Description

Technical Field

[0001] This utility model relates to the technical field of lattice column positioning and installation, and in particular to a lattice column positioning device. Background Technology

[0002] In the field of construction engineering, especially when using the reverse construction method to build deep foundation pits or underground structures, column piles (one pile per column) are key vertical load-bearing components. The lower part is the pile foundation section, which bears the vertical load and transfers it to a deeper, more robust bearing layer. It needs to generate sufficient frictional and end resistance with the surrounding soil / rock, and is often designed with a circular cross-section with a relatively large diameter to ensure sufficient bearing capacity. The upper column frame of the column pile often uses lattice columns, H-shaped steel columns, or steel-concrete composite columns. Lattice columns are typically hollow steel columns with square or rectangular cross-sections, welded together from four angle steel bars and connecting plates. This form is widely used because it saves materials, has good compressive and bending resistance, and the gaps in the middle allow the main beam reinforcement to pass through. In some cases, prefabricated lattice columns need to be inserted into the lower reinforcement cage to a sufficient depth, welded together as a whole, and then hoisted into the drilled pile hole, finally pouring concrete to form permanent support.

[0003] During the "integrated hoisting" process, the heavy "pile-column" composite framework of the columns begins to sink from a suspended state until it is submerged below the ground. The entire process is prone to tilting and instability. Existing devices cannot provide effective and stable constraints throughout this process, causing the lattice columns to sway and deviate. This deviance is difficult to detect and correct in subsequent processes. If the positioning of the lattice columns is off, it will directly prevent the subsequent main beams from smoothly passing through the reserved gaps, seriously affecting structural safety and construction progress. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing devices in the working conditions where the lattice column and the bottom steel cage need to be hoisted as a whole, which cannot provide effective and stable constraints and are prone to causing deviations in the positioning of the lattice column, and to provide a lattice column positioning device.

[0005] This utility model provides a lattice column positioning device, including an orifice support frame, a left positioning frame, and a right positioning frame; the orifice support frame has a main through hole in the middle for the entire cross section of the column to pass through, and several support legs are provided on the periphery of the orifice support frame; the left positioning frame and the right positioning frame are respectively arranged on opposite sides of the orifice support frame, and the left positioning frame and the right positioning frame are rotatably connected to the orifice support frame through a hinge mechanism; the left positioning frame and the right positioning frame are spliced ​​together to form a positioning window for limiting the lattice column.

[0006] Preferably, the orifice support frame includes a basic frame, and the planar shape of the basic frame is square.

[0007] Preferably, the orifice support frame further includes a support beam, which is disposed inside the basic frame and below the left and right positioning frames. The support beam is used to support the left and right positioning frames at the bottom and to achieve the lower limit.

[0008] Preferably, the basic frame is welded from angle steel.

[0009] Preferably, both the left positioning frame and the right positioning frame are constructed using a wire mesh structure.

[0010] Preferably, the left positioning frame and the right positioning frame are arranged symmetrically.

[0011] Preferably, the height of the support leg is adjustable.

[0012] Preferably, the planar shape of the positioning window is rectangular.

[0013] Preferably, the size of the positioning window is adapted to the cross-sectional outline size of the lattice column, and the gap between the two is 10-30mm.

[0014] Preferably, the present invention further includes positioning guard piles and borehole casings. The borehole casings are used for borehole stabilization. Four guard pile positioning points are evenly arranged around the top of the borehole casings in a circumferential direction. The guard pile positioning points and the positioning guard piles are used for guy wire positioning. The borehole support frame is provided with markings around its perimeter for corresponding to the guy wires.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides a lattice column positioning device. By hinged left and right positioning frames on opposite sides of a borehole support frame, it allows a large-section steel cage for the column pile to be lowered through the main through-hole of the borehole support frame when the left and right positioning frames are open. When closed, the lattice column is positioned by a positioning window formed by the splicing of the left and right positioning frames, ensuring the final positioning accuracy of the lattice column. This device is easy to operate, improves the positioning accuracy of lattice columns, and is well-suited for the overall hoisting of the column pile frame. Attached Figure Description

[0028] Example

[0029] like Figures 1-4 As shown, a lattice column positioning device includes an orifice support frame 1, a left positioning frame 2, and a right positioning frame 3. The orifice support frame 1 has a main through hole 101 in the middle for the entire cross-section of the column pile skeleton to pass through. Several support legs 102 are provided on the periphery of the orifice support frame 1. The support legs 102 are used to stably support the entire device on the ground or the top of the orifice casing 6. The left positioning frame 2 and the right positioning frame 3 are respectively set on opposite sides of the orifice support frame 1. The left positioning frame 2 and the right positioning frame 3 are rotatably connected to the orifice support frame 1 through a hinge mechanism 8. The opposite sides of the left positioning frame 2 and the right positioning frame 3 are provided with notches. The two notches are spliced ​​to form a positioning window 4 for limiting the lattice column 5, providing lateral constraint for the lattice column 5.

[0030] The shape of the positioning window 4 may or may not match the cross-sectional shape of the lattice column 5. For example, the planar shape of the positioning window 4 can be a regular or irregular shape such as a circle, and it is approximately tangent to the rectangular cross-section of the lattice column 5. Preferably, the planar shape of the positioning window 4 is rectangular, which better matches the lattice column 5, and the structure is simple and easy to process.

