Abstract
The utility model discloses a span adjusting device including a jack (2), the jack (2) is arranged inside a fixing device (1), the fixing device (1) is fastened with a fixed end of the roofing beam to be adjusted through welding, the fixing device (1) is a steel plate with an I-shaped cross section, the middle part of the steel plate is provided with a rectangular empty groove, a top board (3) is welded at the end to be adjusted of the roofing beam, and the jack (2) and the top board (3) are formed into an axial telescoping device. Compared with the dragging rope or inverted chain span adjusting manner in the prior art, the span adjusting device provided has the advantages of simple structure, flexible and fast operation, and high span adjusting accuracy. The span adjusting device provided can be adapted to the adjustment of roofing beam span during the installation of a roofing purlin or the adjustment of column span during the installation of a crane beam.
Description
Technical field
The utility model relates to a kind of span adjusting device, relates in particular to be applicable to that real abdomen roof girder adjusts erecting device or be used for the adjustment erecting device of roof purline etc.
Background technology
In the metallurgical industry workshop building, usually can run into because the deviation of steel column verticality causes span or wheelbase deviation to cause member that situation of difficult is installed.At present, jack, the dilatory ropes of adopting carry out the adjustment of span more in construction, adopt this method because installation personnel and ground staff's connection problem and constructing operation difficulty often cause the waste of mechanical one-shift and constructor's the work holdup.
The utility model content
The technical problems to be solved in the utility model provides a kind of span adjusting device that is applicable to that real abdomen roof girder installation is adjusted, and solves the problem that the steel column deviation is adjusted constructional difficulties.
The utility model is achieved by following technical proposals:
A kind of span adjusting device, comprise jack (2), described jack (2) is arranged on fastening devices (1) inside, the moved end welding is not fastening with the roof girder one that needs to adjust for fastening devices (1), described fastening devices (1) is the steel plate of a cross section for " worker " font, described steel plate middle part is a rectangular configuration dead slot, and top board (3) is welded on the end that roof girder need be changed, and jack (2) constitutes the axial stretching device with top board (3).
Described top board (3) is a plane steel plate or " fourth " font steel plate.
During use, at first the moved end welding is not fastening with the roof girder one that needs to adjust with fastening devices; According to employed jack size top board is welded on the end that roof girder need be changed then, jack and top board constitute the axial stretching device; Jack one end is propped up fastening devices, and the other end props up top board, and the adjustment jack pushes up the spacing between two sections beams to installation dimension fixes beam.
The utility model reaches convenient, accurately adjusts the effect of span by the distance between jack regulation fixing apparatus and the top board.
The advantage that the utlity model has with beneficial effect is: the utility model span adjusting device is adjusted span with dilatory rope of the prior art or jack and is compared, its advantage is: equipment therefor is simple in structure, flexible operation is quick, span is adjusted degree of accuracy height, can be good at accelerating the structure installation progress.
The adjustment of post distance when the adjustment of roof girder span or crane girder were installed when span adjusting device of the present utility model was also installed applicable to roof purline.
Description of drawings
Fig. 1 is the utility model span adjusting device structural representation.
Fig. 2 is a schematic diagram before roof girder is adjusted.
Fig. 3 is a schematic diagram after the roof girder adjustment.
Wherein 1, fastening devices; 2, jack; 3, top board.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, span adjusting device of the present utility model, comprise jack 2, described jack 2 is arranged on fastening devices 1 inside, the moved end welding is not fastening with the roof girder one that needs to adjust for fastening devices 1, and described fastening devices 1 is the steel plate of a cross section for " worker " font, and described steel plate middle part is a rectangular configuration dead slot, top board 3 is welded on the end that roof girder need be changed, and jack 2 constitutes the axial stretching device with top board 3.That is: form a fastener by said fixing device 1, top board 3, reach the purpose of adjusting span with the collapsing length of adjusting jack 2.
As shown in Figures 2 and 3, at first fastening devices 1 need the moved end welding be not fastening with one, according to employed jack 2 sizes top board 3 is welded on the end that roof girder need be changed then, after all fixedly finish, jack 2 one ends are propped up fastening devices, the other end props up top board, adjustment jack 2 pushes up the spacing between two sections beams to installation dimension fixes beam, promptly reaches the purpose of adjusting span at fastening devices 1, top board 3 with the collapsing length of roof girder or the fixing back adjustment of column cap welding jack 2.Fastening devices 1 with the welding settled principle of top board 3 is: span is fixing less than the welding of design size homonymy, span is fixing greater than the welding of design size heteropleural.The scope of application of being adjusted is-50mm≤x (span bias)≤this scope of 50mm installation maximum deviation for " steel work inspection of quality standard " regulation.
In conjunction with the accompanying drawings the utility model has been carried out functional description, above-mentioned embodiment is only represented schematically.But at the scene in the practical application since the technician under inspiration of the present utility model, under the situation that does not break away from the utility model aim and claim institute protection domain, can also make other form, these all should belong to the row of protection of the present utility model.
Claims (2)
1. span adjusting device, comprise jack (2), it is characterized in that, described jack (2) is arranged on fastening devices (1) inside, the moved end welding is not fastening with the roof girder one that needs to adjust for fastening devices (1), and described fastening devices (1) is the steel plate of a cross section for " worker " font, and described steel plate middle part is a rectangular configuration dead slot, top board (3) is welded on the end that roof girder need be changed, and jack (2) constitutes the axial stretching device with top board (3).
2. according to the described span adjusting device of claim 1, it is characterized in that described top board (3) is a plane steel plate or " fourth " font steel plate.
