Description

Technical Field

[0001] The invention belongs to the technical field of tower crane foundations, and in particular relates to a seismic isolation tower crane foundation used for seismic isolation building construction. Background Art

[0002] Tower cranes, also known as "tower cranes", are common lifting equipment on construction sites, used for vertical and horizontal transportation of materials and installation of building components. A seismic isolation building refers to a building with a seismic isolation layer formed by seismic isolation bearings at the bottom of the building or between floors. Since the horizontal stiffness of the seismic isolation bearings is very small, it can effectively block the transmission of seismic energy to the building structure above the seismic isolation layer, significantly reducing the seismic response of the building structure above the seismic isolation layer. When the height of the tower crane is high, the tower body is usually fixed to the building structure through a wall attachment device to provide lateral support; the bottom of the tower body is fixed to the ground through the tower crane foundation; however, when the tower crane is used in the construction of a seismic isolation building, due to the existence of a seismic isolation layer in the building structure attached to the tower crane, the building structures above and below the seismic isolation layer will undergo relative horizontal displacement under earthquakes, wind loads or concrete shrinkage, which will eventually cause the tower body to deform and twist or even break and collapse, causing serious safety accidents. In the prior art, the relative horizontal displacement of the building structure above and below the isolation layer is usually limited by using steel pipe scaffolding to connect the upper and lower structures of the isolation support with columns or adopting lateral top support during the construction stage. Although the above method can prevent the horizontal displacement of the building structure to a certain extent, the mechanical properties and load limits that cause the displacement cannot be accurately predicted, so the design of the displacement control measures lacks a scientific calculation basis, resulting in insufficient connection reliability, easy loosening and falling off, poor overall stability, easy deformation, etc., resulting in uncontrollable safety risks in the use of tower cranes. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a seismic isolation tower crane foundation for seismic isolation building construction, which enables the tower body to move and reset synchronously with the seismic isolation building, effectively improving the safety of tower crane use.

[0004] The technical solution adopted by the present invention is: an isolation tower crane foundation for isolation building construction, including a concrete foundation with a stepped groove, the stepped groove including a lower narrow groove and an upper wide groove; a seismic isolation bearing is provided in the lower narrow groove; an anti-overturning reaction beam is provided in the upper wide groove; a tower crane pedestal is provided between the seismic isolation bearing and the anti-overturning reaction beam, a steel ball universal ball is provided on the top of the tower crane pedestal, and is connected to the bottom column of the tower crane, and the steel ball universal ball is rollingly connected to the anti-overturning reaction beam.

[0005] Furthermore, the lower narrow groove is provided with a space adapted to the designed maximum displacement of the seismic isolation bearing.

[0006] Furthermore, in the initial state, the distance between at least one of the steel ball universal balls and the projected edge of the anti-overturning reaction beam on the tower crane pedestal is greater than the designed maximum displacement.

[0007] Furthermore, the tower crane pedestal includes an upper connecting plate, a lower connecting plate and reinforcing ribs arranged between the upper connecting plate and the lower connecting plate; the steel ball universal ball and the bottom column of the tower crane are fixed to the upper connecting plate; the lower connecting plate is fixed to the seismic isolation bearing by connecting bolts.

[0008] Furthermore, the upper connecting plate is square, the steel ball universal balls are evenly and symmetrically arranged in the middle of the edge of the upper connecting plate, and the bottom columns of the tower crane are fixed to the corners of the upper connecting plate.

[0009] Furthermore, the anti-overturning reaction beam is a cross structure, the center of the anti-overturning reaction beam is aligned with the center of the upper connecting plate, and the four supporting beams of the anti-overturning reaction beam extend to the outside of the upper connecting plate in a direction perpendicular to the edge of the upper connecting plate and are fixed to the upper wide groove through embedded parts.

[0010] Furthermore, the steel ball universal ball includes a fixing rod, a ball seat and a steel ball; the fixing rod is threadedly connected to the upper connecting plate; the ball seat is arranged on the top of the fixing rod and is provided with a concave cavity matching the steel ball; the steel ball is rollingly embedded in the concave cavity.

