Description

Technical Field

[0001] This application relates to the field of reference frame technology, and in particular to a mechanically stabilized reference frame for observing settlement of building structures. Background Technology

[0002] In civil engineering and building construction, the erection of static load reference beams is a crucial step. Reference piles, a concept in surveying, also known as benchmark points, are primarily used in static load tests to erect reference beams. A typical reference pile system consists of a base and a support frame. The base is driven into the foundation, and the reference beam is placed on the support frame, which supports it. However, because the height of the support frame is fixed, it can only accommodate reference beams of a specific height. For reference beams with incompatible heights, it is usually necessary to dig a pit in the ground and place the base in the pit to adapt to the required height, a cumbersome and inefficient operation. (See Chinese utility model patent publication number [insert patent number here]).

[0003] A search revealed a reference pile for erecting a static load reference beam, with Chinese patent publication number CN221989411U. This patent has the effect of reducing the depth of reference pile settlement.

[0004] Although the aforementioned patent can reduce the depth of settlement of the benchmark pile, it requires the support rod and mounting base to be disassembled and stored separately during daily storage and transportation, which greatly increases the transportation cost. At the same time, when the support rod and mounting base are connected and transported by workers over short distances, the support rod is also prone to deformation and damage due to collisions.

[0005] In response to the above situation, technological innovation should be carried out based on the existing equipment. Utility Model Content

[0006] To address the issues of high transportation costs and the vulnerability of support rods to deformation and damage during short-distance transport by workers after connection to the mounting base, this application provides a mechanically stabilized reference frame for monitoring building settlement.

[0007] The mechanically stabilized reference frame for observing settlement of building structures provided in this application adopts the following technical solution:

[0008] A mechanically stabilized reference frame for observing settlement of building structures includes a pole with a tapered lower end. The outer surface of the pole has a receiving groove extending to its upper surface, and the outer surface also has graduations. A first through groove communicating with the receiving groove is also present on the outer surface of the pole. A collar is slidably fitted onto the outer surface of the pole, and the collar has a first opening. Two mounting plates are fixedly connected to the inner wall of the collar, and a connecting shaft is fixedly connected between the two mounting plates. A support rod is rotatably fitted onto the outer surface of the connecting shaft, and a fixing component is mounted on the support rod. A rotating groove is formed inside the collar, and an auxiliary fixing component is mounted on the rotating groove.

[0009] By adopting the above technical solution, the support rod can be retracted into the interior of the upright when not in use, thereby reducing the space occupied during transportation.

[0010] Preferably, the auxiliary fixing component includes a rotating ring, which is rotatably connected inside a rotating groove. The rotating groove communicates with the inside of a first opening. A second opening is provided on the rotating ring, and a sliding groove extending into the rotating groove is provided on the outer surface of the collar.

[0011] By adopting the above technical solution, the support rod can be limited and supported by the setting of the rotating ring.

[0012] Preferably, the outer surface of the collar is provided with a lever, which extends through a sliding groove into the interior of the rotating groove and is fixedly connected to the rotating ring.

[0013] By adopting the above technical solution, the position of the rotating ring can be conveniently controlled using the lever.

[0014] Preferably, the lever is slidably connected to the sliding groove, and the end of the support rod located inside the storage groove has a docking groove.

[0015] By adopting the above technical solution, the rotation range of the lever can be limited by the sliding groove.

[0016] Preferably, the outer surface of the collar is provided with a second through groove, which is aligned with the mating groove and the first through groove.

[0017] By adopting the above technical solution, the alignment of the three grooves can facilitate subsequent fixing.

[0018] Preferably, a locking screw is threaded inside the second through groove, the diameter of the first through groove and the mating groove is larger than the diameter of the locking screw, a sleeve is slidably fitted on the outer surface of the upright, and a first disc is fixedly connected to the lower surface of the sleeve.

[0019] By adopting the above technical solution, the support rod can be fixed by inserting a locking screw into the docking groove.

[0020] Preferably, a connecting rod is fixedly connected to the lower surface of the first disk, and a second disk is fixedly connected to the lower end of the connecting rod.

[0021] By adopting the above technical solution, the height of the first disc can be raised by using the second disc, thereby reducing the difficulty of operating the fixing bolts.

[0022] Preferably, a fixing bolt is provided on the outer surface of the first disc, and the end of the fixing bolt is threaded through the first disc and contacts the outer surface of the upright.

[0023] By adopting the above technical solution, the position of the first disc can be locked by fixing bolts, and the fixing bolts can be protected by the design of the first disc enclosing the fixing bolts.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The storage slot can provide space for storing the support rod, and the mounting plate and connecting shaft can realize the rotation function of the support rod. This allows the support rod to be stored inside the upright when not in use, thereby reducing the space occupied during transportation and solving the problem of disassembling the support rod to avoid collision deformation during short-distance transportation.

[0026] 2. The design of encasing the fixing bolts inside the first disc can prevent deformation and damage caused by accidental contact with exposed bolts during transportation, thus ensuring the safety of the equipment. At the same time, the rotating ring can not only limit the movement of the support rod after it is stored to prevent shaking, but also provide simple support when the support rod is unfolded, making it easy to fix it with the locking screw later.

[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] This application discloses a mechanically stabilized reference frame for observing the settlement of building structures.

