Problems solved by technology

[0005] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to provide a metal roof structure with smoke exhaust function to solve the problems existing in the current technology that the roof of public places has no smoke exhaust and ventilation function, the roof construction is difficult, and the thermal expansion of the roof Cracks and corrosion will appear at the cold-shrink button, which will lead to roof leakage. In rainy weather, the drainage capacity of the roof gutter is poor, and the roof needs to be repaired frequently, which increases the maintenance cost.

Embodiment 1

[0049] Please also refer to Figure 1 to Figure 5 Now, a metal roof structure with smoke exhaust function provided by the present invention will be described. This kind of metal roof structure with smoke exhaust function includes a sawtooth beam frame 1, a roof structure 2, a skylight 3 and a drainage ditch 4, wherein the sawtooth beam frame 1 is placed on the roof of the building and fixed on the building Above, the roof structure 2 is fixed on the top of the zigzag beam frame 1, the skylight 3 is installed and inlaid on the roof structure 2, and the drainage ditch 4 is fixed at the lower end of the zigzag beam frame 1 to connect the adjacent roof structure 2. The metal roof structure with smoke exhaust function has no gaps in the overall connection, and has good water and air tightness. Due to the installation of skylights on the roof structure, the roof has the function of smoke exhaust and ventilation. Multiple skylights 3 form air intake windows and air outlet windows. E...

Embodiment 2

[0052] As a specific implementation of the embodiments of the present invention, please refer to Figure 1 to Figure 5 , the metal roof structure with smoke exhaust function provided by this embodiment is basically the same as that of Embodiment 1, the difference is that the zigzag beam frame 1 is composed of a plurality of right-angled triangle beam frames, and the adjacent right-angled triangles The bottom ends of the beam frames are connected with beams; the roof facade structure layer 21 is arranged on the vertical surface of the right-angled triangular beam frame, and the roof facade structure layer 21 is provided with a skylight 3; the roof surface structure layer 22 is arranged on On the slope of the right-angled triangular beam frame; the roof ridge structure layer 23 is arranged on the top of the right-angled triangular beam frame for connecting the roof surface structure layer 22 and the roof façade structure layer 21 .

[0053] Specifically, the zigzag beam frame 1 ...

Embodiment 3

[0064] As a specific implementation of the embodiments of the present invention, please refer to Figure 1 to Figure 6 , the present invention also provides a metal roof surface seam welding construction process, characterized in that: the construction process includes the following steps:

[0065] S1: According to the requirements of the construction drawings, produce roof tiles 5 that meet the installation size, install zigzag beams 1, complete the main body installation, and perform horizontal and vertical verification;

[0066] S2: The steel plate 8 is laid on the zigzag beam frame 1, and the screws on the steel plate 8 are parallel to the purlin 9 in the direction of the roof ridge. direction, a noise reduction layer 11 is laid on the steel plate 8, and a supporting layer 12 and a waterproof layer 13 are laid on the noise reduction layer 11;

[0067] S3: Fix the first row of sliding combined brackets 28 on the sub-purlins 6 with screws and sealing rings, lay the insulati...

Abstract

The invention provides a metal roof structure with a smoke exhaust function, and belongs to the technical field of roof structures. The metal roof structure with the smoke exhaust function comprises azigzag beam frame, roof structure bodies, skylights and drainage ditches, wherein the roof structure bodies are arranged at the top end of the zigzag beam frame, the skylights are arranged on the roof structure bodies, and the drainage ditches are formed in the bottom end of the zigzag beam frame and used for connecting the adjacent roof structure bodies. According to the metal roof structure with the smoke exhaust function, the skylights have the smoke exhaust and ventilation functions, so that the metal roof has good water tightness and air tightness; and through the multiple drainage ditches, the drainage performance of the roof is enhanced, so that the maintenance frequency is reduced, and then the maintenance cost is reduced. The invention further provides a metal roof board edge holding-on welding construction process.

Description

technical field [0001] The invention belongs to the technical field of roof structures, and more specifically relates to a metal roof structure with smoke exhaust function and an overlock welding method. Background technique [0002] With the development of society, the shape of the roof structure is diversified. The roof structure needs to solve the problems of waterproof, heat preservation, heat insulation, noise reduction, drainage and fire prevention, so as to ensure the strength, rigidity and overall space stability of the roof components. [0003] At present, large shopping malls and large national buildings have large roof areas and are mostly densely populated places. The requirements for the reliability of the roof structure against wind, rain and damage are very high. Smoke exhaust ventilation function, smoke exhaust ventilation in public buildings is very important. It is difficult to control the quality of aluminum-magnesium-manganese plate metal roofs, human fac...
