Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a method for constructing, operating and maintaining a continuous beam by utilizing data display functions of a strain gauge and a metal detector.
Background
The continuous beam is an important component in a frame structure, the traditional design idea is that the section size of the continuous beam is determined by the span, then the load statistics calculation is carried out to calculate the internal force for reinforcement calculation, and finally the lapping and anchoring of the reinforcing steel bars are carried out according to the plain drawing set. The traditional construction method comprises the steps of firstly erecting a template according to a drawing, binding reinforcing steel bars, hoisting the reinforcing steel bars and pouring concrete. The traditional identification and detection method is to detect the strength of concrete by a resiliometer and detect the distance between reinforcing steel bars and the thickness of a reinforcing steel bar protective layer by manual scanning. The traditional design, construction, detection, later operation and maintenance and the like have the following defects and shortcomings. In the aspect of design, general designers can increase the load statistic value for conservation, and consider that the bearing capacity of the member is adjusted, so that S < < R, but the material waste is caused, and the engineering cost is increased. In the aspect of construction, the problems of template size deviation, wrong steel bar binding and lapping, non-compact concrete pouring and the like can occur due to manual reasons, so that the construction quality is poor, the construction period is delayed, construction materials are wasted, the construction cost is improved, and the like. In the aspect of identification and detection, a certain amount of cost for business and business is generated due to the complexity of engineering projects, in addition, errors can occur in detection results due to accidental factors in the detection, and the serious waste of funds can be caused if the construction quality does not reach the standard after the detection.
In the aspect of later operation and maintenance, because the concrete structure is the overrun that can't effectively avoid the crack of band gap work, if can't know in time that the crack overrun in the design service life, meet the strong wind or earthquake effect in addition and will bring huge economic loss. In combination with the above, the traditional thinking has the defects of poor construction quality, unclear component crack development, man-machine waste and the like. Based on the defects, the construction, operation and maintenance of the continuous beam can be avoided by utilizing the data display function of the strain gauge and the metal detector.
Disclosure of Invention
The invention aims to solve the problems of poor construction quality, unclear component crack development, man-machine waste and the like of the conventional continuous beam, and further provides a method for performing continuous beam construction, operation and maintenance by utilizing data display functions of a strain gauge and a metal detector.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a continuous beam with the data display function of strain gauges and metal detectors comprises a multi-span continuous beam, a plurality of metal induction sheets and a plurality of strain gauges. And placing a certain number of metal induction sheets in the bound reinforcement cage, and placing a certain number of strain gauges during concrete pouring. And connecting the metal induction sheet and the strain gauge on the electronic display screen. The space, the protective layer thickness and the lap joint length of the steel bar can be monitored in real time through the metal induction sheet in the construction process, and the development condition of the stress and the strain of the member can be monitored in real time through the strain gauge. If construction errors occur in the construction process, the problems of crack overrun and the like can be corrected in time, so that the situation of poor construction quality is avoided. During detection, the construction actual situation and the entering and exiting of the design drawing can be judged directly through image data in the electronic display screen. In the operation and maintenance stage, the stress-strain development condition in the beam is monitored in real time through the strain gauge, the post-processing is directly carried out according to the width of the crack, the reliability of the member is improved, the property of the crack is judged through image display, and the defects of the member in the use stage are overcome
Compared with the prior art, the invention has the following beneficial effects:
1) in the design stage, because the adjustment of designers is guaranteed to be far less than R, building materials are increased, the construction cost is improved, and the stress and deformation conditions of the component can be monitored in real time after the data display function of the strain gauge and the metal detector is utilized. The design may not be too conservative thereby reducing material costs.
2) In the construction stage, the problems of template size deviation, wrong steel bar binding and lapping, non-compact concrete pouring and the like can be caused due to manual errors, so that the construction quality is poor, the construction period is delayed, construction materials are wasted, the construction cost is improved, and the like. After the data display function of the strain gauge and the metal detector is utilized, the real-time monitoring can be realized through data image analysis, the construction quality is strictly controlled and is consistent with the design drawing as much as possible, and the error can be corrected in time when the error occurs. Therefore, the construction quality can be greatly improved, the rework condition is effectively avoided, and the construction method is greatly beneficial to reducing the construction cost of engineering projects.
3) In the detection stage, a certain amount of current cost is generated due to the complexity of engineering projects, in addition, errors can occur in the detection result due to accidental factors in the detection, and the serious waste of funds can be caused if the construction quality does not reach the standard after the detection. After the data display function of the strain gauge and the metal detector is utilized, a detector can directly acquire specific information of the component, such as the steel bar spacing, the steel bar protective layer thickness and the like according to the data image. Therefore, a large amount of manual detection cost is saved, and the detection result is more real and effective.
4) And in the later operation and maintenance stage, because the concrete structure is the overrun that can not effectively avoid cracks in the crack-carrying work, if the overrun of the cracks can not be known in time in the designed service life, huge economic loss can be brought by the action of strong wind or earthquake. After the data display function of the strain gauge and the metal detector is utilized, whether the crack is out of limit or not can be analyzed according to the image data displayed electronically, and therefore the crack can be remedied in time; the nature of the fracture can also be qualitatively judged according to the development trend of the fracture so as to take the medicine for the case. After the technology is applied, the component can be monitored in real time, the cost of later-period operation and maintenance is reduced, and economic property loss caused by improper maintenance is effectively avoided.
