The elastic telescopic components 51 all comprise a gasket 510, a buffer spring 511 and two sliding bars 512, each sliding bar 512 is slidably arranged on the inner wall of the second sleeve 2, the gasket 510 is fixedly arranged between the two sliding bars 512, the buffer spring 511 is sleeved at the bottom of the gasket 510, after the spherical plug connector 3 is installed, the outer wall of the spherical plug connector is just attached to the inner wall of the circular sleeve 50 at the top of the gasket 510, the gasket 510 is slidably connected with the inner wall of the second sleeve 2 through the two sliding bars 512, the top of the steel bar on the second sleeve 2 and the outer wall of the gasket 510 are respectively sleeved with the two ends of the buffer spring 511, so that the gasket 510 and the steel bar on the second sleeve 2 realize stress transmission through the buffer spring 511, meanwhile, the caulking groove 500 is designed in the circular sleeve 50, the gasket 510 is attached to the spherical plug connector 3 more tightly, and smooth stress transmission is formed between the steel bar in the first sleeve 1 and the steel bar in the second sleeve 2, therefore, the detection method and the detection index under the existing standard are met, and the buffer spring 511 and the gasket 510 with the sliding design can play a certain buffer role when the prefabricated member is vibrated, so that the anti-seismic performance of the tubular pile is improved.
The working principle of the invention is as follows: when carrying out the butt joint of prefab, need use two reinforcing bars, then all upset the one end of two reinforcing bars and become the upset joint in first sleeve pipe 1 and second sleeve pipe 2's inside, because the fixed connecting rod 30 that is equipped with in top of spherical bayonet joint 3, the fixed threaded rod 300 that is equipped with in top of connecting rod 30, because threaded rod 300 and the inner wall threaded connection of first sleeve pipe 1 again, therefore with the inside of spherical bayonet joint 3 screw in first sleeve pipe 1.
After spherical bayonet joint 3 screw in first sleeve pipe 1's inside, cup joint second sleeve pipe 2 to first sleeve pipe 1 bottom, at this moment, inserted bar 41 inserts in the jack, two expanding spring 421 receive shrink behind the impetus of inserted bar 41 outer wall, because every toper buckle 420 all cup joints with two guide arms 422, every expanding spring 421 all cup joints with a guide arm 422, therefore make toper buckle 420 shrink in the jack inside, and when toper draw-in groove on the inserted bar 41 slides to when 420 parallel and level with toper buckle, the impetus of inserted bar 41 outer wall to toper buckle 420 disappears, two expanding spring 421 reset, thereby drive toper buckle 420 and stretch out to the inside chucking that carries out of toper draw-in groove, be about to the outer lane of first sleeve pipe 1 and the outer lane locking of second sleeve pipe 2.
When inserting the inserted bar 41 in first sleeve 1 bottom to the jack at second sleeve 2 top, spacing and spacing groove grafting cooperation to guarantee that spacing guide pillar 40 can insert the second pipe, and then make the accurate butt joint of first sleeve 1 and second sleeve 2, and effectively avoid spherical bayonet joint 3 to produce the phenomenon of turning a little when inserting to locking mechanism 6, and then guarantee the straightness of prefab, and then be favorable to promoting the preparation quality of the prefab after two docks.
Before the first sleeve 1 and the second sleeve 2 are plugged, firstly, a locking ring 60 for locking the spherical plug connector 3 is installed inside the second sleeve 2, the locking ring 60 corresponds to the four installation blocks along the gap, then the locking ring 60 is pressed into the tops of the four arc-shaped overlapping blocks 21, the four arc-shaped overlapping blocks 21 play a supporting role, and then the locking ring 60 is manually rotated.
When the locking ring 60 is manually rotated, the spherical buckle 620 slides along the arc avoiding groove at the bottom of the locking ring 60, the arc avoiding groove plays a role in reducing the sliding friction force between the spherical buckle 620 and the bottom of the locking ring 60, thereby facilitating the rapid and accurate rotation of the locking ring 60, during the rotation of the locking ring 60, the collision spring 623 automatically contracts due to the collision force of the locking ring 60, thereby driving the spherical buckle 620 to contract, and when the spherical buckle groove rotates to be right above the spherical buckle 620, the collision spring 623 resets, because the inner rod 621 is fixedly connected with the cylindrical projection 624, the inner rod 621 is inserted into the sleeve rod 622, and because the bottom of the cylindrical projection 624 and the bottom of the through hole respectively collide with the two ends of the collision spring 623, thereby driving the spherical buckle 620 to enter the inside of the spherical buckle groove, thereby locking the bottom of the locking ring 60, at this time, because the top of the locking ring 60 is attached to the bottom of each mounting block, therefore, the bottoms of the four mounting blocks lock the top of the locking ring 60, so that the top and the bottom of the locking ring 60 are limited, and the limiting blocks are completely fixed.
When the locking ring 60 is fixed, the locking ring 60 is sleeved on the spherical plug 3, the spherical plug 3 is inserted into the center of the locking ring 60 through the limiting piece 20, at this time, after the two return springs 601 are stressed by the spherical plug 3, because one end of the conical cutting sleeve 61 close to the locking ring 60 is fixedly connected with two ends of the rectangular through groove respectively of the return springs 601, the two plug columns 600 play a guiding role, so that the conical cutting sleeve 61 is contracted towards one end close to the rectangular through groove, and when the spherical plug 3 completely enters between the two conical cutting sleeves 61, the return springs 601 are reset, the arc-shaped clamping groove 610 clamps the spherical plug 3, the spherical plug 3 is prevented from being easily separated from the locking ring 60, the bevel angle structure facilitates the spherical plug 3 to enter between the two conical cutting sleeves 61 when contacting the top of the conical cutting sleeve 61, thereby facilitating the improvement of the locking efficiency, and two toper cutting ferrule 61 of elastic sliding design realize that spherical bayonet joint 3 can easily insert and can prevent after inserting and deviate from, can reduce the wearing and tearing that the plug brought to inserting firmly between two toper cutting ferrule 61 among the prior art again, be favorable to prolonging the life of toper cutting ferrule 61, realize reuse, be favorable to reducing the butt joint cost of prefab.
After the spherical plug 3 is installed, the outer wall of the spherical plug is just attached to the inner wall of the circular sleeve 50 at the top of the gasket 510, the gasket 510 is slidably connected to the inner wall of the second sleeve 2 through two sliding bars 512, the top of the steel bar on the second sleeve 2 and the outer wall of the gasket 510 are respectively sleeved with two ends of the buffer spring 511, so that the gasket 510 and the steel bar on the second sleeve 2 realize stress transmission through the buffer spring 511, meanwhile, the caulking groove 500 is designed in the circular sleeve 50, so that the gasket 510 is more closely attached to the spherical plug 3, and further, unobstructed stress transmission is formed between the steel bar in the first sleeve 1 and the steel bar in the second sleeve 2, thereby satisfying the detection method and detection index under the existing standard, and the buffer spring 511 and the gasket 510 designed in a sliding manner can achieve a certain buffer effect when the prefabricated member is vibrated, thereby being beneficial to improving the anti-seismic performance of the tubular pile.
