Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a wooden formwork early removal system device. Background Technology

[0002] The early formwork stripping device is the core component of the early stripping system, typically consisting of support rods, early stripping heads, and connecting components. Its working principle is to remove part of the formwork and supports early after concrete pouring, while retaining some of the rear-dismantled uprights to continue supporting the concrete structure, thus accelerating formwork turnover and reducing material usage. The early stripping head uses adjustable mechanical structures (such as bolts, rotating heads, or top supports) to achieve partial formwork removal while retaining supports, allowing for earlier turnover of formwork materials before the concrete strength fully reaches the standard demolding strength, improving construction efficiency. For example, common early stripping head designs include rotatable formwork supports that connect to the formwork via slots and detach from the formwork during removal through rotation or lowering.

[0003] In the assembly of the early stripping system for wooden formwork, the early stripping device is usually connected with components such as support poles, wooden I-beams or square steel pipe keels to form a temporary support system. During construction, the early stripping head is installed on the top of the support pole, and the formwork is fixed by limit bolts or rotating structure. After the concrete reaches early strength, the formwork is removed by adjusting the early stripping head, while the support pole is retained to continue bearing the load.

[0004] Early stripping devices, during construction, often suffer from issues such as corrosion of limiting bolts or rotating structures due to environmental exposure, and plastic deformation under repeated loads, leading to disassembly difficulties. For example, in patent application number 202220712261.6, a formwork early stripping device and system, while threaded connections and slot designs improve support stability, the threaded rods and rotating heads are prone to rust in humid construction environments and may deform under the impact of concrete pouring, causing rotational jamming or bolt seizing, requiring additional tools for disassembly, thus increasing construction complexity. Similarly, patent application number 202220904591.5, a green building aluminum formwork early stripping structure, also points out that traditional early stripping heads rely on bolt fastening, which easily loses precision due to wear or corrosion after long-term use, affecting the safety of the support system. These problems not only reduce construction efficiency but may also lead to concrete cracks or structural deformation due to support failure. While existing technologies attempt to alleviate the above problems through material improvements (such as the use of aluminum alloys) or structural optimization, they have not fundamentally solved the issues of device durability and disassembly reliability under harsh operating conditions. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model embodiment is to provide a wooden formwork early removal system device, which aims to solve the problem that the early removal device is difficult to dismantle due to the corrosion of the limit bolts or rotating structure exposed to the environment during construction, and the plastic deformation under repeated loads.

[0007] (II) Technical Solution

[0008] Specifically: A timber formwork early-stripping system device includes a connector and two locking components. The connector is used to clamp the uprights and place the main joists. The two locking components are detachably mounted on the connector to lock the connector to the uprights. The connector includes two symmetrically distributed side connectors, which are rotatably assembled on one side via a rotating connection structure. The two side connectors are clamped to the outside of the uprights via the rotating connection structure, and the two locking components lock the two side connectors while simultaneously suspending the rotating connection structure for protection. Each locking component includes a locking rod with a threaded post at its end for locking the locking component to the two side connectors. The two side connectors are clamped to the outside of the upright through a rotating connection structure. Two locking parts are locked to both sides of the two side connectors by threaded posts. Since the threaded posts are located at the ends of the locking rods, they can be protected inside the connectors and locking parts, avoiding direct exposure and corrosion. This design uses two locking parts to lock the two side connectors while simultaneously suspending and protecting the rotating connection structure. This suspension disperses the force, preventing direct force from acting on the rotating connection structure and eliminating the possibility of plastic deformation under repeated loads. Disassembly is easy and efficient.

[0009] The technical solution of this application will be further described below:

[0010] In one embodiment, the side connector includes an arc-shaped clamping plate. The arc-shaped clamping plates of the two side connectors are symmetrically distributed to form a clamping cavity for clamping the upright. A sliding plate is integrally fixed on the top of the arc-shaped clamping plate, and the sliding plate is perpendicular to the arc-shaped clamping plate.

[0011] Furthermore, a baffle is fixed to the end of the slide away from the arc-shaped clamping plate, and the baffle is perpendicular to the slide; the slide inside the baffle is used to place the main keel.

[0012] Furthermore, the side connector also includes two limiting plates, which are integrally fixed on the sides of the arc-shaped clamping plate and distributed along the sides of the arc-shaped clamping plate.

[0013] Furthermore, the limiting plate has a limiting hole for the locking rod to pass through; a limiting flange is fixed at the end of the limiting plate away from the arc-shaped clamping plate; the limiting plate and the limiting flange are fixed as a single unit.

