Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically to an assembled water-stop screw for building applications. Background Technology

[0002] In the construction industry, water-stop tie rods are specialized tools used for reinforcing and waterproofing concrete wall formwork in building projects. Their main functions are: to prevent the formwork from deforming or bulging due to pressure during concrete pouring by penetrating the formwork on both sides of the wall, and to provide waterproof sealing by using nuts, washers, and other accessories; and to block the seepage path inside the concrete wall by setting a water-stop steel plate (or other water-stop structure) in the middle of the tie rod, thus preventing groundwater or external moisture from seeping through the tie rod holes and ensuring the waterproof performance of the wall.

[0003] The existing process for removing the conical connector of a prefabricated water-stop bolt requires a specific operating procedure: traditional methods necessitate the use of specialized tools, frequently requiring the use of wrenches, cutting equipment, and mechanical hole-reaming tools. This approach has significant technical drawbacks: the use of multiple additional devices leads to cumbersome tool preparation, increases construction costs and tool management difficulties, the multi-step process not only prolongs construction time and reduces efficiency, but the high temperature of gas cutting may damage the surrounding concrete structure, and mechanical operation can easily cause cracks around the bolt hole, affecting the waterproofing performance and structural stability of the wall, making it difficult to meet the requirements of modern building construction for high efficiency, convenience, and high quality. Therefore, a prefabricated water-stop bolt for building applications is proposed. Utility Model Content

[0004] This utility model proposes an assembled water-stop screw rod for construction. By setting an insert block on the mountain-shaped locking block that is symmetrically matched with the insert groove of the conical connecting nut, when it is necessary to remove the conical connecting nut, the insert block of the mountain-shaped locking block can be directly aligned with the insert groove of the conical connecting nut to complete the fitting. Rotating the mountain-shaped locking block with the center point of the thread of the conical connecting nut as the center will drive the conical connecting nut to disengage from the inner water-stop screw rod without the need for additional tools.

[0005] According to one aspect, at least one embodiment of the present invention provides an assembled water-stop screw rod for building, comprising: a water-stop steel sheet, an inner water-stop screw rod fixedly connected to the outer end of the water-stop steel sheet, a conical connecting nut threadedly connected to one end of the inner water-stop screw rod, an outer water-stop screw rod threadedly connected to the other end of the conical connecting nut, a mountain-shaped locking block threadedly connected to the outer water-stop screw rod, a nut provided on the side of the mountain-shaped locking block, and the nut being threadedly connected to the outer water-stop screw rod;

[0006] A conical connecting nut, one end of which has an insertion groove, and a mountain-shaped locking block with an insertion block fixedly connected to one end;

[0007] A mountain-shaped card block, wherein a placement groove is provided on the surface of the mountain-shaped card block, and an auxiliary ring handle is rotatably disposed inside the placement groove.

[0008] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: the insertion groove is symmetrically arranged on the conical connecting nut, and the insertion block is symmetrically arranged on the mountain-shaped locking block.

[0009] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: the placement groove is circular, the auxiliary ring handle is annular, and the auxiliary ring handle and the placement groove are symmetrically arranged in a mountain-shaped locking block.

[0010] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: an auxiliary groove is provided on one side of the placement groove, and an auxiliary block is fixedly connected to the outer wall of the auxiliary ring handle, with the auxiliary block corresponding to the auxiliary groove.

[0011] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: the annular groove in the hollow part of the auxiliary ring handle is chamfered, and the inner wall of the auxiliary ring handle is provided with anti-slip texture.

[0012] For example, at least one embodiment of the present invention provides an assembled water-stop screw for building, which further includes: a limiting groove is formed in the inner wall of the auxiliary block, a movable groove is formed inside the auxiliary groove, a limiting block is movably arranged inside the movable groove, and the limiting block is inserted into the inner wall of the limiting groove.

[0013] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: a spring is provided inside the moving groove, one end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the moving groove.

[0014] For example, at least one embodiment of this utility model provides an assembled water-stop screw for building, which further includes: the outer wall of the limiting block and the inside of the moving groove are in contact with each other, and a rubber pad is fixedly connected to the top of the limiting block.

