Abstract
The utility model discloses a test mould for casting a variable cross section cement base material specimen, which comprises an outer mould consisting of two side plates, two end plates and a bottom plate; the inner sides of the two side plates in the outer mould are respectively connected with two inner templates in a detachable way; both ends of each inner template are respectively connected with the two side plates of the outer mould through prismatic pillars, and are provided with grooves; and the prismatic pillars are provided with verges used to insert the prismatic pillars into the inner template grooves. Compared with the prior art, in the test mould, the inner templates are connected in the outer mould in the detachable way; and various lengths of a transition section and various widths of the middle cross section of the specimen when the cross section of the cement base material specimen is changed are realized by selecting different cross sectional sizes of the prismatic pillars, so as to meet different requirements. The test mould has the advantages of simple structure, convenient installation and reusability, and is applicable in the variable cross section cement base material specimen casting of material labs, engineering construction units and quality inspection departments.
Description
Technical field
The utility model relates to a kind of die trial of building variable cross section cement-based material test specimen, belongs to the concrete construction field.
Background technology
Cement-based material axial compressive strength and tensile strength are the key parameters of its mechanical property.Generally making the test specimen that axial compressive strength and tensile strength adopted is the prism form.But in some cases, the researchist needs to study axial compressive strength and tensile strength by the variable cross section test specimen.But for building the variable cross section test specimen, do not have special die trial at present, need testing crew die trial to be improved usually temporarily, the flatness of the test specimen of being built and unitarity are difficult to reach requirement.
Summary of the invention
The purpose of this utility model is exactly in order to solve the above problems, and a kind of die trial of building variable cross section cement-based material test specimen is provided, this die trial simple structure, and mounting or dismounting are convenient, can build the variable cross section test specimen of middle part different-thickness.
The technical solution of the utility model is: a kind of die trial of building variable cross section cement-based material test specimen, comprise the external mold that constitutes by two blocks of side plates, two end plates and a base plate, the inboard of two blocks of side plates is detachable respectively in described external mold is connected with two blocks of inner formwords, described in the two ends of lamina membranacea be connected with two blocks of side plates of described external mold by triangular prism shaped buttress respectively.
The two ends of described inner formword have groove, and described triangular prism shaped buttress is provided with triangular prism shaped buttress is inserted tooth mouth in the described inner formword groove.
Triangular prism shaped buttress is by being bolted to above the side plate.
Compared with prior art, the utility model relates to a kind of die trial of building variable cross section cement-based material test specimen, lamina membranacea in the detachable connection in external mold, and by selecting the different sectional dimension of triangular prism shaped buttress, the different length of the transition section when realizing the cement-based material variable cross section and the different width in test specimen cross section, middle part, thus satisfy different requirements.

Embodiment
Be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model relates to a kind of die trial of building variable cross section cement-based material test specimen, comprise by two blocks of side plates 1, the external mold that a two end plates 2 and a base plate 3 constitute, its latus inframedium 1 and end plate 2 are by assembling by fixture 4, the inboard of two blocks of side plates 1 is provided with two blocks of inner formwords 6 in external mold, have groove 8 at the two ends of inner formword 6, on triangular prism shaped buttress 5, be processed with tooth mouth 9, the two ends of interior lamina membranacea 6 are connected with plugging together with triangular prism shaped buttress 5 of groove 8 by tooth mouth 9 respectively, triangular prism shaped buttress 5 is connected by bolt is detachable with two blocks of side plates 1 of external mold, and the xsect of triangular prism shaped buttress is a triangle.
Build the end when not having the test specimen of built-in fitting when needs, with two blocks of side plates 1 of die trial, two end plates 2 and base plate 3 assemble by fixture 4,
Mixture such as cement-based material such as concrete, mortar is cast in the cavity that is surrounded by base plate 3, side plate 1, end plate 2, triangular prism shaped buttress 5 and interior plate 6.After treating the specimen molding sclerosis, unclamp fixture 4 and can take out test specimen.
