Description

Technical Field

[0001] The utility model relates to the technical field of clinker warehouse grid frames, in particular to a steel frame structure. Background Art

[0002] Cement clinker is a semi-finished product of cement. It is a block-like substance formed by high-temperature burning of raw materials such as limestone and clay. Cement clinker is mixed with some additives in a certain proportion and then ground into cement.

[0003] The cement clinker silo is a warehouse for storing cement clinker. The bottom of the clinker silo is a concrete silo structure, in which cement clinker is stored. The top of the clinker silo is a steel structure roof house, which is located above the silo to prevent rain and snow from soaking the silo wall and prevent the cement clinker in the silo from getting damp or contaminated. A conveying corridor is provided on the roof house to connect to the kiln head for preparing cement clinker. The cement clinker is transported from the kiln head to the roof house through the zipper machine in the conveying corridor, and then falls from the unloading port of the roof house into the silo below for storage. In order to ensure that the cement clinker is not eroded by rain and snow in harsh environments, the steel frame structure of the roof house needs to be sufficiently sealed in design.

[0004] For example, in the prior art, "A bolt ball grid structure for a clinker silo" (publication number: CN114482268) discloses a steel frame structure for a cement clinker silo, which solves the common problems of water leakage and dust emission in silos by setting connecting steel and specific supports at the connection between the bottom of the grid of the silo roof and the top of the silo grid, and using rock wool and edge parts to seal the gaps connected. However, the prior art still has the following technical problems:

[0005] As the outlet of the clinker storage is in the open air, there is no shelter above the roof room, and the connection gap between the top grid and the side wall grid of the roof room has not been leak-proofed. As a result, when encountering extreme weather such as heavy rain or heavy snow, rain and snow can easily penetrate into the wall of the roof room through the connection gap between the top grid and the side wall grid of the roof room, causing water leakage in the roof room or wall erosion. In more serious cases, rainwater will seep into the silo below the roof room, causing the cement clinker to clump and become unusable. Utility Model Content

[0006] The utility model provides a steel frame structure, which can solve the problem that the existing clinker warehouse grid frame cannot prevent rain and snow from penetrating into the wall through the connection gap between the top grid frame and the side wall grid frame of the warehouse roof, causing the warehouse roof to leak and causing the cement clinker in the silo to agglomerate and become unusable.

[0007] The present application provides the following technical solutions: a steel frame structure, comprising a silo grid, a plurality of support columns fixed above the silo grid, a floor slab fixed above the support columns, and a roof grid fixed above the floor slab, wherein the roof grid comprises a side wall grid fixed on the floor slab and a top grid fixed on the side wall grid, side wall panels are fixed between the side wall grids, and top panels are fixed between the top grids;

[0008] A sealing member is fixedly connected at the connection gap between the top panel and the side wall panel, and the sealing member comprises an inclined plate, a flashing plate and a vertical plate which are fixedly connected in sequence, the inclined plate is fixed on the top panel, and the vertical plate is fixed on the side wall panel;

[0009] The flashing plate is L-shaped, and includes an integrally formed vertical section and a horizontal section. The upper end of the vertical section is fixed to the inclined plate, and the end of the horizontal section away from the vertical section is fixed to the upper end of the vertical plate. A groove is provided on the horizontal section, and a drainage hole is opened at the bottom of the groove.

[0010] Beneficial effects:

[0011] 1. By setting a seal at the connection gap between the top grid and the side wall grid, when it rains or snows, if rain or snow seeps in from the gap between the top panel and the inclined plate of the seal, it will flow along the vertical section into the groove of the horizontal section and quickly drain downward along the drainage hole at the bottom of the groove, reducing the possibility of water accumulation, thereby preventing rain or snow water from infiltrating into the wall of the side wall panel of the roof room and then infiltrating into the silo under the roof room, preventing cement clinker from getting damp and agglomerated and becoming unusable.

