Description

Technical Field

[0001] This utility model relates to the field of concrete test block curing technology, and in particular to a concrete test block curing box. Background Technology

[0002] The compressive strength of concrete is a key parameter for measuring its load-bearing capacity. By preparing concrete test blocks, curing them under standard conditions to the specified age, and then conducting compressive strength tests, the rationality of the concrete mix design and construction quality can be directly reflected. The curing of concrete test blocks requires the use of a concrete test block curing chamber.

[0003] Current technology for curing concrete test blocks involves using a closed curing chamber with controlled temperature and humidity for periodic curing. However, the water mist generated by the atomizer is delivered into the curing chamber, but the outlet position of the water mist is fixed. Contact between the concrete test block and the water mist can only occur after the water mist has diffused within the chamber. This limited diffusion of the water mist and the potential for significant differences in curing conditions between different layers of concrete test blocks make this problem more likely. Utility Model Content

The diffusion of water mist is limited, and the curing conditions of concrete test blocks at different layers are prone to be very different.

[0005] This utility model provides a concrete test block curing box, comprising:

[0006] The curing chamber includes a curing chamber and an installation chamber. An atomizer is installed in the installation chamber. Several evenly distributed atomizing air outlet connectors are fixedly connected to the rear side of the curing chamber. A test block support is also included, with several evenly distributed support components inside the curing chamber. Each support component includes a frame and a support tube. A conveying cavity is opened inside the frame, and the support tubes are evenly distributed inside the frame. Several evenly distributed air outlet holes are opened on the surface of the support tubes, through which the water mist generated by the atomizer is sprayed out. Finally, an atomizing conveying connector includes a connecting tube located on the rear side of the frame for use with the atomizing air outlet connectors.

[0007] Optionally, the two ends of the support tube are rotatably connected to the inner sides of the frame, the conveying cavity is connected to the inside of the support tube, and the rotation of the support tube is used to adjust the spray direction of the water mist.

[0008] Optionally, one side of the support tube is an arc surface, and the other side of the support tube is a flat surface, with the air outlet located on the arc surface of the support tube.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] As mentioned earlier, the outlet position of the water mist in the current curing chamber is fixed. The concrete test block in the curing chamber can only come into contact with the water mist after the water mist has diffused in the curing chamber. The diffusion of water mist is limited, and it is easy for the curing conditions of concrete test blocks at different layers to be significantly different.

[0027] To address this issue, the present invention provides a concrete test block curing box, which uses the test block support 2 holding the concrete test blocks as the spray point for water mist inside the curing chamber 101. The water mist is sprayed outward through several air outlets 204 on the support pipe 202. The water mist can be sprayed layer by layer according to the arrangement of the concrete test blocks, increasing the dispersion of the sprayed water mist inside the curing chamber 101 and increasing the uniformity of humidification of the concrete test blocks inside the curing box.

[0028] The following is combined Figures 1-7 This utility model is described in detail.

[0029] Example 1 Figures 1-7 As shown, this utility model provides a raw material mixing tank, especially a concrete test block curing box, including a curing box body 1, a test block support 2, an atomizing conveying docking part 3, and an atomizing air outlet 4.

[0030] The curing chamber 1 is internally divided into a curing chamber 101 and an installation chamber 102. The curing chamber 101 holds concrete test blocks, which are then periodically cured through humidity and temperature regulation. The installation chamber 102 houses a mist atomizer 103, which atomizes water and, in conjunction with a pump built into the curing chamber, delivers the water mist into the curing chamber 101. The inner wall of the curing chamber 1 is decorated with... Figure 5 As shown, a connecting cavity 5 is provided, through which the water mist generated by the atomizer 103 is transported towards the curing chamber 101. Several evenly distributed atomizing air outlet connectors 4 are fixedly connected to the rear inner wall of the curing chamber 101. The atomizing air outlet connectors 4 and the connecting cavity 5 are connected together, and the water mist can be sprayed out into the interior of the curing chamber 101 through the atomizing air outlet connectors 4.