[0014] In one embodiment, the rotating connection structure includes a positioning shaft, which is rotatably assembled in a mounting groove, the mounting groove being formed on a side connector; a rotating plate is fixed on the main body of the positioning shaft, and a horizontal plate is fixed at the end of the rotating plate away from the positioning shaft.

[0015] Furthermore, the horizontal plate is movably inserted into the positioning block, and the positioning block is fixed on the other side connector; the positioning block has an insertion cavity to accommodate the movable insertion of the horizontal plate; a limit block is fixed at the end of the horizontal plate to prevent the horizontal plate from falling off the positioning block.

[0016] In one embodiment, the locking component further includes a U-shaped clamping plate and a locking cylinder. The U-shaped clamping plate is used to clamp onto the two side connectors. The U-shaped clamping plate has through holes for the locking rod to be inserted. The locking cylinder is fixed on the side wall of the U-shaped clamping plate and is used to receive the threaded post and lock it with the threaded post.

[0017] Furthermore, the locking rod includes an insert post for movably inserting into an insert hole; a threaded post is fixed to one end of the insert post, and a nut is fixed to the end of the insert post away from the threaded post.

[0018] Therefore, in the early stripping system of wooden formwork, the arc-shaped clamping plates of the two side connectors are symmetrically distributed to form a clamping cavity. The clamping cavity is held outside the upright by a rotating connection structure as the rotation point. The locking element is secured to the limiting plates of the two side connectors by a U-shaped clamping plate. The locking rod passes through the inserting post into the U-shaped clamping plate and the two limiting plates, and then through the threaded post into the locking cylinder for threaded locking. This completes the locking of the two locking elements to the two sides of the two side connectors by the threaded post. Because the threaded post is at the locking position... At the end of the rod, the threaded post can be protected by entering the connector and locking parts, avoiding direct exposure and thus preventing corrosion. During the locking of the two side connectors by the two locking parts, the two limiting plates move closer to each other, and the horizontal plate moves and inserts in the interlocking cavity on the positioning block. This completes the protection of the positioning shaft on the rotating connection structure by suspending it. This suspending protection of the rotating connection structure disperses the force, preventing the force from acting directly on the rotating connection structure and eliminating the possibility of plastic deformation under repeated loads. Disassembly is easy and efficient.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] In the early stripping system for wooden formwork, two side connectors are clamped to the outside of the uprights via a rotating connection structure. Two locking components are locked to both sides of the two side connectors via threaded posts. Since the threaded posts are located at the ends of the locking rods, they can be protected by entering the connectors and locking components, avoiding direct exposure and thus reducing corrosion. This system locks the two side connectors with two locking components while simultaneously protecting the rotating connection structure by suspending it. This suspending protection disperses the force, preventing the force from acting directly on the rotating connection structure and eliminating the possibility of plastic deformation under repeated loads. Disassembly is easy and efficient.

[0022] The built-in threads not only prevent corrosion, but also, due to the protection of the outer structure, prevent bending deformation under impact or load; while the overhead design of the rotating shaft not only prevents it from being deformed by pressure, but also indirectly reduces the risk of damage and corrosion to the threaded parts because it no longer requires frequent violent disassembly; these two functions, originally designed to solve different problems, reinforce each other and jointly improve the durability of the overall device.

[0023] By suspending the rotating shaft and distributing the force to a more stable support structure, the entire device exhibits unexpected stability when subjected to impact loads. This not only eliminates the risk of plastic deformation but also allows for easy disassembly without the need for additional tools, significantly improving disassembly efficiency. This is an excellent performance of "easy to install and disassemble and long life" that is difficult to achieve in conventional designs. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. The specific implementation of the present utility model will be described in detail below with reference to specific embodiments.

[0036] In one embodiment of this utility model, such as Figures 1-4 As shown: A timber formwork early dismantling system device includes a connector 1 and two locking parts 2. The connector 1 is used to clamp the uprights and place the main joists; the two locking parts 2 are detachably attached to the connector 1 and used to lock the connector 1 to the uprights.

[0037] The connector 1 includes two symmetrically distributed side connectors 11. The two side connectors 11 are rotatably assembled on one side through a rotating connection structure 18. The two side connectors 11 are clamped to the outside of the upright through the rotating connection structure 18 as the rotation point. The two side connectors 11 are locked by two locking pieces 2 while the rotating connection structure 18 is suspended for protection.

