Description

Technical Field

[0001] This utility model relates to the field of construction anchor fixing technology, and in particular to a device for fixing and sealing post-installed construction anchors. Background Technology

[0002] During construction, fine aggregate concrete prepared by a commercial concrete plant is poured into the anchor holes. Before the fine aggregate concrete initially sets, prepared anchor steel bars are inserted into it. After the fine aggregate concrete reaches its strength, the anti-buoyancy anchor is tested and accepted. The anchor steel bars are inserted after grouting. The fine aggregate concrete prepared by the commercial concrete plant is poured directly, and the grouting pressure does not need to be controlled during the pouring process. The anchor is set vertically in a pre-embedded steel sleeve and generally uses fine-rolled threaded steel bars. For example, fine-rolled threaded steel bars with a diameter of 100 mm are used. The top of the anti-buoyancy anchor is higher than the top of the pre-embedded steel sleeve to provide anti-buoyancy and ensure the stability of the structure under the action of groundwater buoyancy.

[0003] The pre-embedded steel sleeve is equipped with a steel mesh, located below the water-stop flange. Multiple bottom plate reinforcement bars are provided above the steel pad plate, symmetrically arranged around the outer circumference of the steel pad plate, with one end welded and fixed to the steel pad plate. Continuing reinforcement bars are provided between the top reinforcement bars and welded between the symmetrical bottom plate reinforcement bars. Finally, sealing concrete is poured on top, with its top surface flush with the top surface of the foundation slab. However, existing post-installed construction anchor rods are prone to local instability during fixing, which gradually accumulates and affects the stress balance of the entire structure, reducing the load-bearing capacity of the structure and leading to overall structural failure. This causes uneven settlement of the foundation due to the anti-buoyancy anchor rods, resulting in wall cracking and structural damage. Therefore, it is inconvenient for construction personnel to use. Utility Model Content

[0030] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 An embodiment of this utility model provides a device for fixing and sealing post-construction anchor bolts, including a top plate 1, a pad 12 fixedly connected to the middle of the bottom end of the top plate 1, long strip anchor plates 8 fixedly connected to the bottom end of the top plate 1 near the edge, long grooves 9 fixedly connected to the opposite sides of the multiple long strip anchor plates 8, column anchor bolts 13 fixedly connected to the bottom left and right sides of the pad 12, upper barbs 16 fixedly connected to the upper middle part of the outer wall of the column anchor bolts 13, lower barbs 17 fixedly connected to the lower middle part of the outer wall of the column anchor bolts 13, a hollow block 10 connected to the middle of the bottom end of the pad 12, a grout leakage port 18 connected to the middle of the rear side of the hollow block 10, anchor bolts 11 fixedly connected to the bottom edge of the pad 12, a grouting pipe 4 connected to the right side of the outer wall of the hollow block 10, a sealing mechanism 2 provided at the middle of the top end of the top plate 1, the sealing mechanism 2 is used for sealing and stabilizing, and a bottom plate 15 fixedly connected to the bottom of the hollow block 10.

[0031] Specifically, the top plate 1 serves as the upper component of the entire structure, with long anchor plates 8 uniformly and securely fixed to its bottom edge. The long anchor plates 8 are tightly connected to the top plate 1 by welding and high-strength bolts 205. The long groove 9 has multiple functions; it provides installation for other connecting parts in the anchoring process and can be used to install positioning pins. The upper and lower parts of the outer wall of the column anchor rod 13 are respectively fixed with upper barbs 16 and lower barbs 17. Upper barbs 16 and lower barbs 17 are commonly used in column anchor rods 13. The main function of the hollow block 10 is to inject anchoring material. The anchor bolt 11 is fixed by a specific installation tool.

[0032] Please see the appendix Figure 1 and attached Figure 3 The sealing mechanism 2 includes a circular column 208. The bottom end of the circular column 208 is fixedly connected to the middle of the top end of the top plate 1. The top of the circular column 208 is fixedly connected to a column steel bar 202. The top of the circular column 208 is provided with a stainless steel cap 203. The bottom of the stainless steel cap 203 is fixedly connected to a sealing plate 206. The top of the stainless steel cap 203 is provided with a slot 204. The inner side of the slot 204 is fitted with a U-shaped block 201. The top left and right sides of the U-shaped block 201 are threadedly connected with bolts 205. The top of the top plate 1 is provided with a screw hole 207. The inner side of the screw hole 207 is threadedly connected to the bottom of the outer wall of the bolt 205. The outer wall of the top plate 1 is provided with a U-shaped suspension rod 5 near the edge. The outward side of the multiple U-shaped suspension rods 5 is fixedly connected with a connecting plate 6.

[0035] Specifically, the U-shaped hanger 5 is usually made of high-strength steel, and the U-shaped steel bar 7 is usually a square frame structure welded from four steel bars. Its material is matched with that of the U-shaped hanger 5 to ensure that the two have good synergistic performance. When the U-shaped hanger 5 and the U-shaped steel bar 7 are used together, in the concrete structure, the U-shaped hanger 5 penetrates into the concrete and transfers the load to the concrete through the bonding and anchoring effect with the concrete. The grouting pipe 4 is generally made of high-strength plastic pipe with a smooth inner wall to ensure the smooth flow of grout during the grouting process.

[0036] Working principle: First, connect the top plate 1 with the pad plate 12. Then, install the long anchor plate 8 and the column anchor rod 13 at the edge of the pad plate 12. Next, place the long anchor plate 8 and the column anchor rod 13 into the designated fixing hole. Then, fix the U-shaped hanger 5 with the connecting plate 6 and lay it on the surface of the top plate 1. Then, make contact with the U-shaped steel bar 7. After that, inject cement grout into the inside of the hollow block 10 through the grouting pipe 4, thereby stabilizing the column anchor rod 13 and the top plate 1. Therefore, it can effectively fix the rear-mounted anchor rod, avoid shaking, and improve stability.

[0037] At this point, the circular column 208 is connected to the column reinforcement 202. Then, the stainless steel cap 203 is fixed to the sealing plate 206 and attached to the surface of the top plate 1. The U-shaped block 201 is then engaged with the inner side of the slot 204. The bolt 205 is then turned to the inner side of the corresponding screw hole 207 to ensure the limit is reached. Finally, cement grout is applied to the surface of the U-shaped lifting bar 5, the U-shaped reinforcement 7, and the U-shaped block 201 to seal the area. This effectively achieves the sealing operation and meets the needs of the operator.
