Description

Technical Field

[0001] This invention relates to the field of anti-buoyancy anchor construction, specifically to a segmented anti-buoyancy anchor that is easy to construct and its installation method. Background Technology

[0002] With the development of the construction industry, anti-buoyancy anchors are widely used in various types of buildings to prevent underground structures from floating or being damaged due to excessive pressure in the basement, which would seriously affect the structural safety of the building. At the same time, since anti-buoyancy anchors are underground structures, the possibility of later maintenance is zero. Therefore, the structural safety and durability of anti-buoyancy anchors are extremely important. In addition, because anti-buoyancy anchors penetrate the waterproof layer, they are also weak points in the waterproofing structure. The effectiveness of the waterproofing nodes of anti-buoyancy anchors determines the effectiveness of the waterproofing of the entire underground structure.

[0003] Traditional anti-buoyancy anchors often use steel reinforcement to form a monolithic lattice steel frame. During construction, the entire frame is fabricated as a single unit, and after the bottom anchor holes are drilled, it is installed into the holes and then grouted to form the anchor body. After construction, all the bottom anchor reinforcement is exposed above ground. Traditional anchor construction results in a dense array of bottom anchors at the bottom of the pit, hindering the passage of small machinery and muck trucks, as well as the efficiency of foundation excavation and manual bottom cleaning. Furthermore, to facilitate passage during traditional anchor construction, one or more rows of bottom anchors are often temporarily bent to the ground. This method results in the reinforcement roots being bent before... Straightening the bottom anchor rod can easily lead to brittle fracture at the root of the bottom anchor rod, seriously affecting the structural safety of the bottom anchor rod. Exposed rebar is prone to bending and compression during construction, or mechanical collisions during construction, which can easily cause the bottom anchor rod's anchor body to crack, seriously affecting the durability of the bottom anchor rod. Traditional anti-buoyancy anchor rod construction is limited by the diameter of the anchor body, and usually multiple anchor rods are set to ensure connection, resulting in a large number of exposed rebars. The installation of waterstop rings and waterstop strips of traditional anti-buoyancy anchor rods is difficult, the waterproof joint treatment is more complicated, the structural reliability is poor, and a potential leakage risk is formed.

[0004] In existing technologies, traditional anti-buoyancy anchor rods have exposed reinforcing bars, which affects ground construction. During construction, the reinforcing bars are easily subjected to pressure or collision, affecting the safety and durability of the anchor rod structure. At the same time, traditional anti-buoyancy anchor rod waterproof joints have many exposed reinforcing bars, making the treatment more complicated. The waterproof joints have poor reliability and pose a serious risk of leakage. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a segmented anti-buoyancy anchor bolt and its installation method that is easy to construct. This solution has the advantages of high construction efficiency, reliable structure, and good waterproof effect. The segmented construction of the anchor bolt avoids the problem of exposed steel bars affecting construction.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a segmented anti-buoyancy anchor rod that is easy to construct, comprising several bottom anchor rods, an anchor body cast on the outer side of the bottom anchor rods, a transition piece provided at the top of the bottom anchor rods, a pad layer provided on the outer periphery of the transition piece, a connecting threaded hole I provided on the top surface of the transition piece, a transition anchoring structure threadedly connected to the connecting threaded hole I, a screw rod I provided at the bottom end of the transition anchoring structure for cooperating with the connecting threaded hole I, the length of the screw rod I being greater than the length of the connecting threaded hole I, a waterproof material I provided on the top surface of the transition piece and the pad layer, a waterproof membrane provided on the top surface of the waterproof material I, a second waterproof material provided on the top surface of the waterproof membrane, a waterproof sealing cover plate provided on the top surface of the second waterproof material, waterproof materials for connection provided on both the top and bottom surfaces of the waterproof membrane, and a tightening nut for tightening the waterproof sealing cover plate threadedly connected to the screw rod I.

