Description

Technical Field

[0001] This utility model relates to the field of Bailey beam dismantling and hoisting technology, and more specifically, to a Bailey beam dismantling and hoisting device for ultra-high and long-span structures. Background Technology

[0002] Bailey beams, also known as Bailey panels or Bailey frames, are a type of modular steel truss structure. Their advantages include ease of assembly with manual labor and simple tools, adaptability to emergency engineering needs, reusable standard components reducing costs, and adjustable spans and heights, making them suitable for complex sites. While Bailey beams can be dismantled using cranes, cranes are limited by space constraints; their rotation is restricted in confined spaces, operation is difficult with tall buildings, and there may be issues such as working across high-voltage power lines. Alternatively, Bailey beams can be dismantled using pre-set anchor points and hoisted with winches. However, the anchor points must be designed to allow for the installation of pulley systems to the top of the Bailey beam, and the anchor points must be properly secured after hoisting to avoid interfering with subsequent building operations.

[0003] In the prior art, for example, patent publication number CN207878927U discloses a Bailey bridge lifting frame for the top of a large-diameter silo. The Bailey beam is hoisted by pre-embedding the lifting frame and holes in the top of the building. However, since the holes in the top of the building are pre-embedded parts, rainwater will seep in through the holes later. Moreover, hoisting through the holes may cause wear and cracks in the holes due to contact between the steel ropes, making subsequent waterproofing more prone to failure. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a Bailey beam dismantling and hoisting device for ultra-high, long-span structures. This device uses a pre-reserved hoisting hole on the roof panel with a waterproof sleeve installed, and a protective bracket and rollers to lift the bending point of the steel rope, thereby enhancing the waterproofing effect and reducing wear at the pre-reserved hoisting hole.

[0005] This utility model is achieved through the following technical solution: a Bailey beam dismantling and hoisting device for ultra-high and long-span structures, including a roof panel, a number of reserved hoisting holes on the roof panel, and a waterproof sleeve in each of the reserved hoisting holes, with the waterproof sleeve extending out of the top of the roof panel; It also includes a protective support frame, the height of which is greater than the height of the waterproof sleeve extending out of the top of the roof panel, and the protective support frame is equipped with rollers. It also includes a winch with a steel rope wound around it. The steel rope passes through a pre-reserved hoisting hole after being bent by a roller.

[0006] Furthermore, a decorative cap mounting base is provided at the bottom of the reserved hoisting hole.

[0007] Furthermore, a cap is detachably connected to the top of the waterproof sleeve.

[0008] Furthermore, the cap is fixedly connected to the suspension point of the basket.

[0009] Furthermore, the protective bracket includes a base plate, with support frames fixedly connected to both sides of the base plate, and a crossbeam fixedly connected to the top of the support frame, with rollers located on the crossbeam.

[0010] Furthermore, an alignment groove is provided on the base plate, which engages with the waterproof sleeve.

[0011] Furthermore, an extension support rod is fixedly connected to the bottom of the crossbeam, and an inner lining tube is vertically slidably connected to the side of the extension support rod away from the crossbeam.

[0012] Furthermore, a lifting base is provided at the bottom of the winch.

[0013] The technical solution of this utility model has at least the following beneficial effects: The roof panel is a board that can directly bear the roof load. Located on the roof of the building, pre-drilled hoisting holes are embedded during concrete pouring during construction. Because the roof panel is at the top of the building, it provides a high vantage point for the removal and hoisting of Bailey beams.

[0014] When in use, the protective bracket and winch are installed on the top of the roof panel. After the steel rope is pulled through the roller on the protective bracket, it is inserted into the reserved hoisting hole and passed through the steel rope, so that the steel rope extends downward to the Bailey beam to be removed. After the operator can connect the Bailey beam to the steel rope, the Bailey beam is disassembled. With the cooperation of the steel rope and the winch, the Bailey beam is slowly lowered until it reaches the ground, and then unloaded and loaded onto the vehicle.

[0015] The waterproof sleeve, installed in the pre-drilled mounting hole, replaces the inner surface of the original waterproof sleeve, replacing cement or concrete with waterproof material. This effectively reduces the probability of gaps forming or increased structural porosity due to rainwater erosion. Furthermore, the waterproof sleeve extends upwards beyond the roof panel, raising the water inlet to prevent flooding of the pre-drilled mounting hole and facilitating waterproof joint installation.

[0016] The protective bracket can raise the roller. After the protective bracket raises the roller, the steel rope can bend at the roller. In this way, the bend of the steel rope will not cause wear to the hoisting hole and the waterproof sleeve, effectively ensuring the waterproofing measures and the quality of the building.

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following detailed description illustrates the specific implementation method: Example 1: As attached Figures 1-3The diagram shows a Bailey beam dismantling and hoisting device for an ultra-high, long-span structure. It includes a roof panel 1 with several pre-drilled hoisting holes 2, each containing a waterproof sleeve 3 extending beyond the top of the roof panel 1. The installation process for the waterproof sleeve 3 is the same as that for conventional roof pipe waterproofing. It also includes a protective support 4, the height of which is greater than the height of the waterproof sleeve 3 extending beyond the top of the roof panel 1. The protective support 4 is equipped with rollers 404. Furthermore, it includes a winch 5 with a steel rope 6 wound around it. The steel rope 6 is bent by the rollers 404 and then passes through the pre-drilled hoisting holes 2. There are two protective supports 4 and two winches 5, allowing for Bailey beam hoisting from two points.

