Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a skeleton suitable for constructing a skeleton of a structure such as a building and a frame frame used for the method.

[0002]

2. Description of the Related Art Generally, in order to construct a building, particularly a high-rise building frame, a climbing type crane or the like is used.
Members, such as columns, beams, and floors, are suspended from the ground, and the building is sequentially stacked from the lower floors to the upper floors. However, in this method, the progress speed of erection of columns and beams depends on the capacity of the crane and the number of installed cranes, so it is difficult to significantly reduce the erection time. Further, since the work for constructing the pillars and beams and the slinging work requires manpower, each work at a high place is a dangerous work.

Therefore, a construction method using a construction device having a structure as shown in FIG. 7 has been proposed as a construction method for a building that solves such a problem (Japanese Patent Laid-Open No. 70844/1990). The construction apparatus used in this construction method is that a temporary beam assembly 1 is assembled above a building to be constructed, and a cylinder device 2 is vertically attached to a position of a main installation pillar of the temporary beam assembly 1, and the lower end of each cylinder device 2 is installed. The tip portion of the rod 3 that expands and contracts downward from is temporarily fixed to the upper end of each of the main columns 5 of the existing lower-floor frame 4 by bolts or the like, whereby the temporary columns are assembled. According to the construction method using this construction device, the rods 3 are simultaneously extended to horizontally lift up the temporary beam assembly 1, thereby securing the working space 6 having a height of one floor. After that, one rod 3 is lifted after releasing the temporary fixing of the tip end thereof,
Between the existing main pillar 5 and the existing main pillar 5, a new main pillar 8 lifted by the crane device 7 is inserted by the work robot 9,
The lower end of the main pillar 8 is joined to the upper end of the existing main pillar 5. Then, after the tip portion of the rod 3 is temporarily fixed to the upper end of the main pillar 8 again, the temporary fixing of the rod 3 is released for the remaining rods 3 to the joining of the main pillar 8 to the rod 3.
The steps up to the re-temporary fixing are sequentially repeated, whereby the construction of all main columns for the first floor is completed, and at the same time main beams and floor construction are performed, and the temporary beam assembly 1 is lifted again. By repeating the same steps as above, the building is gradually built up from the lower floors to the upper floors.

[0004]

However, in the conventional method of constructing a skeleton as described above, for example, only a part of the building to be constructed (hereinafter referred to as "core part") is surrounded by other parts. (Hereinafter, referred to as “peripheral portion”) When it is higher than the peripheral portion of the lower layer, the construction device cannot construct the core portion of the portion protruding above the peripheral portion of the lower layer. There is. Also,
For example, when the number of members to be built in only the core part of a building is concentrated, it takes time and effort to construct only this core part, so it is not possible to average the work of the core part and peripheral parts on each floor, Depending on the progress of each other's work, sometimes the work of both sides may be complicated or the waiting time may become long, resulting in not only poor work efficiency but also securing the number of workers. However, it was difficult to properly allocate personnel, and this was an obstacle to shortening the construction period. The present invention has been made in consideration of the above points, and an object of the present invention is to provide a method of constructing a skeleton and a frame structure used for the method of constructing a building efficiently to shorten the construction period. To do.

For example, one of the peripheral frames is located above the core part and the peripheral part by the difference in floor height, and these are integrally connected to form a frame frame. Under the condition that the frame is supported on a temporary pillar standing on the frame of the lower floor, below the core frame and the peripheral frame of the frame frame, the frame below the above frame is preceded. Then, follow the lower frame of the other frame to assemble the core and the peripheral frame respectively, and raise the temporary pillar by reacting to the frame of the lower floor to raise the core frame and the peripheral frame. The process of raising the frame, which consists of the frame and the frame, is repeated to build the core and peripheral frames up to the floor directly below the top floor. The frame to be constructed is constructed by placing the frame frame, that is, the core and the frame of the uppermost floor of the peripheral part on the upper surface and removing the temporary columns.

According to the second aspect of the present invention, the frame frame is arranged such that one of the core frame and the peripheral frame is arranged above, for example, by the difference in floor height between the core part and the peripheral part. The core frame and the peripheral frame are integrally connected by a vertically extending connecting member.

