[0005] In order to solve the above problems, the technical solution proposed by the utility model is: a combined assembled and slidable structure for roof openings, including a precast base, which is arranged at the opening of the roof outer panel; secondary purlins are installed at the positions without purlins around the roof opening, and an additional C-shaped purlin is arranged under the back panel; square pipe slide bars are fixedly installed at the downslope direction and the lower opening of the roof opening, and the roof opening is tightly connected with the roof outer panel through the square pipe slide bars; a peak inner plug is installed below the roof opening; the precast base is placed on the cross-shaped frame, and a butyl tape is laid at the positions of the roof opening around the base; a peak outer cover plate and a water dividing plate are installed at the joint position between the precast base and the roof outer panel through self-tapping screws.

[0006] As an improvement, a butyl tape is laid at the junction of the three square pipe slide bars during the installation of the back panel.

[0007] As an improvement, the precast base, the square pipe slide bars and the roof outer panel are respectively fixed through self-tapping screws and fixing buckles.

[0008] As an improvement, the periphery of the water dividing plate is fully coated with weather-resistant glue.

[0009] As an improvement, the precast base adopts a precast modular design.

[0010] Advantages of the present utility model:

[0011] By adding square tube slide bars at the connection between the precast base and the roof outer panel, the problem that the bases of traditional ventilators, daylighting skylights, fans, etc. cannot slide is effectively solved, avoiding the formation of "sliding islands" on the roof, releasing temperature stress, reducing the potential for water leakage. At the same time, the construction combines the factory and on-site methods, which is beneficial to improving the project quality, construction period, cost and later maintenance, and promotes the progress of the installation technology of the metal roof system.

[0017] The present utility model will be further described below with reference to the drawings.

[0018] According to Figures 1-4 As shown: The present utility model provides a combined prefabricated and slidable structure for roof openings, including a precast base 1, and the precast base 1 is arranged at the opening of the roof outer panel 2; secondary purlins 3 are installed at the positions without purlins around the roof opening, and an additional C-shaped purlin is arranged under the back plate 4; square tube slide bars 5 are fixedly installed at the downslope direction and the lower opening of the roof opening, and the roof opening is tightly connected to the roof outer panel 2 through the square tube slide bars 5; an inner plug 7 at the wave crest is installed below the roof opening; the precast base 1 is placed on the cross-shaped frame, and a butyl tape 6 is laid at the positions of the roof opening around the base; the wave crest outer cover plate 11 and the water diversion plate 12 are installed at the joint position between the precast base 1 and the roof outer panel 2 through self-tapping screws 9.

[0019] The roof outer panel 2 and the prefabricated base 1 are fixed by adding square tube slides 5, which can ensure that there is no connection with the purlins, and can ensure that the roof can slide along the slope without overlap and can slide as a whole, avoiding the formation of a "sliding island" on the roof, releasing temperature stress, and reducing the risk of leakage.

[0020] When the back plate 4 is installed, butyl tape 6 is laid at the junction of the three square tube slides 5. The prefabricated base 1, the square tube slide 5 and the roof outer plate 2 are fixed by self-tapping screws 9 and fixing buckles 8 respectively, which facilitates the assembly and connection of the prefabricated base 1, the roof outer plate 2 and the square tube slide 5.

[0021] The water dividing plate 12 is fully coated with weather-resistant glue 10 on all sides, which can resist the influence of extreme weather such as ultraviolet rays, acid rain, snow, etc., and improve the sealing performance.

[0022] The prefabricated base 1 adopts a prefabricated modular design and is designed according to the effective width of the 360° interlocking roof panel to avoid collision between the two sides of the prefabricated base 1 of the roof opening and the wave crests of the roof outer panel 2, so that water can pass smoothly.

The purlin opening direction is adjusted to the outside of the opening, and the back of the purlin is flush with the edge of the opening, and a reliable connection is formed by using the angle code. In order to ensure the sliding characteristics of the roof system, the roof opening is tightly connected to the roof outer panel 2 only through the square tube slide 5. After the secondary purlin of the roof is installed, a square tube slide 5 is set on the secondary purlin in the slope direction and the lower position, and the outer edge of the square tube slide 5 is flush with the edge of the roof panel. When the back plate 4 is installed, butyl tape 6 is laid on the roof outer panel 2, the secondary rib, and the square tube slide 5, and a wave crest inner plug 7 is installed below the roof outer panel 2 at the opening (above the purlin); the prefabricated base 1 is mainly formed by welding and assembling 2mm~3mm steel plates, and holes are punched at the bottom of the prefabricated base 1, and the hole spacing shall not be greater than 100mm (the base is made in the factory and installed on site). The base is accurately placed on the cross frame, and a butyl tape 6 is laid around the opening position of the roof outer panel 2 around the prefabricated base 1, and the weather-resistant glue 10 is fully spread at the joint between the prefabricated base 1 and the roof outer panel 2; and the peak outer cover plate 11 and the water diversion plate 12 are installed at the joint position between the prefabricated base 1 and the roof outer panel 2, and the weather-resistant glue 10 is fully coated around the water diversion plate 12 to prevent rainwater penetration.
