Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a new building structure, [which develops the traditional frame structure of a single-wooden house, and optionally incorporates panels with structural walls]. The purpose of the present invention is to provide a building having a wide and highly flexible interior and openings.

[Technology at the end of the sentence] Japanese houses have traditionally been constructed using wire rods.

It has the characteristic of consolidating the flow of power, and has the characteristic of consolidating the flow of power.
It is excellent in that it gives symbols such as beams and makes the building more attractive, and allows for the adoption of a fluid spatial configuration that adapts to the living conditions necessary for Japan's climate, such as sunlight and ventilation. .

[Problems to be solved by the invention] However, the above-mentioned buildings with frame structures were originally based on the use of a single large piece of material, and the ends of the pieces were fitted with joints that required a high level of skill. I needed to see the assembly.

In addition, modern frame-structured buildings are constructed using thinner materials and simple joints, partly because it has become impossible to obtain the large-scale materials and advanced techniques that were originally necessary. There is a tendency to use a lot of hardware, and the original Ramen-like strength and rigidity are lost, resulting in the need for #strength walls.
The advantages of the frame structure have been lost.

[Means for solving the problems] The present invention solves the problems of the above-mentioned tB construction animal structure,
This article concerns a new 115-piece structure that can be constructed at low cost and rationally.The main idea is to use straight laminated wood and to create vertical and horizontal joints with mortises and tenons. , 1 and 2 are joined by a pair of lower tension bolts to form a frame assembly with a 7 g rigid-frame structure with at least a substantially relaxed rigid connection, and in this case, as necessary. Accordingly, the required parts within the framework of the framework are composited with structural plywood panels.

The above-mentioned building structure of the present invention is mainly composed of a frame of rigidly connected rigid frame structure with substantially relaxed wood quality,
It is constructed by combining this with a load-bearing wall made of structural panels.

This rigidly bonded rigid frame structure that is substantially relaxed means a rigidly bonded frame structure that can be appropriately deformed to the extent that it can be restored due to the load applied to the building. In contrast to creating a rigid joint structure using hardware or using bracing etc. to create a rigid structure, the joint structure of the shiiguchi is made into a special structure and can be called a semi-rigid joint. This is what was done.

The rigid frame structure made of laminated wood in the present invention uses so-called straight laminated wood without bending, and the joint formed by a shallow mortise is rigidly joined using hardware (tension bolts) to soften the actual rigid joint state. The contact point in such a relaxed rigid joint state is naturally related to the deformation and strength of the building, and changes depending on the degree of deformation and strength of the building.

For the joint part made of laminated wood, for example, use a pillar made of laminated wood with a straight line 1 and a beam made of laminated wood with a straight line, and form a tenon between the two pieces in a shallower fit than usual. "(The -h of the beam material
Attach by carving a recess at the bottom and providing a bolt hole that passes through the column and into the recess marked E in the beam material, inserting the port into this bolt hole, and tightening both ends with nuts. It will be done.

In the rigid rigid frame structure formed as described above, it is desirable to use a material with a relatively large cross section as the laminated material.

The structure of the present invention uses a frame structure with relaxed rigid connections as described above, and does not require columns with braces or load-bearing walls in the internal space, and its vertical structure is placed on the outer periphery. I can concentrate. Furthermore, by reinforcing the relaxed frame structure at required portions within the frame with structural plywood panels, a building structure with even greater strength can be obtained.

For example, it is possible to form a long framework in the east-west direction, to have many openings on the south and north sides of the ridge, which are suitable for sunlight and ventilation, without using braces, and to use structural plywood panels only on the east and west sides.

Laminated wood is made by combining wooden planks parallel to the fiber direction and integrating the layers with synthetic resin adhesive. Structural plywood panels are used in wall construction methods and can be used as structural walls on their own. It is a composite board panel that can maintain the strength of

[Function] In general, the deformation of a building can be divided into deformation due to a load that is normally applied, and deformation due to a temporarily applied load (wind load, earthquake load).

Continuous loads include deformations such as deflection of beams, and deformations caused by wind loads and earthquake loads pose problems such as beams being pulled out, falling, and external walls collapsing.

The pillars and beams for conventional wooden A-frame structures are made of wood that has not undergone any special processing, and metal fittings called battledore bolts are also used to connect them, and many braces are installed at the required locations. We are dealing with deformation. This reduces the degree of freedom in openings and floor plans. In addition, a rigid rigid frame structure requires excessive hardware.

In addition to being more resistant to fire than conventional wood, the present invention has the following advantages: (1) less yield per ilu upon drying, and (2) overwhelmingly superior strength.

In particular, it can be reinforced and strengthened against local stress, (3
) Materials with large cross sections can be easily obtained. By using laminated timber, which has many advantages such as, compared to conventional construction methods, the strength is increased using only a small number of large straight timbers with a relatively large cross section, and the short tenons and the upper and lower pairs of Tension bolts are used in combination to create a stiff-jointed rigid frame structure that is relaxed, allowing the building structure to exhibit appropriate load followability.

In the short tenon structure described above, the adhesive of the laminated wood laminated with adhesive acts as a kind of hardening agent for the wood part, increasing the hardness of the wood material. As a result, the tenon portion is prevented from sinking in due to the load by 3J, ensuring appropriate flexibility against deformation.
In addition, a pair of separately provided tension bolts can prevent cracking and further strengthen the tightness of the joint.

In addition, in the present invention, the fitting depth of the tenons can be made shallower by impregnating and hardening the part of each laminated timber where the tenons fit with a synthetic resin to further improve the strength of this part. A mechanically effective cross section of the column can be economically secured.

In addition, by using the above-mentioned structural plywood panels, etc., which attenuate the deformation to some extent against large local deformations, it is possible to obtain a building structure that has sufficient strength and rigidity to withstand the various types of displacement described above. It can be done.
