Abstract
The utility model relates to a concrete test block molding mold for concrete electric flux measurement, comprising a bottom mold (2) which has a side mold (1); an inflation demolding hole (3) is arranged in the side mold area on the bottom mold; the side mold is a cylindrical side mold. The utility model has the following technical effects: 1) the molded concrete test block is employed, saving the concrete core sampler and the concrete cutter and simplifying the test block production process; 2) the light mold and convenient molding greatly reduce the test workload; 3) compressed air is inflated into the mold bottom through the tapered inflation demolding hole, and demolding agent is coated on the bottom die and the inner wall of the side die, so that the demolding is convenient.
Description
Technical field
The utility model relates to a kind of concrete to be detected, tests and use the concrete formation mould, relates in particular to a kind of concrete test block mould that is used to measure concrete charge pass.
Background technology
Concrete permeance property is an important indicator in the concrete durability, the height of concrete electric flux size reflection concrete opposing chloride permeability ability, can estimate concrete perviousness height fast, standards such as " the provisional technical regulation of Line for Passenger Transportation high performance concrete ", " concrete for hydraulic structure testing regulations ", " concrete for marine works structural anticorrosion erosion technical manual " all with concrete electric flux rapid assay methods as estimate concrete permeability can foundation.Survey concrete charge pass with test block normally concrete pass through core boring sampling, be cut into certain thickness with cutting machine again, polish through sander at last and make, though this test block that makes by core boring sampling can reflect the concrete permeance property of construction preferably, but, required instrument and equipment is more, and it is bigger to bore core machine, cutting machine complicated operation and noise, is difficult for realizing in the laboratory.
Chinese patent CN2319482Y discloses a kind of mould that is used as concrete test block, it is by a bottom surface and four cube structures that vertical plane is formed, the concrete test block that processing obtains is a cube structure, this structural limitations its usable range, this mould can only be used as the test block usefulness of preparation mechanical performance of concrete, and can not process the concrete test block of the test that is used for concrete permeance property.
Summary of the invention
Technical problem to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, convenient formation can be used to measure the concrete test block mould of concrete charge pass.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
It comprises bed die, and bed die is provided with side form, and the bed die in the side form zone is provided with inflation demoulding hole, and its difference is that described side form is the right cylinder side form.
In the above-mentioned technical scheme, be provided with reinforcement between the outer wall of described right cylinder side form and the bed die.
In the above-mentioned technical scheme, described inflation demoulding hole is the little bellmouth of outer imperial palace.
In the above-mentioned technical scheme, the width of described bed die should be greater than the external diameter of right cylinder side form.
In the above-mentioned technical scheme, the height of described right cylinder side form should be greater than the concrete test block size 2-10mm of corresponding test standard requirement.
In the above-mentioned technical scheme, on the bed die in the described side form zone and the inwall coating release agent of described side form.
Compared with prior art, the utility model has been obtained following technique effect:
1, utilizes the mould molding concrete test block, saved concrete drill core sampling machine, concrete cutting machine, simplified the preparation process of test block;
2, mould is light and handy, and convenient formation has reduced the experiment work amount largely;
3, the taper inflation demoulding hole by the bottom charges into pressurized air and passes through on the bed die in the side form zone and the inwall coating release agent of described side form to the bottom, makes the demoulding very convenient.

Embodiment
The utility model will be further described with executing example below in conjunction with accompanying drawing.
Embodiment of the present utility model shown in Fig. 1-4, a kind of concrete test block mould that is used to measure concrete charge pass, it comprises bed die 2, bed die is provided with right cylinder side form 1, be provided with 6 reinforcements 4 between the outer wall of right cylinder side form and the bed die, can certainly other number, when right cylinder side form 1 combined firmly with bed die 2, reinforcement 4 can omit.Bed die 2 in the right cylinder side form zone is provided with the little taper inflation demoulding hole 3 of outer imperial palace, and it is located at the center of bed die 2.In general the width of described bed die should be greater than the external diameter of right cylinder side form, and the shape of bed die 2 is not limit.Wherein, the test block size design that the internal diameter of right cylinder side form 1 requires according to corresponding test standard, the height of right cylinder side form 1 should polish usefulness for test block greater than the concrete test block size 2-10mm of corresponding test standard requirement.During use earlier on the bed die in the side form zone and the inwall coating release agent of described side form.Entire die can be made by engineering plastics.
The utility model generally comprises following use step in the fabrication of concrete test block:
1, with mould inside and outside wall coating release agent;
2, with the concrete depositing that stirs in mould, vibration moulding;
3, after concrete hardening, pressurized air is injected from the inflation demoulding hole of mold bottom, mould rises because of air pressure, and test block is deviate from;
4, with sander the test block upper and lower surface is polished to the experimental standard required thickness, promptly make and survey the concrete test block that concrete charge pass is used.
Described protection domain of the present utility model is not limited to the above embodiments, and other technical scheme identical with the utility model essence all belongs to the scope of the utility model protection.
