Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-rise wall-type building structure having a framework of steel columns and steel frames pin-connected to the columns.

The wall structure made of precast concrete plates is mechanically unsuitable for high-rise buildings.

Therefore, in high-rise buildings, a rigid frame frame is constructed using steel columns and beams, and precast wall panels are erected on this framework.

In addition, various structures have been proposed in which steel columns are combined with beams or horizontal force transmitting materials embedded in precast wall plates, with places provided if necessary.

However, the conventional high-rise buildings have vertical and horizontal steel frames, which are heavy, and have a rigid frame structure, which makes it difficult to connect parts. Furthermore, column-shaped and beam-shaped structures appear inside the rooms, so there is room for improvement. There is.

This invention was developed in view of the above circumstances, and will be explained below with reference to the illustrated embodiments.

Steel column 1 made of H-shaped steel or lightweight H-shaped steel on the foundation
are established with the required spacing in the direction of several digits and beams according to the floor plan.

These steel columns 1 and 1 are regularly pin-jointed in both the girder and beam directions. With this, each joint of the X-shaped steel frame place 2 with joints protruding from the four corners of the wall is attached.

For example, in the girder direction, as shown in Figure 2, there are
In other words, they are arranged alternately in the vertical direction, and 1 in the horizontal direction.
Place steel frame places 2 between the columns.

As another example, as shown in FIG. 3, the steel frame places 2 are placed every other floor on the top and bottom, and are placed between two columns in the horizontal direction, and are spaced between two columns.

Further, in the beam direction, steel frame places 2 are arranged on each floor and each layer, but depending on the case, steel frame places 2 can be arranged on each floor between columns on both sides and every other floor between columns in the middle.

This X-shaped steel frame place 2 was designed to withstand both compression and tension, and was buried in a precast concrete wall plate 4 with reinforcing bars 3 arranged in a lattice pattern, with only the joints to the steel column 1 protruding. can be taken as a thing.

The outer wall plate 5 to be erected between the steel columns 1, 1 in the girder direction is provided with a necessary opening 6, and is attached to the steel columns 1, 1 using joining metal fittings or the like.

The outer wall board 5 is not limited to a precast concrete board, but may be one that constitutes a curtain wall.

The floor plate 7 is made of a precast reinforced concrete plate or cast-in-place concrete, and the floor plate 7 is pin-bonded to the wall plates 4 and 5 using joining metal fittings, etc., and is supported at two points at both ends.

The wall in which the wall boards 5, floor boards 7 and place 2 are buried can also be constructed of cast-in-place concrete.

As each member is assembled in the manner described above, column reinforcing bars are arranged around the steel column 1 as necessary, and concrete is poured.

At the same time, the steel frame place 2 or its joints, and the joint fittings for the wall plates 5 and floor plates 7 are buried in the concrete.

Figures 6 and 7 are plan views of odd and even floors in the case of the framework shown in Figure 2, and Figures 8 and 9 are plan views of even and odd floors in the case of the framework shown in Figure 3. This figure shows the arrangement of the main wall A, and the steel columns 1 and 1 are attached to the main wall A.
, an X-shaped steel frame place 2 is buried.

This invention has the above-mentioned configuration, and X-shaped steel places are arranged regularly between the steel columns in both the girder direction and the beam direction, with each joint directly connected to the steel columns with pins, and the horizontal force is processed. 1 or without providing horizontal force transmitting material, the floor load is transmitted from the wall to the column, and by burying the steel frame in concrete, the vertical load and column axial force during an earthquake are borne by the steel frame of the column and concrete.

Since the shear force during an earthquake is replaced by column axial force, no bending moment is generated in the column.

Therefore, even a building with about 10 stories can be designed using lightweight H-beam steel, and since there is no steel frame corresponding to the beam steel frame size, the weight of the steel frame of the entire building is reduced.

In addition, there are no column or beam shapes in the room, so the amount of walls can be reduced.

Furthermore, the joint between the steel column and the X-shaped steel frame place can be easily connected at the site by using a bottle joint, and the assembly is also easy.
