Description

Detailed Description of the Invention (Field of Application of Industry-1-) The present invention relates to NIT hardware for wooden buildings, and in particular, to pillars,
This invention relates to hardware used as a joint when tightening frameworks of structural materials such as horizontal members and braces.

(Prior Art) Conventionally, the metal fittings used in the framework of wooden buildings are reinforcing metal fittings that strengthen joints of structural members and joints. This reinforcing hardware is, for example, flat hardware, short hardware, bracing hardware, battledore bolt hardware, etc., and after carving joints such as large mortises for columns and beams or body differences at the processing factory, they are used at the construction site. The building is then brought in and erected, and then reinforcing hardware is applied to the outside of the pillars and girders, and these are attached with slanted nails, bolts, etc.

(Problem to be Solved by the Invention) However, in conventional hardware, since it is applied to the outer surface of the joint part of the structural material, it is deviated from the core of the material.
For example, when a horizontal external force is applied to a building and a pulling force is applied to a column, the column twists and rotates, and there is a risk that the carved joints will be damaged and detached.

Furthermore, the hardware used is an auxiliary one, and does not omit the carving of the frame joints (also, since many nails are driven, construction is time-consuming.

Furthermore, in order to obtain the necessary frame strength, it is necessary to use a large number of metal fittings, which increases the cost.

Furthermore, the exterior wall base materials had many problems, including the difficulty of nailing them together due to the hardware attached to the exterior surface.

The metal fittings of the present invention are housed in one structural member to be joined, and the metal plate secured with a pin is fastened with a bolt that passes through the other structural member, and this joint part is further connected to beams and reinforcements. Even if a large number of defects are to be joined, the metal plate should be added so that it is exposed on the inner surface of the column or the bottom surface of the beam without protruding from the outer surface of the wall of the structural material. Therefore, there is no problem in attaching the outer wall base material of the structural material, and the hardware is used as the joint itself, and no twisting or rotation phenomena occur due to external force. Furthermore, fewer pieces of hardware are used,
It is an object of the present invention to provide a metal fitting that can be used for frame construction with an extremely small number of nails and labor-saving. is a vertically elongated rectangular metal plate with a column width, and a bolt insertion cylinder is provided vertically inward from the center of one of the upper and lower edges of the column, and
A nut screw hole 11110 is provided from the inner end of the cylindrical body, and at least two pin holes are provided in the metal plate at desired positions with a desired spacing of 1 inch.

Then, a cylindrical body is interposed at the tip end of the bolt that penetrates the horizontal member at a predetermined position, and a nut is screwed and tightened from the opening portion to fix the metal plate upright along the axial direction of the horizontal member. This metal plate is fitted with a slit-shaped groove cut in the axial direction from the end of the column and a cylindrical hole, and a pin is inserted through the pin hole from a predetermined position of the column in a direction perpendicular to the metal plate. Arrange and fasten the pillars.

After joining the horizontal beams, which are horizontal members, to the columns with hardware, when creating a complex framework by joining beams and multiple braces, attach an L-shaped or L-shaped upright part to the metal plate downward. Provide the extended support plate mounting metal plate and secure it tightly.

Furthermore, when the mounting metal plate is large in size, the mounting metal plate is arranged so as to be sandwiched between the support and the horizontal member, and the mounting metal plate is attached to a base plate that is locked to the metal plate to form a hardware that can be disassembled and reassembled. do.

(Function) Regarding the joints of structural materials constructed using the hardware of the present invention, the various joint structures are standardized, and all processing is done using mechanically operated saws and drills in the factory, and each floor plan of the building is The drawings, the position codes on the internal and external wall framework drawings, and the standard model numbers of the structural materials are brought to the site, and at the construction site they are simply and easily joined using the corresponding type of hardware. It is possible to assemble strong, high-quality wooden buildings.

In the hardware of the present invention, the core of the column and the horizontal member are joined, so that it does not twist and rotate even if a pulling force is generated when a horizontal external force such as an earthquake is applied to the structural member.

In addition, the structure and strength of joint joints of structural members framed using the hardware of the present invention are greatly increased by the mutual synergistic effect between the hardware, and in particular, the joints are formed in multiple directions consisting of columns, horizontal members, and braces. It works particularly effectively as a connecting material of the size of a tiger.

In addition, the number of pieces of metal fittings used in a building according to the present invention is much labor-saving compared to conventional reinforcing metal fittings, and the joining work is simple, reducing the number of nails and labor required, which greatly reduces construction costs. works to reduce

(Example) Examples will be described with reference to the drawings.
