Description

Technical Field

[0001] The utility model relates to the technical field of wall structure construction, in particular to a reinforcing bar configuration structure of a construction column and a construction column. Background Art

[0002] A construction column is a vertical member arranged at the main corner parts of a wall body. Its function is to form a space framework together with a ring beam to improve the overall stiffness and overall ductility of a building, thereby restricting the development of wall cracks and increasing the seismic resistance of the building.

[0003] A construction column refers to a column arranged to enhance the integrity and stability of a building. The construction column includes a reinforced concrete construction column and a concrete construction column. A reinforced concrete construction column is a construction column with a steel bar framework added in concrete, which provides greater strength and bearing capacity and is commonly used in the walls of large buildings, high-rise buildings and multi-story brick-concrete structure buildings. For example, the reinforced concrete construction columns arranged in the walls of a multi-story brick-concrete structure building are connected to the ring beams of each floor to form a space frame that can resist bending and shear, which can effectively prevent the collapse of the house. In the walls of a multi-story brick-concrete structure building, construction columns are usually arranged at the four corners of the outer wall, the intersection of the transverse wall and the outer longitudinal wall at the staggered floor part, both sides of a larger opening, and the intersection of the inner and outer walls of a large room, etc.

[0004] In a reinforced concrete construction column, the configuration structure form has a greater impact on the stiffness and bearing capacity of the construction column. The existing reinforcing bar configuration structure of the construction column adopts post-inserted bars at both the upper end and the lower end of the construction column. As Figure 1 shown, the depth of the post-inserted bar takes the larger value of 10d and 100 mm, and a certain length is reserved for the post-inserted bar. The reserved length takes the larger value of 50d and 500 mm, and a full lap binding is adopted between the post-inserted bars at the upper end and the lower end and the reserved length of the post-inserted bar with a full-length steel bar. Then, stirrups are bound along the height direction of the construction column, and finally, the concrete of the construction column is poured to form a reinforced concrete construction column. However, this structural form and the formed construction column have the following problems:

[0005] Firstly, within the reserved length range of the post-inserted bar, the post-inserted bar is bound with a full-length steel bar, and the reinforcing bar configuration structure is relatively weak. In order to ensure that the construction column has good integrity and large bearing capacity within the overall length range, usually, the interval length of the stirrups is reduced within the length range of the post-inserted bar to increase the binding density of the stirrups. However, this method not only consumes more steel bars, but also is inconvenient for operation in the construction column structures of large buildings and high-rise buildings. At the same time, due to the large density of the stirrups, the operation space is limited, and multiple reasons lead to low construction efficiency;

[0006] Secondly, at the connection parts between the upper and lower ends of the reinforced concrete construction column and the ring beam or the beam and slab, there are problems of weak connection and insufficient strength, resulting in affecting the integrity and bending and shear resistance of the building structure.

[0007] In addition, the higher the number of storeys of the building and the greater the seismic intensity, the higher the requirements for the setting method of construction columns. Therefore, how to set the reinforcement structure form of construction columns and what kind of structural form of construction columns to adopt are major technical problems faced in the construction technology process of wall structures. Utility Model Content

[0008] One of the invention purposes of the present utility model is at least to provide a construction column reinforcement structure and a construction column. For the existing construction column reinforcement structure that uses post-inserted bars at both the upper and lower ends and reserves lengths for binding, there are problems such as large consumption of steel bars, low construction efficiency, and weak structural strength at the ends of construction columns affecting bending and shear resistance. By changing the post-inserted bar structure form of the construction column, the present utility model can effectively solve the problem of weak structure at both ends of the construction column, not only improving the integrity and stability of the construction column, but also reducing steel bar consumption and enhancing construction efficiency.

[0009] In order to achieve the above purpose, the technical solutions adopted by the present utility model include the following aspects.

[0010] A construction column reinforcement structure includes a first-end post-inserted bar and a second-end post-inserted bar. The first-end post-inserted bar or the second-end post-inserted bar is a full-length steel bar. The first-end post-inserted bar and the second-end post-inserted bar are connected, and stirrups are bound along the length directions of the first-end post-inserted bar and the second-end post-inserted bar.