[0023] This embodiment is used in ultra-high, long-span structures, which are spanning structures in high-rise buildings. In this example, the specific ultra-high, long-span structure is located between a hotel and a commercial office building, consisting of a roof panel 1 spanning the area between the two buildings. The roof panel 1 is supported on both sides by the hotel and the commercial office building, and after completion, most of the bottom area of ​​the roof panel 1 is suspended in the air. During construction, a frame beam + steel cantilever platform beam + Bailey beam + I-beam is used as the supporting structure for the construction section.

[0024] During construction, pre-drilled hoisting holes 2 are embedded in the concrete pouring. Since the roof panel 1 is at the top of the building, it provides a high point for the removal and hoisting of the Bailey beams. In use, the protective bracket 4 and winch 5 are installed on top of the roof panel 1. The steel cable 6 is pulled through the roller 404 on the protective bracket 4 and inserted into the pre-drilled hoisting hole 2, passing through the steel cable 6 and extending downwards to the Bailey beam to be removed. The operator can then connect the Bailey beam to the steel cable 6, dismantle the Bailey beam, and, with the cooperation of the steel cable 6 and winch 5, slowly lower the Bailey beam until it reaches the ground, where it is unloaded and loaded onto a truck.

[0025] The waterproof sleeve 3, located within the pre-reserved installation hole 2, replaces the inner surface of the waterproof sleeve 3, ensuring that its inner surface is no longer cement or concrete but rather waterproof material. This effectively reduces the probability of cracks forming in the cement or concrete under rainwater erosion or an increase in structural porosity. Furthermore, the waterproof sleeve 3 extends upwards beyond the roof panel 1, raising the water inlet with the allowance to prevent the pre-reserved installation hole 2 from being flooded, while also facilitating waterproof joint work.

[0026] The protective bracket 4 can raise the roller 404. Normally, the roof panel 1 will have multiple reserved hoisting holes 2 for operation on Bailey beams at different locations. Theoretically, the winch 5 can release a steel rope 6 that passes directly vertically through the reserved hoisting hole 2. However, the winch 5 is heavy and not convenient to move frequently. Therefore, the winch 5 can adjust the length of the released steel rope 6 to allow the steel rope 6 to pass through different reserved hoisting holes 2. However, this will cause the steel rope 6 to be bent before entering the reserved hoisting hole 2. In subsequent operations, bending may cause wear to the reserved hoisting hole 2 and the waterproof sleeve 3.

[0027] After the protective bracket 4 raises the roller 404, the steel rope 6 can bend at the roller 404, which reduces the wear of the steel rope 6 on the lifting hole and the waterproof sleeve 3, effectively ensuring the waterproofing measures and the quality of the building.

[0028] Example 2: The difference from the above embodiment is that the bottom of the reserved hoisting hole 2 is provided with a decorative cap mounting seat 7, and the top of the waterproof sleeve 3 is detachably connected with a cap 8, and the hoisting point 9 of the basket is fixed on the cap 8 with bolts.

[0029] The pre-reserved hoisting hole 2 will remain after the Bailey beam is removed, allowing for the installation of a decorative cap via the decorative cap mounting bracket 7 to beautify the bottom of the hole. The waterproof sleeve 3 will also remain, its top sealed with a cap 8 to prevent water ingress. Furthermore, since the waterproof sleeve 3 protrudes from the roof panel 1, a hoisting point 9 can be installed on it for later curtain wall cleaning.

[0030] Example 3: The difference from the above embodiment is that the protective bracket 4 includes a base plate 401, and support frames 402 are welded and fixed on both sides of the base plate 401. A crossbeam 403 is welded and fixed on the top of the support frame 402, and a roller 404 is located on the crossbeam 403.

[0031] A positioning groove 405 is provided on the base plate 401, which engages with the waterproof sleeve 3. An extension support rod 406 is bolted to the bottom of the crossbeam 403, and an inner liner tube 407 is vertically slidably connected to the side of the extension support rod 406 away from the crossbeam 403. A lifting base 10 is provided at the bottom of the winch 5, which is a hydraulic lifting platform.

[0032] The area of ​​the base plate 401 can be set relatively large to distribute the pressure when the roller 404 bears the load, avoiding excessive local pressure on the roof panel 1. The roller 404 needs to be aligned with the waterproof sleeve 3 so that the steel rope 6 can enter the reserved hoisting hole 2 vertically after being bent by the roller 404, thereby reducing wear on the waterproof sleeve 3. Therefore, an alignment groove 405 is provided, which can be engaged with the waterproof sleeve 3 to complete the matching and alignment. However, during hoisting, the Bailey beam and the steel rope 6 may sway due to wind, causing the steel rope 6 to collide with the waterproof sleeve 3 and cause wear on the waterproof sleeve 3. Therefore, an extension support rod 406 is fixedly connected to the bottom of the crossbeam 403. The user can slide the inner lining tube 407 into the waterproof sleeve 3. During hoisting, the inner lining tube 407 can protect the waterproof sleeve 3 to reduce damage to the waterproof sleeve 3 caused by the steel rope 6.

[0033] Since the winch 5 needs to lower the steel cable, its height should preferably be greater than that of the waterproof sleeve 3. However, the top of the roof panel 1 may not be flat, and some parts may be higher than others. To facilitate adjustment, a lifting base 10 is set at the bottom of the winch 5. When the winch 5 is deployed at a low position, the height of the winch 5 can be increased by raising the winch 5, which facilitates operation.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
