Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a prefabricated assembly frame for bridge main towers. Background Technology

[0002] During the vertical rotation of the main tower of the bridge, it is necessary to weld and assemble a support frame for the main tower on the bridge steel box girder or bridge deck. Multiple support frames arranged side by side provide oblique support for the main tower in the horizontal direction.

[0003] However, during welding and assembly, the entire jig is often assembled into a fixed size, making it inconvenient to adjust it according to actual construction needs. Furthermore, it is not applicable to bridge main towers of various specifications during construction, exhibiting poor adaptability to main towers with different requirements, thus affecting the support effect on the main tower. It cannot be reused, causing waste and losses for construction units, and directly impacting project schedule, production costs, and economic benefits.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a prefabricated assembly frame for bridge main towers.

[0007] The first telescopic adjustment component is disposed between two side-by-side fixed frames and is used to adjust the distance between the two fixed frames;

[0008] A first connecting component is disposed between the fixed frame and the adjusting frame, for connecting the adjusting frame to the top of the fixed frame;

[0009] The inclined support assembly includes a fixed plate disposed on the top of the adjusting frame and a support plate rotatably disposed on one side of the fixed plate and in contact with the main tower support of the bridge.

[0010] Furthermore, the first telescopic adjustment assembly includes a first support rod and a second support rod that are rotatably connected in a cross manner.

[0011] Furthermore, vertical grooves are provided on the exterior of the four columns of the fixed frame, and the screw rod and the guide rod are respectively connected to two of the vertical grooves arranged side by side along the length direction of the fixed frame.

[0012] Furthermore, the lower end of the adjustment frame is provided with a height-adjustable adjustment unit;

[0013] The adjustment unit includes a hydraulic cylinder correspondingly disposed at the bottom end of the adjustment frame, and the movable end of the hydraulic cylinder is provided with connecting rods that are sequentially connected end to end.

[0014] Furthermore, the first connecting assembly includes an upper connecting ring and a lower connecting seat respectively disposed at the top of the fixed frame and the bottom of the hydraulic cylinder for connection. The upper connecting ring has two L-shaped arc grooves symmetrically arranged against the inner ring surface, and the lower connecting seat is provided with a damping crossbar for rotational limitation with the L-shaped arc grooves.

[0015] Furthermore, both the fixing plate and the support plate are slotted and cut in the middle and adjusted by telescopic sliding with guide rods.

[0035] like Figure 1-8As shown, the present invention relates to a prefabricated assembly frame for bridge main towers, comprising multiple frame units for obliquely supporting the bridge main towers. Each frame unit includes at least two fixed frame bodies 100 arranged side by side, and one or more adjustable frame bodies 200 are vertically stacked on each fixed frame body 100. The invention also includes:

[0036] The first telescopic adjustment component 1 is disposed between two side-by-side fixed frames 100 and is used to adjust the distance between the two fixed frames 100.

[0037] The first connecting component 2 is disposed between the fixed frame 100 and the adjusting frame 200, and is used to connect the adjusting frame 200 to the top of the fixed frame 100;

[0038] The inclined support assembly 3 includes a fixed plate 31 disposed on the top of the adjusting frame 200 and a support plate 32 rotatably disposed on one side of the fixed plate 31 and in contact with the main tower support of the bridge.

[0039] In practice, multiple frame units are arranged along the length of the bridge deck to support the main tower of the bridge. Two or more fixed frames 100 are selected along the longitudinal width of the main tower of the bridge for bottom support. Based on the ground height of multiple points on the main tower of the bridge with diagonal support, one or more adjustable frames 200 are vertically stacked on the corresponding fixed frames 100 through the first connecting component 2. Then, the tilt angle of the support plate 32 is adjusted on the fixed plate 31 included in the diagonal support component 3, so that the diagonal support of the main tower of the bridge is more stable. This makes the disassembly and assembly of this prefabricated assembly frame convenient and meets the current actual construction needs.

[0040] In one embodiment, the first telescopic adjustment assembly 1 includes a first support rod 11 and a second support rod 12 that are rotatably connected. Both ends of the first support rod 11 and the second support rod 12 are detachably provided with movable blocks 13. A lead screw 14 is movably provided on the two movable blocks 13 arranged vertically on one side, and a guide rod 15 is movably provided on the two movable blocks 13 arranged vertically on the other side. This design, using a pivot shaft for connection at the center of the first support rod 11 and the second support rod 12, and with bolts at both ends of the first support rod 11 and the second support rod 12 to detach the corresponding movable blocks 13, allows the two movable blocks 13 to move towards or away from each other under the rotation of the lead screw 14 on one side and the limiting position of the guide rod 15 on the other side. This increases or decreases the included angle between the first support rod 11 and the second support rod 12 combined on the two movable blocks 13, achieving adjustable spacing between the two side-by-side fixed frames 100. If the maximum spacing between the two side-by-side fixed frames 100 is insufficient to meet the actual support requirements, the corresponding first support rod 11 and second support rod 12 can be installed on one of the fixed frames 100 to increase its length, making it universally applicable.

[0041] It should be noted that the lead screw 14 has two sections with opposite thread directions.

[0042] It should be noted that there are two of each of the first support rod 11 and the second support rod 12, and they are symmetrically installed on both sides of the two parallel fixed frames 100 along the length of the bridge deck.

