Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building construction method and a building construction apparatus capable of constructing a building without being affected by the weather.

[0002]

2. Description of the Related Art Conventionally, an air dome suitable for temporary construction described in Japanese Patent Laid-Open No. 4-149380 is known as an auxiliary tool for building construction of this type (see FIGS. 11 and 12).

[0003] This example is an air dome tent having a main body having an airtight chamber filled with air formed therein and protruding upward when the air is filled. It is provided in an appropriate place of the tent, and is for fixing the both ends of the air dome tent to temporary scaffolds to cover the upper part of a building such as a building and to construct this covered area.

Incidentally, 1 in FIGS. 11 and 12 is a building,
2 is an air dome tent, 2a is a main body, 3 is a joining sheet,
4 is a rope, 5 is a parent rope, and 6 is a scaffold for temporary construction.

[0005]

Conventionally, as described above, since the upper part of the building is simply covered by the air dome tent with both sides (front and rear sides in FIG. 11) open, when the wind and rain are severe. It has been a problem that wind and rain penetrate into the air dome tent from both sides of the air dome tent, and the inside of the covered area is exposed to the wind and rain, making it impossible to construct.

Also, since only the longitudinal ends of the air dome tent are fixed to the temporary scaffolding, the air dome tent is easily swayed in the front-rear direction (front-rear direction in FIG. 11). There was a problem that the air dome tent could be scattered from the building due to the looseness (release) of the fixing to the scaffold.

Further, since the air dome tent can be connected only in the width direction side and cannot be connected in the length direction side, in the case of a building having a peculiar shape, for example, a plane cross shape, the central portion Is divided into either the vertical direction or the horizontal direction, it is impossible to construct the divided part, it is impossible to convert to various buildings, and various types of air dome tents can be used for various buildings. It was necessary to prepare it, and the problem was that inventory management was complicated.

Further, the air dome tent only covers the upper part of the building and it is impossible to reinforce the building.

In view of such drawbacks, it is an object of the present invention to provide a building construction method and a building construction apparatus capable of reliably covering the upper part of the building and improving the strength of the building. To do.

[0010]

In the building construction method of the present invention, in building construction, a detachable waterproof sheet is attached to the surface above the building, and the covering frame is inclined downward from the center toward both ends. After sequentially positioning a plurality of them by the elevating mechanism, each covering frame is connected and fixed while interposing a connecting pipe already built on the building floor of the building and a new connecting pipe, and connecting each covering frame respectively. After constructing the area covered by each covering frame, release the fixing of each covering frame and the connecting pipe, release each connection of each covering frame, and raise each covering frame sequentially by the elevating mechanism. After letting
It is characterized in that a building is constructed by connecting the covering frames again by interposing a new connecting pipe and connecting the covering frames to construct a covering area.

Further, in the building construction apparatus of the present invention, a plurality of covering frames each having a waterproof sheet detachably attached to the surface of a frame body which is slanted downward from the center toward both ends are sequentially moved up and down by an elevating mechanism. It is characterized by that.

[0012]

A description will be given based on FIG.

A waterproof sheet 12 is detachably attached to the surface of the frame body 10 which is inclined low from the center toward both ends. In this embodiment, the frame body 10 is made of one kind or a plurality of kinds of pipe materials, is formed in a roof shape, and sequentially connects the pipe materials corresponding to the area of the building floor surface 16 of the building 14 to be built, The size can be changed by removing it.

Further, the reason why the frame body 10 is formed in a roof shape is to prevent rainwater that has fallen on the frame body 10 from being carried out downward and prevent rainwater from collecting on the frame body 10. .

Further, the waterproof sheet 12 is a rectangular type,
The material is natural latex, neoprene, or the like.

The connection between the waterproof sheets 12 is as shown in FIG.
As shown in FIG. 5, a coupling joint 20 having a coupling hole 18 penetrating is provided at each longitudinal end of each waterproof sheet 12.
A connecting bolt 22 is inserted through the connecting hole 18, and a nut 24 is screwed into the connecting bolt 22 so as to be fixed and connected.

The lateral direction of the waterproof sheet 12 and the frame 10
6 and 7, the waterproof sheet 12 is wound around one pipe member of the frame body 10 and fixed by a fixture 19 such as a string, and the adjacent pipe members are connected to each other as shown in FIGS. 6 and 7. The waterproof sheet 12 is wound and fixed on the pipe material, and the surface thereof is covered with a connecting sheet 26.

A covering frame 30 is composed of the frame 10 and the waterproof sheet 12, and the covering frame 30 has a width which is a fraction of the construction floor surface 16 of the building 14, and is composed of several covering frames 30. The upper part of the building 14 is covered.

For example, assuming that the covering frame 30 has a width of 1/10 of the construction floor surface 16 of the building 14, ten covering frames 30 can cover the upper part of the building 14.

As shown in FIGS. 1 and 2, the covering frame 30
Elevating mechanism 32 is provided. In this example,
The lifting mechanism 32 is a mobile crane.

A connecting pipe 34 for connecting to the covering frame 30 is shown in FIGS. 1 and 8 to 10. The connection pipe 34 of the present embodiment is a hollow single pipe, and the connection and fixation with the covering frame 30 is performed by a joint pipe 38 having a fixing hole 36 and a fixture 40 rotatably provided on each connection pipe 34. The fixing tool 40 of each connecting tube 34 is inserted into the fixing hole 36 of the joint tube 38, and the fixing tool 40 is rotated to fix the both.

