Below will describe each embodiment of concrete-bar component, it comprises reinforcing bar 10 and reinforced concrete structure, and reinforced concrete structure has the concrete-bar component being embedded in wherein.In an embodiment, use the reinforcing bar label 10 that is added with capitalization English letter of reinforcing bar 10 to represent.
Fig. 2 to 4 shows the reinforced concrete post 21 (the linear reinforced concrete structure extending) according to first embodiment of the invention.Post 21 comprises concrete 22 and the linear concrete-bar component 23 that extends and be embedded in the cage type in concrete 22 with four jiaos of shape of cross sections.As everyone knows, post 21 obtains by concrete 22 being cast in the space of template (not shown) inside, template there are four jiaos of shape of cross sections and in factory or job site around concrete-bar component 23.
Concrete-bar component 23 comprises four vertical main muscle 24 and multiple hoop 10A (shear reinforcement).Main muscle 24 lays respectively at the bight place of the quadrangle shape of concrete-bar component 23, and is parallel to each other.Hoop 10A along longitudinal side of main muscle 24 at uniform intervals to arranging.
The common notched bars with longitudinal rib and cross rib can be with the muscle 24 of deciding.Alternately, there is the available muscle 24 of deciding of reinforcing bar (indented bars) of thread-shaped node (thread-shaped nods).
For example, hoop 10A can be described as welded closure hoop.There is the straight reinforcing bar 10 of shape of cross section of flattening by bending to form quadrangular plan shape and by the end opposite of welded reinforcement 10, can obtain hoop 10A.In Fig. 3, weld part is represented by label 10a, and angle of bend is represented by label 10b.Hoop 10A is horizontally disposed with (being set to orthogonal crossing with main muscle 24).Four angle 10b of hoop 10A are set to be wrapped in around main muscle 24, contact the outside of main muscle 24.Thereby hoop 10A is around four main muscle 24 and be positioned at the outermost of concrete-bar component 23.Hoop 10A and the 24 use fine wire (not shown) combinations of main muscle.
Concrete 22 has quadrangular cross section shape, is similar to the flat shape of concrete-bar component 23.Concrete 22 comprises four smooth concrete surface 22a that are parallel to respectively the each side of hoop 10A.Distance between outer surface and the concrete surface 22a of tetra-sidepieces of hoop 10A is the overburden depth T of concrete 22.
As shown in Fig. 4 A and 4B, in the time forming hoop 10A, make reinforcing bar 10 bendings, make respect to one another this on minor axis directions X be positioned at inner side and outside to flat surfaces 11a, 11a, form thus angle 10b.Because the thickness of bending direction reduces by this way, bending needed load can reduce, and the reinforcing bar 10 radius of curvature bending to reduce easily.Especially, because this effects on surface 11a respect to one another, 11a on minor axis directions X are smooth (cross-sectional profiles of reinforcing bar 10 is included in line part respect to one another on minor axis directions X) in the present embodiment, reinforcing bar 10 can be bending in the situation that there is no distortion, and can obtain setting hoop 10A in one plane.
Make this effects on surface 11a respect to one another, 11a on minor axis directions X be positioned at inner side mentioned above and outside because reinforcing bar 10 is bent, the cross section minor axis directions X of the every side of hoop 10A is perpendicular to concrete surface 22a.Have the conventional reinforcing bar of same cross-sectional area of circular shape of cross section than use time, this allows the size Lx of hoop 10A in the direction that is orthogonal to concrete surface 22a to reduce.This allows concrete overburden depth T more to go deep into and the corresponding degree of depth reduced in size.
From different angles, corresponding to binding round the reduced in size of 10A, the cross sectional area of concrete 22 can reduce, and guarantees the overburden depth of regulation simultaneously.
From another angle, main muscle 24 can (deviating from the direction at Zhu21 center) be placed on outside, and the intensity of post 21 can be enhanced, and its detailed description will provide at hereinafter with reference Fig. 4 B.If used the conventional hoop 100 (being represented by imaginary line in Fig. 4 B) of being made by the reinforcing bar with circular cross-sectional shape, main muscle 104 should be positioned at the position being represented by imaginary line, to guarantee enough overburden depth T, this is because the size in the direction that is orthogonal to concrete surface 22a is larger, and the radius of curvature of angle 100b is larger.On the other hand, when the reinforcing bar 10 of shape of cross section with flattening is when as hoop 10A of the present invention, the size in the direction that is orthogonal to concrete surface 22a is less, and the radius of curvature of angle 10b is less.Therefore,, in the time that the cross sectional area of concrete 22 is identical with overburden depth T, main muscle 24 can be positioned at main muscle outside of conventional hoop.
From another angle, for the cross sectional area that reduces concrete 22 is guaranteed concrete overburden depth simultaneously, or for outwards mobile main muscle 104 in the conventional hoop 100 with circular cross-sectional shape, the radius of hoop 100 should reduce.This can cause the minimizing of hoop 100 cross sectional areas.In order to compensate the minimizing of hoop 100 cross sectional areas, hoop 100 number should increase and bind round 100 spacing and should reduce.On the other hand, in the present invention, in the time that the cross sectional area of concrete 22 reduces or in the time that main muscle 24 outwards moves, concrete overburden depth can be guaranteed, without reducing the cross sectional area that binds round 10A.As a result, do not need to reduce the spacing of hoop 10A, thereby can not cause concrete filler deficiency.
