Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of connecting timbers using rejoint metal fittings.

[Prior art] When connecting and assembling the wood materials used to make wooden desks, chairs, sheds, shelves, pallets, etc., one way to connect the wood is to connect the wood in a T-shape or L-shape. There is a method of connecting two pieces of wood to be connected by using a joint metal fitting and attaching the joint metal fitting to the connecting part of the pieces of wood to be connected using nails or bolts.

[Problems to be Solved by the Invention] According to the above-mentioned conventional method for connecting wood, the pieces of wood to be connected are temporarily fixed in the form to be connected, for example, by hand, and a joint hardware is attached to the connection part. There are problems in that the work is cumbersome because it is attached with nails or bolts, and the connection part is not sufficiently solid.

The present invention relates to a method for connecting wood with the purpose of solving the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention forms grooves in each piece of wood to be connected, and on the other hand, grooves are formed in each piece of wood to be connected in a T-shape,
Form an insertion piece to be inserted into a groove formed in each of the pieces of wood to be connected to the joint hardware formed in an L-shape or other appropriate shape, and insert the insertion piece of the joint metal piece into each groove of each piece of wood to be connected. The joint hardware was inserted and nailed or bolted to each piece of wood.

[Function] By inserting the insertion piece of the joint hardware into the groove of each piece of wood that is aligned with the predetermined connection form, the wood is first temporarily fixed in the connection form, and in this state, the wood and the joint hardware are connected to each other in the y-island. The pieces of wood are connected and fixed by attaching them with nails or bolts. In addition, the insert piece formed on the joint hardware becomes a rib and gives strength to the joint hardware, so that the pieces of wood connected by this joint metal piece are firmly connected and fixed, and the pieces of wood connected by the insert pieces are prevented from shifting. Prevented.

[Example] Hereinafter, an example of the method for connecting wood according to the present invention will be described in detail with reference to the drawings.

In the method for connecting timbers according to the present invention, first a groove 2.2' is formed in each timber 1.1. There are no particular limitations on where these grooves 2, 2' are formed, but
In the embodiment shown in the drawings, a groove 2.2' is formed in the center of one side of the wood 1, 1' in the longitudinal direction. The groove width of the y4 portions 2, 2' is formed to be wide enough to allow insertion of an insertion piece formed on a joint hardware, which will be described later. Further, for the groove portion 2.2' formed in the wood 1.1, a back split formed to prevent cracking of the wood may be used as the groove portion.

A joint hardware 3 is used to connect the timbers 1 and 1', and this joint hardware 3 has the following features:
The board 4 is formed in a shape having mounting portions 5 and 5' in an L-shape direction, a T-shape direction, and other directions depending on the connection form, and this shape is not particularly limited, including the shape of well-known joint hardware. In such a joint metal fitting 3, each groove 2. in the vicinity of the connection part of the wood l, 1' to be connected.
Insertion pieces 6, 6 are formed to be inserted into 2'. The width of the insertion pieces 6, 6' is at least equal to or less than the depth of the grooves 2, 2'. 7, 7 is the mounting part 5.5'
This is the nail hole formed in the hole.

Using the joint hardware 3 made of 4R, match the pieces of wood 1 and 1' to be connected according to the connection form, and then insert grooves 2 and 2' of the pieces of wood 1 and 1' according to the connection form. Insert the insertion pieces 6, 6' of the joint hardware 3 into the mounting parts 5, 5 of the joint hardware 3, respectively.
′ against the surface of the timbers 1 and 1′ and secure with nails or bolts.

According to this method of connecting timbers, the grooves 2.2 of each timber 1.
By inserting the insertion piece 6°6' of the joint hardware 3 into ', the pieces of wood l and 1' are temporarily fixed to the connection form fE. In this state, wood 1.1 and joint hardware 3
By attaching +) - with nails or bolts, wood 1
．． 1 is connected.

In addition, the insertion pieces 6.6 formed on the joint hardware 3 serve as ribs and give strength to the joint hardware 3, so that the pieces of wood l and 1' connected by the joint hardware 3 are more firmly connected and fixed. At the same time, the insertion pieces 6, 6 inserted into the grooves 2.2 prevent the connected pieces of wood 1.1 from shifting relative to each other.

[Release]! [Effect 1] As described above, according to the method for connecting lumber according to the present invention, grooves are formed in each lumber to be connected, and grooves are formed in T-shape, L-shape, or other appropriate shapes depending on the connection form of crystal lumber. The joint hardware is formed with an insert piece that is inserted into the groove of each wood to be connected, and the insert piece of the joint hardware is inserted into the groove of each wood to be connected, and the joint hardware is nailed to each wood. Since the pieces of wood to be connected are fastened or bolted together, the pieces of wood to be connected are first temporarily fixed in the connected form by inserting the joint metal fittings, and in this state the wood and the joint metal fittings are fastened together with nails or bolts. This makes it possible to easily and reliably connect each piece of wood using the joint hardware, and the insertion pieces formed on the joint hardware serve as ribs to give strength to the joint hardware, allowing each piece of wood to be connected easily and reliably. This has the effect that the pieces can be more firmly connected and fixed, and furthermore, the inserted pieces inserted into the grooves of each piece of wood can prevent the pieces of wood connected from shifting from each other.
