Description

Technical Field

[0001] This invention belongs to the field of steel structure installation technology, and in particular relates to a multi-legged box column reinforcement structure. Background Technology

[0002] A typical box column is a rectangular structure composed of four wall panels (i.e., two flanges and two webs). The outer side of the box column is usually equipped with multiple sets of I-beam brackets to connect with other steel structures. The I-beam brackets bear a large load. In order to improve the overall deformation resistance of the box column, several internal partitions with round holes are usually welded inside the box column, and cross-shaped steel plates are welded at the positions of the brackets inside the box column.

[0003] In the installation of box-type columns, a ground pump jacking method is generally used for filling the column with concrete. This method involves high jacking heights, a large weight of concrete, and numerous corbels and cross-shaped steel plates within the box-type column. The intersections of these plates obstruct the jacking path of the concrete and divide it into four jacking spaces, resulting in slow concrete flow and high jacking pressure, thus increasing the difficulty of the concrete jacking operation. Furthermore, the internal diaphragm support capacity is limited, especially when used in heavy steel structure box-type columns, where the support effect is unsatisfactory. To solve these construction problems, the internal reinforcement structure of the box-type column needs to be optimized. Summary of the Invention

[0004] The main objective of this invention is to propose a multi-legged box-type column reinforcement structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-legged box column reinforcement structure includes a box column, which is divided into a box column base, a lower box column, and an upper box column from bottom to top.

[0007] A column base plate is fixedly installed at the bottom of the box-shaped column base. A transition reinforcing plate is fixedly installed above the column base plate. The transition reinforcing plate has four openings. The column base plate and the transition reinforcing plate are fixedly connected by a cross-shaped steel plate. The four openings are respectively connected to the four spaces divided by the cross-shaped steel plate. A first inner partition plate is fixedly installed above the transition reinforcing plate. The first inner partition plate includes a first rectangular plate and a ring. The ring is fixedly installed at the center of the first rectangular plate, and its two ends extend out of the upper and lower surfaces of the first rectangular plate, respectively. The transition reinforcing plate and the first inner partition plate are fixedly connected by a T-shaped assembly. The T-shaped assembly includes four T-shaped steels spaced 90° apart.

[0008] The lower box column is fixedly installed with several I-shaped bracket assemblies. The upper and lower flanges of the I-shaped bracket assembly are respectively provided with first inner partitions. The two corresponding first inner partitions are fixedly connected by T-shaped assemblies.

[0009] The upper box-shaped column has several second inner partitions fixedly installed inside. Each second inner partition includes a second rectangular plate and a rectangular ring. The rectangular ring is fixedly installed at the center of the second rectangular plate, with its two ends extending out of the upper and lower surfaces of the second rectangular plate, respectively. The upper box-shaped column has several I-shaped bracket assemblies fixedly installed outside. The upper and lower flanges of each I-shaped bracket assembly are respectively provided with second inner partitions. The corresponding second inner partitions are fixedly connected by T-shaped assemblies.

[0010] Preferably, the T-shaped steel includes a horizontal plate and a vertical plate that are perpendicular to each other. The vertical plate is fixedly connected to the wall panel corresponding to the box-shaped column, and the horizontal plate is fixedly connected to the protruding part of the circular / rectangular ring.

[0011] Preferably, the upright plate is aligned with the web of the I-shaped corbel assembly.

[0012] Preferably, if all the I-shaped corbel groups are equal-height corbels, the web of the equal-height corbel is located at the center of the box column wall panel, and the four T-shaped steels are arranged in a circle at 90° intervals, with the corresponding vertical plates aligned with the web of the equal-height corbels respectively;

[0013] If the I-shaped bracket group has equal-height brackets and eccentric brackets, the web of the eccentric bracket is not in the center of the box column wall panel, the four T-shaped steels are arranged non-circularly at 90° intervals, and the vertical plate corresponding to the eccentric bracket is aligned with the web of the eccentric bracket.

[0014] If the I-shaped bracket assembly has equal-height brackets and variable-step brackets, the webs of the equal-height brackets and variable-step brackets are located at the center of the box-shaped column wall panel. The upper flanges of the equal-height brackets and variable-step brackets are respectively provided with a first inner partition / second inner partition. The lower flanges of the equal-height brackets are respectively provided with a first inner partition / second inner partition. The lower flanges of the variable-step brackets are respectively provided with a first inner partition / second inner partition. The three first inner partitions / second inner partitions are fixedly connected by two T-shaped assemblies. The four T-shaped steels are arranged in a circle at 90° intervals, and the corresponding uprights are aligned with the webs of the equal-height brackets and variable-step brackets.

[0015] Preferably, the lower box column is provided with a number of tie members inside, which tie and support the wall panels of the lower box column. The tie members include a number of sets of connecting beams arranged at equal intervals in height, and adjacent sets of connecting beams are perpendicular to each other.

[0016] Preferably, the intermediate connecting beams are fixedly connected to the wall panels of the lower box column via a rectangular frame, the rectangular frame having a rectangular hole in the middle, and the remaining connecting beams are fixedly connected to the wall panels of the lower box column via connecting plates.

