Technical field
A kind of device being reliably connected for timber is the utility model is related to, is followed closely more particularly to a kind of triadius type member.
Background technology
Member nail is often used as hardware-joint in production and construction timber combines connection, and existing member nail is all solid list
Bar, during use in the straight connection of insertion two timber, makes two timber link together, due to nail tip side timber nail rod straight cutting into
Enter, stress is easy to pull-off and comes out, and connection reliability is low, how to be reliably connected using member nail realization and is still solved up for technology.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of triadius type member nail.
The technical solution adopted in the utility model is：A kind of triadius type member nail, it is characterised in that including core nail and side nail, core
Nail is equipped with nail rod and the head of a nail, and nail rod front end is equipped with nail tip, and nail rod tail end is connected with the head of a nail, 2/3rds length of nail rod rear portion
Arranged on left and right sides is respectively equipped with two parallel planes that symmetrical and spacing is nail rod diameter 2/1sts to three/3rd, puts down
Face is connected with anterior nail rod side cohesive position for the conical surface transition using nail rod axis as axis, and the conical surface is being followed closely along nail rod axis direction
Cap projected position forms two through holes；Side nail is two, and both sides nail leading portion is penetrated by two through holes respectively to be leaned against with nail rod
Together, nail front end in side is equipped with the mating surface coincideing with the conical surface, and both sides nail abuts in two planes of nail rod respectively, both sides nail and nail
The bar cross section that is close together is in solid circles, and side nail front end is equipped with chamfering.
Further, the side nail leading portion lateral surface is equipped with transverse groove.
Further, the side nail leading portion lateral surface is equipped with cannelure.
Further, 1/3rd length cross-sectional areas are less than rear 2/3rds length cross section face before the side nail
Product, and hither plane is leaned in thinning area.
The utility model is used for the connection between upper and lower two timber, first inserts both sides nail by head of a nail through hole respectively during use
Enter, the conical surface is coincide with mating surface, then put the cushion block on an overhead head of a nail on the head of a nail, cushion block be equipped with outside the head of a nail
The identical anastomosed aperture of side nail, side nail tail end top is only at anastomosed aperture bottom, and then pound with a hammer cushion block, and hammering into needs to connect in two timber
Contacted to the head of a nail with timber or to submerge wood surface one flat, then remove upset cushion block, cushion block is equipped with what is coincide with side nail tail end
Stomidium, makes side nail tail end insertion stomidium, then tapping cushion block makes side nail continue to intert to wood internal, makees in the conical surface and mating surface
It is inserted into respectively to two lateral bends in the timber lateral body of second piece of lower part with downside nail following, finally takes away cushion block and tap side nail tail end extremely
It is flat in the head of a nail one, realize three lockings, core nail and side nail are not easy pull-off, are connected firmly.
Brief description of the drawings
Fig. 1 is the utility model embodiment overall schematic.
Fig. 2 is the utility model embodiment band cushion block schematic cross-sectional view.
Reference numeral:Follow closely 1 side；2 nail rods；3 heads of a nail；4 nail tips；5 planes；6 conical surfaces；7 through holes；8 mating surfaces；9 chamferings；10
Cushion block；11 anastomosed apertures；12 stomidiums.
Embodiment
As shown in Figure 1, 2, triadius type member nail is for reliably connecting between upper and lower two blocks of timber for the utility model embodiment
Connect, equipped with core nail and side nail 1, core nail is equipped with nail rod 2 and the head of a nail 3, and nail rod front end is equipped with nail tip 4, and nail rod tail end is connected with the head of a nail,
The arranged on left and right sides of 2/3rds length of nail rod rear portion be respectively equipped with symmetrical and spacing for nail rod diameter 1 to three/3rd/
Two two parallel planes 5, can be with nail rod with anterior nail rod side cohesive position by cutting or extrusion forming, plane
Axis connects for 6 transition of the conical surface of axis, and the conical surface forms two through holes 7 along nail rod axis direction in head of a nail projected position；Follow closely side
For two, both sides nail leading portion is penetrated by two through holes respectively to be close together with nail rod, and side nail front end is equipped with what is coincide with the conical surface
Mating surface 8, both sides nail abut in two planes of nail rod respectively, and both sides are followed closely and nail rod is close together, and cross section is in solid circles,
Side nail front end is equipped with chamfering 9, and not bifurcated is oriented to when hammering into.
The utility model is used for the connection between upper and lower two timber, first inserts both sides nail by head of a nail through hole respectively during use
Enter, the conical surface is coincide with mating surface, then put the cushion block 10 on an overhead head of a nail on the head of a nail, cushion block be equipped with outside the head of a nail
The identical anastomosed aperture 11 of portion side nail, side nail tail end top only prevent bifurcated in anastomosed aperture bottom, protection side nail, and then pound with a hammer pad
Block, hammers into need to connect and is contacted in two timber to the head of a nail with timber or to submerge wood surface one flat, then removes upset cushion block, pad
Block is equipped with the more relatively shallow stomidium 12 coincideing with side nail tail end, makes side nail tail end insertion stomidium, then tapping cushion block makes side
