The role of the steel frame greenhouse fitting sink has the following three points: It is not suitable to use small factories to produce cement with unstable strength for the construction of the gutter of the pouring house, and the cement must be sampled and tested before the cement is used, and the construction can be carried out after passing the test; initiating the hot rolling of the gutter reinforcement For smooth round steel bars, cold-rolled ribbed steel bars should be avoided as much as possible, and the steel bars must be certified for sampling test and can be used after passing the test.
The temperature is appropriate on the plan. The roof gutter should be poured and smashed as soon as possible, so that it is bright without leaving the joints, or the gap joints are left at the shrinkage joints of the gutter. It must be determined according to the concrete water-cement ratio plan, and the water-cement ratio cannot be increased. The concrete needs to be meticulous, and the steel frame greenhouse fittings are planned, and the anchoring length must be fixed; the steel frame greenhouse fittings should be carefully guarded, and people should not step on the construction during the construction, and the concrete must be reserved during the construction.
The end of the drive steel pipe that is installed with the new type of film roll in the greenhouse is cut by about 150mm, and there must be no bending or twisting. Connect the drive shaft joint and the drive steel pipe with an M8 jack wire. The overlapping length between the telescopic rod (outer) and the telescopic rod (inner) of the new film reel is not less than 200mm. The telescopic rod (inner) of the new film reel is connected with the fixed pipe of the steel pipe by a telescopic pipe fixing clamp. It is advisable that the climbing steel pipe and the driving steel pipe of the new type film coiler motor are at right angles.
