Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a short column component for steel structure roofing. Background Technology

[0002] In the construction of steel structure roofs, in order to improve the vertical load (compressive resistance) and horizontal load (bending resistance) capacity of the roof, it is often necessary to install short columns extending out of the roof. These short columns are generally installed on the trusses or beams of the steel structure building and then extend out of the steel structure roof.

[0003] However, during the use of steel structure buildings, the steel structure will undergo certain deformation and displacement under the influence of the external environment. Gaps are likely to appear at the joints between the short columns and the roof. Rainwater can easily seep into the interior of the building through the joints between the short columns and the roof, causing roof leaks, damaging interior decoration and equipment, and affecting the normal use and structural safety of the building. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides a steel structure roof short column component.

[0005] This utility model application discloses a short column assembly for a steel structure roof. The assembly includes: a steel structure roof with a through hole; a short column, one end of which is located within the internal frame of the steel structure building, and the other end passing through the through hole and extending out of the steel structure roof; and a cover plate, comprising a cover plate body and a flange. The cover plate body covers the top surface of the short column, the through hole's orthographic projection onto the cover plate is located within the cover plate, and the flange surrounds the circumferential edge of the cover plate body, one end of which is connected to the cover plate body, and the other end extending towards the steel structure roof.

[0006] According to the steel structure roof short column assembly provided in the embodiments of this application, when rainwater falls from the sky, the rainwater first contacts the cover plate. Since the cover plate body completely covers the through hole, the occurrence of contact between the through hole and rainwater can be greatly reduced. By setting a downward folding flange, when the wind blows rainwater from the side of the short column, the flange can block the rainwater blown from the side, further reducing the occurrence of contact between the through hole and rainwater, thereby reducing the leakage at the through hole.

[0007] In one possible implementation of this application, the cover plate body extends obliquely toward the steel structure roof in a direction circumferentially outward from the central axis of the short column.

[0008] In one possible implementation of this application, the steel structure roof short column assembly further includes: a first insulation element, which covers the outer periphery of the short column.

[0009] In one possible implementation of this application, the steel structure roof short column assembly further includes: a waterproof component, which is disposed around the circumferential outer side of the first insulation component.

[0010] In one possible implementation of this application, the steel structure roof short column assembly further includes: a connecting plate located between the waterproof component and the first thermal insulation component, and the connecting plate being connected to the cover plate body; and fasteners sequentially passing through the waterproof component and the connecting plate.

[0011] In one possible implementation of this application, the steel structure roof short column assembly further includes: a pressure strip, the pressure strip covering the circumferential outer side of the connection between the connecting plate and the waterproof component, and the fasteners sequentially passing through the pressure strip, the waterproof component and the connecting plate.

[0012] In one possible implementation of this application, the connection points between the fastener and the waterproof component and the connecting plate are coated with sealant.

[0013] In one possible implementation of this application, the short column is a hollow tube, and a second heat-insulating element is provided inside the short column, which is filled inside the short column.

[0014] In one possible implementation of this application, the steel structure roof short column assembly further includes: a first vapor barrier membrane, which covers the outer peripheral surface of the short column.

[0015] In one possible implementation of this application, the steel structure roof short column assembly further includes: a second vapor barrier membrane, which covers the outer surface of the steel structure roof.

[0016] In one possible implementation of this application, the steel structure roof short column assembly further includes: a third insulation component, which covers the outer surface of the steel structure roof, and the third insulation component has a mating hole opposite to the through hole, the short column passing through the mating hole and extending out of the third insulation component.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0024] In the construction of steel structure roofs, in order to improve the vertical load (compressive resistance) and horizontal load (bending resistance) capacity of the roof, it is often necessary to install short columns extending out of the roof. These short columns are generally installed on the trusses or beams of the steel structure building and then extend out of the steel structure roof.

[0025] However, during the use of steel structure buildings, the steel structure will undergo certain deformation and displacement under the influence of the external environment. Gaps are likely to appear at the joints between the short columns and the roof. Rainwater can easily seep into the interior of the building through the joints between the short columns and the roof, causing roof leaks, damaging interior decoration and equipment, and affecting the normal use and structural safety of the building.

