Embodiment
See, Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, hollow brick wall EXPANSION ANCHOR BOLTS by: tapered end face 1, inclined-plane 2, conical head 3, expansion sleeve 4, adjutage 5, tapered expansion head 6, expansion sleeve 7, screw rod 8, plain washer 9, spring pad 10, hexagon nut 11 and Baltimore groove 12 part form.
Tapered end face 1, has first end and the second end, is communicated with bottom described tapered end face 1 first end with conical head 3 inner face largest diameter value.Described tapered end face 1 second end top end face is less than conical head 3 inner face largest diameter value 2-5mm, protrudes conical head 3 inner face largest diameter value 2-5mm.Described tapered end face 1 tip edge and conical head 3 inner face largest diameter value bezel 2 cross.
Inclined-plane 2, has first end and the second end, and described inclined-plane 2 first end is tapered end face 1 tip edge, and described inclined-plane 2 second end is conical head 3 inner face largest diameter value edge, and described two edges intersect are inclined-plane 2.It is overall in one is long and the other is short two disjunctor taper shapes for inclined-plane 2 and conical head 3 inner face largest diameter value edges intersect.The technical characteristics that its inclined-plane 2 shows, the interlayer cinclides hole can threaded smoothly into hollow brick wall for tapered end face 1 self can produce positive role.
Conical head 3, has first end and the second end, and described conical head 3 is arranged on bottom screw rod 8 first end.Described conical head 3 first end inner face largest diameter value edge and tapered end face 1 tip edge are that inclined-plane 2 crosses.Face in described conical head 3 second end and connect expansion sleeve 4 first end.Described conical head 3 first end inner face largest diameter value does not exceed 20mm, and longitudinal length does not exceed 20mm.
Expansion sleeve 4, has first end and the second end, is nested with in screw rod 8.Described expansion sleeve 4 first end faces into conical head 3 inner face, and described expansion sleeve 4 second end faces and connects adjutage 5 first end.Described expansion sleeve 4 first end is shaped with the swollen mouth mated with conical head 3 inner face.Described swollen mouth end face is interior corner cut 26.Swollen mouth is shaped with four longitudinal triangular incision 25 of symmetry.Described triangular incision 25 extends within its longitudinal length remains on 25mm to swollen mouth end face by bottom swollen mouth.Bottom triangular incision 25, two limit spacing Extreme breadths at two angles are within 2mm.Bottom triangular incision 25 two limits at two angles extend to swollen mouth end face intersect.Adjacent four swollen page 24 surfaces, triangular incision 25 both sides are light face.Four swollen pages 24 on the swollen mouth of described expansion sleeve 4 start relatively to draw close tapered to the extension of first end end face by the base at two angles bottom triangular incision 25.The end face of the second end of described expansion sleeve 4 is right angle 23.Described expansion sleeve 4 outside diameter is worth equal with conical head 3 inner face largest diameter.The concrete length of described expansion sleeve 4: according to the hollow brick wall hollow brick interlayer wall thickness that will install, lengthens 5-10mm setting in addition again.The hollow brick interlayer wall thickness having two different size of plurality of specifications due to the hollow brick of building hollow brick wall by laying bricks or stones compares two interlayer wall thickness can not be identical.Therefore, there is multiple parameter in the concrete length of described expansion sleeve 4 in hollow brick wall EXPANSION ANCHOR BOLTS is equipped with.
