[0030] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 As shown, the electric screw 2-type construction support device provided in the present application includes: a first column A, a second column B and a nut C.

[0032] The first column A and the second column B each include: a guide rail 1 , a screw rod 2 installed on the guide rail 1 , a motor 3 installed on the guide rail 1 , a support assembly 4 installed on the guide rail 1 , and a fixing assembly 5 .

[0033] The screw rod 2 is roughly parallel to the guide rail 1. The motor 3 can be installed on the upper end of the guide rail 1. The upper end of the screw rod 2 is connected to the motor 3, so that it can be driven to rotate by the motor 3. A fixing block 15 is provided on one side of the guide rail 1, and the lower end of the screw rod 2 is installed on the fixing block 15.

[0034] The screw rod 2 of the first column A and the screw rod 2 of the second column B are both threadedly connected with the nut C. When the screw rod 2 of the first column A rotates, the nut C climbs up or falls down, thereby driving the second column B to climb up or fall down. Similarly, when the screw rod 2 of the second column B rotates, the nut C climbs up or falls down, thereby driving the first column A to climb up or fall down.

[0035] like Figure 2 As shown, during construction, the first column A and the second column B of the electric screw 2 type construction support device are fixed on the floor slab 8 that has been poured and cured. Figure 2 In the figure, the first column A is inserted into the reserved hole 81 of the N-th floor slab 8 and is fixedly supported on the N-th floor slab 8 through the fixing component 5, and the second column B is inserted into the reserved hole 81 of the N+1-th floor slab 8 and is fixedly supported on the N+1-th floor slab 8 through the fixing component 5.

[0036] After the first column A is fixed, the horizontal prefabricated components 7 are laid on the supporting assembly 4 of the first column A, and then the mold is closed for casting and curing to form the N+2-th floor slab 8. During the curing period, the supporting assembly 4 of the first column A supports the N+2-th floor slab 8. After the curing is completed, the first column A is allowed to climb two floors and then fixed (fixed on the N+2-th floor slab 8), and then the horizontal prefabricated components 7 are laid on the supporting assembly 4 of the first column A, and then the mold is closed for casting and curing to form the N+4-th floor slab 8.

[0037] After the second column B is fixed, the horizontal prefabricated components 7 are laid on the supporting assembly 4 of the second column B, and then the mold is closed for casting and curing to form the N+3th floor slab 8. During the curing period, the supporting assembly 4 of the second column B supports the N+3th floor slab 8. After the curing is completed, the second column B is climbed two floors and then fixed (fixed on the N+3th floor slab 8), and then the horizontal prefabricated components 7 are laid on the supporting assembly 4 of the second column B, and then the mold is closed for casting and curing to form the N+5th floor slab 8.

[0038] The first column A and the second column B climb upward alternately until the pouring and curing of the top floor slab 8 is completed.

[0039] Compared with scaffolding support, the electric screw 2 type construction support device provided by the present application is used to support the horizontal prefabricated components 7. The turnover material consumption is less and the manpower demand is relatively less, and the construction safety is higher. Moreover, the upper floor slab 8 can be poured during the maintenance of the lower floor slab 8. The maintenance and pouring can be carried out at the same time. Therefore, the construction period can be shortened and the construction cost can be reduced. In addition, the electric screw 2 type construction support device provided by the present application drives the screw 2 through the motor 3 to realize the upward climbing or downward descending of the column. The lifting distance is accurate and can be powered by a battery to avoid complicated line layout, and the self-locking function of the thread ensures the support reliability.

[0040] More specifically, Figure 1 As shown, the guide rail 1 of the first column A and the guide rail 1 of the second column B are both provided with an upper slider 13, a lower slider 14 and a slide groove 12. Figure 4 As shown, the upper slider 13 and the lower slider 14 of the first column A are slidably guided with the slide groove 12 of the second column B, and the upper slider 13 and the lower slider 14 of the second column B are slidably guided with the slide groove 12 of the first column A. In this way, the first column A and the second column B can alternately climb as guide rails 1, thereby improving the stability of column climbing.

