Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0026] The internal gutter on the roof of an industrial factory building is generally placed above the steel beam and below the purlins on both sides. The depth of the internal gutter is less than the height difference between the steel beam and the purlin, so that rainwater can flow into the gutter along the roof on the purlin. When the rainfall is large, the depth of the internal gutter is insufficient and the risk of leakage is relatively high.
[0027] In order to solve the problem of insufficient depth of the traditional internal gutter, a variable-section gutter is provided below, in combination with Figure 1 , Figure 2 , Figure 3 .
[0028] The variable-section gutter includes: an on-beam groove section 1 and a between-beam groove section 2 that are detachably connected to each other in the length direction. The heights of the tops of the on-beam groove section 1 and the between-beam groove section 2 are the same, and the depth of the on-beam groove section 1 is less than the depth of the between-beam groove section 2.
[0029] The design of the between-beam groove section 2 adds an additional depth to the on-beam groove section 1, changing the problem of insufficient depth of the traditional internal gutter and easy leakage when the rainfall is large.
[0030] Specifically, in combination with Figure 1 and Figure 2。
[0031] The groove section 1 on the beam includes: a first web 11, first wing plates 12, first flange plates 13, and first hemming plates 14. The first web 11 is horizontally arranged, and the two first wing plates 12 are connected to both sides of the first web 11. The first wing plates 12 extend vertically upward or obliquely upward. The two first flange plates 13 are respectively connected to the top edges of the two first wing plates 12, and the first flange plates 13 extend horizontally away from the first wing plates 12. The two first hemming plates 14 are respectively connected to the sides of the two first flange plates 13 away from the first wing plates 12, and the first hemming plates 14 extend vertically downward or obliquely downward.
[0032] The groove section 2 between the beams includes: a second web 21, second wing plates 22, second flange plates 23, and second hemming plates 24. The second web 21 is horizontally arranged, and the two second wing plates 22 are connected to both sides of the second web 21. The second wing plates 22 extend vertically upward or obliquely upward. The two second flange plates 23 are respectively connected to the top edges of the two second wing plates 22, and the second flange plates 23 extend horizontally away from the second wing plates 22. The two second hemming plates 24 are respectively connected to the sides of the two second flange plates 23 away from the second wing plates 22, and the second hemming plates 24 extend vertically downward or obliquely downward.
[0033] In this embodiment, the first flange plate 13 and the first hemming plate 14 are used to form a hook for the groove section 1 on the beam to hook the purlin 5, and the second flange plate 23 and the second hemming plate 24 are used to form a hook for the groove section 2 between the beams to hook the purlin 5. The structures of the groove section 1 on the beam and the groove section 2 between the beams are the same or slightly different, and the difference between them depends on the inclination angles of the first wing plate 12, the second wing plate 22, the first hemming plate 14, and the second hemming plate 24.
[0034] Combined with Figure 3 , the groove section 1 on the beam and the groove section 2 between the beams are connected to the steel beam 4 by bolts 3 or welding. The splicing seam between the groove section 1 on the beam and the groove section 2 between the beams is sealed with a waterproof adhesive layer, which is not shown in the figure. The waterproof adhesive layer is usually adhered to the splicing seam between the groove section 1 on the beam and the groove section 2 between the beams after being melted by spray welding technology.
[0035] Regarding drainage, since the bottom of the groove section 1 on the beam is higher than the bottom of the groove section 2 between the beams, that is, the first web 11 is higher than the second web 21, the accumulated water inside the groove section 1 on the beam will flow smoothly into the inside of the groove section 2 between the beams, while the accumulated water in the groove section 2 between the two groove sections 1 on the beam cannot be discharged smoothly.
[0036] In one embodiment, not shown in the figure, a drain pipe is connected to the gap between the groove section 1 on the beam and the groove section 2 between the beams, so that the accumulated water inside the groove section 2 between the beams is discharged from both ends of the groove section 2 between the beams.
[0037] In another embodiment, not shown in the figure, a sealing structure is provided between the groove section 1 on the beam and the groove section 2 between the beams to seal the gap between the groove section 1 on the beam and the groove section 2 between the beams, and a drainage hole is also provided at the bottom of the groove section 2 between the beams, and the drainage hole is used to connect a drainage pipe to discharge the accumulated water in the groove section 2 between the beams into the drainage ditch below the ground.
[0038] In another embodiment, in combination Figure 3 , Figure 4 and Figure 5 .
[0039] Both ends of the second web 21 are tilted upward.
[0040] This design enables the second web 21 and the second wing plate 22 to form a three-dimensional trapezoidal or rectangular water storage tank. The second web 21 is also provided with a drainage hole (not shown in the figure), which is used to connect a drainage pipe to discharge the accumulated water in the inter-beam groove section 2 into the drainage ditch below the ground.
[0041] The manufacturing method of the second web 21 with both ends warped upward is as follows:
[0042] At both ends of the inter-beam groove section 2, the connecting parts of the second web 21 and the second wing plate 22 are cut, and then the second web 21 is bent upward so that the two ends of the second web 21 are warped upward, and then the two sides of the warped second web 21 and the inner wall of the second wing plate 22 are welded to form a three-dimensional trapezoidal or three-dimensional rectangular water storage tank.
[0043] The above-mentioned manufacturing method can be executed by a low-cost sheet metal process. As long as the water level inside the groove section 2 between beams does not exceed the height difference between the groove section 2 between beams and the groove section 1 on beams, there will be no water leakage between the groove section 1 on beams and the groove section 2 between beams. Moreover, as long as the depth of the groove section 1 on beams is reduced, the height difference between the groove section 2 between beams and the groove section 1 on beams can be reduced, thereby increasing the water storage depth of the groove section 2 between beams. Compared with the embodiment of completely sealing the gap between the groove section 1 on beams and the groove section 2 between beams, the production process of this embodiment is simple and the cost is low.
[0044] In this embodiment, the groove section 2 between beams also reserves a portion for connecting the steel beam 4. Figure 5 After the two ends of the second web 21 are tilted up, the two ends of the second wing plate 22 are partially located below the second web 21. This part of the second wing plate 22 does not participate in water storage, and bolt holes can be set at will. Then, the steel beam 4 is connected through the steel beam attachment 41 and the bolt 3. This design enables the groove section 2 between beams to replace the tie rod, thereby reducing the construction cost of the steel structure plant. The tie rod refers to the horizontal rod connecting two adjacent steel beams in the steel structure plant, which is usually made of steel pipe.
[0045] On the other hand, the width of the first web 11 is smaller than that of the second web 21, such that the first flange 12 is inserted between the two second flanges 22, and the edges at both ends of the second web 21 abut against the bottom of the first web 11.
[0046] This design enables the groove section 1 on the beam to pour accumulated water into the interior of the inter-beam groove section 2.
[0047] Furthermore, the first flange plate 13 is butted against the second flange plate 23, and the first hemming plate 14 is butted against the second hemming plate 24. Alternatively, the first flange plate 13 is placed above the second flange plate 23, and the first hemming plate 14 is placed outside the second hemming plate 24.
[0048] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the embodiments of the present invention.