Adjutage 5, has first end and the second end, is nested with in screw rod 8, and described adjutage 5 first end faces and connects expansion sleeve 4 second end, and described adjutage 5 second end faces and connects tapered expansion head 6 first end.Described adjutage 5 external diameter is less than tapered expansion head 6 first end maximum value and expansion sleeve 4 second end external diameter.Described adjutage 5 tube wall 17 thickness is less than expansion sleeve 4 pipe thickness.Described adjutage 5 tube wall 17 inner face presses close to the surface of screw rod 8, and it is subject to external force and pulls and can also slide in screw rod 8.When described adjutage 5 is conflicted at interlayer wall inner face after insert the hollow brick wall hole with expansion sleeve 7 diameter matches with expansion sleeve 4, also has a bit of adjutage 5 meeting temporal persistence outside hollow brick wall hole, at this moment rock temporal persistence outside hollow brick wall hole adjutage 5 with upper part, just can control the trend of tapered end face 1 between hollow brick outer wall with relative hollow section, interlayer wall two sides, just effectively can escort tapered end face 1 and thread smoothly into interlayer cinclides hole.Described adjutage 5 two ends end face is right angle 18.Concrete length between described adjutage two ends: the length setting deducting tapered expansion head 6 according to the hollow brick wall hollow brick outer wall inner face that will install to interlayer wall inner face relative spacing length.Due to the hollow brick of building hollow brick wall by laying bricks or stones have two different size hollow brick outer wall inner face of plurality of specifications compare two relative spacing length to interlayer wall inner face relative spacing length can not be identical.Therefore, in hollow brick wall EXPANSION ANCHOR BOLTS is equipped with, there is multiple parameter in the concrete length between described adjutage 5 two ends.
Tapered expansion head 6, has first end and the second end, and endoporus 16 is unthreaded hole, is nested with in screw rod 8.Described tapered expansion head 6 first end faces and connects adjutage second end.Face the swollen mouth into expansion sleeve 7 first end in described tapered expansion head 6 second end, and can with face the adjutage 5 that connects and face into expansion sleeve 7 move.The external diameter of described tapered expansion head 6 first end is greater than the external diameter of the second end, makes tapered expansion head 6 outer tapered.Described tapered expansion head 6 first end to the second end longitudinal length does not exceed 20mm, and first end maximum outside diameter does not exceed 20mm.Described tapered expansion head 6 second end end face edge and endoporus 16 hole wall edge cross in tip-angled shape.Between described tapered expansion head 6 first end and the second petiolarea, the surface on the symmetrical both sides of cylindrical is respectively provided with a wing 14, the described wing 14 protrudes its surface, the wing 14 protrudes summit peak and does not exceed first end maximum value, and the limit, two, bottom of the wing 14 is protruded by tapered expansion head 6 surface and protrusion summit crosses, and its cross section is triangular in shape.Bottom the wing 14, two limits protrusion tapered expansion head 6 surface spacing Extreme breadths do not exceed 5mm.The wing 14 to the second end longitudinal extension by first end end face edge, is terminated in first end and the second end center or exceedes center, and descending the stopping at of oblique line crosses apart from the second end end face 2-5mm place and tapered expansion head 6 surface, and the wing 14 whole process outwards walks shape in obtuse angle.Its stop surface top to intersection entirety is inclined-plane is del.The described wing 14 oblique line 13 shape is descending is one section of clog-free taper 15 of 2-5mm with the interval of tapered expansion head 6 surperficial intersection to the second end end face.The technique effect that this clog-free taper 15 shows to receive the swollen muzzle of expansion sleeve 7 to enter, and make the four swollen pages 21 volts be inserted on the swollen mouth of expansion sleeve 7 of tapered expansion head 6 inner face 2-5mm, on this section of accessible taper 15 surface, cracking expansion not occur.Described endoporus 16 protrudes tapered expansion head 6 first end external diameter maximum value 2-5mm.Described endoporus 16 is less than tapered expansion head 6 first end maximum value 1.5-2.5mm.The end face maximum value bezel 13 of described endoporus 16 hole wall and first end crosses.The technology shape that this inclined-plane 13 crosses shown, can enter hollow brick wall facing hole for tapered end face 1 and tapered expansion head 7 simultaneously smoothly and interlayer cinclides hole can produce positive role.Described tapered expansion head 6 first end outside diameter maximum value is greater than conical head 3 inner face largest diameter value.
