experience and intuition, lacking a systematic optimization process, which can easily lead to excessive or insufficient use of materials and waste of resources. In addition, the layout of the support frame is not reasonable enough, which may cause the construction team to face complex operations during assembly and disassembly, increasing the difficulty and time cost of construction. At the same time, the shortcomings of traditional methods in dynamic response analysis also significantly affect the safety of the structure. Due to the lack of real-time analysis tools, the actual stress and displacement of the support frame during construction are often difficult to accurately grasp, increasing the risk of structural failure. Especially when facing external loads (such as wind, earthquake, etc.), the dynamic response of the support frame may not be fully considered, resulting in potential safety hazards. There is also a lack of comprehensive simulation and evaluation of the support frame installation process, which may cause the construction team to face unforeseen problems in actual operation, increasing construction risks.

[0004] To this end, technical personnel in this field have proposed an intelligent arrangement system and method for formwork support frames for housing construction projects, aiming to optimize the design and layout of formwork support frames, improve construction efficiency and safety, reduce material waste, and achieve efficient use of resources by integrating intelligent algorithms, real-time dynamic analysis, and three-dimensional simulation technology.

[0081] K·u=F

[0082] Among them, u is the node displacement vector, which is used to solve the equation group to obtain the displacement of each node and the structural analysis result;

[0083] After the mechanical analysis is completed, the force analysis is carried out to analyze the reverse force of each support point. According to the displacement u and stiffness of each node, the reaction force R of each point is calculated, which is expressed as:

[0084] R i =K i ·u i

[0092] The genetic algorithm is used to optimize the position and configuration of the support frame, and the steps are as follows: a. randomly generate several support frame layout schemes, each scheme represents an individual;

[0093] b. Calculate the fitness value of each individual, expressed as:

[0094] Minimize f(x)=C(x)+α·ω(x)

[0095] Among them, C(x) is the total cost of the support frame, ω(x) is the weight of the support frame, which is the weight of the support system, and α is the weight coefficient, which is used to balance the cost and stability, and impose constraints, including the bearing capacity conditions of each support point: Minimum spacing between support points: Maximum number of support frames: N s ≤N max ;

[0099] f. Finally, the arrangement scheme with the highest fitness is selected as the final support frame configuration, and the intelligent arrangement result is generated, and the type, quantity, location, and corresponding materials and specifications of the support frame are output. Through the above steps and formulas, the automatic selection and optimization process of the intelligent arrangement algorithm can be realized. This process combines structural mechanics, cost analysis, and intelligent algorithms to provide efficient support solutions for construction projects.

[0100] The intelligent layout algorithm module can effectively and automatically analyze the stress of the building structure based on the imported drawings and parameters, and determine the location and number of support points. This process not only improves the efficiency of engineering design, but also enhances the safety and reliability of construction.

[0101] The three-dimensional simulation module is used to obtain the type, position, specification and quantity information of the support frame according to the intelligent arrangement results. The three-dimensional structure of the support frame is represented by the following formula to represent the basic geometry of the support frame:

[0103] Where D is the spatial area of ​​the support frame and its connecting parts, and the volume V of this area is calculated;

[0104] Construct the connection relationship between the support frame and the template, and coordinate the support model with the template, which can be expressed as:

[0105] P′=A·P+b

[0106] Among them, P′ is the transformed coordinate, A is the transformation matrix, P is the support point coordinate vector, and b is the translation vector.

[0107] The 3D simulation module is also used to simulate the installation process of the support frame. For each installation step of the support frame, a state sequence is set, which is expressed as: S = {s1, s2, ..., s n}, where s i represents the state of the i-th step;

[0108] Set the transformation formula for each step to perform dynamic transformation, expressed as: S i =S i-1 +ΔS, where ΔS is the position change during one installation process;

[0110] The entire construction process is simulated step by step, and the force and displacement of the support frame during the construction process are calculated through dynamic simulation. The stability evaluation is expressed as:

[0111] K.u f =F f

[0112] Where K is the global stiffness matrix, u f is the real-time displacement during construction, F f is the load applied during the construction phase; its safety assessment is expressed as:

[0114] Among them, σ f Indicates the actual stress of the material during the construction process, σ y It indicates the yield strength of the material so that at each stage of construction, the stress does not exceed the yield strength of the material.

[0115] The safety calculation module performs static analysis on the three-dimensional model of the support frame to evaluate the stress of the support frame under static load and ensure its structural safety. By establishing a stress model, the load is classified into static load and live load, and then the load is combined and expressed as: F total =γ L ·F live +γ D ·W total , where F total represents the load vector acting on the node, γ L , γ D is the corresponding load factor, F live is the live load, W total is a static load;

[0116] Establish the equilibrium equation to analyze the response of the support frame. The equilibrium equation is expressed as: K·u=F total , where K is the stiffness matrix, u is the displacement vector, and F total is the load vector acting on the node; stress analysis is performed using the stress-strain relationship, expressed as: σ = E·ε, where σ is stress, E is the elastic modulus of the material, and ε is strain; and the reaction force is calculated for each support point, expressed as: R = K·u, where R is the reaction force.

[0117] The safety calculation module also performs dynamic analysis on the three-dimensional model of the support frame to evaluate the response of the support frame under dynamic loads and ensure its stability and safety under external forces. The dynamic model is established by considering factors such as the mass, stiffness and damping of the structure: Where M is the mass matrix, C is the damping matrix, and F dynamic is the load vector under dynamic conditions;

[0118] The dynamic response is solved by numerical methods, and the natural frequency domain and modal vibration shape of the structure are calculated, which can be expressed as: The dynamic response is solved by direct integration method, which is expressed as: Evaluate the dynamic response, displacement and acceleration response, record the displacement, velocity and acceleration at the set time t, expressed as: u(t) = Asin(ωt+φ), where u(t) is the displacement at time t, A is the amplitude of the displacement, ω is the angular frequency, and φ is the initial phase; calculate the maximum response, and obtain the maximum displacement and stress value to evaluate safety, expressed as: u max ,σ max =max(u(t),σ(t)), where u max represents the maximum displacement recorded in the dynamic analysis, σ max It represents the maximum stress value recorded under dynamic loading conditions, and max(u(t),σ(t)) represents the maximum displacement u(t) and maximum stress σ(t) in the dynamic response process. The analysis results are compared with the tensile strength and yield strength of the material to ensure the safety of the structure.

[0119] Through the combination of static analysis and dynamic analysis, the safety verification module can comprehensively evaluate the stability and safety of the support frame to ensure its reliability in actual construction.