[0041] More specifically, Figure 5-Figure 7 As shown, the support assembly 4 includes a foldable bracket and an electric push rod 41 for driving the foldable bracket to unfold or fold, and the foldable bracket forms a horizontal support surface when it is unfolded. In the illustrated embodiment, a support assembly 4 is installed on both sides of each column, and when the two support assemblies 4 are unfolded, the horizontal support surfaces of the two are flush. After the foldable bracket is unfolded, it can support the horizontal prefabricated component 7 with a larger area. After the foldable bracket is folded, it can pass through the reserved hole 81 on the floor 8, so as not to affect the upward climbing or downward descent of the column. The electric push rod 41 makes the unfolding position or folding position of the foldable bracket more accurate. If it is not unfolded in place, it may not be able to stably support the horizontal prefabricated component 7. Therefore, the accurate unfolding position is conducive to improving the support reliability. The motor 3 and the electric push rod 41 can be remotely controlled.

[0042] More specifically, Figure 5-Figure 7 As shown, the foldable support includes a vertical rod 42, a first support rod 43, a second support rod 44 and a third support rod 45. The vertical rod 42 is fixedly connected to the guide rail 1. The first support rod 43 is rotatably connected to the vertical rod 42. One end of the second support rod 44 is rotatably connected to the first support rod 43. The other end of the second support rod 44 is rotatably connected to one end of the third support rod 45. The other end of the third support rod 45 is rotatably connected to the vertical rod 42. One end of the electric push rod 41 is slidably and rotatably connected to the vertical rod 42. The other end of the electric push rod 41 is rotatably connected to the third support rod 45. In the unfolded state, the first support rod 43 is horizontal, and the second support rod 44 and the third support rod 45 are tilted and supported below the first support rod 43. This structural form of the support has a high support reliability. Of course, the structural form of the foldable support is not limited thereto, as long as it can support the horizontal prefabricated component 7 after unfolding and does not affect the climbing or descending of the column after folding.

[0043] More specifically, Figure 1 As shown, a storage compartment 11 can be provided on the side of the guide rail 1, and the foldable bracket is located in the storage compartment 11 when it is folded. In this way, the cross-sectional area of ​​the column after the foldable bracket is folded is relatively small, so the reserved hole 81 on the floor 8 for the column to pass through can be designed to be smaller, so as to facilitate subsequent filling.

[0044] More specifically, Figure 1 As shown, the fixing assembly 5 includes at least one fixing member 51, which is inserted horizontally into the reserved hole at the bottom of the column. Both ends of the fixing member 51 are supported on the poured and cured floor slab 8. This fixing structure is simple and reliable, and the fixing member 51 can be easily removed when the column needs to climb. After the fixing member 51 is removed, the column can smoothly pass through the reserved hole 81 on the floor slab 8 and climb upward.

[0045] More specifically, the fixing assembly 5 may further include at least two distribution beams 52, the distribution beams 52 are supported on the poured and cured floor slab 8, and the fixing member 51 is supported across at least two distribution beams 52. In this way, the load of the column can be effectively dispersed, so that the column is not easily deformed. In the illustrated embodiment, the fixing assembly 5 is provided with three distribution beams 52, two longitudinal beams, and one transverse beam, the transverse beam is connected between the two longitudinal beams, the fixing member 51 is across the two longitudinal beams, the two longitudinal beams are abutted against the two opposite sides of the column, and the transverse beam is abutted against the other side of the column, forming a semi-enclosed structure for the column, thereby limiting the horizontal position of the column, which is more conducive to the stability of the position of the column.

[0046] More specifically, Figure 2 and Figure 3 As shown, the electric screw 2 type construction support device can further include a limiter 6, which is inserted into the reserved holes 81 on the floor slab 8 and the gaps between the columns inserted therein, which can further limit the horizontal position of the columns and is more conducive to the stability of the position of the columns.

[0047] More specifically, in the illustrated embodiment, both the fixing member 51 and the limiting member 6 are wedge-shaped structures, which have a better limiting effect and are convenient for disassembly.

[0048] The above specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
