A plurality of steel bars are preset in the circumferential direction at the bottom of the top member 33. One end of the steel bars extends out of the bottom of the top member 33 as a reinforcing rod 6. The number of reinforcing rods 6 in this embodiment is the same as the total number of the inclined main beam 32 and the inclined supporting beam 34, which is twelve. The inclined main beam 32 and the inclined supporting beam 34 are provided with a reinforcing groove 7 corresponding to the reinforcing rod 6 at one end of the top member 33. When the inclined main beam 32 and the inclined supporting beam 34 are fixed to each other with the top member 33, the reinforcing rod 6 extends out of one end of the top member 33 and is embedded in the reinforcing groove 7. A plurality of mounting rods 8 are evenly arranged on the outer surface of the top member 33. The mounting rods 8 are steel sections preset in the top member 33 when the top member 33 is cast. In the embodiment, six mounting rods 8 are provided, and a plurality of covering plates 9 are installed on the outer surface of the top member 33. Six covering plates 9 are provided, and the two ends of the covering plates 9 in the width direction are respectively fixedly installed on two adjacent mounting rods 8. The six covering plates 9 are connected end to end through the mounting rods 8 and covered on the outside of the top member 33. The covering plates 9 are sheet-like aluminum-magnesium-manganese alloy plates, which are fixedly installed on the mounting rods 8 by welding or clamping. The covering plate 9 is away from the top of the top member 33 and is covered on the outside of the sealing plate 4. The sealing plate 4 is provided to reduce the probability of rainwater infiltrating from the connection between the top member 33 and the inclined main beam 32 and the inclined supporting beam 34; the gap between adjacent covering plates 9 and the gap between adjacent sealing plates 4 are staggered.

[0043] Reference Figure 5-9, the two ends of the inclined main beam 32 in the thickness direction are provided with embedding grooves 10, the sealing plate 4 is a sheet-like aluminum-magnesium-manganese alloy plate, and in this embodiment, six sealing plates 4 are provided, and the two ends of each sealing plate 4 in the width direction are respectively clamped in the embedding grooves 10 of the adjacent inclined main beams 32 by deformation; the bottom of the embedding groove 10 is slidably provided with an insertion rod 11, and a plurality of insertion rods 11 are evenly provided along the length direction of the inclined main beam 32, and the insertion rod 11 provided at the inclined main beam 32 near the top member 33 is inserted into the reinforcing rod 6 by sliding; the side wall of the embedding groove 10 is slidably provided with a top rod 12, and the top rod 12 A linkage rod 13 is provided between the rod 11 and the insertion rod 11; the linkage rod 13 is an L-shaped rod, one end of the linkage rod 13 in the length direction is fixed on the insertion rod 11, and a receiving groove 14 is provided at the linkage rod 13 away from the insertion rod 11, one end of the ejector rod 12 is received in the receiving groove 14, and a lifting block 19 is provided at the end of the receiving groove 14 away from the connecting insertion rod 11, and the lifting block 19 is an arc block. When the insertion rod 11 slides toward the bottom of the embedded groove 10 until it is flush with the bottom of the embedded groove 10, the lifting block 19 abuts against the ejector rod 12 and ejects the ejector rod 12 out of the side wall of the embedded groove 10, and the linkage rod A spring 15 is arranged between 13 and the inclined main beam 32, and the elastic force of the spring 15 drives the linkage rod 13 to slide away from the bottom of the embedded groove 10. The setting of the spring 15 makes the insertion rod 11 extend into the embedded groove 10 under normal conditions, and the push rod 12 is provided with a wedge-shaped surface at one end facing the opening of the embedded groove 10. The push rod 12 is inserted into the embedded groove 10 and an anti-slip block is fixed at one end thereof. The anti-slip block can limit the push rod 12 from being separated from the embedded groove 10. The setting of the wedge-shaped surface can reduce the probability that the push rod 12 blocks the sealing plate 4 from being inserted into the embedded groove 10. When the end of the sealing plate 4 in the width direction is deformed and inserted into the embedded groove 10, the sealing plate 4 is inserted into the embedded groove 10. When in the groove 10, the end of the sealing plate 4 abuts the insertion rod 11 and drives the insertion rod 11 to slide. After the insertion rod 11 slides, the linkage rod 13 drives the push rod 12 to extend out of the side wall of the embedded groove 10. The push rod 12 drives the sealing plate 4 to deform, reinforce the sealing plate 4, and reduce the probability of the sealing plate 4 detaching from the embedded groove 10. In this embodiment, before the sealing plate 4 is inserted into the embedded groove 10, one end of the two sealing plates 4 that need to be fixed in the width direction must be stacked on the inclined main beam 32, and then the two sealing plates 4 are driven to deform and insert into the two embedded grooves 10 of the same inclined main beam 32 at the same time.

The mounting holes 16 are used to penetrate the embedded bolts 2 preset in the mounting grooves 1 on the main building structure. After the embedded bolts 2 penetrate the mounting holes 16, nuts are installed on the embedded bolts 2 for fixing. A circular ring-shaped protrusion 17 is fixed on the steel bottom beam 31 away from the inclined main beam 32. The protrusion 17 is used to be embedded in the mounting groove 1 on the main building structure to play a role in installation and positioning.

When making the steel bottom beam 31, it is necessary to estimate the installation positions of the inclined main beam 32 and the inclined support beam 34 and open the installation holes 16 on the steel bottom beam 31 according to the embedded bolts 2. The top member 33 is cast at the same time, and then the steel bottom beam 31, the inclined main beam 32, the inclined supporting beam 34, the steel waist beam 35 and the top member 33 are assembled into a roof frame 3 by splicing and welding, and a layer of thermal insulation cotton layer 5 is coated on the outside of the frame, and then the sealing plate 4 is installed between the inclined main beams 32.
