DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a building for constructing a bridge or the like by passing over existing facilities such as a house and a road.

[0002]

2. Description of the Related Art Conventionally, in order to erection of a building passing over existing equipment, a method of firstly lifting a girder assembled on the ground using a crane or the like, and a second method of cantilevering a beam. And a third method is to extend the beam supported by extruding it by a fixed span, and thirdly, to extend the beam while supporting the member using a shoring.

[0003]

However, in the above-mentioned method of lifting and erection, it is difficult to construct a large span girder, and the function of the existing equipment is temporarily stopped. It is necessary to evacuate temporarily and stop the traffic if the existing facilities are roads, etc., which has a negative effect on social life. Further, according to the hand-rolling method, there is a problem that the time required for the erection is long, and even in this case, the temporary evacuation and the traffic stop are required. Further, according to the method using the shoring, there are inconveniences such as installation and dismantling of the shoring. Moreover, in any of the conventional techniques, there is a possibility that existing equipment may be damaged due to a drop of a part or the like during construction.

Accordingly, an object of the present invention is to reduce the work on existing equipment as much as possible to prevent the function of existing equipment from being stopped, to simplify the construction, and to shorten the construction period. I have.

[0005]

According to the present invention, there is provided a method for constructing a building, comprising: a step of forming a sector on a ground building installed on the ground near an existing facility by forming a sector having a front and back surface having a radius larger than the width of the above-mentioned ground structure. From the point of the first, the two continuous side faces each have a quadrilateral shape, and the arc surface has the same width as the quadrilateral.
Of the second sector piece of the same shape on the side surface of the quadrilateral shape of the sector piece after hanging the arc-shaped surface downward by gravity at the pivot of the sector piece. By suspending in the same manner with the side surfaces in contact with each other, the combined center of gravity of the two sector-shaped pieces is lowered below the pivot by gravity, and the third and subsequent sector-shaped pieces are similarly sequentially added and suspended. A plurality of fan-shaped pieces constitute an upper surface structure having a semicircular shape on the front and back surfaces and an upper surface projecting from the above-ground structure to form a plane, and the upper structure is non-rotatably fixed to pass over the existing facility. Things.

[0006]

[Function] Since the sectoral piece is pivotally supported on the ground structure at the point, the sectoral piece is suspended by its own weight and the arc surface faces downward. If the sectoral piece is pivotally supported at the same position and sequentially increased, A fan-shaped piece group composed of a plurality of suspended fan-shaped pieces is in a state in which the angle of the fan-shaped pieces is enlarged, and when the number of the fan-shaped pieces reaches a predetermined number, the whole becomes a semicircle and the center of gravity is at the pivot position. In order to be below, the upper surface becomes a flat sky structure. In this state, the aerial structure extends beyond the width of the above-ground structure and covers the existing facilities on the ground, and in this state, the sector-shaped pieces are fixed to the above-ground structure or installed adjacent to the above-mentioned structure. A building that passes over the existing equipment is constructed by fixing it to a similar fan-shaped piece group so as not to turn.

[0007]

FIG. 1 is a view showing an example of a building constructed by the method of the present invention. A ground-based building 2 such as a high-rise building, a tower, etc. is sandwiched between existing facilities 1 such as a house, a plaza, a road, and a railroad. Are constructed, and an overhead structure 3 is provided on each ground structure 2. A concave bearing 2a is formed at the upper end of the ground structure 2, and the horizontal shaft 2b is rotatably supported on the bearing 2a. Further, a recess 2c penetrating in the width direction is formed in the ground building 2, and the sky structure 3 is interposed here.

The sky structure 3 has a shape larger than the width of the ground structure 2 as shown in FIG. 1A and has a semicircular shape, and has a predetermined thickness as shown in FIG. A horizontal plane 3a is formed on the upper surface, and this is supported by the horizontal axis 2b to fix the two sky structures 3 together.
Alternatively, by means such as fixing between the ground structure 2 and the sky structure 3, each of the sky structures 3 is prevented from turning with respect to the ground structure 2. Bearing part 2 of both ground structures 2
The space between the horizontal shafts 2b supported by a has the same size as the diameter of the overhead structure 3, and therefore, the planes 3a on the upper surfaces of both overhead structures 3 are continuous. Thus, the two sky structures 3 pass over the existing facility 1.

