Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a multi-scenario lifting and splicing tower-building system, and also to a multi-scenario lifting and splicing tower-building method. Background Art

[0002] Tower cranes are large-scale intelligent construction equipment used in the construction of bridge towers and airport towers. Existing tower construction technology is usually a traditional scaffolding plus flip formwork construction technology, which uses steel pipe scaffolding to build peripheral supports, and pours concrete layer by layer with wooden or steel formwork. After each section (about 3-4 meters) is completed, the formwork is removed and re-erected to the upper layer, or a tower crane plus loose formwork construction technology, which uses a tower crane to hoist loose formwork and materials, assembles and pours them section by section, which relies more on high-altitude manual operations and has low formwork turnover efficiency. The above traditional technologies have problems such as low efficiency, high safety risks, difficult precision control, and insufficient adaptability. It takes 3-5 days to re-form each section of scaffolding (dismantling, transportation, and re-setting up), while it only takes 1-2 days to build a tower crane; traditional technology relies too much on tower cranes, and material lifting takes up tower crane time, slowing down the overall progress (for example, a project was delayed by 30% due to a tower crane conflict); traditional scaffolding erection and formwork dismantling require workers to operate in an unprotected high-altitude environment, with a significant risk of falling, and the scaffolding is easily affected by wind loads and has poor stability; traditional technology is difficult to adapt to the diamond-shaped tower columns of bridges or super-high-rise tapered sections. In the face of such special-shaped structures, intelligent tower cranes with good adaptability are needed. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-scenario lifting and splicing tower building system, which can control the lifting of its lifting construction unit through the jacking cross frame unit arranged on the hexagonal area, and then allow the construction operation layer, material storage layer, and maintenance demoulding layer installed on the lifting construction unit to perform cyclic climbing construction on the tower body, thereby realizing the intelligent construction of airport control towers, special-shaped tower bodies, H-shaped bridge towers, and diamond-shaped bridge towers, greatly saving construction time, and improving efficiency and tower building quality.

[0004] Another object of the present invention is to provide a multi-scenario lifting and splicing tower construction method, which can be directly applied in the existing tower construction, by dividing the tower construction scenarios into four types, namely: when applying to the construction of airport towers and single bridge towers, external cranes are used for lifting and feeding; when applying to the construction of airport towers and single bridge towers, internal lifting and self-feeding are used; when applying to the construction of double towers, H-shaped bridge towers, and diamond-shaped bridge towers, internal lifting and self-feeding or external cranes are used for lifting and feeding; when applying to any tower type, splicing and sliding tower construction is adopted, and external cranes are used for lifting and feeding. There is a corresponding tower construction method for each scenario, which effectively improves the adaptability of the entire tower construction method and is more flexible and changeable.

[0005] To further achieve the above object, the present invention adopts the following technical solutions:

[0006] A multi-scenario lifting and splicing tower building system, comprising a tower building area pre-set on the ground, the tower building area is hexagonal, and the tower body is located at the center of the tower building area;

[0007] The tower building area is provided with a group of jacking cross frame units, which includes six jacking cross frames, which are respectively distributed at the six corners of the hexagon and installed on the ground; the jacking cross frame is connected by a plurality of jacking steel trusses composed of standard sections;

[0008] The six lifting horizontal frames are provided with multiple groups of lifting construction units arranged up and down through hydraulic lifting sleeves. The lifting construction units cover the entire tower construction area through internal steel trusses to form a tower construction range;

[0009] A construction operation layer is arranged on the top of the lifting construction unit located at the uppermost layer;

[0010] The construction operation layer includes a closed protective outer ring, and a circular channel is formed on the periphery by the closed protective outer ring. The circular channel is provided with a rectangular opening for passing through the jacking steel truss; the remaining positions on the circular channel are used to be equipped with a variety of automated operation machines;

[0011] A construction channel is connected to the middle of the circular channel. The construction channel is cross-shaped and includes two vertical channels that are perpendicular to each other and connected. An oblique channel connected to the two vertical channels is arranged between each two vertical channels, so as to cover the entire construction area to the greatest extent.

[0012] Below the construction passage is a closed protection area, which is used as a specific location for operations and rises together with the construction operation floor.

