Description

Technical Field

[0001] This invention relates to the field of tower crane foundation technology, and in particular to a lattice-type tower crane foundation reinforcement device and method based on telescopic connecting rods. Background Technology

[0002] A tower crane foundation is the basic structure that secures the tower crane's tower body and prevents it from tilting. It typically uses a combination of lattice columns and cast-in-place piles to stabilize the tower. In the construction process, the installation location of the tower crane is first determined. Then, according to the design requirements, cast-in-place piles are constructed at the installation location. The lattice columns are then installed on these piles, and finally, the tower body is installed. This foundation structure can adapt to a wider range of geological conditions and is widely used in current technology.

[0003] However, the existing tower crane foundation structure is simple, especially since there is no connecting structure between the lattice columns. Each lattice column bears the load independently, resulting in poor stability of the tower crane foundation and potential safety hazards.

[0004] Therefore, existing tower crane foundations suffer from low strength and poor stability. Summary of the Invention

[0005] The present invention provides a lattice-type tower crane foundation reinforcement device and method based on telescopic connecting rods, which solves the technical problems of low strength and poor stability of tower crane foundations in the prior art.

[0006] Some implementation schemes for solving the above-mentioned technical problems include: In a first aspect, a lattice-type tower crane foundation reinforcement device based on telescopic connecting rods includes lattice columns, which are installed on cast-in-place piles. There are multiple lattice columns arranged in parallel, and the cross-sectional shape of the area enclosed by the lattice columns is polygonal. The telescopic rod is connected between two adjacent lattice columns, and the space between the two adjacent lattice columns includes a horizontally arranged telescopic rod and a telescopic rod inclined relative to the horizontal plane; The telescopic rod is mounted on the lattice column via the connecting assembly. The connecting component includes a connecting piece disposed on the lattice column, and the connecting component also includes a connecting seat disposed on the telescopic rod. The connecting seat is provided with a connecting groove that mates with the connecting piece, and the connecting piece is disposed in the connecting groove by a connecting pin. The connector is provided with at least two connecting slots, each connecting slot cooperating with an independent connecting piece.

[0007] Preferably, the connecting piece is welded to the lattice column, or the connecting piece and the lattice column are an integral structure.

[0008] Preferably, the lattice column is provided with a base, and the connecting piece is disposed on the lattice column through the base. The connecting piece and the base are an integral structure, or the connecting piece is welded to the base.

[0009] Preferably, the connecting piece is provided with a pin hole that mates with the connecting pin, and the connecting seat is provided with a connecting hole that mates with the connecting pin, the connecting hole communicating with the connecting groove.

[0010] Preferably, each end of the connecting pin is provided with a snap ring pin to prevent the connecting pin from disengaging from the connecting hole.

[0011] Preferably, the telescopic rod includes two rods, and the telescopic rod further includes a driving member disposed between the two rods and used to drive the two rods to move closer or further apart from each other, and the connecting seat is provided at the end of each rod away from the driving member.

[0012] Preferably, the connecting seat is welded to the rod, or the connecting seat and the rod are an integral structure.

[0013] Preferably, the rod is provided with an internal thread, and the internal threads of the two rods have opposite directions of rotation. The driving member includes a screw, and the two ends of the screw are respectively provided with a positive thread portion and a negative thread portion, and the thread direction of the positive thread portion is opposite to that of the thread direction of the negative thread portion.

[0014] Preferably, the driving component further includes an operating part, which is integral with the screw. The cross-sectional shape of the driving part is polygonal, and the driving part is located between the positive thread part and the negative thread part.

[0015] Secondly, a method for reinforcing the foundation of a lattice-type tower crane based on telescopic connecting rods includes the following steps: Measure the distance between two adjacent cast-in-place piles and determine the shape enclosed by all the cast-in-place piles; The relative positions of all lattice columns are determined based on the shape formed by all the cast-in-place piles, and all lattice columns are fixed in their respective positions. A horizontally arranged telescopic rod is installed between two adjacent lattice columns, wherein there are multiple horizontally arranged telescopic rods and they are evenly distributed along the vertical direction of the lattice columns. The verticality of the lattice columns is measured, and the verticality of all the lattice columns is adjusted by adjusting the length of the telescopic rods set along the horizontal direction; After all the lattice columns meet the verticality requirements, telescopic rods inclined relative to the horizontal plane are installed. After each telescopic rod inclined relative to the horizontal plane is installed, the verticality of the lattice column connected to the telescopic rod is measured, and the verticality of the lattice column is adjusted by adjusting the length of the telescopic rod inclined relative to the horizontal plane. After the telescopic rods are installed, the verticality of all lattice columns is measured again. The verticality of the lattice columns is adjusted by adjusting the length of the horizontally set telescopic rods and / or adjusting the length of the telescopic rods that are inclined relative to the horizontal plane, so that the verticality of all the lattice columns meets the design requirements, and the assembly of the lattice foundation is completed. The assembled lattice foundation is then installed onto the cast-in-place piles.

