Description

Technical Field

[0001] The utility model relates to the field of civil engineering, in particular to a support column. Background Art

[0002] In the construction of high-rise buildings, support columns are often used to support the load; steel skeletons are built into the support columns, and during construction, the connection between the steel skeletons and the intersecting beam reinforcements needs to be considered.

[0003] Currently, the steel skeletons and beam reinforcements usually have the following connection methods: 1. The reinforcement passing method: a certain number of reinforcement passing holes are arranged on the flanges and webs of the steel skeletons, so that the longitudinal reinforcements of the beams can directly pass through the steel skeletons without being truncated; 2. The connector method: a certain number of internal thread sleeves are welded on the flanges of the steel skeletons as connectors, and although the longitudinal reinforcements of the beams are not directly connected to the steel skeletons, they are tightly engaged with the internal thread sleeves.

[0004] However, for the above-mentioned reinforcement passing method and connector method, due to the need for precise operations such as drilling and positioning, socket connection and biting, the requirements for on-site construction accuracy are high. When multiple beams intersect with the same support column at the same position, there will be problems with difficult operations. Summary of the Utility Model

[0005] The utility model provides a support column to solve the problem of difficult operations caused by the high requirements for on-site construction accuracy in the existing reinforcement passing method and connector method.

[0012] The length direction of the cross beam is perpendicular to the length direction of the column body, and a plurality of groups of connection beam reinforcements arranged at intervals are distributed in the length direction of the cross beam. Each group of connection beam reinforcements corresponds to one group, and the ends of each group of connection beam reinforcements are fixedly arranged on the surface of the connection plate in the corresponding group.

[0013] Optionally, each group of the connecting beam reinforcements is arranged in layers, and the end length of the connecting beam reinforcements in the upper layer is greater than that of the connecting beam reinforcements in the lower layer.

At the connection position between the connecting plate in the non-first layer and the connecting beam reinforcement, an extended protrusion is provided. The protrusion is parallel to the cross-section of the column body. Among them, the longer the extension length of the protrusion of the connecting plate in the lower layer.

[0018] Optionally, the connecting plates in each group are arranged at intervals in the following manner:

[0019] Each of the connecting plates in each group is a concentric ring. The diameter of the connecting plate in the lower layer is greater than that of the connecting plate in the upper layer, and the longer the diameter of the connecting plate in the lower layer. The extra ring part of the connecting plate in the lower layer compared to the connecting plate in the upper layer is used to provide a connection position for the connecting beam reinforcement.

[0020] Optionally, the column body is a cross-shaped steel. Vertical reinforcements and stirrups are provided outside the column body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Although the accompanying drawings show exemplary embodiments of the present utility model, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present utility model can be understood more thoroughly and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0031] Referring to Figure 1 As shown, a support column provided by the present utility model is used for assembling with a cross beam 30, and includes a column body 10 and a connection mechanism 20; the connection mechanism 20 includes: a plurality of connection plates 21 stacked and arranged at intervals; the plurality of connection plates 21 are concentrically arranged; an installation hole is provided at the center of the connection plate 21, and the column body 10 is inserted into the installation hole and fixedly connected to the connection plate 21; the connection plate 21 is parallel to the cross section of the column body 10; all the connection plates 21 are divided into a plurality of groups 211; the plurality of groups 211 are spaced apart in the length direction X of the column body 10, and each group 211 includes a plurality of connection plates 21 arranged at intervals; the length direction of the cross beam 30 is perpendicular to the length direction of the column body 10, and a plurality of groups of connecting beam ribs 31 arranged at intervals are distributed in the length direction Y of the cross beam 30, each group of connecting beam ribs 31 corresponds to a group 211, and the ends of each group of connecting beam ribs 31 are fixedly arranged on the surface of the connection plate 21 in the corresponding group 211.

[0032] Specifically, as Figure 1 shown, an elevation cross-sectional view of a support column assembled with multiple cross beams 30 is shown, in which the connecting beam ribs 31 of the cross beam 30 are divided into upper and lower groups; the connection plates 21 are installed on the main body 10 of the support column, and the connection plates are divided into two groups 211. The interval between the two connection plate groups 211 is the same as the interval after the connection beam ribs 31 are grouped, so that each connection plate group 211 can be aligned with the corresponding group of connecting beam ribs 31.

