[0023] The usage process of an electric beam fixture 1 provided in this embodiment is as follows: Place the formwork between the fixed clamping assembly 10 and the movable clamping assembly 20, and move the movable clamping assembly 20 to clamp the beam body with the fixed clamping assembly 10.

[0024] Furthermore, in this embodiment, the fixed clamping assembly 10 includes a fixed clamping plate 11 and a driving unit 12. The bottom end of the fixed clamping plate 11 is connected to the outer wall of the first end close to the driving unit 12. One end of the movable clamping assembly 20 is inserted into the second end of the driving unit 12. The movable clamping assembly 20 is threadedly connected to the driving unit 12, and the movable clamping assembly 20 can move along the driving unit 12.

[0025] Specifically, the first end of the driving unit 12 is disposed opposite to the second end of the driving unit 12.

[0026] Taking Figure 1 the shown orientation as an example, the first end of the driving unit 12 is the left end of the driving unit 12, and the second end of the driving unit 12 is the right end of the driving unit 12.

[0027] Further, in this embodiment, the driving unit 12 includes a fixed sleeve 121, a lead screw 122 and a connecting nut 123. One end of the fixed sleeve 121 away from the movable clamping assembly 20 is provided with a plug plate 1211. A rotating hole is formed in the plug plate 1211. The rotating hole extends along the central axis direction of the fixed sleeve 121 and penetrates the plug plate 1211. The rotating hole is communicated with the fixed sleeve 121. The first end of the lead screw 122 passes through the rotating hole and is inserted into the fixed sleeve 121. The second end of the lead screw 122 extends to the outside along the central axis direction of the fixed sleeve 121. The lead screw 122 can rotate relative to the fixed sleeve 121. The connecting nut 123 is screwed on the second end of the lead screw 122. The connecting nut 123 is welded to the second end of the lead screw 122. The connecting nut 123 is located on the side of the plug plate 1211 away from the fixed sleeve 121. The connecting nut 123 can rotate relative to the plug plate 1211. By rotating the connecting nut 123, the connecting nut 123 drives the lead screw 122 to rotate. The bottom end of the fixed clamping plate 11 is connected to the outer wall of the end of the fixed sleeve 121 away from the movable clamping assembly 20.

[0028] Specifically, one end of the movable clamping assembly 20 is inserted into the end of the fixed sleeve 121 away from the connecting nut 123. The movable clamping assembly 20 is threadedly connected to the first end of the lead screw 122. During the formwork reinforcement construction, a hand drill is connected to the connecting nut 123. The hand drill drives the lead screw 122 to rotate through the connecting nut 123. The rotation of the lead screw 122 drives the movable clamping assembly 20 to move towards the fixed clamping plate 11 to clamp the formwork.

[0029] Among them, the fixed clamping plate 11 is arranged parallel to the central axis direction of the fixed sleeve 121. The central axis of the lead screw 122 is parallel to the central axis of the fixed sleeve 121. In some implementable ways, the central axis of the lead screw 122 coincides with the central axis of the fixed sleeve 121.

[0030] It should be noted that the outer diameter of the connecting nut 123 is larger than the aperture of the rotating hole to prevent the connecting nut 123 from entering the fixed sleeve 121 through the rotating hole.

[0031] Exemplarily, the fixed clamping plate 11 can be connected to the fixed sleeve 121 by welding; of course, the fixed clamping plate 11 can also be connected to the fixed sleeve 121 by bolt connection.

[0032] Further, in this embodiment, the driving unit 12 further includes a limit nut 124. The limit nut 124 is screwed on the lead screw 122. The limit nut 124 is located inside the fixed sleeve 121 and is close to the plug plate 1211.

[0033] Specifically, taking Figure 1 the shown orientation as an example, the limit nut 124 is located on the right side of the plug plate 1211, and the connecting nut 123 is located on the left side of the plug plate 1211.

[0034] It should be noted that the outer diameter of the limit nut 124 is larger than the aperture of the rotating hole.

