Description

Technical Field

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

[0002] Anti-buoyancy anchors are a type of anchoring facility used in building engineering, especially in underground structure construction, to resist the buoyancy of groundwater. Anti-buoyancy anchors are typically anchored at one end to the building's base slab and at the other end to a stable soil or rock layer in the foundation. Through the interaction between the anchor body and the grouting body, the anti-buoyancy anchor transmits the pull-out force to the grouting body. Then, through the friction between the grouting body and the surrounding soil layers, the force is transmitted to the surrounding stable soil, forming a component with a certain pull-out resistance to achieve the anti-buoyancy effect.

[0003] Currently, in building construction, multiple anchor bolts are installed to effectively disperse the buoyancy and other upward forces generated by groundwater and increase the overall stability of underground structures. However, the connection between the installation structures of multiple anchor bolts is unstable, and the anchor bolts are prone to movement, affecting their anti-buoyancy capacity. Utility Model Content

[0004] To improve the stability of anchor installation, this application provides an anti-buoyancy anchor installation structure for basements.

[0005] This application provides a basement anti-buoyancy anchor installation structure, which adopts the following technical solution:

[0006] A basement anti-buoyancy anchor installation structure includes multiple anchors, with connectors provided between the anchors. The anchors are distributed circumferentially along the connectors, and the anchors are welded to the connectors. The number of connectors is multiple, and they are distributed along the length of the anchors.

[0007] By adopting the above technical solution, the anchor bolts are connected by connectors, which strengthens the connection between the anchor bolts, reduces the possibility of anchor bolt movement, and improves the stability of anchor bolt installation.

[0008] Optionally, the number of anchor bolts is three, and they are distributed in a triangular pattern at equal intervals along the outer circumference of the connector.

[0009] By adopting the above technical solution, the three anchor rods form a relatively stable triangular structure, which evenly disperses and balances the buoyancy of groundwater and other upward forces, provides structural stability, reduces the possibility of uneven uplift caused by groundwater pressure, and improves the structural stability of the anchor rod installation.

[0010] Optionally, a waterproof component is provided on the outside of the anchor rod, the waterproof component is located between the base plate and the foundation, the waterproof component has an anchor insertion port, and the anchor rod is inserted into the anchor insertion port.

[0011] By adopting the above technical solutions, the waterproof components can effectively isolate groundwater and moisture, reduce the penetration of water into the contact surface between the anchor rod and the soil, reduce the risk of corrosion of the anchor rod due to long-term contact with water, and thus improve the durability and stability of the anchor rod.

[0012] Optionally, a waterproof collar is connected to the top of the waterproof component, and the waterproof collar is filled with water-swellable cement, with the anchor rod inserted into and fixed to the water-swellable cement.

[0013] By adopting the above technical solutions, the waterproof sleeve provides a sealed environment for the installation of the anchor rod, reducing the possibility of moisture directly contacting the anchor rod, thereby reducing the risk of anchor rod corrosion and improving the durability of the anchor rod; the water-swellable cement increases in volume when it comes into contact with water, which can fill the gap between the anchor rod and the surrounding soil, providing a better sealing effect. At the same time, it can fix the anchor rod more tightly in the soil, improving the anchoring force of the anchor rod.

[0014] Optionally, a sleeve is provided on the outside of the anchor rod, and the anchor rod is inserted into the sleeve.

[0015] By adopting the above technical solution, when anchor bolts need to be installed in easily collapsible soil layers, the sleeve fitting is installed in the soil layer, and the anchor bolt is then inserted into the sleeve fitting. The sleeve fitting provides a solid external protection for the installation of the anchor bolt, enhances the lateral support of the anchor bolt, reduces the possibility of displacement or bending of the anchor bolt due to unstable soil layers, and improves the stability of the anchor bolt installation.

[0016] Optionally, one end of the anchor rod is bent, and a rib is connected to the bent part of the anchor rod, the length direction of the rib being perpendicular to the length direction of the anchor rod.

