Description

Technical Field

[0001] This utility model belongs to the field of building settlement monitoring technology, specifically relating to a convenient installation auxiliary device for building settlement monitoring points. Background Technology

[0002] In building settlement monitoring, settlement data is the core basis for assessing the structural safety of a building. If the vertical displacement of a building under load exceeds the limit (e.g., differential settlement of masonry structures ≤ 0.002L), it can cause structural damage such as wall cracking and beam / column deformation, or functional failures such as elevator track tilting and underground pipeline rupture. During the construction phase, monitoring is needed to control the impact of foundation pit excavation and pile foundation construction on surrounding buildings (e.g., settlement rate ≤ 2mm / day), while during the operation phase, long-term monitoring and analysis of settlement trends are needed to assist in maintenance and management.

[0003] Currently, the installation sleeve of the observation marker serves as the benchmark carrier for settlement monitoring, and its installation quality directly affects the reliability of the data. However, traditional installation auxiliary devices have the problem of cumbersome installation operations. Most devices require the use of multiple tools for positioning and fixing. For example, when using bolts for fastening or on-site welding, the position needs to be adjusted repeatedly, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient auxiliary device for the installation of building settlement monitoring points, which can easily and conveniently complete the installation of the observation marker installation sleeve.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A convenient installation auxiliary device for building settlement monitoring points includes a middle block, on which an observation mark installation sleeve is fixedly connected. Telescopic brackets are fixedly connected to both sides of the middle block, and hooks are fixedly connected to both telescopic brackets.

[0007] Furthermore, the telescopic bracket includes a threaded sleeve fixedly connected to one side of the intermediate block, a threaded rod being threadedly connected inside the threaded sleeve, one end of the threaded rod being rotatably connected to a hook, and a guide sleeve being fixedly connected to one side of the intermediate block, a guide rod being slidably connected inside the guide sleeve, one end of the guide rod being fixedly connected to a hook.

[0008] Furthermore, a cylinder is fixedly connected to the intermediate block, and the observation mark mounting sleeve is slidably connected inside the cylinder, with a locking screw threaded onto the cylinder.

[0009] Furthermore, the end of the observation mark mounting sleeve is detachably fixedly connected with a protective cover.

[0010] Furthermore, the outer side of the end of the observation mark mounting sleeve is provided with a threaded wire, and the protective cover is threadedly connected to the outer side of the threaded wire. The protective cover is made of ceramic.

[0011] Furthermore, a coating is embedded on the inner side of the hook claw, and a welding core is wrapped inside the coating. One end of the welding core is fixedly connected to an electrode connector extending to the outer side of the hook claw.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a convenient installation auxiliary device for building settlement monitoring points. By narrowing the gap between the two hooks using a telescopic bracket, the two hooks can be clamped on the outside of the two main reinforcement bars, thus making the installation of the observation mark installation sleeve relatively simple and convenient.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4As shown, a convenient installation auxiliary device for building settlement monitoring points includes an intermediate block 1, on which an observation mark installation sleeve 4 is fixedly connected. The settlement monitoring point observation mark can be assembled on the observation mark installation sleeve 4, and the assembly method is that the settlement monitoring point observation mark is threadedly connected to the observation mark installation sleeve 4.

[0023] Telescopic brackets are fixedly connected to both sides of the middle block 1, and hooks 7 are fixedly connected to both telescopic brackets. At this time, the middle block 1 is placed on one side of the steel bar, and the two hooks 7 are located on both sides of the two main bars respectively. By shrinking the distance between the two hooks 7 through the telescopic brackets, the two hooks 7 can be clamped on the outside of the two main bars, thus completing the installation of the observation mark installation sleeve 4 in a relatively simple and convenient way.

[0024] After the observation marker installation sleeve 4 is fixed, formwork is erected. When erecting the formwork, it is necessary to make holes in the formwork so that the observation marker installation sleeve 4 can extend through the formwork holes to the outside of the formwork. After the formwork is erected, concrete is poured. After the concrete is formed, the formwork is removed. After the formwork is removed, the observation marker is installed on the observation marker installation sleeve 4, and the installation of the observation marker is completed.

