Abstract

The present invention discloses a timber connecter which comprises a pair of pointed nails allocated on the end part of one rod part, wherein the pointed nails are positioned in planes which basically make a right angle. In this way, the connecter can be used for correspondingly connecting two adjacent timber members which are perpendicular to each other, and the pointed nails and a part of an adjacent rod make an acute angle. In this way, the pointed nails and the rod can be easily struck in the timber members, a second pointed nail is gradually thinned from the axis of a first pointed nail to the outer end, and the rod part rotates around the first pointed nail which is struck inside as the second pointed nail is completely struck inside. Accordingly, the timber members are dragged together.

Description

Timber connecters

The present invention relates to connectors for timber and to its improvement.

Traditional timber structure is to utilize nail to fix connection between the timber structural member.Because nail is bearing on the shearing force very effectively, so this connection of nailing generally has enough intensity, but that its relatively poor tension is dialled power is irresistible as the load that lifts that whirlwind produced.Therefore bolt formula bolt and similar link are incorporated in the modern structure,,, have increased cost and made this structure become complicated though in use they are effectively so that it can resist high wind load.

Pin assembly connecting plate (gang-nail connector plates) also is used for forming between the adjacent bonds member and connects, yet up to the present, this connection also can't provide such being fastenedly connected, and guarantees promptly that also the member that uses this link to build up can resist high wind load and need not additional press holder.In addition, the pin assembly link of numerous types is all than expensive and be only applicable to special applications.

Other also has been used for timber spare is linked together as the link that is curved bar nail form, yet, because link is existed difficulty to obtain required structure connection with correct positioning and fixing to timber spare, so these links are not very successful.

The present invention is to be purpose to improve above-mentioned defective and to provide through improved connectors for timber, and this kind link in use is safe and reliable and effective.

By aforesaid and other purposes as seen, of the present inventionly mainly belong to the link that adjacent timber spare is linked to each other in a certain respect, and the present invention includes:

A rod that has hinged nail, this hinged nail are used for described rod is located with respect to a timber spare and described link can rotate around this hinged nail relative to its link position.

A spike that extends from described rod, rod that part of that is adjacent to described spike thus may extend on the one side of adjacent timber spare, thrusts described this one side with described spike,

The adjacent portion of described spike and described rod forms an acute angle.

The free end of spike preferably ends at the outside of camber line, this camber line be spike connecting end relatively its link position is drawn around hinged nail.Above-mentioned acute angle is better in 60 to 85 degree angular regions, and preferably 75 to 85 degree angular regions by knocking the contiguous place at bonding point between spike and the rod, can make spike enter in the timber spare with very little expansion like this.

Distance from the spike outer end to hinged nail is more preferably greater than following closely to the distance of spike and excellent junction point from hinged.This set can cause a kind of dragline of rod owing to the active force of second spike being squeezed into another timber spare side.Preferred version also comprises spike constituted to have the sharp end of a scalpriform, and this to forming an inclined-plane on the spike face of hinged nail, is used for increasing the dragline of rod throwing operating process into above end.

In preferred embodiment of the present invention, rod and spike are that the one segment length bending of line taking material forms, and rod is flexible, and therefore when spike was substantially vertically squeezed into the side of timber spare fully, rod was with respect to the flexible skew of spike, thereby formation is from clamping action.

Described spike preferably also constitutes second spike, articulated mounting then comprises first spike that is connected with second spike by rod, each spike is located substantially in a pair of corresponding flat that is on the plane that angle extends, link promptly can be used for connecting timber spare like this, and these timber spares have the plane separately that the angle of being in is provided with.In a preferred embodiment, each plane is vertical basically, thereby available link connects obverse each the timber spare that contains mutual rectangular setting.

Each face of the rod of contiguous spike for well, connects the adjacently situated surfaces of timber spare on concordant so that make it abut against them with the plane.For this purpose, wire rod can be circular cross-section, and this cross section can be deformed processing to produce planar section in the zone of contiguous spike, and perhaps wire rod also can be the rectangular cross-section profile and twisted at the middle part of spike.

