Description

Technical Field

[0001] The utility model relates to the technical field of building construction, municipal engineering and highway engineering, in particular to a safety monitoring device for a concrete formwork support system of a box culvert. Background Technique

[0002] At present, the monitoring methods for the deformation of the formwork support system in concrete formwork mainly include conventional measurement monitoring and intelligent monitoring of high formwork supports. Conventional measurement monitoring is to set monitoring points under the beam and slab, and then set up a theodolite for measurement. This measurement method is relatively dangerous and the internal points cannot be seen through, making it difficult to achieve the monitoring effect. Intelligent monitoring of high formwork supports is achieved by comprehensively using Internet of Things technology. This method is safe and highly automated, but it is expensive and not conducive to popularization and application in ordinary projects. In view of the above problems, research has been carried out based on the existing devices in the project. Therefore, we propose a safety monitoring device for a concrete formwork support system of a box culvert. Content of the Utility Model

[0003] To solve the above technical problems, the utility model proposes a safety monitoring device for a concrete formwork support system of a box culvert.

[0004] The technical solution of the utility model is realized as follows:

The column clamping device is used to be fixed on the vertical pole of the formwork support system to be detected. The fixing device fixes the conversion cloud platform on the column clamping device. The prism is installed on the conversion cloud platform. The fixing device is arranged in a "T" shape. Both ends of the fixing device located on the same straight line are provided with conversion cloud platforms, and the other end of the fixing device is connected to the column clamping device.

[0006] Furthermore, the fixing device includes a longitudinal part and a transverse part vertically fixed in the middle of one side of the longitudinal part.

[0007] Furthermore, both ends of the longitudinal part are respectively connected to the two conversion cloud platforms through a first length adjusting device and a second length adjusting device.

[0008] Further, the longitudinal part includes a first longitudinal part and a second longitudinal part which are symmetrically distributed up and down. The transverse part includes a first transverse part and a second transverse part which are symmetrically distributed up and down. The first transverse part is vertically fixed at the bottom end of the first longitudinal part, and the second transverse part is vertically fixed at the top end of the second longitudinal part. Both the first transverse part and the second transverse part are in a semi-cylindrical structure. A sleeve is vertically installed on the column-holding device, and both the first transverse part and the second transverse part are inserted into the sleeve.

[0009] Further, the sleeve includes a main pipe body, a first pipe body and a second pipe body. One end of the main pipe body is fixedly connected to the column-holding device. One end of the first pipe body is rotatably installed at the other end of the main pipe body. One end of the second pipe body is rotatably installed at the other end of the first pipe body. Inner thread segments are provided on the inner wall surfaces of the first pipe body and the second pipe body near one end of the main pipe body. Outer thread segments that cooperate with the inner thread segments are provided on the circumferential surfaces of the first transverse part and the second transverse part, and the outer thread segments on the first transverse part and the second transverse part are staggeredly distributed in the length direction.

[0024] Both ends of the longitudinal part 4.1 and the two conversion cloud platforms 2 are respectively connected by a first length adjusting device 5 and a second length adjusting device 6. Among them, as one embodiment of the first length adjusting device 5 and the second length adjusting device 6, the first length adjusting device 5 and the second length adjusting device 6 can be a spliced rod structure, and the connection between the spliced rod structures is realized through thread fitting. This is prior art and will not be elaborated here.

[0025] Among them, the longitudinal part 4.1 includes a first longitudinal part 4.1.1 and a second longitudinal part 4.1.2 that are symmetrically distributed up and down. The transverse part 4.2 includes a first transverse part 4.2.1 and a second transverse part 4.2.2 that are symmetrically distributed up and down. The first transverse part 4.2.1 is vertically fixed at the bottom end of the first longitudinal part 4.1.1, and the second transverse part 4.2.2 is vertically fixed at the top end of the second longitudinal part 4.1.2.