[0026] To resolve the above technical issues, please refer to Figure 1 This application provides a steel structure roof short column assembly 100, which may include a steel structure roof 101, short columns 102 and a cover plate.

[0027] The steel structure roof 101 can be a profiled steel sheet. Specifically, the steel structure roof 101 can be a corrugated profiled steel sheet, and the steel structure roof 101 is provided with through holes.

[0028] One end of the short column 102 is located in the internal frame of the steel structure building, and the other end passes through the through hole and extends out of the steel structure roof 101. Specifically, the lower end of the short column 102 is located on the crossbeam or truss of the steel structure building, and the upper end extends out of the steel structure roof 101. The lower end of the short column 102 is provided with a connecting flange 122, and the connection between the short column 102 and the crossbeam or truss is achieved by fastening bolts.

[0029] The cross-section of the through hole can be formed as a square hole, and the cross-section of the short column 102 is formed as a square that matches the through hole.

[0030] The cover plate includes a cover plate body 121 and a flange 122. The cover plate body 121 is placed on the top surface of the short column 102. The orthographic projection of the through hole on the cover plate is located inside the cover plate. That is, in the vertical direction, the cover plate completely covers the through hole. The flange 122 surrounds the axial edge of the cover plate body 121. One end of the flange 122 is connected to the cover plate body 121, and the other end extends toward the steel structure roof 101.

[0031] The cover plate body 121 and the flange 122 can be integrally formed.

[0032] In this way, when rainwater falls from the sky, it first comes into contact with the cover plate. Since the cover plate body 121 completely covers the through hole, the occurrence of contact between the through hole and rainwater can be greatly reduced. By setting the downward-folding flange 122, when the wind blows rainwater from the side of the short column 102, the flange 122 can block the rainwater blown from the side, further reducing the occurrence of contact between the through hole and rainwater, thereby reducing the occurrence of water leakage at the through hole.

[0033] In some embodiments of this application, the cover plate body 121 extends obliquely toward the steel structure roof 101 in a direction outward from the central axis of the short column 102.

[0034] In this way, rainwater dripping onto the cover plate body 121 will flow towards the outer periphery of the cover plate 121, preventing rainwater splashed from the cover plate body 121 from splashing into the through hole, thereby reducing the occurrence of water leakage in the steel structure roof 101.

[0035] The inclination angle between the cover plate body 121 and the horizontal plane can be between 3° and 8°. Specifically, the inclination angle can be 3°, 4°, 5°, 6°, 7° or 8°, etc.

[0036] Furthermore, in the direction of the cover plate body 121 toward the steel structure roof 101, the flange 122 can extend obliquely away from the short column 102, which can further reduce the occurrence of rainwater contact at the through hole location.

[0037] In some embodiments of this application, the outer periphery of the short column 102 may also be covered with a first thermal insulation element. Thus, by setting the thermal insulation material, rainwater can be blocked on the one hand, and on the other hand, the thermal insulation material can reduce the occurrence of condensation on the short column 102 due to temperature difference, further reducing the occurrence of water corrosion at the through hole and the short column 102, and reducing the occurrence of water leakage at the through hole.

[0038] The first insulation component may include two layers, namely an inner insulation component 131 and an outer insulation component 132. The inner insulation component 131 may be a 30mm thick rubber and plastic insulation material insulation layer, and the outer insulation component 132 may be a 100mm thick rock wool insulation layer.

[0039] Furthermore, the steel structure roof short column assembly 100 may also include a waterproof component 140, which surrounds the outer periphery of the first insulation component and may also cover the outer side of the steel structure roof 101.

[0040] The waterproof component 140 can be a thermoplastic polyolefin waterproof membrane, and the thickness of the waterproof membrane can be selected as 1.5mm. By setting the waterproof component 140, a layer of waterproof protection is provided for the entire exterior of the component.

[0041] Furthermore, the steel structure roof short column assembly 100 may also include a connecting plate 150 and a fastener 160, with the connecting plate 150 located between the waterproof component 140 and the first thermal insulation component, and the connecting plate 150 connected to the cover plate body 121.

