Abstract
The utility model relates to an anti-crack strip for cement, which is made into a short strip shape by steel, and both ends of the anti-crack strip are provided with protrusions or concave convex combined objects. A proper amount of anti-crack strips are filled in the cement in the course of construction, the stretching resistance of the cement can be increased, and thereby, the crack of a building can be avoided.
Description
The utility model relates to a kind of cement Anti-crack strip.
The reinforcing bar girder steel is not resistance to compression of tension, and cement is not tension of resistance to compression, and therefore the thing that this two specific character is different adds together, and becomes the indispensable material of building today.Yet reinforcing bar all is the centre that is placed on cement beam column or other structure at present, therefore at distance reinforcing bar or girder steel cement far away because of lacking the power-assisted of reinforcing bar or girder steel tension, easily be full of cracks, and As time goes on slight crack splits wideer and wideer, long more, quite big to the destruction of building.
The purpose of this utility model designs a kind of cement Anti-crack strip at above-mentioned defective exactly, and this blending is in cement and stir the back construction therewith, in case after theing cement solidifies, this can increase the stretching resistance of cement.
The purpose of this utility model is achieved through the following technical solutions: the utility model is that steel are made short strip shape, is respectively equipped with the object of protrusion outside bar at this two ends, or the concavo-convex object that combines.
The object cross sectional shape of protrusion outside bar can be sphere, wooden club shape, square, dish type, ellipse or other shape.
The concavo-convex body surface that combines is shape of threads, or integral body shape, wavy or surperficially be provided with some grooves vertically in the shape of a spiral.
Technical characterstic of the present utility model and result of use:
1, simple in structure, be easy to make, and with low cost;
2, in cement, add an amount of Anti-crack strip, the back construction that stirs, after cement was done admittedly, these two ends formed two or more origin of force, can increase the omnibearing stretching resistance of cement.Especially being fit to aspects such as bridge, fortification or nuclear facilities uses.
Accompanying drawing and description of drawings:
Accompanying drawing 1 is that two ends are the Anti-crack strip schematic diagram of helical form object, and 1 is helix, the 2nd among the figure, the bar body.
Accompanying drawing 2 is that two ends are the Anti-crack strip schematic diagram of sphere, and 3 is spheres among the figure.
Accompanying drawing 3 is that two ends are the Anti-crack strip schematic diagram of pan, and 4 is pans among the figure.
Accompanying drawing 4 is that two ends are the Anti-crack strip schematic diagram of shape of threads thing, and 5 is shape of threads things among the figure.
Accompanying drawing 5 is that two ends are the Anti-crack strip schematic diagram of wavy thing, and 6 is wavy things among the figure.
Claims (4)
1, a kind of cement Anti-crack strip is characterized in that this two ends are respectively equipped with the object of protrusion outside bar, or the concavo-convex object that combines.
2, the cement Anti-crack strip of narrating according to claim 1, the cross sectional shape that it is characterized in that protruding the object outside bar are sphere, wooden club shape, square, dish type, ellipse or other shape.
3, the cement Anti-crack strip of narrating according to claim 1 is characterized in that the concavo-convex body surface that combines is a shape of threads, or integral body shape, wavy in the shape of a spiral, or body surface is provided with several trough vertically.
4,, it is characterized in that this is made by steel according to claim 1 or the 2 or 3 cement Anti-crack strips of being narrated.
