AI Technical Summary
When traditional load-bearing columns face high-rise buildings and natural disasters, the deformation of the steel bar skeleton causes the load-bearing load to be reduced, which cannot effectively support the building structure and is difficult to intuitively detect its performance.
The reinforced bar frame design is adopted that includes a skeleton base, annularly distributed longitudinal ribs, upper and lower spacing stirrups, support rib components and hook-pull structure. The support rib assembly loads the support force on the central vertical steel bar through the inner support stirrup and inclined support bar. The hook-pull structure pulls the steel bar frame in the concrete layer through the outer hook bar and inner hook bar to enhance its stability.
It improves the stability and deformation resistance of the load-bearing column, can maintain the stability of the building structure under high load and natural disaster conditions, and makes the detection of the steel skeleton more intuitive through design.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of load-bearing columns, in particular to a load-bearing column. Background Art
[0002] The load-bearing column is the supporting structure of the building structure, such as the piers of bridges, the pillars of high-rise buildings, etc. The load-bearing column is made of steel cages of different standards and concrete of different standards according to the different loads it bears during the load-bearing process.
[0003] For ordinary load-bearing column structures, the structural method mostly adopted for its steel frame is: the longitudinal steel bars distributed in a ring and the circular steel bars distributed up and down are tied together to form a columnar steel cage, and then the concrete structure is randomly poured to form a load-bearing column.
[0004] In actual use, the load-bearing columns of ordinary structures have great universal applicability and can be used in general structures such as houses, and the support has high stability. However, for large-scale building systems with many floors and a high total height, the load-bearing columns of traditional structures cannot effectively bear their large loads. In actual use, with the increase of actual years, the steel skeleton inside the column head gradually deforms as the performance of the material decreases, resulting in a decrease in the stability of its support. In the face of general natural disasters, such as earthquakes, the deformation of the steel skeleton causes its load-bearing load to decrease, and it can no longer effectively support the entire building structure.
[0005] Therefore, as the service life of the building increases, the load-bearing columns need to be regularly inspected, but it is difficult to intuitively and conveniently inspect the performance of the skeleton cast in the inner layer of concrete. Therefore, from the perspective of building safety, the traditional steel cage skeleton cannot effectively, safely and stably support the building structure after reaching a high service life, maintain the safety of the building structure, and resist earthquakes of a certain intensity. Utility Model Content
[0006] Based on the above background, the purpose of the utility model is to provide a load-bearing column.
[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:
[0008] A load-bearing column, comprising a load-bearing column body, wherein the load-bearing column body comprises a load-bearing column steel bar skeleton and a concrete pouring layer poured on the load-bearing column steel bar skeleton;

[0039] Example 1
[0040] like Figure 1-6 As shown, a load-bearing column includes a load-bearing column body, wherein the load-bearing column body includes a load-bearing column steel bar skeleton and a concrete casting layer cast on the load-bearing column steel bar skeleton 1.
[0041] In order to increase the supporting load capacity of the load-bearing column body, improve its supporting stability, and keep the building structure under relatively stable support for a long time, the load-bearing column steel frame 1 is structurally improved to improve its deformation resistance and increase its supporting strength.
[0042] Specifically, the load-bearing column steel bar skeleton 1 includes a skeleton base 4 (the transverse cross-section of the skeleton base 4 is in the shape of a circular ring).
[0043] The top of the frame base 4 is fixedly connected with a plurality of annularly distributed longitudinal bars 11 (the longitudinal bars 11 are steel bars with a marked size and welded to the frame base 4). According to the existing steel cage processing method, the outer side of the longitudinal bars 11 is tied with a plurality of stirrups 12 arranged at intervals up and down. The load-bearing column steel frame 1 also includes a plurality of support bar assemblies 2 arranged at intervals up and down and fixedly connected to the longitudinal bars 11. The support bar assemblies 2 are used to support the load-bearing column steel frame 1 from the internal cage cavity, thereby improving its ability to resist deformation after being subjected to high loads.
