Description

Technical Field

[0001] This utility model relates to the field of reference beam support technology, specifically to a foldable static load test reference beam support. Background Technology

[0002] The reference beam is a component used to provide a measurement benchmark in the static load test of pile foundation. In the existing technology, the method of erecting the reference beam in the static load test of pile foundation is relatively arbitrary. The temporary support used to erect the reference beam often cannot guarantee the erection stability of the reference beam in terms of stiffness, strength and stability. As a result, the erection stability of the reference beam cannot meet the requirements of the test specifications, and the collected data is easily affected and deviates.

[0003] A search revealed that Chinese Patent (Publication No.: CN204898746U) discloses "a support for erecting a reference beam in a static load test of a pile foundation, comprising: a vertical support rod and a sliding support seat disposed on the vertical support rod, the sliding support seat comprising a cylindrical part for fitting onto the vertical support rod and a support part for installing the reference beam, the support part comprising a vertical side wall parallel to the axis of the cylindrical part and a horizontal bottom wall perpendicular to the axis of the cylindrical part, the bottom of the vertical side wall being connected to the bottom of the cylindrical part through the horizontal bottom wall."

[0004] However, in the process of implementing the relevant technologies, the aforementioned patents have some technical defects:

[0005] First, the materials and connection methods of the temporary supports used in the existing technology (such as loose bolts or weak welds) are prone to causing insufficient overall structural rigidity. Under test loads or environmental disturbances (such as wind and vibration), micro-deformation occurs, which causes the reference beam to shift and affects the authenticity of the measurement data.

[0006] Secondly, the bottom support members of the bracket lack a synchronous adjustment mechanism, and the height or angle of each support point needs to be adjusted separately, making it difficult to ensure that multiple members are subjected to force in a coordinated manner, which can easily cause the reference beam to tilt or settle. When the ground is uneven, the existing bracket cannot quickly adapt to height changes and requires pads or additional reinforcement, which increases the complexity of installation and the risk of human error.

[0007] In view of this, the present invention proposes a foldable static load test reference beam support. Utility Model Content

[0008] This invention proposes a foldable static load test reference beam support, which solves the problem of poor stability caused by insufficient overall structural stiffness in the prior art.

[0009] The technical solution of this utility model is as follows: A foldable static load test reference beam support includes a base. The bottom of the base is provided with a plurality of support rods distributed at equal angles around the base. Each support rod includes a sleeve hinged to the bottom of the base. One end of the sleeve is inserted with a rod. A locking bolt that is threadedly connected to the outside of the sleeve is rotatably connected to the rod. An adjustment mechanism for driving the plurality of sleeves to move synchronously in opposite directions or in opposite directions is provided at the center of the bottom of the base. A plurality of storage parts for storing the sleeves are provided on the outer edge of the bottom of the base.

[0010] Preferably, the outer side of the insertion rod is provided with a plurality of screw holes evenly distributed along the axial direction, and the locking bolt is threadedly engaged with any one of the screw holes.

[0011] Preferably, the adjusting mechanism includes a fixed cylinder fixedly connected to the bottom of the base, a movable seat movably connected to the inner side of the fixed cylinder, and a plurality of connecting seats corresponding one-to-one with the sleeves fixedly connected to the outer side of the movable seat. The plurality of connecting seats are slidably connected to the fixed cylinder, and a connecting rod is hinged to one end of each of the plurality of connecting seats. The end of each of the plurality of connecting rods away from the connecting seat is hinged to the corresponding sleeve.

[0012] Preferably, the adjusting mechanism further includes a lead screw rotatably connected to the inside of the fixed cylinder, the lead screw being threadedly connected to the movable seat, and a handwheel being fixedly connected to the bottom of the lead screw.

[0013] Preferably, the storage component includes a fixed base fixedly connected to the bottom of the base, and the bottom of the fixed base is fixedly connected to a retaining seat that slides with the sleeve.

[0014] Preferably, the bottom end of the card holder is provided with a through hole, and a positioning rod that passes through the through hole is slidably connected to the inner side of the through hole.

[0015] Preferably, the outer wall of the sleeve is provided with a positioning hole, and one end of the positioning rod is slidably engaged with the positioning hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Multiple support rods are arranged around the bottom of the base, and a sleeve and plug-in structure is used. Combined with the threaded engagement of locking bolts and screw holes, the mechanical self-locking capability and load-bearing stability of the bracket are effectively improved. This design avoids the micro-deformation problem caused by loose bolts or weak welds in existing technologies, ensuring that the benchmark beam remains stable under test loads or environmental disturbances (such as wind and vibration), thereby guaranteeing the authenticity of the measurement data.

