[0002]

[Prior art]

 Conventionally, this kind of thing is as follows. In recent years, the structural materials used for wooden construction have changed to general lumber, and structural laminated wood and laminated veneer lumber are used. Recently, many wooden construction methods with large cross sections and large spans have been constructed. Due to the decrease in imports of general lumber products due to global forest protection measures, soaring prices, and soaring labor costs due to a shortage of craftsmen (carpenters), it has been recommended to develop construction methods that are rationalized and industrialized for wooden construction. However, the current situation is that the development of joint hardware has been delayed accordingly.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. Problems with conventional beam receivers A. Beam receiving hardware in conventional construction method Since a large force (bending, shearing, tension) is applied to one point at the joint between the column and the beam, highly reliable hardware is required. Since bolts and nails are used together to secure the structure, the structural yield strength is unreliable and it cannot be used for large-section / span construction methods. Workability is poor because it is necessary to attach a metal object and pull the beam with a battledore bolt.

B. Large-section beam receivers Many large-section beam receivers do not receive anything at the bottom of the beam, and are loaded only by the shearing force of the hardware mounting bolt. Since the wood touch that pulls the beam to the column is not considered, there is a risk of breaking when a large force is applied because it is set only by the shearing force with the bolt that holds the beam. C. For shrinking / loosening of wood due to drying, and for joining iron and wood, spring washers are used to prevent loosening of mounting nuts due to drying of wood. I can't handle it.

The present application has been made in view of such problems of the conventional technique, and an object of the present application is to provide the following things. In other words, in recent years, it has been widely used in homes and medium-scale construction, structural laminated wood, buildings made of structural wood produced by factory processing such as laminated veneer lumber (LVL), and well-dried general lumber. The purpose of the present invention is to provide a joint metal structure that is inexpensive, has good workability, shortens the construction period, and is safe and has sufficient structural strength for buildings for structural materials.

The shape of the wood touch hole 31B2 is a flat round shape if the wood touch stick is a pipe / round steel, and a flat square shape if it is a plate.

In addition, a cutout portion 31B3 is formed at the end of the beam by pre-cutting by the flange width to allow the length of the bolt to escape. Further, a beam fixing bolt hole 31B4 and a wood touch confirmation pin hole 31B5 are provided.

The device of the present invention operates as follows. 1. Referring to FIGS. 6 and 7, when the beam is dropped from the upper side to the lower side of the beam receiving member main body attached to the column with bolts, the beam is pulled toward the column side, which is a so-called wood touch. 2. Since the beam receiving hardware body has a flange for receiving the beam, the load received by the beam can be safely transmitted to the column. At this time, the flange can be extended longer than the wood touch stick, and the load distribution can be taken into consideration for further safety.

3. The beams can be used for all types of wooden beams such as structural laminated wood, LVL, box beams, and general lumber. 4. In addition to the beam fixing bolt hole, a wood touch confirmation pin hole is provided, so it can be confirmed by driving a pin into the hole with a wooden beam. The workability is improved by considering that it can be temporarily fixed with a wood touch confirmation pin so that the beam bolting work can be done later during erection.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the case of the beam receiving structure 1, 1. It can be easily manufactured at the factory by welding the web plate with the wood touch stick welded to the L-shaped flange. 2. By changing the thickness of the plate, the flange, the size of the web plate, etc., it is possible to deal with relatively large-scale buildings (large span, large section). 3. By using a corrugated cover plate that has been corrugated by a press machine and fixing it with a special nut, the spring washer can be omitted, and the joint becomes stronger (prevents loosening).

[0028] 4. It can be manufactured at low cost, and further cost reduction can be achieved by mass production. 5. By providing slits and holes for wood touch on the beams, there is no need for special marking, cutting, or processing, unlike the conventional method. 6. The plate on the pillar side of the L-shaped flange is wave-processed before bending, and the column mounting bolt holes are opened, so that the wave cover plate when beams are attached to both sides of the pillar can be used even when it cannot be used. The same effect can be obtained, and the bolt head can be tapered to prevent loosening on both sides as shown in the figure.

In the case of the beam receiving structure 11, 1. The web plate 51 needs only a planar U-shaped bending process with a press machine, and only the flange needs to be welded, which facilitates mass production. 2. Since the load is applied by using two web plates, the overall plate thickness can be designed to be thin, and the weight can be reduced. 3. Since it is formed by press working, it is suitable for houses and small-scale buildings. 4. Mass production is possible, and inexpensive hardware can be provided.
