Description

Technical Field

[0001] This utility model relates to the field of water-stop curtain technology, and in particular to a positioning template for interlocking columns of a foundation pit water-stop curtain. Background Technology

[0002] In the construction of underground and water conservancy projects, water-stop curtains are widely used as a key construction technology. Interlocking columns in water-stop curtains are a structural component used to stabilize the water-stop curtain structure. They are typically connected to the water-stop curtain at a certain angle, with a steel reinforcement cage inserted diagonally into the water-stop curtain, and concrete is poured to integrate the interlocking columns and the water-stop curtain into a single unit.

[0003] However, despite the crucial role of interlocking columns in practical applications of water-stop curtains, current construction techniques still have some shortcomings. During construction, the use of positioning templates is essential to ensuring the accuracy and quality of the interlocking columns. However, existing positioning templates often have limitations, making it difficult to effectively and flexibly adjust the angles of the interlocking columns and water-stop curtains. Due to the complexity and diversity of construction environments, different projects have varying requirements for the angles of the interlocking columns and water-stop curtains. The fixed structure and limited adjustment range of existing positioning templates make it difficult for construction workers to precisely control the angles of the interlocking columns and water-stop curtains, thus increasing construction difficulty, reducing construction efficiency, and potentially leading to problems such as poor water-stopping effect and structural instability. Utility Model Content

[0004] In view of this, the embodiments of this utility model provide a positioning template for the interlocking columns of the foundation pit water-stop curtain, which solves the technical problem in the prior art that the template structure is fixed and it is not easy to adjust the applicable angle.

[0005] This utility model provides a positioning template for interlocking columns of a foundation pit water-stop curtain, used to position the interlocking columns that obliquely penetrate the water-stop curtain, including:

[0006] Two templates are used; the first template is perpendicularly attached to the water-stop curtain, and the second template is inclined to the first template and perpendicular to the interlocking column.

[0007] A connecting structure is provided between two templates. The connecting structure includes a support tube, a first end cap, a second end cap, a first geared disc, a second geared disc, and a handle. The support tube is connected to the first template, and the handle is connected to the second template. The first and second end caps are respectively connected to the two ends of the support tube. The first geared disc and the second end cap are connected to one side of the support tube. The handle is connected to the second geared disc and rotatably connected relative to the second end cap. The second geared disc and the first geared disc are coaxial and meshable. After the first and second geared discs mesh, the handle and the second end cap become integrated, thus restricting the rotation of the handle relative to the support tube.

[0008] A locking element is disposed between the first template and the second template to restrict the relative movement of the first template and the second template, so that the two templates remain in a stable position after adjustment.

[0009] Furthermore, a rotating rod is connected to the axis of the second gear disk, and a mating plate is connected to the end of the rotating rod, the mating plate being connected to the handle.

[0010] Furthermore, a movable hole is provided through the axis of the second end cap, and the rotating rod can rotate and slide with respect to the movable hole.

[0011] Furthermore, the support tube has receiving holes extending through both ends, and both the first toothed disc and the second toothed disc are received within the receiving holes.

[0012] Furthermore, the connection structure also includes an elastic element located within the receiving hole, with one end of the elastic element connected to the first end cap and the other end abutting against the second toothed disc.

[0013] Furthermore, the locking component includes a locking rod, a locking frame, and a locking cylinder. The locking rod is rotatably connected to one side of the first template, and the locking frame is rotatably connected to one side of the second template. The locking rod passes through the locking frame, and the locking cylinder is pressed against the locking frame, thereby restricting the movement of the locking rod relative to the locking frame.

[0014] Furthermore, a groove is provided on the side of the second template, and the lock frame rotates within the groove. The width of the groove is greater than that of the lock frame, so that the inner wall of the lock frame is flush with the groove.

[0015] Furthermore, both ends of the support tube are provided with hexagonal countersunk holes, and the first end cap and the second end cap are provided with hexagonal protrusions facing the end of the support tube, with the hexagonal protrusions corresponding to the hexagonal countersunk holes.

