DETAILED DESCRIPTION

[0020] Embodiment: see Figs. 1 to 4As shown, a molded plate splicing structure for a rectangular rooftop water tank includes several molded plates 1 constituting the rectangular water tank. Each molded plate 1 has a rectangular outer frame 11 formed around its perimeter, and several mounting holes 12 are formed on the outer frame 11. Adjacent molded plates 1 abut against each other and are fixed together by bolt assemblies. Bolts on the bolt assemblies are inserted into the mounting holes 12 of the bolt assemblies. A reinforcing fastener 2 is provided between every four groups of adjacent molded plates 1 on the rectangular water tank. The reinforcing fastener 2 includes a square main support plate 21, and rectangular positioning frames 211 extending rearward are provided around the main support plate. A T-shaped guide post 22 is inserted into the middle of each side panel of the positioning frame 211. The end of the guide post 22 passes through the positioning frame 211 and is fixed with a right-angled triangular pressing block 23. A wedge block 24 is inserted between the pressing block 23 and the positioning frame 211. A strip-shaped clearance groove 241 is formed on the wedge block 24. The guide post 22 is inserted into the clearance groove 241 of the wedge block 24. The side of the pressing block 23 near the wedge block 24 is formed with an inclined guide surface 231. One end face of the wedge block 24 abuts against the guide surface 231 of the pressing block 23, and the other end face abuts against the inner wall of the positioning frame 211.

[0021] The front side of the main support plate 21 is provided with a circular locking plate 26. A T-shaped connecting post 25 is inserted into the outer ring of the locking plate 26. The end of the connecting post 25 passes through the main support plate 21 and is inserted and fixed on the wedge block 24. A locking bolt 27 is screwed into the middle of the locking plate 26. The end of the locking bolt 27 presses against the main support plate 21.

[0022] The positioning frame 211 has slots 212 formed between adjacent panels. The outer frame 11 of the molding plate 1 is inserted into the slots 212 of the positioning frame 211. The pressing blocks 23 in the positioning frame 211 press against the inner sidewalls of the corners of the outer frame 11.

[0023] The wedge 24 is in the shape of a right trapezoid. The inclined surface of the wedge 24 abuts against the guide surface 231 of the holding block 23. The side of the clearance groove 241 on the wedge 24 is parallel to the central axis of the connecting post 25. The width of the clearance groove 241 is equal to the diameter of the guide post 22, so that the problem of jamming will not occur.

[0024] The distance from the front side of the guide surface 231 on the pressing block 23 to the positioning frame 211 is less than the distance from the rear side of the guide surface 231 to the positioning frame 211.

[0025] The mounting connection holes 12 on the molding plate 1 are linearly and evenly distributed on the outer frame 11. When adjacent molding plates 1 abut together, the mounting connection holes 12 on the molding plate 1 are matched.

[0026] The distance from the rear end face of the positioning frame 211 to the rear end face of the main support plate 21 is greater than the length of the socket 212 on the positioning frame 211, so that the wedge block 24 is moved forward to press the pressing block 23 to be pressed on the corner of the outer frame 11.

[0027] The slot width of the socket 212 on the positioning frame 211 is equal to twice the thickness of the outer frame 11 on the mold pressing plate 1.

[0028] Working principle: the structure is a mold pressing plate splicing structure on the roof unit rectangular water tank, the existing roof unit rectangular water tank is spliced by a piece of mold pressing plate 1, the splicing is mainly connected through the bolt assembly, but the corner of the mold pressing plate 1 cannot adopt the bolt assembly, so the reinforcing fastener 2 of the structure is designed.

[0029] At this time, the socket 212 on the main support plate 21 is opposite to the outer frame 11 at the adjacent position, then the outer frame 11 is inserted into the socket 212, and the pressing block 23 is inserted into the corner of the outer frame 11, then the locking bolt 27 is rotated to move the locking plate 26 forward, the wedge block 24 is moved forward under the traction of the connecting column 25, the wedge block 23 is obliquely moved under the pressure of the wedge block, and the corner of the mold pressing plate 1 can be effectively prevented from leaking under the diagonal clamping action of the four pressing blocks 23.

[0030] The embodiments are used to illustrate the utility model, and are not used to limit the utility model. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the utility model, so the protection scope of the utility model should be as listed in the claims of the utility model.
