Description

Technical Field

[0001] The invention belongs to the field of prefabricated buildings, and particularly relates to a construction device for a docking structure of prefabricated walls. Background Art

[0002] Currently, in order to meet the requirements of environmental protection and high-efficiency house building, prefabricated buildings are becoming more and more popular.

[0003] Prefabricated walls are prefabricated in factories, and steel bars and sleeves connected to the steel bars are embedded in the walls. During the assembly process, a crane is used to lift the prefabricated wall to the upper floor for installation. With the cooperation of workers, the grouting sleeve at the lower end of the wall is nested on the steel bar joint of the floor, and then grout is poured into the sleeve to fixedly connect the sleeve and the steel bar joint. After the cement slurry in the sleeve solidifies, the assembly and installation of the wall are completed.

[0004] The docking and matching between the sleeve on the wall and the steel bar joint on the floor takes a long time, with low efficiency and requires the crane to work for a longer time. At the same time, since the wall is in a suspended state lifted by the crane, there is a risk of the wall falling at any time.

[0005] Currently, there is a shelf technology used on the floor of a building. After the crane lifts the wall to the floor, the wall is placed on the shelf and kept in a vertical state for installation, thus liberating the crane and improving the utilization rate of the crane. However, the vertical wall on the shelf is unstable during installation and is prone to tipping over and causing danger.

[0040] like Figure 1 , 2 As shown in 12, the inner wall of the sleeve 1 has a thread A4 for easy slurry hanging; the rod B13 has a thread B15 for easy slurry hanging.

[0041] like Figure 5 , 7 As shown in FIG. 8 , the base 18 on which the four universal wheels 19 are mounted is symmetrically mounted with four arc guide rails 20, and the swing plate 22 that swings around the arc center axis of the guide rails 20 driven by two motors A31 is provided with four arc rods 25 that slide in a one-to-one correspondence with the guide rails 20; Figure 5 , 10 As shown, a slide plate 32 driven by a motor B37 and used to place a wall panel 39 with a sleeve 1 at the lower end is provided on the swing plate 22 and radially slides along the guide rail 20. The slide plate 32 has a plurality of support plates 33 at the lower end thereof which are perpendicular thereto and do not interfere with the steel bar joints 42 on the floor 41. A pad 38 is provided between the slide plate 32 and the wall panel 39 supported thereon and is used to adjust the axis of the sleeve 1 at the lower end of the wall panel 39 to intersect perpendicularly with the arc center axis of the guide rail 20.

[0042] like Figure 7 , 8 As shown in FIG. 10 , the guide rail 20 has a trapezoidal guide bar A21 , and the trapezoidal guide bar A21 slides in the trapezoidal guide groove A26 on the corresponding arc rod 25 .

[0043] like Figure 5 , 6 As shown, the two motors A31 are respectively installed on two guide rails 20; the output shaft of each motor A31 is transmission connected to the worm 30 installed on the corresponding guide rail 20, the worm 30 is meshed with the worm wheel 29 installed on the corresponding guide rail 20, and the gear A28 on the shaft where the worm wheel 29 is located is meshed with the arc rack 27 on the corresponding arc rod 25.

[0045] like Figure 7 ,9 As shown in Fig. 10, a screw sleeve 35 is provided in the middle of the sliding plate 32. The screw sleeve 35 slides in the chute 24 in the middle of the swing plate 22 and is in threaded cooperation with the screw rod 36 installed on the swing plate 22. The screw rod 36 is in transmission connection with the output shaft of the motor B37.

[0046] The working process of the present invention: In the initial state, the included angle between the swing plate 22 and the base 18 is 45 degrees.

