Description

Technical Field

[0001] This utility model specifically relates to a mortar testing and shaping device. Background Technology

[0002] Mortar has a wide range of uses in construction engineering, mainly in the following aspects: using mortar as a bonding material to bind block materials together; plastering of interior and exterior walls, floors, beams, columns, ceilings and other components of buildings; tiling of marble, ceramic and other decorative panels; and joint connection of wall panels, concrete floor slabs and other components in prefabricated structures.

[0003] After the mortar is prepared, it needs to be placed into a mold for fixing and shaping. After the mortar is formed, it needs to be removed for testing. Existing testing and shaping devices have the following shortcomings: 1. Traditional testing and shaping devices are just simple forming molds and do not have temperature monitoring functions. If the temperature difference needs to be measured, multiple external devices need to be used to measure the inside and the surface separately. There are problems such as asynchronous time, equipment error, and mismatch of measuring points, which makes it difficult to truly reflect the internal and external temperature difference of the same specimen at a specific moment; 2. Even if an external temperature sensor is added, the center of the mortar layer is not known. Simply inserting the temperature sensor cannot guarantee that it is at the absolute center of the mortar layer. As a result, the "center temperature" measured by positional deviation is not representative, and the scientific validity of the data is greatly reduced. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mortar testing and shaping device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A mortar testing and shaping device includes a first shaping frame, a second shaping frame assembled with the first shaping frame, a first fixing screw located on one side of the first shaping frame and the second shaping frame, a second fixing screw located on the other side of the first shaping frame and the second shaping frame, a first temperature sensor installed on the first shaping frame for detecting the center temperature of the mortar, a support frame installed on the second shaping frame, and a second temperature sensor vertically mounted on the support frame for detecting the surface temperature of the mortar.

[0006] Preferably, the first lead screw sleeves are welded to both sides of the first shaping frame; Furthermore, a first bidirectional scale is welded to the inner side of the first shaping frame; Furthermore, a threaded screw hole for fixing the first temperature sensor is provided in the middle of the inner side of the first shaping frame, and the first bidirectional scale is located on one side of the threaded screw hole.

[0007] Preferably, the second shaping frame is welded with second lead screw sleeves on both sides; Furthermore, a second bidirectional scale is welded to the inner side of the second shaping frame.

[0008] Preferably, the first temperature sensor includes a sensing probe, a stud head integrally formed at the tip of the sensing probe, a leak-proof washer fitted on the sensing probe and tightly attached to the stud head, and a diaphragm sleeve fitted on the sensing probe.

[0009] Furthermore, the film sleeve is a PE film sleeve.

[0010] Preferably, the support frame includes a fixing plate bolted to the second shaping frame, a stud welded above the fixing plate, a first nut sleeve and a second nut sleeve screwed into the stud, and a support bar mounted on the stud and located between the first nut sleeve and the second nut sleeve.

[0011] The beneficial effects of this utility model are as follows: 1. The first and second bidirectional scales accurately guide the mortar laying thickness and uniformity. Operators can intuitively ensure that the center line of the mortar layer is aligned with the threaded screw hole, so that the screwed-in sensor probe is located in the exact center of the mortar layer, ensuring the accuracy and authority of the "center temperature" measurement. Moreover, the first and second temperature sensors work together to integrate the center temperature measurement and surface temperature measurement functions into one, with synchronized data acquisition time, recording the internal and external temperature difference of the internal heat conduction process, providing key data for the study of temperature stress and cracking risk. 2. The mechanical seal method using a stud head and a leak-proof washer achieves a reliable seal at the threaded hole, completely eliminating slurry leakage and ensuring the integrity of the specimen and the stability of the measurement point. In addition, the sensor probe is wrapped with a PE film sleeve, which acts as an isolation film. After curing, the sensor can be easily removed by simply tearing off the film, perfectly protecting the sensor and enabling it to be reused, thus greatly reducing the test cost. Attached Figure Description

[0012] Figure 1 This is a structural diagram of a mortar testing and shaping device according to the present invention; Figure 2 for Figure 1 The exploded diagram. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0014] Example like Figure 1-2As shown, a mortar testing and shaping device includes a first shaping frame 1, a second shaping frame 2 assembled with the first shaping frame 1, a first fixing screw 3 located on one side of the first shaping frame 1 and the second shaping frame 2, a second fixing screw 4 located on the other side of the first shaping frame 1 and the second shaping frame 2, a first temperature sensor 5 installed on the first shaping frame 1 for detecting the center temperature of the mortar, a support frame 6 installed on the second shaping frame 2, and a second temperature sensor 7 vertically assembled on the support frame 6 for detecting the surface temperature of the mortar.

