[0001] The utility model relates to the technical field of pipe pile production auxiliary components, in particular to a concrete pile connector. Background Art

[0002] Pipe piles are essential building materials for modern building infrastructure. Prestressed concrete pipe piles are the most common. During the production process, this type of pipe pile will first make an internal steel cage skeleton, install end plates at the ends, and then pour concrete. In order to improve production efficiency during the production process, a method of producing multiple pipe piles on the same production line is now adopted. Specifically, after making more than two steel cages, the end plates at the adjacent ends of two adjacent steel cages are connected by a concrete pile connector, and then the steel cages of the two or more connected pipe piles are loaded into the mold for concrete pouring. The existing concrete pile connector is an integral non-detachable structure with a seal inside, but the seal has poor durability and a short service life.

[0036] A sealing rubber ring 2, wherein the sealing rubber ring 2 is installed on the rubber ring installation part 11. When the connecting plate body 10 of a pair of connecting plates 1 is respectively connected to two oppositely arranged precast concrete pile end plates, the two rubber ring installation parts 11 are arranged oppositely, and the sealing rubber rings 2 on the two rubber ring installation parts 11 are pressed against each other so that the ends of the two rubber ring installation parts 11 are sealed;

[0037] The clamp 3 is used to fix the pair of connecting plates 1 connected to the precast concrete pile end plates.

[0038] The precast concrete pile connector disclosed in the utility model is provided with a pair of connecting plates arranged opposite to each other, and the connecting plates are provided with rubber ring mounting parts, so that after the connecting plates are connected to the ends of the precast concrete piles, the sealing rubber rings arranged on the rubber ring mounting parts can be squeezed against each other to form an end seal, and the pile connector has the advantages of simple structure, easy use, etc.

[0039] Specifically, in this embodiment, Figure 4 , Figure 5 and Figure 6 As shown, the connecting plate body 10 is provided with a plurality of connecting holes 12 corresponding to the threaded holes on the precast concrete pile end plate, and the connecting plate body 10 is connected to the precast concrete pile end plate by bolts 40. By providing the connecting holes on the connecting plate body, the connection between the connecting plate and the end of the precast concrete pile can be quickly and conveniently achieved by bolts. The connecting plate body 10 and the rubber ring mounting portion 11 of the connecting plate 1 in the present application can be integrally processed or separately processed, and an integral structure is formed by welding or the like after processing.

[0040] Furthermore, the outer diameter of the rubber ring installation part 11 is smaller than the outer diameter of the connecting plate body 10. After the two connecting plate bodies 10 are connected to the precast concrete pile end plate 4, an operating space 13 is formed between the two connecting plate bodies 10, that is, the connecting plate is a flange-like structure, one end of the connecting plate body is used to contact the precast concrete pile end plate and be connected by bolts, and the other end is provided with a rubber ring installation part for installing a sealing rubber ring to achieve sealing between the two connecting plates. At the same time, the operating space is formed between the two connecting plate bodies, which can facilitate operators to drive bolts through corresponding tools to achieve connection or separation of the connecting plate body and the precast concrete pile end plate.

[0041] In this embodiment, if Figure 7As shown, the sealing rubber ring 2 includes a sealing rubber ring fixing part 20 and a sealing rubber ring extrusion part 21; the sealing rubber ring fixing part 20 is sleeved on the outer diameter of the rubber ring mounting part 11, and the sealing rubber ring extrusion part 21 is arranged at the end of the rubber ring mounting part 11, that is, the sealing rubber ring as a whole is a stepped sleeve structure, and the thickness of one end thereof is relatively small to form a sealing rubber ring fixing part, and the thickness of the other end is relatively large to form a sealing rubber ring extrusion part. When the sealing rubber ring fixing part is sleeved on the rubber ring mounting part, the sealing rubber ring extrusion part is tightly fitted with the end of the rubber ring mounting part. Preferably, the inner diameter of the sealing rubber ring extrusion part is less than or equal to the inner diameter of the rubber ring mounting part. The sealing rubber ring is provided with a sleeve structure of the sealing rubber ring fixing part, which can facilitate the quick and firm connection between it and the rubber ring mounting part. The inner diameter of the sealing rubber ring extrusion part is less than or equal to the inner diameter of the rubber ring mounting part, which can effectively ensure the sealing between the ends of the two connecting plates.

