What are the advantages and disadvantages of space frame ball valve nodes

-

      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 φ75.5) or the taper head (the diameter of the steel pipe is less than or equal to φ75.5), 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 of the high-strength bolt inside the sleeve, the high-strength bolt cap is stuck in the sealing plate or the cone head, and the other end is screwed into the bolt ball through the pin.

Advantages of common nodes of space frame:

1. There is a complete set of standard drawings of parts to guide production, which is convenient for factory processing. Different manufacturers can divide labor and cooperate to segment the market;

2. On-site installation is convenient and fast, shortening the construction period and improving efficiency.

Disadvantages of bolt ball joints commonly used in space frame frames:

1. The angle of the rod should be considered in the design. If the angle is not good, the bolt ball is very large;

2. The bolt ball is a solid ball with a large unit weight and is difficult to install on site;

3. High precision of each accessory is required.

We can see that the price of the space frame bolt ball is very low, and the cost can be reduced on the premise of ensuring the quality. Therefore, in large-scale space frame projects, the use of hollow balls is not only beautiful but also ensures the reliability of quality. Through the function of this product, everyone can have a better use effect, and can complete the work more quickly with its help.

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa...

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyrami...

Space frame has become one of the important fields of modern architectural structure

Since the 20th century, the spatial structure has been greatly developed all over the world. The space frame structure is a kind of space grid structure. The so-called "space structure" is relative to the "plane structure", which has the characteristics of three-dimensional function. The space structure can also be regarded as the expansion and deepening of the plane structure. Since the advent of the space structure, it has been welcomed by people for its high-efficiency mechanical performance, novel and beautiful form, and fast and convenient construction. In stadiums, convention centers, cultural facilities, transportation hubs and even industrial plants that require large spans and large spaces, space structures can be seen everywhere.   After a century of continuous development of space structure, in terms of structural form, in addition to space frame and reticulated shell, membrane structure, tensegrity system, open and close roof, and foldable structure are...
