Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a corner template. Background Technology

[0002] Internal corner formwork is a specialized formwork used in building construction to create internal corners of walls, columns, and other structures, ensuring the quality of concrete forming at these corners. During construction, after the internal corner formwork is installed, a formwork assembly operation is required. This involves precisely combining the internal corner formwork with the adjacent planar formwork to form a complete formwork system. This ensures the accuracy of the structural dimensions and the integrity of the geometric shape at the internal corners during concrete pouring, effectively preventing quality defects such as grout leakage and misalignment, and guaranteeing sharp edges and straight lines.

[0003] During mold assembly, existing technologies mostly use bolts, clips, or pins to temporarily fix the internal corner template to the flat template. Once the flat template is aligned perfectly with the right-angled edge of the internal corner template, the connectors are then finally tightened to ensure the overall stability and structural robustness of the template system. However, due to the limitations of the connectors, the flat template has a limited range of movement during position adjustment, resulting in poor operational flexibility. Furthermore, the adjustment process increases the risk of damage to the flat template or internal corner template. In addition, the stress generated during the movement of the flat template can easily cause the connectors to loosen or undergo plastic deformation, severely affecting the subsequent tightening effect and the overall stability of the template system.

[0004] Therefore, there is an urgent need for a corner template to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a corner template that ensures the overall stability of the template system after the flat template and the corner template are closed, reduces the difficulty of the closing operation, and improves the closing speed.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A corner template is provided, comprising a template body with a right-angled triangular cross-section. The template body includes a side bevel and two side right-angled surfaces. The corner template also includes:

[0008] The mating part is movably disposed on the side slope along the extension direction of the side slope, and the mating part can be connected to the planar template;

[0009] The connecting component includes a first connector and a second connector. The first connector is vertically inserted into the template body and its position is adjustable in the vertical direction. One end of the second connector is hinged to the first connector and the other end is hinged to the mating part.

[0010] The driving component is detachably mounted on the template body and is connected to the first connector to drive the first connector to move vertically.

[0011] Optionally, the drive assembly includes a mounting base and a drive member. The mounting base is detachably mounted on the template body, and the drive member is rotatably mounted on the mounting base in the horizontal direction and hinged to the first connecting member, thereby driving the drive member to rotate and causing the first connecting member to move vertically.

[0012] Optionally, the drive assembly includes a mounting base and a drive component. The mounting base is detachably mounted on the template body, the drive component is coaxial with the first connector and rotatably mounted on the mounting base about its axial direction, and the drive component is threadedly connected to the first connector.

[0013] Optionally, the drive assembly includes a mounting base detachably disposed on the template body and a drive member disposed on the mounting base. The drive member includes an output shaft movable in the vertical direction, and the output shaft is connected to the first connector.

[0014] Optionally, the template body is provided with a fastener, and the drive component is provided with a connecting slot, which can be engaged or disengaged from the connecting slot.

[0015] Optionally, the connecting slot includes a first slot segment and a second slot segment that are connected to each other. The cross-sectional area of ​​the first slot segment is larger than that of the second slot segment, and the fastener can pass through the first slot segment and slide into the second slot segment via the first slot segment.

[0016] Optionally, the first connector is provided with a limiting hole, and the internal corner template also includes a limiting member that can be inserted into the limiting hole and contact the template body to limit the position of the first connector.

[0017] Optionally, a sliding hole extending along its extension direction is provided on the side inclined surface of the template body. The connecting component also includes a third connector, one end of which is hinged to the second connector, and the other end is inserted through the sliding hole and detachably connected to the mating part. The third connector slides in cooperation with the sliding hole.

[0018] Optionally, both ends of the side slope are provided with mating parts along its extension direction. Each mating part is connected to the first connecting part through several second connecting parts. The inside corner template also includes a guide component with adjustable extension length. One end of the guide component is connected to the mating part located at one end of the side slope, and the other end is connected to the mating part located at the other end of the side slope.

