Description

Technical Field

[0002] Most road and bridge construction in my country begins with prefabricating concrete beams in blocks, which are then erected. Currently, after beam erection, bridge construction requires wet jointing, which involves pouring concrete between the beam joints to connect the beams horizontally and consolidate them into a single unit. With the development of modern bridge construction technology, bridge heights are gradually increasing. Since bridges often span valleys and rivers, it is often inconvenient to erect supports at the bottom. Therefore, wet jointing is an overhead operation, and the technical advantages of wet jointing for assembled bridges are becoming increasingly important. Making wet jointing safer, more convenient, and more efficient has become a crucial aspect of bridge construction.

[0003] At present, when constructing wet joints, it is often necessary to use a foldable inner hanging basket to facilitate the operation of personnel. Some foldable inner hanging baskets have also been reported in public literature, such as:

[0024] In order to describe the present technology more clearly, the present technology is further described in detail below with reference to the accompanying drawings and embodiments. Example

[0025] A foldable inner hanging basket for bridge wet joint construction, comprising a lifting rod 5, a hanging rod 10 and a hanging basket bottom plate 13, wherein the top of the hanging rod 10 is fixedly provided with a horizontal hanging rod 12 for hanging on the top surfaces of both sides of the bridge wet joint, and both sides of the hanging rod 10 are respectively fixedly provided with a foot pedal 8 for climbing, the lifting rod 5 is vertically connected to the lower end of the hanging rod 10, and both sides of the lifting rod 5 are respectively fixedly connected to a rear upright rod 1 extending downward through a horizontal connecting rod 4, and the two rear upright rods are respectively fixedly connected to the rear upright rod 1 extending downward through a horizontal connecting rod 4. A limit rod 14 extending forward is fixedly connected between the bottom ends of the rods 1, the hanging basket bottom plate 13 is horizontally placed on the upper part of the limit rod 14, and the rear ends of the hanging basket bottom plate 13 are hinged to the inner sides of the two rear upright rods 1 respectively, and the front ends of the hanging basket bottom plate 13 are vertically hinged to a front upright rod 15 respectively. A connecting rod 3 is fixedly connected between the two front upright rods 15, and side rods 2 are hinged between the front upright rods 15 and the rear upright rods 1 on both sides of the hanging basket bottom plate 13.

[0026] A connecting rod 3 is also fixedly connected between the two rear uprights 1 .

[0027] The lifting rod 5 and the hanging rod 10 are detachably connected via a connecting bolt 7 , and the hanging rod 10 is provided with a plurality of adjusting connection holes 9 for adjusting the connection length between the lifting rod 5 and the hanging rod 10 .

[0028] Both ends of the horizontal hanging rod 12 are respectively fixedly connected with a longitudinal sleeve 11 in the longitudinal direction.

[0029] The horizontal hanging rod 12 adopts a structure of two horizontal hanging rods arranged in parallel, and the top end of the hanging rod 10 is fixedly connected to the middle part between the two horizontal hanging rods.

[0030] The top surface of the hanging rod 10 is also connected to the top surfaces of the two horizontal hanging rods through a stiffening plate 16.

[0031] The front upright pole 15 is connected to a hanging rope 6 for lifting the front upright pole 15 .

[0032] The working principle of the foldable inner hanging basket for bridge wet joint construction is as follows: according to the hanging height, select the appropriate position of the adjustment connection hole 9 to install the connecting bolt 7 to fix the lifting rod 5 and the hanging rod 10, and pull the front vertical rod 15 upward by pulling the hanging rope 6, so that the side rod 2 and the hanging basket bottom plate 13 are flipped and folded upward, and then the hanging basket is lowered from the wet joint of the bridge, and the horizontal hanging rod 12 is hooked on the top surfaces on both sides of the wet joint of the bridge. Due to the potential energy of gravity, when the hanging rope 6 is not pulled upward, the side rod 2 and the hanging basket bottom plate 13 will automatically flip downward. Under the limiting action of the limit rod 14, the hanging basket bottom plate 13 flips down and is in a horizontal state. Then the upper end of the hanging rope 6 is buckled with the connecting steel bar of the bridge wet joint. In order to improve safety, steel pipes or wooden sticks are respectively inserted into the longitudinal sleeves 11 on both sides of the horizontal hanging rod 12 to increase the contact area with the top surface of the bridge wet joint. After the operator ties the safety rope, he can climb to the hanging basket bottom plate 13 through the foot pedal 8 of the hanging rod 10 and step on the hanging basket bottom plate 13 to work.
