Description

Technical Field

[0001] The present invention belongs to the technical field of deformation monitoring, and more specifically, relates to a device and method for monitoring deformation of a formwork support. Background Art

[0002] In the construction of cast-in-place concrete structures, tall formwork support systems are widely used, and formwork collapse is the most common engineering accident in formwork support systems. The causes of collapse accidents involve many aspects, such as: excessive load on high-support formwork, excessive deformation of formwork support, settlement deformation of formwork support foundation, etc. One of the main means to prevent formwork support collapse is to monitor the various characteristic deformations of the formwork support during the concrete pouring process. For example, the settlement deformation of the formwork support is one of the main monitoring parameters.

[0003] However, since the formwork supports are usually set up densely, it is difficult to monitor the deformation value of the dangerous area inside the formwork supports using conventional monitoring methods. For example, some existing monitoring methods are to measure the bottom of the formwork and above the support by hanging a plumb ball or using a theodolite to observe the settlement. Such methods have large errors and a large monitoring workload. The poor accuracy and precision also make it impossible to quickly confirm the deformation and achieve real-time monitoring.

DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Embodiment 1: Embodiment 1 provides a template support deformation monitoring device, see Figure 1 , Figure 2 , mainly including: a load-bearing rod 1, a laser emitter 2, a vertical monitoring target 3, a horizontal monitoring target 4 and a workbench 5; the upper end of the load-bearing rod 1 is connected to the template support, the laser emitter 2 is installed in the lower area of ​​the load-bearing rod 1, and the vertical monitoring target 3 and the horizontal monitoring target 4 are both installed on the working surface of the workbench 5; the load-bearing rod 1 is used to deform together with the deformation of the template support; the laser emitter 2 is used to emit vertical laser and horizontal laser; the vertical monitoring target 3 is used to receive the horizontal laser to monitor the displacement of the template support in the vertical direction; the horizontal monitoring target 4 is used to receive the vertical laser to monitor the displacement of the template support in the horizontal direction.

[0021] Among them, see Figure 1 , Figure 2 and Figure 3 The horizontal monitoring target 4 is arranged below the laser emitter 2, and the horizontal monitoring target 4 includes a second scale reading area 10. The template support deformation monitoring device obtains the displacement data of the template support in the horizontal direction based on the reading of the vertical laser irradiation on the second scale reading area 10.

[0022] In addition, the horizontal monitoring target 4 can be rotated on the workbench 5 around a mounting point to adjust the direction of the reading axis of the horizontal monitoring target 4 .

[0023] By setting the horizontal monitoring target 4, the basic direction of the bending deformation of the load-bearing rod 1 can be visually seen, which can be used to guide the concrete pouring method.

[0024] See also Figure 1 , Figure 2 and Figure 4The vertical monitoring target 3 includes a first scale reading area 13, and the template support deformation monitoring device obtains the displacement data of the template support in the vertical direction based on the reading of the first scale reading area 13 irradiated by the horizontal laser.

[0025] In addition, the lower end of the vertical monitoring target 3 is installed on the workbench 5 through a vertical rod, and a height adjustment member 7 is provided on the vertical rod. The height adjustment member 7 is used to adjust the height of the vertical monitoring target 3; the vertical monitoring target 3 can rotate around the installation point on the workbench 5 to adjust the orientation of the vertical monitoring target 3.

[0026] The two scale reading areas can be used to conveniently and quickly read the scale of laser irradiation, and then obtain displacement data. For example, after the monitoring device is installed, the initial reading can be read first. As the template support deforms, the force-bearing rod 1 will also deform and displace, thereby driving the position of the laser emitter 2 to move. At this time, the reading on the deformed monitoring target is read again, and the difference between the two readings is the deformation value.

[0027] The formwork support deformation monitoring device may further include: a leveling component 6; a level 12 is installed on the working surface of the workbench 5, and the leveling component 6 and the level 12 are used to ensure that the workbench 5 is level. For example, a bubble level is used, and the workbench 5 is leveled by adjusting the leveling component 6 to center the bubble.

[0028] For example, see Figure 5 The leveling assembly 6 includes an adjusting rod, a leveling knob support 15, and a plurality of leveling knobs 16 installed at different positions on the leveling knob support 15; the lower end surface of the workbench 5 is connected to the adjusting rod, the lower end of the adjusting rod is installed at the central fixing point of the leveling knob support 15 (for example, a fixing screw 17 is provided at the central point of the leveling knob support 16), and the lower end surface of the leveling knob support 15 is installed on the base through a fixing rod.

