Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly to a lifting construction method for a suspension structure. Background Art

[0002] In recent years, building structure designs have become increasingly novel. When constructing the upper building, it is necessary to lift multiple steel beams to the required floors, and then assemble the multiple steel beams for construction. After the construction of each floor of the steel beams is completed, a suspended floor structure beam is formed for subsequent pouring of concrete on each floor. In related technologies, when constructing the suspended structure beams of a multi-story building, a small unit of the structure beam is lifted from the ground to the floor to be constructed by a tower crane, and then construction is carried out on it. After the construction is completed, the above steps are carried out for the upper building of the currently constructed floor. That is to say, for the construction of each floor, it is necessary to lift the small unit of the structure beam to this floor by a tower crane after the construction of the lower floor is completed, and continuously repeat the same step to hoist the small unit, which greatly prolongs the construction period. Summary of the Invention

[0052] In some embodiments, in order to add steel beams 310 outside multiple floors of the building body 200, refer to Figures 2 - 8 and refer to Figure 1 , the hanging structure lifting construction method includes the following steps:

[0053] S1. Pre-assemble the steel beams 310 with X (X>1) floors into a structural beam 300 on the ground 100 and / or the top of the buildings around the building body 200, and lift the structural beam 300 to the first floor 240, where the first floor 240 is the top floor among the floors to which the steel beams 310 are to be connected;

[0054] S2. Fix the steel beam 310 at the top layer of the structural beam 300 to the first floor 240;

[0055] S3. Lower the remaining steel beams 310 in the structural beam 300 by Y floors, where Y≥1;

[0056] S4. Install the topmost steel beam 310 among the remaining steel beams 310 on the corresponding floor.

[0057] S5. Repeat steps S3 and S4 to install the steel beams 310 on the corresponding floors respectively.

[0058] It should be noted that in the present invention, the steel beams 310 need to be fixed on the required floors in the building body 200 respectively to form the floor steel beam 310 structure. Subsequently, by pouring concrete on the steel beams 310, a cantilever floor is initially formed. The structural beam 300 is formed by splicing multiple layers of steel beams 310, and each layer of steel beam 310 will be applied to different floors; the first floor 240 is the highest floor among the floors to be constructed in the building body 200; X can be selected according to the number of floors to be actually constructed, and X can be 2, 3, 4... The technical personnel can make an adaptive selection according to the floors to be actually constructed; the technical personnel can also select the number of floors Y by which the structural beam 300 is lowered according to actual needs, for example, lowering 1 floor, lowering 2 floors, etc.

[0059] Compared with the traditional construction method where the steel beam 310 needs to be lifted once from the ground 100 or the top floor of the building for each floor construction, and this is continuously repeated until the construction is completed, in the present invention, the steel beams 310 are first spliced into the structural beam 300, then the structural beam 300 is lifted to the first floor 240, and finally, by lowering the structural beam 300, the steel beams 310 on the structural beam 300 are gradually installed on each floor, saving the construction process of repeated lifting and greatly shortening the construction period.

[0060] Specifically, S1. First, splice the steel beams 310 on the ground 100 and / or the top floor of the building into the structural beam 300, and then lift the structural beam 300 to the highest floor (i.e., the first floor 240) of the required cantilever floor; S2. Subsequently, construct the steel beam 310 on the first floor 240 to fix the steel beam 310 of this floor on the first floor 240; S3. Lower the remaining structural beam 300 by X floors; S4. Fix the topmost steel beam 310 of the structural beam 300 lowered to this floor on this floor.

[0061] In some embodiments, referring to Figures 2 - 4 and referring to Figure 1 , there are multiple buildings with different heights around the building body 200. Step S1 includes: lifting the structural beam 300 at a lower position to dock and fixedly connect with the structural beam 300 of another building with the closest height, completing the docking of all structural beams 300, and lifting the docked structural beam 300 to the first floor 240.

[0062] The embodiment of the present invention can be applied to the building body 200 with multiple buildings of different heights, so that the construction period can also be saved when constructing the building body 200 with multiple buildings of different heights.

[0063] Specifically, referring to Figure 1 , in this embodiment, the structural beam 300 located on the ground 100 is lifted to the top floor of building A210 and docked with the structural beam 300 on the top floor of building A210, and then the docked structural beam 300 is lifted to a position where it can be docked with the structural beam 300 on building B220.

[0064] In some embodiments, referring to Figures 2 - 5 and Figure 11 , there are buildings A210 and B220 around the building body 200. Buildings A210 and B220 are adjacent. Among them, the height of building A210 is lower than that of building B220; S1 includes:

[0065] S1.1. Assemble the structural beam 300 with X1 floors on the top floor of building A210, denoted as the first structural beam, and assemble the structural beam 300 with X2 floors on the top floor of building B220, denoted as the second structural beam, where X2 ≤ X1;

[0066] S1.2. Lift the first structural beam to a position corresponding to the second structural beam;

[0067] S1.3. Connect the first structural beam and the second structural beam to each other;

[0068] S1.4. Lift the docked structural beam 300 to the first floor 240.

[0069] It should be noted that since building B220 is higher than building A210, and the structural beam 300 placed on building B220 can only be assembled up to the height from the top floor of building B220 to the first floor 240 at most. Similarly, the structural beam 300 placed on building A210 can be assembled up to the height from the top floor of building A210 to the first floor 240 at most, resulting in the height of the former structural beam 300 being lower than that of the latter structural beam 300. Therefore, X2 ≤ X1.

