The positive angle fixing units 2 include a first fixing plate 21, a second fixing plate 22 and a fixing beam 23. The first fixing plate 21 and the second fixing plate 22 are respectively arranged at the left and right ends of the main template 1. The fixing beam 23 is arranged between the first fixing plate 21 and the second fixing plate 22, and abuts against the end surface of the main template 1. There are fixing beams between the first fixing plate 21 and the fixing beam 23, and between the second fixing plate 22 and the fixing beam 23. Locking rod 24; a slot 25 is provided inside the first fixing plate 21 and the second fixing plate 22, the top of the slot 25 is provided with an opening 251, the fixed beam 23 is provided with a first through hole, the fixed locking rod 24 includes a straight rod portion 241 and a bent portion 242, the bent portion 242 is arranged at an angle of 15 to 40 degrees with the straight rod portion 241, and the straight rod portion 241 is provided with an external thread; the bent portion 242 of the fixed locking rod 24 is obliquely inserted into the slot 25 through the opening 251, the straight rod portion 241 of the fixed locking rod 24 passes through the first through hole of the fixed beam 23, and the fixed beam 23 is provided with a locking structure 3 for fixedly connecting with the straight rod portion 241 of the fixed locking rod 24.
[0018] In this embodiment, the first fixing plate 21 and the second fixing plate 22 are firstly arranged at the left and right ends of the main template 1, respectively, and the first fixing plate 21 and the second fixing plate 22 are tightly fitted with the main template 1, and then the bent portion 242 of the fixed locking rod 24 is obliquely inserted into the slot 25 through the opening 251, and then the fixed crossbeam 23 is assembled, and the fixed crossbeam 23 abuts against the end surface of the main template 1; because the bent portion 242 of the fixed locking rod 24 is obliquely inserted into the slot 25, a clamping relationship is formed between the bent portion 242 of the fixed locking rod 24 and the first fixing plate 21, ensuring that the bent portion 242 of the fixed locking rod 24 will not be separated from the slot 25 due to the weight of the first fixing plate 21 itself, ensuring that the fixed locking rod 24 is tightly connected to the first fixing plate 21 (The connection structure of the fixed locking rod 24 is the same as that of the first fixed plate 22), after the straight rod portion 241 of the fixed locking rod 24 passes through the first through hole of the fixed beam 23, the locking structure 3 is used to ensure that the fixed locking rod 24 is tightly connected to the fixed beam 23; after the assembly is completed, the first fixed plate 21, the second fixed plate 22 and the fixed beam 23 cannot be loose, and the utility model uses the first fixed plate 21, the second fixed plate 22 and the fixed beam 23 to press the main formwork 1 from three directions to ensure that the main formwork 1 is tightly fitted to the concrete wall column, and there will be no leakage at the joints, and the first fixed plate 21, the second fixed plate 22, the fixed locking rod 24 and the fixed beam 23 are easy to assemble and disassemble, and can be used repeatedly.
[0019] In this embodiment, the locking structure 3 includes a gasket 31 and a locking nut 32. A second through hole is provided in the middle of the gasket 31. An inner ring of the locking nut 32 is provided with an internal thread. The locking nut 32 is threadedly connected with the straight rod portion 241 of the fixed locking rod 24. After the straight rod portion 241 of the fixed locking rod 24 passes through the first through hole of the fixed crossbeam 23 and the second through hole of the gasket 31 in sequence, one end of the gasket 31 abuts against the fixed crossbeam 23, and the other end of the gasket 31 abuts against the end face of the locking nut 32. The locking is performed by a locking screw sleeve 32, and two baffles 321 are arranged on the outer circumference of the locking screw sleeve 32. The two baffles 321 are arranged in an array along the central axis of the locking screw sleeve 32. After the locking screw sleeve 32 is locked, the gasket 31 fits tightly against the fixed beam 23 to prevent loosening. The baffle 321 has two functions: 1. It is convenient for the operator to rotate the locking screw sleeve 32; 2. After the locking screw sleeve 32 is locked, the baffle 321 can prevent the straight rod portion 241 of the fixed locking rod 24 from detaching from the gasket 31 and the fixed beam 23.
[0020] In the best implementation mode of the present utility model, the bending portion 242 and the straight rod portion 241 are arranged at an angle of 25 degrees. If the bending angle of the bending portion 242 in this embodiment is too small, the bending portion 242 cannot be inserted into the slot 25; if the bending angle of the bending portion 242 is too large, it is easy to detach from the slot 25, and it is impossible to ensure that the fixed locking rod 24 is tightly connected to the first fixed plate 21.
[0021] In this embodiment, the straight rod portion 241 and the bent portion 242 of the fixed locking rod 24 are integrally formed to ensure the rigidity and stability of the fixed locking rod 24, so that it can withstand the pressure brought by the first fixed plate 21 or the second fixed plate 22 and the fixed beam 23, and prevent the straight rod portion 241 and the bent portion 242 of the fixed locking rod 24 from breaking.
[0022] In this embodiment, a reinforcing rib 243 is provided between the straight rod portion 241 and the bent portion 242 of the fixed locking rod 24 to increase the strength of the bent portion 242 and to increase the service life of the fixed locking rod 24 .
[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