[0029] In a preferred solution, the template support deformation monitoring device may also include: an alarm monitor 9; the vertical monitoring target 3 also includes a first photosensitive response area 14, and the horizontal monitoring target 4 also includes a second photosensitive response area 11. The first photosensitive response area 14 and the second photosensitive response area 11 are both connected to the alarm monitor 9 through a wire 8; the first photosensitive response area 14 is used to convert the optical signal into an electrical signal when receiving the horizontal laser, and transmit it to the alarm monitor 9; the second photosensitive response area 11 is used to convert the optical signal into an electrical signal when receiving the vertical laser, and transmit it to the alarm monitor 9; the alarm monitor 9 is used to perform a deformation alarm, such as a sound warning, to achieve the effect of warning.

[0030] The above two light-sensitive response areas, i.e., the monitoring target over-limit value areas, are composed of light-sensitive electronic components and can convert the received laser signals into electrical signals.

[0031] The length between the zero point position of the first scale reading area 13 and the upper limit position of the first light sensitive area 14 is equal to the set settlement deformation warning value, for example, the set settlement deformation warning value is 10mm. The second scale reading area 10 is a circular area, the outer boundary of the second light sensitive area 11 is a square, the circular boundary of the circular area is used as the inner boundary of the second light sensitive area 11, and the radius of the circular area is equal to the set horizontal deformation warning value. That is, if the laser irradiates the position outside the circular area and inside the square area, a deformation alarm is issued.

[0032] In addition, the template support deformation monitoring device may also include: a data processing and display unit; the vertical monitoring target 3 and the horizontal monitoring target 4 are both connected to the data processing and display unit; the data processing and display unit is used to obtain vertical deformation information based on the displacement data of the template support in the vertical direction and display it, and is used to obtain horizontal deformation information based on the displacement data of the template support in the horizontal direction and display it.

[0033] The installation of the formwork support deformation monitoring device provided in Example 1 is described below.

[0034] As the formwork support is erected, the stress-bearing rod 1 is installed in the key monitoring area of ​​the formwork support, the upper part of the stress-bearing rod 1 is pressed against the bottom of the formwork support, and the stress-bearing rod 1 is fixed to the formwork support by fasteners, and tightened firmly to eliminate factors that affect the deformation reading due to its own movement. The laser transmitter 2 is installed at the bottom of the stress-bearing rod 1, and it is firmly fixed to the stress-bearing rod 1 by special threads and ties. The workbench 5, the vertical monitoring target 3 and the horizontal monitoring target 4 are installed, and the positions of the monitoring targets are adjusted so that the laser point is aligned with the zero point position of the first scale reading area 13 in the vertical monitoring target 3, and the laser point is aligned with the center point position of the horizontal monitoring target 4. The two light-sensitive sensing areas are connected to the alarm monitor 9 through the wire 8 to form a passage. At this point, the main installation work of the formwork support deformation monitoring device is completed.

[0035] Embodiment 1 uses laser collimation to directly mark the real-time deformation readings, and sets a light-sensitive component in the warning area. When the template support is deformed and the laser is irradiated on the light-sensitive area, the light signal is converted into an electrical signal, and an alarm monitor is used to issue an alarm, thus achieving real-time and quick readings and deformation warnings. That is, the present invention can accurately, in real time and conveniently monitor the horizontal and vertical (i.e., vertical) deformation of the template support, and can also automatically issue an alarm when the deformation exceeds the warning value. In addition, the monitoring device provided in Embodiment 1 is simple in structure, easy to install, easy to operate, and highly practical.

[0036] Embodiment 2: Example 2 provides a method for monitoring deformation of a formwork support, using the formwork support deformation monitoring device as described in Example 1 to monitor the displacement of the formwork support in the vertical and horizontal directions.

[0037] In addition, the template support deformation monitoring method provided in Example 2 may also include the following steps: When the first light sensitive area and / or the second light sensitive area receives the laser, a deformation alarm is issued by using an alarm monitor; The data processing and display unit is used to obtain deformation information according to the displacement data and display it.

[0038] Since the monitoring method provided in Example 2 is implemented by using the monitoring device provided in Example 1, it can be understood by referring to the functional description of each device in Example 1, which will not be repeated here.

[0039] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