[0007] In the above scheme, boreholes are drilled into the soil layer, and an anchor body is formed by pouring concrete to tightly connect several bottom anchor rods to the soil structure, providing anti-buoyancy. A transition piece is used for a detachable connection of the subsequent anchoring structure. A cushion layer is added to further enhance structural stability and protect the anchor body structure. The detachable connection is achieved through the threaded engagement of threaded hole one and screw one. The length of screw one is greater than the length of threaded hole one, allowing for a secondary tightening of screw one with a clamping nut after the initial tightening. A multi-layered waterproof structure is formed by waterproof material one, waterproof membrane, waterproof material two, and a waterproof sealing cover. The waterproof sealing cover is tightened by the clamping nut, ensuring the connection stability of the waterproof structure. The waterproof structure extends beyond the transition piece to prevent water seepage at the joints around the transition piece.

[0008] Furthermore, the anchor body is connected to the bottom of the adapter, and the adapter is set at the same height as the pad layer.

[0009] The anchor body and the adapter form an integral whole, resulting in a stable structure. The equal-height setting facilitates the construction of the waterproof structure. The padding layer is constructed on the upper side of the anchor body to reinforce and strengthen it.

[0010] Furthermore, the top surface of the adapter is provided with a plurality of threaded holes, and an adapter anchoring structure is connected to each of the threaded holes.

[0011] Multiple connecting threaded holes are provided to meet the connection requirements of multiple transition anchoring structures.

[0012] Furthermore, the adapter is provided with a rust-proof layer or is a rust-proof material processed part.

[0013] The adapter is equipped with a galvanized anti-rust layer to prevent the structure from rusting.

[0014] Furthermore, the bottom surface of the adapter is provided with a second threaded hole, and the top end of the bottom anchor rod is provided with a second screw that mates with the second threaded hole.

[0015] The threaded connection between the second threaded hole and the second threaded rod of the bottom anchor rod facilitates on-site assembly and construction, resulting in a short construction cycle and high efficiency.

[0016] Furthermore, the adapter has a mechanically roughened structure on its side.

[0017] The sides of the adapter are mechanically roughened to facilitate bonding with the bottom anchor bolt cement mortar and bedding layer after grouting, thus preventing leakage from the sides of the adapter.

[0018] Furthermore, the waterproof sealing cover is a concave steel plate with protrusions on all four sides, and a round hole is provided in the middle of the waterproof sealing cover for mating with the screw.

[0019] The diameter of the round hole in the waterproof sealing cover matches the diameter of the screw rod, and the protrusions around the perimeter facilitate the clamping of the waterproof membrane and the adapter.

[0020] An installation method for the above-mentioned easy-to-construct segmented anti-buoyancy anchor bolt includes the following steps:

[0021] S1. Install adapters at the top of several bottom anchor bolts, install temporary plugs in the connecting threaded holes of the adapters, place the bottom anchor bolts in the drill holes, and perform bottom anchor bolt grouting.

[0022] S2. Pour the foundation layer, with the top surface of the foundation layer flush with the top surface of the transition piece;

[0023] S3. Apply waterproof material to the top and outer surfaces of the adapter and lay the waterproof membrane. Then remove the temporary plug, apply waterproof material two to the top surface of the waterproof membrane, and install the waterproof sealing cover.

[0024] S4. A pre-set clamping nut is installed on screw one. The adapter anchoring structure is installed by threadedly engaging screw one with the threaded hole of the adapter. After screw one is tightened, the clamping nut is rotated to lock it in place.

[0025] In the above scheme, step S1 involves setting up a transition piece to facilitate the installation of the subsequent transition anchoring structure. A temporary plug is installed at the top to prevent clogging of the connecting threaded hole one during anchor grouting and bedding layer cleaning. Grouting and curing are carried out by drilling holes in the ground, and the bottom anchor is fixedly connected to the drilled holes. In step S2, the top surface of the transition piece is cleaned of soil and laitance. A bedding layer is poured to protect and reinforce the bottom anchor and grouting structure. The top surface is flush to facilitate the application of waterproofing measures. In step S3, waterproofing material is applied. After the waterproofing material is applied, waterproof membrane is laid. The temporary plug is removed to avoid affecting the cover plate installation. A second layer of waterproofing material is applied, and a waterproof sealing cover plate is installed to waterproof the structural surface. In step S4, the transition anchoring structure is fixed by tightening the screw one with the connecting threaded hole one. The waterproof sealing cover plate is rotated to compact the gap between the waterproof membrane, waterproofing material and the transition piece, achieving effective waterproofing. The use of a transition anchoring structure during later installation facilitates foundation excavation and manual bottom cleaning, while tightening the nuts to compact the waterproof structure improves its waterproofing effect. Anchor hooks can be installed on the transition anchoring structure.

