Description

Technical Field

[0001] The utility model relates to the technical field of existing concrete column reconstruction, in particular to a dumbbell-shaped reinforced concrete column. Background Art

[0002] Reinforced concrete columns are columns made of reinforced concrete. They are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic structures. They are often used as floor pillars, bridge piers, foundation columns, towers, and truss compression rods.

[0003] Traditional reinforced concrete columns are rectangular column structures. In industrial plants, there are many forklifts coming and going, and during operation, the corners of reinforced concrete columns are often damaged. As a result, the concrete corners fall off, and the steel bars (main force-bearing bars) on the sides leak out, causing the steel bars to rust, affecting the structural strength and service life of the concrete columns, and the durability is poor. In addition, because the operating crane is often replaced and the width of the newly replaced crane increases, the cross-sectional area of ​​the traditional reinforced concrete column is larger and cannot meet the operating requirements of the new crane. It can be seen that the traditional concrete column cannot meet the structural strength requirements, has poor durability, and its own cross-section is large, which cannot meet the site requirements for the operation of larger equipment.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0027] Combination Figures 1 to 4 As shown, the dumbbell-shaped reinforced concrete column provided by the embodiment of the utility model includes a bottom column 1, a top column 2 and an avoidance section 3. Specifically, the top column 2, the avoidance section 3 and the bottom column 1 are arranged in sequence from top to bottom. The avoidance section 3 includes an avoidance column 31 for connecting the top column 2 and the bottom column 1, wherein the avoidance column 31 is integrally formed with the top column 2 and the bottom column 1 to increase the structural strength. The side of the avoidance column 31 is a planar structure, which is convenient for the installation of subsequent structures.

[0028] The corresponding two sides of the avoidance column 31 are respectively provided with a load-bearing part 32, and the top and bottom of the load-bearing part 32 are respectively connected to the steel bars 4 on the top column 2 and the steel bars 4 on the bottom column 1, so that the force at the top can be transmitted to the load-bearing part 32 through the top column 2, and then transmitted to the bottom column 1, ensuring the stable transmission of the force, so that the dumbbell-shaped reinforced concrete column can provide sufficient supporting force. Among them, the two load-bearing parts 32 are located on the inner side of the steel bars 4 on the two corresponding sides of the bottom column 1 and the top column 2. This design method makes the cross-sectional area of ​​the avoidance section 3 smaller, and the top column 2, the avoidance section 3 and the bottom column 1 can form a dumbbell shape, providing a larger space for the use of the equipment. It can be understood that the load-bearing part 32 of the present application is supported by a hard material, such as stainless steel, to ensure its own structural strength and force transmission effect.

[0029] The dumbbell-shaped reinforced concrete column provided by the utility model is provided with an avoidance section 3 at a preset position to reduce the cross-sectional area at the position of the avoidance section 3, provide a larger space for the site, meet the site requirements for the operation of larger-sized equipment, and reduce the collision between the equipment and the reinforced concrete column 4. At the same time, the load-bearing part 32 can increase the structural strength of the reinforced concrete column 4 at the position that is easy to scratch. Even if an operating error occurs, it is the equipment that scratches the load-bearing part 32, avoiding the phenomenon of damaging the reinforced concrete column 4, thereby increasing the durability of the reinforced concrete column 4.

[0030] In some embodiments, in combination Figure 1 and Figure 2 As shown, the load-bearing part 32 includes two first steel plates 321 and a second steel plate 322 arranged on the side of the avoidance column 31, wherein one of the first steel plates 321 is used to connect with the steel bars 4 on the top column 2, and the other first steel plate 321 is used to connect with the steel bars 4 on the bottom column 1, and both ends of the second steel plate 322 are respectively connected to the two first steel plates 321, and the second steel plate 322 is located on the side of the first steel plate 321 facing the avoidance column 31.

[0031] Specifically, the first steel plate 321 is connected to the steel bars 4 on the top column 2 and the steel bars 4 on the bottom column 1 by welding, and the two first steel plates 321 are also connected to the two ends of the second steel plate 322 by welding to increase the firmness of the connection. The second steel plate 322 is located on the inner side of the first steel plate 321, so that the distance between the side of the second steel plate 322 and the side of the bottom column 1 and the top column 2 is large enough, further providing a clearance space for the movement of the equipment.

