Abstract

PROBLEM TO BE SOLVED: To enhance vertical strength and horizontal strength on a wall surface by fixing a plurality of steel-made posts between an upper member and a lower member in the horizontal direction and fitting a wooden wall surface panel between the steel post-made posts. SOLUTION: A plurality of steel-made posts 3 are fixed between a steel-made girder 1 as an upper member in the horizontal direction and a foundation 2 as a lower member. Then, a face member 6 whose in-face resistance is large, such as a plywood is bonded with a wooden frame 5, thereby integrating and forming a wall surface panel, which is fitted between the steel posts 3, thereby constituting the wall surface. In this case, when the steel girder 1 is joined with the steel posts 3, and when the foundation 2 is joined with the steel posts 3, they must be joined with a bolts which is highly storing and reliable as well. The lower member may be used as the steel girder or the foundation panel. As described above, the steel-made posts 3 are adapted to shape the vertical force and distribute their specific functions for every material, thereby troubleshooting the structural problems which may arise from multi-services and enabling excellent strength effects to be exerted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall surface structure including a wall surface panel used together with a steel frame assembly used in a house or the like.

[0002]

2. Description of the Related Art Conventionally, a wall structure using wooden wall panels has been widely used in houses and the like, but it is generally used in a wooden building. In the case where a wooden wall panel is used in a steel structure, it is generally used as a wall panel that does not bear proof stress, and there are few cases where proof stress is borne.

Generally, a wooden wall panel is directly joined to a girder, foundation or base by nails or bolts. Therefore, the horizontal force is directly transmitted to the wall panel via the nails and bolts joining the wall panels. In addition, the lifting force generated on the force-applied side of the wall panel is generally dealt with by nailing a metal band tightly bound to the foundation to the wall panel.

In addition to this, a method of directly fixing the wall panel to the foundation with anchor bolts, and in order to cope with a larger lifting force, a metal member called a hole-down hardware is fixed to the wall panel vertical frame with a bolt, and the metal product is fixed. Methods such as fixing to the foundation with anchor bolts are being considered.

[0005]

However, in the above-mentioned conventional example, the joint portion between the wall panel and the girder or the foundation of the other member is designed by increasing the number of nails and bolts in accordance with the external force. Since it is strongly constrained locally by the metal that suppresses lifting, stress concentrates near the joint. Therefore, the proof stress of the wall panel is determined by the local breakage near the joint, and the horizontal proof strength of the wall panel, which is increased by bending and bonding, cannot be fully utilized. Further, since the proof stress of the joint is generally determined by the shear proof stress of the wood, the proof stress varies greatly depending on the wood used.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a wall structure using a wall panel that is used together with a steel frame framework having excellent vertical and horizontal proof strength.

[0007]

In order to achieve the above object, the wall structure by the wall panel used together with the steel frame assembly according to the present invention has a plurality of steel columns between the upper member and the lower member in the horizontal direction. Is fixed, and wooden wall panels are fitted between these steel columns to form a wall.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 shows a perspective view of an embodiment of the present invention, in which a plurality of steel columns 3 are provided between an upper steel girder 1 and a lower foundation 2, and a wall panel is provided between these steel columns 3. Four
Are fitted. The wall panel 4 is made of wood, and a wooden frame 5 is integrated with a face material 6 having a large in-plane shear resistance, such as plywood, by bonding. And steel girder 1 and steel pillar 3,
The foundation 2 and the steel column 3 are joined by bolt joining which has high strength and high reliability.

FIG. 2 shows a stopper 7 for the steel girder 1 and the foundation 2 of the wall panel 4, and this stopper 7 is installed inside the wall panel 4 in advance. The stopper 7 is composed of a deformed portion 8 formed by bending a metal plate and a rod portion 9 with an internal screw inserted through the deformed portion 8. The rod portion 9 penetrates a hole provided in the wooden frame 5. And is protruded to the outside, and a bolt 10 is screwed into this protruding portion via a foundation 2 as shown in FIG. As described above, the wall panel 4 is fixed to the steel girder 1 and the foundation 2 by screws through the metal pieces 7 provided at at least four corners of the wall panel 4, and the rod portion 9 of the metal piece 7 is attached to the wall surface. It is also used to fix the hanging jig when the panel 4 is hoisted.

The present embodiment has the above-mentioned structure, and since the steel columns 3 are arranged on both sides of the wall panel 4, in addition to bearing the vertical force such as floor load, the wall panel is acted upon when the horizontal force is applied. Bear the reaction force of the lifting force of 4. The wall panel 4 bears only horizontal force such as seismic force, and does not bear vertical force. Since the steel girder 1 and the foundation 2 are arranged on the upper and lower portions of the wall panel 4, these not only transmit the vertical load from the floor to the steel column 3, but also integrally with the steel column 3,
It works to suppress the lifting force of the wall panel 4.

In the horizontal force transmission mechanism, the horizontal force input from the second floor and the outer wall is first transmitted to the steel girder 1, and then from the steel girder 1 to the steel column 3 by the fastening rod portion. As a result, the steel columns 3 push the wall surface panel 4, and the horizontal force is transmitted to the wall surface panel 4 by this bearing pressure. The horizontal force transmitted to the lowermost portion of the wall panel 4 pushes the steel column 3 on the side opposite to the applied force, and the horizontal force is transmitted from the steel column 3 to the foundation 2 via the joining rod portion with the foundation 2. It At this time, the wall surface panel 4 is lifted up on the applied side, but it is suppressed by the steel girder 1 and the foundation 2 that are tightly connected by the steel column 3, and early destruction due to local concentration of stress is prevented. Since stress is transmitted to the steel girder 1 and the foundation 2 by the bearing pressure, the form of failure is due to the embedding of the frame material of the wall panel 4, so brittle failure does not occur. Thus, the proof stress of the wooden wall surface panel 4 against the horizontal force is improved by restraining the wall surface panel 4 with the steel frame column 3, the steel girder 1, and the foundation 2, and a stable value can be obtained.

Further, an out-of-plane force such as wind pressure is applied to the wall surface panel 4, but is transmitted to the steel girder 1 and the foundation 2 by the metal member 7 fixing the wall surface panel 4. However, when the horizontal force acts, if the metal 7 is too tightly constrained, local damage occurs around the metal 7 and the yield strength is reduced, so a special shape is adopted. That is, the rising portion of the deformed portion 8 of the metal 7 is bent early as shown by the dotted line in FIG. 3 in response to an external force, so that the rod portion 9 is pushed outward and no larger stress is applied. ing. Further, the metal 7 does not break in the load region where the design load level is low, and contributes to the improvement of the initial rigidity.

On the second and third floors, the steel columns 3 are mounted between the upper and lower steel girders 1.

[0014]

As described above, the wall structure using the wall panel used in combination with the steel frame structure according to the present invention is a mixed structure system of a steel structure and a wooden structure, but the vertical force in the load processing method is steel. By clearly dividing the functions for each material, such as the pillars bearing the horizontal force and the wooden wall panels bearing the horizontal force, structural problems arising from mixed use can be solved, and the strength is excellent.
