Description

Technical Field

[0001] This utility model relates to the technical field of low-temperature concrete test chambers, specifically to a concrete load-bearing structure for a low-temperature concrete test chamber. Background Technology

[0002] A low-temperature concrete test chamber is a testing device specifically designed to simulate low-temperature environments for the low-temperature treatment and performance testing of concrete specimens. It controls the temperature and humidity of the concrete specimens to maintain them under certain low-temperature conditions, thereby fully utilizing their strength, durability, and frost resistance. At the same time, the hydration reaction rate of concrete slows down under low-temperature conditions, but appropriate low-temperature treatment can shorten the curing period and accelerate the development of concrete strength. The load-bearing structure in the low-temperature test chamber is used to place the concrete specimens, which helps to conduct low-temperature treatment and performance testing on the concrete specimens.

[0003] Currently, the load-bearing structure in low-temperature test chambers lacks a pull-out structure and does not have a function to guide its movement, resulting in poor practicality of the load-bearing structure. To address this, we propose a concrete load-bearing structure for concrete low-temperature test chambers. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a concrete load-bearing structure for a low-temperature concrete test chamber. This new load-bearing structure has a pull-out structure and a guiding function for the movement of the load-bearing structure, thereby improving the practicality of the load-bearing structure.

[0006] Sliding components are provided on both sides of the bottom end of the concrete bearing slab. The sliding components include a pulley, a first support plate, and a second support plate. The bottom of the pulley is located inside the sliding groove. The first support plate and the second support plate are located on both sides of the pulley. The tops of the first support plate and the second support plate are connected to the bottom of the concrete bearing slab.

[0007] By adopting the above technical solution, after the low temperature test is completed, the personnel can pull the concrete bearing plate out of the test chamber by firmly gripping the groove. During the movement of the concrete bearing plate, the bottom of the pulley is located inside the groove, which can guide and limit the movement of the pulley, so that the movement of the pulley is smooth. The first support plate and the second support plate can support the pulley at the same time, and the bearing enables the pulley to rotate smoothly.

[0008] Specifically, the sliding assembly also includes bearings and bearing mounting grooves. Both ends of the pulley are connected to the first support plate and the second support plate respectively through bearings. The first support plate and the second support plate are both provided with bearing mounting grooves inside.

[0009] By adopting the above technical solution, the No. 1 support plate and the No. 2 support plate can support the pulley, the bearing enables the pulley to rotate smoothly, and the bearing mounting groove facilitates the installation of the bearing.

[0010] Specifically, mounting slots are provided on both sides of the interior of the test chamber at the upper ends of the first and second slides.

[0011] By adopting the above technical solution, the installation groove facilitates the installation of the concrete bearing plate, allowing the concrete bearing plate to be stably positioned inside the test chamber.

[0012] Specifically, the concrete bearing slab has a groove inside, and the bottom of the groove has uniformly formed mesh holes.

[0013] Specifically, the concrete support plate is made of stainless steel.
