Manufacturing process of galvanized screw and the fabrication and installation of galvanized screw

2018-01-01
The manufacture and installation of galvanized screws:
Hot-dip galvanized screw
(1) choose a galvanized screw locking ring (tube) alloy bit the same diameter, the installation of electric drill holes in the wall again, the depth of the hole and the best bolt of the same length, and then went down to the galvanized screw hole, remember; don't twist off the nut, prevent hole drilling comparison deep into the hole and bolt is not good to take.
(2) to tighten the nut 2-3 buckle tight feeling after galvanized bolts without loosening and then unscrew the nut, then fixed objects with holes punched in a fixed alignment bolt mounted on the outside of the shim or spring washer to tighten the nut.
Make a wall hole according to the outer diameter of the tube. If the brick wall is soft, choose the number one bit properly. The expansion pipe part should be all into the wall, as long as the thread part is long enough, the deeper and stronger the casing part is.
(3) galvanized screws installer specifically for the installation of galvanized screw structure in special environment and design, six horns including internal interface adapter in galvanized screws, which is characterized in that also includes at least one section tube, the upper end of the tube is fixed to the six horns; the upper part of the tube body is arranged impact drill installation a. It can be tied in the air, and quickly and quickly tighten the installation of galvanized screw or expansion hanger, which is 3-6 meters from the ground.

Construction attention
1, the depth of drilling: the length of expansion pipe is introduced in related data, but in my specific construction, it is found that this depth is not enough, and it may be related to residual debris in the hole, so you'd better be 5 mm deeper than the length of the expansion pipe. As long as you are greater than or equal to the length of the expansion pipe, the length of the expansion bolt at the ground is equal to or less than the length of the expansion pipe.
2. The requirement of the expansion bolt to the ground is, of course, the harder the better. It also depends on the force that you need to be fixed. The strength of the C13-15 is five times as strong as that in the brick body.
3. After a M6/8/10/12 expansion bolt correctly installed in the soil, the most unideal maximum static force is 510 kilograms, respectively. (notice, the vibration will make the bolt loose)
