Background
The reinforcing steel bar is widely applied in the field of civil engineering, mainly bears the tensile force in a reinforced concrete structure, and cooperatively bears various load forms of pulling, pressing, bending, shearing, twisting and the like of the structure together with concrete. The reinforced concrete structure has good bearing capacity, but for an overlong structure, the concrete may be cracked due to large tensile force generated in the structure under the action of concrete shrinkage creep or temperature, and the safety of the structure and the comfort under normal use may be influenced.
The shrinkage behavior of a concrete structure is greatly influenced by the structure, the larger the plane size of the structure is, the stronger the constraint at the periphery of the structure is, and the larger the temperature stress generated in the structure is, the more easily the concrete structure is cracked. Such cracks affect the visual sense of people, causing discomfort, while environmental factors more easily cause deterioration of internal concrete or reinforcing bars through cracks, thereby affecting the safety or durability of the structure.
With the development of society, the demand of large public buildings is rapidly increased, and the size of the structural plane is continuously increased. In order to reduce the influence of temperature stress, the traditional mode is that the structure plane is divided into regular smaller sizes by arranging expansion joints, each block structure expands and contracts in respective small-scale range, and the caused temperature stress is small, but the following defects exist:
(1) the wall types such as retaining walls and the like need to be continuously arranged and cannot be subjected to joint separation;
(2) the expansion joint part needs special building treatment, which affects the use and the appearance;
therefore, the engineering industry tends to avoid the seam, and only uniform, fine and dense cracks are ensured to appear through reasonable reinforcement, design reinforcing methods such as micro-expansion concrete or prestress application and construction measures such as reinforcing maintenance, or the cracks are only formed at the parts with small influence on vision and use through the measures of inducing the seams, so that the concentrated treatment is convenient. However, the traditional induced joint structure is complex, additional steel bars need to be arranged, and construction is inconvenient.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Example one
Referring to fig. 1 to 8, the present embodiment provides a reinforced concrete wall induced joint structure with S-shaped bent steel bars, which includes: the concrete wall body 102, the wall body vertical reinforcing steel layer 103 and the S-shaped bending reinforcing steel layer 101; the wall vertical reinforcing steel bar layer 103 is vertically arranged in the concrete wall 102; the S-shaped bending reinforcing steel bar layer 101 is horizontally arranged in the concrete wall 102, and the S-shaped bending reinforcing steel bar layer 101 replaces the traditional non-dislocation horizontal reinforcing steel bars in the wall in whole or part; the reinforcing steel bar of the S-shaped bent reinforcing steel bar layer 101 includes: the steel bar body is provided with at least two straight line steel bar sections 2 and at least one oblique line steel bar section 1; the first end of the oblique line steel bar section 1 is connected with the adjacent first straight line steel bar section 21; the second end of the oblique line steel bar section 1 is connected with the adjacent second straight line steel bar section 22; the first linear steel bar section 21 and the second linear steel bar section 22 are distributed in a staggered relation; the concrete wall 102 forms a concrete structure weakening section 104 at the position corresponding to the dislocation position of the S-shaped bending reinforcing steel bar layer 101.
The S-shaped bent reinforcing steel bars are arranged in the wall body, when the wall body is pulled, the wall body at the reinforcing steel bar dislocation part is weaker than the wall body at the reinforcing steel bar non-dislocation part, so that the wall body is deformed and concentrated at the reinforcing steel bar dislocation part, and the wall body at the reinforcing steel bar non-dislocation part is prevented from generating temperature cracks.
In this embodiment, the arrangement of the S-shaped bent steel bars inside the concrete wall 102 may be flexibly arranged according to actual needs.
Preferably, one or more layers of S-shaped bending reinforcing steel bar layers 101 are arranged in the concrete wall 102 from top to bottom; one or more rows of S-shaped bent steel bars are arranged on the same S-shaped bent steel bar layer 101. Preferably, in each S-shaped bending steel bar layer 101, the diagonal steel bar section 1 of each steel bar layer is correspondingly arranged.
For example: the S-shaped bent steel bar layer 101 can be divided into an inner steel bar layer and an outer steel bar layer, and for a thicker wall, from one steel bar layer to a plurality of steel bar layers are arranged in the middle. Optionally, each group of S-shaped bent steel bar layers 101 includes steel bar bent oblique sections arranged at corresponding positions of the steel bar layers inside and outside the wall and in the middle of the wall, so as to obtain the best deformation capability of the wall; the steel bar bending inclined section can be arranged at the corresponding position of the inner and outer steel bar layers to simplify the construction, but the steel bar bending inclined section is not limited to the construction, and can also be arranged at other layers. In the same S-shaped bent steel bar layer 101, the diagonal steel bar sections 1 of the steel bars in each row are correspondingly arranged. That is to say, the dislocation directions of the S-shaped bent reinforcing steel bars in each row of the same layer are consistent, and the dislocation directions of the S-shaped bent reinforcing steel bars in different layers are consistent, so that uniform stress is realized, and construction is simplified.
For example: the left straight-line segment of each layer of S-shaped bent steel bars is higher than the right straight-line segment, namely the oblique segment is in the upper left-lower right direction, or the dislocation direction of each layer and each row of S-shaped bent steel bars in the same layer is opposite to the dislocation direction.
Preferably, the concrete wall 102 is provided with a single-sided or double-sided groove at the offset position of the S-shaped bending reinforcing steel bar layer 101 to form a concrete structure weakening section. The shape of the section of the groove includes, but is not limited to, a square, a rectangle, a triangle, a circular arc or other curved shapes, and the main purpose is to make the wall area at the diagonal section in the S-shaped bending reinforcement layer 101 slightly smaller than the straight line section, so as to ensure that the grooved part is cracked before the non-grooved part in the tensile deformation process of the concrete wall 102. After the concrete wall 102 is cracked at the groove, the S-shaped bent reinforcing steel bar layer 101 is gradually straightened at the same section position without generating obvious stress increase in the reinforcing steel bars, the reinforcing steel bars are prevented from being damaged, and even after the reinforcing steel bars are nearly straightened, the bearing capacity of the reinforcing steel bars is improved to a certain extent. Therefore, the purpose that the wall body deforms without reducing the bearing capacity of the wall body is achieved, and the deformable reinforced concrete wall body structure is formed.
Preferably, the concrete wall 102 is provided with a water stop structure at the position of the offset of the S-shaped bending reinforcing steel layer 101. For example: water stopping measures such as water stopping steel plates or water stopping strips (tapes), sealant (located at the grooves) and the like need to be arranged outside and/or inside the concrete wall 102 at the positions corresponding to the oblique line sections of the S-shaped bent reinforcing steel bars, so that after the concrete wall 102 is cracked, a water body passage is separated by various water stopping measures, and the influence on the use or the wall safety is avoided.
The embodiment can be used for temperature induced seam processing of overlong reinforced concrete wall structures such as basement retaining walls, parapet flanges and outdoor cantilever slabs. The horizontal reinforcing bar atress of conventional basement retaining wall, parapet turn-ups and outdoor board of encorbelmenting is less, and its main effect does not influence overall structure atress for coordinating vertical reinforcing bar atress and reducing the concrete crack even the concrete is in establishing seam department fracture when induction seam fully developed. More broadly, the person skilled in the art can also refer to the patent to perform the construction treatment on the non-main stress direction steel bars of other reinforced concrete wall structures to obtain the deformation capability.

