Description

Technical Field

[0001] This utility model relates to the field of anti-buoyancy anchor technology, and in particular to an anti-buoyancy anchor structure for building construction. Background Technology

[0002] Anti-buoyancy anchors are a type of anti-buoyancy measure for underground structures in building engineering. Anti-buoyancy anchors are structural components installed to resist the upward displacement of structures above them. Their stress direction is related to the level and changes in groundwater, and is opposite to that of compression piles.

[0003] A post-reinforced anti-buoyancy anchor disclosed in Chinese patent CN222557625U uses concrete to lift the movable cover and the first movable insert plate, inserting them into the soil to enhance the stability of the anchor body. A push rod pushes four second insert rods, causing them to insert into the soil, further improving the stability below the reinforcement and increasing the anti-buoyancy performance of the anchor body. However, while solving the problem, this post-reinforced anti-buoyancy anchor has the following drawbacks:

[0004] Firstly, the first movable insert plate is fixedly connected to the movable cover, so the tilt angle of the first movable insert plate is fixed. Therefore, when the movable cover floats up, the first movable insert plate moves vertically upward, so the first movable insert plate cannot be inserted into the soil, thus failing to enhance the stability of the anchor body.

[0005] Secondly, at the beginning of concrete pouring, the amount of concrete is relatively small, resulting in less pressure on the chassis. This leads to insufficient thrust from the push rod to the second movable insert plate, causing the second movable insert plate to not have enough power to insert into the soil. As the concrete pouring continues, concrete will enter through the gap between the chassis and the bottom cone. The pressure of the concrete will also provide lift to the chassis, thus offsetting the pressure of the concrete above the chassis. This results in the second movable insert plate being unable to insert into the soil, or having a limited insertion size, leading to limited improvement in stability. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0007] Therefore, one objective of this utility model is to propose an anti-buoyancy anchor structure for building construction, which aims to solve the problem that post-reinforced anti-buoyancy anchors in the prior art are difficult to effectively improve the stability of the anchor body.

[0008] To achieve the above objectives, one embodiment of this utility model provides an anti-buoyancy anchor structure for building construction, including a base and a slide block. The slide block is slidably connected inside the base. Multiple steel bars are fixedly connected to the top of the inner wall of the base. An arc-shaped plate is fixedly connected between two adjacent steel bars. A swing arm is hinged to the bottom of the arc-shaped plate. A traction rod is fixedly connected to the center of the top of the slide block. A push rod is hinged to the outer surface of the traction rod. The end of the push rod away from the traction rod is hinged to one end of the swing arm. An exhaust hole is provided on the slide block. An air guide pipe is fixedly connected to the top of the slide block at a position corresponding to the exhaust hole.

[0009] The beneficial effects are:

[0010] Firstly, during the grouting process, the weight of all the cement mortar will press on the top of the sliding block, and the sliding block is slidably connected to the base. Thus, the sliding block can be subjected to sufficient pressure, causing the sliding block to slide downward in the base, driving the traction rod downward. The traction rod then pushes the swing arm through the push rod, causing the swing arm to unfold outward and insert into the soil. After the grouting and solidification are completed, the swing arm is located in the soil, which can enhance the stability of the anchor body.

[0011] Secondly, as the swing arm extends outward, the end of the swing arm moves in an arc, which can cut a fan-shaped groove in the soil. During the grouting process, the grout will enter the fan-shaped groove. After the grout solidifies, it will further increase the contact area between the anchor body and the soil, thereby further enhancing the stability of the anchor body.

[0012] Preferably, in any of the above embodiments, the traction rod is a hollow tube, and the outer surface of the traction rod has multiple through holes.

[0013] The beneficial effects are as follows: the hollow traction rod can be regarded as a high-pressure pipe, and the surface is provided with through holes, so it can replace the high-pressure grouting pipe. Therefore, there is no need to tie and fix the high-pressure grouting pipe separately, thus saving the use of high-pressure grouting pipe, reducing costs, and achieving the purpose of energy saving.

[0014] Preferably, in any of the above embodiments, two lifting lugs are fixedly connected to the outer surface of the top end of the traction rod.

[0015] The beneficial effect is that it facilitates the connection between the hook and the traction rod when hoisting the anti-buoyancy anchor rod, thereby facilitating the hoisting process.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

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 according to the specific circumstances.

[0024] This utility model provides an anti-buoyancy anchor structure for building construction.