[0043] In one embodiment, vertical grooves 101 are provided on the exterior of the four columns of the fixed frame 100. The screw 14 and guide rod 15 are respectively connected to two of the vertical grooves 101 arranged side-by-side along the length of the fixed frame 100. This design, by machining the vertical grooves 101 on the exterior of the four columns of the fixed frame 100 and installing the screw 14 and guide rod 15 in the two vertical grooves 101 arranged side-by-side along the length of the fixed frame 100, achieves an adjustable connection between the two side-by-side fixed frames 100, allowing the first telescopic adjustment assembly 1 to be positioned at an adjustable distance.

[0044] In one embodiment, the lower end of the adjustment frame 200 is provided with a height-adjustable adjustment unit 5;

[0045] The adjustment unit 5 includes a hydraulic cylinder 51 correspondingly disposed at the bottom end of the adjustment frame 200. A connecting rod 52, sequentially connected end-to-end, is provided on the movable side of the hydraulic cylinder 51. This design allows the adjustment frame 200 to be moved upwards for fine-tuning of its height by synchronously activating the hydraulic cylinder 51, which is bolted to the lower end of the adjustment frame 200. This compensates for the height difference between the prefabricated frame units arranged along the length of the bridge deck, ensuring the stability of the fit between the top of the prefabricated frame and the inclined support of the bridge's main tower, thus improving the support effect.

[0046] In one embodiment, the first connecting component 2 includes an upper connecting ring 21 and a lower connecting seat 22 respectively disposed at the top of the fixed frame 100 and the bottom of the hydraulic cylinder 51 for connection. The upper connecting ring 21 has two L-shaped arc grooves 211 symmetrically disposed on the inner ring surface, and the lower connecting seat 22 is provided with a damping crossbar 221 for rotational limitation with the L-shaped arc grooves 211. This design allows for quick assembly and disassembly of the fixed frame 100 and the adjusting frame 200 via a detachable upper connecting ring 21 bolted to the top of the fixed frame 100 and a lower connecting seat 22 rotatably mounted at the bottom of the hydraulic cylinder 51. It utilizes two symmetrical L-shaped arc grooves 211 machined on the inner ring surface of the upper connecting ring 21 and a damping crossbar 221 welded laterally to the inner groove of the lower connecting seat 22. After the damping crossbar 221 is inserted into the upper opening of the two L-shaped arc grooves 211, the lower connecting seat 22 is rotated, placing the damping crossbar 221 at the inner groove opening of the L-shaped arc groove 211. This simplifies the operation.

[0047] In one embodiment, both the fixing plate 31 and the support plate 32 are cut in the middle and adjusted by sliding with a guide rod. An inclined support plate 33 is rotatably mounted on each of the opposite end faces of the fixing plate 31. A slider 34 is movably mounted on the inclined support plate 33, and a positioning block 35 is rotatably mounted on the slider 34. Several evenly distributed positioning grooves 36, adapted to the positioning blocks 35, are provided on each of the opposite end faces of the support plate 32. This design, by cutting the fixing plate 31 and the support plate 32 in the middle and adjusting by sliding with a guide rod, allows for adaptive adjustment of the fixing and support widths of the fixing plate 31 and the support plate 32 according to the distance between the two side-by-side fixed frames 100, ensuring a stable connection between the contact surface of the inclined support of the bridge main tower and the support plate 32.

[0048] Furthermore, by using an inclined support plate 33 rotatably mounted on the opposite end face of the fixed plate 31, and a slider 34 movably mounted on the inclined support plate 33 with a transverse slot, and a positioning block 35 rotatably mounted on the slider 34, the inclined support plate 33 can be rotated and raised to a certain angle. The slider 34 can be moved so that the positioning block 35 rotatably mounted on the slider 34 can be inserted and combined with a positioning groove 36 machined on the corresponding end face of the support plate 32. This achieves the limitation and fixation of the support angle between the fixed plate 31 and the support plate 32 by the inclined support plate 33. The inclination of the support can be adjusted according to the construction requirements, so that the inclined support of the subsequent bridge main tower has a fitting support slope, which improves the stability of the inclined support.

[0049] In one embodiment, a second telescopic adjustment component 4 with adjustable spacing is provided between two side-by-side adjustment frames 200;

[0050] The second telescopic adjustment component 4 has the same structure as the first telescopic adjustment component 1. With this design, by installing the second telescopic adjustment component 4 between the adjustment frames 200 that are correspondingly stacked on the two fixed frames 100, and since the structure of the second telescopic adjustment component 4 is the same as that of the first telescopic adjustment component 1, the spacing between the two side-by-side adjustment frames 200 can also be determined by following the spacing between the two fixed frames 100.

[0051] In one embodiment, a second connecting component 6 for vertical assembly is provided at the top of the adjusting frame 200 and on the end face of the fixing plate 31;

[0052] The second connecting component 6 has the same structure as the first connecting component 2. With this design, by installing the second connecting component 6 on the top of the adjusting frame 200 and connecting it to the fixing plate 31, and with the second connecting component 6 having the same structure as the first connecting component 2, the inclined support component 3 on the top of the adjusting frame 200 can be quickly assembled using the assembly method of the first connecting component 2. The whole assembly is easy to install and disassemble, can be recycled, and does not require repeated welding and cutting.

[0053] It should be noted that the vertical assembly between more than one adjustment frame 200 also adopts the assembly method of the first connecting component 2 described above for quick disassembly and assembly.

[0054] In one embodiment, a fixing seat 102 is provided at the bottom corner of the fixing frame 100. This design, by welding the fixing seat 102 at the bottom corner of the fixing frame 100, can stably fix the fixing frame 100 to the bridge deck, thereby achieving oblique support for the main tower of the bridge.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