[0015] The working principle and beneficial effects of this utility model are as follows: By setting an insert block on the mountain-shaped card block that is symmetrically matched with the insert groove of the conical connecting nut, when it is necessary to remove the conical connecting nut, the insert block of the mountain-shaped card block can be directly aligned with the insert groove of the conical connecting nut to complete the fitting. Rotating the mountain-shaped card block with the center point of the thread of the conical connecting nut as the center will drive the conical connecting nut to disengage from the inner water-stop screw without the need for additional tools.

[0016] The symmetrically arranged circular placement grooves and annular auxiliary handles on the surface of the mountain-shaped locking block allow for easier rotation of the block by rotating the auxiliary handle to a 90-degree angle with it. The auxiliary block and grooves work together to apply force. The anti-slip texture and chamfered edges on the inner wall of the auxiliary handle enhance grip stability and comfort during force application. The limiting and resetting structure, consisting of a limiting groove on the inner wall of the auxiliary block, a moving groove within the auxiliary groove, a limiting block, and a spring, allows the auxiliary handle to be fixed in place when not in use by inserting the limiting block into the limiting groove. When in use, pressing the limiting block compresses the spring, disengaging the limiting block from the limiting groove. The spring's elastic resetting performance ensures that the auxiliary handle automatically fixes itself after use, without affecting the normal operation of the mountain-shaped locking block.

[0017] In addition, the threaded connection of the nut on the outer water-stop screw can adjust the clamping force and distance of the mountain-shaped clamping block for templates of different thicknesses and materials, expanding the applicability of the mountain-shaped clamping block. Through the coordinated cooperation of various components, the entire structure realizes the convenient disassembly of the cone-shaped connecting nut, simplifies the construction process, improves construction efficiency, reduces tool dependence and construction costs, and enhances the stability of operation and the applicability of the device.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Refer to the instruction manual appendix Figure 1-4A modular water-stop screw rod for construction includes: a water-stop steel sheet 1, an inner water-stop screw rod 2 fixedly connected to the outer end of the water-stop steel sheet 1, a conical connecting nut 3 threadedly connected to one end of the inner water-stop screw rod 2, an outer water-stop screw rod 4 threadedly connected to the other end of the conical connecting nut 3, a mountain-shaped locking block 5 threadedly connected to the outer water-stop screw rod 4, a nut 6 provided on the side of the mountain-shaped locking block 5, and the nut 6 being threadedly connected to the outer water-stop screw rod 4; a connecting nut 3, one end of the conical connecting nut 3 having an insertion groove 8, and one end of the mountain-shaped locking block 5 fixedly connected to an insertion block 7; the mountain-shaped... The card block 5 has a placement groove 9 on its surface, and an auxiliary ring handle 10 is rotatably installed inside the placement groove 9. When it is necessary to remove the conical connecting nut 3 from the concrete, the card block 5 that has been removed is taken out first, and the insert block 7 part of the card block 5 is aligned with the insert groove 8 part of the conical connecting nut 3. Since the shape and size of the insert block 7 and the insert groove 8 are perfectly matched and symmetrically arranged, the assembly of the interlocking structure can be completed quickly. At this time, the rotational force is applied to the card block 5 with the center point of the thread of the conical connecting nut 3 as the center.

[0031] During rotation, the symmetrically arranged insert blocks 7 and insert slots 8 form a stable force transmission path. The rotational power of the mountain-shaped locking block 5 is transmitted to the conical connecting nut 3 through the insert blocks 7, causing the conical connecting nut 3 to start rotating from the inner water-stop screw 2. As the rotation continues, the conical connecting nut 3 gradually separates from the threads of the inner water-stop screw 2 and eventually detaches from the concrete. This design eliminates the need for additional disassembly tools such as wrenches and pliers, and the disassembly operation can be completed solely through the structure of the mountain-shaped locking block 5 itself, greatly simplifying the construction process and improving disassembly efficiency.

[0032] Then, the insertion slots 8 are symmetrically arranged on the conical connecting nut 3, and the insertion blocks 7 are symmetrically arranged on the mountain-shaped locking block 5. When the mountain-shaped locking block 5 drives the conical connecting nut 3 to rotate, the two sets of symmetrically arranged insertion slots 8 and insertion blocks 7 can make the force evenly distributed on both sides of the conical connecting nut 3, effectively avoiding the phenomenon of skewing or jamming during the rotation, thereby ensuring the stability and smoothness of the rotation process.

