The specific embodiment:
The utility model is as shown in accompanying drawing 1～15.
A FRP member with ribbing, comprises the basic piece 1 of FRP, and basic longitudinally rib of slab 3 two parts of FRP on the basic base plate 2 of the basic piece 1 of the FRP FRP that is divided into bottom and its top, and the sidewall of the basic base plate 2 of described FRP has additional protruding key 4 and/or recessed key 5.The basic base plate 2 of FRP that is positioned at the basic piece 1 of FRP of end is only provided with one of them of protruding key 4 or recessed key 5 above, the basic base plate 2 of FRP that is positioned at the basic piece 1 of FRP of non-end is provided with protruding key 4 and recessed key 5 above simultaneously, size, the position phase coadaptation of protruding key 4 and recessed key 5, as shown in Fig. 1～2.According to the design size of the basic piece of FRP (1), in precast yard, select die needed size, the basic piece of FRP (1) go out to be transported to after mold forming job site carry out assembled, thereby effectively improved the efficiency of construction.
During the basic piece 1 of splicing FRP, according to the plate face size of FRP-concrete combined bridge deck in Practical Project, calculate the quantity of the basic piece 1 of required FRP; The basic piece 1 of FRP is arranged to placement in a certain order, and one deck adhesive material or bonding adhesive are smeared in the surface at the position that will be in contact with one another on protruding key 4 and recessed key 5; Finally the protruding key of a basic piece 1 of FRP 4 and the recessed key 5 of the basic piece 1 of another FRP are mutually combined, by being connected, form FRP member with ribbing. like this, the basic piece 1 of a plurality of FRP is the lower formation that is mutually the connected FRP member with ribbing with groove 5 by the protruding key 4 from arranging with it, as shown in Fig. 3～4.
On protruding key 4 and recessed key 5, have maybe and can have bolt hole 6.As shown in Fig. 7～9, bolt hole 6 is evenly distributed on protruding key 4 and recessed key 5 according to certain rule, and the bolt hole on protruding key 46 is identical with the aperture of bolt hole 6 on recessed key 5, position is mutually corresponding.While having bolt hole 6 on protruding key 4 and recessed key 5, just can in bolt hole 6, arrange the securing members such as bolt, latch or screw thread 7.The securing members such as bolt, latch or screw thread 7 further snap-in force each other while having strengthened basic base plate 1 splicing of FRP is set, retrain the lateral displacement of the basic piece 1 of FRP, effectively prevented the lateral sliding of the basic piece 1 of FRP when building facing concrete 11.
On the protruding key 4 of the basic piece 1 of FRP and recessed key 5, have bolt hole 6, when the basic piece 1 of splicing FRP, concrete splicing becomes step by step: according to the plate face size of FRP-concrete combined bridge deck in Practical Project, calculate the quantity of the basic piece 1 of required FRP; The basic piece 1 of FRP is arranged to placement in a certain order, and one deck adhesive material or bonding adhesive are smeared in the surface at the position that will be in contact with one another on protruding key 4 and recessed key 5; The protruding key of a basic piece 1 of FRP 4 and the recessed key 5 of the basic piece 1 of another FRP are mutually combined, note making protruding key 4 and recessed key 5 bolt hole above mutually to align simultaneously; In the bolt hole of alignment mutually, arrange the securing members such as bolt, latch or screw thread 7, the basic piece 1 of adjacent like this FRP forms FRP member with ribbing by being connected.Like this, protruding key 4 and the groove 5 that between the basic piece 1 of adjacent FRP, not only can arrange by self interconnect, can also make by the fastening effect of the securing members such as bolt, latch or screw thread 7 effect connecting further strengthen, guarantee that FRP-concrete forms the stress performance of bridge deck.
