Description

Technical Field

[0001] This utility model relates to a device for raising the roof of a steel structure factory building, belonging to the technical field of steel structure factory building maintenance equipment. Background Technology

[0002] Steel structure workshops refer to buildings whose load-bearing components are made of steel. These include steel columns, steel beams, steel foundations, steel roof trusses, and steel roofs. In recent years, the production volume, variety, and performance of various types of steel used in the construction market have seen significant development. Steel structure workshops, due to their fast construction speed, high load-bearing capacity, overall rigidity, and good seismic performance, have gradually replaced heavy reinforced concrete structures in industrial plant design and have become widely used. Steel structure workshops can also be divided into light and heavy steel structure workshops. Heavy steel structure workshops in steel enterprises include steelmaking workshops, rolling mills, and large-scale smelting workshops. These workshops are characterized by large-tonnage cranes, high load-bearing capacity, complex structures, and are generally permanent structures that are not easily modified. Another type of steel structure workshop is the light steel structure workshop. These workshops often use portal frame structures, with roofs and walls made of profiled steel composite panels. Due to their light weight, low steel consumption, and fast construction speed, they have been widely used in steel enterprises and other industries. In actual production, it often happens that the original height of a light steel structure factory building becomes unsuitable due to changes in production processes or functional alterations, requiring reconstruction. Reconstruction increases construction costs significantly. If the original roof structure of the light steel structure factory building can be preserved while raising the existing roof, construction costs can be greatly reduced, thus lowering the company's production costs. This is a problem that the company's technical personnel need to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for raising the roof of a light steel structure factory building. This device can conveniently and quickly raise the roof of a light steel structure factory building, avoid reconstruction, reduce reconstruction time and materials, save construction costs, and reduce the production costs of enterprises.

[0004] The technical solution to the above technical problem is:

[0005] A device for raising the roof of a lightweight steel structure factory building includes a fixed column, a sliding column, column collars, and a hand-operated hoist. The fixed column and the sliding column are located inside the side support columns of the lightweight steel structure factory building. The lower end of the fixed column is fixedly connected to the ground by anchor bolts. The upper end of the sliding column is welded to the crossbeam of the lightweight steel structure factory building. The sliding column is parallel to the fixed column, and the lower part of the sliding column overlaps with the upper part of the fixed column. Multiple column collars are sequentially fitted onto the overlapping part of the sliding column and the fixed column. The two sides of the sliding column are in sliding engagement with the fixed column and the column collars, respectively. The upper end of the hand-operated hoist is fixedly connected to the top of the fixed column by a hook, and the lower end of the hand-operated hoist is fixedly connected to the bottom of the sliding column.

[0006] In the aforementioned device for raising the roof of a lightweight steel structure factory building, the column collar is a U-shaped ring, and the two sides of the U-shaped ring of multiple column collars are welded to the two sides of the fixed column, respectively, and the sliding column is located inside the U-shaped ring of the column collar.

[0007] In the aforementioned device for raising the roof of a lightweight steel structure factory building, the length of the overlapping portion of the fixed column and the sliding column is greater than the raising height of the roof of the lightweight steel structure factory building, and a column collar is fitted on the overlapping portion of the lower end of the sliding column and the upper end of the fixed column after the sliding column is raised.

[0008] The aforementioned device for raising the roof of a lightweight steel structure factory building includes a height-increasing column added to the gap at the lower end of the side support column after the sliding column is raised. The lower end of the side support column is welded to the upper end of the height-increasing column, and the lower end of the height-increasing column is connected to the original side support column base.

[0009] The aforementioned device for raising the roof of a lightweight steel structure factory building comprises multiple sets of fixed columns, sliding columns, and column collars. These multiple sets of fixed columns, sliding columns, and column collars are installed one by one with the multiple side support columns of the lightweight steel structure factory building. Multiple hand-operated hoists are installed on the multiple fixed columns and sliding columns.

[0010] The beneficial effects of this utility model are:

[0011] The lower part of the sliding column overlaps with the upper part of the fixed column, allowing the sliding column to slide along the fixed column. The column collar constrains the sliding of the sliding column and the fixed column, preventing the sliding column from tilting. The two ends of the hand-operated hoist are fixedly connected to the top of the fixed column and the bottom of the sliding column, respectively. Pulling the hand-operated hoist can raise the sliding column, which in turn raises the roof of the lightweight steel structure factory building. After the roof of the lightweight steel structure factory building is raised, height-increasing columns can be added below the existing side support columns to increase the height of the side support columns.

[0012] This utility model has a simple structure and is easy to use. It can quickly and easily raise the roof of a light steel structure factory building, avoiding reconstruction, reducing reconstruction time and materials, saving construction costs, and lowering the production costs of enterprises.

