[0044] According to the BIM-based reinforced concrete structure construction management method of an embodiment of the present invention, a BIM model can be established according to the design parameters and construction plan of the building, and a comprehensive analysis of the resource usage status and building quality status during the construction process can be conducted based on the planned construction information, reference position coordinates and standard concrete strength obtained from the BIM model. Furthermore, a management plan for the building is determined according to the resource usage status and building quality status, thereby improving the effectiveness of the construction management of the reinforced concrete structure project.

[0045] According to an embodiment of the present invention, in step S101, a BIM model is established according to the design parameters and construction plan of the building.

[0046] For example, determine the design parameters of the building (such as geometric dimensions, floor layout, structural form and size, etc.) based on the building's design drawings, obtain the building's construction plan, organize the collected design parameters, and select appropriate BIM modeling software based on the organized design parameters and construction plan to establish a BIM model. The BIM model can accurately count the engineering volume of the construction project and display the structure of the construction project in three dimensions.

[0047] According to an embodiment of the present invention, in step S102, planned construction information is obtained according to the BIM model, wherein the planned construction information includes: planned construction manpower consumption, planned construction material consumption and planned construction progress.

[0048] For example, the BIM model can integrate all relevant information of a construction project, including data from various stages such as design, construction, operation and maintenance. Through the BIM model, the planned construction manpower consumption, planned construction material consumption and planned construction progress of the construction project can be obtained.

[0049] According to an embodiment of the present invention, in step S103, actual construction manpower consumption, actual construction material consumption and actual construction progress are obtained.

[0050] For example, the actual construction manpower consumption, actual construction material consumption, and actual construction progress of a construction project during the construction cycle can be obtained based on the construction log.

[0051] According to one embodiment of the present invention, in step S104, a resource optimization management plan for the i+1th construction cycle is determined based on the planned construction manpower consumption, the planned construction material consumption, the planned construction progress, the actual construction manpower consumption, the actual construction material consumption and the actual construction progress.

[0052] According to one embodiment of the present invention, step S104 includes:

[0053] Determining a first determination coefficient according to the planned construction manpower consumption, the planned construction material consumption, the planned construction progress, the actual construction manpower consumption, the actual construction material consumption and the actual construction progress;

[0054] According to the first determination coefficient, a resource optimization management plan for the (i+1)th construction cycle is determined.

[0055] For example, based on the planned construction manpower consumption, planned construction material consumption, planned construction progress, actual construction manpower consumption, actual construction material consumption and actual construction progress, the resource consumption status of the construction project is evaluated to determine the first determination coefficient; based on the first determination coefficient, a plan for optimizing resource management in the next construction cycle is determined.

[0056] According to an embodiment of the present invention, determining a first determination coefficient according to the planned construction manpower consumption, the planned construction material consumption, the planned construction progress, the actual construction manpower consumption, the actual construction material consumption and the actual construction progress includes: determining the first determination coefficient according to formula (1): , (1),

[0057] Among them, if is a conditional function, is the planned construction progress at the end of the i-th construction period, is the actual construction progress at the end of the i-th construction cycle, is the actual construction manpower consumption at the end of the i-th construction cycle, is the actual construction material consumption at the end of the i-th construction cycle, is the planned construction manpower consumption at the end of the i-th construction cycle, is the planned construction material consumption at the end of the i-th construction period, is the preset ratio threshold.

[0058] According to one embodiment of the present invention, is the ratio of the actual construction progress to the planned construction progress at the end of the i-th construction cycle, indicating the degree of completion of the construction progress. is the ratio of the actual construction material consumption to the planned construction material consumption at the end of the i-th construction cycle, indicating the degree of construction material consumption. It is the ratio of the actual construction manpower consumption to the planned construction manpower consumption at the end of the i-th construction cycle, indicating the degree of consumption of construction human resources.