[0026] Furthermore, in step S1, after the temporary plug is installed, a temporary protective cap is set on the temporary plug. In step S3, the temporary protective cap is removed first, and then waterproof material is applied.

[0027] Temporary protective caps are installed to protect the temporary plug and its surrounding area, preventing the temporary plug from being deformed by impact and preventing it from being affected by grouting and bedding layer cleaning. The protective top temporary plug can be rotated and removed normally after grouting.

[0028] Furthermore, in step S3, when laying the waterproof membrane, a hole is made in the waterproof membrane at the temporary plug position, and the top temporary plug is removed after the hole is made.

[0029] By removing the temporary plug through the corresponding opening, the pore size of the waterproof membrane was ensured to be appropriate, thus avoiding any impact on the waterproofing effect.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. A segmented construction approach for anti-buoyancy anchors is provided. During construction, the elevation of the top surface of the transition piece is controlled to be consistent with the elevation of the top layer. The work during foundation excavation and manual bottom cleaning is as smooth as walking on flat ground, which greatly reduces the difficulty of foundation excavation and manual bottom cleaning, facilitates the passage of manual and mechanical personnel, and improves construction efficiency. The transition anchoring structure is installed in the later stage of construction, which greatly reduces the impact of pressure and collision and improves the reliability of the structure.

[0032] 2. At the same time, this invention patent solves the problem of low efficiency in the treatment of waterproof joints of traditional anti-buoyancy anchor rods. The segmented anti-buoyancy anchor rod is not affected by the diameter of the anchor body. By setting the transition piece, the number of exposed steel bars is reduced. One transition anchor structure replaces the original multiple stressed steel bars, which greatly reduces the number of waterproof joints, facilitates the treatment of waterproof joints, improves construction efficiency, and reduces the risk of leakage.

[0033] 3. By setting up waterproof sealing covers, tightening nuts, and applying two layers of waterproof sealant, the waterproof membrane is reinforced at the anti-buoyancy anchor points, improving the waterproofing effect and significantly increasing the efficiency and reliability of waterproofing.

[0046] Example 1

[0047] like Figure 1-9 As shown, a segmented anti-buoyancy anchor bolt that is easy to construct includes several bottom anchor bolts 2. An anchor body 10 is cast on the outer side of each bottom anchor bolt 2. A transition piece 1 is provided at the top of each bottom anchor bolt 2. A pad layer 11 is provided on the outer periphery of the transition piece 1. A connecting threaded hole 101 is opened on the top surface of the transition piece 1. A transition anchoring structure 5 is threadedly connected to the connecting threaded hole 101. A screw 501 for mates with the connecting threaded hole 101 is provided at the bottom end of the transition anchoring structure 5. The length of the screw 501 is greater than the length of the connecting threaded hole 101. The top surface of the adapter 1 and the pad 11 is provided with waterproof material 1. The top surface of the waterproof material 1 is provided with waterproof membrane 6. The top surface of the waterproof membrane 6 is provided with waterproof material 2. The top surface of the waterproof material 2 is provided with waterproof sealing cover 7. The top and bottom surfaces of the waterproof membrane 6 are both provided with waterproof material for connection. The screw 501 is threaded with a clamping nut 8 for clamping the waterproof sealing cover 7.

