TECHNICAL FIELD

[0001] The utility model relates to the field of engineering construction especially steel reinforced concrete component template fastening device. BACKGROUND

[0002] Steel reinforced concrete component template fastening device is a kind of equipment for fixing steel reinforced concrete component template in building construction, prevent template from deformation, displacement or swelling etc. due to the lateral pressure of concrete in the process of concrete pouring, ensure that template can keep stable shape and position, so as to ensure that the size and shape of concrete component meet the design requirements.

[0003] The existing steel reinforced concrete component template fastening device lacks the function of adjusting the included angle, and because of the lack of angle adjustment function, the fastening device cannot adjust the angle, so it cannot closely adhere to the outer surface of the cement column, so that when facing the polygonal cement column, the fastening device can only maintain a fixed straight line or a single angle bending state, which will cause the template to appear gap or excessive extrusion at the corner of the column when installing the template.

[0004] Therefore, in view of the above-mentioned problems of the existing steel reinforced concrete component template fastening device lacking the function of adjusting the included angle, and when facing the polygonal cement column, the fastening device can only maintain a fixed straight line, which will cause the template to appear gap or excessive extrusion at the corner of the column, a steel reinforced concrete component template fastening device can be designed, by setting up screw No. CONTENT OF THE UTILITY MODEL

[0005] In order to overcome the problem of the existing steel reinforced concrete component template fastening device lacking the function of adjusting the included angle, and when facing the polygonal cement column, the fastening device can only maintain a fixed straight line, which will cause the template to appear gap or excessive extrusion at the corner of the column.

[0006] The technical solution of this utility model is as follows: a formwork fastening device for reinforced concrete components, including a sliding frame; it also includes a mounting plate 1, a screw rod 2, a limiting plate, a nut and a baffle. A moving component is provided inside the sliding frame. Two symmetrical mounting plates 1 are provided on the right side of the front surface of the sliding frame and the front surface of the moving end of the moving component. A screw rod 2 is rotatably connected between the two mounting plates 1. A limiting plate is provided on the upper surface of the screw rod 2. A nut is connected to the lower side of the outer surface of the screw rod 2. A baffle is installed through the middle of the outer surface of the screw rod 2.

[0007] Preferably, by setting a second lead screw, which is rotatably connected to the first mounting plate, the baffle rotates during rotation. This, combined with the sliding frame, forms an angle. A nut and a limiting plate are then used. When the lower surface of the limiting plate is in contact with the upper surface of the first mounting plate, the nut is continuously turned upwards until the upper surface of the nut is in contact with the lower surface of the first mounting plate, thus locking the rotation angle of the baffle. This achieves the purpose of adjusting the angle, solving the problem that existing reinforced concrete formwork fastening devices lack the function of adjusting the angle. Because of this lack of angle adjustment, and the fact that the fastening device cannot adjust the angle between the sides of a polygon, it cannot tightly fit the outer surface of the concrete column. Consequently, when facing a polygonal concrete column, the fastening device can only maintain a fixed straight line or a single angle of bending, leading to gaps or excessive compression at the column corners during formwork installation.

[0008] Preferably, the moving component includes a knob, a lead screw, and a sliding mounting block; a knob is provided at the middle position of the left surface of the sliding frame, the right surface of the knob passes through the left surface of the sliding frame and is connected to the lead screw, the right surface of the lead screw is rotatably connected to the inner right surface of the sliding frame, the outer surface of the lead screw is threadedly connected to the sliding mounting block, and the front surface of the sliding mounting block is connected to the rear surface of the mounting plate.

[0009] Preferably, a rocker arm is provided on the left surface of the knob, and a crank handle is rotatably connected to the left surface of the rocker arm away from the knob.

