Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a method for quickly constructing a cable tower steel frame and steel bar components. Background Art

[0002] In traditional technology, cable tower steel bars are usually constructed by loose binding on site. Due to the limited space and equipment available for on-site construction, it is easy to cause poor steel bar construction accuracy, high-altitude hoisting and high operation risks. With the development of modern technology, in order to further improve the level of industrialized construction of cable towers, more and more cable tower steel bars are using componentized steel bar construction technology, that is, prefabrication in factories first.

[0003] For cable towers with large inclination of the tower limbs, when the steel bar parts are connected on the tower, the overall deformation of the steel bar parts is large. In order to improve the stiffness of the steel bar parts when they are connected on the tower, it is necessary to set a rigid skeleton in the parts. For steel bar parts in the form of interlocking stirrup reinforcement, a forming process based on steel bar blocks is mostly used, that is, the stirrups are processed into steel mesh in the factory, and the steel mesh is assembled into steel bar parts, transported to the main tower, and then assembled and hoisted as a whole under the tower to form a bridge tower steel skeleton, and then subsequent formwork construction and concrete pouring are carried out. This method requires a large assembly site under the tower, so it is easily restricted by the terrain and hydrological environment, especially offshore construction, because offshore construction has transportation difficulties and a serious lack of assembly sites. In addition, the method of hoisting after the assembly under the tower is completed is also accompanied by the problem of greatly increased risks of workers working at high altitudes and mechanical equipment failures, and will correspondingly increase the construction period and project cost. Therefore, continuing to use the above construction method is not very economical and applicable for the construction of super-large bridge cable towers. Therefore, how to improve construction methods, shorten construction periods, and reduce the risks of high-altitude operations and mechanical equipment failures is a necessary scientific and technological innovation task.

[0004] At the same time, the componentization of reinforcement for large cable towers has evolved from the original coordination of reinforcement and rigid frame to the coordination of steel frame and reinforcement for the main load-bearing structure. Currently, there is little research on the overall construction method of the componentization of steel frame and reinforcement for the main tower segment, so it is necessary to carry out research on it. Summary of the invention

[0005] In order to solve the technical problems existing in the prior art, the present application provides a rapid construction method for a cable tower steel frame and steel bar components.

[0006] The present invention provides a tower steel frame and steel bar componentized rapid construction method using the following technical solutions:

[0007] A method for rapid construction of a cable tower steel frame and steel bar components, comprising the following steps:

[0008] S1: Use construction steel to weld and assemble the steel frame to form a frame structure;

[0009] S2: Cut out the channel steel support plate and fix the channel steel support plate on the tire frame by a clamp;

[0010] S3: Use the channel steel support plate on the tire frame to assemble the limit frame and steel bars;

[0011] S4: Weld the assembled steel bars and the limit frame to the steel frame, and tie the steel bars in some areas of the inner cavity;

[0012] S5: The steel frame and the steel bars are hoisted as a whole to the corresponding position of the main tower through the hanger and the lifting lugs welded on the steel frame. Then the steel frame is welded on the main tower, the steel bars are connected and concrete is poured.

[0013] Preferably, in S1, when the steel frame is welded and assembled using construction steel, the steel frame is divided into six first area sheets, including a long sheet area B, a short sheet area A, and side sheets C1, C2, D1, and D2. After each first area sheet is manufactured individually, the segments are assembled as a whole.

[0014] Preferably, in S3, if the number of layers of steel bars is one layer, the first limit opening plate, the first limit reinforcing vertical plate and the limit end plate need to be welded on the channel steel support plate in sequence, and then the steel bars are first fed into the notch of the first limit opening plate, and the steel bars are clamped by the limit end plate and then fixed with wire ties.

[0015] Preferably, in S3, if the number of layers of steel bars is two, the first limiting opening plate, the first limiting reinforcing vertical plate, the second limiting opening plate, the second limiting reinforcing vertical plate and the limiting end plate need to be welded on the channel steel support plate in sequence, and then the first layer of steel bars is fed into the groove of the first limiting opening plate, and the first layer of steel bars is clamped by the second limiting reinforcing vertical plate and then fixed with wire, and then the second layer of steel bars is fed into the groove of the second limiting opening plate, and the second layer of steel bars is clamped by the limiting end plate and then fixed with wire.

[0016] Preferably, within each first regional sheet, the steel bars and the limiting framework are further divided into two second regional sheets according to the inner and outer sides.

