It should be noted that, a plurality of gravity monitoring positions are selected from all the gravity monitoring positions, a plurality of stress monitoring positions are selected from all the stress monitoring positions, and the plurality of gravity monitoring positions and the plurality of stress monitoring positions are used as a plurality of actual monitoring positions.
In another embodiment, in order to better obtain the stress monitoring rod position in the second modeling model, however, since the built high-formwork model is subjected to different areas of the second modeling model when being subjected to the pressure of the concrete, the areas with high applied pressure need to be selected to be more than a few positions to serve as the stress monitoring rod position. Obtaining a plurality of stress monitoring rods according to a second modeling model, referring to fig. 2, including the following steps:
s510, dividing the second modeling model into a plurality of different stress areas.
Since there are several ways to divide the second modeling model into different force-bearing areas, in order to enable the divided areas to more closely conform to the actual force, the second modeling model is divided into a plurality of different force-bearing areas, referring to fig. 3, comprising the steps of:
s511, acquiring a first deformation according to the first modeling model.
S512, obtaining a second deformation according to the second modeling model.
And S513, acquiring a pressure influence value according to the first deformation quantity and the second deformation quantity.
S514, dividing the second modeling model into a plurality of stress areas according to the pressure influence values, wherein each stress area corresponds to a plurality of pressure influence values.
The first deformation is characterized by the deformation of the high formwork due to the gravity of the high formwork, the second deformation is characterized by the deformation of the high formwork due to the gravity of the concrete, and the pressure influence value is characterized by the compression degree of the second modeling model in a preset range. The force-receiving area is characterized as a distinct area into which the entire second modeling model is divided.
The grid regions corresponding to the first deformation amount and the second deformation amount in the second modeling model are divided according to the performance of the software, so that the accuracy of the software is high, and the number of divided grid regions of the second modeling model is higher. In this embodiment, model mesh division is performed by ANSYS, and mesh areas are divided into 10000 copies. In addition, the dividing modes of the areas corresponding to the first deformation amount and the second deformation amount and the stress area are different, and the stress area comprises a plurality of grid areas.
Specifically, the pressure influence value is a value set according to the difference between the first deformation amount and the second deformation amount, in this embodiment, the pressure influence value is manually set according to the difference between the first deformation amount and the second deformation amount, and the pressure influence value is specifically a value within 1-100, and the larger the value is, the larger the difference between the first deformation amount and the second deformation amount of the grid area is.
For example, the mesh region a, the mesh region B, and the mesh region C have the first deformation amounts of 0, 0.1, and 0.2, the second deformation amounts of 40, 60, and 79, and thus the corresponding differences of the first deformation amounts and the second deformation amounts are 40, 59.9, and 78.8, and thus the pressure influence values corresponding to the mesh region a, the mesh region B, and the mesh region C are set to 30, 55, and 70.
It should be noted that the difference between the corresponding pressure influence values in each stress area is not greater than a preset fixed value. The preset fixed value is a preset value, the preset fixed value can be set according to the obtained actual monitoring rod position, if the actual monitoring rod position is centralized in comparison, the preset fixed value can be set smaller, and if the actual monitoring rod position is decentralized in comparison, the preset fixed value can be set larger. The obtained actual monitoring rod position can be comprehensive, and the actual stress condition of the high formwork can be monitored more accurately.
For example, the pressure influence values corresponding to the grid area a, the grid area B and the grid area C are 30, 31 and 70 respectively, the preset fixed value is 2, the grid area a and the grid area B are adjacent, the grid area a and the grid area B can be regarded as the same stress area through calculation, and the grid area C is regarded as another stress area.
S520, screening out a plurality of temporary stress rod positions in each stress area.
The temporary stress rod positions are characterized as positions of rods to be detected which are screened out in each stress area. It should be noted here that, since each stress area includes a plurality of grid areas.
Selecting a plurality of temporary stress rod positions according to each stress area, comprising the following steps:
s521, a plurality of temporary stress rod positions are obtained according to the pressure value ratio corresponding to each stress area, and the ratio of the number of the temporary stress rod positions obtained by the stress area to the number of the stress monitoring rods is the pressure value ratio corresponding to the stress area.
The pressure numerical ratio is characterized by a plurality of pressure influence values corresponding to each stress area. The specific calculation mode of the pressure numerical ratio is to calculate a plurality of pressure influence values included in the stress area to obtain a corresponding average ratio, and then the ratio of the average ratio to the maximum pressure influence value is used as the pressure numerical ratio.
In another embodiment, after dividing the second modeling model into a plurality of force-receiving areas according to the pressure influence value, the method further comprises the steps of:
s521-1, calculating a stress average value corresponding to each stress area according to a plurality of pressure influence values corresponding to the stress area.
S521-2, and taking the ratio of the average ratio to the maximum pressure influence value as the pressure value ratio.
The pressure numerical ratio is characterized as the compression degree of the corresponding stress area, and the sum of the pressure numerical ratios corresponding to all the stress areas divided by the second modeling model is 1.
