Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a roof R-corner flashing shaping mold. Background Technology

[0002] Roof flashing refers to a protective structure that effectively guides rainwater from the roof to drainage points through flashing construction, preventing water from seeping into the area where the roof meets the walls.

[0003] Currently, the most common method for roof flashing treatment in engineering projects is to lay the waterproof membrane along the roof plane and then flip it up directly towards the flashing area on the facade, connecting it to the parapet wall or other facade components. This right-angle flip-up connection method is relatively simple in terms of construction technology, but expansion joints cannot be set between the rigid layer and the facade. If joints are set, the membrane is prone to hollowing, curling, or even falling off completely at the flip-up point on the facade, thus causing potential leakage risks.

[0004] Some projects employ rounded-corner flashing, which involves creating an arc-shaped transition at the junction of the roof and facade, and then applying a protective layer using plastering. This method helps reduce deformation concentration at the bulging areas of the roofing membrane, resulting in a more reasonable stress distribution. However, the construction of rounded-corner flashing relies heavily on manual plastering on-site. The process is highly dependent on the experience and skill level of the workers, making it difficult to guarantee the straightness and consistency of the curve. Defects such as excessive thickness, insufficient thickness, and misalignment can easily occur, affecting the subsequent adhesion and service life of the roofing membrane.

[0005] Patent CN218894305U discloses a roof corner flashing plastering structure. In use, cement mortar is filled into the frame. After filling, pushing the handle moves the plastering frame, which corrects the corner flashing. However, scraped cement mortar easily enters the guide channel. Although the design includes a cleaning block to clean the cement mortar inside the frame, cement mortar particles inevitably enter the gap between the plastering frame and the guide channel, causing the frame to jam. Furthermore, if not cleaned promptly, the plastering frame becomes difficult to move after the cement mortar hardens, resulting in high maintenance costs. Utility Model Content

[0006] The purpose of this utility model is to provide a roof R-corner flashing shaping mold to solve the problems mentioned in the prior art.

[0007] A roof r-corner flashing shaping mold is provided, comprising: A molded upright plate has an arc-shaped guide surface and two path guide surfaces formed on it, with the two path guide surfaces respectively disposed at both ends of the arc-shaped guide surface.

[0008] Furthermore, it also includes two guide rails respectively disposed on the roof and the facade, and the two path guide surfaces can respectively fit into the surfaces of the two guide rails.

[0009] By fitting the guide rails to the path guide surface, a controllable sliding path is provided for the forming plate mold, enabling the entire forming process to have a pre-set motion trajectory. This ensures the guiding accuracy of the mold's movement during forming, allows for repeatable construction paths, and reduces the uncertainty of construction work that relies on workers' experience.

[0010] Furthermore, a stop plate is provided at the top of the guide rail located on the roof.

[0011] The stop plate restricts the backward freedom of the forming panel, preventing the forming panel from shifting away from the facade due to operational errors during manual operation, or causing the forming panel to rotate around the roof guide rail as a fulcrum, which would affect the forming accuracy.

[0012] Furthermore, a handle portion is provided on the molded upright plate.

[0013] The handle is easy to grip or push / pull manually, allowing the entire mold to slide within the guide rail.

[0014] Furthermore, the sidewall of the molded upright plate is provided with a traction part.

[0015] A traction component is installed on the side of the forming plate, which can be used for linear pulling to provide axial traction force, reduce the deflection and movement of the forming plate caused by eccentric operation, and achieve directional operation by improving the rationality of force distribution.

[0016] Furthermore, the traction unit includes a chain connected to the forming plate.

[0017] The chain flexibly connects the molded uprights and provides a traction source, avoiding interference between the rigid traction part and the facade at the corner position when the molded uprights are transitioning to the facade corners. This enables flexible transmission and adaptive movement of the molded uprights in the transition zone, and can cope with the terrain changes of different construction sites.

[0018] Furthermore, the chain can be detachably connected to both sides of the molded upright plate.