[0033] Subsequently, the placement groove 9 is circular, and the auxiliary ring handle 10 is annular. The auxiliary ring handle 10 and the placement groove 9 are symmetrically arranged on the mountain-shaped locking block 5. The symmetrical arrangement of the placement groove 9 and the auxiliary ring handle 10 allows the operator to apply force on both sides simultaneously when rotating the auxiliary ring handle 10, thereby making it easier to rotate the mountain-shaped locking block 5 and reducing the difficulty of operation.

[0034] Next, an auxiliary groove 11 is provided on one side of the placement groove 9, and an auxiliary block 12 is fixedly connected to the outer wall of the auxiliary ring handle 10. The auxiliary block 12 corresponds to the auxiliary groove 11. The length and width of the auxiliary groove 11 are adapted to the size of the auxiliary block 12 to ensure that the auxiliary block 12 can move smoothly in the auxiliary groove 11. When the auxiliary ring handle 10 needs to be used, the operator rotates the auxiliary ring handle 10 out of the placement groove 9 so that it is perpendicular to the mountain-shaped locking block 5 at a 90-degree angle. At this time, the auxiliary block 12 is located at the opening of the auxiliary groove 11. The operator applies force to the auxiliary ring handle 10, and the auxiliary block 12 moves in the auxiliary groove 11, thereby transmitting the force to the mountain-shaped locking block 5 and achieving the effect of driving the mountain-shaped locking block 5 to rotate.

[0035] At this point, the annular groove inside the auxiliary ring handle 10 is chamfered, and the inner wall of the auxiliary ring handle 10 is provided with anti-slip texture. This design can reduce the frictional resistance when the operator's hand contacts the auxiliary ring handle 10, avoid hand scratches, and improve the comfort of operation. At the same time, the anti-slip texture on the inner wall of the auxiliary ring handle 10 is made of parallel stripes with a spacing of 2 mm and a depth of 1 mm. This anti-slip texture can increase the friction between the hand and the auxiliary ring handle 10, allowing the operator to grip the auxiliary ring handle 10 more firmly when applying force, effectively preventing operational errors caused by hand slippage, and ensuring the safety and stability of the disassembly process.

[0036] Next, a limiting groove 16 is formed on the inner wall of the auxiliary block 12, and a moving groove 13 is formed inside the auxiliary groove 11. A limiting block 14 is moved inside the moving groove 13 and is inserted into the inner wall of the limiting groove 16. The above structure is used to drive the limiting block 14 to insert into the limiting groove 16, ensuring the fixing effect of the auxiliary ring handle 10 inside the placement groove 9, without affecting the normal operation of the mountain-shaped locking block 5. When the auxiliary ring handle 10 needs to be used, the limiting block 14 can be pressed to move inside the moving groove 13, so that the limiting block 14 is disengaged from the limiting groove 16, and then the auxiliary ring handle 10 can be operated.

[0037] Secondly, a spring 15 is installed inside the moving groove 13. One end of the spring 15 is fixedly connected to the limiting block 14, and the other end of the spring 15 is fixedly connected to the moving groove 13. The spring 15 has good elasticity and corrosion resistance. When the operator needs to use the auxiliary ring handle 10, he presses the limiting block 14 to move it inside the moving groove 13, compressing the spring 15, thereby causing the limiting block 14 to disengage from the limiting groove 16. At this time, the auxiliary ring handle 10 can rotate freely. When the operator releases the limiting block 14, the spring 15 restores its elastic deformation, driving the limiting block 14 to reset and re-insert into the limiting groove 16, thus realizing the automatic fixing of the auxiliary ring handle 10.

[0038] Finally, the outer wall of the limiting block 14 fits into the interior of the moving groove 13, and a rubber pad is fixedly connected to the top of the limiting block 14; this ensures that the limiting block 14 moves smoothly within the moving groove 13, while also ensuring the stability of the limiting block 14 during movement. The rubber pad is fixedly connected to the top of the limiting block 14. The rubber pad is 3 mm thick and its material has good elasticity and wear resistance. The rubber pad increases the comfort of the operator when pressing the limiting block 14, making the pressing operation easier and more convenient.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
