Description

Technical Field

[0001] The present application relates to the technical field of non-disassembly formwork, and further to a connection mechanism capable of clamping steel bars. Background Art

[0002] At present, the wall non-disassembly formwork system is vigorously promoted and widely used due to its advantages of saving labor, no need to disassemble the formwork, and saving construction period. The wall non-disassembly formwork system has gradually replaced the formwork system. After the current wall non-disassembly formwork system is installed on both sides of the steel mesh of the wall, in order to fix the non-disassembly formwork and avoid excessive relative displacement between the non-disassembly formwork and the steel mesh, some support parts need to be set outside the non-disassembly formwork to support the non-disassembly formwork. This process still requires a lot of manpower and material resources. In addition, since only the non-disassembly formwork on both sides of the steel mesh is pulled, and the non-disassembly formwork is not connected and fixed to the steel mesh, after the non-disassembly formwork is installed, especially during the pouring of concrete, the non-disassembly formwork will be offset, affecting the formwork accuracy and wall forming quality. In addition, since the non-disassembly formwork is not connected and fixed to the steel mesh, it is difficult to realize the overall lifting of the non-disassembly formwork and the steel mesh after the assembly of the non-disassembly formwork and the steel mesh is completed in the prefabrication factory.

[0003] Therefore, the market is in urgent need of a solution that can simultaneously realize the tensioning of the non-dismantling formwork on both sides of the wall and realize the connection between the non-dismantling formwork and the steel grid. Utility Model Content

[0004] In order to solve the above problems, the present application provides a connection mechanism capable of clamping steel bars, which has an ingenious design and a simple structure. The present application can realize the connection between the non-dismantling formwork and the steel grid by setting a clamping component while realizing the tension of the non-dismantling formwork on both sides of the steel grid. This not only provides a lifting point for the overall lifting of the non-dismantling formwork and the steel grid, but also reduces the support requirements for the non-dismantling formwork when pouring concrete, and reduces the risk of deviation and deformation of the non-dismantling formwork, thereby improving the molding quality after wall pouring. The technical solutions adopted in the present application are as follows:

[0005] A connecting mechanism capable of clamping steel bars, comprising:

[0006] A tension screw; a first anchor plate, the first anchor plate is suitable for being screwed to one end of the tension screw; a second anchor plate, a connecting screw is provided on one side of the second anchor plate, the second anchor plate is suitable for being screwed to the other end of the tension screw; a third anchor plate, the third anchor plate is suitable for being connected to an end of the connecting screw away from the second anchor plate; a clamping assembly, the clamping assembly is provided with a first through hole, the tension screw is suitable for being penetrated through the first through hole, and the clamping assembly is used to clamp the steel bar to fix the tension screw to the steel mesh.

[0007] This application can realize the pulling of the non-removal formwork on both sides of the steel mesh, and at the same time, realize the connection between the non-removal formwork and the steel mesh by setting up clamping components. This not only provides a solid lifting point for the overall lifting of the non-removal formwork and the steel mesh, but also reduces the support requirements for the non-removal formwork when pouring concrete, and reduces the risk of offset and deformation of the non-removal formwork, thereby improving the molding quality after wall pouring.

[0008] In some embodiments, the clamping assembly includes a U-shaped member, a first rod and a first bolt, the first through hole is a waist-shaped hole and is provided in the U-shaped member, the U-shaped member is further provided with a second through hole and a third through hole, the first rod is suitable for being provided in the second through hole, and the first bolt is suitable for being provided in the third through hole and being screwed to the U-shaped member;

[0009] When in use, the steel bars of the steel mesh are passed through the tension screw and the first rod. One end of the first bolt is exposed from the U-shaped part, and the other end abuts against the tension screw. By screwing the first bolt, the distance between the tension screw and the first rod can be adjusted to clamp the steel bars.

[0010] By setting the first through hole as a waist-shaped hole, the tension screw can move in the first through hole in a direction perpendicular to the tension screw. When the first bolt is screwed, the tension screw is pushed by the first bolt, so that the distance between the tension screw and the first rod is getting closer and closer, thereby clamping the steel bar between the tension screw and the first rod.

[0011] In some embodiments, the third through hole is a threaded hole, and the first bolt is suitable for being threaded into the third through hole.

[0012] By setting the third through hole as a threaded hole, the first bolt can be directly screwed to the third through hole without separately setting a nut.

[0013] In some embodiments, a first nut is welded at the third through hole of the U-shaped member, and the first bolt is suitable for being screwed to the first nut.

[0014] By providing the first nut, the process of forming a screw thread in the third through hole can be saved, and the requirement on the thickness of the U-shaped part can be reduced.

