Description

The present invention relates to an arrangement structure of a ceiling base frame.

Among the ceiling bases, a grid-shaped frame that is manufactured in advance at a factory can be called a ceiling base panel frame (or a ceiling panel frame). Ceiling base panel frames include wooden panel frames and steel (light iron) panel frames.

A conventional method of connecting a wooden panel frame to a pillar is, for example, in connecting the ends of the wooden panel frame from all sides to the stigma of the pillar, which is formed of square steel pipes. At the site, the end of the wooden panel frame is cut, and the stigma is fitted into the cut portion. Since such a cut portion is provided in the wooden panel frame, by taking measures to bridge the wooden panel frames perpendicular to each other with a reinforcing material, the cut portion of the wooden panel frame is reinforced with the reinforcing material. , the stigma of the pillar and a plurality of wooden panel frames are connected to each other while surrounding the stigma of the pillar with a plurality of reinforcing members. When forming this connection structure, there are problems that it takes time and effort to cut the wooden panel frame on site, and that a reinforcing material needs to be attached at the cut portion.

In addition, the wooden panel frame is relatively heavy, and the dimension of the wooden panel frame is half the width of the module dimension of the building (for example, the width of one module is 910 mm or 1000 mm, and the width of one module is represented by 1P). In a form in which wooden crosspieces are assembled in a grid pattern with a grid interval of 0.5P, a large size of about 1P in width and 2P to 4P in length is often applied. In this way, the weight of a large wooden panel frame has a great influence on the workability, making the construction itself difficult, and in addition, the above-mentioned on-site processing is required, so that the construction labor becomes conspicuous.

On the other hand, Patent Document 1 proposes a conventional method of connecting a steel panel frame to a column and a panelized metal ceiling structure formed by this connection method. This ceiling structure uses a plurality of light-iron ceiling panel frames in which joints are joined between a pair of parallel main frame members. It is formed by hanging from the building frame.

Then, as shown in FIGS. 11 and 12 of Patent Document 1, regarding the fit of the part where the ceiling spreads on both sides of the independent pillar, the ceiling panel frame is provided with two rows of panels that are adjacent to each other with the main frame members. Independent columns and spacers are interposed between the panel rows. The spacer, like the tethers at the ends of the ceiling panel frame, is made of light iron with an upward lip channel and has bridge hardware that rides over the tethers on both sides of the spacer. The bridge hardware has a downward groove shape, and both flanges thereof are provided with locking pieces protruding downward for engagement with the lips on both sides of the connecting members and the spacer. has trapezoidal side surfaces facing downward, and has locking notches on both sides of the proximal end with which the lip engages.

JP-A-9-111948

According to the panelized metal ceiling structure described in Patent Document 1, it is lighter than a wooden panel frame, so workability is improved. No need for cutting. However, when connecting columns and steel panel frames, it is necessary to interpose spacers between the panel rows and attach bridge metal fittings so as to straddle the connecting materials on both sides of the spacers, increasing the number of parts. do.

In addition, in the conventional connection structure between the ceiling base panel frame and the column, including the panelized metal ceiling structure described in Patent Document 1, the ceiling base panel frame and the column do not interfere with each other, and a plurality of ceilings are arranged around the column. As described above, the structural form of installing the base panel frame and reinforcing it with reinforcing materials, spacers, bridge hardware, etc. is applied. does not exist.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a ceiling base panel frame arrangement structure that is excellent in workability and that can effectively utilize the space at the top end of the pillar.

In order to achieve the above object, one aspect of the arrangement structure of the ceiling base panel frame according to the present invention includes:
A cross-shaped column head made of a steel plate in a plan view is provided on the steel frame column, and in a plan view, the corner portion of the grid-shaped ceiling base panel frame is positioned in the gap between the column head. It is characterized by

According to this aspect, in the configuration in which the cross-shaped pillar head formed of a steel plate in plan view is provided on the steel frame pillar, the corner portion of the ceiling base panel frame is positioned in the gap of the pillar head. As a result, the space at the top end of the pillar in plan view can be effectively utilized. Here, the grid-like ceiling base panel frame has a pair of main members, a plurality of connecting members connecting the main members facing each other, and auxiliary connecting members connecting the connecting members. As described above, the ceiling base panel frame is assembled in advance in a frame shape at a factory, and is a member that is transported to the site and installed as it is as a ceiling base.

The column head is formed by attaching steel plates assembled in a cross shape in plan view to the column head of a column such as a square steel pipe column. For example, a steel plate is formed in a cross shape in a plan view by welding and joining two steel plates perpendicular to the center position of one steel plate. For example, in the capital of a square steel pipe column that is square in plan view, the cross-shaped steel plate in plan view divides the area of the capital into four square regions. By positioning the corners of the four ceiling base panel frames arranged on the four sides of the pillar in each of the four square areas, the four ceiling base panel frames are positioned at the top of the column in plan view. are arranged so that the corners of the columns overlap, and the space at the top end of the column is utilized.

In another aspect of the arrangement structure of the ceiling base panel frame according to the present invention, the column head has a beam fixing plate on the steel plate, and a beam is fixed to the beam fixing plate,
The ceiling base panel frame is suspended from the beam via a hanging jig.

According to this aspect, the ceiling base panel frame is suspended via the hanging jig from the beam fixed to the beam fixing plate of the column head, thereby effectively utilizing the space at the top end of the column in plan view. It is possible to efficiently and stably fix the ceiling base panel frame to the beam while utilizing it. Here, the beams are floor beams on the upper floors that form the building frame together with the columns, and are formed of shaped steel materials such as H-shaped steel. The hanging jig consists of a hanging bolt that is bolted to the lower flange of the H-shaped steel forming the beam, and an engaging piece that is joined to the hanging bolt and engages with, for example, the main member of the ceiling base panel frame. etc.

In another aspect of the arrangement structure of the ceiling base panel frame according to the present invention, the ceiling base panel frame is made of steel.

According to this aspect, the main material, the connecting material, the auxiliary connecting material, and the like forming the ceiling base panel frame are all made of steel such as light iron, so that they are lighter than wooden members. It becomes a panel frame with excellent workability and excellent quality.

As can be understood from the above description, according to the arrangement structure of the ceiling base panel frame of the present invention, the workability is excellent, and the space at the top end of the pillar can be effectively utilized.
