Description

Technical Field

[0001] The utility model belongs to the technical field of construction monitoring devices, and in particular relates to a construction building foundation settlement monitoring device. Background Art

[0002] Building foundation refers to the load-bearing structure below the ground level of a building. It is the underground extension of the building's walls or columns, and plays the role of bearing the load of the building's superstructure and transferring it to the foundation. Among them, settlement monitoring of building foundations can be equivalent to settlement monitoring of building foundations.

[0003] The Chinese patent with the publication number CN220337976U discloses a ground settlement monitoring device for construction, including a bedrock mark outer tube and a support inner rod; the outer curved surface at the top of the bedrock mark outer tube is fixedly connected to a protection box, the side end of the inner bottom surface of the protection box is fixedly connected to a reading rod, the top of the support inner rod is fixedly connected to a support screw, the middle outer curved surface of the support screw is threadedly connected to an adjustment ring, the outer curved surface of the adjustment ring is rotatably connected to the support ring, and the side end of the support ring is fixedly connected to a reading ring; the top of the protection box is rotatably connected to an adjustment screw, the upper outer curved surface of the adjustment screw is threadedly connected to a mounting seat, the inner wall of the side end of the mounting seat is movably connected to a limited position slide rod, the lower end surface of the mounting seat is screwed to a contact switch, and the middle upper end surface of the protection box is screwed to an audible and visual warning light. This solution realizes the foundation settlement warning function and can adjust the warning distance between the contact switch and the top of the support screw.

[0004] However, in actual use, since the above scheme completes foundation settlement monitoring by having the outer tube of the bedrock marker move accordingly with the settlement of the foundation, when uneven settlement of the foundation occurs, the outer tube of the bedrock marker can only move axially along the supporting inner rod, which causes the actual moving distance of the outer tube of the bedrock marker to be less than the settlement distance. That is, the monitoring data and results obtained may not be consistent with the actual situation, and the settlement monitoring data has a large error. Utility Model Content

[0005] The utility model aims to provide a ground settlement monitoring device for building construction, so as to solve the problem that the monitoring data obtained by the existing monitoring device has large errors.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction building foundation settlement monitoring device, comprising

[0007] The support rod group includes an underground rod and a connecting rod, wherein the connecting rod is threadedly inserted into the underground rod;

[0008] The monitoring mechanism includes a fixed plate and a plurality of monitoring units arranged at intervals around the fixed plate. The fixed plate is fixed to the top of the connecting rod. The monitoring unit includes a telescopic rod group, a connecting tube, a monitoring rod and a laser rangefinder. One end of the telescopic rod group is connected to the fixed plate, and the other end of the telescopic rod group is fixed to the connecting tube. The laser rangefinder is fixed to the top of the connecting tube, and the upper end of the monitoring rod is slidably inserted into the connecting tube.

[0009] The principle and effect of this technical solution:

[0010] 1. By burying the buried rod in the bedrock or using concrete to bury the buried rod deep in the base of the ground, the absolute stillness of the buried rod is guaranteed. The range of simultaneous monitoring is expanded by connecting the rod and multiple monitoring units installed above, so as to obtain more detailed and reliable foundation settlement data.

[0011] 2. By sliding the monitoring rod under the connecting tube and installing the laser rangefinder above the connecting tube, when the foundation settles, the monitoring rod will drop under its own gravity as the foundation settles. At this time, the distance from the laser rangefinder to the top edge of the monitoring rod increases, thereby increasing the distance measured by the laser rangefinder, and then obtaining the settlement data of the foundation. By setting up multiple sets of monitoring units, the actual settlement data of the foundation can be obtained based on multiple sets of foundation settlement data within the monitoring range, and the accuracy of the calculation data can be improved, thereby improving the monitoring accuracy. That is, even if uneven settlement occurs, the final monitoring structure can be refined through the monitoring data of multiple sets of monitoring devices, thereby obtaining more accurate settlement data.

[0012] The utility model is further configured as follows: the monitoring unit also includes a spring-pressing component, the spring-pressing component includes a spring and a pressure ring, the pressure ring is fixed on the monitoring rod, and the pressure ring is slidably fitted in the connecting tube, the spring is arranged in the connecting tube, and is located above the pressure ring.

