[0002] Prefabricated wallboards are widely used in modern construction, which can improve construction efficiency.

[0003] In the process of connecting two prefabricated wallboards, ensuring the accurate alignment of the wall surface with the wall surface is a key step to ensure the quality and flatness of the building. Here are some common alignment methods and technical measures: 1. Reference line and mark: Before construction, draw an accurate reference line on the foundation or existing structure according to the design drawings. Also mark the corresponding alignment marks on the prefabricated wallboard to ensure that it can be aligned according to the reference line during installation. 2.

[0078] Referring to Figures 13-21 , S4 installs the roof: through the connecting piece of the wall plate 1 and the roof plate 2, the wall plate 1 and the roof plate 2 are connected with each other. After the wall plate 1 is completely connected, the roof plate 2 is connected with the wall plate 1 to form a roof. The wall top connecting strip 82 on the top of the wall plate 1 is slidably connected with the wall-roof connecting piece 7, the roof plate 2 is provided with the fault-tolerant hole 28, the connecting end of the wall-roof connecting piece 7 enters the fault-tolerant hole 28, the worker pushes the roof plate 2, and after the adjacent roof plates 2 are connected with each other, the wall-roof connecting piece 7 is fixedly connected with the top of the wall plate 1 through the sliding positioning piece 74, and then the wall-roof connecting piece 7 is connected with the roof plate 2. The installation of the roof is completed.

[0079] The wall-roof connecting piece 7 is used for connecting the wall plate 1 and the roof plate 2; the sliding positioning piece 74 is used for limiting the relative position of the wall-roof connecting strip 8 and the wall-roof connecting piece 7.

[0080] The wall-roof connecting piece 7 has a threaded rod 71, the threaded rod 71 penetrates through the roof plate 2, and the threaded rod 71 is provided with a nut 73 at the end, which prevents the roof plate 2 from being separated from the wall-roof connecting piece 7.

[0081] The wall-roof connecting strip 8 has a wall-roof connecting groove 821, the sliding positioning piece 74 includes an anti-disengagement block 75 and a sliding positioning bolt 76, the sliding positioning bolt 76 penetrates through the wall-roof connecting piece 7 and is threadedly connected with the anti-disengagement block 75, the anti-disengagement block 75 is located in the wall-roof connecting groove 821 and can slide along the length direction of the wall-roof connecting groove 821, and the wall-roof connecting groove 821 has a bent wall 822 located between the anti-disengagement block 75 and the wall-roof connecting piece 7.

[0082] The wall-roof connecting groove 821 has a slot 823, the width of the slot 823 is greater than the width of the anti-disengagement block 75 and is less than the length of the anti-disengagement block 75.

[0083] The wall-roof connecting piece 7 also has an inclined abutting portion 72, which abuts against the surface of the roof plate 2, which is the back plate 22 in this application.

[0084] The roof board 2 is provided with a fault-tolerant hole 28, the aperture of the fault-tolerant hole 28 is larger than the diameter of the threaded rod 71, and the threaded rod 71 is located in the fault-tolerant hole 28. The fault-tolerant hole 28 is provided with a fault-tolerant cover plate 27 matched with the fault-tolerant hole 28, and the fault-tolerant cover plate 27 is fixedly connected with the roof board 2 through screws.

[0085] One end of the threaded rod 71 penetrates the fault-tolerant cover plate 27, a nut 73 is threadedly connected with the end of the threaded rod, and the circumferential surface of the nut 73 abuts against the fault-tolerant cover plate 27.

[0086] The specific way of installing the roof is as follows: rotating the anti-escape block 75, first, the wall-roof connecting piece 7 is installed into the wall-roof connecting groove 821, then the anti-escape block 75 is rotated again, so that the bent wall 822 of the wall-roof connecting groove 821 is located between the anti-escape block 75 and the wall-roof connecting piece 7, and the sliding positioning screw 76 is slightly rotated, at this time, the anti-escape block 75 abuts against the lower surface of the bent wall 822. The wall-roof connecting piece 7 can be preliminarily fixed on the wall-roof connecting groove 821. Then, the fault-tolerant hole 28 is drilled on the roof board 2, and the roof board 2 is hoisted, so that the fault-tolerant hole 28 can be located directly above the threaded rod 71. Since the aperture of the fault-tolerant hole 28 is much larger than the threaded rod 71, it is convenient and fast to center. After centering, the roof board 2 is lowered, so that the threaded rod 71 can enter the fault-tolerant hole 28.

[0087] The threaded rod 71 can only enter the fault-tolerant hole 28 in the vertical downward manner of the roof board 2, at this time, the assembly structure of the adjacent roof board 2 has not been connected. At this time, the roof board 2 needs to be moved horizontally towards the adjacent roof board 2, so that the two adjacent roof boards 2 are spliced. Moreover, since the wall-roof connecting piece 7 is only preliminarily fixed on the wall-roof connecting groove 821, it can move under a certain external force, so that the side wall of the fault-tolerant hole 28 can fine-tune the wall-roof connecting piece 7 during the horizontal movement of the roof board 2. The threaded rod 71 is always located in the fault-tolerant hole 28.

[0088] After the adjacent roof boards 2 are spliced, the workers move the wall-roof connecting piece 7 in the fault-tolerant hole 28, so that the threaded rod 71 is roughly centered in the fault-tolerant hole 28, and then the hoisting is released, at this time, the bottom of the roof board 2 is supported by the wall board 1, the inclined abutting part 72 and the cross beam 9 respectively.

[0089] Then, the fault-tolerant cover plate 27 is arranged in the fault-tolerant hole 28, the threaded rod 71 penetrates the fault-tolerant cover plate 27, the threaded rod 71 penetrating the fault-tolerant cover plate is threadedly connected with the nut 73, and the nut 73 is tightened, so that the bottom of the nut 73 abuts against the fault-tolerant cover plate 27, thereby enabling the wall-roof connecting piece 7 to connect the wall board 1 and the roof board 2.

[0090] Finally, the sliding positioning screw 76 is tightened, so that the wall-roof connecting piece 7 is further fixedly connected with the wall board 1. The wall-roof connecting piece 7 cannot move relative to the wall board 1. Finally, the roof is installed. DETAILED DESCRIPTION
