Description

A kind of carbon cloth fixture of concrete simple shear test
Technical field
The utility model is related to concrete construction field, more particularly to a kind of carbon fiber cloth clamp of concrete simple shear test Tool.
Background technology
At present, carbon cloth (CFRP hereafter substitutes carbon cloth with CFRP) folder in known concrete simple shear test Tool design, it is mostly in the majority with horizontal direction simple shear test, and fixture simple coarse, have small between chuck-CFRP in loading procedure Displacement, loading procedure is unstable, as a result discrete.
The content of the invention
In order to overcome simple shear test mostly can only level to operation, and this condition limitation under load equipment it is simply thick Rough, the inadequate shortcoming of precision, the utility model provides a kind of CFRP fixtures of confession vertical direction operation, and the fixture can not only be by original The level behaviour for coming is vertically operating, and can be used with pulling force sensor, ball pivot connection, it is ensured that vertical tension is accurate, and examination Test result stable, accurate.
The problem that the utility model is solved is to provide a kind of carbon cloth fixture of simple shear test on coagulation.
In order to solve the above technical problems, the technical scheme that the utility model is used is:
A kind of carbon cloth fixture of concrete simple shear test, including jig main body, its characteristic are have body upper surface Ball pivot is installed, lower logical recess is provided with inside jig main body, be provided with recess two pieces of centres with certain gap and side by side The steel clamp plate of arrangement, is provided with several high-strength bolts to force in a pair of clamping plates, jig main body side on jig main body side Two ends are provided with the stove bolt for positioning clamping plate, and aluminium flake is strengthened in the CFRP ends that soft material is accompanied between a pair of clamping plates.
The jig main body is box hat housing.
The steel clamp plate is provided with scale.
Strengthen aluminium flake in the CFRP ends for thering is indentation one side to clamp soft material on the steel clamp plate.
The beneficial effects of the utility model are:Compared with prior art, the carbon cloth fixture of concrete simple shear test, reaches The effect of fiber cloth is anchored to preloading, experiment and scientific research link medial end portions at the construction field (site), the utility model can solve fibre There is micro-displacement between dimension cloth loading area chuck-CFRP, loading procedure is unstable, the discrete serious problem of data result.
Simple structure & low cost of manufactures & & easy to operate save human cost --- and-whole fixture cost is in 800 yuan of people People's coin or so a, workman can be easily accomplished operation.
The whole fixture of time saving accurate & stabilizations --- -- of the efficient & of & can be used with pulling force sensor, ball pivot connection, be realized Vertical tension is accurate, high efficiency and time conservation, and result of the test is stable, accurate.

Specific embodiment
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
A kind of carbon cloth fixture of concrete simple shear test, including jig main body 1, its characteristic are have main body upper table Face is provided with ball pivot, and lower logical recess is provided with inside jig main body, and two pieces of centres are provided with recess with certain gap and simultaneously The steel clamp plate of arrangement is arranged, several high-strength bolts are installed on jig main body side to force in a pair of clamping plates, jig main body side Face two ends are provided with the stove bolt for positioning clamping plate, and aluminium flake is strengthened in the CFRP ends that soft material is accompanied between a pair of clamping plates.
The jig main body is box hat housing.
The steel clamp plate is provided with scale.
Strengthen aluminium flake in the CFRP ends for thering is indentation one side to clamp soft material on the steel clamp plate.
Economic benefit forecast:
Because this product is in the case where manufacturing cost is relatively low, the stabilization of concrete simple shear test data is significantly lifted Property, reliability, and then protect test specimen to be tested.By taking 30 block concretes (1m fiber cloths) simple shear test as an example, prior art Level occurs that frequent wire drawing, chuck such as can't clip at the bad trystate in operation.According to experiment experience, 40% is there are about Experiment test specimen turn into useless part, direct economic loss reaches 40%.And the utility model fixture is used, experiment number is ensure that first According to stabilization, reliability, in addition on the protective rate of test specimen, also have and significantly lifted, through budget, cost of labor can be saved about 40%, test material cost can save about 40%, and loading mechanical loss saves about 40%, and economic benefit is good.
The embodiment that the utility model is created has been described in detail above, but the content is only the utility model wound The preferred embodiment made, it is impossible to be considered as limiting practical range of the present utility model.It is all to create scope according to the utility model The impartial change made and improvement etc., all should still belong within this patent covering scope.
