Description

Technical Field

[0001] The invention relates to the field of arch bridge construction, and in particular to an elastic connecting piece and an arch rib assembling method. Background Art

[0002] During the assembly and construction of the main arch rib segments of the arch bridge, hoisting equipment is generally used to hoist the pre-assembled arch rib segments. Since the arch rib segments are suspended and aligned, they need to be reciprocated to move to the ideal design position. After the adjustment is completed, they are welded together with the installed arch rib segments, and then they are pulled with buckles to prevent the arch rib segments from moving.

[0003] In the above installation method, the lifting equipment cannot be unhooked before the welding is completely completed. The lifting equipment can only be released after the welding is completed. The utilization efficiency of the lifting equipment is low. During this period, the lifting equipment cannot be used for other construction operations, which increases the construction cost. At the same time, the shaking of the lifting equipment during the welding process may cause the displacement of the welded arch rib segments, resulting in installation errors. When there are slight lateral and vertical errors in the assembly of the arch ribs, the arch rib segments with lateral and vertical deviations can only be forcibly pulled together when the arch bridge is closed, resulting in excess secondary stress inside the arch bridge, which is not conducive to structural safety. Summary of the invention

[0022] In step S2, aligning and fixing the friction steel plate B with the friction steel plate A includes the following steps: using a lifting device to move the arch rib segment closer to the front arch rib segment; when any connection hole B of the rear arch rib segment is aligned with the corresponding connection hole A, fix it with a punch, slowly move the two arch rib segments, use high-strength bolts to fix the remaining connection holes B and connection holes A, remove the punch and replace them with high-strength bolts.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] An elastic connector is used to assist in splicing the front arch rib segment 50 and the rear arch rib segment 51 connected end to end. The front arch rib segment 50 and the rear arch rib segment 51 are connected to form a seam 53, and the elastic connector is connected across the seam 53. Figure 6 .

[0042] like Figure 1 As shown, the elastic connector includes an elastic component 1 and a matching component 2 , and the elastic component 1 includes a fixed steel plate A11 and an elastic matching component 12 .

[0043] like Figure 3 As shown, the elastic matching component 12 is a rectangular cylinder, which includes two pairs of cylinder walls, one pair of which is an elastic steel plate 122 and a friction steel plate A123 that are relatively parallel and spaced apart. The two side end surfaces of the fixed steel plate A11 are respectively vertically connected to the outer side surface of the elastic steel plate 122 and the front arch rib segment 50 on one side of the seam 53. The elastic component 1 also includes a plurality of adjustment bolts 121 that penetrate the elastic steel plate 122, and the adjustment bolts 121 are used to adjust the compression amount of the elastic steel plate 122.

[0044] like Figure 4 As shown, the matching assembly 2 comprises a fixed steel plate B21 and a friction steel plate B22, and the two side end surfaces of the fixed steel plate B21 are respectively vertically connected to the friction steel plate B22 and the rear arch rib segment 51 on the other side of the joint 53. The friction steel plate A123 is aligned and fixed with the friction steel plate B22.

[0045] The fixing steel plate A11 of the elastic component 1 and the fixing steel plate B21 of the matching component 2 are respectively arranged across the two sides of the joint 53 .

[0046] In this embodiment, in the initial state, the elastic steel plate 122 of the elastic connector is in a natural state, neither stretched nor compressed; when the cantilever end 54 of the rear arch rib segment 51 is offset relative to the designed position during the installation process, the elastic steel plate 122 is compressed by adjusting the multiple adjustment bolts 121, and the compression amount of the elastic steel plate 122 is changed with the change of the cantilever end 54. The multiple elastic connectors at the joint 53 are adjusted in coordination to make the cantilever end 54 of the rear arch rib segment 51 reach the designed position.

[0047] like Figure 2As shown, the elastic matching component 12 also includes two transfer steel plates 124, each transfer steel plate 124 is respectively connected to the side of the elastic steel plate 122 and the friction steel plate A123, and the two transfer steel plates 124, the elastic steel plate 122 and the friction steel plate A123 are enclosed to form a rectangular cylinder with a accommodating space 120.

[0048] like Figure 5 As shown, the elastic steel plate 122 includes two frame plates 1223 and a plurality of V-shaped spring plates 1221. The two frame plates 1223 are arranged in parallel and spaced apart, and the plurality of V-shaped spring plates 1221 are clamped between the two frame plates 1223. The elastic steel plate 122 is provided with a plurality of adjustment holes 1224, and the adjustment bolts 121 are matched and penetrated through the adjustment holes 1224 one by one. The use of a plurality of adjustment bolts 121 can achieve the purpose of precise adjustment.

[0049] In this embodiment, the friction steel plate A123 is provided with a plurality of connection holes A1222, and the friction steel plate B22 is also provided with a plurality of connection holes B2202. The connection holes A1222 and the connection holes B2202 are located in a one-to-one correspondence and are fixed by high-strength bolts 3.