[0031] Several test block support members 2 are evenly distributed inside the curing chamber 101. Each test block support member 2 includes a frame 201 and a support tube 202. Mounting guide rail grooves 6 are provided on both outer sides of the frame 201, and snap-fit ​​guide rails 7 are fixedly connected to the inner side walls of the curing chamber 101. The frame 201 can slide and be snapped into place inside the curing chamber 101 via the mounting guide rail grooves 6 and the snap-fit ​​guide rails 7 to install the test block support members 2. The frame 201 has a conveying chamber 203 inside, and several evenly distributed support tubes 202 are set inside the frame 201. One side of the support tube 202 is curved, and the other side is flat. Several evenly distributed air outlets 204 are set on the outer side of the support tube 202. A connecting tube 301 is fixedly connected to the rear side of the frame 201. After the frame 201 is completely installed inside the curing chamber 101, the connecting tube 301 on the rear side of the frame 201 can be completely inserted into the atomizing air outlet 4. The water mist input into the connecting channel 5 can directly enter the conveying chamber 203 inside the frame 201, and after passing through the support tubes 202, it is sprayed out from the air outlets 204, increasing the dispersion of the water mist spray position inside the curing chamber 101. In this way, the concrete specimens stacked inside the curing chamber 101 can be sprayed with water mist from the upper layer of specimen support 2, which increases the homogenization speed of the water mist and reduces the phenomenon that some concrete specimens inside the curing chamber 101 are hindered from contacting the water mist for wetting due to the stacked concrete.

[0032] Through such Figures 1-2 The touch panel on the front of the curing chamber body 1 is shown to set the relative temperature and relative humidity parameters inside the curing chamber 101. The test block support 2 is connected to the snap-fit ​​guide rail 7 through the mounting guide rail groove 6 of the frame 201, ensuring that the connecting pipe 301 on the rear side of the frame 201 is fully inserted into the interior of the atomizing air outlet connector 4. Figure 4 and Figure 7As shown, several evenly distributed auxiliary ventilation holes 302 are also provided on the surface of the connecting tube 301. When the connecting tube 301 is fully inserted into the atomizing air outlet connector 4, the auxiliary ventilation holes 302 are also inside the atomizing air outlet connector 4. The auxiliary ventilation holes 302 will not be blocked. If the tail end of the connecting tube 301 is blocked, the atomizing air outlet connector 4 can still enter the conveying cavity 203 inside the frame 201 through the auxiliary ventilation holes 302.

[0033] Concrete test blocks are placed on test block support 2. The flat side of the support tube 202 of test block support 2 is used to place square concrete test blocks, and the curved side of the support tube 202 is used to place cylindrical concrete test specimens. When placing square concrete test specimens, the flat side of the support tube 202 of test block support 2 is facing upwards, and when placing cylindrical concrete test specimens, the curved side of the support tube 202 is facing upwards. Cylindrical concrete test specimens can be horizontally clamped between the support tubes 202 without blocking the vent 204.

[0034] In Example 2, both ends of the support tube 202 are rotatably connected to the two sides inside the frame 201. The connection points between the support tube 202 and the frame 201 are sealed. The direction of the water mist spray is adjusted by rotating the support tube 202 inside the frame 201. Simultaneously, where the test block support 2 is not engaged at certain locations, the corresponding atomizing air outlet 4 can directly spray water mist into the curing chamber 101. A temperature regulating component 8 is installed at the bottom of the curing chamber 101, which, in conjunction with the touch panel on the front surface of the curing chamber body 1, regulates the temperature and humidity inside the curing chamber 101.

[0035] Alternatively, the concrete specimen can be placed without placing it on the topmost specimen support 2, and then layer by layer from the second layer downwards. Each specimen support 2 has its support tube 202 with the arc surface facing down and snapped onto the frame 201. The air outlet 204 on the surface of the support tube 202 is aligned with the concrete specimen with the air outlet facing down. The atomizer 103 is then activated. The atomizer 103 atomizes the water and delivers it through the connecting cavity 5 to the atomizing air outlet 4. After passing through the inside of the delivery cavity 203, the water is sprayed out from the air outlet 204 and diffuses inside the curing chamber 101, increasing the direct contact between the water mist and the concrete specimen inside the curing chamber 101.

[0036] In summary, this utility model uses the concrete specimen support 2, which holds the concrete specimens, as the spray point for water mist inside the curing chamber 101. The water mist is sprayed outward through several air outlets 204 on the support pipe 202. The water mist can be sprayed layer by layer according to the arrangement of the concrete specimens, which increases the dispersion of the sprayed water mist inside the curing chamber 101 and increases the uniformity of humidification of the concrete specimens in the curing chamber.