[0042] Furthermore, an anti-falling structure is provided between the outer diameter of the sealing rubber ring fixing portion 20 and the rubber ring mounting portion 11. Figure 4 and Figure 7 As shown. The anti-falling structure is an anti-falling protrusion and an anti-falling groove arranged between the sealing rubber ring fixing part 20 and the rubber ring mounting part 11. In this embodiment, an anti-falling groove 14 is provided on the rubber ring mounting part 11, and an anti-falling protrusion 22 is provided in the inner ring of the sealing rubber ring fixing part 20. When the sealing rubber ring fixing part 20 is sleeved on the rubber ring mounting part, the anti-falling protrusion is stuck in the anti-falling groove. The anti-falling structure is provided, which can make the connection between the sealing rubber ring and the connecting plate more firmly, and avoid the problem of the sealing rubber ring falling off during use and affecting the production of precast concrete piles. At the same time, when the sealing rubber ring is damaged, it can be easily replaced.

[0043] Preferably, the sealing rubber ring is made of silicone, which has strong tensile strength and tear resistance, good elasticity, excellent heat resistance and corrosion resistance, and prolongs the service life.

[0044] In this embodiment, if Figure 8 , Fig. 9 and Fig.10As shown, the clamp 3 includes two clamp petals 30 that can be buckled with each other, and the two clamp petals 30 are buckled to form a clamp cavity 31; a clamp structure is provided between the clamp petals 30 and the connecting plate body 11; the two clamp petals 30 can be buckled on the connecting plate body 11, so that the connecting plate 1 is placed in the clamp cavity 31 and the two connecting plates 1 are fixedly connected through the clamp structure. Specifically, the outer size of the clamp petals is adapted to the cavity size of the precast concrete pile mold, and the clamp petals can be placed in the cavity of the precast concrete pile mold. The connecting plate body 10 is provided with a radially outward clamping protrusion 15, and the clamp cavity 31 is provided with a clamping groove 32. When the clamp petals 30 are buckled on the connecting plate 1, the clamping protrusion 15 is clamped into the clamping groove 32, that is, when the two clamp petals are buckled with each other, the two connecting plates are clamped together by the two clamp petals to achieve a quick connection between the two connecting plates.

[0045] Furthermore, a separation hole 33 is provided between the two clamp petals 30. The separation hole can facilitate the rapid separation of the two clamp petals by inserting a rod-shaped tool such as a crowbar into the separation hole after the precast concrete pile is manufactured.

[0047] like Fig.11 As shown, the steel cages of the two precast concrete piles are respectively placed in the precast concrete pile mold, a certain distance is left between the end plates at the opposite ends of the two steel cages, and a clamp petal is placed between the end plates at the opposite ends of the two steel cages in the mold, and two connecting plates are respectively placed in the clamp petals, and the connecting plates are connected to the precast concrete pile end plates 40 on the corresponding sides by bolts. At this time, the two sealing rubber rings are squeezed against each other to make the end of the connecting plate sealed, and then the other clamp petal is buckled. Since the clamp petal and the connecting plate are provided with a snap-fit ​​structure, the two connecting plates are connected by the clamp. The other end plate of one of the steel cages is connected to the fixed plate on the mold, and the other end plate of the other steel cage is connected to the tensioning plate. After pouring concrete into the mold, the upper mold of the precast concrete pile is buckled, and one end of the mold can tension the tensioning plate through a tensioning device, thereby tensioning the main bars of the steel cage on the corresponding side. At the same time, the two steel cages are connected by a pile connector, thereby tensioning the main bars of the two steel cages. At the same time, other subsequent processes in the precast concrete pile production process can be carried out.
