Description

Technical Field

[0001] This utility model relates to the field of steel structure factory building technology, and in particular to a steel beam structure for a large-span heavy steel structure factory building. Background Technology

[0002] Steel structure workshops mainly refer to workshops whose main load-bearing components are made of steel. Steel structure workshops are characterized by light weight, high strength, and large span. They have a short construction period and reduce investment costs accordingly. During the installation of steel structure workshops, due to the large span of the supports, certain supporting structures are required to support the steel structure workshops and ensure their stability.

[0003] Chinese Patent No. CN221298744U discloses a large-span steel structure factory building structure, including a roof and supporting columns. Four supporting columns are provided, each with a fixed sleeve at its upper end. Adjusting rods are fitted inside each of the four supporting columns. A first horizontal bar is fixedly connected to the upper end of every two adjusting rods, and a vertical bar is fixedly connected to the upper end of each of the two first horizontal bars. The upper end of the vertical bar is fixedly connected to the roof, and fixed plates are provided on both sides of the vertical bar. A second horizontal bar is fixedly connected between the two first horizontal bars, and a rotating seat is fixedly connected to the upper end of the second horizontal bar. An electric push rod is rotatably connected to the upper end of the rotating seat, and a ventilation window is rotatably connected to one end of the electric push rod. By setting up supporting columns, fixed sleeves, first fixing bolts, and adjusting rods, the overall height can be easily adjusted, making it highly adaptable.

[0004] However, the above technical solution has the following shortcomings: the ventilation window in the proposed solution needs to be driven by an electric push rod, and the exchange speed between the air inside the factory and the outside is affected by the outside air flow rate. The interior space of a large-span factory is huge, and the air exchange speed is difficult to meet the ventilation needs of the factory. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a large-span heavy steel structure steel beam structure for factory buildings. This structure improves the air exchange speed between the factory building and the outside by setting up a layered bottom and top canopy and installing a bidirectional fan between the bottom and top canopy to accelerate air flow.

[0006] The technical solution of this utility model, a steel beam structure for a large-span heavy steel structure factory building, includes: four support columns, each with a threaded column, the four support columns being paired, each pair of support columns having a crossbeam, two frames arranged side by side on the two crossbeams, the two ends of the two frames respectively abutting against the four threaded columns, and multiple placement blocks b evenly arranged on the two frames; one connecting seat on each of the two crossbeams, each connecting seat having a top rod, and a canopy on the two top rods; and a main beam set on the two connecting seats, the main beam having multiple placement blocks a and multiple bidirectional fans evenly arranged, multiple support rods corresponding to each of the multiple placement blocks a and multiple placement blocks b, and two oppositely distributed bottom canopies laid on the multiple support rods.

[0007] Preferably, the base consists of a short side and a long side, with the short side perpendicular to the ground and the long side sloping downwards at one end. The short side is located below the ceiling.

[0008] Preferably, each of the multiple placement blocks a and placement blocks b has a placement slot.

[0009] Preferably, the canopy consists of a metal frame and multiple light-transmitting materials.

[0010] Preferably, heating components are laid on multiple support rods, and the heating components are connected to the base.

