Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building frame structure.

The structural type of the main structure of a building in terms of structural strength is generally a rigid frame of columns and beams with concrete walls installed at appropriate intervals both vertically and horizontally.

Although there are problems with this type of structure, such as the following, no methods have emerged to solve them, so the reality is that most buildings adopt this structural form. be.

First, there are problems with workability, especially formwork work. The densely packed pillars, uneven large beams and small beams, and the workability of assembling formwork and pouring concrete for walls is extremely poor. It cannot be ignored that this poor workability leads to high costs and affects the quality of the finished product.

Next, in terms of structural strength, there is a problem with concrete walls. Not only as a partition, but also as a vertical,
Appropriate placement of horizontal load-bearing walls is essential for horizontal load-bearing walls, but mechanical analysis results for concrete walls vary, and it is said that there is no wall without any cracks. The current situation is that the cracks have become an eternal issue.

In terms of problems in the use of buildings, the beam-shaped protrusions hinder the usable space and design, and concrete walls have the disadvantage that they are difficult to accommodate changes to the floor plan.

It is an object of the present invention to provide a novel structure that solves each of the above-mentioned problems.

An embodiment of the present invention will be described below based on the drawings.

The frame structure according to the present invention can be roughly divided into a rigid frame brace frame structure A and a flat slab structure B.

When viewed from above, the frame structure A with rigid frame braces has a width of 3.
For each span, in the column direction, they are arranged at seven spans on the left and right, and at appropriate intervals in the center. In other words, this frame structure A consists of SRC columns 1 and beams 2.
It has a structure in which a factory-processed steel brace 3 is attached to the rigid frame frame except for the part that will become the opening K.

As shown in FIG. 2, this brace 3 is arranged in an X-shape with two spans and two layers, and functions as a horizontal proof load.

As shown in Figures 1 and 3, the portion 4 surrounded by the rigid frame brace frame is the independent column 1.
1 and the haunch of the capital of the column, and the capital plate 13 is the slab 1
The flat slab structure B has a configuration that evenly supports the load on 4.

In this example of the floor plan, as shown in FIG. 1, only the cross section in the center adopts a general structure with large beams G and small beams G, instead of a flat slab structure.

This is because this building is an example of a warehouse design, and the central cross section has a large span and must be constructed to withstand the special load of being used as a roadway for trailers and the like. Of course, the invention is not limited to warehouses.

Regarding the foundation, as shown in Figure 3, SRC columns 1 or RC columns 11 are erected directly on top of the expanded bottom piles P cast in the field.

In FIG. 1, 5 and 5a are elevators, 6
is a duct space, and 7 is a staircase.

In this way, the present invention has a structure in which rigid frame frames with braces are appropriately arranged in accordance with the design load in a flat slab structure without beams. It has a frame structure that can withstand loads.

Therefore, the present invention has the following effects.

First, by omitting concrete load-bearing walls, formwork work is no longer required, further improving the workability of the frame work and making it more economical. Formwork supports such as columns and slabs can be easily repurposed and moved, making it easier to move materials and people. It is more advantageous than the conventional example in terms of structural strength and quality. In other words, in the case of a steel frame (steel material), the chemical composition and mechanical properties of which have been elucidated, mechanical analysis is easy, whereas concrete walls have different evaluations based on mechanical reaction analysis results. This ultimately leads to improved quality and accuracy.

Walls with cracks also pose concerns about fumigation, such as in warehouses. Furthermore, the openings can be used effectively to improve the usability of the building. Since the living room is a flat slab, the ceiling height is higher than that with beams, which is particularly advantageous in warehouses.
