Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a height-adjustable and precisely positioned anti-buoyancy anchor fixing and waterproofing device. Background Technology

[0002] With the development of urban construction, the development of underground space is receiving increasing attention. Underground parking garages, underground shopping malls, and large pool structures present challenges in balancing the buoyancy of groundwater over large areas. When the structure's own weight is insufficient to resist the buoyancy generated by groundwater, the construction method of adding anti-buoyancy anchors is typically employed. During the construction of anti-buoyancy anchors, the length of the exposed section of the anchor must be controlled when it is inserted into the anchor hole. To ensure that the exposed section meets design requirements, a stress point must be provided to prevent the anchor from sinking. Traditional anti-buoyancy anchor construction involves welding a steel bar longer than the diameter of the anchor hole to each anchor rod. This welded steel bar is used to secure the anti-buoyancy anchor at the opening of the anchor hole, thereby controlling the length of the exposed section of the anchor.

[0003] Patent document CN221072757U discloses an anti-buoyancy anchor fixing and waterproofing device, which includes a circular water-stop steel plate, an anti-buoyancy anchor, and an annular fixing bracket. The circular water-stop steel plate is fixed to the top of the annular fixing bracket, which includes a ring-shaped reinforcing bar and a supporting reinforcing bar. The upper end of the supporting reinforcing bar is fixed to the outer edge of the circular water-stop steel plate, and the lower end is fixed to the ring-shaped reinforcing bar. The circular water-stop steel plate completely covers the anchor hole. The circular water-stop steel plate is perpendicular to the anti-buoyancy anchor. The circular water-stop steel plate and the anti-buoyancy anchor are fixedly connected at the junction of the anchoring section and the exposed section of the anti-buoyancy anchor. The circular water-stop steel plate, the ring-shaped reinforcing bar, the supporting reinforcing bar, and the anti-buoyancy anchor are fixedly connected. The anti-buoyancy anchor passes through the anchor bar hole on the circular water-stop steel plate and is inserted into the anchor hole. When the anti-buoyancy anchor is subjected to external disturbance, gaps are less likely to form between the circular water-stop steel plate and the anti-buoyancy anchor, thereby reducing the upward leakage of groundwater through gaps around the anti-buoyancy anchor and increasing the waterproof and seepage-proof capability at the joint.

[0004] In existing anti-buoyancy anchor fixing and waterproofing devices, the circular water-stop steel plate needs to be fixedly connected to the junction of the anchorage section and the exposed section of the anti-buoyancy anchor. The height of the supporting steel bar (circular water-stop steel plate) cannot be freely adjusted according to the actual situation, which is not flexible enough when distinguishing between the anchorage section and the exposed section of the anti-buoyancy anchor. When placing the ring fixing bracket, it is not convenient to make fine adjustments and quickly position the ring fixing bracket to make the circular water-stop steel plate and the ring steel bar coaxial with the anchor hole. Coaxiality helps to improve the stability of the anti-buoyancy anchor. Utility Model Content

[0005] To overcome the problems existing in the prior art, this utility model provides a height-adjustable and precisely positioned anti-buoyancy anchor fixing and waterproofing device. It can adjust the height of the circular water-stop steel plate according to the needs to distinguish between the anchoring section and the exposed section of the anti-buoyancy anchor, and can also fine-tune and quickly position the ring fixing bracket.

[0006] A construction method for a fixed structure of a high-rise building curtain wall includes a ring-shaped steel bar, a circular water-stop steel plate above the ring-shaped steel bar, and a circular water-stop steel plate connected to the ring-shaped steel bar by a plurality of adjusting supports. The circular water-stop steel plate has anchor holes along its circumference for passing through anti-buoyancy anchor rods, and the lower end of the anti-buoyancy anchor rods extends into the anchor holes. The adjusting supports include a kit fixed to the ring-shaped steel bar. The adjusting supports include the kit and a sliding plate. The sliding plate is disposed inside the kit and is slidably connected to the kit. The lower end of the kit is fixed to the ring-shaped steel bar, and the upper end of the sliding plate is fixed to the circular water-stop steel plate. A bolt is threaded through and screwed onto the kit. A plurality of positioning screw holes are provided on the sliding plate. The bolt (33) fixes the sliding plate at different positions to the kit by passing through any of the positioning screw holes on the sliding plate.

[0007] Furthermore, the number of the adjusting support members is three, and the three adjusting support rods are evenly spaced along the circumference of the circular waterstop steel sheet and the annular steel bar.

[0008] Furthermore, the positioning screw holes are provided in seven places.

[0009] Furthermore, the diameter of the circular water-stop steel sheet is larger than the diameter of the anchor bolt hole.

[0010] Furthermore, the inner diameter of the annular reinforcing bar is larger than the diameter of the anchor hole.