The cover 33 is stretched to integrally cover the core hat truss 16 and the peripheral hat truss 21 and to cover the outer peripheral surface of the cover frame 32. As a result, the spaces 35 and 36 inside and below the hat truss H are formed.
Is covered with the cover 33, and has a structure capable of preventing wind and rain at the construction site below the cover. Further, the lower surfaces of the core hat truss 16 and the peripheral hat truss 21 are provided with a transport mechanism (not shown) for transporting materials and the like in the lower spaces 35 and 36, respectively.

The hat truss H having the above structure
Are supported on masts (temporary columns) 39, 39, ... Equipped with a lift-up mechanism, which are erected on the main beams 15, 20 of the main body A of the lower floor which have already been assembled.
Beams 1 above and below each floor, vertically below each mast 39
5, 15 or the columns 40, 4 between the beams 20, 20.
0 is arranged, and the load of the hat truss H transmitted from the mast 39 is dispersed and transmitted to the skeleton A.

Next, a method of constructing the skeleton A using the above-mentioned hat truss H will be described with reference to FIGS. 1 to 6. First, as shown in FIG. 4 (a), a predetermined number of masts 39 are vertically erected at predetermined positions on the already-prepared foundation G, and the pillars 14,
The beam 15 and the like are assembled to form the core hat truss 16. Then, a transport mechanism (not shown) is attached to the lower surface of the core hat truss 16, and a cover (not shown) is stretched on the upper surface.

Next, as shown in FIG. 4 (b), below the core hat truss 16, the main pillar 1 of the core 11 is installed.
4, Assembling the beams 15, and each time the assembly for one floor is completed, the lift-up mechanism of each mast 39 applies a reaction force to the beams 15 of the main construction to make them climb at the same time, and the core part hat Lift up truss 16 for the first floor. By repeating this, the core portion 11 is set to a predetermined floor (the number of floors of the difference in floor height between the core portion 11 and the peripheral portion 12, for example, 5th floor)
Build up.

When the core portion 11 is constructed up to the predetermined floor, as shown in FIG. 5 (a), a predetermined number of masts 39 are vertically set at predetermined positions on the foundation portion G around the core portion 11. The pillar 19, the beam 20, the connecting beam 23 (see FIG. 2), etc. are assembled on the mast 39, and the peripheral hat truss 2 is installed.
1 is formed. The peripheral hat truss 21 and the core hat truss 16 located above the peripheral hat truss 21 are integrally connected by a predetermined number of connecting members 22 to form a hat truss H. The guide mechanism 25, 2 shown in FIG. 3 is provided at a position where the peripheral hat truss 21 and the core portion 11 face each other.
Attach 5, ... In addition, a transport mechanism (not shown) is attached to the lower surface of the peripheral hat truss 21, and a predetermined number of overhanging portions 30 are provided on the upper surface. No) is installed.

After this, as shown in FIG. 1, below the core hat truss 16, the main pillars 14 of the core portion 11,
While assembling the beam 15, in parallel with this, below the peripheral hat truss 21, the main pillar 1 of the peripheral portion 12 is installed.
9. Assemble the beam 20. Then, every time the assembly for one floor is completed, the lift-up mechanism of each mast 39 exerts a reaction force on the beams 15, 20 of the main construction to make them climb simultaneously, and the entire hat truss H for one floor. Lift up. At this time, the roller member 26 travels along the guide rail 27 of the guide mechanism 25 shown in FIG. 3, and the hat truss H can be smoothly lifted up. Further, the pillars 40 arranged below the respective masts 39 are lifted up to the upper parts of the masts 39 and are successively relocated upwards. On each floor, as described above, the assembling process of the core part 11 and the peripheral part 12 and the lift-up process of the hat truss H are repeated to construct the core part 11 and the peripheral part 12 up to the floor immediately below each uppermost floor. I will do it. Further, as the hat truss H is lifted up, the guide rail 27 of the guide mechanism 25 shown in FIG.
Are replenished upward as described above.