[0010] Preferably, a second mounting plate is provided on the lower side of the left surface of the sliding frame. A bolt is threaded through the lower surface of the second mounting plate. A movable plate is rotatably connected to the upper surface of the bolt. The right surface of the movable plate is in contact with the left surface of the sliding frame. A fixed plate is installed on the left surface of the sliding frame above the knob. The lower surface of the fixed plate is in contact with the upper side of the outer surface of the knob.

[0011] Preferably, the rear surface of the sliding frame is provided with three rubber plates, and a reflector is installed on the rear surface of the rubber plates.

[0012] Preferably, both baffles are provided with anti-slip pads on their opposite surfaces, and the anti-slip pads are made of rubber.

[0013] Preferably, magnetic plates are provided on both the upper and lower surfaces of the sliding frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a second lead screw, which is rotatably connected to the first mounting plate, the baffle rotates during rotation. This, combined with the sliding frame, forms an angle. A nut and a limiting plate are then installed. When the lower surface of the limiting plate is in contact with the upper surface of the first mounting plate, the nut is continuously turned upwards until the upper surface of the nut is in contact with the lower surface of the first mounting plate, thus locking the rotation angle of the baffle. This achieves the purpose of adjusting the angle, solving the problem that existing reinforced concrete formwork fastening devices lack the function of adjusting the angle. Because of this lack of angle adjustment, and the fact that the fastening device cannot adjust the angle between the sides of a polygon, it cannot tightly fit the outer surface of the concrete column. Consequently, when facing a polygonal concrete column, the fastening device can only maintain a fixed straight line or a single angle of bending, leading to gaps or excessive compression at the column corners during formwork installation.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a formwork fastening device for reinforced concrete components, including a sliding frame 1; it also includes an installation plate 3, a screw rod 4, a limiting plate 5, a nut 6, and a baffle 7. A movable component is provided inside the sliding frame 1. Two symmetrical installation plates 3 are provided on the right side of the front surface of the sliding frame 1 and the front surface of the moving end of the movable component. A screw rod 4 is rotatably connected between the two installation plates 3. A limiting plate 5 is provided on the upper surface of the screw rod 4. A nut 6 is connected to the lower side of the outer surface of the screw rod 4. A baffle 7 is installed through the middle of the surface. A screw rod 4 is provided. Since the screw rod 4 and the mounting plate 3 are rotatably connected, the baffle 7 will rotate when it rotates. This, together with the sliding frame 1, forms an angle. A nut 6 and a limiting plate 5 are provided. When the lower surface of the limiting plate 5 is in contact with the upper surface of the upper mounting plate 3, the nut 6 is continuously turned upwards until the upper surface of the nut 6 is in contact with the lower surface of the lower mounting plate 3. This locks the rotation angle of the baffle 7, thereby achieving the purpose of adjusting the angle.

[0023] Please see Figures 1-3In this embodiment, the moving component includes a knob 201, a lead screw 202, and a sliding mounting block 203. A knob 201 is positioned at the center of the left surface of the sliding frame 1. The right surface of the knob 201 passes through the left surface of the sliding frame 1 and is connected to the lead screw 202. The right surface of the lead screw 202 is rotatably connected to the inner right surface of the sliding frame 1. The outer surface of the lead screw 202 is threadedly connected to the sliding mounting block 203. The front surface of the sliding mounting block 203 is connected to the rear surface of the mounting plate 3. By rotating the knob 201, the lead screw 202 rotates. When the lead screw 202 rotates, the sliding frame 1 limits the rotation angle of the sliding mounting block 203, thereby causing the sliding mounting block 203 and its connecting parts to move together. This allows the opposing surfaces of the two baffles 7 to tightly adhere to the mold, thus achieving the purpose of securing the mold. A rocker arm 8 is positioned on the left surface of the knob 201, with the left surface of the rocker arm 8 away from the knob 201. A crank handle 9 is rotatably connected to one side of the sliding frame 1. By setting a rocker arm 8, the torque applied to the knob 201 by the operator can be increased. The crank handle 9 also provides a grip point for the operator when turning the rocker arm 8, thus achieving the purpose of easily and conveniently turning the knob 201. A mounting plate 2 10 is set on the lower side of the left surface of the sliding frame 1. A bolt 11 is threadedly connected to the lower surface of the mounting plate 2 10. A movable plate 12 is rotatably connected to the upper surface of the bolt 11. The right surface of the movable plate 12 is in contact with the left surface of the sliding frame 1. A fixed plate 13 is installed on the left surface of the sliding frame 1 above the knob 201. The lower surface of the fixed plate 13 is in contact with the upper surface of the outer surface of the knob 201. By setting the bolt 11, it can be moved upward when the bolt 11 is turned. When the bolt 11 moves upward, it drives the movable plate 12 to move upward, thereby cooperating with the fixed plate 13 to clamp the knob 201, thus achieving the purpose of locking the knob 201.

