AI Technical Summary

Technical Problem

In the metal enclosure system, the setting of the cornice nodes is unreasonable, causing rainwater to contact the substrate, causing corrosion of the substrate, and lack of effective waterproofing measures.

Method used

A cornice node structure is designed, including the cornice angle steel arranged on the top surface of the roof eaves and the inner side of the wall outer panel, the metal strips arranged between the bottom surface of the roof panel and the top surface of the angle steel, and the cornices arranged on the lower end of the metal strips and the outer side of the cornice angle steel. The metal strips and cornices are poured through the inclined connection section to form an inclined downward drainage channel to ensure that the water droplets are discharged along the vertical section.

Benefits of technology

Through the designed eaves node structure, rainwater falls from the roof panel and is discharged along the vertical section of the eaves, effectively preventing water droplets from touching the substrate and significantly improving the waterproofing effect.

If the eave node is not reasonably arranged, the rainwater flowing down from the roof panel will contact the base material (such as a wooden strip, etc.) at the eave node of the roof, causing corrosion of the base material. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an eave node structure with good waterproof effect.

[0004] The technical solution of this application is: An eave node structure is arranged between the roof panel and the external wall panel, and includes an eave angle steel arranged between the top surface of the roof purlin and the inner side surface of the external wall panel, a metal pressing strip arranged between the bottom surface of the roof panel and the top surface of the angle steel, and an eave flashing arranged at the lower end of the metal pressing strip and the outer side surface of the eave angle steel. The metal pressing strip is parallel to the roof panel as a whole. Its head end is in a right-angled shape, and its tail end is in a horizontal shape. The horizontal section at the head end is connected to the roof panel by self-tapping screws. Between the head end and the tail end of the metal pressing strip is a connecting section arranged obliquely downward, so that there is a certain gap left between the tail end of the metal pressing strip and the bottom surface of the roof panel. The tail end of the eave flashing is in a right-angled shape. The horizontal section is attached between the bottom surface of the tail end of the metal pressing strip and the top surface of the roof purlin, and the vertical section is attached to the eave angle steel. The head end of the eave flashing is a vertical section parallel to the outer side surface of the external wall panel. Between the head end and the tail end of the eave flashing is a connecting section inclined upward. The vertical section at the head end of the metal pressing strip is located outside the vertical section at the head end of the eave flashing. The self-tapping screws connecting the horizontal section at the head end of the metal pressing strip and the roof panel are arranged between the vertical section at the head end of the metal pressing strip and the vertical section at the head end of the eave flashing.

[0005] Wherein, an eave trim in a multi-segment broken line shape is further arranged at the bottom of the roof panel. The upper end of the eave trim is located outside the head end of the metal pressing strip, and its lower end is fixed on the external wall panel.

[0006] The horizontal section and the vertical section of the eave angle steel are respectively fixed to the roof purlin and the inner side surface of the roof external panel by flat head self-tapping screws.

[0007] The horizontal section at the tail end of the eave flashing and the horizontal section at the tail end of the metal pressing strip are fixed by rivets.

[0008] The free end of the horizontal section of the metal pressing strip, the horizontal section of the eave angle steel and the roof purlin are integrally connected by self-tapping screws.

[0009] The advantages and beneficial effects of this application are: The water flowing down from the roof panel falls from the nail hole when passing through the nailing place and is discharged along the vertical section of the eave flashing, with good waterproof effect.

[0013] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0014] As Figure 1 shown, the technical solution proposed by the present utility model is:

[0015] An eave node structure is provided between the roof panel 2 and the outer wall panel 1, including an eave angle steel 4 provided between the top surface of the roof eave purlin 3 and the inner side surface of the outer wall panel 1, a metal pressing strip 5 provided between the bottom surface of the roof panel 2 and the top surface of the angle steel, and an eave flashing 6 provided at the lower end of the metal pressing strip 5 and the outer side surface of the eave angle steel 4. As Figure 2 shown, the metal pressing strip 5 is disposed parallel to the roof panel 2 as a whole. Its head end is in a right-angled shape, and its tail end is in a horizontal shape. The horizontal section at the head end is connected to the roof panel 2 by self-tapping screws. A connecting section is disposed obliquely downward between the head end and the tail end of the metal pressing strip 5, so that a certain gap is left between the tail end of the metal pressing strip 5 and the bottom surface of the roof panel 2, and heat insulation cotton can be added, so that the roof heat insulation and the wall heat insulation form a closed loop.

[0016] The tail end of the eave flashing 6 is in a right-angled shape. The horizontal section is attached between the bottom surface of the tail end of the metal pressing strip 5 and the top surface of the roof eave purlin 3, and the vertical section is attached to the eave angle steel 4. The head end of the eave flashing 6 is a vertical section parallel to the outer side surface of the outer wall panel 1. A connecting section is disposed obliquely downward between the tail end and the head end of the eave flashing 6, that is, it is bent obliquely downward as a whole for drainage.

[0017] The vertical section at the head end of the metal pressing strip 5 is located outside the vertical section at the head end of the eave flashing 6. The self-tapping screws connecting the horizontal section at the head end of the metal pressing strip 5 and the roof panel 2 are disposed between the vertical section at the head end of the metal pressing strip 5 and the vertical section at the head end of the eave flashing 6. The water flowing down from the roof panel 2 falls from the nail hole when passing through the nailing position and drains down along the vertical section of the eave flashing 6.

[0018] Wherein, an eave trim 7 in a multi-segment broken line shape is further provided at the bottom of the roof panel 2. The upper end of the eave trim 7 is located outside the head end of the metal pressing strip 5, and its lower end is fixed to the outer wall panel 1.

[0019] Among them, the metal batten 5, the eave flashing 6 and the eave trim 7 can all be made of hard metal materials.

[0020] The horizontal section and the vertical section of the eave angle steel 4 are respectively fixed to the roof eave purlin 3 and the inner side surface of the roof outer panel by flat head self-tapping screws 8.

[0021] The end horizontal section of the eave flashing 6 and the end horizontal section of the metal batten 5 are fixed by rivets 10.

[0022] The free end of the horizontal section of the metal batten 5, the horizontal section of the eave angle steel 4 and the roof eave purlin 3 are integrally connected by self-tapping screws 9.
