Description

Technical Field

[0001] This application relates to the field of underground engineering construction technology, specifically to a lattice column positioning component and device. Background Technology

[0002] In underground engineering construction, to ensure the safety and stability of the foundation pit formed by excavation from the ground during the construction of underground structures, a support system is typically used to protect the sidewalls of the pit and the surrounding environment, preventing the displacement of the soil within the pit. The column piles are the vertical load-bearing structure of the support system, mainly composed of steel lattice columns welded together with cast-in-place pile reinforcement cages. The installation quality of the column piles is crucial to ensuring the quality and stability of the support system.

[0003] The traditional construction process for foundation pit column piles is as follows: First, mechanical drilling is used to create the bored pile portion of the column pile. Once the designed hole depth is reached and the hole is cleaned, a lifting device is used to hoist the reinforcing cage for the column pile. The lattice column is then fixed to the top of the reinforcing cage by welding, and lowered to the designed elevation within the hole. Finally, the orientation of the lattice column is adjusted manually by rotation. This construction method relies on manual rotation to adjust the orientation of the lattice column, which is not only difficult and inefficient, but also frequently results in significant deviations between the orientation of the lattice column and the design drawings. These deviations not only affect the connection between the lattice column and the supporting beams, but also cause uneven stress on the structure, impacting the stress and safety of the support system.

[0004] To address these issues, lattice column positioning components are currently installed at the borehole opening to position the lattice columns circumferentially, preventing changes in their orientation during lowering and ensuring that the post-construction orientation meets design requirements. However, existing lattice column positioning components are complex in structure and bulky in size. They not only require dedicated platforms, increasing construction complexity and difficulty, but also have high environmental requirements, rendering them ineffective in areas with limited space, complex environments, or insufficient load-bearing capacity, such as valleys and rivers. Utility Model Content

[0005] The purpose of this application is to provide a lattice column positioning component and device to solve the problem that existing positioning components require a dedicated platform.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0007] In a first aspect, a lattice column positioning assembly is provided, including a mounting base for mounting on the top of a steel casing, a fixing rod extending downward on one side of the mounting base, a support block located below the mounting base on the side of the fixing rod facing the mounting base, a positioning seat on the lower end of the side of the fixing rod away from the mounting base, and a lattice column positioning groove on the side of the positioning seat away from the fixing rod.

[0008] Furthermore, the mounting base includes an overlapping rod for supporting the top of the steel casing and a limiting block provided at the bottom of the overlapping rod. One end of the overlapping rod is connected to the upper end of the fixing rod, and a receiving groove for accommodating the top of the steel casing is formed between the overlapping rod, the limiting block and the fixing rod.

[0009] Furthermore, the limiting block is connected to the overlapping rod through a first adjusting mechanism, which is used to adjust the distance between the limiting block and the fixed rod.

[0010] Furthermore, the first adjustment mechanism includes a hand crank.

[0011] Furthermore, the support block is connected to the fixed rod via a second adjustment mechanism, which is used to adjust the distance between the support block and the fixed rod.

[0012] Furthermore, the second adjustment mechanism is located at the bottom of the positioning seat.

[0013] Furthermore, the second adjustment mechanism includes an electric push rod.

[0014] Furthermore, the positioning seat includes a connecting rod and two positioning rods. One end of the connecting rod is connected to the lower end of the fixing rod, and the other end of the connecting rod is connected to one end of the two positioning rods. The other ends of the two positioning rods are far apart from each other and form the lattice column positioning groove between them.

[0015] Furthermore, the fixing rod, the connecting rod, and the two positioning rods are integrally formed.

[0016] In a second aspect, a lattice column positioning device is provided, comprising a steel casing and four positioning components evenly distributed along the circumference of the steel casing, wherein the positioning components are the lattice column positioning components provided in the first aspect.

[0017] The mounting base is installed on the top of the steel casing, the fixing rod is located inside the steel casing, the support block is supported on the inner wall of the steel casing, and the four lattice column positioning slots form a lattice column positioning cavity.