[0017] Preferably, the construction steels are all angle steels, and the construction steels are divided into vertical bars, cross bars, vertical diagonal braces and horizontal diagonal braces. The cross bars are used to connect the steel skeleton horizontally. Two cross bars are arranged in parallel on the structure, and the cross bars are welded to the inner side of the outermost flange plate of the steel skeleton. The horizontal diagonal braces are used to connect the horizontal "W"-shaped structure between the cross bars. The vertical diagonal braces are used to connect the steel skeleton vertically and overlap the cross bars at both ends. The shape after connection is also "W"-shaped. The vertical bars are used in three positions, including: the vertical reinforcement position between the construction steels in areas C1 and C2, the connection position of area D close to area B, and the connection position between the intersection of area C and area D.

[0018] Preferably, the channel steel support plate is divided into two types: connected to the steel frame or connected to the cross bar.

[0019] Preferably, in step S4, the temporary support includes an ear plate support, a steel pipe, an inner support ear plate, a bolt, and an outer support ear plate. The steel pipe is divided into two pieces, and the two steel pipes can be interlocked with each other. To facilitate the operation of the pressure rod of the screw jack, an oblong hole is opened at one end of the outer steel pipe close to the ear plate support. The temporary support is installed vertically in two layers in the steel frame, and one is arranged on each opposite side in the horizontal direction.

[0020] Preferably, in step S5, in order to prevent the segment from tilting as a whole, the segment needs to be fine-tuned and adjusted by a jacking device, and a triangular stable structure is formed by modifying the temporary support and installing a second temporary support between the clamp and the first-layer ear plate support of the previous segment of the tower column to form a stable jacking force output end, and then the segment is driven by the first-layer temporary support to return to its overall linear position.

[0021] Preferably, during the rotation and extension of the temporary support, the inner and outer steel pipes are separated, the screw jack is placed inside the outer steel pipe, and a steel pipe tube with the same model as the inner steel pipe is placed inside the outer steel pipe. The steel pipe tube is located on the upper side of the screw jack, and the length of the steel pipe tube plus the lifting length of the screw jack should meet the adjustment length of the segment.

[0022] The beneficial effects of the present invention are:

[0023] 1. The steel skeleton of the main load-bearing structure is combined with the construction steel to form a frame. The steel bars are attached to the steel skeleton through the limit skeleton. Finally, the main tower segment steel skeleton and steel bars are componentized. The whole is hoisted and installed, and the segment is fine-tuned through the modification of matching parts and temporary supports. Compared with the traditional steel bar component construction method, it alleviates the difficulties of offshore construction and transportation and the serious lack of assembly sites on site, and also reduces the risks of high-altitude operations and mechanical equipment failures.

[0024] 2. Compared with the traditional positioning and installation method, the overall hoisting of steel skeleton and steel bars reduces the complexity of construction process and the chaos on site, greatly shortens the construction period, and realizes the efficient, accurate and safe installation of special-shaped steel skeleton and steel bars.

[0042] The following will be combined with the attached Figure 1 -Attached Fig.16 The present invention is further illustrated by the following embodiments.

[0043] This embodiment discloses a rapid construction method for a cable tower steel frame and steel bar components.

[0044] The rapid construction method of the cable tower steel frame and steel bar componentization includes the following steps:

[0045] S1: The tower limb of the cable tower is divided into multiple segments. First, the steel frame 1 of the tower limb segment is welded and assembled using the construction steel 2 to form a frame structure. That is, the construction steel 2 is used to connect the single steel frame 1 into a frame-shaped steel frame 1, such as Figure 5 As shown. In this embodiment, the rods of the construction steel 2 are sandblasted and painted before being transported to the vertical assembly site for welding and assembly. Each segment of the tower limb is divided into a number of first area sheets, including the A area, C1 area, D1 area, B area, D2 area and C2 area connected end to end in sequence, as shown in FIG. Figure 4 In the welding and assembling process, the steel frame 1 and the construction steel 2 of each first area sheet are welded and assembled separately, and then different first area sheets are welded and assembled, and finally assembled to form a frame structure.

[0046] S2: Fix the channel steel support plate 7 on the tire frame 11 according to the angle between the steel frame 1 and the limiting frame 6. Specifically, first cut the channel steel support plate 7 with a corresponding inclination according to the angle between the steel frame 1 and the limiting frame 6, and then fix multiple channel steel support plates 7 on the tire frame through a clamp.

