Gable Frame Steel Structure Building Gable Frame Steel Structure Building

Gable frame steel structure building is a typical construction system. Its upper structure consists of steel of parapet, gutter, roof purlin, steel frame, and wall purlin, etc. This kind of building offers a series of advantages and features.
1. This product is lightweight and its steel volume of bearing structure is in the range of 20 kg to 50kg per square meter. Its dead weight ranges from 1/20 to 1/3 of reinforced concrete structure. Therefore, this structure greatly reduces damages from earthquake and lessens its foundation costs.
2. It comes with short construction period and high economic benefits.
3. The arrangement of columns is quite flexible.

Mechanical Principle
This product uses lateral bracing consisting of columns and beams as its main stressed structure. To improve its longitudinal stability, column bracing and roof bracing are available.

Constituent Parts
1. The main bearing frame is gable frame. Steel frame columns and beams are machined from H beam steel. All kinds of loads are passed to the house base by columns and beams.
2. Purline and wall beam are thin-walled, cold-formed steel sections usually C section steel and Z section steel. The steel section bears the pressure of roof and wall panels and passes to columns and beams.
3. Roof and wall cladding are pressed metal panel or color-steel sandwich panel.
4. Thermal insulation materials for roof and wall include polystyrene foam, polyurethane, rock wool, glass wool, etc.
5. All the braces including column bracing and roof bracing can be divided into two categories and they are rigid support and flexible support. The former is produced from hot rolled steel sections as angle steel. And the latter is round steel bar. The tie rod is circular steel tube.

Structure and Properties
1. Purline is used to ensure the integrity of this steel structure building, reducing the number of roof bracing. Most braces are made from round steel and are lightweight.
2. Columns and beams use rods with variable cross-sections, saving building materials. But these rods are thin, having a high demand for manufacturing, transporting and installing.
3. Frame member has smaller bending and torsional stiffness.

Our gable frame steel structure building is manufactured according to the domestic design standard CECS 102:2002 Technical Specification for Steel Structure of Light-weight Buildings with Gabled Frames. It is widely used in logistics center, hypermarkets, gymnasium, exhibition gallery, mobile homes, as well as lightweight factory or factory with lightweight crane or medium weight crane, and more.

Cross-section Properties
Generally speaking, transverse span is of 9 to 24 meters and column is ranging from 4.5 meters to 9 meters. When the transverse span of plant is within 15 meters and column height is less than 6 meters, the roof frame should adopt steel frame with uniform cross-section. Otherwise, steel frame with variable cross-section is applicable.

  • Truss Steel Structure BuildingCompared with solid web girder, our truss steel structure building comes with higher bending strength because the tension and compression section are arranged on both ends. While in the aspect of shear resistance, it will pass shear force to the support gradually by reasonable arrangement of the web member. All in all, our product makes full use of materials strength, suitable for various span roof structures. More importantly, complicated stress states will be converted into simple tension and compression stress state ...
  • Floor Decking Steel SheetFloor decking steel sheet or composite floor decks refers to a kind of profiled metal sheet, coming with high rigidity, tensile strength or compressive strength. It is considered as permanent template of concrete floor. Also it combines with concrete, resulting in forming composite floor decks. This product can save a large number of permanent templates and framework supports. Also, the volume of concrete is reduced and its permanent load is decreased. Our sheet is ideally suitable for high- rise building and earthquake zone.
