Detailed Description

These and other aspects, features and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment, which is to be read in connection with the accompanying drawings.

Please refer to fig. 17, 18, 19 and 20, which illustrate an embodiment of a three-dimensional structure of a reinforcing bar of a building according to the present invention, which is a column structure in a building. As shown in fig. 17, the three-dimensional structure of reinforcing bars 100 of the present invention includes a plurality of main bars 10 and a plurality of stirrups (first stirrups) 20. The main ribs 10 are upright and can be inserted into a base material, such as a ground or a foundation, the main ribs 10 are arranged in parallel, and the main ribs 10 can be arranged around a polygon as required. In the present embodiment, a square column is taken as an example, so that the main bars 10 are arranged around a quadrangle.

A plurality of stirrups 20 are sleeved on the main reinforcement 10, and each stirrup 20 is tied on the main reinforcement 10 at a proper position. Each stirrup 20 is formed by continuously bending a steel bar to form a closed geometric shape, in this embodiment, each stirrup 20 is bent to form a quadrangle, in order to match the structure of a four-corner column, the first polygon is a quadrangle, the stirrups 20 are respectively arranged around the main reinforcements 10 and are sequentially arranged along the extending direction of the main reinforcements 10, that is, the stirrups 20 are sequentially sleeved and positioned on the main reinforcements 10 from bottom to top.

In the present embodiment, in order to reinforce the strength of the corners of the pillar structure, each hoop 20 includes a body 20a and a pair of anchoring hooks 20b, the body 20a includes a plurality of sides 21 and at least one connecting portion 22, and the anchoring hooks 20b are connected to the body 20a and located at the beginning and the ending ends of the hoop 20. In the present embodiment, each stirrup 20 includes four sides 21, a connecting portion 22 is disposed between two adjacent sides 21, and at the corner of the pillar structure, the two adjacent sides 21 and the connecting portion 22 surround to form a triangle. For example, the side edges 21 include a first side edge 21a and a second side edge 21b, the first side edge 21a includes a first overlapping portion 21a-1, the second side edge 21b includes a second overlapping portion 21b-1, the first overlapping portion 21a-1 and the second overlapping portion 21b-1 overlap each other in a direction along the extending direction of the main ribs 10, and the first overlapping portion 21a-1 is connected to the second overlapping portion 21b-1 through the connecting portion 22, and in the embodiment, the first overlapping portion 21a-1 and the second overlapping portion 21b-1 are located at the end of the first side edge 21a and the end of the second side edge 21b, so that the connecting portion 22 connects the end of the first side edge 21a and the end of the second side edge 21 b.

As shown in fig. 19 and 20, the first overlapping portion 21a-1 and the second overlapping portion 21b-1 form a vertical distance D along the extending direction of the main reinforcement 10, so that when the stirrups 20 are bound and positioned on the main reinforcement 10, the first overlapping portion 21a-1 and the second overlapping portion 21b-1 of each stirrup 20 are separated from each other by the vertical distance D in the extending direction of the main reinforcement 10 and are staggered with respect to each other to form a structure similar to a three-dimensional spiral stirrup with respect to the main reinforcement 10.

Referring to fig. 1, 2, 3 and 4, which illustrate a two-dimensional stirrup structure of the prior art, corresponding to the embodiment of fig. 17 to 20, like elements are given like reference numerals and description thereof is omitted, except that the first and second overlapping portions 21a-1 and 21b-1 of each stirrup 20 do not generate the vertical distance D, because the two-dimensional stirrup structure shown in fig. 1 to 4 can be produced only by existing equipment, so that the stirrup 20 of the present invention can be formed by the existing two-dimensional stirrup structure by pulling the first and second overlapping portions 21a-1 and 21b-1 of the first and second sides 21 a-21 b and 21a-1 of the first and second sides 21 a-21 b by opposite forces, and then binding or welding the first and second overlapping portions 21a-1 and 21b-1 pulled by the vertical distance D to the main bar 10, thereby the first overlap portion 21a-1 and the second overlap portion 21b-1 are positioned on the main bar 10 in a structure spaced apart by a vertical distance D.

