Modulus ruler for installing metal roof board

Abstract

The invention relates to a modulus ruler for installing a metal roof board. The modulus ruler for installing the metal roof board is used for fixedly installing a connecting support frame of the metal roof board, and comprises a horizontal bottom surface and projected edges positioned at the two sides of the horizontal bottom surface; installing holes are formed in each of two ends of the horizontal bottom surface; positioning limiting sheets are arranged on the installing holes formed in one end; two positioning control mechanisms in corresponding arrangement are arranged at the inner sides of the installing holes formed in the other end; and support frame installing holes are formed between the positioning control mechanisms. Compared with the prior art, the modulus ruler has the advantages that the problem of different technological levels of installing personnel is solved; the absorption effect of hot expansion and cold contraction of a roof system can be achieved; the difficult problem of forced pulling damage of the board on roof purlins due to hot expansion and cold contraction is solved; good economic benefits and social benefits can be achieved; the problem of installing difficulty of industry is solved; and the professionalization level of the industry is improved.

Description

Technical field [0001] The invention relates to the field of building roofs, in particular to a modular ruler for installing metal roof panels. Background technique [0002] At present, the metal roof panels commonly used in construction are mainly divided into the following three forms from the installation method: nailing, buckle and lock seam. The construction speed of nailed roof slabs is slow, and the temperature stress at the nailing joints is concentrated, which is easy to deform and cause leakage; although the fastening roofs are easy to install, sometimes false fastenings occur due to the lack of construction experience of workers. , The snap-fit ​​roof panel has low wind and suction resistance, and its watertight and airtight performance is not ideal. The vertical lock seam roof panel overcomes the problems of the above two roof panels. [0003] Upright lock seam roof refers to that the adjacent panels are interlocked along the longitudinal edge of the panel during inst...

AI Technical Summary

Problems solved by technology

But now the installation personnel in the industry have uneven skills. When installing the brackets, they are crooked and twisted, which causes the brackets on the roof panel to be out of alignment. In this way, the ribs of the installed panels are not straight, which will cause the panels to be unable to expand and contract freely during thermal expansion and contraction. As for the deformation of the roof panel caused by thermal expansion and contraction cannot be eliminated, it often leads to cracking of the roof, distortion of the bracket due to deformation, and water leakage from the roof.
