Abstract

Self -supporting rivet nail. The rivet nail comprises nail pole, cover ring sum tubular metal resonator. The nail pole is pin fin, polished rod section, cone section, thin polished rod section, annular section in the past, breaks groove and afterbody kerve section to the back. The lantern ring and the locking of annular section, the metal pipe box is in thin polished rod section periphery. The metal pipe box has the nail pole tail end of tubular metal resonator to pass by the connecting piece mounting hole, loads onto the lantern ring, and the afterbody inserts the riveting ware and presss from both sides in the lamella, starting the riveting ware, being used down by the riveting masterpiece, the extrusion metal pipe makes the front end warp, extrusion cone section, formation tubular metal resonator bell, the nail pole moves backward, the gun barrel antedisplacement, and the whole lockings of the lantern ring are outside the annular section, and it is fixed that the tubular metal resonator bell warp the extrusion, break the groove deal with and open, accomplish and connect. The tubular metal resonator with warp the joint strength that has guaranteed support piece and to by the unsettled planar protection of connecting piece, locking structure is out of shape in the riveting of cover ring sum annular section, guarantees anticipated clamp force. Realization grow up plane joint strength height, surfacing, difficult not hard up. The connection that is applicable to cavity sheet metal, channel -section steel, flange structure etc. Is fixed.

Description

Self-supporting pulling rivet

(1) technical field:

The utility model relates to a kind of design of pulling rivet, making and mounting technique.Be mainly used in the connection of the planes of growing up such as the channel-section steel at the place such as corners of building, beam extension, hollow book plate, flange arrangement.Belong to the structure class (E04B) of building.

(2) background technique:

In engineering construction, at places such as corners of building, beam extensions, the linkage structure of the planes of growing up such as existing connected piece channel-section steel structural member, hollow book plate, is shown in Fig. 8-Figure 10.

The first existing plane linkage structure of growing up is shown in Fig. 8 (installing).With longer common pulling rivet, connected piece channel-section steel structural member 6, upper and lower two pieces of hollow thin plates 7,5 are once connected and fixed.Common pulling rivet, is made up of nail bar 1n and collar 2n, nail bar by ailhead 1.1n, polished rod 1.2n, annular groove section 1.3n lock with collar 2n, break groove 1.4n (rivet front to follow closely on bar afterbody kerve section in addition).Thisly be connected and fixed structure there are the following problems: 1) owing to growing up in the surface of upper and lower two hollow thin plates very much, surface plate is also thinner, anti-bending strength and compression resistance more weak, so after being subject to riveting pressure, make channel-section steel top and bottom and upper and lower hollow thin plate all produce bending deflection.Dotted line 6b in Fig. 8 is shown in by bending line, causes damaging or destroying these planes, do not reach expected effect.2) see Fig. 8, when project organization strength deficiency, after having riveted, channel-section steel two back gauge can be reduced into Hb from installation requirement height H, simultaneously because the situation that clamping force decays appears in two interplanars, causes product to loosen.

The existing plane linkage structure of growing up of the second is shown in Fig. 9, Figure 10 (installing).Be suitable for the unrestricted occasion in riveted joint space.Shorter common pulling rivet W is adopted between the upper and lower both sides of channel-section steel and upper and lower hollow thin plate _crivet on both sides respectively.There are the following problems for this linkage structure: 1) add riveted joint time and riveted joint cost.2) can not cause by the distortion of riveting parts because of rivet force in riveting process, because upper and lower channel-section steel structure is middle without any link or support, although therefore single plane is not destroyed, but channel-section steel structural entity still easily produces distortion.The height of channel-section steel structural member opening edge is easily caused to be reduced into Hc (see Fig. 9) by H or to expand for H when exposed to external forces _d(see Figure 10).Hook to be shown in Fig. 9 in dotted line 6c and Figure 10 shown in dotted line 6d.

(3) summary of the invention:

The self-supporting pulling rivet that the utility model provides, its objective is and solve the place such as corners of building, beam extension, the plane of growing up such as channel-section steel, hollow book plate adopts existing common pulling rivet to connect, and causes connected piece profile and highly produces distortion, damage or destroy being connected plane; The problems such as clamping force decays, and product is loosening.

Technological scheme is as follows:

Self-supporting pulling rivet, comprising: be enclosed within nail bar outside the flange plate being placed in front and rear sleeve composition the collar; Nail bar be ailhead 1.1 foremost, follow closely bar last three sections be extrude with the collar lock annular groove section, break groove and afterbody kerve section; It is characterized in that:

1) following three sections are had between ailhead 1.1 and annular groove section 1.5 from front to back: polished rod section 1.2, cone segments 1.3, thin polished rod section 1.4; Thin polished rod section outer diameter D _1.4be not less than annular groove section nominal diameter D _1.5.2) have metal tube 3 at thin polished rod section 1.4 periphery cover, metal tube and thin polished rod intersegmental for being slidably matched, metal tube length L ₃equal with by distance H in riveting parts.Thin polished rod segment length L _1.4generally determine apart from H by rivet model with by riveting parts.Cone segments length L _1.3generally consistent with the length that the metal tube front end required is out of shape and opening angle with tapering.Metal tube wall thickness is generally chosen by by riveting parts actual demand.

The utility model beneficial effect:

1) on self-supporting pulling rivet nail bar, metal tube is set with as supporting element outside thin polished rod section; And in polished rod section with thin polished rod is intersegmental establishes cone segments, by the axial action extrusion metal pipe of rivet force, metal tube front end is out of shape and forms taper mouth 3a along cone segments surface, realize the plastic deformation of supporting element metal tube.Cone segments plays leading role to metal tube distortion extension.Thus the novel pulling rivet adopting this special construction to design and rivet deformation mode, ensure that the join strength of supporting element, stability.It can protect the unsettled plane of connected piece, can also provide certain supporting effect, make its unsettled plane surface smooth indeformable between two planes be connected for it.2) this novel pulling rivet and riveting method remain the collar of common pulling rivet and the intersegmental rivet deformation radial direction locking of annular groove, axial compacting structure.Therefore can not only to reach the unsettled plane of overfill protection indeformable for the utility model, and can ensure the clamping force of expection.Achieve on the whole and grow up that plane join strength is high, surfacing, not easily the effect such as to loosen.Be applicable to the connection of the plane institution movements of growing up such as hollow thin plate, channel-section steel structure, flange arrangement.