[0044] Specifically, the support bar assembly 2 includes an inner support hoop 13 fixedly connected to the inner side wall of the longitudinal bar 11 (the inner support hoop 13 is welded and fixed), and a plurality of oblique support bars 22 arranged obliquely upward are fixedly connected to the inner side wall of the inner support hoop 13. The oblique support bars 22 are welded obliquely upward, so that during the working process, the oblique support bars 22 obliquely support the cage structure of the load-bearing column reinforcement skeleton 1, and the supporting force is loaded on the central vertical reinforcement 21 (the support bar assembly 2 also includes the central vertical reinforcement 21 located in the central part of the load-bearing column reinforcement skeleton 1, and the support bar assembly is fixedly connected to the central vertical reinforcement 21 through the oblique support bars 22).
[0045] The central vertical steel bar 21 is made of steel bars with added standard treatment or steel pipes. The oblique support bars 22 are fixed by welding. The angle of the oblique support is 45 degrees. During use, the central vertical steel bar 21 is used as the central axis fulcrum to support the steel cage structure from bottom to top.
[0046] When the steel cage tends to deform after being compressed, the inner support stirrups 13 and the oblique support bars 22 prevent it from further deformation, thereby greatly increasing the stability of the entire load-bearing column steel frame 1.
[0047] The lower end of the central vertical steel bar 21 is fixedly connected to the frame base 4 through a plurality of oblique fixing bars 41. Specifically, the two ends of the oblique fixing bars 41 are welded to the central vertical steel bar 21 and the inner side wall of the frame base 4, respectively.
[0048] The above method is used to fix the central vertical steel bar 21. At the same time, because the upper end of the central vertical steel bar 21 is fixed to the inner support stirrup 13 at the upper end through the oblique support bar 22, the upper and lower ends are fixed.
[0049] Example 2
[0050] like Figure 1-6As shown, based on the structure of Example 1, the present embodiment has a hook-pull structure fixedly connected to the above-mentioned load-bearing column steel bar skeleton 1. When the load-bearing column steel bar skeleton 1 is poured with concrete, the hook-pull structure is hooked in the concrete pouring layer. Specifically, the hook-pull structure includes a plurality of hook-pull bars respectively fixedly connected to the longitudinal bars 11. Hook-pull bars 3 spaced apart from each other are welded on each longitudinal bar 11 to ensure that after the concrete layer is poured, the steel bar skeleton can be stably supported in the concrete layer.
[0051] Specifically, the end of the hook reinforcement 3 is integrally formed with a hook portion with a hook setting. The hook reinforcement 3 includes an outer hook reinforcement 31 welded to the outer side wall of the longitudinal reinforcement 11 and an inner hook reinforcement 32 welded to the inner side wall of the longitudinal reinforcement 11. Specifically, the ends of the outer hook reinforcement 31 and the inner hook reinforcement 32 are integrally formed with a hook portion with a hook setting upward.
[0052] After pouring, the outer hook bars 31 and the inner hook bars 32 hold the concrete structure, and in the pulling state, keep the entire load-bearing column in a state of high stability and ability to withstand high loads.
[0053] Example 3
[0054] like Figure 1-6 As shown, based on the structure of Example 1, in order to increase the stability between the steel skeleton and the poured concrete structure layer from the lower end position, the bottom of the skeleton base 4 is welded with a plurality of gripping and pulling components gripping the concrete pouring layer. The gripping and pulling components are used to keep the steel skeleton pulling the concrete structure layer from the lower end position.
[0055] Specifically, each gripping and pulling assembly includes a gripping and pulling column 5, on which a plurality of gripping steel bar column heads 51 are welded. A rectangular concave surface is respectively provided on the side walls of the gripping and pulling column 5, on which the gripping steel bar column heads 51 are welded. The length of the gripping steel bar column heads 51 is 3 cm.
[0056] During the working process, after the concrete structure layer is poured, the steel bar column head 51 is gripped in the concrete layer. The advantage of this method is that it increases the connection stability between the entire steel bar and the concrete structure layer, especially in the event of an earthquake, and keeps it from loosening with the concrete structure layer.
[0057] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
