Abstract
The utility model discloses a kind of reinforced concrete structure distributed anchoring and muscle, comprise and be located at steel concrete and original state reinforcing bar in rib component and concrete anchorage element and dispersion reinforcing bar, described original state reinforcing bar comprises and muscle horizontal segment and the also vertical section of muscle, described dispersion reinforcing bar comprises and muscle horizontal segment, and muscle bending segment and the also vertical section of muscle, described original state reinforcing bar and dispersion reinforcing bar they and muscle horizontal segment be close together and be located at described steel concrete and in rib component, the also vertical section of muscle of described original state reinforcing bar is located in described concrete anchorage element with the shape and muscle bending segment and the also vertical segment components of muscle fall apart of dispersion reinforcing bar.The utility model can make in concrete anchorage element two reinforcing bar external surfaces be bonded by concrete completely, realizes, with concrete well-bonded, can reducing anchorage length, reaches the object of saving reinforcing bar.
Description
Technical field
The utility model belongs to reinforced concrete member steel bar stress anchoring field, is specifically related to a kind of reinforced concrete structure distributed anchoring and muscle.
Background technology
Along with superelevation, greatly across a large amount of appearance of the conditions such as, heavy duty, generally there is large-scale beam, post component in building, when component adopts steel concrete, often occur the situation that arrangement of reinforcement is intensive or reinforcing bar is excessively thick.For solving bar reinforcement and the intensive difficulty causing design, construction of arrangement of reinforcement, " Code for design of concrete structures " (GB 50010-2010) proposes steel bar stress and can adopt and the arrangement of muscle, especially the arrangement of reinforcement close quarters of beam, as shown in Figure 1, and two of muscle reinforcing bars 1 comprise be located at steel concrete and in rib component a and muscle horizontal segment 101 and be located in concrete anchorage element b and the vertical section 102 of muscle.Reinforcing bar and concrete adhesion stress by reinforcing bar the surface area that bonds by concrete determine, not and muscle time single steel bar concrete bond external surface and just equal its reinforcing bar external surface in concrete, due to and after muscle the concrete of two reinforcing bars 1 bond external surface c(and see Fig. 2) be less than two reinforcing bar 1 external surface sums, and after muscle during same length single steel bar and concrete adhesion stress comparatively and muscle before decline, so and muscle after reinforcing bar anchorage length comparatively the increase of single steel bar anchorage length just can reach anchored force standard, its specific practice is: and muscle calculates by single equivalent reinforcing bar, the equivalent diameter of equivalence reinforcing bar converts by the principle that section area is equal and determines.Convert according to equivalent diameter principle, and after muscle the anchorage length of steel bar stress more not and muscle time increase a lot, cause the increase of amount of reinforcement.
Utility model content
Anchorage length increases the amount of reinforcement caused and increases problem for steel bar stress and after muscle, and the purpose of this utility model is to provide a kind of reinforced concrete structure distributed anchoring and muscle, to reduce anchorage length, saves reinforcing bar.
The technical solution of the utility model is achieved in that
Reinforced concrete structure distributed anchoring muscle, comprise and be located at steel concrete and original state reinforcing bar in rib component and concrete anchorage element and dispersion reinforcing bar, described original state reinforcing bar comprises and muscle horizontal segment and the also vertical section of muscle, described dispersion reinforcing bar comprises and muscle horizontal segment, and muscle bending segment and the also vertical section of muscle, described original state reinforcing bar and dispersion reinforcing bar they and muscle horizontal segment be close together and be located at described steel concrete and in rib component, the also vertical section of muscle of described original state reinforcing bar is located in described concrete anchorage element with the shape and muscle bending segment and the also vertical segment components of muscle fall apart of dispersion reinforcing bar.
The beneficial effects of the utility model:
Distributed anchoring of the present utility model muscle adopt original state reinforcing bar and dispersion reinforcing bar, wherein original state reinforcing bar and dispersion reinforcing bar and muscle flat segments to be located at steel concrete and in rib component, and the also vertical section of muscle of original state reinforcing bar and the shape and muscle bending segment and the also vertical segment components of muscle fall apart of dispersion reinforcing bar are located in concrete anchorage element, in concrete anchorage element two reinforcing bar external surfaces are bonded by concrete completely, realize with concrete well-bonded, convert according to equivalent diameter principle, compared to existing and muscle can reduce anchorage length, reach the object of saving reinforcing bar.
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is existing anchoring muscle schematic diagram in reinforced concrete member.
Fig. 2 is in Fig. 1 and muscle sectional schematic diagram.
Fig. 3 is the utility model reinforced concrete structure distributed anchoring and muscle schematic diagram.
Detailed description of the invention
As shown in Figure 3, the utility model reinforced concrete structure distributed anchoring muscle, comprise and be located at steel concrete and original state reinforcing bar in rib component a and concrete anchorage element b 1 and dispersion reinforcing bar 1 ', described original state reinforcing bar 1 comprises and muscle horizontal segment 101 and the also vertical section 102 of muscle, described dispersion reinforcing bar 1 ' comprises and muscle horizontal segment 101 ', and muscle bending segment 103 ' and the also vertical section 102 ' of muscle, described original state reinforcing bar 1 and their also muscle horizontal segment 101 of dispersion reinforcing bar 1 ', 101 ' is close together side by side is located at described steel concrete and in rib component a, described original state reinforcing bar 1 and the vertical section of muscle 102 and dispersion reinforcing bar 1 ' and muscle bending segment 103 ' becomes dispersed to be located in described concrete anchorage element b with the also vertical section of muscle 102 '.
Due to original state reinforcing bar 1 and the vertical section of muscle 102 and dispersion reinforcing bar 1 ' and muscle bending segment 103 ' becomes dispersed to be located in described concrete anchorage element b with the also vertical section of muscle 102 ', they and the concrete length fully contacted to reduce anchor bar part can be realized, reach the effect of saving reinforcing bar.
