Description

Technical Field

[0001] The present application relates to the field of prefabricated buildings, and in particular to a metal roof and ridge sealing structure. Background Art

[0002] Metal roofs have the characteristics of high strength, good durability, and recyclable materials. With the vigorous development and promotion of prefabricated buildings, metal roofs are widely used in various industrial, commercial and civil building exterior protection projects.

[0003] Waterproof sealing has always been the focus of attention during the construction and use of metal roofs. If leakage occurs, it may cause a series of problems such as economic losses. Under normal circumstances, due to the characteristics of the large panel surface, the risk of leakage in the seepage roof is relatively small, and the potential leakage hazards are mainly concentrated in various node positions such as edge closing, and the ridge is one of the key points. The vertical lock-edge metal seat forms a vertical plate rib protrusion. The traditional method is to process an integral ridge cover plate. Usually, the bottom of the side of this plate cannot fit the path of the roof outer plate, and a large gap is formed between the roof outer plate surface after installation. During the on-site installation process, the plate ribs are cut and bent, and fixed with a Z-shaped bracket. Due to the on-site processing operation errors of the workers, the accuracy of the plate edge is uncertain, and the sealing performance cannot be guaranteed. At the same time, at this node, the side of the ridge is not fixed, and the shape is maintained only by the rigidity of the plate, which poses a risk of leakage. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0034] In order to solve the technical problem in the related technology that the ridge node of the metal roof is poorly sealed and easy to leak due to the secondary processing assembly error and the lack of support on the side of the ridge cover plate 8, the present application provides a metal roof and ridge sealing structure, which can improve the sealing performance of the ridge node and effectively reduce the risk of leakage at the ridge of the metal roof.

[0035] The present application is described below in conjunction with the accompanying drawings and embodiments. The width direction of the ridge cover plate 8 referred to in the present application refers to the direction in which the ridge cover plate 8 spans the front and rear sides of the ridge, that is, the direction in which the double-slope metal roof extends from the front slope to the rear slope; the width direction of the roof outer plate 3 refers to the direction parallel to the length direction of the ridge after the roof outer plate 3 is installed in place, and the length direction of the roof outer plate 3 is perpendicular to the width direction of the roof outer plate 3.

[0036] like Figures 1 to 3 As shown, the embodiment of the present application provides a ridge sealing structure, which mainly includes a rib plate clamp 4, a sealing plate assembly and a ridge cover plate 8. The ridge sealing structure can be fixed at the ridge through the roof outer plate 3 of the metal roof, forming a good shielding seal at the ridge, and improving the anti-leakage performance of the metal roof at the ridge. After the roof outer plate 3 of the metal roof is installed in place, the side edges of the adjacent roof outer plates 3 are fixed to the locking support 2 to form upright plate ribs through locking. The ridge sealing structure provided by the embodiment of the present application adopts the rib plate clamp 4 to directly clamp and fix the upright plate ribs on the roof outer plate 3, and at the same time, the sealing plate assembly is installed and fixed with the help of the rib plate clamp 4. The sealing plate assembly can be symmetrically arranged at the corresponding positions of the front slope and the rear slope on both sides of the ridge of the double-slope metal roof, and then the ridge cover plate 8 is arranged above the ridge, and the side edges on both sides of the ridge cover plate 8 are sealed and connected to the sealing plate assemblies on both sides of the ridge.

[0037] The bottom of the sealing plate assembly fits the upper surface of the roof outer plate 3, and a relatively sealed space covering the ridge is formed between the sealing plate assembly and the ridge cover plate 8, thereby improving the anti-leakage performance at the ridge.

[0038] The embodiment of the present application uses the rib plate clamp 4 to clamp and fix on the upright plate rib formed at the connection of the roof outer plate 3, without the need for cutting, bending and secondary processing of the upright plate rib, thereby reducing assembly errors and improving assembly accuracy and sealing performance.

