Problems solved by technology

[0002] With the continuous expansion of the construction scale of industrial buildings, metal sandwich panels, as a green building material, excellent thermal insulation performance, convenient installation and many other advantages, are more and more widely used in the roof system of industrial plants; Due to the limitation of core board production technology, self-tapping screws are still used in engineering practice to connect to roof purlins. The internal stress generated by thermal expansion and contraction under the action of temperature in the length direction of the board will accumulate, which will easily cause self-tapping screws The hole expands, causing water leaks, and over time, the screws are easily sheared, rendering the entire roof system useless

Embodiment Construction

[0024] In order to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the present invention is not limited to the following embodiments, refer to Figure 1-9 .

[0025] refer to figure 1 , when the temperature of the metal sandwich panel changes, or when the temperature of the main indoor structure changes, the metal sandwich panel 113 will undergo a physical reaction of thermal expansion and contraction relative to the roof purlins 116 of the main structure; when the cornice is used for fixing, When the sliding support 101 is adopted for other positions, the metal sandwich panel 113 can be freely deformed to release the temperature stress regardless of thermal expansion or cold contraction, which greatly avoids the failure of the roof system accessories and thus the failure of the roof system , the upward arrow in the figure indicates ...

Abstract

The invention discloses a slidable type metal sandwich board roof system and belongs to the technical field of industrial building metal roof systems. The slidable type metal sandwich board roof system comprises roof purlins and metal sandwich boards. Discontinuous Z-shaped secondary purlins parallel to the roof purlins are fixed to the roof purlins. The cornice positions where the adjacent metal sandwich boards are located are fixedly connected with the roof purlins through the Z-shaped secondary purlins, and the non-cornice positions where the adjacent metal sandwich boards are located are fixedly connected with the roof purlins through a sliding support. By adopting the metal surface sandwich board sliding support, the problems of eyehole expanding and water leakage, caused by heat expansion and cold contraction, of the metal surface sandwich boards, shearing of screws and efficacy losing of the roof system are solved, the situation that the metal surface sandwich boards as excellent roof enclosure system materials are widely applied to industrial building roofs is possible, and the assembly process of the industrial building metal sandwich board roof enclosure system is further promoted.

Description

technical field [0001] The invention relates to a slidable metal sandwich panel roof system, which belongs to the technical field of metal roof systems for industrial buildings. Background technique [0002] With the continuous expansion of the construction scale of industrial buildings, metal sandwich panels, as a kind of green building materials, excellent thermal insulation performance, convenient installation and many other advantages, are more and more widely used in the roof system of industrial plants; Due to the limitations of the production technology of the core board, self-tapping screws are still used in engineering practice to connect to the roof purlins. The internal stress generated by thermal expansion and contraction under the action of temperature in the length direction of the board will accumulate, which will easily cause the self-tapping screws to be damaged. The holes expand, causing water leaks, and over time, the screws can be easily sheared, renderin...