[0059] According to one embodiment of the present invention, in formula (1), the conditional function The value of includes the following two cases, when it satisfies When the condition is met, the relative difference between the completion degree of the construction progress at the end of the i-th construction cycle and the consumption degree of construction materials is less than the preset ratio threshold, indicating that the completion degree of the construction progress at the end of the i-th construction cycle is more matched with the consumption degree of construction materials, and no abnormal use of construction materials occurs. The value of the condition function is 0. When it is not met When the condition is met, it means that the completion degree of the construction progress at the end of the i-th construction cycle does not match the consumption degree of construction materials. Abnormal use of construction materials may occur, and it is necessary to optimize the management of construction material resources. The value of the conditional function is 1.

[0060] According to one embodiment of the present invention, in formula (1), the conditional function The value of includes the following two cases, when it satisfies When the condition is met, the relative difference between the degree of completion of the construction progress at the end of the i-th construction period and the degree of consumption of construction human resources is less than the preset ratio threshold, indicating that the degree of completion of the construction progress at the end of the i-th construction period and the degree of consumption of construction human resources are more matched, and the value of the condition function is 0. When the condition is met, it means that the degree of completion of the construction progress at the end of the i-th construction cycle does not match the degree of consumption of construction human resources. Abnormal use of human resources may occur, and the use of human resources needs to be optimized and managed.

[0061] In this way, the first determination coefficient can be determined based on the planned construction manpower consumption, planned construction material consumption, planned construction progress, actual construction manpower consumption, actual construction material consumption and actual construction progress. During the calculation process, it can be determined whether it is necessary to optimize the management of construction resources based on the degree of matching between material consumption and construction progress and the degree of matching between manpower consumption and construction progress, thereby improving the comprehensiveness and accuracy of the first determination coefficient.

[0062] According to an embodiment of the present invention, determining a resource optimization management scheme for the (i+1)th construction period according to the first determination coefficient includes:

[0063] If the first determination coefficient is 0, there is no need to perform resource optimization management in the (i+1)th construction cycle;

[0064] If the first determination coefficient is 1, optimizing the use of construction materials in the (i+1)th construction cycle;

[0065] If the first determination coefficient is 2, the use of human resources is optimized in the (i+1)th construction cycle;

[0066] If the first determination coefficient is 3, the use of construction materials and human resources is optimally managed in the (i+1)th construction cycle.

[0067] For example, if the first determination coefficient is 0, it means that no abnormal situation has occurred in the use of construction materials and human resources, and there is no need for resource optimization management in the i+1th construction cycle; if the first determination coefficient is 1, it means that abnormal situation in the use of construction materials has occurred in the i-th construction cycle, and it is necessary to strengthen the management of the use of construction materials in the i+1th construction cycle; if the first determination coefficient is 2, it means that abnormal situation in the use of human resources has occurred in the i-th construction cycle, and it is necessary to strengthen the management of the use of human resources in the i+1th construction cycle; if the first determination coefficient is 3, it means that abnormal situation in the use of human resources and construction materials has occurred in the i-th construction cycle, and it is necessary to strengthen the management of the use of human resources and construction materials in the i+1th construction cycle.

[0068] According to one embodiment of the present invention, in step S105, actual sampling points are set at preset positions of the building, and virtual sampling points are set at corresponding positions of the BIM model.

[0069] For example, actual sampling points are set at preset positions such as key structures and vertices of the building, and virtual sampling points are set at corresponding positions of the BIM model according to the mapping relationship between the BIM model and the building.

[0070] According to an embodiment of the present invention, in step S106, the concrete strength at the actual sampling point and the actual position coordinates of the actual sampling point in the building coordinate system are obtained, wherein the building coordinate system is a coordinate system established based on a preset origin within the range of the building.

