Abstract

PURPOSE:To effectively utilize thinning timber by providing the peripheral part of a reinforcing body lattice-likely assembled with a plurality of pieces of thinning timber in a frame body composed of pillars and beames of wooden framework through pin jointing or rigid jointing. CONSTITUTION:A reinforcing frame 2 is constituted out of a plurality of pieces of thinning timber assembled lattice-likely or diaper-likely, and the crossing parts are fixed by nailing, bolting, or adhering. A frame body 6 is constituted out of pillars 4 and beams 5, or beams 5 and beams 5 of wooden framework. The reinforcing frame 2 is built in the frame body 6, and both ends of the thinning timber are pin-jointed or rigidly jointed with the pillars 4 or the beams 5.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a wooden framework that makes it possible not only to use general large-section laminated timber and materials, but also to make effective use of thinned timber that has hitherto been neglected. be.

[Conventional technology]

In general, wood is easy to process, lightweight, comes in many varieties, and is relatively economical, so it has been widely used to this day.

On the other hand, it has the disadvantage that the strength of the joint is extremely weak compared to steel frame materials because it is necessary to cut out a considerable amount of the joint.

For this reason, it is necessary to compensate for the decrease in strength due to this cross-sectional defect by reinforcing the joint with special hardware or using a larger member.

Furthermore, although reinforcements are generally installed on walls and beams in many cases, there is a drawback in that openings cannot be provided in areas where there are reinforcements.

In addition, since misalignment has the property of causing brittle fracture, there is also the drawback that it is difficult to grasp the destructive nature of the entire frame.

By the way, the current situation is that the large amount of thinned wood that is generated during logging is left unused in mountain forests all over the country because no use can be found for it.Currently, as the protection and effective use of forest resources is called for, how to dispose of it is an issue. It has become.

Therefore, if this thinned wood could be used for wooden buildings,
Waste of forest resources can be avoided.

This invention was proposed in view of these circumstances.
The object of the present invention is to provide a wooden framework that makes it possible to effectively utilize thinned wood in addition to commonly used wooden structural members.

[Means to solve the problem]

This invention provides a reinforcing frame constructed by combining a plurality of thinned timbers in a lattice shape or plate shape in a bridge body constructed of wooden frame columns and beams or beams and beams. The above object is achieved by having a configuration in which the pillar or beam is pin-joined or rigidly joined.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a description will be given based on an embodiment illustrating a wooden frame according to the present invention.

A reinforcing frame 2 is constructed by stacking multiple pieces of thinned wood 1.1 in a grid or diamond pattern and nailing, bolting or gluing the intersections together (see Figure 6). It is also possible to provide a notch at the intersection of the materials 1 and 1.

The reinforcing frame 2 is made of thinned wood 1. . . are formed into shapes as shown in FIGS. 1 to 3, for example.

Figure 4 shows the cutting of multiple trees with so-called chamfering 1.・・・
A reinforcing frame 2 constituted by integrally connecting two laminated panels 3 in the width direction, and integrally overlapping these laminated panels 3.3 at right angles.
This is what is shown.

Further, FIG. 5 shows a reinforcing frame 2 constructed by integrally stacking an assembled panel 3 on the back side of the reinforcing frame 2 shown in FIG. 3.

The reinforcing frame 2 constructed in this way has wooden frame columns 4.
and the beam 5 or the beam 5 and the beam 5, and both ends of each thinning material 1.1 are pin-joined or rigidly connected to the column 4 or the beam 5 of the bridge body 6. has been done.

Considering the case where a horizontal force P acts on the frame body 6 in such a configuration, when the frame body 6 resists the horizontal force P and tries to maintain its original rectangular shape, the pillars 4 and If the reinforcing frame 2 is connected to the beam 5 in a pin-jointed state, a bending moment will be generated only at the joint portion of the reinforcing frame 2, but this allows sufficient resistance to the horizontal force P.

Furthermore, when a large horizontal force is received due to an earthquake or the like, the horizontal force is mainly borne by the reinforcing frame 2 (the joints of the reinforcing panels).

Further, when the reinforcing frame 2 is damaged due to excessive horizontal force, only the damaged reinforcing frame 2 is replaced.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

It is now possible to effectively utilize thinned wood that was previously left at logging sites, allowing for effective use of forest resources.

Furthermore, by using a reinforcing frame instead of using braces, the horizontal rigidity of the wooden framework can be increased to a level equal to or greater than that of braces.

In addition, since there are no misalignment lines, openings can be freely created in walls and floors.
