Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, in particular to a building vertical hole construction platform and a use method thereof. BACKGROUND

[0002] In the process of building construction, especially in the process of super high-rise building construction, the traditional horizontal and vertical structure synchronous construction technology is gradually eliminated, and the vertical structure priority construction has become a trend. Super high-rise buildings usually adopt tube-in-tube or frame-tube structure. These two structures need to construct the inner tube or core tube first, and then construct the outer tube or outer frame. Multiple vertical holes are often set between the shear walls or structural columns of super high-rise buildings. When the vertical holes need to install mechanical and electrical equipment, air pipes, drainage pipes or perform decoration work, a working platform is often set up by using a landing scaffold or a cantilever steel structure.

[0003] However, when the landing scaffold or the cantilever steel platform is used to construct the vertical hole, the construction platform can only be fixed at a specific position of the vertical hole. When the workers stand on the construction platform to work, the height of the construction platform cannot be flexibly adjusted, which is not convenient for the workers to work. SUMMARY

DETAILED DESCRIPTION

[0048] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0049] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc. indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. It should be understood that the terms "first", "second", etc. are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0050] As Figure 1As shown, the preferred embodiment of the building vertical opening construction platform of the present application comprises a first lifting mechanism 1, a second lifting mechanism 2 and a lifting platform 3 arranged in the vertical opening 6, the inner side of the vertical opening 6 is fixed with a plurality of connecting structures, each connecting structure is arranged in sequence and spaced from top to bottom; the first end of the first lifting mechanism 1 and the first end of the second lifting mechanism 2 are both connected with the lifting platform 3; the second end of the first lifting mechanism 1 and the second end of the second lifting mechanism 2 are respectively detachably connected with the two connecting structures spaced from top to bottom; the first lifting mechanism 1 drives the lifting platform to rise, so that the second end of the second lifting mechanism 2 is switched to the connecting structure above the second end of the first lifting mechanism 1, so that the second lifting mechanism 2 drives the lifting platform 3 to rise; or the first lifting mechanism 1 drives the lifting platform 3 to descend, so that the second end of the second lifting mechanism 2 is switched to the connecting structure below the second end of the first lifting mechanism 1, so that the second lifting mechanism 2 drives the lifting platform 3 to descend. Therefore, the building vertical opening construction platform of the present application can flexibly adjust the height of the construction platform by alternately connecting the first lifting mechanism 1 and the second lifting mechanism 2 to the connecting structure, which is convenient for workers to work. In addition, when using the floor type scaffold, the height of the scaffold body increases continuously as the construction floor increases, the load of the bottom scaffold body also increases, and a large amount of steel is consumed, the construction process is complex and the construction cost is high; when using the cantilever type steel platform, the embedded steel bars are usually used to connect the scaffold to the wall, during the construction process of the shear wall, before pouring concrete in the shear wall, one end of the embedded steel bar is welded with the steel bar frame in the wall according to the design drawing, so as to position each embedded part and connect it to the steel bar frame in the shear wall, after pouring concrete in the shear wall, the other end of the embedded part extends out of the shear wall to connect the scaffold, after the completion of the scaffold construction, in order to avoid the rust of the embedded steel bar leading to the rust of the steel bar frame in the shear wall, the extending end of the embedded steel bar also needs to be treated to prevent rust, the construction process is complex and the construction cost is high; the building vertical opening construction platform of the present application has lower construction cost than the floor type scaffold and the cantilever type steel platform.

[0051] Specifically, as shown in Figure 4 、 Figure 5 、 Figure 11 The first lifting mechanism 1 comprises four first lifting ropes 11 arranged at the four corners of the lifting platform 3, one end of each first lifting rope 11 away from the lifting platform 3 is connected with a first electric hoist 12, and each first electric hoist 12 is detachably connected with each connecting structure;

The second end of the first lifting mechanism 1 and the second end of the second lifting mechanism 2 are equipped with hooks, which are respectively attached to the corresponding binding holes. The steel structural beams 14 are the steel beam nodes around the floor openings of the high-rise building. No additional construction is required. The steel structural beams 14 are used as lifting points, and in conjunction with electric hoists, the lifting platform 3 is raised and lowered. No drilling or pre-embedding is required, and the stability is good.

[0054] Specifically, each steel structure beam 4 has a rope loop 41 tied to its outer side, and each hook is attached to the corresponding rope loop 41, forming a connecting structure. The rope loop 41 is a steel wire rope, which is detachably connected to the steel structure beam 4. After construction is completed, the steel wire rope can be removed from the steel structure beam 4, allowing it to be reused, further reducing the construction cost of the vertical opening construction platform of this invention.

[0055] To ensure the stability of the lifting platform, in this embodiment, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 15 As shown, two guy ropes 5 are symmetrically arranged on both sides of the lifting platform 3. The end of each guy rope 5 away from the lifting platform 3 extends downward at an angle and is tied to the corresponding connecting structure. Specifically, one of the two guy ropes 5 is located on one side of the lifting platform 3, and the other guy rope 5 is located on the other side of the lifting platform 3. The two guy ropes 5 are arranged symmetrically about the center of the lifting platform 3, thereby ensuring the stability of the lifting platform 3.

[0056] In this embodiment, the lifting platform 3 includes a base plate 31 and a protective railing 32 arranged around the periphery of the base plate 31. A kick plate 33 is provided on the bottom periphery of the protective railing 32. The kick plate can prevent materials or debris from falling outside the lifting platform 3, thus ensuring construction safety.

[0057] The guardrail 32 includes vertical bars 321 arranged at intervals around the periphery of the base plate 31. A horizontal bar 322 is connected between each pair of adjacent vertical bars 321. The lower end of each vertical bar 321 can be detachably connected to the edge of the base plate 31.

