Description

Technical Field

[0001] The utility model relates to the technical field of building plates, in particular to a hidden nail type prefabricated metal profiled plate. Background Art

[0002] Prefabricated metal corrugated panels for wall surfaces generally include a flat main structure and reinforcing ribs protruding from the main structure. The shape and lines of metal corrugated panels are suitable for large-scale buildings. In addition, they are quick to install and economical and practical, so they have been widely used. In traditional structural settings, exposed screws are required to fix adjacent metal corrugated panels at the ends. The metal corrugated panels expand and contract due to temperature changes, which can cause deformation of the nail holes and create a risk of water leakage. In addition, exposed screws are also prone to rust, which affects the service life of the wall.

[0003] In the related technical scheme, the inventor sets a hidden screw connection structure at the metal corrugated plate with corrugated ribs, and the hidden screw connection structure includes sub-ribs and mother ribs. The mother ribs are connected to the corrugated ribs at the end of the metal corrugated plate, and the corrugated ribs form hidden spaces for the sub-ribs and the mother ribs.

[0004] However, in other technical solutions, the metal corrugated plate is roughly flat (i.e., the height of the ribs on the surface of the metal corrugated plate is very low), and it is impossible to use the wavy high ribs at both ends of the metal corrugated plate to form sub-ribs and hidden space for screws, thereby making it difficult to form a hidden screw structure. Utility Model Content

[0005] The utility model provides a hidden nail type prefabricated metal profiled plate, which can at least solve one of the above technical problems.

[0006] To solve the above technical problems, one or more embodiments of the utility model provide a hidden nail prefabricated metal corrugated plate, including a plate body, a main rib and a sub-rib, wherein the plate body extends along a first direction and has a plurality of reinforcing ribs on the surface of the plate body.

[0007] The mother rib is connected to one end of the plate body along the first direction. The mother rib includes a first folded edge, a second folded edge and a third folded edge extending outward from the center of the plate body in sequence to form a trapezoidal structure. The trapezoidal structure protrudes from the plate body. The mother rib also includes a fourth folded edge extending laterally from the third folded edge toward the center of the plate body and a fifth folded edge inclined upward away from the center of the plate body; the transverse length of the fourth folded edge is equal to half of the distance between the bottom end of the third folded edge and the bottom end of the first folded edge; the sub-rib is L-shaped, protruding from the plate body, and the sub-rib and the plate body enclose a transverse slot toward the center of the plate body. The height of the slot is greater than the upper end height of the fifth folded edge, and a screw connecting to the external structure is provided on one side of the sub-rib.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] (1) In this solution, a first folded edge, a second folded edge, a third folded edge, a fourth folded edge and a fifth folded edge are additionally extended at one end of the main body and connected in sequence, wherein the first three folded edges are enclosed to form a trapezoidal structure, and the trapezoidal structure can form an inner cavity isolated from the outside after the corrugated board is attached to the wall purlin, and then the hook structure, sub-ribs and connecting screws formed by the fourth folded edge and the fifth folded edge are covered in the inner cavity, thereby facilitating the hiding of corresponding structures such as sub-ribs and screws when there are no high corrugated ribs at both ends of the corrugated board.

[0010] (2) The structure formed by the first fold, the second fold and the third fold in this solution is a trapezoid. Compared with the wavy ribs used to cover the sub-ribs and screws in the existing structure, the trapezoidal structure is convenient for realizing the symmetrical arrangement of the trapezoidal structure at the connection between the sub-rib and the mother rib by cooperating with the feature that the transverse length of the fourth fold is equal to half of the distance between the bottom end of the third fold and the bottom end of the first fold, so that the first fold and the third fold evenly bear the load.

[0026] Example 1

[0027] See also Figure 1-Figure 2An embodiment of the utility model provides a hidden nail prefabricated metal corrugated plate, comprising a plate body 1, a main rib 2 and a sub-rib 4. The plate body 1 extends along a first direction, and a surface of the plate body 1 has a plurality of reinforcing ribs 3.1. The mother rib 2 is connected to one end of the plate body 1 along the first direction. The mother rib 2 includes a first folded edge 2.5, a second folded edge 2.4 and a third folded edge 2.3 extending outward from the center of the plate body 1 in sequence and forming a trapezoidal structure. The trapezoidal structure is protruding from the plate body 1. The mother rib 2 also includes a fourth folded edge 2.2 extending laterally from the third folded edge 2.3 toward the center of the plate body 1 and a fifth folded edge 2.1 extending upward from the fourth folded edge 2.2 away from the center of the plate body 1. The length of the fourth folded edge 2.2 along the transverse direction is approximately equal to one-half of the distance between the bottom end of the third folded edge 2.3 and the bottom end of the first folded edge 2.5. The sub-rib 4 is L-shaped, protruding from the plate body 1, and the sub-rib 4 and the plate body 1 enclose a transverse notch 4.1 toward the center of the plate body 1. The height of the notch 4.1 is greater than the upper end height of the fifth folded edge 2.1. A screw 5 for connecting to an external structure is provided on one side of the sub-rib 4.

