Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-5 A concrete fixing frame for construction includes a base 1 and a bottom plate 2 arranged above the base 1, a supporting leg 10 is provided on the lower side of the bottom plate 2, and the bottom plate 2 is installed on the upper end of the supporting leg 10; a rotatably connected supporting frame 3 is provided on the upper side of the bottom plate 2, and a top plate 11 is provided between the bottom plate 2 and the supporting frame 3; a supporting column 4 is fixedly installed on the outer side of the bottom plate 2, and a threaded rod 8 is threadedly connected at the upper end of the supporting column 4; a first side plate 6 and a second side plate 7 that are rotatably connected are respectively provided on the outer side of the supporting frame 3, and one end of the threaded rod 8 is rotatably connected to one side of the corresponding first side plate 6 and second side plate 7 respectively; a fixing member 5 is fixedly installed on one end of the supporting frame 3.

[0023] Among them, a transparent plastic film used for concrete construction is first laid inside the support frame 3, and the plastic film is fixed to the inside of the support frame 3 by a fixing member 5. One end of the threaded rod 8 fixes the first side plate 6 and the second side plate 7 to the outside of the support frame 3, so as to facilitate the removal of the concrete slab from the support frame 3.

[0024] A hydraulic cylinder 13 is installed on the upper side of the base 1 , and a top plate 11 is fixedly installed on the output end of the hydraulic cylinder 13 , and the top plate 11 passes through the bottom plate 2 and the support frame 3 in sequence.

[0025] The hydraulic cylinder 13 is used to move the top plate 11 so that the top plate 11 pushes the solidified concrete slab out from the inside of the support frame 3, making it easier to take out the solidified concrete slab.

[0026] A connector 14 is provided on one side of the first side plate 6 and the second side plate 7 , and one end of the threaded rod 8 is rotatably connected to the connector 14 . A swivel 9 is fixedly installed on one end of the threaded rod 8 , and the swivel 9 is located on one side of the support column 4 .

[0027] Among them, the threaded rod 8 rotates at the upper end of the support column 4, and a threaded hole used in conjunction with the threaded rod 8 is opened at the upper end of the support column 4. The threaded rod 8 rotates and moves in the horizontal direction, and is connected to the inside of the connecting head 14, which is used to support the corresponding first side panel 6 and the second side panel 7, and the template can be reinforced.

[0028] An opening is provided at the upper end of the fixing member 5, and a fixing pad 17 is provided on the inner wall of the fixing member 5; a fixing spring 18 is provided between the upper side of the fixing pad 17 and the inner wall of the fixing member 5, and the two ends of the fixing spring 18 are fixedly connected to the upper side of the fixing pad 17 and the inner wall of the fixing member 5 respectively.

[0029] When the plastic film is laid inside the support frame 3, it is fixed on the fixing member 5. The fixing pad 17 inside the fixing member 5 is fixed to the plastic film through the fixing spring 18, so that when the concrete solidifies, it will not stick to the formwork in the support frame 3 and is easy to remove.

[0030] A fixing column 16 is fixedly installed on the upper side of the fixing pad 17, and the upper end of the fixing column 16 passes through the upper end of the fixing piece 5; the fixing column 16 is located inside the fixing spring 18, and a handle 15 is fixedly installed on the upper end of the fixing column 16; the handle 15 is arranged above the fixing piece 5.

[0031] Among them, manually pulling the handle 15 drives the fixing column 16 to drive the fixing pad 17 to move vertically, which can compress the fixing spring 18. At this time, the transparent film can be placed, and the handle 15 is released. The fixing pad 17 and the fixing column 16 are reset through the fixing spring 18, which will fix the plastic film.

[0032] A support pad 12 is provided at the lower side of the top plate 11 and the output end of the hydraulic cylinder 13 . The support pad 12 is installed at the output end of the hydraulic cylinder 13 and the lower side of the top plate 11 .

[0033] Among them, the hydraulic cylinder 13 is connected through the support pad 12 at its output end to drive the top plate 11 to move vertically. When the concrete slab cannot be taken out of the support frame 3, the hydraulic cylinder 13 drives the top plate 11 to move vertically, so that it can push the concrete slab out of the support frame 3, which is convenient for recovering the concrete slab.

[0034] Working principle: A transparent plastic film used for concrete construction is first laid inside the support frame 3, and the plastic film is fixed to the inside of the support frame 3 with a fixing part 5. When the plastic film is laid inside the support frame 3, it is fixed on the fixing part 5, and the fixing pad 17 inside the fixing part 5 is fixed to the plastic film through the fixing spring 18. One end of the threaded rod 8 fixes the first side plate 6 and the second side plate 7 to the outside of the support frame 3. The threaded rod 8 rotates and moves in the horizontal direction, and is connected to the inside of the connecting head 14 to support the corresponding first side plate 6 and the second side plate 7. The formwork can be reinforced. When the concrete slab cannot be taken out of the support frame 3, the top plate 11 is driven to move vertically by the hydraulic cylinder 13, so that it pushes the concrete slab out of the support frame 3, which is convenient for recovering the concrete slab.