[0019] Optionally, the guiding assembly includes a first guide and a second guide that are slidably connected along its extension direction, the overlap length of the first guide and the second guide being adjustable, the first guide being connected to a docking member located at one end of the side slope, and the second guide being connected to a docking member located at the other end of the side slope.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention provides a corner formwork. When the first connecting member is moved vertically by a driving component, the end of the second connecting member connected to the first connecting member also moves accordingly. The second connecting member has a fixed length, so the end of the second connecting member connected to the butt joint also moves, causing the butt joint to move along the extension direction of the side slope. The butt joint connects to the flat formwork, allowing the flat formwork to move along with it during its movement. This adjusts the flatness between the flat formwork and the corner formwork, reducing misalignment and the risk of damage to both, and ensuring the overall stability of the formwork system after the flat and corner formwork are closed. Furthermore, flatness adjustment can be achieved simply by moving the first connecting member vertically, making operation convenient and eliminating the need for subsequent tightening, significantly improving the closing speed. The driving component is detachably connected to the formwork body; after the closing operation is completed, the driving component can be removed from the formwork body to prevent it from interfering with subsequent concrete pouring.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 5 As shown, this embodiment provides a corner template, which ensures the overall stability of the template system after the planar template and the corner template are closed, reduces the difficulty of the closing operation, and improves the closing speed.

[0038] See Figure 1 and Figure 2 The internal corner template includes a template body 1 with a right-angled triangular cross-section. The template body 1 includes a side inclined surface 11 and two side right-angled surfaces 12. The internal corner template also includes a connecting component 2, a connecting assembly 3, and a driving assembly 4. The connecting component 2 extends along the extension direction of the side inclined surface 11. Figure 1The X-direction (in the middle) is movably disposed on the side slope 11, and the mating part 2 can be connected to the planar template; the connecting assembly 3 includes a first connecting part 31 and a second connecting part 32, the first connecting part 31 being movably disposed on the side slope 11 along the vertical direction (in the X direction), and the mating part 2 being able to connect to the planar template; the connecting assembly 3 includes a first connecting part 31 and a second connecting part 3 Figure 1 The first connector 31 is inserted into the template body 1 in the Z direction and its position is adjustable in the vertical direction. One end of the second connector 32 is hinged to the first connector 31 and the other end is hinged to the docking member 2. The driving component 4 is detachably disposed on the template body 1 and is connected to the first connector 31 to drive the first connector 31 to move vertically.

[0039] In this embodiment, the corner template utilizes the driving assembly 4 to drive the first connecting member 31 vertically. Simultaneously, the end of the second connecting member 32 connected to the first connecting member 31 also moves. Since the length of the second connecting member 32 is fixed, the end of the second connecting member 32 connected to the connecting member 2 also moves, causing the connecting member 2 to move along the extension direction of the side slope 11. The connecting member 2 connects to the flat template, allowing the flat template to move along with it during its movement. This adjusts the flatness between the flat template and the corner template, reducing misalignment between them and lowering the risk of damage. It also ensures the overall stability of the template system after the flat template and corner template are closed. Furthermore, adjusting the flatness is achieved simply by driving the first connecting member 31 vertically, making operation convenient and eliminating the need for subsequent tightening, significantly improving the closing speed. The driving assembly 4 is detachably connected to the template body 1. After the closing operation is completed, the driving assembly 4 can be removed from the template body 1 to prevent it from affecting subsequent concrete pouring.

[0040] In this embodiment, see Figure 1 The template body 1 is a cylinder with a right-angled triangular cross-section. One end of the first connector 31 is located in the inner cavity of the cylinder, and the other end passes through the top surface and / or ground of the template body 1.

[0041] Specifically, see Figure 2 The mating component 2 includes a first surface 21, a second surface 22, and a third surface 23 arranged at an angle. The first surface 21 is attached to and slidably connected to the side inclined surface 11. The second surface 22 is parallel to the adjacent side right-angled surface 12. The third surface 23 is attached to the side of the flat template and connected to the flat template by bolts, clips, or pins. During the mold closing process, when the mating component 2 moves to the point where the second surface 22 is coplanar with the side right-angled surface 12, the first connecting component 31 can be controlled to stop moving, thus completing the adjustment of the flatness of the flat template and the internal corner template.

[0042] In an optional embodiment, see [link to relevant documentation] Figure 2 and Figure 4The driving component 4 includes a mounting base 41 and a driving member 42. The mounting base 41 is detachably mounted on the template body 1. The driving member 42 is rotatably mounted on the mounting base 41 in the horizontal direction and is hinged to the first connecting member 31. The driving member 42 is driven to rotate, and the driving member 42 drives the first connecting member 31 to move vertically. The mounting base 41 is fixed in position on the template body 1, so that the height of the connection between the driving member 42 and the mounting base 41 does not change when the driving member 42 rotates. The driving member 42 can rotate around its connection point with the mounting base 41, so that the height of the connection point between the driving member 42 and the first connecting member 31 will change during the rotation. The driving member 42 can drive the first connecting member 31 to move vertically, thereby realizing the adjustment of the position of the first connecting member 31.

