5. Противопожарные требования и защита конструкций от коррозии Все металлические детали и сварные соединения должны быть защищены антикоррозионными покрытиями. Состав и способ нанесения антикоррозийного покрытия должны назначаться согласно требованиям СНИП Ш-23-76. Анкера плит перекрытия защищают цементным раствором согласно СНИП П-28-73. деревянные Расстояния от дымового канала до древесины должна быть не менее 380 мм. В тех случаях, когда расстояние 250 мм - выполняется прокладка из войлока, которая предварительно смачивается в глине. Обрешетка обрезается на расстоянии 130 мм. от дымовых труб.
2. Factors of development and placement Areas of the construction complex are developing in all districts, however, the vast majority of enterprises gravitate to areas of industrial construction. The raw material factor has the greatest influence on the placement of enterprises in the construction complex, in particular, the production of construction materials. The approximation of production to raw material bases is caused by large amounts of raw material consumption per unit of production and its low transportability. Thus, transportation of sand or gravel by motor vehicle for 50 km is 10 times more expensive than their extraction. For the production of 1 ton of cement clinker, 1.5-2.5 tons of limestone and clay are used, 1 ton of lime - 2 tons of limestone, and 1 ton of ceramic pipes - up to 1.5 tons of clay. The share of raw material costs is 15-25% in the cost structure of production.
1. Construction complex The construction complex is a set of branches of material production and design and research works that provide capital construction. The construction complex includes the following branches of material production: construction, production of construction materials, production of construction structures and parts. In a number of scientific studies, the structure of the construction complex is understood more broadly: it also includes construction road engineering, special infrastructure (research and experimental design organizations, higher and secondary special educational institutions, vocational schools, training courses for construction personnel; banking institutions that finance construction; organizations for the material and technical support of enterprises included in the complex; specialized transport).
4. Constructive solutions The project envisages the planning of the territory with subsequent cutting of fertile soil. The foundations for the external and internal walls are designed as strip monolithic ones, sealed with sand preparation with a thickness of 100 mm. A reinforced concrete belt with a thickness of 150 mm is arranged on the foundation blocks. Horizontal waterproofing of the foundations is performed from two layers of roofing material with waterproof mastic. The outer walls of the basement, which are in contact with the soil, should be coated with hot bitumen in 2 coats. The masonry of the walls is made of hollow effective brick M-125 on mortar M-25. Jumpers - prefabricated reinforced concrete blocks. When performing the work, it is necessary to ensure that the load-bearing bars of the jumpers were locked from the abutment side of the floor elements and staircase landings. Lay the jumpers on the M-50 mortar. Ceilings - designed from prefabricated reinforced concrete panels with voids. All panels are anchored in the masonry of the outer walls and on the middle wall. The insulation of the attic floor is expanded clay. Panels are laid on a layer of M-100 cement mortar. Wooden beam ceiling, beams 160х140 mm.