[0070] Since the steel beams 310 of building A210 and building B220 need to be spliced ​​eventually during the construction of the floor, if the structural beams 300 on building A210 and building B220 are first lifted to the first floor 240 together and then lowered to the respective required construction floors, and then the steel beams 310 above building A210 and the steel beams 310 above building B220 are spliced, there are relatively large potential safety hazards (that is, workers need to move to the splicing point of the two for construction, and this construction point is in a cantilever state). Therefore, in the embodiment of the present invention, the structural beam 300 of building A210 and the structural beam 300 of building B220 are first docked, and then the docked structural beam 300 is lifted to the first floor 240, which facilitates the construction of the staff and reduces the potential safety hazards of the construction.

[0071] It can be understood that in the process of S1.2, since the structural beam 300 of building B220 is located on the top floor of building B220, when connecting the structural beam 300 of building A210 to the structural beam 300 of building B220, the staff can carry out the connecting construction of the structural beams 300 of the two on the top floor of building B220. Since the top floor of building B220 provides relatively stable support for the staff, it can reduce safety hazards in construction.

[0072] It should be noted that the operator can adaptively adjust X1 and X2 according to actual needs. During the docking process, the operator can choose to splice part or all of the steel beams 310 on the first structural beam with part or all of the steel beams 310 on the second structural beam according to actual needs.

[0073] In some embodiments, reference Figures 2 - 5 and Figure 11 Building 200 is surrounded by building C230, which is adjacent to building A210 or building B220. The height of building C230 is greater than the height of building B220. In the suspended structure lifting construction method, S1.1 further includes: assembling a structural beam 300 having X3 layers on the top floor of building C230, which is recorded as the third structural beam 300, where X3≤X2≤X1.

[0074] Also included between S1.2 and S1.3:

[0075] F1. Lift the connected first structural beam and the second structural beam to a position corresponding to the third structural beam 300;

[0076] F2. Connect the third structural beam 300 to the first structural beam or the second structural beam.

[0077] The present invention provides an embodiment further including a building C230 to illustrate the construction process when there are multiple buildings in the building body 200.

[0078] In some embodiments, reference Figure 9 , S1 also includes:

[0079] Prepare a hoist 400 and several ropes 700 , connect each rope 700 to an adjacent steel beam 310 , place the hoist 400 on the top floor of the building 200 , and connect the hoist 400 to the bottom of the structural beam 300 .

[0080] By using the ropes 700 to bind the adjacent steel beams 310 , it is possible to easily assemble the steel beams 310 of each floor, and it is also possible to easily remove the steel beams 310 from the structural beams 300 to fix them on the floors.

[0081] In some embodiments, referring to Figure 10 , S1 further includes: preparing a lifter 400 and a plurality of connecting rods 800, connecting each connecting rod 800 to an adjacent steel beam 310, arranging the lifter 400 on the top floor of the building 200, and connecting the lifter 400 to the top of the structural beam 300.

[0082] Using the connecting rods 800 to assemble adjacent steel beams 310 can prevent the adjacent steel beams 310 from shaking during the lifting of the structural beam 300.

[0083] In some embodiments, referring to Figure 1 , in order to further reduce the construction period, S1 further includes: using a tower crane 500 to lift the steel beam 310 or the structural beam 300 located on the ground 100 to the top floor of each building.

[0084] During the actual construction process, before the lifter 400 lifts the structural beam 300 to the height of one of the buildings, use the tower crane 500 to lift the structural beam 300 that needs to be placed on the top floor of this building to this building, ensuring that the structural beam 300 during the lifting process can be smoothly docked with the structural beam 300 of this floor of the building when it is lifted to the top floor of this building; on the other hand, before the lifter 400 lifts the structural beam 300 to the height of one of the buildings, the tower crane 500 can also be used to lift the steel beam 310 that needs to be placed on the top floor of this building to this building and assemble the steel beam 310 into a structural beam 300. The above settings can also greatly reduce the construction time of the structural beam 300 during the lifting process.

[0085] It can be understood that in order not to affect the lifting work of the lifter 400 on the structural beam 300, the present invention adopts the tower crane 500 technology to lift each steel beam 310 or structural beam 300 located on the ground 100 that needs to be placed on the top floor of the building to the corresponding top floor of the building, enabling the lifter 400 to work together with the tower crane 500 in terms of time, improving the construction efficiency and shortening the construction time.

[0086] In some embodiments, after S5, it further includes: S6, pouring concrete into the steel beams 310 on each floor.

[0087] Pouring concrete into the steel beams 310 fixed on each floor respectively to form a cantilever floor and integrate it with the original floor.

[0088] In some embodiments, referring to Figure 1 , S1 includes: placing a hanging plate 600 for stacking structural beams 300 on the ground 100 and / or the top floor of the building, splicing steel beams 310 with X (X > 1) layers into a structural beam 300 on the hanging plate 600, and lifting the hanging plate 600 carrying the structural beam 300 to the topmost first floor 240 of the floor where the steel beam 310 to be connected is located.

[0089] Due to the arrangement of the suspension plate 600, the lifter 400 only needs to lift the suspension plate 600 to realize the overall lifting of the structural beam 300, which facilitates the lifting of the structural beam 300.

[0090] In some embodiments, in S1, the lifter 400 is arranged on the top floor of the building 200, and the lifter 400 and the suspension plate 600 are connected by a sling, and the suspension plate 600 is lifted by the lifter 400.

[0091] Specifically, the structural beam 300 is placed on the suspension plate 600, and the lifter 400 is connected to the suspension plate 600 through a lifting rope and can stably lift or lower the suspension plate 600 in the vertical direction.

[0092] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
