Description

Technical Field

[0001] The present application relates to the technical field of non-disassembly formwork, and in particular to a connection mechanism for a non-disassembly formwork system for a wall. Background Art

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

[0003] Therefore, the market urgently needs a solution that can simultaneously realize the tensioning of the non-dismantling formwork on both sides of the wall and connect the non-dismantling formwork with the steel grid. Utility Model Content

[0004] In order to solve the above problems, the present application provides a connection mechanism for a wall non-disassembly formwork system, which has an ingenious design and a simple structure. By providing a clamping groove on the clamping member, the present application realizes a clamping connection between the clamping member and the transverse steel bar, thereby improving the installation efficiency of the clamping member. In addition, while achieving the pulling of the non-disassembly formwork on both sides of the steel grid, the non-disassembly formwork and the steel grid can be relatively fixed, which not only provides a lifting point for the overall lifting of the non-disassembly formwork and the steel grid, but also reduces the support requirements for the non-disassembly formwork during concrete pouring, and reduces the risk of displacement and deformation of the non-disassembly formwork. The technical solutions adopted in the present application are as follows:

[0005] A connection mechanism for a wall-free formwork system, comprising:

[0006] A clamping piece, the clamping piece is provided with two clamping grooves, the two clamping grooves are spaced apart along the length direction of the clamping piece, the opening width of the clamping groove is smaller than the diameter of the transverse steel bar in the wall steel reinforcement grid, and the clamping groove is suitable for clamping the transverse steel bar; a first anchor plate, the first anchor plate is connected to one end of the clamping piece; a second anchor plate, the second anchor plate is connected to the end of the clamping piece away from the first anchor plate, and a connecting screw is provided on the side of the second anchor plate away from the clamping piece; a third anchor plate, the third anchor plate is suitable for being screwed to the end of the connecting screw away from the second anchor plate.

[0007] By arranging a clamping groove on the clamping piece, a clamping connection between the clamping piece and the transverse steel bar is achieved, thereby improving the installation efficiency of the clamping piece. In addition, while realizing the pulling of the non-disassembly formwork on both sides of the steel mesh, the relative fixation of the non-disassembly formwork and the steel mesh is also achieved, thereby ensuring the overall stability of the non-disassembly formwork and the steel mesh, making it difficult to deform when the non-disassembly formwork and the steel mesh are lifted as a whole, and reducing the support requirements for the non-disassembly formwork when pouring concrete, and reducing the risk of offset and deformation of the non-disassembly formwork.

[0008] In some embodiments, a retaining tooth is provided on the groove wall at the opening of the clamping groove, and the teeth of the retaining tooth are inclined toward the inside of the clamping groove.

[0009] By providing the anti-retraction teeth, the secure connection between the clamping piece and the transverse steel bar can be ensured, and the risk of the transverse steel bar falling off from the clamping groove can be reduced.

[0010] In some embodiments, a guide flare is provided outside the opening of the clamping slot, and the opening size of the guide flare gradually increases in a direction away from the clamping slot.

[0011] By setting the guide flare, the guide flare plays a guiding role, guiding the transverse steel bars into the clamping groove, making it easy for the transverse steel bars to be clamped into the clamping groove, reducing the difficulty of aligning the transverse steel bars with the clamping groove. In other words, the guide flare is also a driving inclined surface.

[0012] In some embodiments, the first anchor plate and the second anchor plate are respectively welded to two ends of the clamping member.

[0013] In some embodiments, the clip is plate-shaped.

[0014] In some embodiments, stiffening ribs are provided at welding points between the clamping member and the first anchor plate and the second anchor plate.

[0015] By providing the stiffening ribs, the connection strength between the clamping piece and the anchor plate can be ensured, and the risk of damage occurring at the connection between the clamping piece and the anchor plate can be reduced.

[0016] In some embodiments, a notch is provided on a side of the clamping member facing away from the opening of the clamping slot, and the notch is distributed along the length direction of the clamping member.

[0017] By providing the notch, on the one hand, the weight of the clip can be reduced, making the clip lightweight; on the other hand, materials can be saved, thus reducing the cost of manufacturing the clip.

[0018] In some embodiments, the first anchor plate is provided with connection holes, and the connection holes are distributed on the edge of the first anchor plate.

[0019] By providing the connection hole, the riveting of the non-disassembly formwork and the first anchor plate can be facilitated, thereby improving the installation efficiency of the non-disassembly formwork.

