Description

Technical Field

[0001] The present invention relates to the technical field of main steel structure, and more specifically to the technical field of steel structure column angle support. Background Art

[0002] When steel structure is used as the main building structure, in order to create a unique architectural design style, the building shape generally adopts irregular design. Due to the irregular design, the steel structure columns are not horizontal and vertical like the conventional main structure, but are inclined and bent;

[0003] How to ensure the stability and safety of the steel column supports, transfer the force of the main steel structure columns to the foundation project, avoid damage to the raft foundation due to improper setting of the main steel structure supports, and avoid quality problems such as cracking or leakage that affect normal use, has become an issue that needs to be solved urgently. Summary of the invention

[0004] The purpose of the present invention is to solve the above technical problems and provide a steel structure column angle support.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The present invention provides a steel structure column bent angle support, comprising a vertical steel pipe main body, a bent steel column main body arranged at the bottom of the vertical steel pipe main body, a steel insert assembly for connecting the vertical steel pipe main body and the bent steel column main body, a steel structure column arranged at the top of the bent steel column main body, an auxiliary installation and positioning assembly for connecting the bent steel column main body and the steel structure column, a bottom water stop disc arranged at the bottom of the vertical steel pipe main body, a basic disc arranged at the bottom of the bottom water stop disc, an L-shaped bent steel bar support assembly arranged at the bottom of the basic disc, and a plurality of water stop assemblies sleeved on the side wall of the vertical steel pipe main body, wherein the bottom of the L-shaped bent steel bar support assembly is a raft foundation.

[0007] In one embodiment, the vertical steel pipe body is provided with a first connecting bevel, and the bottom of the bent steel column body is provided with a second connecting bevel, the first connecting bevel is adapted to the second connecting bevel, and the two are connected by full welding;

[0008] A third connecting slope is arranged on the top of the bent steel column body, and a fourth connecting slope is arranged on the bottom of the steel structure column. The third connecting slope matches the fourth connecting slope, and the two are connected by full welding.

[0009] Specifically, the main body of the vertical steel pipe is cut from a cylindrical steel pipe, and its diameter and thickness are consistent with the steel structure column to be connected. It is an important component of the angle support, and the bottom is fully welded with the bottom water stop disc, and multiple water stop rings are distributed in the middle. The top of the main body of the vertical steel pipe is cut into an inclined surface according to the required inclination angle of the steel structure column, and then this inclined surface is used to connect with the corresponding inclined surface cut at the bottom of the main body of the bent steel column through full welding.

[0010] In addition, the size and thickness of the bent steel column body are the same as the thickness of the vertical steel pipe body. The inclination angle of the bottom of the bent steel column body and the top of the vertical steel pipe body, as well as the inclination angle of the connection between the bent steel column body and the top steel structure column are determined and cut according to the inclination angle of the steel structure column to be connected, and the corresponding connection is achieved through full welding.

[0011] In one embodiment, the steel insert assembly includes a plurality of steel inserts circumferentially welded at the connection between the vertical steel pipe body and the bent steel column body, and an auxiliary connection sleeve is provided on the outer side of the steel insert.

[0012] Specifically, the steel insert assembly is located between the vertical steel pipe body and the bent steel column body. The steel insert is used to reinforce the connection between the vertical steel pipe body and the bent steel column body to prevent the angle from changing, which may lead to stress concentration in the force transmitted by the steel structure column, deformation, fracture and other quality problems at the welding position. At the same time, the steel insert is used to facilitate the angle adjustment between the vertical steel pipe body and the bent steel column body and to assist in welding.

[0013] In one embodiment, the outer diameter of the base disc is larger than the outer diameter of the bottom water-stop disc, the bottom water-stop disc and the base disc are connected by welding, and the bottom water-stop disc and the base disc are concentrically arranged.

[0014] Specifically, the base disc is cut from a circular steel plate (the diameter and thickness are determined according to actual needs). The diameter of the base disc needs to be slightly larger than the water stop disc to facilitate welding and ensure the water stop area and increase the contact surface with the concrete pouring. The base disc provides a fixed foundation for the L-shaped bent steel bars at the bottom, and passes through this base disc.

[0015] In one embodiment, the bottom water-stop disc is sealed and arranged at the bottom of the vertical steel pipe body by welding, and the bottom water-stop disc is welded to the base disc by welding all around.

[0016] Specifically, the bottom water-stop disc is located at the lowest part of the vertical steel pipe body and plays a water-stopping role. Its diameter is slightly smaller than that of the foundation disc and it is welded to the foundation disc by welding on all sides. It achieves the sealing of the vertical steel pipe body to prevent leakage from the raft foundation. The groundwater directly leaks into the basement through the steel column body and affects the normal use of the basement.

[0017] In one embodiment, the L-shaped bent steel bar support assembly includes a plurality of L-shaped bent steel bars evenly distributed circumferentially at the bottom of a base disc, the longitudinal edge of each L-shaped bent steel bar is fixed to the bottom of the base disc, and the transverse edge of each L-shaped bent steel bar is arranged in the radial direction of the base disc.