The basic base plate 2 of FRP substantially longitudinally has at least one to adopt hollow section form in rib of slab 3 with FRP.The structural representation of the basic base plate 2 of FRP that Fig. 1～8 are hollow section form and the basic longitudinally basic piece 1 of FRP that rib of slab 3 forms of FRP of solid section form; The structural representation of the basic base plate 2 of FRP that Figure 10～12 are solid section form and the basic longitudinally basic piece 1 of FRP that rib of slab 3 forms of FRP of hollow section form; The structural representation of the basic base plate 2 of FRP that Figure 13～14 are hollow section form and the basic longitudinally basic piece 1 of FRP that rib of slab 3 forms of FRP of hollow section form.The basic base plate 2 of FRP of hollow section form or and the basic longitudinally rib of slab 3 of the FRP of hollow section form can reduce material usage, improve the mechanical property of member.
The basic longitudinally cross sectional shape of rib of slab 3 of FRP is rectangle or T shape.The basic longitudinally cross sectional shape of rib of slab 3 of FRP shown in Fig. 7～9 is rectangle, and the basic longitudinally cross sectional shape of rib of slab 3 of all the other FRP shown in the drawings is T shape.The basic longitudinally rib of slab 3 of FRP of rectangular shape makes the section form of the FRP member with ribbing of formation be inverted T-shaped, as shown in Figure 8, Figure 9; The basic longitudinally rib of slab 3 of FRP of T shape shape makes the section form of the FRP member with ribbing of formation be I-shaped, as shown in Fig. 3～4.The basic longitudinally rib of slab 3 of FRP can be used as shear key, and the existence of rib of slab has obviously increased the contact area of FRP member with ribbing and facing concrete 11, has significantly improved the shear behavior of superposed surfaces.
FRP is basic is longitudinally provided with cross through hole 8 on rib of slab 3, as shown in Fig. 4, Fig. 9, Figure 11, Figure 12, Figure 14, cross through hole 8 is arranged on the basic longitudinally rib of slab 3 of FRP according to certain rule, its cross sectional shape is circle, ellipse, arc, polygon, wherein, the cross sectional shape of the cross through hole 8 in Fig. 4, Fig. 9, Figure 11 is oval, the cross sectional shape of the cross through hole 8 in Figure 12 is polygon, hexagonal cross sectional shape specifically, the cross sectional shape of the cross through hole 8 in Figure 14 is circular.In rib of slab, set up cross through hole 8, like this, cross through hole 8 internal surface layer concrete 11 form " pin " effect with rib of slab, have increased the mechanical snap power of FRP member with ribbing and facing concrete 11, have effectively improved the shear behavior of contact surface.
When adopting the basic longitudinal rib of slab 3 of FRP to be the basic piece 1 of FRP of hollow section form, sleeve 9 need to be inserted in cross through hole 8, as shown in Figure 11～12.Sleeve 9 adopts hard material to be made, and the cross sectional shape of its cross sectional shape and cross through hole 8 adapts.If sleeve 9 length are L, the basic longitudinally outer rim width of rib of slab 3 of the FRP of hollow section form is b, and inner edge width is a, as shown in figure 11; Or the outer rim overall width after the basic longitudinally rib of slab 3 of the FRP of hollow section form is assembled is b, inner edge overall width is a, as shown in figure 12, and a<L≤b.Arranging in the hollow parts of the basic longitudinally rib of slab 3 of FRP that facing concrete in the time of can preventing from building enters hollow section form of sleeve 9.
As shown in figure 15, in cross through hole 8, interspersed cross-perforating reinforcing bar 10, has realized horizontal arrangement of reinforcement, has improved the stress performance of FRP and concrete combined bridge deck.Finally, on the FRP member with ribbing of assembled formation, build facing concrete 11, formed the bridge deck that FRP combines with concrete.Now, cross-perforating reinforcing bar 10, the basic longitudinally rib of slab 3 of FRP and the facing concrete 11 flowing in cross through hole 8 form " pin " effect, increased the mechanical snap power of FRP member with ribbing and facing concrete 11, effectively improve the shear behavior of contact surface, guaranteed the integral working of FRP-concrete combined bridge deck.
