Description

Technical Field

[0001] This invention relates to the field of structural slab lowering formwork technology, specifically to a structural slab lowering formwork support device and method. Background Technology

[0002] Structural slab lowering refers to lowering the structural elevation of a floor slab or roof slab. Different rooms in a building have different functions, and therefore use different floor and floor finishing materials—stone, floor tiles, wood flooring, terrazzo, fine stone concrete, cement, etc. The construction methods of various materials are different, and their thicknesses are also different. Among them, the waterproofing of sloped surfaces is the thickest, such as in bathrooms, shower rooms, and kitchens. This creates a difference in floor level between rooms with different materials. When the difference in floor level is greater than 30 mm, the "slab lowering" method is used to lower the elevation of the floor slab on the side with the larger thickness, so that the floors with different materials are basically level after completion. This avoids too many small steps and slopes that can create obstacles and cause inconvenience to users. During the construction of structural slab lowering, suspended formwork is essential.

[0003] In modern life, people usually fix the suspended formwork with nails to ensure its stability. However, during the concrete pouring process, the outside of the suspended formwork is subjected to great pressure, while the inside of the formwork is hollow, which makes the formwork prone to deformation and causes construction problems. In addition, fixing the suspended formwork with nails results in low fixing efficiency and high manual labor intensity. Summary of the Invention

[0004] This invention provides a structural slab lowering formwork support device and method, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a structural slab lowering formwork support device and method, comprising a formwork, wherein a closed plate is uniformly arranged inside the formwork, and a barrier plate is provided at one end of the formwork;

[0006] The top of the closed plate is provided with a straight support plate that supports the inner wall of the hanging mold and a two-way threaded rod that is adjusted by the straight support plate. The bottom of the straight support plate is provided with a spring telescopic rod that connects the hanging mold and the closed plate.

[0007] The lifting mold has clamping columns evenly arranged at both ends, and a moving rod for driving the clamping columns and a fixing screw for fixing the moving rod are arranged on the outside of the lifting mold.

[0008] Preferably, one end of the sealing plate and the barrier plate is machined with a limit post, and the other end of the sealing plate and the end of the lifting mold are provided with limit grooves at the positions corresponding to the limit posts. Two adjacent sealing plates, the sealing plate and the lifting mold, and the sealing plate and the barrier plate are connected by the limit posts and the limit grooves.

[0009] Preferably, a bidirectional threaded rod is embedded and rotatably connected inside the closed plate. A movable block is threadedly connected to the outside of the bidirectional threaded rod. A slanted support frame is installed at the top end of the movable block by screws. A straight support plate is installed at one end of the slanted support frame by screws. A placement plate is placed between the two straight support plates. A fixing rod is installed on the bottom surface of the straight support plate. A spring telescopic rod is installed at the bottom of the fixing rod by screws. The bottom of the spring telescopic rod is inside the closed plate.

[0010] Preferably, a rotating handle is fixedly sleeved on the outer side of the bidirectional threaded rod, the end face of the straight support plate is in contact with the inner wall of the lifting mold, and a placement groove is opened at both ends of the straight support plate, and the placement plate is placed inside the placement groove.

[0011] Preferably, the longitudinal section of the limiting block is T-shaped, the end face of the moving plate is provided with an inclined angle, and the top surface of the limiting plate is in contact with the top surface of the closing plate.

[0012] Preferably, the closed plate has sliding connection limit blocks uniformly embedded inside, and the top of the limit blocks is equipped with a movable plate by screws. One end of the two movable plates is equipped with a limit plate by screws.

[0013] Preferably, both ends of the lifting mold are provided with sliding grooves, and a slider is slidably connected inside the sliding groove. A moving rod is installed at one end of the slider by a screw, and an insertion post is slidably connected inside the moving rod. A clamping post is installed at the bottom of the insertion post by a screw, and a fixing screw is threaded inside the slider.

[0014] Preferably, the longitudinal sections of both the slide groove and the slider are convex, the top surface of the slide groove is provided with an installation groove, and the fixing screw is slidably connected inside the installation groove.

[0015] Preferably, one end face of the fixing screw is in contact with the top surface of the lifting mold, and the clamping column is provided with an insertion groove at the position corresponding to the insertion column, and the outer diameter of the insertion column is equal to the inner diameter of the insertion groove.

