Problems solved by technology

If low-quality wood is used, it will cause discontinuity or damage to the structure of the profile, causing the profile to lose its due use value
Due to various reasons, some log materials are more or less flawed, so the profile processed from the log material is affected by the flaws, and considering the anisotropy of the wood, its yield is low, resulting in wood defects. waste
Therefore, the problems of wasting a large amount of log materials such as overuse of high-quality materials and inferior use of high-quality materials often occur.
In addition, some deformed and bent log materials have a low yield, and the deformation of the profiles due to improper storage or use or the waste profiles used on site are also the main reasons for the waste of wood.

Embodiment Construction

[0011] The specific structure of the present invention will be described in detail according to Figs. 1-3. The cross-section of the spliced ​​profile is I-shaped, and it includes an upper panel 1, a lower panel 3 and ribs 2 clamped therebetween, and its specifications and models should be determined according to commonly used profiles in construction engineering. Generally, the cross-section specifications of common profiles are (40-60mm)×(60-90mm), and the lengths are different. Among them, the upper panel 1 and the lower panel 3 are composed of finger-joint plates made of general technology, and the rib plate 2 clamped between the upper and lower panels 1 and 3 is assembled by at least three layers of finger-joint plates made of general technology. become. The specification, size and model of each finger joint board can be selected according to the needs and possibility, and its thickness is not limited, but it should be between 10-18mm. Its width should be selected accord...

Abstract

The invention relates to an I-shaped wood. Wherein, said assemble section is formed by upper and lower panels and inter rib plate, whose section is I-shaped. And the invention is characterized in that: the upper and lower panels clamp the rib plate that formed by at least three layers of finger assemble plates; the seams between them are alternated. The invention can eliminate the defect of former wood on the processed section, to improve the wood utilization and reduce cost.

Description

technical field [0001] The invention relates to a spliced ​​profile used in construction engineering, in particular to a finger-jointed board combined I-shaped wood integrated with spliced ​​boards. The spliced ​​profile can replace the solid wood profile to meet the needs of various construction projects. Background technique [0002] At present, the physical and mechanical properties required for wood materials used in construction projects are relatively high, especially for formwork components and supporting wooden squares. The board surface is not allowed to have defects such as cracks, knots, oblique seams, wormholes, and decayed surfaces. , for which a large amount of log material is consumed. If low-quality wood is used, it will cause discontinuity or damage to the structure of the profile, causing the profile to lose its due use value. Due to various reasons, some log materials are more or less flawed, so the profile processed from the log material is affected by ...
