[0026] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0027] like Figure 1 、 Figure 2and Figure 3 As shown, the utility model proposes an adjustable beam formwork fixing fixture, including a crossbeam 4, a clamping mechanism 1 and a tensioning assembly 9: wherein, the crossbeam 4 includes an accommodating cavity, in which a pivot 5, a limit member 3 and a pressing elastic member 6 are provided, the pressing elastic member 6 presses against one end of the limit member 3, the pivot 5 is attached to the middle of the limit member 3, and a pressing portion 301 is vertically provided at the other end of the limit member 3; the pressing portion 301 passes through the accommodating cavity; the clamping mechanism 1 includes a movable member 102 embedded in the accommodating cavity from both ends of the accommodating cavity and a clamping member 101 vertically connected to the end of the movable member 102; the movable member 102 can be engaged with the limit member 3; the tensioning assembly 9 is detachably arranged on the clamping member 101.

[0028] The design of the above-mentioned limit member 3 and pivot 5 is based on the principle of lever. The pivot 5 serves as the fulcrum of the lever. By pressing the pressing part 301, the limit member 3 can be rotated around the pivot 5, thereby releasing the engagement between the limit member 3 and the movable member 102, so that the length of the movable member 102 extending into the accommodating cavity can be adjusted as needed; and after releasing the pressing part 301, the limit member 3 is reset under the action of the elastic member 6 and engages with the movable member 102 again to limit the movement of the movable member 102 in the accommodating cavity.

[0029] The above-mentioned clamping members 101 are relatively arranged on both sides of the beam 4 and are used to tighten the side formwork of the beam 10; through the above-mentioned technical solution, the distance between the clamping members 101 can be adjusted so that it can clamp the side formwork 11 of the beam 10 to meet the use requirements of beams 10 of different widths; the above-mentioned tensioning assembly 9 is used to tighten the two clamping members 101, and its own height relative to the clamping member 101 can be adjusted so that it can tighten the clamping member 101 without passing through the beam 10, to meet the use requirements of beams 10 of different heights and improve the overall rigidity of the clamp; the tensioning assembly 9 enables the clamping members 101 to further clamp the side formwork 11, and at the same time makes the clamp as a whole more firmly fixed to the side formwork 11 of the beam 10; the overall structure has high stability and can be applied to the reinforcement of beam formworks of different heights and widths. The formwork reinforcement operation is simple, which improves construction efficiency, and the reinforcement quality is easy to control without affecting the appearance quality of the beam 10.

[0030] As a preferred embodiment, the movable member 102 is provided with a sawtooth track 103 along its length, and the side of the stopper 3 facing the movable member 102 is provided with an engaging portion 302, which can engage with the sawtooth track 103. This allows the length of the movable member 102 extending into the accommodating cavity to be adjusted within the length range of the sawtooth track 103, making the overall operation convenient and efficient.

[0031] Furthermore, the pressing elastic member 6 and the pressing portion 301 are both arranged on a side of the limiting member 3 away from the sawtooth track 103 ; and the pivot 5 is arranged on a side of the limiting member 3 close to the sawtooth track 103 .

[0032] Specifically, such as Figure 1 As shown, both ends of the accommodating cavity are respectively provided with openings, and the movable member 102 extends into the accommodating cavity from the opening and fits against the inner wall of one side of the accommodating cavity, and a sawtooth track 103 is provided on the other side of the movable member 102, and a space sufficient to accommodate the limiting member 3 and the pressing elastic member 6 is provided between the sawtooth track 103 and the inner wall of the other side of the accommodating cavity; the two ends of the limiting member 3 are respectively provided with a pressing portion 301 and a clamping portion 302, wherein the clamping portion 302 faces one side of the sawtooth track 103, and the pressing portion 301 vertically passes through the inner wall of the other side of the accommodating cavity, one end of the pressing elastic member 6 is connected to the inner wall of this side, and the other end is connected to the end of the limiting member 3 close to the clamping portion 302, and at the same time presses The pressure elastic member 6 is in a compressed state. When in use, pressing the pressing portion 301 inwardly causes the end of the limiting member 3 connected to the pressing portion 301 to move toward the side close to the sawtooth track 103. At the same time, the engaging portion 302 moves away from the sawtooth track 103, disengaging from the sawtooth track 103, allowing the movable member 102 to move within the accommodating cavity to adjust the length of the movable member 102 extending into the accommodating cavity. At this time, the engaging portion 302 presses against the pressure elastic member 6. When the pressing portion 301 is released, the engaging portion 302 moves toward the direction close to the sawtooth track 103 under the action of the pressure elastic member 6, engaging with the sawtooth track 103 to limit the movement of the movable member 102. This ensures that the distance between the clamping members 101 matches the distance between the side templates 11 of the beam 10 to be constructed.

