Revision Notes
This standard is revised by the Second Design Institute of the Ministry of Machinery Industry in conjunction with relevant units based on the notification of the former State Construction Commission (81) Jianfa Shexue No. 546 to the original "Basic Rules for the Unification of Factory Buildings" TJ6-74. During the revision process, the compilation team conducted investigations and studies, starting from my country's current technical and economic levels, considering the possibility of development, and still focusing on the regions with a certain foundation of building industrialization and the prefabricated reinforced concrete structure factories that need to be further unified and improved throughout the country. On the basis of summarizing the practical experience and theoretical research of the "Basic Rules for the Unification of Factory Buildings", the effective provisions in the original rules are retained, some new contents are added, and the arrangement of chapters is adjusted. This standard is now composed of four chapters: general principles, basic regulations, single-story factory buildings and multi-story factory buildings. The main contents of the revision include: the setting of expansion joints, the specific dimensions of contact dimensions and insertion distances, and the positioning of side columns of multi-story factory buildings; the setting of seismic joints, the use of exterior wall panels and blocks, and the positioning of major components have been added.
In the process of implementing this standard, if you find that there are places that need to be modified and supplemented, please send your opinions and materials to the Second Design Institute of our department (Shiqiao Road, Hangzhou) for reference during the revision.

Chapter 1 General
Article 1.0.1 This standard is specially formulated to standardize and serialize the geometric dimensions of the main components of factory buildings to facilitate industrial production. Article 1.0.2 This standard applies to:
1. Design of prefabricated or partially prefabricated reinforced concrete and mixed structure factories;
2. Preparation of standard design drawings of factory building components. Note: ① Design of steel structure factories, factory buildings that are restricted by conditions, cast-in-place reinforced concrete structures, factories with special requirements for factories, or factories that will be significantly unreasonable in terms of technology and economy according to this standard, some provisions of this standard may not be implemented; ② Factory buildings that use new technologies, new structures and new materials may not be restricted by some provisions of this standard. Article 1.0.3 When determining the design schemes of various factories in a construction site, the types of components should be unified.
Article 1.0.4 On the basis of technical and economic rationality, the shape of the factory should be as simple as possible to avoid the height difference in the vertical and horizontal spans and multi-span factories. Article 1.0.5 When preparing the standard design drawings of factory building components, components with the same purpose should be used to achieve maximum interchangeability. Article 1.0.6 In addition to complying with the relevant provisions of this standard, the design of factory buildings shall also comply with the provisions of the current relevant national standards.

Chapter II Basic Provisions
Article 2.0.1 The base value of the plane and vertical coordination modulus of factory buildings shall be the expanded modulus 3M. ​​
Note: M is the basic modulus symbol, 1M is equal to 100mm. Article 2.0.2 The cross-sectional dimensions of factory building components should be upgraded according to vertical M or 1M.
Article 2.0.3 The vertical and horizontal positioning of factory building components should adopt a single axis. Article 2.0.4 The vertical positioning of factory building components can use the corresponding design elevation line as the positioning line.
Article 2.0.5 The length, width and height of the components referred to in this standard are all marked dimensions. The surface that defines the marked dimensions should be the positioning plane of the component. Article 2.0.6 For single-story reinforced concrete buildings, it is advisable to adopt a frame structure scheme in which the lower part of the column is rigidly connected and the top of the column is hinged to the roof truss or roof beam. Article 2.0.7 For multi-story reinforced concrete buildings, the connection between beams and columns should adopt a frame structure scheme in which the horizontal part is rigidly connected and the longitudinal part is hinged or rigidly connected. Article 2.0.8 For the roof of a single-story building, it is advisable to adopt a non-rubbing structure scheme with plate paving. When there is a clear advantage in construction conditions or component selection, a friction structure scheme can be adopted.
Article 2.0.9 For the roof and floor of a multi-story building, it is advisable to adopt a non-secondary beam structure scheme with plate paving.
The load parameters of the roof truss or roof beam can be 2.0, 2.5, Article 2.0.10
3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0 kN/m2. Note: The above load parameters do not include the deadweight of the roof truss or roof beam, the weight of the support, the weight of the skylight and the load of the suspended crane.
Article 2.0.11 The wind load on the factory building structure should adopt the basic wind pressure values ​​of 0.35, 0.50 and 0.70 kN/m2.

Chapter 3 Single-story Factory Building
Section 1 Span, Column Spacing and Height
Article 3.1.1 When the span of the factory building is 18m and below, the expanded modulus 30M series should be adopted. When it is above 18m, the expanded modulus 60M series should be adopted (Figure 3.1. 1).