[0011] Preferably, the construction column reinforcement structure further includes longitudinal bars. The first-end post-inserted bar and the second-end post-inserted bar are connected by longitudinal bars. The longitudinal bars include an intermediate section, a first end section bound to the first-end post-inserted bar, and a second end section bound to the second-end post-inserted bar. The stirrup binding spacing of the first end section and the second end section is smaller than that of the intermediate section.

[0012] Furthermore, the stirrup binding spacing of the first end section and the second end section is set to be between 120 - 180 mm, and the stirrup binding spacing of the intermediate section is set to be between 220 - 250 mm.

[0013] Preferably, both the first-end post-inserted bar and the second-end post-inserted bar adopt full-length steel bars.

[0014] Correspondingly, the present application also provides a construction column. The construction column is made by pouring concrete on the above-mentioned construction column reinforcement structure. The cross-sectional shape of the construction column along the length direction is a rectangular shape, and the side length of the cross-section is at least 240 mm.

[0015] Preferably, the construction column is in a variable cross-section size structural form, including a top section and / or a bottom section with a larger cross-section, and an intermediate section connecting the top section and the bottom section.

[0016] Furthermore, the first-end rebar embedding of the top section includes a rebar embedding section, a bending section, and a connecting section. The rebar embedding section and the connecting section are parallel, and the bending section is obliquely arranged between the rebar embedding section and the connecting section, such that the connecting section is closer to the center of the structural column than the rebar embedding section. The bending section is within the length range of the top section, and the lengths of the top section and the bottom section are respectively between 800 - 1200 mm.

[0017] Preferably, when the height of the structural column is greater than 5 meters, the first-end rebar embedding and the second-end rebar embedding of the structural column are φ14mm steel bars, and the spacing between adjacent two first-end rebar embedding steel bars does not exceed 400 mm.

[0018] Preferably, when the height of the structural column exceeds 10 m, the cross-sectional length of the structural column in the length direction is at least 300 mm, the width is at least 240 mm, the diameters of the first-end rebar embedding, the second-end rebar embedding, and the longitudinal bars of the structural column are φ14mm steel bars, and the stirrup spacing is not greater than 200 mm.

[0019] In summary, due to the adoption of the above technical solutions, the present utility model has at least the following beneficial effects:

[0020] 1. The first-end rebar embedding or the second-end rebar embedding adopts full-length steel bars, reducing the number of stirrup bindings in the parts other than the first-end section or the second-end section, and reducing the construction difficulty of rebar binding. Since the rebar binding part of the structural column rebar configuration is relatively weak, after pouring concrete, the bearing capacity of the formed reinforced concrete structural column at the binding part is poor. Moreover, the first-end rebar embedding and the second-end rebar embedding are exactly at the connection parts with the ring beam or the beam and slab, and stronger bearing capacity is required to ensure the structural safety of the reinforced concrete structural column. The way of adopting full-length steel bars for the first-end rebar embedding or the second-end rebar embedding solves these two problems simultaneously, ensuring the structural strength of the connection part between the upper or lower end of the reinforced concrete structural column and the ring beam (or the beam and slab);

[0021] 2. By setting the structural column as a variable cross-section structural form, including a top section and a bottom section connected to the beam at both ends, and an intermediate section connected between the top section and the bottom section, the cross-sectional dimensions of the top section and the bottom section are larger, and the length is between 800 - 1200 mm, which can improve the strength of the connection parts at both ends of the structural column, and further ensure the overall structural integrity and the flexural and shear resistance of the building structure.

