However, building construction often requires clamping formwork of different specifications. Improper clamping can easily cause cracks in the formwork, affecting the quality of the building project. Therefore, beam clamps need to have both horizontal and vertical adjustable functions.

[0004] Patent document CN207314839U discloses an adjustable beam clamp for holding building beams of different specifications during casting. It includes a pair of triangular frames, a base beam, an adjustable locking mechanism, and a height-adjustable telescopic section. The triangular frames adopt a right-angled triangular truss structure, with symmetrical right-angled columns on the base beam and right-angled columns on the inner side. The bottom formwork of the building beam is set between the right-angled columns, and the triangular frames are fixed to the base beam by the adjustable locking mechanism. The positions of the two right-angled columns can be adjusted to accommodate bottom formwork of different widths. A height-adjustable telescopic section is installed above the right-angled columns to accommodate side formwork of building beams of different heights.

[0005] However, the above-mentioned beam clamps have problems such as complex structure, many small parts, low adjustment and installation efficiency, and inconvenience in disassembly and storage.

The embodiments of this utility model will now be described based on its overall structure.

[0041] like Figures 1 to 4 As shown, this utility model discloses a bidirectional adjustable beam clamp, including a crossbeam 1, a movable clamp 2, a lateral adjustment mechanism 3, and a locking mechanism 4. The crossbeam 1 has a slide rail 11 extending through both ends. The movable clamp 2 includes a support arm 21, a vertical groove 22, and a clamping plate 23. One end of the support arm 21 is connected to the vertical groove 22, and the other end is slidably connected to one end of the slide rail 11. The vertical groove 22 has multiple vertically spaced positions for installing the clamping plate 23 to adjust the extension height of the clamping plate 23. The lateral adjustment mechanism 3 includes a knob 3. 1. Gear 32 and rack 33. The upper end of the knob 31 is located on the upper surface of the crossbeam 1, and the lower end passes through the slide rail 11 and is connected to the gear 32. One end of the rack 33 is connected to the other end of the support arm 21. When the knob 31 is rotated, the support arms 21 at both ends of the slide rail 11 are driven to move inward or outward simultaneously through the meshing gear 32 and rack 33. It has the advantage of simple adjustment structure and can improve adjustment and installation efficiency. The knob 31 is fixedly connected to the crossbeam 1 through the locking mechanism 4, which facilitates the overall disassembly and assembly of the beam clamp.

[0042] Specifically, such as Figures 5 to 8 As shown, the movable chuck 2 also includes a secondary plate 24 and an elastic element 25. The secondary plate 24 is located inside the clamping plate 23 and is connected to the clamping plate 23 via the elastic element 25. (Continue to refer to...) Figure 3 The elastic element 25 includes a sliding column 251 and a first spring 252. The inner side of the clamping plate 23 is provided with a slot 231 that matches the sliding column 251. One end of the first spring 252 is connected to the bottom wall of the slot 231, and the other end is connected to one end of the sliding column 251. The other end of the sliding column 251 is connected to the sub-plate 24. In this embodiment, three sliding columns 251 are spaced apart on the outer side of the sub-plate 24, which can improve the support stability of the sub-plate 24. A rubber sheet can be provided on the inner side of the sub-plate 24 to increase the contact surface and friction with the beam template. By providing the sub-plate 24 and the elastic element 25 on the inner side of the clamping plate 23, the adjustment range of the lateral adjustment mechanism 3 can be enhanced, and lateral clamping failure caused by beam template deformation or tilting can be avoided.

[0043] Specifically, such as Figures 9 to 10 As shown, the locking mechanism 4 includes a cylinder 41, a second spring 42, and a movable engaging part 43. The cylinder 41 is located on the bottom wall of the slide rail 11, and the second spring 42 is sleeved on the cylinder 41. The bottom of the gear 32 has a circular hole 321 that slides through the cylinder 41. The movable engaging part 43 is located on the top of the gear 32. The second spring 42 is in a compressed state. The elastic force generated by the pre-compression of the second spring 42 drives the gear 32 to move upward and is locked by the movable engaging part 43. The gear 32 is driven downward by an external force to release the locking state. The structure is simple and the linkage effect is good. (Continue to refer to...) Figure 10 The movable engagement part 43 includes an upper ratchet ring 431 and a lower ratchet ring 432 that match each other. The upper ratchet ring 431 is located on the top wall of the slide 11, and the lower ratchet ring 432 is located on the top of the gear 32.

[0044] Furthermore, the upper ratchet ring 431 and the lower ratchet ring 432 are configured with a one-way locking structure to restrict the gear 32 from rotating outward in the direction of the support arm 21, while allowing flexible adjustment in the inward translation direction. It is worth noting that initially, the upper ratchet ring 431 and the lower ratchet ring 432 remain engaged under the elastic force of the second spring 42. When an external force drives the knob 31 to rotate clockwise, the lower ratchet ring 432 rotates along the ratchet ramp of the upper ratchet ring 431, causing the support arms 21 at both ends to translate inward simultaneously. When the moving clamp 2 holds the beam template, the support arm 21 is subjected to the reaction force of the elastic element 25, causing the knob 31 to rotate counterclockwise, thus... The lower ratchet ring 432 and the upper ratchet ring 431 abut and lock together. When the external force drives the gear 32 to move downward until the lower ratchet ring 432 and the upper ratchet ring 431 separate, the support arms 21 at both ends move outward simultaneously under the reaction force of the elastic element 25, and drive the knob 31 to rotate counterclockwise. At the same time, the external force assists in rotating the knob 31 counterclockwise, which can quickly release the clamping state of the beam clamp on the beam template and significantly improve the overall disassembly efficiency.

[0045] Continue to refer to Figure 1 and Figure 4 The support arm 21 includes a first groove 211 located on the side away from the rack 33. The other end of the rack 33 passes through the first groove 211, allowing the support arm 21 to have a larger lateral adjustment range. Further, the support arm 21 includes a second groove 212, and the crossbeam 1 includes protrusions 12 that match the second groove 212. The protrusions 12 are respectively located at both ends of the slide rail 11 to limit the outward movement distance of the support arm 21 and prevent the other end of the support arm 21 from disengaging from the end of the slide rail 11. Preferably, the rack 33 includes balls 331, with multiple balls 331 spaced apart on the contact surface between the rack 33 and the slide rail 11. The balls 331 are embedded in the rack 33, reducing friction with the slide rail 11 and making the rotation of the knob 31 easier. In addition, the vertical groove 22 and the clamping plate 23 are respectively provided with multiple vertically spaced through holes 221. The vertical groove 22 and the clamping plate 23 are detachably connected by fastening bolts 222, which facilitates the adjustment of the extension height of the clamping plate 23.

[0046] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
