Description

Technical Field

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

[0002] A foundation pile consists of the foundation piles and the pile cap connected to the top of the piles. If the entire pile is buried in the soil and the bottom of the pile cap is in contact with the soil, it is called a low pile cap foundation. If the upper part of the pile is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high pile cap foundation. During construction, fastening devices are used to secure the foundation piles to ensure their stability.

[0003] The published patent document with announcement number CN209722967U discloses a foundation pile fastening device for building construction. This published patent document has a simple structure and is easy to use, which can facilitate the fixing of the foundation pile body, thereby reducing the inconvenience caused by construction. However, the published patent document can only fasten and fix a single foundation pile, and there is no reinforcement connection between the foundation piles. The pile cap alone can only reinforce the top of the foundation pile. Since the foundation pile as a whole has a long length, when a single foundation pile settles or tends to shift, the other foundation piles cannot provide connection and reinforcement, and cannot guarantee the tightness between all foundation piles in the entire construction area.

Several connecting lugs are fixedly connected to the top of the fastening plate. Connecting lugs are symmetrically fixedly connected to the two sides of the square sleeve. Mounting bolts are threaded through and connected to the connecting lugs. Connecting lugs one, two, and three are all compatible with the mounting bolts.

[0008] By adopting the above technical solution, the anchor rods connected to the thread on the fastening plate are screwed into the ground to fasten a single foundation pile. The installation bolts are then screwed into connecting lug one, connecting lug three, and connecting lug two in sequence to connect the fastening plate and the connecting reinforcement components, thus achieving double fastening of the foundation pile.

[0009] Optionally, the foundation pile has several threaded grooves that match the mounting bolts, and one end of the mounting bolt passes through the rectangular sleeve and is located inside the threaded groove.

[0010] By adopting the above technical solution, the installation of the rectangular sleeve and the foundation pile can be completed by screwing the mounting bolt into the corresponding thread groove.

[0011] Optionally, the anchor bolt is a self-drilling anchor bolt.

[0012] By adopting the above technical solution, the anchor rod can be rotated into the ground without drilling.

[0013] Optionally, there is a gap between every two reinforcing rods, and the length of the gap between two reinforcing rods is greater than the sum of the lengths of one screw and one round shaft.

[0014] By adopting the above technical solution, it is ensured that both screws can be screwed into the corresponding threaded holes.

[0015] Optionally, the outer wall of the circular shaft is provided with anti-slip texture.

[0016] By adopting the above technical solution, it is convenient to rotate the screw.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses rectangular sleeves, square sleeves, through holes, reinforcing rods, grooves, connecting ears, springs, round shafts, threaded holes and screws to facilitate the installation of the connecting and reinforcing components between two foundation piles, so that there is a connection and reinforcement between each foundation pile. When a single foundation pile settles or shifts, the remaining foundation piles can reinforce the single foundation pile, increasing the tightness between all foundation piles in the entire construction area.

[0019] 2. The technical solution of this application can fasten a single foundation pile by screwing the anchor rod connected to the fastening plate into the ground. Furthermore, by screwing the installation bolts into the connecting lug 1, connecting lug 3, and connecting lug 2 in sequence, the fastening plate and the connecting reinforcement component can be connected, thereby achieving double fastening of the foundation pile.

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

[0027] Please see Figure 1-4This utility model provides a foundation pile fastening device for building construction, including several foundation piles 1 and several sets of connecting and reinforcing components 3. Each set of connecting and reinforcing components 3 is set between two adjacent foundation piles 1. A rectangular sleeve 2 is fitted on the foundation pile 1. A square sleeve 7 is welded to the four sides of the outer wall of the rectangular sleeve 2. Two through holes 8 are opened on the square sleeve 7. Each set of connecting and reinforcing components 3 includes a round shaft 32 and two reinforcing rods 31. The reinforcing rods 31 are adapted to the square sleeves 7. Grooves 33 are symmetrically opened on both sides of one end of the reinforcing rod 31, and a threaded hole 36 is opened at the other end of the reinforcing rod 31. A connecting lug 34 matching the through hole 8 is slidably connected inside the groove 33. A spring 35 is fixedly connected to one end of the connecting lug 34 inside the groove 33. One end of the spring 35 is fixedly connected to the inner wall of the groove 33. Both ends of the round shaft 32 are fixedly connected to screws 37 matching the threaded hole 36.

