The utility model discloses a mold for making a concrete direct tension test piece, which comprises a mold groove composed of a bottom plate and two side plates vertically fixed on both sides thereof, the inner sides of the two ends of the two side plates are A plurality of oppositely arranged vertical slots are provided respectively, and an end plate and an inner plate are inserted into the vertical slots at both ends of the mold groove, and the end plate and the inner plate are respectively provided with coaxially arranged An axial threaded through hole for placing the screw, and the inner plate is inserted into the innermost vertical slot of the mould. In the utility model, since the side of the end plate and the inner plate are provided with axial threaded through holes, the screw rod can be pre-installed in the mold groove before pouring the concrete, so the test piece after pouring and forming can be fixed on the concrete by stretching. The screw rods at both ends of the test piece are used to test the tensile strength of the concrete, which solves the cumbersome process of making practical molds for direct tensile test pieces of concrete.
Description
Technical field
The utility model relates to mould, is specifically related to make the mould of the direct extension test part of concrete.
Background technology
Concrete refers to by the compound that cementitious matter, graininess are gathered materials, water and the chemical admixture that need to add and mineral admixture form by the proper proportion mixing, and what after sclerosis, form has a compound substance of piling up structure.Concrete is one of contemporary topmost civil engineering material, has that abundant raw material, cheap, production technology are simple, normability, random molding, characteristics that rigidity is large.Concrete also has the characteristics such as compressive strength is high, good endurance, strength grade wide ranges simultaneously.These characteristics make its usable range very extensive, not only in various buildings and science of bridge building, use, and are exactly that in the exploitation, geothermal engineering of shipbuilding industry, mechanical industry, ocean, concrete is also important material.
When more concrete physical properties are tested, generally can make corresponding test block with mould, as by the agent on crack resistance of concrete compression mould, can be made into the concrete anti-compression test block.But, lack for a long time a kind of for make the concrete tensile strength test block simple, accurately, practical mould that cost is low, bring larger inconvenience to the test concrete tensile strength, make thus China's engineering circles for a long time with other method test concrete tensile strength, be unfavorable for obtaining the true tensile strength of concrete, may make engineering construction produce some potential safety hazards.
The utility model content
Technical problem to be solved in the utility model is to solve to lack the problem of making the practical mould of the direct extension test part of concrete.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of mould of making the direct extension test part of concrete, comprise by a base plate and vertical two mold slots that side plate forms that are fixed in its both sides, be respectively equipped with a plurality of vertical slot that are oppositely arranged on the medial surface at the two ends of two blocks of described side plates, all be fitted with an end plate and an inner panel in the vertical slot at described two ends, on described end plate and inner panel, be respectively equipped with coaxial setting for placing the axial thread through hole of screw rod, described inner panel is plugged in the most inboard vertical slot of mould.
In such scheme, the two ends of every block of described side plate are provided with 3 described vertical slot.
In such scheme, the two ends of two described side plates interfix by horizontal screw bolt respectively.
In such scheme, the quantity of described side plate both ends horizontal screw rod is respectively 2, and described 2 horizontal screw bolts set gradually from top to bottom.
In such scheme, the horizontal screw bolt of described downside is fixed on described base plate by vertical rod.
In such scheme, the quantity of described vertical screw is 2.
The utility model, because be provided with the axial thread through hole on the side of end plate and inner panel, can install in advance screw rod in mold slots before casting concrete, test concrete pulling strengrth so build the screw rod that concrete test part after moulding can be fixed in concrete test part two ends by stretching, solved the loaded down with trivial details problem of present making Analysis of Concrete Tensile test block process.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The schematic diagram that Fig. 2 is the utility model end plates and inner panel;
In figure: 1-base plate, 2-side plate, 3-end plate, 4-tapped through hole, 5-horizontal screw bolt, 6-vertical screw, 7-inner panel.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, Fig. 2, shown in Fig. 3, what the utility model provided comprises by a base plate 1 and vertical two mold slots that side plate 2 forms that are fixed in its both sides, be respectively equipped with 3 vertical slot that are oppositely arranged on the medial surface at the two ends of two blocks of side plates 2, be respectively equipped with 3 vertical slot that are oppositely arranged on the medial surface at the two ends of two blocks of side plates 2, all be fitted with an end plate 3 and an inner panel 7 in the vertical slot at two ends, on end plate 3 and inner panel 7, be respectively equipped with coaxial setting for placing the axial thread through hole 4 of screw rod, tapped through hole 4 can standing screw, it can not be moved forward and backward in the process of building and changes to expose size, end plate and inner panel 3, 7 can standing screw, it can not be moved up and down in casting process and affect screw rod centering degree of accuracy.Can also change concrete screw rod by the end plate 3 with different plug-in mountings position and expose size.End plate 3 and inner panel 7 can take out, and end plate 3 and inner panel 7 by being replaced with the different size through hole, can meet in concrete the needs that bury screw rod multiple diameter size.The two ends of two side plates 2 of mold slots interfix by 2 horizontal screw bolts 5 respectively, and 2 horizontal screw bolts arrange successively from top to bottom, and the horizontal screw bolt 5 of downside is fixed on base plate 1 by two vertical screw 6.The utility model is linked together by vertical slot and screw rod, and convenient disassembly is easy to the replacing of concrete demoulding and damaged parts.
In use, first determine the size that exposes of screw rod, thereby determine the vertical slot of the insertion correspondence of end plate 3.Then select end plate 3 and the inner panel 7 suitable with screw rod, be inserted in mold slots.Then from the tapped through hole 4 of both mold ends end plate 3, inwardly screw in respectively screw rod, make size that end plate 3 both sides expose screw rod and exposing of setting in advance measure-alike.Build quantitative concrete in mould, after concrete thoroughly solidifies, unclamp horizontal screw bolt 5 and vertical screw 6, the Analysis of Concrete Tensile test block be shaped is carried out to the demoulding and get final product.The utility model, because be provided with axial thread through hole 4 on end plate 3 and inner panel 7 sides, can install in advance screw rod in mold slots before casting concrete, test concrete pulling strengrth so build the screw rod that test block after moulding can be fixed in concrete test part two ends by stretching, solved the loaded down with trivial details problem of present making Analysis of Concrete Tensile test block process.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
