[0002] Reinforced concrete factory buildings are typically multi-story, with numerous pieces of equipment on each floor from the second to the fourth. This equipment is usually in the form of tanks or troughs that penetrate the floor slabs, so openings need to be pre-drilled during construction. After the concrete reaches the required strength, the equipment is hoisted in, and construction of the beams and slabs for the next floor begins after the equipment is installed. However, because the equipment cannot withstand external loads to avoid deformation, its installation significantly impacts the convenience and safety of subsequent beam and slab support erection. Summary of the Invention

[0009] Furthermore, in the above-mentioned formwork construction method for equipment protection, the assembly step further includes: installing each support component in the first unit on the floor slab; wherein each support component is arranged in two rows, each row including: at least three support components, with a preset distance between two adjacent support components; sequentially installing one second unit, multiple third units and another second unit on two corresponding support components in the two rows; installing a protective net at the bottom of the first support frame in each second unit, and installing a protective net at the bottom of the second support frame in each third unit.

[0010] Furthermore, in the above-mentioned template construction method for equipment protection, each first support frame in each second unit includes: two parallel first columns and multiple first connectors; each first connector is disposed between the two first columns, and the two first columns are detachably connected to the two support columns in the corresponding support assembly; each second support frame in each third unit includes: two parallel second columns and multiple second connectors; each second connector is disposed between the two second columns, and the two second columns are detachably connected to the two support columns in the corresponding support assembly.

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1 , Figure 1 A flowchart illustrating a formwork construction method for equipment protection provided in an embodiment of the present invention is shown. As illustrated, the formwork construction method for equipment protection includes the following steps:

[0022] Step S1: Determine the dimensions of the steel frame based on the dimensions of the largest piece of equipment.

[0023] Specifically, the dimensions of the steel frame are determined based on the dimensions of the largest device among the devices 10 to be installed.

[0024] In this embodiment, a steel frame with a span of 4.5 meters, a height of 4.5 meters, and a column spacing of 1 meter is selected, which can meet the protection requirements of all equipment.

[0025] In step S2, based on the determined dimensions of the steel frame, multiple steel frame units are manufactured.

[0026] Specifically, the specifications and structural form of each component required for the fabrication of the steel frame are calculated based on the superstructure load.

[0027] See Figures 2 to 3 The components are assembled to form multiple steel frame units, each steel frame unit including: a first unit 2, two second units 3 and multiple third units 4.

[0028] See Figures 2 to 3 The first unit 2 includes multiple support components 21. The support components 21 are spaced apart and arranged in two rows with a certain distance between them. The support components 21 in each row are spaced apart, and the positions of the support components 21 in the two rows correspond one-to-one.

[0029] Each support component 21 includes a connector 211 and two support columns 212. The two support columns 212 are arranged side-by-side, with a preset distance between them. This preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on it. The connector 211 is disposed between the two support columns 212 so that the support components 21 form a single unit.

[0030] In specific implementation, there can be two or more connectors 211, and each connector 211 can be arranged horizontally, inclined, or crosswise on the two support columns 212. This embodiment does not impose any restrictions on this.

[0031] See Figures 2 to 3 Each second unit 3 includes: a first support frame 31, two first support frames 32, and two first connecting beams 33. The two first support frames 32 are arranged side-by-side with a certain distance between them, and each of the two first support frames 32 corresponds one-to-one with one of the two support components 21. The bottom of each first support frame 32 ( Figure 3 The lower part (shown) is detachably connected to the corresponding support assembly 21. The first support frame 31 is horizontally mounted on the top of the two first support frames 32. Figure 3 (As shown in the upper part), the two first support frames 32 and the first support frame 31 form a gate-shaped structure.

[0032] In practice, the two first support frames 32 are connected one-to-one with the two corresponding support components 21 in the two rows.

[0033] Each first support frame 32 includes two first columns 321 and multiple first connectors 322. The two first columns 321 are arranged side-by-side with a certain distance between them, and each first connector 322 is disposed between the two first columns 321 to connect them together. The two first columns 321 are detachably connected to the two support columns 212 in the corresponding support assembly 21, preferably by bolts.

[0034] In specific implementation, each first connector 322 can be arranged horizontally, inclined, or intersecting on the two first columns 321. This embodiment does not impose any restrictions on this.