Next, a procedure for constructing the semicircular sky structure 3 will be described with reference to FIGS. First, FIG.
As shown in (1), one of the sector-shaped pieces 4 (first sector-shaped piece) is hung on the horizontal axis 2b of the ground construction 2 at the pivot 4a. The fan-shaped piece 4 has the shape shown in FIG. 6, and the front and back surfaces 4b and 4c have a fan-shaped shape having a radius larger than the width of the above-ground structure 2.
The four side surfaces 4d and 4e each form a quadrilateral, and the arc surface 4f
Have the same width as the quadrilateral. Here is fan-shaped piece 4
Is simply described by the shape of the outer shell.
Since it constitutes the sky structure 3 as will be described later, it has a structure corresponding to the purpose of residence or walking of a person according to its use.

Next, as shown in FIG. 3, a second sectoral piece is brought into contact with one side face of the sectoral piece.
This fan-shaped piece is also suspended from the horizontal shaft 2b. Then, since the center of gravity of the group of both fan-shaped pieces is directly below the horizontal axis 2b, the first fan-shaped piece turns and balances.
Next, as shown in FIG. 4, a third sectoral piece is similarly added to the side surface of the second sectoral piece, and thus the addition and rotation of the sectoral piece 4 are repeated to obtain a predetermined number n. The sky structure 3 is constituted by the sector-shaped pieces 4 as shown in FIG. For connecting the sector-shaped pieces 4 to form the sky structure 3, known fixing means such as a fixing jig and a tension wire rope are used.

In this way, the building shown in FIG. 1 is constituted by the above-ground structure 2 and the above-mentioned sky structure 3, and FIG. 7, FIG. 8, and FIG.
Then, 3 sky structures 3 for one ground structure 2
Are arranged coaxially, and a pair of such ground structures 2 are arranged as shown in FIG. Here, a concrete plate 5 or the like is laid on the upper surfaces of the ground structures 2 and the sky structures 3 to form a continuous roof, and an additional structure 6 is added between the ground structures 2 to provide a space between the sky structures 3. The space is being used. The additional structure 6 can be constructed by suspending necessary members from the already constructed aerial structure 3 without having to provide a shoring on the ground below. Thus, the building can be constructed by the ground structure 2, the sky structure 3, and the additional structure 6 without stopping the function of the existing facility 1.

In the case of the buildings shown in FIGS. 7, 8 and 9,
The ground structure 2, the sky structure 3, and the additional structure 6 are naturally designed in advance so that their interiors can be used for living rooms, offices, stores, event squares, and the like. In addition, it is needless to say that the upper surface of the concrete plate 5 of the roof can be used for a square or other purposes.

In each of the above examples, the case where the pair of the ground structure 2 and the sky structure 3 supported by the ground structure 2 is paired so that the sky structures 3 are continuous at the ends is described. May be unpaired,
Of course, three or more sets may be configured to be continuous.

[0014]

As described above, according to the present invention, the overhead structure is gradually expanded on the existing facility while being supported by the above-ground structure near the existing facility. The danger of falling objects does not extend to existing facilities such as houses and roads. In addition, since the overhead structure is extended above the existing equipment by turning the fan-shaped pieces, there is almost no work on the existing equipment, and the use of ground-based structures as a scaffold for the production of the overhead structure. Therefore, it is possible to omit a scaffold only for the purpose of manufacturing the sky structure. Furthermore, when another structure is added to the overhead structure, the ground structure or the overhead structure can be used as a scaffold, so that a special scaffold for the another structure is not required. Thus, according to the present invention, it is possible to reduce the work on existing facilities as much as possible to avoid danger, and to shorten the construction period and reduce the cost.