[0033] Preferably, the width of the limiter 3 is the same as the width of the accommodating cavity, which can effectively prevent the limiter 3 from moving in the width direction within the accommodating cavity, ensuring that it can rotate around the pivot 5, thereby improving the stability of the overall clamp; the elastic member 6 is preferably a spring.

[0034] In the present application, the length of the accommodating cavity matches the length of the two movable parts 102. When in use, the distance between the two clamping parts 101 can be adjusted by adjusting one of the movable parts 102 or adjusting the two movable parts 102 in sequence.

[0035] Furthermore, the clamping member 101 is disposed on a side of the beam 4 away from the pressing portion 301 to facilitate operation by an operator.

[0036] Furthermore, a partition 7 is provided in the middle of the upper accommodating cavity, which separates the accommodating cavity into a first end and a second end. The movable parts 102 are respectively embedded in the first end and the second end to avoid mutual influence between the two movable parts 102.

[0037] Furthermore, an extrusion elastic member 8 is provided between the movable member 102 and the partition 7. Preferably, the extrusion elastic member 8 is a spring, with its two ends respectively connected to the partition 7 and the movable member 102. The extrusion elastic member 8 is initially in a compressed state. When the pressing portion 301 of the limit member 3 is released, the extrusion elastic member 8 pushes the movable member 102 to move outward from the accommodating cavity, making it easier to adjust the distance between the clamping members 101. When the movable member 102 moves outward a large distance, the extrusion elastic member 8 is transformed into a tensioned state, preventing the movable member 102 from completely falling out of the accommodating cavity, thereby ensuring that the clamp can be used normally.

[0038] Furthermore, the engaging portion 302 is inclined toward the direction approaching the partition 7, and the saw teeth of the sawtooth track 103 are inclined in the same direction as the engaging portion 302. With this design, when the engaging portion 302 is engaged with the sawtooth track 103, the side of the engaging portion 302 close to the partition 7 is in contact with the side of the saw teeth of the sawtooth track 103, which can better clamp the saw teeth and prevent the movable member 102 from moving away from the partition 7, thereby limiting the position of the movable member 102. When it is necessary to further adjust the distance between the clamping members 101 to reduce it, the clamping member 101 is pushed toward the partition 7, and the movable member 102 can move along the inclined direction of the saw teeth under the action of the thrust, without having to release the pressing portion 301 and then adjust the extension length of the movable member 102. This achieves unidirectional movement of the movable member 102, makes the adjustment process more convenient and easy to operate, and improves the reliability of the clamp.

[0039] In a preferred embodiment, Figure 2 As shown, the clamping member 101 is provided with an elongated hole along its length, and the tie assembly includes a screw 902 and a fastener 903. The ends of the screw 902 are fixed to the elongated hole by the fasteners 903. By fixing the screw 902 at different positions along the length of the elongated hole, the distance between the screw 902 and the beam 10 can be adjusted. Thus, the position of the screw 902 can be flexibly adjusted according to the height of the beam 10, so that the clamping member 101 generates the optimal tensile stress on the side formwork 11 of the beam 10, making the side formwork 11 more securely fixed and enhancing the stability and integrity of the entire clamp.

[0040] Furthermore, the clamping member 101 is sleeved with a gasket 901, and the gasket 901 is provided with a hole. The hole of the gasket 901 and the long hole of the clamping member 101 form a through hole, and the screw 902 passes through the through hole and is fixed to the outside of the gasket 901 by a fastener; by providing the gasket 901, the screw 902 is more firmly fixed to the set position of the long hole; by screwing the fastener 903, the clamping members 101 can be brought closer to each other, so that they can firmly fix the side template 11.