[0018] The beneficial effects of this application are:

[0019] 1. The lattice column positioning component and device provided in this application embodiment can circumferentially position the lattice column by installing the positioning component on the top of the steel casing and using the lattice column positioning groove on the positioning seat. This avoids changes in the orientation of the lattice column during the lowering process, ensuring that the orientation of the lattice column after construction meets the design requirements. This avoids the errors and uncertainties caused by manually rotating and adjusting the orientation of the lattice column in traditional construction.

[0020] 2. The lattice column positioning component of this application has a relatively simple structure and small size. It can be directly installed on the top of the steel casing and uses the steel casing as a supporting foundation. There is no need to set up a special platform, which reduces the complexity and difficulty of construction. It has low requirements for the bearing capacity and space of the construction site. It can function normally in areas with limited space or in complex environments such as valleys and rivers. This good environmental adaptability makes it widely applicable in various underground engineering construction scenarios, effectively solving the problem of limited function of existing positioning components in special environments.

[0042] See Figure 1 This application provides a lattice column positioning assembly, including a mounting base 21 for mounting on the top of a steel casing 1. A fixing rod 22 extending downward is provided on one side of the mounting base 21. A support block 23 located below the mounting base 21 is provided on the side of the fixing rod 22 facing the mounting base 21. A positioning seat 24 is provided at the lower end of the side of the fixing rod 22 away from the mounting base 21. A lattice column positioning groove 241 is provided on the side of the positioning seat 24 away from the fixing rod 22.

[0043] For details, see Figure 1The lattice column positioning assembly mainly includes a mounting base 21, a fixing rod 22, a support block 23, and a positioning seat 24. The mounting base 21 is installed on the top of the steel casing 1 to fix and support the upper end of the fixing rod 22 and transfer the load to the steel casing 1. The fixing rod 22 is vertically positioned on the right side of the mounting base 21, with its upper end fixedly connected to the mounting base 21 and its lower end extending downwards below the mounting base 21. The support block 23 is located on the left side of the fixing rod 22 and below the mounting base 21. The support block 23 is connected to the fixing rod 22 and supports the inner wall of the steel casing 1. Through the cooperation of the mounting base 21 and the support block 23, the fixing rod 22 can be stably fixed inside the steel casing 1 during construction. The positioning seat 24 is located on the right side of the fixing rod 22. The left side of the positioning seat 24 is fixedly connected to the lower end of the fixing rod 22. The right side of the positioning seat 24 is provided with a lattice column positioning groove 241. The lattice column is positioned by fitting the lattice column positioning groove 241 with the corner of the lattice column.

[0044] See Figure 4 This application embodiment also provides a lattice column positioning device, including a steel casing 1 and four positioning components 2 evenly distributed along the circumference of the steel casing 1. The positioning components 2 are the lattice column positioning components provided in this application embodiment. The mounting base 21 is installed on the top of the steel casing 1, the fixing rod 22 is located inside the steel casing 1, the support block 23 is supported on the inner wall of the steel casing 1, and the four lattice column positioning grooves 241 form a lattice column positioning cavity 3.

[0045] For details, see Figure 4 The steel casing 1 is a cylindrical structure used to protect the borehole opening during the drilling process of cast-in-place piles. It is typically welded from steel plates and pipes and is an indispensable part of bored pile construction. The function of the steel casing 1 is to prevent soil collapse around the borehole opening and to prevent debris from entering the hole, while also improving the safety and quality of pile foundation construction. During construction, the steel casing 1 is usually driven into the ground, close to the soil, to prevent debris and soil from entering the pile hole. The length and diameter of the steel casing 1 are designed and manufactured according to the specific requirements of the pile foundation construction, and its wall thickness and material are selected according to geological conditions and usage requirements to ensure sufficient strength and durability. Four positioning components 2 are evenly distributed around the top of the steel casing 1, forming a lattice column positioning cavity 3 between the four lattice column positioning slots 241. The lattice column 4 can be lowered into the lattice column positioning cavity 3 and circumferentially positioned to prevent its orientation from changing during the lowering process.

[0046] See Figure 5 During construction, four positioning components 2 are first evenly distributed around the top of the steel casing 1. Inside the steel casing 1, a lattice column positioning cavity 3 is formed between the four lattice column positioning slots 241. Then, the lattice column 4 is lowered into place from the lattice column positioning cavity 3 using hoisting equipment.

