Description

Technical Field

[0001] This utility model specifically relates to a U-shaped steel formwork that is easy to disassemble. Background Technology

[0002] The crash barriers on both sides of urban underground road projects are usually designed with longitudinal drainage channels. These channels are typically poured together with the crash barriers, which requires the use of U-shaped steel formwork during the pouring process. However, ordinary U-shaped steel formwork needs to be pried off from both sides and the bottom after the concrete is poured, making the demolding process very cumbersome and easily damaging the completed concrete. Furthermore, most crash barriers are currently made of undecorated concrete, so damage to the surface will seriously affect the appearance quality of the crash barriers.

[0003] Therefore, it is necessary to invent a U-shaped steel formwork that is easy to dismantle in order to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a U-shaped steel formwork that is easy to dismantle, which can ensure the appearance quality of concrete structures.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped steel template that is easy to disassemble, comprising a U-shaped steel template body, wherein adjustment components are installed on both sides of the inner wall of the U-shaped steel template body, and connection components and connection holes are respectively provided at both ends of the U-shaped steel template body;

[0008] The adjustment assembly includes two sets of telescopic screws, which are respectively installed on both sides of the inner wall of the U-shaped steel template body and are symmetrically arranged. Both sets of telescopic screws are equipped with positive and negative thread sleeves at their ends, and the two sets of telescopic screws are respectively installed at both ends of the positive and negative thread sleeves.

[0009] The connecting components are disposed at both ends of the top extension plate of the U-shaped steel formwork body. The extension plate is disposed on both sides of the top of the U-shaped steel formwork body and extends inward. The connecting components are installed on the same side of the ends of the extension plates. The connecting components include a fixing plate, which is fixed to the top edge of the extension plate and extends therein. A plug is fixed to the bottom of one side of the fixing plate. A cavity is provided on one side of the plug. A locking component is installed in the cavity. The plug matches the connecting hole. The cavity is disposed below the connecting hole.

[0010] The connection hole is located at the other end of the extension plate.

[0011] Preferably, a limiting frame extends from the cavity opening, and the locking assembly is installed inside the cavity. It includes a locking protrusion, and a limiting strip extends outward from the bottom of the locking protrusion. The limiting strip matches the limiting frame, and a compression spring is installed between the bottom of the locking protrusion and the bottom of the cavity. The compression spring is fixedly installed.

[0012] Preferably, the locking protrusion has beveled surfaces on both the top and bottom sides and is symmetrically arranged. The locking protrusion is installed as a whole at the bottom of the connecting hole, and the overall length of the locking assembly meets the requirements for docking with the connecting hole, that is, each group of U-shaped steel template bodies is interconnected.

[0013] Preferably, the adjustment components are provided in multiple sets and are evenly spaced on the inner wall of the U-shaped steel formwork body. Each set of telescopic screws has a reinforcing base installed at its bottom, and the reinforcing base is fixed on the inner wall of the U-shaped steel formwork body.

[0014] Preferably, the bottom dimension of the reinforcing base is larger than the dimension of the telescopic screw, the internal thread direction of the positive and negative thread sleeve is opposite, that is, the moving directions of the telescopic screws on both sides are opposite, and the outer wall of the positive and negative thread sleeve is provided with multiple evenly spaced anti-slip textures.

[0015] Preferably, the fixing plate has beveled surfaces on all four sides.

[0016] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0017] 1. When dismantling the formwork after use, this utility model does not require prying or knocking the formwork. The rotation of the positive and negative threaded sleeves can cause the telescopic screws on both sides to retract inward. When the outer walls on both sides of the formwork separate from the concrete surface, the U-shaped steel formwork can be directly removed, reducing the possibility of damage to the concrete on both sides.

[0018] 2. In this utility model, after the insert block is inserted into the connecting hole, the locking protrusion automatically engages in the hole under the action of the compression spring. The limiting strip and the limiting frame work together to prevent it from falling off, thus achieving quick connection. It can handle construction situations of different lengths.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The U-shaped steel formwork shown includes a U-shaped steel formwork body 1, with adjustment components 2 installed on both sides of the inner wall of the U-shaped steel formwork body 1, and connection components 3 and connection holes 4 respectively provided at both ends of the U-shaped steel formwork body 1.

