Description

Technical Field

[0001] This application relates to the technical field of hoisting construction, and particularly relates to a hoisting and transportation method for a completed basement. Background Art

[0002] In the related art, there are situations where large equipment needs to be hoisted and transported to the basement. For example, a chiller is hoisted and transported to the target floor in the basement. Specifically, most of the air-conditioning main engine rooms in public buildings are located in the basement, and the chiller needs to be installed in the air-conditioning main engine room. Among them, the weight of the chiller is about 10 tons at the lightest and can reach 20 tons at the heaviest. Therefore, most chillers are hoisted and transported to the basement through the reserved hoisting openings, and after the installation of the chiller and related equipment is completed, the reserved hoisting openings are closed.

[0003] However, for a completed multi-floor basement, there is a situation where the reserved hoisting openings on the floor slabs of at least some floors are misaligned with each other, resulting in that traditional hoisting equipment such as cranes (truck cranes, crawler cranes, and tire cranes) cannot cover all the hoisting openings, that is, large equipment cannot be directly hoisted and transported to the target floor in the basement, which brings difficulties to the transportation process of large equipment. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application proposes a hoisting and transportation method for a completed basement, which can cope with the situation where the reserved hoisting openings on the floor slabs of each floor of the completed basement are misaligned with each other when hoisting and transporting large equipment into the completed basement.

[0043] Refer to Figures 1 to 9 According to the hoisting and transportation method for a completed basement according to an embodiment of the present application, the floor slab of the floor where the hoisting opening a is misaligned relative to the floor slab of the upper floor is the transition floor slab 100 for transporting the target equipment b. The target equipment b is hoisted and transported to the uppermost transition floor slab 100 by a crane. Among them, the following steps are further included:

[0044] S1. Before or after the crane hoists the target equipment b, a temporary hoisting structure 200 is set on the upper floor slab of the current transition floor slab 100 directly above the hoisting opening a on the current transition floor slab 100, and a temporary support platform 300 for temporarily bearing the target equipment b is set on the lower floor slab of the current transition floor slab 100 corresponding to the hoisting opening a on the current transition floor slab 100;

[0046] S3. Remove the temporary support platform 300, and use the temporary hoisting structure 200 to hoist and transport the target equipment b to the lower floor slab of the current transition floor slab 100.

[0047] When hoisting and transporting large equipment into a completed basement, by adopting the hoisting and transportation method for a completed basement according to an embodiment of the present application, it is possible to cope with the situation where the hoisting openings a reserved on the floor slabs of each floor of the completed basement are misaligned with each other.

[0048] It should be noted that after the target equipment b arrives at the site, it is necessary to first inspect the arrived target equipment b.

[0049] In some of these embodiments, the hoisting and transportation method for a completed basement according to the embodiments of the present application further includes the following steps:

[0050] If the lower floor slab of the current transition floor slab 100 in step S3 is the target floor slab, after hoisting and transporting the target device b to the lower floor slab of the current transition floor slab 100 by using the temporary hoisting structure 200, horizontally transport the target device b to the equipment foundation preset on the target floor slab for installing the target device b;

[0051] If the lower floor slab of the current transition floor slab 100 in step S3 is still the transition floor slab 100, after hoisting and transporting the target device b to the lower floor slab of the current transition floor slab 100 by using the temporary hoisting structure 200, continue to transfer the target device b according to the methods of steps S1 to S3 until the target device b is transported to the target floor slab, and then horizontally transport the target device b to the equipment foundation preset on the target floor slab for installing the target device b.

[0052] Refer to Figures 2 to 7 , in some of these embodiments, before hoisting and transporting the target device b to any transition floor slab 100, a detachable temporary support structure 400 is provided below the transition floor slab 100 that will temporarily bear the target device b. By supporting the transition floor slab 100 through the temporary support structure 400, it is beneficial to prevent the transition floor slab 100 that temporarily bears the target device b from being damaged due to the excessive weight of the target device b, thereby being beneficial to ensuring the safety during the construction process. Among them, the temporary support structure 400 is detachably arranged below the transition floor slab 100. After the transfer of the target device b is completed, the temporary support structure 400 can be disassembled, so that it will not occupy the space of the basement and the function of the basement will not be affected.

[0053] Refer to Figures 2 to 7 , in some of these embodiments, the temporary support structure 400 includes a first top support member 410 and a first support 420 arranged at the bottom of the first top support member 410. The first top support member 410 is used to support the transition floor slab 100, and the first support 420 is used to support the first top support member 410. Its structure is simple and easy to implement.

[0054] Specifically, the first top support member 410 is a support plate, so that there is a large contact area between the first top support member 410 and the supported transition floor slab 100, which is beneficial to preventing the transition floor slab 100 from being damaged due to concentrated force in a local area.