In this way, the core portion 11 and the peripheral portion 12
After constructing each of the floors up to the floor immediately below,
The transport mechanism (not shown) for the hat truss H, the cover 33, and the cover frame 34 shown in FIG. At this time, since the covering body frame 34 can be bent at each connecting portion of the unit frame 31, the detaching work can be easily performed. Then, each mast 39 is lowered, and the hat truss H is placed on the upper surfaces of the core portion 11 and the peripheral portion 12 that are constructed up to the floor immediately below the uppermost floor. Then, all the connecting members 22 are removed to divide the core hat truss 16 and the peripheral hat truss 21 and the peripheral hat truss 21.
The temporary connecting beam 23 is removed from. Then, the core hat truss 16 and the peripheral hat truss 21 are connected to the core portion 11 and the peripheral portion 12, respectively, and then the mast 39 is disassembled and removed. At this time, the hat truss H is composed of the uppermost floor portion 13 of the core portion 11 and the uppermost floor portion 18 of the peripheral portion 12, so that the core portion 11 and the peripheral portion 12 are constructed to the uppermost floor. (See FIG. 5B).

Thereafter, a crane or the like (not shown) is installed on the roof, and the roof floor 43, the outer peripheral portion 44, etc. are constructed using the crane, thereby completing the frame A to be constructed as shown in FIG. . Needless to say, in parallel with the construction of the skeleton A, exterior curtain walls, facilities, partitions, floor PC boards, etc. are sequentially installed from the lower floors. As described above, using the hat truss H, the lower part of this is, so to speak, a “factory”, and the construction of the skeleton A of the building in which the core part 11 projects above the peripheral part 12 and is a high-rise building is automatically performed. To do.

In the method of constructing the skeleton A described above, the core portion 1
The core hat truss 16 that constitutes the skeleton of the uppermost floor 13 of 1 is arranged above the peripheral hat truss 21 that constitutes the skeleton of the uppermost floor 18 of the peripheral portion 12, and these are integrally connected. The hat truss H is formed. In this way, by preliminarily assembling the core part 11 and the uppermost floor parts 13 and 18 of the peripheral part 12 on the ground in advance, the construction can be safely and efficiently proceeded. While the hat truss H is supported on the masts 39, 39, ..., the core part 11 is preceded and the peripheral part 12 is followed, and the process of dividing and assembling each of them is performed. After repeating the process of taking up reaction force to the beams 15 and 20 to lift the hat truss H up and stacking the core portion 11 and the peripheral portion 12 to the floor directly below the uppermost floor, the core portion 11, The hat truss H is placed on the peripheral portion 12 to construct the skeleton A of the building to be constructed. In this way, the work section is divided into the core portion 11 and the peripheral portion 12, the complicated core portion 11 of the construction is preceded, the peripheral portion 12 of the construction that is easy to follow is followed, and the construction is separately performed. Therefore, the work of the core portion 11 and the peripheral portion 12 can be averaged, the waiting time is not generated, and proper staffing can be performed. As a result, work efficiency is significantly improved. Therefore, the construction period can be shortened.

In addition, the above-mentioned hat truss H moves the core frame 16 upward from the peripheral hat truss 21 by, for example, 5 floors (a difference in floor height between the core portion 11 and the peripheral portion 12). When they are positioned, they are integrally connected by a connecting member 22, and the skeleton A is stacked and constructed under the structure. Thus, when the core truss 11 projects above the peripheral portion 12 to construct a high-rise building frame A, by applying the hat truss H, the core portion 11 and the peripheral portion 12 are respectively placed at the top. It is possible to construct up to the floor directly below the floor, place the core hat truss 16 and the peripheral hat truss 21 on it, and make it the top floor of the core portion 11 and the peripheral portion 12 as it is. It is possible to build efficiently. Moreover, when the hat truss H is lifted up, since the core hat truss 16 and the peripheral hat truss 21 are integrally connected, the work is compared with the case where these are separately provided and lifted up. In terms of facilities and equipment, it is possible to greatly improve efficiency. Further, since the hat truss H is supported by the masts 39, 39 on the existing beams 15, 20 on the lower floor, the spaces 35, 36 below the hat truss H are used as a factory. In addition, the hat truss H has a covering 33.
Since it is stretched, it is possible to prevent wind and rain, and it is possible to obtain a comfortable working space in all weather conditions. Furthermore, by disposing a machine room, a power room, a control room, and a work passage in the hat truss H and using these, workability and safety can be further improved. Further, on the hat truss H, at a position where the peripheral frame 21 and the core portion 11 face each other, a roller member 26 attached to the peripheral frame 21 side and a fixed member rewritably attached to the core portion 11 side. Since the guide mechanism 25 including the long guide rail 27 is provided, the lift-up operation of the hat truss H is guided thereby, and the hat truss H can be smoothly raised.
Moreover, with the lift up of the Hat Truss H,
By changing the guide rail 27 upward,
Work can be performed efficiently without providing a long guide rail.

