Abstract
The utility model provides a molding mould of a test piece for testing the early strength of sprayed concrete. The mould is a three-unite mould and comprises a mould separation plate and a bottom plate, wherein the mould separation plate is fixedly connected with the bottom plate by a screw; the mould is provided with a handle. The molding mould of the test piece for testing the early strength of the sprayed concrete can be used for manufacturing the test piece for directly testing the early strength of the sprayed concrete; the molding mould is simple and reliable in structure and is convenient to mould.
Description
Technical field
The utility model relates to a kind of sprayed concrete early strength test specimen molding mould, adopts the sprayed concrete test specimen of this Mold Making, can be for directly measuring sprayed concrete early strength.
Background technology
In underground engineering support work, the development of the early strength of sprayed concrete is extremely important for early stage supporting at present.The assay method of sprayed concrete strength is divided into direct method and indirect method at present.Direct method adopts the large plate core drilling method of spray and on-the-spot core drilling method, but core drilling method only has concrete strength to reach 10MPa, could be suitable for above, is not suitable for early age strength of concrete and detects; Indirect method has a loading method and pull method, and the testing result that these methods draw need to, in conjunction with the linear relationship of they and concrete strength, could be inferred and concrete strength; And these linear relationships are all relevant with concrete raw material, test facility and test method, deterministic process is more loaded down with trivial details.And can directly measure the test specimen of sprayed concrete early strength, and in processing, there is the place should be noted that, the sprayed concrete early strength test specimen molding mould that the utility model provides, the test specimen of producing can directly carry out the mensuration of early strength.
Utility model content
The utility model provides a kind of sprayed concrete early strength test specimen molding mould, has solved and can, for directly measuring the making of the test specimen of sprayed concrete early strength, it is characterized in that:
An early strength test specimen molding mould, described mould is three gang moulds, comprises mould dividing plate and base plate, and described mould dividing plate is fixed by screw and base plate, and described mould is provided with handle.
Between described mould dividing plate, by hexagon socket head cap screw, be fixedly connected with.
Described mould dividing plate adopts stainless steel material or cast iron materials.
Described mould inner side is coated with thin layer release agent.
Described sprayed concrete early strength is tested the simple and reliable for structure of specimen molding mould, convenient formation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail,
Fig. 1 is the structural representation of the sprayed concrete early strength test specimen molding device that provides of the utility model;
Fig. 2 is the A-A diagrammatic cross-section of Fig. 1;
In figure, 1, mould dividing plate; 2, base plate; 3, fixed screw; 4, handle.
Embodiment
As depicted in figs. 1 and 2, a kind of sprayed concrete early strength test specimen molding mould, described mould is three gang moulds, comprises mould dividing plate 1 and base plate 2, and described mould dividing plate 1 is fixing with base plate 2 by fixed screw 3, and described mould is provided with handle 4.Between described mould dividing plate 1, by hexagon socket head cap screw, be fixedly connected with, it adopts stainless steel material or cast iron materials.Described mould inner side is coated with thin layer release agent.
Application process is as described below:
(1) by the 1 use hexagon socket head cap screw assembling of mould dividing plate, then dividing plate 1 is fixed on base plate 2 by four screws 3, in mould dividing plate 1 inner side, smears thin layer release agent;
(2) mould is vertically placed, at internal spray concrete, during injection, first mold bottom should be full of to prevent the defect that causes due to resilience, the concrete of injection should exceed die top slightly;
(3) after spray completely, mould is set level, with trowel, removed unnecessary concrete floating;
(4) after sprayed concrete final set, mould is taken apart, taken out test specimen, be placed in the maintenance environment same with on-site concrete and carry out maintenance.
Claims (4)
1. a sprayed concrete early strength test specimen molding mould, is characterized in that: described mould is three gang moulds, and comprise mould dividing plate and base plate, described mould dividing plate is fixed by screw and base plate, and described mould is provided with handle.
