Adjustable frame for sliding of steel structure truss

The invention discloses an adjustable frame for sliding of a steel structure truss. The adjustable frame for sliding of the steel structure truss is used in the technical field of building construction and comprises a frame base. The frame base is formed by sequentially welding H-shaped steel I, H-shaped steel II with the variable section and H-shaped steel III, and four sets of stripe-shaped bolt grooves are formed in the plane of the frame base. The middle two sets of stripe-shaped bolt grooves are each connected with a frame strut. The two sets of stripe-shaped bolt grooves at the two ends are each connected with a frame inclined strut. The other ends of the frame inclined struts are fixed to the frame struts. Two sets of rolling sliding devices are arranged on the lower surface of frame base. According to the adjustable frame, a stable triangular structure is formed by the frame struts, the frame inclined struts and the frame base, the steel structure truss can be clamped and fixed and can be prevented from overturning in the sliding process, the distance between the frame struts can be adjusted to adapt to trusses with different section widths, and the adjustable frame has the advantages of being adjustable and capable of being used repeatedly, and is convenient and fast to move, low in cost and high in safety.