[0015] Specifically, the temperature monitoring function is directly integrated into the shaping device itself, avoiding the problems of inaccurate positioning, easy displacement, and poor repeatability caused by the temporary placement of sensors in traditional methods. Moreover, through the fixed-position first temperature sensor 5 and second temperature sensor 7, the temperature data of the center and surface of the mortar test block can be collected synchronously and in real time.

[0016] The first shaping frame 1 has first lead screw sleeves 11 welded to both sides; a first bidirectional scale 12 welded to the inner side of the first shaping frame 1; and a through screw hole 13 for fixing the first temperature sensor 5 is also opened in the middle of the inner side of the first shaping frame 1, with the first bidirectional scale 12 located on one side of the through screw hole 13. The second shaping frame 2 has second lead screw sleeves 21 welded to both sides; and a second bidirectional scale 22 welded to the inner side of the second shaping frame 2. Specifically, when filling mortar, the operator can lay mortar layers of corresponding thickness according to the first bidirectional scale 12 and the second bidirectional scale 22, so that the first temperature sensor 5 is accurately positioned, ensuring the accuracy of the center temperature measurement.

[0017] It should be further explained that the first fixing screw 3 and the second fixing screw 4 cooperate to pass through the first screw sleeve 11 on both sides of the first shaping frame 1 and the second screw sleeve 21 on both sides of the second shaping frame 2, which can stabilize the assembly of the first shaping frame 1 and the second shaping frame 2, and also facilitate the disassembly of the first shaping frame 1 and the second shaping frame 2.

[0018] The first temperature sensor 5 includes a sensing probe 51, a stud head 52 integrally formed at the head end of the sensing probe 51, a leak-proof washer 53 fitted onto the sensing probe 51 and tightly against the stud head 52, and a diaphragm sleeve 54 fitted onto the sensing probe 51. Specifically, the sensing probe 51 passes through the mounting screw hole 13 and enters the first shaping frame 1, then the stud head 52 is screwed into the mounting screw hole 13, the leak-proof washer 53 is compressed to seal against leakage, and finally the diaphragm sleeve 54 is fitted onto the sensing probe 51.

[0019] The PE film sleeve 54 is specifically designed to prevent the mortar from sticking to the sensor probe 51 after it has cured. This prevents the sensor probe 51 from being affected during the assembly and disassembly of the first and second shaping frames 1 and 2, and also protects the sensor probe 51. In addition, the PE film sleeve is thin and does not affect the accuracy of the sensor probe 51 in real-time monitoring of the center temperature of the mortar layer.

[0020] The support frame 6 includes a fixing plate 61 bolted to the second shaping frame 2, a stud 62 welded to the top of the fixing plate 61, a first nut sleeve 63 and a second nut sleeve 64 screwed into the stud 62, and a support bar 65 mounted on the stud 62 and located between the first nut sleeve 63 and the second nut sleeve 64. Specifically, by rotating the first nut sleeve 63 and the second nut sleeve 64, the support bar 65 can be raised and lowered precisely and conveniently, thereby adjusting the height of the second temperature sensor 7 mounted on it. At this time, regardless of the height of the mortar surface, the second temperature sensor 7 can be adjusted to lightly touch the mortar surface, which is the optimal way to measure the surface temperature and ensures the accuracy of the surface temperature data. In addition, the locking structure formed by the first nut sleeve 63 and the second nut sleeve 64 can firmly lock the position of the support bar 65, preventing it from shifting due to vibration or other reasons during long-term monitoring and ensuring the stability of the data.

[0021] The first bidirectional scale 12 and the second bidirectional scale 22 are used to lay the mortar layer that needs to be shaped, so that the sensing probe 51 is always located in the center of the mortar layer. Then, the first nut sleeve 63 and the second nut sleeve 64 are adjusted, and the support bar 65 is raised and lowered so that the second temperature sensor 7, which is vertically fixed on the support bar 65, contacts the surface of the mortar layer. During the curing and shaping of the mortar layer, the first temperature sensor 5 continuously monitors the center temperature of the mortar layer, while the second temperature sensor 7 continuously monitors the surface temperature of the mortar layer, effectively displaying the internal and external temperature difference, thereby recording the morphological changes of the mortar layer during temperature changes.

[0022] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
