Abstract
The present utility model belongs to the inflating core die technology field and discloses a trapezoid inflating core die. The core die is mainly characterized in that the core die comprises an outer die layer and an inflating inner die, the inflating inner die is formed by arranging a first inflating inner die and a second inflating inner die in an upper and lower way, as for the shape of the first inflating inner die and the second inflating inner die in the inflation state, two ends are half-round, the middle part is rectangular, the length of a middle rectangle of the first inflating inner die is longer than that of a middle rectangle of the second inflating inner die, and a triangular support is arranged between four corners of the outer die layer and the inflating inner die. When pouring a beam body, the inflating inner die is inflated firstly, the outer side surface of the outer die layer is trapezoid under the effect of the inflating inner die and the triangular support, then concrete is poured, gas inside the inflating inner die is let out after the concrete is solidified, and the trapezoid inflating core die is fetched out. the requirement is met by a trapezoid hole, construction is convenient, the core die can be repeatedly used, and demoulding is convenient and rapid.
Description
Technical field
The utility model belongs to the aerated core technical field, relates to concretely trapezoidal aerated core.
Background technology
In fields such as bridge crossbeams, according to the needs of design, in the beam body, reserve trapezoidal hole.Mainly adopt wooden model and punching block when producing this beam body at present, adopt wooden model and punching block to have following defective: can discharge a large amount of heats during concreting, cause the strange heat of steel form incomparable, to build in the good place of ventilating air permeability, and the slit of template existence has the appearance of spillage phenomenon, also have the beam slab of some small-bores, the person operates in can't entering at all, and these all cause certain difficulty to form removal.The manufacture craft very complex of wooden model, waste timber; And fixing relatively more difficult with the demoulding, the number of turnover is also lower.In order to overcome defects, the designer adopts aerated core, but because the aerated core structure, the trapezoidal preformed hole shape of producing does not reach designing requirement.
The utility model content
The technical problem that the utility model solves just provides that a kind of trapezoidal hole meets the requirements, easy construction, reusable, be convenient in demoulding efficiently trapezoidal aerated core.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise external mold layer and inflatable inner mould, described inflatable inner mould is two be arranged above and below the first inflatable inner mould and the second inflatable inner moulds, described the first inflatable inner mould and the second inflatable inner mould two ends that are shaped as under inflated condition are rectangle for semicircle, centre, the length of described the second inflatable inner mould intermediate rectangular of the Length Ratio of described the first inflatable inner mould intermediate rectangular is long, is provided with gusseted between four jiaos on described external mold layer and inflatable inner mould.
Its additional technical feature is:
Be respectively arranged with cylindrical support at the relative side two ends with the second inflatable inner mould of described the first inflatable inner mould;
Described cylindrical support is the 3rd inflatable inner mould and the 4th inflatable inner mould;
Be provided with typing lacing wire up and down at described the first inflatable inner mould and the second inflatable inner mould inboard.
The trapezoidal aerated core that the utility model provides, compare with prior art and to have the following advantages: one, owing to comprise external mold layer and inflatable inner mould, described inflatable inner mould is two be arranged above and below the first inflatable inner mould and the second inflatable inner moulds, described the first inflatable inner mould and the second inflatable inner mould two ends that are shaped as under inflated condition are semicircle, the centre is rectangle, the length of described the second inflatable inner mould intermediate rectangular of the Length Ratio of described the first inflatable inner mould intermediate rectangular is long, between four jiaos on described external mold layer and inflatable inner mould, be provided with gusseted, when needing the casting beams body, at first inflatable inner mould is inflated, under the effect of inflatable inner mould and gusseted, the lateral surface of external mold layer is trapezoidal, this moment casting concrete, after concrete setting, gas in the inflatable inner mould is bled off, take out this trapezoidal aerated core and get final product, trapezoidal hole meets the requirements, easy construction, reusable, be convenient in demoulding quick; They are two years old, owing to be respectively arranged with cylindrical support at the relative side two ends with the second inflatable inner mould of described the first inflatable inner mould, prevented that in casting process concrete pushes the relative side two ends with the second inflatable inner mould of the first inflatable inner mould, cause trapezoidal preformed hole distortion, do not meet designing requirement; Its three because described cylindrical support is the 3rd inflatable inner mould and the 4th inflatable inner mould, use convenient; Its four owing to be provided with typing lacing wire up and down, the first inflatable inner mould and the second inflatable inner mould distortion when having prevented inflation in described the first inflatable inner mould and the second inflatable inner mould inboard.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of trapezoidal aerated core.
The specific embodiment
The structure of the trapezoidal aerated core that the utility model is proposed below in conjunction with accompanying drawing is described further.
As shown in Figure 1, be the cross section structure schematic diagram of trapezoidal aerated core.Its structure comprises external mold layer 1 and inflatable inner mould 2, inflatable inner mould 2 is two be arranged above and below the first inflatable inner mould 3 and the second inflatable inner moulds 4, the first inflatable inner mould 3 and the second inflatable inner mould 4 two ends that are shaped as under inflated condition are rectangle for semicircle, centre, the length of Length Ratio the second inflatable inner mould 4 intermediate rectangular of the intermediate rectangular of the first inflatable inner mould 3 is long, is provided with gusseted 5 between four jiaos of external mold layer 1 and inflatable inner mould 2.When needing the casting beams body, at first with the first inflatable inner mould 3 and 4 inflations of the second inflatable inner mould, under the effect of the first inflatable inner mould 3 and the second inflatable inner mould 4 and gusseted 5, the lateral surface of external mold layer 1 is trapezoidal, this moment casting concrete, wait concrete setting after, the gas in the first inflatable inner mould 3 and the inflation of the second inflatable inner mould 4 is bled off, take out this trapezoidal aerated core and get final product, trapezoidal hole meets the requirements, easy construction, reusable, be convenient in demoulding quick.
Be respectively arranged with cylindrical support 6,7 at the first inflatable inner mould 3 with the second inflatable inner mould 4 relative side two ends, cylindrical support 6,7 can be the 3rd inflatable inner mould 6 and the 4th inflatable inner mould 7, all right other fillers, prevented in casting process, concrete pushes the two ends of the first inflatable inner mould 3 and the second inflatable inner mould 4 relative sides, causes trapezoidal preformed hole distortion, does not meet designing requirement.
Be provided with typing lacing wire 8 up and down at the first inflatable inner mould 3 and the second inflatable inner mould 4 inboards, the first inflatable inner mould 3 and 4 distortion of the second inflatable inner mould when having prevented inflation.
Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the trapezoidal aerated core structure of the utility model, just drops on the scope of the utility model protection.