[0048] In the above scheme, by drilling holes in the soil layer and casting to form an anchor body 10, several bottom anchor rods 2 are tightly connected to the soil structure to provide anti-buoyancy. A transition piece 1 is used to facilitate the detachable connection of the subsequent anchoring structure 5. A pad layer 11 is installed to further enhance structural stability and protect the anchor body 10 structure. The detachable connection is achieved through the threaded engagement of the connecting threaded hole 101 and the screw rod 501. The length of the screw rod 501 is greater than the length of the connecting threaded hole 101, so after the initial tightening of the connecting threaded hole 101 and the screw rod 501, a second tightening is performed by rotating the screw rod 501 and the clamping nut 8. A multi-layered waterproof structure is formed by setting up waterproof material one, waterproof membrane 6, waterproof material two, and a waterproof sealing cover plate 7 for waterproofing. The clamping nut 8 presses the waterproof sealing cover plate 7, thereby ensuring the connection stability of the waterproof structure. The area of ​​the waterproof structure is larger than the area of ​​the transition piece 1 to prevent water seepage at the connection seams around the transition piece 1. Anchor hooks are installed on the transition anchoring structure 5.

[0049] The adapter 1 is configured according to the diameter of the anchor body 10 and the number of bottom anchor rods 2. The common size of the anchor body 10 is 150mm-200mm. The adapter 1 has connecting threaded holes at the top and bottom. The connecting threaded holes 101 and 102 are mechanically threaded. The opening size and depth of the connecting threaded hole 101 are selected according to the design load-bearing requirements of the high-strength screw rod. The opening size and depth of the connecting threaded hole 102 are selected according to the design load-bearing requirements of the bottom anchor rod 2. The top of the bottom anchor rod 2 is mechanically threaded and mechanically connected to the connecting threaded hole 102 on the adapter 1. The top of the screw rod 501 has a hook structure designed according to specifications and is mechanically threaded and mechanically connected to the connecting threaded hole 101 on the adapter 1. The high-strength screw rod is not installed during anchor rod construction and is installed after construction is completed to avoid affecting the construction.

[0050] Waterproofing materials one and two are fluid waterproof sealant 9, which can be polyurethane sealant. Bottom anchor 2 is an anchoring steel reinforcement structure. Screw 1 501 is a high-strength adapter screw. Waterproof sealant 9 is applied to the top surface of adapter 1 and its outer 100mm radius. Screw 1 501 and Screw 2 201 are high-strength screws. The length of connecting threaded holes 101 and 102 is not less than 50mm. Bottom anchor 2 is arranged in a circular pattern, with three anchors at equal angles.

[0051] Furthermore, the anchor body 10 is connected to the bottom of the adapter 1, the adapter 1 is set at the same height as the pad 11, and the pad 11 is located on the upper side of the anchor body 10.

[0052] The anchor body 10 and the adapter 1 form an integral whole, with a stable structure. The equal height setting facilitates the construction of the waterproof structure. The pad layer 11 is constructed on the upper side of the anchor body 10 to reinforce and strengthen the anchor body 10.

[0053] Furthermore, the adapter 1 is provided with a rust-proof layer or is a rust-proof material processed part.

[0054] The adapter 1 is provided with a galvanized anti-rust layer to prevent the structure from rusting.

[0055] Furthermore, the bottom surface of the adapter 1 is provided with a connecting threaded hole 102, and the top end of the bottom anchor rod 2 is provided with a screw 201 that mates with the connecting threaded hole 102.

[0056] The threaded connection between the threaded hole 102 and the screw 201 of the bottom anchor rod 2 facilitates on-site assembly and construction, resulting in a short construction cycle and high efficiency.

[0057] Furthermore, the adapter 1 has a mechanically roughened structure 103 on its side.

[0058] The sides of the adapter 1 are mechanically roughened to facilitate bonding with the cement mortar of the bottom anchor rod 2 and the pad layer 11 after grouting, thus preventing leakage from the sides of the adapter 1.

[0059] Furthermore, the waterproof sealing cover 7 is a concave steel plate with protrusions on all four sides, and a round hole is provided in the middle of the waterproof sealing cover 7 for cooperating with the screw 501.

[0060] The diameter of the round hole in the waterproof sealing cover plate 7 matches the diameter of the screw 501, and the protrusions on all sides facilitate the clamping of the waterproof membrane 6 and the adapter 1.

