Further, the support and the purline are fixed through screws.
Furthermore, the cross section of the support is Z-shaped, the support comprises a transverse bottom plate fixedly mounted with the support, a vertical middle plate perpendicular to the transverse bottom edge, and a transverse top plate formed by transversely extending one end of the vertical middle plate, and the vertical middle plate penetrates through the vertical locking seam, so that the transverse top plate is arranged in a wrapping range of the female fastening end of the vertical locking seam roof panel.
Furthermore, the transverse width of the transverse top plate is not more than the transverse width of the female buckle end of the corresponding vertical lock seam roof panel.
Furthermore, the vertical height of the vertical middle plate is not less than the vertical height of the male buckle end of the corresponding vertical locking seam roof panel.
Further, a composite board and a waterproof coiled material are further laid on the light steel roof truss, and the purlines are arranged on the composite board.
Further, the thickness of the waterproof coiled material is 1.2 mm.
Furthermore, glass wool is laid on the light steel roof truss.
Compared with the prior art, the invention has the following advantages:
(1) through setting up the support and stretching into in the vertical lock seam and rather than the interlock fixed, again with support and purlin fixed mounting, both guaranteed the reliability of connecting, avoided vertical lock seam roof boarding to punch the problem that waterproof nature that the installation caused can reduce, simultaneously, also very big made things convenient for vertical lock seam roof boarding's installation.
(2) The support adopts special zigzag, has guaranteed the stability of being connected with vertical overlock roof boarding, can not influence its original waterproof performance, simultaneously, has certain clearance between support and pin thread, the box, also can avoid expend with heat and contract with cold to the influence of junction.
(3) The composite board and the waterproof coiled material are laid on the light steel roof truss, so that each layer of space is further increased between the composite board and the vertical lock seam roof board, and the heat insulation performance of the whole system is improved.
