Abstract

<P>PROBLEM TO BE SOLVED: To provide a wooden portal type rigid frame capable of handling bending moment and tensile force by a shaft and handling shearing force by a column. <P>SOLUTION: The bending moment and tensile force of the wooden portal type rigid frame can be transmitted by the shaft, and the shearing force by a capital, so that clear structural calculation divided into bending moment and shearing force can be made in the same way as a rigid frame structure such as a steel structure. Further, since the required number of wooden portal rigid frames can be used for required parts and constructed at a part of a wooden framework method in combination with the wooden frame work method, a mixed structure is provided at a lower cost in comparison with a mixed structure with steel construction or reinforced concrete construction. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a moment resistance joint between a column and a beam of a wooden frame.

In the conventional wooden structure frame column and beam moment resistance joint joint method, large cross-section structure is mainstream, and small cross-section structure for wooden houses has problems of joint strength and fire resistance Japan Is almost unpopular

The wooden gate type ramen frame joint has 1 gusset nail processing joint type with LVL plate 2 wood panel construction method 3 frame wall construction method 4 tension bolt type, etc.

Problems to be solved include the following problems even in the wooden gate type ramen frame method with a large cross-sectional structure

  For gusseted nail processing joining with LVL plate and wood panel construction method and frame wall construction method type, allowable stress is determined by the strength of the nail in the performance test etc., so there is no variation due to wood destruction, so the variation coefficient becomes low and high strength value comes out Considering the shrinkage and deterioration of nails and wood after 10 to 15 years due to storm stress, the allowable stress is low and it is quite dangerous at the time of earthquake

The tension bolt joint type is a construction method in which bolts and lug screws are joined, but there is a temporary material for receiving the beam at the time of construction, and hardware is also externally attached, so that the fire resistance performance is lowered and the workability is also poor.

In order to solve the above problems, in the present invention, a wooden gate type ramen construction method in which a shaft is provided at a joint between a pillar and a beam of a wooden structure and a moment resistance joint is applied to the heads and pillars of a plurality of pillars. Set a shaft to handle the bending moment and tensile force, set the beam on the head shaft, fasten it with drift pins and bolts, fix the shaft with base plate to the column base, and connect the anchor bolt to the foundation A wooden gate-type frame frame that is tightly connected to the foundation, which bears vertical stresses such as fixed loads and load loads and horizontal stresses such as earthquakes and storms.

When the wooden gate-type frame frame of the present invention is used as a frame of a wooden house, a narrow-edge house or a long-span wooden house can be constructed.

The wooden gate type ramen of the present invention can process the bending moment and tensile force with the shaft and the shearing force with the stigma, so the size of the member can be calculated by structural calculation and the joint hardware is also set inside the wood, so the fire resistance of the joint hardware Expect performance

A shaft hole for setting the shaft perpendicular to the top of the pillar and a hole for the drift pin for fixing the shaft are provided horizontally, the shaft is inserted into the shaft hole, and the drift pin is driven into the hole for the drift pin. Fix the shaft to the stigma and set the beam with the vertical hole for the shaft to set the shaft at the end and the horizontal hole for the drift pin to fix the shaft to the shaft of the stigma. Fix the column head and beam end, and then tighten the bolt with the washer set on the shaft's internal thread from the beam shaft hole. The same effect can be obtained by installing a pin fixing groove and a female screw for setting the bolt, or fixing with a bolt and nut instead of a drift pin for fixing the shaft. It is

The column base is provided with a shaft hole for setting the shaft vertically and a drift pin hole for fixing the shaft horizontally, and the shaft portion of the shaft with the base plate is inserted and set in the shaft hole. Insert the drift pin into the hole for the drift pin, fix the shaft with the base plate to the column base, and then fix the base plate part to the anchor bolt of the foundation with a washer and nut and tighten the column base to the foundation. A groove that can fix the pin and a female screw for bolt connection are provided, and a hole for fixing the bolt and anchor bolt is provided in the base, and the base plate is set on the shaft with a bolt. The same effect is produced even if the shaft is fixed by welding etc.

1 to 3 show a shaft hole for setting the shaft at the head of the column and a drift pin hole for fixing the shaft, and the shaft is inserted into the shaft hole and the drift pin is inserted into the drift pin hole. Set the shaft to the stigma and place it on the end of the shaft with a hole for the shaft and a hole for the drift pin to fix the shaft. To fix the column head and beam end, tighten a bolt with a washer set to the female threaded portion of the shaft from the hole for the shaft of the beam, tighten the column and beam, and set the shaft to the column base of the column A drift hole for fixing the shaft and a drift pin hole is provided, and the shaft portion of the shaft with the base plate is inserted into the shaft hole and set to drift. A wooden gate type ramen frame in which a drift pin is driven into the hole for the top pin, the shaft with the base plate is fixed to the column base, and the base plate portion is fixed to the anchor bolt of the foundation with a washer and a nut, and the column base is fastened to the foundation.

Fig. 4 shows the base plate of the shaft with the base plate that fixes the shaft provided with the groove for fixing the drift pin and the female screw for the bolt to the base plate with the bolt.

FIG. 5 shows a shaft with a base plate according to claim 2, wherein a shaft provided with a groove capable of fixing a drift pin is fixed to the base plate by welding.

The wooden gate type ramen frame of the present invention can be used for a wooden frame as a wooden gate type ramen frame for a small cross-sectional structure in both directions by combining it with an L type or a T type, and a long span opening without a wall or a large space building can be constructed.

The wooden gate-type ramen frame of the present invention can be used as an entire frame structure for wooden houses, etc., and can be used as many times as necessary in places where a wooden frame-type frame frame is required for a part of the wooden frame construction method in a garage at a narrow entrance. Since it can be constructed in combination with the wooden frame construction method, a cheaper mixed structure can be achieved compared to a mixed structure with steel structure or RC structure.

The wooden gate-type ramen of the present invention can be used for rehabilitation of wooden houses, etc., so that a large space can be taken because the pillar with the bearing wall and the bearing wall can be removed.