[0032] In some embodiments, in combination Figures 1 to 4 As shown, the thickness of the first steel plate 321 is greater than the thickness of the second steel plate 322 .

[0033] like Figure 4 As shown, the first steel plate 321 with a larger thickness has sufficient structural strength to ensure the welding effect of the first steel plate 321 and the steel bars 4 on the top column 2 and the steel bars 4 on the bottom column 1, and at the same time, can effectively transmit the force from the steel bars 4 on the top column 2. Figure 4 As shown, the thickness of the second steel plate 322 is relatively small, but it can ensure its own structural strength and force transmission effect. In addition, the second steel plate 322 reduces its own structural thickness, can reduce the space occupied in the horizontal direction, and further provide avoidance space for the movement of the equipment.

[0034] In some embodiments, Figure 1 As shown, a transition section 323 is provided at the connection between the first steel plate 321 and the second steel plate 322 .

[0035] With this design, the force on the first steel plate 321 at the top can be stably transmitted to the second steel plate 322 through the transition section 323, and the force received by the second steel plate 322 can be stably transmitted to the first steel plate 321 at the bottom through the transition section 323, thereby ensuring the stability of force transmission.

[0036] The cross section of the transition section 323 may be a right triangle, and the right angle of the transition section 323 is welded at the connection between the first steel plate 321 and the second steel plate 322 to ensure stable transmission and combination of forces. Figures 1 to 4 As shown, the avoidance section 3 further includes two connecting portions 33 , and the two connecting portions 33 are respectively used to connect corresponding sides of the two load-bearing portions 32 .

[0037] In this design, the two connecting parts 33 are used to connect the two load-bearing parts 32 into a whole. The two load-bearing parts 32 and the two connecting parts 33 are wrapped around the avoidance column 31 to ensure the stability of force transmission and increase the load-bearing effect of the load-bearing part 32.

[0038] In some embodiments, when the load-bearing portion 32 is designed with two first steel plates 321 and one second steel plate 322, the connecting portion 33 connects the relatively arranged first steel plates 321 and second steel plates 322 of the two load-bearing portions 32 to ensure the connection effect.

[0039] In some embodiments, the connection portion 33 includes two side plates 331 disposed on the side of the avoidance column 31 , and a plurality of gusset plates 332 for connecting the two side plates 331 , and the two side plates 331 are respectively connected to the two load-bearing portions 32 .

[0040] Specifically, both side plates 331 extend in the vertical direction, and one side of the side plate 331 is welded to the load-bearing part 32, specifically, the first steel plate 321 and the second steel plate 322 of the load-bearing part 32. A plurality of gusset plates 332 are provided, and the plurality of gusset plates 332 extend in the horizontal direction, and the plurality of gusset plates 332 are spaced apart in the vertical direction, so as to ensure the connection effect of the two relatively arranged side plates 331, and further ensure the connection effect of the two load-bearing parts 32.

[0041] In some embodiments, in combination Figure 1 and Figure 2 As shown, the top of the side plate 331 extends upward from the load-bearing portion 32, and the top extended end of the side plate 331 is connected to the top column 2, and the bottom of the side plate 331 extends downward from the load-bearing portion 32, and the bottom extended end of the side plate 331 is connected to the bottom column 1.

[0042] Under this design, the side panel 331 can also be connected to the top column 2 and the bottom column 1. At this time, the top column 2 and the bottom column 1 form an integral structure through the connecting part 33 of the side panel 331 and the load-bearing part 32, ensuring the load-bearing effect of the entire reinforced concrete column 4.

[0043] In some embodiments, continue to refer to Figure 1 and Figure 2 , the sizes of the two panels 332 at the edges are larger than the sizes of the other panels 332 .

[0044] Since the top and bottom surfaces of the side panel 331 also need to be connected to the top column 2 and the bottom column 1 , the top and bottom surfaces of the side panel 331 can be reinforced by a larger-sized fixing plate 332 to ensure the connection effect between the side panel 331 and the top column 2 and the bottom column 1 .

Specifically, the side of the avoidance column 31 is a planar structure or a nearly planar structure, which is convenient for the installation of subsequent components.

[0054] Under this design, the force is transmitted through the top column 2 in sequence to the first steel plate 321 at the top, the transition section 323 at the top, the second steel plate 322, the transition section 323 at the bottom, and the first steel plate 321 at the bottom and then transmitted to the bottom column 1, ensuring the stability of force transmission.
