Specifically, the length direction of the stop lever 44 is consistent with the length direction of the guide section 411 of the rod 41, when the rod 41 is in the first state, the whole stop lever 44 is located in the mounting groove 31, after the rod 41 rotates from the first state to the second state, the rotation of the connecting rib 43 drives the stop lever 44 to rotate to be approximately vertical, because the length of the stop lever 44 is larger than the distance from the mounting ring 32 to the notch of the mounting groove 31, when the rod 41 is in the second state, one end of the stop lever 44 far away from the connecting rib 43 extends out of the opening of the mounting groove 31, when concrete pouring is carried out in the mounting groove 31, in order to enable the concrete to be evenly arranged in the mounting groove 31, the flowability of the concrete can be increased by vibration of the concrete vibrating rod, because the BDF ribbed steel net member 2 is arranged in the mounting groove 31, the BDF ribbed steel net member 2 is difficult to extend into the mounting groove 31, in this embodiment, the connecting rod 44 can be selectively arranged at one end of the connecting rib 43, and the vibration source can be installed in the mounting groove 31 in a vibration mode, or the vibration source can be filled in the vibration source 31, and the vibration source can be evenly arranged in the vibration source can be filled in the vibration groove 31, and the vibration source can be arranged in the vibration source 31, and the vibration source can be simultaneously, and the vibration source can be installed in the vibration source can be filled in the vibration groove 31.
In another embodiment of the present invention, the BDF ribbed steel mesh member 2 is provided with the second elastic piece 22, the guide section 411 of the rod 41 is provided with the clamping groove 414, and when the BDF ribbed steel mesh member 2 enters the installation groove 31, one end of the second elastic piece 22 extends into the clamping groove 414.
Specifically, the second elastic pieces 22 are provided with multiple groups and are uniformly arranged on the side wall of the BDF ribbed steel mesh member 2, and correspond to the four groups of limiting members 4, in the process that the BDF ribbed steel mesh member 2 gradually enters the mounting groove 31, the second elastic pieces 22 gradually contact the rod 41, the elastic force of the second elastic pieces 22 is smaller than that of the first elastic pieces 42, so that the rod 41 can squeeze the second elastic pieces 22, the second elastic pieces 22 gradually shrink, when the BDF ribbed steel mesh member 2 completely enters the mounting groove 31, one end of the second elastic pieces 22 moves to the clamping groove 414 to form an inverted V-shaped structure, and after the second elastic pieces 22 extend into the mounting groove 31, the second elastic pieces 22 and the BDF ribbed steel mesh member 2 are prevented from rising under the blocking of the groove wall of the clamping groove 414, the BDF ribbed steel mesh member 2 cannot rise after entering the mounting groove 31, and accordingly the phenomenon that the BDF ribbed steel mesh member 2 is reversely raised due to buoyancy when the BDF ribbed steel mesh member 2 is poured is completely inside the mounting groove 31 is avoided.
Further, the plurality of groups of the clamping grooves 414 are arranged, and the plurality of groups of the clamping grooves 414 are equidistantly arranged along the length direction of the guide section 411.
Specifically, the plurality of groups of clamping grooves 414 are provided, and the plurality of groups of clamping grooves 414 are matched with the second elastic piece 22, so that in the actual use process, when the second elastic piece 22 is separated from the clamping grooves 414, the second elastic piece 22 is clamped into other clamping grooves 414 in the lifting process of the BDF ribbed steel mesh member 2, and the BDF ribbed steel mesh member 2 is prevented from continuously lifting through the other clamping grooves 414.
In another embodiment of the present invention, a sleeve 415 is installed at the upper end of the guide section 411, one end of the limiting section 413 extends into the sleeve 415 and is slidably connected with the sleeve 415, a spring 416 is installed in the sleeve 415, two ends of the spring 416 are respectively connected with the inner wall of the sleeve 415 and the limiting section 413, and a stop 417 is fixedly connected with the upper surface of the abutting member 33.
Specifically, the length direction of the sleeve 415 is perpendicular to the length direction of the guide section 411, a sliding groove is formed in the sleeve, the guide section 411 is arranged in the sliding groove and forms sliding guide fit with the sliding groove, the spring 416 is arranged in the sliding groove, the elastic force of the spring 416 is greater than that of the first elastic piece 42, so when the rod 41 rotates from the first state to the second state, the first elastic piece 42 contracts under the extrusion of the BDF ribbed steel mesh member 2, the spring 416 still keeps a natural initial state, and the limiting section 413 is driven to slide on the arc surface of the abutting piece 33, so that the connecting rib 43 is limited at one end of the groove 321;
when the displacement adjustment of BDF ribbed steel net member 2 after installing, member 41 drives spacing section 413 and removes the top of conflict piece 33 to in the removal in-process spacing section 413 and dog 417 contact, dog 417 blocks spacing section 413 and continues to remove, and BDF ribbed steel net member 2 still need remove when adjusting, force spacing section 413 to slide in sleeve 415 under the conflict of dog 417, spring 416 begins the shrink this moment, spacing section 413 is located the one end of sleeve 415 and stretches out gradually in sleeve 415, and stretch out to the opening part of mounting groove 31, because the height of guide section 411 is slightly higher than the height of BDF ribbed steel net member 2, so the spacing section 413 that removes to mounting groove 31 opening part just is located the top of BDF ribbed steel net member 2, spacing section 413 at this moment blocks BDF ribbed steel net member 2 from the top, avoid BDF ribbed steel net member 2 to appear rising phenomenon in the concrete pouring in-process.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
