[0002] Currently, traditional building structure construction mainly follows a sequential construction process. In the construction of the superstructure, the construction sequence is usually from top to bottom, following the order of columns, beams, and slabs. In the construction of concrete slabs, scaffolding is often required. Workers often neglect the technical and safety requirements when erecting scaffolding, which often leads to the possibility of falls from heights and falling objects, posing a great safety risk to on-site workers. Especially in the construction of large-span spaces and high-span load-bearing scaffolding, once a problem occurs, it will have serious consequences for personal injury and property, and safety cannot be guaranteed. Moreover, the existing construction methods are inefficient and affect the progress of the work. Summary of the Invention

[0057] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0058] Example 1:

[0059] refer to Figures 1 to 2 This embodiment provides a method for the overall lifting construction of beam slab 2, which is used to lift beam slab 2 with only one layer of vertical support 1, including the following steps: S11-S14.

[0060] S11. Construct the bottom vertical support 1 and install the lifting equipment on the bottom vertical support 1.

[0061] Specifically, the bottom vertical support 1 includes two vertical supports 1 on the left and right sides respectively. Each end of the beam 2 is connected and fixed with a vertical support 1. The lifting equipment may include a hydraulic lifter 301 and a steel strand 302. The hydraulic lifter 301 is set on the vertical support 1. One end of the steel strand 302 is connected to the hydraulic lifter 301, and the other end of the steel strand 302 is used to apply a lifting force to the beam 2.

[0062] S12. Construct the first beam slab 2 on the bottom foundation base 6.

[0063] Specifically, the foundation base 6 is set on the ground to facilitate the construction of the first beam slab 2.

[0064] S13. After using the lifting equipment to lift the first beam 2 to the designated elevation, fix the first beam 2 on the bottom vertical support 1.

[0065] Since the vertical support 1 has only one layer, the first beam slab 2 can be permanently fixed to the vertical support 1.

[0066] S14. Lift the equipment to relieve pressure and dismantle the lifting equipment.

[0067] The beam and slab 2 overall lifting construction method provided in this embodiment transfers the construction position of beam and slab 2 from a high place to the ground, greatly reducing the amount of work at height, effectively avoiding the risk of construction personnel falling from height, and preventing objects from falling and injuring ground workers during construction, thus improving construction safety. In addition, during the construction process, while the vertical support 1 is being erected, the beam and slab 2 is being constructed at the bottom layer. The two processes can be carried out simultaneously, which can improve work efficiency and shorten the construction period.

[0068] Example 2:

[0069] refer to Figures 1 to 2 This embodiment provides a method for the overall lifting construction of beams and slabs 2, which is used to lift several beams and slabs 2 of multi-layer vertical supports 1, including the following steps: S21-S29.

[0070] S21. Construct the bottom vertical support 1, and install the lifting equipment on the bottom vertical support 1. The structure of the lifting equipment can be the same as in Example 1.

[0071] S22. Construct the first beam slab 2 on the bottom foundation base 6. Steps S21 and S22 can be performed simultaneously.

[0072] S23. After the first beam 2 is lifted to the designated elevation using the lifting equipment, the first beam 2 is temporarily fixed to the bottom vertical support 1. At this time, the first beam 2 has been shaped and therefore does not need to be reinforced by the foundation base 6, and can be lifted directly.

[0073] S24. Lift the equipment to relieve pressure, dismantle the lifting equipment, and continue to build at least one upper vertical support 1 on the existing vertical support 1. At the same time, carry out the construction of the next beam slab 2 on the foundation base 6.

[0074] On top of the existing vertical support 1, build another upper vertical support 1, or build multiple upper vertical supports 1, and then lift the first beam slab 2.

[0075] S25. Install the lifting equipment on the top vertical support 1. That is, install the lifting equipment on the top vertical support 1.

[0076] S26. Using lifting equipment, lift the first beam 2 to the designated elevation position of the upper vertical support 1, and fix the first beam 2 on the upper vertical support 1.

[0077] The first beam 2 can be fixed on a vertical support 1 between the bottom vertical support 1 and the top vertical support 1, or it can be fixed on the top vertical support 1.

[0078] S27. Using the lifting equipment, lift the next beam 2 to the designated elevation position of the vertical support 1 below the lifted beam 2, and fix the next beam 2 on the corresponding vertical support 1, until all beams 2 are lifted and fixed on the corresponding vertical supports 1 from top to bottom.

[0079] It should be noted that after all beams 2 are lifted and fixed on the corresponding vertical supports 1, there can be one or more vertical supports 1 between two adjacent beams 2, or all of them can be set adjacent to each other, that is, there are no gaps between any two adjacent beams 2.

[0080] S28. Repeat steps S24-S27 above to lift and finally fix several beams and slabs 2 of the multi-story building from low to high.

[0081] S29. Lift the equipment to relieve pressure and dismantle the lifting equipment.

