Technical Field

[0001] This application relates to the technical field of settlement observation points, and in particular to a pre-embedded, detachable L-shaped settlement observation point. Background Technology

[0002] L-shaped settlement observation point embedded parts are placed inside the building structure during the initial construction phase, providing stable and reliable benchmarks for settlement monitoring. Regularly observing these benchmarks allows for accurate measurement of building settlement, ensuring the accuracy of monitoring data. Settlement monitoring is a crucial means of assessing building structural safety; by monitoring building settlement, signs of structural deformation or damage can be detected promptly, allowing for appropriate preventative and remedial measures to ensure the overall stability and safety of the building. During construction, L-shaped observation points help monitoring personnel conduct precise measurements at critical locations such as corners, edges, or areas with complex stress. Regularly measuring changes in the L-shaped observation points allows for timely detection and correction of construction deviations, ensuring the quality of building construction.

[0003] However, traditional L-shaped settlement observation point embedded parts have the following disadvantages:

[0004] The installation of traditional L-shaped settlement observation point pre-embedded parts requires drilling holes in the column and installing rebar, which is very cumbersome and reduces the installation efficiency of L-shaped settlement observation points. Utility Model Content

[0005] To address the above shortcomings, the purpose of this utility model is to provide a pre-embedded, detachable L-shaped settlement observation point, which solves the problems of traditional L-shaped settlement observation point pre-embedded parts requiring drilling holes in the column, causing damage to the column, and the low installation efficiency of L-shaped settlement observation points.

[0006] To achieve the above objectives, this utility model provides a pre-embedded, detachable L-shaped settlement observation point, comprising an L-shaped settlement observation point body. The L-shaped settlement observation point body includes a first pre-embedded component, a second pre-embedded component, an L-shaped rod, and an observation point component. The second pre-embedded component includes a positioning rib and a first screw portion located at one end of the positioning rib. The first pre-embedded component includes a pre-embedded sleeve, through which a connecting screw hole is provided for connection with the first screw portion. The L-shaped rod includes a long extension rod and a short extension rod arranged perpendicular to the long extension rod. One end of the long extension rod is provided with a second screw portion adapted to the connecting screw hole, and the top end of the short extension rod is provided with an installation hole. The observation point component includes a round head and a connecting rod connected to the installation hole.

[0007] As a preferred embodiment of this utility model, the other end of the positioning rib is provided with a Y-shaped reinforcing rib.

[0008] As a preferred embodiment of this utility model, the outer wall of the pre-embedded sleeve is provided with a plurality of evenly arranged anti-slip grooves.

[0009] As a preferred technical solution of this utility model, the long extension rod is provided with a wrench insertion hole that runs through both sides of it.

[0010] As a preferred embodiment of this utility model, the wrench insertion hole has a flat hole structure.

[0011] As a preferred embodiment of this utility model, the inner wall of the mounting hole is provided with an internal thread, and the connecting rod is provided with an external thread that matches the internal thread of the mounting hole.

[0012] As a preferred technical solution of this utility model, the inner wall of the mounting hole is provided with an axial sliding groove extending along its axis, the bottom end of the axial sliding groove is provided with a limiting groove extending around the center of the mounting hole on the hole wall, and the connecting rod is provided with a sliding pin that can slide and connect with the axial sliding groove and the limiting groove.

[0013] As a preferred embodiment of this utility model, a spring is provided inside the mounting hole.

[0014] Compared with existing technologies, this utility model has the following beneficial effects:

[0015] (1) The pre-embedded detachable L-shaped settlement observation point of this utility model is equipped with positioning bars and pre-embedded sleeves for pre-embedding in the concrete structure. It does not require drilling holes in the already cast columns and beams for rebar installation, thus avoiding damage to the steel bars in the concrete structure during drilling and affecting the quality of the columns and beams. This solves the problem of damage to the columns and beams and affecting the building quality during the installation of the L-shaped settlement observation point in the prior art.

