[0040] The embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this disclosure, and should not be construed as limiting this disclosure.

[0041] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0042] The steel reinforcement segment assembly jig provided in this disclosure can be used to assemble steel reinforcement segments of tower columns with gradually changing cross-sections. To better describe the flexible adaptability of the assembly jig to the assembly requirements of steel reinforcement segments of tower columns with gradually changing cross-sections, an example of a bridge construction structure that can apply the assembly jig provided in this disclosure is described below. It should be understood that this structure is only an example and is not intended to limit the scope of this disclosure.

[0043] Taking the portal-style pylon of a certain bridge as an example, such as Figures 9 to 14 As shown, the tower column has a rectangular cross-section with rounded chamfers, and the reinforcing bars are arranged in two concentric rings. Among them, as... Figures 11 to 13 As shown, the cross-sections are, in order, the bottom cross-section, the middle cross-section, and the top cross-section of the tower column. For example, the bottom cross-section has dimensions of 10m × 8m and an inner cavity dimension of φ3.5m; the middle cross-section has a length that gradually changes within the range of 10-8m, a width of 8m, and an inner cavity dimension of φ6m; the top cross-section has dimensions of 8m × 8m and an inner cavity dimension of 2 × 1.8m. In one example, the cross-section of a certain steel reinforcement segment is as follows... Figure 14 As shown, it includes an outer ring of main reinforcement 21, an inner ring of main reinforcement 22, and a steel cylinder 23. Optionally, the spacing between the main reinforcement bars is 15cm, and a permanent steel cylinder is provided on the inner side of the tower column, which can be used as the inner formwork of the main tower during construction. It should be noted that the above specific values ​​are only an example and can be varied according to actual conditions. This disclosure does not limit the specific values.

[0044] The following is combined Figures 1 to 10 The specific structure of the assembly jig for the steel bar segments provided in the embodiments of this disclosure will be described.

[0045] Specifically, the assembly jig includes at least one jig unit, each jig unit being composed of a plurality of components 11 connected together, and at least some of the components being movable parts. For example, such as... Figure 1 As shown, component 11 can move horizontally to form a frame unit that matches the cross-sectional dimensions of the steel reinforcement segment. The connection position of the connecting components 11 varies depending on the cross-sectional size of the assembled steel reinforcement segment at its height on the tower column.

[0046] In this embodiment of the disclosure, considering that the tower column has a gradually changing cross-section, in order to better adapt to the assembly requirements of the steel reinforcement segments, the assembly jig is set to a component 11 assembly mode. As the cross-section of the tower column changes, at least one component 11 can be moved horizontally to connect with other components 11. For example, as... Figure 1 As shown, the components 11 on the left and right sides can be pushed inward, and / or the components 11 on the top and bottom sides can be pushed inward. This assembly jig can flexibly adapt to the assembly requirements of steel bar segments with gradually changing cross-sections in tower columns. It eliminates the need to re-lay out fixed assembly jigs for steel bar segments with different cross-sectional dimensions, which helps improve the efficiency and accuracy of steel bar segment assembly. Furthermore, the same component 11 can be reused under different assembly requirements, which helps reduce construction costs.

[0047] In one example, the length of the component forming the long side of the frame unit is set according to the longest length of the tower column cross-section, and the length of the component forming the short side of the frame unit is set according to the longest width of the tower column cross-section. For example, for the above-mentioned portal-shaped cable tower, component 1 with a side length of 10m and component 2 with a side length of 8m can be used as the foundation. When adapting to changes in cross-sectional dimensions later, the position of the components can be moved to adapt to the assembly requirements of the steel reinforcement segments to be assembled.

[0048] In a feasible embodiment, when the tower column is a portal cable tower column, the assembly jig includes two symmetrically arranged jig units. The inner cavity cross-sectional dimensions of the two jig units are the same, and they can be used to assemble the left and right steel reinforcement segments located at the same height of the tower column. This embodiment of the present disclosure, by symmetrically arranging two jig units, allows for the simultaneous assembly of the left and right steel reinforcement segments located at the same height of the tower column, which is beneficial to improving the accuracy and efficiency of steel reinforcement segment splicing.

[0049] Optional, such as Figure 1 As shown, two symmetrically arranged jig units share the same component 11, while other components are movable and detachably connected. For example, the shared component 11 between the two symmetrically arranged jig units can be a fixed component. Other components 11 move towards the fixed component based on the cross-sectional dimensions of the steel reinforcement segment to be assembled. After moving to the appropriate position, the two adjacent components are connected in a detachable manner (such as bolt connection, snap-fit ​​connection, etc.).

[0050] In one feasible embodiment, in order to maintain the uniformity of the bottom of the steel bar segments, such as forming a uniform horizontal plane or a uniform slope, the assembly jig also includes a base 12 located at the bottom of the jig unit. The base 12 can be used for leveling so that the bottom of the jig unit is at a uniform horizontal elevation.