[0043] In this embodiment, see Figure 1 , Figure 2 and Figure 4 The first connector 31 passes through the top surface of the template body 1, and the mounting base 41 is disposed on the top surface of the template body 1. The mounting base 41 is provided with a support member 411 extending vertically, and the support member 411 and the first connector 31 are aligned along a first direction (…). Figure 1 The drive unit 42 is arranged at intervals in the Y direction, and rotates around the second direction ( Figure 1 The drive member 42 (in the X direction) is rotatably mounted on the support member 411. Pressing down or pulling up the end of the drive member 42 along the first direction causes the drive member 42 to rotate relative to both the support member 411 and the first connecting member 31. Simultaneously, the height of the connection between the drive member 42 and the first connecting member 31 changes, causing the upper end of the first connecting member 31 to move up or down. The mating member 2 will move closer to or further away from the center of the side slope 11 along its extension direction, thereby adjusting the flatness of the planar template and the internal corner template. The horizontal direction includes the first direction and the second direction, and the first direction, the second direction, and the vertical direction are perpendicular to each other.

[0044] Specifically, see Figure 1 and Figure 4The driving component 42 includes two operating handles 421 and two transmission components 422. The two transmission components 422 are spaced apart along a second direction, and the two operating handles 421 are spaced apart along a first direction and are both connected to the transmission components 422. The two operating handles 421 and the two transmission components 422 form a planar frame structure with a rectangular cross-section. A first rotating shaft 412 is provided on the support component 411. The first rotating shaft 412 passes through the two transmission components 422 and the support component 411 along the second direction and is rotatably connected to both transmission components 422. The driving component 42 also includes a second rotating shaft 423 extending along the second direction. The two transmission components 422 are rotatably connected to the first connecting component 31 through the second rotating shaft 423. When the driving component 42 is driven to rotate, the operator raises or lowers the operating handles 421, which in turn drives the transmission components 422 to rotate relative to the support component 411.

[0045] For example, see Figure 1 Both the first connecting member 31 and the supporting member 411 are made of square steel pipe.

[0046] In another optional embodiment, the drive assembly 4 includes a mounting base 41 and a drive member 42. The mounting base 41 is detachably disposed on the template body 1. The drive member 42 is coaxial with the first connecting member 31 and rotatably disposed on the mounting base 41 about its axial direction. The drive member 42 is threadedly connected to the first connecting member 31. By driving the drive member 42 to rotate, the drive member 42 can drive the first connecting member 31 to move along its axial direction through the thread, thereby realizing the adjustment of the position of the first connecting member 31 in the vertical direction.

[0047] Specifically, the mounting base 41 is provided with a connecting hole, which is located directly above the first connector 31. The driving member 42 includes a screw part, and the diameter of the connecting hole is larger than the diameter of the screw part. The top of the first connector 31 is provided with a threaded groove that is threaded to the screw part. The screw part passes through the connecting hole and extends into the threaded groove. When the screw part is screwed, the screw part rotates relative to the connecting hole, and at the same time, the first connector 31 moves vertically.

[0048] Furthermore, the drive member 42 also includes an anti-detachment part disposed at the end of the screw portion. The anti-detachment part is located on the side of the mounting base 41 opposite to the first connector 31 and can contact the mounting base 41 to prevent the screw portion from disengaging from the connection hole.

[0049] For example, the drive component 42 is a bolt, with the screw portion being the shank of the bolt and the anti-loosening portion being the head of the bolt.

[0050] In another optional embodiment, the drive assembly 4 includes a mounting base 41 detachably disposed on the template body 1 and a drive member 42 disposed on the mounting base 41. The drive member 42 includes an output shaft movable in the vertical direction, and the output shaft is connected to the first connector 31. Vertical movement of the output shaft can drive the first connector 31 to move vertically, thereby realizing the adjustment of the position of the first connector 31 in the vertical direction.

[0051] For example, the drive unit 42 is a hydraulic cylinder, and the output shaft is the piston rod of the hydraulic cylinder.

[0052] Optionally, see Figure 1 and Figure 4 The template body 1 is provided with a fixing member 13, and the drive component 4 is provided with a connecting slot 413. The fixing member 13 can be inserted into or removed from the connecting slot 413. After the fixing member 13 is inserted into the connecting slot 413, it can constrain the position of the drive component 4 on the template body 1, so as to achieve a stable connection between the drive component 4 and the template body 1. After the fixing member 13 is removed from the connecting slot 413, the drive component 4 can be separated from the template body 1, thus completing the disassembly of the drive component 4 from the template body 1.