[0024] Please see Figures 1-4 In this embodiment, three rubber plates 14 are provided on the rear surface of the sliding frame 1, and reflectors 15 are installed on the rear surface of the rubber plates 14. By setting reflectors 15, workers can notice the installed reinforced concrete component formwork fastening device when working at night, preventing collision accidents. Anti-slip pads 16 are provided on the opposite surfaces of the two baffles 7. The anti-slip pads 16 are made of rubber. By setting anti-slip pads 16, the contact friction between the baffles 7 and the mold is increased. Since the anti-slip pads 16 are made of rubber, they have soft properties, thus avoiding hard contact with the mold and protecting the mold. Magnetic suction plates 17 are provided on the upper and lower surfaces of the sliding frame 1. By setting magnetic suction plates 17, the upper and lower reinforced concrete component formwork fastening devices can be connected, thereby enhancing the overall stability.

[0025] During operation, the knob 201 is turned, which drives the lead screw 202 to rotate. The rotation of the lead screw 202 limits the rotation angle of the sliding mounting block 203 via the sliding frame 1, thereby moving the sliding mounting block 203 and its connecting parts together. This allows the opposing surfaces of the two baffles 7 to tightly adhere to the mold, achieving the purpose of securing the mold. The rocker arm 8 increases the torque applied to the knob 201 by the operator, and the handle 9 provides a grip point for the operator when turning the rocker arm 8, making it easy and convenient to rotate the knob 201. The bolt 11 allows for upward movement when rotated. When bolt 11 moves upward, it drives movable plate 12 to move upward, thereby cooperating with fixed plate 13 to clamp knob 201, thus locking knob 201. By setting reflector 15, workers can notice the installed reinforced concrete component formwork fastening device when working at night, preventing collision accidents. By setting anti-slip pad 16, the contact friction between baffle 7 and mold is increased. Since anti-slip pad 16 is made of rubber, it has soft characteristics, thus avoiding hard contact with mold and protecting mold. By setting magnetic suction plate 17, the upper and lower reinforced concrete component formwork fastening devices can be connected, thereby enhancing the overall stability.

[0026] Through the above steps, by setting the second lead screw 4, which is rotatably connected to the first mounting plate 3, the baffle 7 will rotate during rotation. This, combined with the sliding frame 1, forms an angle. Then, by setting the nut 6 and the limiting plate 5, when the lower surface of the limiting plate 5 is in contact with the upper surface of the upper mounting plate 3, the nut 6 is continuously turned upwards until the upper surface of the nut 6 is in contact with the lower surface of the lower mounting plate 3, thereby locking the rotation angle of the baffle 7. This achieves the purpose of adjusting the angle, thus solving the problem that existing reinforced concrete component formwork fastening devices lack the function of adjusting the angle. Due to the lack of angle adjustment function, since there are angles between the sides of the polygon, and the fastening device cannot adjust the angle, it cannot tightly fit the outer surface of the cement column. As a result, when facing a polygonal cement column, the fastening device can only maintain a fixed straight line or a single angle of bending. During the installation of the formwork, gaps or excessive compression may occur at the corners of the column.