[0031] Figure 1The figure shows the reinforcement structure of a construction column in an exemplary embodiment of the present utility model. The reinforcement structure of the construction column in this embodiment includes a first-end implanted bar 1 implanted into the first end of a beam 5 and a second-end implanted bar 2 implanted into a foundation beam 6. The first-end implanted bar 1 is a full-length steel bar (the second-end implanted bar 2 can also be set as a full-length steel bar). The first-end implanted bar 1 and the second-end implanted bar 2 are directly or indirectly connected. When the height of the construction column is lower than a certain range, the first-end implanted bar 1 and the second-end implanted bar 2 are directly connected. When the height of the construction column is greater than a certain value, the first-end implanted bar 1 and the second-end implanted bar 2 are indirectly connected. At this time, the reinforcement structure of the construction column further includes a longitudinal bar 3 connected to the first-end implanted bar 1 and the second-end implanted bar 2. As Figure 2 shown, the first-end implanted bar 1 and the second-end implanted bar 2 are connected through the longitudinal bar 3. Stirrups 4 are tied to the first-end implanted bar 1, the second-end implanted bar 2, and the longitudinal bar 3, and the spacing of the stirrup arrangement is smaller at the overlapping part of the steel bars. As Figure 1 and Figure 2 shown, Figure 1 at the overlapping and tying part of the lower end of the first implanted bar 1 and the second implanted bar 2 in Figure 2At the positions where the middle longitudinal bars 3 overlap and are tied to the first post-inserted bar 1 and the second post-inserted bar 2 at the upper and lower ends respectively, the spacing of the stirrups 4 is smaller than that in other places; the longitudinal bars 3 include a middle section 3A, a first end section 3B tied to the first end post-inserted bar 1, and a second end section 3C tied to the second end post-inserted bar 2. The tying spacing of the stirrups 4 in the first end section 3B and the second end section 3C is smaller than that in the middle section 3A. The tying spacing of the stirrups 4 in the first end section 3B and the second end section 3C is set to be between 120 - 180 mm, and the tying spacing of the stirrups 4 in the middle section 3A is set to be between 220 - 250 mm; the spacing of the stirrups 4 at the tying positions of the first end post-inserted bar 1 and the second end post-inserted bar 2 with the longitudinal bars 3 is set to be between 120 - 180 mm, and the tying spacing of the stirrups 4 in the remaining parts of the first end post-inserted bar 1 and the second end post-inserted bar 2 is set to be between 220 - 250 mm. There is no longitudinal bar 2, and the first end post-inserted bar 1 and the second end post-inserted bar 2 are directly tied. The stirrups at the overlapping part are set to be between 120 - 180 mm, and the remaining parts are set to be between 220 - 250 mm. The first end post-inserted bar 1 or the second end post-inserted bar 2 uses a full-length reinforcement bar, so that there is no situation of tying with longitudinal bars at the connection part between the upper or lower end of the reinforced concrete structural column and the ring beam (or beam and slab). On the one hand, it avoids tying the steel bars at the connection part between the reinforced concrete structural column and the ring beam or beam and slab, improves the strength of the connection part, and further enhances the integrity and flexural and shear resistance of the building structure. On the other hand, since the connection part between the reinforced concrete structural column and the ring beam or beam and slab is usually at a more difficult construction part (for example, the post-inserted bar at the upper end of the structural column is usually an aerial operation), using a full-length reinforcement bar for the first end post-inserted bar or the second end post-inserted bar reduces the number of stirrup ties in the parts other than the first end section or the second end section, and reduces the construction difficulty of steel bar tying. Due to the relatively weak tying part of the structural column reinforcement structure, after pouring the concrete, the bearing capacity of the formed reinforced concrete structural column at the tying part is poor, and the first end post-inserted bar and the second end post-inserted bar are exactly at the connection part with the ring beam or beam and slab, and stronger bearing capacity is required to ensure the structural safety of the reinforced concrete structural column. The method of using a full-length reinforcement bar for the first end post-inserted bar or the second end post-inserted bar solves these two problems at the same time and ensures the structural strength of the connection part between the upper or lower end of the reinforced concrete structural column and the ring beam (or beam and slab).

