[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Although prefabricated buildings can currently be assembled on site using precast cement wall panels to improve construction efficiency, they still have obvious defects that need to be improved after being put into use for a long time, such as: Most of the existing prefabricated wall panels are concrete-cast panels. When installing them, a crane is needed to connect the wall panels vertically with the steel bars at the bottom. However, this method results in that the wall panels are not fixed as a whole after installation, and are only connected by a single steel bar at the bottom. At the same time, there are no connecting parts between two adjacent prefabricated wall panels, which makes it impossible for the prefabricated wall panels in the same direction to form a stable and reliable whole. The subsequent positioning and correction operations by the staff are cumbersome, which cannot meet the current use.

Beneficial Effects

[0015] The present invention provides a prefabricated building structure of assembled building design. Compared with the existing technology, it has the following beneficial effects: (1) The prefabricated building structure of the prefabricated building design can utilize the docking of the left prefabricated wall panel and the right prefabricated wall panel with the concave frame by combining the positioning guide mechanism and the prefabricated wall panel mechanism. First, the rectangular card block is allowed to enter the adjacent concave frame, and then the upper concave frame and the top of the left prefabricated wall panel and the right prefabricated wall panel are lowered and installed. The concave frame, the upper concave frame, the left prefabricated wall panel and the right prefabricated wall panel are locked with each other by the linkage between the structures, so that several left prefabricated wall panels and the right prefabricated wall panels form a stable whole.

The arrangement of these structures can allow the arc surface locking block to enter the right prefabricated wall panel first during the insertion of the first round head plate and the second round head plate, and then the T-shaped separation block moves and squeezes the two arc surface locking blocks, so that the arc surface locking blocks are rotated and separated to engage with the right prefabricated wall panel.

The inclined surface rotating seat 107 and the rotating cross bar 109 are rotatably connected through a damping bearing and will not rotate easily. The left end of the rotating cross bar 109 passes through the first side socket 105 and extends to the left side of the concave frame 101. The end of the rotating cross bar 109 extending to the left side of the concave frame 101 is fixedly connected to a rectangular block 110 through a fixing block. The initial position of the rectangular block 110 is limited on the inner side of the first side socket 105. The rotating cross bar 1 The right end of the upper concave frame 109 is fixedly connected with a positioning gear cylinder 111 through a fixing block, and the two sides of the bottom of the upper concave frame 102 are respectively fixedly connected with a first round head plate 113 and a second round head plate 114 through a fixing block. The first round head plate 113 will first squeeze the second inclined plate 219, and then the second round head plate 114 will squeeze the first inclined plate 211. The middle part of the bottom of the upper concave frame 102 is fixedly connected with a U-shaped plug-in frame 115 used in conjunction with the first upper socket 103 through a fixing block. The lower part of the inner front of the U-shaped plug-in frame 115 is provided with a gear used in conjunction with the positioning gear cylinder 111. A rebound guide rod 117 is slidably installed at the lower rear part of the inner side of the tooth groove 116 and the U-shaped insertion frame 115 through an opening, and the front end of the rebound guide rod 117 is fixedly connected to an arcuate tooth plate 118 used in conjunction with the positioning gear cylinder 111. When the arcuate tooth plate 118 and the tooth groove 116 are engaged with the second spring 112 located on the surface of the rebound guide rod 117 and between the U-shaped insertion frame 115 and the arcuate tooth plate 118, the positioning gear cylinder 111 can only rotate counterclockwise to lock the U-shaped insertion frame 115 to prevent it from rising upward.

[0023] When in use, firstly connect several concave frames 101 horizontally and lay them flat on the ground, then place the left prefabricated wall panel 201 and the right prefabricated wall panel 202 on the inner side of the concave frame 101, and when the left prefabricated wall panel 201 and the right prefabricated wall panel 202 are lowered, the concave arc plug plate 220 is inserted into the inner side of the second upper socket 104, and after the concave arc plug plate 220 enters the inner side of the concave frame 101, the bottom end will squeeze the inclined plane rotating seat 107 under the guidance of the first guide rod 106, so that the inclined plane rotating seat 107 as a whole drives the rotating cross bar 109, the positioning gear cylinder 111 and the horizontal rectangular block 110 to move left, and the left moving The rectangular block 110 passes through the first side socket 105 and enters the interior of the adjacent concave frame 101. At the same time, the positioning gear cylinder 111 moves to the middle of the concave frame 101. After the left prefabricated wall panel 201 and the right prefabricated wall panel 202 are placed, the two opposite L-shaped side hook plates 203 form a rectangular groove, and then the upper concave frame 102 is installed from the top. First, the U-shaped plug-in frame 115 is inserted between the two L-shaped side hook plates 203 to fix the left prefabricated wall panel 201 and the right prefabricated wall panel 202 left and right, front and back. As the U-shaped plug-in frame 115 continues to descend, the bottom end finally passes through the first upper socket 1 03 enters the interior of the concave frame 101, and after the bottom end of the U-shaped insert frame 115 enters the interior of the concave frame 101, the tooth groove 116 and the arc-shaped tooth plate 118 are meshed with the positioning gear cylinder 111 at the same time. When the U-shaped insert frame 115 continues to descend, the tooth groove 116 will drive the positioning gear cylinder 111 and the rectangular block 110 to rotate ninety degrees. The rotated rectangular block 110 is engaged with the rectangular block 110 to lock the two adjacent concave frames 101 and will not be separated from the first side socket 105. When the positioning gear cylinder 111 rotates, the arc-shaped tooth plate 118 is in the shape of arc-shaped teeth, so the positioning gear cylinder 111 is locked. The counterclockwise rotation of the positioning gear cylinder 111 will squeeze the arc-shaped tooth plate 118 to move backward and prevent the arc-shaped tooth plate 118 from rigidly conflicting with the positioning gear cylinder 111. After the U-shaped insertion frame 115 is fully inserted, the positioning gear cylinder 111 uses the engagement of the tooth groove 116 and the arc-shaped tooth plate 118 to lock the U-shaped insertion frame 115. While the upper concave frame 102 descends and docks with the tops of the left prefabricated wall panel 201 and the right prefabricated wall panel 202, the bottom ends of the first round head plate 113 and the second round head plate 114 pass through the third upper socket 205 and extend to the inside of the left prefabricated wall panel 201 and the right prefabricated wall panel 202, respectively.