[0033] During the construction of a building, support columns are an essential part. The support columns are assembled with crossbeams to form the framework of the building. The support columns can be reinforced concrete columns. When a large load-bearing capacity is required, steel bones are built into the support columns. Therefore, the connection problem between the steel bones and the beam bars of the intersecting crossbeams needs to be considered during assembly. The existing through-bar method and connector method in the prior art require relatively precise operations such as positioning and drilling, aligning and socketing, and threaded engagement to complete the connection. The on-site construction accuracy requirements are high. Especially when multiple crossbeams with grouped beam bars intersect at the same position of the support column, the related technologies cannot provide a more convenient construction solution. For this reason, the present utility model adopts the means of a connecting plate. First, the connecting plate is fixedly connected to the steel bone, and then the connecting beam bars of the crossbeam are fixedly connected to the connecting plate, so that the connecting beam bars and the steel bone are indirectly connected together, thereby realizing the intersection and connection of the crossbeam and the support column. At this time, during on-site construction, the connection between the connecting plate and the steel bone and the connection between the connecting plate and the connecting beam bars are mainly considered. For the connecting plate and the steel bone, only an installation hole corresponding to the steel bone needs to be opened in the center of the connecting plate, the steel bone is passed through the connecting plate, and the connecting plate is welded at the required position. For the connecting plate and the connecting beam bars, only the connecting beam bars need to be placed on the connecting plate along the length direction of the crossbeam, and the connecting beam bars and the connecting plate are welded to complete the fixed connection between the connecting plate and the connecting beam bars. This connection process omits the relatively precise operations in the related technologies, so it can significantly reduce the difficulty of on-site construction operations, reduce rework caused by construction errors, improve construction efficiency while ensuring construction quality, and during this connection process, the connecting beam bars of multiple crossbeams in different directions can be fixedly connected to the same connecting plate. Because the connecting plate is fixed relative to the support column steel bone and the connecting plate is parallel to the cross-section of the support column, a scheme for assembling multiple crossbeams in different directions on the same cross-section of the support column can be obtained. In addition, for the case where the crossbeam has multiple groups of connecting beam bars, the present utility model sets connecting plates in corresponding groups and at corresponding positions to ensure that each group of connecting beam bars has a placement position for welding.

[0034] In an embodiment of the present utility model, when the crossbeam and the support column are assembled, the end portions of the connecting beam bars of the crossbeam are directly placed on the annular connecting plate and welded, so that the connecting beam bars of multiple crossbeams can be arranged at different positions on the upper surface of the same connecting plate. For the case where the connecting beam bars are grouped, corresponding connecting plate groups are set, and the connecting beam bars are welded to the corresponding grouped connecting plates respectively. The above operations realize the assembly of multiple crossbeams with multiple groups of connecting beam bars and the support column at the same cross-section position, and eliminate the precise operations such as positioning and drilling and socketing engagement required in the related technologies during on-site construction, solving the problem of difficult operations in the related technologies.

[0035] Optionally, referring to Figure 1As shown, each group of connecting beam bars 31 is arranged in layers, and the end length of the upper-layer connecting beam bars is greater than that of the lower-layer connecting beam bars 31. The number of connecting plates 21 included in each group 211 is the same as the number of layers of the corresponding group of connecting beam bars 31. The ends of each connecting beam bar 31 are successively placed and welded on the upper surface of the corresponding connecting plate 21.

[0036] Specifically, as Figure 1 shown, there are two groups of connecting beam bars 31, upper and lower, arranged in each cross beam 30, and each group of connecting beam bars 31 is further arranged in upper and lower layers. In each group of connecting beam bars 31, the end length of the upper-layer connecting beam bars 31 is greater than that of the lower-layer connecting beam bars 31. Correspondingly, the connecting plate 21 is also provided with two groups 211, and each group 211 is also provided with two layers, that is Figure 1 the upper connecting plate 2111 and the lower connecting plate 2112 in . Among them, the upper connecting beam bars 31 with longer ends are placed and welded on the upper surface of the upper connecting plate 2111, and the lower connecting bars 31 with shorter end lengths are placed and welded on the upper surface of the lower connecting plate 2111. By setting layers for each group 211, a fixed connection position is provided for each layer of the layered connecting beam bars 31.

[0037] During the construction process, multiple groups of connecting beam bars are generally arranged in the cross beam to provide multiple connection positions with the support columns, ensuring that there are no gaps between the cross beam and the support columns, which may affect the stability of the connection between the cross beam and the support columns. At the same time, according to the magnitude of the load on each cross beam, each group of connecting beam bars is layered. Generally, the greater the load on the cross beam, the more layers there are in each group of connecting beam bars. Multiple connecting beam bars are arranged in parallel in each layer of connecting beam bars, and the number of parallel arrangements depends on the width of the cross beam.

