Description

Technical Field

[0001] The utility model relates to the technical field of color steel panels, in particular to a keel fastener for a construction enclosure of a color steel panel. Background Art

[0002] Color steel panel enclosure is a temporary enclosure commonly used in existing municipal construction projects. According to the color steel panel and keel guardrail described in patent application number CN201920693198.4 "A color steel panel and guardrail", it includes a color steel panel and a keel guardrail, the connecting ends of the two color steel panels are bent, and an L-shaped slot is provided on the keel guardrail. A triangular protrusion is provided on the inner side of the L-shaped slot. The connecting end of the color steel panel is placed on the inner side of the slot, and the triangular protrusion is used to support the connecting end of the color steel panel to fix the color steel panel. The structure of the keel guardrail and the color steel panel is clamped together, and the overall structure is simple and easy to operate. However, in actual use, the connecting end of the color steel panel is easy to detach from the L-shaped slot on windy days, and the fixing effect of the triangular protrusion is not ideal. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a keel fastener for a construction enclosure of a color steel panel in view of the above shortcomings.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A color steel panel construction enclosure keel fastener comprises a channel steel, wherein an L-shaped slot is provided at the opening of the channel steel for the color steel panel connection end to be inserted into, wherein the L-shaped slot comprises a vertical section and a horizontal section, wherein a rectangular protrusion is provided at the lower corner where the horizontal section is connected to the vertical section, and the rectangular protrusion is inclined inwardly on the side close to the horizontal section.

[0006] Furthermore, a circular protrusion is provided at the top corner of the rectangular protrusion, and the circular protrusion protrudes from the side of the rectangular protrusion close to the vertical section.

[0007] Furthermore, an arc-shaped depression is provided on one side of the rectangular protrusion close to the horizontal section, and after the connecting end of the color steel panel enters the L-shaped slot, the end of the connecting end of the color steel panel abuts against the arc-shaped depression.

[0008] Furthermore, the upper corner where the horizontal section and the vertical section are connected is rounded.

[0009] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0010] The utility model can well fix the color steel panel connection end by arranging a rectangular convex piece on the inner side of the horizontal section of the L-shaped slot, and arranging the side of the rectangular convex piece close to the horizontal section to have an inclined edge, or adding a circular convex piece at the top corner of the rectangular convex piece. The rectangular convex piece provides a basic blocking effect, and the circular convex piece further prevents the color steel panel from loosening or falling off under the action of strong winds or other external forces through its protruding design and close cooperation with the color steel panel connection end, thereby improving the stability and safety of the overall enclosure. The connection between the horizontal section and the vertical section is rounded, so that the color steel panel connection end can smoothly enter the horizontal section through the cavity between the inner wall of the vertical section and the circular convex piece, and abut against the arc-shaped depression of the rectangular convex piece so that the color steel panel connection end can be restricted to the inner side of the horizontal section.
