Abstract
The utility model is related to preset staircase boards production fields; more particularly to a kind of pre-buried processing unit of stair; including built-in fitting and with the matched demoulding mechanism of built-in fitting; built-in fitting and demoulding mechanism in this example match; pulling capacity is generated by screw-thread fit to extract built-in fitting; substitute traditional drawing it is hard tear open, direct drawing mode, the unfilled corner situation prevented reduces unnecessary cost expenditure.
Description
Technical field
The present invention relates to preset staircase boards production field more particularly to a kind of pre-buried processing units of stair.
Background technology
In the production process of preset staircase boards, the pre-buried built-in fitting in mold, completion is needed to pour and solidify before pouring
Built-in fitting is taken out afterwards, pre-buried position forms embedded hole, is positioned convenient for the subsequent installation of preset staircase boards.
Traditional built-in fitting is that cylinder is taken out built-in fitting by the direct drawing to built-in fitting when demoulding, due to
Close to the corner of preset staircase boards, traditional direct drawing mode is easier to cause the damage of preset staircase boards, causes at pre-buried position
The case where preset staircase boards unfilled corner, and needs to handle again once this occurs at the unfilled corner of preset staircase boards, causes to give birth to
Producing efficiency reduces, and improves production cost.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, a kind of pre-buried place of stair is provided
Manage device.
The present invention is to be achieved by the following technical programs：
A kind of pre-buried processing unit of stair, including built-in fitting and with the matched demoulding mechanism of built-in fitting, wherein
It is provided with inner groovy in the middle part of the built-in fitting, is provided with the first hold-doun nut in the middle part of the inner groovy, the built-in fitting exists
It is provided with the relief hole coaxial with hold-doun nut on the downside of inner groovy；
The demoulding mechanism includes demoulding supporting rack, the second hold-doun nut for being fixed at the top of demoulding supporting rack and with second
The matched stripper bolt of hold-doun nut.
The threaded shank length of the stripper bolt is longer than distance between demoulding supporting rack top and the first hold-doun nut.
The demoulding supporting rack top plate that includes support pipe and be welded at the top of support pipe, with the in the middle part of the top plate
Two hold-doun nuts are welded and fixed.
The support pipe bottom is welded with supporting table along its ring week.
The built-in fitting is circular cone shape.
The beneficial effects of the invention are as follows：
Built-in fitting and demoulding mechanism in this example match, and generating pulling capacity by screw-thread fit extracts built-in fitting, replaces
Generation traditional drawing it is hard tear open, direct drawing mode, the unfilled corner situation prevented reduces unnecessary cost expenditure.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is a kind of example structure schematic diagram of the present invention.
In figure：1. built-in fitting, 2. inner groovies, 3. first hold-doun nuts, 4. relief holes, 5. demoulding supporting racks, 6. second is solid
Determine nut, 7. stripper bolts, 8. support pipes, 9. top plates, 10. supporting tables.
Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, below in conjunction with the accompanying drawings and most
The present invention is described in further detail for good embodiment.
As shown, the present invention include built-in fitting 1 and with the matched demoulding mechanism of built-in fitting, wherein
It is provided with inner groovy 2 in the middle part of the built-in fitting, the first hold-doun nut 3, the built-in fitting are provided in the middle part of the inner groovy
The relief hole 4 coaxial with hold-doun nut is provided on the downside of inner groovy；
The demoulding mechanism includes demoulding supporting rack 5, the second hold-doun nut 6 for being fixed at the top of demoulding supporting rack and with the
The threaded shank length of the matched stripper bolt 7 of two hold-doun nuts, the stripper bolt is longer than demoulding supporting rack top and first
Distance between hold-doun nut.
The first hold-doun nut is fixed in built-in fitting, the relief hole that built-in fitting is provided on the downside of the first hold-doun nut is convenient for demoulding
The entrance of the threaded shank of bolt；
Stripper bolt is known stay bolt comprising threaded shank and the head being connect with threaded shank.
When demoulding, demoulding support is placed on above built-in fitting so that the threaded shank of stripper bolt is along the second hold-doun nut
It screws in, and the threaded shank of stripper bolt is made to screw in the first hold-doun nut, continue the head of rotating stripping demoulding bolt, spiral shell must be demoulded
It is close to demould at the top of supporting rack at the top of the head of bolt and supporting rack, with the head for continuing rotating stripping demoulding bolt, stripper bolt exists
The supporting role of demoulding supporting rack does not continue to be screwed down, and the threaded shank of stripper bolt is matched with the first hold-doun nut,
As threaded shank rotates, the first hold-doun nut is by pulling capacity upward caused by threaded shank rotation, as drawing dynamics adds
Greatly, until the first hold-doun nut is moved, and then entire built-in fitting is driven to be extracted from preset staircase boards.
Preferably, the demoulding supporting rack includes support pipe 8 and the top plate being welded at the top of support pipe 9, the top
Be welded and fixed with the second hold-doun nut in the middle part of plate, and be provided on the downside of the second hold-doun nut for stripper bolt by through hole.
Preferably, the support pipe bottom is along being welded with supporting table 10 its ring week, supporting table and preset staircase boards
Concrete surface contact, there is larger contact surface to connect so that demoulding supporting rack place it is firm, and when demoulding supporting rack by
When pressure, the evenly dispersed pressure of supporting table prevents preset stair plate surface fail in compression in concrete surface.
Preferably, the built-in fitting is circular cone shape, convenient for demoulding.
Built-in fitting and demoulding mechanism in this example match, and generating pulling capacity by screw-thread fit extracts built-in fitting, replaces
Generation traditional drawing it is hard tear open, direct drawing mode, the unfilled corner situation prevented reduces unnecessary cost expenditure.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
