The working principle and working method for assembling the building connection node provided by the embodiment of the invention are as follows:
first, one end of each of the positioning rods 251 is inserted into the bar-shaped hole of the prefabricated member 110 until the clamping block 260 enters the installation groove, and then the prefabricated member 110 is inserted into the connection plate frame 240, and the other end of the positioning rod 251 is inserted into one of the grouting sleeves 120 at the corresponding position. The first connecting pipe 121 is inserted into the first fixed pipe 123, and the second connecting pipe 122 is sleeved on the second fixed pipe 124 through threaded connection, wherein when the second connecting pipe 122 is sleeved on the second fixed pipe 124, the end of the second connecting pipe 122 pushes the sliding frame 140 to move along the second fixed pipe 124 to a side close to the grouting sleeve 120, so that the rack 141 drives the gear 230 to rotate, the gear 230 drives the ball valve 270 to rotate, and the channel of the second fixed pipe 124 is opened.
During the process of inserting the second connecting pipe 122 into the second fixed pipe 124, when the end surface of the second fixed pipe 124 moves to contact with the stopper 220 inside the second connecting pipe 122, the stopper 220 pushes the blocking plate 210 to move to a side close to the second fixed pipe 124 by hydraulic oil, so that the middle channel on the second piston plate 190 is opened.
Then, the nozzle of the grouting device is inserted into the first connecting pipe 121 and contacted with the two second baffles 160, so that the first piston plate 150 is pushed to move close to one side of the grouting sleeve 120, the grouting nozzle pushes the two second baffles 160 open to start grouting until the first piston plate 150 reaches the limit position, and the slurry pushes the two second baffles 160 on the first connecting pipe 121 open to enter the grouting sleeve 120 until the interior of the grouting sleeve 120 is filled with the slurry.
When the slurry enters the second fixed pipe 124, since the ball valve 270 is in the blocking state at this time, the slurry can enter between the second piston plate 190 and the first piston plate 150 through the through hole of the second piston plate 190, push the first piston plate 150 of the second connecting pipe 122 to the second position, and when the sensing post 180 of the first baffle 170 contacts the third baffle 130, the sensing post 180 pulls the first baffle 170 to gradually close the ventilation hole. After detecting that the air holes 151 are closed, the induction controller controls the grouting equipment to be closed, and the grouting sleeve 120 is stopped from being filled with slurry. And then the first connecting pipe 121 and the second connecting pipe 122 on the grouting sleeve 120 are removed before grouting the next grouting sleeve 120, and the installation position is adjusted in the next grouting operation, namely the original first connecting pipe 121 is arranged outside the second fixed pipe 124 through a threaded connecting sleeve to serve as a new second connecting pipe 122, the original second connecting pipe 122 is sleeved outside the first fixed pipe 123 to serve as a new first connecting pipe 121, so that the slurry in the second connecting pipe 122 in the last working state can be injected into the grouting sleeve 120, the residual slurry in the original second connecting pipe 122 is basically emptied, the waste of the slurry is avoided, and the grouting sleeve 120 is filled with the slurry.
When the first connection pipe 121 and the second connection pipe 122 are used, they may be washed by an external washing apparatus.
When the second connection pipe 122 is disassembled, the ball valve 270 is closed, and a cap is screwed on the end of the first fixing pipe 123 after the first connection pipe 121 is disassembled, preventing leakage of slurry.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