Other embodiments of the invention below will be described.In these embodiments, represented by identical label corresponding to the parts of previous embodiment, and its detailed description will be omitted.
According in the post 21 of the second embodiment shown in Fig. 5, by bending but not bringing on the contrary of welded reinforcement 10 form hook portion 10c (catching portion) and by hook hook portion 10c a main muscle 24 around, can obtain and bind round 10B.As the first embodiment, angle 10b and the hook portion 10c of hoop 10B are bent, and make this effects on surface 11a respect to one another, 11a on minor axis directions X be positioned at inner side and outside.
According in the post 21 of the 3rd embodiment shown in Fig. 6, except being positioned at the main muscle 24 at the concrete-bar component 23 each angle of quadrangle shape places, middle main muscle 25 is arranged on the sidepiece of quadrangle shape.In the middle of shear reinforcement 10C strides across, main muscle 25 is laid.Particularly, hook portion 10d is formed on the opposite ends place of shear reinforcement 10C, and hook portion 10d is hooked around the main muscle 25 in centre.As hoop 10A, shear reinforcement 10C is made up of the reinforcing bar 10 of the shape of cross section with flattening.Make on minor axis directions X surfaces opposite to each other be positioned at inner side and outside forms hook portion 10d by moment reinforcement 10.Therefore, shear reinforcement 10C can outwards not protrude from hoop 10A, and can not cause the overburden depth of concrete 22 to reduce.
In the 4th embodiment shown in Fig. 7 and 8, the present invention is applied to the horizontally extending reinforced concrete beam 31 of linear mode (reinforced concrete structure).Have and the concrete-bar component 33 of the concrete-bar component 23 similar basic structures of post 21 by connection, and the concrete-bar component being connected 33 is embedded in the concrete 32 with quadrangular cross section shape, can obtain beam 31.The end that is arranged in two main muscle 34 on straight line is inserted in joint 35 and connects thus, thus in conjunction with going out concrete-bar component 33.In the time that main muscle 34 is indented bars, all female joints 35 end of main muscle 34 that can be used for being threaded in it.
Hoop 36 around main muscle 34 has circular cross-sectional shape, as conventional reinforcing bar.In order to maintain the intensity of beam 31, need to stride across joint 35 and lay hoop 10D (additional shear reinforcement).Because the radius of joint 35 is greater than the radius of main muscle 34, if the reinforcing bar with the circular cross section that is similar to hoop 36 is as binding round 10D, the concrete overburden depth T binding round between 10D and concrete surface 32a can reduce.For fear of the minimizing of such overburden depth, there is the reinforcing bar 10 of the cross section flattening shown in Fig. 1 as the hoop 10D in the present embodiment.The minor axis X of reinforcing bar 10 is orthogonal to concrete surface 32a, and is bent and makes this effects on surface 11a respect to one another, 11a on minor axis directions X be positioned at inner side and outside as previous embodiment reinforcing bar 10.Therefore, the minimizing of overburden depth T can be avoided.
From another angle, do not need the cross sectional area that reduces hoop 10D to guarantee overburden depth T.Further, do not need to increase the number of hoop 10D and reduce the spacing of binding round 10D with the minimizing of compensation hoop 10D cross sectional area.Particularly, hoop 10D can be to arrange with hoop 36 roughly the same spacing.
In the 4th embodiment, hoop 36 also can be made up of the reinforcing bar 10 of the shape of cross section with flattening.
Can be applied to the horizontally extending beam of linear mode according to the feature of the first post to the 3rd embodiment.
On the contrary, can be applied to post according to the feature of the beam of the 4th embodiment.
In the 5th embodiment shown in Fig. 9, the present invention is applied to reinforced concrete wall 41 (reinforced concrete structure extending with planar fashion).Wall 41 comprises two concrete-bar components 43 that are embedded in concrete 42.Concrete 42 comprises the vertical surperficial 42a being parallel to each other.Two concrete-bar components 43 are parallel to concrete surface 42a and are separately positioned in two planes that are spaced apart from each other along concrete 42 thickness directions.

The reinforcing bar 10 with the shape of cross section of flattening is used as vertical bar 10E and horizontal bar 10F.Reinforcing bar 10 is cut into predetermined size, and there is no bending straight structure for it.Reinforcing bar 10 is oriented as and makes the minor axis X of reinforcing bar 10 cross sections be orthogonal to concrete surface 42a.
Thus, the thickness of wall 42 can reduce, and guarantees concrete overburden depth T simultaneously and guarantees that the filler concrete between concrete-bar component 43 has sufficient space.From another angle, concrete overburden depth T can increase, or can increase for the concrete space of filler, without the thickness that changes wall 42.
In the 6th embodiment shown in Figure 10 and 11, the present invention is applied to the reinforced concrete wall 41 of embodiment as shown in Figure 9.Be formed on wall 41 for the opening 41a that the (not shown) such as pipe are set therein.In the area corresponding to opening 41a, remove vertical bar 10E and the horizontal bar 10F of concrete-bar component.Opening 41a can be the opening of window or door.

The merging of diagonal angle muscle 10G can reduce concrete overburden depth or this is to the filler concrete space between concrete-bar component 43.But, there is the reinforcing bar 10 of the shape of cross section of flattening by employing, can comprise such minimizing.
