During the manufacturing process of in-situ concrete piles, the floating of the reinforcing cage represents a frequent, technically demanding challenge. The floating of the reinforcing cage not only impairs the load-bearing capacity of the pile foundation, but frequently requires repair work of the project, which leads to construction delays, additional work and economic losses.In the prior art, floating of the reinforcing cage is prevented by increasing its weight. However, increasing the weight of the reinforcing cage increases the difficulties of construction and the costs.In view of this, it is necessary to propose an anchor device for preventing the floating of reinforcing cages in order to increase the construction efficiency, reduce the cost and ensure the stability of the reinforcing cage.Content of the Utility ModelThe present invention relates to an anchor device for preventing the floating of reinforcing baskets. The present invention solves the technical problem in the prior art, in which floating is prevented by increasing the weight of the reinforcing cage, but this leads to increased construction costs and process difficulties.To achieve this object, the present invention proposes an anchor device for preventing the floating of reinforcing baskets. The anchoring device comprises a reinforcing cage, wherein the reinforcing cage comprises longitudinal steels and reinforcing bars. The anchoring device further comprises: a support rod, the support rod connecting the reinforcing cage; a pressure plate, the pressure plate being movably disposed on the support rod, and the pressure plate being disposed within the reinforcing cage; anti-floating rods, ends of the anti-floating rods being rotatably connected to the pressure plate; bottom rods, the bottom rods being disposed on the support rod; and slant rods, ends of the slant rods being rotatably connected to the bottom rods, and the other ends of the slant rods being rotatably connected to the anti-floating rods.In some embodiments, the anchoring device further comprises cone tips, the cone tips being located at other ends of the anti-floating rods, and the cone tips facilitating penetration of the anti-floating rods into the ground.In some embodiments, the anchoring device further comprises a multiaxial connecting socket, wherein a first bushing for connecting to the support rod is arranged on the multiaxial connecting socket, and second bushings for connecting to the bottom rods are arranged on the multiaxial connecting socket.In some embodiments, a plurality of second bushings are provided, and the plurality of second bushings are circumferentially spaced at a lower end of the first bushing.In some embodiments, the anchoring device further comprises: pivot axis parts, the pivot axis parts being disposed at a bottom of the pressure plate; and pivot axis holes, the pivot axis holes being disposed at the ends of the anti-floating rods.In some embodiments, the anchoring device further comprises a limiting part, wherein the limiting part is arranged at an upper end of the support rod.The present invention provides the anchor device for preventing the floating of reinforcing baskets.

When concreting the borehole, the concrete is introduced in the direction of the pressure plate inside the reinforcing cage. In this case, the concrete hits the pressure plate and causes the pressure plate to move downward. Due to the limitation by the pressure plate and the inclined rods, during the downward movement of the pressure plate, the anti-floating rods are driven to rotate into the outer space of the reinforcing cage. This allows the anti-floating rods to penetrate the surrounding bottom layer or rock layer of the borehole and achieve an anchoring effect. At the same time, a downward pressure is applied to the reinforcing cage in order to prevent the reinforcing cage from floating.DESCRIPTION OF THE ACCOMPANYING DRAWINGSIn order to more clearly explain the technical solutions in the embodiments of the present invention or in the prior art, the drawings required for describing the embodiments or the prior art will be briefly presented below.