[0055] Specifically, the first support 420 is a scaffold, and its technology is mature, which is beneficial to improving the construction efficiency.

[0056] Refer to Figures 2 to 7 , in some of the embodiments, the target device b is horizontally transported by the ground tank c (also known as the handling wheel, the handling trolley or the heavy load transporter), which is beneficial to improving the transportation efficiency.

[0057] Specifically, a plurality of ground tanks c distributed in a rectangular array are arranged below the target device b to disperse the pressure transmitted by the ground tanks c to the transition floor bottom plate 100, which is beneficial to preventing the transition floor bottom plate 100 from being damaged due to concentrated stress in a local area.

[0058] It should be noted that, in some other embodiments, the target device b can also be horizontally transported by the rolling bar.

[0059] In some of the embodiments, when horizontally transporting the target device b, the electric hoist d is used to assist in transporting the target device b, which is beneficial to improving the transportation efficiency.

[0060] Specifically, the electric hoist d is used to pull the target device b in front of the target device b to move horizontally along the horizontal direction.

[0061] In addition, a manual hoist tail is arranged behind the target device b, that is, the manual hoist is used to pull the target device b behind the target device b to prevent the target device b from deflecting during the moving process.

[0062] It should be noted that, in some other embodiments, when horizontally transporting the target device b, the target device b can also be pushed horizontally by manpower or by a hydraulic jacking system.

[0063] Refer to Figures 2 to 4 and Figure 8 , in some of the embodiments, the temporary support platform 300 includes a second top support member 310 and a second bracket arranged at the bottom of the second top support member 310. The second top support member 310 is used to carry the target device b, and the second bracket is used to support the second top support member 310. Its structure is simple and easy to implement.

[0064] Refer to Figure 8 , in some of the embodiments, the second top support member 310 is a channel steel, and the second top support member 310 extends along the horizontal transportation direction of the target device b, so that the second top support member 310 can be used as a guide rail for the ground tank c when horizontally transporting the target device b, thereby being able to limit the moving track of the ground tank c, and further being able to limit the moving track of the target device b to prevent the target device b from deflecting during the moving process.

[0065] Refer to Figures 2 to 4 and Figure 8In some embodiments, the second bracket includes a plurality of vertical support members 320 and a plurality of intermediate connectors 330. The vertical support members 320 are used to support the second top supporting member 310. The intermediate connectors 330 are detachably connected to the vertical support members 320. The intermediate connectors 330 are used to connect and fix the plurality of vertical support members 320. The structure is simple and easy to implement. The intermediate connectors 330 are detachably connected to the vertical support members 320. Therefore, the spacing between the guide rails can be adjusted by replacing the intermediate connectors 330 of different sizes, so as to adapt to target devices b of different sizes. In particular, when multiple target devices b of different sizes need to be hoisted and transported on site, it is beneficial to improve the construction efficiency.

[0066] Specifically, the vertical support member 320 is fixedly connected to the bottom of the second top supporting member 310 , a connecting portion 321 is provided on the side of the vertical support member 320 , and the intermediate connecting member 330 is connected to the connecting portion 321 by bolts.

[0067] When it is necessary to hoist and transport target equipment b of different sizes, a hoisting point is set on the second top supporting member 310 or the vertical supporting member 320, and the temporary supporting platform 300 is hoisted by the corresponding temporary hoisting structure 200, and then the intermediate connecting members 330 of different sizes are replaced to assemble the temporary supporting platform 300 of the required size. In the process of replacing the intermediate connecting members 330 of different sizes, the temporary supporting platform 300 is hoisted by the corresponding temporary hoisting structure 200, which is convenient for adjusting the spacing between the vertical supporting members 320, which is conducive to improving the construction efficiency.

[0068] Reference Figures 2 to 9 In some embodiments, the temporary hoisting structure 200 uses an electric hoist d, wherein the temporary hoisting structure 200 includes a flexible connector 210, a first support 220 and a second support 230, a plurality of through holes e are opened on the floor of the previous floor of the current transition floor 100, two first supports 220 close to each other are placed on the floor of the previous floor of the current transition floor 100 corresponding to the through holes e, a second support 230 is placed on the two first supports 220, and the flexible connector 210 is inserted into the through hole e, wherein one end of the flexible connector 210 passes through the gap between the corresponding two first supports 220 and is connected to the corresponding second support 230, and the other end of the flexible connector 210 is hung with an electric hoist d, and the above structure is easy to implement and easy to dismantle. Among them, the plurality of through holes e can cooperate with the plurality of flexible connectors 210 to hang a plurality of electric hoists d, so that the target equipment b can be lifted at multiple lifting points, which is conducive to improving the stability during the lifting and transportation process.

[0069] Specifically, the flexible connecting member 210 is made of a steel wire rope, the first support member 220 is made of an I-beam, and the second support member 230 is made of a steel round bar.