[0025] like Figures 1-3 As shown, in some embodiments, the telescopic support includes a threaded sleeve 8 fixedly connected to one side of the intermediate block 1. The threaded sleeve 8 has a threaded rod 9 connected internally. One end of the threaded rod 9 is rotatably connected to a hook 7. A nut 10 is welded to the outer end of the threaded rod 9 near the hook 7. The nut 10 allows the operator to rotate the threaded rod 9 with a wrench. By rotating the threaded rod 9, the combined length of the threaded sleeve 8 and the threaded rod 9 can be adjusted, thereby controlling the length of the telescopic support.

[0026] A guide sleeve 11 is fixedly connected to one side of the intermediate block 1. A guide rod 12 is slidably connected inside the guide sleeve 11. One end of the guide rod 12 is fixedly connected to the hook 7. The hook 7 can be limited by the guide sleeve 11 and the guide rod 12, so that the hook 7 can move on both sides of the intermediate block 1 and control the distance between the hook 7 and the intermediate block 1.

[0027] like Figures 1-2 As shown, in some embodiments, a cylinder 2 is fixedly connected to the intermediate block 1, and the observation mark mounting sleeve 4 is slidably connected inside the cylinder 2, thereby adjusting the length of the end of the observation mark mounting sleeve 4 to adapt to the spacing between the reinforcing bars and the formwork.

[0028] A locking screw 3 is threaded onto the cylinder 2. By rotating the locking screw 3, the locking screw 3 and the observation mark mounting sleeve 4 are brought into contact, thereby locking the observation mark mounting sleeve 4 after the sliding is completed.

[0029] like Figures 1-2 and Figure 4 As shown, in some embodiments, the end of the observation mark mounting sleeve 4 is detachably fixedly connected to a protective cover 5 to reduce the phenomenon of debris entering the internal threaded hole of the protective cover 5.

[0030] The outer side of the end of the observation mark mounting sleeve 4 is provided with a threaded thread 6, and the protective cover 5 is threaded to the outer side of the threaded thread 6, thus making it relatively easy to install and remove the protective cover 5.

[0031] In some further embodiments, the protective cover 5 can be made of ceramic. After the protective cover 5 and the observation mark mounting sleeve 4 are bonded together with concrete, the protective cover 5 can be directly broken to complete the disassembly of the protective cover 5.

[0032] like Figures 1-3 and Figure 5 As shown, in some embodiments, a flux coating 13 may be fixedly connected to the inner side of the hook 7, and a welding core 15 is wrapped inside the flux coating 13. One end of the welding core 15 is fixedly connected to an electrode connector 14 extending to the outer side of the hook 7. The electrode connector 14 is used to connect to the welding gun.

[0033] The flux coating 13 is a multi-layer solid coating that wraps around the outside of the welding core 15. It is cylindrical and fits against the inside of the hook 7. The flux coating 13 is mainly composed of an arc stabilizer (such as potassium sodium compound), a slag-forming agent (silicon dioxide), and a gas-forming agent (starch). It decomposes when heated during welding, generating gas to isolate air. The molten slag covers the weld joint, preventing oxidation and promoting weld formation.

[0034] Electrode connector 14 is fused to the welding core 15 at one end and is a block-shaped conductor extending out of the hook claw 7 at the other end. It has a rectangular cross-section and is made of highly conductive copper alloy or aluminum alloy. It is used to connect the welding gun cable and conduct welding current to the welding core 15 to form an arc circuit.

[0035] The welding core 15 is a metal rod that penetrates the flux coating 13. One end of the welding core 15 is fixed to the electrode connector 14. The material of the welding core 15 can be low carbon steel (Q235) or stainless steel (304), depending on the material of the reinforcing bar. After the welding core 15 is energized, an electric arc is generated between it and the reinforcing bar. It melts itself as filler metal and forms a welded joint with the reinforcing bar.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