Rod is a curved rod preferably, and the adjacent part of each spike and curved rod constitutes an acute angle.Acute angle between the rod and second spike is 75 to 85 degree angular regions preferably, and first spike then is to get a curved in length from the wire rod that constitutes the rod and second spike to form.Rod comprises two sections straight portion.They are to form to another extension from each corresponding spike, the rod part is on the plane of containing first spike and with the cornerite between 115 to 165 degree and links to each other, so in use, rod part in abutting connection with first spike can be put down on the plane that leans against the first timber spare, simultaneously, rod part away from first spike then can extend across this timber spare, so that second spike engages with another timber spare on the first timber spare.

In another embodiment of the present invention, rod can comprise an annular portion, and it can walk around an elongate articles, and this ring part constitutes fixing device, thereby this elongate articles can be fixed on the adjacent timber spare, and spike then is driven in this timber spare.Preferred version ring part for this reason is a trip ring.Rod stops at another spike place of leaving spike, and this another spike and above-mentioned spike are separated by an intersegmental distance and are driven into institute's grafting materials and parts.Two spikes are with substantially parallel extension, and form acute angle for well with each corresponding neighbouring part of rod, and they can be driven into the same plane of institute's grafting materials and parts like this.

Spike can be formed by the length of wire bending, and rod then can be flexible, and when spike substantially vertically was driven into a side of timber spare, rod can flexiblely be offset with respect to spike, and its angle is in the scope of 75 to 85 degree.Annular portion comprises two sections straight portion and one section straight anastomosis part of extending to spike, two sections straight portion are extended to the end of anastomosis part by corresponding spike, the timber that has plat surface like this can join with above-mentioned anastomosis part, and the load path from the anastomosis part to spike is then straight as far as possible.

Preferred version is, perpendicular distance from the axis of described anastomosis part to described each spike should have obvious difference, this different distance is at least the twice of spike diameter, so just a pair of link can be squeezed into a relative two sides than the veneer materials and parts, and the danger that two relative spikes meet can not appear, can be in a location yet the excessive rhegma of timber fiber.By each spike part of different length is provided, or between spike part and anastomosis part, form different amount, or both combinations, spike is arranged on the different distance of above-mentioned anastomosis part axis.

For making the present invention easier to understand and implementing, now referring to the accompanying drawing that exemplary embodiments of the present invention is described, wherein:

Fig. 1 is the diagram that the present invention typical case uses;

Fig. 2 is the diagram of Another Application of the present invention;

Fig. 3 is the geometric figure of preferred embodiment of the present invention;

Fig. 4 is the installation diagram of link shown in Figure 3;

Fig. 5 is the diagram of further embodiment of this invention;

Fig. 6 and 7 illustrates according to a kind of ring-like link of the present invention.

As shown in Figure 1, link 10 of the present invention can be used for being fixed together being in the timber spare 8 and 9 that the right angle is close together.For this purpose, used four links 10, they are configured in each corresponding side surface of the corresponding timber spare that will link together.

As shown in Figure 3, each link 10 comprises a curved rod 11, and it has

respective end portions

12 and 13, and

end

12 and 13 is arranged in first plane shown in frame of broken lines 14 and is in about 150 degree angles extends.Certainly this angle is that to be suitable for special applications be variable.This angle is to be provided with like this, and when end 12 rested on the side 15 of a timber spare 9, the other end 13 extended on the side 16 of adjacent timber spare 8, so that link 10 can engage at this.

First spike 17 is 12 to extend internally from the end in plane 14 substantially, and it extends with adjacent end portion 12 and is angle " A " in the present embodiment, and angle " A " is comparatively suitable with 80 degree, and it can change as mentioned above certainly.

Link 10 also comprises second spike 18, and spike 18 is positioned at another plane shown in the frame of broken lines 19, and extend near an angle of 90 degrees on it and plane 14, the axis 20 of second spike 18 with shown in the axis 21 of the other end 13 form an acute angle.As shown in Figure 2, end 13 can be in the distortion of 22 places, so that walk around the link of overlapping.

Attention is referring to Fig. 4, the acute angle that forms between first spike 17 and end 12 has an ancon section 23 as can be seen, this ancon section is easy to use by 24 hammers of representing and knocks, so that spike 17 is knocked in following timber spare 9, the side 15 of the relative timber spare of spike meets at right angles substantially or becomes acclivitous angle to thrust in the timber spare 9 relatively like this.

Be appreciated that the latter in use tilts if spike 17 forms obtuse angles with end 12, the end face of its relative hammer deflection that makes progress like this so that the impact energy of hammer directly facing to spike rather than facing to spike at interval on any of rod of one section.Might spike be to carry out side 15 also, owing to be applied to the pull up result of rod on 11, just can not form effective connection and to stop the dial-out of spike 17 in downward-sloping mode.