[0019] Both sides of the molded upright plate are equipped with chain connection structures, which allow the chains to be installed and removed from both sides, and allow for free selection of traction direction or installation method under different construction conditions.

[0020] Furthermore, a nut is provided on the forming plate, and a screw is provided at the end of the chain. The screw can be threadedly connected to the nut from both sides of the forming plate.

[0021] The screw, through its threaded engagement with the nut, provides a convenient, stable, and adjustable chain connection structure, preventing disengagement or swaying during construction and ensuring stable traction.

[0022] Furthermore, the nut penetrates through the molded vertical plate.

[0023] The nut penetrates the entire thickness of the vertical plate, and the screw can be threaded into the nut from both ends of a single nut, which can increase the screw's insertion depth.

[0024] Furthermore, a pull ring is provided at the end of the chain away from the forming plate.

[0025] As the gripping or connecting part at the end of the chain, the pull ring allows for manual or tool-assisted force application, simplifying the traction operation for on-site personnel and improving construction efficiency.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: The molding panel defines the geometry of the plaster outline by integrating curved guide surfaces and path guide surfaces. The curved guide surfaces provide the R-angle transition curve, while the path guide surfaces define the construction direction. This achieves standardized R-angle shape molding, avoiding uneven lines and thicknesses caused by manual construction, and improving the linear and surface consistency of the flashing molding.

[0032] However, there may be instances where unnecessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters or repetitive descriptions of essentially the same structures may be omitted. This is to avoid unnecessarily lengthy descriptions and to facilitate understanding by those skilled in the art. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0033] Please see Figure 1 As shown in the embodiment of this utility model, a roof R-corner flashing shaping mold includes a forming plate 1, on which an arc-shaped guide surface 11 and two path guide surfaces 12 are formed, and the two path guide surfaces 12 are respectively disposed at both ends of the arc-shaped guide surface 11.

[0034] The forming plate 1 is a plate-like structure and serves as the main supporting component of the entire mold. It acts as the carrier for the arc-shaped guide surface 11 and the path guide surface 12, providing stable and rigid spatial definition for the flashing transition area. The arc-shaped guide surface 11 matches the R-angle geometry at the junction of the roof and the facade, guiding the plaster layer to form a smooth and uniform arc-shaped transition between the roof and the facade. The path guide surface 12 is located at both ends of the arc-shaped guide surface 11 and guides the sliding trajectory of the mold in the horizontal direction, thus defining the movement path and maintaining forming accuracy.

[0035] In one embodiment, the molded vertical plate 1 is placed against the intersection of the roof and the facade, and the path guide surfaces 12 are respectively attached to the pre-set guide planes. Cement ash or plastering material is evenly applied to the R-corner area. The molded vertical plate 1 is pushed slowly along the path guide surface 12, so that the arc-shaped guide surface 11 continuously scrapes the material to form a smooth and consistent R-corner contour during the sliding. After the material is shaped, the mold is removed, and the arc-shaped flashing area is formed. The formed flashing R-corner is linear and straight with uniform thickness.

[0036] The mold also includes two guide rails 2 respectively installed on the roof and the facade, with two path guide surfaces 12 that can respectively fit into the surfaces of the two guide rails 2. It should be noted that the facade is a parapet wall or other facade component, and the surfaces of the guide rails 2 temporarily fixed to the facade and the roof are perpendicular to each other. The guide rails 2 can be made of wood or steel formwork, and are long strip structures extending horizontally along the facade and roof.

[0037] Specifically, two guide rails 2 are temporarily fixed to the roof and facade, respectively. Two path guide surfaces 12, as integral structures on the forming plate 1, are respectively attached to the two guide rails 2. Through structural constraints, a mutually cooperating sliding guide system is formed between the two, controlling the movement trajectory of the mold and limiting the sliding direction of the forming plate 1 within a preset trajectory to prevent deviation or torsion. This ensures that the arc-shaped guide surface 11 repeatedly scrapes the surface along the same trajectory during the forming process, guaranteeing the continuity and consistency of the radius (R-angle). In addition, since the forming plate 1 and guide rails 2 are separate structures, the contact surface between the path guide surface 12 and guide rails 2 is fully exposed, allowing for easy cleaning of the mating surfaces, ensuring the template can be reused, and reducing maintenance costs.

