The not enough to prior art, the utility model provides a big eccentric atress hoisting frame device of support frame is done concurrently, with hoisting frame and support frame rational combination, the big eccentric bending moment that the promotion support body bore when balanced promotion construction guarantees to promote the stability of support body, and stable in structure, safety has reduced simultaneously and has taken in the place, and it is convenient to ann tear open, has improved the efficiency of construction.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a do big eccentric atress hoisting frame device of support frame concurrently, includes the support frame section, the top fixedly connected with hoisting frame section of support frame section, the hoisting frame section is including promoting the support body, the top that promotes the support body is provided with the hoisting beam of encorbelmenting, the lower part of the hoisting beam of encorbelmenting with it is provided with the fore-stock to promote between the support body, promote support body top fixedly connected with back of the body pull rod, the back of the body pull rod is located the relative one side of the end of encorbelmenting of the hoisting beam of encorbelmenting.
The lifting frame section is arranged on the support frame section and is fixedly connected with the support frame section; the top of the hoisting frame is provided with an overhanging hoisting beam, and meanwhile, in order to ensure the rigidity and the strength of the overhanging hoisting beam when stressed, the lower part of the overhanging hoisting beam is provided with a front support rod which is fixedly connected with the support frame body and is used for transmitting hoisting load; in order to balance the large eccentric bending moment borne by the lifting frame body during lifting construction, a back pull rod is arranged between the top of the lifting frame body and the mounted structure, and load is transmitted to the mounted structure. When the hoisting frame section is installed, the installation of the upper structure of the support frame section is required to be completed. Firstly, a hoisting frame body is installed, then a top overhanging hoisting beam and a front support rod are installed, and finally a back pull rod is installed.
Further, the lifting frame body is connected with a temporary fixing rod, and the lifting frame body is fixedly connected with the installed structure. Partial web members of the lifting frame body cannot be installed due to the influence of the installed structure, and temporary fixing rods are suitable to be adopted to connect and fix the lifting frame body upright rod and the installed structure for ensuring the stability of the lifting frame body.
Furthermore, a steel strand hole is reserved in the overhanging lifting beam and is used for installation work of the lifting device.
Furthermore, the lifting frame section is positioned on the support frame section, the lifting frame section and the support frame section are fixedly connected, and the vertical positions of the vertical rods are kept consistent.
To sum up, the utility model discloses with hoisting frame and support frame rational combination, the stability of hoisting the support body is guaranteed to the big eccentric bending moment that the hoisting support body bore when balanced promotion construction, and stable in structure, safety have reduced simultaneously to occuping in place, and ann tears open conveniently, has improved the efficiency of construction. The utility model discloses still have following beneficial effect:
(1) the structure is simple, and the installation and the disassembly are convenient;
(2) the application range is wide, and the method can be used for construction of different steel structure engineering lifting methods;
(3) the structure arrangement is ingenious, the force transmission is direct, and the stress performance is good;
(4) the economical efficiency is good, the measure amount can be effectively reduced, the construction period is shortened, and the work efficiency is improved.
