Abstract
The utility model is related to a kind of concrete sample moisture determination devices, including bottom plate, button cover and heating unit, on bottom plate, the heating unit is placed on the bottom plate and in button cover for the button cover back-off, heating unit is in the peviform of upper opening, and having heaters is arranged in bottom wall；The inside for detaining cover upper wall is swelled downwards by week along to central gradual change, and is mounted with catch basin in bump pad；The side inner wall of the button cover is vertically arranged with several spine rings for enclosing and raising up.Using heating unit by after the steam discharge in concrete sample, steam is collected after condense to the cold by button cover, is covered on by measuring button and is measured front and back weight change and can measure aqueous in concrete sample, operates relatively simple, and measurement cost is relatively low.
Description
Technical field
The utility model is related to a kind of concrete sample moisture determination devices.
Background technology
The more big hole then therein of water content is more in concrete, and intensity is lower, in practical building construction process often
It needs to the water content in concrete.The prior art use destructive measurement method, by concrete sample air and
After steam discharge, the water content in concrete sample, the measurement method pair are obtained by measuring the air pressure change of the test space
The air-tightness of lab space is more demanding, so that testing cost is higher and operation difficulty is higher, thus instream factor
It is relatively low so that construction personnel only by virtue of experience estimates in usual construction operation.
Invention content
It is relatively low the purpose of this utility model is to provide a kind of use cost and operate conveniently concrete sample
Moisture determination device, is specifically realized by following technical scheme：
A kind of concrete sample moisture determination device, including bottom plate, button cover and heating unit, the button cover back-off is the bottom of in
On plate, the heating unit is placed on the bottom plate and in button cover, and heating unit is in the peviform of upper opening,
Having heaters is arranged in bottom wall；The inside for detaining cover upper wall is swelled downwards by week along to central gradual change, and is mounted with storage in bump pad
Sink；The side inner wall of the button cover is vertically arranged with several spine rings for enclosing and raising up.
The concrete sample moisture determination device, further design is, is set on the outside of the button cover upper wall
It is equipped with cooling bath.
The concrete sample moisture determination device, further design are that one side of button cover upper wall is set
It is equipped with air inlet hole, the other side is provided with exhaust vent.
The concrete sample moisture determination device, further design are that the air inlet hole, exhaust vent are distinguished
It is plugged with dismountable sealing-plug.
The concrete sample moisture determination device, further design are that the edge of the button cover is provided with
With the sealing ring of contacts baseplate.
The concrete sample moisture determination device, further design are that the button cover uses metal material
It is made.
The beneficial effects of the utility model are：
Using heating unit by after the steam discharge in concrete sample, steam is collected after condensing to the cold by button cover, is passed through
It measures button and covers on and measure front and back weight change and aqueous in concrete sample can be measured, operation is relatively simple, measures
Cost is relatively low；The droplet that steam can to the cold be condensed to generation by catch basin and spine ring is collected in button cover, and button covers on this
The variation of weight can reflect the water content in concrete sample under state；By the way that cooling bath is arranged on button cover so that cold
Condensate is mainly attached to the inner wall of button cover or enters catch basin, and avoiding part steam, evaporative condenser influences repeatedly in button cover bottom
Measurement result；The steam exclusion remained in after one-stop operation in button cover can totally be avoided by the way that air inlet hole, exhaust vent is arranged
It influences next measurement result.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is status diagram of the utility model embodiment in the steam of discharge button cover internal residual.
Fig. 3 is structural schematic diagram of the utility model embodiment after measurement.
Specific implementation mode
The utility model is further described below in conjunction with Figure of description and embodiment：
A kind of concrete sample moisture determination device as shown in the figure, including bottom plate 1, button cover 2 and heating unit 3, institute
The back-off of button cover is stated on bottom plate, the heating unit is placed on the bottom plate and in button cover, heating unit is presented
Having heaters is arranged in the peviform of portion's opening, bottom wall；The inside for detaining cover upper wall is swelled downwards by week along to central gradual change, and
Bump pad is mounted with catch basin 4；The side inner wall of the button cover is vertically arranged with several spine rings 5 for enclosing and raising up.
In operation, concrete sample is put into heating unit, heating unit is heated to concrete, the water in concrete
Divide evaporation to form steam to escape via the hole in concrete, final steam condenses to the cold in the inner wall of button cover, detains cover weight
Incrementss are the weight of steam.
Be provided with cooling bath 6 on the outside of the button cover upper wall so that exist between space in button cover wall and button cover compared with
The big temperature difference so that steam concentrates condensation to be attached in button cover wall or converge in catch basin, improves measurement accuracy.
One side of button cover upper wall is provided with air inlet hole 7, and the other side is provided with exhaust vent 8；Terminate in one-shot measurement
Afterwards, dry air is poured into button cover by air inlet hole and is discharged from exhaust vent, to which last time measurement to be attached in button cover
Moisture is discharged, it is avoided to influence next measurement result.Correspondingly, the air inlet hole, exhaust vent are plugged with dismountable close respectively
Blocking.
It is described button cover edge be provided with the sealing ring of contacts baseplate 9, avoid steam effusion button cover, air-tightness requirement
Requirement when far smaller than pneumatic process measures to equipment.
The button cover is made of metal material, to have preferable heat-conducting effect.