[0011] Furthermore, it also includes a positioning and stabilizing mechanism, which includes an adjusting rod that passes through and slides on the circular water-stop steel sheet, a rod sleeve fixedly connected to the lower end of the adjusting rod, a connecting plate fixedly connected to one side of the kit, each connecting plate fixedly connected to a stabilizing plate, a plurality of sliding members sliding circumferentially on the stabilizing plate, the lower end of a rotating plate hinged to the sliding member, the upper end of each rotating plate hinged to the rod sleeve, and an arc plate fixedly connected to the end of the sliding member away from the central axis of the annular steel bar.

[0012] Furthermore, the center of the stabilizing plate coincides with the central axis of the annular reinforcing bar and the circular water-stop steel sheet.

[0013] Furthermore, when the circular water-stop steel sheet is adjusted to its highest point, the arc plate remains within the anchor bolt hole.

[0014] Furthermore, an adjustment handle is fixedly connected to the upper end of the adjustment rod.

[0015] Furthermore, the mounting plate is provided with a sliding groove, and the sliding member slides within the sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are: In this invention, by removing the bolts and pulling the circular waterstop steel plate, the height of the circular waterstop steel plate can be adjusted. When distinguishing between the anchoring section and the exposed section of the anti-buoyancy anchor rod, the height of the circular waterstop steel plate can be flexibly adjusted so that the circular waterstop steel plate can be fixedly connected to the junction of the anchoring section and the exposed section of the anti-buoyancy anchor rod. Then, the bolts are threaded into the positioning screw holes and the fittings in appropriate positions to fix the height of the circular waterstop steel plate. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] A height-adjustable, precisely positioned anti-buoyancy anchor fixing and waterproofing device, such as... Figures 1 to 3As shown, the system includes a ring-shaped reinforcing bar 1, with a circular water-stop steel plate 2 positioned above it. The circular water-stop steel plate 2 is connected to the ring-shaped reinforcing bar 1 via multiple adjusting supports 3. Each adjusting support includes a kit 31 and a sliding plate 32. The length of the adjusting support 3 is adjustable through a sliding connection between the sliding plate 32 and the kit 31. Anchor bar holes 21 are provided circumferentially on the circular water-stop steel plate 2. These holes are used to pass through anti-buoyancy anchor rods 4, with the lower end of the anti-buoyancy anchor rod 4 extending into the anchor rod hole 5. The adjusting support 3 includes a kit 31 fixedly connected to the ring-shaped reinforcing bar 1. In this embodiment, the kit 31 is made of steel, and its lower end is welded to the ring-shaped reinforcing bar 1. A sliding plate 32 slides within the kit 31. The sliding plate 32 is also made of steel, with its upper end welded to the lower end face of the circular water-stop steel plate 2. The lower end of the sliding plate 32 is located within the kit 31, and the sliding plate 32 is slidably connected to the kit. A bolt 33 is threaded through and connected to the assembly 31. Multiple positioning screw holes 34 are evenly spaced along the length of the sliding plate 32. In this embodiment, seven holes are provided. The bolt 33, threaded through the assembly 31, allows the sliding plate 32 to slide within the assembly 31, passing through the positioning screw holes 34 at different positions to adjust the length of the support component. After removing the bolts 33, the circular waterstop steel plate 2 is fixedly connected to the upper end of the sliding plate 32. Pulling the circular waterstop steel plate 2 allows the sliding plate 32 to slide within the assembly 31, thereby adjusting the height of the circular waterstop steel plate 2. This allows for flexible adjustment of the height of the circular waterstop steel plate 2 to accommodate different heights of the anchoring section and exposed section of the anti-buoyancy anchor rod 4 in different embodiments. Finally, the bolts 33 are threaded into the positioning screw holes 34 at appropriate positions and onto the assembly 31 to fix the height of the circular waterstop steel plate 2. In this embodiment, three adjustment support members 3 are provided, and the three adjustment support rods are evenly spaced around the circular waterstop steel plate 2 and the annular steel bar 1.

[0024] Furthermore, such as Figure 1-3 As shown, the diameter of the circular water-stop steel sheet 2 is larger than the diameter of the anchor bolt hole 5, and the inner diameter of the ring steel bar 1 is larger than the diameter of the anchor bolt hole 5.