[0016] (2) The embedded detachable L-shaped settlement observation point of this utility model has a straight pipe structure for the embedded sleeve, which is set through the template. The L-shaped rod is detachably connected to the embedded sleeve through the second screw part. When the template needs to be removed, the L-shaped rod only needs to be removed, and the template can be taken out outward along the axial direction of the embedded sleeve. The template is easy to remove and solves the problem in the prior art that when the long rod section of the L-shaped settlement observation point is embedded in the concrete structure, the vertical rod section of the L-shaped settlement observation point will block the template and make it inconvenient to remove the template.

[0017] (3) The pre-embedded detachable L-shaped settlement observation point of this utility model is detachably connected to the L-shaped rod through the mounting hole of the connecting rod. Different models of observation point components can be installed according to the actual use, which has good adaptability and meets the use needs of on-site construction.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1

[0034] Reference Figures 1-6As shown, this embodiment provides a pre-embedded detachable L-shaped settlement observation point, including an L-shaped settlement observation point body 1. The L-shaped settlement observation point body 1 includes a first pre-embedded component 2, a second pre-embedded component 5, an L-shaped rod 3, and an observation point component 4. The second pre-embedded component 5 includes a positioning rib 51 and a first screw part 52 located at one end of the positioning rib 51. The positioning rib 51 and the first screw part 52 are placed in a mold for pouring concrete structure, and the pre-embedded sleeve 21 is tied to the steel reinforcement structure in the mold by steel wire or iron wire. The components are fixed and then concrete is poured to form concrete columns and beams, so that the second embedded component 5 is combined with the concrete structure. The first embedded component 2 includes an embedded sleeve 21, and a connecting screw hole 22 for connecting to the first screw part 52 is provided through the embedded sleeve 21. The connecting screw hole 22 of the embedded sleeve 21 is threadedly connected to the first screw part 52. The inner end of the embedded sleeve 21 is placed in the mold for pouring the concrete structure, and a hole is opened on the mold so that the outer end of the embedded sleeve 21 extends outward to the outside of the mold.

[0035] The L-shaped rod 3 includes a long connecting rod 31 and a short connecting rod 32 arranged perpendicular to the long connecting rod 31. One end of the long connecting rod 31 is provided with a second screw part 33 that is adapted to the connecting screw hole 22. The top end of the short connecting rod 32 is provided with a mounting hole 34. The L-shaped rod 3 is threadedly connected to the pre-embedded sleeve 21 through the second screw part 33, and the short connecting rod 32 is vertically upward.

[0036] The observation point assembly 4 includes a round head 41 and a connecting rod 42 connected to the mounting hole 34. The connection of the connecting rod 42 to the mounting hole 34 allows the observation point assembly 4 to be detached from the L-shaped rod 3.

[0037] The pre-embedded detachable L-shaped settlement observation point of this utility model is equipped with positioning bars 51 and pre-embedded sleeves 21 for pre-embedding in the concrete structure. It eliminates the need to drill holes in the already cast columns and beams for rebar installation, avoiding damage to the steel bars in the concrete structure during drilling and thus affecting the quality of the columns and beams. This solves the problem of damage to columns and beams during the installation of L-shaped settlement observation points in the prior art, which affects the building quality.

[0038] Moreover, the pre-embedded sleeve 21 is a straight pipe structure that passes through the template. The L-shaped rod 3 is detachably connected to the pre-embedded sleeve 21 through the second screw part 33. When it is necessary to dismantle the template, it is only necessary to remove the L-shaped rod 3, and the template can be taken out outward along the axial direction of the pre-embedded sleeve 21. The dismantling is convenient and solves the problem in the prior art that when the long rod section of the L-shaped settlement observation point is pre-embedded in the concrete structure, the vertical rod section of the L-shaped settlement observation point will block the template and make it inconvenient to dismantle the template.

[0039] Furthermore, the observation point assembly 4 is detachably connected to the mounting hole 34 of the L-shaped rod 3 via the connecting rod 42. Different models of observation point assemblies 4 can be installed according to actual usage conditions, which has good adaptability and meets the usage requirements of on-site construction.

[0040] Specifically, refer to Figure 5 The other end of the positioning rib 51 is provided with a Y-shaped reinforcing rib 53. The Y-shaped reinforcing rib 53 is fixed to the steel bars in the concrete structure by iron wire. After the Y-shaped reinforcing rib 53 hardens together with the concrete structure, the two branches of the Y-shaped reinforcing rib 53 can be firmly connected to the concrete and are not easy to loosen, ensuring that the embedded part is firmly fixed in the concrete structure.

