AI Technical Summary
In the prior art, the sealing performance of the inner connecting side of the gutter in the roof and the concrete wall is insufficient, resulting in rainwater leakage, and the node design between the roof panel and the roof eaves purlin is unreasonable, resulting in corrosion caused by rainwater contacting the substrate.
A roof gutter node is designed, including one end disposed between the wall purlin and the inner side of the daughter wall inner panel, and the other end is disposed between the roof panel and the roof eaves purlin. The same shape of gutter suspenders and metal strips are used. The head end of the metal strip is a right-angle plate, the tail end is parallel to the bottom surface of the roof panel, and the connection section is an inclined downwardly set between the head end and the tail end, leaving a certain gap, and butyl tape is used at the connection to improve sealing.
Through this design, rainwater falls directly into the inner gutter when it falls from the roof panel, avoiding backwater, significantly improving the waterproofing effect, and through improved node design, rainwater is avoided to contact the substrate, preventing corrosion, while enhancing the firmness of the inner gutter and gutter suspension.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel structure buildings, and particularly relates to a node of an internal gutter on a roof. Background Art
[0002] For the internal gutter of a building with a steel structure main body, a concrete parapet wall, and a metal profiled steel sheet or sandwich color steel plate on the roof, the common structure is that one end outside of the internal gutter is directly fixed to the inner side of the concrete parapet wall through expansion bolts, and the other end is fixed between the roof panel and the roof eave purlin. The problem is that the sealing performance of the connection side between the internal gutter and the inner side of the concrete parapet wall cannot be guaranteed, rainwater will not flow into the gutter, resulting in leakage. The node design between the roof panel and the roof eave purlin is unreasonable, and the rainwater flowing down from the roof panel will contact the base material (such as wooden strips, 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 a node of an internal gutter on a roof, which has a reasonable design and good waterproof effect.
[0004] The technical solution of this application is: a node of an internal gutter on a roof, including an internal gutter with one end arranged between the wall purlin and the inner side of the parapet wall inner plate, and the other end arranged between the roof panel and the roof eave purlin, a gutter sling having the same shape as the internal gutter and arranged on the periphery of the internal gutter, and a metal pressing strip arranged between the bottom surface of the roof panel and the top surface of the roof eave purlin. The head end of the metal pressing strip is a right-angle plate, and the tail end is parallel to the bottom surface of the roof panel. The horizontal section at the head end is connected to the roof panel through 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 a certain gap is left between the tail end of the metal pressing strip and the bottom surface of the roof panel.
[0005] Among them, one end of the gutter sling close to the wall purlin is fixed to the wall purlin through self-tapping screws. The end of the internal gutter connected to the inner side of the parapet wall inner plate is L-shaped. The vertical section of the L-shaped end of the internal gutter and the gutter sling are both fixed between the parapet wall inner plate and the wall purlin through the same self-tapping screw.
[0006] Among them, one end of the internal gutter close to the roof eave purlin is horizontal. One end of the gutter sling close to the roof eave purlin is a horizontal section. The horizontal section of the gutter sling is fixed to the horizontal top surface of the roof eave purlin through self-tapping screws. The horizontal end of the internal gutter close to the roof eave purlin and the horizontal section of the gutter sling are fixed to the roof eave purlin through the same self-tapping screw.
[0007] Furthermore, butyl tapes are padded between the horizontal section at the head end of the metal pressing strip and the roof panel, and between the horizontal section at the tail end of the metal pressing strip and the horizontal section of the gutter sling.
[0008] The advantages and beneficial effects of this application are as follows: The water flowing down from the roof panel drops from the nail holes when passing through the nailing points and directly falls into the inner gutter, avoiding water backflow and having a good waterproof effect.
[0009] One end of the inner gutter is arranged between the wall purlin and the inner side of the parapet wall inner panel. The end of the inner gutter connected to the inner side of the parapet wall inner panel is L-shaped. The vertical section of the L-shaped end of the inner gutter and the gutter sling are both fixed between the parapet wall inner panel and the wall purlin through the same self-tapping screw, eliminating the leakage problem caused by sealing problems in the prior art and ensuring the firmness of the inner gutter and the gutter sling at the same time. Description of the Drawings

[0013] The following will make a detailed description of the specific embodiment of the present utility model with reference to the drawings.
[0014] As Figure 1 shown, the technical solution proposed by the present utility model is:
[0015] A roof inner gutter 5 node includes an inner gutter 5 with one end arranged between the wall purlin 3 and the inner side of the parapet wall inner panel 4, one end arranged between the roof panel 1 and the roof eaves purlin 2, a gutter sling 6 having the same shape as the inner gutter 5 and arranged outside the inner gutter 5, and a metal pressing strip arranged between the bottom surface of the roof panel 1 and the top surface of the roof eaves purlin 2.
[0016] As Figure 1 and Figure 2 shown, the head end of the metal pressing strip is a right-angle plate, the tail end is parallel to the bottom surface of the roof panel 1, the horizontal section of the head end is connected to the roof panel 1 through a self-tapping screw 8, and a connecting section inclined downward is arranged between the head end and the tail end of the metal pressing strip, so that a certain gap is left between the tail end of the metal pressing strip and the bottom surface of the roof panel 1.
[0017] Among them, the gutter sling 6 is mainly used to prevent the inner gutter 5 from sinking and deforming. It can be made of galvanized steel strips. One end of the gutter sling 6 close to the wall purlin 3 is fixed on the wall purlin 3 by self-tapping screws 8. The end of the inner gutter 5 connected to the inner side of the parapet inner panel 4 is L-shaped. The vertical section of the L-shaped end of the inner gutter 5 and the gutter sling 6 are both fixed between the parapet inner panel 4 and the wall purlin 3 by the same self-tapping screw 8.
[0018] Among them, one end of the inner gutter 5 close to the roof eave purlin 2 is horizontal. One end of the gutter sling 6 close to the roof eave purlin 2 is a horizontal section. The horizontal section of the gutter sling 6 is fixed on the horizontal top surface of the roof eave purlin 2 by self-tapping screws 8. Here, the self-tapping screws 8 are preferably flat head self-tapping screws. The horizontal end of the inner gutter 5 close to the roof eave purlin 2 and the horizontal section of the gutter sling 6 are fixed on the roof eave purlin 2 by the same self-tapping screw 8.