[0020] In some embodiments, a side of the second anchor plate away from the clip is a rough surface.

[0021] By setting one side of the second anchor plate as a rough surface, the friction between the second anchor plate and the disassembly-free formwork can be increased, so that the second anchor plate shares more of the vertical force transmitted by the disassembly-free formwork, reducing the vertical force transmitted by the disassembly-free formwork borne by the connecting screw, and reducing the risk of damage to the disassembly-free formwork at the point where the connecting screw is inserted.

[0022] In some embodiments, the third anchor plate is provided with a plurality of through holes.

[0023] By arranging the through hole on the third anchor plate, on the one hand, the friction between the third anchor plate and the non-disassembly formwork is increased, and on the other hand, the weight of the third anchor plate can be reduced.

[0024] The present application provides a connection mechanism for a wall-free formwork system, which has at least one of the following beneficial effects:

[0025] 1. The present application provides a connection mechanism for a wall-free formwork system, which realizes a clamping connection between the clamping member and the transverse steel bar by setting a clamping groove on the clamping member, thereby improving the installation efficiency of the clamping member; in addition, while realizing the pulling of the free-disassembly formwork on both sides of the steel mesh, it can also realize the relative fixation of the free-disassembly formwork and the steel mesh, ensuring the overall stability of the free-disassembly formwork and the steel mesh, making it not easy to deform when the free-disassembly formwork and the steel mesh are hoisted as a whole, and can reduce the support requirements for the free-disassembly formwork when pouring concrete, and reduce the risk of offset and deformation of the free-disassembly formwork.

[0026] 2.

DETAILED DESCRIPTION

[0040] 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 those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0041] To simplify the drawings, only the parts relevant to this application are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0042] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0043] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] 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.

[0045] refer to Figures 1-4The present application provides a connection mechanism for a wall-free disassembly formwork system, comprising: a clip 1, a first anchor plate 4, a second anchor plate 5 and a third anchor plate 7; the clip 1 is provided with two clip grooves 2, and the two clip grooves 2 are spaced apart along the length direction of the clip 1, and the opening width of the clip groove 2 is smaller than the diameter of the transverse steel bar 3 in the wall steel bar grid, and the clip groove 2 is suitable for clipping the transverse steel bar 3; the first anchor plate 4 is connected to one end of the clip 1; the second anchor plate 5 is connected to the end of the clip 1 away from the first anchor plate 4, and the side of the second anchor plate 5 away from the clip 1 is provided with a connecting screw 6; the third anchor plate 7 is suitable for being screwed to the end of the connecting screw 6 away from the second anchor plate 5.

[0046] It is worth noting that the connection mechanism is used to achieve the pulling of the non-removal formwork 14 on both sides of the wall reinforcement grid, and the connection mechanism can be clamped on the transverse reinforcement 3 of the reinforcement grid. Specifically, the first anchor plate 4 is fixed with a non-removal formwork 14 on the side away from the second anchor plate 5, and a non-removal formwork 14 is also sandwiched between the second anchor plate 5 and the third anchor plate 7, and the reinforcement mesh is arranged between the two non-removal formworks 14. It is easy to understand that when the non-removal formwork 14 connected to the first anchor plate 4 is located on the inside of the wall (indoors), the non-removal formwork 14 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 14 sandwiched between the second anchor plate 5 and the third anchor plate 7 is located on the outer layer of the wall (outdoors), the non-removal formwork 14 can be an insulation board or a decorative panel for outdoor use.

[0047] It is easy to understand that when the connecting mechanism connected to the non-removal formwork 14 is clamped on the transverse reinforcement 3, it is equivalent to the transverse reinforcement 3 supporting the connecting mechanism and the non-removal formwork 14. The clamping member 1 in the connecting mechanism can only be clamped on the transverse reinforcement 3 of the reinforcement mesh. The clamping member 1 is equivalent to being placed on the transverse reinforcement 3, which can prevent the connecting mechanism and the non-removal formwork 14 from moving downward relative to the reinforcement mesh; if the clamping member 1 is clamped on the vertical reinforcement of the reinforcement mesh, it is also necessary to take measures to prevent the connecting mechanism and the non-removal formwork 14 from moving downward relative to the reinforcement mesh. It is understandable that the opening width of the clamping groove 2 is smaller than the diameter of the transverse reinforcement 3, so as to ensure that the transverse reinforcement 3 will not easily fall out after being clamped into the clamping groove 2. The internal space of the clamping groove 2 can accommodate the transverse reinforcement 3. It is best that the internal space of the clamping groove 2 is compatible with the transverse reinforcement 3 to minimize the gap between the two. When installing the clip 1, it is necessary to place the clip 1 on (overlay) the transverse steel bar 3, align the opening of the clip groove 2 with the transverse steel bar 3, and then hammer the clip 1 downward to make the transverse steel bar 3 fit into the clip groove 2.