[0071] For example, a building coordinate system is established with the centroid of the bottom floor of the building as the preset origin, a reference distance measuring sensor is set at a preset position in the building coordinate system, and a distance measuring sensor is set at the actual sampling point. The actual position coordinates of the actual sampling point in the building coordinate system are obtained according to the distance measuring sensor, and the concrete strength at the actual sampling point is detected by the ultrasonic rebound comprehensive method.

[0072] According to an embodiment of the present invention, in step S107, the reference position coordinates of the virtual sampling point in the building coordinate system are determined according to the mapping relationship between the building and the BIM model, and the standard concrete strength at the virtual sampling point is obtained according to the BIM model.

[0073] For example, the BIM building model is a virtual three-dimensional model generated according to the design parameters of the building. BIM can completely map the actual information of the building. According to the mapping relationship between the building and the BIM model, the position coordinates of the virtual sampling point in the building coordinate system, that is, the reference position coordinates, are determined. According to the BIM model, the concrete strength that should be achieved at the virtual sampling point, that is, the standard concrete strength, is determined.

[0074] According to one embodiment of the present invention, in step S108, a building maintenance management plan for the (i+1)th construction period is determined based on the concrete strength, the actual position coordinates, the reference position coordinates and the standard concrete strength.

[0075] According to one embodiment of the present invention, step S108 includes:

[0076] Determine the actual vertex position coordinates at the vertex of the building according to the actual position coordinates;

[0077] Determine the actual building frame coordinate vector according to the actual vertex position coordinates at any two different vertices;

[0078] Determine the reference vertex position coordinates at the vertex of the building in the BIM model according to the reference position coordinates;

[0079] Determine the reference building frame coordinate vector according to the reference vertex position coordinates at any two different vertices in the BIM model;

[0080] Determine the first screening area and the second screening area of ​​the building through the BIM model, wherein the first screening area is an area where the steel bars are densely distributed in the building, and the second screening area is an area where the steel bars are sparsely distributed in the building;

[0081] Setting a first screening point at a preset position of the first screening area, and determining a first ultrasonic characteristic value at the first screening point;

[0082] Setting a second screening point at a preset position of the second screening area, and determining a reference ultrasonic characteristic value at the second screening point;

[0083] Determine a building quality abnormality coefficient according to the first ultrasonic eigenvalue, the reference ultrasonic eigenvalue, the actual building frame coordinate vector, the reference building frame coordinate vector, the concrete strength, the actual position coordinates, the reference position coordinates and the standard concrete strength;

[0084] According to the building quality abnormality coefficient, a building maintenance management plan for the (i+1)th construction cycle is determined.

[0085] For example, the actual sampling points include the vertices of the building. Among the actual position coordinates of multiple actual sampling points, the actual vertex position coordinates of the vertices of the building are determined; the actual building frame coordinate vector is combined according to the actual vertex position coordinates of any two different vertices; the reference vertex position coordinates of the vertices of the building in the BIM model are determined, and the reference building frame coordinate vector is combined according to the reference vertex position coordinates of any two different vertices; the first screening area with dense distribution of steel bars and the second screening area with sparse distribution of steel bars in the building are screened out through the BIM model. Since the steel bars in the first screening area are densely distributed, the concrete pouring difficulty in the first screening area is higher, and the uneven concrete pouring phenomenon is more likely to occur; the first screening point is set at the load-bearing structure (such as load-bearing columns and load-bearing beams) in the first screening area , evenly set the second screening points in the second screening area, and detect the first screening points and the second screening points by ultrasonic detection method, determine the first ultrasonic characteristic value at the first screening point and the reference ultrasonic characteristic value (ultrasonic characteristic value under the condition of uniform concrete pouring) at the second screening point, the ultrasonic characteristic value refers to the sound speed or amplitude of the ultrasonic wave, and the uniformity of the sound speed and amplitude can reflect the uniformity of concrete pouring to a certain extent; according to the first ultrasonic characteristic value, the reference ultrasonic characteristic value, the actual building frame coordinate vector, the reference building frame coordinate vector, the concrete strength, the actual position coordinates, the reference position coordinates and the standard concrete strength, evaluate the abnormal condition of the building quality and determine the building quality abnormality coefficient; according to the building quality abnormality coefficient, determine the building maintenance management plan for the next construction cycle.

