Integral in-situ lifting sling for steel structure corridor

ActiveCN224185787Uwill not affect operationeffectively fixedLifting framesMechanical engineeringVeranda
The utility model relates to the technical field of building steel structure installation, and discloses a steel structure corridor integral in-situ lifting sling, which comprises a sling main body, one end of the sling main body is fixedly connected with the outer side wall of a steel structure corridor lower chord member, and a temporary reinforcing rod is arranged above the steel structure corridor lower chord member corresponding to the joint. The lower end of the temporary reinforcing rod is fixedly connected with the upper surface of the steel structure corridor lower chord member, and the upper end of the temporary reinforcing rod is fixedly connected with the corresponding steel structure corridor diagonal web member on the upper side; a round hole for a steel strand in the hydraulic lifter to penetrate through from top to bottom is formed in one end, far away from the steel structure corridor, of the lifting appliance main body, and a ground anchor capable of clamping and fixing the end of the steel strand is further mounted on the lifting appliance main body below the round hole; the lifting appliance main body needs to extend out of the projection of the steel structure corridor, and the lifting appliance main body cannot be shielded by an upper chord of the steel structure corridor. According to the utility model, through the design of the lower chord lifting appliance, conditions are created for integrally lifting the steel structure corridor in a narrow space.

Method for installing large-scale fluid lifting skid

PendingCN122211952Aachieve installationSolve the problem of unable to installLoad-engaging elementsCranes
The application provides a large-scale fluid lifting sliding installation method, which comprises the following steps: S1. Dividing a large-scale fluid into n fluid segments along the length direction of the large-scale fluid, n is greater than or equal to 5, and setting a lifting bracket; S2. Setting a sliding device in a channel below an installation position, and setting a lifting device on the sliding device; S3. Assembling a first part of the fluid segments on the sliding device, the first part comprises the fluid segments provided with the lifting bracket; connecting the lifting device with the lifting bracket on the first part, and lifting the first part to a set height; S4. Assembling a second part of the fluid segments on the sliding device, and sliding the second part to below the first part; lowering the first part to abut with the second part, and forming the large-scale fluid; S5. Reconnecting the lifting device with the lifting bracket on the abutted large-scale fluid, and sliding the large-scale fluid to the installation position through the sliding device. The application can realize the installation of the large-scale fluid in a narrow space.
