Description

Technical Field

[0001] This utility model relates to the field of building formwork, and more specifically, to an early stripping system for cast-in-place floor slab formwork. Background Technology

[0002] With the rapid development of the construction industry, cast-in-place concrete structures are playing an increasingly important role in modern construction. Formwork engineering has become a major construction tool, and roof slab formwork systems, especially those for high-rise buildings, are developing rapidly. Early stripping formwork systems are a type of formwork system designed to allow for the early removal of floor slab formwork. They offer advantages such as saving formwork, labor, and materials, and accelerating project progress. Their application in construction is becoming increasingly widespread. Specifically, during formwork construction, the method of integral casting of walls and slabs is adopted. For example, the casting of floor slabs requires the prefabrication of keel beams and formwork supported by supporting columns and early stripping support devices before casting.

[0003] The utility model patent with authorization announcement number CN 222045023 U discloses an early stripping system for cast-in-place floor slab formwork, including multiple sets of aluminum frame formwork, anti-loosening early stripping support devices, and independent steel supports (3); multiple independent steel supports (3) are arranged in a square array to support the next floor, and an anti-loosening early stripping support device (2) is installed above each independent steel support (3); the four corners of the aluminum frame formwork (1) are supported on an anti-loosening early stripping support device (2) respectively, forming a planar matrix frame formwork; the planar matrix frame formwork is provided with edge adjustable supports (4) at the edge position; the inner two corners of the cantilevered aluminum frame formwork (1) are supported on the anti-loosening early stripping support devices (2) installed above the independent steel supports (3) at the edge of the planar matrix frame formwork; the outer two corners are supported on the edge adjustable supports (4). This solves the support problem of the edge cantilever structure, and at the same time, it is equipped with a protective device to prevent support failure and prevent premature stripping or grout leakage.

[0004] The aforementioned disclosed structure uses a relatively complex template structure, which is not conducive to combined installation and positioning. Furthermore, it lacks a template frame for separate installation of combined templates, making it impossible to support and position them individually. It is also not conducive to disassembling the templates individually for early dismantling, which affects subsequent maintenance. It has poor adaptability and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an early removal system for cast-in-place floor slab formwork. By setting connecting grooves in the formwork frame, the combined formwork can be installed in separate parts. Combined with the limiting plate, the bottom can be limited to ensure the flatness of the top. Furthermore, by installing support threaded rods through the first and second support cylinders, the combined installation can be reinforced from the bottom, which is conducive to molding and casting, and also facilitates separate disassembly for early removal operations. It is also beneficial for maintenance, highly adaptable, and easy to install and use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An early stripping system for cast-in-place floor slab formwork includes a formwork frame. The formwork frame has a connecting groove inside. A first support cylinder is fixedly connected to the lower surface of the formwork frame, located around the sides of the connecting groove. A combined formwork is fixedly installed inside the connecting groove. The upper surface of the combined formwork is aligned with the upper surface of the formwork frame. A clearance groove is provided on the lower surface of the combined formwork. A limiting plate is fixedly connected to the lower edge of the combined formwork, and the limiting plate is tightly connected to the lower surface of the formwork frame. A second support cylinder is fixedly connected to the middle position inside the clearance groove. Both the second and first support cylinders have threaded holes inside. Support threaded rods are threaded into the threaded holes and spaced apart on the lower surface of the formwork frame.

[0008] Furthermore, an adjusting rod is fixedly connected to one end surface of the supporting threaded rod, and the adjusting rod is located on the side where the first supporting cylinder slides against the second supporting cylinder.

[0009] Furthermore, an extended threaded cylinder is threadedly installed at one end of the supporting threaded rod, and a tightening plate is fixedly connected to one end of the extended threaded cylinder.

[0010] Furthermore, the top clamping plate is located directly below the template frame and is flush with each other. The adjusting rod is installed by supporting the threaded rod, and the top clamping plate is connected by the extended threaded cylinder. It can be threadedly installed and positioned, which is conducive to adjusting the length of the thread and supporting and reinforcing from the bottom. It is convenient to pour the floor slab from the upper layer, which is precise, efficient and highly adaptable.

[0011] Furthermore, a tensioning screw is installed in the internal thread of the threaded hole, and the tensioning screw is positioned and connected to one end of the first support cylinder.

[0012] Furthermore, a tensioning plate is mounted on one end of the tensioning screw, and the tensioning screw is rotatably connected to both ends of the tensioning plate.

