Description
Technical field
The utility model belongs to Wavelike steel webplate technical field, relates to a kind of Wavelike steel webplate dumbbell shape shear connector.
Background technology
Along with the continuous progress and development of society, the especially develop rapidly of transportation, what allow the go off daily of people become is very convenient; But, along with popularizing of the vehicles, be also growing with each passing day for demands such as traffic route bridges, especially in the area that some population density are larger, the serious quality of life having had influence on people of traffic congestion and constrain urban development, improves traffic, becomes the most important thing.Along with the development of road and bridge form of structure, therefore corrugated web bridge arises at the historic moment.
Prestressed concrete composite box-girder with corrugated steel webs is that a kind of important transverse direction bears combined member, by concrete is combined with Wavelike steel webplate, the bending resistance of concrete roof and floor and Wavelike steel webplate shearing resistance, thus make combining structure give full play to the advantage that steel tensile property is good and concrete anti-compression performance is good.In Wavelike steel webplate combined bridge, Shear connection key, as one of important primary structure member, has the function of the longitudinal shear transmitted between steel web and concrete frange plate, also plays the effect preventing concrete frange plate and Wavelike steel webplate to be vertically separated simultaneously.At present, the shear connections key class used in Wavelike steel webplate bridge is more, for PBL connecting key, the more complicated connector of ordinary construction all has the effect of good anti-bridge direction of principal axis shearing, anti-transverse bending moment, but this brings very large trouble just to the making of shear connector and construction, then reduces its economic benefit; Simultaneously, due to many employings prefabrication field erected form when Wavelike steel webplate is installed, traditional Wavelike steel webplate when mounted, usually plain bolt bar is adopted to connect between two pieces of Wavelike steel webplates, overlap adopts the form of Double-face adhesive pin welded seam, bolt hole is circular port, the impact of execution conditions and construction level is subject in field-mounted process, when causing installing there is certain error in Wavelike steel webplate location, the deviation of especially vertical elevation and lengthwise position, finally can affect steel web stress and full-bridge line style.When traditional steel web adopts bolt to overlap, bolt hole is generally circle, and adjust the problem of difficulty when this will cause Wavelike steel webplate to occur error in installation process, this improves the requirement to technical level in work progress undoubtedly, increases difficulty of construction.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of by edge of a wing steel plate and Wavelike steel webplate being welded together, and edge of a wing steel plate is provided with dumbbell shape through hole, both the connecting key as flush type participates in shearing resistance, again by longitudinal restraint reinforcing bar by the resistance to overturning enhancing structure, efficiently solve the problem existing for PBL connecting key that structure is comparatively complicated; The two the semicircles simultaneously circular bolt holes on steel web being changed into horizontal direction add rectangular opening, make shank of bolt can have certain adjustment space, front and back in the horizontal direction.
The purpose of this utility model is achieved in that
Wavelike steel webplate dumbbell shape shear connector, comprise Wavelike steel webplate 1, the edge of a wing steel plate 2 welded together with Wavelike steel webplate 1, described edge of a wing steel plate 2 buries people's concrete parts and is provided with dumbbell shape through hole 4, be installed with longitudinal restraint reinforcing bar 3 in dumbbell shape through hole 4, described longitudinal restraint reinforcing bar 3 is fixedly connected with the plain bars in concrete roof;
Described edge of a wing steel plate 2 adopts twin fillet wolt to weld with Wavelike steel webplate 1; Longitudinal restraint reinforcing bar 3 adopts colligation with the plain bars in concrete roof or is welded and fixed;
Described dumbbell shape through hole 4 is three parts respectively, are circular above, and interposition rectangle is oval below;
Described dumbbell shape through hole 4 is arranged along edge of a wing steel plate 2 longitudinal direction;
Described Wavelike steel webplate 1 is provided with two semicircle and adds rectangle bolt hole 5; Add the shank of bolt 8 in rectangle bolt hole 5 through two semicircle, be placed on spacer for bolt 6 on shank of bolt 8 and with shank of bolt 8 with the use of nuts 7;
Described two semicircles add rectangle bolt hole 3 and elliptical aperture structure can be adopted to replace.
positive beneficial effect:the utility model is by establishing edge of a wing steel plate on Wavelike steel webplate top, and edge of a wing steel plate Transducers Embedded in Concrete part is provided with dumbbell shape through hole, longitudinal restraint reinforcing bar is through in hole, and in longitudinal restraint reinforcing bar and concrete slab, plain bars is by colligation or be welded together; The reinforced binding that runs through through dumbbell nibs concrete around steel plate, make the concrete in hole be subject to three-dimensional constraint and then improve the shear behavior of structure, enhance the bonding strength between steel web and concrete, and compared with conventional P BL connecting key, its structure is comparatively simple, be conducive to the colligation of reinforcing bar in work progress, effectively shorten construction period; Circular port on Wavelike steel webplate is changed into after two semicircle adds rectangular opening or elliptical aperture, in overlap joint installation process, shank of bolt is longitudinally having certain scope of activities, convenient and temporary fixed when installing on the one hand, on the other hand when in installation process, error appears in the location of Wavelike steel webplate, can make adjustment in next block Wavelike steel webplate installation process, doing so avoids the accumulation of error, reduce the difficulty of construction, ensure that the quality of construction simultaneously better.
