Technical Field

[0001] The invention relates to the technical field of waffle board construction, in particular to a waffle board construction device and a construction method. Background Art

[0002] Waffle board is a conventional material used in indoor and outdoor buildings. Its main construction processes include layout, bracket erection, formwork installation, waffle board installation, ribbed beam reinforcement binding, concrete pouring, laser leveling, support frame and formwork removal, etc. Among them, the high-precision leveling of the laser leveling machine is particularly important in the entire construction process.

However, it is not convenient to deal with the convex patterns on the sides of the leveling plate during leveling. In conjunction with the movement of the vehicle body, the existing conventional method is to use a row-by-row leveling method.

A cam 134 is arranged at the top of the telescopic frame 132 extending into the conveying frame 8, and the cam 134 is sleeved on the conveying auger 81. A guide head 136 is fixed on the outer side of the bottom of the telescopic frame 132, and the guide head 136 is located in a guide groove 137. The guide groove 137 is opened on the inner wall of the rotating cylinder 131.

[0041] When the conveying auger 81 rotates, the telescopic frame 132 is driven to expand and contract by the cam 134. Cooperating with the guide head 136 and the guide groove 137, the rotating cylinder 131 is driven to rotate. Furthermore, the side plate 121 can be driven to reciprocate through the gear sleeve 135;

The side plate 121 is embedded and slidably installed at both ends of the baffle 9. A material pushing plate 122 is rotatably installed at the inner side of the rear end of the side plate 121 through a torsion spring. An oil chamber 123 is embedded and opened inside the rear end of the side plate 121. A first piston rod 124 is installed at the inner end of the oil chamber 123, and the first piston rod 124 is connected to the material pushing plate 122. A second piston rod 125 is installed at the outer end of the oil chamber 123, and the outer end of the second piston rod 125 is connected to the outside of the side plate 121 through a spring.

[0044] Embodiment 3

[0045] Based on Example 2, please refer to Figure 1-Figure 7 , the method comprises the following steps:

[0046] S1: The device is moved to the working area by the vehicle body, the screed plate 7 is brought into contact with the ground for leveling operation, and the excess concrete at the rear end is transported by the main auger 61;

[0047] S2: The signal receiver 4 cooperates with the built-in controller to control the oil cylinder 5 to adjust the level of the leveling plate 7. During the leveling process, the excess concrete at the side joints enters the bottom space of the conveyor frame 8;

[0048] S3: The motor drives the conveying auger 81 to rotate, and drives the rotating drum 131 to reciprocate through the cam 134 and the telescopic frame 132, so that the side plate 121 reciprocates, and the state of the push plate 122 is adjusted, and the concrete entering between the push plate 122 and the baffle plate 9 is pushed to the outer end of the conveying auger 81 through the one-way channel at the sealing plate 11;

[0049] S4: The concrete is transported into the auger housing 6 by the transport auger 81 and then transported to the unleveled area on the side by the main auger 61 .

[0050] Specific working steps:

[0051] The horizontal signal is received by the signal receiver 4, and the oil cylinder 5 is controlled by the controller to adjust the horizontality of the screed plate 7. The vehicle body drives the auger shell 6 and the screed plate 7 to move through the mounting frame 1 and the crossbeam 2 to level the concrete floor. At the same time, the main auger 61 is controlled to rotate by the motor to transport the excess concrete at the rear end. In this process, the rear end opening of the bottom of the conveying frame 8 contacts the convex pattern on the concrete floor on the side of the screed plate 7, and the excess concrete is scraped into the conveying frame 8. The concrete is guided to the rear end of the baffle 9 through the inclined pushing plate 122 in the conveying frame 8. The conveying auger 81 is controlled by the motor to rotate in the conveying frame 8. The conveying auger 81 drives the cam 134 to rotate, so that the telescopic frame 132 can cooperate with the second elastic telescopic rod 133 to move up and down under the force. The bottom of the telescopic frame 132 moves in the rotating drum 131, and the guide head 136 and the guide groove 137 drive the rotating drum to rotate. The cylinder 131 rotates, and the gear sleeve 135 on the rotating cylinder 131 drives the side plate 121 to reciprocate. During the movement of the side plate 121, the second piston rod 125 contacts the inclined surface of the resistance block 126, and is forced to move in the oil chamber 123, pushing the first piston rod 124 to move, thereby driving the push plate 122 to rotate, so that the push plate 122 is adjusted from an inclined state to a horizontal state, and the concrete is squeezed toward the baffle 9, so that the sealing plate 11 cooperates with the first elastic telescopic rod 10 to move under force, and the middle cavity of the baffle 9 is released, and the concrete is squeezed to the rear end of the baffle 9, and then the side plate 121 and the push plate 122 are reset, and the sealing plate 11 is reset accordingly to block the baffle 9. Repeating the above operation can gradually squeeze the concrete to the end of the conveying auger 81, and this part of the concrete is conveyed to the auger shell 6 by the rotation of the conveying auger 81, and then conveyed by the main auger 61.