[0035] The first support frame 31 can be quadrilateral, specifically including two parallel horizontal beams 5 and two parallel vertical beams 6. Each horizontal beam 5 has two ends connected to the ends of the two vertical beams 6 on the same side, forming a quadrilateral frame. The horizontal beams 5 are positioned on top of the first support frame 32, and the vertical beams 6 are positioned on top of the two first support frames 32.

[0036] Two first connecting beams 33 are respectively disposed on the same side of the two ends of the first support frame 31. Specifically, the two first connecting beams 33 are disposed at the two ends of the same vertical beam 6, and the two first connecting beams 33 extend away from the first support frame 31.

[0037] See Figures 2 to 3Each third unit 4 includes: a second support frame 41, two parallel second support frames 42, and four parallel second connecting beams 43. The two second support frames 42 are arranged side-by-side with a certain distance between them, and each second support frame 42 corresponds one-to-one with one of the two support components 21. The bottom of each second support frame 42 ( Figure 3 The lower part (as shown) is detachably connected to the corresponding support assembly 21. The second support frame 41 is horizontally mounted on the top of the two second support frames 42. Figure 3 (as shown in the upper part), then the two second support frames 42 and the second support frame 41 form a gate-shaped structure.

[0038] In practice, the two second support frames 42 are connected one-to-one with the two corresponding support components 21 in the two rows.

[0039] Each second support frame 42 includes two second columns 421 and multiple second connectors 422. The two second columns 421 are arranged side-by-side with a certain distance between them, and each second connector 422 is disposed between the two second columns 421 to connect them together. The two second columns 421 are detachably connected to the two support columns 212 in the corresponding support assembly 21, preferably by bolts.

[0040] In specific implementation, each second connector 422 can be arranged horizontally, inclined, or intersecting on the two second columns 421. This embodiment does not impose any restrictions on this.

[0041] The second support frame 41 can be quadrilateral, specifically including two parallel horizontal beams 5 and two parallel vertical beams 6. Each horizontal beam 5 has two ends connected to the ends of the two vertical beams 6 on the same side, forming a quadrilateral frame. The horizontal beams 5 are positioned on top of the second support frame 42, and the vertical beams 6 are positioned on top of the two second support frames 42.

[0042] Four second connecting beams 43 are respectively disposed on both sides of the two ends of the second support frame 41. Specifically, two second connecting beams 43 are disposed on the two ends of one vertical beam 6, and two second connecting beams 43 are disposed on the two ends of the other vertical beam 6. Furthermore, all four second connecting beams 43 extend away from the second support frame 41.

[0043] In practice, the first support frame 31 is equipped with lifting lugs 8, and the second support frame 41 is also equipped with lifting lugs 8 to facilitate hoisting.

[0044] In practice, a DN32 sleeve is welded to the bottom of each support column 212 to facilitate the installation of casters and the movement of the first unit 2. Furthermore, a DN32 sleeve is welded to the bottom of each first column 321 and the bottom of the second column 421 to facilitate the installation of casters and the movement of the second unit 3 or the third unit 4.

[0045] Step S3: Install the equipment onto the floor slab and cover it.

[0046] Specifically, after the concrete strength of the floor slab reaches the design requirements, the equipment 10 is hoisted and covered with a tarpaulin to protect the equipment 10 and prevent cement slurry from contaminating it.

[0047] Assembly step S4 involves hoisting each steel frame unit onto the floor slab and assembling them to form a steel frame.

[0048] Specifically, the required steel frame unit components are determined based on the size of the equipment, and then hoisted to the designated location and assembled using a tower crane.

[0049] Assembly step S4 further includes:

[0050] Sub-step S41: Install each support component in the first unit on the floor slab; wherein each support component is set in two rows, each row includes: at least three support components, and there is a preset distance between two adjacent support components.

[0051] Specifically, see Figures 2 to 3 Two lines are set on the floor slab, and the positions of the two lines correspond to the design positions. A row of support components 21 is set at the position of each line, and at least three support components 21 are set in each row. There is a preset distance between two adjacent support components 21 in each row. The preset distance can be determined according to the actual situation. This embodiment does not impose any restrictions on this.

[0052] In practice, each support column 212 in each support component 21 is installed on the floor slab by expansion bolts.

