Embodiment
[0020] When used, such as figure 2 Shown, a cross-section H-shaped steel 13 of a certain engineering structural steel beam, at first the base plate 1 of the present invention is placed on the upper side of the lower flange plate of the H-shaped steel 13, the supporting nut is rotated, and the height of the sleeve is adjusted so that the The top plate 6 is closely attached to the underside of the upper flange of the H-shaped steel 13, and the device is embedded in the H-shaped steel 13 through the above adjustment; 9 Lift the supporting plate 8 to adjust the height of the C-shaped steel keel 14. After the height reaches the elevation requirement, turn the fastener 12 to fix the lower part of the C-shaped steel keel 14 so that it is tightly fixed on the supporting plate 8, and at the same time adjust the clamp of the stabilizer 4 The height makes the L-shaped draw hook 5 close to the upper part of the C-shaped steel keel 14, and rotate the draw hook 5 to make it close to the ed...

The invention relates to an adjustable build-in lifting supporting device for a steel structure building. The device comprises a placement-type lifting support, the support comprises a long screw anda short screw, the bottoms of the two screws are flush with each other and parallel with each other, and a baseplate is fixedly connected to the bottoms of the two screws; a supporting plate is arranged between the two screws, the height of the supporting plate can be adjusted in the up-down direction, and a liftable top supporting part is arranged on the upper portion of the long screw; a top plate is fixedly connected to the upper end of the top supporting part, a stabilization part is arranged on the top supporting part, and a clamping groove for containing a C-shaped steel keel is formed between the stabilization part and the supporting plate. The device is suitable for a formwork supporting system with H-shaped steel, groove steel and other components as composite floor slabs or cast-in-situ reinforced concrete floor slabs of buildings with structure steel beams, the formwork supporting technology is simple, easy to operate and convenient to use, the working period is shortened, and resource allocation of manpower and mechanical equipment is reduced.
Description
technical field [0001] The invention belongs to the field of construction, and relates to a floor formwork and a support device for a laminated slab bottom, in particular to a cast-in-place construction for buildings such as steel structure residences and industrial plants with H-shaped steel, channel steel, I-beam, and angle steel as structural steel beams. It is an adjustable embedded lifting support device used in the erection of reinforced concrete floor (laminated slab) formwork. Background technique [0002] Today, when the country vigorously promotes the development of green buildings, steel structure buildings have become the driving force for construction due to their advantages of light weight, high strength, fast construction speed, and good seismic performance. A new force in industrialization, informatization and industrialization. Therefore, it is urgent to study the formwork support technology suitable for steel structure buildings. At present, the tradition...