[0017] Preferably, the connecting beam is an angle steel structure, and a set includes two connecting beams, and the connecting plate is a trapezoidal steel plate structure.

[0018] Preferably, the distances between the two ends of the ring extending out of the top and bottom surfaces of the first rectangular plate are equal, and the distances between the two ends of the rectangular ring extending out of the top and bottom surfaces of the second rectangular plate are equal.

[0019] Preferably, the column base plate has four vent holes, and the four vent holes are respectively connected to the four spaces divided by the cross-shaped steel plate.

[0020] Preferably, the four corners of the first rectangular plate and the second rectangular plate are chamfered.

[0021] This invention provides a multi-legged box-type column reinforcement structure, which has the following beneficial effects;

[0022] 1. In the lower box column, the first inner diaphragm and the T-shaped assembly support and reinforce the wall panel at the I-shaped bracket position. Since the four T-shaped steels of the T-shaped assembly have gaps and rings in the middle, they do not obstruct the jacking path of the concrete. While achieving the effect of support and reinforcement, they do not affect the flow of concrete, which greatly reduces the jacking pressure of the concrete and thus reduces the construction difficulty of the concrete jacking operation.

[0023] 2. Several second inner diaphragms are used to support and reinforce the wall panels in the upper box-shaped column. The center of the second rectangular plate is a rectangular ring, which has a larger channel than a circular ring, making it more conducive to concrete jacking. At the same time, in the upper box-shaped column, the wall panels at the I-shaped bracket positions are supported and reinforced by the second inner diaphragms and T-shaped assemblies, which will not obstruct the jacking path of the concrete. While achieving the effect of support and reinforcement, it will not affect the flow of concrete, greatly reducing the jacking pressure of the concrete and thus reducing the construction difficulty of the concrete jacking operation.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limiting this invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Examples, such as Figure 1 As shown, a multi-legged box column reinforcement structure includes a box column, which is divided into a box column base 1, a lower box column 2, and an upper box column 3 from bottom to top.

[0039] like Figure 2-4 As shown, a column base plate 4 is fixedly installed at the bottom of the box-shaped column base 1. A transition reinforcing plate 5 is fixedly installed above the column base plate 4. The transition reinforcing plate 5 has four openings 51. The column base plate 4 and the transition reinforcing plate 5 are fixedly connected by a cross-shaped steel plate 6. The four openings 51 are respectively connected to the four spaces divided by the cross-shaped steel plate 6. A first inner partition plate 7 is fixedly installed above the transition reinforcing plate 5. The first inner partition plate 7 includes a first rectangular plate 71 and a ring 72. The ring 72 is fixedly installed at the center of the first rectangular plate 71, and its two ends extend out of the upper and lower surfaces of the first rectangular plate 71 respectively. The transition reinforcing plate 5 and the first inner partition plate 7 are fixedly connected by a T-shaped assembly 8. The T-shaped assembly 8 includes four T-shaped steels 81 spaced 90° apart.

[0040] In the box column base 1, the cross-shaped steel plate 6, the transition reinforcement plate 5, and the first inner partition plate 7 support and reinforce the wall panel of the box column base 1. The T-shaped assembly 8 fixes the transition reinforcement plate 5 and the first inner partition plate 7. During the concrete jacking construction, holes are opened in the wall panel between the transition reinforcement plate 5 and the first inner partition plate 7 to insert concrete guide pipes. The concrete flows into the four spaces divided by the cross-shaped steel plate 6 through the four openings 51. After filling, the concrete is jacked up through the middle of the four T-shaped steel plates 81 and the ring 72 without obstructing the jacking path of the concrete.

[0041] like Figure 1 As shown, several I-shaped bracket assemblies 9 are fixedly installed on the outside of the lower box column 2. The upper and lower flanges of the I-shaped bracket assembly 9 are respectively provided with first inner partitions 7, and the two corresponding first inner partitions 7 are fixedly connected by T-shaped assemblies 8.

[0042] In the lower box column 2, the first inner partition 7 and the T-shaped assembly 8 support and reinforce the wall panel at the I-shaped bracket position. Since there is a gap between the four T-shaped steels 81 of the T-shaped assembly 8 and the presence of the ring 72, it will not obstruct the jacking path of the concrete. While achieving the effect of support and reinforcement, it will not affect the flow of concrete, greatly reducing the jacking pressure of the concrete and thus reducing the construction difficulty of the concrete jacking operation.

[0043] The upper box-shaped column 3 has several second inner partitions 10 fixedly installed inside. Each second inner partition 10 includes a second rectangular plate 101 and a rectangular ring 102. The rectangular ring 102 is fixedly installed at the center of the second rectangular plate 101, with its two ends extending out of the upper and lower surfaces of the second rectangular plate 101, respectively. The upper box-shaped column 3 has several I-shaped bracket assemblies 9 fixedly installed outside. The upper and lower flanges of each I-shaped bracket assembly 9 are respectively provided with second inner partitions 10. The corresponding second inner partitions 10 are fixedly connected by T-shaped assemblies 8.

