Abstract:
PURPOSE: A strength reinforcement type wooden guardrail is provided to reduce damage occurrence from an external impact, and easily implement installation and replacement. CONSTITUTION: A strength reinforcement type wooden guardrail includes a wooden post(10), a wooden rail(20), a metal connecting block(30), and a reinforcement beam(40). The wooden post(10) is vertically erected. The wooden rail(20) is horizontally supported and is installed on the wooden rail(20). The wooden rail(20) includes a hollow(21), numbers of first and second fastening bolts(15,16), and bolt holes(25,26). The hollow(21) is formed in a length direction inside the wooden rail(20). The wooden post(10) is fastened with the wooden rail(20) by the numbers of first and second fastening bolts(15,16). The bolt holes(25,26) are penetrated by the numbers of first and second fastening bolts(15,16). The metal connecting block(30) is coupled to the wooden rail(20), and is placed in response to the wooden post(10). The metal connecting block(30) is connected to the wooden post(10) by the numbers of fastening bolts(15). The reinforcement beam(40) is inserted into the hollow(21) of the wooden rail(20).
Abstract:
본 발명은 대단면 목재에 중공을 성형하는 단계, 및 중공 처리된 대단면재 재료를 열기 건조하는 대단면재 건조방법에 있어서, 중공 처리된 대단면재 외면에 수분 탈출방지수단을 제공하는 단계를 더욱 포함하는, 중공목재 건조방법에 관한 것이고, 상기 수분탈출방지수단을 부가함으로써 수분의 외부 표면으로 증발되는 것이 억제되고 중공 안쪽으로 수분이 증발되므로 건조결함인 할렬 발생을 억제할 수 있고, 건조속도가 우수한 기술적 효과를 달성할 수 있다.
