Problems solved by technology

The settlement of high formwork formwork is one of the main monitoring parameters. At present, the main method is to use optical instruments such as theodolite or level to observe the settlement. This type of method cannot realize real-time monitoring, and the settlement of the internal formwork blocked by the line of sight is often impossible. Observation; there is also a method of monitoring by contact displacement gauge on the market, but this method is easily affected by wind load

Embodiment 1

[0016] Embodiment one: if figure 1 , 4 As shown, a high formwork template settlement monitoring device includes a support frame 100 for supporting the formwork, and a fiber grating static level 200 (model LH-FBG-HL ), the fiber grating static levels are located at the same height at the upper end of the pole 110, and the fiber grating static levels at the same end of the pole are connected in series through the vent pipe and the liquid pipe, that is, all the fiber grating static levels located at the upper end of the pole are passed through The gas pipe 300 and the liquid pipe 400 are connected in series, and the fiber grating static level is connected with the fiber grating demodulator through an optical fiber, so that the liquid and gas inside each fiber grating static level can flow with each other, and the fiber grating static level after communication The liquid level in the level will always remain at the same level. When the vertical rod at the monitoring point settles...

Embodiment 2

[0023] Embodiment two: if figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the fiber grating static level 200 is installed at the lower end of the pole, then the settlement monitoring value of the monitoring point at this time is mainly the deformation of the foundation under the column, and the monitoring value can be used for accurate It is difficult to judge the deformation of the formwork foundation accurately, but it is difficult to judge whether the erection quality of the formwork support frame is qualified, such as whether there is deformation of the frame caused by too large connection joints of vertical poles or loose connection of other components.

Embodiment 3

[0024] Embodiment three: as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a fiber grating static level 200 is installed at the upper and lower ends of the column of the support frame, and all the fiber grating static levels positioned at the upper end of the vertical pole pass through the vent pipe 300 and the liquid. The tubes 400 are connected in series, and all the fiber grating static levels located at the lower end of the pole are also connected in series through the vent tube 300 and the liquid tube 400. This method will objectively capture and record the settlement deformation of the template support frame, and at the same time accurately The settlement caused by the deformation of the support frame and the deformation of the foundation can be obtained, which can be used to analyze the reasons for the abnormal internal stress of the support members and the abnormal operation of the high-support formwork, which is more conducive to the...

Abstract

The invention relates to a monitoring device and method for high-supported formwork template settlement. The device comprises a support frame for supporting a template, the upper ends or the lower ends or the upper and the lower ends of a plurality of vertical rods on the support frame are provided with optical fiber grating static force levels, the optical fiber grating static force levels, whichare positioned at the same ends of the vertical rods, are connected in series with a liquid conveying pipe through a gas conveying pipe, and the optical fiber grating static force levels are connected with optical fiber grating demodulators through optical fiber. By the monitoring device for template support frame foundation settlement, the problems that the high-supported formwork template settlement in the market is unable to be monitored in real time and observation points inside the template are unable to be measured and easily influenced by wind load are solved, high-precision real-timemonitoring can be carried out on settlement amount respectively caused by support frame deformation, foundation deformation or by the combined action of the support frame deformation and the foundation deformation, the high-supported formwork template collapse and unstable accidents are prevented from occurrence, the potential safety hazard is timely eliminated, and the personal safety of construction workers is ensured.

Description

technical field [0001] The invention relates to a settlement monitoring device and a monitoring method for a high formwork formwork, belonging to the field of high formwork monitoring in building construction. Background technique [0002] With the development of construction technology, high formwork is widely used in the construction of cast-in-place concrete structures. In the construction of cast-in-place concrete structures, engineering accidents of formwork collapse often occur, and the risk of collapse of high-support formwork is much greater than that of conventional formwork, which accounts for a higher proportion of engineering accidents of formwork collapse. The main reasons for the collapse safety accidents of the high-span formwork are various, such as the excessive load of the high-span formwork, the excessive deformation of the high-span formwork itself, and the settlement of the foundation of the support frame of the high-span formwork. Due to the above reas...
