Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a structure for detecting the heat of hydration of concrete. Background Technology

[0002] Concrete hydration testing is a technical means of assessing the hardening characteristics, structural safety, and construction quality of concrete by monitoring the heat generated during cement hydration (i.e., heat of hydration) and the resulting temperature changes. Its core purpose is to predict the risk of cracking in large-volume concrete due to temperature stress, verify the rationality of mix design, and guide curing processes.

[0003] Hole-type layered temperature measurement involves pre-installing or subsequently installing temperature measurement holes in concrete, inserting temperature sensors of adjustable depth (usually adjusted using threads) to achieve dynamic monitoring of hydration heat temperature at different depths within the same hole. The sensor depth is adjusted according to the hydration heat development stage (heating phase, cooling phase) to accurately capture temperature peaks at different locations.

[0004] The threaded adjustment of temperature sensor depth is slow, and since the required detection depth is usually deep, it takes a lot of time to adjust the sensor to the required position, which affects the detection efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where the detection depth is deep but the adjustment speed is slow, thus affecting the detection efficiency, and to propose a concrete hydration heat detection structure.

[0006] The technical solution of this utility model: a concrete hydration heat detection structure, applied to a concrete block, wherein a template is fixedly installed on the outer wall of the concrete block, comprising: The testing mechanism includes a positioning cylinder, which is fixedly installed on the inner wall of a concrete block. A straight rod is rotatably connected to the inner wall of the positioning cylinder. A threaded strip is slidably connected to the inner wall of the straight rod. The threaded strip slides radially along the straight rod. A threaded sleeve with a built-in thermal detection sensor is threadedly connected to the outer wall of the threaded strip. An adjusting rod is slidably connected inside the straight rod. The adjusting rod slides axially along the straight rod. A pressing block that contacts the threaded strip is fixedly installed on the outer wall of the adjusting rod. The adjustment rod is internally equipped with a depth marking mechanism.

[0007] Optionally, the end of the adjusting rod extends out from the heat insulation block, the inner wall of the threaded strip is provided with a wedge-shaped groove, and the shape of the extrusion block is the same as the shape of the wedge-shaped groove.

[0008] Optionally, a plurality of magnetic blocks for attracting threaded strips are fixedly installed in the middle of the adjusting rod, and the plurality of magnetic blocks are distributed at equal intervals in a straight line along the adjusting rod.

[0009] Optionally, a heat insulation block is fixedly installed at the end of the positioning cylinder, and the outer wall of the heat insulation block is rotatably connected to the positioning cylinder.

[0010] Optionally, the depth marking mechanism includes a pull rope located on the axis of the straight rod, with the other end of the pull rope fixedly connected to a threaded sleeve.

[0011] Optionally, a protective ring is fixedly installed inside the positioning cylinder. The protective ring is rotatably connected to the straight rod. The pull rope passes through the center of the protective ring. There is a gap between the protective ring and the pull rope. The two ends of the threaded strip are slidably connected to the protective ring and the heat insulation block, respectively.

[0012] Optionally, the outer wall of the threaded sleeve is fixedly fitted with a protrusion parallel to the straight rod, and the inner wall of the positioning cylinder is provided with a sliding groove, in which the protrusion slides.

[0013] Optionally, the outer wall of the protective ring is rotatably connected to a ball bearing, and the pull rope is attached to the outer wall of the ball bearing.

[0014] Optionally, an insulation sleeve is fixedly installed at the end of the positioning cylinder, the insulation sleeve wraps the pull rope, and the pull rope is engraved with a length mark.

[0015] Optionally, the inner wall of the concrete block is provided with five positioning cylinders, which are located at the four corners and the center of the concrete block, respectively.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: 1. This utility model, when the adjusting rod is pulled outward, causes the extrusion block to enter the wedge-shaped groove, and the extrusion block no longer extrudes the threaded strip. At the same time, under the magnetic force of the magnetic block, the threaded strip retracts into the straight rod, and the threaded strip no longer engages with the threaded sleeve. The position of the thermal detection sensor can be adjusted quickly by pulling the threaded sleeve with a pull rope, thereby improving the adjustment speed and thus improving the detection efficiency. Pushing the adjusting rod into the straight rod causes the threaded strip to extend and connect with the threaded sleeve, thereby fixing the position of the threaded sleeve and preventing vibration from causing changes in the position of the threaded sleeve, which would result in errors in the detection data.

[0017] 2. This utility model utilizes the scale markings on the pull rope to determine the depth of the threaded sleeve, which is also the depth of the thermal detection sensor. At the same time, it utilizes ball bearings so that the pull rope rests against the outer wall of the ball bearings during the pulling process, reducing friction and minimizing wear on the pull rope.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: This embodiment proposes a structure for detecting the heat of hydration in concrete, such as... Figure 1 As shown, it is applied to concrete block 1. A template 2 is fixedly installed on the outer wall of concrete block 1. Five detection mechanisms 3 are set inside the concrete block 1, located at the four corners and the center of the concrete block 1 respectively.