[0035] Continue to refer to Figures 1 to 3 , in this embodiment, the movable clamping assembly 20 includes a movable clamping plate 21 and a moving unit 22. The bottom end of the movable clamping plate 21 is connected to the outer wall of the first end close to the moving unit 22. The second end of the moving unit 22 is inserted into one end of the fixed sleeve 121 away from the fixed clamping plate 11. The end of the lead screw 122 away from the connecting nut 123 is threadedly connected to the moving unit 22, and the moving unit 22 can move along the fixed sleeve 121.

[0036] Specifically, the first end and the second end of the moving unit 22 are oppositely arranged. Taking the orientation shown in Figure 1 as an example, the first end of the moving unit 22 is the right end of the moving unit 22, and the second end of the moving unit 22 is the left end of the moving unit 22.

[0037] During the formwork reinforcement construction, connect the electric drill to the connecting nut 123. The electric drill drives the lead screw 122 to rotate through the connecting nut 123. The rotation of the lead screw 122 drives the moving unit 22 to move towards the fixed clamping plate 11, so that the fixed clamping plate 11 and the movable clamping plate 21 clamp the formwork.

[0038] Among them, the fixed clamping plate 11 and the movable clamping plate 21 are arranged in parallel and are located in the same plane.

[0039] Exemplarily, both the fixed clamping plate 11 and the movable clamping plate 21 can adopt triangular plates; of course, both the fixed clamping plate 11 and the movable clamping plate 21 can also adopt rectangular plates. In the realizable manner where both the fixed clamping plate 11 and the movable clamping plate 21 adopt triangular plates, both the fixed clamping plate 11 and the movable clamping plate 21 adopt right-angled triangular plates. The long right-angled side of the fixed clamping plate 11 faces the movable clamping plate 21, and the long right-angled side of the movable clamping plate 21 faces the fixed clamping plate 11.

[0040] In this embodiment, both the fixed clamping plate 11 and the movable clamping plate 21 adopt Q500 material, and the surfaces of both the fixed clamping plate 11 and the movable clamping plate 21 are galvanized.

[0041] In the realizable manner where both the fixed clamping plate 11 and the movable clamping plate 21 adopt triangular plates, the thickness range of the triangular plates is 2 mm - 5 mm. In this embodiment, the thickness of the triangular plate is 3 mm, that is to say, the thicknesses of both the fixed clamping plate 11 and the movable clamping plate 21 are 3 mm.

[0042] Furthermore, in this embodiment, the moving unit 22 includes a sliding sleeve 221 and a connecting component 222. An installation opening is formed in the outer top surface near the first end of the sliding sleeve 221. The installation opening extends along the first direction 223 of the sliding sleeve 221 and penetrates the sliding sleeve 221. The connecting component 222 is inserted into the installation opening. Opposite ends of the connecting component 222 extend to the outside along the first direction 223. The bottom end of the movable clamping plate 21 is connected to the outer wall near the second end of the sliding sleeve 221. The first end of the sliding sleeve 221 is inserted into one end of the fixed sleeve 121 away from the connecting nut 123. One end of the lead screw 122 away from the connecting nut 123 is threadedly connected to the connecting component 222. The rotation of the lead screw 122 drives the connecting component 222 to move along the lead screw 122. The connecting component 222 drives the movable clamping plate 21 to move through the sliding sleeve 221 to adjust the distance between the movable clamping plate 21 and the fixed clamping plate 11.

[0043] Exemplarily, both the fixed sleeve 121 and the sliding sleeve 221 can be made of rectangular galvanized pipes; of course, both the fixed sleeve 121 and the sliding sleeve 221 can also be made of round pipes. In the implementation where both the fixed sleeve 121 and the sliding sleeve 221 are made of rectangular galvanized pipes, the first direction 223 of the sliding sleeve 221 is the width direction of the sliding sleeve 221, the second direction 224 of the sliding sleeve 221 is the center line direction of the sliding sleeve 221, and the first direction 223 of the sliding sleeve 221 is perpendicular to the second direction 224 of the sliding sleeve 221.

[0044] In the implementation where both the fixed sleeve 121 and the sliding sleeve 221 are made of rectangular galvanized pipes, taking Figure 1 the shown orientation as an example, the bottom end of the fixed clamping plate 11 is connected to the top surface near the left end of the fixed sleeve 121, and the bottom end of the movable clamping plate 21 is connected to the top surface near the right end of the sliding sleeve 221.

