Fixing screws are fixed with fixed flitch, and two U-shaped card plates are fastened on respectively on two fixed flitches, the fixed flitch and U-shaped
The side of snap-gauge offers bolt hole, connection bolt is inserted in bolt hole, connection bolt is by U-shaped card plate and fixed wood
It is fixed between side.
Preferably, the outer diameter of the protection steel pipe is 48.3mm, wall thickness 3.5mm.
Preferably, the curved opening is cut into the port of width 20mm by 90 degree, and the length of curved opening is
The half of steel pipe circumference.
Preferably, the length that the slotting wall screw is located at outside main structure is all larger than the outer diameter of protection steel pipe, the slotting wall
The positional distance of anchor bolt, which faces, is not less than 250mm at hole.
Compared with prior art, the utility model has the beneficial effects that the utility model structure setting is reasonable, the hole is anti-
Protection unit is steel pipe both ends will to be protected to be cut into curved opening, and two are symmetrically fixed in the main structure for facing side hole both sides and is inserted
Then wall screw and two fixed flitches will protect two curved openings on steel pipe to be directly clamped among two slotting joist anchors from top to bottom
It on bolt, protects the two U-shaped card plates welded on the downside of steel pipe that can be stuck on two fixed flitches at this time, then passes through connection spiral shell
U-shaped card plate and fixed flitch locking, protection steel pipe can be directly taken out connection bolt, above watch out for shield steel by bolt when removing
Pipe can be completed, and after protecting steel pipe to remove, without cutting slotting wall screw, can directly hammer within the walls, in the mistake of plastering construction
In journey that its is hidden, fixed flitch can also be removed directly from wall, and the upright bar for avoiding traditional form is all to later period ground
The influence of working procedure, and reduce the cutting of expansion bolt and the destruction of floor construction.