[0016] Furthermore, a spring seat is provided in the middle of the hexagonal protrusion on the first end cap, and one end of the elastic element is connected to the spring seat.

[0017] Furthermore, both the first template and the second template have through holes in their middle sections, and the diameter of these through holes is larger than the diameter of the interlocking posts.

[0018] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The positioning template of the interlocking column of the foundation pit water-stop curtain of this utility model can accurately position the interlocking column that is inclined through the water-stop curtain through the cooperation of the first template, the second template and the connecting structure. Secondly, the meshing design of the first toothed plate and the second toothed plate in the connecting structure allows the angle and position between the two templates to be flexibly adjusted and firmly locked, meeting the requirements of the inclination angle of the interlocking column under different construction scenarios, while ensuring the stability of the positioning template during use. Furthermore, the setting of the locking part further enhances the locking effect of the relative position of the two templates, so that the adjusted template position can be maintained stably for a long time, providing a reliable positioning benchmark for the installation of the interlocking column. The overall structure of the positioning template is reasonably designed, the components are tightly connected, and the operation is simple. It is not only easy to assemble and disassemble quickly on the construction site, but also can adapt to complex construction environments. It has high practicality and a wide range of applications, and can significantly improve the efficiency and quality of foundation pit water-stop curtain construction. Attached Figure Description

[0029] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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.

[0030] Please refer to Figure 1 The present invention provides a positioning template for the interlocking column of the foundation pit water-stop curtain, including a first template 3, a second template 4, a connecting structure 5 and a locking component.

[0031] The first template 3 is vertically attached to the water-stop curtain 1, providing a stable vertical reference plane for the entire positioning template. The second template 4 is set at an angle and forms a certain angle with the first template 3 to adapt to the inclined penetration requirements of the interlocking column 2. The connecting structure 5 connects the two templates.

[0032] Furthermore, the connecting structure 5 includes a support tube 51, a first end cap 52, a second end cap 53, a first geared disc 54, a second geared disc 55, and a handle 56. One end of the support tube 51 is a handle that is firmly connected to the first template 3, and the other end is a tube that passes through a receiving hole 511. The first end cap 52 and the second end cap 53 are respectively connected to the two ends of the receiving hole 511, so that the support tube 51 surrounds and forms a hollow inner cavity. The first geared disc 54 and the second geared disc 55 are both located in the cavity, and the first geared disc 54 and the second end cap 53 are connected, and the second geared disc 55 is connected to the handle 56.

[0033] It should be noted that the connection between the support pipe 51 and the first template 3 is made by reliable means such as welding or bolting, to ensure that the two have sufficient strength and stability to withstand various forces generated during construction.

[0034] In this embodiment, the first gear 54 and the second end cap 53 are fixedly connected to the side of the support tube 51 by means of key connection or welding, so as to ensure synchronous rotation between the first gear 54 and the second end cap 53.

[0035] In addition, the handle 56 is connected to the second template 4, and a movable hole 59 is provided through the middle of the second end cover 53. The handle 56 and the docking plate 58 are connected by multiple bolts. A rotating rod 57 is connected between the docking plate 58 and the second gear plate 55. The rotating rod 57 and the movable hole 59 are simultaneously rotated and slidably connected. Through the rotating rod 57, the docking plate 58 and the second gear plate 55 are connected, so that the rotation of the handle 56 and the rotation of the second gear plate 55 are synchronized. This connection method allows the handle 56 to flexibly drive the second gear plate 55 to rotate.

[0036] Since the first toothed disc 54 and the second toothed disc 55 can mesh coaxially with each other, before meshing, the handle 56 can drive the second toothed disc 55 to rotate relative to the support tube 51. After the handle 56 drives the second toothed disc 55 to approach the first toothed disc 54, the first toothed disc 54 and the second toothed disc 55 mesh with each other, thereby preventing the handle 56 from rotating relative to the support tube 51, thus determining the rotation angle of the handle 56 relative to the support tube 51.

