Description

Technical Field

[0001] The utility model relates to the technical field of steel structure factory buildings, in particular to a gantry flat grid closed factory building under limited space in an iron and steel plant area. Background Art

[0002] There are many steel structure factory buildings inside the iron and steel plant area. In the case where the single span does not exceed 50 m, the gantry flat grid structure is generally adopted. When the net clearance of the grid exceeds 20 m, the gantry flat grid mostly adopts double-support columns according to the span, net clearance height and load required by the factory building. The double-support columns have large bearing capacity, but large floor area, large required buried foundation volume and depth, and large occupied space.

[0003] When the gantry flat grid is in a limited space, such as when there are multiple railway tracks at the edge of the column, setting the foundation of the double columns will conflict with one of the railway tracks, occupy the position of the railway track, affect the train passage. When building a steel structure factory building with a large span, high net clearance and large load in a limited space, the volume of the building structure that the factory building needs to bear is huge, and there is serious interference with the surrounding buildings and structures, resulting in the damage of the load of the surrounding buildings or structures, affecting the use of the surrounding buildings and structures, and at the same time restricting the use conditions of the steel structure factory building and increasing the construction cost of the steel structure factory building. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a gantry flat grid closed factory building under limited space in an iron and steel plant area. The upper part of the vertical load-bearing of the grid closed factory building is connected to the roof grid composed of connecting rod members and bolt balls through the connecting rod members and bolt balls to form a grid structure factory building composed of connecting rod members and bolt balls. The grid structure shares the load of the steel structure factory building, reduces the load of the lower steel column, and a single steel column can support the overall steel structure factory building. The structure of the steel structure factory building is more compact, the bearing capacity of the steel column is reduced, the buried foundation volume and depth are correspondingly reduced, the interference between the surrounding buildings and structures is avoided, the construction cost is reduced, and it is suitable for construction in a site with limited space.

[0005] In order to achieve the above purpose, the utility model is realized by adopting the following technical solutions:

[0006] A gantry flat grid closed factory building under limited space in an iron and steel plant area, including vertical load-bearing and roof grid. The vertical load-bearing is divided into upper and lower sections. The lower section is a steel column, and the upper section is a grid structure composed of connecting rod members and bolt balls. The grid structure is arranged on the steel column through a connecting support. The roof grid is connected and composed of connecting rod members and bolt balls. The grid structure and the roof grid are connected through bolt balls and connecting rod members.

[0007] Further, concrete is poured inside the steel column.

[0008] Furthermore, shear studs are welded to the outer wall at the bottom end of the steel column, and longitudinal steel bars and stirrups are arranged on the outside of the steel column.

[0009] Furthermore, the longitudinal steel bars, stirrups and the steel column are poured together to form a short concrete-filled column.

[0010] Furthermore, a catwalk is provided on the roof space frame.

[0011] Furthermore, the surrounding of the enclosed factory building is enclosed by profiled steel sheets.

[0012] Furthermore, a fiberglass polyester flame-retardant daylighting board is provided on the roof space frame for enclosure.

[0013] Furthermore, wind columns are arranged between the steel columns.

[0014] Furthermore, the wind columns are made of H-shaped steel.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By adopting the force-bearing mode of combining a single steel column with a space frame structure, the vertical load-bearing is jointly completed by the steel column and the space frame structure. The space frame structure undertakes the load-bearing of the steel column, solving the problem of insufficient load-bearing capacity of a single steel column and the problem of being unable to arrange double steel columns for load-bearing in a limited space. The steel structure factory building has a more compact structure, the bearing capacity of the steel column is reduced, the volume and depth of the buried foundation are correspondingly reduced, avoiding interference between surrounding buildings and structures, and reducing the construction cost, being suitable for construction in a site with limited space.

Embodiment

[0042] As Figures 1 - 11 shown, multiple rows and columns of shear studs 21 are welded on the lower surface of the steel column 1. Positioning bolts 5-1 are embedded when tying the foundation beam steel bars. To ensure the accurate position of the positioning bolts 5-1, positioning steel plates 4-3 are welded on the upper surface of the pile cap beam steel bars. There are bolt reserved holes around the positioning steel plates 4-3, so that the positioning bolts 5-1 pass through the adjusting pads 4-2, and the upper and lower nuts 5-2 of the positioning bolts 5-1 are tightened to make the steel pads 4-1, adjusting pads 4-2 and positioning steel plates 4-3 fit tightly, and the positions of the positioning bolts 5-1 are accurate.

[0043] Fix the positioning bolt 5-1 with concrete 6. Arrange a circle of longitudinal steel bars 22 on the outside of the steel column 1, and arrange multiple stirrups 23 outside the longitudinal steel bars 22. After the outer longitudinal steel bars 22 and stirrups 23 are tied up and the bottom positioning bolt 5-1 is fixed in position, weld the steel column 1 to the positioning steel plate 4-3. After the steel column 1 is accurately welded and positioned, formwork is erected outside the longitudinal steel bars 22, and concrete 6 is poured to form a concrete-encased short column 20. The concrete-encased short column 20 completely wraps the longitudinal steel bars 22 and stirrups 23. When the steel column 1 leaves the factory, steel column stiffeners 7 and steel column concrete pouring ports 9 are reserved. An air vent 8 is reserved in the middle of the steel column stiffeners 7. After the concrete-encased short column 20 of the steel column 1 is poured, continue to pour concrete 6 into the steel column 1 through the steel column concrete pouring port 9 to enhance the counterweight and compressive capacity of the steel column 1.

[0044] After the concrete 6 inside the steel column 1 is poured, weld the pouring port 9 shut. At the same time, weld the steel column top plate 11 and the column top rib plate 10. Weld the support base plate 12 above the steel column top plate 11, weld the support rib plate 13 above the support base plate, and weld the support ball 14 above the support rib plate 13. The support base plate 12, support rib plate 13, and support ball 14 form the connection support 15 between the steel column 1 and the space grid structure.

[0045] The upper part of the vertical load-bearing is composed of connecting members 16 and bolt balls 17 to form a space grid structure 2. The connecting members 16 of the space grid structure 2 are connected to the support ball 14 of the connection support 15. The space grid structure 2 is connected to the steel column 1. The height of a single steel column 1 and the space grid structure 2 each account for half of the total height of the space grid factory building. The space grid structure 2 is connected to the roof space grid 3 through connecting members 16 and bolt balls 17. The space grid structure 2 bears the load of the factory building, reduces the load on the steel column 1, and a single steel column 1 can be used to carry a large-load factory building with a large span and a high clear height.

[0046] An anti-wind column 19 is arranged between two steel columns 1, and a maintenance catwalk 18 is arranged below the roof space grid 3.
