Description

Technical Field

[0001] The invention relates to the technical field of super-long roof panel construction of a factory building, and in particular to a construction method of super-long roof panel of a steel structure factory building. Background Art

[0002] In the construction of metallurgical projects, steel structure workshops are a common main structure, and the enclosure structure is mainly enclosed with colored tiles. The traditional construction method of metal roof panels for traditional large-span steel structure workshops is to transport the processed roof panels to the construction site, use a car crane or manually transport the roof panels to the corresponding position of the roof, and then overlap and install them. However, this construction method is inconvenient, the roof panels are easily deformed and damaged during transportation, and a large number of people are required to overlap the roof panels during installation, which has a long construction period and high construction costs. Summary of the invention

[0003] The embodiment of the present invention provides a method for constructing an ultra-long roof panel of a steel structure factory building, which has the technical effects of shortening the construction period and reducing the construction cost.

[0004] A method for constructing an extra-long roof panel of a steel structure factory building of the present invention comprises the following steps: Step 1: Construction preparation; Before the high-altitude tile press equipment enters the site, the site needs to be leveled and hardened. The roller on the high-altitude tile press should be close to the eaves, and the height should be the same as the eaves to ensure smooth transportation of the roof panels; Step 2: Adjust the parameters of the high-altitude tile press; After the high-altitude tile pressing machine is in place, adjust the forming mold according to the process requirements of the color steel plate to ensure that the metal roofing panel is pressed into a shape that meets the requirements; set the cutting length that meets the requirements. Repair and maintain the machine before starting work, and conduct trial production; Step 3: Install the steel coil raw materials The raw material for producing metal roof panels is coiled plates, which need to be stacked on overhead supports near the tile press, kept ventilated and dry to avoid moisture affecting the surface quality of the coiled plates. The coiled plates are hoisted by a crane and installed on the support roller of the high-altitude tile press. The hoisting device uses a flat polyester sling with a working load of 4t.

[0005] Step 4: Roof panel profile conveying; When starting the high-altitude tile pressing machine, the roller speed must be slow and steady; after the metal plate reaches the designed length, stop pressing and cut the metal plate. The length of the metal plate needs to be slightly longer than the designed length to facilitate the later cutting and adjustment of the plate end; First, process a plate, and check whether the plate ribs and plate surface of the finished product are processed and formed according to the design requirements according to the product quality inspection list, and whether there are scratches on the plate surface. After the first plate meets the requirements, start mass processing of the remaining metal plates; Step 5: Roof panel installation; After the roof panels are transported to the roof, they are lifted by manpower. According to the weight of the roof panels per meter, the construction workers lift them from both sides. To protect the workers' hands from scratches, the construction workers lift them from the bottom of the panels with rubber bands. There are many construction workers involved in lifting the panels, so a dedicated person must be assigned to direct and coordinate them and keep them consistent. The commander uses a tweeter to give commands.

[0006] Furthermore, when trial production of metal roof panels is carried out, the panels are passed through the forming die and observed for abnormal noise, 500mm samples are processed, and rolled according to the requirements of the product quality inspection list to ensure that there are no scratches within the length of the roller, and the parameters of the tile press are repeatedly adjusted until qualified metal panels can be produced.

[0007] Compared with the prior art, the present invention has the following technical effects: The invention solves the problems of complicated traditional installation process, long construction period, high construction cost, easy to cause roof leakage, poor roof integrity, unsightly appearance, etc. The invention is used to install the roof panel, and the mechanical automation installation degree is high, which can improve the construction progress and save costs. DETAILED DESCRIPTION

[0008] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0009] A method for constructing an extra-long metal roof panel of a steel structure factory building comprises the following steps: Step 1: Construction preparation Before the high-altitude tile press equipment enters the site, the site for the equipment should be selected based on the actual situation on site and after consultation with the owner. The site should be leveled and hardened in advance so that the entire bottom of the equipment is evenly stressed after it is in place to ensure that the equipment can run smoothly during operation. The roller should be close to the eaves and the height should be the same as the eaves to ensure smooth transportation of the roof panels.

[0010] Step 2: Adjust the parameters of the high-altitude tile press After the high-altitude tile pressing machine is in place, the forming mold must be adjusted according to the process requirements of the color steel plate to ensure that the metal roofing panel is pressed into the required shape; set the cutting length that meets the requirements. Repair and maintain the machine three days before the start of work, and conduct trial production. The trial production uses the slow-feed mode to make the plate pass through the forming mold and observe whether there is any abnormal noise. Process a sample of about 500mm and roll it into shape according to the requirements of the product quality inspection list to ensure that there are no scratches within the length of the roller. Repeatedly adjust the parameters of the tile pressing machine until qualified metal plates can be produced.

[0011] Step 3: Install the steel coil raw materials The raw material for producing metal roof panels is rolled plates, which need to be stacked at a designated location near the tile press. The rolled plates are stacked on overhead supports to keep them ventilated and dry to avoid moisture affecting the surface quality of the rolled plates. Each rolled plate weighs about 3 tons, and the rolled plates are hoisted by a crane and installed on the support roller of the high-altitude tile press. The hoisting device should use a flat polyester sling with a working load of 4 tons instead of a wire rope to avoid deformation of the plate edge ribs during the hoisting process.

[0012] Step 4: Roof panel profile delivery After placing the coil on the support roller of the aerial tile pressing machine, the hydraulic system is used to support the metal tile pressing system. The chain drives the transmission roller to rotate, so that the metal roof panel is transported on the roller table. The metal roof panel is pressed into a set shape through a forming mold and cut off.

[0013] When starting the high-altitude tile pressing machine, the roller speed must be slow and steady. After the metal plate reaches the designed length, stop pressing and cut the metal plate. The length of the metal plate needs to be slightly longer than the designed length to facilitate the later cutting and adjustment of the plate end. First, process a plate, and check whether the plate ribs and plate surface of the finished product are processed and formed according to the design requirements, whether there are scratches on the plate surface, and whether other aspects meet the requirements according to the product quality inspection list. After the first plate meets the requirements, start mass processing of the remaining metal plates.

[0014] Step 5: Roof panel installation After the roof panels are transported to the roof, they are lifted by manpower. According to the weight of the roof panels per meter, the construction workers lift them from both sides, with a spacing of about 3m. In order to protect the hands of the construction workers from being scratched, the construction workers lift them from the bottom of the panels with rubber bands. There are many construction workers involved in lifting the panels, and they must be commanded and coordinated by a dedicated person to maintain consistency in order to protect the construction workers from being injured. The commanding personnel use a tweeter to command.

[0015] The present invention has the following technical effects: the roof panel is not easy to be damaged or deformed during transportation, and it also has the characteristics of flexible and fast movement of the conveying plate position; the transportation method of this construction technology is not limited by time, site and materials, and the roof panel can be continuously transmitted to the roof, ensuring the continuity of on-site installation; the installation process is simple, reducing the waste of manpower and material resources, with high construction efficiency, safe and reliable operation, and reducing construction costs; the roof has strong integrity, light weight, and good waterproof effect; the present invention solves the problems that the traditional installation process is relatively complicated, the construction period is long, the construction cost is high, and it is easy to cause roof leakage, poor roof integrity, and unsightly. The invention is used to install the roof panel, and the degree of mechanical automation installation is high, which can improve the construction progress and save costs.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
