Drainage requirements of indoor mezzanine floor warehouses

Inside the warehouse building there will be a mezzanine floor. Product shelves and valuable products, so the drainage system has an important part The vertical deflection for metal roofs is controlled by limits near the (eave) ends and edges (roof edge) in the area of the roof sheet. The deflection behavior of the roof sheet will occur with radius. 

Note : Mezzanine Floor is a shelf. suitable for storing materials parts of the product which can create additional space on the high side of the building worthwhile by making a mezzanine floor It is a large structural system that is strong and durable. can bear a maximum weight of 1,000 kg / square meter, please contact rnbproduct

Curvature equal to the radius of curvature with the purlin While the limit of deflection increases with span length (spar), therefore it is not possible to clearly define the maximum deflection limit of the roof sheet. Control the behavior of other elements within the building that are related to each other. The requirements in this manner are covered in the partitions, ceilings and equipment.

  along the entire length of the gutter There is a need for drainage after the roof has slumped under. design payload Because the perimeter framing may be able to withstand deforms more than the first Interior purlin. Preventing the occurrence of water scramble between the eaves and the first inner purlin to reduce concerns about roof drainage maintenance The use of metal roofs with large relative slopes (relative tarte pitchers) can help maintain good drainage capacity. The roof must have a minimum slope of about 2.10 centimeters per meter (1/4 inch per foot). The play of purlins and catches must be checked to ensure roof drainage. Under the load it can still work well. The weight of the cargo consists of Fixed payload and additional payload (superimposed loads

  The drainage system is typically located at the eaves. which connect to internal and external drains or to the ground Therefore, it is not necessary to specify the location of the drainage point. But it has to be done. The details of the pipes and other parts are also separate from the details of the structure and the roof.

Design considerations related to exterior building walls deformation of the building frame and lateral movement

In practice The design considerations of the building frame are separated from other non-part systems. of the structure and components of the building Foundations and superstructures are considered core structures, excluding curtain walls and roofs.

  Cladding structure interaction The main method of controlling the interaction between the external cladding of a warehouse mezzanine floor building. Or product shelves and structure is to create a joint to create a working behavior that is separated from each other. The separation will help prevent the load from occurring. from the movement of the main structure and the structure of the building to act on the exterior wall This can be done by making joints on the exterior walls of the building. and by fixing the exterior building wall to the structure in a statically determinate manner. Compatibility analysis for both exterior wall and structure, considering composite structure.

  In addition to making joints that are appropriate Another important design element is the joint behavior The joint grooves must be filled with sealants & gaskets. Movement must also be controlled in order to perform the intended function of the material. The external building walls can be either a single material, such as a factory-made metal wall, or can be a combination of different elements, such as masonry walls and windows. Each type of exterior building wall has a specific design.

Vertical support of external building walls can be done in 3 ways.

  Method 1: For 1-2 storey buildings, you can use the method of making support points for external building walls on the foundations. 1st year of the building frame to be joints for stabilizing and lateral loads.

  Method 2: External building wall system that consists of prefabricated walls with dimensions equal to the width between The main structure (bay length spandrel panels or bay-sized panels) can use columns to make can be a support point These joints should be made to the proper detail in order to maintain the condition. of the joint to be a determinate as mentioned above.

  Method 3 of making support points for external building wall systems that must be made together with support points. Outer building frame installed along the depth of the building (transverse beard frame), which the method of making support points all of these Special considerations must be given to the cohesion of the building frame. and external building walls in high-rise buildings

  In addition to deformation of the building frame due to static and live loads, wind loads are the main loads that affect the performance of external building walls. Usability is good, too.

  for evaluating lateral displacement of building frames It is advisable to use a standard calculation. Wind load and building response of the Engineering Institute of Thailand (EIT 1311), which has been specified that wind speeds with a 10-year retrospective period can be taken into consideration Because of the ability to work well, not related to the safety of life and property of building users The wind speed with the 50-year period is the design wind speed for strength. Which will be considered from the event that the opportunity was born less and more violent Therefore, in order to be consistent with the design objectives according to the EIT 1311 standard that says “In order for the building to be able to use normally in strong conditions, there is a chance to happen often. during the useful life of the building.” Therefore, it is recommended to use 75 percent (plus or minus 5 percent) of the velocity with a return period of 50 years as a reasonable estimate. And the wind pressure value is equivalent to the wind speed in the return period of 10 – 15 years, which is the wind speed that often occurs during the lifetime of the building.