[0018] Specifically, the L-shaped bent steel bar is located under the foundation disc and is bent into an L-shape from discarded steel bars. It mainly provides a supporting foundation for the foundation disc. It is generally composed of multiple L-shaped bent steel bars welded around the foundation disc. The size and model of the L-shaped steel bar are determined based on the weight of the angle support that needs to be borne and the impact force when pouring concrete.

[0019] Through this L-shaped bent steel bar, an effective support foundation can be provided for the foundation disc, avoiding direct contact between the entire bent angle support and the raft slab cushion layer. The L-shaped bent steel bar is used to reserve concrete pouring space to form a reinforced concrete protective layer, thereby further improving the bearing capacity and anti-leakage performance of the bent angle support.

[0020] In one embodiment, the water stop assembly includes a first water stop ring and a second water stop ring, the first water stop ring is located at the upper part of the vertical steel pipe body near the bottom, the thickness of the first water stop ring is the same as the thickness of the base disc, the inner ring diameter of the first water stop ring is larger than the outer diameter of the vertical steel pipe body, and the inner ring of the first water stop ring is welded to the outer wall of the vertical steel pipe body;

[0021] The second waterstop ring is located near the top of the vertical steel pipe body. The thickness of the second waterstop ring is the same as the thickness of the base disc. The inner ring diameter of the second waterstop ring is larger than the outer diameter of the vertical steel pipe body. The inner ring of the second waterstop ring is welded to the outer wall of the vertical steel pipe body.

[0022] Specifically, the first waterstop ring is located near the bottom of the vertical steel pipe body. It is cut from a steel plate and has a circular shape. The thickness of the first waterstop ring is the same as that of the base disc. The middle part is a hollow circle. The diameter of the hollow circle is slightly larger than the vertical steel pipe body, which is convenient for passing through the vertical steel pipe body and welding.

[0023] This first waterstop ring can effectively stop water and prevent water seepage caused by leakage in the raft foundation. On the other hand, this first waterstop ring can increase the contact area between the angle support and the raft concrete, which helps to decompose and transfer the force of the upper steel structure column to the raft foundation, ensuring that the raft will not be deformed or cracked directly due to stress.

[0024] The second water stop ring is located at the top of the cylindrical body. It is cut from a steel plate and is in the shape of a ring. Its thickness is the same as that of the base disc. The middle part is a hollow circle. The diameter of the hollow circle is slightly larger than that of the vertical steel pipe body, which is convenient for passing through the vertical steel pipe body and welding. Its function is the same as the first water stop ring, so I will not repeat it here.

[0025] It is specially noted that the number of waterstop rings of the waterstop assembly is determined comprehensively based on the thickness of the raft foundation and the weight of the steel structure columns that need to be borne, and the number is no less than one. The thicker the raft and the greater the force required to be borne, the more waterstop rings there are, and it is not limited to the first and second waterstop rings mentioned above.

[0026] In one embodiment, a plurality of stiffening ribs welded to the outer wall of the vertical steel pipe body are evenly distributed around the circumference at the bottom of the first water-stopping circular ring and the second water-stopping circular ring.

[0027] Specifically, the external dimensions of the stiffening ribs are cut on site according to actual needs, and are connected and fixed to the vertical steel pipe body and the water stop ring contact position by double-sided full welding; 4 are conventionally set, and generally no less than 3;

[0028] They are respectively located at the lower part of the first waterstop disc and the second waterstop disc, providing reinforcement for the first waterstop disc and the second waterstop disc, further dispersing the load transmitted from the steel structure column to the raft foundation, avoiding cracking of the raft due to excessive upper load, affecting leakage and affecting the normal use of the basement.

[0029] In one embodiment, the stiffening rib plate is a triangular steel plate, and the thickness of the stiffening rib plate is the same as the thickness of the first water-stopping disc or the second water-stopping disc.

[0030] In one embodiment, the auxiliary installation positioning assembly includes a plurality of auxiliary installation positioning blocks evenly distributed on the top of the bent steel pipe body in a circumferential manner, the bottom of each auxiliary installation positioning block extends out of the top of the bent steel pipe body, and the inner side of the top of each auxiliary installation positioning block contacts the outer surface of the steel structure column.

[0031] Specifically, the auxiliary installation positioning block is located between the bent steel pipe body to be connected and the steel structure column. Through this auxiliary installation positioning block, the upper steel structure column can be smoothly positioned and installed to prevent quality problems such as misalignment and failure to splice normally. At the same time, it helps to reinforce the connection parts of the bent steel pipe body and improve the bearing capacity of the vertical steel pipe body.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. This steel structure column angle support can effectively solve the effective connection between the main steel structure column and the angle support when the steel structure column needs to be designed into different inclination angles due to architectural shape. And through the application of accessory steel inserts, the anti-deformation performance of the steel support at the variable cross-section corner position is effectively improved to ensure structural safety.

[0034] 2. The application of water-stop rings improves the anti-seepage performance of the raft foundation. The application of stiffening ribs and auxiliary installation positioning blocks further improves the bearing capacity of the main steel structure columns, and effectively transfers the load of the upper rigid structure to the raft foundation.
