Description
Technical field
The utility model relates to the lifting field, refers to specifically that a kind of fixed type tower crane body of the tower height exceeds standard to use bracing means.
Background technology
In the installation process of some large-scale refinery ethylene cracker engineering cracking furnace, consider that cracking furnace steel structure, furnace body and matching construction installation workload are big, construction operation point is high, long construction period, and the construction operation face is concentrated, and therefore uses the tower capable lifting operation of lifting up into usually.In the operation zone, there are many tower cranes to work simultaneously, and when the operating area area is restricted, distance between the tower crane can not guarantee tower crane lifting operating mode and use the safety distance that need reach under the situation, need do certain tower crane body of the tower height and increase a standard knot and adjust.The height of one standard knot is 3.75 meters.Tower crane after increasing is above standard behind the installation requirement, according to the lifting requirements of tower crane, needs to carry out attaching frame to body of the tower within a certain height and reinforces, and plays the effect of firm body of the tower.But,, attaching frame need be reinforced on the cracking furnace steel structure if attaching frame is set because condition is placed restrictions in the operating area.Carry out pulling-rod frame admittedly and on the cracking furnace steel structure, add attaching frame, must check and approve through the calculating of cracking furnace structural steelwork design side, very trouble.Also having a kind of measure is exactly a joint that increases all to be mixed earth and former basis with reinforcing bar fuse and carry out consolidation process, but this way cost height, time duration are long, and the dismounting work in later stage has been increased certain difficulty.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of consolidation effect is good and construction cost is low fixed type tower crane body of the tower height to exceed standard to use bracing means.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this fixed type tower crane body of the tower height exceeds standard and uses bracing means, it is characterized in that comprising many strut bars, each strut bar tilts to be welded on the tower crane body of the tower to be reinforced, and each strut bar is identical with ground-surface angle.
Described strut bar has eight, and the upper end of per two strut bars is welded on the hoop, on the described tower crane body of the tower of described hoop captive joint.
Also be provided with pipe link between the adjacent described hoop, and four planes, pipe link place and described tower crane body of the tower are perpendicular; The lower end of the described strut bar of adjacent each is equipped with the connection gusset, and each connects the plane parallel at plane and each pipe link place at gusset place.
The lower end of each described strut bar is welded on respectively accordingly on the connecting panel, and each connecting panel connects cooresponding supporting baseplate respectively.
Angle between described strut bar and the ground is 45～60 °, and the distance between described pipe link and the ground is 3～4 meters.)
Compared with prior art, that fixed type tower crane body of the tower height provided by the utility model exceeds standard is simple and convenient with bracing means construction, draw materials easily, safe in utilization, and the dismounting of construction after finishing also is easy to.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment;
Fig. 2 is the perspective view of embracing basket among the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fixed type tower crane body of the tower height in the present embodiment exceeds standard and is applied on the installation tower crane body of the tower of cracking furnace in certain large-scale ethylene cracker engineering with bracing means.Because cracking furnace steel structure, furnace body and matching construction installation workload are big, construction operation point is high, long construction period, and the construction operation face is concentrated, and therefore adopts the fixed type tower crane to carry out lifting operation.In this project installation region, 6 cracking bases of word order are arranged, tower crane is installed in the east side on cracking basis, adopts TC7035 type fixed type tower crane, to solve level and the vertical transport problem that the cracking furnace parts are installed.It is 64 meters height, 55 meters brachiums that operating mode is installed, and the lifting load is between 5.38～10.66 tons.Because two highly close tower cranes are also arranged in construction area in addition, according to the lifting operating mode and use the safety distance that need reach standard-required, this fixed type tower crane body of the tower height must be increased the height of 3.75 meter one joint, just can reach the safety requirements that three tower cranes use simultaneously.And the fixed type tower crane body of the tower after increasing needs to reinforce in the certain height scope, to play the effect of firm body of the tower.
As shown in Figure 1, this fixed type tower crane body of the tower height exceeds standard and comprises with bracing means:
Four pipe links 3, the two ends of each pipe link 3 are welded on respectively on two adjacent hoops 2; Pipe link 3 welding back forms the rectangle similar to the cross section of described tower crane body of the tower 1, and the plane at four pipe link 3 places and tower crane body of the tower 1 are perpendicular;
Eight strut bars 4, the upper end of per two strut bars 4 are welded on two sides of a hoop 2 after all connecting by No. 16 channel-section steels, and the lower end of each strut bar 4 is welded on respectively on its cooresponding connecting panel 5; Each strut bar 4 is 56 ° with ground-surface angle in the present embodiment, and connecting panel 5 welds mutually with supporting baseplate 7.The angle of inclination of strut bar, distributing position and radical need be determined according to the force analysis of tower crane.Strut bar 4 in the present embodiment adopts the pipe of φ 159 * 8 above specifications to manufacture.
Eight pipe links 6, each pipe link 6 welds mutually with supporting baseplate 7, and the position of each supporting baseplate 7 is determined according to the height of hoop 2 and the angle of inclination of strut bar 4.Pipe link 6 is provided with on the ground, and eight pipe links 6 are interconnected to constitute octagon, and the plane at this octagon place and tower crane body of the tower 1 are perpendicular.Supporting baseplate in the present embodiment adopts 300 * 200 * 20 steel plate, and the reinforcing bar of employing φ 20 * 300 is fixed on the mixed earth basis of former cement steel with the way of chemically-planted steel bar.
That this fixed type tower crane body of the tower height exceeds standard is simple and convenient with bracing means construction, it is convenient, safe in utilization to draw materials, and is particularly suitable for on-the-spot emergent the use.
