Description
Technical field
The present invention relates to tunnel duct piece production technical fields, and in particular to a kind of novel tunnel lining segment mold.
Background technique
Shield construction is subway construction most safely and effectively construction method, is slowly used by unit in charge of construction.Shield
One component of construction most critical is tunnel lining segment；With the fast development of shield construction, the need of tunnel lining segment
Ask growing；Main concrete prefabricated element of the tunnel lining segment as subway shield tunnel construction, production technology is more complex,
It is required that also increasingly severe.Wherein, the casting per a piece of shield duct piece is completed mainly by means of segment die.
The production of existing tunnel duct piece mold mainly uses three kinds of concrete vibrating modes: artificial insertion is vibrated, monoblock type is vibrated and
Adhesion type vibrates, wherein artificial insertion is vibrated, time of vibration is long, and production efficiency is low, large labor intensity；Oscillating mass human factor
Height, is easy fluctuation, and die size modulability is poor；Monoblock type is vibrated, and diebolt quantity is more, and structure is comparatively laborious, manipulation strength
Greatly, time-consuming, arduously, die size modulability is poor；Adhesion type vibrates using flexible structure, and structure is simpler, but mould structure is not
Stablize, after opening and closing is closed, dimensional accuracy changes greatly, and bottom rubber strip is easily lost, and section of jurisdiction molding effect is poor at rubber contact.
In addition existing adhesion type vibrates mold side form, end mould and bed die using bridging type steel chamfer contact mode, causes
Mould inside is not easy to construction personnel's cleaning there are dead end of cleanning, and vibrating effect is poor.
Therefore, developing the tunnel lining segment mold that a kind of structural stability is good, adhesion type with high accuracy vibrates extremely has
It is necessary.
Summary of the invention
The purpose of the present invention is to provide a kind of novel tunnel lining segment mold, the mold accurate positioning, stable structure,
Precision is higher, and dead end of cleanning is not present, can vibrate suitable for adhesion type, improves product quality.
To achieve the goals above, the technical scheme is that
A kind of novel tunnel lining segment mold including bed die, is symmetricly set on the end mould of bed die two sides and symmetrically sets
The side form at the top of bed die is set, the side form bottom end and end mould bottom end are connect by hinge means with the bed die, the side form
With end mould by adjustable conical positioning device and the bottom mould postioning, the side form passes through taper positioning device and the end mould
Positioning, the side form is by locking device and the bed die and holds mold lock tight, between the side form and bed die and the end mould and
Mold open device is provided between bed die.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention connects side form, end mould and bed die by hinge means, facilitates switching action；
2, the present invention is that side form, end mould and bed die are positioned by adjustable conical positioning device, can be by adjustable
Formula taper positioning device is accurately sized, while pyramidal structure stability is high, not easily shifted, guarantees overall structure stability；
3, the present invention is that side form and end mould are positioned by taper positioning device, and multiple positioning guarantees folding precision, knot
Structure is stablized；
4, the present invention carries out switching action by mold open device, is convenient for fast demoulding open-close module, while also having
Help guarantee mould and die accuracy, dimensional accuracy after opening and closing for a long time is avoided to change.
Further improvement of the present invention scheme is as follows:
Further, the hinge means includes hinge axis, hinge shaft sleeve and support base, the support base and the bed die
Fixed, the hinge axis is arranged on the support base, and the hinge shaft sleeve is set on the hinge axis, and hinge shaft sleeve with
The side form or end mould are fixed.
By using above scheme, side form or end mould around hinge axis rotation complete mould open/close operation, guarantee mold essence
Degree.
Further, the adjustable conical positioning device includes the first positioning pin that head is taper, and described first is fixed
Position pin outer peripheral surface is equipped with screw thread, and first positioning pin is externally provided with and the matched adjusting nut of the screw thread, the adjusting nut
It is fixed on inside the side form or end mould, first positioning pin passes through the adjusting nut towards the bed die, the bed die
It is equipped with and the first positioning matched first set pin sleeve of pin head part.
By using above scheme, according to actual size situation, by bolt arrangement adjust the advance and retreat of the first positioning pin from
And guaranteeing that the conical nose of the first positioning pin is bonded closely with the first set pin sleeve, side form, end mould and bottom mould postioning are accurate, in addition
The head steady of taper is higher, not easily shifted, helps to improve positioning accuracy.
Further, the taper positioning device includes the second positioning pin that head is taper, and second positioning pin is solid
It is scheduled on the side form, the end mould is equipped with and the second positioning matched second set pin sleeve of pin head part.
