Description

Technical Field

[0001] The present invention relates to the technical field of construction project information collection, storage and sharing, and in particular to a public information collection, storage and sharing platform for building construction projects. Background Art

[0002] With the increasing quality requirements of construction projects and the increasing competition in the construction industry, project management needs to be more and more refined. At the same time, project management involves many participants, and there are also many types of project materials and information. According to traditional paper documents and email communication, it is impossible to understand the status of project construction in a timely manner. Therefore, a public information collection, storage, and sharing platform for construction projects came into being.

[0003] As competition in the construction industry intensifies, the construction quality of construction projects becomes increasingly important, and ensuring the construction quality of projects is the foundation for an enterprise.

[0004] However, when the traditional public information collection, storage, and sharing platform for construction projects is in operation, it is unable to identify and judge the quality status of construction projects in all aspects, and it is even more unable to send the project quality status to many participants in a timely manner, resulting in frequent rework of construction projects and quality accidents, which increases the construction costs of enterprises. Therefore, how to identify the quality status of construction projects and send the project quality status to many participants in a timely manner is a technical problem that needs to be solved.

[0005] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0006] In order to solve the technical problems raised by the above background technology, the present invention is proposed. The embodiment of the present invention provides a public information collection, storage and sharing platform for building construction projects.

[0007] The purpose of the present invention can be achieved through the following technical solutions: a public information collection, storage and sharing platform for construction projects, including a data acquisition module, a steel module, an earthwork module, a concrete module and a processing and early warning module.

[0009] The steel module is used to analyze the steel element performance and steel bar status of the steel element information and joint information to obtain the steel grade value of the construction project;

[0010] The earthwork module is used to analyze the earthwork filling and excavation status of the construction project earthwork information to obtain the soil quality grade value of the construction project;

[0011] The concrete module is used to analyze the concrete pouring status of the concrete information to obtain the concrete quality grade value of the construction project;

[0012] The processing and early warning module receives the steel grade value, the soil grade value and the concrete grade value of the construction project, judges and analyzes the construction quality of the construction project based on the value, compares it with the set comparison interval, and issues corresponding early warning and processing.

[0013] Furthermore, the steel grade value analysis steps of the construction project are as follows:

[0014] Obtain the number of joints in the construction project where the compression steel bars are directly greater than 28 mm and the tension steel bars are directly greater than 25 mm, and mark them as the compression bias binding number and the tension bias binding number respectively, and sum them up to get the binding anomaly value. Compare the lap length of the steel bar lap joint with 300 mm, and count the proportion of construction projects exceeding 300 mm, mark it as the lap length compliance rate, obtain the joint percentage of each part, and perform average processing to get the joint anomaly value;

After comparison with the set reference plane, the distance deviations from each point on the weld surface to the reference plane are counted, and the weld surface deviation of the weld joint is obtained by summing them up; the vertical distance from the bottom of each bite edge of the weld joint to the surface of the parent material is measured, and the average value is marked as the average bite edge depth. The starting and ending points of each bite edge of the joint are counted to obtain the length of each bite edge, and the total length of the bite edge is obtained by summing them up. The average bite depth and the total bite length are summed to obtain the bite value of the weld joint; the ray penetrates the weld of the weld joint, and the internal image of the weld is obtained on the digital detector. The image is gray-scaled and compared with the set threshold. When it is less than the set value, it is determined to be a pore, and the number of pores in the weld joint is counted to obtain the weld excess height yg of the weld joint. The weld surface deflection, the bite value of the weld joint and the number of pores in the weld joint are marked as fp, jb and qk respectively, and normalized with the weld excess height yg of the weld joint.

When the displacement change exceeds the set displacement change threshold and the contact force decreases by more than the set decrease percentage threshold, the point is judged as a broken tooth, and the fluctuation frequency and amplitude of the contact force signal are obtained. When the fluctuation frequency is lower than the set fluctuation frequency threshold and the amplitude is lower than the set amplitude threshold, the point is judged as a bald tooth, and the sleeve steel wire is Starting from the starting end of the screwing, the head is divided into three equal parts, namely the first part, the second part and the third part, and the weighting coefficients c1, c2 and c3 are set respectively, among which c1>c2>c3, and the weight C is set as the position marked as the sleeve. The number of broken teeth and bald teeth in each part of the sleeve is counted, and the number of broken teeth and bald teeth in each position are multiplied by the set weight C, and the sum is obtained to obtain the sleeve tooth sink value of the mechanical joint. The sleeve crack value of the mechanical joint and the sleeve tooth sink value of the mechanical joint are weighted and calculated, and multiplied by the corresponding weight factor coefficient to obtain the sleeve crack value of the mechanical joint. The sleeve crack value of the mechanical joint is compared with the set threshold value, and the values ​​below the threshold range, within the threshold range and above the threshold range are counted, and the sleeve crack value Jt is obtained by analysis and calculation.

[0020] Furthermore, the steps for analyzing the property grade value of the steel material and the steel bar machine grade value are as follows:

The phosphorus, sulfur and nitrogen content of the steel are summed to obtain the reduced value of the mechanical properties of the steel. The nickel, chromium and molybdenum content of the steel are summed to obtain the improved value of the mechanical properties of the steel. The improved value of the mechanical properties of the steel, the reduced value of the mechanical properties and the silicon content of the steel are marked as jj, jt and gh respectively, and normalized according to the set formula The property grade value Gx of the steel is obtained, where a1, a2, a3, a4 and a5 are all set weight factor coefficients;
