Box-shaped strip of reinforced concrete foundation beam design

Consider reinforcement. (C) of reinforced concrete strip foundation beams of the cases of box board calculations. Box-shaped strip of reinforced concrete beams based on disability under lateral pressure side, the hydrostatic pressure and vertical pressure at one end of the embedded solid, hinged at one end of the flexure and compression calculations. (D) of reinforced concrete strip foundation beams of the floor box calculation. Article type of reinforced concrete box foundation floor beams connected by the local body bending and bending reinforcement of the two methods, the overall calculation, by equivalent stiffness of the cross-section flexural members beams are calculated. Click here to Nei Lizhi the beam support Reinforcement. (E) of reinforced concrete strip foundation beams of the torsion box calculation: Box-shaped strip of reinforced concrete foundation beam because of the role of the cabinet, the lateral torsional stiffness, the heap for the workshop from the box set so gl beam lateral rotation, has a large torsional characteristics, is a good base form. This beam, the role of the cabinet, there is a cross section cut in the center. When the role of the vertical load through the cross-section shear center, the box will not happen to reverse the effect of cross-section, but does not load cross-section cut through the center, the box beams will have a reverse effect, need to calculate the effect of external load under torque. Fourth, reinforced concrete strip foundation box beam construction requirements (1) Box-shaped strip of reinforced concrete foundation beam roof, according to box the width of the situation, the use of precast reinforced concrete hollow slab or prestressed concrete panel casting steel 150mm ~ 2OOmm made of steel concrete composite slab form. (2) box of reinforced concrete strip foundation support beams separating wall plate when asked to meet the L / B ≤ 2 pm. Do not add. (3) Box-shaped strip of reinforced concrete foundation beam, the single plant and multi-plant location of the wall column support. Thickness of not less than the width of the column section plus 2c (Fig. Cool

support the wall plate width b +2 c. Where: b - the width of the column c - is ≥ 200ramIJ/l11 a:; j1} 1Ij {; iI .... 1} BIllL Q in Figure 7 Location of wall support plate wall support 8-bit column width construction requirements pull (4) actinium concrete strip foundation beam side box minimum thickness of scale is ≥ 200ram (5) Concrete strip box actinium minimum thickness of foundation beams shaped floor scale is ≥ 300rnm. (6) of reinforced concrete strip foundation should be a waterproof box,[link widoczny dla zalogowanych], when the compensation effect is not too much water to reduce the time. VI Conclusion industrial building single and multi-column foundation, pile driving conditions are restricted, only the use of the natural foundation of a possible case, when the strip foundation design can not meet the strength and foundation settlement request. Concrete strip of steel beams and box foundation form the basis of one of the ideal. It based on the engineering geological conditions and foundation requirements,[link widoczny dla zalogowanych], meet the construction permit in the case of settlement, increase the buried beam,[link widoczny dla zalogowanych], using bar-style box foundation beam. Digging the soil with the weight on credit, to compensate for the strength of the foundation, the value at the same time, foundation strength values increased with depth intensity can be modified to achieve greater value. This form of the natural foundation, compared with the artificial foundation, can reduce construction costs, saving investment. Box-shaped strip of reinforced concrete beams based on the characteristics of both a strip foundation. Fork with a box foundation stiffness, the characteristics of internal force can be adjusted for differential settlement within Liangchang Fan with ability to adjust. The box of reinforced concrete strip foundation beams. In the single-and multi-industrial plants, workshops or library to overcome the load on l through the heap from the differential settlement and reverse, with good results. Especially in coastal soft soil. Refrigeration Equipment Refrigeration Equipment Factory of Shanghai Kyushu Corporation, the ninth ship Design and Research Institute in the immediate past six years of professional manufacturing factory has production and assembly type cold storage, features, laboratory, nearly ninety units. Products are sold to Jiangsu, Zhejiang, Jiangxi, Anhui, Shandong,[link widoczny dla zalogowanych], Shaanxi, Sichuan, Liaoning, Shenzhen, Algeria, Thailand. She capacity from 10rn. ~ 800m. Refrigeration unit. In the large-scale adoption of open,[link widoczny dla zalogowanych], semi closed most small refrigerator. Row tube evaporator design and manufacture of pre-deformation self-bending machine, smooth and seamless curved bleed at the nose radius R = 70m/raN, the ellipse has controls in 2 / 100 or less. The gradual introduction of electronic control systems have digital display of temperature, process control techniques o1990 defrosting in cold She assembled the Department of Commerce production license approval. The country through 24. Shanghai by seven, while the Kyushu plant in refrigeration equipment in 24. The first validation pass. According to \91 Kyushu refrigeration plant is 38,650 yuan per capita. Nine homes, according to the board leadership and the spirit of Kyushu, according to nine hospital approach to development, to build on the existing plant will be accomplishing the Kyushu Institute research and development and production base in September, into the appropriate human and material resources. And to attract foreign investment. Inline expansion, develop new products to create conditions in order to further development. Academy of Sciences Department of editing and publishing 31
