Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to a concave-convex gutter system applied to a large-roof steel structure factory building. Background Art

[0002] At present, with the development of social economy, the scale of coal mines is constantly increasing, and large-span and large-column-spacing steel structure workshops are increasingly widely used in ground buildings of coal mines. The roof water catchment area of ​​this type of workshop is large, and the accumulated water is discharged only by the gutter, which will cause a large drainage volume of the gutter and a large calculated value of the gutter cross section. The gutter width is often limited by the column width, etc., and the gutter cross section can only be increased by increasing the gutter height to meet the drainage requirements. As the main water catchment area, the roof panel needs to be on the upper part of the gutter to ensure that the roof rainwater can be smoothly discharged into the gutter.

[0003] After the height of the gutter increases, the current conventional engineering practice is to increase the purlin section or raise the purlin to raise the roof panel so that rainwater enters the gutter. This practice often requires a large purlin section or purlin raising height when encountering a factory with a large span and a large column spacing. For example: for a double-span factory with a column spacing of 12m and a span of 30m, after the drainage professional designer calculates the catchment area, the gutter section needs to be 600×500mm to meet the drainage needs of the entire roof. The purlin height of the factory is 250mm, and the column end plate is 100mm higher than the column head. The purlin needs to be raised or the section increased by 350mm. Due to the large span factory, the number of purlins is very large. Raising the purlins by increasing the purlin section or related structural measures will, on the one hand, cause a significant increase in the amount of steel used for the purlins, and on the other hand, when the purlins are raised more, the stability is poor. Utility Model Content

[0004] The utility model aims to provide a concave-convex gutter system for use in large-roof steel structure workshops, which has the characteristics that rainwater on the roof can be smoothly discharged into the gutter without raising the roof panel, thus saving steel consumption and improving workshop stability.

[0006] The utility model is also characterized in that:

[0007] The steel column is H-shaped steel.

[0008] The gutter support beam includes a supporting angle steel, which is welded to the second flange of the steel column; a second gutter support steel beam is connected above the supporting angle steel by bolts; it also includes a first gutter support steel beam, which is welded to the connection node plate between the steel column and the steel beam; the first gutter support steel beam and the second gutter support steel beam are symmetrically arranged; and the concave and convex gutter is welded above the first gutter support steel beam and the second gutter support steel beam.

[0009] The gutter supporting steel, the first gutter supporting steel beam and the second gutter supporting steel beam are all channel steels.

[0010] It also includes a drainage pipe assembly, which includes a plurality of water branch pipes, which are arranged at the junction of the concave part of each gutter and the convex part of the gutter; one end of the water branch pipe is provided with a water outlet flush with the bottom of the concave part of the gutter, and the other end is connected to a main water collection pipe; the main water collection pipe is arranged parallel to the concave and convex gutter, the main water collection pipe is connected to a main water pipe, and the end of the main water pipe is connected to the ground drainage ditch; the main water pipe is arranged to fit the outer wall of the steel column.

[0011] The main water pipe is fixed under the roof beams through a number of round steels; the round steels are arranged at intervals.

[0012] The gutter joist height is lower than the steel column head height.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model is applied to the concave-convex gutter system in the large-roof steel structure factory building. The gutter is convex along the longitudinal direction of the factory building when it meets the factory building column. The convex size can be adjusted according to the sinking height of the gutter, which can not only ensure the gutter is connected, but also make the upper eaves of the gutter as low as possible while meeting the drainage section requirements of the gutter, so that the rainwater on the roof enters the gutter and is discharged without raising the roof panel.

[0015] 2. The utility model is applied to the concave-convex gutter system in the large-roof steel structure factory building, so that even if the gutter cross-section height is increased, the roof does not need to be raised, and the purlins supporting the roof only need to meet the force calculation requirements, and do not need to be enlarged or raised. For large-roof factories, it can greatly save steel and improve the stability of purlins, which not only improves the safety of the factory building but also saves the cost of factory building construction.

[0016] 3. The utility model is applied to the concave-convex gutter system in the large-roof steel structure factory building. The setting of the first gutter supporting steel beam and the second gutter supporting steel beam in the gutter support beam can fully ensure the stability of the gutter, and solve the problem that the lower right corner of the gutter is easily cracked. At the same time, the two steel beams are arranged along the longitudinal length of the factory building, which can play the role of top tie rods. The factory building does not need to set up additional tie rods to ensure longitudinal stability, which further reduces the amount of steel used in the factory building.
