Description

Technical Field

[0001] This utility model belongs to the field of rebound hammer technology, specifically relating to a rebound hammer for testing the strength of laminated plates that facilitates multi-angle measurement. Background Technology

[0002] In the field of construction engineering, composite slabs are an important building component, and their strength testing is a crucial step in ensuring project quality. Currently, rebound hammers are widely used for strength testing of composite slabs.

[0003] However, existing rebound hammers have many limitations in practical use. Firstly, traditional rebound hammers struggle to perform multi-angle measurements. When testing laminated slabs at different locations and installation angles, operators must frequently adjust their posture or use auxiliary tools to change the rebound hammer's angle, which is not only inconvenient but also prone to measurement errors. Secondly, when testing the strength of laminated slabs located on indoor rooftops, operators must hold the rebound hammer up for extended periods, leading to operator fatigue, reduced testing efficiency and accuracy, and potential safety hazards. Furthermore, existing rebound hammers exhibit poor stability when placed, especially when used with lifting mechanisms, easily causing swaying that can affect the reliability of test results.

[0004] Therefore, there is an urgent need for a rebound hammer that is easy to measure from multiple angles and suitable for strength testing of roof composite slabs. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a rebound hammer for testing the strength of laminated slabs, which facilitates multi-angle measurements. The specific technical solution is as follows:

[0006] A rebound hammer for testing the strength of composite slabs, which facilitates multi-angle measurement, includes a rebound hammer body, an angle adjustment mechanism for adjusting the angle is externally mounted on the rebound hammer body, a lifting mechanism for adjusting the height is mounted on the angle adjustment mechanism, and a support member is mounted on the lower part of the lifting mechanism.

[0007] The angle adjustment mechanism includes a support plate fixed to the lifting end of the lifting mechanism. A bracket is welded to the surface of the support plate. The bracket has a "U"-shaped structure, and a clamp is rotatably installed at the end of the bracket. The clamp is fixed to the middle of the rebound hammer body by bolts. A support plate is welded to the middle of the clamp. A screw is rotatably installed on the surface of both the support plate and the bracket. An internal threaded sleeve is screwed between the two screws. The threads at both ends of the internal threaded sleeve are arranged in opposite directions.

[0008] Preferably, the lifting mechanism includes a support rod and a lifting rod arranged in parallel, the support plate is fixed to the upper end of the lifting rod, and a first rotating rod and a second rotating rod arranged in parallel are rotatably installed between the support rod and the lifting rod. A pull rope is installed at the end of the second rotating rod away from the lifting rod, and the rotation axes of the support rod, the first rotating rod, the lifting rod and the second rotating rod form a parallelogram.

[0009] Preferably, the support member includes a limiting insertion hole opened on the bottom surface of the lower end of the support rod, a magnet is bonded in the limiting insertion hole, a side groove is opened on the side surface of the lower end of the support rod, a support iron plate is inserted into the side groove, and the end of the support iron plate is in contact with the magnet. There are four support iron plates and four side grooves in a circular array, and the support iron plates and the side grooves correspond one-to-one.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The angle adjustment mechanism mounted on the outside of the rebound hammer facilitates strength testing of composite slabs. By adjusting the angle of the rebound hammer itself, different angles can be measured during strength testing of the composite slabs. The angle adjustment mechanism consists of a support plate, bracket, clamp, support plate, internal threaded sleeve, and screw. The threads at both ends of the internal threaded sleeve are reversed, allowing the screws at both ends to move closer or further apart as the sleeve rotates. This allows for angle adjustment of the bracket and clamp. The clamp is fixed to the outside of the rebound hammer, achieving the purpose of adjusting the angle of the rebound hammer. The lifting mechanism mounted on the angle adjustment mechanism allows for raising and lowering of the rebound hammer itself, facilitating strength testing of composite slabs located on indoor roofs. This eliminates the fatigue caused by the need to lift the rebound hammer itself for long testing times. The support component installed at the bottom of the lifting mechanism increases the stability of the lifting mechanism when placed indoors.

[0012] 2. The lifting mechanism, consisting of a support rod, a lifting rod, a first rotating rod, a second rotating rod, and a pull rope, allows the second rotating rod to rotate by pulling down the pull rope. Since the rotation axes of the support rod, the first rotating rod, the lifting rod, and the second rotating rod form a parallelogram, the second rotating rod moves the lifting rod upward. This allows the lifting rod to move the rebound hammer body upward via the angle adjustment mechanism, facilitating the rebound hammer body to perform strength testing on the roof composite slab.

