When, worker enters inside box beam, and most of box beam inner space is smaller, and the working environment of workers is poor, and it is inconvenient to remove, and safely
Property is low, influences work efficiency, therefore in the examples below, the utility model can solve above technical problem.
Embodiment one, the utility model are a kind of drawing and pulling type box girder inner formwork, including left half module 1 and right half module 2, left half module 1
Identical with right 2 structure of half module, both are not integrally connecteds, be it is separable be detachably connected, left half module 1 and right half module 2 are unfolded
Afterwards, the upper and lower ends of both are docked to together, and then multiple fixed plates 3 through longitudinal arrangement are fixed together, make both into
For an entirety, and then it is used for casting concrete, wherein, left half module 1, which includes, to be the upper left half module 4 of L-type and is under L-type
Left half module 5, upper left half module 4 and bottom left half module 5 connect through the first hinge 6, make to rotate between the two, the structure of right half module 2
Structure with left half module 1 be it is identical, right half module 2 include be L-type upper right half module 7 and bottom right half module 8, upper right 7 He of half module
Bottom right half module 8 is connected through the second hinge 9, and multiple are respectively and fixedly provided with the inside of the lateral part of upper left half module 4 and upper right half module 7
Three hinges 10, are respectively and fixedly provided with multiple 4th hinges 11 on the inside of the lateral part of bottom left half module 5 and bottom right half module 8, and the 3rd closes
Connected between 10 and the 4th hinge 11 of page through closing device 12.
Embodiment two, on the basis of embodiment one, closing device 12 includes upper plate 13 and lower plate 14, upper plate 13 and
Three hinges 10 form rotation connection, and 14 and the 4th hinge 11 of lower plate forms rotation connection, and upper plate 13 and lower plate 14 are also to turn
Dynamic connection, because there is multiple closing devices 12 in a longitudinal direction, therefore, and has the connection of multiple upper plates 13 and lower plate 14,
Link slot 15 is installed in the junction, U-shaped drag hook 16 is fixed with the termination of link slot 15.
Embodiment three, on the basis of embodiment two, 13 and the 3rd hinge 10 of upper plate, 14 and the 4th hinge 11 of lower plate, on
Rotation connection mode between plate 13 and lower plate 14 has a variety of, and the utility model uses 17 connection mode of bolt, which connects
It not is fixed dead connection to connect, but bolt 17 can be rotated in its junction, and the nut on bolt 17 is used for carrying out it
Connection fixation is indiscrete, but rotation that can be between the two.
Example IV, on the basis of embodiment one, fixed plate 3 when left half module 1 and right half module 2 are fixed, Gu
Fixed board 3 has fixed plate 3 above and below left half module 1 and right half module 2, and has multiple, is with the 3rd hinge the 10, the 4th
The quantity of hinge 11 is corresponding.The composition of fixed plate 3 be by there is two vertical plates 18 on one of half module, such as right half module 2,
There is gap in centre, there is two L-type plates 19 on left half module 1, and there is gap in centre, and snap-gauge is rotatably connected in two vertical plates 18
20, the other end of snap-gauge 20 is pressed in two L-type plates 19, is finally fixed with bolt.
Embodiment five, in order to preferably support and fix left half module 1 and right half module 2, be placed with it multiple transverse directions and
