Wood floors and water-sectional shape analysis section

W is proportional to the maximum bending moment and cross-sectional shape of the cross-section factor analysis can be undertaken, W bigger the better. On the other hand, the number of materials used and the cross-sectional area A related. The ratio of W and A is available

To determine the reasonableness of the two cross-sectional shape of the larger cross-sectional ratio is more reasonable. By Table 2, these three kinds of wood floor cross-sectional shape, the hollow structure of the most reasonable; opening

Due to the lower half of the plate-type structure has opened a radius of 11 mm round the mouth, so that the central axis rise, leading to larger yc, flexural modulus of section smaller. Simultaneously from three-point bend wood floor

Qu stress analysis perspective, the farther away from the central axis, the normal stress greater. By analyzing that, when subject to bending force, the bottom opening for wood flooring type structure to withstand large tensile stress.tongue and groove ceiling

Three kinds of wood flooring sectional structure, each for different occasions. Wood floors open type structure on the surface of thick, abrasion resistance, impact resistance, and because of the lower surface has a semi-circular groove, on the ground water can play a role in the diversion; hollow structure of the wood floor, the structure is more reasonable , but the surface is relatively thin, when easily damaged by the impact force; at the same time, due to the intermediate arrangement of four 23mmX15mm rectangular hollow structure, easy storage, at high temperatures, water vapor generated internally, could easily cause damage to wood flooring ; solid wood floor structure

Having a relatively high abrasion resistance, impact resistance, but consume more raw materials. So, when used, should be based on the actual situation, choose the appropriate section of wood flooring. In conclusion

1) Calculate the cross-sectional shape of the opening type wood floors can be ignored on both sides of the tongue and groove; when the hollow type and solid wood flooring type cross-sectional shape is calculated, can be ignored and the lower surface of the tongue and groove on both sides of the triangular groove.fence deck engineering wood

2) cross-sectional structure theoretically hollow wood flooring type is most reasonable. However, in actual use, the need to consider when choosing the specific circumstances.wpc planks prices

3) open type, approximate formulas hollow type and solid-section shape of computing, simplify the formula in practical applications.