[0013] 3. The support component consists of a support iron plate, a limiting insertion hole, a side groove, and a magnet. The support iron plate is inserted into the side groove opened on the side surface of the lower end of the support rod and then contacts the magnet, which makes it easy to fix the support iron plate to the lower end of the support rod. There are four support iron plates in a circular array, which makes it easier to increase the support area at the lower end of the support rod after the support iron plates are installed. At the same time, it is also easy to remove the support iron plates, which makes it easy to transport the rebound spring after disassembly. Attached Figure Description

[0019] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-4 This embodiment provides the following technical solution: a rebound hammer for testing the strength of composite plates that facilitates multi-angle measurement, including a rebound hammer body 1, an angle adjustment mechanism 2 for adjusting the angle is installed outside the rebound hammer body 1, a lifting mechanism for adjusting the height is installed on the angle adjustment mechanism 2, and a support member is installed at the lower part of the lifting mechanism.

[0021] The angle adjustment mechanism 2 includes a support plate 21 fixed at the lifting end of the lifting mechanism. A bracket 22 is welded to the surface of the support plate 21. The bracket 22 has a "U"-shaped structure, and a clamp 23 is rotatably installed at the end of the bracket 22. The clamp 23 is fixed to the middle of the rebounder body 1 by bolts. A support plate 24 is welded to the middle of the clamp 23. A screw 26 is rotatably installed on the surface of both the support plate 24 and the bracket 22. An internal threaded sleeve 25 is screwed between the two screws 26. The threads at both ends of the internal threaded sleeve 25 are arranged in opposite directions.

[0022] In this embodiment, the angle adjustment mechanism 2 installed outside the rebound hammer body 1 facilitates the adjustment of different angles of the rebound hammer body 1 when performing strength testing on the stacked plates. The angle adjustment mechanism 2 consists of a support plate 21, a bracket 22, a clamp 23, a support plate 24, an internal threaded sleeve 25, and a screw 26. The threads at both ends of the internal threaded sleeve 25 are reversed, allowing the screws 26 at both ends to move closer or further apart when the internal threaded sleeve 25 rotates. The bracket 22 and clamp 23 are separated, thus enabling angle adjustment of the bracket 22 and clamp 23. The clamp 23 is fixed to the outside of the rebound hammer body 1, achieving the purpose of adjusting the angle of the rebound hammer body 1. The lifting mechanism installed on the angle adjustment mechanism 2 facilitates the lifting of the rebound hammer body 1, making it convenient for strength testing of composite slabs located on indoor roofs. This solves the problem of fatigue caused by the long testing time when users need to lift the rebound hammer body 1 to test the strength of the composite slabs on the roof. The support component installed at the bottom of the lifting mechanism increases the stability of the lifting mechanism when placed indoors.

[0023] Specifically, the lifting mechanism includes a support rod 3 and a lifting rod 4 arranged in parallel. The support plate 21 is fixed to the upper end of the lifting rod 4. A first rotating rod 5 and a second rotating rod 6 arranged in parallel are rotatably installed between the support rod 3 and the lifting rod 4. A pull rope 7 is installed at the end of the second rotating rod 6 away from the lifting rod 4. The rotation axes of the support rod 3, the first rotating rod 5, the lifting rod 4 and the second rotating rod 6 form a parallelogram.

[0024] In this embodiment, the lifting mechanism, consisting of a support rod 3, a lifting rod 4, a first rotating rod 5, a second rotating rod 6, and a pull rope 7, facilitates the rotation of the second rotating rod 6 by pulling down the pull rope 7. Since the rotation axes of the support rod 3, the first rotating rod 5, the lifting rod 4, and the second rotating rod 6 form a parallelogram structure, the second rotating rod 6 moves the lifting rod 4 upward, thereby enabling the lifting rod 4 to move upward through the angle adjustment mechanism 2, which in turn moves the rebound hammer body 1 upward, facilitating the rebound hammer body 1 to perform strength testing on the roof composite slab.

[0025] Specifically, the support includes a limiting insertion hole 9 opened on the bottom surface of the lower end of the support rod 3, a magnet 11 is bonded inside the limiting insertion hole 9, a side groove 10 is opened on the side surface of the lower end of the support rod 3, a support iron plate 8 is inserted into the side groove 10, and the end of the support iron plate 8 is in contact with the magnet 11. There are four support iron plates 8 and four side grooves 10 in a circular array, and the support iron plates 8 and the side grooves 10 correspond one-to-one.

[0026] In this embodiment, a support member consisting of a support iron plate 8, a limiting insertion hole 9, a side groove 10, and a magnet 11 is used. The support iron plate 8 is inserted into the side groove 10 opened on the side surface of the lower end of the support rod 3 and then contacts the magnet 11, which makes it easy to fix the support iron plate 8 to the lower end of the support rod 3. There are four support iron plates 8 in a circular array, which makes it easy to increase the support area of ​​the lower end of the support rod 3 after the support iron plates 8 are installed. At the same time, it is also easy to disassemble the support iron plates 8, which makes it easy to transport the rebound spring after disassembly.
