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 and 2, the present embodiment provides a heightening type double-layer roof panel structure, which includes a first purline 1, a second purline 2, an outer roof panel 3, an inner roof panel 4, and a heightening member 5. First purlin 1 is laid on the girder on building roof with conventional mounting means parallel, and first purlin 1 can adopt channel-section steel purlin, angle steel purlin, combination channel-section steel purlin, combination Z shaped steel purlin or H shaped steel purlin etc. and the preferred combination Z shaped steel purlin that adopts of this embodiment. The inner roof plate 4 is laid on the first purline 1. A plurality of heightening pieces 5 are installed at the bottom of the second purline 2, and the specific positions and the number of the heightening pieces 5 are distributed according to the stress structure of a building. The second purline 2 is fixed on the roof inner plate 4 through the heightening piece 5, and the roof outer plate 3 is laid on the second purline 2. In this embodiment, second purlin 2 corresponds and is located every first purlin 1 directly over, improves roofing structure's intensity and stability.

As shown in fig. 2 and 3, the height increasing member 5 is an integrally formed metal plate member, and includes a height increasing member top plate 51 and side plates 52 symmetrically located at both sides of the height increasing member top plate 51, and a height increasing member bottom plate 53 is provided at a lower end of the inclined plate. The roof inner panel 4 is provided with longitudinal grooves 41 on the top surface thereof such that two height-increasing member bottom plates 53 of one height-increasing member 5 are fitted into two different longitudinal grooves 41 and fixedly connected to the bottom surfaces of the longitudinal grooves 41 by bolts. Each of the heightening member bottom plates 53 is provided with at least two bolt holes for fixation. The heightening piece top plate 51 is connected with the second purline 2 through bolts. The top plate 51 and the side plate 52 of the heightening part are obliquely connected to form an isosceles trapezoid, so that the installation stability of the heightening part 5 is ensured. In other embodiments, the top plate 51 and the side plate 52 of the heightening part are vertically connected to form a rectangle, so that the structure is more compact, and the manufacturing material cost is reduced.