[0042] Specifically, both the connecting plate 150 and the cover plate body 121 are steel plates. The connecting plate 150 is welded to the cover plate. Fasteners 160 are sequentially inserted into the waterproof component 140 and the connecting plate 150. Thus, by setting the connecting plate 150 and the fasteners 160, the waterproof component 140 is connected to the connecting plate 150, thereby fixing the waterproof component 140.

[0043] In the specific implementation process, the connecting plate 150 is arranged around the top of the short column 102 on the outer circumference, the waterproof component 140 extends to the connecting plate 150 and overlaps with the connecting plate 150, and the fastener 160 passes through the part where the connecting plate 150 and the waterproof component 140 overlap, wherein the fastener 160 can be a dovetail nail.

[0044] Furthermore, the steel structure roof short column assembly 100 may also include a pressure strip 170, which covers the circumferential outer side of the connection between the connecting plate 150 and the waterproof component 140. Fasteners 160 are sequentially inserted through the pressure strip 170, the waterproof component 140 and the connecting plate 150. Thus, by providing the pressure strip 170, the sealing at the connection between the waterproof component 140 and the connecting plate 150 can be further strengthened.

[0045] There can be multiple fasteners 160, and the multiple fasteners 160 are spaced apart in the circumferential direction of the short post 102.

[0046] After the fastener 160 is installed, sealant can be applied to the connection between the waterproof component 140 and the connecting plate 150 to further ensure the waterproof effect of the connection between the waterproof component 140 and the connecting plate 150 and reduce the occurrence of water leakage at the connection between the waterproof component 140 and the connecting plate 150.

[0047] Among them, fastener 160 can be a dovetail nail.

[0048] In some embodiments of this application, the short column 102 is a hollow tube, and a second insulation element 181 is provided inside the short column 102. The second insulation element 181 is filled inside the short column 102 and can be made of rock wool.

[0049] Therefore, by setting the second insulation component 181 to insulate the short column 102, the occurrence of condensation at the location of the short column 102 can be further reduced, the occurrence of water erosion of the short pipe can be reduced, and the service life of the steel structure roof short column assembly 100 can be extended.

[0050] In some embodiments of this application, the steel structure roof short column assembly 100 may further include a first vapor barrier 191, which covers the outer peripheral surface of the short column 102. Specifically, the first vapor barrier 191 may be a plastic film. To facilitate the construction of the first vapor barrier 191, the first vapor barrier 191 is pasted on the outer peripheral surface of the short column 102, and the first vapor barrier 191 is located inside the first insulation component.

[0051] In some embodiments of this application, the steel structure roof short column assembly 100 may further include a second vapor barrier 192, which covers the outer surface of the steel structure roof 101. Specifically, the second vapor barrier 192 may be a plastic film, and for ease of construction, the second vapor barrier 192 is pasted onto the steel structure roof 101.

[0052] In some embodiments of this application, the steel structure roof short column assembly 100 may further include a third insulation member 182, which covers the outer surface of the steel structure roof 101. The third insulation member 182 is provided with a mating hole opposite to the through hole. The short column 102 passes through the mating hole and extends out of the third insulation member 182.

[0053] In this way, by setting the third insulation component 182 to insulate the steel structure roof 101, the occurrence of condensation on the steel structure roof 101 is reduced, the possibility of water erosion on the steel structure roof 101 is reduced, and the occurrence of water leakage on the steel structure surface is reduced.

[0054] The third insulation component 182 can be 140mm thick rock wool, and the waterproof component 140 is laid on the outside of the third insulation component. The waterproof component 140, the third insulation component 182 and the steel structure roof 101 are fixedly connected by a non-perforated mechanical fixing method.

[0055] Specifically, the waterproof component 140, the third insulation component 182, and the steel structure roof 101 can be fixedly connected through multiple non-perforated mechanical fasteners.

[0056] The third insulation component 182 can be formed by stacking multiple layers of insulation materials.

[0057] In some embodiments of this application, the steel structure roof short column assembly 100 may further include round steel bars disposed at the upper end of the cover plate body 121.