[0012] 2. The L-shaped flashing design, in which the vertical section is fixed to the inclined plate and the horizontal section is fixed to the vertical plate, provides better structural stability and support, while facilitating quick installation and positioning by construction workers.

[0013] Furthermore, the contact surface gap between the inclined plate and the top panel and the contact surface gap between the vertical plate and the side wall panel are coated with sealant.

[0014] Beneficial effect: The sealant can seal the gap between the seal and the contact surface between the top panel and the side wall panel, further improving the sealing performance between the top panel and the side wall panel.

[0015] Furthermore, the side wall grid comprises a plurality of outer wall columns evenly distributed along the circumference and vertically fixed on the floor slab, and the side wall panel is fixed between adjacent outer wall columns.

[0016] Beneficial effect: The outer wall columns form the supporting skeleton of the side wall grid, which is used to fix the side wall panels, form an enclosure for the roof room, resist the external environmental load, and protect the internal components of the roof room from being damaged.

[0017] Furthermore, the top grid comprises a plurality of roof beams evenly distributed along the circumference, the top panel is fixed between adjacent roof beams, one end of the roof beam is fixed to the top of the outer wall column, and the other end of the roof beam is gathered together and fixed with a connecting seat.

[0018] Beneficial effect: The roof beam forms the supporting skeleton of the top grid, supporting the top panel, thereby protecting the interior of the roof room from rain and snow.

[0019] Furthermore, a roof ring beam is fixed on the top of the outer wall column. The roof ring beam is an I-beam. The roof ring beam is erected between the tops of adjacent outer wall columns. The lower end of the roof ring beam is fixed to the upper end of the outer wall column, and the side of the roof ring beam is fixed to the roof beam.

[0020] Beneficial effects: The ring beam is used to connect and fix the outer wall columns and the roof beams. The use of I-beams in the ring beam can improve strength and enhance stability.

[0021] Furthermore, the connecting seat includes a bottom plate, a top plate and a plurality of ribs fixed between the bottom plate and the top plate, the ribs are evenly distributed along the circumference, and a clamping plate for connecting and fixing is provided between the upper end of the roof beam and the ribs.

[0022] Beneficial effect: The connecting seat serves as a supporting point of the roof beam, connects and fixes the top ends of multiple roof beams, and ensures the stability of the roof beam.

[0023] Furthermore, a plurality of angle steels are fixed on the outer wall columns and the roof beams, side wall strips are fixed by screws between the angle steels on adjacent outer wall columns, and the side wall panels are fixed on the side wall strips; top strips are fixed by screws between the angle steels on adjacent roof beams, and the top panels are fixed on the top strips.

[0024] Beneficial effect: The top and side wall strips are fixed to the angle steel by screws, which is conducive to quick disassembly and installation, and is convenient for quick replacement when the top panel and side wall panel are damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1

[0033] like Figures 1 to 5 As shown, a steel frame structure includes a silo grid, a plurality of support columns 4 fixed above the silo grid, a floor slab fixed above the support columns 4, and a roof grid fixed above the floor slab.

[0034] like Figure 1 As shown, the silo grid includes a support 1 fixed to the ground and a mesh steel frame welded to the support 1. The mesh steel frame is in a truncated cone shape (for the convenience of displaying the structure, Figure 1 2 is a half-section view of the entire structure), the mesh steel frame includes a plurality of steel balls 3 as connection nodes, and the steel balls 3 are fixed with steel pipes 2 to form a whole.

[0035] A plurality of support columns 4 are welded to the top of the mesh steel frame. In this embodiment, there are 16 support columns 4 which are evenly distributed in a circle, and the floor slab is erected above the support columns 4 .

[0036] The roof grid of the warehouse includes a side wall grid fixed on the floor slab and a top grid 6 fixed on the side wall grid.