[0032] As one of the preferred embodiments, such as Figure 2As shown, both the first-end post-embedded bars 1 and the second-end post-embedded bars 2 adopt the way of full-length steel bars, so that the structural strength of the connection part between the upper end of the reinforced concrete structural column and the beam 5 is enhanced. At the same time, the structural strength of the connection part between the lower end of the reinforced concrete structural column and the foundation beam 6 is also enhanced, and the number of stirrups 4 at the upper and lower ends of the reinforced concrete structural column is reduced. The structural form of the first-end post-embedded bars 1 and / or the second-end post-embedded bars 2 adopting full-length steel bars can reduce the amount of steel bar binding materials. For example, if the structural column is 6 meters long, if the traditional method is adopted, the post-embedded bars at both the upper and lower ends of the structural column are 600 mm long, the embedding depth is 120 mm, and the longitudinal bars in the middle are 4.8 meters long. The binding number of the stirrups 4 is 26 to 30. By adopting the method of this embodiment, the number of stirrups 4 can be reduced by 2 - 4. For a large building group, a large amount of steel bar material cost can be saved, and the construction quality of the building is improved; the stirrup 4 includes a first stirrup 41 and a second stirrup 42. When the longitudinal bars 3 are arranged in two rows and three columns with six steel bars, the second stirrup 42 is connected to all six longitudinal bars (or the first-end post-embedded bars or the second-end post-embedded bars) along the perimeter direction of the cross-section of the structural column, and the first stirrup 41 is connected to some longitudinal bars (or the first-end post-embedded bars or the second-end post-embedded bars) of the cross-section of the structural column, as Figure 3 shown, which will be described in detail later.

[0033] When the height of the structural column is greater than 4 meters and does not exceed 5 meters, the reinforced concrete structural column is adopted. The first-end post-embedded bars 1, the second-end post-embedded bars 2 and the longitudinal bars 3 of the reinforced concrete structural column adopt φ12mm steel bars, and the stirrup 4 adopts φ6mm steel bars. When the height of the structural column exceeds 5 meters, the first-end post-embedded bars 1, the second-end post-embedded bars 2 and the longitudinal bars 3 of the reinforced concrete structural column preferably adopt φ14mm steel bars, and the stirrup 4 preferably adopts φ6mm steel bars. The number of the first-end post-embedded bars 1, the second-end post-embedded bars 2 and the longitudinal bars 3 is the same, that is, the number of the first-end post-embedded bars 1 at the upper end of the stirrup reinforced concrete structural column is the same as the number of the second post-embedded bars 2 at the lower end, and each post-embedded bar of the second-end post-embedded bars 2 is at the vertical projection position of each post-embedded bar of the first-end post-embedded bars 1, and the same number of longitudinal bars 3 are used for connection; the number and length of the longitudinal bars 3 are determined according to the height of the structural column and the full-length of the steel bars, and can be integers such as 0, 1, 2, 3, etc. For example, if the full-length of the first-end post-embedded bars 1, the second-end post-embedded bars 2 and the longitudinal bars 3 is set to 6 meters and the height of the structural column is H, when 5.88m ≤ H ≤ 11.16m for the height of the structural column, the number of longitudinal bars is 0, the length H1 of the first-end post-embedded bars is 6m, the embedding depth is 120mm, and the length H2 of the second-end post-embedded bars, H2 = (H - 5.88 + 0.12 + 0.6)m, and the embedding depth is 120mm, as Figure 1As shown in [figure]; when the height H of the structural column ≤ 5.88m, the number of longitudinal bars is 0, the length H1 of the first end embedded bar 1 is (H + 0.12)m, the embedded depth is 120mm, the length H2 of the second end embedded bar 2, H2 = 0.72m, the depth of the second end embedded bar 2 is 120mm, and the reserved length is 0.6m. At this time, H is at least 4m (when H is less than 4m, a reinforced concrete structural column is not required, and a concrete structural column can be used instead); when the height H of the structural column > 11.16m, the number of longitudinal bars 3 is 1, the length H1 of the first end embedded bar 1 is 6m, the embedded depth is 120mm, the length H2 of the second end embedded bar 2, H2 = 6m, the embedded depth is 120mm, the length H3 of the longitudinal bar 3, H3 = (H - 11.16)m, but the length of H3 should be kept at least 0.6m. At this time, reduce the length H2 of the second end embedded bar so that the lap joint of the first end embedded bar, the second end embedded bar and the longitudinal bar is about 0.6m; when the height H of the structural column > 17.16m, the number of longitudinal bars 3 is 2 or a larger integer, the length H1 of the first end embedded bar 1 is 6m, the embedded depth is 120mm, the length H2 of the second end embedded bar 2, H2 = 6m, the embedded depth is 120mm, and the longitudinal bars are spliced by 2 or more. However, the length of each longitudinal bar 3 should be kept at least 1.2m so that the lap joint length of the adjacent parts of the first end embedded bar 1, the second end embedded bar 2 and the multiple longitudinal bars 3 is about 0.6m. When the height of the structural column and the full-length length of the steel bar change, the number and length of the longitudinal bars 3 will also change. And when the embedded bar used is φ14mm, appropriately increase the embedded depth of the first end embedded bar 1 and the second end embedded bar 2.

