Description

Technical Field

[0001] This utility model relates to the field of precast beam stress and strain monitoring technology, and more specifically, to a stress and strain monitoring device for precast beams in high-altitude and cold regions. Background Technology

[0002] When constructing engineering projects in high-altitude and cold regions, the problem of cracking in precast beams and slabs is particularly prominent. This is because the special climate and geographical conditions in these regions, such as low temperatures, large temperature differences, strong winds, and complex geological environments, have a significant impact on the performance of concrete structures, making beams and slabs more prone to cracking and affecting the safety and durability of the structure. In order to accurately monitor the stress and strain of key stress-bearing parts of the structure (such as stress concentration areas at the mid-span and supports of large-span beams) and typical locations, so as to promptly detect potential safety hazards and take corresponding measures, steel gauges are usually precisely embedded before concrete pouring. The steel gauges are generally fixed to the main reinforcement bars by binding or welding to ensure that they can deform in tandem with the concrete, thereby accurately reflecting the stress changes inside the structure. However, during actual construction, the lead wire of the rebar gauge is easily affected by the impact of concrete during the pouring process. Since the connection between the lead wire and the main body of the rebar gauge is relatively fragile, the connection can easily loosen under the impact of concrete. This loosening can interfere with the normal transmission of signals, leading to inaccurate or even lost monitoring data. Therefore, we have made improvements and proposed a stress-strain monitoring device for precast beams in high-altitude and cold regions. Utility Model Content

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-4 A stress-strain monitoring device for precast beams in high-altitude and cold regions includes a rebar gauge body 1, which is equipped with a rebar gauge lead wire 102. A reinforcement part is provided between the rebar gauge body 1 and the rebar gauge lead wire 102 to reinforce the connection between the rebar gauge body 1 and the rebar gauge lead wire 102. The reinforcement part includes a first sleeve 2 fixedly sleeved on the outer surface of the rebar gauge lead wire 102, with a first retaining ring 201 at both ends of the first sleeve 2. The reinforcement part also includes two arc-shaped clamping plates 302 disposed on the outer surface of the first sleeve 2, with connecting parts between the two arc-shaped clamping plates 302 and the rebar gauge body 1. The reinforcement part can reinforce the connection between the rebar gauge body 1 and the rebar gauge lead wire 102, reducing the possibility of the rebar gauge lead wire 102 loosening from the rebar gauge body 1 under concrete impact, thereby ensuring the stability and reliability of signal transmission.

[0020] The main body 1 of the rebar gauge and the lead wire 102 of the rebar gauge are both existing components that can be purchased directly from the market. Their specific structure, detection principle and circuit connection are all existing technologies, and will not be described in detail in this application.

[0021] Furthermore, the diameter of the first retaining ring 201 is larger than the diameter of the first sleeve 2. Both the first sleeve 2 and the first retaining ring 201 are fixed to the rebar gauge lead wire 102 by adhesive bonding. The length of the arc-shaped clamping plate 302 is adapted to the length of the first sleeve 2, and both sides of the arc-shaped clamping plate 302 are in contact with the two first retaining rings 201 respectively. The connector includes two arc-shaped connecting plates 3 connected to the rebar gauge body 1. One end of each of the two arc-shaped connecting plates 3 is connected to a protective plate 301. The arc-shaped clamping plate 302 is fixedly installed on the inner side of the protective plate 301. The arc-shaped connecting plate 3, the protective plate 301, the arc-shaped clamping plate 302 and the first retaining ring 201 cooperate with each other to limit the position of the first sleeve 2. Since the first sleeve 2 is fixed to the rebar gauge lead wire 102, the position of the rebar gauge lead wire 102 can be fixed, reducing the possibility of the rebar gauge lead wire 102 becoming loose from the rebar gauge body 1 under the impact of concrete.

[0022] Furthermore, the two arc-shaped connecting plates 3 are connected by bolts or welding; the arc-shaped connecting plate 3 is welded to the protective plate 301, and the protective plate 301 is welded to the arc-shaped clamping plate 302.

[0023] Furthermore, two protective plates 301 cover the connection between the main body 1 of the rebar gauge and the lead wire 102 of the rebar gauge. The shielding effect of the protective plates 301 can reduce the direct impact of concrete on the connection between the main body 1 of the rebar gauge and the lead wire 102 of the rebar gauge.

[0024] Furthermore, an auxiliary component is provided on the outer surface of the rebar gauge lead wire 102 for auxiliary fixing of the rebar gauge lead wire 102. The auxiliary component includes a second sleeve 4, which is fixedly sleeved on the outer surface of the rebar gauge lead wire 102. A second retaining ring 401 is fixedly connected to both sides of the second sleeve 4, and the diameter of the second retaining ring 401 is larger than the diameter of the second sleeve 4. The position of the second sleeve 4 is also close to the rebar gauge body 1. During installation, the second sleeve 4 can be tied to the rebar with tie wire to further fix the position of the rebar gauge lead wire 102. The second sleeve 4 is welded to the second retaining ring 401, and the second sleeve 4 and the rebar gauge lead wire 102 are fixed with glue. In this application, epoxy glue can be used as the glue.

[0025] Furthermore, both sides of the main body 1 of the rebar gauge are provided with rebar gauge connecting rods 101. When in use, the rebar gauge connecting rods 101 are tied together with the rebar by binding wire or directly welded to the rebar.