[0015] In some embodiments, the clamping assembly includes a clamping member and a second nut, the clamping member includes a pressing portion and a protrusion fixed to the pressing portion, the first through hole is provided in the pressing portion, and the second nut is threadedly connected to the tension screw;

[0016] When in use, the steel bars of the steel mesh are passed between the two clamping assemblies or between the clamping member and the first anchor plate or between the clamping member and the second anchor plate. The position of the second nut on the tension screw can be adjusted by screwing the second nut to clamp the steel bars and enable the protrusion to limit the lateral displacement of the steel bars.

[0017] The clamping member including the pressing part and the protruding part has a simple structure and is easy to produce and process. By screwing the second nut, the pressing part can be pressed against the steel bar, and the protruding part can limit the lateral movement of the steel bar to prevent the steel bar from falling out of the pressing part.

[0018] In some embodiments, the protrusion is conical, and the tip of the protrusion is far away from the pressing portion. By setting the protrusion to be conical, the greater the thrust of the second nut on the pressing portion, the stronger the limiting effect of the protrusion on the lateral movement of the steel bar, and the better the clamping effect of the clamp on the steel bar.

[0019] In some embodiments, the protrusion is wedge-shaped, and the tip of the protrusion is away from the pressing portion. By setting the protrusion to be wedge-shaped, the contact area between the protrusion and the steel bar can be increased, the wrapping effect of the clamping member on the steel bar can be improved, the risk of the steel bar slipping relative to the clamping member can be reduced, and the relative displacement of the non-disassembly formwork and the steel bar grid when hoisting the integral body composed of the non-disassembly formwork and the steel bar grid can be reduced.

[0020] In some embodiments, a third nut is welded on one side adjacent to the first anchor plate and the second anchor plate, and the tension screw is screwed to the first anchor plate and the second anchor plate respectively through the third nut, and the overall thickness of the third nut and the first anchor plate, and the overall thickness of the third nut and the second anchor plate are both adapted to the thickness of the protective layer of the steel mesh.

[0021] By controlling the overall thickness of the third nut and the first anchor plate, the distance between the non-disassembly formwork and the steel bars can be controlled, without the need to provide additional spacers between the non-disassembly formwork and the steel bars.

[0022] In some embodiments, the first anchor plate is provided with rivet holes, and the rivet holes are distributed at the edge of the first anchor plate. By providing the rivet holes, the rivet connection between the non-disassembly formwork and the first anchor plate can be facilitated, thereby improving the installation efficiency of the non-disassembly formwork.

[0023] In some embodiments, the side of the second anchor plate away from the first anchor plate is a rough surface. By setting one side of the second anchor plate as a rough surface, the friction between the second anchor plate and the non-removal formwork can be increased, so that the second anchor plate shares more of the vertical force of the non-removal formwork, reducing the load on the connecting screw.

[0024] The present application provides a connection mechanism capable of clamping steel bars, which has at least one of the following beneficial effects:

[0025] 1. The present application provides a connection mechanism capable of clamping steel bars. The application can realize the pulling of the non-disassembly formwork on both sides of the steel mesh frame, and at the same time, realize the connection between the non-disassembly formwork and the steel mesh frame by setting a clamping assembly. This not only provides a solid lifting point for the overall lifting of the non-disassembly formwork and the steel mesh frame, but also reduces the support requirements for the non-disassembly formwork when pouring concrete, and reduces the risk of displacement and deformation of the non-disassembly formwork, thereby improving the molding quality of the wall after pouring.

[0026] 2. The present application provides a connection mechanism capable of clamping a steel bar, wherein the first through hole is set as a waist-shaped hole, so that the tension screw can move in the first through hole in a direction perpendicular to the tension screw. When the first bolt is screwed, the tension screw is pushed by the first bolt, so that the distance between the tension screw and the first rod is getting closer and closer, thereby clamping the steel bar between the tension screw and the first rod.

The present application provides a connection mechanism capable of clamping steel bars, including a clamping member having a pressing portion and a protruding portion, which has a simple structure and is easy to produce and process.

[0030] 6. The present application provides a connection mechanism capable of clamping steel bars. By setting the protrusion to a cone, the thrust force of the second nut on the pressing part is greater, and the limiting effect of the protrusion on the lateral displacement of the steel bar is stronger, thereby improving the clamping effect of the clamping member on the steel bar.

By setting the protrusion to a wedge shape, the contact area between the protrusion and the steel bar can be increased, the wrapping effect of the clamping part on the steel bar can be improved, the risk of the steel bar slipping relative to the clamping part can be reduced, and the relative displacement of the non-disassembly formwork and the steel bar mesh when hoisting the whole composed of the non-disassembly formwork and the steel bar mesh.

