Embodiment 1
[0045] Such as figure 1 , figure 2 , Image 6The illustrated embodiment is a reinforcement method for concrete bridge slabs 19, including 2 embedded steel plates 1, steel strips 2, 4 wing plates 3, prestressed steel plate heating devices 4, temperature sensors 5, dial indicators 6, control Device 7 and the left bearing 16 and the right bearing 17 that are used to support the concrete bridge slab; The left bearing is a fixed bearing, and the right bearing is a sliding bearing;
[0046] Such as figure 2 As shown, two wing plates are respectively connected with the upper edge and lower edge of the left part of the steel strip to form a left combined structure, and the other two wing plates are respectively connected with the upper and lower edges of the right part of the steel belt to form a right combined structure. The left composite structure is connected with one embedded steel plate, and the right composite structure is connected with another embedded steel plate; each ...
Embodiment 2
[0069] Embodiment 2 includes all structures and step parts of Embodiment 1, such as Figure 4 As shown, an alarm 14 and a memory 15 are also included, and both the alarm and the memory are electrically connected to the controller; before step 600 of Embodiment 1, a temperature sensor failure detection step is also included:
[0070] The standard temperature signal curve of the temperature sensor is set in the memory;
[0071] (9-1) The controller obtains the temperature signal curve S(t) of the temperature sensor, and the controller extracts the temperature signal value M corresponding to each time interval in S(t) 1 ,...,M n ;The serial number of the set temperature signal value is i, i=1,...,n;
[0072] (9-2) Controller Utilization Formula Calculate each temperature signal value M i The smooth rate ratio i ;
[0073] When S(t) has no intersection with the standard temperature signal curve and the ratio of each temperature signal value i If they are all outside the ra...