[0047] The lattice column positioning component and device provided in this application embodiment, by installing the positioning component 2 on the top of the steel casing 1, can use the lattice column positioning groove 241 on the positioning seat 24 to perform circumferential positioning of the lattice column 4, avoid the change of orientation of the lattice column 4 during the lowering process, so that the orientation of the lattice column 4 after construction meets the design requirements, and avoid the errors and uncertainties caused by manually rotating and adjusting the orientation of the lattice column in traditional construction.

[0048] The lattice column positioning component of this application has a relatively simple structure and small size. It can be directly installed on the top of the steel casing 1 and uses the steel casing 1 as a supporting foundation. There is no need to set up a special platform, which reduces the complexity and difficulty of construction. It has low requirements for the bearing capacity and space of the construction site. It can function normally in areas with limited site space or in complex environments such as valleys and rivers. This good environmental adaptability makes it widely applicable in various underground engineering construction scenarios, effectively solving the problem of limited function of existing positioning components in special environments.

[0049] The mounting base 21 can be installed on the top of the steel casing 1 by hooking, or by using pins, bolts, or other methods.

[0050] To facilitate the installation of the mounting base 21, in some embodiments, see [reference needed]. Figure 1 The mounting base 21 includes an overlapping rod 211 for supporting the top of the steel casing 1 and a limiting block 212 provided at the bottom of the overlapping rod 211. One end of the overlapping rod 211 is connected to the upper end of the fixing rod 22, and a receiving groove 213 for accommodating the top of the steel casing 1 is formed between the overlapping rod 211, the limiting block 212 and the fixing rod 22.

[0051] See Figure 1 The overlapping rod 211 can be set horizontally. The right end of the overlapping rod 211 can be welded to the upper end of the fixing rod 22, or it can be integrally formed. The limiting block 212 can be fixed to the bottom of the overlapping rod 211. The shape and size of the receiving groove 213 formed between the overlapping rod 211, the limiting block 212 and the fixing rod 22 can be set according to the shape and size of the top of the steel casing, so that the mounting seat 21 will not shift or loosen after being installed on the top of the steel casing 1.

[0052] During installation, first place the mounting base 21 above the steel casing 1, and make the receiving groove 213 face the top of the steel casing 1. Control the mounting base 21 to move downward so that the overlapping rod 211 is supported on the top of the steel casing 1, the limiting block 212 contacts the outer wall of the steel casing 1, the upper end of the fixing rod 22 contacts the inner wall of the steel casing 1, and the lower end of the fixing rod 22 contacts the inner wall of the steel casing 1 through the support block 23. At this time, the top of the steel casing 1 is exactly located in the receiving groove 213.

[0053] In some cases, due to manufacturing errors and wear during use, the size of the receiving groove 213 may be slightly larger than the design size, causing the mounting base 21 to wobble radially along the steel casing 1 after being installed on top of the steel casing 1. In this case, the wobble of the mounting base 21 can be prevented by inserting a shim, pad, or wedge between the limiting block 212 and the outer wall of the steel casing 1. In some embodiments, a bolt for abutting against the outer wall of the steel casing 1 can also be threaded onto the limiting block 212. By tightening the bolt, the end of the bolt abuts against the outer wall of the steel casing 1, thereby further improving the firmness of the mounting base 21 on top of the steel casing 1.

[0054] In some embodiments, see Figure 1 , Figure 2 The limiting block 212 is connected to the overlapping rod 211 through the first adjusting mechanism 214. The first adjusting mechanism 214 is used to adjust the distance between the limiting block 212 and the fixed rod 22.

[0055] Correspondingly, the distance between the limiting block 212 and the fixing rod 22 can be adjusted by the first adjustment mechanism 214, thereby enabling the receiving groove 213 to adapt to steel casings 1 with different wall thicknesses and diameters, thus improving the applicability of the entire positioning assembly. Simultaneously, after the mounting base 21 is installed on top of the steel casing 1, the first adjustment mechanism 214 can drive the limiting block 212 closer to the fixing rod 22, causing the limiting block 212 to press against the outer wall of the steel casing 1. This securely clamps the steel casing 1 between the limiting block 212 and the fixing rod 22, preventing the mounting base 21 from wobbling after installation due to manufacturing errors or wear during use.