[0051] Optionally, the base 12 includes a concrete leveling layer 123, a steel layer 122, and a steel plate layer 121 stacked from bottom to top. The elevation of the base 12 is as follows: Figure 2 As shown, the plane of the base 12 is as follows Figure 3 As shown, when the base 12 is combined with the frame unit, it presents the following appearance: Figure 4 The structure shown.

[0052] In one example, the concrete leveling layer 123 can be constructed by pouring concrete on the assembly jig site. The base 12 can be laid on the same horizontal plane by pouring an approximately 10cm thick C30 concrete foundation, on which I20 steel bars are arranged, and a 2cm thick steel plate is fully laid on the surface of the steel bars.

[0053] In one feasible embodiment, according to the variation law of the steel reinforcement in the tower column section, limiting measures can be set on the base 12 of the assembly jig before the steel reinforcement segments are assembled. By setting up the limiting measures, the efficiency and accuracy of the steel reinforcement segment assembly can be improved.

[0054] Optionally, a first limiting member 13 can be arranged on the base 12, and the position of the first limiting member 13 on the base 12 corresponds to the position of the first reinforcing bar fixed in the assembled reinforcing bar segment. For example, the first limiting member 13 can be arranged on the steel plate layer 121 of the base 12, such as by welding and fixing a steel pipe on the steel plate layer 121 as the first limiting member 13.

[0055] Optionally, a second limiting member 14 can be arranged on the base 12. The position of the second limiting member 14 on the base 12 corresponds to the position of the second reinforcing bar in the assembled reinforcing bar segment, which exhibits a regular change. For example, the second limiting member 14 can be arranged on the steel plate layer 121 of the base 12. For instance, a slotted steel plate can be arranged on the steel plate layer 121, and the vertical structure of the slotted steel plate is as follows... Figure 6 As shown, different sizes and shapes of slotted steel plates can be used to arrange the assembly frame at different positions.

[0056] Optionally, the location information of the stiffening frame column in the assembled steel reinforcement segment can be marked on the base 12. This location information can help quickly locate the position of the stiffening frame column, accelerating the assembly efficiency and accuracy of the steel reinforcement segment. For example, based on this location information, detachable limiting components, such as components with a raised effect, can be arranged on the steel plate layer 121 of the base 12 to assist in quickly locating the stiffening frame column during the assembly of the steel reinforcement segment. In one example, the location information can be marked on the steel plate layer 121 of the base 12 using an erasable material to facilitate positioning in the current stage and adjustments in subsequent stages.

[0057] For example, such as Figure 5 and Figures 11-13As shown, in the construction of the same bridge, the cross-section of the tower column gradually decreases with increasing height. Although the cross-sectional size of the reinforcing bar segments differs at different heights, there are some fixed reinforcing bar positions. Therefore, for the fixed reinforcing bar positions (the first reinforcing bar position), steel pipes for fixing the reinforcing bars can be welded to the base 12. For the parts where the reinforcing bar positions change regularly (the second reinforcing bar position), positioning slot steel plates are used to fix them to the base 12 according to the changes in the reinforcing bars of each tower column segment. This can effectively ensure the uniformity of the main reinforcement spacing and improve the efficiency and accuracy of the reinforcing bar segment assembly. In addition, the stiffening frame columns used for tying the tower column reinforcing bars can be marked and defined in advance on the base 12 according to the tower column construction segments.

[0058] In one feasible embodiment, the components 11 used to assemble the assembly frame can be made of structural steel. Optionally, square steel pipes (such as □100×100×5mm square steel pipes) can be used to arrange the columns, channel steel (such as [8 channel steel]) can be used to arrange the horizontal bracing, and cylindrical steel pipes (such as Φ48×2.5mm steel pipes) and protective netting can be used to arrange the fence. Figure 7 and Figure 8 As shown, the arrangement of component 11 facilitates operation by construction personnel.

[0059] Optionally, several operating platforms can be arranged in layers based on a preset height (e.g., 2m) (e.g., using 8mm checkered steel plates). To facilitate operation by construction personnel, ladders 111 can be installed between the operating platforms. When three layers of operating platforms are arranged, ladders 111 can be installed between adjacent layers. In one example, to improve the convenience of construction personnel and reduce the cost of setting up the assembly frame, ladders can be installed in the components 11 shared between adjacent frame units.

[0060] The steel reinforcement segment assembly jig provided in this embodiment can be used to assemble steel reinforcement segments of tower columns with gradually changing cross-sections. Specifically, the assembly jig includes at least one jig unit, each jig unit being composed of several components 11 connected together, and at least some of the components 11 are movable parts. Furthermore, the connection position of the connecting components 11 varies depending on the cross-sectional size of the assembled steel reinforcement segment at its height on the tower column. The assembly jig provided in this embodiment is a component that flexibly combines several components 11, adapting to the assembly requirements where the cross-section of the steel reinforcement segments varies in the same bridge construction. It allows for flexible combination, which is beneficial for improving the efficiency and accuracy of steel reinforcement segment assembly.
