Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of housing municipal engineering, and in particular relates to a prestressed pipe pile hammering construction auxiliary device. Background Art
[0002] Prestressed pipe piles are widely used in the field of construction engineering, with the advantages of fast construction, mature and reliable technology, etc. The construction methods include static pressure method and hammer method. The former requires a large investment in equipment procurement and has strict requirements on site conditions, while the latter has lighter machinery, less investment, and low requirements on site conditions, so it is widely used. At present, when the hammer is closed during the construction stage, for the last three rounds of hammering, the on-site workers simply use a steel bar to mark the pile body, and simply step on the lower end to fix it. Therefore, the lower end fixing point may move, resulting in distortion of the hammer closing process, and the pipe pile does not enter the bearing layer deep enough, causing major structural quality and safety hazards. Utility Model Content
[0003] The purpose of the present invention is to provide a prestressed pipe pile hammer construction auxiliary device, which can solve the above technical problems.

[0006] A fixing portion, disposed on the lower surface of the mounting seat and used for inserting into the ground to fix the mounting seat to the ground;
[0007] The marking steel bar has a first end and a second end for marking, wherein the first end is movably mounted on the upper surface of the mounting seat through a connecting structure so that the second end can rotate around a vertical axis to achieve marking.
[0008] Optionally, the connection structure includes a first connection ring and a second connection ring; the first connection ring is fixedly connected to the upper surface of the mounting seat; the second connection ring is fixedly connected to the first end of the marked steel bar;
[0009] Wherein, the first connecting ring passes through the inner hole of the second connecting ring, and the second connecting ring passes through the inner hole of the first connecting ring.

[0015] Optionally, the second connecting ring is welded and fixed to the first end of the marked steel bar.
[0016] Optionally, the fixing portion is cylindrical.
[0017] The main technical effect achieved by the embodiments of the present disclosure is that during the use of the auxiliary device in this patent, the fixing part is first inserted into the ground to fix the mounting base to the ground, thereby effectively restraining the lower part of the marked steel bar, ensuring that the lower end is fixed during the marking process, and can effectively reflect the pile sinking process; and when the marking is completed at one pile position, the auxiliary device can be taken out and reused at the next pile position, with small economic investment, simple operation and obvious benefits.

[0024] like Figure 1-3 As shown, the prestressed pipe pile hammer construction auxiliary device includes a mounting seat 1, a fixing portion 5 and a marking steel bar 2.
[0025] The mounting base 1 has an upper surface and a lower surface that are arranged opposite to each other. Specifically, the mounting base 1 in the present disclosure is a thin steel plate, which can be found everywhere on the construction site and is easy to obtain. Of course, in other embodiments, the mounting base 1 can also be other structures, and the present disclosure does not limit this.
[0026] The fixing part 5 is arranged on the lower surface of the mounting base 1 and is used to be inserted into the ground to fix the mounting base 1 to the ground; the fixing part 5 in the present disclosure is provided with a plurality of fixing parts 5 to ensure that the mounting base 1 can be firmly fixed to the ground. Specifically, the fixing part 5 in the present disclosure can be cylindrical or conical, so that the fixing part 5 can be inserted into the ground more labor-savingly. Of course, in other embodiments, the fixing part 5 can also be other structures, and the present disclosure is not limited to this.
[0027] The marking steel bar 2 has a first end and a second end for marking. The first end is movably mounted on the upper surface of the mounting base 1 through a connecting structure so that the marking steel bar 2 can rotate in space around the first connecting ring 3, thereby marking the second end, while allowing the distance between the auxiliary device and the pipe pile to vary in a small range (different inclination angles of the marking steel bar).
[0028] During use of the auxiliary device disclosed in the present invention, the fixing part 5 is first inserted into the ground to fix the mounting base 1 to the ground, thereby effectively restraining the lower part of the marking steel bar 2 to ensure that the marking can effectively reflect the pile sinking process; and when the marking is completed at one position, the auxiliary device can be taken out and reused in the next one, with small economic investment, simple operation and obvious benefits.
[0029] As an optional embodiment, the connection structure includes a first connection ring 3 and a second connection ring 4; the first connection ring 3 is fixedly connected to the upper surface of the mounting seat 1; the second connection ring 4 is fixedly connected to the first end of the marking steel bar 2; wherein the first connection ring 3 passes through the inner hole of the second connection ring 4, and the second connection ring 4 passes through the inner hole of the first connection ring 3. Through such a configuration, the marking steel bar 2 can be rotated in the horizontal circumferential direction through the rotation of the second connection ring 4 itself to achieve marking; on the other hand, the second connection ring 4 can be rotated around the first connection ring 3 to rotate in the vertical circumferential direction, thereby adjusting the marking height of the marking steel bar 2.
[0030] As an optional implementation, the first connecting ring 3 is welded and fixed to the mounting seat 1. The second connecting ring 4 is welded and fixed to the first end of the marking steel bar 2. With such an arrangement, the structure is stable and easy to implement.
[0031] As an optional embodiment, the diameter of the first connecting ring 3 is equal to the diameter of the inner hole of the second connecting ring 4. By such a configuration, shaking of the marked steel bar 2 during horizontal rotation is avoided, the stability of the horizontal rotation of the marked steel bar 2 is ensured, and the accuracy of the marking of the marked steel bar 2 is ensured.
[0032] As an optional embodiment, the diameter of the second connecting ring 4 is equal to the diameter of the inner hole of the first connecting ring 3. By such a configuration, shaking of the marked steel bar 2 during vertical rotation is avoided, the stability of the vertical rotation of the marked steel bar 2 is ensured, and the accuracy of marking of the marked steel bar 2 is ensured.
[0033] It should be noted that the diameter of the first connecting ring 3 refers to the diameter of the first connecting arms forming the first connecting ring 3 ; the diameter of the second connecting ring 4 refers to the diameter of the second connecting arms forming the second connecting ring 4 .
[0034] As an optional embodiment, the axis direction of the first connecting ring 3 is arranged horizontally. By so arranging, the marked steel bar 2 can be free from horizontal displacement when rotating vertically, thereby ensuring faster rotation in the vertical direction.
[0035] As an optional embodiment, the axial direction of the second connecting ring 4 is perpendicular to the axial direction of the marking steel bar 2. This arrangement ensures that when the marking steel bar 2 rotates vertically, there is no torque interference between the marking steel bar 2 and the mounting seat 1, thereby ensuring smooth rotation of the marking steel bar 2.
[0036] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
