Damage causes and reinforcement measures of steel space frame structure

图片
  The cause of damage to the steel space frame structure 1. the overload of the load, the project construction code changes, resulting in the reduction of the bearing capacity of the structure of the grid. 2. the steel structure due to environmental changes, shape changes, distortion and other changes, resulting in the overall performance of the grid frame steel pieces become poor, crack. 3. Deformation occurs due to temperature difference, resulting in damaged deformation of the steel structure. 4. Chemical corrosion and other electrolytes corrosion of steel structures. 5. Construction operations shall be carried out in violation of normal operating procedures. Reinforcement measures for steel space frame structure 1. Local and along the lengthening of members, enhance the overall stress of the network frame. 2.I ncrease additional support, reduce the level of physical strength, adjust the distribution of space frame  load. 3.H igh - strength zipper reinforcement, improve the...

Safe and environmentally friendly windbreak and dust suppression wall fully enclosed space structure

图片
  As the environmental storm continues, many open-air bulk cargo yard due to dust pollution problems were shut down or closed for rectification, then how to implement the whole closure of the site to save the most money? The use of existing wind-proof dust wall to transform the fully enclosed material field. The main structure of the yard closed adopts the steel structure of the space frame, the maintenance structure adopts the steel structure color plate and the glass steel light belt closed, the shape is space frame type, flat-type mainly, the use of column-free design, equipped with fog gun dust suppression and water spray device, to achieve all material into the shed, reduce the loss of material in the operation, prevent dust suppression. Wind-proof dust wall transformation full-enclosed silo technology to make full use of the existing field of wind suppression dust wall, the use of a new design concept, after the transformation of the fully enclosed silo not only to achie...

"Green factory" steel space frame structure plant

  Steel space frame  structure plant is described as "green factory", space frame  plant system has light weight, easy installation, short construction period, good seismic performance, quick investment recovery, less environmental pollution and other comprehensive advantages. Compared with reinforced concrete structure, steel space frame structure workshop has the unique advantage in the development of "high, large and light". Recently, in the field of construction engineering, there has been a product structure adjustment, for a long time the situation of concrete and masonry structure as main type  is changing, steel structure truss workshop with its own advantages attracted attention  in the industry, has been reasonable and rapid application in the project. LF is a professional manufacturer and engineering company for space frame and steel structure projects.Do you have a construction project we can help with?

Structural characteristics of space frame

图片
The space frame  is a form of spatial  frame  structure. Most of the space frame  structures are made of pipe  and bolt-ball  nodes   .The space frame  structure is generally composed of a quadrangular cone, a triangular cone and a hexagonal cone. Advantages and characteristics of space frame structure  as followed, 1. Space work , simple and direct  way of force transmission, suitable for large span, no column  roof structure. 2. The structure is light in weight and has good economic indicators.   Compared with the flat steel roof frame with equal span, when the span is less than 30m, the steel quantity can be saved 5~10%;When span > 30m, it can save 10~20%. 3. Large space stiffness, small dead weight and good seismic function. 4. Simple construction and installation;   Less type of steel pipes and nodes;  C onvenient for t ransportation, storage, loading and unloading, assembly . 5. Flexible plane layout of the s...

The difference between steel structure and space frame

图片
  Space frame  structure belongs to  the steel structure  type .  But the difference between space frame  and steel structure lies in the connection mode, the use of steel structure materials and structural form and structural system. First ly , from the connection mode , a.  The nodes of the space frame  are regarded as hinged and are usually connected by bolts. b.  S teel s tructur e  joints are considered to be rigid contacts and are usually welded. Secondly, f rom the use of materials and form: a . The steel structure is based on the steel structure material b.   T he space frame  is said from the form of structure The space frame type include steel and aluminum alloy and so on . I n the practical application ,  the majority  is steel space  frame . Steel structure has steel frame, steel portal  frame and other forms. Thirdly, s tructurally s ystem, a. The space frame  belongs to the space frame ...

The advantages of reticulated shell

图片
The structure of reticulated shell can be classified according to the arrangement of the rods: single-layer reticulated shell and double-layer reticulated shell. Generally speaking, single-layer reticulated shell can be used for small span (generally below 40m), and double-layer reticulated shell can be used for large span.  D ue to less bar s , light weight, simple node, convenient   construction,  s ingle-layer reticulated shell has a better technical and economic indicators, but single-layer reticulated shell surface  has a p oor external stiffness and stability, a variety of factors will   affect  the internal force and deformation of the structure  obviously.   Thus it should be  noticed including, the layout of structure bar, roofing materials  choosing , the determination of calculation mode, i mplementation of structural measures , c onstruction and installation of the structure. a . The bars of reticulated shell structure mainly...