[0053] Specifically, see Figure 4 The connecting slot 413 is provided on the mounting base 41. Multiple fasteners 13 and multiple connecting slots 413 are provided, and the multiple fasteners 13 correspond one-to-one with the multiple connecting slots 413, which can increase the firmness and stability of the connection between the template body 1 and the drive component 4, and ensure the smooth operation of the mold closing operation.

[0054] For example, there are two fasteners 13 and two connecting slots 413, and the two fasteners 13 are symmetrically arranged on the template body 1.

[0055] For example, fastener 13 is a bolt.

[0056] In this embodiment, see Figure 1 The connecting slot 413 includes a first slot segment 4131 and a second slot segment 4132 that are connected. The cross-sectional area of ​​the first slot segment 4131 is larger than that of the second slot segment 4132. The fixing member 13 can pass through the first slot segment 4131 and slide into the second slot segment 4132 via the first slot segment 4131 to achieve the connection between the template body 1 and the drive component 4. When it is necessary to separate the template body 1 from the drive component 4, the fixing member 13 can be disengaged from the connecting slot 413 by disengaging from the second slot segment 4132 and sliding to the first slot segment 4131. The operation is convenient and quick, and easy to use on the construction site.

[0057] For example, see Figure 1 and Figure 4The fastener 13 includes a fixed head 131 and a fixed rod 132. The cross-sectional area of ​​the fixed head 131 is larger than the cross-sectional area of ​​the fixed rod 132. When the fastener 13 is inserted into the second groove 4132, the fixed rod 132 passes through the second groove 4132 and the fixed head 131 abuts against the mounting base 41.

[0058] The fastener 13 is set on the top surface of the template body 1. When installing the drive assembly 4, the fastener 13 is first passed vertically through the first groove 4131, and then the mounting base 41 is rotated so that the fastener 13 slides into the second groove 4132 through the first groove 4131, thereby fixing the mounting base 41 on the template body 1. When disassembling the drive assembly 4, the mounting base 41 is rotated so that the fastener 13 is disengaged from the second groove 4132.

[0059] Furthermore, bolts can be added between the mounting base 41 and the template body 1. That is, after the fixing member 13 is inserted into the second groove 4132, the bolts are allowed to pass through the mounting base 41 and be fastened to the template body 1 to prevent the mounting base 41 from rotating and detaching from the fixing member 13.

[0060] In some embodiments, the drive component 4 and the template body 1 can also be detachably connected directly by bolts. That is, when installing the drive component 4, the mounting base 41 is first placed on the template body 1, and then the bolts are passed through the connecting slot 413 and fastened to the template body 1.

[0061] Optionally, see Figure 2 The first connector 31 is provided with a limiting hole (not shown in the figure). The internal corner template also includes a limiting member 5. The limiting member 5 can be inserted into the limiting hole and contact the template body 1 to limit the position of the first connector 31, prevent the plane template from moving after the mold is closed, and ensure the effect of subsequent concrete pouring.

[0062] See Figure 2 When the second surface 22 of the mating part 2 is not coplanar with the side right angle surface 12, the limiting hole is located within the triangular space enclosed by the template body 1. When the first connecting part 31 needs to be moved, the limiting part 5 is removed from the limiting hole to avoid collision between the limiting hole and the template body 1. After the second surface 22 of the mating part 2 is coplanar with the side right angle surface 12, the mating part 2 stops moving. At this time, the limiting hole moves with the first connecting part 31 to the outside of the template body 1. Then the limiting part 5 is inserted into the limiting hole. The limiting part 5 contacts the top surface of the template body 1, so that the first connecting part 31 cannot move, ensuring the stability of the position of the mating part 2 and the planar template during the mold closing process.

[0063] Optionally, see Figure 2The template body 1 has a sliding hole 111 extending along its extension direction on its side inclined surface 11. The connecting component 3 also includes a third connecting member 33. One end of the third connecting member 33 is hinged to the second connecting member 32, and the other end passes through the sliding hole 111 and is detachably connected to the docking member 2. The third connecting member 33 slides in conjunction with the sliding hole 111. When the first connecting member 31 moves vertically, both ends of the second connecting member 32 will move and rotate. The third connecting member 33 can only slide within the sliding hole 111 under the action of the second connecting member 32, so that the docking member 2 can move along the extension direction of the side inclined surface 11 under the action of the third connecting member 33. When the first connecting member 31 moves vertically, the second connecting member 32 has a tendency to rotate as a whole. The hinge between the second connecting member 32 and the third connecting member 33 allows the second connecting member 32 to move along the extension direction of the sliding hole 111 without affecting the rotation of the second connecting member 32.

