[0002] At present, most steel structure factories are built with brick walls and color steel walls, and steel structure purlins are set between the two to provide transition connections, and flashing structures are set on the steel structure purlins.

[0003] For example, the applicant's prior application's authorization publication number is CN 217652054 U's Chinese patent discloses a flashing and trimming structure for a steel structure industrial plant, comprising a brick wall, a steel structure wall arranged above the brick wall, a steel structure purlin arranged between the brick wall and the steel structure wall to form a transition connection, and a flashing and trimming assembly, wherein the steel structure purlin protrudes outward relative to the brick wall and the steel structure wall, and the flashing and trimming assembly comprises a support member and a trimming member: the support member comprises a horizontal support plate, a longitudinal support plate and an oblique liquid guide plate in sequence, the horizontal support plate is fitted with the upper surface of the steel structure purlin, the longitudinal support plate extends downward along the outer side surface of the steel structure purlin, the oblique liquid guide plate is obliquely arranged and inclined toward the direction of the brick wall, and the lower end of the oblique liquid guide plate is located below the lower surface of the steel structure purlin: the trimming member comprises a mounting portion fixedly connected to the steel structure wall, a first mating portion fitted with the horizontal support plate, a second mating portion fitted with the longitudinal support plate and a third mating portion fitted with the oblique liquid guide plate in sequence.

[0004] The applicant found that the following problems still exist:

[0006] Second, the trimmings that serve to block rain are attached to the outer side of the steel structure wall, that is, the water-blocking components are exposed to the outside. Therefore, the parts where the water-blocking components are in contact with the outer side of the steel structure wall are extremely susceptible to external erosion and weathering. After long-term use, there is a risk that rainwater will flow in through the gap between the steel structure wall and the trimmings. Utility Model Content

[0007] In response to the shortcomings of the existing technology, the present application provides a steel structure industrial plant flashing structure. By changing the structure of the steel structure purlins and the steel structure walls, the steel structure purlins and the steel structure walls cooperate to complete water retaining. The entire structure has fewer types and quantities of parts and is easier to install. At the same time, since the upper water retaining part with the water retaining function is hidden in the slot, the part where the upper water retaining part is in sealed contact with the outer side of the steel structure wall is not easily affected by external erosion and weathering, the sealing performance can be effectively maintained for a long time, and the water retaining effect is better.

[0008] A flashing structure of a steel structure industrial plant comprises a brick wall, a steel structure wall arranged above the brick wall, and steel structure purlins arranged between the brick wall and the steel structure wall to form a transition connection, wherein the steel structure purlin comprises a purlin main body and an upper water retaining part protrudingly arranged on the upper surface of the purlin main body; the steel structure wall comprises a wall main body and a retaining part arranged on the outer side of the wall main body, the retaining part comprises a transverse part and a vertical part located below the transverse part and connected to the transverse part, a slot is formed among the transverse part, the vertical part and the wall main body, and the upper water retaining part is inserted into the slot and is in sealing contact with the slot.

[0009] Preferably, the upper surface of the purlin main body is inclined downward from the upper water retaining portion to the outer side surface of the purlin main body to form a water guide surface 1.

[0010] Preferably, the inclination angle of the first water guide surface is 0-10°.

[0011] Preferably, the top surface of the transverse portion is inclined downward as it moves away from the wall main body portion and forms a second water guide surface.

[0012] Preferably, the vertical portion has a guide bottom surface for guiding the upwelling rainwater below the vertical portion outward.

[0013] Preferably, a flexible sealing layer 1 is provided on the surface of the upper water retaining portion.

[0014] Preferably, a second flexible sealing layer is provided on the surface of the slot.

[0015] Preferably, a lower water retaining portion is provided on the lower surface of the purlin main body, for laterally blocking the gap between the brick wall and the steel structure purlin.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1: The utility model changes the structure of the steel structure purlin and the steel structure wall so that the steel structure purlin and the steel structure wall cooperate to complete water retaining. The whole structure has fewer types and quantities of parts and is easier to install. At the same time, since the upper water retaining part with the water retaining function is hidden in the slot, the part where the upper water retaining part is in sealed contact with the outer side surface of the steel structure wall is not easily affected by external erosion and weathering, the sealing performance can be effectively maintained for a long time, and the water retaining effect is better.

