The utility model discloses make the sample the dress, it need be with the help of the press to unload all not, labour saving and time saving makes and mixes the impervious experiment of earth and become simple, high -efficient. Simultaneously, the setting up of the existence of sealing member and sealing member bottom V type mouth has strengthened it and has had good sealing performance, and withstand voltage reaching more than the 1.5MPa has increased substantially experimental success rate.
Description
Technical field
This utility model relates to a kind of concrete impervious test mould, belongs to building detection technique field.
Background technology
Different buildings needs to adapt to different environment, needs to use 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, general use paraffin Sealing Method, surface of test piece smear one layer dissolve in add the paraffin of a small amount of Colophonium.Then use 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 using 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 use 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.Using the method complex steps, sample dismounting to take time and effort, sealing effectiveness is poor, drainage easily occurs.
Except this, the most also using the ways such as rubber band, sealing ring, but it is poor all to there is sealing effectiveness, sample loads and unloads the situations such as trouble.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of concrete impervious test mould.
The purpose of this utility model 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 formation one 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
The beneficial effects of the utility model: the loading, unloading of sample all be need not by forcing press, time saving and energy saving, make the mixed impervious experiment of earth become simple, efficient.The most also there is excellent sealing property, pressure up to more than 1.5MPa, the success rate of test is greatly improved.

Detailed description of the invention
This utility model 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 formation one 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 this utility model, the size of test model uses 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, the described sealing member 3 hollow tube-shape in bottom opening, and 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, preferably 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.
Work process of the present utility model under 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 in the case of 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, the test sample crimp of sealing member whole surface, 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, die trial can be pulled down from test platform, and from sample, take out sealing member, finally sample be moved down testing stand.
This utility model makes the loading, unloading of sample all need not by forcing press, time saving and energy saving, makes 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.
This utility model still has multiple specific embodiment.All employing equivalents or equivalent transformation and all technical schemes of being formed, all fall within this utility model claimed within the scope of.