[0013] The principle and effect of this technical solution: through the setting of the spring and the pressure ring, after the foundation settles, the rebound force of the spring will drive the monitoring rod to move toward one side of the foundation, thereby avoiding the situation where the monitoring rod and the connecting tube are stuck and the monitoring rod does not move with the foundation settlement, thereby improving the reliability of monitoring.

[0014] The utility model is further configured as follows: the monitoring unit also includes an auxiliary alarm component, the auxiliary alarm component includes a movable ring and a trigger switch, the movable ring is slidably mounted outside the connecting tube, a sliding groove is provided on the side wall of the connecting tube, the trigger switch is fixed on the inner wall of the movable ring, and the trigger switch passes through the sliding groove and extends into the connecting tube, the trigger switch is located below the pressure ring, and a warning light is fixed on the top of the fixed plate.

[0015] The principle and effect of this technical solution: through the setting of the movable ring and the trigger switch, the device will automatically alarm after monitoring the foundation settlement to a certain extent, that is, the alarm amount is set. After the device is adjusted, if the foundation settles, the spring and the gravity of the monitoring rod itself will drive the monitoring rod to move downward, and at the same time drive the pressure ring to move downward, and then abut the trigger switch, so that the warning light works.

[0016] The utility model is further configured as follows: the outer wall of the connecting tube is provided with scales along the length direction of the sliding groove.

[0017] The principle and effect of the technical solution: the setting of the scale is convenient for the operator to control the alarm settlement amount of the trigger switch relative to the pressure ring after the device is installed and set up.

[0018] The utility model is further configured as follows: the telescopic rod group includes a fixed rod, a movable rod and a locking nut, one end of the fixed rod is connected to the fixed plate, the movable rod is slidably inserted into the other end of the fixed rod, the connecting tube is fixed to the end of the movable rod away from the fixed rod, the locking nut is threadedly inserted into the fixed rod, and the end of the locking nut extends to abut against the movable rod.

[0019] The principle and effect of this technical solution: by controlling the matching length of the movable rod relative to the fixed rod, the position of the connecting tube relative to the buried rod can be controlled, that is, the monitoring range of the device is controlled. The monitoring range of the device is increased by setting the movable rod and the fixed rod, and the applicability of the device is improved. At the same time, the movable rod is locked by the locking nut, so that the connecting tube remains stable during monitoring.

[0020] The utility model is further configured as follows: it also includes an adjusting mechanism, the adjusting mechanism includes an adjusting ring, a control ring and a plurality of adjusting rods corresponding to the fixed rods one by one, the adjusting ring is threadedly mounted on the connecting rod, the control ring is slidably mounted on the connecting rod and abuts against the top of the adjusting ring, one end of the adjusting rod is rotatably connected to the control ring, the other end of the adjusting rod is rotatably connected to the fixed rod, a sink groove is opened in the circumference of the bottom of the fixed plate, and the fixed rod is rotatably connected in the sink groove.

[0021] The principle and effect of the technical solution are as follows: the adjusting ring can be moved relative to the connecting rod by rotating the adjusting ring, and then the control ring abutting on the adjusting ring is controlled to move. The adjusting rod is hinged with the control ring and the fixed rod to form a crank slider mechanism, that is, the angle of the fixed rod relative to the fixed plate is controlled by the position of the adjusting ring, so that the fixed rod can be folded and stored when the device is not in use, saving space and being easy to carry. Moreover, the setting of the sink groove makes the fixed rod unable to continue to rotate in the sink groove after being rotated to a certain angle, thereby limiting the rotation amount of the fixed rod, making the device more convenient when adjusting the angle of the fixed rod, and the fixed rod can remain relatively stable without adjusting the fixed rod to the point where it cannot rotate, and has high stability.

[0022] The utility model is further configured as follows: a rotating handle is fixed on the outer wall of the adjusting ring.

[0023] The principle and effect of the technical solution: the setting of the rotary handle makes it easier for the operator to rotate the adjustment ring. BRIEF DESCRIPTION OF THE DRAWINGS
