[0002] In the current engineering construction field, the angle of the outer edge of the exterior wall is required to be a 90-degree right angle. Square edges and clear edges are the general requirements of construction. However, the requirements for the arc shape of the exterior wall are extremely rare, so there is a lack of relevant construction methods. In addition, during the construction of exterior wall insulation, the common panels on the market cannot meet the requirements for the shape of the arc surface, and the shape of the base material restricts the quality of the final molding surface. Utility Model Content

[0003] The utility model aims to provide a customized plate assembly structure for the arc angle position of the external wall, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides a customized plate assembly structure at the arc corner position of the external wall corner, including: an arc corner extruded plate and an external wall insulation nail assembly, wherein a plurality of arc corner extruded plates are staggered and overlapped in sequence along the vertical direction at the arc corner position of the external wall corner, and a plurality of reserved holes are opened on the arc corner extruded plate for setting the external wall insulation nail assembly; wherein the arc corner extruded plate includes a long plate surface and a short plate surface connected in an integral manner, the area of ​​the short plate surface is larger than the area of ​​the long plate surface, the inner sides of one end where the long plate surface and the short plate surface are connected to each other are spliced ​​together to form a right angle, and the outer sides of one end where the long plate surface and the short plate surface are connected to each other are spliced ​​together to form an arc corner; the external wall insulation nail assembly includes an adjustable nail barrel and a steel insulation nail, one end of the adjustable nail barrel is arranged in the external wall body, and the other end is arranged in the reserved hole of the arc corner extruded plate, and the steel insulation nail is inserted in the adjustable nail barrel.

[0005] In a preferred embodiment, the adjustable nail barrel is a hollow cylindrical structure, in which a plurality of adjustable scale grooves are arranged at intervals in the middle, and an adjustable limit ring is arranged on the adjustable nail barrel. The adjustable limit ring is clamped in one of the adjustable scale grooves and can be moved and adjusted within the adjustable scale range, and the outer side surface of the adjustable limit ring fits the arc angle extruded plate.

[0006] In a preferred embodiment, the spacing between two adjacent adjustable scale grooves is 2 mm, the thickness of the adjustable limit ring is consistent with the thickness of the adjustable scale groove, the inner diameter of the adjustable limit ring is larger than the size of the adjustable scale groove, the inner diameter of the adjustable nail tube is larger than the outer diameter of the steel insulation nail, and the inner end of the steel insulation nail is provided with a pointed head and the outer end is provided with a plastic enlarged top cap.

[0007] In a preferred embodiment, the sizes of two arc-angle extruded plates adjacent to each other in the vertical direction are exactly the same, wherein the lower arc-angle extruded plate is flipped 180° with the upper arc-angle extruded plate, and the short plate surface of the lower arc-angle extruded plate is located below the long plate surface of the upper arc-angle extruded plate, and the long plate surface of the lower arc-angle extruded plate is located below the short plate surface of the upper arc-angle extruded plate.

[0008] In a preferred embodiment, the area of ​​the short board surface is 1 / 2 of the area of ​​the long board surface.

[0009] In a preferred embodiment, four reserved holes are symmetrically arranged in a square shape on the short board surface, and five reserved holes are evenly arranged on the long board surface, four of which are symmetrically arranged in a rectangular shape, and the other reserved hole is arranged at the midpoint of the diagonal of the rectangle.

[0010] In a preferred embodiment, after the arc-corner extruded panels are assembled, a first layer of mesh cloth is fixedly disposed on the joints between two adjacent arc-corner extruded panels and on the arc-corner extruded panels.

[0011] Compared with the prior art, the beneficial effect of the utility model is that during the external wall insulation construction process, the common panels on the market cannot meet the requirements of the arc surface shape, and the shape of the base material restricts the quality of the final molding surface. Therefore, during the construction of the outer corner of the insulation exterior wall, the utility model adopts a customized arc angle extruded board, so that the arc base can be guaranteed during the base construction process. Since the corner position is subject to the greatest structural stress, the displacement is large and cracks are prone to occur. The assembly structure of the utility model not only solves the problem of weak nodes in the connection of the panels, but also sets the arc angle of the panels, which provides a reasonable basic structure for the subsequent plastering construction, which is conducive to subsequent construction. The utility model has higher fixing strength and is more firmly installed. The hard plastic nail barrel with a certain strength can also provide a certain support force, which is more secure than the combination of bonding mortar + insulation nails involved in conventional construction methods. At the same time, because the adjustable nail barrel is constructed first, it can provide an additional support force when bonding the panels, effectively controlling the slippage of the panels. By using the scale adjustment method, the flatness of the wall and the corners can be more accurately controlled with a scale spacing of 2mm. By innovating the fixing tool method, the installation accuracy of the exterior wall insulation board can be controlled within 2mm. With the help of the limit ring, the operator can clearly customize the bonding gap between the board and the wall in advance, so as to make corresponding countermeasures.
