Description
Technical field
The present invention relates to a kind of concrete impervious test mould, belong to building detection technique field.
Background technology
Different buildings needs to adapt to different environment, needs to adopt water-tight concrete for the building that some seepage resistance demands are high, and water-tight concrete refers to that seepage-resistant grade equals to or more than the concrete of P6 level.And water-tight concrete needs through impervious test before use, to detect whether it reaches relevant criterion.
At present, be generally adopted paraffin Sealing Method, surface of test piece smear one layer dissolve in add the paraffin of a small amount of Colophonium.Then adopt press device to be pressed in the die trial that baking oven or electric furnace are preheated by test specimen, after off-test, re-use press device and sample is extruded.But adopting the method extremely inefficient, heating paraffin wax is also easy to cause danger, and sealing effectiveness is poor, drainage often occurs.
Another kind is to adopt cement to add grease seal method, first has to mix cement and butter in proportion thoroughly, then uniform application is in test specimen side, finally uses press device to be pressed in die trial by sample, after off-test, re-uses press device and is extruded by sample.Adopting the method complex steps, sample dismounting takes time and effort, and sealing effectiveness is poor, it is easy to drainage occur.
Except this, also having at present and use the ways such as rubber band, sealing ring, but all there is sealing effectiveness difference, sample loads and unloads the situations such as trouble.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem, it is provided that a kind of concrete impervious test mould.
The purpose of the present invention is achieved through the following technical solutions:
Concrete impervious test mould, including test mould shell, dismountable sealing member being placed in inside test mould shell and the push rod being removably connected to test mould cover top portion, described test mould shell is the cavity of bottom opening, the bottom of described test mould shell extends to form a test edge outside border, described sealing member is the hollow tube-shape of bottom opening, and described inner seal diameter is suitable with sample external diameter.
Preferably, described test mould cover top portion offers a tapped through hole, and described push rod includes a screw thread bottom bar and is vertically connected at the cross bar at bottom bar top, and described push rod is connected with test mould outer casing screw by screw thread bottom bar.
Preferably, the sidewall bottom of described sealing member offers a V-type mouth.
Preferably, described sealing member is flexible seal ring.
Preferably, described test mould cover top portion is provided with reinforcement.
Preferably, described reinforcement threadingly border, hole is the end face that divergent shape is distributed in test mould shell.
Preferably, described reinforcement is provided with three.
Preferably, described sealing member medial surface bottom is provided with sealing bulge loop, and described sealing bulge loop at least gap is provided with 3
Beneficial effects of the present invention: make the loading, unloading of sample all need not by forcing press, time saving and energy saving, make the mixed impervious experiment of earth become simple, efficient.Also there is excellent sealing property simultaneously, pressure up to more than 1.5MPa, the success rate of test is greatly improved.

Detailed description of the invention
The present invention specifically discloses a kind of concrete impervious test mould, in conjunction with shown in Fig. 1 to Fig. 5, including test mould shell, dismountable sealing member being placed in inside test mould shell and the push rod being removably connected to test mould cover top portion.
Described test mould shell 12 is the cavity of bottom opening, the bottom of described test mould shell 12 extends to form a test edge 11 outside border, described test mould outer casing top surface 13 offers a tapped through hole 14 and reinforcement 15, and described reinforcement 15 threadingly border, hole 14 is the end face 13 that divergent shape is distributed in test mould shell.The quantity of described reinforcement 15 is configured as required, and in the present invention, the size of test model adopts three reinforcements as required.
Described push rod includes a screw thread bottom bar 22 and is vertically connected at the cross bar 21 at bottom bar 22 top, and described push rod is threadeded with test mould shell 12 by the bottom bar 22 of screw thread.
Described sealing member is flexible seal ring, and the described sealing member 3 hollow tube-shape in bottom opening, described sealing member 3 internal diameter is suitable with sample external diameter.In order to further ensure sealing when test, the sidewall bottom of described sealing member offers a V-type mouth 31, and to ensure after pressurized, V-type mouth 31 can deform, better to adapt to specimen shape.
Certainly, described sealing member can also be provided with the bulge loop 33 strengthening sealing property in bottom inside face, and described bulge loop 33 is provided with at least 3, is provided with gap 32 between described bulge loop 33.
The work process of the lower present invention described briefly below:
It is placed on sample to be detected to by sealing member 3, then test mould shell 12 is set on sealing member 3, tighten the fixed screw on test mould shell by normal operating, carry out tightening of screw especially by the screwed hole on test edge 11.
After sealing member is installed and put in place, the medial surface of sealing member can be close to sample outer ring；Sealing member lateral surface can be attached to test mould shell and put into medial wall, accordingly even when first provide initial sealing effectiveness when not having water pressure.
After starting pressurization, water enters in the middle of V-groove, and by sealing ring respectively to sample and test mould shell extruding, plays further sealing function；Along with hydraulic pressure raises, sample up can move along sealing member, sealing member whole surface test sample crimp, thus the effect reaching to fully seal is until completing test.
After off-test, first unclamp the fixed screw of test mould shell and test platform, dismountable push rod is screwed in the tapped through hole of test mould cover top portion, and apply power test specimen is ejected downwards.After sample departs from test mould shell, mention push rod, it is possible to from test platform, pull down die trial, and from sample, take out sealing member, finally sample is moved down testing stand.
The invention enables the loading, unloading of sample all need not by forcing press, time saving and energy saving, make the mixed impervious experiment of earth become simple, efficient.Meanwhile, bottom the existence of sealing member and sealing member, the setting of V-type mouth enhances it and has excellent sealing property, pressure up to more than 1.5MPa, and the success rate of test is greatly improved.
The present invention still has multiple specific embodiment.All technical schemes that all employings are equal to replacement or equivalent transformation and are formed, all fall within the scope of protection of present invention.