[0011] Furthermore, the seismic isolation bearing includes a rubber bearing and an upper flange plate and a lower flange plate arranged at the upper and lower ends of the rubber bearing, the upper flange plate is connected to the lower connecting plate; the lower flange plate is fixed to the lower narrow groove by embedded bolts.

[0012] Furthermore, it also includes a seismic isolation cover plate covering the upper wide groove, and the covering area of ​​the seismic isolation cover plate is larger than the opening area of ​​the upper wide groove.

[0013] Furthermore, the seismic isolation cover plate is provided with a through hole adapted to the bottom column of the tower crane.

[0014] The advantages and positive effects of the present invention are:

[0015] The present application sets the tower crane pedestal on the seismic isolation support so that the tower body can be horizontally displaced synchronously with the building structure. When an earthquake occurs during construction, or a typhoon or strong wind occurs, or the seismic isolation building structure moves horizontally due to concrete drying shrinkage and temperature deformation, the twisting deformation and even fracture damage caused by the fixed connection of the tower crane foundation is avoided, and the safety performance of the tower crane under different working conditions is significantly enhanced.

[0016] By setting up the anti-overturning reaction beam and steel ball universal ball, sufficient anti-overturning bending moment can be provided to the tower crane pedestal without restricting the horizontal displacement of the tower crane pedestal, thereby avoiding tensile damage to the seismic isolation bearing and further ensuring the safety of the tower crane.

[0017] By scientifically and rationally designing the positional relationship between the steel ball universal ball and the anti-overturning reaction beam and the shape of the anti-overturning reaction beam, it is ensured that even when the tower crane pedestal undergoes horizontal displacement, the anti-overturning reaction beam can still effectively form an anti-overturning bending moment on the tower crane pedestal, thereby improving the stability and safety of the overall structure.

[0029] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0030] Figure 1 The connection structure of a tower crane and a seismic isolation building in a specific embodiment of the present application is shown, wherein a plurality of seismic isolation bearings 1 are provided at the bottom of the seismic isolation building 9, the tower body 8 of the tower crane is formed by splicing standard tower crane sections 81, and the tower body 8 is connected to the seismic isolation building 9 through a wall attachment device 82; in the prior art, the bottom of the tower body 8 is directly fixed on a concrete foundation 7 arranged on one side of the seismic isolation building 9, and when the seismic isolation building 9 undergoes horizontal displacement under the action of an earthquake, wind load or concrete shrinkage, a horizontal load is applied to the tower body 8 through the wall attachment device 82. At this time, the upper and bottom parts of the tower body 8 are simultaneously subjected to opposite forces, and it is difficult to avoid deformation, distortion or even fracture and collapse, causing major safety accidents; the seismic isolation tower crane foundation for seismic isolation building construction proposed in the present application can make the tower body 8 move synchronously with the seismic isolation building 9 when the seismic isolation building 9 undergoes horizontal displacement, thereby avoiding deformation and distortion of the tower body 8 and ensuring the safe use of the tower crane.

[0031] like Figure 2 , Figure 3 As shown, the present invention proposes a seismic isolation tower crane foundation for seismic isolation building construction, including a concrete foundation 7 with a stepped groove, the stepped groove including a lower narrow groove and an upper wide groove; a seismic isolation bearing 1 is provided in the lower narrow groove; an anti-overturning reaction beam 4 is provided in the upper wide groove; a tower crane pedestal 2 is provided between the seismic isolation bearing 1 and the anti-overturning reaction beam 4, a steel ball universal ball 3 is provided on the top of the tower crane pedestal 2, and is connected to the bottom column 6 of the tower crane, and the steel ball universal ball 3 is rollingly connected to the anti-overturning reaction beam 4.

