Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a concrete roof eaves termination structure. Background Technology

[0002] When using polymer-coated roof rolls for terminating the eaves of concrete roofs, traditional construction employs metal strips. These metal strips, perpendicular to the drainage direction, inevitably impede water flow. Water obstruction leads to rust, and rust shortens the roof's lifespan. Another new technology uses perforated joint tape, but this involves wet work due to the use of adhesive mortar or polymer cement waterproofing mortar. Therefore, a new technology is urgently needed to address the problems of existing technologies. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this application is to provide a concrete roof eaves termination structure that can both compress the roofing membrane and not block water, and also has a drip function, eliminating the need for decorative painting, allowing for dry construction throughout the process, and is convenient, precise, beautiful and easy to maintain.

[0004] To address the aforementioned problems, this application provides a concrete roof eaves termination structure, comprising: The outward-sloping concrete roof eaves include the upper surface of the eaves, the side surface of the eaves, and the lower surface of the eaves. The slope of the upper surface of the eaves is not less than 1.7%; the side surface of the eaves is perpendicular to the lower surface of the eaves. A polymer waterproof membrane layer extends from the roof upstream to the eaves and at least covers the upper surface and side surface of the eaves. The snap-fit ​​strip is made of weather-resistant PVC and consists of an upper section, a middle section, and a lower section. The middle section is located between the upper and lower sections, and its height corresponds to the height of the eaves side surface. The inner surface of the upper section is provided with multiple longitudinal ridges. The snap-fit ​​strip is installed on the eaves of the concrete roof. The snap-fit ​​strip makes the polymer waterproof membrane layer wrap around the upper surface and side surface of the eaves, and the protrusions press the corresponding part of the polymer waterproof membrane layer tightly onto the upper surface of the eaves.

[0005] In at least one embodiment, the upper section of the snap-fit ​​strip is further provided with multiple screw holes, and a countersunk wood screw is provided in the screw holes. The countersunk wood screw anchors the upper section of the snap-fit ​​strip to the eaves of the concrete roof, and polyurethane sealant is used to seal the nuts of the countersunk wood screws to form a waterproof seal.

[0006] In at least one embodiment, the countersunk wood screw has dimensions of Φ6mm × 40mm.

[0007] In at least one embodiment, the polymer waterproof membrane layer is a self-adhesive polymer membrane, with the edges fixed by rubber plugs and the rubber plugs covered by double-sided butyl tape.

[0008] In at least one embodiment, an inward angle is formed between the lower section and the middle section, such that the end of the lower section is close to the lower surface of the eaves.

[0009] In at least one embodiment, a drainage channel is formed between the ridges.

[0010] In at least one embodiment, the ribs are 4mm wide and 2mm high, with 45-degree chamfered surfaces at both ends, and a 60mm gap between the ribs.

[0011] This utility model adopts a specially designed roll end clamping component. The clamping component can tighten the roll without blocking water, and also has a dripping function. The entire process is dry, convenient, precise, beautiful and easy to maintain. Attached Figure Description

[0012] Figure 1 The figure shown is a cross-sectional view of a concrete roof eave termination structure provided in one embodiment of this application; Figure 2 for Figure 1 Top view of the structure shown. Detailed Implementation

[0013] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer and more understandable, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0014] like Figure 1 and Figure 2 The concrete roof eaves termination structure shown has an outward slope, including an upper surface 32, a side surface 33, and a lower surface. The side surface 33 is perpendicular to the lower surface. The slope of the upper surface 32 (slope surface 30) is not less than 1.7%, and the slope of the variable slope surface 31 is not less than 15%. The concrete bottom of the eaves is flat on the upper slope, directly compacted and smoothed, with a longitudinal flatness error of less than 3.0. A construction distance measuring ruler is made according to the hole positions of the pressure strip. Ventilation holes 50 are provided on the concrete roof eaves.

[0015] A polymer waterproof membrane layer 20 is laid on the eaves of the concrete roof. This polymer waterproof membrane layer 20 is a self-adhesive polymer membrane. The polymer waterproof membrane layer 20 covers the eaves from the upstream of the roof and at least covers the upper surface 32 and the side surface 33 of the eaves. A series of effective measures should be taken to ensure that the membrane is firmly adhered and does not shift above the slope change. The edges are fixed with rubber plugs. If the polymer membrane is laid loosely, the upstream membrane can be anchored horizontally with special pressure strips first, and then firmly adhered along the entire length at the slope change point with double-sided butyl tape. The membrane should be precisely hung down, cut straight, and the edges are firmly fixed with rubber plugs. A Φ50 double-sided butyl rubber ring is pre-adhered on the rubber plug, and then the plug is pasted while aligning the holes, so that the membrane and the rubber plug holes correspond one by one. The rubber plug is made of nylon plastic. Before inserting the rubber plug, the powder is blown away, and the outer surface is thinly coated with JS.

[0016] A retaining strip 10 is provided at the end of the concrete roof eaves and the polymer waterproof membrane layer 20. The retaining strip 10 is made of weather-resistant PVC, is 1500mm long, and has screw holes with a hole spacing of 300mm and a hole diameter of Φ6mm, symmetrically arranged in the center. The retaining strip is installed on the concrete roof eaves, and the retaining strip causes the polymer waterproof membrane layer 20 to wrap around the upper surface 32 and the side surface 33 of the eaves. The protruding rib 14 presses the corresponding part of the polymer waterproof membrane layer 20 tightly against the upper surface 32 of the eaves. The retaining strip 10 includes an upper section 11, a middle section 12, and a lower section 13. The middle section 12 is located between the upper section 11 and the lower section 13. The height of the middle section 12 corresponds to the height of the side surface 33 of the eaves. The lower section 13 forms an inward angle with the middle section 12, so that the end of the lower section 12 is close to the lower surface of the eaves. The inner surface of the upper section 11 of the clamping strip 10 is provided with multiple longitudinal ribs 14; drainage channels are formed between the ribs. The ribs 14 are 4mm wide and 2mm high, with 45-degree chamfered surfaces at both ends, and a 60mm gap is formed between the ribs.

[0017] A countersunk wood screw 40 is installed in the screw hole of the upper section 11 of the clamping strip 10. The countersunk wood screw 40 anchors the upper section 11 of the clamping strip 10 to the concrete roof eaves, and polyurethane sealant is used to seal the nut of the countersunk wood screw 40, forming a waterproof seal. The dimensions of the countersunk wood screw 40 are Φ6mm×40mm. The clamping strip is anchored section by section. After anchoring, the nut is sealed with white polyurethane sealant. This includes applying Φ20mm perforated masking tape to maintain an aesthetic appearance.

[0018] This utility model adopts a specially designed roll material end clamping component. The clamping component can tighten the roll material without blocking water, and also has a water dripping function. It replaces the finishing paint, allowing for a completely dry operation that is convenient, precise, beautiful, and easy to maintain.

Those skilled in the art can implement the present invention in various modifications without departing from its scope and spirit; for example, a feature of one embodiment can be used in another embodiment to obtain yet another embodiment. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention should be within the scope of the present invention.
