The project performance is all over the country, and the perfect project quality has been widely praised by customers.

In recent years, membrane structure buildings have been widely used in garden landscape sketches, factory modeling, stadiums, gas stations, highway toll stations, airports, railway stations, and parking lots due to their unique artistic qualities, beautiful shapes, and strong modern flavor. , Commercial street, exhibition center, landmark building sketches, community landscape, building entrance, pedestrian street, etc. It is foreseeable that as the membrane structure building will be understood and accepted by more people, it will have a broader development prospect and fully meet the rapid development of the 21st century Chinese society and economy people's continuous pursuit of beauty.

Jiangsu Huahai Steel Structure Co., Ltd. "survive by quality, win by development at parity"! Interested parties contact us, we will serve you wholeheartedly! Welcome customers to come to consult and negotiate!



Tension film installation

1. The installation of stretched membrane includes three parts: membrane body opening, joint fixing and stretch forming.

2. During installation, a climbing safety net should be installed on the membrane surface, and the staff must wear safety belts. During the installation process, the staff should wear soft-soled shoes when walking on the membrane surface and should not wear hard objects such as keys.

3. The installation should be carried out when the wind is not greater than level 4. During the installation process, adequate attention should be paid to the wind speed and direction to avoid the appearance of vibration.

4. The appearance of rainwater accumulation should not occur during installation. Together, the interruption and continuity of the project should be decided according to the degree of rainfall. No useful maintenance measures,

5. When tensioning, determine the sequence and value of tension in batches, control the speed of tension, and determine the value of overtension according to the characteristics of the data.

6. When the next process or adjacent project starts construction, it is necessary to adopt maintenance measures to avoid damage to the tensioned membrane that has been completed. It is strictly forbidden to do welding and cutting work within 2m of the membrane material.

7. It is necessary to maintain the product during the auxiliary installation process of the membrane body, and the membrane surface should not be damaged. It is necessary to provide an isolation layer between the membrane surface supporting structures.

8. Before the membrane surface is opened, the fastened splints should be installed first. The spacing of the splints should not be greater than 2m. According to the span of the tensioned membrane, adjust the spacing between the centers of the splints. The bolts and nuts of the splint must be tightened in place.

9. The installation of spine cords and valley cords should be carried out according to the design requirements of the construction organization. In the installation process, temporary ridge and valley pressure ropes should be used before the installation of the spine and valley cables to avoid excessive shaking of the unfinished membrane structure under wind loads.

10. The assembling of the notochord and valley cables and their anchor heads must be strictly implemented in accordance with the technical specifications, and the notochord and valley cables should be stretched in place. , Do not touch directly.



Tension film repair and maintenance

1. The maintenance and repair of the tensioned film shall be provided by the contractor in conjunction with the data supplier, the production unit, and the planning unit to provide the maintenance and repair manual, and the maintenance and repair work shall be entrusted to be performed exclusively.

2. The maintenance and repair shall be carried out in accordance with the contractor’s maintenance manual, and the contractor shall clarify and provide guidance to the owner or the handling party regarding his needs.

3. The party responsible for repairing must keep the maintenance plan, repair records, repair reports, and revision records of the repair company's professional team.
4. All fasteners used in the project, such as bolts, rigging, anchors, etc., must not be rolled at will. When the project is completed 6 months after the completion of the project, its operating conditions should be checked, and if there is looseness, it should be tightened and reinforced.
5. Cleaning should be carried out according to rules. Prevent the cornice from being blocked and maintain the roof drainage system.

6. Professional management personnel should check and clean up the roof before the dry season and winter every year to avoid loosening of waterproof nodes, water falling, gutters, and unblocking.

7. According to the effective use of the membrane data, the pre-tension status, all or single working years should be replaced in time.

8. All the maintenance items of the building should include the shape, deformation, partial folds, cracks and fractures of the membrane surface.
