Description

Technical Field

[0001] This invention belongs to the field of testing technology for aluminoferrite cement mortar, and particularly relates to a device for observing the surface water loss rate of aluminoferrite cement mortar. Background Technology

[0002] During the early-age hydration process of aluminoferrite cement mortar, the surface water loss rate directly affects the quality of the hardened layer formation and the final mechanical properties. Currently, this field mainly uses flat plate molds for water loss observation, but it has the following three inherent drawbacks: 1. The boundary of the flat plate mold causes an abnormally accelerated water loss rate at the edge of the slurry, which cannot reflect the circumferential wind field environment of the real wall structure, and the measurement data has a systematic deviation from the actual working conditions; 2. The side wall obstruction of the traditional mold makes it difficult to observe the thickness of the hardened layer, requiring destructive sampling and testing (such as scraping), and cannot achieve in-situ real-time monitoring; 3. Existing equipment lacks a directional wind control module, and cannot study the influence of wind speed (0.5-3m / s) and wind direction (such as corner circulation) on the water loss rate.

[0003] The aforementioned limitations make it difficult for existing technologies to obtain water loss dynamics data of aluminoferrite mortar in real building structures (such as wall corners), thus hindering the optimization of material proportions. Therefore, there is an urgent need to develop a dedicated device that supports multi-angle observation and accurate wind field simulation. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a device for observing the surface water loss rate of aluminoferrite cement mortar. This device can simulate the circumferential wind field environment of a real cavity structure, making the measured data more realistic. At the same time, it can be directly observed from multiple points outside and the wind speed can be controlled, thereby further restoring the real environment and improving the authenticity of the data.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a device for observing the surface water loss rate of aluminoferrite cement mortar, comprising: The mold body is L-shaped and includes a vertical part and a horizontal part that are interconnected and transparent. A grouting port is provided on one side of the top of the vertical part, and the top of the horizontal part is designed as an opening. A blower, which is installed at the top of the vertical part and located on the side of the grouting port; An air guide shroud is connected to the outlet of a fan via a connecting part, and the air outlet of the air guide shroud extends above the horizontal part. A pull-out baffle, which is slidably disposed at the end of the horizontal part via a slot; A horizontal scale groove is engraved on the outer wall of the horizontal portion.

[0006] In the above technical solution, the L-shaped mold body can directly simulate the circumferential wind field environment of the corner, thereby eliminating the edge effect interference of traditional flat plate test mold. Furthermore, the combination of fan and wind guide hood provides adjustable directional wind, thereby accurately simulating wind speeds in different environments, thus more realistically reproducing the real scene and making the data more authentic. By using a transparent mold body with an opening design at the top of the horizontal part and a horizontal scale groove, the thickness of the hardened layer can be observed in real time, and the water loss time can be recorded.

[0007] Optionally, the lower edge of the horizontal part away from the pull-out baffle is provided with an arc-shaped bend, the radius of curvature of the arc-shaped bend R ≥ 10mm. The design of the arc-shaped bend can prevent the slurry from remaining at the corner, so that there is no dead corner accumulation when the high-pressure water gun is used for rinsing.

[0008] Optionally, the length of the air guide hood is adapted to the width of the horizontal section, and the air outlet axis of the air guide hood forms an angle of 30°-45° with the upper surface of the horizontal section. The 30°-45° tilt angle of the air outlet axis of the air guide hood can ensure that the airflow evenly covers the surface of the slurry in the horizontal section, thereby reducing the deviation of the local water loss rate.

[0009] Optionally, the inner wall of the horizontal part is made into a rough surface, the texture depth of the rough surface is 0.5-1mm, the spacing between adjacent textures is 2-3mm, the rough surface texture can significantly increase the adhesion of the slurry and prevent the hardened layer from slipping before measurement.

[0010] Optionally, the length of the horizontal section is ≥200mm to meet the requirement of a three-point measurement spacing of ≥50mm; the minimum graduation value of the horizontal scale groove is ≤0.5mm to improve the measurement resolution of the hardened layer thickness.

[0011] Optionally, the slot extends through the bottom of the horizontal section, and the through-type slot prevents slurry residue from clogging the slide rail.

[0012] Optionally, the slot includes a side wall slot on the side wall of the horizontal part and a bottom wall slot on the bottom wall of the horizontal part to enhance the guiding stability of the baffle. The length of the bottom wall slot is the same as the width of the horizontal part to ensure full coverage of the pull-out baffle and further avoid local slurry leakage during measurement. The inner wall of the side wall slot is provided with a sealing strip to block slurry leakage.

[0013] Optionally, the pull-out baffle has a groove on the side away from the horizontal part, and the groove provides a force fulcrum to facilitate manual pull-out operation.

[0014] Optionally, the top of the vertical section is provided with a detachable cover plate, and the fan and the air guide shroud are both fixed on the cover plate. The detachable cover plate integrates the fan and the air guide shroud, supporting quick cleaning / replacement of the air control components, thereby improving the long-term reliability of the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application uses an L-shaped mold body to directly simulate the circumferential wind field environment at the corner, thereby eliminating the edge effect interference of traditional flat plate molds. Furthermore, by using a combination of a fan and a wind guide hood to provide adjustable directional wind, it can accurately simulate wind speeds in different environments. By using a transparent mold body with an opening design at the top of the horizontal section and a horizontal scale groove, the thickness of the hardened layer can be observed in real time, and the water loss time can be recorded.

[0016] 2. The curved corner design of this application can prevent slurry residue at the corners, ensuring no dead corners are accumulated during high-pressure water jet rinsing.

[0017] 3. The rough texture of this application can significantly increase the adhesion of the slurry and prevent the hardened layer from slipping before measurement.

