Description

Technical Field

[0001] This utility model relates to the field of engineering concrete strength testing technology, and in particular to a test mold installation platform for concrete core sample processing. Background Technology

[0002] The strength of concrete affects the safety, durability, and economy of structures. For concrete with long pouring time and surface weathering, core sampling is a preferred method in the testing industry. Whether the concrete core samples meet the standard requirements is a necessary step in the testing process.

[0003] In existing core sample processing, the diameter of the actual core sample specimen is not very uniform during drilling, which will affect the accuracy of fixing during processing: In the existing technology, multiple cylindrical core sample specimens are arranged close together in parallel and pressed together from above and below by clamping plates. However, due to the slight difference in diameter of each core sample specimen, some core samples in the middle section or at the corner of the entire array of core sample specimens cannot be fixed, and loosening and displacement will occur during cutting.

[0004] The flatness and perpendicularity of the cut core sample do not meet the standards, and the blade is prone to deviating during high-speed cutting. As a result, the dimensions of the processed core sample do not meet the test standards, and it is necessary to drill and process the core sample again at the engineering site, which is very troublesome. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a test mold installation platform for concrete core sample processing in order to overcome the shortcomings of the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a test mold installation platform for concrete core sample processing, including an operating platform with a cutting machine installed, a clamping plate device provided on the operating platform, a number of test piece stations arranged in a straight line on the upper surface of the operating platform, a test mold assembly placed on the test piece station, and the test mold assembly being clamped back and forth by the clamping plate device before cutting.

[0007] The test mold assembly includes a rectangular test mold with a through hole in the center. A core sample is placed in the through hole, and a cement slurry bonding layer is provided between the outer wall of the core sample and the inner wall of the test mold.

[0008] By adopting the above technical solution, cement grout is injected into the gap between the core sample and the mold, so that the whole is formed into a solid connection that is not easy to loosen.

[0009] The bottom of the operating platform is slidably connected to a demolding device via a track, and the upper end of the operating platform is connected to a cement grouting device via a back frame plate.

[0010] By adopting the above technical solution, the demolding device is integrated into the bottom of the operating platform, which facilitates timely demolding operations at the corresponding workstations, allows for rapid movement, simple docking, and improved efficiency; at the same time, the cement slurry injection device is integrated into the top of the operating platform, which facilitates operation and improves work efficiency.

[0011] Furthermore, the demolding device of this utility model is provided with a push rod at the top center and lifting columns at the four corners of the top; the test piece station is provided with holes for the push rod and lifting columns to extend out.

[0012] By adopting the above technical solution, when demolding is required after cutting, simply extend the lifting column of the demolding device at the lower end of the corresponding workstation beyond the mold assembly, fix the mold with the top hole locking plate, and start the top push rod to push out the remaining core sample to complete the demolding.

[0013] Furthermore, the inner wall of the mold described in this utility model is coated with a butter coating to facilitate demolding of the processed core sample.

[0014] Furthermore, the cement grouting device of this utility model includes a grouting machine, a coiler, and a grouting gun, which are connected by a pipeline.

[0015] The beneficial effects of this utility model are as follows: The test mold installation platform for concrete core sample processing provided by this utility model solves the problems existing in the prior art. By using the core sample test mold and clamping mechanism on the operating platform, each core sample can be completely fixed even if there are differences in diameter, ensuring the verticality and flatness of the cut. At the same time, this utility model also integrates a demolding device and a cement grouting device on the operating platform, which is convenient to operate and can greatly improve work efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0022] like Figures 1-3 The above describes a test mold installation platform for concrete core sample processing, which includes an operating platform 1 equipped with a cutting machine, a clamping plate device 2 on the operating platform 1, and several test piece stations arranged in a straight line on the upper surface of the operating platform 1. Test mold components are placed on the test piece stations and are clamped by the clamping plate device 2 before cutting.

[0023] The test mold assembly includes a rectangular test mold 3, with a through hole 4 in the center of the test mold 3. A core sample 5 is placed in the through hole 4, and a cement grout bonding layer 6 is provided between the outer wall of the core sample 5 and the inner wall of the test mold 3.

[0024] The bottom of the operating platform 1 is slidably connected to the demolding device 8 via the track 7, and the upper end of the operating platform 1 is connected to the cement grouting device via the back frame plate 9.

[0025] The demolding device 8 has a push rod 10 at the top center and lifting columns 11 at the four corners of the top; the test piece station has holes for the push rod 10 and lifting columns 11 to extend out. The inner wall of the test mold 3 is coated with a grease coating 12.

[0026] The cement grouting device includes a grouting machine 13, a coiler 14, and a grouting gun 15, which are connected by pipes.

[0027] Working principle:

[0028] Based on the actual situation, a certain number of test molds are placed one by one on each specimen station of the operating platform and clamped at the front and back by clamping plates. Since the test molds are rectangular in shape with uniform dimensions, arranging them in a row ensures that each test mold is completely clamped and fixed. The drilled core specimen is placed in the test mold, with the upper part of the core specimen extending above the test mold. The inner wall of the test mold is coated with grease, and cement grout is injected into the gap between the inner wall of the test mold and the core specimen to strengthen the connection. Then, the protruding part of the core specimen is cut using cutting equipment. Under this new installation structure, the surface of the core specimen after cutting is flat, and the height-to-diameter ratio and perpendicularity meet the appearance dimensional requirements of JGJ / T384-2016.

[0029] Demolding operation after processing: Move the demolding device at the bottom of the operating platform to the corresponding station, extend the lifting column of the demolding device at the lower end of the corresponding station from the corresponding hole to above the test mold assembly, and use the locking plate with holes at the top to fix the test mold on the platform. Start the push rod to push out the remaining core sample to complete the demolding.