[0032] The seismic isolation support 1 in the present application has good vertical bearing capacity, horizontal elastic restoring force and damping performance. By installing the tower crane base 2 on the seismic isolation support 1 and then fixing the tower crane bottom column 6 on the tower crane base 2, not only can the seismic isolation support 1 effectively bear the vertical load during the installation and use of the tower crane, but also the tower body 8 can be horizontally displaced when the tower body 8 is subjected to the horizontal tension of the building structure to which it is attached, so that the tower body 8 can be horizontally displaced synchronously with the building structure, and reset synchronously with the building structure after the tension is eliminated, meeting the tower crane use requirements. In order to meet the different working conditions during the construction of the seismic isolation building 9, the stability and safety of the tower crane are improved. At the same time, since the seismic isolation bearing 1 is not allowed to be subjected to tension during use, the present application arranges the anti-overturning reaction beam 4 on the upper part of the tower crane pedestal 2 and connects it to the tower crane pedestal 2 in a rolling manner through the steel ball universal ball 3, so that the anti-overturning reaction beam 4 can provide sufficient anti-overturning bending moment to the tower crane pedestal 2 without restricting the horizontal displacement of the tower crane pedestal 2, thereby avoiding tensile damage to the seismic isolation bearing 1 and further ensuring the safety of the tower crane.

[0033] The tower crane bottom column 6 in the present application is the column of the tower crane standard section 81 at the bottom of the tower body 8; the lower narrow groove is provided with a space adapted to the designed maximum displacement of the seismic isolation bearing 1. Since the seismic isolation bearing 1 and the tower crane pedestal 2 are both located inside the lower narrow groove, the internal space size of the narrow groove is set according to the designed maximum displacement of the seismic isolation bearing 1, so that it can meet the needs of horizontal displacement of the seismic isolation bearing 1 and the tower crane pedestal 2. Specifically, the cross-sectional shape of the lower narrow groove can be set to a circular, square or other shape as needed. Preferably, the cross-sectional shape of the lower narrow groove is designed to be circular, and the distance between the seismic isolation bearing 1 and the tower crane pedestal 2 and the inner wall of the lower narrow groove is greater than the designed maximum displacement of the seismic isolation bearing 1. This design can better adapt to the needs of horizontal displacement of the seismic isolation bearing 1 and the tower crane pedestal 2 in different directions.

[0034] Furthermore, in order to ensure that when the tower crane pedestal 2 undergoes horizontal displacement, the anti-overturning reaction beam 4 can still effectively form an anti-overturning bending moment on the tower crane pedestal 2, in the initial state, the distance between at least one steel ball universal ball 3 and the projected edge of the anti-overturning reaction beam 4 on the tower crane pedestal 2 is greater than the designed maximum displacement, ensuring that at least one steel ball universal ball 3 is always in rolling connection with the anti-overturning reaction beam 4, that is, even if the tower crane pedestal 2 undergoes maximum displacement, at least one steel column 33 universal ball on the moved tower crane pedestal 2 is still in rolling connection with the anti-overturning reaction beam 4, thereby continuing to exert the function of the anti-overturning reaction beam 4 and effectively preventing the tower crane from tipping over. At the same time, when the horizontal tension on the upper tower body 8 of the tower crane pedestal 2 is eliminated, the steel ball universal ball 3 can help the tower crane pedestal 2 to achieve reset, thereby improving the stability and safety of the overall structure.

[0035] In a specific embodiment, Figure 4As shown, the tower crane base 2 includes an upper connecting plate 22, a lower connecting plate 21 and a reinforcing rib 23 arranged between the upper connecting plate 22 and the lower connecting plate 21; the steel ball universal ball 3 and the bottom column 6 of the tower crane are fixed to the upper connecting plate 22; the lower connecting plate 21 is fixed to the seismic isolation bearing 1 by connecting bolts; specifically, since the installation surface of the seismic isolation bearing 1 is relatively small, the area of ​​the above-mentioned connecting plate matches the installation surface of the seismic isolation bearing 1, and the area of ​​the upper connecting plate 22 matches the installation area required for the bottom column 6 of the tower crane. By setting the tower crane base 2, sufficient installation space is provided for the steel ball universal ball 3 and the bottom column 6 of the tower crane, so that the tower crane and the seismic isolation bearing 1 are effectively and stably connected.

