Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a jack fixing device for tensioning prestressed frame beams in building construction. Background Technology

[0002] In the field of building construction, prestressed frame beam tensioning technology is a crucial process. Specifically, it involves tensioning the prestressing tendons within the frame beam before it bears any external loads, thus pre-stressing the beam. When the frame beam is put into use and subjected to external loads such as floor loads and wind loads, the tensile stress generated by these loads within the beam will initially offset some of the pre-applied compressive stress. This pre-stressing method significantly improves the load-bearing capacity of the frame beam, effectively reduces cracking under normal use conditions, and greatly enhances the beam's stiffness, resulting in less deformation under load.

[0003] In the construction of prestressed frame beams in building construction, the stable fixing of tensioning jacks is crucial. The following problems exist: First, the jacks used for tensioning operations are usually quite heavy, often requiring multiple workers to work together to lift and install them. This not only wastes significant human resources but also prolongs the entire installation process, severely impacting construction efficiency. Second, tensioning jacks and related equipment, such as tool anchors, lack fixed and reasonable storage locations on the construction site. Tool anchors and their associated operating equipment, in particular, are haphazardly placed, creating a chaotic and disorganized scene. Utility Model Content

The top crossbeam 13 is welded and fixed to the top of the moving frame 1. The horizontal beams are vertically connected to the frame 12. There are two horizontal beams, which are arranged in parallel. One end of the two horizontal beams is fixedly installed on the frame 12, and the other end of the two horizontal beams is fixedly connected by a crossbar. A hoisting mechanism 14 is fixedly installed on the horizontal beams. The hoisting mechanism 14 can be a winch device composed of a drum, wire rope 141, motor, brake, etc. The motor is installed as a power source at a suitable position on the top crossbeam 13 and drives the drum to rotate through a transmission device. A steel wire rope 141 is wound on a drum.

[0031] Lifting and Height Adjustment of Jack 3: The lifting mechanism 14 is activated, and the lifting mechanism 14 drives the moving support 2 upward via the wire rope 141, raising the jack 3 placed on the sliding mounting body 21 to a height matching the tensioning position of the prestressed frame beam. During the lifting process, the height of the jack 3 can be precisely adjusted according to actual needs by controlling the running speed and stopping position of the lifting mechanism 14.

[0032] Horizontal position adjustment of jack 3: After jack 3 reaches the appropriate height, the horizontal drive mechanism 23 is activated. The horizontal drive mechanism 23 drives the sliding mounting body 21 to move horizontally on the moving support 2, thereby driving jack 3 to move along the moving support 2, so that the position of jack 3 is accurately aligned with the prestressing tendons of the prestressed frame beam, ensuring that the tensioning operation can be carried out smoothly.

[0033] Tensioning and Device Reset: After adjusting the position of jack 3, connect jack 3 to the prestressing tendons and perform the tensioning operation. After the tensioning operation is completed, the jack 3 is moved from the placement opening back into the placement box 24 by the reverse movement of the hoisting mechanism 14 and the horizontal drive mechanism 23, facilitating subsequent operations or equipment storage.