[0044] In comparison, the strength requirements for the upper box column 3 are much lower than those for the box column base 1 and the lower box column 2. However, the concrete height is greater, resulting in higher concrete pressure and making it difficult to lift. Therefore, several second inner partitions 10 are used in the upper box column 3 to support and reinforce the wall panels. The center of the second rectangular plate 101 is a rectangular ring 102. The width of the rectangular ring 102 is larger than that of the circular ring 72, which is more conducive to the lifting of the concrete. At the same time, in the upper box column 3, the wall panels at the I-shaped bracket positions are supported and reinforced by the second inner partitions 10 and T-shaped assemblies 8, which do not obstruct the lifting path of the concrete. While achieving the effect of support and reinforcement, it does not affect the flow of concrete, greatly reducing the lifting pressure of the concrete and thus reducing the construction difficulty of the concrete lifting operation. The first rectangular plate 71 and the second rectangular plate 101 can also bear most of the weight generated by the concrete in the vertical direction, which helps to reduce the lifting pressure of the concrete.

[0045] like Figure 4 As shown, in a specific embodiment, the T-shaped steel 81 includes a horizontal plate 811 and a vertical plate 812 that are perpendicular to each other. The vertical plate 812 is vertically fixedly connected to the wall panel corresponding to the box column. The horizontal plate 811 is fixedly connected to the extended portion of the circular ring 72 / rectangular ring 102, supporting the wall panel while connecting two first inner partitions 7 / second inner partitions 10.

[0046] In one specific embodiment, the upright plate 812 is aligned with the web of the I-shaped bracket group 9, directly resisting the pressure of the I-shaped bracket group 9 on the wall panel.

[0047] In a specific embodiment, such as Figure 5 As shown, if the I-shaped bracket group 9 consists of equal-height brackets 91, the web of the equal-height bracket 91 is located at the center of the box column wall panel, and four T-shaped steels 81 are arranged in a circle at 90° intervals, with the corresponding vertical plates 812 aligned with the web of the equal-height bracket 91 respectively.

[0048] like Figure 6 As shown, if the I-shaped bracket group 9 has equal-height brackets 91 and eccentric brackets 92, the web of the eccentric bracket 92 is not in the center position of the box column wall panel, the four T-shaped steels 81 are arranged non-circularly at 90° intervals, and the vertical plate 812 corresponding to the eccentric bracket 92 is aligned with the web of the eccentric bracket 92.

[0049] like Figure 7As shown, if the I-shaped bracket group 9 has equal-height brackets 91 and variable-step brackets 93, the webs of equal-height brackets 91 and variable-step brackets 93 are located at the center of the box-shaped column wall panel. The upper flanges of equal-height brackets 91 and variable-step brackets 93 are respectively provided with first inner partitions 7 and second inner partitions 10. The lower flanges of equal-height brackets 91 are respectively provided with first inner partitions 7 and second inner partitions 10. The lower flanges of variable-step brackets 93 are respectively provided with first inner partitions 7 and second inner partitions 10. The three first inner partitions 7 and second inner partitions 10 are fixedly connected by two T-shaped assemblies 8. The four T-shaped steels 81 are arranged in a circle at 90° intervals. The corresponding uprights 812 are aligned with the webs of equal-height brackets 91 and variable-step brackets 93.

[0050] like Figure 1 , Figure 8 , Figure 9 As shown, in a specific embodiment, the lower box column 2 has high requirements for structural strength. The lower box column 2 is provided with several tie members 11. The tie members 11 are used to tie and support the wall panels of the lower box column 2. The tie members 11 include several sets of connecting beams 111 arranged at equal intervals in height. Adjacent sets of connecting beams 111 are perpendicular to each other.

[0051] In one specific embodiment, the intermediate connecting beam 111 is fixedly connected to the wall panel of the lower box column 2 through a rectangular frame 12, the rectangular frame 12 having a rectangular hole in the middle, and the remaining connecting beams 111 are fixedly connected to the wall panel of the lower box column 2 through connecting plates 13.

[0052] In one specific embodiment, the connecting beam 111 is an angle steel structure, and a set includes two connecting beams 111. The connecting plate 13 is a trapezoidal steel plate structure. The two connecting beams 111 are distributed on both sides and do not obstruct the jacking path of the concrete.

[0053] In one specific embodiment, the two ends of the ring 72 extend equidistantly from the top and bottom surfaces of the first rectangular plate 71, and the two ends of the rectangular ring 102 extend equidistantly from the top and bottom surfaces of the second rectangular plate 101.

[0054] In one specific embodiment, the column base plate 4 is provided with four vent holes 41, which are respectively connected to the four spaces divided by the cross-shaped steel plate 6. The vent holes 41 enable the internal space of the box column to be connected to the outside world, thereby reducing pressure.

[0055] In one specific embodiment, the four corners of the first rectangular plate 71 and the second rectangular plate 101 are chamfered.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
