Embodiment Construction

[0019] Such as figure 1 , 2 , Shown in 3, a kind of PC board roof, mainly is formed by connecting by many PC boards, is provided with expansion joint between adjacent PC boards 1,1, expansion joint bottom is filled with foam board 38, and top is filled with There is a deformable sealant 37, and the sealant 37 seals the expansion joint; below the expansion joint, there is a main keel supporting the PC board 1, 1` and accepting water leakage. The main keel includes a strip-shaped bottom plate 44 arranged under the expansion joint , the bottom plate 44 is vertically spaced above the support plate, the support plate includes an outer support plate 42 and an inner support plate 43, and the top surface of the inner support plate 43 is lower than the top surface of the outer support plate 42. Two of the outer support plates 42 are symmetrically arranged, and two of the inner support plates 43 are also symmetrically arranged. The inner support plate 43 and the outer support plate 42 ...

Abstract

The invention discloses a PC board roof, which is mainly formed by a plurality of PC boards in a connecting way. An expansion joint is arranged between two adjacent PC boards. A key keel supporting the PC boards and taking over leaked water is arranged below the expansion joint. A PC board auxiliary frame is fixed on the bottom surface of each PC board. The PC board auxiliary frame is assembled on the key keel. The PC board auxiliary frame is limited by a limiting piece and can slide in the direction in parallel with the key keel only. Deformable sealant is filled in each expansion joint. Adjacent key keels are connected in a sealing way by adopting connectors. Aiming at the defects that the existing PC board is apt to be expanded and deformed under heating, water leakage is apt to be caused and the sealing is uneasy, the invention provides the PC board roof which has the advantages that large expansion and deformation of the PC board are endured, water leakage is prevented, the assembling is simple and the connection is reasonable.

Description

technical field [0001] The invention relates to a house roof, in particular to a PC board roof. Background technique [0002] PC board is made of polymer engineering plastic polycarbonate (POLYCARBONATE, referred to as PC) as the main raw material, and co-extruded with anti-ultraviolet UV material. PC board has good light transmission, light weight, sound insulation and flame retardant. . It is a good material for building exterior walls and roofs. However, due to the large thermal expansion coefficient of PC boards, there are disadvantages of large expansion, contraction and deformation at different temperatures. If the fixing method of PC boards is unreasonable, it will cause water leakage on the PC board roof. Even the PC board cracked. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a PC board roof that can withstand large expansion and contraction deformation of the PC board, prevent water leakage, and is ...