[0017] By adopting the above technical solution, when installing the anchor rod, the anchor rod is inserted into the foundation perpendicular to the ground level, and the length direction of the pin is perpendicular to the length direction of the anchor rod, so that the pin is anchored horizontally, providing a uniformly distributed horizontal support force for the installation of the anchor rod and improving the pull-out resistance of the anchor rod.

[0018] Optionally, a positioner is connected to the outside of the anchor bolt.

[0019] By adopting the above technical solution, the anchor bolts are placed in the accurate position required by the design during installation, reducing the possibility of deviation in the installation position of the anchor bolts. At the same time, the accurate position of the anchor bolts helps them to better perform their structural support function and enhance the stability of the overall structure.

[0020] Optionally, a reinforcing member is provided between the adjacent connecting members, and a clamping member is slidably provided on the reinforcing member. The anchor rod is inserted between the reinforcing member and the clamping member, and the clamping member is used to clamp all the anchor rods to the reinforcing member.

[0021] By adopting the above technical solution, the position of the anchor bolt is fixed, reducing the possibility of the anchor bolt moving during construction and further improving the stability of the anchor bolt installation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Connect the anchor bolts using connectors to enhance the connection between them, reduce the possibility of anchor bolt movement, and improve the stability of anchor bolt installation;

[0024] 2. The three anchors form a relatively stable triangular structure, which evenly distributes and balances the buoyancy of groundwater and other upward forces, providing structural stability, reducing the possibility of uneven uplift caused by groundwater pressure, and improving the stability of the anchor installation structure.

[0025] 3. When anchor bolts need to be installed in easily collapsible soil layers, the sleeve fitting is installed in the soil layer, and the anchor bolt is then inserted into the sleeve fitting. The sleeve fitting provides a sturdy external protection for the anchor bolt installation, enhances the lateral support of the anchor bolt, reduces the possibility of the anchor bolt shifting or bending due to soil instability, and improves the stability of the anchor bolt installation.

[0033] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0034] Reference Figure 1 The foundation 1 has anchor holes 11. When the anchor rod 3 is installed, the anchor rod 3 is inserted into the anchor holes 11, and a part of the anchor rod 3 protrudes from the foundation 1 and is anchored in the base plate 2.

[0035] This application discloses an anti-buoyancy anchor installation structure for a basement.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A basement anti-buoyancy anchor installation structure includes multiple anchor rods 3. One end of the anchor rod 3 is bent at a right angle. The anchor rod 3 is vertically inserted into the anchor hole 11 of the foundation 1. The bent end of the anchor rod 3 is anchored in the base plate 2. Connectors 4 are provided between the anchor rods 3. The anchor rods 3 are distributed circumferentially along the connectors 4. The sidewall of the anchor rod 3 is welded to the sidewall of the connector 4. There are multiple connectors 4, which are distributed along the length of the anchor rod 3. In this embodiment, the connectors 4 are made of steel pipes.

[0038] When anchoring the anchor rod 3, the anchor rod 3 is vertically inserted into the anchor hole 11 of the foundation 1, and grout is injected into the anchor hole 11 to fix the anchor rod 3 in the anchor hole 11. One bent end of the anchor rod 3 is anchored to the base plate 2. All the anchor rods 3 inserted into the base are connected by the connector 4 to enhance the connection between the anchor rods 3, reduce the possibility of the anchor rods 3 moving during construction, and improve the installation stability of the anchor rods 3.

[0039] The number of anchor rods 3 is three, and they are distributed in a triangular pattern at equal intervals along the outer circumference of the connector 4. The bending direction of the anchor rods 3 is towards the end away from the connector 4. The anchor rods 3 form a stable triangular structure, which evenly disperses and balances the buoyancy of groundwater and other upward forces, provides structural stability, reduces the possibility of uneven floating caused by groundwater pressure, and improves the structural stability of the anchor rod 3 installation.

[0040] One end of the anchor rod 3 is bent, and a shank 5 is connected to the bend of the anchor rod 3. The length direction of the shank 5 is perpendicular to the length direction of the anchor rod 3.

