Description
Technical field
The utility model is related to a kind of civil engineering test mould, specially prepares the experiment of rubber grain concrete sample
Mould.
Background technology
With developing rapidly for building trade, increasing New Building Materials are applied in architectural engineering, in city
In city's railway traffic engineering, rubber grain concrete receives much concern as a kind of New Supporting material, due to its special mechanics
Property preferably plays its effect, it is necessary to carrying out physical mechanics test to it can make the best use of everything.
During obtaining rubber grain mechanical performance of concrete by indoor mechanical test, due to rubber grain concrete
Particularity, in addition without targetedly experiment mould, so that existing during rubber grain concrete sample is prepared
Problems, test specimen vibrate it is insufficient or vibrate operation it is extremely complex, during form removal, easily cause surface of test piece to damage,
The mechanical property finally obtained differs larger with its essence.Therefore, rubber can either be ensured by needing a kind of new experiment mould badly
The effect of vibrating of grain concrete, can reduce the surface damage caused during form removal again.
Utility model content
The utility model provides a kind of experiment mould for preparing rubber grain concrete sample, and the mould is simplifying concrete
The quality of concrete sample is improved while test specimen manufacturing process, it is adaptable to the making of civil engineering test concrete sample.
The utility model is adopted the following technical scheme that：
A kind of experiment mould for preparing rubber grain concrete sample, including die main body, die main body include two and half
Interface is threaded outside cylinder mold side wall, mould side wall two ends, mould side wall both sides are respectively equipped with fastener, fastened
Device fastens two pieces of mould side wall connections.Die main body top is provided with cover plate, and cover plate lower inside is provided with connection screw thread, mould
Lower body part is connected with base, and base is provided with fixing groove, and die main body is stretched into fixing groove, and screw thread is provided with fixing groove.Lid
Plate is threadedly coupled with mould side wall by cover plate, and mold base is linked together by the screw thread in fixing groove and mould side wall.
In addition, chassis interior is provided with cushion rubber layer, too strong vibration can be buffered by cushion rubber layer cushioning effect, it is ensured that test specimen
Integrality.
The bottom of the base is threaded provided with magnet, stable magnet surrounding is stablized, and stable magnet connects with whorl of base
Connect, the setting of stable magnet can ensure the stability of base, and the two is connected through a screw thread, and is further ensured that stable connection.
The cover plate main body is provided with relief hole, process of vibrating discharges the pressure and gas inside test specimen by relief hole
Body.It is preferred that, relief hole is a diameter of 3mm circular hole.
The fastener includes two groups of fastening bolts, and every group is provided with three fastening bolts, and the setting of the fastener can
Ensure that two mould side walls are closely connected, and fit like a glove.
Advantage of the present utility model and have the beneficial effect that：
The experiment mould of the utility model as compared with the past is characterized in that, its upper and lower ends be respectively designed with cover plate and
Steady base, and connected by hickey.During rubber grain concrete sample is prepared, with shaking for vibrator
Dynamic, thread head can ensure the density of rubber grain concrete and the precision of test specimen, and Steady base realizes mould and vibration
The steady contact of platform, and the cushion rubber layer of chassis interior has reached the purpose for buffering energy.During form removal, by twisting
Upper and lower ends screw is opened, opening the fastening bolt of mould side wall can completely take out test specimen, ensureing test specimen apparent mass
Under the premise of, it is easy to operate, practical.
