Description

Roof leak-proof structure and roof structure

technical field

The invention relates to the technical field of roof structures in structural houses, in particular to a roof leak-proof structure and a roof structure.

Background technique

The steel structure industrial workshop is usually composed of a steel structure foundation and a steel structure roof. The steel structure roof is composed of purlins arranged at intervals and roof panels fixed on the purlins. In use, considering the indoor ventilation and lighting conditions, it will be set on the roof panel. Ventilators, skylights or ventilation balls, etc.

As shown in FIG. 13, it is a steel structure roof structure, including inclined purlins 22 and roof panels 19, the highest point of the roof is the ridge line 5, and the roof panel 19 is the highest point at the ridge line 5, from the ridge line 5 When it is far from the ridge line 5, the height of the roof panel 19 gradually decreases, and a number of water guide troughs 20 are arranged on the roof panel 19 along the slope. Therefore, some protrusions 21 will be formed on the roof panel 19. Because the protrusions 21 are protruded above the roof panel 19, they will guide the flow of water in the water channel 20 of the roof panel 19. In rainy days, a large amount of water will accumulate in the gutter 20 located on the upslope end of the protrusion 21, which will cause corrosion to the sealing part of the upslope end of the protrusion 21 over time, resulting in water leakage on the roof.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

Example 1:

Referring to FIG. 1 , a roof leak-proof structure includes a deflector 1 arranged on the upslope end of the protrusion 21, the deflector 1 is provided with a diversion groove 2, and the diversion groove 2 is provided with an opening 3, the opening 3 is located at both ends of the diversion groove 2 (as shown in Figure 4), after the rainwater falls on the diversion plate 1, it will be collected in the diversion groove 2, and then flow away through the openings 3 on both sides of the diversion groove 2. The openings 3 are located on both sides of the protrusion 21 , so the rainwater on the deflector 1 can be guided to the roof panels 19 on both sides of the protrusion 21 through the guide groove 2 .

Among them, there are multiple diversion grooves 2, and the plurality of diversion grooves 2 are evenly distributed on the guide plate 1. The direction of the guide grooves 20 on the roof panel 19 is arranged along the slope direction. In this embodiment, the guide grooves 2 The length direction of the guide groove 20 is perpendicular to the direction of the guide groove 20, so that the rainwater flowing down the slope from the guide plate 1 can all fall into the guide groove 2 and flow away, and because the direction of the water flow in the guide groove 2 is consistent with the roof slope The direction is vertical, so the speed of the rainwater flowing on the guide plate 1 can be slowed down through the guide groove 2, so that the rainwater is less likely to splash on the protrusions 21 when the flow rate is too high. In the specific implementation process, the angle between the guide groove 2 and the water guide groove 20 can also be adjusted according to the actual situation, as long as the openings 3 at both ends of the guide groove 2 are located on the water guide groove 20 on both sides of the protrusion 21 It is enough to drain the rainwater left in the guide groove 2 to the water guide grooves 20 on both sides of the protrusion 21, so that water will not accumulate in the guide groove 2 on the upslope end of the protrusion 21. .

Referring to FIGS. 2 and 3 , in this embodiment, a plurality of guide plates 1 are provided, and adjacent guide plates 1 are mutually engaged to form a locking edge structure 8 . After overlapping, it can be bent and rolled in one direction to form the overlock structure 8 .

The fixing frame 7 is fixed on the purlin 22 at the upward slope end of the protrusion 21 , and the deflector 1 is fixed on the fixing frame 7 . In order to enhance the strength of the edge-locking structure 8 of the baffle 1, the fixing frame 7 at the edge-locking structure 8 is provided with a bracket 9 in the baffle. Between the two adjacent deflectors 1, the bracket 9 in the deflector has a bending structure consistent with the bending direction of the edge locking structure 8, so the adjacent two deflectors 1 are bent around the bracket 9 in the deflector Folding and crimping in the direction forms the locking edge structure 8 , and makes two adjacent baffles 1 locked on the bracket 9 in the baffle.

Referring to FIG. 4 , in order to prevent the baffle 1 itself from leaking water, in this embodiment, the baffle 1 adopts a color steel plate with a concealed buckle 11, so the baffle 1 is directly punched and formed with a concealed buckle 11 on the side of the baffle 1 facing the fixing frame 7 . By arranging the buckle 10 on the fixing frame 7, the deflector 1 can be connected with the buckle 10 through the hidden buckle 11. At this time, there is no installation hole on the deflector 1, so the waterproof effect is better. Since the buckle 10 is directly fixed on the fixing frame 7, and the fixing frame 7 has high strength and thick thickness, the buckle 10 is not easy to be detached from the fixing frame 7 during use, thereby making the connection between the deflector 1 and the fixing frame 7. Interconnection strength is higher. In use, a plurality of buckles 10 are evenly distributed on the fixing frame 7, so that the deflector 1 is not easy to fall off after installation, and is not easy to deform and shake after installation.

4, the fixing frame 7 is a fixing rod 71 fixed on the purlin 22, the fixing rod 71 is fixed along the length direction of the water guide 20, and the fixing rod 71 is fixed in the water guide 20 below the guide plate 1 When fixing the fixing rod 71, the fixing rod 71 is directly fixed on the purlin 22 below the deflector 1 by bolts. Because the purlin 22 has high structural strength and thick thickness, the fixing rod 71 can be firmly fixed. The surface of the fixing rod 71 facing the deflector 1 is set as a plane 12, and the buckle 10 is directly fixed on the plane 12 by bolts. When the water deflector 4 is engaged with the buckle 10, the plane 12 and the back of the water deflector 4 Fittingly, the water guide plate 4 is stably limited on the fixing rod 71 by the buckle 10 and the flat surface 12, and it is not easy to shake during use.

Referring to FIG. 4 , since the rainwater falling on the deflector 1 needs to flow out from the deflector 2 to the water deflector 20 , in order to prevent the rainwater from leaking into the house along the side of the deflector facing the house, a The opening 3 of the guide groove 2 is provided with a water guide plate 4, one end of the water guide plate 4 is connected to the guide plate 1, and the other end is located in the water guide groove 20, and the height of the water guide plate 4 is from the end of the guide plate 1. It gradually lowers to the end of the water guiding groove 20, so that the rainwater will be drained into the water guiding groove 20 along the water guiding plate 4, and the direction of the arrow in the figure is the direction of the water flow.

5, the end of the deflector 1 away from the protrusion 21 is located at the ridge line 5, and a ridge cover 6 is provided at the ridge line 5, so that the end of the deflector 1 located on the ridge line 5 is located at the ridge cover 6 and the ridge cover 6.