[0032] 8. The present application provides a connection mechanism capable of clamping steel bars, which can control the distance between the non-disassembly formwork and the steel bars by controlling the overall thickness of the third nut and the first anchor plate, without the need to set additional pads between the non-disassembly formwork and the steel bars.

DETAILED DESCRIPTION

[0049] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0050] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0051] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0052] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] refer to Figure 1-Figure 3The present application provides a connection mechanism capable of clamping steel bars, comprising a tension screw 1, a first anchor plate 2, a second anchor plate 3, a third anchor plate 5 and a clamping assembly; the first anchor plate 2 is suitable for being screwed to one end of the tension screw 1, and the second anchor plate 3 is suitable for being screwed to the other end of the tension screw 1; a connecting screw 4 is provided on the side of the second anchor plate 3 away from the first anchor plate 2, and the third anchor plate 5 is suitable for being connected to the end of the connecting screw 4 away from the second anchor plate 3; the clamping assembly comprises a U-shaped member 8, a first rod member 9 and a first bolt 10, the U-shaped member 8 is provided with a first through hole 6, a second through hole and a third through hole, the first through hole 6 is a waist-shaped hole, the tension screw 1 is suitable for being penetrated in the first through hole 6, the first rod member 9 is suitable for being penetrated in the second through hole, the third through hole is a threaded hole, and the first bolt 10 is suitable for being screwed to the third through hole.

[0055] It is worth noting that the connection mechanism is used to realize the pulling of the non-removal formwork 17 on both sides of the steel mesh, and the connection mechanism can be fixed on the steel bars 7 of the steel mesh. Specifically, the non-removal formwork 17 is fixed on the side of the first anchor plate 2 away from the second anchor plate 3, and the non-removal formwork 17 is also sandwiched between the second anchor plate 3 and the third anchor plate 5, and the steel mesh is arranged between the two non-removal formworks 17. It is easy to understand that when the non-removal formwork 17 connected to the first anchor plate 2 is located on the inner side of the wall (indoors), the non-removal formwork 17 can be a calcium silicate board, a cement fiber board or a wooden formwork, or a decorative panel for indoor use. When the non-removal formwork 17 sandwiched between the second anchor plate 3 and the third anchor plate 5 is located on the outer layer of the wall (outdoors), the non-removal formwork 17 can be an insulation board or a decorative panel for outdoor use.

[0056] It is understandable that the first rod 9 can only be installed after the U-shaped member 8 is buckled on a steel bar 7 or buckled on the intersection of the steel bars 7, so that an extrusion space is formed between the tension screw 1 and the first rod 9. By screwing the first bolt 10, the first bolt 10 pushes the tension screw 1, so that the tension screw 1 moves in a direction perpendicular to the tension screw 1, and then the distance between the tension screw 1 and the first rod 9 becomes closer and closer, that is, the extrusion space formed between the tension screw 1 and the first rod 9 becomes smaller and smaller, and then the steel bar 7 is clamped between the tension screw 1 and the first rod 9. Obviously, the tighter the tension screw 1 and the first rod 9 clamp the steel bar 7, the less likely it is that the non-disassembly formwork 17 and the steel bar 7 grid bracket will have relative displacement, which not only ensures the molding quality after the wall is poured, but also improves the integrity of the non-disassembly formwork 17 and the steel bar grid, and is convenient for lifting with the tension screw 1 as the lifting point.

[0057] In the above embodiment, the third through hole is a threaded hole, which enables the first bolt 10 to be directly screwed to the third through hole without the need to provide a nut separately. In other embodiments, a first nut 11 may be welded to the third through hole of the U-shaped member 8, and the connection between the U-shaped member 8 and the first bolt 10 is achieved by screwing the first nut 11 and the first bolt 10. By providing the first nut 11, the process of providing a thread in the third through hole can be saved. In addition, since there is no need to provide a thread in the third through hole, the thickness requirement of the U-shaped member 8 can be reduced.

[0058] refer to Figure 4-Figure 9 The present application provides a connection mechanism capable of clamping steel bars, comprising a tension screw 1, a first anchor plate 2, a second anchor plate 3, a third anchor plate 5 and a clamping assembly; the first anchor plate 2 is suitable for being screwed to one end of the tension screw 1, and the second anchor plate 3 is suitable for being screwed to the other end of the tension screw 1; a connecting screw 4 is provided on the side of the second anchor plate 3 away from the first anchor plate 2, and the third anchor plate 5 is suitable for being connected to the end of the connecting screw 4 away from the second anchor plate 3; the clamping assembly comprises a clamping member and a second nut 12, the clamping member comprises a pressing portion 13 and a protruding portion 14 fixed to the pressing portion 13, the pressing portion 13 is provided with a first through hole 6, the tension screw 1 is suitable for being penetrated into the first through hole 6, and the second nut 12 is screwed to the tension screw 1.

