[0002] In the modern construction industry, steel bar processing technology is becoming more standardized. At present, centralized steel bar processing and distribution are mostly used to achieve fast and efficient production. In the overall hoisting process, triangular truss hangers are often used to ensure that the steel bar skeleton does not deform during the hoisting process.

[0003] Since the design height of the steel bar processing shed is generally 10 meters, the cost will increase significantly if it exceeds 10 meters. At this time, the triangular truss is too high and the gantry crane cannot lift the steel bar skeleton from the frame due to insufficient lifting height. This will affect the construction efficiency and may also delay the project progress, increase construction costs, and bring many inconveniences and potential risks to the entire project.

[0025] like Figure 2 , 3 As shown, a plurality of adjustment holes 12 with the same spacing are respectively provided on the upper part of the corresponding flower rack 2 and the crossbeam 3 .

[0026] like Figure 3 As shown, the locking assembly includes an upper top plate 13 and a lower top plate 14 with the same cross-section. The upper top plate 13 and the lower top plate 14 are provided with matching through holes and tensioning bolts 15 are inserted therein. Both ends of the tensioning bolts 15 pass through the upper top plate 13 and the lower top plate 14 respectively and locking nuts 16 are provided at the ends.

[0027] like Figure 3 As shown, the through holes on the vertical surfaces of the upper top plate 13 and the lower top plate 14 match the adjustment holes 12 on the crossbeam 3 .

[0028] like Figure 4 As shown, the lifting assembly includes a frame-shaped support block 17 supported on the upper part of the lower cross bar 6, a slider 18 is inserted into the lower part of the frame-shaped support block 17, a lifting ear 19 is integrally provided at the lower part of the slider 18, a locking screw 20 is penetrated through the frame-shaped support block 17, a threaded hole is opened in the middle of the slider 18, and the locking screw 20 extends downward and is threadedly connected to the threaded hole.

[0029] like Figure 4 As shown, the slider 18 can slide in the second slide groove 11, and the width of the lifting ear 19 is 30-50 mm greater than the width of the second slide groove 11.

[0030] like Figure 4As shown, the combined cross-section of the frame-shaped support block 17, the slider 18 and the lifting lug 19 is an I-shaped cross-section.

[0031] The implementation principle of a steel cage hoisting truss in the embodiment of the present application is:

[0032] Before hoisting, adjust the width of the hoisting truss. When adjusting, first connect and fix any truss main beam 1 with the adjustment hole 12 on one side of the flower rack 2 by bolts, then move another truss main beam 1 to the corresponding width, and then connect and fix it with the adjustment hole 12 on the other side of the flower rack 2 by bolts. After adjusting the width of the hoisting truss, determine the width between the crossbeams 3 and connect them with the corresponding truss main beam 1;

[0033] When connecting the crossbeam 3, first place the crossbeam 3 to the specified position (determined according to the on-site conditions, the width between the crossbeams 3 corresponds to the position of the lifting point), and then place the corresponding upper top plate 13 on the upper part of the crossbeam 3, and place the lower top plate 14 on the lower part of the corresponding upper crossbar 5. After placement, it is also necessary to ensure that the through holes on the vertical surfaces of the upper top plate 13 and the lower top plate 14 correspond to the adjustment holes 12 on the crossbeam 3, and at the same time ensure that the through holes on the prepared horizontal surfaces of the upper top plate 13 and the lower top plate 14 are directly above and directly below the first slide groove 10. When all conditions are met, connect and fix. When connecting and fixing, pass the tension bolts 15 through the upper top plate 13 and the lower top plate 14, and tighten them with the locking nuts 16 to ensure that the lifting ring 4 does not deviate by itself.

[0034] After the crossbeam 3 is connected, the lifting rope is hung on the lifting ring 4. After hanging, the lifting truss is lifted to adjust and fix the position of each lifting ear 19 (the position is adjusted according to the steel frame hoisted on site). During adjustment, the locking screw 20 is turned to make the slider 18 move outward from the inside of the frame support block 17. At the same time, a certain gap will appear between the lifting ear 19 and the lower part of the lower cross bar 6. When the gap appears, the frame support block 17, the slider 18 and the lifting ear 19 are moved along the second slide groove 11 at the same time, so that the frame support block 17, the slider 18 and the lifting ear 19 are located in the specified position (adjusted according to the on-site conditions). After reaching the specified position, the locking screw 20 is turned in the opposite direction, and the slider 18 moves up. When the slider 18 moves up, it will drive the lifting ear 19 to move up. After moving up to a certain distance, the lifting ear 19 will clamp the lower cross bar 6 tightly with the frame support block 17 to prevent the lifting ear 19 from moving, affecting the lifting process;

[0035] After all the lifting eyes 19 are fixed, the lifting eyes 19 are connected and fixed to the steel cage by slings. After the connection, the steel cage is lifted to the designated position by a crane. The whole process can not only carry out lifting operations in a limited space, but also greatly improve the work efficiency in construction, speed up the progress of the project, reduce the construction cost, bring convenience to the whole project, and avoid potential risks.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