[0013] Optionally, three groups of lifting construction units arranged up and down are arranged on the six lifting horizontal frames through hydraulic lifting sleeves, wherein:

[0014] The group of lifting construction units located on the top floor is used to install the construction operation layer, and workers work on the top floor with the equipment; the group of lifting construction units located on the second floor is used to store construction materials for easy access to the top floor;

[0015] A group of lifting construction units located on the third floor is used to fix the curing layer after the tower is poured.

[0016] Furthermore, it also includes two additional lifting cross frames arranged on one side of the two lifting cross frames located on one side of the tower body, the two lifting cross frames located on one side of the tower body and the two additional lifting cross frames form a rectangle, and a rectangular second external auxiliary unit is arranged on the four lifting cross frames through a hydraulic lifting sleeve;

[0017] A protective net is arranged on the periphery of the second external auxiliary unit, and a crane is also arranged at a position close to the lifting construction unit for internal construction.

[0018] Optionally, two sets of tower-building systems are connected in parallel, and two sets of bridge towers are constructed using one tower-building system respectively.

[0019] Optionally, it also includes a method of connecting two tower building systems in series, wherein the top and the upper right two jacking cross frames of a group of jacking cross frame units located on the left and the top and the upper left two jacking cross frames of a group of jacking cross frame units located on the right form an inverted trapezoidal area, and the four jacking cross frames located in the inverted trapezoidal area are provided with a trapezoidal first external auxiliary unit through a hydraulic jacking sleeve;

[0020] Symmetrically to the inverted trapezoidal area, the bottom and lower right two lifting cross frames of a group of the lifting cross frame units located on the left and the bottom and lower left two lifting cross frames of a group of the lifting cross frame units located on the right form a regular trapezoidal area, and another first external auxiliary unit is arranged on the four lifting cross frames located in the regular trapezoidal area;

[0021] The two first external auxiliary units are used for lifting and transporting construction materials. At the same time, one of the first external auxiliary units is used for replenishing materials for one of the tower building systems, and the other first external auxiliary unit is used for replenishing materials for another of the tower building systems.

[0022] Furthermore, the two upper right and lower right lifting frames in the group of lifting frame units located on the left and the two upper left and lower left lifting frames in the group of lifting frame units located on the right form a rectangular area, and a second external auxiliary unit is arranged on the four lifting frames located in the rectangular area.

[0023] Furthermore, the second external auxiliary unit is extended so that its periphery is connected to the four lifting cross frames at the upper left, lower left, upper right and lower right in a group of lifting cross frame units located on the left side and the four lifting cross frames at the upper left, lower left, upper right and lower right in a group of lifting cross frame units located on the right side, so that its coverage range is wider and the connection and lifting are more stable.

[0024] Optionally, the method further comprises deleting the overlapping middle single lifting cross frame of two adjacent groups of lifting cross frame units, and using the splicing and sliding tower construction method for any tower type;

[0025] At this time, the group of lifting cross frame units located on the left side has five lifting cross frames, namely the left end, upper left, upper right, lower left, and lower right, and the group of lifting cross frame units located on the right side has five lifting cross frames, namely the right end, upper right, upper left, lower right, and lower left;

[0026] The two groups of lifting cross frame units form a groove inside after removing the overlapping parts of the lifting cross frames. Ten lifting cross frames are provided with one or more layers of rectangular transverse steel trusses connected by a number of standard sections through hydraulic lifting sleeves.

[0027] Furthermore, the first-layer transverse steel truss is provided with three upper and lower sliding construction operation layers through a hydraulic transverse sleeve; or the third-layer transverse steel truss is provided with three upper and lower sliding construction operation layers correspondingly;

[0028] The three sliding construction operation layers are respectively a top operation layer, a middle material storage layer, and a bottom maintenance demoulding layer.

