The gap between the main steel structure beam 1 and the bottom plate 6 can be changed by adjusting the connector 3. When in use, the connector 3 can serve as a supporting surface for the bottom plate 6 to bear the weight of other structural layers, and can also adjust the gap between the bottom plate 6 and the main steel structure beam 1, thereby changing the installation height of the bottom plate 6, so that the connection line between the bottom plate 6 and the main steel structure beam 1 is more beautiful, more stable, safer and less likely to shake, thereby improving the overall wind resistance performance.

[0021] Preferably, Figure 3 As shown, the connecting member 3 includes a supporting body 31 and a first supporting plate 32 and a second supporting plate 33 arranged on both sides of the supporting body 31. The ends of the first supporting plate 32 and the second supporting plate 33 away from the supporting body 31 are connected to the main steel structure beam 1.

In this embodiment, the first support plate 32, the second support plate 33 and the support body 31 are integrally formed, and the three are assembled into a support member with an opening, and the opening faces the main steel structure beam 1, which is more convenient to find the bottom surface position of the bottom plate 6, so that the bottom surface lines of the bottom plate 6 are smooth and beautiful.

[0024] Preferably, the base plate 6 is connected to the support body 31 via a fastener 11 .

[0025] Preferably, Figure 2 As shown, the support column 2 connects the main purlin 4 and the roof panel 10, and the main purlins 4 are connected by the secondary purlins 5, and the secondary purlins 5 are in contact with the bottom plate 6. In this embodiment, the main purlins 4 are installed with the roof panel aluminum alloy fixing seat 13 for installing the roof panel 10, and the secondary purlins 5 are connected between the main purlins 4. The bottom surface of the secondary purlin 5 is pressed against the bottom plate 6 to resist the upward wind load borne by the bottom plate 6. At the same time, the secondary purlin 5 is used to fix the rock wool lining nails 12 to reinforce the structural layers such as the insulation layer 7 and the waterproof layer 8, so that the connection is more stable.

[0026] Preferably, the number of the supporting columns 2 is at least two, and the plurality of supporting columns 2 are arranged in parallel and used to support the main purlins 4 .

[0030] Preferably, the main purlin 4 is connected to the roof panel 10 via a fixing seat 13 .

[0031] Embodiment 1:

[0032] The finished surface of the steel structure was re-measured and a three-dimensional model of the metal roof was established.

[0033] The connecting member 3 is a U-shaped folding member. The first support plate 32, the support body 31 and the second support plate 33 are bent in sequence to form a folding member with an opening. The bottom surface of the base plate 6 can be leveled and adjusted by adjusting the height of the support plates on both sides and adjusting the angle between the support plates on both sides and the support body 31, so that the top surface lines of the steel structure are smooth. At the same time, the support body 31 can serve as a supporting surface for the base plate 6, which is more stable.

[0034] The connector 3 is welded to the upper surface of the main steel structure beam 1, the opening of the connector 3 faces the main steel structure beam 1, and the bottom plate 6 is fixed to the supporting body 31 by fasteners (stainless steel self-tapping screws) 11. The bottom plate 6 is used to bear the weight of the thermal insulation layer 7, waterproof layer 8, sound insulation layer and other structural layers of the metal roof.

[0035] The support column 2 is a U-shaped purlin column, which is welded parallel to the main steel structure beam 1 at a certain interval, and is used to support the main purlin 4 of the roof. The main purlin 4 is inserted into the U-shaped opening of the support column 2, and the elevation of the main purlin 4 can be adjusted by changing the height of the groove. The roof panel fixing seat 13 is installed on the main purlin 4 for installing the roof panel 10. The secondary purlin 5 is connected between the main purlins 4, and the bottom surface of the main purlin 4 is tightly pressed against the bottom plate 6 to resist the upward wind load borne by the bottom plate 6. At the same time, the secondary purlin 5 is used to fix the rock wool lining nails 12 to reinforce the filled insulation layer 7, waterproof layer 8 and sound insulation layer 9 to make the structure more solid.

[0036] The supporting columns 2, the main purlins 4 and the secondary purlins 5 and other components are located between the bottom plate 6 and the roof panel 10 and are in an "invisible" state, so that the formed roof is neat and beautiful.

The connector 3 must be processed into a form of unequal height or a U-shaped folded piece of corresponding height according to the actual inclination of the steel structure main beam on site, so as to adjust the structural surface of the main steel structure. Only by adjusting the structural surface of the main beam can the bottom plate perfectly fit the steel beam and thus be stably installed.

[0049] (2) A hole is opened in the connecting member 3, and a hole is opened at the junction of the connecting member 3 and the supporting column 2 for the supporting column 2 to pass through.

[0050] (3) Use a crane to hoist the connector 3 to the corresponding position of the roof construction, and then weld it to the main steel structure beam (i.e., the main steel structure beam 1).

[0051] (4) After welding, clean the welding slag and remove rust from the weld.

[0052] 5. Install the base plate 6

[0053] (1) The corrugated steel sheet is pressed by pressing equipment, with a wave height of 75mm and a wave distance of 200mm. The thickness of the corrugated steel sheet in this project is 1.2mm-1.5mm (1.2mm is used for spans less than or equal to 4m, and 1.5mm is used for spans greater than 4m). The specific thickness is determined by calculation according to the weight of the roof insulation layer and wind load.

[0054] (2) Install the base plate 6 and fix both ends of the base plate 6 to the connecting piece 3 using stainless steel self-tapping screws 11.

[0055] 6. Install the main purlin of the metal roof 4

[0056] (1) The main purlin 4 is installed in the notch of the support column 2. The height can be adjusted in the notch. After the elevation adjustment is completed, it is temporarily fixed by spot welding or bolting.

[0057] (2) Review the spatial coordinates of the roof purlin installation forming surface to ensure the three-dimensional modeling accuracy of the metal roof.

[0058] (3) After re-measurement and adjustment, the main purlin 4 is welded to the support column 2.

[0059] (4) Install the secondary purlin 5 of the metal roof. The secondary purlin 5 is close to the upper surface of the bottom plate 6, and the two ends are connected to the main purlin 4.

[0060] 7. Install the thermal insulation layer 7, waterproof layer 8, vapor barrier layer, sound insulation layer 9 and other structural layers.

[0061] 8. Install the standing seam roof panel fixing support (aluminum alloy fixing seat) 13 on the main purlin 4, and install the standing seam fan-shaped roof panel (this project uses 0.9mm aluminum-magnesium-manganese roof panel).