Therefore, smooth transition is realized between the oblique line steel bar section 1 and the first straight line steel bar section 21 and between the oblique line steel bar section 1 and the second straight line steel bar section 22, and the deformability of the steel bars can be effectively improved.
Of course, it should be noted that the sizes of the oblique straight line segment, the first transition segment 11 and the second transition segment 12 can be flexibly set according to actual needs.

The diagonal reinforcement section 1 includes: a first diagonal line segment and a second diagonal line segment; the first end of the first oblique straight line section is connected with the first straight steel bar section 21 through the first transition section 11; the second end of the first inclined straight line section is connected with the first end of the second inclined straight line section; the second end of the second diagonal segment is connected to the second straight rebar segment 22 through a second transition segment 12. The slopes of the first oblique straight line segment and the second oblique straight line segment are different, so that the first straight steel bar segment 21 and the second straight steel bar segment 22 are distributed in a staggered relation.
Another example is: the first transition section 11 and the second transition section 12 are arc transition sections, and the tops of the arcs are concave to form two-stage transition subsections.

EXAMPLE six
With reference to fig. 9 to 10, a sixth embodiment provides a technical solution of the spacer 105 configured on the basis of the first, second, third, fourth and fifth embodiments, and the technical features disclosed in the first, second, third, fourth and fifth embodiments are also applicable to the sixth embodiment, and the same technical features are not repeated and only differences are described below.
For example: the S-shaped bent steel bar is sleeved with an isolation sleeve 105 at the dislocation position so as to isolate the dislocation section from the concrete. It can be understood that the S-shaped bent reinforcing steel bars are positioned at the staggered section which is the diagonal reinforcing steel bar section.
In a preferred embodiment, the whole dislocation section is accommodated in the corresponding isolation sleeve 105, in other words, the isolation sleeve 105 completely covers the "dislocation" part, so that the isolation sleeve 105 can effectively isolate the dislocation section from concrete, and the dislocation section can be sufficiently deformed when the wall body is pulled due to temperature change.
In some embodiments, the isolation sleeve 105 may be sleeve-shaped, for example, may be a square sleeve, may be an oval sleeve, but is not limited thereto.
In some embodiments, the insulation sleeve 105 may be a rigid or flexible material such as, but not limited to, FRP, wood, foam, polystyrene board, rubber, and the like.
In some embodiments, the insulation sleeve 105 may be an FRP (fiber reinforced polymer/plastic, FRP) insulation sleeve 105. The FRP isolation sleeve 105 can be formed by compounding fibers and a matrix through a certain process, and has the excellent characteristics of light weight, high strength, corrosion resistance and the like.

In some embodiments, the two ends of the isolation sleeve 105 may be sealed, on one hand, when concrete is poured, the concrete is prevented from entering the gap between the "S-shaped steel bar" dislocation section and the isolation sleeve 105, so as to facilitate the free expansion and contraction of the "S-shaped steel bar" and the release deformation of the concrete wall structure; on the other hand, the spacer 105 can be easily fixed to the S-shaped reinforcing bars. Such as sealing structure 106, which can be tied with a tether or a steel wire at the end of the soft isolation sleeve 105; such as the sealing structure 106, is filled with sealant, wood chips, foam, etc. at the end of the rigid insulating sleeve 105. However, the sealing treatment is not limited to this.
In summary, according to the reinforcement assembly of the embodiment of the invention, the isolation sleeve 105 for isolating concrete is arranged at the "dislocation" position of the S-shaped reinforcement, so that the "dislocation" position can be sufficiently stretched when being subjected to a large external force, the deformation capability is ensured, a large local stress caused by the direct contact between the "dislocation" position and the concrete can be avoided, and the local damage of the concrete is avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