[0038] Optionally, referring to Figure 1 , after each group of connecting beam bars 31 is layered, the first interval width between adjacent connecting beam bars 31 is the same, and the second interval width between adjacent connecting plates 21 in each group is the same. Figure 1 In , both the layering of the connecting beam bars 31 and the group 211 are divided into two layers, and there is only one interval, so Figure 1 is not shown in .

[0039] During construction, the connecting beam bars can be divided into multiple layers with equal spacing. In order to provide a fixed position for each layer of connecting beam bars, the corresponding group is also set to be multiple layers with equal spacing.

[0040] Optionally, referring to Figure 1 shown, the second interval width between adjacent connecting plates 21 in each group 211 is greater than the diameter of the connecting beam bars 31.

[0041] The width of the gap between adjacent connecting plates is greater than the diameter of the connecting beam reinforcement, allowing the connecting beam reinforcement to be inserted into the gap between adjacent connecting plates. During on-site construction, generally only the load in the gravity direction of the connecting beam reinforcement is considered. At this time, it is only necessary to place and weld the connecting beam reinforcement on the upper surface of the connecting plate to complete the connection between the connecting beam reinforcement and the support column. However, in some scenarios, the connecting beam reinforcement is subject to loads in two opposite directions in the gravity direction. At this time, the connecting beam reinforcement can be inserted into the gap of the connecting plate and welded to the adjacent connecting plate simultaneously to enhance the load-bearing capacity of the connecting beam reinforcement.

[0042] Optionally, referring to Figure 2 shown, a plan sectional view of a support column assembled with multiple cross beams 30 is presented. Among them, the connecting plates 21 in each group ( Figure 2 not shown in the figure) are spaced apart in the following manner: Each connecting plate 21 in each group Figure 2 not marked in the figure is an equal-diameter concentric ring. At the connection position between the connecting plate 21 of the non-first floor and the connecting beam reinforcement 31, an extended protrusion 22 is provided. The protrusion 22 is parallel to the cross-section of the column body 10. Among them, the extension length of the protrusion of the connecting plate in the lower layer is longer ( Figure 2 not shown in the figure).

[0043] During construction, circular connecting plates of the same specification can be used. When it is necessary to deal with the stratification of the connecting beam reinforcement, additional protrusions coplanar with the connecting plate are installed at the connection position between the connecting beam reinforcement and the connecting plate. In order to adapt to the outer contour of the column-beam assembly, the protrusions can be set as fan-shaped rings. For the convenience of placement and welding, the protrusions of the connecting plates after stratification will increase with the increase of the number of stratification layers, and the corresponding ends of the connecting beam reinforcement will become shorter with the increase of the number of stratification layers. The corresponding connecting beam reinforcements are sequentially placed on the protrusions of the corresponding connecting plates. Through the above method, each layer of connecting beam reinforcement has a corresponding placement and welding position, and the upper connecting plate will not block the welding position between the lower connecting plate and the connecting beam reinforcement, facilitating on-site construction operations.

[0044] Optionally, referring to Figure 1 shown, an elevation sectional view of a support column assembled with multiple cross beams 30 is presented. Among them, each connecting plate 21 in each group 211 is a concentric ring. The diameter of the lower connecting plate 2112 is greater than that of the upper connecting plate 2111, and the diameter of the connecting plate in the lower layer is longer ( Figure 1 not drawn in the figure). The extra ring part of the lower connecting plate 2112 compared to the upper connecting plate 2111 is used to provide a connection position for the connecting beam reinforcement 31.

[0045] During construction, circular connecting plates of different specifications can also be used. When it is necessary to deal with the layering of connecting beam reinforcements, the connecting plates are placed with a smaller upper part and a larger lower part like the tabletop of a frustum of a cone. To facilitate laying and welding, the diameter of the connecting plates after layering increases with the increase in the number of layers, and the end parts of the corresponding connecting beam reinforcements become shorter with the increase in the number of layers. The corresponding connecting beam reinforcements are successively laid on the extra circular ring parts of the corresponding connecting plates. Through the above method, each layer of connecting beam reinforcements has a corresponding laying and welding position, and the upper connecting plate will not block the welding position of the lower connecting plate and the connecting beam reinforcements, facilitating on-site construction operations.

[0046] It should be noted that in the present utility model, the shape of the connecting plate can also be rectangular, elliptical or triangular, that is, the present utility model does not limit the shape of the connecting plate. In the embodiments of the present utility model, in order to balance the load generated by each connecting beam reinforcement on the connecting plate after the connecting beam reinforcements of each cross beam are laid on the connecting plate, a circular ring-shaped connecting plate is selected; in addition, the thickness of a single connecting plate can be determined according to the diameter and quantity of the lapped connecting beam reinforcements, and the thickness of a single connecting plate has a positive correlation with the latter two.

