The multifunctional pressure/draw bar for the positioning of the corrugated steel webs is simple and effective, and can save materials, reduce construction procedures, accelerate construction progress and guarantee the precision and stability of the positioning.
Description
Technical field
The utility model relates to the Wavelike steel webplate field of bridge construction, a kind of multi-functional strut and tie that uses in particularly a kind of Wavelike steel webplate location and installation process.
Background technology
Obtained using comparatively widely at France, Japan and other countries Wavelike steel webplate bridge, it is to adopt the thick steel plate of 10-30mm, be bent into waveform, replace the thick concrete web of 30-80cm in the box beam structure, when reducing the superstructure deadweight, improve structural seismic performance and prestressing force efficient, thoroughly solve the problem that ordinary construction is striden footpath continuous beam and continuous rigid frame median ventral plate concrete cracking greatly.Its bridge construction form that is suitable for of Wavelike steel webplate is also very extensive, to continuous rigid frame, arrives part cable stayed bridge even suspension bridge from simply supported beam, continuous beam again, has powerful adaptive capacity, is a kind of novel bridge structure that is worthy to be popularized.
In such bridge construction, the precision of Wavelike steel webplate installing and locating is most important, and it is linear and stressed to be directly connected to bridge construction, and bridge durability.And conventional positioning supporting frame adopts big shaped steel or sets up scaffold, except that the expense material of taking a lot of work, also can take big quantity space and influence follow-up construction.
Summary of the invention
The purpose of this utility model is in order to reduce the working procedure of conventional way, reduce the complexity of positioner, and the resistance to overturning of enhancing Wavelike steel webplate, the multi-functional strut and tie of a kind of Wavelike steel webplate location usefulness is provided, this strut and tie is simply effective, can economical with materials and working procedure, accelerating construction progress guarantees that the location is accurately and stable.
The technical scheme that its technical problem that solves the utility model adopts is: design a kind of Wavelike steel webplate and locate multi-functional strut and tie, which comprises at least two fixing Wavelike steel webplates between the inside and outside coxostermum of case beam, it is characterized in that: strut and tie has been threaded between the interim bolt hole of two Wavelike steel webplate front ends.
The twice strut and tie has been threaded between the interim bolt hole of described two Wavelike steel webplate front ends.
Described strut and tie is the thick-walled seamless steel pipes of rod shaped structure.
The two ends of described strut and tie all are fixedly connected with the support backing plate, support the middle perforate of backing plate, support the backing plate inboard and be fixed with nut, nut bore is over against the perforate of supporting backing plate, strut and tie runs through pad, bolt hole, support backing plate successively by bolt and is connected with nut thread between the interim bolt hole of two Wavelike steel webplate front ends.
The length of described strut and tie equals the clear distance of two Wavelike steel webplates.
The beneficial effects of the utility model are: the strut and tie that has been threaded between the interim bolt hole of two Wavelike steel webplate front ends, when two Wavelike steel webplates had the trend of distortion to the inside, the strut and tie pressurized played the effect of support.When two Wavelike steel webplates have the trend of distortion laterally, bolt tension by the strut and tie end, restrained deformation, the acting in conjunction of tension and compression member guarantees the Wavelike steel webplate locating effect, effectively simple, easy for installation, do not need big machinery to cooperate, can save working procedure, accelerating construction progress guarantees that the location is precise and stable.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Fig. 1 is that Wavelike steel webplate is located multi-functional strut and tie layout schematic diagram;
Fig. 2 is that the section that Wavelike steel webplate is located after multi-functional strut and tie is installed is arranged schematic diagram;
Fig. 3 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: 1, Wavelike steel webplate; 2, strut and tie; 3, bolt hole; 4, bolt; 5, nut; 6, support backing plate; 7, pad.
The specific embodiment
Locate multi-functional strut and tie as the Wavelike steel webplate of Fig. 1, Fig. 2 and arrange shown in the schematic diagram, locate multi-functional strut and tie, satisfy positioning requirements in two Wavelike steel webplates, 1 disposed inboard twice.
Be fixed with the twice strut and tie 2 that has been threaded between the interim bolt hole 3 of 1, two Wavelike steel webplate 1 front end of two Wavelike steel webplates between the inside and outside coxostermum of case beam, strut and tie 2 is the thick-walled seamless steel pipes of rod shaped structure.
As shown in Figure 3, the two ends of strut and tie 2 all are welded with supports backing plate 6, support backing plate 6 middle perforates, support backing plate 6 inboards and be welded with nut 5, nut bore is over against the perforate of supporting backing plate 6, strut and tie 2 is between the interim bolt hole 3 of two Wavelike steel webplate 1 front ends the time, pass bolt hole 3, support backing plate 6 middle perforates by bolt 4 and pad 7, final bolt 4 is threaded io in the nut 5, two Wavelike steel webplates 1 are coupled together, by 4 modes that adopt inner support to draw that tight a bolt, guarantee the stable of two steel web 1 spacings outward.
The length of strut and tie 2 equals the clear distance of two Wavelike steel webplates 1, and after the installation, when two Wavelike steel webplates 1 had the trend of distortion to the inside, strut and tie 2 pressurizeds played the effect of support.When two Wavelike steel webplates have the trend of distortion laterally, by bolt 4 tensions of strut and tie 2 ends, restrained deformation, the acting in conjunction of tension and compression member guarantees Wavelike steel webplate 1 locating effect.
