Description

Technical Field

[0001] The utility model relates to a hanging basket for bridge wet joint construction, in particular to a hanging basket for bridge wet joint construction with a fixed structure. Background Art

[0002] Wet joints are important connection parts in concrete box girder bridge structures. Their connection methods directly affect the structural stability and bearing capacity of the entire bridge. In actual projects, common wet joint connection methods include rigid connection, hinged connection and failure state. The hanging basket is anchored and suspended on the constructed beam section to provide an aerial platform for the construction of the next section. After completing the construction of one section, the hanging basket can be moved forward and fixed to carry out the construction of the next section. This cycle continues until the cantilever pouring is completed.

[0003] In wet joint construction, construction workers need to lay wet joint low formwork between the two beams. The upper and lower ends of the side formwork are reinforced with tie bolts or welded steel bars. The joint formwork must be reinforced and the joints must be blocked. A layer of double-sided tape can be affixed to the contour around the original cast-in-place concrete to ensure that the formwork is closely attached to the contour of the original cast-in-place concrete after installation to prevent leakage during concrete pouring. Construction workers usually need to use a hanging basket to go down from the joint to the construction position to carry out the construction of the next section. This cycle continues until the cantilever pouring is completed. Usually, the hanging basket uses a hanging rope to fix the hanging basket on the protruding steel bars of the beam, which is troublesome to fix and inconvenient to disassemble, affecting construction efficiency.

[0004] Therefore, it is necessary to design a hanging basket for bridge wet joint construction with a fixed structure. Utility Model Content

[0005] In order to overcome the shortcomings of troublesome fixing of the suspension rope and affecting the construction efficiency, the technical problem to be solved is: to provide a hanging basket for bridge wet joint construction with a fixed structure.

[0006] The technical solution of the utility model is: a hanging basket for bridge wet joint construction with a fixed structure, including a base plate, vertical rods, fixed blocks, cross rods, guardrails, steel ropes and hooks, the upper rear side of the base plate is symmetrically rotatably connected with the vertical rods, the upper sides of the two vertical rods are connected with fixed blocks on their respective sides away from each other, four cross rods are evenly welded in a linear array between the two vertical rods, the upper front side of the base plate is rotatably connected with the guardrail, the upper part of the guardrail is symmetrically provided with steel ropes, and the end of the steel rope away from the guardrail is fixedly connected with a hook.

[0007] In one embodiment, the fixing block is retractable to increase the force bearing area.

[0008] In one of the embodiments, it also includes an extension plate, a sliding bar, a sliding frame, a guide seat, a first folding rod and a second folding rod. The bottom plate is symmetrically fixed with sliding bars at the front and back, and the bottom plate is symmetrically slidably connected with the extension plate. The extension plates slide on the sliding bars on both sides. The upper and mutually distant sides of the two extension plates are symmetrically rotatably connected with the sliding frames. The two sides of the front of the guardrail and the rear side of the two vertical bars are symmetrically fixed with guide seats. All the sliding frames slide on the corresponding guide seats. The sliding frames located on the front side of the bottom plate are symmetrically rotatably connected with multiple first folding rods at the distant sides. The sliding frames located on the rear side of the bottom plate are symmetrically rotatably connected with multiple second folding rods at the distant sides. The corresponding first folding rods and second folding rods at the front and back are rotatably connected.

[0009] In one of the embodiments, an expansion basket is also included, and the expansion basket is clamped on the top of the guardrail.

[0010] In one embodiment, it also includes a fixing plate and a rotating rod, the upper parts of the vertical rods are symmetrically slidably connected to the fixing plates, and the rotating rods are threadedly connected between the fixing plates.

[0011] In one embodiment, the base plate and the guardrail are both made of lightweight aluminum alloy.

[0012] The beneficial effects are as follows: 1. The utility model fixes the product between two beams by pulling out two symmetrical fixing blocks, and then fixes two hooks on the protruding steel bars of the beams, so that the product can be fixed more conveniently and quickly, thereby better improving the construction efficiency.

[0013] 2. The utility model pushes the sliding frames on the left and right sides open, drives the extension plate to slide on the slide bar, and the sliding frame slides on the guide seat, thereby increasing the operating space for construction workers.

[0014] 3. The utility model allows construction workers to put tools in the expansion basket by clamping the expansion basket on the guardrail. They do not need to bend down to pick up tools when they need to use them. This is more convenient and quicker, and can also prevent tools from rolling and hitting people. The rotating rod can also be turned clockwise to push the fixing plates on both sides outward so that the left and right fixing plates contact and jam with the beam body, making the product more stable when in use and reducing shaking during construction.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] Embodiment: Figure 1-Figure 4 As shown, it includes a base plate 1, a vertical rod 2, a fixed block 3, a cross rod 4, a guardrail 5, a steel rope 6 and a hook 7. The rear side of the top surface of the base plate 1 is symmetrically connected to the vertical rod 2 for rotation. The upper sides of the two vertical rods 2 that are away from each other are fixed with fixed blocks 3 with screws. Four cross rods 4 are welded in a linear array between the two vertical rods 2. The front side of the top surface of the base plate 1 is rotatably connected to the guardrail 5. The top of the guardrail 5 is symmetrically wound with steel ropes 6. The end of the steel rope 6 away from the guardrail 5 is welded with a hook 7. The fixed block 3 is retractable to increase the force-bearing area.

