High-strength buckle roof metal sheet

This creation is a high-strength buckle roof metal plate; especially a special design of the fixed seat, so that the metal plate can be overlapped to hide the fixed seat, the metal plate is free of screw fixing, high wind pressure resistance and metal plate High-strength buckle roof metal sheet for the effect of water seepage due to siphoning.

Concealed steel plates commonly found in the market, such as Taiwan's new bulletin No. M382348 "roof steel plate hidden snap-on fasteners", M348802 "hidden stranded one-piece steel plate (1)", M348803 "hidden twisted one Molded steel plate (2) and M348804 "hidden stranded integral steel plate (3)", which are first fixed to the steel frame by the fixing seat, and then the two adjacent steel plates are overlapped above the fixed seat, and then utilized The tool hinges and fixes the overlap between the two steel plates to hide the fixing seat and protect the steel plate from locking screws.

However, these conventional concealed steel plates have many problems in use, which are described as follows:

First, the conventional concealed steel plate is hinged and fixed only to the lower fixing frame of the two steel plates, that is, except for the hinge, there is no fixed structure elsewhere in the steel plate, so the non-hinge of the steel plates Very easy to be blown by the wind. In this way, when the building encounters strong winds (such as typhoons), the strong wind pressure will blow the steel plate first, so that the wind receiving surface of the steel plate will increase instantaneously. When the steel plate is unable to withstand the wind pressure, the steel plate will be caused. It is not practical to be picked up or blown away, resulting in public safety problems and property losses.

Secondly, the structure of the conventional concealed steel plate fixing structure has only two structures of a steel plate lap joint and a steel frame lock portion, so that only the lap joint of the steel plate can be connected with the building structure and the effect of fixing the steel plate is obtained. The purpose of the concealed steel plate design is to hide the screws and the fixed seat locked on the steel plate, so it is impossible for the hidden steel plate to improve the stability of the steel plate by means of a locking screw.

Thirdly, the conventional steel plate joints are hinged and fixed, which will make the steel plate and the steel plate and the steel plate and the fixed seat closely fit together. Thus, when it rains, between the steel plate and the steel plate and between the steel plate and the fixed seat The siphon phenomenon occurs due to the close fitting, so that the external rainwater is sucked into the interior of the building through the hinge of the steel plate, causing problems such as water leakage, rust, moldy and stinky inside the building, and the building becomes Moist and reduce the quality of living.

To this end, the creator, in response to the problems of the hidden cover steel plate, has accumulated many years of steel plate R & D and manufacturing experience and created the case.

The purpose of this creation is to use the second snap portion of the rotatable mount to strengthen the snap-fit of the metal plate, providing more fastening points than the conventional hidden steel plate to achieve HSB (ie High Strength) Buckle, high-strength fastening) level of the fastening effect; and the metal plate and the fixed seat need not be fixed, the design of the fixed seat snap groove, so that the metal plate through the metal plate and the fixed seat during thermal expansion and contraction The relative sliding generated is used for buffer adjustment to effectively prevent deformation of the metal plate; further, the second snap groove provided in the fixing seat can not only enhance the engagement strength between the metal plate and the fixed seat, when it is raining The water infiltrated by the rainwater through the overlapping of the adjacent two metal plates is also introduced into the second buckle portion of the lower metal plate to be discharged, so as to solve the long-term water seepage problem of the conventional hidden steel plate.

As shown in Figures 1 and 11 to 14, the high-strength roof metal sheet of the present invention is implemented by locking the fixing seat 1 on the lower structure. At this time, the construction personnel must calculate the required wind pressure design according to the construction environment. And arranging the plurality of screws 3 at appropriate positions, so that the fixing base 1 can be firmly combined with the lower structure (as shown in FIGS. 11 and 12); then the first card of the first overlapping portion 21 of the metal plate 2 can be obtained. The fastening portion 211 is press-fitted into the first locking slot 11 of the fixing base 1 , and the second fastening portion 212 of the metal plate 2 is inserted into the second locking slot 14 of the fixing base 1 , and then the fixing seat is fixed. The second joint portion 13 of the first joint portion 12 is rotated in the direction of the first joint portion 12, so that the recessed portion 120 of the first joint portion 12 and the recess portion 130 of the second joint portion 13 jointly clamp the second buckle of the metal plate 2 a portion 212 (shown in FIGS. 13 and 14); finally, the third fastening portion 221 of the second overlapping portion 22 of the other adjacent metal plate 2 can be pressed into the third buckle fastened to the fixing seat 1. In the slot 15, the cover portion 222 is wrapped over the fixed seat, and then the first hook of the corresponding fixed seat 1 is hooked and fastened by the hook portion 223 Position of the card 11 of the engagement portion 110 (FIG. 1 and 14), to complete the assembly of overlapping sheet metal roofing.

In this way, the high-strength roofing metal sheet of the present invention utilizes the design of the rotatable second fastening portion 212 to strengthen the metal plate 2 to be fastened and fixed, and can provide far more than the conventional hidden steel plate (only two or three buckles) More fastening points (ie, two fastening points of the first locking groove 11 , one or two fastening points of the second locking groove 14 , and the third fastening groove 15 ) The fastening strength of the HSB (ie High Strength Buckle) is achieved by the five or six fastening points presented by the two fastening points; and between the metal plate 2 and the fixed seat 1 Without the need of locking or welding fixing, the design of the retaining seat 1 snap groove allows the metal plate 2 to undergo thermal expansion and contraction due to weather changes, and the relative sliding of the metal plate 2 and the fixed seat 1 is performed. The buffer is adjusted to effectively prevent deformation of the metal plate 2 and affect the overall structural safety.

Furthermore, the second snap groove 14 of the present invention not only enhances the engagement strength between the metal plate 2 and the fixed seat 1, but also absorbs the moisture absorbed by the rain through the overlapping of the adjacent two metal plates 2 when it rains. It is also introduced into the second fastening portion 212 of the lower metal plate 2 to be discharged in order to solve the problem of water seepage in the conventional hidden steel plate, and the independent space formed by the second fastening portion 212 is small. Under the influence of external wind pressure, it has better practicality and economic benefits, and is the composition of this case.

The above-mentioned embodiments or the drawings are not intended to limit the scope of the present invention, and any suitable variations or modifications of the ordinary skill in the art should be considered as not departing from the scope of the invention.