[0038] Furthermore, a stop plate 21 is provided at the top of the guide rail 2 on the roof. The stop plate 21 is located at the top of the guide rail 2, away from the facade, and extends along the length of the guide rail 2. During the manual pushing of the mold, operations such as pulling backward, releasing, or rebounding may occur. The stop plate 21 acts as a physical limiter to prevent the mold from retreating or deviating out of control. If the forming plate 1 is subjected to uneven force during construction, it may rotate or tilt slightly with the roof guide rail 2 as the fulcrum. The stop plate 21 can provide additional support or abutment points at key locations, thereby suppressing the rotation tendency of the forming plate 1 around the guide rail 2.

[0039] A through hole is provided on the forming plate 1, and a handle part 13 is formed between the edge of the forming plate 1 and the through hole, which can be held and operated by the operator.

[0040] The side wall of the forming plate 1 is provided with a traction part 14, which is held by the operator to apply traction force from the side of the forming plate 1.

[0041] In one embodiment, the operator holds the handle 13 with one hand, ensuring that the two path guide surfaces 12 on the molding plate 1 are respectively in close contact with the two guide rails 2; with the other hand, the operator holds the traction unit 14, applying a traction force extending along the R-angle flashing length direction to the molding plate 1 through the traction unit 14. That is, the handle 13 maintains the posture of the molding plate 1 and applies partial traction force, while the traction unit 14 provides the main traction force, ensuring that the arc-shaped guide surface 11 always moves stably along the predetermined path, ensuring the straightness and curvature consistency of the line.

[0042] The traction unit 14 can be a rigid rod connected to the forming plate 1, or it can be a flexible chain 141 connected to the forming plate 1. When the mold transitions to the vertical turning point, if a rigid traction rod is used, problems such as interference between the structure and the vertical surface or inability to turn the corner may occur at the corner. However, using a flexible chain 141 can achieve a smooth transition. The chain 141 can bend naturally around the corner position, keeping the forming plate 1 and the guide rail 2 in close contact, and the forming posture is not interfered with by the traction structure.

[0043] A pull ring 144 is provided at the end of the chain 141 away from the forming plate 1. By setting a clear force application interface at the end of the chain 141, manual operation is made more stable and reliable, thereby improving the efficiency and safety of the chain 141 system in traction, connection and suspension operations.

[0044] Furthermore, the chain 141 connection structure is symmetrically arranged on both sides of the molded upright plate 1, and the chain 141 can be loaded and unloaded from either side. The double-sided chain 141 connection structure allows the operator to complete the traction operation of the chain 141 from either side according to the site conditions, improving installation efficiency and work convenience, and realizing flexible deployment of the traction path.

[0045] Nuts 142 are provided on the forming plate 1, and screws 143 are provided at the end of the chain 141. The screws 143 can be threaded to the nuts 142 from both sides of the forming plate 1. The adjustable characteristics of nuts 142 and screws 143 facilitate quick installation or disassembly on site, avoiding the use of welding or one-time pin connections, which are difficult to replace.

[0046] In one specific embodiment, two nuts 142 are respectively welded to both sides of the forming plate 1, and the threaded holes of the two nuts 142 are separated by the forming plate 1.

[0047] In one specific embodiment, a single nut 142 penetrates through the forming plate 1, and the threaded holes on both sides of the forming plate 1 are interconnected. The two ends of the single nut 142 can be threaded into screws 143 from different directions. Compared to two independent nuts 142 respectively assembled on both sides of the forming plate 1, this structure achieves fixation at both ends through a single integral nut 142, improving assembly accuracy and coaxiality.

[0048] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
