Abstract
The utility model relates to a special-shaped section for the construction, which improves disk-circular steel sections for the construction always used by people. The original cylindrical circular section is changed into an ellipse, a triangle and a rectangle and is rotated along the direction of length, and therefore, the cylindrical shape is changed into a twist shape. After the improvement, the friction coefficient among the steel sections and concrete is increased by folds, and the strength of the precast concrete is increased by 30%. The construction quality is obviously changed, and the incidence rate of hazardous buildings is effectively reduced. The utility model is suitable for the foundation materials of various industrial and civil engineering and highways.
Description
The utility model is a kind of Special shape section for building, in concrete operation, plays the effect of strengthening concrete strength.
Reinforcing bar is in building industry, it has been the effect that increases concrete strength, and the intensity of concrete prefabricated element is relevant with the size and the frictional force of reinforcing steel area, the concrete component intensity of screw thread steel is better than the concrete component of common iron in the practical application, it is better that it removes material own, exactly since the frictional force that screw thread causes on the steel in action.
The purpose of this utility model is exactly the Special shape section for building that a kind of high frictional force will be provided, and it can not only make concrete intensity improve, and handling ease, and common iron can improve concrete strength more than 30% after processing.In the more advanced Japan of building industry, once to the dish round bar of different size in practical application, made detailed experiments, and its intensity of concrete component that report has the rust reinforcing bar to produce is better than the concrete component that unrusted reinforcing bar is produced, from the friction theory analysis, because of the rough surface of rust face, the result that frictional force causes greatly, the screw thread of screw-thread steel also is to strengthen frictional force, so as to having increased concrete intensity.Through processing, make friction coefficient surpass screw-thread steel as common iron, construction quality is improved, expense obtains reducing.
The purpose of this utility model is to realize like this, it is improved the wire rod rolled product for building that we continue to use always, original columniform circular section is changed into ellipse (4) by roll extrusion, triangle (5), four prismatics (6), and rotated along its length direction, make it from elliptical cylinder-shape, triangular prism, quadrangular is deformed into respectively: elliptical deformation is an oval fried dough twist cylindricality (1), triangular prism becomes triangular fried dough twist cylindricality (2), quadrangular becomes four rib fried dough twist cylindricalitys (3), after improving like this, profile shapes is the twisted shape circle, because of in various degree reduction the round covering of the fan of former circle, it reduces to some extent with the material amount, the surface also presents convex-concave clocklike simultaneously, friction between steel and the concrete becomes the spiral friction from planar friction, its coefficient of friction is multiplied, in the practice of construction operation, the distribution of invar muscle is to have in length and breadth, and this just can comprehensively increase the quality of armored concrete.Experiment showed, that the intensity that makes precast concrete increases more than 30 percent.
Owing to adopted the such scheme construction quality to have obvious change, effectively reduce the incidence of dangerous building, it is applicable to the civil engineering of various industry and people's industry, the ground material of highway.

Below be described in further detail in conjunction with the accompanying drawings for the utility model
As shown in the figure, it is that original columniform circular section is changed into ellipse (4) by roll extrusion, triangle (5), four prismatics (6), and rotated along its length direction, make it from elliptical cylinder-shape, triangular prism, quadrangular is deformed into respectively: elliptical deformation is an oval fried dough twist cylindricality (1), triangular prism becomes triangular fried dough twist cylindricality (2), quadrangular becomes four rib fried dough twist cylindricalitys (3), it is characterized in that, original column type is made it to change into cylindroid twist shape 1 by roll extrusion and rotation, triangular prism twist shape 2, quadrangular twist shape 3, three kinds of forms after the change, from cross-section, it is the twisted shape circle, because of in various degree reduction the round covering of the fan of former circle, it reduces to some extent with the material amount, the surface also presents convex-concave clocklike simultaneously, this feature just uses the vertical friction between steel and the concrete to become the spiral friction from planar friction, its coefficient of friction is multiplied, in the practice of construction operation, the distribution of invar muscle is to have in length and breadth, this just can comprehensively increase the quality of armored concrete, increases the service life of building.
Claims (1)
1 one kinds of Special shape section for building, be that wire rod rolled product for building changes elliptic cross-section by former columniform circular section into by roll extrusion, the triangular form cross section, four rib type cross sections, and vertically in addition improved, it is characterized in that: the circular section of original dish circle is changed into ellipse, triangle, four rib types vertically change the fried dough twist cylindricality again into.
