は、柱を一旦切断して溶接するものであるため高
い溶接技術を要求されるもの等の欠点がある。Problems to be Solved by the Prior Art and the Invention When a beam, etc. is installed in the middle of a steel pipe column as described above, a large moment is generated at the joint, and there is a risk that the beam may bend under horizontal load. Therefore, it becomes necessary to reinforce this node part by some method. Conventionally, such reinforcing methods include one in which the entire structure is made of cast steel and a collar 1 is integrally formed on the outer periphery of the joint, as shown in Fig. 1A, and a steel pipe column as shown in Fig. 1B. 2 is cut and a reinforcing plate 3 is welded to the cut part,
Alternatively, as shown in Figure C, there is a structure in which a reinforcing plate 4 is fitted around the outer periphery of the steel pipe column 2 and fixed by welding. However, among these, the above figure 1A
Types C and C only reinforce the outer periphery, so they may not be strong enough for items that receive heavy loads. However, there are disadvantages such as requiring a high level of welding technology.

なされたものである。 Furthermore, as a means for reinforcing the strength of the steel pipe column, filling the steel pipe column with concrete is used. (For example, see Japanese Patent Application Laid-Open No. 11321/1983). However, in conventional steel pipe columns filled with concrete, parts other than the joints are filled with concrete, which results in wasted use of concrete, resulting in an overall high cost and weight. On the other hand, as a method of filling only the joints with concrete, a method in which air is sealed outside the joints has been considered (Japanese Utility Model Publication No. 35609/1983). However, in this case, in addition to bolts to connect the beams, a special member such as a bag containing air is required, which is expensive.
Moreover, there is a drawback that the bag may be damaged and the concrete may move or fall. Furthermore, when filling only the joints with concrete, it has conventionally been necessary to insert a hose from the end of the steel pipe column, which has the drawback of poor workability and high cost. The present invention was made with the aim of eliminating such conventional drawbacks in steel pipe columns that are filled only at the joints of concrete.

The invention is characterized in that concrete is injected through an injection hole formed in the part to cover the through bolt and fill only the inside of the joint part with concrete.

り落下するという虞れがない。 The present invention has the above-mentioned configuration, and according to the present invention, the joint portions through which the through bolts are penetrated are filled with concrete, so the strength is high, and therefore, local loads are not applied to these portions. There is no risk of deformation even if the bolts are hooked, and since the through bolts are supported by concrete, there is no need to secure them by welding or the like, so advanced techniques such as welding techniques are not required. In addition, in this invention, concrete is injected through the injection holes provided at the joints of the steel pipe columns, so it is easy to determine the injection position and the workability is good, and the through bolts are covered with the concrete. Therefore, once the concrete is fixed, the through bolts will reliably prevent the concrete from moving or falling.
Unlike the conventional method of inserting a bag filled with air,
Since the bolts used to connect the beams are used, there is no need for such special members and the construction can be made at low cost, and there is no risk that the bag will tear and the concrete will move or fall.