[0028] In this embodiment, the fourth folded edge 2.2 extends in the transverse direction, and the angle between the fourth folded edge 2.2 and the plane where the plate body 1 is located is approximately 0 degrees to 10 degrees.

[0029] Specifically, the first folded edge 2.5 and the third folded edge 2.3 are symmetrically arranged about the middle second folded edge 2.4, the second folded edge 2.4 is parallel to the plane where the plate body 1 is located, and the angle between the first folded edge 2.5 and the second folded edge 2.4 and the angle between the second folded edge 2.4 and the third folded edge 2.3 are the same.

[0030] Specifically, in this embodiment, the height of the reinforcing rib 3.1 is 4 mm, and the height of the notch 4.1 at the sub-rib 4 is 10 mm.

[0031] In this embodiment, the sub-rib 4, the main rib 2 and the plate body 1 are an integrally formed structure, wherein the end of the body away from the main rib 2 is formed into the sub-rib 4 by a double-layer rolling and bending structure, and thus the sub-rib 4 is a double-layer structure.

[0032] Specifically, the plate body 1 forms a straight section 3 at the portion where no reinforcing ribs 3.1 are provided, and the straight section 3 is a planar plate-like structure.

[0033] In this embodiment, the reinforcing rib 3.1 is trapezoidal, and the width of the upper end of the reinforcing rib 3.1 is smaller than the width of the lower end of the reinforcing rib 3.1.

[0034] In this embodiment, the reinforcing rib 3.1 closest to the sub-rib 4 is the abutting rib 3.10, and the sub-rib 4 has a stop section which is away from the center of the plate body 1 and is vertically arranged, and the distance between the stop section and the abutting rib 3.10 is equal to the length of the fourth folded edge 2.2 in the horizontal direction. Figure 2After the two adjacent metal profiled plates are buckled by the sub-rib 4 and the parent rib 2, the third folded edge 2.3 and the fourth folded edge 2.2 of the latter metal profiled plate stop at the side of the abutting rib 3.10, and then the abutting rib 3.10 can limit the movement of the parent rib 2 shown in the figure in the direction of separation from the sub-rib 4. That is, the structure of the abutting rib 3.10 cooperates with the mutual buckling of the sub-rib 4 and the parent rib 2 to limit the sliding of the adjacent metal profiled plates along the plane direction. In addition, the abutting rib 3.10 plays the role of shielding the overlapping gap between the parent rib 2 and the sub-rib 4, which can further prevent external rainwater from flowing into the position where the screw 5 is located.

[0035] In this embodiment, the sub-rib 4 has a transverse extension section 4.2 on one side away from the center of the plate body 1, and the extension section 4.2 has a second connection hole. In this embodiment, the reinforcing rib 3.1 has the same length as the straight section 3 along the first direction. In coordination with this, a screw 5 for connecting to a wall purlin 6 or other structures is inserted into the second connection hole of the extension section 4.2.

[0036] In addition, an upwardly inclined flange 4.3 is provided at one end of the extension section 4.2 away from the sub-rib 4, and the included angle between the flange 4.3 and the extension section 4.2 is an obtuse angle.

[0037] During use, when installing, first tighten the extension section 4.2 at the position of the previous metal corrugated sheet rib 4 to the wall purlin 6 through screws 5, and then insert the hook composed of the fourth folded edge 2.2 and the fifth folded edge 2.1 of the next metal corrugated sheet mother rib 2 into the "L"-shaped groove 4.1 of the previous metal corrugated sheet mother rib 2 to complete the connection between the plate bodies 1.

In this embodiment, the first reinforcing rib 3.12 and the second reinforcing rib 3.11 are arranged alternately.

[0043] Specifically, the height of the first reinforcing rib 3.12 is 25 mm, which is the same as the height of the mother rib 2, and the height of the second reinforcing rib 3.11 is 4 mm.

[0044] Specifically, the first reinforcing rib 3.12 includes two oblique edges 3.121 and one straight edge 3.122, and the angle between the two oblique edges 3.121 and the straight edge 3.122 is an obtuse angle.

[0045] Example 4

[0046] See also Figure 7-10 The structural arrangement of this embodiment is basically the same as that of the embodiment 1, except that, in this embodiment, the sub-rib 4 includes a sixth folded edge 4.7 and a seventh folded edge 4.6 which are bent in sequence from the end of the body, the sixth folded edge 4.7 is perpendicular to the plate body 1, and the seventh folded edge 4.6 is parallel to the plate body 1. That is, in this solution, no extension section is provided on the side of the sub-rib 4 away from the mother rib 2.

[0047] At this time, the seventh folded edge is parallel to the plate body and extends toward the mother rib;

[0048] In order to fix the metal corrugated plate on the wall purlin 6, the present embodiment also includes a separately arranged splicing buckle 7, which includes a connecting portion 71 and a buckling portion 72.
