Abstract

The invention relates to a hydraulic displacement control slip unloading device and a method for manufacturing and unloading a member. The unloading device comprises a rectangular supporting base (1), two limiting hydraulic rods (2), two baffles (3), and right-angled triangular plates (4), wherein a set of parallel sliding grooves (1a) is formed in the top face of the rectangular supporting base (1), the limiting hydraulic rods (2) are symmetrically installed at the two sides of the supporting base and parallel to the sliding grooves, the baffles (3) are symmetrically installed at the other two sides of the supporting base and are in parallel and capable of sliding along the sliding grooves, and the right-angled triangular plates (4) are installed on the supporting base and located between the two baffles and can slide along the sliding grooves. The two ends of each baffle are installed on the limiting hydraulic rods in a sleeving mode respectively, convex guide rails (1b) are formed between the sliding grooves, the number of the right-angled triangular plates is at least three, two right-angled triangular plates are symmetrically installed and at least spaced by one sliding groove, and the two right-angled edges are attached to the supporting base and the baffle at one side; the third right-angled triangular plate is located between the two right-angled triangular plates and installed oppositely, and the two right-angled edges are attached to the supporting base and the baffle at the other side. The unloading device is used for unloading of steel structure engineering and is easy to operate, high in stability and high in control precision.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a tool for unloading construction in the construction process of a steel structure. Background technique [0002] Steel structure engineering, especially the installation of large-span steel grid structures in space, often uses support frames to complete the construction. After the structure is installed, it forms a stable stress system with the support frames. Finally, the support frames need to be removed and the support frames are released. The load borne is transferred to be borne by the structure itself, and this construction step is unloading. At present, the commonly used methods for unloading structural support systems include screw jack unloading method, electronically controlled hydraulic jack unloading method, and sand box unloading method. For engineering projects with more supporting points, more jack equipment needs to be set, which increases the con...
