Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a device for self-balancing detection of the bearing capacity of a reaction beam. Background Art

[0002] Anchor piles are often used to reinforce the foundation of buildings. The principle is to use the anchor pile frame and reaction beam as a reaction device to press the anchor pile into the foundation soil, and finally use concrete to seal the pile to form an integral whole with the building floor to provide bearing capacity, thereby reinforcing the building foundation. This method can be used to reinforce the foundation of a building.

[0003] Using reaction beams and anchor static pile frames as pile pressure reaction devices can not only provide a larger pile pressure reaction force, but also is suitable for indoor narrow and low-headroom construction environments. The pile pressure equipment is easy to operate and is a commonly used foundation reinforcement method.

[0004] Although it is convenient to use the anchor static pile frame and reaction beam to provide the pile pressure reaction force, when the pile pressure force is large, the reaction beam will be subjected to excessive bending deformation, which will cause the jack to be dislocated, and the pile pressure cannot continue, and may even cause the anchor pile to be dislocated. At present, the reaction beam is mostly made of steel or steel plate welding. The bending stiffness and deformation resistance of the reaction beam are very important for pile pressure construction. In order to test whether the reaction beam can provide the required pile pressure reaction force, the reaction beam device needs to be sent to a professional testing unit for testing before construction to determine whether its bending stiffness and deformation resistance meet the requirements for pile pressure. The reaction beam detection requires professional equipment, and is limited by the conditions of the testing site, so the test cannot be efficient and convenient.

[0005] Therefore, it is necessary to adopt a device for self-balancing detection of the bearing capacity of the reaction beam, which can quickly and conveniently check the performance of the reaction beam. The device does not require professional testing equipment and is not limited by the conditions of the testing site, thereby improving the detection efficiency of the reaction beam. Summary of the invention

[0006] The purpose of the utility model is to provide a device for self-balancing detection of the bearing capacity of a reaction beam in accordance with the above-mentioned deficiencies of the prior art. Through equipment such as a reaction beam, an anchor rod, a nut and a hydraulic jack, no professional testing equipment is required, and the reaction beam can be directly tested at the construction site to see whether it meets the use requirements of pile driving construction, and the internal structure and size of the reaction beam can be adjusted in time according to the on-site test results.

[0007] The purpose of this utility model is achieved by the following technical solutions:

[0008] A device for self-balancing detection of the bearing capacity of a reaction beam comprises a reaction beam, and is characterized in that the device comprises an anchor rod penetrating between two reaction beams arranged at a certain interval, the anchor rod connects the two reaction beams into an integral structure, and a hydraulic jack is arranged between the two reaction beams arranged at a certain interval.

[0009] Brackets are installed on both sides or corresponding side surfaces of the two reaction beams, and the anchor rods connect the brackets arranged on the two reaction beams into an integral structure.

[0010] The bracket is an L-shaped bracket installed on both sides of the reaction beam, and one side of the L-shaped bracket is welded and fixed to the reaction beam.

[0011] The bracket is a Π-shaped bracket installed on the top or bottom of the reaction beam, one Π-shaped bracket is placed on the top of one reaction beam, and another Π-shaped bracket is placed on the bottom of another reaction beam, and the placement directions of the two Π-shaped brackets are opposite.

[0012] A rib plate is arranged on the inner side of the bracket, and the rib plate is welded and fixed to the bracket.

[0013] The reaction beam is provided with reserved holes, and the anchor rod passes through the corresponding reserved holes provided on the two reaction beams and is then tightened and fixed by a nut.

[0014] The advantages of the utility model are that only simple equipment such as reaction beams, anchor rods, nuts, hydraulic jacks, brackets and ribs are needed to directly test whether the reaction beams meet the requirements for pile driving at the construction site, without being restricted by professional testing equipment and test site conditions. Not only can the number and arrangement of anchor rods be adjusted to meet the requirements for testing reaction beams with different bearing capacities, but it can also be applied to the testing of reaction beams with different cross-sectional forms. The device is convenient in that it can quickly test whether the reaction beam device can provide the pile driving reaction force required for construction at the construction site, and can timely adjust the size and structure of the reaction beam according to the on-site test results to meet the requirements for pile driving construction.

[0021] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0022] like Figure 1-6 As shown, the marks 1-6 in the figure respectively represent: reaction beam 1, hydraulic jack 2, anchor rod 3, nut 4, bracket 5, rib plate 6.

