Small taper.The tail end of expansion sleeve is provided with inflation port, and the diameter of inflation port is less than bar in expansion, and the side wall of inflation port is provided with
At least one otch, the otch run through the outer wall and inwall of expansion sleeve, and conehead is inserted in inflation port from front to back, dilating expansion
The otch in hole.
Preferably, the front end of bar is provided with screw terminal in expansion, and the middle part of bar is provided with external screw thread in expansion.Expansion sleeve it is interior
Internal thread is provided with the middle part of wall, bar is rotatably in expansion sleeve in expansion, and the external screw thread of bar and expansion sleeve in expansion
Internal thread engages.Sign Board is provided with is less than screw terminal for the mounting hole that bar activity passes through in expansion, the diameter of mounting hole.
Preferably, six otch are uniformly provided with the side wall of inflation port.
Compared with prior art, the utility model is by expandable nail constant mark board, and expandable nail includes in expansion bar and swollen
It expansion set pipe, need to only be drilled on metope during installation, in expansion sleeve patchhole, then bar be forced in expansion from front to back by external force
Insert in inflation port, the otch in dilating expansion hole, expandable nail is fastened in metope, simple and later maintenance replacing side is installed
Just.
Brief description of the drawings
The utility model is described in detail with reference to embodiment and accompanying drawing, wherein：
Fig. 1 is the fractionation schematic diagram of second embodiment in the utility model；
Fig. 2 is the assembling schematic diagram of second embodiment in the utility model；
Fig. 3 is the installation schematic diagram of second embodiment in the utility model.
Embodiment
As shown in Figures 1 to 3, the utility model proposes Sign Board mounting structure, including：Sign Board 1 and expandable nail, expansion
Nail includes bar 2 and expansion sleeve 3 in expansion, and Sign Board 1 is connected to the front end of bar 2 in expansion, and link position is designed in Sign Board 1
Load-bearing impetus on.Wherein, the tail end of bar 2 is provided with conehead 21 in expansion, what conehead 21 was diametrically gradually reduced from front to back
Taper, the front end of expansion sleeve 3 are provided with connecting hole 31, and the gap of bar 2 coordinates in the diameter of connecting hole 31 and expansion, and conehead 21 is located at
In the connecting hole 31 for expanding sleeve, the tail end of expansion sleeve 3 is provided with inflation port 32, and the diameter of inflation port 32 is less than bar 2 in expansion,
The side wall of inflation port 32 is provided with least one otch 33, such as four or six otch are uniformly distributed in the side wall of inflation port,
The otch 33 runs through the outer wall and inwall of expansion sleeve 3, and inflation port 32 is divided to form expansion piece 34, and conehead 21 is inserted from front to back
Enter in inflation port 32, the otch 33 in dilating expansion hole.
Wherein, the thickness of bar 2 should select according to weight and the institute of Sign Board 1 wall to be mounted of Sign Board 1 in expansion,
Determine in expansion after bar 2, be equipped with corresponding expansion sleeve 3.According to《JGJ/T 271-2012 concrete structure engineerings
Inorganic material post-anchoring technology code》, from meeting《GB/T 22795-2008 concrete intumescent crab-bolt pattern and chi
It is very little》Expandable nail, stress performance see the table below.
The utility model has two embodiments, and in the first embodiment, Sign Board 1 is swollen to be made using metal material
Swollen middle bar 2 is welded on Sign Board 1, and bar 2 is actively set in expansion sleeve 3 in expansion, using boring bar tool in metope during installation
Upper drilling, specification and the expansion sleeve 3 in hole match, gently tap wooden mallet or rubber hammer in Sign Board welding expansion after drilling
The front of bar 2, tap to expansion sleeve 3 and slightly protrude the surface in hole.During percussion, expansion sleeve 3 moves into hole,
The conehead 21 of bar 2 is inserted in inflation port 32 from front to back expand simultaneously in, the otch 33 in gradual dilating expansion hole, makes expansion sleeve
3 are fixed in hole.Whole installation process only needs to drill and beat, and reduces gluing cooling, seamless glue in the prior art
