Description

Technical Field

[0001] This utility model relates to the technical field of building formwork installation equipment, specifically a building formwork installation device. Background Technology

[0002] In building construction, the installation and fixing of formwork is a crucial process to ensure the quality of concrete structure formation. Traditional formwork installation methods mainly rely on manual operation, using conventional tools such as wrenches and nuts for fixing, which has many drawbacks.

[0003] While some auxiliary tools exist for template installation, their functions are relatively limited, making it difficult to quickly lock bolts and nuts in place. Some tools are incompatible with different bolt and nut specifications, restricting their versatility. Furthermore, many tools lack effective fixing and limiting functions, making them prone to displacement or loosening during operation, thus affecting the installation results.

[0004] Therefore, there is a need for a device that can improve the efficiency of building formwork installation, has strong compatibility, and is easy to operate, so as to achieve rapid locking of bolts and nuts and improve the overall quality and safety of formwork installation. Utility Model Content

An elastic ball structure is provided between the rectangular hole 37 and the upper sleeve 19, and between the rectangular hole 37 and the lower sleeve 18. The upper sleeve 19 is snapped and fixed to the rectangular hole 37 by the elastic ball structure, and the lower sleeve 18 is snapped and fixed to the rectangular hole 37.

[0033] Advantageously, the elastic ball structure includes spherical grooves 38 disposed in the end walls of both sides of the rectangular hole 37, two sliding grooves 36 disposed in the upper sleeve 19 and the lower sleeve 18, a ball-head telescopic rod 34 slidably disposed in the sliding groove 36, and a spring 35 elastically disposed between the ball-head telescopic rod 34 and the sliding groove 36.

[0034] Advantageously, the outer surfaces of the upper sleeve 19 and the lower sleeve 18 are fixedly provided with limiting plates 41, which can be directly sleeved on the outer surface of the upper sleeve 19 and fixed by fasteners or welding. The limiting plate 41 is provided with an arc-shaped through hole 42. After the ball-head telescopic rod 34 abuts against the arc-shaped through hole 42, the ball-head telescopic rod 34 protrudes out of the limiting plate 41. After the limiting plate 41 is provided, the overall dimensions of the limiting plate 41 and the upper sleeve 19, as well as the limiting plate 41 and the lower sleeve 18, need to be able to be inserted into the rectangular hole 37.

[0035] When using the device, the personnel set the bolts 33 in the upper and lower splicing templates. They can first rotate the nut 31 on the bolts 33 to restrict the rotation of the bolts 33. Then, they can turn the nut 31 to make it threadedly engage with the bolts 33, so that the bolts 33 can lock and fix the upper and lower splicing templates.

[0036] Alternatively, the bolt 33 can be placed in the template first, and then the nut 31 can be placed in the lower sleeve 18. Then, the nut 31 and the bolt 33 can be rotated and locked together using a tool.

[0037] After the bolt 33 is placed in the template, the upper sleeve 19 is fitted onto the nut part of the bolt 33, and the upper sleeve 19 is magnetically fixed to the template and the bolt 33 by magnetic attraction. Then, the operator moves the hand drill 11 upwards, and the guide rod 24 and the sliding rod 22 slide relative to each other, so that the nut 31 in the lower sleeve 18 abuts against the threaded part of the bolt 33.

[0038] By pressing the switch of the electric drill 11, the operator drives the self-locking chuck 12 and the drive shaft 14 to rotate. After the drive shaft 14 rotates, it drives the driving bevel gear 15 and the driven bevel gear 16 to rotate. Since the lower rotating cylinder 17 is coaxially connected to the driven bevel gear 16, it can drive the lower rotating cylinder 17, the lower sleeve 18 and the nut 31 to rotate, so that the nut 31 and the bolt 33 are gradually tightened. In this way, the nut 31 and the bolt 33 can be fixedly connected to the template.

[0039] Then, the operator moves the electric drill 11 downwards to disengage the lower sleeve 18 from the nut 31. Then, the operator pulls the sliding rod 22, the upper rotating cylinder 21, and the upper sleeve 19 upwards to disengage the upper sleeve 19 from the bolt 33 and the template.

[0040] When replacing the lower sleeve 18 and the upper sleeve 19, simply pull the lower sleeve 18 out of the lower rotating cylinder 17 and the upper sleeve 19 out of the upper rotating cylinder 21. At this time, the ball head telescopic rod 34 retracts into the slide groove 36 to compress the spring 35, and the ball head telescopic rod 34 disengages from the abutment and fixation of the spherical groove 38, so that the upper sleeve 19 and the lower sleeve 18 can be pulled out. Then, the lower sleeve 18 and the upper sleeve 19 of other specifications can be reinstalled.

[0041] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