[0034] As one of the preferred embodiments, the first end embedded bar 1, the second end embedded bar 2 and the longitudinal bar 3 are arranged in a multi-row and multi-column form according to the cross-sectional size of the structural column, and the layout spacing between two adjacent steel bars in each row or each column does not exceed 400mm. For the structural column at the corner of the house, increase the cross-sectional area of the structural column and at the same time increase the reinforcement density of the structural column, including reducing the layout spacing of the first end embedded bar, the second end embedded bar and the longitudinal bar, and reducing the layout spacing of the stirrups. Example 2

[0035] Figure 1 and Figure 2 , Figure 5 and Figure 6, respectively showing the structural columns of exemplary embodiments of the present utility model. The structural column is a reinforced concrete structural column, including the structural column reinforcement structure of Embodiment 1. The structural column 7 is formed by pouring concrete 8 on the structural column reinforcement structure. The structural column 7 of this embodiment includes one or both of the top section 71 and the bottom section 72, and the middle section 73 connected to the top section 71 and the bottom section 72 separately or simultaneously. Specifically, there are three structures: ① The bottom section and the middle section, one end of the middle section is connected to the bottom section, and the other end is connected to the beam on the top of the structural column; ② The top section and the middle section, one upper end of the middle section is connected to the top section, and one lower end is connected to the foundation beam; ③ The upper end of the structural column is the top section, the lower end is the bottom section, and the middle is the middle section. The middle section is connected between the bottom section and the top section. The cross-sectional shape of the structural column 7 along the length direction is a rectangular shape, the cross-sectional length is at least 240 mm, the cross-sectional width is at least 180 mm, and the aspect ratio of length to width is not greater than 2:1.

[0036] When the length of the structural column 7 is greater than 10 meters, the cross-sectional length of the structural column in the length direction is at least 300 mm, the width is at least 240 mm. The diameters of the first end rebar planting 1, the second end rebar planting 2 and the longitudinal bars 3 of the structural column 7 are preferably steel bars with a diameter of φ14 mm, and the spacing of the stirrups 4 should not be greater than 200 mm.

[0037] The cross-sectional dimensions of the three parts of the top section 71, the bottom section 72 and the middle section 73 of the structural column 7 along the length direction are the same. The structural column has a structural form with a constant cross-sectional size within the length range; another implementation manner is that the structural column has a structural form with a variable cross-sectional size. The cross-sectional dimensions of the top section 71 and the bottom section 72 of the structural column 7 along the length direction are larger than the cross-sectional dimensions of the middle section 73 along the length direction, and the axes of the top section 71, the bottom section 72 and the middle section 73 of the structural column are on the same straight line. The lengths of the top section 71 and the bottom section 72 are between 800 - 1200 mm. Since the top section 71 and the bottom section 72 of the structural column 7 are respectively connected to the ring beam or the beam and slab, setting the top section and the bottom section to a structural form with a larger cross-sectional area than the middle section can improve the strength of the connection part, and thus ensure the overall building structure and the bending and shear resistance capabilities. As Figure 5 shown, the top section 71 of the structural column 7 is connected to the beam 5, and the bottom section 72 is connected to the foundation beam 6.

