Description

Technical Field

[0001] The utility model belongs to the technical field of construction pile foundation construction devices, and particularly relates to a lattice column sliding positioning auxiliary device. Background Art

[0002] In the construction of deep foundation pit building projects, lattice steel columns are widely used as support designs due to their convenient installation and disassembly and high recycling rate. These steel columns play a crucial role in key parts such as concrete support trestles and tower crane foundations in the underground structure stage. However, there are some obvious limitations in the hoisting process of lattice columns in the prior art: the difference between the aperture of the pile driver hoisting hole platform and the size of the lattice column, combined with the lack of effective fixing measures and precise construction methods, often leads to irreversible position deviation of the lattice column during installation. This deviation is not only difficult to adjust in the later stage, but may also have a serious impact on the stability and safety of the entire structure; according to the inspection statistics of multiple projects, the deviation of the lattice column hoisting position from the design coordinate may even exceed 150 mm under the traditional method. In today's increasingly high engineering precision requirements, especially when the load-bearing requirements of the upper building are significantly increased, there are obviously potential safety hazards.

[0003] Specifically, in the traditional construction method of lowering the lattice column into the hole of the pile driver hoisting hole platform by the traction of the pile driver at the pile driver hoisting hole platform, due to the lack of automated or semi-automated auxiliary positioning tools, construction workers have to make repeated manual adjustments. And during the adjustment process of the lattice column position, it completely depends on manual adjustment and visual inspection, which not only increases the labor intensity, but also prolongs the project cycle, resulting in low construction efficiency and difficult to ensure construction precision; in addition, a large initial deviation often requires subsequent re-hoisting or adjustment, which not only causes waste of manpower and material resources, but also increases the construction cost; more seriously, the existence of position deviation may cause uneven structural stress, increasing potential safety hazards during the construction process and affecting the quality and reputation of the entire project.

[0004] After retrieval, the existing Chinese invention document with the publication number CN113562629B discloses a lattice column positioning and plumbness adjustment system, "including a crane, and also including an upright frame. A horizontal crossbeam is provided at the top of the upright frame, and the crane is installed on the crossbeam. A traction rope is connected to the crane hook, and a clamp for clamping the lattice column is provided at the end of the traction rope. A positioning sleeve for inserting the lattice column is provided on the side wall of the upright frame, and electric cylinders corresponding to each edge of the lattice column are provided on the side wall of the positioning sleeve. The driving rods of each electric cylinder penetrate into the positioning sleeve, and the penetrated ends are all rotatably connected with positioning wheels. A sinking groove matched with the edge of the lattice column is opened on the peripheral wall of the positioning wheel." Although this invention has the effect of improving the bearing capacity of the lattice column, its structure is complex and its own volume is large, resulting in difficult disassembly and assembly and more construction site occupation after installation. Moreover, only diagonal clamping still cannot effectively ensure the positioning accuracy of the lattice column, and deviation will occur during the adjustment process, which has certain limitations.

[0005] Therefore, there is an urgent need for a new positioning auxiliary device to solve this problem, so as to improve the construction efficiency and ensure the project quality and safety. Utility Model Content

Through this device, construction workers can select an appropriate number of devices according to actual needs and quickly remove them after the operation is completed for reuse in other projects. The installation and removal process of the device is simple and fast, and its own strength is high, which can effectively reduce the position deviation during the lattice column hoisting process and reduce the error caused by manual adjustment. In addition, the application of this device helps to reduce resource waste and improve construction safety, providing a more efficient, safe, and reliable construction method for the deep foundation pit construction of building projects.

[0026] Example 1

[0027] As Figure 1 and Figure 2 shown, this embodiment provides a lattice column sliding positioning auxiliary device, which is applicable to fixed-point limit during the hoisting process of the lattice column 5. The device includes a number of bodies 1, and each body 1 includes a fixed beam 2, a hydraulic jack 3 and a rotating end 4. The rotating end 4 is movably connected to the fixed beam 2 through the hydraulic jack 3. The rotating end 4 is provided with a positioning coordinate measurement point 42 and a positioning pulley 41. The number of the bodies 1 is not less than two, and at least two of the bodies 1 are arranged diagonally on the pile driver hoisting hole platform 6. The device clamps and fixes the lattice column 5 through the oppositely arranged positioning pulleys 41.

