Description
Technical field
The invention belongs to concrete-pile technical field, more particularly to a kind of mould for producing pre-stressed concrete hollow support pile
Tool.
Background technology
Pre-stressed concrete hollow support pile is a kind of novel high-performance concrete prefabricated element, can be widely used in water conservancy
Construction project, river course waterway regulation works, Municipal Drainage Engineering, the supporting of traffic roadbed, Urban Underground pattern foundation pit supporting structure, Tidal Flat Reclamation
And ocean wave dissipation engineering etc., with market further improved using maturity, product prospect is extremely optimistic.
Pre-stressed concrete hollow support pile is made by mould completing.Patent No.
ZL201620510862.3, entitled " a kind of making mould of centrifugal process concrete hollow support pile " disclose a kind of making mould
Have, the technical scheme of the mould is：Using fourth of the twelve Earthly Branches design under upper tenon, tenon portion is arranged to the top of upper mould, it is corresponding, will
Fourth of the twelve Earthly Branches groove portion is arranged at the bottom of lower mould, and two parallel planes for being used to resist normal section stress of product are located at upper and lower mould respectively
Matched moulds mouthful both sides position.This making mould is that by the tenon mould of formed product at the top of upper mould, fourth of the twelve Earthly Branches channel mould is located at lower mould
Bottom, such setting causes two of finished peg to be used for matched moulds of the parallel plane positioned at upper and lower mould for resisting normal section stress
Mouthful, further, since this two stress surfaces are too big oversize, often there is snap gauge phenomenon in product stripping link during production, it is necessary to logical
Bed die is fixed in ad hoc frock by the mode for crossing machinery locking, and with the stomidium at crane hook block pile body two ends, stake is transferred to by force
Body.Therefore, the drawbacks of this making mould is present is embodied in：
(1) waste time and energy, operation is extremely inconvenient, labor intensity is big, production cost is high, production efficiency is low；
(2) due to snap gauge the problem of, cause pile body card trace, ring crack often occur, knock the quality problems such as damage, have a strong impact on
Product appearance and internal performance；
(3) after the repeated multiple times use of mould, mould damage is serious, metaboly generally occurs, service life is short, repairs into
This height.
The content of the invention
It is an object of the invention to provide a kind of mould for producing pre-stressed concrete hollow support pile, it is intended to solves above-mentioned
The deficiencies in the prior art.
The present invention is achieved in that a kind of mould for producing pre-stressed concrete hollow support pile, and the mould is one
Under master mold, arc tabular in arc tabular master mold, fourth of the twelve Earthly Branches mould bar and the part of tenon mould bar four constitute, the two ends with polygon inner chamber open
The hollow form tubular steel mould of mouth；
It is equipped with the upper master mold Mosaic face, lower master mold Mosaic face recessed with the fourth of the twelve Earthly Branches mould groove and tenon mould of mould axis parallel
Groove；It is provided with the mould groove of the fourth of the twelve Earthly Branches in fourth of the twelve Earthly Branches mould bar, tenon mould groove and is provided with tenon mould bar；
The fourth of the twelve Earthly Branches mould bar is arranged at the inner chamber edge of upper and lower master mold side Mosaic face, and it exposes to the portion in dies cavity face
Divide is in semi-cylindrical or isosceles trapezoid；The upper tenon mould bar of the tenon mould bar point, lower tenon mould bar, are respectively arranged at upper and lower master mold another
The inner chamber edge of side Mosaic face, a semi-circular groove or isosceles trapezoid groove are formed after upper tenon mould bar, the splicing of lower tenon mould bar.
Preferably, the upper master mold, lower master mold be with mutually isostructural semicolumn channel-shaped body, and the upper master mold, under
The mould inside cavity that master mold is spliced is polygonal cylinder；The upper master mold inner chamber top surface is with the lower master mold inner chamber bottom surface
Two symmetrical parallel surfaces, the angle of this two parallel surfaces and respective two neighboring inclined-plane is 120 °.
Preferably, the master mold includes the semi-cylindrical external mold and the semi-cylindrical internal model in external mold of the coaxial heart；Its
In, the external mold includes the spaced external mold running wheel for being located remotely from internal model direction side, and close to the outer of internal model direction side
Die shoe plate, link of boards is indulged between the running wheel and shoe plate by some external mold horizontal bar plates, external mold.
Preferably, the internal model includes the U-shaped profiled sheeting away from external mold direction side, and some internal model horizontal bar plates, internal model
Vertical gusset；
Link of boards is indulged by internal model horizontal bar plate, internal model between the internal model profiled sheeting and external mold shoe plate；The internal model is horizontal
Gusset is provided with the horizontal bar plate through hole of the heart coaxial with internal model.
Compared to the shortcoming and defect of prior art, the invention has the advantages that：
(1) present invention need not use any special frock facility, you can easily realize that pile body is stripped, effectively reduction workman behaviour
Make difficulty, improve production efficiency, reduce cost；
(2) present invention can make mould structure rigidity big by reasonably designing, and service life is long；
