Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a steel structure column-beam connection structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Because of its light weight, simple construction and strong resistance to deformation, it is particularly suitable for building large-span, super-high and super-heavy buildings, and is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] Existing steel structure column-beam connection nodes are generally connected by bolts or welding. Bolted connections require the use of a large number of auxiliary components, such as reinforcing plates and stiffeners, and require the installation of a large number of bolts. The installation operation is relatively complex, and the force is basically applied to the bolts, resulting in poor strength and stability of the node. Welding generally involves welding the end of the steel pipe beam to the side wall of the steel pipe column. The steel pipe beam cannot form an effective force transmission with the entire steel pipe column, resulting in poor seismic performance of the beam-column connection node. Under load, the node is prone to deformation or damage. At the same time, both of these connection methods make it difficult to position the steel pipe beam during installation, and the steel beam is prone to shaking and displacement during construction, which has some shortcomings in actual use. Utility Model Content

[0004] This utility model provides a steel structure column-beam connection structure, which aims to solve the problems of existing column-beam connections that are connected by bolts or welding, resulting in low connection point strength, easy deformation or damage at the joints under load, inconvenient positioning, and easy shaking and displacement of the steel beams during construction, which can affect welding and fastening.

[0005] This utility model is implemented as follows: a steel structure column-beam connection structure includes steel pipe columns and steel pipe beams. Each steel pipe column has a corbel extending through its upper part. One end of the corbel extends to the outside of the steel pipe column, and an opening is formed at the upper part of the outer end of the corbel. A connecting pipe is fixedly connected to both ends of the inner cavity of the steel pipe beam. When the steel pipe beam is placed, the connecting pipe is inserted downward through the opening into the inner cavity of the corbel and overlaps with the corbel.

[0006] It also includes a sealing plate, which is adapted to the specifications of the opening. After the steel pipe beam is installed in place, the sealing plate is welded to the opening to achieve sealing.

[0007] Preferably, a through hole is provided at the upper part of the steel pipe column, and the bracket is disposed in the inner cavity of the steel pipe column through the through hole.

[0008] Preferably, the portion of the corbel located within the inner cavity of the steel pipe column has a first grouting hole that penetrates both the upper and lower walls.

[0009] Preferably, a second grouting hole is provided at both ends of the top of the steel pipe beam.

[0010] Beneficial effects

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a steel column-beam connection structure by welding a corbel inside a steel pipe column. An opening is made at the upper part of the corbel's end, and connecting pipes extending from both ends of the steel pipe beam are welded on. When placing the steel pipe beam, the connecting pipes can be embedded into the corbel's inner cavity through the opening, and the corbel supports and positions the connecting pipes, ensuring that the end of the steel pipe beam is precisely aligned with the end of the corbel. This prevents the steel pipe beam from shaking or shifting, facilitating subsequent welding operations. Then, a sealing plate is welded to seal the opening, and the corbel and steel pipe beam are welded together to form a single unit. The steel pipe beam, corbel, and steel pipe column form a unified whole, providing better support for the steel pipe beam, resulting in better connection strength, greater stability, and better force transmission. It is less prone to deformation or damage under load, thus exhibiting higher reliability. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a steel structure column-beam connection structure, including a steel pipe column 1 and a steel pipe beam 3. Each steel pipe column 1 has a corbel 2 through its upper part. One end of the corbel 2 extends to the outside of the steel pipe column 1. An opening is opened at the upper part of the outer end of the corbel 2. A connecting pipe 4 is fixedly connected to both ends of the inner cavity of the steel pipe beam 3. The end of the connecting pipe 4 extends to the outside of the steel pipe beam 3. When the steel pipe beam 3 is placed, the connecting pipe 4 is inserted downward into the inner cavity of the corbel 2 through the opening and overlaps with the corbel 2.

[0017] The bracket 2 is connected and fixed to the steel pipe column 1 by welding, so that the two form a whole, which enables the bracket 2 and the steel pipe column 1 to effectively transmit force, so that the force acts on the whole of the steel pipe column 1.

[0018] The cross-sectional specifications of the corbel 2 and the steel pipe beam 3 are the same. They can both be made from the same steel pipe. After the steel pipe beam 3 is installed, they are welded together to form a whole.

[0019] Since both steel pipe columns 1 are equipped with brackets 2 that extend outward to a certain length, the length of the steel pipe beam 3 is less than the distance between the two steel pipe columns 1, which provides more room for movement during hoisting and makes it less restricted by the steel pipe columns 1.

[0020] The cross-section of the connecting pipe 4 is consistent with the cross-section of the steel pipe beam 3, and the outer ring size is matched with the inner ring size of the steel pipe beam 3, so that the outer wall of the connecting pipe 4 is in close contact with the inner wall of the steel pipe beam 3, and they are welded together to form a whole, thus achieving effective force transmission.

[0021] When installing the steel pipe beam 3, first use a hoisting device to lift the steel pipe beam 3 upwards above the two brackets 2, and then slowly lower it so that the connecting pipes 4 at both ends are aligned with the openings at the ends of the brackets 2, until it falls from the openings. At this time, the bottom of the connecting pipe 4 overlaps the bottom of the inner wall of the bracket 2, and the two side walls contact the two sides of the inner wall of the bracket 2. At this time, the brackets 2 support the connecting pipe 4, and thus support the steel pipe beam 3. It is no longer necessary for the hoisting device to continuously lift the steel pipe beam 3. The steel pipe beam 3 has been positioned and will not shake or shift, which facilitates subsequent welding processing.