[0037] like Figure 2 and 5 As shown, the side wall grid comprises a plurality of wall outer columns 11 vertically fixed on the floor slab and a side wall panel fixed between adjacent wall outer columns 11. The wall outer columns 11 are evenly distributed along the circumference. In this embodiment, there are 8 wall outer columns 11. A roof ring beam 23 is welded and fixed on the top of the wall outer columns 11. The roof ring beam 23 is an I-beam and is erected between the tops of adjacent wall outer columns 11. The lower end of the roof ring beam 23 is welded and fixed to the upper end of the wall outer column 11. A plurality of angle steels 8 are welded and fixed at equal heights on each wall outer column 11 in the vertical direction. A side wall bar 9 with a C-shaped cross section is erected between the angle steels 8 at equal heights of adjacent wall outer columns 11. The side wall bar 9 is fixed to the angle steel 8 by screws, and the side wall panel is connected to the side of the side wall bar 9 by bolts.

[0038] like Figure 2 and Figure 5 As shown, the top grid 6 includes a plurality of roof beams 10 arranged on the outer wall columns 11 and a top panel 61 fixed between adjacent roof beams 10. The roof beams 10 are I-beams. The roof beams 10 are evenly distributed along the circumference, and the number of the roof beams 10 is equal to the number of the outer wall columns 11. One end of the roof beam 10 is welded and fixed to the side of the roof ring beam 23. Figure 3 and Figure 4 As shown, the other ends of the roof beams 10 are gathered together and fixed with a connection seat, which includes a bottom plate 22, a top plate 20 and a plurality of ribs 21 welded and fixed between the bottom plate 22 and the top plate 20, the ribs 21 being evenly distributed along the circumference, and a clamping plate 19 is provided between the upper end of the roof beam 10 and the ribs 21, and the clamping plate 19 is provided with screw holes, so that the roof beam 10 and the ribs 21 can be connected and fixed by screws. A top ridge plate 18 is also screwed to the top of the top plate 20 panel to cover the gap at the top of the top panel 61. A plurality of angle steels 8 are welded at equal distances along the length direction on each roof beam 10. A top bar 9 with a C-shaped cross section is arranged between the angle steels 8 at equal circumferential positions between adjacent roof beams 10. The top bar 9 is fixed on the angle steels 8 by screws. The top panel 61 is connected to the top of the top bar 9 by bolts. A sealant 12 is applied to the gaps between all adjacent top panels 61 for sealing, so as to prevent rainwater from seeping into the roof room through the gaps.

[0039] like Figure 2 As shown, a seal is provided at the connection gap between the top panel 61 and the side wall panel, and the seal includes an integrally formed inclined plate 14, a flashboard and a vertical plate 17. The flashboard is L-shaped and includes a vertical section 15 and a horizontal section 16. The upper end of the vertical section 15 is fixed to the inclined plate 14, and the end of the horizontal section 16 away from the vertical section 15 is fixed to the upper end of the vertical plate 17. The horizontal section 16 is provided with a groove, and a drainage hole is opened at the bottom of the groove. The inclined plate 14 and the vertical plate 17 are respectively fixed to the top panel 61 and the side wall panel by screws. The contact surface gap between the inclined plate 14 and the top panel 61 and the contact surface gap between the vertical plate 17 and the side wall panel are coated with sealant 12.

[0040] The principle of this structure to prevent rainwater leakage is as follows:

[0041] When it rains or snows, since the top panel 61 has a certain slope, rainwater will flow along the top panel 61 to the position with lower slope. When it flows into the gap where the inclined plate 14 contacts the top panel 61, if rainwater seeps in from the gap, it will flow along the vertical section 15 into the groove of the horizontal section 16, and be discharged downward along the drainage hole at the bottom of the groove, thereby preventing rainwater or snow water from infiltrating into the wall of the side wall panel of the roof room and then infiltrating into the silo under the roof room, thereby preventing cement clinker from getting damp and agglomerated and becoming unusable.
