Description

Technical Field

[0001] The present invention relates to the technical field of concrete precast component processing, and particularly relates to a method, medium and system for reducing damage during the demoulding process of precast blocks. Background Art

[0002] With the rapid development of the modern construction industry, concrete precast components have been widely used in various construction projects due to their high efficiency, standardization and environmental protection characteristics. Especially for small concrete precast components, concrete precast molds can be used for production according to the required quantity during the construction process, which has the characteristics of flexible and convenient use.

[0003] In the demoulding process of using concrete precast molds to make small concrete precast components, in order to facilitate demoulding, generally, a knocking method is used to separate the concrete precast mold from the small concrete precast component. Since it is manually operated, during the knocking demoulding process, the knocking positions and sequences adopted by each person are different. For example, knocking in a certain area causes stress concentration, which leads to the formation of damage defects on the surface of the small concrete precast component during demoulding, thus affecting the aesthetics and even the performance of the small concrete precast component.

They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. In the accompanying drawings:

[0034] Figure 1 It is a flowchart of a method for reducing damage during the demoulding process of precast blocks disclosed in an embodiment of the present invention. Detailed implementation manners

[0035] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0036] In the prior art, generally, concrete precast molds are made of steel, such as using angle steel, I-beam, steel plate, etc. After injecting concrete into the concrete precast mold and waiting for it to solidify, an adhesion layer is formed at the interface between the concrete and the concrete precast mold during the solidification process. When demoulding after the concrete has finally set, it is necessary to destroy the microstructure of the adhesion layer to separate the concrete precast from the concrete precast mold, and generally, the method of knocking on the concrete precast mold is used.

[0037] Figure 1 The flowchart of the method for reducing damage during the demoulding process of precast blocks disclosed in an embodiment of the present invention is shown, including the following steps:

[0038] S1. Construct an analysis model of the concrete precast mold and the concrete precast.

[0039] S2. Use the above model for analysis to obtain the factors affecting the bonding ability of the concrete precast mold and the concrete precast respectively.

[0040] The purpose of constructing the analysis model is to obtain the factors affecting the adhesive force of the concrete precast mold and the factors affecting the adhesive force of the concrete precast.

[0041] In the above steps S1 to S2, the steps of constructing the analysis model of the concrete precast mold and the concrete precast and performing the analysis are as follows:

[0042] Construct models of the concrete precast mold and the concrete precast, and define the attribute parameters of the models according to their parameters respectively;

[0043] Simulate the adhesion layer and monitor it;

[0044] Adjust the parameters of the precast concrete mold or precast concrete component respectively. According to the set adhesion force fluctuation threshold, extract the parameter adjustment items exceeding the threshold and define them as factors.

[0045] Among them:

[0046] The above factors include the parameter adjustment items of the precast concrete mold. The parameter adjustment items of the precast concrete mold obtained by using the above analysis model are defined as adhesion-affected factors, and an adhesion-affected factor tree is formed.

[0047] Specifically, by adjusting the parameters of the precast concrete mold and through the monitoring of the simulated adhesive layer, when the adhesion force fluctuation of the simulated adhesive layer exceeds the adhesion force fluctuation threshold, the current parameter item is extracted.

[0048] The above factors include the parameter adjustment items of the precast concrete component. The parameter adjustment items of the precast concrete component obtained by using the above analysis model are defined as adhesion factors, and an adhesion factor tree is formed.

[0049] Specifically, by adjusting the parameters of the precast concrete component and through the monitoring of the simulated adhesive layer, when the adhesion force fluctuation of the simulated adhesive layer exceeds the adhesion force fluctuation threshold, the current parameter item is extracted.

[0050] S3. Dynamically adjust the above factors and synchronously import them into the simulation model for preparing precast concrete components with the precast mold to calculate the adhesion force parameters, forming an adhesion force parameter set.

[0051] The steps of dynamically adjusting the factors imported into the simulation model for preparing precast concrete components with the precast mold to calculate the adhesion force parameters are as follows:

[0052] Construct the models of the precast concrete mold and precast concrete component, and define the attribute parameters of the models according to their parameters respectively.

[0053] Simulate the adhesive layer and monitor it.

[0054] Adjust the adhesion-affected factors affecting the adhesion ability of the precast concrete mold and / or the adhesion factors affecting the adhesion ability of the precast concrete component.

[0055] Synchronously extract the adhesion force parameters obtained from the simulated adhesive layer to form an adhesion force parameter set.