[0026] like Figure 2 and 3 As shown, the detection mechanism 3 includes a positioning cylinder 31, which is fixedly installed on the inner wall of the concrete block 1. A straight rod 33 is rotatably connected to the inner wall of the positioning cylinder 31, and a threaded strip 34 is slidably connected to the inner wall of the straight rod 33. The threaded strip 34 slides radially along the straight rod 33, and a threaded sleeve 35 with a built-in thermal detection sensor is threadedly connected to the outer wall of the threaded strip 34.

[0027] Rotating the straight rod 33 causes the threaded bar 34 to rotate, thereby allowing the threaded sleeve 35 to slide along the positioning cylinder 31. This adjusts the depth of the threaded sleeve 35, which in turn adjusts the depth of the thermal sensor. The threaded bar 34 and the threaded sleeve 35 are threadedly connected, fixing the position of the threaded sleeve 35 and preventing vibration from causing positional changes that could lead to errors in the detection data. A heat insulation block 32 is fixedly installed at the end of the positioning cylinder 31, and the outer wall of the heat insulation block 32 is rotatably connected to the positioning cylinder 31. The heat insulation block 32 prevents heat loss from the straight rod 33.

[0028] like Figure 4 As shown, an adjusting rod 36 is slidably connected inside the straight rod 33. The adjusting rod 36 slides along the axial direction of the straight rod 33. An extrusion block 37 that contacts the threaded strip 34 is fixedly installed on the outer wall of the adjusting rod 36. The end of the adjusting rod 36 extends out from the heat insulation block 32. A wedge-shaped groove is opened on the inner wall of the threaded strip 34. The shape of the extrusion block 37 is the same as the shape of the wedge-shaped groove.

[0029] By pushing the adjusting rod 36 into the concrete block 1, the adjusting rod 36 uses the pressing block 37 to press the threaded bar 34 against the threaded sleeve 35, so that the threaded sleeve 35 and the threaded bar 34 are engaged. At this time, rotating the adjusting rod 36 can change the depth of the threaded sleeve 35, that is, adjust the depth of the thermal detection sensor.

[0030] Multiple magnetic blocks 38 that attract threaded bars 34 are fixedly installed in the middle of the adjusting rod 36. The multiple magnetic blocks 38 are distributed in a straight line at equal intervals along the adjusting rod 36. When the adjusting rod 36 is pulled outward, the pressing block 37 enters the wedge-shaped groove. At the same time, under the magnetic force of the magnetic blocks 38, the threaded bars 34 are retracted into the straight rod 33 and no longer engage with the threaded sleeve 35.

[0031] In this embodiment, when the adjusting rod 36 is pulled outward, the squeezing block 37 enters the wedge-shaped groove, and the squeezing block 37 no longer squeezes the threaded strip 34. At the same time, under the magnetic force of the magnetic block 38, the threaded strip 34 is retracted into the straight rod 33, and the threaded strip 34 no longer engages with the threaded sleeve 35. This allows the threaded sleeve 35 to slide quickly in the positioning cylinder 31, improving the adjustment speed and thus improving the detection efficiency.

[0032] Example 2: Based on Example 1, this example proposes a structure for detecting the heat of hydration of concrete, such as... Figure 4 As shown, a depth marking mechanism 4 is installed inside the adjusting rod 36. The depth marking mechanism 4 includes a pull rope 41, which is located on the axis of the straight rod 33. The other end of the pull rope 41 is fixedly connected to the threaded sleeve 35. By pulling the pull rope 41, the threaded sleeve 35 can slide quickly inside the positioning cylinder 31. A heat insulation sleeve 5 is fixedly installed at the end of the positioning cylinder 31, which wraps around the pull rope 41. The pull rope 41 is engraved with length markings, and the depth of the threaded sleeve 35 can be determined according to the markings.

[0033] like Figure 5 As shown, a protective ring 42 is fixedly installed inside the positioning cylinder 31. The protective ring 42 is rotatably connected to the straight rod 33. The pull rope 41 passes through the center of the protective ring 42, and there is a gap between the protective ring 42 and the pull rope 41. The two ends of the threaded strip 34 are slidably connected to the protective ring 42 and the heat insulation block 32, respectively. The outer wall of the protective ring 42 is rolled with ball bearings 43. The pull rope 41 abuts against the outer wall of the ball bearings 43 to reduce friction and reduce wear on the pull rope 41.

[0034] The outer wall of the threaded sleeve 35 is fixedly fitted with a protrusion 44 parallel to the straight rod 33. The inner wall of the positioning cylinder 31 is provided with a sliding groove. The protrusion 44 slides in the sliding groove to prevent the threaded sleeve 35 from rotating with the straight rod 33 and thus preventing the depth from being adjusted.

[0035] In this embodiment, the depth of the threaded sleeve 35, i.e. the depth of the thermal detection sensor, can be determined by the scale markings on the pull rope 41. At the same time, the pull rope 41 is attached to the outer wall of the ball 43 during the pulling process, which reduces friction and reduces wear on the pull rope 41.

[0036] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