[0037] When the handle 56 rotates, the second toothed disc 55 rotates accordingly. When the second toothed disc 55 meshes with the first toothed disc 54, their relative positions are fixed, thereby locking the angular position of the second template 4 relative to the first template 3, ensuring a stable angular and positional relationship between the two templates, and providing a solid foundation for the accurate positioning of the biting column 2.

[0038] Please refer to Figures 1 to 2In this embodiment, the locking component is installed between the first template 3 and the second template 4, including a locking rod 6, a locking frame 7 and a locking cylinder 8. Through the cooperation of the locking rod 6, the locking frame 7 and the locking cylinder 8, the adjusted positions of the two templates are locked to ensure that they remain stable during use and will not be displaced or loosened due to external forces or other factors.

[0039] Specifically, the locking rod 6 is rotatably connected to one side of the first template 3, with one end extending out of the template. The locking frame 7 is rotatably connected to one side of the second template 4, and its position corresponds to the locking rod 6. After the locking rod 6 passes through the locking frame 7, the locking cylinder 8 is pre-tightened on the locking frame 7. The locking cylinder 8 can be a nut or other fastener. By tightening the locking cylinder 8, the locking rod 6 is pressed against the locking frame 7 and fixed by friction, thus restricting the movement of the locking rod 6 within the locking frame 7, thereby effectively preventing the second template 4 from shifting relative to the first template 3 in the horizontal direction.

[0040] This design is not only simple in structure and easy to operate, but also provides a reliable locking effect. Together with the connecting structure 5, it further improves the overall stability of the positioning template.

[0041] Meanwhile, the groove 9 on the side of the second template 4 makes the inner surface of the lock frame 7 and one end of the lock rod 6 flush, ensuring the stability of the lock cylinder 8 pressing and fixing the lock rod 6.

[0042] In an optional embodiment, the connecting structure 5 further includes an elastic element 521, which may be a spring. The elastic element 521 is disposed in the receiving holes 511 at both ends of the support tube 51, with one end connected to the first end cap 52 and the other end abutting against the second toothed disc 55.

[0043] During actual construction, the elastic element 521 pushes the second toothed disc 55 closer to the first toothed disc 54, thereby forcing the second toothed disc 55 and the first toothed disc 54 to mesh naturally. When it is necessary to adjust the position of the handle 56, the handle 56 needs to be pressed to cause the elastic element 521 to contract.

[0044] In another optional embodiment, both ends of the support tube 51 are provided with hexagonal countersunk holes 512, and the first end cap 52 and the second end cap 53 are provided with hexagonal protrusions 513 facing one end of the support tube 51, with the hexagonal protrusions 513 and the hexagonal countersunk holes 512 corresponding to each other.

[0045] The hexagonal countersunk holes 512 at both ends of the support tube 51 cooperate with the hexagonal protrusions 513 on the first end cap 52 and the second end cap 53, which not only increases the tightness and stability of the connection, but also prevents the end caps from rotating or loosening during use.

[0046] In addition, the spring seat located in the middle of the hexagonal protrusion 513 on the first end cover 52 provides a stable mounting base for the elastic element 521, ensuring that the elastic element 521 can be evenly stressed and exert its best elastic effect.

[0047] It is understandable that the diameter of the through hole in the middle of the first template 3 and the second template 4 is larger than the diameter of the interlocking column 2. The purpose of this design is to facilitate the smooth passage of the interlocking column 2 through the positioning template. At the same time, during the installation of the interlocking column 2, a certain position adjustment margin is allowed to ensure that the interlocking column 2 can accurately interlock with the water-stop curtain 1.

[0048] The shape and size of the perforation should be optimized according to the specific specifications and shape of the interlocking post 2 to ensure that the interlocking post 2 can maintain an appropriate gap with the template after passing through the positioning template. This will prevent inaccurate positioning due to excessive gap, or difficulty in installation or damage to the interlocking post 2 due to insufficient gap.

[0049] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0050] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