[0031] In an optional embodiment, the size of the positioning window 4 is adapted to the cross-sectional outline size of the lattice column 5, and the gap between the two is 10-30mm.

[0032] In an optional embodiment, a detachable guide bushing is provided around the periphery of the positioning window 4 to increase the constraint length of the positioning window 4, thereby achieving guidance and alignment. The guide bushing may be composed of two grooved steel plates, or angle steel may be used and set at the four corners of the positioning window 4, and is not limited to the examples mentioned above.

[0033] In an optional embodiment, the hinge mechanism 8 includes a hinge lug disposed inside or on top of the orifice support frame 1 and a hinge shaft passing through the hinge lug.

[0034] In an optional embodiment, the orifice support frame 1 includes a basic frame, the basic frame having a square-shaped planar shape and being welded from angle steel.

[0035] Furthermore, in an optional embodiment, the orifice support frame 1 may also include a support beam. The support beam is located inside the basic frame and below the left positioning frame 2 and the right positioning frame 3. The support beam is used to support the left positioning frame 2 and the right positioning frame 3 at the bottom, facilitating transfer and transportation, and can also play a certain lower limiting role, reducing the concentrated stress at the hinge mechanism 8. The support beam can be inclined at the four corners, or it can be set longitudinally or laterally on opposite sides of the basic frame.

[0036] In an optional implementation, both the left positioning frame 2 and the right positioning frame 3 are constructed with wire mesh, which can prevent people and tools from accidentally falling into the opening and improve construction safety.

[0037] In an optional embodiment, the left positioning frame 2 and the right positioning frame 3 are symmetrically arranged. This ensures that the seam between the left positioning frame 2 and the right positioning frame 3 is straight and located in the center of the positioning window 4, facilitating opening and closing and simplifying processing.

[0038] As another possible implementation method, the butt joint can also be in the form of a wave shape or multiple zigzag lines.

[0039] In an optional embodiment, the height of the support leg 102 is adjustable to accommodate different burial depths and ground elevation differences, enhancing the versatility and adaptability of the structure. Preferably, the support leg 102 can be fixed with bolts.

[0040] Furthermore, in one or more embodiments, such as Figure 1 As shown, the above-mentioned lattice column positioning device also includes positioning guard piles 7 and orifice casings 6. The orifice casing 6 is used for orifice stabilization. Four guard pile positioning points are evenly arranged circumferentially on the top of the orifice casing 6. These positioning points, along with the positioning guard piles 7, are used for guy line positioning. Marks corresponding to the guy lines are provided around the orifice support frame 1. The guard pile positioning points can be crosshair grooves, through holes, or protruding centering pins, etc. The splicing size of the square positioning window 4 is smaller than the inner wall diameter of the orifice casing 6.

[0041] The center of the orifice casing 6 is located by pulling a vertical line, and then the vertical line is aligned with the marks around the orifice support frame 1. This ensures that the center of the positioning window 4 in the middle of the orifice support frame 1 is aligned with the center of the orifice casing 6 when the orifice support frame 1 is installed, so as to achieve the calibration and installation of the lattice column positioning device.

[0042] In an optional embodiment, the orifice support frame 1 can be an integral structure or a split structure, consisting of two steel frames combined and fixed.

[0043] The workflow for constructing column piles using the aforementioned lattice column positioning device is as follows:

[0044] Before hoisting the lattice column 5, the positioning device is first installed at the pile hole opening. It is then precisely leveled and centered using a spirit level and positioning guard pile 7. After adjusting the positioning device to its accurate position, fixing bolts are arranged along the pre-drilled bolt holes on the perimeter and inserted into the ground to fix the hole opening support frame 1. At this time, the left positioning frame 2 and right positioning frame 3 on both sides are in the open state. A crane is used to lift the column pile skeleton composite, allowing it to slowly approach the positioning device from above. The lower steel cage section of the column pile skeleton first passes through the main through hole 101 of the hole opening positioning frame. When the lattice column 5 sinks to the hole opening position, the hoisting is paused. The operators close the left positioning frame 2 and right positioning frame 3 on both sides, clamping them around the lattice column 5 to correct its position during hoisting. Under the strong constraint of the hole opening support frame 1 and positioning window 4, the lattice column 5 maintains a high degree of verticality and sinks smoothly to the design elevation. Finally, pour the concrete. After it has initially set, the left positioning frame 2 and the right positioning frame 3 can be opened again, the positioning device can be removed as a whole, and it can be reused.

[0045] This embodiment uses a left positioning frame 2 and a right positioning frame 3 hinged to opposite sides of the orifice support frame 1. When the left and right positioning frames 2 and 3 are open, a steel cage with a large cross-section for the column pile can be lowered through the main through-hole 101 of the orifice support frame 1. When closed, the positioning window 4 formed by the splicing between the left and right positioning frames 2 and 3 limits the positioning of the lattice column 5, reducing installation deviations, especially at the lattice column 5, ensuring final positioning accuracy, and thus avoiding the risk of the main beam being unable to pass through. This device is easy to operate, improves the positioning accuracy of the lattice column 5, and has good adaptability to the overall hoisting of the column pile skeleton.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
