Abstract
The utility model patent is related to a kind of steel reinforced concrete experiment bar reinforcement positioning device.The device mainly includes the gag lever post at top, reinforced hole, device outer wall, the rubber ring of bottom and the screw for fixing rubber ring.Reinforcing bar bottom is embedded in wooden template；Reinforcing bar upper end is placed in reinforced hole；Reinforcing bar is located at the center of test specimen when the gag lever post on top can effectively ensure that casting concrete, it is ensured that do not occur bias, and can be by the space casting concrete of top gag lever post, so as to improve the accuracy of experiment.The rubber ring of bottom can clamp test piece mould, prevent it from sliding.The present apparatus is reasonable in design, and reinforcing bar is effectively fixed on to the center of test specimen, improves the accuracy of experiment, with good application value and economic benefit, and the research reinforcing bar that is particularly suitable for use in is tested with concrete binding slip property.
Description
Technical field
The utility model is related to a kind of steel reinforced concrete experiment bar reinforcement positioning device, and the structure can be widely used in armored concrete
The making of test specimen, the research for the armored concrete bond-slip models that are particularly suitable for use in.
Background technology
Concrete has stable bonding and anchorage effect to reinforcing bar, be concrete and rebar can be work perfectly well as one it is whole
The cooperative basic premise of body.Armored concrete test specimen plays key effect to cohesive force measuring accuracy, and test reinforcing bar is with mixing
The device of solidifying soil adhesive property is divided to square body and round two kinds of forms.Most of square body is spelled by square wooden template
Connect and composition is formed, it is difficult to ensure the accuracy of device, and the position of reinforcing bar is difficult to accurate fixation；Cylinder unit is most to accord with
Close to have in reinforcing bar and the form of concrete binding power distribution characteristics, cohesion test both domestic and external and use such a form, generally
Using steel and plastic cylindrical device, but how to ensure that reinforcing bar is accurately located at the difficulty that its center position is this device
Point.Current existing cylinder unit, using the PVC round tube of cutting as template, and reinforcing bar is carried out using bottom embedding inlay technique
Position is fixed, and reinforcing bar bottom is embedded in wooden template, and reinforcing bar top can not then be fixed, in concreting process, it is difficult to
Ensure that reinforcing bar is in the center of cylinder；Also have using steel template, but test procedure is cumbersome, while also not economical enough.More than
Method is difficult to meet the need for disposable a large amount of test specimens pour, therefore needs badly using new equipment to solve this problem.
The content of the invention
The purpose of this utility model is that providing a kind of steel reinforced concrete tests bar reinforcement positioning device, is mainly used in civil engineering test
Middle armored concrete bond-slip properties experiment, the device can be effectively prevented from steel during casting concrete by gag lever post
Muscle moves problem, so as to greatly increase the accuracy of experiment, has advantageously accounted for reinforcing bar during researcher experiment eccentric
Problem.
A kind of steel reinforced concrete tests bar reinforcement positioning device, is that, by gag lever post, reinforced hole, outer wall, rubber ring and screw are constituted, its
It is characterised by that gag lever post is used with reinforced hole to be welded to connect, rubber ring is fixed on outer wall by screw.
As an improvement, the device is provided with a reinforced hole, and it is divided into 20mm, 22mm diameter Type different with 25mm.
As an improvement, the device is provided with 8 gag lever posts, gag lever post is processed using a diameter of 4mm plain bar.
As an improvement, rubber ring is fixed on the outer wall of the device by four screws；
As an improvement, the size of outer wall can make corresponding change according to experiment demand.
The beneficial effects of the utility model：A kind of steel reinforced concrete experiment bar reinforcement positioning device is tested for armored concrete bond-slip
Aid, ensures that reinforcing bar is in test specimen centre bit before and after concrete sample is poured using the cooperation of gag lever post and reinforced hole
Put；Casting concrete can be by the space in the gag lever post of top, it is ensured that the one-shot forming of test specimen, reduces the error of experiment.
To better meet scientific research personnel's experimental implementation demand, reinforced hole can make corresponding change according to the reinforcing bar of different-diameter.

Plain bar, and its two ends is welded with outer wall with reinforced hole respectively；Rubber ring is fixed followed by four screws
In the bottom of device.Finally this device is verified, the reinforcing bar for experiment is put into device check whether it is qualified.
A kind of steel reinforced concrete tests bar reinforcement positioning device, is that, by gag lever post, reinforced hole, outer wall, rubber ring and screw are constituted, its
It is characterised by that gag lever post is used with reinforced hole to be welded to connect, rubber ring is fixed on outer wall by screw.
As an improvement, the device is provided with a reinforced hole, and it is divided into 20mm, 22mm diameter Type different with 25mm.
As an improvement, the device is provided with 8 gag lever posts, gag lever post is processed using a diameter of 4mm plain bar.
As an improvement, rubber ring is fixed on the outer wall of the device by four screws；
As an improvement, the size of outer wall can make corresponding change according to experiment demand.
