选择胶合板主要看其甲醛释放量和胶合强度。如果胶合板的胶合强度不好,容易散架。选择时注意胶合板的标称厚度与实际厚度是否相符。
The choice of plywood mainly depends on its formaldehyde emission and bonding strength. If the gluing strength of plywood is not good, it is easy to fall apart. When choosing, pay attention to whether the nominal thickness of plywood is in line with the actual thickness.
H型钢是一种断面力学性能较工字钢优良的经济型断面钢材,因其断面的形状与英文字母“H”相同而得名。热轧H型钢的翼缘比工字钢宽、侧向刚度大、抗弯能力强。同等规格下H型钢理重较工字钢轻。
H steel is a kind of economical section steel with better section mechanical properties than that of I-steel. Because the shape of the section is the same as that of the English letter 'H'. The flange of hot rolled H steel is wider than that of I-steel, large lateral stiffness and strong bending resistance. Under the same specification, the weight of H steel is lighter than that of I-steel.