[0047] Optionally, referring to Figure 2 As shown, the column body 10 is a cross-shaped steel, and vertical reinforcements 11 and stirrups 12 are arranged outside the column body 10. In a top view perspective, multiple vertical reinforcements 11 are arranged around and spaced apart with the center of the cross-section of the column body 10 as the center of the circle, and the stirrups 12 are arranged on the same side of the vertical reinforcements 11, and the stirrups 12 are fixedly connected to the vertical reinforcements 11.

[0048] The column body of the support column can be a cross-shaped steel, and the cross-shaped steel can provide good load-bearing capacity for the support column. The surrounding vertical reinforcements and the stirrups fixedly connected to the vertical reinforcements form the outer frame of the support column, and construction workers pour concrete according to the outer frame to shape the support column.

[0049] Optionally, referring to Figure 2 As shown, a reinforcing plate 13 is arranged at the connection between the wing plate opening of the column body 10 and the connecting mechanism 20. After the reinforcing plate 13 is connected to the connecting mechanism 20, it extends outward along the length direction X of the column body 10 ( Figure 2 not marked in the figure).

[0050] A reinforcing plate is welded at the connection between the wing plate opening of the column body and the connecting mechanism. The length of the reinforcing plate is the connection length between the column body and the connecting mechanism plus the length that the reinforcing plate extends outward along the length direction of the column body. The length that the reinforcing plate extends outward along the length direction of the column body can be set to 500 mm. Through the above method, the connection between the connecting mechanism and the column body can be strengthened.

[0051] Optionally, referring to Figure 1As shown, after the connecting plates 21 are stacked at intervals, through holes 24 are formed in the lower connecting plate 2112, and the vertical ribs 11 are arranged through the through holes 24.

[0052] When the connecting plate or the protrusion intersects with the vertical rib, a hole is formed at the intersection position on the connecting plate or the protrusion to avoid truncating the vertical rib and keep the vertical rib unobstructed.

[0053] Optionally, referring to Figure 1 As shown, the connecting mechanism 20 further includes stiffening ribs 23. The stiffening ribs 23 are arranged vertically and are spaced around the column body 10 at intervals. The upper end and the lower end of the stiffening ribs 23 are fixedly connected to the uppermost layer group and the lowermost layer group in the length direction X of the column body respectively.

[0054] Specifically, as Figure 1 shown, according to the positions of the connecting beam bars 31 of multiple cross beams placed on the connecting plates 21, a plurality of stiffening ribs 23 are arranged around the column body. The upper end of the stiffening rib is connected to the lower connecting plate 2112 of the upper layer group 211, and the lower end of the stiffening rib is connected to the lower connecting plate 2112 of the lower layer group 211. In this way, the overall stiffness of the connecting plate is ensured.

[0055] It should be noted that in another embodiment of the present invention, the upper end of the stiffening rib can be connected to the uppermost connecting plate of the uppermost layer group, and the lower end of the stiffening rib can be connected to the lowermost connecting plate of the lowermost layer group, so as to determine the connection positions of the upper and lower ends of the stiffening rib according to the needs of on-site construction.

[0056] Optionally, referring to Figure 1 As shown, when the stiffening rib 23 passes vertically through the connecting plate 21, a groove is formed at the intersection position of the stiffening rib and the connecting plate ( Figure 1 not shown in the figure), and the stiffening rib 23 is clamped into the groove and welded at the intersection position of the stiffening rib and the connecting plate.

[0057] The stiffening ribs are arranged according to the length direction of the column body, so they will pass through the connecting plates between the ends of the stiffening ribs. When the stiffening rib needs to pass through the connecting plate, a groove can be formed on the connecting plate at the intersection position of the stiffening rib and the connecting plate. After the groove is formed, the stiffening rib is clamped into the groove and welded to ensure that the stiffening rib is not truncated by the connecting plate.

[0058] In the embodiment of the present invention, by arranging annular connecting plates at intervals on the column body of the support column, welding positions are provided for multi-layer connecting beam bars, meeting the assembly requirements when the connecting beam bars of the cross beam are stratified; by changing the sizes of the connecting plates in each group, the influence of the upper connecting plate on the connection position of the lower connecting plate and the connecting beam bars when the connecting beam bars are connected to the connecting plates is avoided; through the reinforcing plate, the connection strength between the column body and the connecting mechanism is increased; through the stiffening ribs, the overall stiffness of the connecting plate is ensured.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present utility model can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or more.
