A production method of a multi-glued reinforced column member having an improved compressive strength according to the present invention includes: a step of manufacturing a small diameter lumber having a square section in such a manner that a small diameter tree, which is a timber having a diameter of 18 cm or less, is prepared, both side surface of the timber are cut out respective to the center of the timber, after rotating the timer at 90 degrees, remaining both side surfaces of the timber are cut out to have a predetermined sectional dimension, the timber is dried to have a predetermined percentage of moisture content, and the dried timer is finished by a plane in order to remove contraction or twist; a step of manufacturing a large diameter lumber having a square section same as the section of the small diameter lumber in such a manner that a large diameter lumber having a diameter of 30 cm or more is prepared, four side surfaces of the large diameter lumber is cut out to have a predetermined sectional dimension, and the lumber is dried to have a predetermined percentage of moisture content and is finished by a plane in order to remove contraction or twist caused by drying; a step of jointing a plurality of manufactured small diameter lumber having a square section and manufactured least one large diameter lumber having a square section while making two layers vertically and transversely in a sectional plan and applying adhesive to each jointed surface; and a step of performing the sanding treatment to four outer side surfaces after performing the step of jointing. 본 발명에 따른 압축강도가 향상되는 다중접합 보강기둥부재의 제조방법은 지름 18cm이하의 간벌재인 소경목을 준비하고, 수심을 중심으로 양면을 제재한 후 90도 회전시켜 나머지 양면을 제재하여 일정 단면치수를 가지도록 한 다음 소정의 함수율까지 건조하고, 건조시 수축이나 뒤틀림을 제거하기 위해 대패 마감하여 단면이 정사각형인 소경각재를 제조하는 단계와, 지름 30cm이상의 대경목을 준비하고, 대경목의 4면을 제재하여 일정 단면치수를 가지도록 한 다음 소정의 함수율까지 건조하고, 건조시 수축이나 뒤틀림을 제거하기 위해 대패 마감하여 단면이 상기 소경각재와 일치되는 대경각재를 제조하는 단계와, 제조된 다수의 소경각재와 하나 이상의 대경각재를 포함하여 단면상에서 가로, 세로 각각 2중 이상으로 접합하되, 각 접합면에 접착제를 도포하여 접합하는 단계와, 상기 접합 단계 후 4개의 외측면을 샌딩처리하는 단계를 포함하여 이루어지는 것을 특징으로 한다.
