Description

Technical Field

[0001] This utility model belongs to the field of water-stop screw technology, specifically relating to a water-stop screw for the corner of an ultra-thick wall. Background Technology

[0002] Due to stress concentration and complex formwork splicing at the corners of ultra-thick walls, water seepage is a potential hazard. Water-stop bolts block the seepage path through the intermediate water-stop plate, while simultaneously binding the formwork to prevent deformation, enhancing waterproof performance and ensuring structural stability. They are especially suitable for underground and humid environments.

[0003] Most water-stop bolts have several drawbacks in use. For example, the water-stop plates on most water-stop bolts are welded and fixed. If the water-stop plates are bent or damaged, the entire water-stop bolt needs to be replaced, wasting materials. Furthermore, after installation, dust may enter the water-stop bolts during construction, making disassembly difficult and affecting work efficiency. Therefore, it is necessary to develop an ultra-thick water-stop bolt for wall corners to overcome these shortcomings. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses a water-stop screw rod for ultra-thick wall corners. By setting a limiting component, the water-stop plate can be fixed on the screw rod, preventing the formwork from deforming due to concrete pressure. This facilitates the replacement of the water-stop plate, is simple to operate, and prevents dust from entering the screw rod, making it easy to remove the formwork.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A water-stop bolt for ultra-thick wall corners includes a bolt, a water-stop plate, two angle steels, and four iron plates, and also includes:

[0007] Two fixing blocks are slidably mounted on the screw rod. Two angle steels are fixedly connected to the two fixing blocks respectively. Both angle steels are slidably connected to the screw rod. Threaded sleeves are rotatably installed inside each of the two fixing blocks. Both threaded sleeves are threadedly connected to the screw rod. The water-stop plate is slidably mounted on the screw rod and located between the two angle steels. Four iron plates are fixedly mounted on the two angle steels respectively.

[0008] Two fixed shells are respectively fixedly installed on two fixed blocks. Sliding blocks are slidably installed inside each of the two fixed shells. Several tension springs that are fixed to the corresponding fixed blocks are fixedly installed on each of the two sliding blocks.

[0009] A limiting component is located on the waterstop sheet and is used to fix the position of the waterstop sheet;

[0010] Two sets of drive components are located in two fixed blocks and are used to drive the rotation of two threaded sleeves.

[0011] When in use, insert the screw into the waterstop plate. When the screw is inserted into the appropriate position, the waterstop plate can be fixed on the screw by the set limiting component (pin), and it is convenient to replace the waterstop plate. The operation is simple and convenient. The waterstop plate can effectively block the water seepage path. When water seeps into the external wall along the screw gap, the waterstop plate will change the water flow direction and extend the seepage path, thereby preventing water from entering the room.

[0012] Next, the screw is placed between two templates set at 90°. Then, both ends of the screw pass through the two templates and extend to the outside. Then, the workers insert angle steel into the screw. When the threaded sleeve contacts the screw, the threaded sleeve can be rotated by the set drive component. Under the action of the thread, the threaded sleeve can be moved on the screw towards the waterstop plate. When the angle steel and the two iron plates are in close contact with the template, the two angle steel can clamp the two templates set at 90°, clamping the two templates to prevent the template from deforming or bursting due to concrete pressure.

[0013] As the angle steel moves, the two ends of the screw press against two sliding blocks, causing them to slide away from each other. At the same time, several tension springs are stretched to ensure that the two ends of the screw are not exposed to the outside world, preventing dust from entering the screw and facilitating the removal of the template.

[0014] Furthermore, the limiting component includes:

[0015] A pin is inserted into the water-stop plate, and the lower end of the pin passes through the screw rod, and the lower end of the pin is engaged with the screw rod.

[0016] Furthermore, the driving component includes:

[0017] The power chamber is located within a fixed block. A first bevel gear is rotatably mounted within the power chamber. The first bevel gear is fixedly connected to a threaded sleeve. A second bevel gear is meshed with the top of the first bevel gear. A disc is fixedly mounted on the top of the second bevel gear.

[0018] A plurality of grooves are formed inside the disk. A limiting strip is slidably installed inside the power cavity and on one side of the disk. One end of the limiting strip extends into the corresponding groove and is inserted into the corresponding groove. A plurality of springs fixed to the inner wall of the power cavity are fixedly installed on the limiting strip. The other end of the limiting strip passes through the power cavity and extends to the outside.

[0019] In use, the screw is placed between two templates set at 90°. Both ends of the screw penetrate the two templates and extend to the outside. An angle iron is then inserted into the screw. When the threaded sleeve contacts the screw, the limiting strip is pulled away from the disc, causing several springs to compress. When one end of the limiting strip disengages from its corresponding groove, the disc is rotated, driving the second bevel gear to rotate. The second bevel gear then drives the first bevel gear, which in turn drives the threaded sleeve to rotate. Under the action of the threads, the threaded sleeve can move towards the waterstop plate on the screw. When the angle iron and the two iron plates are in close contact with the templates, the disc is stopped. The two angle irons clamp the two templates set at 90°, preventing deformation or bursting of the templates due to concrete pressure.

