Description
Technical field
The utility model relates generally to a kind of biconial through-wall bolt casing.
Background technology
During present concrete works pouring construction, there are mainly two types of prick post wall screw casings：One, common column spiral shell through walls
Bolt casing, such column bolt sleeve length through walls are 3-4 meters, and construction site according to demand, manually cuts into 20-40 centimeters, holds
Easily leave the extra material that can not be used.When concrete slab wall column formwork for placing is installed, by will manually meet concrete slab
The common through-wall bolt casing of wall column size requirement carries out reinforcing use, and common through-wall bolt casing both ends need to add end cap.
It is easily damaged in casting concrete because common through-wall bolt casing strength is low after the completion of pouring, lead to common through-wall bolt set
Pipe can not be extracted.And both ends end cap need to be rejected manually, end cap can not recycle, and increase labour cost and material cost in this way；
Two, single taper through-wall bolt casing needs, with end cap, after the completion of concrete board wall pours, to need to make list using specific purpose tool
Taper through-wall bolt casing is detached, design in this way makes through-wall bolt casing cost by larger impact force with concrete wall
It is high, can recycle, but dismantle inconvenient, and assign the larger impact force of single taper through-wall bolt casing and make itself and concrete
The mode of wall separation causes single taper through-wall bolt Service Life of Casing shorter.
Therefore, it is necessary to design a kind of Novel bolt casing, have it is reusable, be not required to reprocessing can be used directly, just
In dismounting, service life is long the characteristics of, so as to reduce labour cost and material cost.

The good cement that makes is separated with through-wall bolt, and can guarantee that first sleeve rotates rotation with the second casing under the assistance of electric tool
Go out.
Preferably, the first dismounting bayonet and the second dismounting bayonet are interior hexagonal groove.
It is using the advantageous effect of above-mentioned technical proposal：First dismounting bayonet and the second dismounting bayonet are interior hexagonal groove,
Convenient for being used cooperatively with existing extracting tool, ensure that extracting tool can easily make biconial through-wall bolt casing and wall
Separation.
Preferably, the first sleeve, the taper of the second casing are identical, and taper is 3 ° to 8 °.
It is using the advantageous effect of above-mentioned technical proposal：First sleeve, the taper of the second casing are identical, taper be 3 ° extremely
8 °, the area smaller that biconial through-wall bolt casing can be made to be contacted with wall makes biconial through-wall bolt casing so as to reduce
Required power is detached with wall, the abrasion of biconial through-wall bolt casing is reduced, increases its service life.
Preferably, the biconial through-wall bolt casing length range is in 20cm to 30cm.
It is using the advantageous effect of above-mentioned technical proposal：Biconial through-wall bolt casing length range in 20cm to 30cm,
While disclosure satisfy that the requirement that existing wall pours, quotient's molding batch production easy to produce.
Preferably, the lower face of the first sleeve is both provided with waterproof end cap, institute with the lower face of the second casing
Waterproof end cap is stated to be integrally formed with first sleeve or the second casing.
It is using the advantageous effect of above-mentioned technical proposal：Waterproof end cap is integrally formed with casing, reduces the purchase of waterproof end cap
Expense is bought, and easy to use.During pouring, biconial through-wall bolt casing has one end of waterproof end cap and the wallboard tight
It leans on, ensures that internal cement will not be excessive.