In the above embodiment, the core portion 11,
Although the hat truss H is configured to be lifted up every time the peripheral portion 12 is constructed on the first floor, the construction is not limited to this, and may be constructed / lifted up on every second floor, every third floor, or the like. Further, in the above-described embodiment, the core hat truss 16 forming the hat truss H is located above the peripheral hat truss 21 by, for example, a height of 5 floors. After the construction up to the floor directly below is completed, this hat truss H is placed on the core portion 11 and the peripheral portion 12 as it is.
However, for example, when the core portion 11 is higher than the floor height of the peripheral portion 12 by 10 floors, etc., the core truss is constructed by using the hat truss H to build up to the floor directly below the uppermost floor of the peripheral portion 12. The truss 16 and the peripheral hat truss 21 are separated, the peripheral hat truss 21 is placed on the peripheral portion 12, and this is made the top floor of the peripheral portion 12, and then only the core hat truss 16 is lifted up. Alternatively, the core portion 11 may be constructed below the uppermost floor, and the core hat truss 16 may be placed thereon.
On the other hand, for example, the core part 11 and the peripheral part 1 of the building to be constructed
When 2 and the same floor height, contrary to the above, the core portion 11
When the building is built up to the floor immediately below the top floor, the core hat truss 16 and the peripheral hat truss 21 are separated, the core hat truss 16 is placed on the core portion 11, and the core hat truss 16 is placed on the core portion 11. After making it the top floor of 11, the peripheral hat truss 21 is lifted up, and the peripheral portion 12 is built up to the floor immediately below the top floor, and the peripheral hat truss 21 is placed on it. You can do it like this.
Further, in the above-described embodiment, the building to be constructed has a configuration in which the core portion 11 is located in the center portion and the peripheral portion 12 is located outside thereof, but the present invention is not limited to this.
It is needless to say that the same effect can be obtained even when is located on the outer peripheral portion of the building and the peripheral portion 12 is located inside thereof. Furthermore, the core hat truss 16
Is positioned above the peripheral hat truss 21,
Although the construction of the core portion 11 is performed first, the peripheral hat truss 21 may be positioned above the core hat truss 16 and the construction of the peripheral portion 12 may be performed first.

As described above, according to the skeleton construction method of the first aspect, one of the peripheral frame and the peripheral frame is moved upward by an amount corresponding to the difference in floor height between the core and the peripheral. At the same time, they were connected together to form a frame frame. In this way, by preliminarily assembling the core part and the uppermost floor part of the peripheral part on the ground in advance, it is possible to proceed with the work safely and efficiently. Then, in a state in which the frame frame is supported on a temporary pillar that is erected on the existing lower-floor frame, the frame located above the core frame and the peripheral frame of the frame Of the lower frame of the other frame, followed by the lower frame of the other frame to assemble the core and the peripheral frame respectively, and raise the temporary pillar by reacting to the frame of the lower floor. Repeating the process of raising the frame frame as a unit, and dividing the core part and the peripheral part up to the floor directly below the uppermost floor, place the frame frame on the upper surface of the frame and remove the temporary column By doing so, the core and the uppermost floor of the peripheral part are configured on the upper surface of the skeleton to construct the skeleton to be constructed. In this way, the work section is divided into a core portion and a peripheral portion, and one of them is preceded and the other is followed, so that the construction is performed separately, so that the work of the core portion and the peripheral portion can be performed. The averaging can be achieved, the waiting time is not generated, and proper staffing can be performed. As a result, work efficiency can be significantly improved, and the work period can be shortened.