[0029] Reference Figure 3 The adjusting component 2 includes two sets of telescopic screws 21. The two sets of telescopic screws 21 are respectively installed on both sides of the inner wall of the U-shaped steel template body 1 and are symmetrically arranged. The ends of the two sets of telescopic screws 21 are jointly installed with positive and negative thread sleeves 22. The two sets of telescopic screws 21 are respectively installed at both ends of the positive and negative thread sleeves 22.

[0030] Reference Figure 4-5 The connecting component 3 is set at both ends of the top extension plate 11 of the U-shaped steel formwork body 1. The extension plate 11 is set on both sides of the top of the U-shaped steel formwork body 1 and extends inward. The connecting component 3 is installed on the same side of the end of the extension plate 11. It includes a fixing plate 31, which is fixed to the top edge of the extension plate 11 and extends. A plug 32 is fixed at the bottom of one side of the fixing plate 31. A cavity 33 is provided on one side of the plug 32. A locking component 34 is installed in the cavity 33. The plug 32 matches the connecting hole 4. The cavity 33 is set below the connecting hole 4.

[0031] Specifically, the connection hole 4 is located at the other end of the extension plate 11.

[0032] In this embodiment, rotating the positive and negative threaded sleeve 22 drives the two sets of telescopic screws 21 to extend and retract synchronously. The anti-slip texture 24 on the sleeve enhances friction during operation and facilitates manual adjustment. After adjustment to the desired width, the reinforced base 23 provides support stability.

[0033] Specifically, a limiting frame 35 extends from the opening of the cavity 33, and a locking assembly 34 is installed inside the cavity 33. The locking assembly includes a locking protrusion 341, and a limiting strip 342 extends from the bottom of the locking protrusion 341 to the surrounding area. The limiting strip 342 matches the limiting frame 35, and a compression spring 343 is installed between the bottom of the locking protrusion 341 and the bottom of the cavity 33. The compression spring 343 is fixedly installed.

[0034] Specifically, the locking protrusion 341 has beveled surfaces on both the top and bottom sides and is symmetrically arranged. The locking protrusion 341 is installed at the bottom of the connecting hole 4, and the overall length of the locking component 34 meets the requirements for docking with the connecting hole 4, that is, each group of U-shaped steel template bodies 1 is connected to each other.

[0035] In this embodiment, the insert block 32 of one template is inserted into the connecting hole 4 of another template. When the insert block 32 is pressed down, the inclined surface of the locking protrusion 341 is compressed, the compression spring 343 contracts, and the protrusion temporarily retracts into the cavity 33. When the insert block is fully inserted, the compression spring 343 rebounds, the locking protrusion 341 pops out and locks against the inner wall of the connecting hole 4, achieving automatic locking. The limiting strip 342 cooperates with the limiting frame 35 to prevent the protrusion from falling out.

[0036] Reference Figure 1-2 The adjustment components 2 are provided in multiple sets and are evenly spaced on the inner wall of the U-shaped steel formwork body 1. Each set of telescopic screws 21 has a reinforcing base 23 installed at the bottom, and the reinforcing base 23 is fixed on the inner wall of the U-shaped steel formwork body 1.

[0037] Reference Figure 3 The bottom dimension of the reinforced base 23 is larger than the dimension of the telescopic screw 21. The internal thread direction of the positive and negative thread sleeve 22 is opposite, that is, the moving direction of the telescopic screws 21 on both sides is opposite. The outer wall of the positive and negative thread sleeve 22 is provided with multiple evenly spaced anti-slip textures 24.

[0038] Specifically, the four sides of the fixing plate 31 are all beveled.

[0039] In this embodiment, to release the lock, manually press the locking protrusion 341 to retract it into the cavity 33, then pull out the insert 32. The elasticity of the compression spring 343 ensures smooth locking or unlocking. Rotating the forward and reverse threaded sleeve 22 in the opposite direction retracts the telescopic screw 21, separating the inner wall of the template from the concrete.

[0040] In this embodiment, the positive and negative threaded sleeve 22 synchronously adjusts the telescopic screws 21 on both sides to ensure that the template width changes symmetrically and avoids skewing. The reinforced base 23 can distribute the force on the telescopic screws 21, enhance the structural stability, and prevent deformation during pouring.

[0041] In this embodiment, the locking protrusion 341 in the locking component 34 automatically locks upon insertion, requiring no additional tools; pressing unlocks it, resulting in high demolding efficiency. Multiple sets of evenly distributed adjustment points in the adjustment components 2 ensure uniform stress on the inner wall of the template, preventing localized deformation. This template can be quickly disassembled and reassembled after demolding, reducing labor costs.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
