Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a lifting device of an alternately supported steel platform and an inner climbing tower crane and a construction method thereof. Background Art

[0002] As a new type of construction equipment, the steel platform with alternate support of steel column tube frame has been widely used in the construction of core tubes of high-rise and super high-rise buildings. The steel platform with alternate support of steel column tube frame is often used in conjunction with an internal climbing tower crane. However, the climbing of the steel platform and the internal climbing of the tower crane may result in the following working conditions: before the steel platform climbs, there is not enough space to install the climbing frame of the tower crane, resulting in the inability to install the climbing frame before the steel platform climbs; if the steel platform climbs, the lifting of the climbing steel column will affect the rotation of the tower crane, so the climbing steel column cannot be lifted back, making it impossible to tie the steel bars in the area where the steel bars have not been lifted back. The only way is to wait for the installation of the tower crane climbing frame to be completed. After the tower crane climbs, the climbing steel column can be lifted back and the steel bars can be tied. Due to the above limitations, the lifting of the alternately supported steel platform and the internal climbing tower crane takes a long time, which greatly affects the construction period and cost of the entire construction project. Summary of the invention

[0003] The present invention provides a lifting device of an alternately supported steel platform and an inner climbing tower crane and a construction method thereof to solve the above technical problems.

[0004] In order to solve the above technical problems, the present invention provides a lifting device for an alternatingly supported steel platform and an inner-climbing tower crane, wherein the alternatingly supported steel platform includes a climbing steel column longitudinally installed on a shear wall and a platform body capable of sliding along the climbing steel column; the inner-climbing tower crane includes a tower crane body and a plurality of climbing frames installed on the shear wall and arranged up and down, wherein the climbing frames can provide support for the tower crane body; a top wall device is installed under the platform body, wherein the top wall device includes two states: tightening and loosening, and when the top wall device is tightened, it can provide support for the tower crane body.

[0005] Preferably, there are at least four top wall devices, which are respectively installed on four sides of the platform body.

[0006] Preferably, the top wall device includes an I-beam, a base and support rods extending from the base to both sides, the I-beam is fixedly mounted on the bottom beam of the platform body, and the base is slidably mounted on the I-beam; one end of the support rod is docked with the shear wall, and the other end is docked with the tower crane body.

[0007] Preferably, a crank handle for adjusting the extension length of the support rod is also installed on the base.

[0008] Preferably, pads are provided at both ends of the support rod.

[0009] The present invention also provides a construction method for a lifting device of an alternating support type steel platform and an internal climbing tower crane as described above, including the following steps:

[0010] Step 1: Use the lower climbing frame and the middle climbing frame to climb the tower crane body;

[0011] Step 2: After the tower crane body climbs in place, tighten the top wall device. Before the platform body climbs, the top wall device provides support for the hoisting operation of the internal climbing tower crane;

[0012] Step 3: When the platform body is about to climb, the internal climbing tower crane stops the hoisting operation, loosen the top wall device. After the platform body climbs to completion, tighten the top wall device, and the top wall device provides support for the hoisting operation of the internal climbing tower crane; leave space to install the upper climbing frame; lift the climbing steel column back;

[0013] Step 4: After the upper climbing frame is installed, loosen the top wall device, and the upper climbing frame provides support for the hoisting operation of the internal climbing tower crane.

[0014] Compared with the prior art, the lifting device of the alternating support type steel platform and the internal climbing tower crane provided by the present invention and its construction method have the following advantages: By adding a top wall device under the platform body in this application, the problem that the upper climbing frame can only be installed after the platform body climbs, and after the platform body climbs, the climbing steel column cannot be lifted back, thus affecting the construction period is solved; The top wall device enables the internal climbing tower crane to climb first and still be able to perform normal hoisting operations without the upper climbing frame. At the same time, after the platform body climbs, space can be vacated to install the upper climbing frame, making the climbing process more efficient and reducing the impact on the construction period.

Detailed implementation manners

[0020] In order to more elaborately describe the technical solutions of the above invention, specific embodiments are listed below to prove the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention and are not limited to restricting the scope of the present invention.

[0021] The lifting device of the alternating support type steel platform and the internal climbing tower crane provided by the present invention, as Figure 1 and Figure 2 shown, the alternating support type steel platform 10 includes climbing steel columns 11 longitudinally installed on the shear wall 01 and a platform body 12 capable of sliding along the climbing steel columns 11; the internal climbing tower crane 20 includes a tower crane body 21 and a plurality of climbing frames (including a lower climbing frame 22a, a middle climbing frame 22b, and an upper climbing frame 22c) arranged vertically on the shear wall 01, and the climbing frames can provide support for the tower crane body 21 to ensure the normal progress of hoisting operations; a wall jacking device 13 is installed below the platform body 12, and the wall jacking device 13 has two states of tightening and loosening, and when the wall jacking device 13 is tightened, it can provide support for the tower crane body 21. By adding the wall jacking device 13 below the platform body 12 in this application, the problem that the upper climbing frame 22c can only be installed after the platform body 12 climbs, and after the platform body 12 climbs, the climbing steel columns 11 cannot be lifted back, thus affecting the construction period is solved. That is to say, the wall jacking device 13 can enable the internal climbing tower crane 20 to climb first, and still be able to carry out normal hoisting operations without the upper climbing frame 22c. At the same time, enough space can be vacated after the platform body 12 climbs to install the upper climbing frame 22c, making the climbing process more efficient and reducing the impact on the construction period.

