Description

The present invention relates to a construction method of a ramen structure using a direct-glued laminated lumber.

The conventional ramen structure using the direct-glued timber by the moment resistance jointing method of the column and beam of the wooden structure is mainly a large cross-sectional structure, and there is a portal ramen and a Yamagata ramen. A shaft with a small cross-sectional structure has problems of joint strength and fire resistance, and it has not been popular in Japan, but in recent years it has been used in wooden houses, etc. in combination with the conventional shaft method and 2 × 4 method. Noodles with bearing walls have been popularized.

The frame structure of the ramen structure using straight-glued timber is 1 1-way ramen, 2-way ramen 2 portal ramen, continuous beam ramen 3 There are column win method and beam winch method, etc.

The joints of the ramen structure using direct-glued laminated lumber include 1 steel plate-attached plate type joint 2 mating beam + shear fastener type joint 3 tension bolt type joint 4 special bar steel insert type joint 5 steel plate insert joint

The ramen structure using the direct-glued laminated material to be solved has the following problems in the large-section ramen and the bearing wall ramen.

Problems with ramen-structured joints using conventional straight-laminated timber.
1 A large joint connection hardware such as an insertion plate for beam connection or an insertion bar is required at the stigma.
2 It is necessary to insert joint connection hardware into pillars and beams, and to make holes for bolts and drift pins for fixing.
3. Inserting plate or steel bar is inserted into the beam joint at the column head and fixed with bolts, lag screw screws, drift pins, etc. The problem is that the initial stress is low.
4 The joints of wooden ramen columns and beams become vertical joints between the fiber direction and the radial or tangential direction due to the anisotropy of wood, and the indentation stress can only be generated by 1/10 of the shear stress.
5 The allowable stress of wooden ramen depends on the accuracy of the fitting and the precut accuracy of the wood.
6 Large-scale hardware for fastening the foundation is used for the connection between the column base and the foundation.
7 Continuous beam ramen construction is difficult.

Problems such as construction 1 Like the steel frame ramen, it is not possible to build a pillar.
2 Since the columns and beams are temporarily assembled at the time of site construction, workability is poor and time-consuming at small sites.
3 The cross-sectional defect of the beam joint in the beam direction occurs in the span direction ramen.
4-digit beam joints can be either user factory processing or on-site hardware construction.

In order to solve the problems as described above, the present invention eliminates the hardware construction method using bolts and drift pins. The head of the ramen column is cut into a seam and processed. [Figures 1 and 2]
2. For the column head of the ramen column, the fitting part of the bracket is cut into a fastener and is actually processed, and the beam joint is processed on the beam joint side. [Fig. 3, 4, 5]
There are the following types of beam joints.
Japanese traditional joint A, basic form: butting, phase missing, killing, wrong eye, ant, sickle, almost sickle, spear, chair, box, etc.
B, depending on specification and use: Sitting dovetail, sitting sickle joint, misplaced sickle joint, large carrying joint, follow-up large plug joint, metal ring joint, buttocks joint joint, etc. You can inherit wood without any problems. The beam joint of the present invention uses a joint that is actually processed as a killing joint.
3. Apply adhesive to the head end of the ramen pillar.
4). Attach the bracket end to the stigma end of the ramen pillar, and drive nails into the actual part from the side to form the core part of the pillar and bracket.
The nails include round nails and thick nails. The effect is the same even if screws are used.
5). Adhesive plates with adhesive applied to the ramen pillars, stigma and bracket cores are fixed by driving nails from both sides, and the stigma and brackets are reinforced with rectangular or flat metal parts. [Figs. 6 and 7]
Examples of the attachment plate include a steel plate, a structural plywood, and an attachment plate in which aramid fibers are attached to the structural plywood.
6). A donated object is provided on the upper and lower surfaces of the above-mentioned ramen pillar and bracket. [Figs. 6 and 7]
The attracting hardware may be provided at the construction site.
7). A donation will be provided at the base of the ramen pillar block pillar. [Figs. 8 and 9]
