Description

[Detailed description of the invention] This invention relates to buildings.

In a conventional steel frame structure building, a pair of braces are strung across each rectangular frame structure consisting of a pair of adjacent columns and a pair of adjacent beams along their diagonal lines. This gives it strength. However, there was a problem in that the braces became a hindrance, making it impossible to form openings such as windows and entrances within the rectangular frame structure. On the other hand, if each rectangular frame is reinforced with braces instead of the above-mentioned braces, openings such as windows and entrances can be formed within the rectangular frame, but since the braces support the base ends of the columns, When a horizontal load is applied to the upper end of a column from the outdoor side, a large concentrated stress in the opposite direction to the horizontal load is generated at the base end of the column via the brace, and as a result, depending on the brace, sufficient Another problem arises in that the load-bearing strength is no longer obtained and the strength of the entire building is significantly reduced, making it dangerous.

Therefore, an object of the present invention is to provide a building in which openings such as entrances and windows can be formed within a rectangular frame structure, and which provides sufficient strength as a whole.

An embodiment of the present invention will be described with reference to FIGS. 1 to 9. In other words, as shown in Fig. 1, this building has a girder side rectangular frame structure A consisting of a pair of columns 1 and 2, a second floor beam 3, and an underground beam 4 (foundation) on the girder side. The corners are reinforced with beams 5 (rigid frame structure), and as shown in Figure 2, a pair of columns 1 and 6 and a second floor beam 7 are installed on the gable side that is directly exposed to the girder side.
The gable side rectangular frame structure B, which is composed of an underground beam 4 and an underground beam 4, is reinforced with braces 8 (brace structure). In this case, the column 1 is used in common for both rectangular frame structures A and B, and the girder side rectangular frame structure A and the girder side rectangular frame structure B form the frame of the projecting corner of the building.

To explain in detail the connection structure of each part, the column 1 is constructed of I-beam steel as shown in Fig. 3, and an end plate 9 is welded to the lower end surface of the column, and it is planted at the top of the underground beam 4. The pillar 1 is erected and fixed to the underground beam 4 by passing the anchor bolt 10 through the end plate 9 via the spacer 11 and fastening the nut 12.

As shown in FIGS. 3 to 5, the cane 5 is

6 are arranged at predetermined intervals above and below the column 1, as shown in FIG.
It is connected to the column 1 with a bolt 27 and a nut 28 (FIG. 8). Furthermore, one end of the second floor beam 3 is inserted between the horizontal pieces 26b of both connecting fittings 26 via a spacer 29, and the connecting fittings 26 are tightened with bolts 30 and nuts 31 through bolt insertion holes 26d (Fig. 7).
Fix it to.

The connection between the pillar 2 and the second-story beam 3 shown in FIG. A girder-side rectangular frame structure A is constructed, and the lower corner portions of both ends of the girder-side rectangular frame structure A are reinforced with braces 5, respectively.

On the other hand, as shown in Figure 2, on the wife's side,
By welding gusset plates 32 and 33 to the upper and lower positions of the outdoor surfaces of both columns 1 and 6, respectively, and extending both ends of the second floor beam 7 between the two gusset plates 32 and 33 and fixing them with bolts 34, Above 2
The floor beam 7, the underground beam 4, and both columns 1 and 6 constitute a gable side rectangular frame structure B. FIG. 9 is a front view of the brace 8. This brace 8 consists of a pair of steel rods 35, 3
Bolt insertion holes 36, 3 are provided at one end of each of 5'.
The connecting plates 37, 37' with 6' are welded, and male threads 38, 38' are carved in the other ends of the steel bars 35, 35' so that they are opposite threads to each other.
Connect the male screw 3 to the female screw provided at both ends of the fastener 39.
8 and 38' are screwed together, and the gusset plate 3 is attached along the diagonal line of the rectangular frame structure B on the end side.
Stretch it so that it crosses between 2 and 33. That is, the connecting plates 37, 37' are placed along the gusset plates 32, 33, respectively, and both plates 3
Both ends of the brace 8 are attached to the gusset plates 32, 37' by passing bolts (not shown) through the bolt insertion holes 36, 36' provided in the holes 36, 37' and tightening nuts.
33, the brace 8 is tensioned between the two gusset plates 32, 33 by tightening the steel bars 35, 35' by screwing the fastener 39 in the manner of a turnbuckle.

In this way, since the girder side rectangular frame structure A is reinforced with the braces 5, it becomes possible to form an opening such as an entrance or a window in the girder side rectangular frame structure A. Further, during construction work, there is an advantage that workers can enter and exit and materials can be taken in and out through the girder side rectangular frame structure A. Moreover, the girder side rectangular frame structure A is
As a result of reinforcing the girder side rectangular frame structure A with the braces 8, the load-bearing strength is lower than that when the girder side rectangular frame structure A is reinforced with the braces 8. Because of the reinforcement, the strength of the projecting corners of the building as a whole of both rectangular frame structures A and B does not decrease so much, and sufficient load-bearing strength is obtained for the entire building. In addition, as a result of reinforcing both rectangular frame structures A and B with the braces 5 and braces 8, the cross-sectional shape of each member of the rectangular frame structures A and B is made smaller than in the case where they are not reinforced with the braces 5 and braces 8 at all. Furthermore, as the processing of the pillars 1, 2, and 6 becomes simple, transportation, warehouse management, and handling become easy. Moreover, since both rectangular frame structures A and B can be installed adjacent to each other, the girder side rectangular frame structure A can be formed with a doorway or window opening, and the girder side rectangular frame structure B can be used as a parting wall. It is suitable for apartment buildings where the entrance/exit faces one side.

In the above example, the girder side rectangular frame structure A was reinforced with the braces 5 and the girder side rectangular frame structure B was reinforced with the braces 8, but on the contrary, the girder side rectangular frame structure A was reinforced with the braces 8. Then, move the rectangular frame structure B on the gable side to the support 5.
It may be reinforced with.

As described above, in the building of the present invention, one of the adjacent sides of the pillar is supported by a brace, and the other side is applied with a brace, so that openings such as windows and entrances are formed within the rectangular frame structure. This is possible, and has the effect of providing sufficient strength for the building as a whole.
