Description
Technical Field
The utility model relates to a construction equipment field especially relates to a stake combination formula hoist.
Background
In recent years, the assembled bridge is established as the construction of the special traffic industry of China, and the related policies of China and places frequently come out to encourage the development of the assembled bridge, so as to promote the progress of China from the large bridge country to the strong bridge country. The method takes the rapid development of the assembled bridge as a trigger, and some new materials, new processes and new technologies are continuously innovated and broken through, so as to reach or even exceed the international advanced level. If the new process of 'pile-column integration' is provided, the full prefabrication installation of the bridge lower structure is realized. The pile-column integration means that the pile foundation is firstly implanted into the pipe pile after the hole is formed, and then the pile foundation is connected with the pier column, and the pile-column integration method has the advantages that a bearing platform is omitted, the earth excavation amount is reduced, the construction period is shortened, and further the construction cost is reduced. However, as the assembled bridge is enlarged and complicated, the diameters of the tubular pile and the pier stud are increased, and the length and the weight of the tubular pile and the pier stud after connection are longer and heavier, which provides a greater challenge for a lifting appliance directly bearing the weight of the pile stud.
Traditional hoist mainly has: the method has the advantages that firstly, the lifting lugs are embedded at the end parts of the pile columns when the pile columns are prefabricated and are used as a lifting appliance when the pile columns are lifted, the method is simple in structure and convenient to operate, but for projects needing pile splicing, the lifting lugs need to be cut off, construction procedures are increased, the smoothness of end heads is difficult to guarantee, and pile splicing is not facilitated; the hoop is characterized in that the hoop is fastened and connected between two different materials and mainly comprises an annular hoop plate, a stiffening plate, a bolt and an outward-extending wing plate, two holes are reserved on the wing plate and used for installing steel wire lifting ropes, when the hoop is installed, a rubber pad with the width slightly larger than that of the hoop plate is installed between the hoop and a pile column, the purpose is to increase the fastening effect between the hoop and the pile column and prevent the hoop and the pile column from sliding relatively, the method is more complicated than a pre-embedded lifting lug, the bearable weight is limited, the method is suitable for hoisting and installing the pile column with common weight, when the weight of the pile column is larger, the hoop slides, the wing plate bends, and the method is not applicable any more; thirdly, the hoop and the steel bar are based on the sliding phenomenon of a single hoop, engineers propose that the combination mode of the hoop and the steel bar is adopted to lift and install the pile, namely, the pile is perforated at the upper edge of the hoop and the steel bar is inserted, the method can not only prevent the hoop from sliding through the steel bar, but also can bear partial pulling force, thereby greatly improving the lifting capacity, but also has some defects, for example, the hoop and the steel bar can not be tightly attached when being installed, so that the hoop and the steel bar are not simultaneously stressed when the pile is lifted, but the hoop bears all the pulling force firstly, the steel bar begins to bear the pulling force when the hoop slides and is attached with the steel bar, the condition has great construction risk, once the hoop slides due to the great pulling force, the hoop can generate great inertia force, and the inertia force suddenly impacts the steel bar as a second stress, the concrete of light person's trompil department is crushed, and heavy person will make the crane lose balance and turn on one's side, and in addition, the installation of staple bolt is more loaded down with trivial details, is difficult to accurate location. Therefore, in order to ensure the safety and the construction convenience when the large-tonnage pile is lifted, the existing pile lifting appliance needs to be optimized and innovated.