For example, the pressure influence values corresponding to the grid area a, the grid area B and the grid area C are 30, 31 and 70 respectively, the preset fixed value is 2, the grid area a and the grid area B are adjacent, the grid area a and the grid area B can be regarded as the same stress area a through calculation, the grid area C is regarded as another stress area B, the average ratio corresponding to the stress area a is 30.5, and the average ratio corresponding to the stress area B is 70, therefore, the pressure value ratio a corresponding to the stress area a is 0.305, and the pressure value ratio B corresponding to the stress area B is 0.7.
Therefore, assuming that 100 stress monitoring bars need to be obtained in total from the stress area a and the stress area b, by calculation, the stress area a needs to obtain 30 stress monitoring bars, and the stress area b needs to obtain 70 stress monitoring bars.
And S530, adding the temporary stress rod positions corresponding to different stress areas as stress monitoring rod positions.
In another embodiment, a plurality of actual monitoring positions are obtained according to a plurality of gravity monitoring positions and a stress monitoring position, referring to fig. 4, the method comprises the following steps:
s610, obtaining modeling pressure corresponding to the second modeling model, and judging whether the modeling pressure is larger than preset modeling pressure.
S620, if the modeling pressure is greater than the preset modeling pressure, acquiring a plurality of actual monitoring rods by using a preset first influence factor, wherein the first influence factor is smaller than 1, and the ratio of the number of the gravity monitoring rods to the number of the stress monitoring rods in the actual monitoring rods is the first influence factor.
S630, if the modeling pressure is not greater than the preset modeling pressure, acquiring a plurality of actual monitoring rods by using a preset second influence factor, wherein the second influence factor is greater than 1, and the ratio of the number of the gravity monitoring rods to the number of the stress monitoring rods in the actual monitoring rods is the second influence factor.
The modeling pressure is characterized by the gravity of the concrete applied by the second modeling model, and the preset modeling pressure is characterized by the pressure of the lowest concrete deformed by the second modeling model. The first influence factor and the second influence factor are the ratio of the number of the gravity monitoring rods to the number of the stress monitoring rods in the actual monitoring rod position, and the first influence factor is smaller than 1, and the second influence factor is larger than 1.
For example, the data of the modeling pressure is divided into different levels according to 1-10, the first influence factors corresponding to the different levels of the data of the modeling pressure are respectively set according to 0.1-1, the second influence factors corresponding to the different levels of the data of the modeling pressure are respectively set in sequence according to 1-1.9, specifically, the data of the modeling pressure is 1, the first influence factor at the moment is 0.1, the second influence factors are 1, and the first influence factors corresponding to the data of the modeling pressure of the rest different levels are analogized in sequence.
If the estimated modeling pressure is 80, the preset modeling pressure is 60, the first influence factor is 0.8, and the estimated modeling pressure 80 is greater than the preset modeling pressure by 60, so that the ratio of the number of gravity monitoring rods in the actual monitoring rods to the number of stress monitoring rods is 0.8, and the number of stress monitoring rods is greater than the number of gravity monitoring rods.
If the estimated modeling pressure 30 is 80, the second influence factor is 1.3, so the ratio of the number of the gravity monitoring bars to the number of the stress monitoring bars in the actual monitoring point is 1.3, and the number of the stress monitoring bars is smaller than the number of the gravity monitoring bars.
After the actual monitoring positions are obtained, the actual high formwork model needs to be monitored, and in another embodiment, after the actual monitoring positions are obtained according to the gravity monitoring positions and the stress monitoring positions, the method further comprises the following steps:
s710, the actual monitoring rod positions acquire the deformation corresponding to each actual monitoring rod, and the deformation corresponding to each actual monitoring rod is compared with the preset deformation according to the deformation corresponding to each actual monitoring rod.
S720, if the deformation corresponding to one of the actual monitoring rods is larger than the preset deformation, warning an operator that the high formwork support needs to be trimmed.
Wherein, deformation quantity characterization is the deformation degree of actual monitoring pole position. The preset deformation amount is characterized as the lowest measurement of deformation of the high formwork support.
The method is characterized in that if the deformation corresponding to one of the actual monitoring rods is not larger than the preset deformation, an operator is reminded of safety.
The implementation principle of the method for monitoring the deformation of the high formwork in the embodiment of the application is as follows: firstly, building a first modeling model and a second modeling model corresponding to high formwork data to be monitored and casting concrete data; then a plurality of gravity monitoring rod positions are obtained according to a first modeling model, a plurality of stress monitoring rod positions are obtained according to a second modeling model, wherein the second modeling model is divided into a plurality of different stress areas, each stress area corresponds to a different pressure numerical value ratio, different numbers of temporary stress rod positions are obtained in each stress area according to the pressure numerical value ratio, and the temporary stress rod positions of each stress area are added as stress monitoring rod positions; then, comparing the modeling pressure corresponding to the second modeling model with preset modeling pressure, if the modeling pressure is larger than the preset modeling pressure, the number of the stress monitoring rods is larger than that of the gravity monitoring rods, and if the modeling pressure is not larger than the preset modeling pressure, the number of the stress monitoring rods is smaller than that of the gravity monitoring rods; and finally, taking the obtained stress monitoring rod position and the gravity monitoring rod position as actual monitoring rod positions.
