And (3) removing the roof board, and finding out that the C13 position support screw is pulled out and the support falls off after the static anti-wind uncovering test. The ultimate wind load detection damage value is-16502 Pa, and the design load requirement is met.
Firstly, it can be determined that after the wind uncovering-resistant roof system in the strong wind area is adopted, the wind load of the whole roof is greatly improved to-15335 Pa, which is unprecedented in the industry, and the industry does not have the arrangement in typhoon areas which possibly occur along the coast, and then the encryption purline 53 is further arranged, so that the wind load of the whole roof is improved on the original basis, the wind load of the whole roof is-16502 Pa, and the wind resistance of the whole roof system is greatly enhanced.
In the embodiment of the present invention, as shown in fig. 6, the encrypted purline 53 is a transverse encrypted purline 53A, and the transverse encrypted purline 53A and the several-shaped purlines 52 form a plurality of rectangular frames, so that the density of the whole supporting layer 5 is higher by arranging the transverse encrypted purline 53A, the original large rectangular frame is changed into a plurality of small rectangular frames, and when the pressure is applied, the pressure applied to the supporting layer can be uniformly dispersed everywhere, thereby better improving the wind resistance.
In another embodiment of the present invention, as shown in fig. 7, the encrypted purlin 53 is a special-shaped encrypted purlin 53B, the special-shaped encrypted purlin 53B includes a plurality of sequentially connected encrypted rods 3B1, and longitudinal connecting rods 3B2 locked at two ends of the encrypted rods 3B1 by locking members 10, and wind-force divergence in multiple directions and multiple angles can be formed by the design of the encrypted rods 3B1, preferably, the encrypted rods 3B1 and the encrypted rods 3B1 are in tenon connection, and different encrypted rods 3B1 and 3B1 are in tenon connection in different directions, compared with the design of simple welded connection, cracks and drops are not easy to occur when the encrypted rods are subjected to vibration or external pulling force, and the directions in different directions are because the wind directions are changed at any time, and the directions of strong wind caused by different ocean currents and subsidiary hot-band high pressures are extremely uncertain, so that the connection and fixation are required to be performed in extension in each direction in consideration of wind-resistance performance in each direction.
In order to make the encryption rod 3B1 extending in various directions available, the locking member 10 is used to lock the longitudinal connecting rods 3B2 at two ends of the encryption rod 3B1, two ends of the longitudinal connecting rods 3B2 are connected to the n-shaped purlines 52, and the pressure received from the encryption rod 3B1 can be dispersed to the n-shaped purlines 52 through the longitudinal connecting rods 3B2, so that the pressure applied to a small structure can be dispersed to a large structure, and the situation that the deformation of the small structure gradually affects the stability of the large structure is avoided.
On many metal roofing connection structures of current, often in order to improve the degree of integration, connect through same connection structure, perhaps directly offer all locating holes on same straight line, the drawback of this aspect is with all locking nodes concentrate on same line, then when other connected nodes receive to tear the power and torsion, the phenomenon of deformation appears easily, so in this case will locking piece 10 on roofing purlin 1, locking piece 10 on the several words purlin 52, locking piece 10 on fixing base 8 all are not in same vertical line, produce two beneficial effects, and one effect is the node dispersion with the locking, makes a plurality of faces all can receive the locking effect of locking node, and another effect is the intensity on will be avoided punching on same straight line thereby destroying this section vertical line, concentrate on this section vertical line from the wind pressure, then easily regard this as broken point, forms the phenomenon of broken face of point.
The above-mentioned structures are formed by fixing and connecting the roof and the like, but in practice, in a strong wind area, the whole roof is usually uncovered by strong wind force, the position of wind uncovering occurs on the side surface, and the whole roof is lifted from the side surface, so in order to strengthen the whole system from the side surface, the outside of the roof board 9 is locked and fixed with the fixing seat 8 through the first elastic outer rib 90, the first elastic outer rib 90 is provided with the first transverse slot 901, the first transverse slot 901 is fixedly clamped with the second elastic outer rib 91, the top of the second elastic outer rib 91 is locked on the fixing seat 8, the bottom is locked on the encrypted purlin 53, the second elastic outer rib 91 is provided with the second transverse slot 911, the third elastic outer rib 92 is fixedly clamped in the second transverse slot 911, the top of the third elastic outer rib 92 is locked on the encrypted purlin 53, and the bottom of the third elastic outer rib 92 is locked with the roof board 2.
With the above side connection structure, firstly, it needs to be emphasized that the first elastic outer rib plate 90, the second elastic outer rib plate 91 and the third elastic outer rib plate 92 respectively correspond to the first fixed module, the second fixed module and the third fixed module, the point-to-point fixing is respectively performed on the three combined fixed modules, specifically, the upper end and the lower end of the elastic outer rib plate are respectively provided with an ear plate, when the first elastic outer rib plate 90 is installed, the upper ear plate of the first elastic outer rib plate 90 is locked with the roof panel 9, the lower ear plate of the first elastic outer rib plate 90 is locked on the fixing seat 8, and as the first elastic outer rib plate 90 is provided with the first transverse slot 901, the second elastic outer rib plate 91 penetrates through the first transverse slot 901 and fixes the upper ear plate thereof on the lower ear plate of the first elastic outer rib plate 90, so as to form a first linking effect, and the third elastic outer rib plate 92 also adopts a fixing mode of the second elastic outer rib plate 91, so that the first elastic outer rib plate 90, the second elastic outer rib plate 91, the third elastic outer rib plate 92 and the first elastic outer rib plate 92 and the third elastic outer rib plate are connected in series with the air-flow resistance system from the outside, and the first air-flow resistance system is required to be fixed, and the first air-flow-break and the second elastic outer rib plate is connected with the first air-flow-resistance system from the outside.
In addition, it is emphasized that the elastic outer rib plates are all composed of elastic steel sheets, have certain elasticity under wind pressure, can be fluctuated along with the filling of wind, deform according to the rhythm of the wind, are not easy to damage, and can be ensured to fall off easily through the embedded mode of the transverse grooves.
And in order to ensure the combination effect of the third elastic outer rib plate 92 and the roof bottom plate 2, the bottom of the third elastic outer rib plate 92 is of a V-shaped structure with an opening facing the roof bottom plate 2, and can be tightly clamped with the roof bottom plate 2, and under the action of wind pressure, the third elastic outer rib plate 92 is only clamped with the roof bottom plate 2 more tightly, so that the third elastic outer rib plate 92 does not become a breakthrough point of the whole elastic outer rib plate structure.
Since the roof plate 9 is at the top and is most easily lifted away, the roof plate 9 comprises a 360-degree snap-lock, the roof plate 9 is snap-connected with the fixing base 8 through the 360-degree snap-lock, and the roof plate 9 is not easily separated from the fixing base 8 through the snap-connection.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