[0016] Compared with the prior art, the present invention has the following advantages: By installing telescopic rods, the overall integrity of the tower crane foundation is effectively improved. The horizontally and diagonally installed telescopic rods form the entire lattice column and other components of the lattice foundation into a whole, effectively balancing the stress between the lattice columns and reducing the swaying and tilting during tower crane operation.

[0017] By installing telescopic booms, the stability of the tower crane foundation is effectively improved. The telescopic boom's flexibility enhances the tightness of connecting components during actual operation. After installation, adjusting the length of the telescopic boom allows for the tightening of connecting components such as lattice columns, thus improving the stability of the tower crane foundation.

[0018] It is easy to construct and reusable. Using telescopic rods as the connecting structure allows for adjustments based on the spacing specifications of the various lattice columns of the tower crane on site, improving the utilization rate of the telescopic rods and reducing construction costs.

[0019] This solution is applicable to reinforcing lattice tower crane foundations, especially for tower crane foundations whose original design load is insufficient and require improvement in overturning resistance, or for tower crane foundations that require frequent lifting of heavy objects or exposure to strong winds / earthquakes and require enhanced fatigue resistance.

[0020] This method, by setting up telescopic rods and fixing them to the lattice columns, can form the lattice columns into a whole, improving the stability and strength of the tower crane foundation. In addition, this method facilitates the construction of the tower crane foundation, making the construction convenient and efficient, and reducing the labor intensity of construction workers.

[0030] The specific embodiments shown below are intended to describe various configurations of the subject matter of the invention and are not intended to represent the only configuration in which the subject matter of the invention can be practiced. The specific embodiments include particular details intended to provide a thorough understanding of the subject matter of the invention. However, it will be clear and apparent to those skilled in the art that the subject matter of the invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0031] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0032] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] Reference Figures 1 to 5 As shown, in the first aspect, a lattice-type tower crane foundation reinforcement device based on telescopic connecting rods includes lattice columns 1, which are installed on cast-in-place piles 11. There are multiple lattice columns 1, which are arranged in parallel, and the cross-sectional shape of the area enclosed by the lattice columns 1 is polygonal. Telescopic rod 2, the telescopic rod 2 is connected between two adjacent lattice columns 1, and the two adjacent lattice columns 1 include the horizontally arranged telescopic rod 2 and the telescopic rod 2 inclined relative to the horizontal plane; The telescopic rod 2 is mounted on the lattice column 1 via the connecting component 3. The connecting component 3 includes a connecting piece 31 disposed on the lattice column 1, and the connecting component 3 also includes a connecting seat 32 disposed on the telescopic rod 2. The connecting seat 32 is provided with a connecting groove that cooperates with the connecting piece 31, and the connecting piece 31 is disposed in the connecting groove by a connecting pin. The connector 32 is provided with at least two connector slots, each connector slot cooperating with an independent connector piece 31.

[0034] It is understandable that the grid column 1 can be made of metal. The telescopic rod 2 and the connecting component 3 can also be made of metal. At the same time, the telescopic rod 2 and the connecting component 3 should be coated with anti-rust paint to prevent oxidation and rust.

[0035] Reference Figures 1 to 5 As shown, in some embodiments, the connecting piece 31 is welded to the lattice column 1, or the connecting piece 31 and the lattice column 1 are an integral structure.

[0036] When the lattice column 1 does not have other functions, or when the lattice column 1 does not bear other forces, the connecting piece 31 can be directly installed on the lattice column 1. For example, the lattice column 1 and the connecting piece 31 are an integral structure.

[0037] There are usually multiple connecting pieces 31, and multiple connecting pieces 31 are connected to the same connecting seat 32. When the same connecting seat 32 is engaged with multiple connecting pieces 31, the connecting pieces 31, the connecting seat 32 and the lattice column 1 are all subjected to uniform force, and stress concentration is not easy to occur.

[0038] Reference Figures 1 to 4 As shown, in practice, the lattice column 1 also bears its own force, or when it is not appropriate to directly install the connecting piece 31 on the lattice column 1, in some embodiments, the lattice column 1 is provided with a base 33, and the connecting piece 31 is installed on the lattice column 1 through the base 33. The connecting piece 31 and the base 33 are an integral structure, or the connecting piece 31 is welded to the base 33.

