Description

[Detailed description of the invention] This invention relates to a wooden beam material that can be used as a beam for residential construction, etc.

・In the case of a single-planted artificial forest, thinning is required during the growth stage.

By the way, this thinned wood has a diameter of about 8 to 10 cm,
When it is sawn, it becomes about 7 cm square, which is often inconvenient as a structural material for buildings depending on the conventional structure.

This invention is an example of a device developed to enable the use of inexpensive thinned wood with a small cross section as a construction material, and its details will be explained below with reference to illustrated embodiments.

A wooden building implementing this idea uses lumber sawn into 7 cm squares for pillars, girders, etc., and combines these with face materials such as plywood to construct walls.

By the way, if you need a beam, you cannot use a single piece of 7cm square wood.

Therefore, the above-mentioned 7 cm square wood is cut in half and combined with plate materials such as plywood to form a combination beam.

This beam material 1 has the following configuration.

In other words, two side corner pieces of wood having the same cross section are used as the upper chord member 2 and the lower chord member 3, and the bundle members 4 are arranged at a required interval and connected vertically, and the space between the upper chord member 9 and the lower chord member 3 is made of plywood on the side. By pasting plate materials 5 made of boards etc., they are connected to form a unit beam material, and the unit beam materials are arranged in parallel, and the plate materials 5,
The parts 5 facing each other are made of square wood, and are assembled by being connected back-to-back through intervening members 6 arranged vertically at required intervals.

It is preferable to lift the unit beams individually and assemble them at the installation site during erection.

When installing this beam member 1, the bundle members 4 and the lower chord member 3 at the end are provided so as to protrude from the upper chord member 2, and the lower chord member 3 is erected on the lower stringer member 7 of the upper and lower stringers arranged in two stages. The upper stringer member 8 of the stringer member is configured to be in the same plane as the upper chord member 2.

In addition, when the floorboards 9 are to be laid, square wood joists 10 are installed at predetermined intervals on the beams 1 and the upper girders 8.

In addition, the code 11 is a column, and this column 11 is the upper and lower girder members 7,
8 may be covered with plywood or the like that forms the wall surface.

In addition, by extending the intervening material 6 upward for the required length, the main building 12 and the ridgepole 1 are installed.
3 can be attached, and the intervening member 6 can be extended downward as required to support the lintel 14 and the like.

This idea consists of the above-mentioned structure, and by arranging two pieces of 7cm square wood in parallel and above each other and connecting and assembling them with plates such as plywood, it is possible to construct a unit beam with considerable strength. By combining unit beam members arranged at required intervals and interposed in the longitudinal direction, cross-sectional performance with respect to the vertical axis of the beam can be improved and lateral deflection can be reduced.

Furthermore, the interposer can extend upwardly or downwardly to allow the attachment of purlins, cuttings or lintels.

Claims (1)

[Scope of utility model registration request] The top and bottom chords are made of squarely split wood, and are connected vertically with bundles arranged at required intervals, and the upper and lower chords are connected by pasting plates on their sides to form a unit beam. What is claimed is: 1. A beam material, characterized in that the unit beam materials are arranged in parallel, the plates are facing each other, and are connected back-to-back through longitudinal intervening members arranged at required intervals.