The anchor device further comprises: a support rod 4, the support rod 4 connecting the reinforcing cage; a pressure plate 3, the pressure plate 3 being movably disposed on the support rod 4, and the pressure plate 3 being disposed inside the reinforcing cage; anti-floating rods 7, ends of the anti-floating rods 7 being rotatably connected to the pressure plate 3; bottom rods 6, the bottom rods 6 being disposed on the support rod 4; and slant rods 8, ends of the slant rods 8 being rotatably connected to the bottom rods 6, and the other ends of the slant rods 8 being rotatably connected to the anti-floating rods 7.Here, the reinforcing bars 2 are welded to a plurality of longitudinal steels 1 arranged at intervals on the circumferential side in order to form a reinforcing cage. The reinforcing cage has an inner space and an outer space. The reinforcing cage must be placed in the well and concrete then poured into the well to form a cast-in-place concrete pile. The support rod 4 is located in the inner space of the reinforcing cage and the support rod 4 is parallel to the longitudinal bars 1 to improve the pile forming effect.In this case, a matching through bore for the support rod 4 is provided on the pressure plate 3, and the pressure plate 3 is movably mounted on the support rod 4. Due to the limitation by the pressure plate 3 and the inclined rods 8, during the downward movement of the pressure plate 3 the anti-floating rods 7 are driven to rotate into the outer space of the reinforcing cage so that the anti-floating rods 7 can enter the surrounding bottom layer 11 of the borehole.Specifically, when concreting the borehole, the concrete is introduced in the direction of the pressure plate 3 inside the reinforcing cage. At this time, the concrete hits the pressure plate 3 and causes the pressure plate 3 to move downward. Due to the limitation by the pressure plate 3 and the tilting rods 8, during the downward movement of the pressure plate 3, the anti-floating rods 7 are driven to rotate into the outer space of the reinforcing cage. As a result, the anti-floating rods 7 can penetrate into the surrounding bottom layer 11 or rock layers of the borehole and achieve an anchoring effect. At the same time, a downward pressure is applied to the reinforcing cage in order to prevent the reinforcing cage from floating.As shown in FIGS. 1, 2, 3, and 5, in some embodiments, the anchor device further includes cone tips, the cone tips being disposed at other ends of the anti-floating rods 7, and the cone tips facilitating penetration of the anti-floating rods 7 into the ground. The cone tips allow the anti-floating rods 7 to penetrate more easily into the ground, thereby improving their anchoring effect.In this embodiment, the anti-floating rods 7 are arc-shaped so that the angle between the cone tips and the ground when penetrating into the ground is about 90°, which allows the cone tips to more easily penetrate into the ground.As illustrated in FIGS. 1 and 4, in some embodiments, the anchoring device further includes a multiaxial connecting socket 5, a first socket for connection to the support rod 4 is disposed on the multiaxial connecting socket 5, and second sockets for connection to the bottom rods 6 are disposed on the multiaxial connecting socket 5. The bottom bars 6 are welded to the longitudinal steels 1 or reinforcing bars 2 to form a connection between the support bar 4 and the reinforcing cage. During the welding process it must be ensured that the support rod 4 is parallel to the longitudinal steels 1 and is preferably arranged in the central position of the reinforcing cage.In this embodiment, depending on various specifications of the reinforcing cage, various floor rods 6 and support rods 4 may be selected to improve the adaptability of the reinforcing cage floating prevention anchor device and thus to enhance the feasibility thereof of the reinforcing cage floating prevention anchor device. The connection type between the support rod 4 and the first bushing is either a screw connection or a welded connection, and preferably a welded connection. The connection type between the bottom rods 6 and the second bushes is either a screw connection or a welded connection, and preferably a welded connection.As illustrated in FIGS. 1 and 4, a plurality of second bushings are provided in some embodiments, and the plurality of second bushings are circumferentially spaced at a lower end of the first bushing. A plurality of second bushes may connect a plurality of floor rods 6. First, a plurality of bottom rods 6 contribute to the improvement in the stability of the support rod 4, and also a plurality of anti-floating rods 7 may be mounted on the plurality of bottom rods 6 respectively to ensure the floating prevention effect.As illustrated in FIG. 5, in some embodiments, the anchor device further includes: rotation axis parts 9, the rotation axis parts 9 being disposed on a lower side of the pressure plate 3; and rotation axis holes 10, the rotation axis holes 10 being disposed on the ends of the anti-floating rods 7. Each rotating axis part 9 includes end plates at both ends and a central rotating axis. The end plates at both ends are connected to the rotation axis by welding. By welding one end plate on the rotation axis, then passing the rotation axis through the rotation axis hole 10, welding the other end plate thereon, and finally welding the end plates on the lower surface of the pressure plate 3, a rotatable connection can be formed between the anti-floating rods 7 and the pressure plate 3.In this embodiment, the manner of rotatable connection between the slant bars 8 and the anti-floating bars 7 is identical to the manner of rotatable connection between the anti-floating bars 7 and the pressure plate 3, and the manner of rotatable connection between the slant bars 8 and the bottom bars 6 is identical to the manner of rotatable connection between the anti-floating bars 7 and the pressure plate 3. The other ends of the slant rods 8 are rotatably connected to the central portions of the anti-floating rods 7.As illustrated in FIGS. 1, 2, and 3, in some embodiments, the anchor device further includes a restricting part, the restricting part being disposed at an upper end of the support rod 4. The restricting part prevents the pressing plate 3 from being repelled from the upper surface of the support rod 4 and from being removed from the support rod 4.The above descriptions are directed to only some or preferred embodiments of the present invention. Neither the texts nor the drawings can therefore limit the scope of protection of the present invention.