[0047] S3: Assemble the limiting frame 6 and the steel bars 8. In this embodiment, there are two fixing methods according to the number of layers of steel bars 8: if the number of layers of steel bars 8 is one, the first limiting opening plate 61, the first limiting reinforcing vertical plate 62 and the limiting end plate 63 need to be welded on the channel steel support plate 7 in sequence, and then the steel bars 8 are first fed into the notch of the first limiting opening plate 61, and the steel bars 8 are clamped by the limiting end plate 63 and then fixed with wire ties; if the number of layers of steel bars 8 is two, the first limiting opening plate 61, the first limiting reinforcing vertical plate 62, the second limiting opening plate 64, the second limiting reinforcing vertical plate 65 and the limiting end plate need to be welded on the channel steel support plate 7 in sequence, and then the first layer of steel bars 8 are first fed into the notch of the first limiting opening plate 61, and the first layer of steel bars 8 are clamped by the second limiting reinforcing vertical plate 65 and then fixed with wire ties, and then the second layer of steel bars are fed into the notch of the second limiting opening plate 64, and the second layer of steel bars 8 are clamped by the limiting end plate 63 and then fixed with wire ties. The inclination angle of the second position-limiting reinforcing vertical plate 65 is slightly greater than the inclination angle of the steel bar 8 so that the steel bar 8 can be clamped, and finally the position-limiting frame 6 is tied and connected with the steel bar 8 by using stirrups. In this embodiment, since the first position-limiting opening plate 61 is in an upward opening state on the tire frame, the steel bar 8 can be directly lifted manually to the top of the opening of the first position-limiting opening plate 61 and fed vertically.

[0048] S4: The assembled steel bars 8 and the limiting frame 6 are welded to the steel frame 1, and the steel bars 8 in the inner cavity of the steel frame 1 are tied at the same time. After the steel bars 8 and the limiting frame 6 are assembled, they are hoisted to the corresponding position of the steel frame 1 and the cross bar 24 by a crane for welding and reinforcement. In particular, the limiting frame 6 and the tied steel bars 8 are welded on site in area E and area F, and the welded limiting frame 6 and the tied steel bars 8 are connected by stirrups.

[0049] S5: Fig.13 As shown, the steel frame 1 and the steel bars 8 are hoisted as a whole to the corresponding position of the main tower through the hanger 10 and the lifting lugs 12 welded on the steel frame 1, and then the steel frame 1 is welded, the steel bars 8 are connected, and concrete is poured, and the construction is cyclically carried out until the tower column is completed. In this embodiment, after the steel frame 1 and the steel bars 8 are hoisted as a whole and positioned by the limit device, welding, bolting or bolt-welding combination can be used to connect the steel frames 1 of different tower segments, and then the stirrups and bracing bars at the connection positions of different tower segments are connected, and finally concrete is poured. The subsequent segments can be constructed in a cyclic manner.

[0050] In one embodiment, in step S1, the cross-sectional shape of the profiled steel skeleton 1 is divided into three types: "king" character plus a horizontal line, "king" character shape, and "I" character shape. The construction profiled steel 2 are all angle steels, and the construction profiled steel 2 are divided into vertical rods 22, horizontal rods 24, vertical diagonal braces 21, and horizontal diagonal braces 23. Among them, the horizontal rod 24 is used to connect the profiled steel skeletons 1 horizontally. Two horizontal rods 24 are arranged in parallel structurally, and the horizontal rod 24 is welded to the inner side of the outermost flange plate of the profiled steel skeleton 1. The horizontal diagonal brace 23 is used to connect the "W" - shaped structure horizontally between the horizontal rods 24. The vertical diagonal brace 21 is used to connect the profiled steel skeletons 1 vertically and is lapped with the two end horizontal rods 24. The shape after connection is also "W" - shaped. The vertical rod 22 is mainly used in three positions, including: the vertical strengthening position between the construction profiled steels 2 in areas C1 and C2, the connection position of area D close to area B, and the connection position between the intersection of area C and area D. Further, referring to Fig. 9 , in this embodiment, the channel steel pallets 7 are divided into two types, one is connected to the profiled steel skeleton 1 and the other is connected to the horizontal rod 24.

[0051] In one embodiment, in step S1, the welding of the profiled steel skeleton 1 and the construction profiled steel 2 needs to be welded in multiple first - area sheets and then assembled into a circular whole. Each single tower limb segment is divided into six first - area sheets, including the long - sheet area B, short - sheet area A, and side sheets C1, C2, D1, D2. When the side of the profiled steel skeleton 1 is straight, two layers of construction profiled steels 2 are arranged in each area; when the side projection of the profiled steel skeleton 1 is curved, one more layer of construction profiled steel 2 is added at the center position of the section elevation in areas C1, C2, D1, D2, both to control the shape of the curved steel bars 8 and to prevent the protruding curved steel bars 8 from encroaching on the concrete protective layer, while in areas A and B at the center position of the section elevation, only the connection of the horizontal diagonal brace 23 and the vertical diagonal brace 21 is used for strengthening. After each first - area sheet is manufactured separately, the overall segment assembly is carried out.

