The utility model discloses a kind of tunnel-liner model and build instrument, comprise base, internal mold and external mold, described external mold center is provided with the outer nib of Tunnel-hole shape, and one end of external mold is arranged on base; Described internal mold is arranged in the outer nib of external mold, and leaves tunnel-liner between outer nib and build groove.The utility model structure is simple, easy to operate, the tunnel-liner model of building out be close to Practical Project, thoroughly solve the problem that the comparatively abstract and students of traditional tunnel teaching is not easy to understand, the tunnel-liner model simultaneously obtained can carry out the higher model test of similarity in a large number.
Description
Technical field
the utility model relates to a kind of teaching mode, particularly relates to a kind of tunnel-liner model and builds instrument.
Background technology
tunnel Engineering is the important subject of of civil engineering, Ge great colleges and universities, scientific research in one's power engineering unit all have teaching and the model experiment of this course, because there is no good tunnel-liner model, therefore traditional tunnel teaching adopts word and illustration, impart knowledge to students comparatively abstract, students is not easy to understand, and traditional tunnel experiment all adopts and distinguishes larger model with actual conditions, larger with Practical Project difference.
Summary of the invention
in order to solve the problems of the technologies described above, the utility model provides simple, the easy-operating tunnel-liner model of a kind of structure and builds instrument, it can solve the problem that teaching comparatively abstract and students in traditional tunnel is not easy to understand, and can carry out the higher model test of similarity.
The technical solution adopted in the utility model is: comprise base, internal mold and external mold, and described external mold center is provided with the outer nib of Tunnel-hole shape, and one end of external mold is arranged on base; Described internal mold is arranged in the outer nib of external mold, and leaves tunnel tunnel-liner between outer nib and build groove.
Above-mentioned tunnel-liner model is built in instrument, described external mold is cuboid, and external mold comprises two exterior sheathings, and the face that two exterior sheathings are relative is respectively equipped with groove, two exterior sheathings are docking together by the geometrical clamp in outside, the outer nib of the groove composition Tunnel-hole shape of two exterior sheathings.
Above-mentioned tunnel-liner model is built in instrument, and described internal mold comprises four blocks of inner formwords and inner mould core, and inner mould core is cross section is trapezoidal prism structure, and four blocks of described inner formwords are arranged on four sides of inner mould core respectively.
Above-mentioned tunnel-liner model is built in instrument, and the bottom surface of described inner formword base is dorsad provided with and is obliquely installed, and be communicated with the through hole of inner formword and inner mould core contact surface, the fixing iron tip passes this through hole and be fixed on inner mould core by inner formword.
Above-mentioned tunnel-liner model is built in instrument, and the bottom surface towards base of internal mold is provided with groove, is provided with and gets core iron silk in groove.
Above-mentioned tunnel-liner model is built in instrument, and base is provided with the groove of internal mold cross sectional shape and the hold-down bars with four cuboids, and four hold-down bars are positioned at the outside of external mold sidewall.
Compared with prior art, the beneficial effects of the utility model are:
1) the utility model structure is simple, easy to operate.
2) each part accurate positioning of the utility model, guarantees that built mold shape is stablized; Internal mold of the present utility model comprises four pieces of templates and core rod, and external mold comprises two pieces of templates, makes to be convenient in demoulding; The connection everywhere of the utility model internal mold all adopt curve and circular arc tangent, transitions smooth, can not be model produce obviously uneven.
3) the utility model the tunnel-liner model of building out be close to Practical Project, thoroughly solve the problem that teaching comparatively abstract and students in traditional tunnel is not easy to understand, the tunnel-liner model simultaneously obtained can carry out the higher model test of similarity in a large number.

Detailed description of the invention
below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises external mold 1, internal mold 2, geometrical clamp 3 and base 4, described external mold 1 profile is cuboid, external mold 1 comprises two exterior sheathings, the face that two exterior sheathings are relative is respectively equipped with groove, two exterior sheathings are docking together by the geometrical clamp 3 in outside, the outer nib 11 of the groove composition Tunnel-hole shape of two exterior sheathings.External mold 1 is arranged on base, and one end of external mold 1 base 4 dorsad is provided with pull bar 12, can carrying mould or separately two blocks of exterior sheathings by pull bar 12.
Internal mold 2 is arranged in outer nib 11, leaves tunnel tunnel-liner and build groove 5 between internal mold 2 and external mold 1.Described internal mold 2 comprises four blocks of inner formwords and inner mould core 21, inner mould core 21 for cross section be trapezoidal prism structure, four blocks of inner formwords are arranged on four sides of inner mould core 21 respectively.The bottom surface of four blocks of described inner formwords base is dorsad respectively equipped with and is obliquely installed, be communicated with the through hole of inner formword and inner mould core 21 contact surface, the fixing iron tip 6 passes this through hole and is fixed on inner mould core 21 by inner formword.As shown in Figure 3, inner mould core 21 is provided with groove towards the bottom surface of base 4, is provided with and gets core iron silk 22 in groove, and during the demoulding, inner mould core takes out by the core iron silk 22 of getting on it.
As shown in Figure 4, described base 4 is provided with the groove 41 of internal mold cross sectional shape and the hold-down bars 42 with four cuboids, and one end of described external mold 1 is fixedly mounted on base 4, and four hold-down bars 42 are positioned at the outside of the sidewall of external mold 1.Hold-down bars 42 pairs of external molds 1 are located, and groove 41 pairs of internal molds 2 are located.
Specific implementation process of the present utility model is: when building, and builds toughness model stoste toward building in groove 5.Building body to be poured pulls out the iron tip 6 after solidifying, and is removed by base 4, extracts core by getting core iron silk 22.Four blocks of inner formwords are knocked toward original inner mould core 21 position successively, itself and pour mass are separated from.Take off geometrical clamp 3, separate two blocks of exterior sheathings by pull bar 12, pour mass and external mold 1 are separated from.