[0041] When installing the anchor rod 3, the anchor rod 3 is inserted into the foundation 1 perpendicular to the ground surface. The length direction of the pin 5 is perpendicular to the length direction of the anchor rod 3, so that the pin 5 is anchored horizontally, providing a uniformly distributed horizontal support force for the installation of the anchor rod 3 and improving the pull-out resistance of the anchor rod 3.

[0042] A locator 6 is connected to the outside of the anchor rod 3. The locator 6 and the connecting member 4 are distributed at intervals. The locator 6 includes a fixing member 61 and a positioning member 62. The two ends of the fixing member 61 and the positioning member 62 are fixed together. The positioning member 62 is trapezoidal with the fixing member 61 as the base. The positioning members 62 are distributed equidistantly along the outer wall of the fixing member 61. The anchor rods 3 are distributed equidistantly along the outer wall of the fixing member 61. The fixing member 61 is fixedly connected to the anchor rod 3. The diameter of the circle formed by the outer walls of all the positioning members 62 is larger than the diameter of the circle formed by all the anchor rods 3. The positioning members 62 and the anchor rods 3 are distributed at intervals.

[0043] When the locator 6 is installed, the anchor rods 3 are installed at equal intervals on the outer wall of the fixing member 61, and the locating member 62 is inserted between adjacent anchor rods 3. The two ends of the locating member 62 are welded and fixed to the fixing member 61. When the anchor rod 3 is inserted into the anchor hole 11, the outer wall of the locating member 62 abuts against the hole wall of the anchor hole 11, thereby guiding the insertion direction of the anchor rod 3, reducing the possibility of the anchor rod 3 deviating from the insertion direction, improving the accuracy of the anchor rod 3 installation, and thus enabling the anchor rod 3 to better play its structural support role and enhance the stability of the overall structure.

[0044] An anchor rod 3 is connected to a waterproof component 7 on its outer side. The waterproof component 7 is located between the base plate 2 and the foundation 1. The top and bottom walls of the waterproof component 7 are connected to the base plate 2 and the foundation 1, respectively. The waterproof component 7 has an anchor insertion port 71, which is concentric with the anchor hole 11. All anchor rods 3 are inserted into the anchor insertion port 71 and the anchor hole 11 in sequence. In this embodiment, the waterproof component 7 is made of waterproof membrane.

[0045] After the anchor rod 3 is anchored in the anchor hole 11, the waterproof component 7 is fitted into the anchor rod 3, the anchor rod 3 is inserted into the anchor insertion port 71, and the waterproof component 7 is tightly attached to the top wall of the foundation 1. The bottom wall of the base plate 2 is connected to the top wall of the waterproof component 7. The waterproof component 7 isolates groundwater and moisture, reduces the penetration of water into the contact surface between the anchor rod 3 and the soil, reduces the risk of corrosion of the anchor rod 3 due to long-term contact with water, and thus improves the durability and stability of the anchor rod 3.

[0046] A waterproof collar 72 is fixedly connected to the top of the waterproof component 7. The waterproof collar 72 is located at the anchor insertion port 71. The anchor rod 3 is inserted into the waterproof collar 72 and the anchor insertion port 71 in sequence. The waterproof collar 72 is filled with water-swellable cement 73. The anchor rod 3 is inserted into and fixed to the water-swellable cement 73.

[0047] After the waterproof component 7 is installed, the waterproof sleeve 72 is fitted onto the anchor rod 3. There is a gap between the waterproof sleeve 72 and the anchor rod 3. Water-swellable cement 73 is filled into the waterproof sleeve 72. When the water-swellable cement 73 comes into contact with water, its volume increases, which can fill the gap between the anchor rod 3 and the surrounding soil, providing a better sealing effect. At the same time, it can fix the anchor rod 3 more tightly in the soil, improving the anchoring force of the anchor rod 3.