[0029] A multi-scenario lifting and splicing tower building method, using the aforementioned multi-scenario lifting and splicing tower building system, comprises the following steps:

[0030] S1. When building an airport tower or a single bridge tower and using an external crane to transport and feed materials, the height to which the jacking steel truss combination reaches is set according to the actual tower building height, and then the assembled construction steel trusses are installed on the hydraulic jacking frame according to the actual situation. The specific assembled shape and the internal reserved space are adjusted according to the actual bridge tower shape and size. The reserved space is used to install the closed protection area; the three groups of lifting construction units installed on the jacking cross frame unit are used for construction work, material storage, and closed maintenance from top to bottom, respectively. A construction operation layer is installed on the top of the top lifting construction unit. A construction passage is set on the inner side of the outer circle of the construction operation layer. Workers walk on the construction passage and carry out construction work. After the concrete pouring and steel bar binding are completed, they climb up and move the tower surface of the construction operation layer to the closed protection area below for maintenance, and then continue the repeated operation above; until the entire single tower is fully poured and maintained from bottom to top, and then the tower building machine is dismantled. It is only necessary to dismantle the top construction passage first, and the rest can be dismantled after being lowered to the ground through the hydraulic jacking frame;

[0031] S2, when applied to the construction of airport towers and single bridge towers, when internal lifting and self-feeding are adopted, the single tower construction method is the same as step S1. When feeding operation is required, no additional crane is required. When the internal several layers of lifting construction units are constantly climbing upward and in the process of construction, firstly, sufficient construction materials are stored on the second external auxiliary unit on the ground, and then the second external auxiliary unit is lifted to the vicinity of the lowest lifting construction unit by hydraulic jacking. The materials on the second external auxiliary unit are directly lifted to the lifting construction unit where the construction materials are stored internally by the crane on the second external auxiliary unit, waiting for use, and the materials are lifted and transported back and forth in this way until the construction of the entire single tower is completed;

[0032] S3. When the twin towers to be constructed are far apart, two sets of tower construction systems can be connected in parallel. The specific method is to use one tower construction system to construct each of the two sets of bridge towers. The specific structure and construction method are the same as step S1. There is no linkage, and the materials are all fed by an external tower crane.

[0033] When the twin towers to be constructed are close to each other or are H-shaped towers or diamond-shaped towers, a dual tower construction system is connected in series. When the tower construction systems on both sides are climbing and building towers, two first external auxiliary units are used to lift and feed materials synchronously, or two are used to feed materials one by one. After the vertical construction of the left and right towers above is completed, the second external auxiliary unit is raised to construct the beam between the two towers. The specific splicing shape of the steel truss inside the second external auxiliary unit also needs to be adjusted according to the actual shape of the tower beam, so that its construction area can cover the entire beam. When the vertical tower and the tower beam are constructed, the entire tower construction is completed.

[0034] S4. When applied to any tower type and an external crane is used to lift and feed materials, a combined sliding tower construction method can be adopted. The hydraulic jacking sleeve drives the transverse steel truss to move up and down to realize the vertical lifting of the sliding construction layer. The hydraulic transverse sleeve is used to achieve secondary horizontal sliding, so that the sliding construction layer is first built upward from the bottom of the bridge tower on one side. After the tower construction is completed, it slides horizontally to the bottom of the bridge tower on the other side for a second upward tower construction. After both bridge towers are completed, the sliding construction layer is slid to the middle to build the crossbeam of the H-type bridge tower until the entire bridge tower is completed.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The tower building system designed by the present invention adopts a hexagonal single-machine tower building method for the construction of airport control towers and single bridge towers. It can self-climb and build the tower body in its area from bottom to top step by step through the hexagon formed by six jacking cross frames. Because the shape of the internal construction steel trusses can be spliced ​​and adjusted, it can cope with various special-shaped towers well. It is divided into three layers, namely the top operating layer, the middle material storage layer, and the bottom closed maintenance and demoulding layer. The three layers can be synchronously climbed by the lifting construction unit.

[0037] 2. The tower building system designed by the present invention is applied to the construction of airport towers and single bridge towers. The usual method of transporting materials by crane can be adopted. However, a more efficient and safe method can also be adopted, that is, two lifting cross frames are added to form a hexagonal construction area + rectangular lifting and feeding area. Compared with the traditional tower crane transportation of materials, it can transport a large amount of materials at one time. At the same time, it is as stable as an elevator. There are anti-fall fences around it, which can effectively reduce the influence of high-altitude strong winds, vibrations, etc., and improve the safety of material transportation.