[0041] Specifically, by screwing the fastener 903, the clamping member 101 moves toward the other clamping member 101, thereby driving the movable member 102 to move relative to the limiting member 3, thereby realizing convenient adjustment of the distance between the clamping members 101; the fastener 903 is preferably a nut.

[0042] Furthermore, if Figure 3 As shown, the beam formwork fixing fixture proposed in this application also includes a butterfly bolt 2. The accommodating cavity and the movable part 102 are provided with corresponding screw holes. The butterfly bolt 2 passes through the screw hole to fix the movable part 102. When the fixture is not in use, the movable part 102 is fixed by the butterfly bolt 2, which facilitates transportation of the fixture. When the fixture is in use, the butterfly bolt 2 is removed to facilitate adjustment of the distance between the clamping parts 101.

[0043] In a specific embodiment, the butterfly bolt 2 is arranged on the same side as the pressing portion 301 to facilitate use by an operator.

[0044] The present application also proposes a beam template fixing method, using the beam template fixing fixture as described above, such as Figure 4 As shown, the following steps are included:

[0045] S1. Remove the butterfly bolt 2 and press the pressing portion 301 to release the engagement restriction of the limiter 3 on the movable member 102. The two movable members 102 are moved toward the outside of the accommodating cavity under the pressure of the extrusion elastic member 8, thereby increasing the distance between the clamping members 101 so that the distance between the clamping members 101 is slightly larger than the distance between the two side templates 11 of the beam 10 to be constructed.

[0046] During the adjustment process, the worker holds the two clamping members 101 to better control the distance between the two clamping members 101 to meet the requirements;

[0047] S2. Release the button to reset the limiting member 3 under the action of the elastic member 6, clamping the movable member 102;

[0048] S3, set up the beam template fixing fixture above the beam 10 template, so that the clamping parts 101 are located on both sides of the side template 11 of the beam 10;

[0049] In this embodiment, a wall is provided below the beam 10 to be constructed, so formwork is provided above and on both sides of the beam 10, and a beam formwork fixing fixture is mounted on the upper portion of the formwork above the beam 10; a wooden square 12 is further provided between the side formwork 11 and the clamping member 101;

[0050] S4. Install the screw 902 on the clamping member 101 and adjust the height of the screw 902;

[0051] Specifically, first install the gasket 901 on the clamping member 101 so that the hole of the gasket 901 and the long hole of the clamping member 101 form a through hole. Pass both ends of the screw rod 902 through the through hole, and install the fastener 903 on the end of the screw rod 902. According to the height of the beam 10, determine the distance between the screw rod 902 and the top template of the beam 10, and fix the screw rod 902 at the corresponding height of the long hole.

[0052] In a preferred embodiment, the height of the beam 10 is relatively high, and multiple screws 902 can be provided at the elongated holes to better fix the side formwork 11 .

[0053] S5. Tighten the fastener 903 to make the clamping member 101 clamp the side template 11.

[0054] After the height of the screw rod 902 is adjusted, the fastener 903 is tightened. At this time, the fastener 903 presses against the clamping member 101 inward. Under the action of the thrust, the clamping member 101 drives the movable member 102 to move toward the partition 7 until the clamping member 101 clamps the side template 11.

[0055] In a specific embodiment, the beam 10 is relatively long, and a plurality of beam template fixing fixtures can be evenly spaced along the length of the beam 10 to securely fix the side templates 11 to both sides of the beam 10 ;

[0056] In other embodiments, according to the different structural configurations of the beam 10 to be constructed, the beam formwork fixing fixture in the present application can also be arranged below the bottom formwork of the beam 10 to fix the two side formworks 11 of the beam 10; it can also be arranged on one side of the beam 10 to fix the upper formwork and lower formwork of the beam 10.

[0057] The beam formwork fixing fixture of the utility model has high structural stability and can be applied to the reinforcement of beam formworks of different heights and widths. The formwork reinforcement and removal operations are simple, which improves construction efficiency; the reinforcement quality is easy to control, which is conducive to forming a good appearance quality.