[0025] Example 1:

[0026] like Figure 1 As shown, it includes a base 1 and a slide 2. The slide 2 is slidably connected inside the base 1. A sealing gasket is provided on the outer surface of the slide 2 to seal the gap between the slide 2 and the base 1, preventing cement mortar from entering between the slide 2 and the base 1. Multiple steel bars 11 are fixedly connected to the top of the inner wall of the base 1. The bottom end of the steel bars 11 limits the top of the slide 2, preventing the slide 2 from sliding upward out of the base 1. An arc-shaped plate 12 is fixedly connected between two adjacent steel bars 11. Please refer to [reference needed]. Figure 1 and Figure 2A connecting seat 13 is fixedly connected to the bottom of the inner wall of the arc-shaped plate 12. A swing arm 3 is hinged to the arc-shaped plate 12 through the connecting seat 13. A traction rod 21 is fixedly connected to the center of the top of the slide block 2. Please refer to [link / reference]. Figure 1 and Figure 3 A positioning seat 24 is fixedly connected to the outer surface of the traction rod 21. A push rod 4 is hinged to the traction rod 21 through the positioning seat 24, and the end of the push rod 4 away from the traction rod 21 is hinged to one end of the swing arm 3. When the traction rod 21 slides downward, the push rod 4 can push the swing arm 3 downward, causing the swing arm 3 to rotate around the connecting seat 13 until the swing arm 3 touches the arc plate 12. Figure 3 As shown, the slide block 2 is provided with an exhaust hole 22, which extends from the top to the bottom of the slide block 2. A duct pipe 23 is fixedly connected to the top of the slide block 2 at the position corresponding to the exhaust hole 22. The duct pipe 23 is tied to the traction rod 21 with wire. When the slide block 2 slides downward in the base 1, the air between the slide block 2 and the base 1 can be discharged upward through the exhaust hole 22 and the duct pipe 23. Two lifting lugs 26 are fixedly connected to the outer surface of the top end of the traction rod 21. When the anti-buoyancy anchor rod is placed into the borehole, the hoisting equipment can easily lift the device through the two lifting lugs 26.

[0027] The assembly process of this embodiment is as follows: First, slide the slide block 2 into the base 1. Then, weld the steel bar 11 to the top of the inner wall of the base 1 to limit the slide block 2. Next, weld and fix the traction rod 21 to the center of the top of the slide block 2. The arc plate 12 is welded between two adjacent steel bars 11. The arc plate 12 is provided with multiple layers. By rotating the slide block 2, the positioning seat 24 on the traction rod 21 is aligned with the connecting seat 13 on the arc plate 12. Then, the swing arm 3 is hinged to the connecting seat 13 by a pin. The push rod 4 is hinged to the positioning seat 24 by a pin. The ends of the push rod 4 and the swing arm 3 are hinged together by a pin. Finally, the air guide pipe 23 is welded to the top of the exhaust hole 22 to complete the assembly.

[0028] During construction, the hoisting equipment lifts the traction rod 21 upward through the two lifting lugs 26. The traction rod 21 pulls the slide block 2 upward, and the push rod 4 pulls the swing arm 3, so that the outer end of the swing arm 3 retracts towards the traction rod 21. After the slide block 2 slides upward and contacts the bottom end of the steel bar 11, it can drive the base 1 to rise synchronously. Then the anti-buoyancy anchor rod is vertically placed into the borehole.

[0029] Next, the atmospheric pressure grouting pipe and the high pressure grouting pipe are placed into the borehole. Grout is injected into the borehole through the atmospheric pressure grouting pipe. As grout is injected, the atmospheric pressure grouting pipe is pulled out upwards until the borehole is filled. During the grouting process, as the amount of cement mortar increases, the pressure on the slide block 2 will increase. Eventually, the weight of all the cement mortar will press on the slide block 2. The air between the slide block 2 and the base 1 is discharged to the outside through the exhaust hole 22 and the air guide pipe 23, so that the slide block 2 can slide down smoothly. Pull the traction rod 21. The traction rod 21 pulls the push rod 4 down. The push rod 4 presses down on the swing arm 3, and the swing arm 3 unfolds outwards and inserts into the soil. After the cement mortar solidifies, a second high pressure grouting can be performed through the high pressure grouting pipe.

[0030] Example 2:

[0031] like Figure 3 As shown, based on Embodiment 1, the traction rod 21 is a hollow tubular shape, and multiple through holes 25 are provided on the outer surface of the traction rod 21. The traction rod 21 can be used as a high-pressure grouting pipe. By connecting a delivery pipe to the top of the traction rod 21, high-pressure grouting operations can be carried out through the traction rod 21.
