The transverse driving assembly moves the second support column 2 to move closer to or away from the first support column 1 by moving laterally on the bracket 8, so as to achieve the transverse movement of the inner mold.

[0030] In this embodiment, a stable triangular connection structure is formed between the first support column 1, the adjustable support assembly 3 and the bracket 8, and a stable triangular connection structure is also formed between the second support column 2, the adjustable support assembly 3 and the transverse drive assembly.

[0031] In this embodiment, by arranging both the first supporting column 1 and the second supporting column 2 on the bracket 8, connecting one end of the adjusting support assembly 3 to the first supporting column 1 and the other end to the bracket 8, the adjusting support assembly 3 can be used to adjust the inclination angle of the first supporting column 1 on the bracket 8, thereby achieving the matching of the first supporting column 1 with one side of the inner template; at the same time, the second supporting column 2 is connected to the bracket 8 through the transverse driving assembly, and one end of the adjusting support assembly 3 is connected to the transverse driving assembly and the other end is connected to the second supporting column 2, thereby achieving the matching of the second supporting column 2 with the other side of the inner template; further, the transverse driving assembly makes the second supporting column 2 approach to or move away from the first supporting column 1 by moving laterally on the bracket 8, thereby achieving the transverse movement of the inner template; it has high adjustment flexibility and high versatility, meets the installation and disassembly requirements of inner templates of different types and sizes, and improves the efficiency of demoulding; and the demoulding frame can be reused many times, with high turnover utilization rate.

[0032] like Figure 1 As shown, in this embodiment, a hinge hole 5 and a limit hole 6 are provided at the hinge of the first support column 1 and the bracket 8, and a pin is installed in the hinge hole 5 and the limit hole 6 to fix the first support column 1, the second support column 2 and the bracket 8, and the limit hole 6 is set in the shape of a long hole. When the position of the hinge hole 5 is fixed, the pin is installed at different positions of the long hole of the limit hole 6, which can control the rotation angle of the first support column 1, and / or

Pins are installed in the hinge hole 5 and the limit hole 6 to fix the first supporting column 1, the second supporting column 2 and the bracket 8. The limit hole 6 is set in the shape of a long hole. When the position of the hinge hole 5 is fixed, the pin is installed at different positions of the long hole of the limit hole 6, which can control the rotation angle of the second supporting column 2.

[0034] like Figure 1 As shown, in this embodiment, the adjusting support assembly 3 adopts a threaded adjusting assembly to adjust the inclination angle of the first supporting column 1 or the second supporting column 2 .

[0035] Further, the adjustable support assembly 3 includes an adjusting nut 31, a first adjusting screw 32 and a second adjusting screw 33. Both ends of the adjusting nut 31 are respectively threadedly connected with the first adjusting screw 32 and the second adjusting screw 33, the first adjusting screw 32 is hinged with the bracket 8, and the second adjusting screw 33 is hinged with the first supporting column 1. The adjusting nut 31 is rotated to adjust the connection length of the first adjusting screw 32 and the second adjusting screw 33 on the adjusting nut 31, so as to achieve the overall extension or contraction of the adjustable support assembly 3, thereby changing the inclination angle β of the first supporting column 1 on the bracket 8.

[0036] like Figure 1 As shown, in this embodiment, both ends of the adjusting nut 31 are respectively threadedly connected with the first adjusting screw 32 and the second adjusting screw 33, the first adjusting screw 32 is hinged with the lateral drive assembly, and the second adjusting screw 33 is hinged with the second supporting column 2. The adjusting nut 31 is rotated to adjust the connection length of the first adjusting screw 32 and the second adjusting screw 33 on the rotating adjusting nut 31, so as to adjust the overall extension or contraction of the supporting assembly 3, thereby changing the inclination angle β of the second supporting column 2 on the bracket 8.

[0037] When the support assembly 3 is adjusted to be extended as a whole, the inclination angle β of the first support column 1 and the second support column 2 on the bracket 8 will increase, and the lateral distance between the first support column 1 and the second support column 2 will decrease to meet the installation and removal requirements of the small-sized inner mold. When the support assembly 3 is adjusted to be contracted as a whole, the inclination angle β of the first support column 1 and the second support column 2 on the bracket 8 will decrease, and the lateral distance between the first support column 1 and the second support column 2 will increase to meet the installation and removal requirements of the large-sized inner mold. The demoulding frame of this embodiment can be adjusted according to the inner molds of different sizes, and has a highly universal technical effect.

In other embodiments, the lateral driving member 7 can also be a pneumatic cylinder or an electric push rod, as long as it can drive the slide 4 to drive the second support column 2 and the adjustment support assembly 3 to move smoothly horizontally on the bracket 8.

[0040] like Figure 1 As shown, in this embodiment, the bracket 8 is further provided with a slide groove 41, and the slide seat 4 is slidably connected to the slide groove 41. Driven by the transverse driving member 7, the slide seat 4 reciprocates along the slide groove 41 to drive the second support column 2 and the adjustment support assembly 3 to move laterally on the bracket 8.

[0041] like Figure 2 As shown, in this embodiment, a winch 11 is provided on the side of the bracket 8 , and the winch 11 is used to drag the first formwork 9 and the second formwork 10 to pull the first formwork 9 and the second formwork 10 out of the longitudinal truss 14 .

[0042] like Figure 2 As shown, in this embodiment, rollers 12 and limit frames 13 are also provided at both ends of the bracket 8. The inner template rolls and rubs on the rollers 12, and the limit frames 13 are used to limit the lateral position of the inner template, thereby improving the efficiency of the installation and removal of the inner template.

[0043] When the demoulding frame of this embodiment is used:

[0044] The first step is to shrink the second mold frame 10, and the shrunk second mold frame 10 is pulled out of the prepared longitudinal truss 14 by a winch 11 and pulled onto the demoulding frame;

[0045] The second step is to open the second mold frame 10 in the second supporting column 2 and install a limit pin at the bottom of the second supporting column 2;

[0046] The third step is to use the transverse driving assembly to drive the second supporting column 2 and the adjusting supporting assembly 3 to move transversely on the bracket 8 to realize the movement of the second mold frame 10 and reserve space for demoulding the first mold frame 9;

[0047] The fourth step is to shrink the first mold frame 9, and use the winch 11 to pull out the prepared longitudinal truss 14 from the shrunk first mold frame 9 and pull it onto the demoulding frame;

[0048] The fifth step is to open the first mold frame 9 in the first supporting column 1;

[0049] The sixth step is to remove the limit pin at the bottom of the second support column 2, and use the transverse drive assembly to drive the second support column 2 and the adjustment support assembly 3 to move laterally on the bracket 8 to achieve the second mold frame 10 and the first mold frame 9 to move closer and close the mold.

[0050] After the mold is closed, the inner membrane plate is hoisted and put into the mold again for the next beam making process. In this embodiment, the mold can be closed and demoulded conveniently, which reduces time and liberates construction personnel. During the operation, the construction personnel are not exposed to danger, which reduces the safety of the inner template. The inner template can be moved between different pedestals as needed, which reduces the number of processed templates, saves construction costs, and has a good application prospect.