[0038] When the structural column 7 has a structural form with a constant cross-sectional size, taking the longitudinal bars 3 of the structural column 7 as an example, the type of the stirrups 4 and the connection relationship with the longitudinal bars 3 are described (the connection relationship between the stirrups 4 and the first end rebar planting 1, and the connection relationship between the stirrups 4 and the second end rebar planting 2 are the same as the connection relationship with the longitudinal bars 3, and the type of the stirrups 4 is also corresponding in different parts). As Figure 3As shown, the number of longitudinal bars 3 is 6, arranged in two rows and three columns, namely the first longitudinal bar 31, the second longitudinal bar 32, and the third longitudinal bar 33 in the first row, and the fourth longitudinal bar 34, the fifth longitudinal bar 35, and the sixth longitudinal bar 36 in the second row. The stirrup 4 also includes a first stirrup 41 and a second stirrup 42. The first stirrup 41 is connected to 4 adjacent longitudinal bars among the 6 longitudinal bars. For example, it is hoop-bonded on the first longitudinal bar 31, the second longitudinal bar 32, the fourth longitudinal bar 34, and the fifth longitudinal bar 35, or hoop-bonded on the second longitudinal bar 32, the third longitudinal bar 33, the fifth longitudinal bar 35, and the sixth longitudinal bar 36. The second stirrup 42 is hoop-bonded outside all 6 longitudinal bars 3. Figure 4 Figure 4 shows the case where the number of longitudinal bars 3 is 9. The number of longitudinal bars is 9, arranged in three rows and three columns, namely the first longitudinal bar 31, the second longitudinal bar 32, and the third longitudinal bar 33 in the first row, the fourth longitudinal bar 34, the fifth longitudinal bar 35, and the sixth longitudinal bar 36 in the second row, and the seventh longitudinal bar 37, the eighth longitudinal bar 38, and the ninth longitudinal bar 39 in the third row. At this time, it is the reinforcement structure for the case of a relatively large cross-section of the structural column, applicable to occasions with higher requirements for the height of the structural column and the load-bearing capacity. The stirrup 4 includes, in addition to the first stirrup 41 and the second stirrup 42, a third stirrup 43. The first stirrup 41 can be hoop-bonded on the first longitudinal bar 31, the second longitudinal bar 32, the fourth longitudinal bar 34, and the fifth longitudinal bar 35, or hoop-bonded on the second longitudinal bar 32, the third longitudinal bar 33, the fifth longitudinal bar 35, and the sixth longitudinal bar 36, or hoop-bonded on the fourth longitudinal bar 34, the fifth longitudinal bar 35, the seventh longitudinal bar 37, and the eighth longitudinal bar 38, or also hoop-bonded on the fifth longitudinal bar 35, the sixth longitudinal bar 36, the eighth longitudinal bar 38, and the ninth longitudinal bar 39. The second stirrup 32 can be hoop-bonded on the longitudinal bars in the first two rows (that is, the first longitudinal bar 31, the second longitudinal bar 32, the third longitudinal bar 33, the fourth longitudinal bar 34, the fifth longitudinal bar 35, and the sixth longitudinal bar 36), or hoop-bonded on the longitudinal bars in the last two rows (that is, the fourth longitudinal bar 34, the fifth longitudinal bar 35, the sixth longitudinal bar 36, the seventh longitudinal bar 37, the eighth longitudinal bar 38, and the ninth longitudinal bar 39), or hoop-bonded on the longitudinal bars 3 in the first two columns (that is, the first longitudinal bar 31, the second longitudinal bar 32, the fourth longitudinal bar 34, the fifth longitudinal bar 35, the seventh longitudinal bar 37, and the eighth longitudinal bar 38), or also hoop-bonded on the longitudinal bars 3 in the last two columns (that is, the second longitudinal bar 32, the third longitudinal bar 33, the fifth longitudinal bar 25, the sixth longitudinal bar 36, the eighth longitudinal bar 38, and the ninth longitudinal bar 39). The third stirrup 43 is hoop-bonded outside all 9 longitudinal bars. Since the number of the first-end implanted bars 1, the second-end implanted bars 2, and the longitudinal bars 3 is the same within the overall length range of the structural column, the stirrups 4 tied to the first implanted bar 1 and the second implanted bar 2 have the same connection method as described above, which will not be elaborated here. Moreover, when the number of longitudinal bars 3 is less than 6 (such as 4) or greater than 9 (such as 12), the type of stirrup 4 and the connection method with the longitudinal bars 3 are correspondingly changed.