[0086] According to one embodiment of the present invention, the building quality abnormality coefficient is determined according to the first ultrasonic characteristic value, the reference ultrasonic characteristic value, the actual building frame coordinate vector, the reference building frame coordinate vector, the concrete strength, the actual position coordinate, the reference position coordinate and the standard concrete strength, including: determining the building quality abnormality coefficient at the end time of the i-th construction cycle according to formula (2): , ,

[0087] in, , , , , , , and is the preset weight, max is the maximum value function, if is the conditional function, is the actual position coordinate of the kth actual sampling point at the end of the i-th construction cycle, is the reference position coordinate of the kth virtual sampling point at the end of the i-th construction cycle, is the preset modulus difference threshold, is the mth actual building frame coordinate vector, for The transposed vector of is the mth reference building frame coordinate vector, is the concrete strength at the kth actual sampling point, is the standard concrete strength at the kth virtual sampling point, is the first ultrasonic characteristic value of the rth first screening point of the eth load-bearing structure in the first screening area at the end time of the ith construction cycle, is the reference ultrasonic eigenvalue, R is the number of the first screening points of a single load-bearing structure, r≤R, K is the number of actual sampling points, k≤K, M is the number of actual building frame coordinate vectors, m≤M, E is the number of load-bearing structures in the first screening area, e≤E, and e, E, r, R, k, K, m and M are all positive integers.

[0088] According to one embodiment of the present invention, It is the ratio of the modulus of the difference between the actual position coordinates of the kth actual sampling point at the end of the i-th construction period and the reference position coordinates of the kth virtual sampling point at the end of the i-th construction period to the preset modulus difference threshold. The larger the ratio, the greater the deviation between the position of the kth actual sampling point and the reference position in the design scheme, and the more abnormal the quality of the building. In order to obtain the maximum deviation between the K actual sampling points and the reference position in the calculation scheme, the above-mentioned maximum value processing can be used to determine the maximum deviation condition among multiple actual sampling points, and the building quality abnormality coefficient is determined based on this, so that the building quality abnormality coefficient can reflect the quality of the building. is the cosine similarity between the mth actual building frame coordinate vector and the mth reference building frame coordinate vector. The smaller the cosine similarity, the greater the deformation of the building frame corresponding to the mth actual building frame coordinate vector. The average value is calculated based on the number of actual building frame coordinate vectors to represent the overall deformation of the building frame. The larger the average value, the more serious the overall deformation of the building frame and the more abnormal the building quality. To determine the abnormal quality condition of the building's steel structure based on the position deviation condition at the sampling point and the overall deformation condition of the building frame.