In addition, referring to fig. 19 and 20 and fig. 3 and 4, since the first overlapping portion 21a-1 and the second overlapping portion 21b-1 are connected by the connecting portion 22, and further, the distance between the first overlapping portion 21a-1 and the second overlapping portion 21b-1 is limited by the connecting portion 22, the maximum value of the vertical distance D generated after the first overlapping portion 21a-1 and the second overlapping portion 21b-1 are separated is the length of the connecting portion 22, but because of the high rigidity of the steel bar material, the maximum value of the vertical distance D generated after the first overlapping portion 21a-1 and the second overlapping portion 21b-1 are separated is 3/4 of the length of the connecting portion 22 in the actual operation.

In addition, the distance between the stirrups 20 can be adjusted according to the vertical distance D, for example, as shown in fig. 1 and 2, the distance between the second overlapped portion 21b-1 of one stirrup 20 and the first overlapped portion 21a-1 of the adjacent stirrup 20 can be greater than the vertical distance D between the first overlapped portion 21a-1 and the second overlapped portion 21b-1 of the stirrup 20 itself, or in another embodiment, the distance between the second overlapped portion 21b-1 of one stirrup 20 and the first overlapped portion 21a-1 of the adjacent stirrup 20 can be equal to the vertical distance D between the first overlapped portion 21a-1 and the second overlapped portion 21b-1 of the stirrup 20 itself. Thus, the distance between the stirrups 20 can be adjusted in accordance with the vertical distance D, so that a design more flexible than a three-dimensional stirrup can be obtained in terms of structural design.

In terms of the hoop strength, the conventional hoop structure shown in fig. 1 and 2 has a structure in which the first overlapping portion 21a-1 of the first side 21a and the second overlapping portion 21b-1 of the second side 21b are adjacently disposed, so that the hoop strength of the main bar 10 generated by the hoop 20 is concentrated at the adjacent first overlapping portion 21a-1 and second overlapping portion 21b-1, and the hoop strength between the two hoop 20 is greatly reduced, which causes an uneven hoop strength along the extending direction of the main bar 10, and the first overlapping portion 21a-1 and the second overlapping portion 21b-1 of the hoop 20 shown in fig. 14 and 15 are disposed in a staggered manner with respect to the main bar 10, this results in a more even hooping force in the direction along which the main bead 10 extends.

Although the present embodiment is described by taking the RC structure as an example, the present invention is not limited thereto, and the building reinforcing steel bar three-dimensional structure 100 of the present invention can also be applied to the SRC structure.

Although fig. 17 to 20 illustrate the structure of the stirrup for the column, which forms a triangle at four corners, the present invention is not limited thereto, and the three-dimensional structure of the reinforcing bar for the building can be applied to other structures for the column as long as the overlapping portions are formed at both sides of the stirrup.

Please refer to fig. 21, 22 and 23, which illustrate another embodiment of the present invention for a three-dimensional structure of a building rebar. The three-dimensional structure of the reinforcing bars of the building of the present embodiment is applied to a structure of a beam. The three-dimensional structure of reinforcing bars 100 'of the building of this embodiment includes a plurality of main bars 10 and a plurality of stirrups (first stirrups) 20'. The main bars 10 are arranged in parallel transversely, in the embodiment, a square beam is taken as an example for illustration, so the main bars 10 are arranged in a quadrilateral shape, the stirrups 20 'are sequentially sleeved around the main bars 10 along the extending direction of the main bars 10, and the stirrups 20' are positioned on the main bars 10 in a binding or welding manner.

Each stirrup 20 ' is formed by continuously bending a steel bar into a closed geometric shape, and includes a body 20a ' and a pair of anchoring hooks 20b ', the anchoring hooks 20b ' being connected to the body 20a and located at the beginning and the end of the stirrup 20 '. The body 20a 'includes a plurality of sides 21', in this embodiment, the closed geometrical shape is a quadrilateral in order to fit the structure of the quadrangular beam, and in this embodiment, the first polygon is formed by the first loop L1 and the second loop L2 in a partially overlapping manner. The stirrups 20 'are respectively disposed around the main reinforcements 10 and sequentially arranged along the extending direction of the main reinforcements 10, that is, the stirrups 20' are sequentially sleeved and positioned on the main reinforcements 10 from left to right or from right to left.