[0047] When it is necessary to use the construction equipment in the present invention to assemble and install the wall panel 39 pre-installed with the sleeve 1 in the present invention on the floor 41, first install a connection structure on each steel bar joint 42 on the floor 41, so that the rod A9 in the connection mechanism 8 is nested and screwed with the steel bar joint 42, so that the hinge axis of the connection mechanism 8 is parallel to the installation position of the wall panel 39, so that the axis of the hinge axis is at the same height as the arc center axis of the guide rail 20 on the construction equipment and the rod B13 of the connection mechanism 8 is in a state of swinging 45 degrees towards the construction equipment.

[0048] Then, place a cushion plate 38 with an appropriate thickness on the sliding plate 32 of the construction equipment according to the thickness of the wall panel 39, so that the axis of the sleeve 1 at the lower end of the wall panel 39 is vertically intersected with the arc center axis of the guide rail 20 after it is placed on the cushion plate 38.

[0049] Lift the wall panel 39 by a crane and place it on the cushion plate 38, so that the support plate 33 at the lower end of the sliding plate 32 supports the wall panel 39 and the gap between the sleeve 1 at the lower end of the wall panel 39 and the support plate 33 is opposite.

[0050] Start the motor B37. The motor B37 drives the sliding plate 32 to slide obliquely upward on the swing plate 22 by a certain amplitude through the screw rod 36 and the screw sleeve 35, so that the lower end of the sliding plate 32 is higher than the upper end of the rod B13 of the connection mechanism 8.

[0051] Push the base 18 towards the steel bar joint 42, so that the sleeve 1 at the lower end of the wall panel 39 is coaxial with the rod B13 of the corresponding connection mechanism 8. Start the motor B37, and the motor B37 drives the sleeve 1 at the lower end of the wall to be nested on the rod B13 of the connection mechanism 8 through a series of transmissions.

[0052] Then, start the two motors A31. The two motors A31 drive the swing plate 22 to swing up to the vertical state through the corresponding worm 30, worm gear 29, gear A28, rack 27 and arc rod 25 respectively. The swing plate 22 drives the wall panel 39 to be vertical through the sliding plate 32 and the cushion plate 38. The sleeve 1 at the lower end of the wall panel 39 drives the rod B13 of the connection mechanism 8 to swing to the vertical state around the hinge axis.

[0053] Next, start motor B37. Motor B37 drives the wall panel 39 to be placed vertically on the floor 41 through a series of transmissions. The sleeve 1 at the lower end of the wall panel 39 is completely nested on the rod A9 of the connecting mechanism 8, and the hinge of the connecting mechanism 8 completely enters the sleeve 1.

[0054] Then, remove the construction equipment from the wall panel 39. After the support plate 33 disengages from the wall panel 39, the wall panel 39 automatically falls onto the floor 41 and completes the connection with the steel bar joint 42. At this time, the hinge of the connecting mechanism 8 is opposite to the grouting port 5 of the sleeve 1. Insert the ferrule 16 into the grouting port 5 and nest it on the rod A9 of the connecting mechanism 8, so that the two slots 17 on the inner wall of the ferrule 16 are nested on the two locking projections 11 of the rod A9, thereby strengthening the hinge of the connecting mechanism 8.

[0055] Next, grout into the sleeve 1 through the grouting port 5. The cement slurry fills the sleeve 1 and finally solidifies to complete the fixed connection between the sleeve 1 and the steel bar joint 42.

[0056] In summary, the beneficial effects of the present invention are as follows: The connecting mechanism 8 in the present invention enables the sleeve 1 at the lower end of the wall to be connected to the steel bar joint 42 on the floor 41 of the floor in an inclined state of the wall to complete the vertical installation of the wall on the floor 41 of the floor.

[0057] The construction equipment in the present invention can connect the sleeve 1 on the inclined wall to the steel bar joint 42 on the floor 41 through the connecting mechanism 8 and finally complete the vertical installation of the wall on the floor 41. The construction equipment supports the inclined wall, reducing the center of gravity of the wall and having high stability, avoiding the danger of the wall tipping over during the installation process. At the same time, the crane is liberated and the utilization rate of the crane is improved.
