Abstract
The utility model relates to a cone-frustum-shaped penetration test device for concrete. The cone-frustum-shaped penetration test device comprises a cover die; the cover die is formed by connecting two semicircular trying dies by a threaded rod, wherein the connection of the two semicircular trying dies is sealed by a vertical sealing tape; and an annular sealing rubber die strip is sleeved on a test piece. The cone-frustum-shaped penetration test device for the concrete can overcome the defects of the existing penetration test device, is convenient to mount, small in consumption of sealing material, and high in test success ratio by once mounting, greatly reduces the labor intensity, reduces the environmental pollution arising from the sealing material, increases the testing efficiency, reduces the consumption of the sealing material, increases the success ratio of once testing, and effectively guarantees the quality of testing.
Description
Technical field
The utility model relates to a kind of infiltration experiment device, especially a kind of truncated cone concrete infiltration experiment device that is applicable to concrete and mortar permeability test.
Background technology
At present; Sealing is carried out in general space of adopting encapsulant to fill between test specimen and the die trial in the concrete permeability test method, and the cone die trial is connected with permeameter through screw rod and O-ring seal, carries out permeability test by permeameter certain water pressure of annotating; Its encapsulant adopts usually that paraffin adds rosin, cement adds butter etc.; Also have and adopt glass silica gel, water-repellent paint, special-purpose sealing compound and rubber sleeve and bungee to seal, these methods generally all are to adopt special-purpose pressurized equipment that test specimen is pressed in the die trial, install inconvenient; And all there is a risk of seal failure; Can not single test success, the also poisonous or very much not environmental protection of smell of some material needs to consume defectives such as encapsulant.
Summary of the invention
The utility model technical matters to be solved provides a kind of truncated cone concrete infiltration experiment device, can overcome the defective of existing infiltration experiment device, carry easy for installation, encapsulant consumption is few, one-step installation success of the test rate is high.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of truncated cone concrete infiltration experiment device; Comprise cover die; Cover die is formed by connecting through screw rod two semicircle die trials, and the junction of two semicircle die trials is through vertical sealing strip driving fit, and hoop caulking gum mould band is enclosed within on the test specimen.
Vertical sealing strip is embedded in the semicircle vertical slot of semicircle die trial.
Hoop caulking gum mould band is made up of last hoop caulking gum mould band that is enclosed within test specimen upper surface and lower surface respectively and following hoop caulking gum mould band.
Hoop caulking gum mould band is the monoblock rubber pattern band that is enclosed within the frustum of a cone side of test specimen.
The truncated cone concrete infiltration experiment device that the utility model provides, two semicircle die trials closely link together die trial and test specimen through screw rod, pass through vertical sealing strip hermetic seal between two semicircle die trials; Two semicircle die trials reach combining closely of die trial and test specimen through the rubber diaphragm of wedging ring on test specimen when clamping test specimen; Thereby reach the effect of hermetic seal, can overcome the defective of existing infiltration experiment device, carry easy for installation, encapsulant consumption is few; One-step installation success of the test rate is high; Alleviate labour intensity greatly, reduced the environmental pollution that encapsulant brings, improved experiment work efficient, reduced encapsulant consumption; Improve the single test success ratio, guaranteed test mass effectively.
