Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and relates to a connection structure between steel columns and reinforced concrete beams, especially a connection structure between steel columns and reinforced concrete beams in a fully indoor steel structure substation. Background Technology

[0002] According to the general design requirements of the State Grid, indoor substations should preferably adopt steel structures. Therefore, most of the indoor substation projects currently under construction are steel frame structures. According to the electrical layout requirements of the substation, a cable mezzanine is generally set up for cable routing. Thus, there are two ways to do the zero-meter level: one is to use steel structures for the beams and columns, and the floor slab is a non-composite floor slab with profiled steel sheet bottom formwork or a steel truss floor slab; the other is to set up a reinforced concrete structure on the zero-meter level, with the reinforced concrete beams connected to the steel structure columns.

[0003] In this region, it is customary to install reinforced concrete structures at the zero-meter level of substations. The following measures are taken to address the connection points between reinforced concrete beams and steel frame columns:

[0004] 1. I-shaped brackets are pre-installed on the steel columns, and the beam reinforcement is welded to the brackets;

[0005] 2. Sleeves are pre-installed on the steel columns, and the beam reinforcement is mechanically connected to the steel columns;

[0006] 3. The beam reinforcement bars are bent and directly welded to the steel columns during on-site construction;

[0007] 4. The steel column ends extend perpendicularly to the column steel plate, and the beam reinforcement is welded to the steel plate.

[0008] However, the above connection structure has the following drawbacks:

[0009] 1. Directly welding the reinforcing bars of reinforced concrete beams to steel columns will damage the steel column structure and create safety hazards.

[0010] 2. Pre-installing I-shaped brackets and sleeves on steel frame columns is a more reliable approach, but for special reinforced concrete beams with multiple rows of reinforcement, the above methods are not suitable.

[0011] 3. When the steel column extends out of the steel plate, the steel plate is too long due to the specified length of the weld seam of the reinforcing bar on the steel plate, which affects the setting of the reinforcing bar of the outer concrete column. This connection method is not feasible when multiple rows of reinforcing bars are set in the reinforced concrete beam.

[0012] Therefore, this utility model proposes a connection structure between steel columns and reinforced concrete beams in an all-indoor steel structure substation.

[0014] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a connection structure between steel columns and reinforced concrete beams in an all-indoor steel structure substation. By setting a steel plate at one end of the steel reinforcement of the reinforced concrete beam, the steel plate is directly inserted and welded into the channel structure of the C-shaped steel fixedly welded to the steel column. This can avoid damage to the structural steel column and is also suitable for situations where multiple rows of steel reinforcement are unavoidably arranged in the reinforced concrete beam. It is safe, reliable, and easy to construct.

[0015] The present invention solves its practical problem by adopting the following technical solution:

[0016] A fully indoor steel structure substation steel column and reinforced concrete beam connection structure includes: steel column, C-shaped steel, reinforced concrete beam, reinforcing bars and steel plate; at least one C-shaped steel is fixedly connected to the steel column; a steel plate is fixedly connected to one end of the reinforcing bar in the reinforced concrete beam; the steel plate is directly inserted and welded into the channel structure of the C-shaped steel.

[0017] Furthermore, one end of a row of transversely arranged reinforcing bars in the reinforced concrete beam is fixedly connected to the same steel plate.

[0018] Furthermore, when there are multiple rows of reinforcing bars in a reinforced concrete beam, the number of steel plates and C-shaped steels fixed to the steel columns should be adjusted according to the number of rows of reinforcing bars.

[0019] Furthermore, the C-shaped steel and steel column surfaces are coated with an anti-corrosion coating.

[0020] Advantages and beneficial effects of this utility model:

[0021] 1. This invention proposes a connection structure between steel columns and reinforced concrete beams in an all-indoor steel structure substation. The connection structure is arranged according to the arrangement of the reinforcing bars in the reinforced concrete beam. Before the concrete of the reinforced concrete beam is poured, the reinforcing bars with steel plates at one end are inserted and welded into the C-shaped steel channel structure on the steel column. This is convenient and quick, and is particularly suitable for situations with multiple rows of reinforcing bars in the reinforced concrete beam. It ensures the stability of the joint and the safety and reliability of the structure while reducing on-site welding work and improving work efficiency.

[0022] 2. This utility model proposes a connection structure between steel columns and reinforced concrete beams in an all-indoor steel structure substation, enabling safe and reliable on-site construction and avoiding any impact on the main structure. Firstly, based on the vertical positioning of each row of reinforcing bars 5 within the reinforced concrete beam, C-shaped steel 3 is welded to the steel column 1 in the factory according to requirements. During on-site construction, steel plates 4 are installed at the ends of each row of reinforcing bars 5. Before pouring the reinforced concrete beam 2, the steel plates at the ends of the reinforcing bars only need to be embedded into the grooves of the C-shaped steel 3 for fixation, avoiding welding work on each reinforcing bar at the beam and improving construction efficiency while ensuring the anchorage strength of the reinforcing bars.

[0029] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0030] A fully indoor steel structure substation with steel columns and reinforced concrete beams connecting them, such as... Figures 1 to 4 As shown, it includes: steel columns, C-shaped steel, reinforced concrete beams, reinforcing bars, and steel plates; at least one C-shaped steel is fixedly connected to the steel column; a steel plate is fixedly connected to one end of the reinforcing bar in the reinforced concrete beam; the steel plate is directly inserted and welded into the channel structure of the C-shaped steel.

[0031] In this embodiment, one end of a row of transversely arranged reinforcing bars in the reinforced concrete beam is fixedly connected to the same steel plate.

[0032] like Figure 4 As shown, in this embodiment, the number of horizontally arranged steel bars in a row is 4.

[0033] In this embodiment, when there are multiple rows of reinforcing bars in the reinforced concrete beam, the number of steel plates and C-shaped steels fixedly connected to the steel columns are adjusted according to the number of rows of reinforcing bars.

[0034] like Figure 1-2 As shown, in this embodiment, the reinforced concrete beam has four rows of reinforcing bars.

[0035] In this embodiment, the C-shaped steel and the steel column are coated with an anti-corrosion coating.

[0036] In this embodiment, the C-shaped steel is positioned in the steel column after the steel structure manufacturer has familiarized himself with the drawings, and the connection and anti-corrosion treatment of the C-shaped steel and the steel column are completed in the factory, reducing on-site welding and anti-corrosion work.

[0037] The novel innovation of this utility model lies in:

[0038] This utility model proposes a connection structure between steel columns and reinforced concrete beams in an all-indoor steel structure substation. The connection structure is arranged according to the arrangement of the reinforcing bars in the reinforced concrete beam. During the pouring of the reinforced concrete beam, the reinforcing bars with steel plates are inserted and welded into the C-shaped steel on the steel column. This is convenient and quick, and is particularly suitable for situations where there are multiple rows of reinforcing bars in the reinforced concrete beam. The C-shaped steel can be positioned and welded before leaving the factory, reducing on-site welding work. Thus, while ensuring the stability of the joint and the safety and reliability of the structure, it reduces on-site welding work and improves work efficiency.

[0039] Mainly includes:

[0040] 1. Steel structure substation with steel columns and concrete beams connected by a plate-type connection structure;

[0043] 4. It reduces on-site welding work, which is beneficial for low-carbon and environmental protection.

[0044] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model includes, but is not limited to, the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