As shown in fig. 22, the first loop L1 includes a first side 21a ', the second loop L2 includes a second side 21b', wherein the first loop L1 and the second loop L2 are connected by the connection portion 22a ', the first side 21 a' of the first loop L1 includes a first overlapping portion 21a-1 ', the second side 21b' of the second loop L2 includes a second overlapping portion 21b-1 ', the first overlapping portion 21 a-1' and the second overlapping portion 21b-1 'overlap in a direction extending along the main rib 10, and the first overlapping portion 21 a-1' is connected to the second overlapping portion 21b-1 'through the connection portions 22 a', 22b ', and 22 c', wherein the connection portion 22a 'and the connection portion 22 b' belong to the first loop L1.

As shown in fig. 21 and 23, in the present embodiment, the first loop L1 and the second loop L2 are caused by two forces in opposite directions, so that the first overlapping portion 21a-1 ' of the first side 21a ' and the second overlapping portion 21b-1 ' of the second side 21b ' are separated by a vertical distance D '.

Referring to the aforementioned three-dimensional structure of the building reinforcing bar for a beam shown in fig. 5, 6 and 7, which corresponds to the embodiment of fig. 21, 22 and 23 of the present invention, like elements are given like reference numerals and description thereof is omitted, and the structure of the first overlapping portion 21a-1 ' and the second overlapping portion 21b-1 ' separated by a vertical distance D ' may be formed by the two-dimensional stirrup structure shown in fig. 6 and 7, in which the first loop L1 and the second loop L2 are moved in opposite directions by two opposite forces. In practice, the first and second overlapping portions 21a-1 'and 21 b-1' separated by the vertical distance D 'may be simultaneously bound to the main bar 10 such that the first and second overlapping portions 21 a-1' and 21b-1 'are positioned on the main bar 10 while maintaining the vertical distance D' between the first and second overlapping portions 21a-1 'and 21 b-1'.

Similarly, referring to fig. 21 and 23 and fig. 5 and 7, since the first loop L1 and the second loop L2 are connected by the connection portion 22a ', and further, the first loop L1 and the second loop L2 are limited by the connection portion 22 a', the maximum vertical distance D 'between the first overlapping portion 21 a-1' of the first loop L1 and the second overlapping portion 21b-1 'of the second loop L2 is the total length of the connection portion 22 a', but because of the high rigidity of the steel bar, the vertical distance D 'is less than 3/4 of the total length of the connection portion 22 a' in the actual operation.

Similarly, as shown in fig. 21, the distance between the stirrups 20 'can be adjusted corresponding to the vertical distance D', and the distance between the second overlap 21b-1 'of the stirrup 20' and the first overlap 21a-1 'of the adjacent stirrup 20' is greater than the vertical distance D 'between the first overlap 21 a-1' and the second overlap 21b-1 'of the stirrup 20' itself. However, in another embodiment, the distance between the second overlapping portion 21b-1 'of the stirrup 20' and the first overlapping portion 21a-1 'of the adjacent stirrup 20' may be equal to the vertical distance D 'between the first overlapping portion 21 a-1' and the second overlapping portion 21b-1 'of the stirrup 20' itself. This provides structural design flexibility that is not available with the helical three-dimensional stirrup structure.

In addition, since the vertical distance D 'between the first overlapped portion 21 a-1' and the second overlapped portion 21b-1 'of each stirrup 20' can be matched with the distance between the two stirrups 20 ', the first overlapped portion 21 a-1' and the second overlapped portion 21b-1 'of each stirrup 20' can be arranged in a staggered manner along the extending direction of the main reinforcement 10, thereby obtaining a more even hooping force.