[0082] Specifically, the third, fourth...nth vertical supports 1 are sequentially built on the upper vertical support 1, where n is a positive integer greater than 1. While building the vertical support 1 at the top level, the corresponding third, fourth...nth beam slabs 2 are built at the bottom level. Each time a layer of vertical support 1 is built upwards, the existing beam slabs 2 are raised one or more layers upwards from top to bottom according to steps S26-S27. Then, the newly built beam slab 2 is raised to the designated elevation position of the bottom level. In summary, after all the beam slabs 2 are raised, the first beam slab 2 fixed on the nth vertical support 1, the second beam slab 2 fixed on the (n-1)th vertical support 1, and so on, the nth beam slab 2 fixed on the first (bottom) vertical support 1.

[0083] The beam and slab 2 overall lifting construction method provided in this embodiment is for multi-story buildings. Vertical supports 1 are built layer by layer upwards, and the beam and slab 2 is lifted layer by layer upwards. It is suitable for the construction of beam and slab 2 in multi-story buildings and has good stability.

[0084] Example 3:

[0085] refer to Figures 1 to 2This embodiment provides a method for the overall lifting construction of beams and slabs 2, which is used to lift several beams and slabs 2 of multi-layer vertical supports 1, including the following steps: S31-S311.

[0086] S31: Construct the bottom vertical support 1, continue to construct at least one upper vertical support 1 on the bottom vertical support 1, and install the lifting equipment on the top vertical support 1.

[0087] First, construct multi-layered vertical supports 1, then lift the beams and slabs 2.

[0088] S32. Construct the first beam slab 2 on the bottom foundation base 6.

[0089] Steps S31 and S32 can be performed simultaneously.

[0090] S33. After using the lifting equipment to lift the first beam 2 to the designated elevation position, temporarily fix the first beam 2 to the uppermost vertical support 1.

[0091] S34. On the foundation base 6, construct the next beam slab 2, and then use the lifting equipment to lift the next beam slab 2 to the designated elevation position of the vertical support 1 below the first beam slab 2, and fix the next beam slab 2 on the vertical support 1.

[0092] In step S33, if the foundation base 6 and the first beam slab 2 are lifted at the same time, then step S34 also includes unloading the lifting equipment to lower the foundation base 6 to the initial position, and then carrying out the construction of the next beam slab 2 on the foundation base 6.

[0093] S35. Repeat step S34 above until all beams and slabs 2 are lifted and fixed to the corresponding vertical supports 1 from top to bottom.

[0094] S36. Lift the equipment to relieve pressure, dismantle the lifting equipment, and continue to build at least one upper vertical support 1 on the existing vertical support 1. At the same time, carry out the construction of the next beam slab 2 on the foundation base 6.

[0095] S37. Install the lifting equipment on the top vertical support 1.

[0096] S38. Using lifting equipment, lift the first beam 2 to the designated elevation position of the newly built uppermost vertical support 1, and fix the first beam 2 on the newly built uppermost vertical support 1.

[0097] S39. Using the lifting equipment, lift the next beam 2 to the designated elevation position of the vertical support 1 below the lifted beam 2, and fix the next beam 2 on the corresponding vertical support 1, until all beams 2 are lifted and fixed on the corresponding vertical supports 1 from top to bottom.

[0098] S310. Repeat steps S34-S39 above to lift and finally fix several beams and slabs 2 of the multi-story building from low to high.

[0099] S311. Lift the equipment to relieve pressure and dismantle the lifting equipment.

[0100] The beam and slab 2 lifting construction method provided in this embodiment is for multi-story buildings. Each floor of the building requires one vertical support 1 and one beam and slab 2. This method can build multiple vertical supports 1 and lift multiple beams and slabs 2 at a time. The lifting equipment continuously lifts the beams and slabs 2 of the multi-story building and then dismantles them. Multiple beams and slabs can be lifted at a time, which further improves work efficiency.

[0101] See Figure 3-10 Taking the beam and slab lifting construction of a six-story building as an example, two layers of vertical supports 1 are erected in a single operation: (e.g.) Figure 3-4 First, construct the first and second layers of vertical supports 1 on the ground, and then lift the two beams 2; Figure 5-7 On the second-layer vertical support 1, continue to build the third and fourth layers of vertical supports 1, and lift the two previous beams 2 upwards two layers from top to bottom and fix them. Then construct two more beams 2 on the ground, lift and fix them on the first and second-layer vertical supports 1 respectively; as follows Figure 8-10 On the fourth vertical support 1, the fifth and sixth vertical supports 1 are built. The previous four beams 2 are lifted two layers from top to bottom and fixed. Then, two beams 2 are constructed on the ground and lifted and fixed on the first and second vertical supports 1 respectively, thus completing the lifting work of the beams 2.

[0102] The beam and slab 2 overall lifting construction method provided by this invention transfers the construction position of beam and slab 2 from a high place to the ground, greatly reducing the amount of work at height, effectively avoiding the risk of construction personnel falling from height, and preventing objects from falling and injuring ground workers during construction, thus improving construction safety. In addition, during the construction process, while the vertical support 1 is being built on the top floor, the beam and slab 2 is being constructed on the bottom floor. The two processes can be carried out simultaneously, which can improve work efficiency and shorten the construction period.

