There is a large gap between the formwork clamps at the corners of beams and columns, and the clamping and limiting force of the formwork at the corners of beams and columns is weak, which can easily lead to bulging of the beams and columns after pouring. Therefore, the present application provides a construction formwork clamp to meet the needs. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A construction template clamp includes a first operating arm and a second operating arm, one end of the first operating arm and the second operating arm are hinged to each other; a pair of sliders are slidably embedded on the first operating arm and the second operating arm, a clamping plate is rotatably assembled on the bottom of the slider, and a driving mechanism for driving the pair of sliders to move toward each other is provided on the first operating arm and the second operating arm.

[0009] Optionally, guide grooves are provided on the side walls of the first operating arm and the second operating arm, and guide protrusions slidably engaged with the guide grooves are provided on the side walls of the sliding block.

[0010] Optionally, a connecting shaft is vertically connected to the bottom of the sliding block, and the clamping plate is mounted on the connecting shaft.

[0011] Optionally, a connecting sleeve is provided on one side of the clamping plate, and the connecting sleeve is rotatably sleeved on the connecting shaft.

[0012] Optionally, an adjustment rail is fixed on the first operating arm, the adjustment rail has a semicircular structure, and the adjustment rail is cocentrically arranged with the hinge axis of the first operating arm and the second operating arm, and the second operating arm is slidably matched with the adjustment rail.

[0013] Optionally, an adjustment slot is provided on the adjustment rail, a guide slide is fixed to the side of the second operating arm away from the first operating arm, the guide slide vertically passes through the adjustment slot, and an angle positioning piece for positioning the second operating arm is provided on the guide slide.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by arranging sliders and driving mechanisms on the first operating arm and the second operating arm, during the formwork support process before casting of building beams and columns, the first operating arm and the second operating arm are horizontally placed above the formwork, and the driving member is used to drive the bidirectional screw to rotate, so that a pair of sliders on the first operating arm and the second operating arm drive the clamping plates to approach each other, so that the two formworks can be clamped close together, so as to facilitate the casting of beams and columns between the two formworks.

The system has high practicality.

Through this structural method, during the template support process before pouring the building beams and columns, the first operating arm 1 and the second operating arm 2 are horizontally placed above the template, and the driving mechanism 5 is used to drive the pair of sliders 3 on the first operating arm 1 and the second operating arm 2 By driving the clamping plates 4 closer to each other, the two templates can be clamped together to facilitate the casting of beams and columns between the two templates. The structure is simple and easy to operate. In addition, the first operating arm 1 and one end of the second operating arm 2 are hinged to each other, and the clamping plates 4 are rotatably connected to the slider 3, so that the first operating arm 1 and the second operating arm 2 can be placed at the corners of the building beams and columns, so that the two pairs of clamping plates 4 are abutted against each other. After driving the slider 3 to drive the clamping plates 4 closer, the templates at the corners of the beams and columns can be effectively clamped, which effectively solves the problem that the clamping gap of the templates at the corners of beams and columns of traditional building template clamps is too large, and the templates at the corners of beams and columns are subject to weak clamping and limiting force, which leads to the phenomenon that the beams and columns are prone to bulging after casting.

[0035] like Figure 1 and Figure 2 As shown, the first operating arm 1 and the second operating arm 2 are both provided with a slide groove 6, the driving mechanism 5 includes a bidirectional screw rod 7 rotatably mounted in the slide groove 6, and the driving mechanism 5 also includes a driving member 8 arranged at the ends of the first operating arm 1 and the second operating arm 2 for driving the slide groove 6 to rotate, the slider 3 is slidably embedded in the slide groove 6 and is threadedly sleeved with the bidirectional screw rod 7, and the bidirectional screw rod 7 is driven by the driving member 8 to rotate, so that the pair of sliders 3 on the first operating arm 1 and the second operating arm 2 can be driven to drive the clamping plate 4 to approach the template for clamping.

[0036] like Figure 1 , Figure 2 and Figure 5As shown, the first operating arm 1 and the second operating arm 2 are provided with guide grooves 11 on their side walls, and the slide block 3 is provided with guide protrusions 19 that are slidably engaged with the guide grooves 11, which are used to limit and guide the slide block 3 to slide along the slide groove 6, so as to prevent the slide block 3 from falling out of the slide groove 6. A connecting shaft 20 is vertically connected to the bottom of the slide block 3, and the clamping plate 4 is installed on the connecting shaft 20. A connecting sleeve 21 is provided on one side of the clamping plate 4, and the connecting sleeve 21 is rotatably sleeved on the connecting shaft 20.

The second operating arm 2 slides along the adjustment rail 9 relative to the first operating arm 1, and the angle between the first operating arm 1 and the second operating arm 2 can be adjusted. The first operating arm 1 and the second operating arm 2 can be positioned at an angle by limiting the angle positioning member 10 to adapt to the clamping of beam-column templates with different angles. Furthermore, one end of the adjustment rail 9 is fixedly connected to the middle of the first operating arm 1, and the other end of the adjustment rail 9 is fixed with a fixing rod 15, and the fixing rod 15 is fixedly connected to the end of the first operating arm 1. A thread is arranged on the outer wall of the top end of the guide slide 17, and the angle positioning member 10 includes a threaded sleeve 18 threadedly sleeved on the guide slide 17.

Furthermore, since one end of the first operating arm 1 and the second operating arm 2 are hinged to each other, and the clamping plate 4 is rotatably connected to the slider 3, the first operating arm 1 and the second operating arm 2 can be placed at the corners of the building beams and columns. The two pairs of clamps 4 are made to abut against each other, and after the driving slider 3 drives the clamps 4, effective clamping of the formwork at the corners of beams and columns is achieved, which effectively solves the problem that the clamping gap of the formwork at the corners of beams and columns of traditional building formwork clamps is too large, and the formwork at the corners of beams and columns is weakly clamped and limited, resulting in the phenomenon that the beams and columns are prone to bulging after pouring. In addition, by utilizing the hinged cooperation of one end of the first operating arm 1 and the second operating arm 2, the second operating arm 2 can slide along the adjusting rail 9 relative to the first operating arm 1, adjust the angle between the first operating arm 1 and the second operating arm 2, and screw the threaded sleeve 18 to tighten it against the adjusting rail 9, so that the first operating arm 1 and the second operating arm 2 can be positioned at an angle, with high flexibility, and can adapt to the clamping of beam and column formworks with different angles.
