2. Description of the Related Art As is well known, a feeler-end frame is a structural frame in which a diagonal member is omitted from a truss frame, and is often used as a structure such as a bridge girder. Such a fieldend frame can be used as a main frame of a building, but in this case, it is usual that the fieldend frame is a steel framed steel frame composed of steel columns and steel beams.

By the way, when trying to adopt the above-mentioned fieldend frame in a steel reinforced concrete (SRC) building which is higher in rigidity and superior in earthquake resistance than a steel frame, The Fireendel frame is naturally made of SRC. That is, the SRC-structured pillars and the SRC-structured beams constitute a fuel-endile frame.

However, the SRC-structured fieldendir frame has the following problems as compared with the ordinary pure steel framed fieldend frame. That is, SR
Since it is inevitable that vertical cracks will occur in the concrete of the SRC columns and beams that compose the C-type fieldendile frame, the rigidity of the concrete may be reduced. The occurrence of distortion due to creep cannot be ignored, and therefore, there is a problem that the vertical deflection of the whole building is larger than that of the case of a pure steel structure. Such an increase in the vertical deflection causes, for example, distortion of the sash provided in the opening and a decrease in durability, and also leads to a decrease in the usability and appearance of the building, and measures for that are indispensable.

In a conventional general SRC building, concrete is cast on columns, beams, and slabs all at once after the steel frame is built. However, if this is directly applied to the construction of a fireendel frame, the above-described problem occurs. Therefore, in the present invention,
After the construction of the steel frame, the vertical load is processed by the column steel beam and the beam steel beam only by placing the slab concrete in advance, and then the concrete is cast on the column steel beam and the beam steel frame and SRC Complete columns and beams. Although the columns and beams constructed in this way are SRC structures, structurally, the beams and columns themselves bear the vertical load substantially in the same manner as steel structures. In other words, it functions as a finishing material and hardly receives any vertical load. For this reason, it is possible to sufficiently suppress the occurrence of cracks in the concrete of the SRC columns and beams, reduction in rigidity due to the cracks, and distortion due to creep.

FIG. 1 shows an example of a building constructed by the construction method of the present invention. In this building, an outer frame 3 is constructed by providing an earthquake-resistant element 2 (for example, a reinforced concrete earthquake-resistant wall or a brace, etc.) on an outer pillar 1, and an SRC-made fielder frame 4 is provided inside the outer frame 3.
In this embodiment, a pillar-free space is provided on the first floor.
Reference numeral 5 denotes an SR in which a column steel frame is covered with reinforced concrete.
Reference numeral 6 denotes an SRC beam (large beam) in which a beam steel frame is covered with reinforced concrete, and the column 5 and the beam 6 constitute a feederend frame 4. It is also possible to omit the above-mentioned seismic element 2 and to constitute the outer frame 3 only by the outer pillar 1.

In the construction of this building, concrete is cast after constructing the column and beam steel as usual, but concrete is cast on the column, beam and slab as usual. Instead, only concrete placing on the slab is performed in advance, and then concrete placing on the column and beam steel frames is performed to complete the SRC columns 5 and beams 6.

[0010] According to the above construction procedure, when the slab concrete is cast, the vertical load is supported only by the column steel beams and the beam steel frames, and the concrete cast thereafter functions as a finishing material so as to be vertical. Almost no load is applied. Therefore, although the column 5 and the beam 6 constructed in this way are structurally substantially SRC, the beam steel frame itself and the column steel frame bear the vertical load substantially similarly to the steel frame structure. Cracking, reduction in rigidity due to the cracking, and generation of distortion due to creep can be sufficiently suppressed. That is, according to the above-mentioned construction method, it is possible to effectively avoid the reduction of rigidity of columns and beams and the generation of large distortion due to creep, which are inevitable in the conventional general SRC-structured feederin frame. Therefore, it is possible to adopt a fieldend frame without any trouble.

In addition, in combination with the above-mentioned construction method, the beam is preliminarily cut into the steel frame and pre-loaded at the time of constructing the steel frame to control the deflection, and the concrete of the column 5 and the beam 6 is hardly cracked. If a technique such as adoption of special concrete is used in combination, cracking and creep of the concrete to be subsequently cast can be more reliably prevented.

As a similar construction method, it is conceivable to use a precast concrete plate (PC plate) instead of casting concrete on columns 5, beams 6, and slabs. It is beyond the scope of the structure, and not only is the fitting of fasteners for mounting the PC version complicated, but also the rigidity and seismic resistance are lower than the SRC structure, and the cost is higher,
Not preferred.

According to the present invention, after the column and beam steels constituting the SRC steel frame are constructed, slab concrete is cast and the vertical load is supported by the beam and column steels. After that, we adopted a procedure of casting concrete on column steel beams and beam steel frames to complete steel reinforced concrete columns and beams,
When the slab concrete is cast, the vertical load is supported by the column steel and beam steel, and the concrete poured thereafter has almost no vertical load, and therefore the concrete on the column or beam is cracked or Therefore, it is possible to sufficiently suppress the decrease in rigidity and the occurrence of distortion due to creep, and as a result, it becomes possible to employ the fieldendir frame as the main frame of the SRC building without any trouble.
