However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a building static load test reference beam device, including: a bottom plate 1 and a beam body 2, the top of the bottom plate 1 is symmetrically fixedly connected to the side frame 4, and the top of the bottom plate 1 is fixedly connected to the slide rail 3; a mounting assembly 7, the number of the mounting assemblies 7 is set to two, the two mounting assemblies 7 are respectively fixedly connected to the two side frames 4, and the mounting assembly 7 includes a mounting plate 701; a support assembly 8, the number of the support assemblies 8 is set to multiple, and the multiple support assemblies 8 are all slidably connected to the outer surface of the slide rail 3, the support assembly 8 includes a slider 801, the top of the slider 801 is fixedly connected to a connecting plate 802, the top of the connecting plate 802 is fixedly connected to a second screw 804, the outer surface of the second screw 804 is threadedly connected to a threaded sleeve 805, and the upper end surface of the threaded sleeve 805 is rotatably connected There is a support block 806, the beam body 2 is fixedly connected between the two mounting plates 701, the support block 806 is fitted with the outer surface of the beam body 2, and a plurality of positioning holes 5 are symmetrically provided on the outer surface of the side frame 4. The outer surface of the mounting plate 701 is symmetrically fixedly connected with a first screw rod 702, and a nut 703 is threadedly connected to the outer surface of the first screw rod 702. The outer surface of the first screw rod 702 is plugged into the inner surface of the positioning hole 5, and the nut 703 is located on the outer side of the side frame 4. A plurality of threaded holes 6 are symmetrically provided on the top of the bottom plate 1, and bolts 803 are symmetrically penetrated and slidably connected to the top of the connecting plate 802. The outer surface of the bolt 803 is threadedly connected to the inner surface of the threaded hole 6, and the top of the connecting plate 802 is symmetrically fixedly connected with a telescopic rod 808, and the telescopic rod 808 is fixedly connected to the support block 806.

[0024] The effect achieved by the entire embodiment 1 is that when a static load test is performed on a building, the beam body 2 is installed at the side position of the pile body according to the test requirements. When installing the beam body 2, the first screw rod 702 is inserted into the positioning hole 5 at a suitable height, and the nut 703 is tightened to clamp and fix the mounting plate 701, thus completing the installation and fixation of the beam body 2. Subsequently, a magnetic table seat and a displacement sensor are installed above the beam body 2 to complete the test. According to the length of the beam body 2 used in the test, several support blocks 806 can be installed to provide support for the beam body 2. The connecting plate 802 can slide freely along the slide rail 3 to adjust the position. After reaching the appropriate position, screw the bolt 803 into the threaded hole 6 to clamp the position of the connecting plate 802, and then screw the threaded sleeve 805. The threaded sleeve 805 rotates on the outside of the second screw 804 to drive the support block 806 to move upward. The telescopic rod 808 is set to provide a limit for the support block 806. After the support block 806 moves up to the position that fits the beam body 2, it can provide support for the beam body 2, effectively avoiding the problem of the beam body 2 sagging due to gravity, so that the beam body 2 is in a horizontal state for testing, ensuring that the displacement sensor is in a stable position for use, thereby improving the accuracy of the static load test results.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, a through hole 807 is opened on the outer surface of the support block 806, a support block 704 is fixedly connected to the outer surface of the mounting plate 701, the support block 704 is in contact with the outer surface of the beam body 2, and an infrared laser emitter 705 is fixedly connected to the outer surface of the support block 704.

[0026] The effect achieved by the entire embodiment 2 is that after the beam body 2 is supported by the support block 806, in order to ensure that the beam body 2 is in a horizontal state after the support is completed, the infrared laser emitter 705 is started to emit an infrared signal. Since the support block 704 and the support block 806 are in a fit state with the beam body 2, when the beam body 2 is in a horizontal state, the laser emitted by the infrared laser emitter 705 will pass through the through hole 807. At this time, it can be determined whether the beam body 2 is in a horizontal state. By calibrating the horizontal position of the beam body 2, the accuracy of the test is improved.

[0027] Working principle: When conducting a static load test on a building, the beam body 2 is installed at the side of the pile body according to the test requirements. When installing the beam body 2, the first screw rod 702 is inserted into the positioning hole 5 of a suitable height, and the nut 703 is tightened to clamp the mounting plate 701 to complete the installation and fixation of the beam body 2. Then, a magnetic table seat and a displacement sensor are installed above the beam body 2 to complete the test. According to the length of the beam body 2 used in the test, several support blocks 806 can be installed to provide support for the beam body 2. The connecting plate 802 can slide freely along the slide rail 3 to adjust the position. After adjusting to the appropriate position, the bolt 803 is screwed into the threaded hole 6 to clamp the position of the connecting plate 802, and then the threaded sleeve 805 is screwed. The threaded sleeve 805 rotates on the outside of the second screw rod 804 to drive the support block 806 to move upward, and the telescopic rod 808 is used to move the support block 806 upward. The setting provides a limit for the support block 806. After the support block 806 moves up to the position of fitting the beam body 2, it can provide support for the beam body 2, effectively avoiding the problem of the beam body 2 sagging due to gravity, so that the beam body 2 is in a horizontal state for testing, ensuring that the displacement sensor is in a stable position for use, thereby improving the accuracy of the static load test results. After the beam body 2 is supported by the support block 806, in order to ensure that the beam body 2 is in a horizontal state after the support is completed, the infrared laser transmitter 705 is started to send an infrared signal. Since the support block 704 and the support block 806 are both in a fit state with the beam body 2, when the beam body 2 is in a horizontal state, the laser emitted by the infrared laser transmitter 705 will pass through the through hole 807. At this time, it can be determined whether the beam body 2 is in a horizontal state. By calibrating the horizontal position of the beam body 2, the accuracy of the test is improved.