[0014] Figure 2 This is a schematic diagram of the structure of the roof of a lightweight steel structure factory building after the present invention has been lifted.

[0015] The following are marked in the diagram: Roof 1, Horizontal beam 2, Side support column 3, Side support column base 4, Fixed column 5, Sliding column 6, Column collar 7, Hand chain hoist 8, Height-increasing column 9. Detailed Implementation

[0016] This utility model consists of a fixed column 5, a sliding column 6, a column collar 7, a hand-operated hoist 8, and a height-increasing column 9.

[0017] Figure 1 As shown, the fixed column 5 and the sliding column 6 are located inside the side support column 3 of the light steel structure factory building. The lower end of the fixed column 5 is fixedly connected to the ground by anchor bolts. The upper end of the sliding column 6 is welded to the crossbeam 2 of the light steel structure factory building. The sliding column 6 is parallel to the fixed column 5. The lower part of the sliding column 6 overlaps with the upper part of the fixed column 5. The length of the overlapping part is greater than the height of the roof 1 of the light steel structure factory building.

[0018] Figure 1 The diagram shows that multiple column collars 7 are sequentially fitted onto the overlapping portions of the sliding column 6 and the fixed column 5. The column collars 7 are U-shaped rings, and both sides of the U-shaped rings 7 are welded to both sides of the fixed column 5. The sliding column 6 is located inside the U-shaped rings of the column collars 7. A column collar 7 is also fitted onto the overlapping portion of the lower end of the raised sliding column 6 and the upper end of the fixed column 5. The sides of the sliding column 6 are in sliding engagement with both the fixed column 5 and the column collars 7.

[0019] Figure 1 The manual chain hoist 8 is shown to be fixedly connected to the top of the fixed column 5 via a hook, and its lower end is fixedly connected to the bottom of the sliding column 6. In use, pulling the manual chain hoist 8 will cause its lower end to lift the sliding column 6 upwards.

[0020] Figure 1As shown, the fixed column 5, sliding column 6, and column collar 7 of this utility model are in multiple sets. The multiple sets of fixed columns 5, sliding columns 6, and column collar 7 are respectively matched and installed with multiple side support columns 3 of the light steel structure factory building. Multiple hand chain hoists 8 are respectively installed on multiple fixed columns 5 and sliding columns 6. Pulling multiple hand chain hoists 8 simultaneously can raise the roof 1 of the light steel structure factory building, thereby achieving the purpose of raising the roof of the light steel structure factory building.

[0021] Figure 2 The display shows that after the sliding column 6 is raised, the gap at the lower end of the side support column 3 of the light steel structure factory building is filled with a height-increasing column 9. The lower end of the side support column 3 is welded to the upper end of the height-increasing column 9, and the lower end of the height-increasing column 9 is connected to the original side support column foot 4.

[0022] Figure 2 The usage process of this utility model is shown as follows:

[0023] First, install multiple sets of fixed columns 5, sliding columns 6 and column collars 7 one by one with multiple side support columns 3 of the light steel structure workshop. Install multiple hand chain hoists 8 on multiple fixed columns 5 and sliding columns 6, and keep the hand chain hoists 8 in a taut state.

[0024] Then, use an oxy-fuel cutter to cut the connection between the lower end of the multiple side support columns 3 and the side support column feet 4, so that the lower end of the multiple side support columns 3 is separated from the side support column feet 4.

[0025] Simultaneously pulling multiple hand-operated hoists 8 causes multiple side support columns 3 to rise, and the upper ends of the multiple side support columns 3 drive the roof 1 of the light steel structure factory building to rise as a whole through the crossbeam 2.

[0026] When the roof 1 rises to the predetermined height, stop pulling the hand chain hoist 8. At this time, the lower end of the sliding column 6 and the upper end of the fixed column 5 still overlap. The overlapping part is constrained by the column collar 7 to prevent the sliding column 6 from moving away from the fixed column 5 and causing the roof 1 to tilt.

[0027] Place the pre-prepared height-increasing columns 9 at the lower end of the raised side support columns 3 respectively, weld the lower end of the side support columns 3 to the upper end of the height-increasing columns 9, and weld the lower end of the height-increasing columns 9 to the original side support column feet 4.

[0028] Remove the multiple chain hoists 8, cut the upper ends of the multiple sliding columns 6 to the crossbeam 2 with an oxy-acetylene torch, remove the anchor bolts at the lower ends of the multiple fixed columns 5, and complete the overall raising of the roof 1 of the light steel structure factory building.

[0029] An embodiment of this utility model is as follows:

[0030] The fixed column 5 has a cross-sectional length of 400mm, a width of 400mm, and a height of 5m;

[0031] The sliding column 6 has a cross-sectional length of 400mm, a width of 400mm, and a height of 5m;
