As shown in fig. 5, a base 8 is arranged below the bead outlet groove 3, an arc-shaped receiving space is arranged above the base 8, the arc-shaped receiving space is used for receiving the protrusion 9, and horizontal supporting surfaces are respectively arranged above the base 8 at two sides of the arc-shaped receiving space and are used for contacting with the blocking portion 401 of the blocking piece 4, so as to support the blocking piece 4 at the blocking position.

As shown in fig. 5, the bottom of the blocking portion 401 of the blocking member 4 is provided with a relief groove 10 for facing the accommodating space of the base 8, the relief groove 10 is used for preventing the blocking member 4 from being jacked up due to the large diameter of the protrusion 9, and the relief groove 10 may be an arc-shaped groove or an arc-shaped chamfer.

As shown in fig. 8, when the receding groove 10 on the blocking portion 401 is an arc-shaped chamfer, when the blocking piece 4 is located at the unblocking position, the receding groove 10 of the blocking portion 401 of two blocking pieces 4 may form a guide for the protrusion 9 to enter, so that the protrusion 9 can enter the rib outlet groove 3 more conveniently.

As shown in fig. 6, the plugging material 4 is located at the plugging position at this time, and in this plugging position, the plugging portion 401 of the plugging material 4 plugs the bead outlet groove 3 in the inward and outward directions. At the moment, the protrusion 9 enters the rib outlet groove 3, the protrusion 9 is supported above by the base 8, the protrusion 9 is accommodated in the arc accommodating space of the base 8, the base 8 is arranged below the blocking piece 4 above the protrusion 9, a horizontal supporting surface above the base 8 is supported at the bottom of the blocking part 401 due to the fact that the receding groove 10 is formed in the bottom of the blocking part 401, the blocking piece 4 is enabled to be stably kept at the blocking position, the blocking piece 4 is enabled to well seal the rib outlet groove 3, and concrete is prevented from flowing out of the rib outlet groove 3.

When the width of the blocking parts 401 of the two blocking pieces 4 is equal to the width of half of the rib outlet groove 3, the two blocking pieces 4 respectively block the rib outlet groove 3 by half in the inward and outward directions of the rib outlet groove 3, and the two blocking pieces 4 do not overlap in the inward and outward directions of the rib outlet groove 3, so that the rib outlet groove 3 can be blocked.

As shown in fig. 8-11, the process of the protrusion 9 entering the bead outlet 3 is described, in which the protrusion 9 enters the bead outlet 3 from above and the protrusion 9 moves down along the bead outlet 3 into the bead outlet 3.

As shown in fig. 8, before the protrusion 9 enters the bead outlet 3, the blocking member 4 is first located at the unblocking position, the blocking portion 401 of the blocking member 4 is supported by the limiting member 6, and the actuating portion 402 of the blocking member 4 blocks a path, which is required to pass by the protrusion 9 when the protrusion 9 enters the bead outlet 3, of the protrusion 9, which extends out of the main plate 1.

As shown in fig. 9, during the downward movement of the protrusion 9 along the bead 3, the protrusion 9 contacts the actuating portion 402 of the block piece 4, the protrusion 9 pushes the actuating portion 402 downward, and the block piece 4 rotates downward around the rotating shaft 5 under the pushing force of the protrusion 9, i.e. the block piece 4 starts to rotate from the unblocking position towards the blocking position.

When the protrusion 9 is about to reach the bottom of the bead 3, as shown in fig. 10, the protrusion 9 does not make contact with the actuating portion 402 of the blocking element 4, and the protrusion 9 no longer drives the blocking element 4 to rotate, but the blocking element 4 still has a tendency to rotate downwards under the influence of gravity, and the blocking element 4 continues to rotate towards the blocking position.

As shown in fig. 11, as the protrusion 9 reaches the bottom of the bead outlet groove 3, the blocking member 4 also reaches the blocking position, at this time, the blocking portion 401 of the blocking member 4 blocks the inside and outside directions of the bead outlet groove 3, the bottom end of the blocking portion 401 covers the protrusion 9, and a space is provided between the blocking portion 401 and the protrusion 9 to ensure that the protrusion 9 does not jack up the blocking member 4, so that the blocking member 4 can block the bead outlet groove 3 well.

As shown in fig. 11-14, the process of removing the bead 3 for the protrusions 9 on the prefabricated parts is described, in which the protrusions 9 are removed from below along the bead 3 up to the outside of the bead 3.

As shown in fig. 11, when the block piece 4 is in the block position, the block portion 401 of the block piece 4 is placed over the protrusion 9.

As shown in fig. 12, when the protrusion 9 contacts the bottom end of the blocking portion 401 of the blocking member 4 during the upward movement of the protrusion 9 along the bead 3, the protrusion 9 pushes the blocking member 4 upward, and the blocking member 4 rotates upward around the rotating shaft 5 under the pushing action of the protrusion 9, i.e. the blocking member 4 starts to rotate from the blocking position toward the unblocking position.

As shown in fig. 13, when the protrusion 9 pushes the blocking member 4 to rotate upward by a certain angle, the blocking member 4 has a tendency to rotate upward around the rotating shaft 5, and at the same time, since the extension length of the blocking portion 401 of the blocking member 4 is greater than the extension length of the actuating portion 402, when the blocking portion 401 obtains the rotation tendency, the rotation speed of the blocking member 4 toward the unsealing position can be increased due to the action of the blocking portion 401, so that the blocking member 4 can be rotated toward the unsealing position more quickly.

As shown in fig. 14, after the protrusion 9 moves out of the bead groove 3, the blocking member 4 rotates to the unblocking position, the blocking portion 401 of the blocking member 4 is supported on the limiting member 6, and the actuating portion 402 of the blocking member 4 continues to block on the path of the bead groove 3.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