Although fig. 21 to 23 illustrate the structure of the stirrup for the beam in which the first loop L1 and the second loop L2 are partially overlapped, the present invention is not limited thereto, and other structures for the beam may be applied to the three-dimensional structure of the reinforcing bar of the building as long as the overlapping portions are formed at both sides of the stirrup.

Please refer to fig. 24, 25 and 26, which illustrate another embodiment of the present invention for a three-dimensional structure of a reinforcing bar of a building. The three-dimensional structure of the reinforcing bars of the building of this embodiment is applied to a wall structure, which is an L-shaped wall plate in this embodiment. The three-dimensional structure of reinforcing bars 100 "of the building of the present embodiment includes a plurality of main bars 10 and a plurality of stirrups 20". The main bars 10 are inserted into the ground, and because the present embodiment is an L-shaped wall plate, the main bars 10 are arranged in parallel to each other to form an L-shaped polygon. The stirrups 20 "are sequentially sleeved on the main bars 10 along the extending direction of the main bars 10, and the stirrups 20" are positioned on the main bars 10 in a binding or welding manner.

The stirrup 20 "is formed by continuously bending a steel bar into a closed geometric shape, and in this embodiment, the stirrup 20" includes a body 20a "and a pair of anchoring hooks 20 b", the anchoring hooks 20b "are connected to the body 20 a", and the pair of anchoring hooks 20b "are respectively located at the beginning and the end of the stirrup 20". The main body 20a "is a polygon including a plurality of sides 21", which includes a third loop L3 and a fourth loop L4, wherein the third loop L3 is a quadrilateral structure, the fourth loop L4 is an L-shaped structure, the third loop L3 is integrally overlapped with the fourth loop L4, and the third loop L3 is connected to the fourth loop L4 by a connecting portion 22a ".

The third loop L3 includes a first side 21a ", the fourth loop L4 includes a second side 21 b", the first side 21a "and the second side 21 b" overlap in the direction along the main rib 10, and the first side 21a "is connected to the second side 21 b" through the connecting portion 22a ", the connecting portion 22 b", and the connecting portion 22c ", the first side 21 a" includes a first overlapping portion 21a-1 ", and the second side 21 b" includes a second overlapping portion 21b-1 ". In the present embodiment, the first overlapping portion 21a-1 "is the whole of the first side 21 a", and the second overlapping portion 21b-1 "is a partial length of the second side 21 b". The third loop L3 and the fourth loop L4 are separated by a vertical distance D' by two oppositely directed forces.

Referring to fig. 8, 9 and 10, the conventional three-dimensional structure of building reinforcing bars for walls corresponds to the embodiment of fig. 24, 25 and 26, like elements are given like reference numerals and description thereof is omitted, and the first overlapping part 21a-1 ″ and the second overlapping part 21b-1 ″ are spaced apart by the vertical distance D by applying force to the third loop L3 and the fourth loop L4 in opposite directions by the conventional two-dimensional stirrup structure shown in fig. 9 and 10. In practice, the first and second overlapping portions 21a-1 and 21b-1 "separated by the vertical distance D" may be simultaneously bound or welded to the main bar 10 such that the first and second overlapping portions 21a-1 and 21b-1 "are positioned on the main bar 10 while maintaining the vertical distance D between the first and second overlapping portions 21a-1 and 21 b-1".

In addition, the third circuit L3 and the fourth circuit L4 are connected by the connection portion 22a ", and further, the connection portion 22 a" limits the space between the third circuit L3 and the fourth circuit L4, so that when the third circuit L3 and the fourth circuit L4 are pulled apart by the force in the opposite directions, the maximum value of the vertical distance D "between the first overlapping portion 21 a-1" and the second overlapping portion 21b-1 "is the total length of the connection portion 22 a", but because the rigidity of the steel bar material is high, the vertical distance D "is smaller than 3/4 of the total length of the connection portion 22 a" in the actual operation.

