scaffolding Tools scaffold safety operation

Mobile scaffolding accessories often used in engineering, so we must accessories for mobile scaffold technology fully grasp. Jack scaffold (the jack stand): Category A, B, C 3, influenza A jack stand for parts of the window wall panel construction; B no wall plate jack planes for the construction site; hepatitis C jack frame (also known as hanging scaffold) for the construction site with no windows. The safe operation of jack stand points:

(1) jack allows most of the load frame shall not more than 1176 cattle / per square meter, the scaffolding is strictly prohibited stacking of materials, personnel shall not stay focused.

(2) jack scaffolding board shelves next two steps must be covered, paved, firmly fixed. Ceiling when the next step is not hanging over the level of construction safety net. Two steps must be set down two columns of body, head close link established safety net, lateral horizontal bar spacing is appropriate to 0.5-1 meters.

(3) jack upgrade or landing aircraft, use of tower cranes and other lifting appliances, lifting rings must be cards, and forbids any person standing on the shelf with the shelf down.

(4) jack stand shall not exceed the building of two bays, up to no more than 8 meters in width shall not exceed 1 meter. Jack steel rack assembly, the pole spacing not greater than 2 meters, large and small surface shall be located oblique support; welding jack stands, setting borders for the pole, its pole spacing of not more than 2.5 meters, Omo To set up scissors.

(5) Raise the jack stand outside to access network, a height of 1 meter above the layer of construction operations, to dltunxig cwtquyg be set up scissors and top to bottom with a dense mesh safety net to seal the offal to be sealed safety net fastened. Adjacent jack stand should be in the same plane, the interface should be closed tightly.

(6) Alpha-jack planes do not bar should be greater than 10 cm × 10 cm high wooden sides. Do not bar the window up and down to do the mouth, the length of each side of the window to grow 200 mm, up and down the pole and do not bar application of the connection bar Twill pieces; hepatitis C socket rack (hanging rack) the tie rod ends trapezoidal screw threads should be deducted, with the double nut lock securely.

(7) jack rack installation order: alpha-socket rack should be "Do not after the first pick," "hang up after the demolition" (that is, during installation, you should not do a good bar, then put off the clasp; in removed, clasp should be hung, not torn down after the bar.) Hepatitis C jack stand should be installed aluminum beam when the first nut, then put off the clasp; in the removal, the clasp should be hung, then removed the nut.

(8) is the place reinforced concrete wall structure, and its strength should be 70% or more, to install the jack stand.

(9) jack planes must be inspected after installation and acceptance, qualified signatures to use.