[0018] 2. The adjustment mechanism, through the linkage design of lead screws, movable seats, connecting seats, and connecting rods, enables the synchronous expansion or contraction of all support rods. This mechanism solves the problem of needing to adjust the height or angle of support points individually in existing technologies, ensuring that multiple rods work together to bear the force, avoiding tilting or settlement of the reference beam, while also adapting to the need for rapid adjustment on uneven ground, reducing human error and installation complexity.

[0019] 3. The insert rod in the support member can slide axially along the sleeve and is fixed to the screw holes at different positions by locking bolts, achieving flexible height adjustment. This design is suitable for different ground conditions and reference beam installation requirements, while mechanical self-locking prevents slippage under load, significantly improving operational efficiency and adaptability.

Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1 to 5 As shown, this embodiment proposes a foldable static load test reference beam support, including a base 1. The bottom of the base 1 is provided with several support rods 2 that are equally distributed around the base 1. Each support rod 2 includes a sleeve 21 hinged to the bottom of the base 1. One end of the sleeve 21 is inserted with a rod 22. The outer side of the sleeve 21 is rotatably connected with a locking bolt 23 that is threaded to the rod 22. The outer side of the rod 22 is provided with several screw holes 24 that are equally distributed along the axial direction. The locking bolt 23 is threaded to any one of the screw holes 24. An adjustment mechanism 3 is provided at the center of the bottom of the base 1 to drive the sleeves 21 to move synchronously in opposite directions or in opposite directions. Several storage parts 4 are provided on the outer edge of the bottom of the base 1 to store the sleeves 21.

[0029] In this embodiment, during installation, the insertion rod 22 can slide freely inside the sleeve 21 by loosening the locking bolt 23, thereby adjusting the length of the support rod 2. After determining the length, the extension length of the insertion rod 22 can be fixed by rotating the locking bolt 23 and the thread engagement of the corresponding screw hole 24. This allows for length adjustment of the support rod 2 to adapt to different ground heights and the installation requirements of the reference beam. The thread engagement of the locking bolt 23 and the screw hole 24 provides mechanical self-locking capability to prevent the insertion rod 22 from sliding under load and ensure support stability.

[0030] In a further preferred embodiment of the present invention, the adjusting mechanism 3 includes a fixed cylinder 31 fixedly connected to the bottom of the base 1, a movable seat 33 movably connected to the inner side of the fixed cylinder 31, and a plurality of connecting seats 34 corresponding one-to-one with the sleeve 21 fixedly connected to the outer side of the movable seat 33. The plurality of connecting seats 34 are slidably connected to the fixed cylinder 31, and a connecting rod 35 is hinged to one end of each of the plurality of connecting seats 34. The end of the plurality of connecting rods 35 away from the connecting seat 34 is hinged to the corresponding sleeve 21. A lead screw 32 is rotatably connected to the inner side of the fixed cylinder 31. The lead screw 32 is threadedly connected to the movable seat 33, and a handwheel 36 is fixedly connected to the bottom of the lead screw 32.

[0031] In this embodiment, the handwheel 36 drives the lead screw 32 to rotate, which in turn pushes the movable seat 33 to move axially along the fixed cylinder 31. The movable seat 33 drives all the sleeves 21 to rotate synchronously around the hinge point of the base 1 through the hinged connecting rod 35, thereby realizing the unfolding, folding or retracting of the support rod 2, which facilitates the storage and transportation of the overall bracket.

[0032] In a further preferred embodiment of the present invention, the storage component 4 includes a fixed base 41 fixedly connected to the bottom of the base 1. The bottom of the fixed base 41 is fixedly connected to a retaining seat 42 that slides with the sleeve 21. The bottom end of the retaining seat 42 is provided with a through hole 44. A positioning rod 43 that passes through the through hole 44 is slidably connected to the inner side of the through hole 44. The outer wall of the sleeve 21 is provided with a positioning hole 25. One end of the positioning rod 43 slides with the positioning hole 25.

[0033] In this embodiment, when the sleeve 21 is unfolded to a horizontal state, it is embedded inside the card holder 42, and by pushing the positioning rod 43, one end of it is inserted into the positioning hole 25 on the outer wall of the sleeve 21 to achieve mechanical locking, thus realizing the storage of the sleeve 21, thereby facilitating the storage and transportation of the entire bracket.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
