Embodiment 1

[0028] like figure 1 As shown, this embodiment provides a laterally connected roof bottom plate, including several bottom plates connected in sequence, the bottom plate includes a bottom plate 1 and a supporting rib 1 and a supporting rib 2 respectively disposed at opposite ends of the bottom plate 1 . , the first support rib includes a plate rib and a connecting piece extending outward from the end of the bottom plate 1, the connecting piece and the second supporting rib have a matching downward bending structure, and the two adjacent bottom plates are connected When fixing, the bending structure of the second supporting rib of one of the bottom plates is sleeved into the bending structure of the connecting piece of the other adjacent bottom plate, and then the connecting piece of the two bottom plates and the second supporting rib are connected by the fastener 14. Bend the sides of the structure to fix the two bottom plates. The connection between the two adjacent bottom pl...

Embodiment 2

[0034] On the basis of the above examples, if Figure 4 As shown, this embodiment provides a roof panel system, including the above-mentioned roof base plate, and the top plate 17 arranged above the roof base plate, the adjacent roof plates 17 are connected by locking devices, and the connection between two adjacent roof base plates It is connected with the locking device through the support assembly.

[0035] Wherein, the locking device includes a support keel 19 and a buckle cover 20, the end of the top plate 17 is clamped between the support keel 19 and the buckle cover 20, and the lower end of the support keel 19 is connected with the support assembly; the buckle There is a flange 21 extending outward and obliquely downward at the edge of the cover 20. The support keel 19 is located in the vertical projection of the buckle cover 20, and the support keel 19 and the buckle cover 20 are fixed by bolts to compress the top plate 17. A cap 22 is provided above the buckle cover ...

Abstract

The invention provides a lateral connected roof bottom board. The lateral connected roof bottom board includes a plurality of bottom plates which are successively connected; each bottom plate includesa bottom flat plate and a first supporting rib and a second supporting rib which are arranged on two opposite ends of the bottom flat plate respectively, wherein the first supporting rib includes a plate rib extending from an end of the bottom flat plate to outside and a connection member, the connection member and the second supporting rib have downward bent structures matching each other; the bent structure of the second supporting rib of one bottom plate is sleeved with the bent structure of the connection member of the other adjacent bottom plate, and the connection member and a lateral part of the bent structure of the second supporting rib are connected through a fastening member; the connection members and the lateral parts of the bent structures of the second supporting ribs of the two adjacent bottom plates are fixed through fastening members; water leakage of surfaces of the conventional bottom boards due to nail holes can be prevented, the waterproof performance of the roofbottom board is improved, lap-joint of the bent structures of the two bottom plates can enhance the strength of the connection portions, the tension bearing capacity of the fastening members can be improved under an action of a wind load, and the windproof performance of the roof bottom board can be improved.

Description

technical field [0001] The invention relates to the technical field of metal roofing systems, in particular to a laterally connected roofing bottom plate and a roofing plate system. Background technique [0002] Profiled metal roofing systems are widely used in large-scale projects such as airports, stadiums, convention and exhibition centers, industrial plants, warehouses, railway platform canopies, and railway station roofs because of their light weight, high strength, beautiful appearance, and convenient construction. [0003] At present, the metal roof system mainly has two forms: single-layer metal roof panel system and double-layer metal roof panel system. Standing seam and other forms. For the bottom plate of the double-layer metal roof system with built-in purlins, metal strips or profiled metal plates are often used, and the fixed connection forms of the bottom plate are various. For the double-layer metal roof system with exposed purlins, the profiled metal plate...