[0061] The waterproof sealing cover plate 7 is a circular plate. Waterproof material is applied to the top of the waterproof membrane 6 with the connection threaded hole 101 as the center and the radius of the waterproof sealing cover plate 7 as the radius. The waterproof sealing cover plate 7 and the gasket 12 are installed in alignment with the connection threaded hole 101. After tightening the screw 501, the tightening nut 8 is rotated to compact the gap.

[0062] An installation method for the above-mentioned easy-to-construct segmented anti-buoyancy anchor bolt includes the following steps:

[0063] S1. Set a connector 1 at the top of several bottom anchor rods 2, install a temporary plug 3 in the connecting thread hole 101 of the connector 1, place the bottom anchor rod 2 in the drill hole, and grout the bottom anchor rod 2.

[0064] S2. Pour the foundation layer 11, with the top surface of the foundation layer 11 flush with the top surface of the adapter 1.

[0065] S3. Apply waterproof material to the top and outer surface of the adapter 1 and lay the waterproof membrane 6. Then remove the temporary plug 3, apply waterproof material 2 to the top surface of the waterproof membrane 6, and install the waterproof sealing cover 7.

[0066] S4. A pre-set clamping nut 8 is installed on the screw 501. The adapter anchoring structure 5 is installed by threadedly engaging the screw 501 with the threaded hole 101 of the adapter 1. After the screw 501 is tightened, the clamping nut 8 is rotated to lock it in place.

[0067] In the above scheme, in step S1, the adapter 1 is set up to facilitate the installation of the subsequent anchoring structure 5. A temporary top plug 3 is installed to prevent blockage of the connecting threaded hole 101 during anchor grouting and cleaning of the bedding layer 11. Grouting and curing are carried out by drilling holes in the ground, and the bottom anchor 2 is fixedly connected to the drilled holes. In step S2, the top surface of the adapter 1 is first cleaned of soil and laitance. The bedding layer 11 is poured to protect and reinforce the bottom anchor 2 and the grouting structure. The top surface is flush to facilitate waterproofing measures. In step S3, a waterproofing material is applied. After the waterproofing material is applied, the waterproof membrane 6 is laid. The temporary plug 3 is removed to avoid affecting the cover plate installation. A second layer of waterproofing material is applied, and the waterproof sealing cover plate 7 is installed to waterproof the structural surface. In step S4, the adapter anchoring structure 5 is fixed by tightening the screw 501 with the connecting threaded hole 101. By rotating the tightening nut 8, the waterproof sealing cover plate 7 compacts the gap between the waterproof membrane 6, the waterproofing material, and the adapter 1, achieving effective waterproofing. The subsequent installation of the adapter anchoring structure 5 facilitates foundation excavation and manual bottom cleaning. The compaction of the waterproof structure by the tightening nut 8 improves the waterproofing effect.

[0068] Furthermore, in step S1, after the temporary plug 3 is installed, a temporary protective cap 4 is set on the temporary plug 3. In step S3, the temporary protective cap 4 is removed first, and then waterproof material is applied.

[0069] A temporary protective cap 4 is installed to protect the temporary plug 3 and its surrounding area, preventing the temporary plug 3 from being deformed by impact and affecting the use of the connecting threaded hole 101, and preventing the temporary plug 3 and threaded hole 1 from being affected during grouting and cleaning of the bedding layer 11. The protective top temporary plug 3 can be rotated and removed normally after grouting construction.

[0070] The temporary plug 3 is a bolt structure, and the temporary protective cap 4 is a rubber cap. The bottom has an installation hole corresponding to the shape of the temporary plug 3. The two are connected by a snap-fit. After the hole is opened, the top temporary plug 3 can be removed with a wrench and recycled.

[0071] Furthermore, in step S3, when the waterproof membrane 6 is laid, a hole is made in the waterproof membrane 6 at the position of the temporary plug 3, and the top temporary plug 3 is removed after the hole is made.

[0072] By removing the temporary plug 3 through the corresponding opening, the size of the pores in the waterproof membrane 6 was ensured to be appropriate, thus avoiding any impact on the waterproofing effect.