[0038] Therefore, in the early stripping system of wooden formwork, the two side connectors 11 are clamped to the outside of the upright through the rotating connection structure 18 as the rotation point, and the two locking pieces 2 lock the two side connectors 11 while the rotating connection structure 18 is suspended for protection. The suspension of the rotating connection structure 18 disperses the force, avoids the force from acting directly on the rotating connection structure 18, and eliminates the possibility of plastic deformation under repeated loads. Disassembly is easy and efficient.

[0039] Locking member 2 includes locking rod 23, and locking rod 23 is provided with threaded post 231 at its end. Threaded post 231 is used to lock locking member 2 onto two side connectors 11.

[0040] Therefore, the two locking parts 2 are locked to the two side connecting parts 11 by the threaded post 231. Since the threaded post 231 is located at the end of the locking rod 23, the threaded post 231 can be protected inside the connecting part 1 and the locking part 2, avoiding direct exposure and thus reducing corrosion by reducing exposure.

[0041] In summary, regarding the difficulties in disassembly of early-release devices caused by corrosion of limit bolts or rotating structures due to environmental exposure during construction, and plastic deformation under repeated loads, this application can achieve the following:

[0042] In the early dismantling system of wooden formwork, two side connectors 11 are clamped to the outside of the upright through a rotating connection structure 18. Two locking parts 2 are locked to both sides of the two side connectors 11 by threaded posts 231. Since the threaded posts 231 are located at the end of the locking rod 23, they can be protected inside the connectors 1 and locking parts 2, avoiding direct exposure and thus reducing corrosion. The two side connectors 11 are locked by the two locking parts 2, while the rotating connection structure 18 is suspended for protection. The suspension of the rotating connection structure 18 disperses the force, preventing the force from acting directly on the rotating connection structure 18 and eliminating the possibility of plastic deformation under repeated loads. Dismantling is easy and efficient.

[0043] In another embodiment of this utility model, such as Figures 1-4 As shown: The side connector 11 includes an arc-shaped clamping plate 14. The arc-shaped clamping plates 14 of the two side connectors 11 are symmetrically distributed to form a clamping cavity, which is used to clamp the upright. A sliding plate 12 is integrally fixed on the top of the arc-shaped clamping plate 14. The sliding plate 12 is perpendicular to the arc-shaped clamping plate 14.

[0044] Furthermore, such as Figure 4 As shown: A baffle 13 is fixed at one end of the slide plate 12 away from the arc-shaped clamping plate 14. The baffle 13 is perpendicular to the slide plate 12. The slide plate 12 inside the baffle 13 is used to place the main keel.

[0045] like Figure 4 As shown: The side connector 11 also includes a limiting plate 15. There are two limiting plates 15, which are integrally fixed on the sides of the arc-shaped clamping plate 14. The limiting plates 15 are distributed along the sides of the arc-shaped clamping plate 14.

[0046] like Figure 4 and Figure 5As shown: The limiting plate 15 has a limiting hole 16 for the locking rod 23 to pass through; the end of the limiting plate 15 away from the arc-shaped clamping plate 14 is fixed with a limiting flange 17; the limiting plate 15 and the limiting flange 17 are fixed as a whole.

[0047] In another embodiment of this utility model, such as Figure 5 and Figure 6 As shown: The rotating connection structure 18 includes a positioning shaft 181, which is rotatably assembled in a mounting groove 183. The mounting groove 183 is formed on a side connector 11 (specifically, the mounting groove 183 is formed on a limiting protrusion 17 of a side connector 11). A rotating plate 182 is fixed on the main body of the positioning shaft 181, and a horizontal plate 184 is fixed at the end of the rotating plate 182 away from the positioning shaft 181.

[0048] Furthermore, such as Figure 5 and Figure 6 As shown: The horizontal plate 184 is movably inserted into the positioning block 185, and the positioning block 185 is fixed on the other side connector 11 (specifically, the positioning block 185 is fixed on the limiting protrusion 17 of the limiting plate 15 of the other side connector 11); the positioning block 185 has an insertion cavity to cooperate with the horizontal plate 184 to movably insert; the horizontal plate 184 has a limiting block 186 fixed at its end, and the limiting block 186 is used to prevent the horizontal plate 184 from falling off the positioning block 185.