[0020] Furthermore, a first magnet is fixedly installed at the bottom end of the pin, and a second magnet is magnetically connected to the bottom of the first magnet. The second magnet is fixedly connected to the waterstop plate.

[0021] The first magnet and the second magnet are magnetically connected, which can fix the water-stop plate on the screw.

[0022] Furthermore, the grooves are distributed in a ring at equal intervals on the disk, ensuring that the disk can stop rotating and be fixed at any position.

[0023] Furthermore, the upper end of the disc passes through the power cavity and is fixedly mounted with an operating panel, which facilitates the operator to rotate the disc.

[0024] Furthermore, both the second bevel gear and the disk are rotatably connected to the power cavity, ensuring that both the second bevel gear and the disk can rotate within the power cavity.

[0025] Furthermore, the cross-section of the iron sheet is triangular, ensuring that the angle steel and both iron sheets can be in close contact with the template.

[0026] The beneficial effects of this utility model are:

[0027] 1. The water-stop screw rod at the corner of the ultra-thick wall is inserted into the water-stop plate. When the screw rod is inserted to the appropriate position, the water-stop plate can be fixed on the screw rod by the set limiting component, and the water-stop plate can be replaced easily. The operation is simple and convenient.

[0028] 2. The water-stop tie rod at the corner of the ultra-thick wall has two sliding blocks pressed against each other at both ends as the angle steel moves. At the same time, several tension springs are stretched to ensure that the two ends of the tie rod are not exposed to the outside world, preventing dust from entering the tie rod and facilitating the removal of the formwork.

[0037] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0038] Example 1: This example provides a water-stop bolt for the corner of an ultra-thick wall, including a bolt 1, a water-stop plate 2, two angle steels 3, and four iron plates 4, and also includes:

[0039] Two fixing blocks 5 are slidably mounted on the screw rod 1. Two angle steels 3 are respectively set at the inner ends of the two fixing blocks 5. The two angle steels 3 are slidably connected to the screw rod 1. Threaded sleeves 6 are rotatably installed inside the two fixing blocks 5. The two threaded sleeves 6 are threadedly connected to the screw rod 1. Waterstop plate 2 is slidably mounted on the screw rod 1 and located between the two angle steels 3. Four iron plates 4 are respectively fixedly mounted on the bent sides of the two angle steels 3, so that the two angle steels 3 become a right-angled triangular structure.

[0040] Two fixed shells 7 are fixedly installed on the outer ends of two fixed blocks 5 respectively. Sliding blocks 8 are slidably installed inside each of the two fixed shells 7. Several tension springs 9 that are fixed to the corresponding fixed blocks 5 are fixedly installed on each of the two sliding blocks 8.

[0041] A limiting component is located on the waterstop 2 and is used to fix the position of the waterstop 2.

[0042] Two sets of drive components are located in two fixed blocks 5 respectively, and are used to drive the two threaded sleeves 6 to rotate.

[0043] The screw 1 is inserted into the waterstop 2. When the screw 1 is inserted to the appropriate position, the waterstop 2 can be fixed on the screw 1 by the set limiting component, and the waterstop 2 can be easily replaced. The operation is simple and convenient. The waterstop 2 can effectively block the water penetration path. When water seeps into the external wall along the gap of the screw 1, the waterstop 2 will change the water flow direction and extend the penetration path, thereby preventing water from entering the room.

[0044] Next, screw 1 is placed between two templates set at 90°. Then, both ends of screw 1 pass through the two templates and extend to the outside. Then, the workers insert angle steel 3 into screw 1. When threaded sleeve 6 contacts screw 1, the threaded sleeve 6 can be rotated by the set drive component. Under the action of the thread, threaded sleeve 6 can be moved on screw 1 towards waterstop plate 2. When angle steel 3 and two iron plates 4 are in close contact with the template, the two angle steel 3 can clamp the two templates set at 90°, clamping the two templates to prevent the template from deforming or bursting due to concrete pressure.

[0045] As the angle steel 3 moves, the two ends of the screw 1 press against the two sliding blocks 8 respectively, causing them to slide and move away from each other. At the same time, several tension springs 9 are stretched to ensure that the two ends of the screw 1 are not exposed to the outside world, preventing dust from entering the screw 1 and facilitating the removal of the template.

[0046] In this embodiment, the limiting component includes:

[0047] Pin 10 is inserted into the waterstop plate 2. The lower end of pin 10 passes through the screw 1 and is engaged with the screw 1.