[0039] When the structural column 7 adopts a variable cross-section size structure form, the reinforcement structure mode of the structural column 7 can be the same as the stirrup arrangement mode of the equal cross-section structural column, only increasing the concrete pouring cross-section size of the top section and the bottom section of the structural column, without changing the reinforcement structure form. For example Figure 5 as shown; the reinforcement structure form of the structural column with variable cross-section size can also adopt the method as shown in Figure 6 . A bent section 102 is provided on part of the first-end implanted bars 1, including an implanted bar section 101, a bent section 102 and a connecting section 103. The implanted bar section 101 and the connecting section 103 are parallel. The bent section 102 is obliquely arranged between the implanted bar section 101 and the connecting section 103, so that the connecting section 103 is closer to the center of the structural column 7 than the implanted bar section. The bent section 102 is arranged within the length ranges of the top section 71 and the bottom section 72. When the number of the first-end implanted bars 1 of the structural column 7 is 6, that is, arranged in two rows and three columns, it is illustrated by Figure 3 . The preferred implementation mode is that 4 first-end implanted bars 1 connected to the first longitudinal bar 31, the third longitudinal bar 33, the fourth longitudinal bar 34 and the sixth longitudinal bar 36 have bent sections 102, and the first-end implanted bars 1 connected to the second longitudinal bar 32 and the fifth longitudinal bar 35 do not have bent sections 102. It can also adopt the way that the first-end implanted bars 1 in the first row are bent towards the first-end implanted bars 1 in the second row, and at the same time, the first-end implanted bars 1 in the second row are bent towards the first-end implanted bars 1 in the first row; when the number of the first-end implanted bars 1 of the structural column 7 is 9, that is, arranged in three rows and three columns, it is illustrated by Figure 4 . The preferred implementation mode is that two rows of first-end implanted bars 1 connected to the longitudinal bars 3 in the first row and the longitudinal bars 3 in the third row have bent sections 102, and the first-end implanted bars 1 in the second row connected to the longitudinal bars 3 do not have bent sections 102. It can also adopt the way that two columns of first-end implanted bars 1 connected to the longitudinal bars 3 in the first column and the longitudinal bars 3 in the third column have bent sections 102, and the first-end implanted bars 1 in the second column do not have bent sections 102; when the number of the first-end implanted bars 1 of the structural column 7 is other, adopt the same way to make the first-end implanted bars 1 close to the surface of the structural column bend towards the center of the structural column to form bent sections 102.

[0040] A further preferred implementation mode is that corresponding to the structural form of the variable cross-section structural column, the first-end implanted bars 1 and the second-end implanted bars 2 are respectively bent alone or at both ends simultaneously, and then through concrete pouring, a structural column 7 with a separately larger cross-section first end section 71 or second end section 72, or a structural form with both a first end section 71 and a second end section 72 is formed.

[0041] The above is only a detailed description of the specific implementation mode of the present invention, rather than a limitation to the present invention. Various substitutions, variations and improvements made by those skilled in the relevant technical fields without departing from the principle and scope of the present invention should be included within the protection scope of the present invention.