[0049] In another embodiment of this utility model, such as Figures 1-3 , Figure 7 and Figure 8 As shown: The locking component 2 also includes a U-shaped clamping plate 22 and a locking cylinder 21. The U-shaped clamping plate 22 is used to clamp onto the two side connectors 11 (the U-shaped clamping plate 22 is used to clamp onto the limiting plates 15 of the two side connectors 11). The U-shaped clamping plate 22 has an insertion hole 24 for the locking rod 23 to be inserted movably. The locking cylinder 21 is fixed on the side wall of the U-shaped clamping plate 22. The locking cylinder 21 is used to receive the threaded post 231 and is threadedly locked with the threaded post 231.

[0050] Furthermore, such as Figures 1-3 , Figure 7 and Figure 8 As shown: The locking rod 23 includes an insert post 232, which is used to be movably inserted into the insert hole 24; a threaded post 231 is fixed to one end of the insert post 232, and a nut 233 is fixed to the end of the insert post 232 away from the threaded post 231.

[0051] Therefore, in the early stripping system of wooden formwork, the arc-shaped clamping plates 14 of the two side connectors 11 are symmetrically distributed to form a clamping cavity. The clamping cavity is clamped to the outside of the upright by the rotating connection structure 18 as the rotation point. The locking member 2 is clamped on the limiting plate 15 of the two side connectors 11 by the U-shaped clamping plate 22. The locking rod 23 is inserted into the U-shaped clamping plate 22 and the two limiting plates 15 by the through-pin 232, and then threaded into the locking cylinder 21 by the threaded pin 231 for threaded locking. The two locking members 2 are locked to the two sides of the two side connectors 11 by the threaded pin 231. At the end of the locking rod 23, the threaded post 231 can be protected inside the connector 1 and the locking member 2, avoiding direct exposure and thus reducing corrosion. During the process of locking the two side connectors 11 by the two locking members 2, the two limiting plates 15 move closer to each other, and the horizontal plate 184 moves and inserts into the insertion cavity on the positioning block 185. This completes the protection of the positioning shaft 181 on the rotating connection structure 18 by suspending it. The suspension protection of the rotating connection structure 18 disperses the force, preventing the force from acting directly on the rotating connection structure 18 and eliminating the possibility of plastic deformation under repeated loads. Disassembly is easy and efficient.

[0052] In another embodiment of this utility model, the arc-shaped clamping plates 14 of the two side connectors 11 form a clamping cavity in a symmetrical manner, and are firmly clamped to the outside of the upright with the rotating connection structure 18 as the axis; the U-shaped clamping plate 22 is first clamped on the limiting plate 15 of the two side connectors 11, and then the inserting post at the front end of the locking rod 23 passes through the U-shaped clamping plate 22 and the limiting plate 15, and the threaded post 231 at the end is screwed into the locking cylinder 21 to complete the threaded locking.

[0053] This locking process incorporates multiple synergistic effects: First, the threaded connection is internalized, and the threaded post 231, after being tightened, completely enters the interior of the connector 1 and the locking member 2, forming a structural anti-rust protection that isolates it from the humid air of the construction site, fundamentally reducing the difficulty of disassembly caused by thread corrosion; Second, when the two locking members 2 are locked simultaneously, the limiting plates 15 on both sides move closer to each other, while the horizontal plate 184 slides in the insertion cavity of the positioning block 185; This linkage mechanism cleverly suspends the positioning shaft 181 in the rotating connection structure 18, removing it from the direct force-bearing area; The force transmission path is thus changed, and the load is distributed to the surrounding rigid components such as the limiting plate and the horizontal plate, thereby effectively protecting the fragile rotating shaft.

[0054] At the same time, the built-in threads not only prevent corrosion, but also avoid bending deformation under impact or load because they are protected by the outer structure; while the overhead design of the rotating shaft 181 not only prevents it from being deformed by pressure, but also indirectly reduces the risk of damage and corrosion to the threaded parts because it no longer requires frequent violent disassembly; these two functions, which were originally designed to solve different problems, reinforce each other and jointly improve the durability of the overall device.

[0055] By using an overhead rotating shaft 181 to distribute the force to a more stable support structure, the entire device exhibits unexpected stability when subjected to impact loads. This not only eliminates the risk of plastic deformation but also allows for easy disassembly without the need for additional tools, significantly improving disassembly efficiency. This is an excellent performance of "easy to install and disassemble and long life" that is difficult to achieve in conventional designs.

[0056] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Although embodiments of this utility model have been shown and described in the description of this utility model, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