[0038] 3. The tower building system designed by the present invention has a variety of optional implementation methods when applied to the construction of double towers, H-shaped bridge towers, and diamond-shaped bridge towers, including two sets of tower building systems in parallel and two sets of tower building systems in series. As for the two sets of tower building systems in series, it can be divided into two situations: a longer second external auxiliary unit and a shorter one. It is flexible and changeable, making the entire tower building method more adaptable.

[0039] 4. The two sets of trapezoidal first external auxiliary units designed in the present invention effectively use the characteristics of the hexagon to cover the small rectangle inside the large rectangle, and use the least amount of lifting cross frames to piece together the most variable lifting and feeding and middle beam construction structures. The first external auxiliary unit can be used for feeding both the two tower building systems at the same time and each tower building system one-to-one. In addition to being used for lifting and feeding, the second external auxiliary unit can also be used as a construction operation layer to construct the beams of the bridge tower in projects where there is a need, thereby effectively improving construction efficiency.

[0040] 5. The splicing and sliding tower-building method designed in the present invention as embodiment 4 is different from the other embodiments in that it first removes the duplication of two groups of twelve hexagonal lifting cross frames and splices them into ten, so that the longer sides of the formed trough have four lifting cross frames, so that the sliding construction working layer thereon is more stable in translation, and then a group of horizontal transverse steel trusses are provided on the ten lifting cross frames through hydraulic lifting sleeves. This is a vertical lifting, and the transverse steel trusses are further horizontally slid by hydraulic transverse sleeves, so that the sliding construction working layer thereon can first be built upward from the bottom of the bridge tower on one side, and then horizontally slide to the bottom of the bridge tower on the other side after the tower building is completed for the second upward tower building. This method effectively improves the utilization rate of the entire tower-building equipment, and only requires one set of tower-building system to carry out construction work on the two vertical towers and multiple beams of the bridge tower, effectively saving the equipment installation cost and the debugging and replacement cost.

[0041] 6. The present invention integrates the formwork, climbing and protection systems into one, which can simultaneously carry out concrete pouring, maintenance and steel bar binding like an aerial building machine. At the same time, it can well cope with various tower construction needs, such as single tower construction of airport control towers, diamond-shaped tower column construction of bridges, and super-high-rise tapered section tower construction.

[0057] In order to facilitate ordinary technicians in the field to understand and implement the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the implementation examples described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0058] Embodiment 1:

[0059] A multi-scenario lifting and splicing tower building system, when applied to the construction of airport towers and single bridge towers, an external crane is used to lift and feed materials. Figure 1-2As shown, it includes the ground 0001 as the main body, and a hexagonal tower-building area is pre-set on the ground 0001. The hexagonal range covered by the hexagonal tower-building area can meet the needs of most special-shaped tower constructions. The center of the area is the tower body 0003. The hexagonal tower-building area is provided with a group of jacking cross frame units 1000. This group of jacking cross frame units 1000 includes six jacking cross frames, and the six jacking cross frames are respectively distributed at the hexagonal corners of the hexagon. Each jacking cross frame is installed on the ground 0001 through the pre-embedded anchoring components in the pre-embedded anchoring area 1001. The jacking cross frame is connected by a jacking steel truss 1002 composed of several standard sections. When the jacking operation above is completed, a temporary tower support 1003 is set between the tower body 0003 and the jacking cross frame unit 1000 to avoid tilting and instability of the tower body. For the jacking cross frame unit 1000 that still needs to be lifted, the temporary tower support 1003 may not be set. Six jacking cross frames form a group and form a hexagon. Circular lifting construction units 2000 are installed on the six jacking cross frames through hydraulic jacking sleeves 2001. The lifting construction units 2000 cover the entire hexagonal area through the internal construction steel trusses 2002, which is the entire construction range of the tower. The hydraulic jacking sleeve 2001 can realize self-jacking and lowering on the jacking steel trusses 1002 through the hydraulic system, and then continuously build the tower upward, repeating the operations of concrete pouring, curing, and lifting; a group of six jacking cross frames of a tower building system can be equipped with multiple groups of lifting construction units 2000 at the same time to realize multi-layer synchronous lifting; take the third floor as an example: a group of lifting construction units 2000 used at the top (the uppermost layer) is used to install the construction operation layer 3000, and the workers work on the top layer with the equipment; a group of lifting construction units 2000 is used on the second floor to store construction materials for easy access to the top floor; a group of lifting construction units 2000 is used on the third floor to fix the curing layer after the tower is poured.The construction operation layer 3000 is mainly composed of a closed protective outer ring installed on the top of the lifting construction unit 2000 on the uppermost layer, and a circular channel is formed on the periphery by the closed protective outer ring. The circular channel is provided with a rectangular opening for passing through the jacking steel truss 1002. The remaining positions on the circular channel can be equipped with various automated operating machines, such as concrete unloading and pouring equipment, concrete vibration equipment, small cranes, steel bar binding equipment, etc. A construction channel 3001 is also connected to the middle of the circular channel. The construction channel 3001 is in a cross shape, including two vertical channels that are perpendicular to each other and connected, and an oblique channel connected to the two vertical channels is provided between each two vertical channels, which is used to cover the entire construction area to the greatest extent, so that construction personnel can safely carry out construction work in the construction channel 3001. ; Below the construction passage 3001 is the closed protection area 3002, which is usually supported by a steel frame close to the outer periphery of the tower body. The closed protection area 3002 is fixed to the bottom of the lifting construction unit 2000 by welding steel sections. The steel frame extends below the three-story lifting construction unit 2000 and covers a certain height of the tower body. A protective plate or safety net is provided on the periphery, and a dense mesh safety net is hung inside for safety and fall prevention. A sliding template is also provided on the innermost side for molding and curing after concrete pouring, which can be lifted together with the steel frame. The area enclosed by the closed protection area 3002 is the specific location of the operation. Concrete pouring, steel bar tying and other works can be carried out in the closed protection area 3002, and finally it is used for concrete curing, and then it climbs together with the construction operation layer 3000.

[0060] Embodiment 2:

[0061] A multi-scenario lifting and splicing tower building system, when applied to the construction of airport towers and single bridge towers, adopts internal lifting and self-feeding. Figure 1 , Figure 2 , Figure 5As shown, Example 2 has all the structures in Example 1, but does not require an additional external crane to lift and feed materials, because it is more dangerous to lift materials to high altitudes by additionally configuring an external crane; in addition to a set of lifting cross frame units 1000 of the main body, two additional lifting cross frames are provided on the right side of the two lifting cross frames located on the right side of the tower body 0003, and a rectangle is formed by the two lifting cross frames located on the right side of the tower body 0003 and the two additional lifting cross frames. A rectangular second external auxiliary unit 4002 is provided on the four lifting cross frames through a hydraulic lifting sleeve 2001. The second external auxiliary unit 4002 is essentially a rectangular handling platform composed of a number of steel trusses, similar to a large elevator. Since a set of lifting cross frame units 1000 is already provided, two additional lifting cross frames are provided as It is more feasible to provide a material transportation platform, which has a protective net on the outside and a crane near the lifting construction unit 2000 for internal construction. When the internal several layers of lifting construction units 2000 are constantly climbing upward and constructing, a group of second external auxiliary units 4002 can be set under the lowest lifting construction unit 2000. Sufficient construction materials can be stored on the ground on the platform first, and then the second external auxiliary unit 4002 can be hydraulically lifted to the vicinity of the lowest lifting construction unit 2000. The materials on the platform can be directly lifted by the crane on the second external auxiliary unit 4002 to the lifting construction unit 2000 where the construction materials are stored inside, waiting for use. The materials can be lifted and transported back and forth in this way, making the material transportation of the entire tower construction system more efficient and safe.

[0062] Embodiment 3:

[0063] A multi-scenario lifting and splicing tower building system, when applied to the construction of double towers, H-shaped bridge towers, and diamond-shaped bridge towers, adopts internal lifting self-feeding or external crane lifting and feeding. Figure 3 , Figure 4 , Figure 6 shown.

[0064] When the twin towers to be constructed are far apart, two sets of tower construction systems can be connected in parallel, such as Figure 3 As shown, at this time, two groups of bridge towers are constructed using a tower construction system respectively. The specific structure and construction method are the same as those in Example 1. There is no linkage, and both are fed by external tower cranes.

