[0002] The steel structure roof is a roof made of colored steel tiles. Its characteristics are light weight, high material strength and easy implementation.

[0003] The steel structure roofs currently used have almost no waterproof or anti-seepage structures and have poor waterproof properties. In particular, rainwater can easily penetrate into the joints between two colored steel tiles, causing corrosion to the interior of the roof structure and even dripping into the house, causing damage to items.

[0004] Therefore, we designed a steel structure roof joint anti-seepage structure. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a steel structure roof joint anti-seepage structure.

[0010] A connecting assembly is used to clamp the top surfaces of the two color steel tiles and the bottom surfaces of the two first bending parts so that the two butted color steel tiles are connected to the joint drainage groove;

[0011] Wherein, the width of the second bending portion is greater than the width of the folded edge.

[0012] Preferably, the connection assembly comprises:

[0013] A T-bolt is inverted, and the head of the T-bolt contacts the bottom surfaces of the two first bending portions;

[0014] The locking nut is threaded onto the T-bolt screw rod, and the locking nut is crimped onto the top surfaces of the two spliced ​​color steel tiles.

[0015] Preferably, the T-bolt screw rod is provided with a crimping piece corresponding to the position below the locking nut.

[0018] Preferably, the bottom surface of the third bent portion abuts against the top surface of the corresponding raised portion.

[0019] Preferably, the bending angle between the second bending portion and the third bending portion is an arc angle.

[0024] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0025] Embodiment 1, in combination with the attached Figure 1-2 , a steel structure roof joint anti-seepage structure, comprising:

[0026] The color steel tile 1 has downward folded edges 11 on both sides;

[0027] The joint drainage groove 2 is arranged below the joint of the two color steel tiles 1; the joint drainage groove 2 has an arc-shaped drainage portion 21, both sides of the arc-shaped drainage portion 21 are provided with an inward first bending portion 22, the inner side of the first bending portion 22 is provided with an upward second bending portion 23, and the upper side of the second bending portion 23 is provided with an outward third bending portion 24;

[0028] During the specific operation, the inner side of the second bending portion 23 contacts the outer side of the corresponding folding edge 11; it should be noted that: the inner and outer directions are as shown in the attached Figure 2 shown.

[0029] The connecting assembly 3 is used to clamp the top surfaces of the two color steel tiles 1 and the bottom surfaces of the two first bending parts 22 to facilitate the connection of the two butted color steel tiles 1 with the joint drainage groove 2;

[0030] Furthermore, the connection component 3 includes:

[0031] The T-bolt 31 is inverted, and the head of the T-bolt 31 abuts against the bottom surfaces of the two first bending portions 22;

[0032] The locking nut 32 is screwed to the screw rod of the T-bolt 31 , and the locking nut 32 is pressed to the top surfaces of the two spliced ​​color steel tiles 1 .

[0033] It should be noted that the head of the T-bolt 31 and the locking nut 32 cooperate to clamp the top surfaces of the two spliced ​​color steel tiles 1 and the bottom surfaces of the two first bent portions 22; at this time, the top surface of the third bent portion 24 is tightly in contact with the bottom surface of the corresponding color steel tile 1, thereby realizing the function of connecting the two docked color steel tiles 1 with the joint drainage groove 2.

[0034] Among them, the width of the second bending portion 23 is greater than the width of the folded edge 11; in this way, it can be ensured that after the top surface of the third bending portion 24 is tightly in contact with the bottom surface of the corresponding color steel tile 1, the head of the T-bolt 31 can still contact the bottom surfaces of the two first bending portions 22, ensuring that there is a large contact force between the top surface of the third bending portion 24 and the bottom surface of the corresponding color steel tile 1.

[0035] There is an arc-shaped drainage portion 21 under the joint formed by the two color steel tiles 1 spliced ​​in this way. At this time, rainwater passing through the joint can be guided and discharged by the arc-shaped drainage portion 21, which solves the technical problem of water seepage inside the roof structure at the joint in the prior art.

[0036] Embodiment 2, combined with the attached Figure 1-2 , a steel structure roof joint anti-seepage structure, based on the first embodiment, in order to prevent the locking nut 32 from sliding and rubbing against the top surface of the color steel tile 1, resulting in damage to the paint layer on the surface of the color steel tile 1, a T-bolt 31 screw rod is provided with a matching sleeve with a crimping piece 33 corresponding to the position below the locking nut 32. The crimping piece 33 can be made of a flexible material, such as rubber, etc. as needed.

[0037] Furthermore, to prevent a large deviation in the positional relationship between the joint drainage groove 2 and the two color steel tiles 1, a downwardly extending limit sleeve 331 is provided in the middle of the bottom surface of the crimping piece 33; thus, the distance between the folded edges 11 of the two color steel tiles 1 can be controlled by the limit sleeve 331.

[0038] In this embodiment, the outer section of the first bending portion 22 has an upward protrusion 221, and both ends of the head of the T-bolt 31 are provided with a protrusion 311 embedded in the corresponding protrusion 221; in this way, the position of the T-bolt 31 can be limited by the embedded cooperation of the protrusion 311 and the protrusion 221, and the limiting sleeve 331 can effectively make the two folded edges 11 symmetrical relative to the middle of the joint drainage groove 2, thereby preventing a large deviation in the positional relationship between the joint drainage groove 2 and the two color steel tiles 1, and can ensure the strength of the cooperation between the multiple bending portions on the side of the arc-shaped drainage portion 21 and the side of the color steel tile 1.

[0039] Furthermore, the bottom surface of the third bending portion 24 abuts against the top surface of the corresponding protrusion 221; in this way, the third bending portion 24 can be supported by the protrusion 221 to prevent the protrusion 221 from being excessively bent, that is, the third bending portion 24 can be ensured to be in surface contact with the corresponding color steel tile 1.

[0040] Furthermore, the bending angle between the second bending portion 23 and the third bending portion 24 is an arc angle.

[0041] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
