Description

Technical Field

[0001] The utility model relates to the field of concrete, in particular to a strength detection device for concrete engineering. Background Art

[0002] The strength grade of concrete refers to its compressive strength. After normal construction, the strength grade of concrete should be determined according to its standard cubic compressive strength value. In existing technology, a rebound hammer is often used to test the strength of concrete. Its working principle is that a spring-driven hammer strikes a striking rod perpendicular to the concrete surface with constant kinetic energy, causing the concrete to deform locally and absorb some of the energy. The remaining energy is converted into the hammer's rebound force.

[0003] After searching, a utility model concrete strength detection device for water conservancy project inspection with publication number CN218180568U is found, which includes a rebound shell, a display screen, a striking rod and a lock. The striking rod is installed at one end of the rebound shell, and the display screen is installed at the other end of the top of the rebound shell. The numerical value generated after the local concrete measurement can be displayed through the display screen, which is convenient for statistical conversion. The lock is installed at the other end of the bottom of the rebound shell, and an integrated card seat is provided at one end of the rebound shell; by arranging a protective cover at one end of the rebound shell, when the striking rod is retracted into the rebound shell, the protective cover prevents the striking rod from being bumped and hit during carrying and placement, and prevents the striking rod from bending and deforming; by arranging a hand strap on one side of the rebound shell and fixing a pressing plate on the other end of the rebound shell, when the device is used for monitoring, the hand strap and the pressing plate can be used to limit the holding hand to prevent the rebound instrument from falling out of the hand during measurement and pressing.

[0004] Existing strength testing devices for concrete engineering projects need to be manually fixed on the concrete plane. On the one hand, manual fixation increases the use of manpower resources, but on the other hand, it also reduces the measurement accuracy due to operational errors. At the same time, the upright upward rebound hammer has no fulcrum and no limit device, which can easily cause the rod core of the rebound hammer to tilt or deviate, resulting in inaccurate measurement values. In the above-mentioned comparative case, there is no limit support, so during the concrete strength test, tilt or deviation will occur, resulting in non-standard test values.

[0005] Therefore, it is necessary to invent a strength detection device for concrete engineering to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a strength testing device for concrete engineering, which forms a supporting effect on the support plate by pressing the supporting plate and the fixing rods and connecting plates on the upper and lower sides against the concrete wall surface, and then presses the rebound hammer inside the support plate, and uses the sliders on the two sides of the rebound hammer to slide in the slide groove in the fixing plate to keep the rebound hammer and the concrete wall surface in a vertical state, effectively reducing the error of the detection process and improving the accuracy of the detection data, so as to solve the problems raised in the above-mentioned background technology.

The fixed rods are fixed on the upper and lower sides of the support plate. One end of the fixed rod is movably connected to the movable block, and one side of the movable block is fixedly installed with a connecting plate.

[0012] Preferably, an anti-slip sticker is attached to one side of the connecting plate, and the connecting plate and the anti-slip sticker are arranged in four groups.

The two sides of the support plate 1 are movably connected with movable rods 4. The clamping plates 5 are fixed to one end of the movable rods 4. A limiting mechanism 7 is provided on each side of the upper and lower sides of the support plate 1.

[0031] The rebound hammer 8 is arranged inside the support plate 1 and is used to detect the strength of concrete. A handle 9 is fixedly installed at one end of the rebound hammer 8, and sliders 10 are fixedly installed on both sides of the outside of the rebound hammer 8. Fixed plates 11 are fixedly installed on both sides of one side of the support plate 1, and a slide groove 12 is provided on the inner surface of the fixed plate 11. By pressing the support plate 1 and the fixing rods 301 and the connecting plate 303 on the upper and lower sides tightly against the concrete wall, a supporting effect is formed on the support plate 1, and then the rebound hammer 8 inside the support plate 1 is pressed, and the sliders 10 on both sides of the outside of the rebound hammer 8 are used to slide in the slide groove 12 in the fixed plate 11 to keep the rebound hammer 8 vertical to the concrete wall, which effectively reduces the error of the detection process and improves the accuracy of the detection data.

[0032] like Figure 1 and Figure 2 As shown, the support mechanism 3 includes a fixed rod 301, a movable block 302, a connecting plate 303, and an anti-slip sticker 304. The fixed rods 301 are fixed on the upper and lower sides of the support plate 1.

After adjustment, release the pull ring 703 and use the spring 705 outside the telescopic rod 702 to rebound and insert the plug rod 706 into the limit groove 6 on the plug rod 706 to limit and fix it. In this way, when the clamping width on both sides of the concrete wall is met, it is convenient for the inspector to conduct inspection and record by one person. Next, the support The plate 1 and the fixing rods 301 and the connecting plate 303 on the upper and lower sides are tightly attached to the concrete wall, forming a supporting effect on the support plate 1. When everything is fixed, hold the handle 9 at the rear of the rebound test hammer 8, press and push the rebound test hammer 8 inside the support plate 1, and use the sliders 10 on both sides of the outside of the rebound test hammer 8 to slide in the slide groove 12 in the fixed plate 11 to keep the rebound test hammer 8 vertical to the concrete wall, effectively reducing the error of the detection process and improving the accuracy of the detection data. Finally, the concrete wall strength value is obtained. When the device is not in use, the entire detection device is removed through the above steps. In this way, the use process of the strength detection device for concrete engineering is completed.