[0028] In this technical solution, by applying a force to the connecting lug 34 into the groove 33, the connecting lug 34 compresses the spring 35 and fully enters the groove 33. Then, one end of the reinforcing rod 31 is inserted into the square sleeve 7. The spring 35 drives the connecting lug 34 to reset and pass through the through hole 8, completing the installation between the reinforcing rod 31 and the rectangular sleeve 2. Then, a screw 37 is fully screwed into the threaded hole 36. Similarly, another reinforcing rod 31 is installed between the rectangular sleeve 2 of another foundation pile 1. Finally, the round shaft 32 is rotated to screw another screw 37 into the threaded hole 36, thus installing the connecting and reinforcing assembly 3 between the two foundation piles 1, so that there is a connection and reinforcement between each foundation pile 1. When a single foundation pile 1 settles or shifts, the remaining foundation piles 1 can connect and reinforce the single foundation pile 1, increasing the tightness between all foundation piles 1 in the entire construction area.

[0029] In some technical solutions, such as Figure 1-3 As shown, a fastening plate 4 is fitted and welded onto the foundation pile 1. Anchor rods 5 are threaded through and connected to the four corners of the fastening plate 4. Several connecting ears 9 are fixedly connected to the top of the fastening plate 4. Connecting ears 10 are symmetrically fixedly connected to both sides of the square sleeve 7. Mounting bolts 11 are threaded through and connected to the connecting ears 9. Connecting ears 9, connecting ears 10 and connecting ears 34 are all compatible with mounting bolts 11.

[0030] In use, the anchor rod 5 threaded on the fastening plate 4 can be screwed into the ground to fasten a single foundation pile 1. The fastening plate 4 can be connected to the connecting reinforcement component 3 by screwing the mounting bolt 11 into the connecting ear 9, connecting ear 34 and connecting ear 2 10 in sequence, thereby doubly fastening the foundation pile 1.

[0031] In some technical solutions, such as Figure 2-3As shown, the foundation pile 1 has several threaded grooves 6 that match the mounting bolts 11. One end of the mounting bolt 11 passes through the rectangular sleeve 2 and is located inside the threaded grooves 6.

[0032] In use, the installation between the rectangular sleeve 2 and the foundation pile 1 can be completed by screwing the mounting bolt 11 into the corresponding threaded groove 6.

[0033] In some technical solutions, such as Figure 1-2 As shown, anchor bolt 5 is a self-drilling anchor bolt.

[0034] In use, the self-drilling anchor rod 5 can be rotated into the ground without drilling.

[0035] In some technical solutions, such as Figure 4 As shown, there is a gap between every two reinforcing rods 31, and the length of the gap between two reinforcing rods 31 is greater than the sum of the lengths of a screw 37 and a round shaft 32.

[0036] When using, ensure that both screws 37 can be screwed into the corresponding threaded holes 36.

[0037] In some technical solutions, such as Figure 4 As shown, the outer wall of the circular shaft 32 is provided with anti-slip texture.

[0038] When in use, the anti-slip texture on the outer wall of the round shaft 32 facilitates the rotation of the screw 37.

[0039] Working principle: During installation, the anchor rod 5 threaded onto the fastening plate 4 is screwed into the ground to secure a single foundation pile 1. A force is applied to the connecting lug 34 into the groove 33, causing the connecting lug 34 to compress the spring 35 and fully enter the groove 33. Then, one end of the reinforcing rod 31 is inserted into the square sleeve 7. The spring 35 drives the connecting lug 34 to reset and pass through the through hole 8, completing the installation between the reinforcing rod 31 and the rectangular sleeve 2. Then, a screw 37 is fully screwed into the threaded hole 36. Similarly, the other reinforcing rod 31 is connected to the other... The rectangular sleeves 2 of the foundation pile 1 are installed between each other. Finally, the round shaft 32 is rotated so that another screw 37 is screwed into the threaded hole 36, and the connecting reinforcement component 3 can be installed between the two foundation piles 1, so that there is a connection and reinforcement between each foundation pile 1. When a single foundation pile 1 settles or shifts, the other foundation piles 1 can connect and reinforce the single foundation pile 1. Finally, the mounting bolts 11 are screwed into the connecting ear 1 9, connecting ear 3 34 and connecting ear 2 10 in sequence, so that the fastening plate 4 and the connecting reinforcement component 3 are connected, thereby doubly fastening the foundation pile 1.