In addition, the distance between two adjacent stirrups 20 "can be adjusted according to the design requirement by matching the vertical distance D" between the first overlapped part 21a-1 "and the second overlapped part 21 b-1". In one embodiment, as shown in FIG. 8, the distance between the second overlapping portion 21b-1 "of one stirrup 20" and the first overlapping portion 21a-1 "of another adjacent stirrup 20" is greater than the vertical distance D between the first overlapping portion 21a-1 "and the second overlapping portion 21 b-1" of the stirrup 20 "itself. In another embodiment, however, the distance between the second overlapping portion 21b-1 "of one stirrup 20" and the first overlapping portion 21a-1 "of another adjacent stirrup 20" may be equal to the vertical distance D between the first overlapping portion 21a-1 "and the second overlapping portion 21 b-1" of the stirrup 20 "itself. This provides structural design flexibility that is not available with the helical three-dimensional stirrup structure.

In addition, since the vertical distance D "between the first overlapped portion 21 a-1" and the second overlapped portion 21b-1 "of each stirrup 20" can match the distance between the two stirrups 20 ", the first overlapped portion 21 a-1" and the second overlapped portion 21b-1 "of each stirrup 20" can be arranged in a staggered manner along the extending direction of the main reinforcement 10, thereby obtaining a more even hooping force.

Although the present embodiment describes the three-dimensional structure of building rebars for wall structure with L-shaped stirrups, the present invention is not limited thereto, and any wall structure with sides having overlapping portions is suitable for the three-dimensional structure of building rebars of the present invention.

Please refer to fig. 27, 28 and 29, which illustrate another embodiment of the present invention for a three-dimensional structure of a reinforcing bar of a building.

The three-dimensional structure of the building reinforcing steel bar 100 ' of the embodiment includes a plurality of main bars 10, a plurality of first stirrups 20 ' and a plurality of second stirrups 30 '. The main bars 10 are arranged parallel to each other and inserted into a substrate, such as a foundation, and the first stirrups 20 '"and the second stirrups 30'" are arranged along the direction in which the main bars 10 extend and are positioned at the main bars 10 in a staggered manner.

Each first stirrup 20 '"forms a square structure surrounding the groined type, each first stirrup 20'" comprises a plurality of sides 21 '"and a plurality of connecting parts 22'", the sides 21 '"and the connecting parts 22'" are connected with each other to form a fifth loop L5, a sixth loop L6 and a seventh loop L7, the fifth loop L5 is positioned above the sixth loop L6, and the sixth loop L6 is positioned above the seventh loop L7. The side edges 21 '"include a first side edge 21 a'" and a second side edge 21b '", the first side edge 21 a'" overlaps the second side edge 21b '"and the first side edge 21 a'" is connected to the second side edge 21b '"by the connecting portions 22 a'", 22b '"and 22 c'", the first side edge 21a '"includes a first overlapping portion 21 a-1'", the first overlapping portion 21a-1 '"overlaps the second side edge 21b'", the second side edge 21b '"includes a second overlapping portion 21b'", and the second overlapping portion 21b '"overlaps the first side edge 21 a'". In the present embodiment, the first side 21a '"entirely overlaps the second side 21b'", so the first overlapping portion 21a-1 '"corresponds to the entirety of the first side 21 a'". Although in the present embodiment, the first stirrup 20 '"forms a square-around- # -shaped structure, it is not limited thereto, and in another embodiment, the first stirrup 20'" may also be a structure that merely assumes a # -shape without a portion of the peripheral square.

Each second stirrup 30 "'is circular, and after the second stirrups 30"' are positioned on the main reinforcement 10, the second stirrups 30 "'correspond to the central part of the # -shaped structure of the first stirrup 20"', and the second stirrups 30 "'and the first stirrups 20"' are staggered along the extending direction of the main reinforcement 10, each first stirrup 20 "'has a first characteristic length in the direction perpendicular to the extending direction of the main reinforcement 10, each second stirrup 30"' has a second characteristic length in the direction perpendicular to the extending direction of the main reinforcement 10, the second characteristic length is smaller than the first characteristic length, in this embodiment, the first characteristic length is the length of the side or the diagonal of the first stirrup 20 "', and the second characteristic length is the diameter of the second stirrup 30"'.
