[0054] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0055] In the prior art, formwork is typically secured using fixed brackets, typically made of steel, which provide a certain level of strength and stability. During use, the brackets are first fixed to the ground, then the formwork is placed on them. The height and angle of the brackets are adjusted to ensure the formwork is in the correct position and angle. Finally, the formwork is secured to the brackets using bolts or other fixing methods. This results in a cumbersome, time-consuming, and inefficient process for installing and removing the formwork. The inability to freely adjust the angle of the formwork according to actual needs can, in some cases, affect the progress and quality of construction. Furthermore, the formwork is difficult to carry and store, which presents certain challenges for construction.

[0056] In view of this, the technical solution of the present invention provides a construction engineering template fixing bracket that can be adjusted in angle and is easy to store. Figure 1-3, comprising: a U-shaped base 1, a U-shaped receiving groove is formed inside the U-shaped base 1, and a plurality of fixed piles 21 are connected to the U-shaped base 1; a placement frame, the receiving groove is used to accommodate a placement frame of a rotatable template; the placement frame comprises a first U-shaped frame 3 and a second U-shaped frame 4 with openings arranged opposite to each other, the first U-shaped frame 3 and the second U-shaped frame 4 constitute a template installation area, the first U-shaped frame 3 is rotatably connected to the U-shaped base 1, and the first U-shaped frame 3 pushes the second U-shaped frame 4 to separate from or approach it through the placement frame separation mechanism, thereby increasing or restoring the template installation area.

[0057] In the above embodiment, the fixing stakes 21 can be used to fix the fixing bracket to the required working location, thereby increasing the overall stability of the fixing bracket. The second U-shaped frame is pushed by the frame separation mechanism to change the size of the template installation area. The automated and adjustable design greatly shortens the time for template removal and installation, improving construction efficiency.

[0058] In the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0059] In an embodiment of the present invention, the placement frame separation mechanism includes:

[0060] Separation power unit: a U-shaped cavity 5 is formed in the first U-shaped frame 3; the separation power unit is installed at the bottom of the U-shaped cavity 5;

[0061] The force transmission part is provided on both sides of the bottom of the U-shaped cavity 5 and is connected to the separation power part;

[0062] Driving part, both sides of the second U-shaped frame 4 have installation channels 6, and each installation channel 6 is fixedly connected to a driving part, which is dynamically connected to the force transmission part and pushes the second U-shaped frame 4 in the direction away from the first U-shaped frame 3.

[0063] In the specific embodiment of the present invention, see the attached Figure 4 and 5The separation power unit is a servo motor 7, the driving unit is a movable column 10, and the force transmission unit includes: a pulley 13, a transmission belt 14 and two screw rods. The two screw rods include a first screw rod 8 and a second screw rod 9. Each of the screw rods is threadedly connected to one of the movable columns 10. The two pulleys 13 are fixed on the screw rods. The transmission belt 14 connects the two pulleys 13. The output end of the servo motor 7 is fixedly connected to any one of the screw rods.

[0064] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0065] Advantageously, the inner walls of both sides of the U-shaped cavity 5 are provided with sliding grooves 12 , and the outer walls of the two movable columns 10 are provided with sliders 11 , and the sliders 11 slide in the sliding grooves 12 in a one-to-one correspondence.

[0066] In the above embodiment, the servo motor 7 can drive the first screw rod 8 (or the second screw rod 9, either one of the two screw rods can be selected) to rotate. At this time, the pulley 13 on the first screw rod 8 will rotate accordingly, thereby driving the pulley 13 on the second screw rod 9 to rotate through the transmission belt 14, and the second screw rod 9 will rotate accordingly. The movable column 10 on the first screw rod 8 and the second screw rod 9 will move upward in the slide groove 12. The set slide groove 12 can guide the movement trajectory of the movable column 10 so that the movable column 10 will not rotate with the rotation of the first screw rod 8 and the second screw rod 9, so that the second U-shaped frame 4 can be pushed open. At this time, the construction project template can be taken out from between the first U-shaped frame 3 and the second U-shaped frame 4, so that the construction project template can be easily removed for reuse, thereby reducing the workload of the staff and improving the practicality of the device.

