Description

Technical Field

[0001] The utility model belongs to the technical field of engineering detection, and in particular relates to a modular circulatory hydrostatic loading device. Background Art

[0002] At present, there are generally two ways to uniformly load the floor: one is to use bricks, stones, and weights as stacking materials for direct loading. In this way, workers need to transport the stacked materials back and forth to the floor, and constantly adjust the load size according to the experimental requirements. The experimental time and cost are relatively large; the second method is hydrostatic loading, which takes the form of masonry pools, temporary loading pools assembled with wood and plastic film liner, and finished water storage bags; masonry pools are more expensive, and the masonry pools must wait for solidification and hardening, so the test cycle is long, and the pools cannot be recycled, which can easily lead to waste; in addition, the masonry pools need to be designed according to the size of the experimental floor, and cannot be modularly designed, so they are not very versatile; the use of wood and plastic film liner The temporary water storage tank composed of wood has a shallow water capacity and cannot be implemented for large-scale loading experiments. In addition, this method consumes a lot of wood and cannot be recycled, resulting in a large amount of wood waste. Moreover, the connection of the temporary water storage tank assembled with wood is difficult to ensure, and the lateral stability is poor. Once the lateral water pressure is too large, it is easy to cause the pool wall to overturn, posing a great threat to the life safety of the experimenters on site. When using the finished water tank for experiments, due to the different floor areas, multiple water tanks with different areas need to be arranged, which results in different pressures on the bottom of the water tank for the same weight of water in different water tanks. Therefore, when conducting a uniformly distributed load experiment, the water capacity of different water tanks must be calculated multiple times. The calculation process is cumbersome and the amount of calculation is large.

[0003] In recent years, some new loading technologies have emerged, but the new technologies also have some disadvantages: for example, some loading devices are relatively bulky overall, and the size adjustment process is cumbersome when loading on floors of different areas. In addition, during the installation of fixed connectors, it is necessary to penetrate the plastic film liner. When the water filling depth is large, there is a risk of water leakage at the penetration point; some other loading devices not only have special components that require special customization and are difficult to purchase on the market, but also the lateral restraint components are supported by only a few tie rods, and the gaps between the tie rods are large. As the water injection depth increases, the lateral pressure of the water also increases. Due to the low stiffness of the lateral restraint components, it is difficult to maintain a large lateral water pressure, and water is easy to overflow from the gaps, which will endanger the safety of on-site test personnel. Summary of the invention

[0004] In response to the problems existing in the above-mentioned prior art, the utility model provides a modular and recyclable hydrostatic loading device, which has a strong load-bearing capacity, can avoid the side wall overturning, and can be assembled according to the load area, and can adapt to different experimental conditions. At the same time, it can better achieve load uniformity and can better simulate the real uniform loading state. Moreover, its loading or unloading process is relatively convenient, which is conducive to reducing the transportation time and labor costs. In addition, the device has a low manufacturing cost and is easy to dismantle and recycle, which can significantly reduce the experimental cost.

[0005] In order to achieve the above-mentioned object, the utility model provides a modular circulatory hydrostatic loading device, comprising a bottom bearing member, a lateral restraint member A, a lateral restraint member B, a water-proof liner, a connecting buckle and a connecting pipe;

[0006] The bottom bearing member is a rectangular metal mesh plate, which is horizontally arranged on the floor specimen;

[0007] The lateral restraints A and B are both rectangular metal mesh plates, the heights of the lateral restraints A and B are the same, and the lengths of the lateral restraints A and B are respectively consistent with the lengths of the two adjacent sides of the bottom bearing member; the two lateral restraints A are relatively arranged above the two edges of the bottom bearing member, and the two lateral restraints B are relatively arranged above the other two edges of the bottom bearing member, and the two lateral restraints A, the two lateral restraints B and the bottom bearing member form a bearing box with an open upper end; the edges between the bottom bearing member and the lateral restraints A, the edges between the bottom bearing member and the lateral restraints B, and the edges between the lateral restraints A and the lateral restraints B are all fixedly connected to each other by a plurality of connecting buckles buckled on the connecting edges;

[0008] The size of the water-proof liner matches the size of the inner cavity of the carrying box, and is snugly arranged inside the carrying box;