[0045] It should be noted that the width value of the fixed sleeve 121 is greater than the width value of the sliding sleeve 221 so that the sliding sleeve 221 can be inserted into the fixed sleeve 121.

[0046] Among them, the center line of the fixed sleeve 121 is parallel to the center line of the sliding sleeve 221. In some implementable ways, the center line of the fixed sleeve 121 coincides with the center line of the sliding sleeve 221.

[0047] Further, in this embodiment, the connecting component 222 includes a connecting sleeve 2221 and a movable nut 2222. The connecting sleeve 2221 is adapted to the mounting opening. The bottom end of the connecting sleeve 2221 passes through the mounting opening and extends to the outside. The top end of the connecting sleeve 2221 extends to the outside along the first direction 223. Mounting holes are formed on the outer side wall of the connecting sleeve 2221. The mounting holes extend along the second direction 224 of the sliding sleeve 221 and penetrate through the outer wall of the connecting sleeve 2221. The mounting holes are located within the sliding sleeve 221 and are adapted to the movable nut 2222. The movable nut 2222 is inserted through the mounting holes; One end of the lead screw 122 away from the connecting nut 123 is inserted onto the movable nut 2222, and the lead screw 122 is threadedly connected to the movable nut 2222; With such a setting, the movable nut 2222 can be disassembled, replaced, maintained and serviced through the transmission of the lead screw.

[0048] Specifically, the extending direction of the connecting sleeve 2221 is perpendicular to the second direction 224 of the sliding sleeve 221, and the extending direction of the connecting sleeve 2221 is parallel to the first direction 223 of the sliding sleeve 221; The center line of the movable nut 2222 is collinear with the center line of the lead screw 122.

[0049] Exemplarily, the connecting sleeve 2221 is a square tube; Of course, the connecting sleeve 2221 can also be a circular tube.

[0050] Among them, the length value of the connecting sleeve 2221 is greater than the width value of the sliding sleeve 221, thereby preventing the connecting sleeve 2221 from detaching from the sliding sleeve 221 during the movement of the moving unit 22.

[0051] During use, the outer side wall of the connecting sleeve 2221 abuts against the inner side wall of the mounting opening, and the outer side wall of the movable nut 2222 abuts against the inner side wall of the mounting hole, preventing the movable nut 2222 from detaching from the mounting hole during the movement of the moving unit 22.

[0052] Among them, a sealing plate 2211 is provided at the second end of the sliding sleeve 221. The sealing plate 2211 is perpendicular to the center line of the sliding sleeve 221, and the sealing plate 2211 is welded to the sliding sleeve 221.

[0053] It should be noted that the electric beam fixture 1 provided in this embodiment is applicable to the reinforcement of beam bodies with a size of 200 mm to 400 mm. When the beam body on the construction site is too large to be used, the distance between the fixed clamping plate 11 and the movable clamping plate 21 can also be lengthened according to the size of the beam body.

[0054] The using process of the electric beam clamp 1 provided by this embodiment is as follows: When carrying out formwork reinforcement construction, connect the electric drill with the connecting nut 123. The electric drill drives the lead screw 122 to rotate through the connecting nut 123. The rotation of the lead screw 122 drives the movable nut 2222 to move. The movable nut 2222 drives the sliding sleeve 221 to move along the fixed sleeve 121 towards the direction of the fixed clamping plate 11 through the connecting sleeve 2221. The sliding sleeve 221 drives the movable clamping plate 21 to move, so that the fixed clamping plate 11 and the movable clamping plate 21 clamp the formwork.

[0055] The electric beam clamp 1 provided by this application includes a fixed clamping component 10 and a movable clamping component 20; one end of the movable clamping component 20 is inserted into the fixed clamping component 10. The movable clamping component 20 is threadedly connected with the fixed clamping component 10, and the movable clamping component 20 can move relative to the fixed clamping component 10. Compared with the traditional beam side formwork using wooden square as the secondary purlin and double steel pipes as the main purlin, and using water stop screws or through-wall screws to fix the beam side formwork during the construction of concrete structural beams, the construction efficiency is improved and the working hours are saved; it can be operated by one person, saving manpower; it can be reused, saving materials; at the same time, the leakage risk is reduced.