[0018] 4. The 30°-45° tilt angle of the air outlet axis of the air guide hood in this application can ensure that the airflow evenly covers the surface of the horizontal slurry, thereby reducing the deviation of local water loss rate. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 —2 As shown, the specific solution of the embodiment is as follows: A device for observing the surface water loss rate of aluminoferrite cement mortar includes: an L-shaped mold body 1, the mold body 1 includes a vertical part 12 and a horizontal part 11 that are interconnected and transparent, a grouting port 2 is provided on one side of the top of the vertical part 12, and the top of the horizontal part 11 is designed as an opening. In this embodiment, the mold body 1 is made of highly transparent tempered glass. Fan 3 is installed at the top of the vertical part 12 and located on the side of the grouting port 2; The air guide shroud 4 is connected to the outlet of the fan 3 via the connecting part 41, and the air outlet of the air guide shroud 4 extends above the horizontal part 11. A pull-out baffle 5 is slidably disposed at the end of the horizontal part 11 via a slot 112; Horizontal scale groove 8 is engraved on the outer wall of the horizontal part 11.

[0024] In this embodiment, the L-shaped mold body 1 can directly simulate the circumferential wind field environment at the corner, thereby eliminating the edge effect interference of traditional flat plate molds. Furthermore, the combination of the fan 3 and the wind guide hood 4 provides adjustable directional wind, thereby accurately simulating wind speeds in different environments, thus more realistically reproducing the real scene and making the data more authentic. By using the transparent mold body 1 with the top opening design and horizontal scale groove 8 of the horizontal part 11, the thickness of the hardened layer can be observed in real time, and the water loss time can be recorded.

[0025] In this embodiment, the top of the vertical part 12 is provided with a detachable cover plate. The fan 3 and the air guide 4 are both fixed on the cover plate. The detachable cover plate integrates the fan 3 and the air guide 4, which supports quick cleaning / replacement of the air control components, thereby improving the long-term reliability of the equipment.

[0026] like Figure 3 As shown, the lower edge of the horizontal part 11 away from the pull-out baffle 5 is provided with an arc-shaped bend 111. The radius of curvature R of the arc-shaped bend 111 is greater than or equal to 10 mm. The design of the arc-shaped bend 111 can prevent the slurry from remaining at the corner, so that there is no dead corner accumulation when the high-pressure water gun is used for rinsing.

[0027] In this embodiment, the length of the air guide shroud 4 is adapted to the width of the horizontal part 11, and the air outlet axis of the air guide shroud 4 forms an angle of 30°-45° with the upper surface of the horizontal part 11. The design of the air outlet axis of the air guide shroud 4 at an angle of 30°-45° can ensure that the airflow evenly covers the surface of the slurry in the horizontal part 11, thereby reducing the deviation of the local water loss rate.

[0028] like Figure 2 As shown, the inner wall of the horizontal part 11 is set as a rough surface 7. The texture depth of the rough surface 7 is 0.5-1mm, and the spacing between adjacent textures is 2-3mm. The texture of the rough surface 7 can significantly increase the adhesion of the slurry and prevent the hardened layer from slipping before measurement.

[0029] It should be noted that in this embodiment, the length of the horizontal part 11 is ≥200mm to meet the requirement of a three-point measurement spacing of ≥50mm; the minimum graduation value of the horizontal scale groove 8 is ≤0.5mm to improve the measurement resolution of the hardened layer thickness.

[0030] like Figure 3-4 As shown, the slot 112 extends through the bottom of the horizontal section 11, and the through-type slot 112 prevents slurry residue from clogging the slide rail. In addition, the slot 112 includes a side wall slot provided on the side wall of the horizontal section 11 and a bottom wall slot provided on the bottom wall of the horizontal section 11, thereby enhancing the guiding stability of the baffle. The length of the bottom wall slot is the same as the width of the horizontal section 11, ensuring that the pull-out baffle 5 covers the entire range, further preventing local slurry leakage during measurement. The inner wall of the side wall slot is provided with a sealing strip, which blocks slurry leakage.

[0031] In this embodiment, a cleaning groove 113 communicating with the side wall groove is opened on the side wall at the end of the horizontal part 11. The depth of the cleaning groove 113 is the same as the depth of the side wall groove, and it is located at the lower end of the side wall of the horizontal part 11 and connected to the bottom wall groove. This design facilitates the cleaning of cement slurry remaining in the side wall groove in the later stage.

[0032] like Figure 1 As shown, a groove 51 is provided on the side of the pull-out baffle 5 away from the horizontal part 11. The groove 51 of the baffle provides a fulcrum for applying force, which facilitates manual pull-out operation.

[0033] The working principle of the above embodiment is as follows: First, ferroaluminate cement mortar is injected into the vertical part 12 through the grouting port 2. Grouting is stopped after the mortar fills the horizontal part 11 of the L-shaped channel. After the fan 3 is started, the airflow passes through the air guide hood 4 and evenly covers the surface of the mortar in the horizontal part 11 at an angle of 30°-45° to simulate the circumferential wind field environment at the corner of the wall. The hardening process of the mortar is observed in real time through the transparent wall, and the water loss time is recorded through the horizontal scale groove 8. After the water loss is completed, the pull-out baffle 5 is moved out along the through slot 112 to allow the mortar to flow out and expose the residual hardened layer. The thickness of the hardened layer is measured by the three-point method with the horizontal scale groove 8 as the reference and the average value is taken. Finally, the channel is flushed by a high-pressure water gun. The arc-shaped bend 111 and the through slot 112 are designed to ensure that there is no residual mortar accumulation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