[0059] It is understandable that the steel bar 7 can be clamped between two clamping members, or between one clamping member and the first anchor plate 2 or the second anchor plate 3. The position of the second nut 12 on the tension screw 1 can be adjusted by screwing the second nut 12, so that the clamping member exerts a greater and greater thrust on the steel bar 7, thereby clamping the steel bar 7 more tightly. In this embodiment, the pressing portion 13 is used to push the steel bar 7, thereby clamping the steel bar 7, and the protrusion 14 can limit the lateral displacement of the steel bar 7, preventing the steel bar 7 from escaping from the pressing portion 13.

[0060] In this embodiment, the protrusion 14 may be rod-shaped, or may be cone-shaped or wedge-shaped, as long as it can limit the lateral displacement of the steel bar 7. Figure 4-Figure 6 When the protrusion 14 is conical, the tip of the protrusion 14 is far away from the pressing portion 13. By setting the protrusion 14 to be conical, the greater the thrust of the second nut 12 on the pressing portion 13, the stronger the limiting effect of the protrusion 14 on the lateral movement of the steel bar 7 is, thereby improving the clamping effect of the clamp on the steel bar 7. Figure 7-Figure 9 When the raised portion 14 is wedge-shaped, the tip of the raised portion 14 is away from the pressing portion 13. By setting the raised portion 14 to be wedge-shaped, the contact area between the raised portion 14 and the steel bar 7 can be increased, thereby improving the wrapping effect of the clamping member on the steel bar 7, reducing the risk of the steel bar 7 slipping relative to the clamping member, and reducing the relative displacement of the non-disassembly formwork 17 and the steel bar grid when hoisting the non-disassembly formwork 17 and the steel bar grid as a whole.

[0061] refer to Figure 1 , Figure 4 , Figure 7 In some embodiments, a third nut 15 is welded on one side adjacent to the first anchor plate 2 and the second anchor plate 3, and the tension screw 1 is screwed to the first anchor plate 2 and the second anchor plate 3 respectively through the third nut 15. The overall thickness of the third nut 15 and the first anchor plate 2, and the overall thickness of the third nut 15 and the second anchor plate 3 are both adapted to the thickness of the protective layer of the steel bar 7 grid. It is understandable that the third nut 15 may not be provided, but threaded holes may be directly opened on the first anchor plate 2 and the second anchor plate 3, but there is a disadvantage in doing so: in order to ensure the screw connection strength, a large number of thread turns are required, which will increase the thickness of the first anchor plate 2 and the second anchor plate 3. It is also worth noting that by controlling the overall thickness of the third nut 15 and the first anchor plate 2, the distance between the non-disassembly formwork 17 and the steel bar 7 can be controlled, and there is no need to set a separate pad between the non-disassembly formwork 17 and the steel bar 7.

[0062] refer to Figure 1 , Figure 4 , Figure 7 In some embodiments, the first anchor plate 2 is provided with rivet holes 16. Preferably, the rivet holes 16 are distributed at the edge of the first anchor plate 2. It can be understood that by providing the rivet holes 16, the riveting of the non-removal template 17 and the first anchor plate 2 can be facilitated, thereby improving the installation efficiency of the non-removal template 17. In other embodiments, the side of the first anchor plate 2 away from the second anchor plate 3 can be screwed to the fourth anchor plate, and the non-removal template 17 can be sandwiched between the first anchor plate 2 and the fourth anchor plate.

[0063] In some embodiments, the side of the second anchor plate 3 away from the first anchor plate 2 is a rough surface. It is easy to understand that by setting one side of the second anchor plate 3 as a rough surface, the friction between the second anchor plate 3 and the non-removal formwork 17 can be increased, so that the second anchor plate 3 shares more of the vertical force of the non-removal formwork 17, and the load-bearing burden of the connecting screw 4 is reduced.

[0064] refer to Fig.10 In some embodiments, the connecting screw 4 and the third anchor plate 5 are integral, that is, the connecting screw 4 is fixed to the third anchor plate 5, and the two are inseparable, while the connecting screw 4 and the second anchor plate 3 are screwed. Fig.11 In other embodiments, the connecting screw 4 and the second anchor plate 3 are an integral whole, the connecting screw 4 is fixed to the second anchor plate 3, and the two are inseparable, while the connecting screw 4 and the third anchor plate 5 are screwed.

[0065] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
