Background technology：
Concrete is the existing artificial stone material being widely used under construction, for certain buildings, as waterwork, it is underwater,
In water, underground and other architectural engineerings, it is desirable that building has special performance-anti-permeability performance；So-called anti-permeability performance refers to structure
The performance that water and/or other liquid (light oil, heavy oil) media permeate under pressure can be resisted by building material used in object.
Concrete impervious instrument is mainly used for the measurement of concrete impermeability experiment and anti-penetration grade.It can also be used simultaneously
It does measurement and the quality examination of construction material gas permeability, therefore has obtained the departments such as related production, construction, design, teaching and research
It is widely used.
Concrete impervious instrument includes that Anti-leakage instrument main body and die trial inject water into Anti-leakage instrument main body, directly first when in use
Until water is overflowed out of Anti-leakage instrument main body die holder, so as to the air in discharge system；Then good according to standard curing
Coat the sealing material (sealing wax or sealing wax) of fusing in test specimen side；Die trial is heated to 40 DEG C, it is then die-filling, dress is pressed into examination
The die trial of part is mounted on the workbench of Anti-leakage instrument, is aligned with die holder, and uniformly tighten cap nut；Last opening controlling valve,
Hydraulic pressure is sent into corresponding examination body.
But existing die trial is the cylindrical member of both ends open as shown in Figure 1, one end integrally formed with die holder
Corresponding ring flange；The die cavity that the test specimen for being coated with sealing material is packed into die trial, the then (helical pressure on press are needed when die-filling
Machine or the pressure experiment machine for borrowing laboratory) test specimen is pressed into die trial and is cooled to room temperature；It is being taken off after the completion of experiment
Mould, cumbersome, great work intensity, test block and mold repeatedly have bad luck turnover, in die-filling, knockout course, need to use melt paraffin,
The equipment such as mold baking oven, the auxiliary materials such as consumption paraffin, rosin, the press operation time is long, and there are security risks.
Utility model content：
To solve the above problems, the purpose of this utility model is to provide a kind of concrete impervious testing molds.
The utility model is implemented by following technical solution：A kind of concrete impervious testing mold, including top and bottom end opening
" cylinder type " die trial sleeve, the bottom terminal ends of the die trial sleeve are equipped with annular flange dish, close on the inner wall of the die trial sleeve
Envelope is equipped with expansion liner, and the expansion liner is equipped with charge and discharge gas port.
Further, the barrel longitudinal section of the die trial sleeve is that upper lower edge is equal there are two " H " type structure of card slot, described
Expansion liner is loop configuration, is set on the outer shroud of the expansion liner there are two card edge corresponding with two card slots, described
Card edge is connected in the card slot.
Further, the barrel longitudinal section of the die trial sleeve is " C " type structure of card slot there are two inner wall has, described swollen
Swollen liner is loop configuration, sets that there are two card edge corresponding with two card slots, the cards on the outer shroud of the expansion liner
Edge is connected in the card slot.
Further, the die trial sleeve is integrally formed with the annular flange dish.
Further, inflation/deflation quick coupling, the inflation/deflation quick coupling are equipped on the outside of the barrel of the die trial sleeve
It is connected to the charge and discharge gas port.
The advantages of the utility model：
The utility model is simple in structure, easy to operate, and before the test, expansion liner emptying is put into die trial sleeve
According to the good test specimen of standard curing, inflation/deflation quick coupling is connect with air pump then, squeezes into constant pressure, dress is pressed into test specimen
Die trial be mounted on Anti-leakage instrument workbench on, be aligned with die holder, and uniformly tighten cap nut；Last opening controlling valve, i.e.,
It is sent into hydraulic pressure to corresponding examination body；It is not required to ancillary equipment (die-filling, demoulding all-in-one machine, baking oven, melted paraffin wax equipment etc.), is not required to auxiliary
Help material (paraffin, rosin etc.), reduce experimentation cost, equipment avoids test block and mold from repeatedly having bad luck turnover, eliminate it is die-filling,
Loaded down with trivial details process and security risk are demoulded, operating process is simplified, saves cost of labor and time cost, improves work effect
Rate.
