DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 The present invention includes a first template unit 1, a second template unit 2, a hinge 3, and an adjustable template frame 4. The first template unit 1 and the second template unit 2 are hinged by the hinge 3. The back of the first template unit 1 and the second template unit 2 is provided with an adjustable template frame 4. The adjustable template frame 4 is rectangular and includes four right-angle square tubes 401, two vertically adjustable square tubes 402, and two horizontally adjustable square tubes 403. Each of the vertically adjustable square tubes 402 and each horizontally adjustable square tube 403 can be inserted into the right-angle square tube 401. Both ends of each of the vertically adjustable square tubes 402 and each horizontally adjustable square tube 403 are plugged with right-angle square tubes 401. Each of the vertically adjustable square tubes 402 and each horizontally adjustable square tube 403 is provided with 4 threaded through holes 404.

[0023] The first template unit 1 and the second template unit 2 hinged by the hinge 3 can change the angle between the first template unit 1 and the second template unit 2 so as to be applied to different building parts, and can also facilitate the storage of aluminum templates. The adjustable template frame 4 can change the size of the adjustable template frame 4 by changing the length of the vertical adjustment square tube 402 and the horizontal adjustment square tube 403 inserted in the four right-angle square tubes 401.

[0024] A screw through hole 6 is opened at a right angle position on the front side of the right-angled square tube 401, and first screw through holes 5 are opened at both ends of the front side of the right-angled square tube 401, and screws 405 matched with the first screw through holes 5 are provided, and the screws 405 are threadedly connected with the threaded through holes 404 opened on the vertical adjustment square tube 402 and the horizontal adjustment square tube 403.

[0025] The screw 405 passes through the first screw through hole 5 and is threadedly connected to the threaded through hole 404 provided on the vertical adjustment square tube 402 and the horizontal adjustment square tube 403 , so as to fix the length and width of the adjustable template frame 4 .

[0026] The size, shape and structural composition of the first template unit 1 and the second template unit 2 are axially symmetrical with the hinge 3 as the axis. The first template unit 1 includes a plate surface 101, a plate frame 102, a template connecting through hole 103, and a screw 104. Four screws 104 are distributed in an array on the rear end surface of the plate surface 101. The plate frame 102 is arranged on the rear end surface of the plate surface 101, and a plurality of template connecting through holes 103 are opened on the side of the plate frame 102.

[0027] The plate frame 102 can support the plate surface 101 to make the plate surface 101 more stable. In addition, the plate frame 102 can be connected to the hinge 3 so that the first template unit 1 and the second template unit 2 can be combined to have a larger area and higher construction efficiency. The first template unit 1 and the second template unit 2 are conveniently arranged axially symmetrically with the hinge 3 as the axis, and the first template unit 1 and the second template unit 2 can be folded, buckled and stored. The template connection through hole 103 is reserved for the mutual connection between aluminum templates. The array-distributed screw rods 104 can be adapted to the rectangular adjustable template frame 4. A plate surface 101 can have several threaded rods 104 and can also be installed with several adjustable template frames 4 of different sizes, thereby reducing the cutting and assembly of the plate surface 101.

[0028] The screw through hole 6 is matched with the screw 104, and a nut 406 matched with the screw 104 is installed on the screw 104. The screw through hole 6 on the board surface 101 passes through the screw through hole 6 on the adjustable template frame 4 and then the board surface 101 and the adjustable template frame 4 are fixed with the nut 406. The adjustable template frame 4 changes its size to adapt to boards of different sizes and can enhance the stability of the poured wall.

[0029] The structural form of one side of the plate frame 102 close to the hinge 3 is adapted to the hinge 3, making the entire aluminum template look more beautiful and convenient to store.

[0030] Each right-angle square tube 401 is provided with scale lines, and each vertical adjustment square tube 402 and each horizontal adjustment square tube 403 are provided with scale lines. The scale lines can help construction workers to quickly adjust the adjustable template frame 4 to a suitable size.

[0031] The working principle of the present invention is:

[0032] When in use, the first template unit 1 and the second template unit 2 can be used as a whole template under the connection of the hinge 3. When the angle needs to be adjusted, the first template unit 1 or the second template unit 2 can be manually pulled to change the angle between the two template units and adjusted to the required angle. The upper and lower or left and right sets of aluminum templates are threadedly connected through the template connecting through holes 103, and then the aluminum templates on the same plane are reinforced by the right-angle square tube 401. The aluminum template after the angle adjustment is reinforced with a template square tube with a certain angle. When the size of the template needs to be adjusted, first The nut 406 in the adjustable formwork frame 4 is unscrewed from the fixed screw 104 to separate the adjustable formwork frame 4 from the board surface 101, and then the four screws 405 are unscrewed, and the length of the horizontal adjustment square tube 403 and the vertical adjustment square tube 402 extending into the corresponding right-angle square tube 401 is adjusted, and then the first screw through hole 5 on the right-angle square tube 401 is aligned with the threaded through hole 404 on the corresponding adjustment square tube, and fixed by screws 405, and then the board surface 101 that matches the size of the adjusted adjustable formwork frame 4 is replaced, and the board surface 101 and the adjustable formwork frame 4 are fixed by nuts 406 for use.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