[0039] The connecting piece 31 and the lattice column 1 adopt a split structure, which makes the connecting piece 31 and the lattice column 1 more versatile and applicable to different application scenarios.

[0040] In some embodiments, the connecting piece 31 is provided with a pin hole that mates with the connecting pin, and the connecting seat 32 is provided with a connecting hole that mates with the connecting pin, the connecting hole communicating with the connecting groove.

[0041] Connecting pins are used to connect connecting piece 31 to connecting groove. Connecting pins are easy to operate. During installation or removal, it is only necessary to pull out or insert the connecting hole and through hole. The tower crane foundation is easy to construct.

[0042] In some embodiments, the two ends of the connecting pin are respectively provided with snap ring pins to prevent the connecting pin from disengaging from the connecting hole.

[0043] In some embodiments, the telescopic rod 2 includes two rods 21. The telescopic rod 2 also includes a driving member disposed between the two rods 21 and used to drive the two rods 21 to move closer or further away from each other. The connecting seat 32 is provided at the end of each of the two rods 21 away from the driving member.

[0044] In some embodiments, the connecting seat 32 is welded to the rod 21, or the connecting seat 32 and the rod 21 are an integral structure.

[0045] Reference Figures 1 to 5 As shown, in some embodiments, the rod 21 is provided with internal threads, and the internal threads of the two rods 21 have opposite directions of rotation. The driving member includes a screw 22, and the two ends of the screw 22 are respectively provided with a positive thread portion and a negative thread portion. The thread direction of the positive thread portion is opposite to that of the thread direction of the negative thread portion.

[0046] External threads can also be provided on rod 21, and internal threads can be provided in the drive component.

[0047] Reference Figure 5 As shown, in some embodiments, the driving member further includes an operating part 23, which is an integral structure with the screw 22. The cross-sectional shape of the driving part is polygonal, and the driving part is located between the positive thread part and the negative thread part.

[0048] The drive unit can be operated with tools such as wrenches.

[0049] Secondly, a method for reinforcing a lattice-type tower crane foundation based on retractable connecting rods includes the following steps: Measure the distance between two adjacent cast-in-place piles 11 and determine the shape enclosed by all the cast-in-place piles 11; The relative positions of all lattice columns 1 are determined according to the shape formed by all the cast-in-place piles 11, and all lattice columns 1 are fixed in the corresponding positions; A horizontally arranged telescopic rod 2 is provided between two adjacent lattice columns 1, wherein there are multiple horizontally arranged telescopic rods 2 and they are evenly arranged along the vertical direction of the lattice columns 1. The verticality of the lattice column 1 is measured, and the verticality of all the lattice columns 1 is adjusted by adjusting the length of the telescopic rod 2 set along the horizontal direction; After all the verticality of the lattice columns 1 meets the requirements, the telescopic rods 2 that are inclined relative to the horizontal plane are installed. After each telescopic rod 2 that is inclined relative to the horizontal plane is installed, the verticality of the lattice column 1 connected to the telescopic rod 2 that is inclined relative to the horizontal plane is measured, and the verticality of the lattice column 1 is adjusted by adjusting the length of the telescopic rod 2 that is inclined relative to the horizontal plane. After the telescopic rod 2 is installed, the verticality of all lattice columns 1 is measured again, and the verticality of the lattice columns 1 is adjusted by adjusting the length of the horizontally set telescopic rod 2 and / or adjusting the length of the telescopic rod 2 set inclined relative to the horizontal plane, so that the verticality of all the lattice columns 1 meets the design requirements, and the assembly of the lattice foundation is completed. The assembled lattice foundation is installed on the cast-in-place pile 11.

[0050] The technical solution of the present invention will be further described below with reference to specific application methods: The principle of this invention is to use telescopic connecting rods 21, i.e. telescopic rods 2, to fix the lattice column 1 of the lattice tower crane in both the horizontal and diagonal directions. By connecting the bottom lattice foundation into a whole, the stability of the tower crane foundation is improved, thereby enhancing the overall stability of the tower crane.

[0051] Telescopic rod 2 is assembled with a Ф70mm Q235B screw 22 and a Q235B steel pipe (outer diameter 159 mm, wall thickness 8.0 mm), with an adjustment range of ±200mm. The main rod 21 has a cross-sectional area of ​​3795mm². 2 Ф70 screw, 22mm cross-sectional area, 3848mm² 2 The cross-sectional area of ​​the connecting piece is 31 mm. 2 All of the above materials are larger than the 3757mm² cross-sectional area of ​​a single leg of a commonly used tower crane lattice column L140*140*14. 2 .

