Construction steel prop nut china

The anchor bolts are generally made of Q235 steel, which is light round. The strength of the rebar (Q345) is large, and the thread of the nut is not easy to be round. For light round anchor bolts, the buried depth is generally 25 times its diameter, and then a 90 degree hook of about 120 mm length is made.

If the bolt has a large diameter (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, you can make a big head (but there are certain requirements). Both the buried depth and the hook are used for the friction between the bolt and the foundation, so that the bolt is not pulled out and destroyed.

(1)Strengthen the management of screw removal, prevent the deformation of the screw, and affect the recycling and reuse of the screw.

(2)Strengthen the management of the mold release agent, and pay attention to not let the release agent flow into the drainage ditch and rivers to avoid polluting the water quality.

(3)When tapping the taper rubber plug, the operator needs to wear a protective mask.

Construction steel prop nut china|casting brilliant, wall-to-wall screws, used for pulling between the inner and outer formwork of the wall formwork, bearing the side pressure of the concrete and other loads, ensuring that the spacing between the inner and outer formwork can meet the design requirements, and also the template The fulcrum of the support structure and the arrangement of the through-wall screws have a great influence on the integrity, rigidity and strength of the formwork structure.

Since there are many stones and steel bars in the concrete, and the water stop screw is basically made of plastic and rubber, if it is improperly constructed, it is easily damaged and gradually enlarged, so that the water stopping effect is affected.

After the actual construction experience, it is concluded that for the water stop screw, it can not be exposed to the sun for a long time, rain, and contact with highly polluting chemicals to avoid damage to the device.

Of course, this kind of quotation only refers to the quotation of the water stop screw itself. It does not include the quotation and shipping cost of the nut, etc. Therefore, in the time of accounting, all aspects should be considered, and the occurrence of the over-standard condition should be minimized.