According to the frame frame of the second aspect, the frame frame is arranged above either the core frame or the peripheral frame by an amount corresponding to the difference in floor height between the core frame and the peripheral frame. At the same time, these are integrally connected by a connecting member, and the core and the peripheral body are divided and assembled under the structure. This allows
For example, when the method of constructing a skeleton according to claim 1 can be realized, and the skeleton of the building to be constructed has a high-rise structure in which one of the core portion and the peripheral portion projects higher than the other. However, by applying this frame frame, after the core part and the peripheral part are respectively constructed up to the floor directly below the top floor, the frame frame is placed on the core part,
It can be the uppermost floor of the peripheral part, and the structure can be efficiently constructed. Moreover, when the frame frame is lifted up, since the core frame and the peripheral frame are integrally connected, compared to the case where these are provided separately and lifted up, in terms of work and equipment, Greatly improved efficiency can be achieved. Also, with the temporary pillars provided in the frame frame, the frame frame is supported on the existing lower-floor frame body, and the core part and the peripheral frame parts are separately assembled below that, so the lower part of the frame frame The space can be used as a factory. Further, by covering the periphery of the frame with a cover, it is possible to prevent wind and rain, and it is possible to obtain an all-weather comfortable work space. Moreover,
If a machine room, a power room, a control room, and a work passage are arranged and used in the frame, the workability and safety can be further improved.

According to the frame structure of the third aspect of the present invention, a guide mechanism is provided on the frame frame side at a position where the frame frame and the existing lower-floor frame body are opposed to each other, and the guide mechanism is vertically movable relative to each other. The rotatable roller member is provided, and a rail member that extends in the vertical direction and is fixedly attached to the side of the body of the lower floor so that it can be refilled. As a result, when the frame frame is lifted up, the roller member on the frame frame side runs along the rail member on the frame side of the lower floor, and the lift-up operation of the frame frame is guided, so that the frame frame moves smoothly. Can be lifted up. Also,
By reassembling the rail member upwards as the construction of the skeleton progresses, it is not necessary to provide a long rail member or the like, so that the work can be performed efficiently.

A method of constructing a skeleton, comprising: a core frame that constitutes a skeleton of a top floor of a core of a structure to be constructed; and a skeleton of a top floor of a peripheral portion around the core. One of the peripheral frames to be positioned above is positioned above and these are integrally connected to form a frame frame, and the frame frame is provided with a lift-up mechanism erected on the existing lower-floor frame. In a state where the frame is supported on a temporary pillar, below the core frame and the peripheral frame of the frame, the lower frame of the frame located above the preceding frame is preceded, and the lower frame of the other frame is advanced. The following steps are repeated: assembling the core part and the peripheral part of the skeleton of the skeleton, and raising the temporary frame by raising reaction force to the skeleton of the lower floor to raise the frame. After stacking and building the core part and the peripheral part of the skeleton to the floor directly below the uppermost floor of each of the core part and the peripheral part, placing the frame frame on the upper surface of the skeleton to remove the temporary pillars. A method of constructing a characteristic skeleton. 2. A frame for constructing a frame on the uppermost floor of a structure to be constructed, which is provided with main columns and beams, and a frame for constructing a frame for a lower floor below these columns, which is a frame. One of the core frame that constitutes the body of the uppermost floor of the core portion and the peripheral frame that constitutes the body of the uppermost floor around the core portion is arranged above, and these core frame and The peripheral frame is configured to be integrally connected with a vertically extending connecting member,
In addition, the frame frame is provided with a temporary column that supports the frame frame on an existing lower-floor frame and has a lift-up mechanism that lifts by raising a reaction force to the frame. A characteristic frame frame. 3. The frame frame according to claim 2,
A guide mechanism is provided at a position where the frame frame and the frame of the lower floor are opposed to each other, and the guide mechanism is configured to be relatively movable in the vertical direction. The guide mechanism is a rotatable roller member provided on the frame side. And a rail member of a fixed length, which extends in the up-down direction and is removably attached to the frame side of the lower floor.