[0089] According to one embodiment of the present invention, is the relative difference between the concrete strength at the kth actual sampling point and the standard concrete strength. The larger the ratio is, the smaller the concrete strength at the kth actual sampling point is, and the more abnormal the concrete strength quality is. The maximum value of the relative difference between the concrete strength at K actual sampling points and the standard concrete strength is taken. The above maximum value processing can be used to determine the maximum strength quality abnormality at any actual sampling point. Based on this, the building quality abnormality coefficient can be determined, which can make the building quality abnormality coefficient reflect the worst condition of concrete strength, which is convenient for determining the quality of concrete strength of the building. In formula (2), the conditional function The value of includes the following two cases, when it satisfies When the condition is met, it means that the concrete strength at the kth actual sampling point does not meet the standard, and the value of the condition function is 1. When the condition is met, it means that the concrete strength at the kth actual sampling point meets the standard, and the value of the condition function is 0. It is the ratio of the number of actual sampling points that do not meet the concrete strength standards to all actual sampling points. The larger the ratio, the worse the overall concrete strength quality of the building and the greater the building quality abnormality coefficient. is the relative difference between the first ultrasonic characteristic value and the reference ultrasonic characteristic value of the rth first screening point of the eth load-bearing structure in the first screening area at the end of the i-th construction cycle. The larger the ratio, the more serious the uneven degree of concrete pouring at the rth first screening point, and the easier it is to produce gaps such as bubbles at the rth first screening point. When the uneven degree of pouring at the first screening point is higher, the preset weight corresponding to the first screening point is The larger the value of It means taking the maximum value of the sum of the products of the concrete pouring abnormal conditions and the corresponding weights at the R first screening points. For example, when the first screening point at the e-th load-bearing structure is The value is 0.8, the value at the second screening point is 0.6, and the value at the third screening point is 0.7. The preset weights are , and , ,but The value of , which is greater than the weighted sum of other concrete pouring abnormal conditions and weights. For example, Therefore, the maximum weighted sum value can be selected, indicating that when there are more bubbles in the concrete of the same load-bearing structure, the impact on the load-bearing structure will be more serious as the number of bubbles increases, and the maximum value of the severity can be obtained to describe the overall abnormal condition of the load-bearing structure, where the preset weight The change is in the form of an exponential function, indicating that as the uneven degree of concrete pouring at the first screening point in the load-bearing structure increases, the impact on the load-bearing structure increases rapidly, and its matching preset weight increases in an exponential form, and not at a uniform rate. The above method of using the distribution weight value to find the maximum value can be used to solve the most serious situation of uneven concrete pouring. It is the average value of the uneven concrete pouring condition of each load-bearing structure, indicating the overall uneven concrete pouring condition of the screening area. To determine the abnormal concrete quality condition of the building based on the maximum strength quality abnormality at the actual sampling point, the overall concrete strength quality abnormality and the overall concrete pouring abnormality.

[0090] According to one embodiment of the present invention, It means that the building quality abnormality coefficient is determined based on the abnormal quality conditions of the building's steel structure and concrete.

[0091] In this way, the building quality abnormality coefficient can be determined according to the first ultrasonic eigenvalue, the reference ultrasonic eigenvalue, the actual building frame coordinate vector, the reference building frame coordinate vector, the concrete strength, the actual position coordinates, the reference position coordinates and the standard concrete strength. During the calculation process, the steel structure quality abnormality can be analyzed according to the position deviation at the sampling point and the overall deformation of the building frame. The concrete quality abnormality of the building can be evaluated according to the maximum strength quality abnormality, the overall concrete strength quality abnormality and the overall concrete pouring abnormality at any actual sampling point. Furthermore, the abnormality of the building quality is evaluated according to the two aspects of the steel structure quality abnormality and the concrete quality abnormality, and the building quality abnormality coefficient is determined, thereby improving the comprehensiveness and accuracy of the building quality abnormality coefficient.

[0092] According to one embodiment of the present invention, determining a building maintenance management plan for the (i+1)th construction period according to the building quality abnormality coefficient includes:

[0093] Obtain the historical actual position coordinates and historical concrete strength of the historical actual sampling point at the end of the i-1th construction cycle and the historical reference position coordinates and standard concrete strength of the historical virtual sampling point at the end of the i-1th construction cycle;

[0094] Determine the building quality abnormality coefficient at the end of the (i-1)th construction cycle according to the historical actual position coordinates, the historical concrete strength, the historical reference position coordinates and the standard concrete strength;

[0095] The building maintenance management plan for the i+1th construction cycle is determined based on the building quality abnormality coefficient at the end of the i-th construction cycle and the building quality abnormality coefficient at the end of the i-1th construction cycle.