[0103] As a preferred embodiment, the lifting device in the above embodiments 1-3 includes a hydraulic lifter 301 and a steel strand 302. A guide frame (not shown) can be provided at the lifting device to guide the steel strand 302. The hydraulic lifter 301 is mounted on the vertical support 1. One end of the steel strand 302 is connected to the hydraulic lifter 301. The hydraulic lifter 301 is a mechanical device composed of hydraulic components with lifting and synchronous control functions. In this invention, it is used to lift the beam 2 to a specified height. The other end of the steel strand 302 is used to apply a lifting force to the beam 2.

[0104] In a preferred embodiment, the other end of the steel strand 302 is connected to a reinforcing hanging plate 401, which provides support. When the beam slab 2, constructed on the foundation base 6, is lifted for the first time, the foundation base 6 and the beam slab 2 are lifted simultaneously. The reinforcing hanging plate 401 is positioned below the foundation base 6 and closely adheres to its bottom surface. After the beam slab 2 has completed its first lift, the foundation base 6 is lowered to the ground, and the next beam slab 2 is constructed on the foundation base 6. During the initial lift of the beam slab 2, the foundation base 6 provides reinforcement. After all beam slab 2 construction and lifting are completed, the foundation base 6 needs to be removed. When the beam slab 2 is lifted a second or subsequent time, it is already shaped, so there is no need to use the foundation base 6 for reinforcement again.

[0105] Both the beam slab 2 and the foundation base 6 have holes 402 for the steel strand 302 to pass through. The diameter of the reinforcing plate 401 is larger than the diameter of the hole 402. Reinforcing bars can also be installed in the hole 402 to reinforce the connection between the steel strand 302 and the beam slab 2.

[0106] As a preferred implementation, in the above embodiments 1-3, before using the lifting equipment to lift the beam plate 2, the steel strand 302 is first tensioned for pre-lifting to check whether the steel strand 302 is securely fixed. If no breakage, fracture, or loosening of the steel strand 302 occurs during pre-lifting, it indicates that the steel strand 302 is securely connected and the lifting equipment meets the load-bearing requirements, and the lifting work can be carried out normally. Otherwise, it is necessary to check the connection points and reconnect them, replace the steel strand 302, or replace the hydraulic lifting device 301, etc.

[0107] When the beam slab 2 on the foundation base 6 is lifted for the first time, when the beam slab 2 is lifted to 50-80cm above the ground (the height can be set according to actual needs, so that the workers can stand on the ground to remove the attachments), the attachments on the beam slab 2 are removed. This can prevent the risk of falling objects from height caused by debris falling during the lifting of the beam slab 2, and further improve the construction safety. Attachments such as formwork or other debris during the construction of the beam slab 2 are examples of such attachments.

[0108] As a preferred implementation, in the above embodiments 1-3, before each unloading of the lifting equipment, the steel strand 302 is loosened to check whether the beam 2 to be lifted is securely fixed. If the position of the beam 2 does not change as the steel strand 302 is loosened, it indicates that the beam 2 is securely fixed and the unloading work of the lifting equipment can be carried out. Otherwise, the fixing points of the beam 2 need to be checked and reinforced.

[0109] In a preferred embodiment, in the above embodiments 1-3, a fixing assembly is provided at the connection between the beam plate 2 and the vertical support 1 used for temporarily fixing the beam plate 2. The fixing assembly preferably includes a first stiffening plate 501 disposed on the vertical support 1 and a second stiffening plate 502 disposed on the beam plate 2. The first stiffening plate 501 and the second stiffening plate 502 are fixed together by bolts. Before the beam plate 2 is lifted, the fixing assembly is used to temporarily fix the beam plate 2, facilitating disassembly for subsequent lifting.

[0110] As a preferred implementation, in the above embodiments 1-3, after the beam slab 2 is constructed on the foundation base 6 and before the beam slab 2 is lifted for the first time, the following steps are also taken: the beam slab 2 is cured to ensure that it reaches the lifting strength and to prevent the beam slab 2 from deforming during the lifting process or after it is fixed.

[0111] As a preferred implementation, in the above embodiments 1-3, when the beam 2 is lifted to the designated elevation position, the elevation and axis position of the beam 2 are first re-measured and then fixed. If the elevation data is accurate and the axis position is not skewed or shifted, the beam 2 can be fixed directly. If the elevation data is inaccurate or the axis position of the beam 2 is skewed or shifted, it needs to be adjusted by lifting equipment.

[0112] As a preferred implementation method, in the above embodiments 1-3, the overall lifting construction method of beam slab 2 further includes: after all vertical supports 1 are completed and all beam slab 2 are lifted, the foundation base 6 is removed. In order to improve the stability of beam slab 2 fixing, after all construction procedures are completed, the connection points between each beam slab 2 and the vertical supports 1 are reinforced and poured to permanently fix the beam slab 2.

[0113] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