[0028] The fixed beam 2 is in the shape of an isosceles right triangle. A number of tie holes 21 are opened on the fixed beam 2, and the tie holes 21 are located at the vertex positions on the fixed beam 2. The tie holes 21 are equipped with positioning bars with diameters slightly smaller than those of the tie holes 21. The positioning bars are welded to the pile driver hoisting hole platform 6, and the fixing positions of the positioning bars correspond to the positions of the tie holes 21. The fixed beam 2 is fixed to the upper end surface of the pile driver hoisting hole platform 6 through the tie holes 21 and the positioning bars, so that a tensile force is generated between the fixed beam 2 and the pile driver hoisting hole platform 6. The fixed beam 2 further includes a strengthening beam 24, and the strengthening beam 24 is located on the perpendicular bisector of the inner hypotenuse of the fixed beam 2. The two ends of the strengthening beam 24 are respectively fixed to the midpoint of the hypotenuse of the fixed beam 2 and the right-angled vertex of the fixed beam 2. Auxiliary installation holes 23 are also provided on the fixed beam 2. The auxiliary installation holes 23 are evenly distributed on the fixed beam 2 and are located between adjacent tie holes 21 of the same device. The auxiliary installation holes 23 are equipped with fasteners. By installing fasteners in the auxiliary installation holes 23, the stability between the fixed beam 2 and the pile driver hoisting hole platform 6 is further improved. In this embodiment, the fixed beam 2 is made of square steel with a size of 100mm * 100mm * 6mm.

[0029] The hydraulic jack 3 is vertically fixed at the midpoint position on the outer side surface of the hypotenuse of the fixed beam 2. The hydraulic jack 3 includes a hydraulic cylinder 31, a hydraulic jack rod 32 and an operating rod 33. The hydraulic jack rod 32 is arranged in the hydraulic cylinder 31, and the operating rod 33 is used to control the telescopic movement of the hydraulic jack rod 32 along the axis direction of the hydraulic cylinder 31, and the operating rod 33 is arranged on the side wall of the hydraulic cylinder 31. The working principle of the hydraulic jack 3 is the same as that of a manual hydraulic jack. In actual work, by manually adjusting the operating rod 33, the hydraulic jack 3 can be used to drive the rotating end 4 to laterally push the lattice column 5 in a suspended state, so as to change the position of the lattice column 5.

[0030] A rotating end 4 is movably connected to the top end of the hydraulic ejector rod 32. The rotating end 4 can rotate 360° along the central axis of the hydraulic ejector rod 32. Moreover, a braking knob 321 is provided on the side wall of the hydraulic ejector rod 32. The braking knob 321 is used to adjust the movement damping of the rotating end 4, so as to lock and fix the rotating end 4 on the hydraulic ejector rod 32. A positioning pulley 41 is fixed to the top end of the rotating end 4 through a pin. A counterbore 411 for embedding any one of the four corners of the lattice column 5 is provided on the circumferential side of the positioning pulley 41. In this embodiment, the width of the positioning pulley 41 is 20 mm, and the cross-sectional shape of the counterbore 411 is a right triangle, which can effectively catch any one of the four corners of the lattice column 5. A positioning coordinate measurement point 42 and a level bubble 43 are provided on the upper end surface of the rotating end 4 for coordinate measurement and levelness inspection. The central axes of the positioning coordinate measurement point 42 and the level bubble 43 are both on the same horizontal plane. In this embodiment, the fixed distance between the positioning coordinate measurement point 42 and the lowest point of the outer counterbore 411 of the positioning pulley 41 is 100 mm. In actual work, by measuring the coordinates of the positioning coordinate measurement point 42, the actual coordinates of the contact point between the lattice column 5 and the positioning pulley 41 can be calculated and deduced, effectively solving the problem of difficult measurement of the actual coordinates of the lattice column 5. Moreover, further, by comparing the actual coordinates with the designed coordinates, it can be checked whether there is a deviation in the position of the lattice column 5. A point groove is provided at the position where the positioning coordinate measurement point 42 is located, and paint is applied in the point groove, so that the positioning coordinate measurement point 42 is more eye-catching, which is beneficial to improving the coordinate accuracy of the positioning coordinate measurement point 42 obtained by measurement.

