Abstract
The invention discloses a notch-type steel reinforced concrete structure. The notch-type steel reinforced concrete structure comprises H-section steel and concrete externally wrapping the H-section steel, wherein the H-section steel comprises a web plate and two flange plates which are located at the two sides of the web plate; notches are formed in the edges of the flange plates to increase a mechanical engagement force, a friction force and an adhesion force between the section steel and the concrete. According to the notch-type steel reinforced concrete structure disclosed by the invention, a high force transfer effect is acted between the concrete and the section steel, so that a relative slide generated between steel ribs and the concrete under a load effect can be reduced.
Description
Technical field
The present invention relates to building implements technical field, particularly relate to a kind of gap type steel reinforced concrete structure.
Background technology
Steel reinforced concrete structure is the one independently form of structure of arranging that in concrete component shaped steel gained arrives.Owing to adding shaped steel in steel concrete, shaped steel improves the strength and ductility performance of concrete structure greatly with its intrinsic strength and ductility.Compared with traditional reinforced concrete structure, shaped steel and concrete collaborative work steel reinforced concrete structure is possessed bearing capacity is large, rigidity is large, anti-seismic performance is good advantage.
Because steel reinforced concrete intensity is high, thus structure or member designs load large.Generally power transmission is carried out by splicing power between the two, frictional resistance and mechanical snap power between reinforcing bar and concrete.But for existing steel reinforced concrete structure, the intermal force between reinforcing bar and concrete is more weak on the whole.When load is larger, need between shaped steel reinforcing bar and concrete to transmit larger internal force, now, often can produce the larger Relative sliding between reinforcing bar and concrete.This Relative sliding has a negative impact to the strength performance of steel reinforced concrete structure to a certain extent.
Summary of the invention
Main purpose of the present invention is to provide a kind of gap type steel reinforced concrete structure, is intended to reduce the Relative sliding produced between reinforcing bar and concrete.
For achieving the above object, the invention provides a kind of gap type steel reinforced concrete structure, comprise H profile steel and be wrapped in the concrete outside this H profile steel, wherein, described H profile steel comprises web and is positioned at two blocks of frange plates of these web both sides, has breach to improve mechanical snap power, frictional force and the bond between shaped steel and concrete at the edge of described frange plate.
Preferably, the edge of two blocks of frange plates of described H profile steel longitudinally has multiple breach, and breach is longitudinally regularly arranged.
Preferably, the edge of the end of two blocks of frange plates of described H profile steel transversely has multiple breach, and breach is transversely regularly arranged.
Preferably, the breach of described frange plate is semicircular indentations.
The gap type steel reinforced concrete structure that the present invention proposes has following beneficial effect:
1, due to the frange plate edge breach longitudinally of shaped steel, the mechanical snap power between type Steel concrete is significantly increased, along the component longitudinally comparatively raw slippage of difficult labour, overall performance good between guarantee type Steel concrete.
2, due to the frange plate edge breach longitudinally of shaped steel, contact area between type Steel concrete is increased, and splicing power and frictional resistance also strengthen, and are conducive to the slippage between control type Steel concrete.
3, due to section steel flange panel edges breach transversely, the mechanical snap power transversely between type Steel concrete is significantly increased, along the component laterally comparatively raw slippage of difficult labour, and overall performance good between guarantee type Steel concrete.
4, due to frange plate edge, shaped steel end breach transversely, horizontal bond and frictional resistance are also improved.
5, because aperture area is limited, less on the impact of shaped steel intensity.In the design stage by the rational Choice and design in shaped steel cross section, opening can be avoided the impact of shaped steel intensity.
6, the opening of shaped steel section edges can provide the effect of firm hanging belt when lifting shaped steel.
7, the technique of shaped steel opening is simple, and cost is low, and the gap type steel reinforced concrete structure cost performance that the present invention proposes is high.

Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
It should be noted that, in describing the invention, term " transverse direction ", " longitudinal direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, be not indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
Referring to figs. 1 through Fig. 3, in this preferred embodiment, gap type steel reinforced concrete structure, comprise H profile steel and be wrapped in the concrete 4 outside this H profile steel, wherein, H profile steel comprises web 2 and is positioned at two blocks of frange plates 1 of these web 2 both sides, has breach 3 to improve mechanical snap power, frictional force and the bond between shaped steel and concrete 4 at the edge of frange plate 1.
Particularly, in the present embodiment, the edge of two blocks of frange plates 1 of H profile steel longitudinally (being longitudinally the direction parallel with web 2) has multiple breach 3, and breach 3 is longitudinally regularly arranged.The edge of the end of two blocks of frange plates 1 of H profile steel transversely (being laterally the direction vertical with web 2) has multiple breach 3, and breach 3 is transversely regularly arranged.
In the present embodiment, the breach 3 of frange plate 1 is preferably semicircular indentations.Certainly, in other variant embodiment, breach 3 also can be awave (with reference to Fig. 4).
The gap type steel reinforced concrete structure that the present invention proposes has following beneficial effect:
1, due to the frange plate 1 edge breach 3 longitudinally of shaped steel, the mechanical snap power between type Steel concrete 4 is significantly increased, along the component longitudinally comparatively raw slippage of difficult labour, overall performance good between guarantee type Steel concrete 4.
2, due to the frange plate 1 edge breach 3 longitudinally of shaped steel, contact area between type Steel concrete 4 is increased, and splicing power and frictional resistance also strengthen, and are conducive to the slippage between control type Steel concrete 4.
3, due to shaped steel flange plate 1 edge breach 3 transversely, the mechanical snap power transversely between type Steel concrete 4 is significantly increased, along the component laterally comparatively raw slippage of difficult labour, and overall performance good between guarantee type Steel concrete 4.
