Technical Field
[0001] This utility model relates to the field of pile foundation testing technology, specifically a novel static load test reaction structure. Background Technology
[0002] The static load test reaction structure is a device used for static load testing. Static load testing is a test to detect the bearing capacity of engineering piles. It uses the settlement over a fixed period of time as a stability standard. By applying loads of different sizes, the settlement of the pile body is measured, and the bearing capacity of the pile is determined by interpreting the test data.
[0003] However, this reaction structure does not take into account that the shape, size, and distribution of pile foundations may vary in actual engineering projects. Different shapes of pile foundations experience different reaction forces through the secondary beams. Therefore, the reaction structure of the static load device needs to be customized according to different types of pile foundation testing environments, which increases the cost of conducting static load tests.
[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a new type of static load test reaction structure. Utility Model Content
[0005] The purpose of this invention is to provide a novel static load test reaction structure to solve the problem mentioned in the background art that different shaped pile foundations experience different reaction forces through secondary beams, requiring the static load device to be customized according to different pile foundation testing environments.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel static load test reaction structure, comprising a jack and a main beam, wherein a support beam is fixedly connected to the main beam and the support beam is located on the jack, a plurality of secondary beams are provided on the main beam, and three sliders are fixedly installed on the secondary beams, a first groove is provided on the main beam, a second groove is provided on the support beam, and the sliders are slidably installed in the first and second grooves, a limiting component is provided on the main beam, and the secondary beams are stably connected to the main beam through the limiting component.
[0007] Furthermore, the limiting component includes holes, fixing wires, and threaded holes. The holes are located on one side of the main beam, and there are multiple holes. The fixing wires are threaded into the holes, and the threaded holes are located on the slider, with one end of the fixing wire passing through the threaded holes.
[0008] Furthermore, multiple mounting blocks are fixedly installed on the main beam. A first connecting ring is connected to each mounting block, and the mounting block passes through the first connecting ring. A second connecting ring is slidably installed on the first connecting ring, and a stop bar is connected inside the second connecting ring.
[0009] Furthermore, the top of the mounting block is provided with a first threaded head, and the mounting block is threaded to a first connecting ring through the first threaded head. The bottom of the stop bar is provided with a second threaded head, and the stop bar is threaded to a second connecting ring through the second threaded head.
[0010] Furthermore, pile caps are symmetrically arranged on both sides of the jack, and both ends of the main beam are located on the pile caps.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model improves the flexibility of the static load test reaction structure by setting up movable secondary beams. First, jacks are placed above the pile foundation. The jacks generate upward or downward forces through hydraulic means, which simulate the load that the pile foundation may bear in actual use. The main beam is placed on the upper end of the jacks, and the secondary beams at both ends of the main beam slide in the first and second slide grooves through sliders. The position of the secondary beams can be flexibly adjusted arbitrarily. After the position of the secondary beams is adjusted, the position of the secondary beams is fixed by the limiting components to maintain the stability of the secondary beams. The new static load test reaction structure facilitates flexible adjustment of the secondary beams and can easily adjust the transmission path and distribution of the reaction force to ensure that the reaction force can effectively act on the test object. Thus, the static load test reaction structure can adapt to various types of pile foundation testing environments.
[0013] 2. This utility model maintains the stability of the static load testing device by setting up a stop bar. After the load block is placed on the beam, one end of the stop bar is engaged in the second connecting ring. Then, the second connecting ring is rotated to connect the stop bar to the second connecting ring through the second threaded head (the first connecting ring is pre-engaged with the mounting block, and the first connecting ring is rotated to connect the mounting block to the first connecting ring through the first threaded head, which is convenient for disassembly and assembly). The stop bar surrounds the load block to prevent excessive displacement of the load block on the beam, which helps to maintain the stability of the static load testing device and ensures the safety of personnel and equipment in the test site.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] like Figure 1 - Figure 4As shown, a novel static load test reaction structure includes a jack 1 and a main beam 11. A support beam 121 is fixedly connected to the main beam 11 and is located on the jack 1. Multiple secondary beams 12 are provided on the main beam 11, and three sliders 13 are fixedly installed on each secondary beam 12. A first groove 122 is provided on the main beam 11, and a second groove 123 is provided on the support beam 121. The sliders 13 are slidably installed within the first groove 122 and the second groove 123. A limit assembly is provided on the main beam 11, and the secondary beams 12 are limited by the limit assembly. The component is stably connected to the main beam 11. The static load test reaction structure is a device used for static load testing. Static load testing is a test to detect the bearing capacity of engineering piles. It uses the settlement over a fixed period as the stability standard. By applying loads of different sizes, the settlement of the pile body is measured, and the bearing capacity of the pile foundation is determined through the interpretation of the test data. However, in actual engineering, the shape, size, and distribution of pile foundations may vary. Different shaped pile foundations experience different reactions through the secondary beam 12, requiring different types of pile foundation testing rings. Customizing the reaction structure for the static load test device increases the cost of conducting static load tests. To improve the flexibility of the static load test reaction structure, a movable secondary beam 12 is installed. First, a jack 1 is placed above the pile foundation. The jack 1 generates upward or downward forces through hydraulic means, simulating the loads the pile foundation might bear in actual use. The jack 1 is the source of force in the entire reaction structure. A main beam 11 is placed on top of the jack 1, with the main beam 11 at both ends... The secondary beam 12 slides within the first slide groove 122 and the second slide groove 123 via the slider 13, allowing for flexible adjustment of its position. After the position of the secondary beam 12 is adjusted, it is fixed by a limiting component to maintain its stability. This novel static load test reaction structure facilitates flexible adjustment of the secondary beam 12, allowing for easy adjustment of the reaction force transmission path and distribution, ensuring that the reaction force can effectively act on the test object. This enables the static load test reaction structure to adapt to various types of pile foundation testing environments.