[0050] like Figure 2 As shown, the heads of the adjusting bolt 121 and the high-strength bolt 3 are both located in the accommodating space 120, and the accommodating space 120 can accommodate a torque wrench. The installation and fixing of the adjusting bolt 121 and the high-strength bolt 3 are both achieved with the assistance of a torque wrench.

[0051] In this embodiment, the fixing steel plates A11 of the elastic component 1 and the fixing steel plates B21 of the matching component 2 are both two pieces, and the two fixing steel plates A11 are arranged in parallel with each other, and each fixing steel plate A11 and a fixing steel plate B21 are located in the same plane. Each elastic connector has two fixing steel plates A11 or fixing steel plates B21 on both sides of the joint 53, so that the connection between the elastic connector and the front arch rib segment 50 or the rear arch rib segment 51 is more firmly established.

[0052] Preferably, the plurality of adjusting bolts 121 are located between the two fixed steel plates A11; and the plurality of high-strength bolts 3 are located between the two fixed steel plates B21.

[0053] In another embodiment, the fixed steel plate A11 of the elastic component 1 and the fixed steel plate B21 of the matching component 2 can also be one piece. In this case, the fixed steel plate A11 is fixed to the middle of the side wall of the elastic steel plate 122; the matching component 2 is fixed to the middle of the side wall of the friction steel plate B22, and the fixed steel plate A11 and the fixed steel plate B21 are located in the same plane.

[0054] In this embodiment, the fixed steel plate A11 and the fixed steel plate B21 have the same shape and size, and are both rectangular aluminum alloy plates with two diagonal cuts. The planes where the two side end surfaces of the fixed steel plate A11 connecting the elastic steel plate 122 and the front arch rib segment 50 are located are perpendicular to each other; the planes where the two side end surfaces of the fixed steel plate B21 connecting the friction steel plate B22 and the rear arch rib segment 51 are located are perpendicular to each other.

[0055] Preferably, the surfaces of the friction steel plate A123 and the friction steel plate B22 that are in contact with each other are both rough surfaces that increase friction. In the process of the elastic connector transitionally connecting the front arch rib segment 50 and the rear arch rib segment 51, the main load-bearing position is the contact surface of the friction steel plate A123 and the friction steel plate B22. Using the rough surface that increases friction can further enhance the connection strength and stability.

[0056] The elastic connector of the present invention is arranged across both sides of the joint, and temporarily fixes the arch rib segments on both sides before the joint 53 is welded, bears the weight of the arch rib segments on both sides of the joint 53, and allows the lifting equipment to unhook in advance; it reduces the time occupied by the lifting equipment, improves the utilization rate of the lifting equipment, reduces the construction cost, and speeds up the installation efficiency. The elastic connector is used to install the arch rib segments, and the bridge formed can achieve stress-free closure because each arch rib segment is installed to the designed position, and each arch rib segment has no lateral and vertical deviation, so that the bridge is completed without secondary stress inside.

[0057] The present invention also discloses an arch rib assembly method based on the elastic connector. In the actual installation process of multiple arch rib segments, the arch rib segments need to be hoisted and spliced ​​one by one. For example, there are three arch rib segments A, B and C. After the arch rib segment A is hoisted, the arch rib segment B is hoisted; at this time, the arch rib segment A acts as the front arch rib segment 50, and the arch rib segment B acts as the rear arch rib segment 51. When the arch rib segment B is hoisted and the arch rib segment C is hoisted, the arch rib segment B acts as the front arch rib segment 50, and the arch rib segment C acts as the rear arch rib segment 51, and so on.

[0058] like Figure 6 and Figure 7 As shown, the arch rib assembly method of the present invention comprises the following steps:

[0059] S1: An elastic component 1 is respectively installed on the four surfaces of one end of the front arch rib segment 50, and the fixed steel plate A11 of each elastic component 1 is vertically welded to one surface of the front arch rib segment 50; a matching component 2 is respectively installed on the four surfaces of the matching end of the rear arch rib segment 51; the fixed steel plate B21 of each matching component 2 is vertically welded to one surface of the rear arch rib segment 51;

[0060] S2: Use lifting equipment to lift the arch rib segment, and align the friction steel plate B22 of the rear arch rib segment 51 with the friction steel plate A123 fixed to the front arch rib segment 50;

[0061] S3: Install the cable 55 on the rear arch rib segment 51, and tension the cable 55 to the design value, while releasing the hoisting equipment of the rear arch rib segment 51; use a total station to measure whether the cantilever end 54 of the rear arch rib segment 51 is offset relative to the design position; if not, go to S5; if yes, go to S4;

[0062] S4: Increase the adjustment bolt 121 of the elastic connector corresponding to the offset side of the joint 53 or decrease the adjustment bolt 121 of the elastic connector on the opposite side of the offset to adjust the compression amount of the elastic steel plate 122 until the cantilever end 54 reaches the designed position;

[0063] S5: Weld the joint 53 between the front arch rib segment 50 and the rear arch rib segment 51, and cut off the elastic connecting piece.

