Description

Technical Field

[0001] This utility model belongs to the field of mortar curing technology, and specifically relates to a standard curing box for mixed mortar specimens. Background Art

[0002] Mixed mortar is a building material made by mixing cement, sand, water, and other possible ingredients in a certain proportion. It is widely used in masonry, plastering, and repair of building structures. To evaluate the quality of mixed mortar and its performance in practical applications, standardized tests are required on mortar specimens. These tests include, but are not limited to, compressive strength, flexural strength, and bond strength, and the accuracy of the test results largely depends on the specimen preparation and curing process.

[0003] The standard curing chamber for mixed mortar specimens is an integrated new type of curing device that integrates functions such as humidity control, temperature control, air circulation, and remote monitoring. Its interior is divided into several spaces by partitions. In order to ensure uniform temperature and humidity in all parts of the chamber, the partitions are generally designed with a hollow structure to connect the spaces. However, since mortar specimens inevitably shed slag during curing, the slag will pass through the partitions and interfere with other spaces. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a standard curing box for mixed mortar specimens. The specific technical solution is as follows:

[0005] A standard curing chamber for mixed mortar specimens includes a chamber body, in which partitions are horizontally arranged. The partitions are of a double-layer structure, including an upper partition and a lower partition connected below the upper partition. The upper partition has a first channel, and the lower partition has a second channel. The first and second channels are staggered and can cooperate with each other to form a flow path that allows gas to flow.

[0006] As a further technical solution of this utility model, the lower partition also has an interceptor corresponding to the first channel, the interceptor opening towards the end face of the first channel and forming a temporary storage space.

[0007] As a further technical solution of this utility model, the partition is slidably arranged in the box.

[0008] As a further technical solution of this utility model, a suspension assembly is provided above the partition, the suspension assembly is slidably arranged in the box and slides in or out with the pull of the partition; the suspension assembly includes a sliding rod slidably arranged in the box and a suspension member connecting the sliding rod and the partition.

[0009] As a further technical solution of this utility model, the distance between the slide rod and the spacer gradually increases along the sliding direction, and the suspension member is an elastic component.

[0010] The beneficial effects of the utility model are as follows:

[0011] (1) In this application, the partition is set as a double-layer structure. Even if the test block falls through the channel, it will fall directly onto the surface of the lower partition and be intercepted. This can prevent the slag from falling from the test block from flowing between the various curing chambers. At the same time, the channel one and the channel two are still connected, which can form a flow path for gas to flow, so that the gas can flow between the various curing chambers and ensure the uniformity of temperature and humidity.

[0012] (2) In this application, a suspension assembly is provided, which can apply an upward traction force to the free end of the spacer when the spacer slides out, thereby ensuring that the free end of the spacer does not droop and avoiding bending of the spacer as a whole.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Figure 1 A schematic diagram of the overall structure of the standard curing box for mixed mortar specimens is shown. Figure 1The standard curing box for mixed mortar specimens includes a box body 100, with a curing space 110 inside the box body 100. One end of the curing space 110 is open to allow specimens to be placed or removed. Dividers 200 are horizontally arranged within the curing space 110, and several sets of dividers 200 are provided to divide the curing space 110 into several curing chambers 120. Each curing chamber 120 is interconnected to achieve uniform curing. The open end of the curing space 110 has an outwardly flared stepped portion 130. In actual use, a door is installed at this location to open or close the curing space 110. It should be noted that the above are all prior art and are not within the scope of protection of this application.

[0021] Figure 2 A structural schematic diagram of the spacer 200 and the suspension assembly 300 is shown; Figure 2 In the middle, the spacer 200 is slidably arranged in the curing space 110, and can slide out when the specimen is placed or removed for easy placement, and can slide back into the curing space 110 for easy curing after the specimen is placed; the specific sliding method is not limited in this application, for example, as Figure 1 As shown, the side wall of the curing space 110 is provided with a side slide rail corresponding to the partition 200, and the side rib of the partition 200 extends horizontally and slides in the side slide rail. When the partition 200 is driven by an external force, it can slide in the side slide rail. The box 100 is also provided with a suspension assembly 300, which is connected to the side of the partition 200 facing the opening end of the curing space 110. It is used to support the free end of the partition 200 when the partition 200 slides out, so as to prevent the free end of the partition 200 from being compressed by the test piece and causing the partition 200 to bend as a whole.

[0022] Figure 3 A schematic diagram of the structure of the spacer 200 is shown; Figure 3In the middle, the partition 200 has a double-layer structure, including an upper partition 210 and a lower partition 220 connected below the upper partition 210. The upper partition 210 has a first channel 211, and the lower partition 220 has a second channel 221. The first channel 211 and the second channel 221 are staggered and can cooperate with each other to form a flow path that allows gas to flow. The staggered arrangement here means that the first channel 211 and the second channel 221 do not overlap on the horizontal projection plane. The upper partition 210 directly carries the test block. When the test block falls through the first channel 211, it will fall directly onto the surface of the lower partition 220 and be intercepted. This can prevent the falling slag from flowing between the various curing chambers 120, which is convenient for recording the falling weight. At the same time, the first channel 211... The connection between channel 211 and channel 221 remains, forming a flow path for gas circulation, allowing gas to circulate between each curing chamber 120 and ensuring uniformity of temperature and humidity. The lower partition 220 also has an interceptor 222 corresponding to channel 1 211. The interceptor 222 opens towards the end face of channel 1 211 and forms a temporary storage space. Here, "corresponding" means that the number and position of channel 1 211 and interceptor 222 are corresponding. That is, an interceptor 222 installed on the lower partition 220 is provided directly below each channel 1 211. Fallen slag will be directly collected in the temporary storage space of the interceptor 222 to prevent the slag from rolling along the surface of the lower partition 220.

[0023] Figure 4 A schematic diagram of the suspension assembly 300 is shown. Figure 4 In the middle, a suspension assembly 300 is provided above the partition 200. The suspension assembly 300 includes a slide rod 310 slidably arranged in the housing 100 and a suspension member 320 connecting the slide rod 310 and the partition 200. Two sets of suspension assemblies 300 are provided, arranged on both sides above the partition 200. One end of the suspension member 320 is connected to the free end of the slide rod 310, and the other end is connected to the free end of the partition 200, so that when the partition 200 is pulled out, it can drive the slide rod 310 to slide out synchronously. At this time, the suspension member 320 connects the slide rod 310 and the partition 200. Between 0 and 0, the free end of the spacer 200 can be suspended to prevent the spacer 200 from bending; the distance between the slide rod 310 and the spacer 200 gradually increases along the sliding direction, and the suspension member 320 is an elastic component; the slide rod 310 is set at an angle. Since the spacer 200 is pulled out smoothly, while the slide rod 310 is pulled out at an upward angle, as the distance pulled out increases, the height difference between the slide rod 310 and the spacer 200 gradually increases. The suspension member 320 is stretched and applies an upward traction force to the spacer 200, thereby ensuring that the free end of the spacer 200 does not droop.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