[0096] For example, the actual position coordinates and concrete strength of the actual sampling point at the end of the i-1th construction cycle in the historical database are obtained; the building quality abnormality coefficient at the end of the i-1th construction cycle is determined based on the historical actual position coordinates, historical concrete strength, historical reference position coordinates and standard concrete strength. The calculation method of the building quality abnormality coefficient at the end of the i-1th construction cycle is similar to formula (2) and will not be repeated here; based on the building quality abnormality coefficients of the i-th construction cycle and the i-1th construction cycle, the building maintenance management plan for the i+1th construction cycle is determined.

[0097] According to one embodiment of the present invention, a building maintenance management plan for the i+1th construction cycle is determined based on the building quality abnormality coefficient at the end of the i-th construction cycle and the building quality abnormality coefficient at the end of the i-1th construction cycle, including:

[0098] If the building quality abnormality coefficient at the end of the i-th construction period is greater than a set building quality abnormality coefficient threshold, determining to perform maintenance management on the building;

[0099] If the building quality abnormality coefficient at the end of the i-th construction cycle is greater than the building quality abnormality coefficient at the end of the i-1-th construction cycle, it is determined that maintenance management is to be performed on the building.

[0100] For example, if the building quality abnormality coefficient at the end of the i-th construction cycle is greater than the set building quality abnormality coefficient threshold, it means that the building constructed in the i-th construction cycle has quality problems, and the construction personnel need to be notified to perform maintenance and management on key locations such as the building's load-bearing structure; during the construction process, the building part under construction will exert pressure on the completed building part, causing the completed building part to deform. If the building quality abnormality coefficient at the end of the i-th construction cycle is greater than the building quality abnormality coefficient at the end of the i-1-th construction cycle, it means that the building under construction in the current i-th construction cycle has an abnormal impact on the completed building part, and the construction personnel need to be notified to perform maintenance and management on key locations such as the load-bearing structure of the completed building part.

[0101] According to an embodiment of the present invention, in step S109, a management planning report for the (i+1)th construction period is determined based on the resource optimization management plan and the building maintenance management plan.

[0102] For example, the resource optimization management plan and building maintenance management plan for the i+1th construction cycle are sorted and summarized to determine the management planning report for the i+1th construction cycle.

[0103] According to the BIM-based reinforced concrete structure construction management method of the embodiment of the present invention, a BIM model can be established according to the design parameters and construction plan of the building, and the resource usage status and building quality status in the construction process can be comprehensively analyzed based on the planned construction information, reference position coordinates and standard concrete strength obtained by the BIM model. Further, the management plan of the building is determined according to the resource usage status and building quality status, thereby improving the effectiveness of the construction management of reinforced concrete structure engineering. When determining the first determination coefficient, the first determination coefficient can be determined according to the planned construction manpower consumption, planned construction material consumption, planned construction progress, actual construction manpower consumption, actual construction material consumption and actual construction progress. In the calculation process, it can be determined whether it is necessary to optimize the management of construction resources according to the matching degree of material consumption and construction progress and the matching degree of manpower consumption and construction progress, thereby improving the comprehensiveness and accuracy of the first determination coefficient. When determining the building quality abnormality coefficient, the building quality abnormality coefficient can be determined according to the first ultrasonic eigenvalue, the reference ultrasonic eigenvalue, the actual building frame coordinate vector, the reference building frame coordinate vector, the concrete strength, the actual position coordinates, the reference position coordinates and the standard concrete strength. In the calculation process, the steel structure quality abnormality can be analyzed according to the position deviation condition at the sampling point and the overall deformation condition of the building frame. The concrete quality abnormality of the building can be evaluated according to the maximum strength quality abnormality condition, the overall concrete strength quality abnormality condition and the overall concrete pouring abnormality condition at any actual sampling point. Furthermore, the abnormal condition of the building quality is evaluated according to the two aspects of the steel structure quality abnormality condition and the concrete quality abnormality condition, and the building quality abnormality coefficient is determined, thereby improving the comprehensiveness and accuracy of the building quality abnormality coefficient.