[0056] The first adjustment mechanism 214 can be a linear drive mechanism, which drives the limit block 212 to reciprocate along a straight line to adjust the distance between the limit block 212 and the fixed rod 22. The linear drive mechanism is a mechanical device that can convert rotary motion or other forms of motion into linear motion, and it can include trapezoidal lead screws, ball screws, electric actuators, linear motors, cylinders, hydraulic cylinders, etc.

[0057] For example, the first adjustment mechanism 214 includes a hand-cranked push rod. A hand-cranked push rod is a mechanical device that achieves linear motion through manual operation. It mainly includes a housing, a handwheel, a transmission mechanism, a push rod, and the housing itself. The housing is fixedly connected to the bottom of the connecting rod 211. The transmission mechanism is located inside the housing. The push rod passes through the housing and can reciprocate along its own axial direction. The handwheel is located outside the housing and is connected to the push rod via the transmission mechanism, converting the rotational motion of the handwheel into the linear motion of the push rod. One end of the push rod is fixedly connected to the limiting block 212. The transmission mechanism may include a worm gear transmission mechanism or a gear transmission mechanism. During operation, the handwheel is manually rotated, and the transmission mechanism converts the rotational motion into the linear motion of the push rod to adjust the distance between the limiting block 212 and the fixed rod 22. Accordingly, the hand-cranked push rod is not only simple in structure and easy to operate, but also occupies little installation space, making the overall positioning assembly relatively compact and easy for workers to move on-site.

[0058] In some embodiments, see Figure 1 , Figure 3 The support block 23 is connected to the fixed rod 22 through the second adjustment mechanism 25, which is used to adjust the distance between the support block 23 and the fixed rod 22.

[0059] Correspondingly, the distance between the support block 23 and the fixed rod 22 can be adjusted through the second adjustment mechanism 25, thereby adjusting the radial position of the positioning seat 24 within the steel casing 1. This allows for the formation of lattice column positioning cavities 3 of different sizes among the four lattice column positioning slots 241, suitable for the construction of lattice columns of different sizes. Furthermore, after the lattice column is lowered into place, the position of the positioning seat 24 can be adjusted through the cooperation of the four second adjustment mechanisms 25, thereby adjusting the verticality of the lattice column. Compared to directly connecting the support block 23 to the fixed rod 22, this method improves the applicability of the entire positioning assembly.

[0060] For example, the second adjustment mechanism 25 is located at the bottom of the positioning seat 24. Accordingly, by placing the second adjustment mechanism 25 at the bottom of the positioning seat 24, the installation space of the fixing rod 22 facing the mounting seat 21 can be saved, the adjustment range of the radial position of the positioning seat 24 within the steel casing 1 can be increased, and the applicability of the entire positioning assembly can be further improved.

[0061] The second adjustment mechanism 25 can be a linear drive mechanism, which drives the support block 23 to reciprocate along a straight line to adjust the distance between the support block 23 and the fixed rod 22. The linear drive mechanism is a mechanical device that can convert rotary motion or other forms of motion into linear motion, and it can include trapezoidal screws, ball screws, electric actuators, linear motors, cylinders, hydraulic cylinders, etc.

[0062] For example, the second adjustment mechanism 25 includes an electric actuator. An electric actuator is an electrically driven device that converts the rotary motion of an electric motor into the linear reciprocating motion of a actuator. The housing of the electric actuator is fixedly connected to the bottom of the positioning seat 24, and the actuator rod is fixedly connected to the support block 23. Accordingly, the electric actuator not only provides greater power but also enables remote control, facilitating worker operation.

[0063] In some embodiments, see Figure 1 The positioning base 24 includes a connecting rod 242 and two positioning rods 243. One end of the connecting rod 242 is connected to the lower end of the fixing rod 22, and the other end of the connecting rod 242 is connected to one end of each of the two positioning rods 243. The other ends of the two positioning rods 243 are spaced apart from each other, forming a lattice column positioning groove 241 between them. For example, the connecting rod 242 and the two positioning rods 243 are all horizontally arranged, with an included angle of 90° between the two positioning rods 243. The second adjustment mechanism 25 is located at the bottom of the connecting rod 242. The fixing rod 22, the connecting rod 242, and the two positioning rods 243 can be an integrally formed structure.

[0064] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