[0052] In one embodiment, two types of jigs are required during the component - based construction of the profiled steel skeleton 1. One is the jig for positioning the profiled steel skeleton 1, and the other is the jig 11 for installing the steel bars 8. The jig structure for the profiled steel skeleton 1 is relatively complex and should be equipped with devices for positioning, limiting, guiding, and angle adjustment of the profiled steel skeleton 1 to ensure that the angles and box - opening positions of each sheet can be inspected, adjusted, and controlled during the segment assembly process, and to guarantee the overall manufacturing accuracy of the profiled steel skeleton 1 and the steel bar 8 segments. The jig 11 for the steel bars 8 only needs to be able to clamp the channel steel pallets 7 and have a certain adjustment ability according to the change in the distance between the channel steel pallets 7 and the limiting skeleton 6.

[0053] In one embodiment, as Figure 7-Figure 9As shown, the limiting frame 6 is divided into two types according to the number of layers of vertical steel bars 8. The single-layer steel bars 8 are suitable for the combination of the first limiting opening plate 61, the first limiting reinforcing vertical plate 62, and the limiting end plate 63. The double-layer steel bars 8 are additionally provided with the second limiting opening plate 64 and the second limiting reinforcing vertical plate 65 on the basis of the single layer. The first limiting opening plate 61 and the second limiting opening plate 64 are mainly used for controlling the spacing of the steel bars 8, limiting the position, and bearing the load of part of the steel bars 8. The first limiting reinforcing vertical plate 62 and the second limiting reinforcing vertical plate 65 are mainly used for limiting the position of the steel bars 8 and bearing the load of part of the steel bars 8. The limiting end plate 63 is mainly used for limiting the position.

[0054] In one embodiment, the first position-limiting reinforcement vertical plate 62 and the second position-limiting reinforcement vertical plate 65 are the main components of the position-limiting frame 6 to bear the load of the steel bar 8, and also serve as the reference and position limit when the steel bar 8 is installed and positioned. The two types of reinforcement vertical plates can well bear the load of the steel bar 8, and the inclination angle of the second position-limiting reinforcement vertical plate 65 is slightly larger than the inclination angle of the steel bar 8 so that it can clamp the steel bar 8, so that it has the function of position limit and reference.

[0055] In one embodiment, within each first area sheet, the steel bars 8 and the limiting frames 6 can be further divided into two second area sheets according to the inner and outer sides. Two points are worth noting: first, according to the convenience of on-site construction, the steel bars 8 and the limiting frames 6 of C1 and D1, C2 and D2 can be merged into one second area sheet according to the inner and outer sides for construction; second, area E and area F of the second sheet area on the inner side of the segment are special areas, and the limiting frames 6 of area E and area F are welded separately later, and the steel bars 8 are tied separately later.

[0056] In one embodiment, in step S4, Figure 11-Figure 12As shown, in order to ensure the rigidity of the steel frame 1 during the subsequent hoisting, it is necessary to install the temporary support 9. This step is considered whether to install according to the strength of the steel frame 1 of different sections. The temporary support 9 is set as a retractable structure to adapt to the construction of the entire main tower segment, and is removed after the segment is hoisted. The temporary support 9 includes an ear plate support 91, a steel pipe 92, an inner support ear plate 93, a bolt 94, and an outer support ear plate. The steel pipe 92 is divided into two pieces, and the two steel pipes 92 can be interlocked with each other and the diameter difference is not much. In order to facilitate the operation of the pressure rod 151 of the screw jack 15, the outer steel pipe 92 has an oblong hole near the end of the ear plate support 91. The temporary support 9 is installed vertically in two layers in the steel frame 1, and one is arranged on each of the opposite sides in the horizontal direction. In order to avoid interference with the steel bar 8, the ear plate support 91 is placed vertically, one is connected to the steel pipe 92, and the other is welded to the flange plate of the steel frame 1, and the two are connected by a pin. The two steel pipes 92 are processed as follows at the contact position: the inner steel pipe 92 is welded with inner support ear plates 93 on both sides, and the outer steel pipe 92 is opened on both sides according to the width of the inner support ear plates 93, and the outer support ear plates are welded. Both support ear plates have oblong holes. Later, according to the change of the spacing of the steel frame 1, bolts 94 can be passed through the oblong holes for connection and clamping to meet the requirements of the main tower hoisting at various stages. In order to facilitate the operation of the compression rod 151 of the screw jack 15, an oblong hole is opened at the end of the outer steel pipe 92 near the ear plate support 91, and the oblong hole position is reinforced by a plate. In the subsequent fine-tuning process, the compression rod 151 is inserted through the oblong hole to perform the jacking operation of the screw jack 15.

