Specifications for prong bolts

Steel space truss prong bolts . If you are looking for requirements for steel space truss fittings then the prong bolt specification can not be ignored. This is a little-known accessory but plays an essential role in the steel space truss structure. So what are the specific specifications for prong bolts? Let's follow the article on steel space truss prong bolts below to know the answer.

Steel space truss prong bolt pattern . Thread specifications of mesh high-strength bolts from M12 to M64 can be found in detail: "High-strength bolts for ball joints of wire mesh spacer bolts GB / T16939-1997", where M20 and above down is mostly used in decorative mesh space truss structures . Because there is a fixed relationship in the structure of the buttons, the screw length of each specification of the high-strength bolts of the mesh is also fixed, please refer to the relevant information for details. Since the mesh spacer high-strength bolts are matched to the telescopic sleeve, the bolt specifications are determined according to the cage pressure in the design of the joint.

1. Regulations on quality inspection and acceptance of prong bolt specifications

Quality steel space truss prong bolts . The main basis for the inspection and acceptance of products of high-strength bolts in the mesh space truss is the "Construction quality acceptance code of steel structure engineering GB50205-2001" and "Test standard for steel structure engineering". and acceptance test in the form of wire mesh JG12-1999."

In the "Quality Test and Acceptance Code for Steel Structure Construction GB50205-2001", high-strength bolts are used as standard parts for inspection and acceptance. For details see Article 4.4. Furthermore, Clause 4.4.5 specifically describes the requirements of the "surface hardness test".

"Standard for inspection and acceptance of steel space frame truss frame JG12-1999" specifies the main test items for high-strength bolts: stiffness, and steel space truss prong bolts with marks crack and length.

4. Solid form requirements in prong bolt specifications

Design steel space truss prong bolts . Shaped as shown, especially on a slotted screw and with a deep groove section near the head, where the screw (pin) on the "fit" (without pattern nut) tube is embedded. When installing, turn the wrench to drive the bolt into the bolt ball, while the pin slides in the chute. When the bolt is tightened into position, the tightening screw is exactly at the position of the deep groove, now turn it. Tighten the tightening screw so that the groove falls into the deep groove, achieving the effect of resisting and loosening.

3. Rules for approving unsatisfactory prong bolt specifications

Review the quality of steel space truss prong bolts . When one of the following situations occurs, the product is approved as “unsatisfactory”.

(1) There is no quality certificate for welding consumables when entering the site or the type and specification of welding consumables does not match the design.

(2) There is no professional certificate of the welder or the approved scope and its validity period does not meet the requirements.

(3) Welding techniques for steel structures do not provide reports on inspection of the welding process, non-destructive testing of welds, weld leg size, weld surface quality according to design requirements.

(4) Welding nails (rivets) cannot provide welding nails and report on inspection of welding and steel bending testing as required by the design.

(5) Any indicators in the inspection report do not meet the inspection standards, re-inspection is not in accordance with regulations, there is no definite remedy.

(6) The total number of lots represented by random samples in the inspection report is less than the actual number.

Error of prong steel space truss bolt . To avoid the case that the prong bolt parameters are not approved because they do not meet the above technical requirements, you need to "choose the gold deposit" from reputable companies and especially have a lot of experience in the profession.
