Description

Technical Field

[0001] This utility model relates to the field of pile foundation fixing technology, specifically a pile foundation safety fixing device for building engineering. Background Technology

[0002] As is well known, a pile foundation is a deep foundation in which the tops of several piles are connected into a whole by a pile cap to jointly bear dynamic and static loads. A pile is a vertical or inclined foundation component set in the soil. Its function is to penetrate soft, highly compressible soil layers or water and transfer the load borne by the pile to a harder, denser or less compressible bearing layer. We usually refer to the piles in a pile foundation as foundation piles.

[0003] Chinese Utility Model Publication No. CN218060309U discloses a safety fixing device for pile foundations in building engineering, including a fixing ring, with mounting seats fixedly installed on both the left and right side walls of the fixing ring, a first support plate rotatably installed in the mounting seat, a mounting groove opened at one end of the first support plate, a second support plate slidably installed in the mounting groove, and a positioning component rotatably installed at the bottom end of the second support plate; a locking component, of which there are two sets, each locking component including a threaded rod rotatably installed at the bottom of the mounting groove, with the two second support plates respectively threadedly sleeved on the two threaded rods; and a limiting component, of which there are two sets, the two sets of limiting components being used to limit the rotation of the two second support plates respectively.

[0004] Although the device adjusts the total length of the first and second support plates, the threaded rod is exposed. When it rains, rainwater flows down the threaded rod and enters the gap where the threads of the second support plate connect. Over time, this will corrode the threaded rod and other components. Since the device does not have a mechanism to block rainwater, its practicality is not very good and there is room for improvement. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a pile foundation safety fixing device for building engineering, which has the feature of improving practicality.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pile foundation safety fixing device for building engineering, comprising several fixing rings, a threaded tube rotatably connected to one side of each fixing ring, a screw threadedly connected to the lower part of the threaded tube, a support rod provided at the lower part of the screw, a support plate rotatably connected to the lower part of the support rod, a blocking tube provided outside the threaded tube for blocking the lower opening of the threaded tube, a sliding tube rotatably connected outside the screw and slidingly disposed within the blocking tube, thereby blocking the opening of the screw and the threaded tube through the sliding of the sliding tube and the blocking tube.

[0009] Furthermore, a sealing component is provided on the upper part of the sliding tube, and the outer end face of the sealing component is in contact with the inner wall of the shielding tube to improve the sealing performance between the shielding tube and the sliding tube.

[0010] Furthermore, the sealing assembly includes a connecting ring fixedly disposed with the sliding tube, and a sealing gasket that provides a sealing effect is disposed on the outside of the connecting ring.

[0011] Furthermore, the lower part of the screw is provided with several limiting rings, and one end face of each of the limiting rings is in contact with the sliding tube.

[0012] Furthermore, the diameter of the limiting ring is smaller than the inner diameter of the sliding tube, so that when the screw and the sliding tube rotate relative to each other, the outer wall of the limiting ring located inside the sliding tube will not rub against the inner wall of the sliding tube.

[0013] Preferably, each of the fixing rings has a threaded hole on both sides and is threaded with a bolt.

[0014] Preferably, the support plate has a mounting hole in the middle for installing a grounding anchor rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a safety fixing device for pile foundations in building engineering, which has the following beneficial effects:

[0017] The safety fixing device for pile foundations used in this construction project can cover the opening of the threaded pipe and the screw rod by sliding the sliding tube on the shielding tube during rain. When the rainwater comes into contact with the sliding tube or the shielding tube, it flows along the pipe wall and falls to the ground, so the rainwater will not corrode the connection between the screw rod and the threaded pipe, thus improving its practicality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7This utility model discloses a safety fixing device for pile foundations in building engineering, comprising several fixing rings 1. A threaded tube 2 is rotatably connected to one side of each fixing ring 1. A screw 3 is threadedly connected to the lower part of the threaded tube 2. By controlling the length of the screw 3 extending out of the threaded tube 2 after rotation within the threaded tube 2, the downward movement distance of the screw 3 can be adjusted. A support rod 4 is provided at the lower part of the screw 3. By adjusting the length of the screw 3 extending out of the threaded tube 2, the downward movement distance of the support rod 4 can be adjusted, thereby adjusting the overall height of the support rod 4, the screw 3, and the threaded tube 2. A support plate 5 is rotatably connected to the lower part of the support rod 4. When the support rod 4 moves downward, it drives the support plate 5 to support the ground, thereby fixing the device. A shielding pipe 6 is provided on the outside of the threaded pipe 2 to shield the lower opening of the threaded pipe 2. A sliding pipe 7 is rotatably connected to the outside of the screw 3 and is slidably arranged inside the shielding pipe 6. By sliding the sliding pipe 7 and the shielding pipe 6, the openings of the screw 3 and the threaded pipe 2 can be shielded to prevent rainwater from adhering to the openings of the screw 3 and the threaded pipe 2 during rain, thereby preventing corrosion of both.

[0028] A sealing component is provided on the upper part of the sliding tube 7. The outer end face of the sealing component is in contact with the inner wall of the shielding tube 6 to improve the sealing between the shielding tube 6 and the sliding tube 7, and to prevent rainwater from entering the interior from the connection between the two and corroding the screw 3 and the threaded tube 2.

[0029] The sealing assembly includes a connecting ring fixedly disposed with the sliding tube 7. A sealing gasket 8 is disposed on the outside of the connecting ring to provide a sealing effect. One end of the sealing gasket 8 is attached to the inner wall of the shielding tube 6 to perform a sealing function.

[0030] The lower part of the screw 3 is provided with several limiting rings 9. One end face of each limiting ring 9 is in contact with the sliding tube 7. The limiting rings 9 are used to ensure that the sliding tube 7 rotates between the two and does not move along the axis of the screw 3.

[0031] The diameter of the limiting ring 9 is smaller than the inner diameter of the sliding tube 7, so that when the screw 3 and the sliding tube 7 rotate relative to each other, the outer wall of the limiting ring 9 located inside the sliding tube 7 will not rub against the inner wall of the sliding tube 7, thus not affecting the relative rotation of the two.

[0032] Several fixing rings 1 have threaded holes on both sides, and each is threaded with a bolt 10. By screwing the bolts 10 into the threaded holes of the fixing rings 1, the fixing rings 1 can be fixed to the outer wall of the pile foundation.

[0033] The support plate 5 has a mounting hole 11 in the middle for installing a grounding anchor rod. By passing the grounding anchor rod through the mounting hole 11 and extending it into the ground, the support plate 5 can be fixed on the ground, thereby fixing the support rod 4, screw 3, threaded pipe 2 and fixing ring 1.

[0034] In summary, the pile foundation safety fixing device used in this construction project is operated by having workers clamp the fixing rings 1 on both sides of the pile foundation, screw the bolts 10 into the threaded holes on both sides of the fixing rings 1 to fix the two fixing rings 1 to the pile foundation, then grasp one side of the support rod 4 and rotate it, causing the screw rod 3 to rotate and move downwards within the threaded tube 2, which in turn causes the support plate 5 at the bottom of the support rod 4 to move downwards. At the same time, the screw rod 3 causes the sliding tube 7 to slide within the shielding tube 6, and the sealing gasket 8 adheres to the inner wall of the shielding tube 6. Slide and seal. After the lower part of the support plate 5 is supported on the ground, pass the grounding anchor rod through the mounting hole 11 of the support plate 5 and extend it into the ground to fix the support plate 5. Then fix the other side of the support plate 5 to the ground in the same way. When it rains, the rainwater flows to the shielding pipe 6 and flows down along the outer wall of the shielding pipe 6. When it flows to the outer wall of the sliding pipe 7, it flows under its own gravity to the limiting ring 9 at the lower part of the sliding pipe 7 and flows to the support rod 4 and flows down.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