[0067] In another embodiment of the present invention, see the attached Figure 1 The U-shaped base 1 has a storage mechanism 2, and the storage mechanism 2 includes:

[0068] A rotating rod 201 is rotatably connected to the open end of the U-shaped base 1 , the first U-shaped frame 3 is fixed to the rotating rod 201 , and the rotating rod 201 is rotated by an external force;

[0069] A locking portion, wherein one end of the rotating rod 201 has a locking portion;

[0070] A support portion, one end of which is hinged to the U-shaped base 1 , and the other end of which is fixed to the back of the first U-shaped frame 3 .

[0071] In the above embodiment, based on the previous embodiment, a storage mechanism 2 is added, and the first U-shaped frame 3 can be driven to rotate to a suitable position by rotating the rotating rod 201. After it is in place, it is locked and fixed by the locking part and supported by the supporting part.

[0072] See attached Figure 6 and 7 , the locking portion may include:

[0073] A connecting plate 202 is fixed to the U-shaped base 1 near the rotating rod 201; the outer wall of the rotating rod 201 is provided with anti-slip grooves 207;

[0074] A locking member, the locking member at least comprising a T-shaped rod 203, the T-shaped rod 203 passing through the connecting plate 202, and a snap ring 205 fixedly connected to the bottom thereof;

[0075] The gear 206 is fixed to the outer wall of the rotating rod 201 and can be engaged and locked with the inner teeth of the snap ring 205 .

[0076] Advantageously, the locking member further includes a spring 204 , one end of the spring 204 is fixed to the connecting plate 202 , and the other end is fixed to the bottom of the top plate of the T-shaped rod 203 .

[0077] In the embodiments of the present invention, see the attached Figure 6 and 8 , the supporting portion comprises:

[0078] The sphere 209, the middle part of the two frames of the U-shaped base 1 has a groove 208, and each of the grooves 208 is correspondingly installed with a sphere 209;

[0079] First bolts 210 , each of the first bolts 210 passes through the frame of the U-shaped base 1 and the sphere 209 ;

[0080] Support rod 211 , each of the spheres 209 is connected to a support rod 211 , and a support plate 212 is provided at the end of each support rod 211 , and the support plate 212 is fixed to the back of the first U-shaped frame 3 .

[0081] In combination with the above embodiments, a fixing bracket can be obtained which is convenient for adjusting the angle and for installing and removing the fixing template.

[0082] During the support and separation process, first unscrew the first bolt 210 to release the limit on the ball 209. At this time, rotating the ball 209 can disengage the support rod 211 from supporting the first U-shaped frame 3, and then pull the T-shaped rod 203 to release the retaining ring 205 from the limit fixation on the gear 206. Then rotate the rotating rod 201 to make the first U-shaped frame 3 parallel to the U-shaped base 1, and then loosen the T-shaped rod 203. At this time, the spring 204 will drive the retaining ring 205 to rebound through its own elastic potential energy to limit the gear 206, so that the fixed bracket can be stored, thereby improving the practicality of the device. The anti-slip groove 207 provided can facilitate the user to rotate the rotating rod 201.

[0085] The second bolt 17 is connected to the top of the L-shaped plate 15 to fix the second U-shaped frame 4 in the storage state.

[0086] In the above embodiment, after the fixed bracket is stored, the L-shaped plate 15 can be rotated up through the first rotating shaft 16. At this time, the second bolt 17 can be screwed in to limit the second U-shaped frame 4, which can prevent the rotating rod 201 from rotating during carrying and causing the fixed bracket to fall apart as a whole.

[0087] See attached Figure 1 and 8 The servo motor 7 is connected to a switch 18, which is fixed to the U-shaped base 1. The switch 18 has a protective cover 19 rotatably connected to the U-shaped base 1. The protective cover 19 can be rotatably connected to the U-shaped base 1 through a second rotating shaft 20.

[0088] The operation of the servo motor 7 can be controlled by the switch 18, and the protective cover 19 can protect the switch 18 from being damaged by external factors. When the switch 18 needs to be used, the protective cover 19 can be rotated to open.
