Layout Principles and Structural Selection
Section 1 Layout Considerations
Article 2.1.1 The plane layout of the warehouse shall be determined after strategic comparison based on the conditions of technology, topography, engineering geology and construction. Frequency 2. 1.2 The cluster should be arranged in single row or multiple rows (Figure 2-1-2).
Figure 2-1-2 Schematic diagram of cluster layout (single row, multiple row) design conditions
Article 2.1.3 For the plane shape of the cluster, two rows should be used. For the circular cluster, the connection method of the cluster wall and the outer tangent should be used. For the cluster with a diameter greater than or equal to 18 meters, the vertical arrangement should be adopted. Article 2.1.4 When the diameter of the cluster is less than or equal to 12 meters, the multiple of 2 should be used. When it is greater than 12 meters, the multiple of 3 meters should be used. For the cluster with the tangent wall and the outer tangent section, the length should be 2.1.5 When the length of the unit exceeds 50 meters or the total length of the rectangular warehouse supported by the unit exceeds 36 meters, a shrinkage wall should be provided.
Article 2.1.6 If there is a significant difference between the unit and the adjacent buildings and structures or the compressibility of the foundation of the warehouse, measures should be taken to prevent uneven shear settlement.
Article 2.1.7 For the units across the railway, except for rock, stone soil and old clay foundation, the influence of ground settlement on the construction limit of the railway should be considered. Article 2.1.8 No special site is set up in the place where it is necessary. When it is necessary to set up, the unfavorable factors of the non-resistant structure and foundation should be considered. Section 2.1. For a simple warehouse with a vertical length greater than 10 meters, it is not advisable to set up a factory building with end sections on the top.
Section 2 Structure Transparent Type
Section 2.2.1 The warehouse structure can be divided into six parts: the upper structure, the roof, the wall, the warehouse bottom, the lower supporting structure (simple wall structure) and the foundation (Figure 22-1).
1 Commercial Structure
" ,3. The effect of the construction is also the principle, 1. In the pulse, it is necessary to use the same thickness of the warehouse, the angle of the warehouse and the angle of the warehouse. The following 2.2.2 should be used. The following principles can be used according to the following conditions: 1. The vertical and horizontal small load is less than 15 meters: d.
in! --- Overall thickness (width meter), medical screen color internal inspection (mm).
2. The short-shaped grinding degree can be used as 1/241/310 of the known side road degree. 3. The angle of the end of the flat rotation can be used as 1/20-1/30 of the side of the precious degree. 2.2.3 The selection of simple low-viscosity warehouse structure should consider the following requirements:
", the material is unobstructed.
", the direction of transmission is clear, the structure is reasonable, the shape is simple, and the filling is light.
The commonly used warehouse bottom can be sent to the type shown in Figure 2-2·3. Ie:

) The error is ten and the medium is continuous, and the same potential rate, > half the depth and chemical energy are not heavy, the insect is full of more requirements, the medical environment box, the small energy is the most channel type, and it is in the warehouse lower part of the enterprise that the structure is good. You can choose the old Guiyi 2.2.4 item
music. Simple collection, selection and internal support and other types (Figure 2-2-3). The selection of the lower bearing structure, the type of formation, the cost and the process requirements shall be determined by comprehensive analysis. For commercial silos with a diameter equal to or greater than 18 cm, it is advisable to select a type of common support for the structure and the inner wall. When the structures or the silos and their adjacent buildings (structures) are at a certain distance and must be connected to each other according to the process requirements, it is advisable to use a supporting structure connected with sufficient support length. Article 2.2.6 The selection of the foundation of the silo shall be determined based on the comprehensive criteria of the foundation conditions, the upper load and the type of the upper structure. When the expansion joint is set according to the provisions of Article 2.2.5 of the silo, the expansion joint shall be changed to a through type, the foundation shall be disconnected, and the requirements of settlement continuity shall be met. In the foundation area, the requirements of anti-blocking shall also be met.
Article 2.2.7 For round silos with a height of less than or equal to 10 meters, the top plate of the silo can be used. When the diameter is equal to or greater than 15 meters, steel pipes can also be used for load-bearing structures,
, and spherical shells.
Article 2.2.B For round silos with a height of less than or equal to 10 meters, when there are screening equipment in the building, the floor and the hollow structure should be supported on the concrete wall of the same thickness. When the reinforced concrete frame building is used, the frame columns should be directly supported on the ring of the top of the building, and a longitudinal connection should be provided at the column (on the ring beam). Article 2.2. All silo structures in the core area should meet the following requirements:
1. The supporting structure under the silo of the same shape. It is advisable to use a wall support or a structure supported by the silo and the interior.
, the building should use reinforced concrete frame structure, and the structural reinforcement should use lightweight materials.

When the thickness of the vortex bucket wall meets the requirements of the 2.2.2 policy of this code, deformation verification can be omitted. Third, the degree of deformation verification of the warehouse bottom is carried out. The maximum width (fx) of the warehouse is allowed to be u.2 meters. The degree of deformation can be calculated by the formula recorded at that time. When the core E force of the whole warehouse does not meet the requirements of 4-3-2 of this code, the overall load resistance of the warehouse shall be verified. The rated safety factor shall not be less than 1.5. When the load is still high, it should not be less than F1.2. 4.1.3. In the simple warehouse of the pool area. The overall connection should be more tightly calculated, and the other parts should be integrated. The bottom of the warehouse can be tested without resistance. The second section of the warehouse, the warehouse and the warehouse structure are the shape of the simple warehouse. The color is any uniform design, and the hatching 4.2.1 disease
original opening and closing 7 are listed:
first, the warehouse shape is relatively fast, and the single warehouse calculation can be corrected. The shape of the simple warehouse is determined by the structure, and the internal force of the thin mold can be calculated with a small formula. When the quality is adopted and the load is competitive, the positive condensation is missing or other forms of Yao's original other hall integration. Violate connection. Or the same energy body connection, the connected edge should be calculated to continue to drink the effect of the effect of the conversion element in the axis of the special pregnancy liver pain membrane is called the calculation