[0064] Specifically, before step S1 , the fixing steel plate A11 , the adjusting bolt 121 and the elastic matching component 12 are assembled into the elastic component 1 , and the fixing steel plate B21 and the friction steel plate B22 are assembled into the matching component 2 in the factory.

[0065] In step S4, the adjustment of the adjusting bolt 121 at the joint 53 is as follows: the four surfaces matching the front arch rib segment 50 and the rear arch rib segment 51 are the surface where the buckle 55 is located as the upper surface, the surface opposite to this surface is the lower surface, and the other two surfaces are the left and right surfaces. When the cantilever end 54 deviates from the design position, since the rear arch rib segment 51 is in a state of suspension by the buckle 55, it will shake, and it is necessary to continuously adjust the elastic connectors on the four surfaces until the cantilever end 54 reaches the design position. During the adjustment process, when the cantilever end 54 deviates upward relative to the design position, the adjusting bolt 121 of the upper elastic connector is increased (even if the V-shaped spring plate 1221 is extended) or the adjusting bolt 121 of the lower elastic connector is decreased (even if the V-shaped spring plate 1221 is compressed). When the cantilever end 54 deviates to the left, the adjusting bolt 121 of the elastic connector on the left is increased or the adjusting bolt 121 of the elastic connector on the right is decreased.

[0066] Specifically, the friction steel plate A123 is provided with a plurality of connection holes A1222 , and the friction steel plate B22 is provided with a plurality of connection holes B2202 ; the connection holes A1222 and the connection holes B2202 are located in one-to-one correspondence, and are fixed by passing through high-strength bolts 3 .

[0067] Between steps S1 and S2, the following steps are also included: trial assembling and checking the elastic component 1 on the front arch rib segment 50 and the matching component 2 on the rear arch rib segment 51, and then dismantling them to avoid large errors in the matching of the elastic component 1 and the matching component 2, which would affect the assembly of the arch rib segments.

[0068] In step S2, the alignment and fixing of the friction steel plate B22 to the friction steel plate A123 includes the following steps: using a lifting device to move the arch rib segment 51 closer to the front arch rib segment 50; when any connection hole B2202 of the rear arch rib segment 51 is aligned with the corresponding connection hole A1222, it is quickly fixed with a punch; then the two arch rib segments are slowly moved, and the remaining connection holes B2202 and connection holes A1222 are fixed with high-strength bolts 3, and the punches are removed and replaced with high-strength bolts 3.

[0069] In the actual construction process, it is difficult to align the connection hole B2202 and the connection hole A1222 due to the large shaking of the arch rib segment. The present invention adopts the punching nail to assist the transition, which greatly improves the construction efficiency.

[0070] Preferably, two corresponding connection holes are first fixed with punches, and then the other two corresponding connection holes are fixed with high-strength bolts 3 , and then the punches are removed and replaced with high-strength bolts 3 .

[0071] Furthermore, the fixing steel plates A11 of the elastic component 1 and the fixing steel plates B21 of the matching component 2 are both two pieces, and the two fixing steel plates A11 are arranged in parallel with each other, and each fixing steel plate A11 and a fixing steel plate B21 are located in the same plane. In step S1, the two fixing steel plates A11 and the two fixing steel plates B21 are vertically welded to the front arch rib segment 50 and the rear arch rib segment 51 respectively; in step S4, cutting off the elastic connector includes: cutting off the fixing steel plate A11 from the front arch rib segment 50; cutting off the fixing steel plate B21 from the rear arch rib segment 51.

[0072] Preferably, when the elastic connector is cut, it is cut as close to the outer surface of the arch rib segment as possible. After cutting, the elastic connector can be recycled, further reducing the construction cost.

[0073] The arch rib assembly method using elastic connectors of the present invention can assist in the installation of arch rib segments by matching the elastic connectors on four surfaces of the joint 53. Before welding the joint 53, the cantilever end of the rear arch rib stage 51 is adjusted to the designed position to keep it from shaking, thereby reducing the difficulty of installation caused by the shaking of the lifting equipment.

[0074] When the cantilever end of the rear arch rib segment 51 is offset from the designed position, the thickness of the elastic steel plate 122 is changed by adjusting the adjusting bolts 121 of the elastic connectors on the four surfaces, thereby achieving adjustment of errors in multiple directions, thereby accelerating the positioning speed of the rear arch rib segment 51, improving the positioning accuracy, eliminating the arch rib assembly error, ensuring the arch rib assembly line, achieving stress-free closure, and eliminating secondary internal forces after the bridge is completed, making the completed bridge structure safer and more reliable.

[0075] The present invention is not limited to the above-mentioned embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