[0041] Specifically, refer to Figure 2 The outer wall of the pre-embedded sleeve 21 is provided with multiple evenly arranged anti-slip grooves 23. When the pre-embedded sleeve 21 is rotated by hand to connect with the first screw part 52 at one end of the positioning rib 51, the anti-slip grooves 23 have an anti-slip function. Moreover, when the concrete is poured, the concrete structure will fill the anti-slip grooves 23 of the pre-embedded sleeve 21. After the concrete hardens, the pre-embedded sleeve 21 can be firmly fixed to the concrete and is not easy to fall off.

[0042] Specifically, refer to Figure 3 The long extension rod 31 is provided with a wrench insertion hole 35 that runs through both sides of it. The wrench insertion hole 35 has a flat hole structure. When the L-shaped rod 3 is installed on the pre-embedded sleeve 21, a long rod can be passed through the wrench insertion hole 35 and then rotated to easily drive the L-shaped rod 3 to rotate, so that the second screw part 33 is threadedly connected to the connecting screw hole 22 of the pre-embedded sleeve 21, which saves time and effort and facilitates the disassembly and assembly of the L-shaped rod 3.

[0043] Specifically, refer to Figure 6 The inner wall of the mounting hole 34 is provided with an internal thread, and the connecting rod 42 is provided with an external thread that matches the internal thread of the mounting hole 34. The connecting rod 42 and the short rod 32 are connected by threads, which makes disassembly and assembly convenient and the connection firm.

[0044] In practical use:

[0045] Positioning rib 51 is horizontally placed inside the mold, and the positioning rib 51 and Y-shaped reinforcing rib 53 are fixed to the reinforcing bars inside the mold by means of wire or other structures. Next, the pre-embedded sleeve 21 is passed through the opening on the template and connected to the first threaded part 52 of the positioning rib 51. After the concrete is poured in the mold, the second threaded part 33 of the L-shaped rod 3 is threaded to the outer end of the pre-embedded sleeve 21. Then, the connecting rod 42 of the observation point assembly 4 is threaded to the mounting hole 34 on the short rod 32 of the L-shaped rod 3. The L-shaped rod 3 and the pre-embedded sleeve 21 are detachably connected, which facilitates the disassembly of the template. The observation point assembly 4 and the L-shaped rod 3 are detachably connected, which facilitates the replacement of the observation point assembly 4 and has good adaptability.

[0046] Example 2

[0047] The technical solution of this embodiment is largely the same as that of Embodiment 1, except that the connection method between the L-shaped rod 3 and the observation point assembly 4 is different. (Refer to...) Figures 7-9 As shown, the inner wall of the mounting hole 34 is provided with an axial groove 9 extending along its axis. The bottom end of the axial groove 9 is provided with a limiting groove 6 extending circumferentially around the center of the mounting hole 34. The connecting rod 42 is provided with a sliding pin 7 that can slide with the axial groove 9 and the limiting groove 6. In this embodiment, after the observation point assembly 4 is inserted into the mounting hole 34 on the short connecting rod 32 through the connecting rod 42, it is rotated so that the sliding pin 7 on the connecting rod 42 slides from the axial groove 9 on the wall of the mounting hole 34 into the limiting groove 6, thereby axially limiting the sliding pin 7 and the connecting rod 42, thus axially limiting the observation point assembly 4 and preventing the observation point assembly 4 from falling off. The observation point assembly 4 can be quickly installed on the L-shaped rod 3.

[0048] Specifically, refer to Figure 7 A spring 8 is provided in the mounting hole 34. The spring 8 can apply an upward elastic force to the connecting rod 42 of the observation point assembly 4, causing the sliding pin 7 to push upward, increasing the friction between the sliding pin 7 and the upper groove wall of the limiting groove 6, which can prevent the sliding pin 7 from rotating, thereby preventing the observation point assembly 4 from rotating and causing the sliding pin 7 to slide from the limiting groove 6 into the axial sliding groove 9, causing the observation point assembly 4 to fall off.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
