Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a prefabricated beam monitoring device. Background Art

[0002] Prefabricated beams need to be erected between the two piers of the bridge, and simply supported temporary supports need to be installed between the prefabricated beams. The simply supported temporary supports are prefabricated beam simply supported structures. Each prefabricated beam is simply supported first, and the simply supported temporary supports can only be removed after the permanent supports bear the load.

[0003] The main problems existing in the erection process of precast beam simply supported structures are: poor longitudinal integrity of the bridge, and potential accidents such as precast beams falling and overturning under special accidental loads that endanger the safety of the project.

[0004] The current bridge is not equipped with any monitoring facilities. Due to the lack of real-time monitoring facilities, when abnormal displacement changes occur in precast beams, the safety hazards of precast beams cannot be discovered and dealt with in time. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a prefabricated beam monitoring device for real-time monitoring of a prefabricated beam simply supported structure.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A prefabricated beam monitoring device comprises a connecting box arranged between two prefabricated beams; steel pipes are respectively arranged on the left and right sides of the connecting box, one end of the steel pipe on the left side of the connecting box passes through the left prefabricated beam and is fixedly connected to the left prefabricated beam, the other end of the steel pipe on the left side of the connecting box passes through the left side of the connecting box and is fixedly connected to a first support plate, and also comprises a first spring, one end of the first spring is mounted on the support plate, and the other end of the first spring is mounted on the left inner wall of the connecting box; one end of the steel pipe on the right side of the connecting box passes through the right prefabricated beam and is fixedly connected to the right prefabricated beam, the other end of the steel pipe on the right side of the connecting box passes through the right side of the connecting box and is fixedly connected to a second support plate, and also comprises a second spring, one end of the second spring is mounted on the second support plate, and the other end of the second spring is mounted on the right inner wall of the connecting box; and also comprises a displacement sensor installed in the connecting box, the displacement sensor being used to measure the relative distance between the first support plate and the second support plate.

[0008] Furthermore, the displacement sensor is connected to a data display device via a line.

[0009] Furthermore, four steel pipes are respectively provided on the left and right sides of the connection box, and the four steel pipes are arranged in two rows and aligned.

[0010] Furthermore, the side of the connection box is provided with a plurality of through-holes for the steel pipe to pass through, and the bottom of the through-hole is provided with a notch, which is connected to the bottom of the side of the connection box, so that the steel pipe can pass through the bottom of the side of the connection box.

[0011] Furthermore, the data display device is a data storage device.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0013] When a precast beam deforms, the steel pipes within the connection box stretch or contract. Displacement sensors detect the displacement of the first and second support plates. These data are transmitted to a data display device for operator reference. The steel pipes on either side of the connection box are limited in how much they can stretch. The connection box provides support when the steel pipes reach their limit, thus protecting the two precast beams from deformation. BRIEF DESCRIPTION OF THE DRAWINGS

There are many forms of displacement sensor 6, including electromagnetic induction displacement sensor, capacitive displacement sensor, photoelectric displacement sensor, ultrasonic displacement sensor, and Hall displacement sensor. This embodiment selects any feasible one of them as the displacement sensor 6 of this scheme. Taking the electromagnetic induction displacement sensor as an example, the electromagnetic induction displacement sensor includes a coil and a magnetic field source. The coil is installed on the first support plate 4, and the magnetic field source is installed on the second support plate 5. The change in the magnetic field causes a voltage to be induced in the coil. By measuring the magnitude of the induced voltage, the relative displacement of the first support plate 4 and the second support plate 5 is determined.

[0020] The improvement of the present invention lies in the following: an expansion joint is formed between the two precast beams 9, and a connecting box 2 is installed at the location of the expansion joint. Both sides of the connecting box 2 are connected to the precast beams 9 via steel pipes 1. A first support plate 4 fixed to the left steel pipe 1 and a second support plate 5 fixed to the right steel pipe 1 are connected via displacement sensors 6. When the precast beams 9 are displaced and deformed, the steel pipes 1 within the connecting box 2 are stretched or contracted, and the displacement sensors 6 detect the displacement changes of the first support plate 4 and the second support plate 5. Furthermore, the amount of stretching of the steel pipes 1 on both sides of the connecting box 2 is limited. The connecting box 2 provides support when the steel pipes 1 are stretched to their limit, providing the two precast beams 9 with the ability to resist displacement and deformation, thereby achieving safety protection for the precast beams 9.

[0021] Furthermore, the displacement sensor 6 is connected to a data display device via a line, and the displacement data detected by the displacement sensor 6 is transmitted to the data display device to provide data reference for operators.

[0022] Furthermore, four steel pipes 1 are respectively provided on the left and right sides of the connection box 2, and the four steel pipes 1 are arranged in two rows. The four steel pipes 1 are respectively provided on the left and right sides, and the connection box 2 is more stable and has a stronger ability to resist the displacement and deformation of the prefabricated beam 9.