[0065] When the twin towers to be constructed are close to each other or are H-shaped or diamond-shaped towers, a double tower system can be used in series, such as Figure 4 , Figure 6As shown, the main body is mainly composed of two left and right groups of lifting cross frame units 1000. It should be noted that the rightmost and leftmost ends of the two left and right groups of lifting cross frame units 1000 are composed of two lifting cross frames that can be connected into a vertical line (here used to describe the relative orientation and connection method of the two tower-building systems, and to distinguish them from the connection orientation in Example 4), while in Example 4, the leftmost and rightmost ends of the two groups of lifting cross frame units 1000 each have only one lifting cross frame; the relative positions and connection methods of the first external auxiliary unit 4001 and the second external auxiliary unit 4002 are described according to the orientations of the above two groups of lifting cross frame units 1000; the top and upper right two lifting cross frames of a group of lifting cross frame units 1000 located on the left and the top and upper left two lifting cross frames of a group of lifting cross frame units 1000 located on the right form an inverted trapezoidal area, and the four lifting cross frames located in the inverted trapezoidal area are provided with a trapezoidal The first external auxiliary unit 4001 and its symmetrical position, that is, the two lifting cross frames at the bottom and lower right of a group of lifting cross frame units 1000 on the left and the two lifting cross frames at the bottom and lower left of a group of lifting cross frame units 1000 on the right form a regular trapezoidal area. Another first external auxiliary unit 4001 is provided on the four lifting cross frames located in the regular trapezoidal area. The specific function of the first external auxiliary unit 4001 is similar to that of the second external auxiliary unit 4002 in Example 2, which is mainly used for lifting and transporting construction materials. The reason for setting up two pairs of transport platforms, in addition to the purpose of increasing the material transportation volume, can also realize one-to-one material transportation. For example, the regular trapezoid is used for material replenishment of the left tower building system, and the inverted trapezoid is used for material replenishment of the right tower building system, so that if there is a progress difference between the two groups of tower building systems, the feeding progress can be adjusted to avoid the problem of having to wait for the other side to be used up before descending to take materials;In addition to the first external auxiliary unit 4001, the two upper right and lower right lifting frames in the group of lifting frame units 1000 on the left and the two upper left and lower left lifting frames in the group of lifting frame units 1000 on the right form a rectangular area. The four lifting frames located in the rectangular area can be used to set up the second external auxiliary unit 4002. The specific method is the same as the second external auxiliary unit 4002 in Example 2. In this case, there is no need to add two additional lifting frames, which can be directly replaced by two of the group of lifting frame units 1000 on the right, further improving the utilization rate of the equipment. However, the second external auxiliary unit 4002 is not mainly used for material transportation at this time. The steel trusses provided on the second external auxiliary unit 4002 can be configured with a similar structure to the construction operation layer 300. 0 construction channel 3001, and concrete placing machine, concrete vibrator, steel bar hoist and other mechanisms are arranged around it, and the second external auxiliary unit 4002 is used as an auxiliary construction platform, which is mainly used for the construction of the beam after the vertical construction of the left and right bridge towers is completed. Therefore, the specific splicing shape of the internal steel truss also needs to be adjusted according to the actual shape of the bridge tower beam, so that its construction area can cover the entire beam. If necessary, the second external auxiliary unit 4002 can also be extended so that its periphery is connected with the four jacking cross frames of the upper left, lower left, upper right and lower right in the group of jacking cross frame units 1000 located on the left and the four jacking cross frames of the upper left, lower left, upper right and lower right in the group of jacking cross frame units 1000 located on the right, so that its coverage is wider and the connection and lifting are more stable. ;

[0066] Embodiment 4:

[0067] A multi-scenario lifting and splicing tower building system, when applied to any tower type, adopts splicing and sliding tower building, and external cranes lift and feed materials. Figure 7As shown, it is composed of two adjacent groups of jacking cross frame units 1000 with the overlapping single middle jacking cross frame deleted. Its specific orientation is that the tops of the two hexagons are edges rather than points (the right side in the figure is the top edge). At this time, there are five jacking cross frames at the left end, upper left, upper right, lower left and lower right in the group of jacking cross frame units 1000 located on the left. Therefore, the position of the jacking cross frame at the right end overlaps with the jacking cross frame at the left end of the group of jacking cross frame units 1000 located on the right and is removed. There are five jacking cross frames at the right end, upper right, upper left, lower right and lower left in the group of jacking cross frame units 1000 located on the right. The purpose of setting up this structure is that after removing the overlapping jacking cross frames, the two groups of jacking cross frame units 1000 form a groove inside, thereby realizing the maximum utilization of space. At the same time, the groove formed inside can provide a larger construction coverage area. , it can also cope well with double towers, H-shaped towers, and diamond-shaped bridge towers; the above-mentioned ten jacking cross frames are connected to a rectangular transverse steel truss 5001 composed of a number of standard sections through a hydraulic jacking sleeve 2001, and a rectangular sliding construction operation layer 5003 is installed on the steel trusses located on the two symmetrical longer sides through a hydraulic transverse sleeve 5002; the hydraulic transverse sleeve 5002 is a version of the hydraulic jacking sleeve 2001 rotated ninety degrees, which adjusts the vertical jacking hydraulic equipment to horizontal transverse movement; the specific structure of the sliding construction operation layer 5003 is similar to the construction operation layer 3000, and can also be divided into a top operating layer, a middle material storage layer, and a bottom maintenance and demoulding layer. Here, it can be a group of transverse steel trusses 5001 with three layers of sliding construction operation layers 5003, or three groups of transverse steel trusses 5001 above and below are respectively equipped with a group of sliding construction operation layers 5003.

[0068] A multi-scenario lifting and splicing tower construction method, see Figure 1-7 , which includes:

[0069] S1. First, select the tower construction range according to the shape and size of the tower to be built, and cover the tower to be built in the tower construction area 0002, then pre-embed six groups of anchoring components on the ground 0001, and then install the jacking cross frame unit 1000 on the anchoring component, set the height reached by the jacking steel truss 1002 combination according to the actual tower construction height, and then install the hydraulic jacking sleeve 2001 on the jacking cross frame unit 1000, and then install the assembled construction steel truss 2002 on the hydraulic jacking sleeve 2001 according to the actual situation. The specific assembled shape and internal reserved space are adjusted according to the actual shape and size of the bridge tower. For example, a bridge tower with a larger cross-sectional area uses more reserved space, and a bridge tower with a smaller cross-sectional area uses a smaller reserved space. The reserved space is used to install the closed protection area 3002; three groups of lifting construction units 2000 can be installed in sequence on the jacking cross frame unit 1000, and they are reasonably spaced, from top to bottom, respectively used for construction operations, material storage, and closed maintenance, and the lifting unit 2001 at the top A construction layer 3000 is installed on the top of the lowering construction unit 2000. The outer circle of the construction layer 3000 is a closed protective outer circle. The workers' working area is safely closed by an anti-fall net. A construction channel 3001 is set on the inner side of the outer circle of the construction layer 3000, on which workers can walk and carry out construction work. During the operation, various mechanical equipment on the closed protective outer circle channel are used to assist in construction. After the concrete pouring and steel bar binding are completed, the tower surface of the operation layer is moved to the closed protective area 3002 below for maintenance, and then the repeated operations above are continued; before the operation, a certain amount of construction materials can be stored on the second floor, and during the continuous upward climbing process, the construction materials can be hoisted by an external crane to the upper part for storage, and continuous construction is carried out; until the entire single tower is poured and maintained from bottom to top, the tower crane can be dismantled afterwards. It is only necessary to dismantle the top construction channel 3001 first, and the rest can be dismantled after being lowered to the ground through the hydraulic jacking frame 2001.