[0022] Please continue to refer to Figure 1 and Figure 2 , in some embodiments, there are at least four wall jacking devices 13, which are respectively installed on four side surfaces of the platform body 12 to disperse the force of the internal climbing tower crane 20 to the surrounding shear walls 01 to ensure construction safety.

[0023] Please refer specifically to Figure 3, in some embodiments, the top wall device 13 includes an I-beam 31, a base 32, and support rods 33 extending from the base 32 to both sides. The I-beam 31 is fixedly installed (e.g., welded) on the bottom beam of the platform body 12. The base 32 is slidably installed on the I-beam 31 for adjusting the position of the base 32 on the platform body 12 as required. One end of the support rod 33 is docked with the shear wall 01, and the other end is docked with the tower crane body 21. The support rod 33 is used to tightly press the shear walls 01 and the tower crane body 21 on both sides, and the shear wall 01 is used to provide sufficient lateral support for the tower crane body 21.

[0024] Please continue to refer to Figure 3 , in some embodiments, a crank handle 34 for adjusting the extended length of the support rod 33 is further installed on the base 32. By turning the crank handle 34, the support rod 33 can be screwed in and out synchronously. At the same time, by using the sliding of the base 32 on the I-beam 31, both support rods 33 are tightly pressed; cushion plates 35 are respectively provided at both ends of the support rod 33 to increase the force-bearing area and avoid damaging the tower crane body 21 and the shear wall 01.

[0025] Please pay key attention to Figure 4 , and in combination with Figures 1 to 3 , the present invention also provides a construction method for a lifting device of an alternating support type steel platform and an internal climbing tower crane as described above, including the following steps:

[0026] Step 1: Use the lower climbing frame 22a and the middle climbing frame 22b to climb the tower crane body 21. At this time, the upper climbing frame 22c has not been installed yet. It should be noted that the lower climbing frame 22a, the middle climbing frame 22b, and the upper climbing frame 22c described in the text are used to distinguish the positions of each climbing frame during the construction process, rather than referring to a specific climbing frame. For example, after the tower crane body 21 climbs to the upper layer, a new upper climbing frame 22c needs to be installed, and the previous upper climbing frame 22c will also be adaptively changed to the middle climbing frame 22b, and so on.

[0027] Step 2: After the tower crane body 21 climbs in place, tighten the top wall device 13. Before the platform body 12 climbs, the top wall device 13 provides support for the hoisting operation of the internal climbing tower crane 20 without affecting the construction progress;

[0028] Step 3: When the platform body 12 is about to climb, the internal climbing tower crane 20 stops hoisting operations, and the top wall device 13 is loosened. After the platform body 12 finishes climbing, the top wall device 13 is tightened, and the top wall device 13 continues to provide support for the hoisting operations of the internal climbing tower crane 20. There is no need to wait for the installation of the upper climbing frame 22c; space is left for installing the upper climbing frame 22c; the climbing steel column 11 is lifted back; that is to say, hoisting operations, the installation of the upper climbing frame 22c, and the lifting back of the climbing steel column 11 can all be carried out synchronously without interference with each other.

[0029] Step 4: After the upper climbing frame 22c is installed, the top wall device 13 is loosened, and the upper climbing frame 22c provides support for the hoisting operations of the internal climbing tower crane 20.

[0030] When the tower crane body 21 needs to climb, repeat the above steps 1-4, thus greatly shortening the waiting time and improving the construction efficiency.

[0031] In summary, the present invention provides a lifting device for an alternating support type steel platform and an internal climbing tower crane and a construction method thereof. The alternating support type steel platform 10 includes a climbing steel column 11 longitudinally installed on a shear wall 01 and a platform body 12 capable of sliding along the climbing steel column 11; the internal climbing tower crane 20 includes a tower crane body 21 and a plurality of climbing frames arranged vertically on the shear wall 01, and the climbing frames can provide support for the tower crane body 21 to ensure the normal progress of hoisting operations; a top wall device 13 is installed below the platform body 12, and the top wall device 13 has two states of being tightened and loosened, and when the top wall device 13 is tightened, it can provide support for the tower crane body 21. By adding the top wall device 13 below the platform body 12 in this application, the problem that the upper climbing frame 22c can only be installed after the platform body 12 climbs, and after the platform body 12 climbs, the climbing steel column 11 cannot be lifted back, thus affecting the construction period is solved. That is to say, the top wall device 13 can enable the internal climbing tower crane 20 to climb first and still be able to carry out normal hoisting operations without the upper climbing frame 22c. At the same time, after the platform body 12 climbs, space can be vacated to install the upper climbing frame 22c, making the climbing process more efficient and reducing the impact on the construction period.

[0032] Obviously, those skilled in the art can make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
