Example 1
Referring to fig. 1 and fig. 3, embodiment 1 provides a method for monitoring the construction of a formwork member based on a pulse laser ranging device, which is characterized by comprising the following steps:
fixedly mounting a plurality of pulse laser ranging devices 1 on a reference object, and enabling the pulse laser ranging devices 1 to be positioned on the side part of a template component to be measured;
the pulse laser ranging device 1 is used for measuring the horizontal distance between the template component to be measured and the template component in real time, and transmitting the measured horizontal distance to the central processing module 2 so as to monitor the horizontal displacement condition of the template component to be measured relative to a reference object in real time;
when the horizontal distance measured by the pulse laser ranging device 1 exceeds a preset threshold value in the central processing module 2, the central processing module 2 activates the alarm module 3 to send out an alarm.
During specific setting, the transmitting end of the pulse laser ranging device 1 vertically transmits pulse laser to the outer surface of the template component to be measured, and after the pulse laser is reflected by the outer surface of the template component to be measured, the receiving end of the pulse laser ranging device 1 receives the pulse laser, so that the real-time horizontal distance between the pulse laser ranging device 1 and the template component to be measured is calculated.
The information output end of the pulse laser ranging device 1 is electrically connected with the signal input end of the central processing module 2, so that the real-time horizontal distance is transmitted to the central processing module 2. When the real-time horizontal distance exceeds the threshold value stored in the central processing module 2, the central processing module 2 outputs an alarm signal to the signal input end of the alarm module 3 through the signal output end thereof, so as to trigger the alarm module 3 to alarm. The construction method has the advantages that the implementation personnel can reinforce and adjust the load before accidents happen, and further the construction safety of the template component is improved.
As a preferred embodiment, in this embodiment 1, the alarm module 3 is a communication module electrically connected to the signal output end of the central processing module 2, and when the communication module is activated by the central processing module 2, the communication module is configured to send an alarm message to the mobile terminal. The implementer can also realize the alarm effect by replacing the communication module with a buzzer and/or an indicator light electrically connected with the central processing module 2.
In this embodiment 1, the template member to be measured is specifically the column template 41.
The above-mentioned reference object mainly functions as a fixing base 71 of the pulse laser distance measuring device 1, and should have good stability, in this embodiment 1, the above-mentioned reference object is a concrete column 5 which has been cast on the construction site of the project, and the pulse laser distance measuring device 1 is fixedly connected with the reference object through a connecting structure 6. In another embodiment, the reference is a pole.
The pulse laser distance measuring device 1 is often fixed on a reference object in advance and then the template component is installed, and after the pulse laser distance measuring device 1 is fixed, the position adjustment is difficult to realize, and the emitting end of the pulse laser distance measuring device is difficult to ensure to be vertically aligned to the part of the template component, which is easy to generate local deformation or mold expansion.
Therefore, as a preferred embodiment, referring to fig. 4, in this embodiment 1, the connecting structure 6 includes a first sliding table 61, a second sliding table 62 and a fixed table 63 for fixedly connecting to the reference object, a first sliding groove 64 extending along a first direction is formed on the fixed table 63, the first sliding table 61 is slidably connected to the first sliding groove 64 along the extending direction of the first sliding groove 64, a second sliding groove moving groove 65 extending along a second direction is further formed on the first sliding table 61, the second sliding table 62 is slidably connected to the second sliding groove moving groove 65 along the extending direction of the second sliding groove moving groove 65, and the pulsed laser ranging device 1 is fixedly connected to the second sliding table 62, wherein the first direction and the second direction are coplanar and perpendicular to each other.
In this embodiment 1, the first direction is parallel to the vertical direction, and the second direction is parallel to the transverse direction.
The operator can move and adjust the position of the emitting end of the pulsed laser ranging device 1 in the vertical or horizontal direction through the first sliding table 61 and the second sliding table 62, so as to ensure that the emitting end can be aligned with the part of the template component, where local deformation or mold expansion is easy to occur.
Further, after the position of the pulse laser ranging device 1 is adjusted by using the first sliding table 61 and the second sliding table 62, the pulse laser ranging device needs to be locked, so that the pulse laser ranging device can be located at a fixed position in a long-term monitoring process, and monitoring and error reporting are avoided. Wherein, the operator can use the nut-screw pair to precisely control the movement of the first sliding table 61 and the second sliding table 62. However, in practical engineering, we find that: for the nut screw pair, the requirement for maintenance is high, meanwhile, the locking performance is limited, a driving part for driving the screw to rotate needs to be configured on the first sliding table 61 and the second sliding table 62, the weight of the whole connecting structure 6 is high, the requirement for the connection stability between the fixed table 63 and the concrete column 5 is high, and the nut screw pair is not suitable for use.
Therefore, referring to fig. 5, in embodiment 1, each of the first sliding table 61 and the second sliding table 62 is provided with a locking assembly capable of contacting with the groove walls at two sides of the corresponding sliding groove to generate a friction force, so as to lock the first sliding table 61 and the second sliding table 62, the locking assembly is mainly composed of a base 71 for fixing with the first sliding table 61 and the second sliding table 62, and a threaded rod 72 penetrating through the base 71 and having two ends extending out of the base 71, the threaded rod 72 is fixedly connected with the base 71, two ends of the threaded rod 72 are respectively in threaded connection with a friction contact head 73, and the friction contact heads 73 at two ends can contact with the groove walls at two sides of the corresponding sliding groove through the rotation of the threaded rod 72, so as to generate a friction force for locking the first sliding table 61 and the second sliding table 62.
When the preset position is reached, the operator only needs to screw out the friction contact heads 73 at both sides to make them contact with the groove walls at both sides of the sliding groove, so as to generate friction force, and lock the first sliding table 61 and the second sliding table 62, so as to lock the position of the pulsed laser distance measuring device 1.
In addition, regarding the fixing manner between the fixing table 63 and the reference object, in this embodiment 1, a plurality of anchoring reinforcing bars anchored in the reference object are fixedly connected to the fixing table 63.
Example 2
Referring to fig. 2, embodiment 2 is substantially the same as embodiment 1, and the main difference between them is that; the specific template component to be tested is different, and in embodiment 2, the template component to be tested is the formwork support upright rod 42.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