[0016] Preferably, both ends of the lifting mold are connected to connecting screws by threads, and mounting blocks are slidably connected to the outer side of the connecting screws. One end of the mounting block is fitted with a mounting post by a screw.

[0017] A method of using a structural slab lowering formwork support device includes:

[0018] S1: Select different lengths and widths of suspended formwork according to different construction sites, and select different specifications and quantities of enclosing plates and barrier plates according to different lengths and widths of suspended formwork;

It facilitates the assembly of the suspended formwork, the sealing plate, and the barrier plate, making the suspended formwork suitable for different construction sites, expanding its applicability, and facilitating the fixing of the placed formwork, thus improving the efficiency of formwork fixing. This solves the problem of low fixing efficiency and high labor intensity caused by using nails for fixing in daily life. Furthermore, during concrete pouring, the formwork can be squeezed from all sides of the clamping column, further ensuring its stability and ensuring normal construction and construction results. During use, the straight support plate and the placement plate provide support to the inner wall of the formwork, preventing excessive pressure on the outer side of the formwork during subsequent concrete pouring, which could cause deformation and ensure the stability of the formwork. This, in turn, ensures the construction of the lowered slab structure. In conjunction with the fixing rod and the spring telescopic rod, a triangular support is formed, further enhancing the internal support strength of the formwork and ensuring its stability.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example: Figure 1-7 As shown, the present invention provides a technical solution: a structural lowering plate formwork support device and method, including a formwork 1, with closed plates 2 uniformly arranged inside the formwork 1, and a barrier plate 3 provided at one end of the formwork 1. Limiting posts are machined at one end of both the closed plates 2 and the barrier plate 3. Limiting grooves are formed at the other end of the closed plates 2 and at the corresponding positions of the limiting posts at one end of the formwork 1. Two adjacent closed plates 2, closed plates 2 and the formwork 1, and closed plates 2 and the barrier plate 3 are connected by limiting posts and limiting grooves, facilitating the connection between two adjacent closed plates 2, closed plates 2 and the formwork 1, and closed plates 2 and the barrier plate 3. Positioning can be performed when two adjacent closed plates 2, closed plates 2 and the formwork 1, and closed plates 2 and the barrier plate 3 are connected, ensuring the stability of the two adjacent closed plates 2, closed plates 2 and the formwork 1, and closed plates 2 and the barrier plate 3 after connection.

[0034] A bidirectional threaded rod 4 is embedded inside the closed plate 2 and rotated. A movable block 5 is connected to the outside of the bidirectional threaded rod 4 by a thread. A slanted support frame 6 is installed at one end of the top of the movable block 5 by a screw. A straight support plate 10 is installed at one end of the slanted support frame 6 by a screw. A placement plate 11 is placed between the two straight support plates 10. A fixed rod 21 is installed on the bottom surface of the straight support plate 10. A rotating handle is fixedly sleeved on the outside of the bidirectional threaded rod 4. The end face of the straight support plate 10 is in contact with the inner wall of the hanging mold 1. Placement slots are opened at both ends of the straight support plate 10. The placement plate 11 is placed inside the placement slots, which facilitates the rotation of the bidirectional threaded rod 4 by personnel, facilitates the support of the inner wall of the hanging mold 1, and facilitates the placement of the placement plate 11, ensuring the stability of the placement plate 11 after placement. A spring telescopic rod 22 is installed at the bottom of the fixed rod 21 by a screw. The bottom of the spring telescopic rod 22 is inside the closed plate 2.

[0035] The closed plate 2 is uniformly embedded with sliding connection limit blocks 7. The top of the limit block 7 is equipped with a movable plate 8 by screws. The longitudinal section of the limit block 7 is T-shaped. The end face of the movable plate 8 is provided with an inclined angle. The top surface of the limit plate 9 is in contact with the top surface of the closed plate 2, which facilitates the movement of the movable plate 8 and avoids the problem of the movable plate 8 falling off. At the same time, it can limit the top of the two closed plates 2 to prevent the two adjacent closed plates 2 from separating, thereby ensuring the support strength of the hanging mold 1. The limit plate 9 is installed at one end of the two movable plates 8 by screws.

