Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to an anti-floating anchor rod construction structure. Background Art

[0002] Anti-floating anchor rods are a type of anti-floating measure for underground structures in construction projects. When the groundwater is shallow for large underground structures, such as open-air or underground swimming pools, large underground parking lots, large basements, etc., due to the large construction area of ​​the underground structure, deep foundation burial, and relatively few building floors, under the highest groundwater level in history, the deadweight of the structure is not enough to resist the buoyancy of the groundwater. Therefore, anti-floating anchor rods or anti-floating piles are usually used in the design, in which one end of the anti-floating anchor rod is anchored to the bottom plate of the building, and the other end is anchored to the bearing layer of the foundation of the building. The friction between the anchor steel bar and the grouting body and the surrounding soil layer is used to resist the buoyancy, thereby playing the anti-floating role of the anti-floating anchor rod.

[0003] At present, during the construction process of anti-floating anchor rods, it is often necessary to place the anti-floating anchor rods vertically in the drilled holes and then pour concrete. However, during the pouring process, it is very likely that the entire anchor rod will be tilted and offset, which has a great impact on the pouring quality and has poor durability during subsequent use. Summary of the invention

[0024] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] In the examples, unless otherwise specified, all the means used are conventional means in the art.

[0026] See also Figure 1-Figure 5 , an anti-floating anchor construction structure includes an anchor assembly 100 and a positioning assembly 200.

[0027] See also Figure 1 and 2 The anchor assembly 100 includes an anchor head 110 , an anchor reinforcement 120 and a connecting plate 130 . The anchor reinforcement 120 is disposed on the top of the anchor head 110 , and the connecting plate 130 is fixedly sleeved on the surface of the anchor reinforcement 120 .

[0028] Among them, an inclined piece 112 is arranged at the bottom of the anchor head 110, and the two inclined pieces 112 are perpendicular to each other. By arranging the inclined pieces 112 perpendicular to each other, it can be better inserted into the hole with a soft bottom, and insertion and positioning are convenient.

[0029] In a specific embodiment, the anchor steel bars 120 and the connection plates 130 are connected by welding, and a plurality of anchor steel bars 120 are symmetrically arranged.

[0030] See also Figure 1 , 2 , 3, 4 and 5, the positioning assembly 200 includes a rotating rod 210, a sleeve 220, an abutment rod 230 and an extrusion block 240, the bottom end of the rotating rod 210 is threadedly connected to the anchor head 110, the sleeve 220 is fixedly connected to the connecting plate 130, the abutment rod 230 slides through the sleeve 220, and the extrusion block 240 is fixedly connected to the rotating rod 210 and close to the abutment rod 230.

[0031] In this embodiment, the anchor head 110 is provided with a thread groove 111, and the end of the rotating rod 210 is provided with a thread head 211, and the thread head 211 and the thread groove 111 are threadedly connected. By arranging the thread head 211 and the thread groove 111 to be threadedly connected, when the rotating rod 210 is operated to rotate, the rotating rod 210 can drive the thread head 211 to rotate in the thread groove 111 and move axially.

[0032] The extrusion block 240 is conical and is fixedly sleeved on the surface of the extrusion block 240 . By setting the conical extrusion block 240 , when the rotating rod 210 rotates and moves axially, the extrusion block 240 is kept in contact with the extrusion abutment rod 230 .

[0033] Specifically, the abutment rod 230 is movably provided with a wedge block 231 , and the wedge block 231 is close to the extrusion block 240 . By arranging the wedge block 231 to contact the conical extrusion block 240 , the abutment rod 230 can be better extruded and pushed to move.

[0034] It should be noted that the sleeve 220 is rectangular, and the abutment rod 230 is matched with the sleeve 220 . The sleeve 220 with a rectangular design and the matched abutment rod 230 restrict the rotation of the abutment rod 230 .

By providing the fixing ring 212, it is convenient for personnel to operate the rotating rod 210 by rotating the fixing ring 212, thereby facilitating construction operations.

[0036] The working principle of the anti-floating anchor construction structure is as follows: during construction, the whole is placed vertically into the drilled hole, and the rotating rod 210 is operated to rotate by rotating the fixing ring 212. The rotating rod 210 drives the threaded head 211 at its end to rotate, and the threaded head 211 rotates and moves axially along the thread groove 111, and the rotating rod 210 also moves axially. The rotating rod 210 drives the extrusion block 240 to move, and the conical extrusion block 240 extrudes the wedge block 231, and the wedge block 231 pushes the abutment rod 230, and the abutment rod 230 slides along the sleeve 220. Multiple symmetrical abutment rods 230 support the entire anchor rod more stably in the hole, thereby avoiding the tilt of the anchor rod caused by pouring concrete to a large extent and improving the quality of the project.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods.