[0019] 2: The utility model provides a flexible sealing layer on the surface of the upper water retaining part, so that the rigid impact of the steel structure purlin on the upper water retaining part during transportation or installation can be reduced, thereby protecting the upper water retaining part, which is relatively easy to be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 This is a schematic diagram of the flashing structure of a steel structure industrial plant;

[0021] Figure 2 for Figure 1 Structural schematic diagram of the steel structure wall;

[0022] Figure 3 for Figure 1 Schematic diagram of the structure of the steel structure purlin. DETAILED DESCRIPTION

[0023] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0024] Example: A steel structure industrial plant flooding structure, such as Figure 1-3 As shown, it includes a brick wall 1, a steel structure wall 2 arranged above the brick wall 1, and a steel structure purlin 3 arranged between the brick wall 1 and the steel structure wall 2 to form a transition connection.

[0025] The steel structure purlin 3 structurally comprises a purlin main body 31 and an upper water retaining portion 32 protrudingly provided on the upper surface of the purlin main body 31. The length of the upper water retaining portion 32 corresponds to the length of the purlin main body 31, and the two are equal. At the same time, the steel structure wall 2 structurally comprises a wall main body 21 and a retaining portion 22 provided on the outer surface of the wall main body 21. The retaining portion 22 specifically comprises a transverse portion 221 and a vertical portion 222 located below the transverse portion 221 and connected to the transverse portion 221. A slot 23 is formed between the transverse portion 221, the vertical portion 222 and the wall main body 21. The upper water retaining portion 32 is inserted into the slot 23. The shape of the upper water retaining portion 32 matches the shape of the slot 23 and is in sealed contact with the slot 23.

[0026] This steel structure industrial plant flooding structure abandons the existing method of using plate-like water-retaining parts. Instead, it modifies the structure of the steel structure purlins 3 and the steel structure wall 2, so that the steel structure purlins 3 and the steel structure wall 2 cooperate to complete the water retaining. The entire structure has fewer types and numbers of parts, which is easier to install. At the same time, because the upper water retaining part 32 with the water retaining function is hidden in the slot 23, the area where the upper water retaining part 32 contacts the outer surface of the steel structure wall is not easily eroded or weathered by the outside world, the sealing performance can be effectively maintained for a long time, and the water retaining effect is better.

[0027] In order to achieve sealed contact between the upper water retaining part 32 and the slot 23, a flexible sealing layer 1 can be provided on the surface of the upper water retaining part 32. Moreover, since the upper water retaining part 32 is a part that is relatively easy to be bumped and bruised in the entire steel structure purlin 3, the presence of the flexible sealing layer 1 can reduce the rigid impact and protect the upper water retaining part 32 during the transportation or installation process of the steel structure purlin 3. A flexible sealing layer 2 can also be provided on the surface of the slot 23.

[0028] The upper surface of the purlin body 31 is inclined downward from the upper water retaining portion 32 to the outer side surface of the purlin body 31, forming a water guide surface 31-1. The existence of the water guide surface 31-1 prevents rainwater from remaining on the upper surface of the purlin body 31 and causing rust on the upper surface of the purlin body 31. The inclination angle of the water guide surface 31-1 is preferably 0-10°.

[0029] The top surface of the transverse portion 221 slopes downward as it moves away from the wall main body 21 and forms a second water guide surface 221 - 1 to prevent rainwater from remaining on the top surface of the transverse portion 221 and causing rust on the top surface of the transverse portion 221 .

[0030] The vertical portion 222 has a guiding bottom surface 222-1, which can be a sloped surface that tilts upward as it moves away from the inner side surface of the vertical portion 222. It can be a 1 / 4 arc surface that is concave upward. When the space below the vertical portion 222 is filled with too much rain, causing it to surge upward along the outer side surface of the upper water retaining portion 32, the guiding bottom surface 222-1 can change the direction of the rainwater, guiding part of the rainwater outward, and reducing the amount of rainwater that surges into the gap between the inner side surface of the vertical portion 222 and the upper water retaining portion 32, which is beneficial to preventing water seepage.

[0031] A lower water retaining portion 33 is provided on the lower surface of the purlin main body 31, which is used to laterally block the gap between the brick wall 1 and the steel structure purlin 3. The existence of the lower water retaining portion 33 effectively prevents rainwater from penetrating into the gap between the brick wall 1 and the steel structure purlin 3. At the same time, the lower water retaining portion 33 belongs to the structure of the steel structure purlin 3, and does not increase the type and quantity of parts.

[0032] A plurality of reinforcement portions 34 are provided between the lower water retaining portion 33 and the lower surface of the purlin main body portion 31 to reduce damage during transportation.

[0033] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
