Description

Shaft member connection structure and connection method

The present invention relates to a shaft member connection structure and a connection method, and in particular, by bonding a finishing plate of a certain shape to the upper flange and lower flange of both ends of the H-beam used as braces for temporary retaining construction, and closing between the upper flange and the lower flange.

BACKGROUND ART Conventionally, in buildings and other structures, buckling restraint members are used as structural elements to resist horizontal forces such as seismic force or wind force.

This buckling constraining member is interwoven between the layers of the main frame of the structure, and when a large interlayer deformation occurs, the steel material serving as the core material absorbs energy as a plastic deformation to attenuate vibration.

As for the buckling restraint member, it is necessary to install a steel central axial force member in the closed section of a steel pipe, etc., and fill the periphery of the central axial force member with a room temperature hardening material such as concrete, and in this type, it is necessary to prevent adhesion to concrete. , by installing an anti-adhesion film around the central axial force member, the concrete and anti-adhesion film are applied over almost the entire length of the steel pipe.

The above-described buckling restraint member has the following problems.

(1) The amount of use of a room temperature hardening type material such as concrete is large, and on the other hand, as the manufacturing process increases, the process control becomes complicated, and the cost is high and its own weight is large.

(2) The bending of the central axial force member is easy to occur when pouring concrete, and the quality control work of materials such as concrete increases, and at the same time, drying time is required.

(3) When the central axial force member is made of a steel plate, local buckling tends to occur at the end joint portion, so measures such as enlargement of the plank or reinforcement by welding a steel plate to the joint portion are necessary.

(4) It is necessary to exclude concrete by installing a flexible material at the end of the expansion and contraction part so that the expansion and contraction of the central axial force member is free.

(5) When installing a bolt joint at the end, the width of the joint is often widened to compensate for the cross-sectional defect caused by the bolt hole.

Therefore, it is necessary to increase the inner diameter of the closed cross-section of the steel pipe so that the joint can be accommodated in manufacturing.

(6) The Young's modulus of concrete is about 1/10 of that of steel, and since buckling strength is generally proportional to Young's modulus, the buckling restraint effect of concrete is about 1/10 of that of steel. There is a problem that it is nothing more than a simple filling material between the steel pipes of

Therefore, the efficiency of the buckling restraint decreases and is also a factor in increasing the cross-sectional shape of the members.

Accordingly, in order to solve the above problems, Patent Registration No. 10-2055005 shaft member connection structure and connection method has been proposed.

As shown in FIGS. 1 and 2, the shaft member connection structure includes a steel pipe 10 having a predetermined diameter and length; At one end of the steel pipe 10, an axial force end plate 20 made of a steel plate having a predetermined thickness and diameter is welded to one end of the steel pipe 10, and an inner tube 30 made of a tube or iron tube for a shaft member having a constant diameter and thickness. class; It is inserted and welded to the outer circumferential surface of the inner tube 30 and is composed of an exterior 40 made of a steel tube or iron tube for a shaft member having a constant diameter and thickness, and is cut at a predetermined angle to the periphery of the axial force end plate 20 The part 22 is formed, so that the axial force end plate 20 can transmit the axial load applied to the inner tube 30 at a right angle without loss, and the outer tube 40 prevents buckling occurring in the inner tube 30 . It is characterized in that it is configured to do so.

In addition, the above-described shaft member connection method is cut to have a predetermined angle on the outer periphery of the axial force end plate 20 having a constant diameter and thickness to form a cut-out portion 22, and the cut-out portion 22 is formed axial force finish After manufacturing the inner tube 30 by welding the plate 20 to the end of the steel tube 10 having a predetermined diameter and length, and inserting the outer tube 40 over one side and the other side of the inner tube 30, After inserting the outer tube 40 with the axial force end plates 20 attached to the inner tube 30 facing each other or spaced apart from each other at regular intervals, the inner tube 30 and the outer tube 40 are welded together It is characterized in that it is formed with

The conventional shaft member connection structure and connection method configured as described above is composed of an exterior and an axial force end plate and an inner tube accommodated therein. Since the yielding of the inner tube occurs in a single or multiple axial force end plate in the middle part, by adjusting the cross-sectional area of the axial force end plate, an arbitrary yield axial force that is difficult to buckle in the axial force end plate can be obtained.

In addition, by processing the outer periphery of the blocking plate, the cross-sectional shape can be sufficiently secured in the inner tube.

And, since the junction part can be inserted into the exterior, the axial force end plate and the inner tube can be accommodated in the exterior after the production of the junction part between the axial force end plate and the inner tube is finished.

In addition, by installing an axial force end plate at the end of the inner tube to prevent sagging and buckling due to the self-weight of the inner tube and installing the outer exterior, the axial force end plate can transmit the axial force applied to the inner tube at a right angle without loss, and the appearance has the effect of preventing buckling occurring in the inner tube.

However, the conventional shaft member connection structure and connection method configured as described above uses a circular steel pipe as a main member as a brace as shown in FIGS. 1 and 2, so it is difficult for an operator to pass the steel pipe brace during work. It is inconvenient, and there is a disadvantage that a separate movement path must be newly installed or additionally installed, and in particular, there was a problem in that it was difficult to connect and combine the braces made of round steel pipe, wales, and inclined braces.
