DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building support structure for supporting a building constructed by a traveling method in which a building constructed while being supported on a rail member is sent out along the rail member.

[0002]

2. Description of the Related Art A traveling construction method is used in an area where there are many restrictions on the working time, the place of lifting, and the like, for example, when a building is to be added above a building such as a station square where traffic is heavy. When the building is extended on the existing building by the traveling method, a steel crane is lifted by a tower crane or the like on the roof at one end of the existing building, and one block is placed on the rail member extending to the other end of the existing building. Build a steel frame. The constructed steel structure of one block is moved to the other end side by a traveling device constituted by a hydraulic cylinder or the like, and the next block is constructed again at the original place and moved again.

[0003] By repeating the construction and the lateral movement for each block, a building can be constructed on an existing building. After the construction of the building, the pillars of the new building are supported on the existing building by removing the rail members.

[0004]

However, the work of removing the rail member requires a relatively long and time-consuming operation such as pulling out the rail member and lowering the building again with the additional building jacked up. It is.

The present invention has been made in view of the above circumstances, and has as its object to obtain a building support structure capable of improving work efficiency by omitting removal work of a rail member for lateral transfer guidance.

[0006]

The invention according to claim 1 is based on a traveling construction method in which a constructed building is sent to a predetermined position along the rail member while being supported on a rail member laid on an existing support. A building support structure for supporting a built building, wherein a rail portion other than a portion for supporting a built-in post of the building at the time of sending out is removed, and a rail member for supporting a built-in post is provided. The structure is characterized in that a shield plate is attached so as to surround the column and the column in the building is connected to the existing column.

[0007]

According to the first aspect of the present invention, the constructed building is moved to a predetermined position along the rail member laid on the existing support. When the building reaches a predetermined position, the rails other than the part supporting the internal column of the building are removed.

Accordingly, the work for removing all the rail members, for example, the jack-up of a building is not required, and the workability is improved.

Next, shield plates are attached to the four sides of the remaining rail member to close the gap, and connect the column in the building to the existing column. With this shielding plate, the remaining rail members can be shielded.

[0010]

FIG. 1 shows the appearance of a building 10 constructed by the traveling method. This building 10
Is added to the roof of the existing building 12.

Briefly describing the traveling method, a rail member 14 is disposed on a roof 12A of an existing building 12 in a lateral direction of FIG. The steel frame is lifted by a tower crane or the like (not shown) on the rooftop on the right end side of FIG. 1 of the existing building 12, and the steel frame is assembled in the yard B shown in FIG. . Next, the traveling device 18 driven by a hydraulic cylinder or the like is operated to move the steel frame construction 16 constructed in the yard B to the adjacent yard C along the rail member 14 (the direction of arrow A in FIG. 1). In the yard C, construction work for applying the exterior 20 of the constructed steel frame building 16 is performed.

One block of the building 10 on which the exterior work has been completed in the yard C is further sent to the left end side in FIG. By sequentially repeating this, an additional building 10 can be constructed on the existing building 12. The steel frame 16 constructed in the yard B is connected to the end of the steel frame 16 in the yard C that has already been laterally moved.

Here, as shown in FIGS. 2 to 4, on the roof 12A of the existing building 12, an H-beam
6 are stacked in two stages. That is, the rail member 1
4 is laid on the two-tiered H-beam 26. Here, a box-shaped base 24A is attached to the upper part of the column 24 so as to coincide with the uppermost surface height of the H-shaped steel 26, and the rail member 14 is mounted on the column 24 via the box-shaped table 24A. Will be.

The rail member 14 is made of a T-shaped steel, provided with rib plates 14A at predetermined intervals in the longitudinal direction, and has a strength substantially equal to that of the H-shaped steel 26. The rail member 14 is left as it is even after the construction of the building 10 is completed.
The rib plates 14A are provided at narrow intervals, and have higher strength than other portions (removed portions).

As shown in FIG. 2, since the rail member 14 is continuously laid in the lateral direction of the existing building 12, the rail members other than the portions sandwiched by the columns 22, 24 are provided. The member 14 (the area whose outer periphery is surrounded by a grid-like hatched line in FIG. 2) has been removed together with the H-shaped steel 26 by cutting after the final lateral movement.

As a result, a gap 27 (see FIG. 3) is formed between the support 24 of the existing building 12 and the support 22 of the additional building 10 because the rail member 14 remains. A shielding plate 28 is welded to the remaining four gaps of the rail member 14 so that the columns 22 and 24 are continuous. Thereby, the support 24 of the existing building 12 is
The support 22 of the additional building 10 is connected to the support 22 by a shielding plate 28 so as to support the load together with the rail member 14.

The operation of this embodiment will be described below. On the roof 12A of the existing building 12, an H-beam 2
6 are stacked in two stages. The rail member 14 is fixed to the uppermost portion of the H-shaped steel 26 and laid in the lateral direction in FIG.

In the yard B, a steel frame is lifted by a tower crane, and the steel frame is assembled on the rail member 14 to construct a one-frame steel frame construction 16. Next, the traveling device 18 is operated, and the steel framing 16 constructed in the yard B is moved along the rail member 14 to the adjacent yard C, and exterior construction of the constructed steel framing 16 is performed. At this time, in the yard B, a new steel frame style 16 is constructed and connected to the steel frame style 16 located in the yard C.
By repeating this, an additional building 10 can be sequentially constructed on the existing building 12.

When all the constructions are completed, the H-section steel 26 is removed, and portions of the rail member 14 other than those supporting the columns 22 of the additional building 10 are removed by cutting. That is, the rail member 14 provided between the column 24 of the existing building 12 and the column 22 of the additional building 10 remains as it is.

Next, a shielding plate 28 is provided so as to bridge between the columns 22, 24 corresponding to the four sides of the remaining rail member 14.
By welding, the load of the additional building 10 can be supported not only by the rail member 14 but also by the shielding plate 28.

Also, as in this embodiment, by connecting the column 22 and the column 24 via the shielding plate 28, even if the axis of the column 22 and the axis of the column 24 are slightly deviated, the shielding plate Only the inclination at the time of installation of 28 changes,
The two sides of the support 2 and the four sides of the column 24 can be continuous.

As described above, by leaving a part of the rail member 14 applied for the traveling method even after the completion of the construction, the additional building 10 is jacked up and all the rail members 14 are removed. Furthermore, the work of jacking down can be omitted, and the work efficiency is improved.

In this embodiment, the four sides of the rail member 14 remaining between the columns 22 and 24 are only shielded by the shield plate 28. However, concrete may be driven into this shield inner space.

[0024]

As described above, the building support structure according to the present invention has an excellent effect that the work efficiency can be improved by omitting the work of removing the rail member for transit guide.
