The specific embodiment:
With reference to Fig. 1, Fig. 2 and Fig. 3, steel framework splicing fastener comprises pin rod 1, pad 2 and Button Handle 3; Pin rod 1 one ends offer hook groove 12 with limited cap 11 on the other end pole face, this hook groove 12 can be processed by milling machine, and limited cap 11 can be formed by cold stamping, perhaps directly at pin rod 1 end solid welding one limited cap, perhaps pin rod is processed with thread segment, in the thread segment top nut of locking; Button Handle 3 is formed by the steel disc bending, have circular arc bending part 31, open and flat 32 and shank 33, firmly hand-held when shank 33 provides operation, and offer elongated slot through hole 34 at bending part 31, this elongated slot through hole 34 extends to open and flat 32, and elongated slot through hole 32 forms a buckle ring 35 in the end of bending part 31; Elongated slot through hole 34 width are greater than pin rod 1 diameter, to allow pin rod 1 pass this elongated slot through hole 34; Pad 2 is set on the pin rod 1, and is provided with elastic body between pad 2 and limited cap 11, and this elastic body can be plunger spring 4 or arc reed 5, this example is plunger spring 4, directly be set on the pin rod 1, an end is conflicted on limited cap 11, and the other end is conflicted at pad 2; Break away from pin rod 1 for fear of pad 2 and plunger spring 4, pin rod 1 is milled with spigot surface 13 on elastic body trip segment surface, offer the hole 21 suitable with pin rod 1 elastic body trip segment cross section on the pad 2, both engagement limits pin rod 1 rotations and pad 2 break away from, such as Fig. 2, in the time of can keeping operating like this, the hook groove 12 of pin rod towards, be beneficial to constructing operation.
During construction, an end of pin rod 1 buckle groove 12 is passed two adjacent steel frameworks 6, dot among the figure; Elongated slot through hole 34 on the Button Handle 3 is inserted in pin rod 1 and buckle ring 35 is entered in the hook groove 12, swinging Button Handle 3 flushes with steel framework 6 faces to open and flat 32, form the cam surface location structure, such as Fig. 3, when Button Handle 3 swings, by plunger spring 4 and Button Handle 3 elastic deformations that produce own, the distortion allowance that provides Button Handle bending part 31 to swing, both can allow Button Handle 1 fasten smoothly and put in place, and can guarantee that again adjacent steel framework 6 was by locking positioning state all the time.
With reference to Fig. 4 and Fig. 5, this example gonosome of being hit by a bullet is arc reed 5, and bow top 51 offers the eyelet that passes for pin rod 1, and arc reed 5 is set on the pin rod 1, conflicts on pin rod limited cap 11 in bow top 51, and two bow foots 52 are conflicted on pad 2.Arc reed 5 both can keep pad 2 to conflict on steel framework 6, and the surplus that has again distortion to retreat is beneficial to Button Handle 3 lockings or removes operation.In this example, also can be welded on the limited cap 11 at 51 at the bow top of arc reed 5, the cross section of perhaps bending the eyelet offered on the top 51 and pin rod 1 this section is suitable, avoids producing relative rotation between arc reed 5 and pin rod 1 and pad 2 threes.
In addition, pin rod 1 elastic body trip segment cross section also can be non-circular structure, such as square or hexagon, offers the hole 21 suitable with pin rod 1 elastic body trip segment cross section on the pad 2, and both cooperations also can limit pin rod 1 rotation and pad 2 breaks away from, and keep the globality of fastener; Pad 2 can be bathtub construction, also can be the planar structure.In the utility model, pad 2 plays the increase lifting surface area, and restriction pin rod 1 rise to the bait groove 12 towards, be beneficial to constructing operation, certainly also can omit pad, directly allow elastic body one end conflict on steel framework, perhaps following array structure.
With reference to Fig. 6, elastic body is arc reed 5, and bow top 51 offers the eyelet that passes for pin rod, arc reed 5 is set on the pin rod 1, conflicts on pin rod limited cap 11 in bow top 51, and two bow foots 52 are unsettled, after pin rod 1 passes adjacent steel framework 6, conflict on steel framework 6; For the hook groove 12 that makes the pin rod front end has directionality, namely impose spot welding at bow top 51 and 11 of limited caps and fix and get final product, both formed both and fixed, have again a directionality; Perhaps pin rod 1 adopts non-circular structure, is square square pin rod 1 such as the cross section, and bow top 51 has square orifice, and both also can form and prevent the cooperation of rotating.Limited cap 11 also can adopt nut, and double nut can be folded in arc reed 5 wherein.