[0025] Furthermore, such as Figure 1-3As shown, it also includes a positioning and stabilizing mechanism. The positioning and stabilizing mechanism includes an adjusting rod 6 that passes through and slides on a circular water-stop steel plate 2. The lower end of the adjusting rod 6 is fixedly connected to a rod sleeve 7. Each side of the kit 31 near the center of the annular steel bar 1 is fixedly connected to a connecting plate 8. Each connecting plate 8 is fixedly connected to an mounting plate 9. The center of the mounting plate 9 coincides with the central axis of the annular steel bar 1 and the circular water-stop steel plate 2. Multiple sliding parts 10 slide circumferentially on the mounting plate 9. The upper end of the sliding part 10 is hinged to the lower end of the rotating plate 11. The upper end of each rotating plate 11 is hinged to a connecting rod sleeve 7. The lower end of each sliding part 10 is fixedly connected to an arc plate 12. The anti-buoyancy anchor rod 4 is passed through the anchor bar hole 21, and the annular steel bar 1 is placed around the anchor rod hole 5, with the arc plate 12 extending into the anchor rod hole 5. Then, the height of the circular waterstop steel plate 2 is adjusted (no steel bars longer than the diameter of the anchor bar hole 21 are welded to the rod body of each anti-buoyancy anchor rod 4). The adjusting rod 6 is pressed down, causing the adjusting rod 6 to move downward relative to the circular waterstop steel plate 2. The rotating plate 11 pushes the sliding parts 10 away from each other, so that each arc plate 12 simultaneously approaches and fits against the inner wall of the anchor rod hole 5. At the same time, the circular waterstop steel plate 2 and the annular steel bar 12 move closer and fit against the inner wall of the anchor rod hole 5. The reinforcing bar 1 will gradually move to be coaxial with the anchor hole 5. The adjusting rod 6 and the anti-buoyancy anchor 4 will be welded to the circular waterstop steel plate 2. Finally, the adjusting rod 6, the moving plate 7, the connecting plate 8, the mounting plate 9, the sliding part 10, the rotating plate 11 and the arc plate 12 will cooperate to facilitate the fine adjustment and quick centering of the annular fixed bracket (circular waterstop steel plate 2, annular reinforcing bar 1 and adjusting support 3), so that the rod body of the anti-buoyancy anchor 4 at the anchor hole 5 can be aligned, and the circular waterstop steel plate 2 and the annular reinforcing bar 1 are coaxial with the anchor hole 5. Coaxiality helps to improve the stability of the anti-buoyancy anchor 4.

[0026] Furthermore, such as Figure 1-3 As shown, the anchoring section of the anti-buoyancy anchor 4 (located on the rod body inside the anchor hole 5) is aligned by setting an alignment bracket.

[0027] Furthermore, such as Figure 1-3 As shown, the upper end of the adjusting rod 6 is fixedly connected to the adjusting handle 13. The adjusting handle 13 is set to facilitate the pulling or pressing adjustment of the adjusting rod 6. When the arc plate 12 is placed into the anchor bolt hole 5, the adjusting rod 6 can be pulled upward as needed to prevent the arc plate 12 from contacting the anchor bolt hole 5, so that the arc plate 12 can be placed into the anchor bolt hole 5.

[0028] Furthermore, such as Figure 1-3 As shown, the mounting plate 9 has a sliding groove 91. In this embodiment, there are three sliding grooves 91, and the sliding member 10 slides in the sliding groove 91.

[0029] Furthermore, such as Figure 1-3 As shown, when the circular waterstop steel plate 2 is adjusted to the highest point (when the bolt 33 passes through the positioning screw hole 34 located at the bottom), the arc plate 12 is always located inside the anchor bolt hole 5.

[0030] The working principle of the anti-buoyancy anchor fixing and waterproofing device in this embodiment is as follows: First, the anti-buoyancy anchor 4 is inserted into the anchor hole 5. The anchoring section of the anti-buoyancy anchor 4 is aligned using a centering bracket. Then, the annular steel bar 1 is fitted onto the anti-buoyancy anchor 4, allowing the anchor 4 to pass through the anchor bar hole 21. The annular steel bar 1 is placed on the ground surface around the anchor hole 5. By removing the bolts 33, the height of the circular water-stop steel plate 2 is adjusted by pulling it. This allows for flexible adjustment of the height of the circular water-stop steel plate 2 when distinguishing between the anchoring section and the exposed section of the anti-buoyancy anchor. Then, the bolts 33 are threaded into the positioning screw holes 34 and the fitting 31 at appropriate positions to fix the height of the circular water-stop steel plate 2. The circular water-stop steel plate 2 is welded to the junction of the anchoring section and the exposed section of the anti-buoyancy anchor 4. Finally, the adjusting rod 6 is pressed down to adjust the arc plates 1... 2. Simultaneously, approach and fit close to the inner wall of the anchor hole 5, fine-tune and quickly center the annular fixing bracket (circular water-stop steel plate 2, annular steel bar 1, and adjusting support 3), then press down the adjusting rod 6 with a heavy object (such as a stone), and weld the adjusting rod 6 to the circular water-stop steel plate 2, which helps to further improve the stability of the anti-buoyancy anchor 4. Then, weld steel bars with a length greater than the diameter of the anchor hole 21 onto the rod body of each anti-buoyancy anchor 4. After the material is cut, grout is injected into the anchor hole 5 through the grouting pipe 14, and then the concrete cushion layer is poured. The circular water-stop steel plate 2 is placed in the middle of the concrete cushion layer to enhance the water-stopping effect at the anchor hole 5. After the cushion layer is poured, water discharge construction is carried out according to the conventional method. There are gaps in the splicing of the waterproof membrane at the anti-buoyancy anchor 4. A rubber water-stop ring is set around the anti-buoyancy anchor 4, and then the rubber water-stop ring is filled with asphalt waterproof sealant.

[0031] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