[0036] Reference Figures 1-4 A mechanically stabilized reference frame for observing settlement of building structures includes a pole 1 with a tapered lower end. The outer surface of the pole 1 has a storage groove 2 extending to its upper surface, providing storage space. The outer surface of the pole 1 has graduations 3 and a first through groove 4 communicating with the inside of the storage groove 2. The first through groove 4 facilitates the insertion of a screw for fixing. A collar 5 is slidably fitted on the outer surface of the pole 1, and the vertical movement of the collar 5 adjusts the height of a support rod 9 and provides space for the installation of the support rod 9.

[0037] The collar 5 has a first opening 6. Two mounting plates 7 are fixedly connected to the inner wall of the collar 5. A connecting shaft 8 is fixedly connected between the two mounting plates 7. A support rod 9 is rotatably mounted on the outer surface of the connecting shaft 8. The connecting shaft 8 provides rotation space for the support rod 9. A fixing component 10 is provided on the support rod 9. A rotating groove 11 is opened inside the collar 5. An auxiliary fixing component is provided on the rotating groove 11. The storage groove 2 can provide space for storing the support rod 9. At the same time, the mounting plates 7 and the connecting shaft 8 realize the function of rotating the support rod 9. This allows the support rod 9 to be stored inside the upright 1 when not in use, thereby reducing the space occupied during transportation and solving the problem that the support rod 9 needs to be disassembled to avoid collision deformation during short-distance transportation.

[0038] Furthermore, the auxiliary fixing component includes a rotating ring 12, which is rotatably connected to the inside of a rotating groove 11. The rotating groove 11 communicates with the inside of the first opening 6. The rotating ring 12 limits the support rod 9 when it is retracted and supports it when it is extended. A second opening 13 is provided on the rotating ring 12. A sliding groove 14 extending into the rotating groove 11 is provided on the outer surface of the collar 5. A lever 15 is provided on the outer surface of the collar 5. The position of the rotating ring 12 can be easily controlled by the lever 15. The lever 15 extends into the rotating groove 11 through the sliding groove 14 and is fixedly connected to the rotating ring 12. The lever 15 is slidably connected to the sliding groove 14. A docking groove 16 is provided at one end of the support rod 9 located inside the storage groove 2. A second through groove 17 is provided on the outer surface of the collar 5. The second through groove 17 is aligned with the docking groove 16 and the first through groove 4. A locking screw 18 is threaded inside the second through groove 17. The locking screw 18 locks the collar 5 and the support rod 9.

[0039] The diameter of the first through groove 4 and the docking groove 16 is larger than the diameter of the locking screw 18. A sleeve 19 is slidably fitted on the outer surface of the upright 1. A first disc 20 is fixedly connected to the lower surface of the sleeve 19. A connecting rod 21 is fixedly connected to the lower surface of the first disc 20. A second disc 22 is fixedly connected to the lower end of the connecting rod 21. A fixing bolt 23 is provided on the outer surface of the first disc 20. The end thread of the fixing bolt 23 passes through the first disc 20 and contacts the outer surface of the upright 1. By covering the fixing bolt 23 inside the first disc 20, the bolt can be prevented from being exposed during transportation and thus avoids accidental contact that could cause deformation and damage, ensuring the safety of the equipment. At the same time, the rotating ring 12 can not only limit the support rod 9 after it is stored to prevent shaking, but also provide simple support when the support rod 9 is unfolded, making it easier to fix it using the locking screw 18 later.

[0040] The fixing component 10 mentioned in the text is prior art, which specifically includes a connecting rod, a mounting nut, a placement rod, a placement gap, a placement area, and a fixing component. For details, please refer to the auxiliary placement component in patent publication number CN221989411U. Since it is not the main direction of improvement, it is not shown in detail in the figure and will not be described in detail here. The collar 5 mentioned in the text has a double-layer structure, which is formed by connecting the upper cover and the lower seat with screws. The rotating groove 11 is milled on the upper surface of the lower seat. After the rotating ring 12 is inserted, the upper cover is covered to form a closed cavity. At the same time, in order to improve the stability of the connection between the locking screw 18 and the mating groove 16, the end of the locking screw 18 can be set as a frustum shape, and the mating groove 16 can be set as a corresponding conical countersunk hole, thereby eliminating the gap and improving the connection stability.

[0041] The implementation principle of a mechanically stabilized reference frame for observing settlement of building structures according to an embodiment of this application is as follows: When using the reference frame, first loosen the fixing bolt 23, and adjust the height of the sleeve 19, the first disc 20, and the second disc 22 in conjunction with the scale 3 on the upright 1. After adjustment, tighten the fixing bolt 23 to complete the adjustment of the height of the second disc 22. Then, insert the upright 1 into the ground so that the ground contacts the lower surface of the second disc 22. It can be rotated by controlling the lever 15. Since the lever 15 is slidably connected to the sliding groove 14, and the sliding groove 14 is only opened in a fan shape of ninety degrees, the lever... The lever 15 can only rotate 90 degrees. When the lever 15 rotates, it will drive the rotating ring 12 to rotate synchronously. After the rotating ring 12 rotates, the second opening 13 is aligned with the first opening 6, releasing the lock on the support rod 9. At this time, the support rod 9 is rotated so that its end is tilted upward. Then the lever 15 is operated again to make the second opening 13 and the first opening 6 misaligned. The rotating ring 12 is used to support the support rod 9. Then the locking screw 18 is screwed into the first through groove 4 and the docking groove 16 through the second through groove 17. The support rod 9 is fixed by means of the locking screw 18. Then it can be fixed by means of the fixing component 10.

[0042] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