Figure 9 、 Figure 10 The vertical rod 321 is two parallel and spaced steel pipes, and the lower part of each steel pipe is welded with a first connecting plate 323. Specifically, the first connecting plate 323 is provided with two spaced first mounting holes, and the lower part of each steel pipe is provided in and welded in the first mounting hole. The cross beam 311 is arranged between the two steel pipes, and the lower end of the first connecting plate 323 abuts against the upper end of the cross beam 311. The lower end of each steel pipe is sleeved with a second connecting plate 324. Specifically, the second connecting plate is provided with two spaced second mounting holes, and the two second mounting holes are coaxially arranged with the corresponding first mounting holes. The lower end of each steel pipe is provided in the corresponding second mounting hole. The first connecting plate 323 and the second connecting plate 324 are connected with a first screw 325 and a second screw 326. The lower end of the first screw 325 and the lower end of the second screw 326 are both provided through the second connecting plate 324 and connected with a nut. By screwing the nut, the first connecting plate and the second connecting plate can be moved closer to each other to clamp the cross beam 311, or the first connecting plate and the second connecting plate can be moved away from each other, so that the vertical rod 321 can be removed from the cross beam 311.

[0059] In this embodiment, as shown in Figures 11 to 13 The end of the cross beam 311 is provided with a U-shaped bolt 318, and the threaded end of the U-shaped bolt 318 is provided through the cross beam 311 and connected with a nut 319, so that the U-shaped bolt 318 is detachably connected to the cross beam 311.

Specifically, the U-shaped bolt is arranged at an angle of 80° with the cross beam 311, and the first hoisting rope and the second hoisting rope are both made of an 8-fold safety factor and a 20mm fiber core steel wire rope.

[0062] Step S2, the first position of the vertical hole 6 is constructed; specifically, before construction, the components and their accessories that need to be installed are transported to the floor where they need to be installed by construction elevators or manually and placed next to the lifting platform 3. The construction content includes water pipes or air pipes 7, and the height of the lifting platform 3 can be adjusted by the first lifting mechanism 1 during construction to facilitate worker operation.

[0063] Step S3, the lifting platform 3 is lowered to the first set position by the first lifting mechanism 1; specifically, after the top air pipe 7 or drain pipe and other construction is completed, the lifting platform 3 is lowered to the lower limit position of the first lifting mechanism.

[0064] Step S4, the second end of the second lifting mechanism 2 is connected to the connecting structure below the second end of the first lifting mechanism 1;

[0065] Step S5, the second end of the first lifting mechanism 1 is removed from the connecting structure above the second end of the second lifting mechanism 2, and thereafter, the height of the lifting platform 2 is adjusted step by step downward by the second lifting mechanism 2, thereby facilitating the worker to construct the second position of the vertical hole 6, which is below the first position;

[0066] Step S6, the lifting platform 3 is lowered to the second set position by the second lifting mechanism 2; specifically, after the second position is constructed, the second lifting mechanism 2 falls to the limit position.

[0067] Step S7, the second end of the first lifting mechanism 1 is connected to the connecting structure below the second end of the second lifting mechanism 2;

[0068] Step S8, the second end of the second lifting mechanism 2 is removed from the connecting structure above the second end of the first lifting mechanism 1, and the third position of the vertical hole 6 is constructed, which is below the second position;

[0069] Step S9, steps S3 to S8 are repeated until the lifting platform 3 is lowered to the bottom of the vertical hole 6.

[0070] Among them, steps S1, S4 and S7 all include binding the cable wind rope 5 to the connecting structure below the lifting platform 3;

[0071] Between steps S2 and S3, between steps S5 and S6, and between steps S8 and S9, the cable wind rope 5 is removed from the connecting structure below the lifting platform 3.

[0072] In this embodiment, in step S1, the second end of the first lifting mechanism 1 is connected to the connecting structure at the top of the vertical hole 6, which includes the following steps:

[0074] Step S12, connecting the first end of the first lifting mechanism 1 and the first end of the second lifting mechanism 2 on the lifting platform 3;

[0075] Step S13, alternately connecting the second end of the first lifting mechanism 1 and the second end of the second lifting mechanism 2 on each connecting structure, so as to lift the lifting platform 3 to the top of the vertical hole 6. Specifically, the process of lifting the lifting platform is similar to the operation method of lowering the lifting platform 2.

[0076] In summary, the building vertical hole construction platform of the present application comprises a first lifting mechanism 1, a second lifting mechanism 2 and a lifting platform 3 arranged in the vertical hole 6. The inner side of the vertical hole 6 is fixed with a plurality of connecting structures, and each connecting structure is arranged in sequence and spaced from top to bottom.

The second end of the first lifting mechanism 1 and the second end of the second lifting mechanism 2 are respectively detachably connected to the two connecting structures spaced above and below. The first lifting mechanism 1 drives the lifting platform to rise, so that the second end of the second lifting mechanism 2 is switched to the connecting structure above the second end of the first lifting mechanism 1, so that the second lifting mechanism 2 drives the lifting platform 3 to rise. Or the first lifting mechanism 1 drives the lifting platform 3 to descend, so that the second end of the second lifting mechanism 2 is switched to the connecting structure below the second end of the first lifting mechanism 1, so that the second lifting mechanism 2 drives the lifting platform 3 to descend. Therefore, the building vertical hole construction platform of the present application can flexibly adjust the height of the construction platform by alternately connecting the first lifting mechanism 1 and the second lifting mechanism 2 on the connecting structure, which is convenient for workers to work. Moreover, the building vertical hole construction platform of the present application has lower construction cost compared with the floor type scaffold and cantilever type steel platform.