[0064] Specifically, see Figure 2 and Figure 5 The first connector 31 is provided with a third rotating shaft 311. One end of the second connector 32 is provided with a first ear hole (not shown in the figure), and the other end is provided with a second ear hole (not shown in the figure). The third rotating shaft 311 passes through the first ear hole and is rotatably connected to the first ear hole, thereby realizing the hinge connection between the first connector 31 and the second connector 32. The third connector 33 passes through the second ear hole and is rotatably connected to the second ear hole, thereby realizing the hinge connection between the third connector 33 and the second connector 32.

[0065] In this embodiment, see Figure 2 Multiple sliding holes 111, second connecting members 32, third connecting members 33, and third rotating shafts 311 are provided. The multiple sliding holes 111 are arranged at intervals along the vertical direction, and each of the multiple second connecting members 32, multiple third connecting members 33, and multiple third rotating shafts 311 corresponds one-to-one with a single sliding hole 111. This arrangement ensures that the amount of movement of each part of the mating member 2 along the vertical direction is the same. It also increases the driving force of the first connecting member 31 when it moves the mating member 2 through the second connecting members 32 and the third connecting members 33, thereby increasing the speed at which the mating member 2 moves the planar template.

[0066] In this embodiment, the internal corner template also includes a fastener, which passes through the docking member 2 and is threadedly connected to the other end of the third connecting member 33, thereby realizing a detachable connection between the third connecting member 33 and the docking member 2.

[0067] For example, see Figure 2 and Figure 5 The fasteners are bolts. The third connector 33 is connected to the docking part 2 at one end with a threaded hole 331. The docking part 2 is provided with a through hole 211. The bolt passes through the through hole 211 and is threaded into the threaded hole 331.

[0068] Optionally, see Figure 2 and Figure 3 The side slope 11 has connecting pieces 2 at both ends along its extension direction. Each connecting piece 2 is connected to a first connecting piece 31 via several second connecting pieces 32. The internal corner template also includes a guide component 6 with an adjustable extension length. One end of the guide component 6 is connected to the connecting piece 2 at one end of the side slope 11, and the other end is connected to the connecting piece 2 at the other end of the side slope 11. Driving the first connecting piece 31 to move vertically causes the first connecting piece 31 to move multiple second connecting pieces 32 simultaneously. The second connecting pieces 32 then move their corresponding connecting pieces 2. The distance between two connecting pieces 2 changes, and the extension length of the guide component 6 also changes accordingly. The guide component 6 increases the connection strength between the two connecting pieces 2 at both ends, ensuring the overall stability of the internal corner template structure. Moreover, the guide component 6 can further constrain the movement direction of the connecting pieces 2, ensuring the flatness of the flat template and the internal corner template after mold closing.

[0069] In this embodiment, see Figure 3 The guiding component 6 includes a first guide 61 and a second guide 62 slidably connected along its extension direction. The overlap length of the first guide 61 and the second guide 62 is adjustable. The first guide 61 is connected to a docking member 2 located at one end of the side slope 11, and the second guide 62 is connected to a docking member 2 located at the other end of the side slope 11. By sliding the first guide 61 and the second guide 62 relative to each other, the overlap length of the first guide 61 and the second guide 62 can be changed to accommodate the movement of the two docking members 2.

[0070] Specifically, when the two docking pieces 2 approach each other, the length of the guide component 6 decreases, and the overlap length of the first guide 61 and the second guide 62 increases; when the two docking pieces 2 move away from each other, the length of the guide component 6 increases, and the overlap length of the first guide 61 and the second guide 62 decreases.

[0071] For example, see Figure 3 The first guide 61 and the second guide 62 are coaxially arranged. The first guide 61 is a guide rod, and the second guide 62 is a guide tube. The guide rod is slidably inserted into the guide tube. The overlap length of the first guide 61 and the second guide 62 is the length of the guide rod inserted into the guide tube.

[0072] Further, see Figure 2 and Figure 3The first guide 61 is provided with a first socket 611, and the second guide 62 is provided with a second socket 621. The guide assembly 6 also includes a plug 63. When the docking member 2 moves to the point where the second surface 22 is coplanar with the side right angle surface 12, the first socket 611 and the second socket 621 are aligned, and the plug 63 can be inserted into the first socket 611 and the second socket 621 to restrict the position of the two docking members 2.
