Abstract
The utility model relates to a filling type taper steel pin which belongs to a fastener. The utility model is composed of a conical pin, a conical pin bolt, a conical sleeve barrel and a buckle ring, wherein, the working surface of the conical pin or the conical pin bolt is a conical surface, the surface of an inner circle of the conical sleeve barrel is the conical surface, and an outer circle is a cylindrical surface. The upper opening point of the conical sleeve barrel is provided with an outer edge, an opening is arranged on a conical sleeve barrel wall in the axial direction, and the conical pin or the conical pin bolt and an inner hole of the conical sleeve barrel use the same taper. The conical pin or the conical pin bolt uses the form with a screw thread hole and can use the form with a screw rod. The utility model has the advantages that through the filling cooperation of a taper pin and the sleeve barrel, the diameter of the cylindrical surface outside the sleeve barrel is expanded, a pin hole is filled gradually, and a gap between a pin and a hole is reduced to enhance the whole rigidity of a connecting member.
Description
The utility model relates to a kind of full formula taper steel pin, belongs to fastening piece.
At present, the fastening piece of China's dismantling type steel structural, general whole pillar pin, the bolt of adopting, its diameter is generally than pin-and-hole, the little 1.0-2.0mm of keyhole diameter of connected node, the existence in gap between this pin of tie point (bolt)-hole is to cause connected node rigidity poor, produces the assembly group vertical non-resilient pin of structure (bolt) hole amount of deflection, influencing the lateral stiffness of assembly group structure and the basic reason of integral rigidity, simultaneously also is the major reason that causes the safe in utilization and poor stability of assembly group structure.For improving the rigidity of connected node, the trial of following three kinds of technical measures was arranged once: (1) increases pin, bolt diameter, reduces gap between pin (bolt)-hole, pin (bolt) hole.Though this mode has certain effect, influence the assembly group speed of dismantling type steel structural, be unfavorable for the requirement of dismantling type steel structural assembly group rapidity; (2) adopt new linkage structure, connect as adopting the frictional high-strength bolt.This mode is difficult to realize for dismantling type steel structural; (3) change pin, bolt type shape.Foreign project technician and manufacturer had released the fixed pin of several novelties in recent years---the trench digging pin, pin connection to mechanical parts is reformed, but its application diameter less (≤25mm), it is also bigger to dismantle difficulty simultaneously, is not suitable as the connection of dismantling type steel structural.
The purpose of this utility model provides a kind of full formula taper steel pin that can improve the integral rigidity of assembly group structure, and it also improves dismantling type steel structural safety in utilization and stability simultaneously.
The purpose of this utility model is to realize like this, it is made up of taper pin or circular cone pin, conical sleeve and clasp, the working surface of taper pin or circular cone pin is a conical surface, the internal circular surfaces of conical sleeve is a conical surface, cylindrical is the cylndrical surface, place suitable for reading at conical sleeve is provided with outer rim, is axially arranged with opening on the taper sheath barrel, and taper pin or circular cone pin adopt identical tapering with the conical sleeve endoporus.
Taper pin or circular cone pin are taper pin or circular cone pin with threaded hole.Taper pin or circular cone pin also can be the taper pin or the circular cone pin of band screw rod.
The tapering of taper pin or circular cone pin and conical sleeve is 1: 20-1: 30.
The thin-walled end wall of conical sleeve is thick to be the 1-2 millimeter.
The utility model utilizes the fastening principle of wedge, (taper pin is a taper in the nested effect of employing taper pin, sleeve, sleeve is an inner conical, the exterior cylindrical hollow body, taper pin adopts identical tapering with the sleeve endoporus), by changing the position of taper pin in sleeve, change the external diameter of composite structure (column type), realize that " filling " formula of dismantling type steel structural connects.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is embodiment's 1 an of the present utility model structural representation.
Fig. 2 is embodiment 2 a structural representation.
By embodiment shown in Figure 11 as can be known, it is made up of circular cone pin 6, conical sleeve 4, clasp 3, the working surface of circular cone pin 6 is a conical surface, and its tapering is 1: 20-1: 30, and the internal circular surfaces of conical sleeve is a conical surface, its tapering is 1: 20-1: 30, the conical sleeve endoporus adopts identical tapering with the circular cone pin, and the cylindrical of conical sleeve is the cylndrical surface, and place suitable for reading is provided with outer rim at conical sleeve, be axially arranged with opening on the taper sheath barrel, this mouthful formed by the cutting of wire cutting machine tool electrical spark.The thin-walled end wall of conical sleeve is thick to be the 1-2 millimeter.Illustrated circular cone pin is the circular cone pin of band screw rod.Also can adopt circular cone pin with threaded hole.In Fig. 1,1 is nut, and 2 is spring washer, and 5 is packing ring.
By embodiment shown in Figure 21 as can be known, it is made up of taper pin 11, conical sleeve 10, clasp 9.Embodiment's 2 difference from Example 1 are that it adopts taper pin 11, and taper pin 11 is taper pin with threaded hole (also can adopt the taper pin of band screw rod).In Fig. 2,7 is bolt, and 8 is spring washer.
By the utility model being detected test, test result such as following table:
| Test name | Analysis of experiments result |
| Material chemical composition and mechanical property | Meet the GB requirement |
| The fastening pin of taper is installed, dismounting | Install, dismantle (cooperation special tool) easily |
| Fastening pin 50 static tests of taper | Load 70 tons of perfect elasticities, 95 tons of taper pins are surrendered 70 tons of designing requirement permissible loads. |
| The fastening pin of taper uses repeatedly | Satisfy the requirement of using repeatedly |
| Taper pin connects six or four formula beam deflections | The basic pin-and-hole displacement amount of deflection of eliminating |
| 32 meter six or four double-deck beam deflection contrast of formula | The taper pin connects 9mm; Steel pin connects 42mm |
| 32 meter six or four double-deck beam lateral stiffness of formula | 1.5 tons of span centre lateral loads, displacement: the taper pin connects 88cm; Steel pin connects 237mm. |
| Double-deck eight or three pier flexural rigidityes contrast. | 30 tons of moments of flexure. rice, the span centre displacement: the taper pin connects 10.9mm; Bolt Connection 15.8mm. |
| The contrast of 10 meters pier top lateral displacement contrast bridge formation machine suspended wall (43m) amounts of deflection | 4 tons of loads, the taper pin connects: 89mm; Bolt Connection 72mm.The taper fixed pin ties and connects cantilever end deadweight amount of deflection and connect than steel pin and reduce about 400mm, accounts for the 85-90% of pin-and-hole displacement amount of deflection. |
Annotate: six or four formula beams, eight or three piers are arterial railway reassembling type war readiness materiel.
The utility model has the advantages that to be full of with the blunderbuss of sleeve by taper pin and cooperate, expansion sleeve external cylindrical surface diameter, reach and reduce even eliminate pin (bolt) hole displacement, reduce the vertical non-resilient amount of deflection of assembly group structure, improve the lateral stiffness of structure, thereby improve the integral rigidity of assembly group structure, it also improves safe, stable that dismantling type steel structural uses simultaneously; It also has the characteristics of installation, convenient disassembly.