[0056] In the first embodiment, during the above process of calculating the adhesion force parameters, adjust the adhesion-affected factors of the precast concrete mold and keep the adhesion factors of the precast concrete component unchanged. Respectively simulate them with the adhesion factor tree to obtain several groups of corresponding adhesion force parameters, which are defined as the first adhesion force parameter subset.

[0057] Exemplarily, the adjustable parameters affecting the adhesion force of the precast concrete mold include adhesion factors such as the roughness of the contact surface between the precast concrete mold and the precast concrete, and the type of release agent applied.

[0058] When adjusting the parameters of the precast concrete mold, the roughness of the contact surface between the precast concrete mold and the precast concrete is adjusted in a step-by-step decreasing or increasing manner.

[0059] When adjusting the parameters of the precast concrete mold, the method of sequentially selecting the release agent to be applied is adopted.

[0060] When the release agent cannot be used under special construction conditions, when calculating the adhesion force parameters, the release agent as an adhesion factor in the adhesion factor tree needs to be excluded.

[0061] In the second embodiment, during the above simulation process, the adhesion factors of the precast concrete are adjusted while keeping the adhesion factors of the precast concrete mold unchanged, and several groups of corresponding adhesion force parameters are obtained through simulation with the adhesion factor tree respectively, which are defined as the second subset of adhesion force parameters.

[0062] Exemplarily, the adjustable parameter adjustment items affecting the adhesion force between the precast concrete and the precast concrete mold include concrete strength, concrete component ratio, etc.

[0063] When adjusting the concrete strength and the concrete component ratio, the content of each component of the concrete is adjusted in a step-by-step decreasing or increasing manner.

[0064] In the third embodiment, during the above simulation process, the adhesion factors of the precast concrete mold and the adhesion factors of the precast concrete are adjusted, and several groups of corresponding adhesion force parameters are obtained through simulation between them after adjustment, which are defined as the third subset of adhesion force parameters.

[0065] S4. Set the performance threshold range of the precast concrete, filter the above adhesion force parameter set, and obtain the required parameters of the precast concrete mold and the precast concrete.

[0066] The steps of obtaining the required parameters of the precast concrete mold and the precast concrete include: after filtering according to the performance threshold range of the precast concrete, taking out the adhesion parameters within the threshold range, and then taking out the lowest value through numerical comparison, and outputting the corresponding parameters of the precast concrete mold and the precast concrete according to the lowest value.

[0067] S5. Use the parameters of the above precast concrete mold and precast concrete to construct a demolding simulation analysis model to obtain the load application parameters.

[0068] The process of performing simulation to obtain the load application parameters includes:

[0069] Identify the strong adhesion points and weak adhesion points between the precast concrete mold and the precast concrete component;

[0070] Analyze the area occupied by the strong adhesion points, divide the area into several blocks, and set virtual strong load application points in each divided block;

[0071] Analyze the area occupied by the weak adhesion points, divide the area into several blocks, and set virtual weak load application points in each divided block;

[0072] Use the above virtual strong load application points and virtual weak load application points to simulate the virtual load application sequence, and monitor the damage data on the surface of the precast concrete component;

[0073] When the damage data on the surface of the precast concrete component obtained at the virtual load application points obtained from the simulation and the corresponding virtual load application sequence is the slightest or there is no damage, output the load application points and the load application sequence.

[0074] The above slightest or no damage is obtained by comparing the sizes of the damage data of each group of simulations. The meaning of slightest is that the damage data is the smallest, and the meaning of no damage is that there is no damage data.

[0075] S6. Output the parameters of the precast concrete mold and the precast concrete component, as well as the load application parameters, and fabricate and demold the precast concrete component according to the obtained parameters and load application parameters.

[0076] The load application parameters include the load application points and the load application sequence. Among them, mark the load application points and the load application sequence at the corresponding positions of the precast concrete mold, such as setting marks on the surface of the precast concrete mold.

[0077] After setting the threshold according to the parameters and performance of the required small precast concrete components, the present invention can automatically generate the corresponding parameters of the precast concrete mold, the precast concrete component, and the load application parameters. After fabricating the precast concrete mold according to the parameters and preparing the concrete according to the parameters and pouring the concrete into the precast concrete mold, when performing the demolding process, applying the load on the precast concrete mold according to the load application parameters can achieve demolding, and at the same time reduce the damage occurring during the demolding process.