[0053] Sub-step S42 involves sequentially installing one second unit, multiple third units, and another second unit on two corresponding support components in the two rows.

[0054] Specifically, from left to right, one second unit 3, multiple third units 4, and another second unit 3 are installed on two support components 21 at corresponding positions in the two rows. The two second units 3 are placed on the outermost side, and each third unit 4 is sandwiched between the two second units 3.

[0055] Each first support frame 32 in each second unit 3 is bolted to the support component 21 at the corresponding position, and each second support frame 42 in each third unit 4 is bolted to the support component 21 at the corresponding position.

[0056] The two first connecting beams 33 in each second unit 3 are detachably connected to the two second connecting beams 43 on the corresponding side in the adjacent third unit 4. Preferably, the two first connecting beams 33 correspond one-to-one with the two corresponding second connecting beams 43 and are connected by bolts.

[0057] The second connecting beams 43 in two adjacent third units 4 are detachably connected. Specifically, in two adjacent third units 4, the two second connecting beams 43 on the same side in one third unit 4 are connected to the two second connecting beams 43 on the corresponding side in the other third unit 4 by bolts.

[0058] Sub-step S43: Install a protective net at the bottom of the first support frame in each second unit, and install a protective net at the bottom of the second support frame in each third unit.

[0059] Specifically, the protective net 9 is installed to prevent materials or personnel from falling.

[0060] Installation step S5: Erect a beam and slab structure support frame on the upper part of the steel frame and pour the upper beam and slab concrete.

[0061] Specifically, see Figures 2 to 4 After the installation of each steel frame unit is completed, the frame units form a steel frame. A beam-slab structure support frame 7 is erected on the upper part of the steel frame. The spacing and step distance of the uprights of the beam-slab structure support frame 7 are determined according to the safety plan. The support frame above the steel frame 1 and the surrounding support frame are connected into a whole by reinforcing rods to ensure the stability of the beam-slab structure support frame 7.

[0062] Pre-embed lifting rings or steel plates before pouring the concrete for the upper beams and slabs.

[0063] In dismantling step S6, after the beam and slab concrete reaches the demolding condition, the beam and slab structural support frame and steel frame are removed, and the removed steel frame is hoisted to the upper floor slab.

[0064] Specifically, once the concrete of the beam and slab meets the conditions for demolding, the beam and slab structural support frame is removed and the structure is cleaned.

[0065] Install the hoisting device on the lifting rings, connect the traction components to each steel frame unit and the hoisting device, disassemble each steel frame unit, and use the hoisting device and traction components to hoist each steel frame unit to the ground. Then, use the hoisting device to hoist the dismantled steel frame to the upper floor slab.

[0066] Specifically, the hoisting device can be a manual hoist, and the pulling component can be an iron chain. The manual hoist is installed on the pre-embedded lifting ring, and four iron chains are used to connect the lifting lugs on the steel frame unit. The bolts on each frame unit are then removed, one unit at a time, and slowly lowered to the ground. Casters are then installed on each frame unit, and the units are moved to the unloading platform. From there, they are hoisted to the upper floor.

[0067] Repeat assembly step S4, installation step S5, and disassembly step S6 until the beams and slabs of each floor are completed.

[0068] As can be seen, in this embodiment, the size of the steel frame is first determined based on the size of the largest equipment, and multiple steel frame units are fabricated. Then, the equipment is installed on the floor slab, and each steel frame unit is hoisted and assembled into a steel frame. Next, a beam-slab structural support frame is erected on the upper part of the steel frame, and the upper beam-slab concrete is poured to form a beam-slab. Then, the beam-slab structural support frame and the steel frame are dismantled, and the steel frame is hoisted to the next floor slab. The above steps are repeated to complete the construction of each layer of beams and slabs. By assembling the steel frame to support the beam-slab structural support frame, and using the beam-slab structural support frame to construct the beams and slabs, the operation is simple and easy to implement. It does not affect the erection of the beam-slab structural support frame. Furthermore, the size of the steel frame is determined based on the size of the largest equipment, which can effectively protect the equipment and solve the problem of the inconvenience of erecting beam-slab support frames in the prior art. In addition, each steel frame unit can be reused, saving materials and shortening the construction period.