[0009] The connecting buckle is composed of a metal clamp block 1, a metal clamp block 2 and a connecting bolt, wherein the metal clamp block 1 and the metal clamp block 2 are respectively provided with an upper groove and a lower groove in the central area of ​​each other's opposite sides, the metal clamp block 1 is provided with a pair of upper through holes on the opposite sides of the upper groove, and the metal clamp block 2 is provided with a pair of lower threaded holes on the opposite sides of the lower groove; when the metal clamp block 1 and the metal clamp block 2 are relatively fitted, the upper groove and the lower groove are buckled to form a strip-shaped receiving groove, and the pair of upper through holes and the pair of lower threaded holes are respectively aligned to form two mounting screw hole groups located on both sides of the strip-shaped receiving groove; the two connecting bolts are respectively connected to the two mounting screw hole groups through threaded fitting, and the metal clamp block 1 and the metal clamp block 2 are pressed and connected into an integral structure;

[0010] There are four connecting tubes, which are respectively arranged at the bottom of the four sides of the carrying box; one end of the connecting tube passes through the grid of the lateral restraint A or the lateral restraint B and then passes through the watertight liner to enter the inner cavity of the watertight liner, and the other end is exposed to the outside of the carrying box, and the connecting tube is fixedly connected to the lateral restraint A or the lateral restraint B, and a waterproof sealing assembly is provided at the connection between the connecting tube and the watertight liner.

[0011] Furthermore, in order to facilitate the control of the water injection and discharge process, a ball valve is serially connected to the connecting pipe at the part outside the carrying box.

[0012] Furthermore, in order to facilitate manual assembly and removal of the connecting buckle, the connecting bolt is a butterfly bolt.

[0013] As a preference, the waterproof liner is made of plastic or waterproof cloth or other waterproof materials.

[0014] As a preferred embodiment, the metal block 1 and the metal block 2 have the same shape and size.

[0015] Preferably, the bottom bearing member, the lateral restraint member A and the lateral restraint member B are all made of galvanized wire mesh.

[0016] In the utility model, the lateral restraints and the bottom bearing member are both made of metal mesh plates, and the adjacent mesh plates are connected by connecting buckles to form a bearing box with an upper opening, which can ensure that the overall structure of the bearing box has good stability and bearing strength. The metal clamps one and two are used to form a connecting buckle with a strip receiving groove in cooperation with the connecting bolts, which can facilitate the rapid assembly and separation between the bottom bearing member and the edge of the lateral restraint member A, between the bottom bearing member and the edge of the lateral restraint member B, and between the edges of the lateral restraint members A and B, and can make the overall rigidity of the device stronger. After the floor slab specimen is destroyed, the device can still maintain a certain rigidity, and will not cause secondary damage to the on-site experimenters due to the destruction of the device. In addition, this connection method can also facilitate the assembly of lateral restraint components of different sizes, so that experimental devices of different moduli can be formed, and modular loading tests can be performed on floors of different areas, which greatly increases the scope of application of the device. Furthermore, by connecting the edges of adjacent lateral restraints with connecting buckles, the gaps between the lateral restraint components of the device can be reduced, ensuring the stability of the lateral restraint components. After the water injection depth increases significantly, the entire load-bearing box can still withstand greater lateral water pressure, avoiding the sidewall overturning caused by excessive lateral water pressure. By arranging a water-proof liner inside the load-bearing box, it is convenient to avoid water leakage after liquid is injected, making the test less dangerous. By providing connecting pipes at the bottom of the four sides of the carrying box and making a waterproof and sealed connection between the connecting pipes and the waterproof liner, it is possible to use the connecting pipes to cascade multiple modular circulatory hydrostatic loading devices in a through-type manner, thereby ensuring that the water storage spaces of the modular circulatory hydrostatic loading devices in all directions can maintain effective communication during the water injection process, further ensuring that the liquid levels in each modular circulatory hydrostatic loading device are flush, effectively avoiding the uneven load distribution caused by uneven liquid levels, further ensuring the degree of consistency between the measured data and the actual situation, and providing more realistic experimental data for subsequent work. Compared with the traditional brick, stone, and weight loading methods, this device can be assembled according to the load area, and can adapt to different experimental conditions, solving the problem that the size of the traditional loading device cannot be changed with the change of the floor area, and significantly improving the versatility of the loading device. At the same time, the device can better achieve load uniformity, better simulate the actual uniform loading state, and effectively avoid the situation where the experiment is inconsistent with the actual state due to uneven loading, thereby providing more realistic data for engineering structure design. Moreover, the loading or unloading process of the device is relatively convenient, avoiding the situation of traditional back-and-forth transportation of loading materials, solving the problem of time-consuming and labor-intensive traditional sand and gravel loading, and the problem of inconvenient installation of hydrostatic loading devices, while reducing transportation time and labor costs.In addition, the device is made of low-cost materials, is easy to purchase, does not require special customization and processing, and is easy to dismantle and recycle, greatly reducing experimental costs.
