Description

Technical Field

[0001] The utility model relates to the technical field of building leakage prevention, in particular to a roof leakage blocking structure which is easy to adjust. Background Art

[0002] In the field of steel structure construction, light steel structure roof design is widely used, especially for large-span steel structure workshops. Light steel structure roof has the characteristics of convenient and fast construction, beautiful shape, and wide application. During the construction of steel structure buildings, it is necessary to consider the impact of thermal expansion and contraction of roof panels on steel structure buildings. Therefore, in traditional technology, expansion joints are usually reserved between the roof panels on both sides of the ridge of steel structure buildings, and polyurethane foam fillers are filled in the expansion joints for waterproofing. However, after the building is used for a long time, the polyurethane foam filler is easily damaged by external erosion, resulting in water leakage at the expansion joints.

[0003] In addition, some building structures will install cover plates above the expansion joints, which are fixed to the roof panels on both sides with self-tapping screws to achieve waterproofing and protect the polyurethane foam filler. However, after long-term use, the position of the self-tapping screws is easily eroded, and rainwater will also leak into the room from the position of the self-tapping screws, which cannot achieve a long-term waterproofing effect.

[0027] Example

[0028] like Figure 1 As shown, this embodiment discloses an easily adjustable roof leakage blocking structure, which is used to block the expansion joint 7 between two roof panels 1 to prevent rainwater from leaking into the room through the expansion joint 7.

[0029] The easily adjustable roof leakage plugging structure comprises two fixing members 5 and a cover plate 4. The two fixing members 5 are respectively fixed to the upper ends of the purlins 3 under the two roof panels 1, and the lower ends of the purlins 3 are fixed to the steel beams 2; the two ends of the cover plate 4 are respectively connected to the two fixing members 5.

[0030] Specifically, Figure 2 , 3 As shown, the fixing member 5 includes a panel 55; one end of the panel 55 away from the expansion joint 7 is bent downward by 180 degrees to form a fixing member bending section 51, and the other end is also bent downward to form a fixing section 53. A fixing member slot 52 is formed between the fixing member bending section 51 and the panel 55, and the fixing section 53 is connected to the purlin 3 through a self-tapping screw 6.

[0031] Correspondingly, the edge of the roof panel 1 is bent upward by 180° to form a roof panel bending section 11, and a roof panel slot 12 is formed between the roof panel bending section 11 and the roof panel 1. The roof panel bending section 11 is inserted into the fixing member slot 52, and the fixing member bending section 51 is inserted into the roof panel slot 12. In this way, the roof panel 1 and the fixing member 5 are connected together. The lower surface of the end of the roof panel 1 is also supported on the purlin 3, which can improve the installation strength of the roof panel 1.

[0032] In addition, there is a clearance fit between the roof panel bending section 11 and the fixing member slot 52, as well as between the fixing member bending section 51 and the roof panel slot 12, and there is movable space between the roof panel bending section 11 and the end of the fixing member slot 52, as well as between the fixing member bending section 51 and the end of the roof panel slot 12, so that the roof panel 1 can move relative to the fixing member 5, thereby meeting the activity requirements of the roof panel 1 due to thermal expansion and contraction.

[0033] In addition, if Figure 2 , 4 As shown, both ends of the cover plate 4 are bent downward to form a cover plate bending section 41, and a cover plate slot 42 is formed between the cover plate bending section 41 and the cover plate 4. The ends of the two fixing members 5 away from the expansion joint 7 are respectively inserted into the cover plate slots 42 at both ends of the cover plate 4. Figure 2 Similarly, the end of the fixing member 5 and the cover plate slot 42 may also be clearance-fitted.

[0034] Through the above structure, the fixing member 5, the cover plate 4 and the roof panel 1 are bent and matched with each other, so that rainwater cannot enter the expansion joint 7 from the edge of the roof panel 1, which plays a good waterproof role, and there is a certain adjustment margin between the three, so the demand for thermal expansion and contraction of the roof panel 1 can be met. In addition, through the above structure, the self-tapping screw 6 is covered under the cover plate 4, such as Figure 2 As shown, rainwater cannot penetrate into the room from the self-tapping screws, further improving the waterproof performance.

[0035] In addition, if Figure 1 As shown, the side of the roof panel 1 close to the expansion joint 7 is inclined upward, so that rainwater can flow downward along the roof panel 1, achieving a better waterproof effect.

[0036] like Figure 3 As shown, a reinforcing portion 54 is provided between the panel 55 and the fixing section 53 to enhance the strength of the entire fixing member 5 .

[0037] like Figure 4 As shown, both sides of the cover plate 4 are inclined downward to form a drainage slope, and a reinforcing rib 43 is provided in the middle of the cover plate 4 to improve the strength of the cover plate 4.

[0038] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0039] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
