[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figures 1 to 4 A building stair formwork remover comprises a T-bar 1, a conical surface is arranged at the lower end of the T-bar 1, a through-hole 101 is opened in the middle of the T-bar 1, a lifting mechanism is arranged inside the I-hole 101, and by controlling the lifting mechanism to move downward, the gap between the formwork and the casting surface can be enlarged, and the formwork can be lifted out.

[0018] Preferably, the lifting mechanism includes: a slide groove 104, a slider 2, a slide groove 104 is provided on both sides of the I-shaped hole 101 set on the T-shaped rod 1, a slidable slider 2 is provided inside the slide groove 104, the slider 2 is in a shape of a triangle, and the middle part of the slider 2 is integrally formed and fixedly connected with a connecting rod 201, and one side of the slider 2 is also provided with a rough surface 202 for anti-slipping of the foot, and the lifting mechanism also includes: a lifting rod 3, the diameter of the lifting rod 3 is smaller than the thickness of the T-shaped rod 1, and the lifting rod 3 is divided into two ends, one end is close to the upper part of the T-shaped rod 1, and the other end is close to the conical surface of the lower end of the T-shaped rod 1 A circular hole 301 is opened at the position where the lifting rod 3 is close to the conical surface of the T-shaped rod 1 from the center. The connecting rod 201 of the slider 2 is rotatably sleeved inside the circular hole 301. The lower end of the lifting rod 3 is fixedly connected with a plug column 302. The diameter of the plug column 302 is consistent with the thickness of the T-shaped rod 1. The installation position of the plug column 302 is located at the lower part of the I-shaped hole 101 and the upper end of the T-shaped rod 1. At this time, the conical surface of the lower end of the T-shaped rod 1 will be inserted between the casting surface of the stairs and the template. At this time, by stepping on the rough surface 202 of the slider 2 with your foot, due to the connecting rod on the slider 2 201 is rotatably sleeved with a lifting rod 3, so the sliding block 2 drops and drives the lifting rod 3 to drop, at which time the plug column 302 connected to the lower end of the lifting rod 3 is inserted between the casting surface and the template. Since the diameter of the plug column 302 is consistent with the thickness of the T-bar 1, when the plug column 302 is inserted between the casting surface and the template, the width between the casting surface and the template is expanded. After that, the two L-shaped rotating rods 103 of the T-bar 1 rotate to make the L-shaped rotating rods 103 vertical, and then you can put your hand into the I-shaped hole 101 and And the upper end of the lifting rod 3 is grabbed. Since a circular hole 301 is opened from the center of the lifting rod 3 close to the conical surface of the T-bar 1, and the connecting rod 201 of the slider 2 is rotatably sleeved inside the circular hole 301, when the lifting rod 3 is turned downward with force, the connecting rod 201 of the slider 2 will be used as the fulcrum of the lever, and then the lower end of the lifting rod 3 and the connected column 302 will be lifted, thereby achieving a lever effect, and the column 302 is lifted between the casting surface and the template, thereby achieving separation between the casting surface and the template.

[0019] Preferably: two opposite quarter arc grooves 102 are provided at the place where the I-shaped hole 101 is provided in the middle of the T-shaped rod 1, and a shaft rod is provided on one side of each quarter arc groove 102, and one end of an L-shaped rotating rod 103 is rotatably connected to the shaft rod through a bearing, and the other end of the L-shaped rotating rod 103 is placed inside the quarter arc groove 102. By rotating the two L-shaped rods 103 so that the two L-shaped rods 103 are horizontal to the side of the I-shaped hole 101, the lifting rod 3 can be limited in the T-shaped rod 1.

[0020] Working principle:

[0021] When using, refer to Figure 1, knock on the upper end of the T-bar 1, then the tapered surface of the lower end of the T-bar 1 will be inserted between the casting surface of the stairs and the formwork, at this time, by stepping on the rough surface 202 of the slider 2 with your foot, since the connecting rod 201 on the slider 2 is rotatably sleeved with the lifting rod 3, the slider 2 falls and drives the lifting rod 3 to fall, at this time, the plug column 302 connected to the lower end of the lifting rod 3 will be inserted between the casting surface and the formwork, because the diameter of the plug column 302 is consistent with the thickness of the T-bar 1, therefore when the plug column 302 is inserted between the casting surface and the formwork, the width between the casting surface and the formwork will be expanded, which can solve the problem that the gap between the casting surface and the formwork due to the tapered surface of the lower end of the T-bar 1 is very small or the gap between the casting surface and the formwork is too large. In order to solve the problem of insufficient separation between the two parts, the two L-shaped rotating rods 103 of the T-bar 1 are rotated to make the L-shaped rotating rod 103 in a vertical state. Then, the hand can be put into the I-shaped hole 101, and the upper end of the lifting rod 3 can be grabbed. Since the lifting rod 3 is provided with a circular hole 301 from the center to the position close to the conical surface of the T-bar 1, the connecting rod 201 of the slider 2 is rotatably sleeved inside the circular hole 301, when the lifting rod 3 is rotated downward, the connecting rod 201 of the slider 2 will be used as the fulcrum of the lever, and then the lower end of the lifting rod 3 and the connected plug column 302 will be lifted, thereby realizing the lever effect, and the plug column 302 is lifted between the casting surface and the template, thereby realizing the separation between the casting surface and the template.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