[0039] Combined with reference Figure 1 , Figure 5 and Figure 6 In some embodiments, in order to facilitate the installation and fixation of the sealing plate assembly to the rib clamp 4 and the connection and sealing between the sealing plate assembly and the ridge cover plate 8, the sealing plate assembly can adopt a structure composed of a sealing plate upper bracket 5, a sealing plate lower bracket 6 and an inter-rib sealing plate 7. Among them, the sealing plate upper bracket 5 is fixedly connected to the top of the inter-rib sealing plate 7, and the sealing plate lower bracket 6 is fixedly connected to the bottom of the inter-rib sealing plate 7; in other words, the sealing plate assembly uses the sealing plate upper bracket 5 and the sealing plate lower bracket 6 to clamp and fix the inter-rib sealing plate 7 from the upper and lower directions. The sealing plate upper bracket 5 and the sealing plate lower bracket 6 are both fixed by the rib clamps 4 on both sides of the roof outer panel 3, so that the sealing plate assembly is fixed to the roof outer panel 3 of the metal roof through the rib clamps 4, and the sealing plate assembly supports the side of the ridge cover plate 8, and at the same time, the gap between the side of the ridge cover plate 8 and the roof outer panel 3 is shielded and sealed to a certain extent.

[0040] like Figure 3 As shown, the roof outer panel 3 is a structure with two sides turned up and convex relative to the main body, in order to improve the fit between the sealing plate assembly and the roof outer panel 3. The bottom shape of the sealing plate assembly is adapted to the cross-sectional contour shape of the upper surface of the roof outer panel 3. That is, the bottom of the intercostal sealing plate 7 is adapted to the cross-sectional shape of the upper surface of the roof outer panel 3, the sealing plate lower bracket 6 is adapted to the bottom of the intercostal sealing plate 7 and the cross-sectional shape of the upper surface of the roof outer panel 3, and the sealing plate lower bracket 6 is fitted between the bottom of the intercostal sealing plate 7 and the upper surface of the roof outer panel 3. During assembly, sealant can also be injected between the bottom of the sealing plate assembly and the upper surface of the roof outer panel 3 according to actual needs. The above-mentioned sealing plate assembly can be pre-assembled and formed. During the metal roof assembly process, after the installation and locking of the roof outer panel 3 are completed to form the upright plate ribs, the sealing plate assembly is installed and fixed to the roof outer panel 3 through the rib clamp 4.

[0041] It is understandable that the sealing plate assembly can not only adopt the combined structure of the sealing plate upper bracket 5, the inter-rib sealing plate 7 and the sealing plate lower bracket 6 disclosed in the above embodiment, but can also be set as an integrated structure as needed. When the sealing plate assembly adopts an integrated structure, the top of the sealing plate assembly meets the connection and sealing requirements of the ridge cover plate 8, the bottom of the sealing plate assembly meets the fitting requirements with the upper surface of the roof outer plate 3, and the two ends of the sealing plate assembly meet the requirements of fixed connection with the rib plate clip 4. The specific structure can be adjusted according to actual needs.

[0042] In some embodiments, see Figure 1 and Figure 7 , the ridge cover plate 8 is extended to the side edges on both sides of the ridge and is provided with U-shaped hook edges 801, and the top of the sealing plate assembly is provided with a first connecting flange, and the first connecting flange extends toward the side away from the ridge. The main part of the sealing plate assembly is substantially perpendicular to the roof outer panel 3, and the first connecting flange is substantially perpendicular to the main part of the sealing plate assembly or parallel to the main part of the roof outer panel 3. The ridge cover plate 8 is hooked and fixed to the first connecting flanges on the sealing plate assembly on both sides of the ridge through the U-shaped hook edges 801 on both sides. When the sealing plate assembly adopts a structure in which the sealing plate upper bracket 5, the intercostal sealing plate 7 and the sealing plate lower bracket 6 are combined, the first connecting flange is arranged on the top of the sealing plate bracket 5, or the first connecting flange is arranged on the top of the sealing plate bracket 5 and the sealing plate lower bracket 6 at the same time, and the first connecting flange of the sealing plate bracket 5 and the first connecting flange on the top of the intercostal sealing plate 7 are arranged to overlap each other. The ridge cover plate 8 can be a plate-like structure as a whole, or the ridge cover plate 8 can be set to have a certain curvature, such as a double slope shape with a high middle and low sides. The slope can be flexibly set as needed to meet drainage requirements.