In the figure, 42 is a lifting hook of the lifting mechanism, 44 is a lifting wire, 46 is a wire attached to the covering frame 30, 48 is concrete, and 50 is a connecting portion of the covering frame 30. Show.

A construction method for constructing a building using the building construction apparatus of this embodiment will be described with reference to FIGS.

First, a fraction of the construction floor surface 16 of the building 14
A plurality of covering frames 30 are formed in correspondence with the width of the. In this embodiment, since the frame body 10 is made of pipe material, by using the pipe materials in combination, the frame body 10 is formed into a roof shape corresponding to a width of a fraction of the construction floor surface 16 of the building 14. Let At this time, the waterproof sheet 12 is attached to the surface corresponding to each covering frame 30.

Next, each covering frame 30 is sequentially positioned above the building 14 (upper part of the building floor 16) via the elevating mechanism 32.

At this time, in the present embodiment, each covering frame 30
Although the connection between the elevating mechanism 32 and the elevating mechanism 32 is performed by the wire 46, it is also possible to attach a hook (not shown) to each covering frame 30 and directly connect the hoisting hook 42 of the elevating mechanism 32 to this hook. .

Next, each of the covering frames 30 is connected to the connection pipe 34 already constructed on the construction floor surface 16 of the building 14 and a new connection pipe 34.
Connect and fix via. At this time, the two connecting pipes 34 are connected and fixed by the joint pipe 38 and the fixture 40.

Here, when the first floor of the building 14 is constructed, since the connecting pipe 34 is not disposed on the floor surface on which the foundation work has been carried out, the connecting pipe 34 is erected via a support tool (not shown) or the like. It is necessary to support the installation.

Next, the covering frames 30 are connected to each other. At this time, the connecting means is not particularly limited.

Next, the area covered by each covering frame 30 is constructed.

At this time, in order to carry in the materials necessary for construction from the ground, a lifting device (not shown) such as a crane installed in the covered area is used, and the waterproof sheet 12 at the carrying-in portion is used.
Is removed from each covering frame 30 and carried in from that portion.

After the construction, there is no problem if the connecting pipe 34 is buried in the pillar of the building 14, but the connecting pipe 34 is not included in the building 1.
When buried in the wall of No. 4, the concrete layer that is cast near the buried connecting pipe 34 becomes thin, which easily causes cracks (reduced strength). By disposing the wire net 28, cracking is prevented. In this embodiment, the reinforcing wire mesh 28 has a width of 1
It is a wire mesh with a length of m and a length almost equal to the height of the first floor of the building 14.

After the construction is completed, the connection and fixation between the respective covering frames 30 and the connecting pipes 34 are released, the respective connecting parts of the respective covering frames 30 are released, and the respective covering frames 30 are sequentially moved upward through the elevating mechanism 32. To move.

The covering frames 30 moved again are connected and fixed above the building 14 via new connecting pipes 34, and the covering frames 30 are connected to each other to construct the area covered by the covering frames 30. To do.

By repeating this work in sequence, the building 14 is constructed so as to face upward.

After the construction of the building is completed, by removing the waterproof sheet 12 and disassembling the frame body 10 (a plurality of connected pipe members), each covering frame 30 can be removed, transported and used for the next use. Can also be reused.

Further, the connecting pipe 34 used in the present invention is embedded in the building 14 after the building is constructed.
Of the hollow connecting pipe 34
The strength of the building 14 can be further improved by inserting the grout agent therein.

Further, since the connecting pipe 34 is hollow, by inserting a sensor for seismic resistance test into the connecting pipe 34 embedded in the building 14, data collection such as stress analysis of the building at the time of earthquake can be prolonged. Can be done over a period of time.

Although the covering frame 30 used in the building construction method of the present invention is composed of the frame body 10 made of a plurality of pipe materials, it is obvious that it can be composed of one frame body. The lifting mechanism 32 is a crane truck,
Any other mechanism such as a tower crane that can be raised and lowered can be used.

Further, although there are a plurality of covering frames 30 used in the building construction method of the present invention, if the building to be constructed is small, it is possible to construct with one covering frame 30. It is self-evident that the work of connecting the covering frames 30 to each other is eliminated and the construction time can be shortened.

Further, by attaching an advertisement to the outer surface of each covering frame 30 according to the present invention, it can be used as an advertisement display tool for the neighborhood when a building is being constructed.

[0042]

According to the building construction method and the building construction apparatus of the present invention, the upper part of the building can be surely covered by the plurality of covering frames, so that the building can be constructed without being affected by bad weather. .

Further, since each connecting pipe is buried in the building after construction, the strength of the building can be improved.

Further, since the covering frame is slanted downward from the center toward both ends, it guides the rainwater that has dropped onto the covering frame downward and prevents rainwater from collecting on the waterproof sheet mounted on the covering frame. can do.

The building construction apparatus has a simple structure,
Since it is easy to transport, the construction period for building can be shortened and the construction cost can be drastically reduced.

Further, when the connecting pipe is buried in the wall of the building after construction, it is likely to cause cracks (decrease in strength). Therefore, by disposing a reinforcing wire mesh near the connecting pipes, the cracks are prevented. Can be prevented.
