[0002] With the development of the construction industry and steel materials, steel structure buildings are increasing day by day. Therefore, the advantages of steel structure can be better utilized in high-rise buildings, large factories, large-span space structures, transportation and energy projects, and residential buildings. And with the increasing number of steel structure workshops, the leakage phenomenon of steel structure workshops that have been built and put into use is also increasing, which hinders the normal use of steel structure workshops.

[0003] The corners of the steel structure workshop corresponding to the wall panels need to be edged. The existing method is to edge the flashing board, which is fixed by self-tapping screws. When installing the flashing board, it is necessary to manually straighten the flashing board and then install the screws, which is a cumbersome process. The utility model mainly provides a flashing board installation structure that can be pre-fixed to avoid the problem of installation error caused by misalignment of the handrail.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-2 As shown: a steel structure factory wall corner anti-leakage structure, including a steel structure 3 located inside a wall panel 2, an I-beam 4 at the wall corner position of the steel structure 3, a wall panel 2 at the outside of the steel structure 3, and a flashing board 1 at the wall corner position of the wall panel 2;

[0021] The flashing board 1 is strip-shaped and has an edge from top to bottom along the wall corner. The flashing board 1 has two extension parts 11 on both sides. The two extension parts 11 on both sides are bent approximately 90 degrees corresponding to the midline position to form a bending part. The bending part corresponds to the wall corner. The extension part 11 is used to stick to the corresponding wall panels 2 on both sides.

[0022] Embodiment 1: The bending portion bulges outward to form an elastic portion 12. The elastic portion 12 is strip-shaped and extends along the bending portion. The cross-section of the elastic portion 12 is a U-shaped structure. The extension portion and the elastic portion are an integrated structure, which is formed by bending a 4mm galvanized steel plate through a bending machine. The elastic portion is a U-shaped structure, which is used to retract the extension portions on both sides. During installation, the corresponding corner position is 90°. The extension portions on both sides are attached to the corresponding wall panels. The bending portion formed between the extension portions is less than 90°. It is necessary to manually overcome the resistance of the elastic portion to pry it apart, and then buckle it at the corner position. The arc position formed by the elastic portion can elastically press the extension portions on both sides, so that the inner side of the extension portion is tightly attached to the wall panel without the need for hand support. Finally, the corresponding extension portion is reinforced by self-tapping bolts. The installation convenience of the flashing board is improved, and the installation deviation problem caused by the misalignment of the hand support is prevented.

[0023] like Figure 2 As shown, the extension part 11 has a first plane part 13 and a second plane part 14, and the first plane part 13 and the second plane part 14 are connected by an inclined part 15; the second plane part 14 has a strip groove 16 for installing a sealing strip. Since the wallboard has a reinforcing edge to increase the strength, the corresponding extension part is bent at the position of the corresponding reinforcing edge in order to better fit the wallboard to prevent rainwater from entering.

[0024] The elastic part 12 has arc-shaped transitions corresponding to the extension parts on both sides, thereby increasing the deformation space and preventing deformation.

[0025] Embodiment 2: Figure 3 As shown, the cross section of the elastic part 12 is an arc-shaped structure, which helps to increase the elastic extension space of the elastic part and improve the pressing strength.

[0026] Embodiment 3: Figure 4As shown, the bending portion bulges inward to form an elastic portion 12, and the cross-section of the elastic portion 12 is a V-shaped groove structure, corresponding to the arc transition at the bottom of the groove, and a plurality of pressing pieces 5 are installed in the groove corresponding to the elastic portion 12. Another structure of the elastic portion is provided, which is curved inward to reduce the extra part formed outward, and has the same elastic contraction effect, saving external space. The projection shape of the pressing piece 5 is V-shaped, and a cross plate 51 is connected between the inner side walls corresponding to the pressing piece 5. Holes are provided at the bottom of the cross plate 51 and the pressing piece 5, and are fixed to the elastic portion 12 by self-tapping screws 52. The pressing piece is pressed against the groove by rotating the self-tapping screws, and the side wall corresponding to the pressing piece contacts the groove corresponding to the elastic portion, forcing the groove to open. The extension portion connected to the elastic portion compresses the wall panel when the groove expands, thereby increasing the pressing strength of the extension portion.

[0027] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