[0036] Preferably, the upper connecting plate 22 is square, the steel ball universal ball 3 is evenly and symmetrically arranged in the middle of the edge of the upper connecting plate 22, and the bottom column 6 of the tower crane is fixed to the corner of the upper connecting plate 22. This arrangement can make fuller and more effective use of the area of ​​the upper connecting plate 22, and at the same time make the connection between the upper connecting plate 22 and the anti-overturning reaction beam 4 more stable; specifically, the bottom column 6 of the tower crane is arranged at the four corners of the upper connecting plate 22, which can not only evenly transfer the pressure load transmitted by the tower crane to the upper connecting plate 22, but also minimize the area of ​​the upper connecting plate 22; at the same time, a number of steel ball universal balls 3 are respectively arranged in the middle of the four edges of the upper connecting plate 22, which can not only be staggered with the bottom column 6 of the tower crane, but also more easily cooperate with the anti-overturning reaction beam 4, and also make the pressure load of the anti-overturning reaction beam 4 evenly transferred to the upper connecting plate 22, so that the force on each part of the upper connecting plate 22 is more balanced and the overall structure is more stable; further, a reinforcement is also provided at the connection between the bottom column 6 of the tower crane and the upper connecting plate 22.

[0037] Preferably, if Figure 5 As shown, the anti-overturning reaction beam 4 is a cross structure, the center of the anti-overturning reaction beam 4 is aligned with the center of the upper connecting plate 22, and the four supporting beams 41 of the anti-overturning reaction beam 4 extend to the outer side of the upper connecting plate 22 in a direction perpendicular to the edge of the upper connecting plate 22, and are fixed to the upper wide groove through the embedded parts 42. By setting the anti-overturning reaction beam 4 as a cross structure, it is ensured that the anti-overturning reaction beam 4 has enough area to maintain the rolling connection with the steel ball universal ball 3, and at the same time avoids the tower crane bottom column 6, so that the tower crane bottom column 6 has enough horizontal movement space, and can be well matched with the tower crane base 2, which not only ensures the realization of the maximum design displacement of the rubber bearing 11, but also can give full play to the anti-overturning effect of the anti-overturning reaction beam 4.

[0038] like Figure 6As shown, the above-mentioned steel ball universal ball 3 includes a fixing rod 31, a ball seat 32 and a steel ball; the upper connecting plate 22 is provided with a threaded hole 25, and the fixing rod 31 is provided with a thread matching the threaded hole 25, and is threadedly connected to the upper connecting plate 22; the ball seat 32 is arranged on the top of the fixing rod 31, and is provided with a concave cavity matching the steel ball; the steel ball is rolled and embedded in the concave cavity; through the threaded connection between the fixing rod 31 and the upper connecting plate 22, the height of the steel ball universal ball 3 on the upper connecting plate 22 can be conveniently adjusted, so as to achieve effective connection with the anti-overturning reaction beam 4, and ensure that the anti-overturning reaction beam 4 can apply an anti-overturning moment through the steel column 33 universal wheel tower crane pedestal 2; preferably, the concave cavity can cover more than half of the surface of the steel ball, so that the steel ball can roll freely in the concave cavity without falling out of the concave cavity; the outer surface shape of the ball seat 32 is set to a shape similar to a hexagonal nut, so that the staff can install and adjust the height of the steel ball universal ball 3.