[0022] When in use, push the bottom plate 1 and the guardrail 5 of this product to the side close to the vertical rod 2. When the bottom plate 1 and the guardrail 5 are close to the vertical rod 2, the product is folded, and then the product is placed on its side and lowered through the joint of the two beams. Subsequently, the two fixing blocks 3 are pulled out to increase the gripping area, so that the product can more firmly grasp the two beams of the wet joint, and the two fixing blocks 3 are clamped on the beams on both sides for fixing. After being lowered, the bottom plate 1 is knocked down due to the influence of gravity, and then by fixing the two hooks 7 on the protruding steel bars of the beam, the steel rope 6 pulls the guardrail 5 to open and fix the product more stably. The four horizontal bars 4 fixedly connected between the two vertical rods 2 form a ladder, and the construction workers can go down from the joint of the two beams and go down to the construction position through the four horizontal bars 4.

[0023] like Figure 1 and Figure 3As shown, it also includes an extension plate 8, a slide bar 801, a sliding frame 9, a guide seat 10, a first folding rod 11 and a second folding rod 12. The slide bars 801 are welded symmetrically on the front and rear sides of the base plate 1. The bottom of the base plate 1 is symmetrically and slidably connected with the extension plates 8. The two extension plates 8 slide left and right on the slide bars 801 on the front and rear sides. The two extension plates 8 are symmetrically and rotatably connected to the sliding frames 9 on the sides away from each other. The left and right sides of the front of the guardrail 5 and the side of the rear of the two vertical bars 2 away from each other are symmetrically and fixedly connected with the guide seats 10 up and down. All the sliding frames 9 slide left and right on the corresponding guide seats 10. The sides of the two sliding frames 9 located on the front side of the base plate 1 away from each other are symmetrically and rotatably connected with three first folding rods 11. The sides of the two sliding frames 9 located on the rear side of the base plate 1 away from each other are symmetrically and rotatably connected with three second folding rods 12, and the first folding rods 11 and the second folding rods 12 corresponding to the front and rear are rotatably connected.

[0024] like Figure 1 As shown, an expansion basket 13 is also included, and the expansion basket 13 is clamped on the top of the guardrail 5.

[0025] like Figure 1 and Figure 4 As shown, it also includes a fixing plate 14 and a rotating rod 15. The upper parts of the two vertical rods 2 are symmetrically slidably connected with the fixing plates 14, and the rotating rod 15 is threadedly connected between the two fixing plates 14.

[0026] After the construction personnel go down to the construction site, they press down all the first folding rods 11 and the second folding rods 12 on the left and right sides. The first folding rods 11 and the second folding rods 12 push against each other, making the product more stable during construction and providing fixed support. During the construction process, shaking is likely to occur. The rotating rod 15 can be turned clockwise to push the fixing plates 14 on both sides away from each other, so that the fixing plates 14 contact and get stuck with the beam body, making the product more stable during use and reducing shaking during construction. The structural setting of the fixing plates 14 is limited by the vertical rod 2 and will only slide left and right along the vertical rod 2. When the guardrail 5 rotates, the fixed plate 14 will not rotate. The construction personnel can push the sliding frames 9 on the left and right sides to the side away from each other, and the sliding frames 9 drive the corresponding extension plates 8 to slide to the side away from each other. The two extension plates 8 slide to the side away from each other on the slide bar 801. After opening, the construction personnel's operating space can be increased. The extension basket 13 can also be stuck on the guardrail 5. The construction personnel can put the tools they need to use in the extension basket 13. When the tools are needed, they do not need to bend down to pick them up, which is more convenient and quick. Placing the tools in the extension basket 13 can also prevent the tools from rolling and falling.

[0027] After finishing the construction, the construction personnel pull the sliding frames 9 on the left and right sides toward the side close to the bottom plate 1, and the sliding frames 9 drive the corresponding extension plates 8 to reset toward the side close to the bottom plate 1. After the extension plates 8 and the sliding frames 9 are reset, all the first folding rods 11 and the second folding rods 12 on the left and right sides are pushed upward. After completing the above operations, the construction personnel climb up through the cross bar 4, and then turn the rotating rod 15 counterclockwise to rotate the fixing plates 14 on both sides inward to reset, so that the product is no longer fixed between the two beams, and is unfastened and fixed on the protruding steel bars of the beam. The two hooks 7 are pulled, and since all the first folding rods 11 and the second folding rods 12 are no longer against each other, the steel rope 6 drives the guardrail 5 and the bottom plate 1 to fold toward the side close to the vertical rod 2, so that the bottom plate 1 and the guardrail 5 are close to the vertical rod 2, and the product is folded, and then the grown steel rope 6 is wound around the vertical rod 2, and then the product is rotated 90 degrees and the vertical rod 2 is pulled upward to pull the product out from between the two beams. All materials of this product are made of lightweight aluminum alloy materials, with light weight, and can be operated and turned by one person, thereby improving work efficiency.