[0048] The process involves inserting the screw 1 into the waterstop 2. When the screw 1 is inserted to the appropriate position, the pin 10 is inserted into the waterstop 2. Then, the lower end of the pin 10 passes through the screw 1, which can fix the waterstop 2 on the screw 1 and facilitate the replacement of the waterstop 2. The operation is simple and convenient. The waterstop 2 can effectively block the water penetration path. When water seeps into the external wall along the gap of the screw 1, the waterstop 2 will change the direction of water flow and extend the penetration path, thereby preventing water from entering the room.

[0049] In this embodiment, the driving component includes:

[0050] The power chamber 11 is located inside the fixed block 5. A first bevel gear 12 is rotatably installed inside the power chamber 11. The first bevel gear 12 is fixedly connected to the threaded sleeve 6. A second bevel gear 13 is meshed with the top of the first bevel gear 12. A disc 14 is fixedly installed on the top of the second bevel gear 13.

[0051] A number of grooves 15 are formed inside the disc 14. A limiting strip 16 is slidably installed inside the power cavity 11 and on one side of the disc 14. One end of the limiting strip 16 extends into the corresponding groove 15 and is inserted into the corresponding groove 15. A number of springs 17 fixed to the inner wall of the power cavity 11 are fixedly installed on the limiting strip 16. The other end of the limiting strip 16 passes through the power cavity 11 and extends to the outside.

[0052] Next, the screw 1 is placed between two templates set at 90°. Then, both ends of the screw 1 pass through the two templates and extend to the outside. Then, the worker inserts the angle steel 3 into the screw 1. When the threaded sleeve 6 contacts the screw 1, the limiting strip 16 is pulled to slide away from the disc 14. At the same time, several springs 17 are compressed and contracted. When one end of the limiting strip 16 is disengaged from the corresponding groove 15, the disc 14 is rotated and the second bevel gear 13 is driven to rotate. The second bevel gear 13 drives the first bevel gear 12 that meshes with it to rotate. The first bevel gear 12 drives the threaded sleeve 6 to rotate. Under the action of the thread, the threaded sleeve 6 can be displaced on the screw 1 towards the waterstop 2. When the angle steel 3 and the two iron plates 4 are in close contact with the templates, the rotation of the disc 14 is stopped. The two angle steels 3 can clamp the two templates set at 90°, clamping the two templates to prevent the templates from deforming or bursting due to concrete pressure. Example

[0055] The first magnet 19 and the second magnet 20 are magnetically connected, which can fix the water-stop plate 2 on the screw 1. Example

[0056] This embodiment provides a water-stop bolt for the corner of an ultra-thick wall, which, in addition to the technical solution of the above embodiment, also has the following technical features.

[0057] In this embodiment, a number of grooves 15 are distributed in a ring at equal intervals on the disk 14.

[0066] In this embodiment, the cross-section of the iron sheet 4 is triangular.

[0067] In this process, it is ensured that the angle steel 3 and the two iron plates 4 can be in close contact with the template.

[0068] Working principle: Insert the screw 1 into the waterstop plate 2. When the screw 1 is inserted to the appropriate position, insert the pin 10 into the waterstop plate 2. Then, the lower end of the pin 10 passes through the screw 1. Finally, the first magnet 19 and the second magnet 20 are magnetically connected, which can fix the waterstop plate 2 on the screw 1 and facilitate the replacement of the waterstop plate 2. The operation is simple and convenient. The waterstop plate 2 can effectively block the water penetration path. When water seeps into the external wall along the gap of the screw 1, the waterstop plate 2 will change the water flow direction and extend the penetration path, thereby preventing water from entering the room.

[0069] Next, the screw 1 is placed between two templates set at 90°. Then, both ends of the screw 1 pass through the two templates and extend to the outside. Then, the worker inserts the angle steel 3 into the screw 1. When the threaded sleeve 6 contacts the screw 1, the limiting strip 16 is pulled to slide away from the disc 14. At the same time, several springs 17 are compressed and contracted. When one end of the limiting strip 16 is disengaged from the corresponding groove 15, the operating disc 18 is rotated and the disc 14 is rotated. The disc 14 drives the second bevel gear 13 to rotate. The second bevel gear 13 drives the first bevel gear 12 that meshes with it to rotate. The first bevel gear 12 drives the threaded sleeve 6 to rotate. Under the action of the thread, the threaded sleeve 6 can be displaced on the screw 1 towards the waterstop 2. When the angle steel 3 and the two iron plates 4 are in close contact with the template, the operation disc 18 is stopped. The two angle steels 3 can clamp the two templates set at 90°, clamping the two templates to prevent the templates from deforming or bursting due to concrete pressure.

[0070] As the angle steel 3 moves, the two ends of the screw 1 press against the two sliding blocks 8 respectively, causing them to slide and move away from each other. At the same time, several tension springs 9 are stretched to ensure that the two ends of the screw 1 are not exposed to the outside world, preventing dust from entering the screw 1 and facilitating the removal of the template.