[0039] The above-mentioned seismic isolation bearing 1 can be a rubber seismic isolation bearing 1, a steel plate spherical seismic isolation bearing 1, a shape memory seismic isolation bearing 1 or any other seismic isolation bearing 1 that can achieve seismic isolation effect, horizontal displacement and reset effect. Preferably, Figure 7 As shown, the seismic isolation bearing 1 adopts the same seismic isolation bearing 1 as the seismic isolation building 9 to which the tower crane is attached, so that the seismic isolation bearing 1 of the tower crane foundation and the seismic isolation bearing 1 of the seismic isolation building 9 have the same characteristics and designed maximum displacement, ensuring that the tower crane can move and reset synchronously with the seismic isolation building 9. In a specific embodiment, the seismic isolation bearing 1 includes a rubber bearing 11 and an upper flange plate 13 and a lower flange plate 12 arranged at the upper and lower ends of the rubber bearing 11. The upper flange plate 13 is connected to the lower connecting plate 21 through the connecting hole 24 on the lower connecting plate 21 by the fixing bolt 15; the lower flange plate 12 is fixed to the lower narrow groove by the embedded bolt 14. When in use, the lower flange is always fixed at the bottom of the lower narrow groove, and the rubber bearing 11 is deformed when the tower body 8 is subjected to tension, so that the upper flange plate 13 is displaced relative to the lower flange plate 12, thereby realizing the synchronous movement and reset of the tower body 8 and the seismic isolation building 9, thereby enhancing the safety of the tower crane.

[0040] Furthermore, if Figure 8 As shown, the seismic isolation tower crane foundation for seismic isolation building construction proposed in the present application also includes a seismic isolation cover plate 5 covering the upper wide groove. The coverage area of ​​the seismic isolation cover plate 5 is larger than the opening area of ​​the upper wide groove, which can achieve effective closure of the step-shaped groove to avoid safety accidents caused by people falling in, and garbage, rainwater, etc. falling into the step-shaped groove to affect the normal use of the tower crane foundation; specifically, the seismic isolation cover plate 5 is not fixed on the concrete foundation 7. When the tower body 8 moves horizontally, the seismic isolation cover plate 5 has a sufficient area to keep covering the step-shaped groove while moving synchronously with the tower body 8.

[0041] In a specific embodiment, the seismic isolation cover plate 5 is provided with a through hole adapted to the tower crane bottom column 6, and the tower crane bottom column 6 has a sufficient height so that it can be connected to the tower crane pedestal 2 after passing through the through hole; in a specific embodiment, the seismic isolation cover plate 5 includes a horizontal plate and an inclined plate, the horizontal plate is square, the inclined plate is trapezoidal and is arranged around the horizontal plate, the through holes are arranged at the four corners of the intersection of the horizontal plate and the inclined plate, and the size of the through holes matches the cross-sectional shape of the tower crane bottom column 6; the bottom of the inclined plate is set on the top surface of the concrete foundation 7 around the upper wide groove. This arrangement can ensure that the seismic isolation cover plate 5 has a good sealing effect and can move synchronously with the tower crane bottom column 6.

[0042] The present application sets the tower crane pedestal on the seismic isolation support so that the tower body can be horizontally displaced synchronously with the building structure. When an earthquake occurs during construction, or a typhoon or strong wind occurs, or the seismic isolation building structure moves horizontally due to concrete drying shrinkage and temperature deformation, the twisting deformation and even fracture damage caused by the fixed connection of the tower crane foundation is avoided, and the safety performance of the tower crane under different working conditions is significantly enhanced.

[0043] By setting up the anti-overturning reaction beam and steel ball universal ball, sufficient anti-overturning bending moment can be provided to the tower crane pedestal without restricting the horizontal displacement of the tower crane pedestal, thereby avoiding tensile damage to the seismic isolation bearing and further ensuring the safety of the tower crane.

[0044] By scientifically and rationally designing the positional relationship between the steel ball universal ball and the anti-overturning reaction beam and the shape of the anti-overturning reaction beam, it is ensured that even when the tower crane pedestal undergoes horizontal displacement, the anti-overturning reaction beam can still effectively form an anti-overturning bending moment on the tower crane pedestal, thereby improving the stability and safety of the overall structure.

[0045] The anti-overturning reaction beam, tower crane pedestal and seismic isolation bearing in the present application are all detachably connected, which is convenient for installation and disassembly and is conducive to turnover use; the overall structure is stable, the connection is reliable, the construction is convenient, and it has good practicality.

[0046] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