[0031] Embodiment 2

[0032] As Figure 3 and Figure 4 shown, this embodiment provides a positioning method for the lattice column sliding positioning auxiliary device using Embodiment 1, including the following steps:

[0033] S1. Install this device on the pile driver hoisting hole platform 6: According to the positions of the tie holes 21 on this device on the pile driver hoisting hole platform 6, weld a positioning bar at the corresponding positions respectively. The diameter of the positioning bar is 25 mm. Then, pass the tie holes 21 through the positioning bars, so that this device is clamped and fixed on the pile driver hoisting hole platform 6. In another embodiment, when the auxiliary installation holes 23 are further provided on the fixed beam 2, after this device is fixed to the pile driver hoisting hole platform 6 through the tie holes 21 and the positioning bars, drill fixing holes in the auxiliary installation holes 23 towards the pile driver hoisting hole platform 6, and sequentially pass fasteners through the auxiliary installation holes 23 and the fixing holes and tighten them to further improve the stability between the fixed beam 2 and the pile driver hoisting hole platform 6.

[0034] S2. Adjust the hydraulic rod 32 of the hydraulic jack 3 through the operating rod 33 to fix the lattice column 5: During the process of lowering the lattice column 5 into the hole of the pile driver hoisting hole table 6, first use the pile driver 7 to ensure that the lattice column 5 is in a suspended state for subsequent positioning operations (specifically, refer to the elevation view of the device installation). Then, when the lattice column 5 is in a suspended state, adjust the telescopic length of the hydraulic rod 32 through the operating rod 33 so that the positioning pulley 41 at the top can accurately catch the diagonal of the lattice column 5, and further adjust the length of the hydraulic rod 32 to laterally push the suspended lattice column 5 to make the lattice column 5 return to the correct design coordinates. In another embodiment, four-corner fasteners can be set to enhance stability and positioning accuracy.

[0035] S3. After leveling, positioning and fixing the rotating end 4, check the position deviation of the lattice column 5 through coordinate measurement: Adjust the rotating end 4 of the fastener, use the level bubble instrument 43 for auxiliary leveling, and ensure that the rotating end 4 is in a horizontal state by observing the position of the level bubble in the level bubble instrument 43, so as to ensure the verticality of the lattice column 5. When the rotating end 4 is adjusted to a horizontal balance state, lock and fix the rotating end 4 through the brake knob 321 to prevent deviation during hoisting.

[0036] S4. After the rotating end 4 is fixed, conduct a review of the horizontal position coordinates: Use a total station to measure the actual coordinates of the two diagonal points of the lattice column 5 through the positioning coordinate measurement point 42 to ensure that the actual coordinates of the lattice column 5 in the vertical state meet the design coordinate requirements. If the measurement result does not meet the design coordinate requirements, the above adjustment steps need to be repeated until the position of the lattice column 5 meets the design specifications. In another embodiment, a body 1 is installed at each of the four corners of the pile driver hoisting hole table 6, so that by sequentially measuring the positioning coordinate measurement points 42 on each body 1, the four-corner coordinates of the lattice column 5 can be calculated and derived, further improving the positioning accuracy.

[0037] S5. When the position of the lattice column 5 is adjusted to meet the design coordinate requirements, that is, the positioning of the lattice column 5 is completed. At this time, the positioning pulley 41 can assist in lowering the lattice column 5 to the predetermined bottom elevation position.

[0038] The lattice column 5 sliding positioning auxiliary device of the present utility model can effectively achieve precise positioning and limiting of the lattice column 5 during hoisting through the above steps. At the same time, when the length of the lattice column 5 is insufficient, the device can assist in the lengthening operation of the lattice column 5 during the hoisting process of the lattice column 5 to adapt to lattice columns 5 of different lengths. By providing solutions for the positioning and length lengthening of the lattice column 5, different construction requirements are met.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any changes or equivalent replacements of these features and embodiments can be made by those skilled in the art without departing from the spirit and scope of the present utility model. Additionally, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