[0013] Furthermore, the tensioning screws are located at the edge of the template frame and positioned on the lower surface of the template frame. By installing the tensioning screws and tensioning plates through the threaded holes, adjacent template frames can be tightened and fixed, ensuring the tightness of the combined position and improving the stability of the support pouring.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution sets a connecting groove through the template frame, thereby installing the combined template separately. Combined with the limiting plate, it can limit the bottom and ensure the flatness of the top. Furthermore, the first and second support cylinders are used to install the support thread rod, which can be combined and reinforced from the bottom, which is conducive to molding and casting. It is also convenient to disassemble separately for early disassembly, which is conducive to maintenance. It has high adaptability and is convenient to install and use.

[0016] (2) By installing the adjusting rod through the support threaded rod and connecting the top plate with the extended threaded cylinder, the threaded installation and positioning can be achieved, which is conducive to adjusting the length of the threaded rod and supporting and reinforcing from the bottom. It is convenient to pour the floor slab from the upper layer, which is precise, efficient and highly adaptable.

[0017] (3) By installing tension screws and tension plates through threaded holes, adjacent template frames can be tightened and fixed to ensure the tightness of the combined position and improve the stability of the support pouring. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 4 and Figure 5 A cast-in-place floor slab formwork early removal system includes a formwork frame 1. The formwork frame 1 has a connecting groove 11 inside. A first support cylinder 12 is fixedly connected to the lower surface of the formwork frame 1, located on the four sides of the connecting groove 11. A combined formwork 13 is fixedly installed inside the connecting groove 11. Connecting the combined formwork 13 to the connecting groove 11 allows it to be combined and positioned with the formwork frame 1, forming a flat surface that supports the pouring of the floor slab from the top after positioning, facilitating installation and use. The upper surface of the combined formwork 13 is aligned with the upper surface of the formwork frame 1. The lower surface of the combined formwork 13 has an avoidance groove 14. A limiting plate 15 is fixedly connected to the lower edge of the combined formwork 13. By setting the limiting plate 15, it can be pressed against the lower surface of the formwork frame 1, providing limiting support and ensuring the combined formwork 13 and the formwork frame 1 are properly positioned. Alignment is ensured to prevent upward protrusion and interference, resulting in precise stability. The limiting plate 15 is tightly connected to the lower surface of the template frame 1. A second support cylinder 16 is fixedly connected to the middle position inside the clearance groove 14. Both the second support cylinder 16 and the first support cylinder 12 have threaded holes 17 inside. Support threaded rods 2 are installed inside the threaded holes 17. The support threaded rods 2 are distributed at intervals on the lower surface of the template frame 1. After connecting the template frame 1 and the combined template 13, an integrated template structure can be formed. Then, the support threaded rods 2 are installed from the bottom, which can provide support and reinforcement from the bottom, facilitating casting from the top. After the concrete floor slab has solidified, the combined template 13 can be disassembled and separated for early dismantling operations. The template frame 1 can provide auxiliary support, improve subsequent stability, and allow for curing of the concrete floor slab from the connection groove 11 position. This facilitates operation and has high adaptability.

[0027] Please see Figure 1 and Figure 2 An adjusting rod 23 is fixedly connected to one end of the supporting threaded rod 2. The adjusting rod 23 is located on the side where the first supporting cylinder 12 slides against the second supporting cylinder 16. An extended threaded cylinder 21 is threadedly installed on one end of the supporting threaded rod 2. A top clamping plate 22 is fixedly connected to one end of the extended threaded cylinder 21. The top clamping plate 22 is located directly below the template frame 1 and is flush with each other. By installing the adjusting rod on the supporting threaded rod and connecting the top clamping plate with the extended threaded cylinder, the threaded installation and positioning can be achieved. This facilitates the adjustment of the threaded length for bottom support and reinforcement, making it convenient to pour the floor slab from the upper layer. It is precise, efficient, and highly adaptable. By rotating the supporting threaded rod 2 through the adjusting rod 23, it can be threaded into the threaded hole 17, thereby connecting to the first supporting cylinder 12 and the second supporting cylinder 16 respectively, which can provide auxiliary support. Then, by rotating the extended threaded cylinder 21 from the bottom, the length can be adjusted to ensure that the top clamping plate 22 is pressed tightly against the lower ground level, which can provide support and reinforcement, improve safety and stability, and facilitate adjustment and use.

[0028] Please see Figure 2 and Figure 3 A tensioning screw 24 is installed in the internal thread of the threaded hole 17. The tensioning screw 24 is positioned and connected to one end of the first support cylinder 12. A tensioning plate 25 is installed at one end of the tensioning screw 24. The tensioning screw 24 is rotatably connected to both ends of the tensioning plate 25. The tensioning screw 24 is located at the edge of the template frame 1 and positioned on the lower surface of the template frame 1. By installing the tensioning screw and tensioning plate through the threaded hole, the adjacent template frames can be tightened and fixed to ensure the tightness of the combined position and improve the stability of the support pouring.
