Abstract
The utility model relates to a kind of steel crane beam installed height mark adjusting device, comprises two jack, also comprises two clamps and supports channel-section steel; On described two clamps, inner side offers grafting gap in the same position at top, and all offers rectangular through-hole in the same position near bottom; Described support channel-section steel two ends are fixed by securing member through after rectangular through-hole, and described jack is arranged on the support channel-section steel between described two clamps.The utility model changes the mode promoting auxiliary adjustment absolute altitude when steel crane beam is installed by crane gear lifting, and this utility model is practical, can meet the similar Steel Structure Installation engineering higher to absolute altitude required precision.Save construction cost, structure is simple and easy to operate, reduces the job safety risk that hoisting and hanging brings, and effectively can play the effect regulating steel crane beam installed height mark, improves job safety coefficient.
Description
Technical field
The utility model relates to a kind of steel crane beam installed height mark adjusting device, belongs to Installation Technique of Steel Structure field.
Background technology
According to steel crane beam installed height mark control method in the past, what usually adopt is that crowbar single-point plays the regulative mode such as sled (crane girder for lighter in weight), auxiliary lifting lifting (crane girder for heavier-weight) of crane gear.According to the applicant understood, there is following problem in crane girder installed height mark control method in the past:
1, adopt crane gear to promote adjusting elevation, the activity duration is long, easily causes the wasting of resources, and needs configuration lifting special operation workers in steel crane beam lifting process, more on manpower drop into.
2, control method safety factor is lower in the past, crowbar easily occurs and slides and play the security risks such as grievous hurt.
3, the method for adjustment that single-point plays sled, crane gear assists lifting to promote, regulate accurate not to the absolute altitude of steel crane beam, be difficult to meet the higher engineering of steel crane beam absolute altitude requirement, and easily cause the longitudinal axis of steel crane beam to offset when adjusting, increase secondary adjustment workload.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides the special adjusting device that a kind of cost is low, applicability is strong, assembly operation is simple, safety is high.
In order to solve above technical problem, the utility model provides a kind of steel crane beam installed height mark adjusting device, comprises two jack, also comprises two clamps and supports channel-section steel; On described two clamps, inner side offers grafting gap in the same position at top, and all offers rectangular through-hole in the same position near bottom; Described support channel-section steel two ends are fixed by securing member through after rectangular through-hole, and described jack is arranged on the support channel-section steel between described two clamps.
The technical scheme that the utility model limits further is:
Further, the height that the grafting gap of described clamp is offered is slightly larger than steel crane beam bracket top flange gripper shoe thickness, described clamp is plugged in the gripper shoe of described steel crane beam bracket top flange by grafting gap, achieves effective connection of clamp and bracket top flange base plate.
Further, the distance between described two clamps is slightly larger than the width of steel crane beam bracket bottom flange gripper shoe.
Further, described clamp adopts steel plate to make.Overall structure good rigidly, manufacture craft is simple.Supporting channel-section steel connects into as a whole by two clamps, jack is laid by support channel-section steel, is realized the adjustment of crane girder end face absolute altitude by the jacking stroke of synchronous adjustment jack.
Further, also stiffener is installed with in the below of steel crane beam bracket top flange gripper shoe.
The beneficial effects of the utility model are: the utility model changes the mode promoting auxiliary adjustment absolute altitude when steel crane beam is installed by crane gear lifting, and this utility model is practical, can meet the similar Steel Structure Installation engineering higher to absolute altitude required precision.Save construction cost, structure is simple and easy to operate, reduces the job safety risk that hoisting and hanging brings, and effectively can play the effect regulating steel crane beam installed height mark, improves job safety coefficient.

Detailed description of the invention
embodiment 1
A kind of steel crane beam installed height mark adjusting device that the present embodiment provides, as shown in Figures 1 to 3: comprise two jack 1, also comprises two clamps 2 and supports channel-section steel 3; On two clamps 2, inner side offers grafting gap 4 in the same position at top, and all offers rectangular through-hole 5 in the same position near bottom; Support channel-section steel 3 two ends to be fixed by latch 8 through after rectangular through-hole 5, jack 1 is arranged on the support channel-section steel 3 between two clamps 2.The height that the grafting gap 4 of clamp 2 is offered is slightly larger than steel crane beam bracket top flange gripper shoe thickness, and clamp 2 is plugged in steel crane beam bracket top flange gripper shoe 6 by grafting gap 4.Distance between two clamps 2 is slightly larger than the width of steel crane beam bracket bottom flange gripper shoe 10.
Stiffener 9 is also installed with below steel crane beam bracket top flange gripper shoe 6.
The size of clamp and fluting size are according to the weight of required crane girder, the operating space of jack and determining.Support selecting according to the weight of required crane girder and determining of channel-section steel and jack.When carrying out absolute altitude and regulating, realized by the jacking stroke adjusting jack.
Install and use in process, be first arranged on respectively by two pieces steel clamp 2 on the bracket top flange base plate 6 that need adjust below crane girder 7, two clamp 2 spacing are slightly larger than the width of steel crane beam bottom wing listrium; Afterwards support channel-section steel 3 is arranged on two clamps 2, composition center rest structure.Jack 1 is positioned over and supports on channel-section steel, realized the adjustment of steel crane beam installed height mark by the jacking stroke of synchronous adjustment jack 1.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
