Description

In the present invention, as shown in the example of FIG. 1, a house having a space of 10 meters or more between beams, which is composed of a flat surface, is connected by using a commercially available size pipe generally found in scaffolding as an aggregate to ensure the strength equivalent to that of a steel frame. Regarding the structure.

Traditionally, pipe houses have been reinforced by using simple connecting materials inside and outside the pipes to increase their strength, and by assembling pre-assembled pipes in the truss structure by welding diagonal materials. .. Regarding the above, the finished strength does not reach the steel frame strength against a certain load, and the following is robust, but requires a large number of engineers such as welding technology, surface treatment technology and on-site assembly. Is.

FIG. 2 is an external perspective view showing two forms, an integrated type and a split type, in which adjacent pipes are connected by a connecting component. The height position of the integrated rib corresponds to the thickness of the split type connecting material.

FIG. 3 shows a disassembled split type of FIG. 2, a curved pipe knob portion having a plurality of fastening holes matching the curved surface of the pipe, and a flat surface portion provided with a plurality of fastening holes for connecting to the plate-shaped connecting material. It is an exploded perspective view which shows the Tsukami metal fittings composed of, and the plate-shaped connecting material which matched the inner method of the side-by-side pipe.

According to claim 1, due to the bending load of the side-by-side pipe, the connecting material is rotated, which causes a shearing force to the pipe fastening material at the tensile side contact portion. Initially, it resists it with the bending force, but when the rotational force increases further, elastic deformation begins at the bending boundary of the joint with the pipe. Even in that case, since the fastening hole swings at a right angle or more in the direction opposite to the tensile force, the shearing force on the fastening material is reduced. Therefore, there is an effect that the number of fasteners can be reduced and an effect that the size of the fasteners can be reduced.

According to claim 2, in the side-by-side pipe, a part of the connecting material is slightly elastically deformed by a set load or more, and all the connecting materials arranged at a plurality of places share the shearing force generated between the side-by-side pipes. By realizing the characteristic of having both flexibility and rigidity as shown in FIG. 4, it is expected to have the effect of preventing premature fracture due to a concentrated load on the local area and increasing the overall fracture limit value.

Generally, braces are provided in the girder direction orthogonal to the beams, but by providing this structure instead, many passage-shaped openings shown in FIG. 7 can be installed, and in the case of a continuous building, a valley. It is also possible to form the maximum number of passages between the interiors in the girder direction of the section.

By arranging the roof at a plurality of places as shown in FIG. 7 instead of bracing, contact breakage due to local concentration does not occur.

In the foundation, it is necessary to fasten steel bolts to the solid cast-in-place concrete foundation, which is usually required, but in vertical and diagonal columns, the rotational force due to shearing is difficult to be transmitted to the foundation at the column base, which is simple. Since it is only necessary to support it, it is sufficient to bury a foundation block of ready-made products, or to take measures to prevent subsidence such as piles in soft ground. It leads to the maintenance of. At the same time, this not only reduces the assembly cost of professional engineers, but also makes it easy to disassemble, relocate, maintain, and reuse, so it can be expected to have considerable economic benefits for consumers.

Regarding the split type connection method as shown in Fig. 3, it is necessary to increase the degree of the angle of the slanted columns in order to improve the load-bearing strength, especially in heavy snowfall areas, so the increase in types is suppressed from the initial spread. In addition, it is expected that the cost increase due to the increase in size of the forming press will be suppressed, and the cost will be reduced by facilitating distribution by reducing the number of parts by standardizing the parts.

As shown in the girder row in Fig. 7, the column structure made of three aggregates by arranging the adjacent pipes in a straight line has about four times the deflection strength and about twice the cross-sectional performance in terms of strength. Has the effect of raising. This is an example that also saves vertical columns.
