Abstract
The utility model relates to an expansion bolt, which comprises expansion nails and an expansion tube, wherein, the tail end of the expansion tube is connected with expansion fins with the identical external diameter with that of the expansion tube in an integrated way. Holes for the expansion nails are penetrated from the head end of the expansion tube to the head end of the expansion fins, expansion joints arranged between more than two paratactic expansion fins are communicated with the expansion nails, and a fastening thread is arranged on the surface of the external diameter of the head end of the expansion tube. The using method of the utility model is that the expansion nails are released from the holes for the expansion nails arranged on the head end of the expansion tube, the nail parts of the expansion nails driven into the expansion tube expand the expansion fins, and the purpose of fastening the expansion tube is realized. Compared with the traditional expansion tube, the utility model has convenient use.
Description
The utility model belongs to common engineering, the device that fastening or fixed component or machine parts are used, for example fixing bolt.
EXPANSION ANCHOR BOLTS is widely used in movable part is fixed in the engineering of fixed buildings.The EXPANSION ANCHOR BOLTS of using comprises an expand tube and runs through the interior bloated nail of expand tube at present, and expand tube tail end one is connected with the bloated wing of same outer diameter as, at the nail head end that expands binding thread is arranged, and the nail tail end that expands is a wedge end seat, and expand tube tail end inner chamber cooperates with bloated nail wedge end seat.On fixed buildings, punch earlier during use according to the expand tube external diameter, after the nail that will expand penetrates from the expand tube tail end, again expand tube is imbedded in the hole, the binding thread of following closely that expands exposes outside the hole, connecting hole on the member to be fixed passes to expand and follows closely, and screws the nail that expands with nut then, forces outside the nail that expands to move, the bloated wing of expansion is fastened on member on the building.To put expand tube earlier by the punching of expand tube external diameter when the shortcoming that this EXPANSION ANCHOR BOLTS exists is to use, refill member, and then spin nut.And before punching, member will be set earlier, on building, mark punch position.Member bring up to move down pretty troublesome.
The purpose of this utility model is to make it have effect easy to use by the structure that improves EXPANSION ANCHOR BOLTS.
Content of the present utility model: comprise expand nail, expand tube, the expand tube tail end is connected with the bloated wing of same outer diameter as, it is characterized in that expand tube head end to the wing head end that expands has the bloated nail hole of running through, expansion joint (E.J.) between the plural bloated wing arranged side by side is communicated with the nail hole of expanding, and on the outer diametric plane of expand tube head end binding thread is arranged.The wing external diameter surface that expands has annular corrugated.Annular corrugated crest can tilt to be reversed acanthoid to the bolt head end.The nail that expands directly can have the location arris on the body.
The utility model has the advantages that easy to use.Because binding thread is on expand tube, will the member location after directly punching on building, dress expand tube, spin nut being put the nail that expands then in expand tube, the nail that expands is driven in expand tube just once finish the fastening location construction of member.Remove member from and bring up to the trouble that moves down.
Embodiment of the present utility model as shown in drawings.
Accompanying drawing is the whole decomposing schematic representation of the utility model EXPANSION ANCHOR BOLTS.
Number in the figure is respectively:
1. the nail that expands, 11. arris, 12. nail points, 2. nut, 3. packing ring, 4. expand tube, 41. expand tube binding threads, the 42. nail holes of expanding, 43. wings that expand, 431. reversed acanthoid ring grains, the 432. wing taper holes that expand, the 433. wings seams that expand.
In conjunction with the accompanying drawings the utility model is specified:
On these routine expand tube 4 head end external diameters binding thread 41 is arranged, cooperate with tightening nut 2, expand tube 4 central authorities have the nail of expanding hole 42 to cooperate with the nail 1 that expands.Arris 11 makes the nail 1 that expands remain on the central position in nail hole 42.Nail point 12 cooperates with taper hole 432 under nature.Expand tube tail end one is not connecting bloated wing 43.On the bloated wing 43 tail end external diameters annular ripple is arranged, annular ripple can be to be reversed acanthoid ring grain 431.The bloated wing 43 of this routine expand tube is divided into four by the bloated wing seam 433 of criss-crossing, and the wing seam 433 that expands communicates with nail hole 42.
The using method of this routine EXPANSION ANCHOR BOLTS is earlier member to be placed on the fixed position, with drill bit is punched in the building foundation in the connection place, can directly adorn EXPANSION ANCHOR BOLTS without mobile member in the hole.Can earlier nut be spun on the expand tube head end before the dress bolt, bloated nail is put in the hole of expanding.After in the expand tube load hole, knock the nail that expands, make the nail aperture of the head of a nail and expand tube head end even up just end of operation.This moment, the taper hole at bloated wing head end place was subjected to bloated nail extruding, and bloated wing expands outwardly, and the deep becomes interference fit with building in the hole, building foundation, and member firmly is fixedly connected on building.The effect of the annular ripple on the bloated wing is to make the wing that expands be embedded among the building foundation strong fix.
Can manufacture the EXPANSION ANCHOR BOLTS of all size according to this programme, replace all kinds of EXPANSION ANCHOR BOLTS of using at present.
Claims (4)
1, a kind of EXPANSION ANCHOR BOLTS, comprise expand nail, expand tube, the expand tube tail end is connected with the bloated wing of same outer diameter as, it is characterized in that expand tube head end to the wing head end that expands has the bloated nail hole of running through, expansion joint (E.J.) between the plural bloated wing arranged side by side is communicated with the nail hole of expanding, and on the outer diametric plane of expand tube head end binding thread is arranged.
2, EXPANSION ANCHOR BOLTS according to claim 1, the wing external diameter surface that it is characterized in that expanding has annular corrugated.
3,, it is characterized in that annular corrugated crest tiltedly is reversed acanthoid to bolt head end song according to the described EXPANSION ANCHOR BOLTS of claim 2.
4, according to claim 1,2,3,4 described EXPANSION ANCHOR BOLTS have the location arris on the nail footpath body that it is characterized in that expanding.