[0070] S2. The single-tower construction method is the same as step S1. When feeding operation is required, there is no need to configure an additional crane. By adding two additional jacking cross frames on the right side of a group of jacking cross frame units 1000, a hexagonal plus rectangular construction + feeding combination is formed. A second external auxiliary unit 4002 is set on the four jacking cross frames through a hydraulic jacking sleeve 2001. When the internal several layers of lifting construction units 2000 are constantly climbing upward and constructing, sufficient construction materials can be stored on the ground on the second external auxiliary unit 4002, and then the second external auxiliary unit 4002 is hydraulically lifted to the vicinity of the lowest lifting construction unit 2000. The materials on the second external auxiliary unit 4002 are directly lifted to the lifting construction unit 2000 where the construction materials are stored internally by the crane on the second external auxiliary unit 4002 at a short distance, waiting for use, and the materials are lifted and transported back and forth in this way until the construction of the entire single tower is completed.

[0071] S3. When the twin towers to be constructed are far apart, two sets of tower construction systems can be connected in parallel. The specific method is to use one tower construction system to construct the two sets of bridge towers respectively. The specific structure and construction method are the same as those in Example 1. There is no linkage, and the materials are all fed by an external tower crane.

[0072] When the twin towers to be constructed are close to each other or are H-shaped bridge towers or diamond-shaped bridge towers, a double tower system can be used in series to adjust the relative positions of the two hexagonal areas so that the rightmost and leftmost ends of the two hexagons are composed of two jacking horizontal frames that can be connected in a vertical line, and the top and upper right two jacking horizontal frames of a group of jacking horizontal frame units 1000 located on the left and the top and upper left two jacking horizontal frames of a group of jacking horizontal frame units 1000 located on the right are used to install the first external auxiliary unit 4. 001, located at a symmetrical position of the inverted trapezoidal area, the two lifting cross frames at the bottom and the lower right of the set of lifting cross frame units 1000 on the left and the two lifting cross frames at the bottom and the lower left of the set of lifting cross frame units 1000 on the right form a positive trapezoidal area for installing another set of first external auxiliary units 4001; the two lifting cross frames at the upper right and the lower right of the set of lifting cross frame units 1000 on the left and the two lifting cross frames at the upper left and the lower left of the set of lifting cross frame units 1000 on the right form a rectangular area The second external auxiliary unit 4002 is installed in the area. When the tower construction systems on both sides are climbing and building towers, the two first external auxiliary units 4001 can be used for synchronous lifting and feeding, or two can be used for feeding one by one. After the vertical construction of the left and right bridge towers above is completed, the second external auxiliary unit 4002 can be raised to construct the beam between the two bridge towers. The second external auxiliary unit 4002 is provided with a construction channel 3001 similar to the construction operation layer 3000. The specific splicing shape of the internal steel truss of the second external auxiliary unit 4002 The shape also needs to be adjusted according to the actual shape of the bridge tower beam so that its construction area can cover the entire beam. If necessary, the second external auxiliary unit 4002 can also be extended so that its periphery is connected to the four lifting cross frames of the upper left, lower left, upper right and lower right in a group of lifting construction units 1000 on the left and the four lifting cross frames of the upper left, lower left, upper right and lower right in a group of lifting construction units 1000 on the right, and then the beam construction is carried out. When the construction of the vertical bridge tower and the bridge tower beam is completed, the construction of the entire bridge tower is completed.

[0073] S4. When applied to any tower type and an external crane is used to lift and feed materials, a combined sliding tower construction method can be adopted. The specific tower construction system of this embodiment is different from other embodiments. It combines two groups of twelve hexagonal lifting cross frames into ten, and the formed trough has four lifting cross frames on the longer sides, so that the sliding construction operation layer on it can be translated more stably. A group of horizontal transverse steel trusses 5001 are installed on the ten lifting cross frames through hydraulic lifting sleeves 2001 to realize the up and down movement of the transverse steel trusses 5001, thereby realizing the sliding construction operation layer. The up and down lifting of the working layer 5003 is a vertical lifting, and the hydraulic transverse sleeve 5002 on the transverse steel truss 5001 realizes the secondary horizontal sliding of the slidable construction working layer 5003, so that the slidable construction working layer on it can first build the tower upward from the bottom of the bridge tower on one side, and after the tower building is completed, it can slide horizontally to the bottom of the bridge tower on the other side for the second upward tower building. After the two bridge towers are completed, the slidable construction working layer 5003 can be slid to the middle to build the crossbeam of the H-shaped bridge tower until the entire bridge tower is completed.
