Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a erection method in which a roof portion is assembled on a concrete foundation, this portion is pushed up by a unloading device, and then a wall shaft assembly, an outer wall material and the like are assembled in the space.

[0002]

2. Description of the Related Art As a construction method of a prefabricated house, for example, a construction method is known in which a building is assembled while hoisting building materials with a truck crane.

[0003]

However, when construction is carried out in a residential dense area or in a place where the approach road is narrow, there are cases where the truck crane cannot be used.

[0004]

The erection method of the present invention uses a unloading device in which a roof part is finished on a shed beam placed on a concrete foundation and the finished roof part is arranged in an outer peripheral foundation. Are lifted to a predetermined position, and a wall shaft assembly, an outer wall material, and the like are assembled between the roof portion and the concrete foundation.

Further, a floor beam and a shed beam are placed in order from the bottom on a concrete foundation, and the roof portion is finished on the shed beam placed on the concrete foundation in this way, and the finished roof portion is Lift to a predetermined position using the unloading device arranged in the outer peripheral foundation, form a building upper part by assembling a wall shaft assembly, outer wall material, exterior material, etc. between the roof part and floor beam, and form this building upper part. The hoisting device is again placed in the outer peripheral foundation to lift it to a predetermined position, and the wall shaft assembly and the outer wall material are assembled between the floor beam and the concrete foundation.

[0006]

[Operation] After assembling the roof on the concrete foundation,
This is a erection method in which the roof is lifted to a predetermined position by an unloading device arranged in the outer peripheral foundation, and a wall shaft assembly, an outer wall material and an exterior material are assembled between the roof portion and the floor beam or the concrete foundation.

According to this erection method, it is possible to construct a building safely because it does not require work at high places.

Since no scaffolding equipment is required, the construction cost can be reduced.

Further, since the unloading device is arranged in the outer peripheral foundation, it is possible to easily construct a building in a narrow space surrounded by the unloading device, and even during construction, for example, piping work around the building. Can be performed in parallel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the construction method according to the present invention.

A floor beam 3 on the second floor is placed on a concrete foundation 1 through a temporary material 4 which is a spacer, and a shed beam 2 is further mounted on the floor beam 3 through a temporary material 4 which is a spacer. It is placed (see Fig. 2).

When the roof portion A1 is assembled or the finished roof portion A1 is raised, if there is a problem with the strength of the shed beam 2 alone, a reinforcing beam is used. Temporary reinforcement tension may be used instead of the shed beam 2. In this case, the reinforcing beam lifts the finished roof part A1 to a predetermined height,
After assembling the wall framing between 1 and the floor beam 3, this reinforcing beam is removed.

The temporary member 4, the floor beam 3, the reinforcing beam or the hut beam 2 are made of H-shaped steel, and each one has a height of about 200 mm.
Is. 21 is a beam connection.

The temporary member 4 used between the concrete foundation 1 and the floor beam 3 or between the floor beam 3 and the reinforcing beam or the shed beam 2 is not an essential component.

Reinforcing beams or hut beams 2 are about 100 above the ground.
It is placed in the place of 0mm-1500mm. In this state, at least four places of the reinforcing beam or the hut beam 2 are supported by the unloading device 100 arranged in the outer peripheral foundation 11 (see FIGS. 1 and 2).

According to the erection method of the present invention, the unloading device 10 is constructed by sequentially assembling the finished roof part A1 on the concrete foundation 1 and finishing it, and arranging the finished products in the outer peripheral foundation 11.
It is characterized by using 0 to raise it to build a building.

The unloading device 100 is preferably a multi-stage telescopic type and may use either hydraulic pressure or mechanical force. 10
Reference numeral 1 is a base of the unloading device 100.

The roof portion A1 is assembled on the reinforcing beam or the shed beam 2 thus supported by the unloading device 100. By supporting the reinforcing beam or the hut beam 2 with the unloading device 100, the bending of the reinforcing beam or the hut beam 2 when the roof portion A1 is assembled is prevented.

As for the structure of the roof portion A1, for example, a truss 23 is erected on the reinforcing beam or the hut beam 2, and a climbing beam 24 arranged on the truss 23 is covered with a field plate and a roofing material 25.

In the embodiment shown in FIGS. 1 and 2, a reinforcing beam is used. The reinforcing beam is obtained by lifting the finished roof part A1 to a predetermined height, and assembling a wall shaft assembly or the like between the roof part A1 and the floor beam 3 and then removing it. However, in order to eliminate this kind of removal work, the shed beam 2 with high strength
May be used to kill.

After assembling the roof part A1 on the concrete foundation 1, the finished roof part A1 is raised to a predetermined height by using the unloading device 100 (see FIG. 3).

In this state, a wall shaft assembly of the building upper part A2 (second floor portion) and exterior materials such as the outer wall material 50, the balcony 51, and the window frame sash 52 are assembled between the shed beam 2 and the floor beam 3.

When the assembling work of the building upper part A2 is completed, the unloading device 100 which has been supported is once removed. Also remove the reinforcement beams.

Next, the unloading device 100 is set so as to support the floor beam 3 from below. At this time, if there is a problem with the strength of raising the building upper part A2 only with the floor beam 3, the reinforcing beam may be arranged below the floor beam 3 again. Then, the unloading device 100 is set via this reinforcing beam, and the building upper part A2 is lifted.

After the building upper part A2 is lifted up to a predetermined height by using the unloading device 100, the wall framing of the building lower part A3 (first floor portion) and the outer wall material 60 are provided between the floor beam 3 and the concrete foundation 1. Building A4 by installing window frame sash 61 etc.
To complete.

The embodiment shown here is a building A2 with a second floor.
However, it goes without saying that this construction method can be applied to the construction of a building with two or more floors.

Further, the erection method of the present invention can be applied to a one-story building. This erection only requires the construction method shown in FIGS. 3 and 4.

[0028]

EFFECTS OF THE INVENTION According to this erection method, it is possible to construct a building safely because it does not require work at height.

Since the unloading device is arranged in the outer peripheral foundation, it is possible to simultaneously perform the plumbing work around the outside of the building even when the building is being constructed, and the building can be constructed even in a narrow land. it can.

Since a truck crane is not used, it is suitable for construction in a dense residential area or a place with a narrow approach road.

Since the building can be assembled entirely on the concrete foundation, temporary equipment such as safety nets and scaffolds are not required, and productivity can be improved and construction cost can be reduced.

Since the work is assembled on the concrete foundation, it is possible to carry out the work on the fine parts with high accuracy, and hence the work quality can be improved.

Since the roof portion is finished first, it is possible to carry out construction without getting the members wet even in the rain.

Planned production is possible, and the construction period can be shortened by about 10 to 20% compared with the general construction method.

Since the unloading device may be a simple multi-stage telescopic type, the equipment cost may be low.