In addition, when spike 17 opposite flanks 15 when entering timber spare 9 substantially at right angles, before spike 17 is all knocked in the final position, this excellent knee shape portion 25 will contact with the last corner angle of timber spare.After knee shape portion 25 and corner angle 26 come in contact, beat flexiblely deflection of underpart 12 that spike 17 will cause rod 11 again, so that underpart 12 can be moved inwards and be abutted against on the side 15 concordant.This resilient bias will keep a kind of fastening as the clamp shape for the timber spare 9 between knee shape portion 25 and the spike 17, and this fastening will make link 10 keep using the state that engages for the angle of timber 9.

After first spike 17 was knocked in timber 9, it promptly constituted an articulated mounting, and excellent portion 13 can rotate around this articulated mounting.After 13 relative first spikes, 17 rotations of end, the ancon section 29 that gets final product align bar and spike node top is knocked, so that second spike 18 enters timber spare 8.

The setting of link 10 is like this, the outer end 30 and the distance between the ancon section 23 of second spike 18 are bigger than the distance between ancon section 23 and the ancon section 29, also are the outside that the camber line 40 that the radius 41 of drawing through ancon section 23 relative first spikes 17 marked is dropped in outer end 30.Like this since ancon section 29 be drawn towards and thrust initial point, the active force that second spike 18 is knocked in side 16 can make timber spare 8 downwards with 9 firm the engaging of timber spare.This active force can further increase because of cutter type end 31 structures, at the downside of spike 18 inclined-plane being arranged on the end 31 is 32, therefore inlet point to the side 16 of spike 18 is to be in to the ultimate range of timber spare 9, and the connection of spike 18 is inserted and just timber spare 8 and 9 is pulled in together like this.

Second spike 18 also is arranged to opposed end 13 and is an acute angle, so in use can be owing to joining of end 13 skew occurring with contiguous towards the slightly a bit dislocation of knocking of spike 18.

Non-collimation angle shown in Fig. 4, this link 10 keep static with initially install and maintain with the effective position contacting of hammer on, that is exactly the spikes of 15 extensions from ancon section 23 towards end face and the position of end 12, yet, link 10 remains at first can be along better on a certain position that direction shown in the arrow " I " is rotated, so that adjust first spike 17 near the required angle of thrusting, this angle slightly upwards is partial to side 15 or shape rectangular with it.Because rod can extend under the acute angle situation, so the insertion that spike is the oblique angle that dips down is unlikely.

Shown in Figure 5 is the use of relevant link 50, this link at spike 51 and rod the relation between 52 similar to link 10 on the configuration, still, rod 52 is longer, so that rod can be crossed over centre timber spare 53 and

timber

54 and 55 is linked together.

Fig. 6 and 7 shows the bridge-type link 60 that is adopted, and can be used for a batten 61 is secured on rafter wood 62 or the similarity piece.Present embodiment is also very similar to link 10 on the configuration in relation between spike 63 and the excellent portion 64.But in the present embodiment, two spikes 63 are the configuration that is parallel to each other basically, and are inserted into the same side of timber 62.Spike 63 contains the plane inclination of excellent portion 64 with about 80 degree angles, so that it is driven in the timber 62.Rod portion 64 has a central part 65, is used for the back of batten 61 is connected with the joint 66 that the two ends of central part 65 are received on the spike 63 mutually.As shown, link 60 is suitable for paired use.

As shown in Figure 7, the outside of camber line 71 is dropped in the outer end 67 of spike 63, and this camber line is by drawing near the radius that decide at the center 72 on the lower surface 73 of batten 61.Like this, when the back of central part 65 and batten 61 joins and spike 63 when being knocked in rafter wood 62, central part 65 is promptly pulled to rafter wood 62 gradually, and a reliable clamping force is provided between batten 61 and rafter wood 62.For the spike that prevents relative same link inserts rafter wood 62 and may be with the division of rafter wood with coaxial relation, can make the perpendicular distance between the axis of spike and central part 65 have more different.

Certainly, should see that the above only provides illustrated example of the present invention, apparent to those skilled in the art to this all improvement and modification, and can think all within the main scope and boundary of aforesaid the present invention.
