Description

Technical Field

[0001] This utility model relates to the field of building construction materials technology, and in particular to a testing device for building construction materials. Background Technology

[0002] Steel bars are used in building construction. As the "skeleton" of concrete structures, steel bars work together with concrete to significantly improve the structure's load-bearing capacity, crack resistance, earthquake resistance, and durability.

[0003] As an important building material in house construction, steel bars have high requirements for compressive strength. Therefore, after the steel bars are produced, they need to be tested for compressive strength. Traditional testing can only test steel bars of a fixed diameter. When it is necessary to test steel bars of another diameter, the workpiece needs to be replaced. The replacement process is extremely complicated and inconvenient, which is not conducive to testing the compressive strength of steel bars of different diameters. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4A testing device for building construction materials includes a testing platform 1 and a steel bar body 5. Main support plates 6 are fixedly installed at both ends of the testing platform 1. Placement grooves 61 are formed on the main support plates 6. Arc-shaped movable grooves 62 are formed on both sides of the inner wall of the placement grooves 61. Limiting holes 621 are formed on both sides of the inner wall of the arc-shaped movable grooves 62. Two mounting blocks 10 are fixedly installed on the placement grooves 61. A connecting rod 11 is fixedly installed between the two mounting blocks 10. A first support plate 8 and a second support plate 9 are rotatably mounted on the connecting rod 11. One end of the first support plate 8 and the second support plate 9 is movably located within the two arc-shaped movable grooves 62, respectively. The steel bar body 5 is placed on the first support plate 8 and the second support plate 9.

[0017] The first support plate 8 has two first rotating sleeves 82 at one end. The first rotating sleeves 82 are rotatably sleeved on the connecting rod 11, so that the first support plate 8 can rotate about the connecting rod 11 as the axis.

[0018] Meanwhile, a first limiting groove 81 is opened at one end of the first support plate 8, and a limiting pin 7 passes through the limiting hole 621 and is inserted into the first limiting groove 81 to limit the first support plate 8.

[0019] Furthermore, a second rotating sleeve 92 is provided at one end of the second support plate 9. The second rotating sleeve 92 is rotatably sleeved on the connecting rod 11, and the second rotating sleeve 92 is located between the two first rotating sleeves 82, so that the second support plate 9 can rotate about the connecting rod 11 as the axis.

[0020] Meanwhile, a second limiting groove 91 is opened at one end of the second support plate 9, and a limiting pin 7 passes through the limiting hole 621 and is inserted into the second limiting groove 91 to limit the second support plate 9.

[0021] Meanwhile, a cylinder 2 is fixedly installed on the top of the testing platform 1. The cylinder 2 drives the installation of the lower pressure plate 3. A lower pressure block 31 is set on the bottom surface of the lower pressure plate 3. The lower pressure block 31 presses down on the steel bar body 5, thereby conducting a compressive strength test on the steel bar body 5.

[0022] Furthermore, the four ends of the lower pressure plate 3 are slidably sleeved on the four connecting columns of the testing platform 1, and four springs 4 are fixedly installed at the bottom of the lower pressure plate 3. The four springs 4 are respectively sleeved on the four connecting columns of the testing platform 1, and the other end of the springs 4 is fixedly connected to the testing platform 1. When the lower pressure plate 3 moves down, the springs 4 are compressed, so that the lower pressure plate 3 moves down stably, which is beneficial for testing the compressive strength of the reinforcing bars.

[0023] In this embodiment, the steel bar body 5 is placed between the first support plate 8 and the second support plate 9. At this time, the cylinder 2 is activated and a suitable value is set. The cylinder 2 drives the lower pressure plate 3 to move down. The lower pressure plate 3 moves down to compress the spring 4. The lower pressure block 31 presses down on the steel bar body 5. The degree of bending of the steel bar body 5 is observed, and the compressive strength of the steel bar body 5 is tested. A suitable value can be set according to different steel bars. When another rebar needs to be tested, pull the limiting pin 7 to remove it. Then rotate the first support plate 8, which rotates around the connecting rod 11. When the first support plate 8 rotates to the predetermined position, insert the limiting pin 7 through the limiting hole 621 into the first limiting groove 81. The adjustment method of the second support plate 9 is the same as that of the first support plate 8. At this time, the included angle between the first support plate 8 and the second support plate 9 changes, so that rebars of different diameters can be placed, which is convenient for testing rebars of different diameters.

[0024] In this invention, steel bars of different diameters can be placed by changing the included angle between the first support plate 8 and the second support plate 9, thereby enabling the compressive strength testing of steel bars of different diameters. This invention offers high flexibility and facilitates the compressive strength testing of steel bars of different diameters.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
