[Problem that the idea aims to solve]

In the conventional column configuration described above, the pillars are essentially buried in the foundation concrete23. Since it is supported by the anchor bolts 24..., the vertical direction of the column main body 20 is An extremely stable upright position is maintained in both directions. Also, regarding the head of each column main body 20... However, by fixing each beam member 25, a relatively stable mechanical configuration is maintained.

0004 However, due to loosening of the ground or earthquakes that cause the foundation concrete to move horizontally, If foundation fluctuations occur due to This can easily cause the entire building to lean. Also like this In order to deal with the phenomenon, it is possible to strengthen 23 parts of the foundation concrete, but For this purpose, large-scale foundation work will be required, and the above-mentioned drawbacks will be completely eliminated. Can not do it.

[0005] Therefore, in order to eliminate the above-mentioned drawbacks, the present invention has a simple structure that can be used for building pillars. The object of the present invention is to provide a configuration that can reliably strengthen the fixed state of the legs in the section.

[0006]

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the present invention has the following structure for locking the legs of building columns: I did it like this. That is, locking portions having extreme ends protruding in both directions are provided on surfaces near both ends, respectively. The locking rod constitutes the leg of the column, and the column main body is placed on the surface located in the locking direction. The insertion hole located closer to the edge and the narrower engagement hole located closer to the edge are connected in series. A cutout is formed in the hole, and a hole is formed along the corresponding edge across the very end of this engagement hole. and a base plate having a locking member on its surface, both locking portions of the locking rod. into the respective corresponding insertion holes and the end portions of the locking rods into the engagement holes. At the same time as engaging, place the locking part on the surface where the engaging hole of the corresponding base plate is located. It is characterized in that it is achieved by locking.

[0007] In the configuration features of the present invention described above, the locking rod can withstand applied tension and compression. It is made of strong material, such as steel, into a rod shape. Also, the length of this locking rod is compatible. It is formed with a length that corresponds to the installation interval of the pillars, and the length corresponds to the installation position of each pillar. , placed under tension in three or two directions.

[0008] Furthermore, the engagement hole on the base plate surface can receive the end portion of the locking rod. At the same time, the locking rod has a width shorter than the length of the locking portion of the locking rod. In addition, the present invention further improves the locking structure between the locking portion and the base plate described above. A plate-shaped stopper member is fitted into the insertion hole on the base plate surface. The present invention includes a leg locking structure of a building column, characterized in that the leg locking structure is made of a building pillar.

[0009] Note that the stopper member described above is fitted into the insertion hole on the base plate. For example, as long as the plate-like part has a plate-like part to be It is possible to have various configurations such as one fixedly fixed in a protruding manner on the surface of the seat member.

0010 In addition, the above-mentioned fitting configuration of the stopper member is on the same base plate surface. This is necessary for locked locking rods that do not have locking rods in symmetrical positions. That is, For pillars located at the corners of buildings, all locking rods are located at the center of the sides. This is essential for some locking rods.

[0011]

[Effect]

In the configuration according to the present invention, a mechanism for engaging and locking the locking rod and the base plate is provided. The work shall be carried out prior to or at the same time as the installation of the base plate on the foundation concrete surface. done in time. In addition, both ends of the locking rod are engaged and locked on two corresponding base plates. At the same time, the locking parts at both ends are placed on the corresponding locking member surface on the base plate. The base plates are in a state of being pressed against each other, and these base plates are locked together in a state of tension. Ru. Therefore, each column erected on the foundation concrete surface via the base plate When a horizontal force is applied to the lower part of the main body, each locking rod is act as tensile or compressive stress from the base plate. In this case, the above Any column body attempts to swing so as to compress one locking rod due to the acting force. When the locking rod is in a symmetrical position, a tensile stress is generated on the locking rod, which causes this swinging motion. acts to prevent As a result, the standing condition of each pillar body of the building will be stabilized.

0012 In addition, the stopper member described above is placed in a predetermined position after the locking operation of the locking rod described above. Can be fitted. This stopper member is fitted in the corner of the building or This is particularly effective for a pillar structure located at the center of the side surface. That is, the base play If the locking rod is not located at a symmetrical position corresponding to the locked locking rod on the surface of the base, A stopper member is fitted into the insertion hole at the position where the locking rod is locked. Therefore, in the case described above, the locking rod may move and the locking state may be released. You can prevent it from spinning. This anti-separation effect is achieved by the base of each column. In addition to the above-mentioned tension and compression effects on each locking rod on the plate, This contributes to stabilizing the standing state of each pillar main body.

This engagement hole 5 is located in the pillar part. An insertion hole 6 is provided at a position closer to the main body 3, and an end edge portion is provided with a narrower width in series with the insertion hole 6. The engagement hole portion 7 is formed in a notch shape at the same position. Also, this engagement hole 7 part The base plate 4 straddles the extreme end of the engagement hole 7 and extends along the corresponding edge. It is defined by a locking member 8 fixed on the surface. In addition, 9 is the base plate These are bolt holes drilled near the corners of 4.

[0015] Further, as shown in FIG. 4, the locking rod 1 is made of a long material with a rectangular cross section. Locking parts 2, 2 having extreme ends protruding in both directions are fixed on the surfaces near both ends, respectively. and have it. The width of this locking rod 1 and the size of its locking portion 2 are as explained below. It is set so that a locking configuration can be realized.

First, insert the locking part 2 into the insertion hole 6 from the back side of the base plate 4 and attach the locking rod. Extend one end into the engagement hole 7 and place the locking part 2 against the base plate 4 surface. and extend it to the upper position.

[0017] Next, move this locking rod 1 along the base plate 4 surface and lock it with the locking part 2. It extends to the position where it comes into contact with the member 8. After operating in this way, Figure 6 and Figure 7, this base plate 4 has bolt holes inserted into bolt holes 9, respectively. It is fixed on the predetermined foundation concrete 10 surface via car bolts 11. Furthermore, 12 is the fixing nut for this fixation.

[0018] At this time, both ends of the locking part 2 are connected to the base plate 4 surface where the engagement hole part 7 is located. The locking rods 1 are placed on the top to maintain the locking state of the locking rods 1, and each locking rod 1... is connected to the corresponding base. A tension is created between the splay plates 4, 4, and their locking is stabilized.

[0019] Figures 8 and 9 also show the base plate in the column configuration located at the corner of the building. The locking configuration of the locking rod 1 with respect to the seat 4' is shown. This base plate 4' is mutually It has locking directions only in two directions perpendicular to the . Therefore, depending on the locking direction, It has two engagement holes 5, 5. The locking structure for these locking holes 5 is the locking rod described above. This is the same as the locking configuration of No. 1. In addition, in this case, the plate is further inserted into the insertion hole 6. This includes a configuration in which a stopper member 13 of a shape is fitted. Fitting configuration of this stopper member 13 prevents the end of the locking rod 1 from moving within the engagement hole 5.
