Abstract
The utility model relates to a device for lifting inclined steel columns. The device comprises an inclined steel column, and is characterized in that the upper end of the inclined steel column is provided with two lifting lugs which are arranged symmetrically; another two lifting lugs are arranged on a symmetric point regarding the gravity center as a center on the lower end of the inclined steel column; the two lifting lugs at the upper end are respectively fixedly connected by two ends of a lifting rope; the two lifting lugs at the lower end are respectively fixedly connected by two ends of another lifting rope; a lifting hook is positioned above the gravity center line of the inclined steel column; and two lifting ropes are respectively hooked on the lifting hook. The device for lifting inclined steel columns related by the utility model has the advantages that by using the lifting technology, the preparing working in earlier stage is relatively simple; the gravity center is also convenient to be find out in modeling; the lifting lugs are processed simply; compared with the prior manner that one section of steel is lifted, the lifting time in site construction is saved; potential safety hazards in construction are reduced; and precision of mounting components in place is improved.
Description
Technical field
The utility model relates to a kind of device that lifts the inclination steel column.
Background technology
Steel construction originally generally adopts the vertical bar shaped steel structure to build, and it also is to adopt the method for multistage splicing to carry out that crooked place is arranged, but dangerous in aloft work; And efficient is low, and at present along with expanding economy, increasing building with various characteristics emerges in an endless stream; Steel structure in these buildings has the different formed steel construction of many bendings; In order to improve operating efficiency, be employed in factory with regard to the big steel hook spare of Direct Production, therefore must have many abnormally-structured steel hook spares; Mainly be that they self structure has inclination; Will run into a lot of problems when therefore lifting in the building site, when lifting inclination steel column, what adopt usually is following two kinds of methods now:
1), vertical lifting, when treating that steel column puts in place, adjust its angle of inclination again, adopt this hanging method, dead work is simple relatively when lifting, but when member puts in place adjustment correction work relative complex, and there is potential safety hazard greatly in the high-altitude adjustment.
2), the configuration chain block is very heavy, when lifting through manual operation cucurbit adjustment member attitude, though lifting component convenience in place, during lifting working phase to numerous and diverse, not only time-consuming but also require great effort.
Because present inclination steel structure is many, therefore demand carrying out technological improvement urgently, the work efficiency when lifting in the building site to improve the inclination steel structure.
Summary of the invention
The purpose of the utility model is to solve the vertical lifting of lifting inclination steel column employing and the very heavy existing the problems referred to above of configuration chain block in the prior art, and a kind of device that lifts the inclination steel column is provided.A kind of device that lifts the inclination steel column of the utility model design; Comprise the inclination steel column; It is characterized in that: two hangers are laid in the upper end at the inclination steel column, and two hangers are two other hangers of symmetric points laying at center for being symmetrical set with the center of gravity in the lower end of inclination steel column; Two hangers of upper end are by the two ends difference captive joint of a lifting rope; Two hangers of lower end have the two ends difference captive joint of another root lifting rope, and suspension hook is positioned at the top of the center of gravity line of inclination steel column, and two lifting ropes are hooked on the suspension hook respectively.The utility model has the advantages that and adopt this kind hoisting technology; Preliminary preparation is simple relatively; Center of gravity is also conveniently found out when modeling, and hanger processing is simple, and site operation is saved 1/3 the lifting time nearly than lift a joint steel in the past; And reduced the potential safety hazard that construction brings, improved the accuracy rate that member is in place.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model, and Fig. 2 is the left view of Fig. 1.
The specific embodiment
Comprise inclination steel column 1 among the figure; It is characterized in that: laying 2, two hangers of two hangers in the upper end of inclination steel column for being symmetrical set, is two other hangers 3 of symmetric points laying at center with center of gravity 7 in the lower end of inclination steel column; Two hangers of upper end are by the two ends difference captive joint of a lifting rope 4; Two hangers of lower end have the two ends difference captive joint of another root lifting rope 5, and suspension hook 6 is positioned at the top of the center of gravity line of inclination steel column, and two lifting ropes are hooked on the suspension hook respectively.
As shown in the figure, the upper end hanger adopts original steel column to connect hanger, and the lower end hanger is symmetrical set according to center of gravity, adopts 4 liftings; When hanger was provided with, at first existing lifting rope 4,5 length of considered also should avoid lifting rope and steel column bracket to collide; Lifting rope adopts single one to do two, left and right sides break-through, and the attitude when lifting rope length is utilized the member installation in position is calculated; Article two, lifting rope just in time intersects on center of gravity line, and member Hui Zhi slowly during lifting is because of the lifting rope limitation of length; When suspension hook position and center of gravity arrived a straight line, member arrived state of equilibrium, and this moment, the member attitude was member installation in position attitude.
Lifting part utilizes the computer software modeling to confirm the center of gravity on its inner space when in-depth; On two planes of symmetry of center of gravity, select two groups of four hangers then, two groups of hangers are symmetrical in twos along center of gravity up and down, and one of lifting rope with two different length is fixed on the hanger simultaneously; The other end is fixed on the symmetrical hanger; And then another root lifting rope is fixing equally, be hooked on the lifting rope with suspension hook at last, lifting rope adopts regular length.Suspension hook is sling lifting rope, and member is Hui Zhi slowly, and when suspension hook was positioned at a straight line of center of gravity, this moment, lifting rope just in time was parked in place, 1/2nd force automatically, can guarantee that its attitude steadily slings the inclination steel column.
In large scale special-shaped structural steel Structural Engineering now, all can adopt this kind technology to carry out lifting component usually, and can it be extended to the lifting of other abnormity components, lift through being symmetrical set hanger according to center of gravity and disposing very heavy method.This kind technology will design, construct and process and be closely connected, and satisfy the site operation demand, save the construction period, improve operating efficiency greatly.
