[0002] During construction, aluminum formwork is often used for sealing and then poured to shape. After the concrete solidifies, the aluminum formwork needs to be removed for reuse. Generally, it is dismantled by warping the edges, which can easily cause deformation of the edges of the aluminum formwork and requires restoration.

[0003] Based on the above, the currently used demolding device needs to be adapted according to the size of the mold body during installation and then removed. The adaptive effect is not good, the installation is not convenient, and there is a lack of a fast and stable removal structure and a buffering structure during the removal process.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The winding roller is provided to provide a dismantling structure with good adaptive effect, fast and stable. It can be dismantled by winding through mechanical drive. Compared with the warping method, it can avoid deformation of the aluminum template and has better protection. The dismantled aluminum template can be used again. The hole pins on both sides are automatically stretched open by springs, which can achieve adaptive installation and automatic fixation, and the wedge-shaped locking teeth cooperate with the spring rod B to automatically contact the control wheel for one-way locking, which can limit the reversal of the control wheel.

[0029] The front side of the main frame 1 is rotatably provided with a transmission shaft 105 for linking the synchronization shaft 104 and the control wheel 3 , and both ends of the transmission shaft 105 are respectively connected with the synchronization shaft 104 and the control wheel 3 by bevel gear transmission.

[0031] Among them, the main body of the mold remover 2 is a hollow pipe structure, and two square control grooves 201 are opened at the front ends of both sides of the mold remover 2; two groups of hole pins 202 are slidably arranged inside the two ends of the mold remover 2, and the outside of the hole pins 202 is integrally provided with a flange for limiting position, and a sliding seat 203 is fixedly arranged on the front side of the hole pins 202, and the sliding seat 203 slides in the control groove 201; a spring is arranged between the two groups of hole pins 202; the insertion length of the hole pins 202 can be less than the thickness of the aluminum template.

[0032] The rear edge portion of the control wheel 3 is a one-way tooth structure, and the wedge-shaped locking teeth 107 can interlock with the one-way tooth structure.

[0033] like Figure 1-6 As shown, before use, the winding roller 101 is released in advance to ensure that it can be installed when the main support 1 is placed on the ground. After the original bolts of the building aluminum formwork are removed, the mold remover 2 is placed in the building aluminum formwork;

[0034] Press the sliding seats 203 on both sides to shrink the hole pins 202, and then insert the hole pins 202 into the side through holes of the building aluminum template. Figure 3 In the method in the middle, two sets of mold removers 2 are installed, and the center position is kept balanced as much as possible during installation so as to balance the force;

The protective material outside the buffer plate 102 can be replaced with sponge or silicone to provide buffering.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In the utility model, when in use, the winding roller 101 is unwound in advance to ensure that the main frame 1 can be installed when it is placed on the ground. After the original bolts of the building aluminum template are removed, the demoulding device 2 is placed in the building aluminum template, and the sliding seats 203 on both sides are pressed to shrink the hole pins 202, and then the hole pins 202 are inserted into the side through holes of the building aluminum template.

When the tension wire is tightened and the winding is continued, pressure is applied to the aluminum formwork, and the aluminum formwork is pulled out for removal.

[0042] The wedge-shaped locking teeth 107 cooperate with the spring rod B106 to automatically contact the control wheel 3 for one-way locking, limiting the control wheel 3 from reversing. Conversely, the wedge-shaped locking teeth 107 can be pulled out to release the wire. When demoulding, if the building aluminum formwork bounces off, it will hit the buffer plate 102 for buffering. A conformable rubber layer is bonded to the surface of the buffer plate 102 to prevent damage to the building aluminum formwork.