[0022] Furthermore, the limiting component includes a hole 14, a fixing wire 141, and a threaded hole 142. The hole 14 is provided on one side of the main beam 11, and there are multiple holes 14. The fixing wire 141 is threaded into the hole 14. The threaded hole 142 is provided on the slider 13, and one end of the fixing wire 141 passes through the threaded hole 142. After the position of the secondary beam 12 is adjusted, the fixing wire 141 passes through the hole 14 at that position, and then passes through the threaded hole 142 and is threadedly connected to the threaded hole 142, thus maintaining the positional stability of the secondary beam 12.
[0023] Example 2
[0024] like Figure 1 and Figure 4As shown, this utility model proposes a novel static load test reaction structure. Compared to Embodiment 1, as another implementation of this utility model, multiple mounting blocks 2 are fixedly installed on the main beam 11. A first connecting ring 22 is connected to the mounting block 2, and the mounting block 2 passes through the first connecting ring 22. A second connecting ring 221 is slidably installed on the first connecting ring 22, and a stop rod 23 is connected inside the second connecting ring 221. A first threaded head 21 is arranged around the top of the mounting block 2, and the mounting block 2 is threadedly connected to the first connecting ring 22 through the first threaded head 21. A second threaded head 231 is arranged around the bottom of the stop rod 23, and the stop rod 23 is threadedly connected to the second connecting ring 221 through the second threaded head 231. When maintaining a static load... To ensure the stability of the static load test device, a stop bar 23 is installed. After the load weight is placed on the beam, one end of the stop bar 23 is engaged in the second connecting ring 221. Then, the second connecting ring 221 is rotated to connect the stop bar 23 to the second connecting ring 221 through the second threaded head 231 (the first connecting ring 22 is pre-engaged with the mounting block 2, and the first connecting ring 22 is rotated to connect the mounting block 2 to the first connecting ring 22 through the first threaded head 21, which is convenient for disassembly and assembly). The stop bar 23 surrounds the load weight to prevent excessive displacement of the load weight on the beam, which helps to maintain the stability of the static load test device and ensures the safety of personnel and equipment in the test site.
[0025] Furthermore, pile caps 3 are symmetrically arranged on both sides of the jack 1, and the two ends of the main beam 11 are located on the pile caps 3. The pile caps 3 are used to support the two ends of the main beam 11 and provide stability to the main beam 11.
[0026] Working principle: When using this new type of static load test reaction structure, firstly, to improve the flexibility of the static load test reaction structure, movable secondary beams 12 are installed to facilitate the improvement of the flexibility of the static load test reaction structure. First, jacks 1 are placed above the pile foundation, and main beams 11 are placed on the upper end of jacks 1. The secondary beams 12 at both ends of the main beam 11 slide in the first slide groove 122 and the second slide groove 123 through sliders 13. The position of the secondary beams 12 can be flexibly adjusted arbitrarily. After the position of the secondary beams 12 is adjusted, the position of the secondary beams 12 is fixed by the limiting component to maintain the stability of the secondary beams 12. The new static load test reaction structure facilitates the flexible adjustment of the secondary beams 12, and can easily adjust the transmission path and distribution of the reaction force to ensure that the reaction force can effectively act on the test object, so that the static load test reaction structure can adapt to various types of pile foundation testing environments.
[0027] Finally, to maintain the stability of the static load test device, a stop bar 23 is installed. After the load block is placed on the beam, one end of the stop bar 23 is engaged in the second connecting ring 221. Then, the second connecting ring 221 is rotated to connect the stop bar 23 to the second connecting ring 221 through the second threaded head 231 (the first connecting ring 22 is pre-engaged with the mounting block 2, and the first connecting ring 22 is rotated to connect the mounting block 2 to the first connecting ring 22 through the first threaded head 21, which is convenient for disassembly and assembly). The stop bar 23 surrounds the load block to prevent excessive displacement of the load block on the beam, which helps to maintain the stability of the static load test device and ensures the safety of personnel and equipment in the test site.
[0028] This is the working principle of this new type of static load test reaction structure.
