Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the present embodiment provides a cornice sliding apparatus for an ultra-wide metal roof. The sliding devices are mounted on the left and right sides of the roof main structure so that the roof panels 4 can span across the device. The sliding device specifically comprises a cornice attachment 1, an intermediate cover plate 2 and a locking connection unit 3. Eaves mouth connecting piece 1 is fixed on the top of purlin 5, and middle apron 2 is fixed at roof boarding 4's lower surface, and eaves mouth connecting piece 1 and middle apron 2 have realized the relative slip of roof boarding 4 and roofing main structure department through relative slip, need not to adopt traditional expansion joint structure again and also can avoid the bad harm that causes of the deformation that expend with heat and contract with cold arouses.
As shown in fig. 2, the cornice attachment 1 is provided with at least two parallel elongated holes 11, two in this embodiment. The length of the elongated hole 11 is generally 5-12 cm, and 8cm is adopted in the embodiment. An n-shaped edge 12 is provided on one side of the cornice attachment 1 and one end of each elongated hole 11 abuts against the n-shaped edge 12. Specifically, the height of the n-type edge 12 is lower than the height of the intermediate cover 2 after being mounted on the cornice attachment 1, and the side of the n-type edge 12 abutting against the elongated hole 11 is an inclined surface. Mounting holes (not shown) are also provided in the cornice attachment 1 for bolting to purlins 5.
As shown in fig. 3, the middle cover plate 2 is a rectangular plate, at least two through holes 21 are provided on the middle cover plate 2, and the number of the through holes 21 on the cover plate is the same as that of the strip holes 11, and two through holes are also used in this example.
The locking connection unit 3 comprises a bolt column and a nut, wherein the upper half part of a column body of the bolt column is a smooth surface, and the lower half part of the column body of the bolt column is a threaded structure. When the sliding device is installed, the bolt columns sequentially penetrate through the roof panel 4, the through hole 21 and the elongated hole 11 from top to bottom, so that the threaded part is connected with the nut, and the smooth surface is in contact with the roof panel 4, the through hole 21 and the elongated hole 11. Thereby the roof panel 4, the intermediate deck plate 1 and the cornice attachment 2 are secured to each other.
The working principle of the embodiment is as follows: when roof boarding 4 takes place expend with heat and contract with cold, roof boarding 4 drives middle apron 2 and slides on eaves mouth connecting piece 1, makes the bolt column remove in rectangular hole 11 simultaneously, provides the space for roof boarding 4's flexible. Be equipped with n type edge 12 on eaves mouth connecting piece 1 to n type edge 12 is towards the square that roof boarding 4 both sides extended, and consequently middle apron 2 when removing, can be blocked by n type edge 12, thereby carries out certain spacing to the sliding position of middle apron 2, prevents that it from taking place to drop, has the effect of buffering moreover.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
