Description

Technical Field

[0001] This utility model relates to the field of static load testing technology, and in particular to a T-beam static load testing frame. Background Technology

[0002] The T-beam static load test frame is a specialized loading device used to test the load-bearing capacity and structural integrity of prestressed concrete T-beams. It mainly consists of a reaction frame system, a hydraulic loading device, displacement sensors, and a data acquisition unit. Its working principle is as follows: Before the test, the T-beam to be tested is precisely hoisted and stably placed on the support platform of the test frame, ensuring that the supports at both ends of the beam meet the actual force boundary conditions. Subsequently, static loads are applied in stages at the mid-span of the T-beam or at key stress locations as required by the design using hydraulic jacks, simulating dead and live load conditions in actual engineering. However, the T-shaped cross-section of the T-beam results in a smaller bottom area than the top area, which can cause the beam to tilt to one side when placed on the platform. Therefore, this solution proposes a T-beam static load test frame to address this problem. Utility Model Content

[0025] This utility model provides, for example Figure 1-4 The T-beam static load test frame shown includes:

[0026] Fixed beam 1;

[0027] Top plate 2 is fixedly connected to the bottom of fixed beam 1;

[0028] The base plate 3 is located at the bottom of the top plate 2, and a connecting component 5 is provided at the connection between the top plate 2 and the base plate 3.

[0029] Jack 4 is located at the bottom of the top plate 2;

[0030] Support block 6 is set on the top of the base plate 3 and is used to restrict the T-beam;

[0031] Adjustment component 7 is located on the top of the base plate 3 and is used to adjust the position of the support block 6.

[0032] It should be noted that the jack 4 is an existing device used to apply static loads in stages at the mid-span of the T-beam or at key stress points required by the design, simulating dead and live load conditions in actual engineering. The fixed beam 1 is fixed to the top plate 2 by welding, and the bottom plate 3 is connected to the top plate 2 by the connecting component 5. In use, the T-beam is placed on top of the bottom plate 3. The support block 6 is installed on top of the bottom plate 3, and the support block 6 is moved to the required position by the adjusting component 7, so that the distance between the two support blocks 6 matches the distance at the bottom of the T-beam. This allows the bottom of the T-beam to be interlaced between the two support blocks 6, and the support blocks 6 restrict the bottom of the T-beam to prevent it from tilting.

[0033] Specifically, the connecting component 5 includes a first threaded rod 501 symmetrically interlocked on both sides of the top plate 2 and the bottom plate 3. A first nut 502 is threadedly fitted on the top of the first threaded rod 501, and a second nut 503 is threadedly fitted on the bottom of the first threaded rod 501.

[0034] It should be noted that the first threaded rod 501 is inserted and connected to both sides of the top plate 2 and the bottom plate 3, and the two nuts are respectively set on the opposite sides of the top plate 2 and the bottom plate 3. The movement of the top plate 2 and the bottom plate 3 is restricted by the two nuts, thereby restricting the bottom plate 3 to the bottom of the top plate 2.

[0035] Specifically, the adjustment component 7 includes a fixing block 701 fixedly connected to the top of the base plate 3. A drive groove 702 is provided on one side of the fixing block 701.

[0036] It should be noted that the drive block 703 is adapted to the drive groove 702 and both are cubic, allowing the drive block 703 to slide inside the drive groove 702 without rotating inside it. The fixed bearing 705 is a conventional ball bearing, which is used to fix the position of the second threaded rod 706 without affecting its rotation. When the position of the support block 6 needs to be adjusted, the torsion cap 707 is turned, which drives the second threaded rod 706 to rotate. The rotating second threaded rod 706 drives the drive block 703, which is threaded to it but cannot rotate, to move. The moved drive block 703 then drives the support block 6 to move.

[0037] Specifically, the fastener 8 includes a connecting groove 803 opened on one side of the driving block 703, a connecting block 804 fixedly connected to one side of the support block 6, the connecting block 804 being inserted into the interior of the connecting groove 803, a storage groove 802 opened on the top of the driving block 703, a bolt 801 being threadedly inserted into the inner wall of the bottom end of the storage groove 802, and the bolt 801 being threadedly inserted into the top of the connecting block 804.

[0038] It should be noted that the connecting groove 803 is adapted to the connecting block 804, allowing the connecting block 804 to be inserted into one side of the drive block 703 through the connecting groove 803. The storage groove 802 is adapted to the thread head of the bolt 801. When it is necessary to fix the position of the connecting block 804, the bolt 801 is threaded through and connected to the inner wall of the bottom of the storage groove 802, and the connecting block 804 is fixed inside the connecting groove 803 by the bolt 801, thereby fixing the position of the support block 6 by the fixed position of the connecting block 804.