[0043] Furthermore, the ridge sealing structure also includes a first fastener, which can be a self-tapping screw, which is used to penetrate the U-shaped hook edge 801 and the first connecting flange from top to bottom in sequence, thereby improving the connection sealing performance between the ridge cover plate 8 and the sealing plate assembly. In addition, a waterproof rubber ring can be provided on the end of the self-tapping screw that fits the ridge cover plate 8, that is, on the upper outer surface of the U-shaped hook edge 801, and the self-tapping screw or the first fastener penetrates the waterproof rubber ring and penetrates the U-shaped hook edge 801 and the first connecting flange.

[0044] The ridge cover plate 8 can be set as a cover plate structure with moderately adjustable width, such as a plate with certain grooves or folds formed by stamping, so that the ridge cover plate 8 can be moderately stretched and contracted along its width direction, which is convenient for the U-shaped hooks 801 on both sides of the ridge cover plate 8 to be hooked and connected with the first connecting flange of the sealing plate assembly. Exemplarily, the ridge cover plate 8 is provided with a convex groove in the center of the width direction, and the convex groove is convexly extended toward the upper surface of the ridge cover plate 8, that is, the surface away from the ridge, so that the span of the side of the convex groove can be elastically increased and decreased, and the moderately adjustable width of the ridge cover plate 8 can be achieved by adjusting the span of the convex groove. The upward convex groove is convenient for the ridge cover plate 8 to drain water to both sides.

[0045] The setting of rib clamp 4 can refer to Figure 1 and Figure 4 The rib plate clamp 4 includes a first clamping side 401 and a second clamping side 402. One end of the first clamping side 401 and the second clamping side 402 are hinged by a hinge, and a clamping cavity is formed between the two. The setting of the clamping cavity is adapted to the vertical plate rib to ensure that the rib plate clamp 4 can be clamped and fixed to the vertical plate rib. The first clamping side 401 and the second clamping side 402 are aligned to open locking holes. After the first clamping side 401 and the second clamping side 402 are clamped in place, bolts are used to pass through the locking holes of the first clamping side 401 and the second clamping side 402 to lock and fix the rib plate clamp 4 to the vertical plate rib.

[0046] In some embodiments, in order to facilitate the fixing of the sealing plate assembly to the rib plate clamp 4, a second connecting flange 403 is provided at one end of the first clamping side 401 and the second clamping side 402 away from the ridge. From a top view, the rib plate clamp 4 is in a T-shape that is generally symmetrically arranged, that is, one side of the rib plate clamp 4 is in an L-shape, a keyway is provided at the corresponding position of the second connecting flange 403, and a first reserved hole 404 and a second reserved hole 405 are provided at the keyway. Exemplarily, the second connecting flange 403 is provided with a second reserved hole 405 near the bottom of the roof outer panel 3, and the first connecting flange is provided with a first reserved hole 404 away from the top of the roof outer panel 3, and the first reserved hole 404 and the second reserved hole 405 can be arranged in pairs, so that the upper bracket 5 of the sealing plate is fixed to the second connecting flange 403 through the first reserved hole 404 and fasteners such as bolts, and the lower bracket 6 of the sealing plate is fixed to the second connecting flange 403 through the second reserved hole 405 and fasteners such as bolts.

[0047] In addition, the closing plate assembly can not only be fixed relative to the rib clamp 4 by cooperating with fasteners such as bolts through the first reserved hole 404 and the second reserved hole 405, but also a plug-in fitting structure that cooperates with each other can be set at the end of the rib clamp 4 away from the ridge and the end of the closing plate assembly close to the rib clamp 4.

[0048] like Figure 1As shown, the present application also provides a metal roof, including the above-mentioned ridge sealing structure, and also including purlins 1, locking supports 2 and roof outer panels 3. Third connecting flanges 301 are provided at both sides of the width direction of the roof outer panels 3, and the third connecting flanges 301 extend upwardly at an angle relative to the main part of the roof outer panels 3. After the third connecting flanges 301 of adjacent roof outer panels 3 are fixed to the locking supports 2, they are locked together to form vertical plate ribs, and the ridge sealing structure is clamped and fixed at the vertical plate ribs of the roof outer panels 3 by rib plate clamps 4. Other parts of the metal roof can be set with reference to the prior art, and the present application will not expand on this.

[0049] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the appended claims.
