Description
Technical field
The utility model relates to a kind of jointing of tabular component.
Background technique
Bear the joint of the tabular component of thrust load at present, especially bear the end connector of the carbon fiber composite coiled rod of La-La fatigue load, comprise male connection and several bolts, one end of male connection is tuning fork shape, during use tabular component is inserted in the sound fork groove of male connection, be horizontally through the bi-side and the tabular component of male connection tuning fork shape end with several bolts, and with bi-side and tabular component clamping, thereby tabular component and male connection are coupled together.This joint must punch on tabular component when using, and can cause that stress is concentrated, has reduced the static strength and the fatigue strength of tabular component, and fracture accident takes place easily.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, static strength with the fatigue strength height, be connected reliable joint.
For achieving the above object, the utility model is taked following design proposal: a kind of joint is characterized in that: it comprises:
One staving, its opening is provided with internal thread, and described staving madial wall lower surface is conical surface, and described staving bottom is provided with rectangular through-hole;
Two cross sections being located in the described staving are semicircular wedge-shaped blocks, two described wedge-shaped blocks vertical planes are ladder surface, the lower surface of described ladder surface is carved with decorative pattern, and two described wedge-shaped blocks vertical planes are staggered relatively and form the conical external surface match with described staving conical surface;
Bi-side, one top are bonded with the tabular component of a pad respectively, and described tabular component cross section is a rectangle, and described tabular component passes described staving bottom through-hole and places between the lower surface of two described wedge-shaped blocks ladder surfaces;
One with the bolt of described staving internal thread bolt, it tightly withstands on the end face of two described wedge-shaped blockss;
One male connection, described male connection middle part outer surface is provided with spanner flat, described male connection up and down two ends is respectively equipped with outside thread, and the outside thread of described male connection by the lower end is connected with described staving internal thread and is positioned at above the described bolt.
Described pad is copper pad or aluminium matter pad or steel shim or glass fibre pad.
The top of described bolt is provided with driving hole.
Described pad outer side surface is carved with decorative pattern.
The utility model has the advantages that: the utility model is simple in structure as can be known by above-mentioned design proposal; owing to be bonded with a pad respectively in the tabular component bi-side; tabular component is played a very good protection; and the lower surface of pad and outer side surface and wedge-shaped blocks ladder surface is carved with decorative pattern; increased the frictional force between pad and the wedge-shaped blocks; in addition when assembling; utilize special arrangement or bolt to apply the pressure of suitable size at two wedge-shaped blocks top end faces; the wedge-shaped blocks outer surface is closely contacted with the staving internal surface; and generation certain elastic deformation; after laying down top pressure; residual tension and pressure stress have been produced on staving inwall and the wedge-shaped blocks respectively; thereby tabular component tightly is clipped between two voussoirs; whole static strength and fatigue strength height; connect reliably, and can prevent that by the upper-end surface that bolt withstands on two wedge-shaped blockss two wedge-shaped blockss from retreating.

Embodiment
As shown in Figure 1, the utility model joint is characterized in that: it comprises:
One staving 1, its opening is provided with internal thread 2, and staving 1 madial wall lower surface 3 is conical surface, and staving 1 bottom 4 is provided with rectangular through-hole 5;
Two cross sections being located in the staving 1 are semicircular wedge-shaped blocks 6, two wedge-shaped blockss, 6 vertical planes 7 are ladder surface, the lower surface 8 of described ladder surface is carved with decorative pattern, and two wedge-shaped blockss, 6 vertical planes 7 are staggered relatively and form the conical external surface that matches with staving 1 conical surface;
Bi-side, one top are bonded with the tabular component 10 of a pad 9 respectively, and tabular component 10 cross sections are rectangle, and tabular component 10 passes staving 1 bottom 4 through holes 5 and places between the lower surface 8 of two wedge-shaped blockss, 6 ladder surfaces;
One with the bolt 11 of staving 1 internal thread 2 bolts, it tightly withstands on the end face of two wedge-shaped blockss 6.
During use, utilize special arrangement or bolt to apply the pressure of suitable size at the end face of two wedge-shaped blockss 6, two wedge-shaped blockss, 6 outer surfaces are closely contacted with staving 1 internal surface, and generation certain elastic deformation, after laying down top pressure, residual tension and pressure stress have been produced respectively on staving 1 inwall and the wedge-shaped blocks 6, thereby make two wedge-shaped blockss 6 clamp tabular component 10, whole static strength and fatigue strength height, connect reliably, and can prevent that by the upper-end surface that bolt 11 withstands on two wedge-shaped blockss 6 two wedge-shaped blockss 6 from retreating;
One male connection 12, male connection 12 middle part outer surfaces are provided with spanner flat 13, and male connection is respectively equipped with outside thread 14 in two ends about in the of 12, and the outside thread 14 of male connection 12 by the lower end is connected with staving 1 internal thread 2 and is positioned at bolt 11 tops.
The top of bolt 11 is provided with driving hole 15.