[0023] Embodiment 1: Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the device for self-balancing detection of the bearing capacity of the reaction beam is composed of a reaction beam 1, a hydraulic jack 2, an anchor rod 3 and a nut 4.

[0024] First, complete the installation of the reaction beams 1 on both sides of the device. By passing the anchor rods 3 through the reserved holes on the two reaction beams 1 and then tightening and fixing them with nuts 4, the reaction beams 1 on both sides can be fixed. At this time, the two reaction beams 1 are connected by the anchor rods 3 to form an integral structure. Finally, place the hydraulic jack 2 between the reaction beams 1 on both sides, so that the two sides of the hydraulic jack 2 are respectively attached to the relative surface positions between the reaction beams 1 on both sides, and the installation of the reaction beam bearing capacity self-balancing detection device can be completed. By applying pressure through the hydraulic jack 2, the two reaction beams 1 are simultaneously stressed through the anchor rods 3. When the hydraulic jack 2 is loaded to the test pressure, the pressure of the hydraulic jack 2 is kept stable to the test requirement time. When the bearing capacity and deformation of the reaction beam 1 meet the construction requirements, the pressure can be stopped, and the reaction beam 1 can provide the pile pressure reaction required by the construction.

[0025] In this embodiment, the spacing of the reaction beams 1 can be adjusted according to the size of the jack 2 .

[0026] Embodiment 2: Figure 3 and Figure 5As shown, the difference between this embodiment and the first embodiment is that: when the anchor rod 3 passes through the reaction beam 1, when it is difficult for the anchor rod 3 to pass through the reaction beam 1 or the test reaction force is large and a large number of anchor rods 3 are required, brackets 5 can be installed on both sides of the reaction beams 1 on both sides, and the brackets 5 adopt separate L-shaped brackets. The L-shaped brackets 5 can be welded and fixed firmly with the reaction beams 1 and arranged symmetrically. At the same time, the anchor rod 3 passes through the brackets 5 correspondingly arranged on the reaction beams 1 on both sides, so as to connect the reaction beams 1 on both sides into an integral structure and further ensure the integrity between the two. When the test reaction force is large, ribs 6 can be arranged in the brackets 5, and the ribs 6 are welded and connected to the brackets 5 to increase the structural strength of the brackets 5.

[0027] Embodiment 3: Figure 6 As shown, the difference between this embodiment and the second embodiment is that the structure of the bracket 5 is different. Specifically, the bracket 5 in this embodiment adopts a Π-shaped bracket, which can be directly placed on the top and bottom of the reaction beam 1 and selected according to the test needs. Figure 6 Taking the direction shown as an example, a Π-shaped bracket is arranged at the top of the reaction beam 1 located above, and the opening of the Π-shaped bracket is sleeved on the top periphery of the reaction beam 1 above, and a Π-shaped bracket is arranged at the bottom of the reaction beam 1 located below, and the opening of the Π-shaped bracket is sleeved on the bottom periphery of the reaction beam below, that is, the placement directions of the two Π-shaped brackets are opposite. Afterwards, the two Π-shaped brackets are connected into an integral structure by an anchor rod 3. Similar to the second embodiment, when the test reaction force is large, a rib plate 6 can be arranged in the bracket 5.

[0028] When the above embodiment is implemented: the displacement of the reaction beam 1 on both sides is constrained by the anchor rods 3 and nuts 4, and the reaction beams 1 on both sides are pressurized by the hydraulic jacks 2. When the applied pressure reaches the test set load and a certain test duration is guaranteed, the deformation and stress of the reaction beam 1 are within the required range, and it can be judged that the reaction beam meets the construction use requirements. If the reaction beam 1 is deformed too much during the test, the test can be stopped at any time, the size and structure of the reaction beam 1 can be adjusted, and the test can be repeated. The device only requires simple equipment such as the reaction beam 1, hydraulic jack 2, anchor rods 3, nuts 4, brackets 5 and ribs 6, and can quickly test whether the reaction beam meets the pile driving requirements at the construction site. The operation is simple and not limited by the site. The device can be suitable for reaction beam detection with different bearing capacity requirements and different cross-sectional types by adjusting the number and arrangement of anchor rods.

[0029] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