[0036] Both ends of the lifting mold 1 are provided with sliding grooves 12. A slider 13 is slidably connected inside the sliding groove 12. A moving rod 14 is installed at one end of the slider 13 by screws. An insertion post 15 is slidably connected inside the moving rod 14. A clamping post 16 is installed at the bottom of the insertion post 15 by screws. A fixing screw 17 is threadedly connected inside the slider 13. The longitudinal sections of both the sliding groove 12 and the slider 13 are convex to prevent the slider 13 from falling out of the sliding groove 12. An installation groove is provided on the top surface of the sliding groove 12, and the fixing screw 17 is slidably connected inside the installation groove. One end face of the fixing screw 17 is in contact with the top surface of the lifting mold 1, which facilitates the fixing of the slider 13 and allows the slider 13 to be fixed in different positions. The clamping column 16 has an insertion groove at the position corresponding to the insertion column 15, and the outer diameter of the insertion column 15 is equal to the inner diameter of the insertion groove to ensure the stability of the insertion column 15. Both ends of the lifting mold 1 are connected to the connecting screw 18 by threads. The outer side of the connecting screw 18 is slidably connected to the mounting block 19. One end of the mounting block 19 is installed with the mounting column 20 by screws. The mounting column 20 is located inside the barrier plate 3.

[0037] A method of using a structural slab lowering formwork support device includes:

[0038] S1: Select different lengths and widths of hanging formwork 1 according to different construction sites, and select different specifications and quantities of enclosing plates 2 and barrier plates 3 according to different lengths and widths of hanging formwork 1;

[0039] S2: Place the hanging mold 1 in a suitable position;

[0040] S3: Move the clamping column 16 so that after the clamping column 16 comes into contact with the steel bar, it is fixed by the fixing screw 17;

[0041] S4: By rotating the bidirectional threaded rod 4, the straight support plate 10 comes into contact with the inner wall of the lifting mold 1.

[0042] During construction, after placing the suspended formwork 1 in a suitable position, personnel select different sizes of suspended formwork 1 according to the different construction areas required. Then, the suspended formwork 1 is moved to the appropriate position. Based on the different suspended formwork 1, different closing plates 2 and barrier plates 3 are selected and moved to the appropriate position. After the suspended formwork 1 is moved to the appropriate position, the closing plates 2 and barrier plates 3 are installed. After the installation of the closing plates 2 and barrier plates 3, the double-threaded rod 4 is rotated, driving the moving block 5 to move, which in turn drives the inclined support frame 6 to move, so that the straight support plate 10 contacts the inner wall of the suspended formwork 1. Finally, the placement plate 11 is placed inside the placement groove. This allows for support of the inner wall of the suspended formwork 1, ensuring its stability during use. Simultaneously, the spring telescopic rod 22 extends and moves into the interior of the closed plate 2, further guaranteeing its stability. This solves the problem of low connection efficiency caused by using nails to fix the suspended formwork 1 and closed plate 2, and reduces the labor intensity of workers. Furthermore, it supports the inner wall of the suspended formwork 1, preventing excessive pressure on its outer surface during subsequent concrete pouring, thus ensuring its stability and facilitating the construction of the lowered slab structure.

[0043] Before placing the formwork 1, personnel adjust the positions of the moving rod 14, the insertion column 15, and the clamping column 16 according to the position of the roof reinforcement. Two adjacent clamping columns 16 are moved to either side of the reinforcement. Then, the formwork 1 is placed on top of the reinforcement, with the two adjacent clamping columns 16 positioned at opposite ends of the reinforcement. It is then fixed with fixing screws 17, thus securing the formwork 1 and preventing it from swaying. During concrete pouring, the concrete gradually fills the clamping columns 16, allowing for pressure from all sides, further protecting the formwork. The above structure ensures the fixation of the suspended formwork 1, achieving multiple supports for the suspended formwork 1, improving its structural strength. Personnel can connect different suspended formwork 1s according to the size of the construction project. After aligning two suspended formwork 1s, personnel move the mounting column 20 inside one of the suspended formwork 1s, then fix the mounting block 19 using the connecting screw 18, thus fixing the two suspended formwork 1s. This facilitates application to different construction sites and expands the applicability of the support device. After concrete pouring, personnel rotate the bidirectional threaded rod 4 to disengage the straight support plate 10 from the inner wall of the suspended formwork 1, allowing for disassembly of the suspended formwork 1.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
