The constant head tank is the chute. The mould that to make like the setting element of shape of complying with one's wishes has been designed to can easily take out the setting element having made, can not damage the setting element.
Description
Technical field
The utility model belongs to technical field of building construction, is applied to the manufacture of reinforced concrete protection layer keeper, specifically a kind of moulding form of reinforced concrete protection layer keeper.
Background technology
At present, for the location of reinforcement cover corner, what between reinforcing bar and template, placement had certain specification is the conventional means that reinforcement location is fixed in construction by current China with the cushion block of shape, the cushion block of these rules i.e. so-called keeper.Traditional keeper mainly contains mortar pad and plastic cushion two kinds.
The making of mortar pad is easily by the impact of place, environment etc.In mortar field fabrication process, engineering actual progress and target advance easily produce deviation, and cushion block standard thickness differs greatly, and its quality does not reach the requirement of site operation.In addition cushion block is little, not easily colligation, and workman does not often want to take the trouble and unconsciously to put into, during envelope template due to colligation loosely cushion block can come off and off normal, more likely can be crushed.When operation of carrying out vibrating, therefore major part cushion block also can come off and be shifted.
Along with the change of design specifications, one is that shockproof requirements is high, and two is that more than four layers, residential houses prohibits the use porous plate, all change reinforced concrete cast-in-situ superstructure into, therefore, have higher requirement to steel concrete quality requirement, traditional mortar pad obviously can not adapt to.
Therefore consider from economical and use, a lot of people contemplates again this material of plastics.Derived a lot of different types of plastic cushion thereupon.As C shape, H-shaped reinforced concrete protection layer keeper, macromolecular material is adopted to gather the extruded positioning ring for reinforced concrete protective layer etc. of the third ethene.
Although plastic cushion avoids the drawback of mortar pad to a certain extent, but create a new problem, be exactly because of plastics and structure concrete material different in kind, particularly coefficient of thermal expansion and contraction is inconsistent, thus cause using plastic cushion place to have crack to produce, make water or steam very easily enter thus cause reinforcement corrosion.Simultaneously plastic cushion also cannot accurately be fixed, and all exists because the phenomenon that the vibration of smashing generation makes reinforcing bar come off is watered in construction, thus cause reinforcement cover not reach designing requirement during onsite application.
In addition, market also has the reinforcing cage of a kind of garden type guiding topping keeper.Main attack reinforcing bar, secondary muscle also have garden type guiding topping keeper in the design scheme of inner part.Main muscle colligation composition vertical with secondary muscle finer wire reinforcing cage during use, being fixedly connected with of Zai Jiang garden type guiding topping keeper is put in reinforcing cage, can realize the determination of topping.Implement the obvious advantage after this technology and effect is: be first overcome mortar pad and plastic cushion can not occur above-mentioned defect again when building-site uses, the size of topping obtains further accurate.This is not merely improve labor productivity so simply, and what more attract people's attention is the quality turn improving prefabricated units.But what deny not is its obviously loaded down with trivial details, complex process, causes its usability to be had a greatly reduced quality.Add the labour intensity of workman, reduce overall operating efficiency.Therefore in the urgent need to producing a kind of novel keeper, solve the problem, and the mould manufacturing this kind of keeper correspondingly produces.
Utility model content
The utility model provides a kind of moulding form of reinforced concrete protection layer keeper, for the manufacture of the keeper of similar shape as one wishes, solves many defects of existing keeper.
The utility model is achieved through the following technical solutions: a kind of moulding form of reinforced concrete protection layer keeper, comprise backform and bed die, the two ends of described backform and bed die respectively arrange corresponding pin hole, be fixed by installing latch, on described bed die, longitudinally center line offers locating slot symmetrically, described backform offers locating slot in relevant position, the reference column matched with it is provided with in described locating slot, a cavity is offered in the middle of described backform, described cavity comprises the end that middle base portion and both sides are 45 ° of oblique angles, described base portion is isosceles trapezoid, described end is rectangular.Locating slot is skewed slot.
Keeper shape after making is the shape of cavity, and the twice skewed slot with longitudinal centre line symmetry is arranged at the bottom of this keeper, and the shape of this skewed slot and reference column is agreed with mutually.
Further, described backform transversely center line is divided into the first parting and the second parting, and described first parting is arranged on bed die by the latch at two ends, and described second parting is arranged on bed die by the latch at its two ends.
When in knockout course afterwards, we find overall perforate, generally adopt the mode of manual expression to force keeper to deviate from mould, so be easy to keeper is ruptured when extruding by force, the both sides thickness of especially slotting is little, and phenomenon of rupture is more obvious.In order to avoid the component demoulding is that unnecessary damage occurs, therefore backform is designed to a detachable structure, separates from both sides by the first parting and the second parting, taking-up keeper that can be complete.
Further, the thickness of described backform is greater than the thickness of described bed die.Backform is mainly used in building and build shaping, and it is fixing and offer needed for locating slot that bed die plays protection, and therefore backform thickness is according to the thickness of requirement of engineering keeper, and bed die can be suitably thinning.Fully according to engineering characteristic, also avoid waste of material.
The utility model takes above-mentioned corrective measure to carry out, its beneficial effect is remarkable: the utility model devises a kind of mould manufacturing the keeper of the shape that seemingly complies with one's wishes, and having manufactured and can like a cork keeper having been taken out, can not keeper be damaged, ensure high efficiency operation.
