Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a testing tool for low-density ultra-lightweight foamed concrete. Background Technology

[0002] Foamed concrete is a new type of lightweight thermal insulation material containing a large number of closed pores. It is produced by mechanically foaming a foaming agent using the foaming system of a foaming machine, uniformly mixing the foam with cement slurry, and then pouring it on-site or molding it using the pumping system of the foaming machine. After natural curing, it is formed.

[0003] Although foamed concrete is not used in load-bearing components of buildings, its strength still needs to meet certain requirements. The produced foamed concrete also needs to undergo strength testing to ensure its compliance. Existing testing tools often simply support the foamed concrete sample with a pad before applying external force. However, in actual use, foamed concrete is not necessarily in a state of complete overall support; it may be used in partially supported areas. Therefore, testing only with the sample fully supported by a pad results in incomplete strength testing and significant limitations. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a low-density ultralight foamed concrete testing tool that addresses the above-mentioned technical deficiencies. This tool can change the form of support for foamed concrete samples and improve the comprehensiveness of strength testing.

[0005] The technical solution adopted by this utility model is as follows: a low-density ultralight foamed concrete testing tool is provided, including a press and a base; a support frame is fixed on the base; the top of the support frame is connected to the outer shell of the press; the lower pressing end of the press is vertically downward and a pressure plate is fixed thereon; the pressure plate is correspondingly parallel to the base above; an installation groove is opened on the base; a support component for adjusting the support range of the foamed concrete sample is provided in the installation groove. The support assembly includes a tray that is inserted into the mounting slot; the bottom of the tray has multiple slots evenly distributed in a grid pattern; support blocks are inserted into the slots respectively; the upper end of the support block is higher than the upper end of the tray.

[0006] To further optimize this technical solution, the radial cross-section of the support block of a low-density ultralight foamed concrete testing tool is square; the lower side length of the support block is smaller than the upper side length; and the upper ends of adjacent support blocks are in contact with each other.

[0007] To further optimize this technical solution, an electromagnetic chuck is embedded inside the tray of a low-density ultralight foamed concrete testing tool; the bottom of each slot is positioned above the electromagnetic chuck; and the support block magnetically attaches to the electromagnetic chuck.

[0008] To further optimize this technical solution, a tray of a low-density ultralight foamed concrete testing tool is connected to a bracket on one side; a magnetic rod is correspondingly snapped onto the bracket; the magnetic rod is magnetically attracted to the top of the support block.

[0009] The beneficial effects of this utility model are as follows: The press, driven by a pressure plate, applies pressure to the foamed concrete sample placed on the support assembly. The applied pressure can be adjusted as needed to meet the requirements of strength testing. The bottom of the tray has multiple evenly distributed slots arranged in a grid pattern, each containing a corresponding support block. The upper end of the support block is higher than the top of the tray. By installing and removing the support blocks, the range and form of support for the foamed concrete sample can be changed, allowing for more comprehensive strength testing and better adaptation to the support methods used in actual construction. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 A top-view structural diagram of the support assembly; Figure 3 This is a schematic diagram of the structure of the slot inside the support assembly.

[0011] In the diagram, 1 is the press; 2 is the base; 3 is the support frame; 4 is the pressure plate; 5 is the mounting groove; 6 is the tray; 7 is the slot; 8 is the support block; 9 is the electromagnetic chuck; 10 is the bracket; and 11 is the magnetic rod. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a low-density ultralight foamed concrete testing tool includes a press 1 and a base 2; a support frame 3 is fixed on the base 2; the top of the support frame 3 is connected to the outer shell of the press 1; the lower pressing end of the press 1 is vertically downward and a pressure plate 4 is fixed thereon; the pressure plate 4 is correspondingly parallel to and above the base 2; an installation groove 5 is opened on the base 2; a support component for adjusting the support range of the foamed concrete sample is provided in the installation groove 5; like Figure 1-3 As shown, the support assembly includes a tray 6 that is inserted into the mounting slot 5; a plurality of slots 7 are evenly distributed in a grid pattern at the bottom of the inside of the tray 6; support blocks 8 are inserted into the slots 7 respectively; the upper end of the support block 8 is higher than the upper end of the tray 6.

[0014] In this method, the foamed concrete sample whose strength needs to be tested is placed on top of the support assembly. Then, using a suitable pressure set by the press 1, pressure is applied to the sample through the pressure plate 4. The pressure applied by the press 1 is gradually increased until the sample is crushed, thereby determining the compressive strength of the foamed concrete sample. Of course, this testing tool can also be used with a suitable clamp to fix and hold the sample in place before the compressive strength test, improving the stability of the sample position during the test.

[0015] The sample is supported by a combination of multiple support blocks 8. If it is necessary to test the compressive strength of the sample when it is only partially supported, the support blocks 8 in appropriate positions can be removed from the slots 7 according to the test requirements before the pressure test is performed. In this application, the multiple support blocks 8 are evenly distributed in a grid pattern, which can adapt to various structural forms of partial support and various arrangement forms of foamed concrete samples in actual buildings, thereby improving the comprehensiveness of the strength test of foamed concrete samples.

[0016] like Figure 2 As shown, the radial cross-section of the support block 8 is square, which makes it more flexible and convenient to remove and insert. The lower side length of the support block 8 is smaller than the upper side length, which improves the stability of the slot 7 and the support block 8. The upper ends of adjacent support blocks 8 are close to each other to ensure the integrity of the sample support surface and make the test results more reliable.

[0017] like Figure 1 , Figure 3 As shown, an electromagnetic chuck 9 is embedded inside the tray 6; the bottom of each slot 7 is positioned above the electromagnetic chuck 9; and the support block 8 is magnetically attached to the electromagnetic chuck 9. The electromagnetic chuck 9 magnetically connects to the support block 8, improving the stability of the connection between the support block 8 and the tray 6 and ensuring stable support for the sample. In addition, the magnetic connection can be released by de-energizing the electromagnetic chuck 9, making it easy to remove the support block 8.

[0018] like Figure 2 As shown, a bracket 10 is connected to one side of the tray 6; a magnetic rod 11 is correspondingly engaged on the bracket 10; the magnetic rod 11 is magnetically attracted to the top of the support block 8. Through the magnetic attraction between the magnetic rod 11 and the support block 8, the support block 8 in the appropriate position can be easily removed after the electromagnetic tray 6 is de-energized.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
