The specific embodiment
Understand for technical characterictic of the present invention, purpose and effect being had more clearly, now contrast description of drawings the specific embodiment of the present invention.Wherein, identical parts adopt identical label.
Fig. 3-5 shows is mould according to a kind of U of being used for type concrete sheet-piling of a specific embodiment of the present invention, as shown in the figure, this mould can be used for making the U type concrete sheet-piling shown in Fig. 1-2, that is to say, the cross section of U-shaped in general made and had by this sheet pile by concrete.The diagram mould comprises: 10, two of inverted U-shaped lower part steel mould can open, closed upper part steel moulds 20,20 ' and, upper part steel moulds 20,20 ' closure is afterwards and formed an inner chamber 30 with the form fit of sheet pile shown in Fig. 1-2 between the lower part steel mould 10; Two upper part steel moulds 20,20 ' be hinged on by a rotating shaft 40,40 ' respectively both sides of lower part steel mould 10.For preventing spillage, upper part steel moulds 10 and lower part steel mould 20,20 ' interconnective part is provided with sliver or rubber strip (not shown).
In addition, the diagram mould can further include a stay-bolt 50, when two upper part steel moulds 20, after 20 ' closure, stay-bolt 50 can with two upper part steel moulds 20,20 ' top link together so that two upper part steel moulds 20,20 ' fixed-site, and the shape of keeping inner chamber 30 can arbitrarily not change.
During use, can by manually or pneumatic cylinder or hydraulic jack (below will further specify) to this make two upper part steel moulds 20,20 ' closures, afterwards can by stay-bolt 50 with two upper part steel moulds 20,20 ' top link together.Certain mark or scale (not shown) can be set on the stay-bolt 50, when stay-bolt 50 two upper part steel moulds 20,20 ' between length reach set to require after, two upper part steel moulds 20,20 ' the position just determined to get off, the shape of inner chamber 30 just can arbitrarily not change yet.
Afterwards, can pour the concrete that mixes in inner chamber 30 from the breach after two upper part steel moulds 20,20 ' closure, the concrete surface on breach top is by artificial or alternate manner is floating.Treat after the concrete setting in the inner chamber 30, can by manually or pneumatic cylinder or hydraulic jack (below will further specify) to this make two upper part steel moulds 20,20 ' to open, the promptly first one-step forming of the U-shaped concrete sheet-piling A in the mould can hang away placement with instruments such as cranes.
Shown also among Fig. 3-5 that two drive two upper part steel moulds 20,20 ' around rotating shaft 40,40 ' opened, closed pneumatic cylinder or hydraulic jack 60,60 '.That is to say, these two pneumatic cylinder or hydraulic jack 60,60 ' can be used for replacing manually opening, closed upper part steel moulds 20,20 '.Certainly, those skilled in the art are to be understood that, this two pneumatic cylinder or hydraulic jack 60,60 ' can be by control cylinder air pressure or hydraulic jack the mode of oil pressure size control automatically, control two upper part steel moulds 20 with this, 20 ' the position, and the shape of keeping inner chamber 30 can arbitrarily not change.In this case, stay-bolt 50 can omit need not, certainly,, also can under the situation of using pneumatic cylinder or hydraulic jack 60,60 ', use stay-bolt 50 simultaneously for accurate positioning.
Among Fig. 3-5 as seen, lower part steel mould 10 and pneumatic cylinder or hydraulic jack 60,60 ' are arranged on the base 80, from the side view of Fig. 5 as seen, the channel-section steel that these bases 80 are actually by a plurality of cross-brace lower part steel mould 10 and pneumatic cylinder or hydraulic jack 60,60 ' constitutes.Certainly, it will be appreciated by those skilled in the art that lower part steel mould 10 and pneumatic cylinder or hydraulic jack 60,60 ' also can directly install or be arranged on the smooth ground, for example be installed on the cement flooring by bolt.Need to prove that length direction of the present invention is the direction perpendicular to paper shown in Fig. 3-4, described laterally is direction perpendicular to described length direction.
In addition, in a specific embodiment of the present invention, mould of the present invention can be made U-shaped concrete sheet-piling A by the mode of vibration moulding, as shown in Figure 3-4, is provided with a plurality of electromagnetic shakers 70 in its underpart along lower part steel mould 10 length directions.Electromagnetic shaker 70 can be drilled the die length direction by the operating distance of required vibration force and evenly be arranged.
From Fig. 5 as seen, entire die can freely be set its length according to the length of the U-shaped concrete sheet-piling A that makes, therefore, in order to guarantee that entire die is unlikely to distortion, length direction along mould can be provided with a plurality of pneumatic cylinder or hydraulic jack 60,60 ', these pneumatic cylinder or hydraulic jack 60,60 ' can be arranged on the channel-section steel that constitutes base 80 just.
In order to guarantee that lower part steel mould 10 is unlikely to distortion, be provided with a plurality of dividing plates 90 in its underpart along lower part steel mould 10 length directions, dividing plate 90 is provided with at least one steam-cured hole 100 that can supply steam to pass through.That is to say that this mould of the present invention can be in the process of vibrating forming, simultaneously by at steam-cured hole 100 logical steam the U-shaped concrete sheet-piling being carried out the maintenance operation.In addition, the stretch-draw of sheet pile, vibration and maintenance can be carried out in mould.
The heating and cooling surface maintenance example of a product of the present invention, concrete grammar is as follows: with the surface of product contact stake of the present invention, left standstill 17 hours, programming rate is 25 ℃/h, constant temperature phase temperature range is 95 ℃, constant temperature time 24 hours, and cooling rate is 20 ℃/h; Wherein,
The preferred by weight proportioning of described surface conditioning agent dry weight component is: 0.008 part of cellulose ether, 0.02 part of concentrated hydrochloric acid, 0.08 part in methyl hydroxyethylcellulose ether, 5 parts of sodium alginates, 12 parts of DBSAs, 5 parts of sulfo-succinic acids, 20 parts in graphite adds 2 times of mixing and stirring of water by mixed weight portion.
The mould of the above-mentioned U of being used for type concrete sheet-piling provided by the invention is a kind of mould of special use, to be used for the mentioned U type concrete sheet-piling of production background technology part.
The above only is the schematic specific embodiment of the present invention, is not in order to limit scope of the present invention.Any those skilled in the art, equivalent variations, the modification of being done under the prerequisite that does not break away from design of the present invention and principle and combining all should belong to the scope of protection of the invention.
