JPH1110610A - Reinforcing material-filled glued laminated timber - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a glued laminated timber having more rigidity than that of a steel frame by sandwiching together reinforcing material such as carbon fiber and spacer between laminated wood chips, and adhering it with adhesive material, thereby increasing its strength. SOLUTION: A reinforcing material 2 such as carbon fiber and spacer are sandwiched between longitudinal, lateral, obliquely or partly wound at wood chips 1 to match using sites of glued laminated timers, and laminated with adhesive. And, the material 2 is sandwiched between the surfaces of the timbers so as not to protrude from the timbers. Thus, the using site is selected by a way of inserting the material 2 such as the fiber between the chips 1 used for the timbers. At the time of using it for a post, the material 2 is inserted longitudinally, laterally, obliquely or windingly so as to endure against a force such as warp or twist. At the time of using it for a beam, the material 2 is inserted much longitudinally, and partly windingly so as to endure a load from above. And, the spacer having the same thickness as the material 2 is sandwiched therebetween to eliminate a gap in the timber.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated timber for construction having a reinforcing material therein.

[0002]

2. Description of the Related Art Conventionally, modified woods are provided with mating joints at both ends of a piece of wood, which are glued together with an adhesive to produce laminated wood suitable for the purpose. This piece of wood may have insufficient strength due to the use of thinned wood or miscellaneous wood, and long span beams require thick pillars for wood.

[0003]

The conventional laminated wood uses a piece of wood having a low strength, so that the strength may be insufficient. Furthermore, since the rigidity of the steel frame is insufficient, it is intended to provide a laminated wood having a strength higher than that of the conventional wood and a rigidity higher than that of the steel frame.

Means for Solving the Problems In order to achieve the above-mentioned object, means for sandwiching a reinforcing material 2 such as carbon fiber and a spacer 3 together between pieces of wood 1 to be bonded and bonding them with an adhesive 4 are provided. It is.

[0005]

According to the present invention, the above measures are taken. When using this method, depending on how to assemble the wood pieces 1 and how to insert the reinforcing material 2,
Choose between pillars and beams.

[0006]

Embodiments will be described with reference to the drawings.
In FIG. 1, a reinforcing material 2 such as carbon fiber and a spacer 3 are sandwiched between the wood pieces 1 vertically or horizontally and further diagonally or partially in accordance with the use area of the glued wood, and they are glued together with an adhesive 4. It is also effective to insert the reinforcing member 2 so that it does not come out on the surface of.

[0007]

Since the present invention is configured as described above, the following effects can be obtained.
The site to be used is selected according to how to insert the reinforcing material 2 such as carbon fiber between the wood pieces 1 used for the laminated wood. When using for pillars,
In order to withstand the torsion, kinking, etc., put the reinforcing material 2 upright and diagonally and further roll it. Also, when using it for the beam, put the reinforcing material 2 in the vertical direction and roll it partly more appropriately. It becomes a beam that can withstand the load. In addition, since a spacer 3 having the same thickness as the reinforcing material 2 is interposed, no gap is formed inside the laminated wood. Further, since the black color of the reinforcing material 2 such as carbon fiber does not appear on the surface, a laminated wood excellent in design can be obtained. Furthermore, by sandwiching carbon fiber, which is stronger than iron, into rigid wood, it becomes a building material that is stronger than steel and has the rigidity of wood.
In addition, during the present time when the number of trees that become timber is reduced in order to prevent natural destruction, the present invention provides a method of manufacturing laminated timber that is advantageous for the reuse of logging and waste materials.
