Steel Space Frame Structure Supplier - SAFS

       The space frame ball valve can ensure that the space frame can achieve a large span to a large extent, and it is also conducive to the space frame to make various unique shapes. However, each welding ball has different advantages and disadvantages according to the needs of different space frame. Let's take a look at some common advantages and disadvantages of space frame accessories processing. The common node bolts and ball nodes of the space frame are realized by connecting the rod and the ball through high-strength bolts. The end of the rod is connected to the sealing plate with equal strength (the diameter of the steel pipe is less than φ 75.5) or the taper head (the diameter of the steel pipe is less than or equal to φ 75.5), the bolt ball is used as the split surface, and there is a hexagonal sleeve between the split surface and the sealing plate or the taper head. A small hole is opened on the sleeve, and a fastening pin is placed, the pin is embedded in the groove o

Corresponding protective measures should be taken for the lifting and stacking of finished products of the space frame  structure to prevent damage to the surface of the components; materials, semi-finished products and finished products should be stacked reasonably to ensure smooth roads and keep the workshop clean. Before the start of the space frame  structure project, make a safety technical disclosure to all construction personnel, and make a disclosure record; all personnel participating in the processing and manufacturing of the space frame d structure must strictly implement the safety operation regulations for this type of work and the relevant current national technical regulations; must implement t he principle of "three no harm": neither harm others; do not harm your self; do not be harmed by others. Seriously participate in the factory safety meeting, hold every pre-shift safety meeting well, and make careful records. Safety precautions should focus on preventin

Bolt ball is an accessory of steel structure space frame , but it plays a vital role in the whole construction project. There are also many builders who like the bolt ball made by Chinese steel structure space frame  manufacturers very much, because its quality and price have certain advantages. The following is a brief description of the method of measuring the angle of the bolt ball. The angle between the axes of the two adjacent screw holes of the bolt ball is required to be ±30. This parameter is very important. In the standard, the diameter of the bolt ball is generally from 100mm to 260mm. The number of screw holes varies, generally 3-9 holes. The axis of each screw hole passes through the center of the ball. When the bolt ball is processed, the position of the screw hole on the bolt ball is marked in the angular coordinate space on the drawing. For bolt ball space frame  calculation, when measuring the bolt ball angle, first screw the bolt ball on the lower threaded core rod and

Eight safety measures for large-scale steel structure platforms, China SAFS Steel Structure will introduce to you: 1.  The steel structure platform should be equipped with a load limit plate, especially the steel structure platform with hydraulic lifting channel, and the limit load should be marked in a prominent position; 2.  The placement point and the upper tie point of the steel structure platform must be located on the building, and shall not be set on construction equipment such as scaffolding, and the support system shall not be connected with the scaffolding; 3.  The concrete beam slab at the placement point of the steel structure platform should be embedded and connected with the bolts of the channel; 4.  The horizontal angle between the wire rope and the channel should be 45 degrees to 60 degrees; 5.  The tensile strength of the beams and columns of the tension nodes on the upper part of the steel structure platform should be checked to ensure the safety of buildings and cha

       With the completion of the positioning of the steel truss of the last unit, the large-span unequal-length trusses of the main roof of the Suzhou Bay Cultural Center Grand Theater have all slipped into place. It is the first case of "compensation method" sliding construction of the special-shaped sapce frame   steel structure roof , which is the "finishing touch" of the Grand Theater. The roof truss for the sliding construction has a total of 9 units, with a total weight of about 350 tons. The overall shape is "C", with a longest span of 41.3 meters and a duration of 48 hours. The project adopts the domestic advanced sliding technology of large-scale sapce frame  steel structure. Workers first set up a working platform on the south side of the Grand Theater, hoisted 260 large steel components to the platform, and welded and assembled them into 9 steel trusses. After connecting the auxiliary sliding device, the pulley is installed at the bottom of th