[0052] Three expansion joints are used to reinforce each pair of lattice columns 1. Generally, the lattice columns 1 of the tower crane are arranged in a square with four columns, that is, 12 expansion joints are used to reinforce the lattice columns 1 around one circle.

[0053] The telescopic rod 2, formed by the screw 22 and the rod 21, can extend or retract by turning the intermediate operating part 23. The connecting piece 31 on the lattice column 1 can mate with the connecting groove on the telescopic rod 2. After the assembly is completed, it is fixed with a pin.

[0054] The strength of telescopic rod 2 is based on GB50017 and GB / T228.1, with a design tensile stress of 120KN and a design compressive stress of 200KN.

[0055] During construction, the tower crane installation location is selected based on site requirements, and the installation method is determined according to the geological conditions and the scope of construction. The construction method described in this article is suitable for lattice-type tower crane foundation construction, typically used in areas with complex geological environments or where high stability requirements are placed on the tower crane during construction. Under these conditions, the construction method described in this article is used to reinforce the foundation of lattice column 1.

[0056] Prepare relevant materials, including connecting plates, telescopic rods 2, and pins. The telescopic rods 2 are post-installed, meaning one end of rod 21 has a bolt hole for connecting the threaded rod 22. After installation, the length is adjustable by rotating the threaded rod 22. The other end is welded with a square ear plate. The connecting seat 32 and the square ear plate are an integral structure, facilitating subsequent connection and welding of the connecting piece 31 to the lattice column 1. The load-bearing capacity of the telescopic rod 2 is determined through calculations of the lattice steel column, taking into account the vertical load, horizontal load, and overturning moment borne by the lattice steel column. Based on the load analysis results, the cross-sectional dimensions and material strength of the telescopic rod are checked. The lattice column 1 is anchored 2.5m into the cast-in-place pile 11. The lower part of the lattice column 1's foundation is the bored cast-in-place pile 11, and the upper part is the lattice column 1. During on-site construction, after the reinforcing cage of the bored cast-in-place pile 11 is lowered, the lattice column 1 is installed, and finally, concrete pouring is carried out. Complete the construction of lattice column 1.

[0057] During construction, attention should be paid to accurately positioning the lattice column 1, straightening it, and ensuring its verticality.

[0058] After completing the above operations, install connecting seats 32 on the two expansion joints and weld connecting pieces 31 onto the lattice column 1. Since the lattice column 1 is mostly made of steel, select suitable locations (generally welded at the lower and upper positions to facilitate subsequent installation of the diagonal members 21) to weld the connecting pieces 31. If it is difficult to find suitable locations for the steel on the lattice column 1, or considering the inherent function of the steel on the lattice column 1, making it unsuitable to directly install the connecting pieces 31, a steel plate can be welded around the lattice column 1 to form a base 33, making the stress more even, and then the connecting pieces 31 can be welded onto the base 33. The base 33 is also used to position the connecting pieces 31, facilitating the subsequent connection between the connecting pieces 31 and the connecting seats 32 using pins.

[0059] It is recommended to use a screw 22 with a length greater than 600mm to facilitate subsequent adjustment of the length of the telescopic rod 2. An operating part 23 is provided on the screw 22 and welded in place. One end of the connecting rod is welded with a connecting seat 32 for connecting with the connecting piece 31 of the lattice column 1, and the other end is provided with a screw hole for connecting with the screw 22. The rod 21 remains hollow to facilitate adjustment of the length of the telescopic rod 2 in conjunction with the screw 22.

[0060] Connect the four lattice columns 1 of the tower crane foundation sequentially according to the above operation method, including the horizontally installed telescopic rods 2 and the diagonally installed telescopic rods 2, to form the entire lattice foundation into a whole and improve the stability of the structure. Horizontally refers to the horizontal direction.

[0061] After removal, to facilitate storage and transportation, the screw 22 in the middle of the two telescopic rods should be removed and cleaned.

[0062] The technical solution of the present invention and its corresponding details have been described above. It is understood that the above description is only some implementation schemes of the technical solution of the present invention, and some details may be omitted in the specific implementation.

[0063] Furthermore, in some embodiments of the above invention, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine and implement the above embodiments according to their needs to obtain a better application experience.

[0064] When implementing the subject matter of this invention, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter and drawings. Obviously, these details are still within the scope of the subject matter of this invention without departing from it.