[0048] It is worth noting that the reference Figure 1 、 Figure 2In one embodiment, a retaining tooth 8 is provided on the wall of the slot at the opening of the engaging slot 2, with the teeth of the retaining tooth 8 tilted toward the interior of the engaging slot 2. The provision of the retaining tooth 8 ensures a secure engagement between the engaging member 1 and the transverse reinforcement 3, reducing the risk of the transverse reinforcement 3 falling out of the engaging slot 2.

[0049] refer to Figure 2 In one embodiment, a guide flare 9 is provided outside the opening of the clamping groove 2. The opening size of the guide flare 9 gradually increases in the direction away from the clamping groove 2. The guide flare 9 serves as a guide, guiding the transverse reinforcement 3 into the clamping groove 2, making it easier for the transverse reinforcement 3 to be clamped into the clamping groove 2, and reducing the difficulty of aligning the transverse reinforcement 3 with the clamping groove 2. In other words, the guide flare 9 is also a driving inclined surface. When the transverse reinforcement 3 is located in the guide flare 9, when it is perpendicular to the clamping member 1, the guide flare 9 will drive the transverse reinforcement 3 into the clamping groove 2.

[0050] In one embodiment, the first anchor plate 4 and the second anchor plate 5 are respectively welded to both ends of the clamping member 1. In other embodiments, the first anchor plate 4 and the second anchor plate 5 can also be screwed to the clamping member 1.

[0051] It is understandable that the clamping member 1 can be in the shape of a round rod or a plate. The plate shape is preferred because it facilitates the molding of the clamping groove 2 and saves material for making the clamping member 1.

[0052] refer to Figure 1 、 Figure 3 、 Figure 4 In one embodiment, stiffening ribs 10 are provided at the welds between the connector 1 and the first and second anchor plates 4 and 5. The provision of stiffening ribs 10 ensures the connection strength between the connector 1 and the anchor plates, reducing the risk of damage at the connection between the connector 1 and the anchor plates.

[0053] refer to Figure 1 In one embodiment, a notch 11 is provided on the side of the clip 1 facing away from the opening of the clip slot 2. The notch 11 is distributed along the length of the clip 1, that is, the notch 11 is elongated. The provision of the notch 11 can reduce the weight of the clip 1, making it lightweight, and can also save material and reduce the cost of manufacturing the clip 1.

[0054] refer to Figure 1 、 Figure 3 、 Figure 4In one embodiment, the first anchor plate 4 is provided with connection holes 12, which are distributed along the edge of the first anchor plate 4. The provision of the connection holes 12 allows the first anchor plate 4 to be connected to the non-removal formwork 14 using connectors such as blind rivets or self-tapping screws inserted through the connection holes 12, thereby improving the installation efficiency of the non-removal formwork 14. By arranging the connection holes 12 along the edge of the first anchor plate 4, the non-removal formwork 14 and the first anchor plate 4 are evenly stressed, reducing the risk of damage to the non-removal formwork 14 at the connection with the first anchor plate 4.

[0055] In one embodiment, the side of the second anchor plate 5 away from the clamping member 1 is roughened. By providing a roughened side of the second anchor plate 5, the friction between the second anchor plate 5 and the non-removal formwork 14 can be increased, so that the second anchor plate 5 shares more of the vertical force transmitted by the non-removal formwork 14, reducing the vertical force transmitted by the non-removal formwork 14 borne by the connecting screw 6, and reducing the risk of damage to the non-removal formwork 14 at the point where the connecting screw 6 is inserted.

[0056] It is worth noting that the reference Figure 1 、 Figure 4 In one embodiment, the third anchor plate 7 is provided with a plurality of through holes 13. By providing the through holes 13 on the third anchor plate 7, the friction between the third anchor plate 7 and the non-removal formwork 14 is increased on the one hand, and the weight of the third anchor plate 7 is reduced on the other hand.

[0057] 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 noted 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 considered as the scope of protection of the present application.