[0022] It also includes a sealing plate 5, which is adapted to the specifications of the opening. After the steel pipe beam 3 is installed in place, the sealing plate 5 is welded to the opening to achieve sealing.

[0023] In this embodiment, the opening is an n-shaped opening, which is formed by cutting off the top and upper parts of both sides of the end of the cow leg 2. The cut-off part can be used as the sealing plate 5, so the sealing plate 5 is also n-shaped.

[0024] The length of the part of the connecting pipe 4 extending out of the steel pipe beam 3 is adapted to the depth dimension of the opening on the end face of the bracket 2. The opening allows the connecting pipe 4 to pass through. When the steel pipe beam 3 is placed, the end of the connecting pipe 4 falls downward into the inner cavity of the bracket 2, and the bottom of the connecting pipe 4 overlaps the bottom of the inner wall of the bracket 2. The bracket 2 supports and positions the connecting pipe 4 and the steel pipe beam 3.

[0025] After the steel pipe beam 3 is placed in place, its two ends are welded and fixed to the end joints of the corbel 2 to form a complete whole.

[0026] After the steel pipe beam 3 is placed in place, the top and upper parts of the connecting pipe 4 located in the inner cavity of the corbel 2 are exposed and in an unconnected state. At this time, the sealing plate 5 is placed over the opening to cover the upper half of the connecting pipe 4. Then the sealing plate 5 is welded to the corbel 2 to form a whole, and the end of the connecting pipe 4 is wrapped inside.

[0027] Furthermore, a through hole is provided at the upper part of the steel pipe column 1, and the bracket 2 is disposed in the inner cavity of the steel pipe column 1 through the through hole.

[0028] In this embodiment, a through hole adapted to the cross-sectional size of the bracket 2 is opened laterally on the steel pipe column 1. The main body of the bracket 2 is located in the through hole, with one end flush with the inner side of the steel pipe column 1 and fixed by welding. Alternatively, the through hole penetrates the opposite side walls of the steel pipe column 1, with one end of the bracket 2 located in the through hole flush with the outer surface of the steel pipe column 1 and fixed by welding, and the other end protruding. The junction of its side wall and the side wall of the steel pipe column 1 is fixed by welding, so that the bracket 2 and the steel pipe column 1 are fully connected, and the force on the bracket 2 acts on the entire steel pipe column 1, rather than on a certain side wall.

[0029] Furthermore, the portion of the corbel 2 located within the inner cavity of the steel pipe column 1 has a first grouting hole 21 that penetrates both the upper and lower walls.

[0030] In this embodiment, after the steel structure is installed, grouting is required inside the steel pipe. In order to prevent the corbel 2 from blocking the flow of mortar, a first grouting hole 21 is opened on the corbel 2 so that the mortar can flow and fill the inside of the steel pipe column.

[0031] Furthermore, a second grouting hole 31 is provided at both ends of the top of the steel pipe beam 3.

[0032] In this embodiment, the second grouting hole 31 is used to grout into the steel pipe beam 3.

[0033] In this embodiment, only one corbel 2 is set on the steel pipe beam 1. The corbel 2 has an opening at one end and the other end can be flat or closed. This embodiment is applicable to the case where only one steel pipe beam 3 is installed on a steel pipe column 1.

[0034] In another embodiment, in some cases, two symmetrical steel pipe beams 3 are installed on the steel pipe column 1. In this case, the through holes on the steel pipe column 1 penetrate the opposite side walls, and both ends of the bracket 2 extend to the outside of the steel pipe 1 (not shown in the figure). Both ends of the bracket 2 are provided with openings and are equipped with two sealing plates 5, so that both ends of a connecting pipe 2 can be connected to the two symmetrical steel pipe beams 3 respectively.

[0035] In another embodiment, in some cases, a steel pipe beam 3 is connected to each side of a certain height of the steel pipe column 1. In this case, two through holes are formed in the steel pipe column 1, penetrating through the four side walls of the steel pipe column 1. The middle parts of the two corbels 2 are respectively provided with fitting grooves from the upper and lower sides, and the fitting grooves respectively extend to the bottom and the top of the inner wall, so that the two corbels 2 can be fitted into a cross shape. Then, the two corbels 2 are respectively inserted into a through hole and spliced (during this process, the overall height of the two is slightly greater than the height of one corbel 2 itself, so the height of one through hole should be slightly higher than the height of the corbel 2). A cross-shaped corbel is formed in the inner cavity of the steel pipe column 1, and the joints of the two are welded and fixed and welded to the steel pipe column 1. The ends of the cross-shaped corbel respectively extend to the outside of the steel pipe column 1, and each end is respectively provided with an opening and a sealing plate 5, and four steel pipe beams 3 can be arranged at intervals of 90° on the same horizontal plane.

[0036] In addition, in the connection of the corner column (that is, two steel pipe beams 3 arranged in an "L" shape are connected to one steel pipe beam 1) and the side column (that is, three steel pipe beams arranged in a "丄" shape are connected to one steel pipe beam 1) with the steel pipe beam 3, on the basis of this embodiment, one or two corbels 2 can be shortened to form a structure with two ends in an "L" shape or three ends in a "丄" shape, and each end has an opening and a sealing plate, which are respectively used to connect with two or three steel pipe beams 3.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