[0048] The implementation principle of Embodiment 1 of this application is as follows: When anchoring the anchor rod 3, the anchor rod 3 is inserted into the anchor hole 11 of the foundation 1. The positioning component 62 abuts against the wall of the anchor hole 11, thereby positioning the installation position of the anchor rod 3. The anchor rod 3 insertion operation is stopped when the insertion end of the anchor rod 3 reaches the design depth. Grouting liquid is injected into the anchor hole 11 to fix the anchor rod 3 in the anchor hole 11. A waterproof component 7 is installed on the top wall of the foundation 1. The anchor rod 3 is inserted into the insertion port 71 to isolate groundwater and moisture, reduce water penetration to the contact surface between the anchor rod 3 and the soil, and reduce the anchor rod 3 from long-term contact with water. To mitigate the risk of corrosion, a waterproof collar 72 is installed on the top wall of the waterproof component 7. The anchor rod 3 is inserted into the waterproof collar 72, and water-swellable cement 73 is filled inside the waterproof collar 72. The water-swellable cement 73 increases in volume when in contact with water, which can fill the gap between the anchor rod 3 and the surrounding soil, fixing the anchor rod 3 more tightly in the soil and improving the anchoring force of the anchor rod 3. The end of the anchor rod 3 that is bent away from the foundation 1 is anchored to the base plate 2. All the anchor rods 3 inserted into the base are connected by connectors 4 to enhance the connection between the anchor rods 3, reduce the possibility of the anchor rods 3 moving during construction, and improve the installation stability of the anchor rods 3.

[0049] Example 2

[0050] Reference Figure 2 An anchor rod 3 is provided with a sleeve 8 on its outer side. The outer wall of the sleeve 8 fits against the inner wall of the anchor hole 11. All anchor rods 3 are inserted into the sleeve 8.

[0051] The implementation principle of Embodiment 2 of this application is as follows: When the anchor rod 3 is installed in a soil layer prone to collapse, the sleeve 8 is inserted into the anchor hole 11. The outer wall of the sleeve 8 fits against the hole wall of the anchor hole 11. The anchor rod 3 is then inserted into the sleeve 8. The sleeve 8 provides a solid external protection for the installation of the anchor rod 3, enhances the lateral support of the anchor rod 3, reduces the possibility of displacement or bending of the anchor rod 3 due to the instability of the soil layer, and improves the stability of the anchor rod 3 installation.

[0052] Example 3

[0053] Reference Figure 3A reinforcing member 9 is provided between adjacent connecting parts 4. The reinforcing member 9 is located within the space enclosed by the positioning part 62. The top wall of the reinforcing member 9 has a reinforcing groove 91, and the reinforcing groove 91 is equidistantly located on the periphery of the reinforcing member 9. The anchor rod 3 is inserted into the reinforcing groove 91. The groove wall of the reinforcing groove 91 is fitted with the outer wall of the anchor rod 3. The groove wall of the reinforcing groove 91 has a sliding groove 911. The reinforcing member 9 is slidably provided with a clamping member 92, which is inserted into the sliding groove 911. The anchor rod 3 is inserted between the reinforcing member 9 and the clamping member 92. The clamping member 92 is used to clamp all the anchor rods 3 to the reinforcing member 9. The top wall of the clamping member 92 has a clamping groove 921, and the groove wall of the clamping groove 921 is fitted with the outer wall of the anchor rod 3 to fix the position of the anchor rod 3, reduce the possibility of the anchor rod 3 shifting position, and further improve the stability of the anchor rod 3 installation.

[0054] The implementation principle of Embodiment 3 of this application is as follows: Before installing the locator 6, the anchor rod 3 is inserted into the fixing groove, the clamping member 92 is installed, the clamping member 92 is inserted into the sliding groove 911, the clamping member 92 slides, the groove wall of the clamping groove 921 fits against the anchor rod 3, the clamping member 92 clamps the anchor rod 3 in the reinforcement member 9, and then the clamping member 92 and the reinforcement member 9 are welded to fix the position of all anchor rods 3, reduce the possibility of the anchor rod 3 moving during construction, and improve the stability of the anchor rod 3 installation.