[0011] Preferably, reinforcing bars are provided on the support columns and crossbeams.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use of this utility model, after the main body of the factory building is assembled, two connecting seats, two top rods, and a roof are fixed to two crossbeams from bottom to top. At the same time, the main beam is also set on the two connecting seats. Multiple support rods and two bottom canopies are fixed in advance by multiple placement blocks a and multiple placement blocks b. The roof is distributed above the gap between the two bottom canopies, thereby ensuring the air exchange area between the factory building and the outside. At the same time, the bidirectional fan accelerates the air flow through the gap between the roof and the two bottom canopies, thereby increasing the air flow speed inside the factory building. All fixing methods in the process of building the factory building are common connection methods for steel structures, so they will not be described in detail. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-3 As shown in the figure, the steel beam structure of the large-span heavy steel structure factory building proposed in this embodiment includes support columns 1, connecting seats 6 and main beams 9. There are four support columns 1, and each of the four support columns 1 is provided with threaded columns 2. The four support columns 1 are paired up, and each pair of support columns 1 is provided with a crossbeam 3. Two frames 4 are arranged side by side on the two crossbeams 3. The two ends of the two frames 4 respectively abut against the four threaded columns 2. Multiple placement blocks b12 are evenly arranged on the two frames 4. There is one connecting seat 6 on each of the two crossbeams 3. Each of the two connecting seats 6 is provided with a top rod 7. The two top rods 7 are provided with a canopy 8. The main beam 9 is set on the two connecting seats 6. Multiple placement blocks a10 and multiple bidirectional fans are evenly arranged on the main beam 9. Multiple support rods 11 are arranged one-to-one on the multiple placement blocks a10 and multiple placement blocks b12. Two oppositely distributed bottom canopies 13 are laid on the multiple support rods 11.

[0020] In this embodiment, four support columns 1 are fixed to the ground, and then two crossbeams 3 are respectively set on two pairs of support columns 1. Two frames 4 are placed on two crossbeams 3. The two ends of the frame 4 are limited by the threaded column 2, and the top of the frame 4 is limited by the nut 5, so as to prevent the frame 4 from moving at will after placement, which facilitates subsequent fixing processing.

[0021] Two connecting seats 6, two top rods 7, and a canopy 8 are fixed to two crossbeams 3 from bottom to top. At the same time, the main beam 9 is also set on the two connecting seats 6. Multiple support rods 11 and two bottom canopies 13 are fixed in advance by multiple placement blocks a10 and multiple placement blocks b12. The canopy 8 is distributed above the gap between the two bottom canopies 13, thereby ensuring the air exchange area between the factory and the outside. At the same time, the bidirectional fan accelerates the air flow through the gap between the canopy 8 and the two bottom canopies 13, thereby increasing the air flow speed inside the factory. All the fixing methods in the forming process of this factory are common connection methods for steel structures, so they will not be described in detail.

[0022] Example 2

[0023] like Figure 1 and Figure 2As shown in the figure, the steel beam structure of the large-span heavy steel structure factory building proposed in this embodiment is different from that in embodiment one. In this embodiment, the base 13 is composed of a short side 131 and a long side 132. The short side 131 is perpendicular to the ground, and the long side 132 is inclined downward at one end. The short side is located below the roof 8. During rain, rainwater will fall on the long side 132. Since the long side is in an inclined state, the rainwater will slide down to the ground under its own weight. If the wind blows the rainwater towards the gap between the base 13 and the roof 8, the short side will block the rainwater, thereby preventing the rainwater from falling into the factory building.

[0024] Multiple placement blocks a10 and b12 each have placement slots 101. The two ends of the support rod 11 are first placed into the two placement slots 101 to place multiple support rods 11 one by one. Then the support rod 11 is fixed to the placement blocks a10 and b12, thereby avoiding the danger to the personal safety of other workers who are fixing the support rod 11 while placing and welding the support rod 11.

[0025] Example 3

[0026] like Figure 1 and Figure 2 As shown in the figure, the steel beam structure of the large-span heavy steel structure factory building proposed in this embodiment is different from that in embodiment one. In this embodiment, the roof 8 is composed of a metal frame and multiple light-transmitting materials. The metal frame is fixed to two top rods 7, and the light-transmitting materials can be made of tempered glass or other materials to improve the visibility of the factory building during the day.

[0027] Heating components are laid on multiple support rods 11 and connected to the base 13. The heating components can be made of electrically connected resistance wires and control devices, while the base 13 is made of steel structure. In snowy weather, the resistance wires can be used to heat the base 13 to melt the snow, thereby preventing the factory from collapsing under the weight of heavy snow.

[0028] Reinforcing rods 14 are installed on the support column 1 and the crossbeam 3. The reinforcing rods 14 are distributed at a 45-degree angle, thereby improving the stability of the steel structure factory building through a triangular structure.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