[0057] In one embodiment, in step S5, in order to prevent the segment from tilting as a whole, the segment needs to be fine-tuned and adjusted by a lifting device. At this time, a triangular stable structure can be formed by modifying the temporary support 9 and installing a second temporary support 16 between the hoop 13 and the first-layer ear plate support 91 of the previous segment of the tower column to form a stable lifting force output end, and then the segment is driven by the first-layer temporary support 9 to return to its original position. The fine-tuning process is achieved through the following steps:

[0058] S51: Pull out the pin of the ear plate support 91 of the second temporary support 9 on the inclined side of the segment, and rotate downward by a certain angle based on the ear plate support 91 of the second temporary support 9 to make room for subsequent operations;

[0059] S52: Loosen the bolts 94 of the second-layer temporary support 9 to separate the inner and outer steel pipes 92, place the screw jack 15 at the bottom of the inner cavity of the outer steel pipe 92, and insert the pressure rod 151 through the oblong hole to use it as a source of lifting force.

[0060] S53: Place a steel tube 14 that is consistent with the model of the inner steel tube 92 inside the outer steel tube 92, with the lower part of the steel tube 14 in contact with the core rod of the screw jack 15, and the upper part close to the outer steel tube 92; the steel tube 14 is cross-stiffened at both ends with a stiffening plate and sealed with a cover plate to strengthen the structure. The length of the steel tube 14 plus the lifting length of the screw jack 15 should meet the adjustment length of the segment.

[0061] S54: Tighten the bolts 94 of the second-layer temporary support 9 and install them on the first-layer ear plate support 91 of the previous construction section of the tower column.

[0062] S55: Install a second temporary support 16 between the clamp 13 and the ear plate support 91 on the other side of the first layer of the previous construction segment of the tower column to form a triangular stable structure and serve as a basis for segment fine-tuning. Here, the clamp 13 is half, and the ear plate support 91 is welded on it. The inner side of the clamp 13 is similar in size to the outer side of the steel pipe 92, and is connected to the inner support ear plate 93 and the outer support ear plate by bolts 94.

[0063] S56: The higher side steel frame 1 is lifted by the screw jack 15 of the fine-tuning device, and then the lower side steel frame 1 is driven by the first layer of temporary support 9 to return the overall linear shape of the segment to its original position.

[0064] S56: Weld the steel frame 1, connect the steel bars 8 and pour concrete, and repeat the construction until the tower column is completed.

[0065] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.

The steel pipe (92) is divided into two pieces, and the two steel pipes (92) can be interlocked. In order to facilitate the operation of the pressure rod (151) of the screw jack (15), an oblong hole is opened at one end of the outer steel pipe (92) close to the ear plate support (91). The temporary support (9) is installed vertically in two layers in the steel frame (1), and one layer is arranged on opposite sides in the horizontal direction.

9. A method for rapid construction of a cable tower steel frame and steel bars as described in claim 8, characterized in that: In step S5, in order to prevent the segment from tilting as a whole, the segment needs to be fine-tuned and adjusted by a lifting device. By modifying the temporary support (9) and installing a second temporary support (16) between the clamp (13) and the first-layer ear plate support (91) of the previous segment of the tower column, a triangular stable structure is formed to form a stable lifting force output end. After that, the segment is driven by the first-layer temporary support (9) to return to its original linear position.

10. A method for rapid construction of a cable tower steel frame and steel bar components according to claim 9, characterized in that: During the rotation and extension of the temporary support (9), the inner and outer steel pipes (92) are separated, the screw jack (15) is placed inside the outer steel pipe (92), and a steel pipe tube (14) of the same model as the inner steel pipe (92) is placed inside the outer steel pipe (92). The steel pipe tube (14) is located on the upper side of the screw jack (15), and the length of the steel pipe tube (14) plus the lifting length of the screw jack (15) should meet the adjustment length of the segment.
