Maintenance of steel structure grid

The maintenance of steel structure grid products is related to the construction quality of later projects, so appropriate protection measures should be taken before, during and after the construction.

        The application of the steel structure grid manufacturing plant in the contemporary engineering construction should be very common, and the different structure and application steps of the steel structure grid also give us different application experience. Next, we need to pay attention to what problems should be paid attention to in the application process of the steel structure grid.

        In the case of steel structure grid, it must be noted that the lifting objects cannot be placed on the steel structure grid. If it is required to have a roof, the construction should be carried out at a distance from the steel structure grid. If it is not enough, it should be immediately pressed on the steel structure grid, and the dirt does not have to rotate on the steel structure grid. 

        Secondly, if it is the stainless steel plate steel structure grid for outdoor application, it is to carry out some maintenance work for the products as far as possible. Otherwise, in the external acid-base etching, it will accelerate the embrittlement of the stainless steel plate, which will cause great harm to the service life of the network speed, and produce poor application effect for all.

        Secondly, after the application of the steel structure grid, we need to pay attention to the maintenance and repair of every period of time, and immediately carry out the re maintenance of some not so good steel structure grid, especially some steel structure grid with long service life, but also should reduce the frequency of maintenance to ensure the safety application of all natural environment

3.1.Protection measures before construction

        Steel structure grid manufacturer

        3.1.1.The steel structure grid frame arriving at the scene of transportation must have product certificate or product quality maintenance book, so as to ensure product quality.It should be noted that effective measures should also be taken for the transportation process to copy the supporting points of the steel structure grid frame and prevent the product deformation due to vibration.

        3.1.2.For small and medium-sized products that are easy to store, they should be put in the warehouse immediately and be left idle.In addition, various products shall be classified, sorted and stored.

        3.2 Protection measures during construction

        3.2.1.Each connection point shall be removed from rust before painting.

        3.2.2.In the process of electric welding, drag plate should be used to avoid sparks splashing and damaging the cable.Before the roof truss is not closed, the cable shall be wrapped with woven cloth to avoid precipitation and rust.

        3.3 Protection measures after construction

        3.3.1.The products after construction should also be maintained in many aspects. It means to ensure that the products will not be damaged before the project acceptance. Therefore, it is necessary to pay close attention to the harmony with other construction units and enterprises in the construction and urge relevant enterprises to pay attention to the maintenance.

        3.3.2.Prior to project acceptance, on-site inspection shall be promoted to avoid product damage.If there is any, we should take effective measures to save in many aspects in time until the product quality standard is achieved.

        3.4 Implementation Countermeasures of civilized construction

        During the construction of the project, detailed protective measures for the processing of finished products and semi-finished products shall be formulated for the manufacturing, transportation, assembly, hoisting and mechanical and electrical engineering to avoid the deformation of steel roof truss and the damage of surface paint. The enterprise or the person who neglects all tasks will bring adverse harm to the smooth progress of the project. Therefore, the following protective measures for finished products shall be formulated.

        3.4.1.Avoid deformation

        In the process of transportation and stacking, the steel structure grid shall be designed with special jig.The setting of idle points for lifting and stacking during shipment and lifting shall be determined according to the calculation.

        In the process of transportation, shipment, stacking, assembly and hoisting, impact and impact shall be avoided to cause partial deformation and endanger the quality of steel structure grid.

        3.4.2.It is forbidden to cut or weld at will

        In the process of construction, enterprises or individuals shall not cut or weld at will.When it is necessary to cut and weld the steel structure grid, the reason and plan of cutting and welding shall be clearly put forward and implemented after being approved by the construction unit or planning institute.

        3.4.3.Avoid paint damage

        In the process of transportation, shipment, stacking, assembly and installation, all steel grid structures shall be in light posture.Sponge pad shall be added to idle point and binding point.

        After the steel roof truss is installed in place, the mechanical and electrical engineering and roof installation enterprises shall pay attention to the maintenance of the cross construction position in the cross construction, and shall not knock the components randomly on average.Hot work is strictly prohibited on the spot.
