Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of assembling a roof of a building on a concrete foundation, pushing up the roof with a jack device, and then installing a wall frame, an outer wall material, etc. in a space between the concrete foundation and the roof. It is related to the construction method of assembling.

[0002]

2. Description of the Related Art Conventionally, as a construction method of a steel structure house, a wooden house, a PC concrete house, a prefabricated house, and the like,
When assembling the floor material on the first floor, the outer wall material, the floor material on the second floor, the outer wall material, the ceiling, the roof, etc., sequentially from below on the constructed concrete foundation, use building materials with a decker truck (truck crane). The construction method of assembling a building on a concrete foundation while lifting a building was performed.

However, the above-mentioned construction method using a decker truck cannot be performed in a densely populated area or in a place where the approach road is narrow. That is, the decker truck cannot be used on the side of the truck for stable work with respect to the width of the road adjacent to the building site. The outrigger provided on the side protrudes sideways and lands on the ground, occupying the road and causing a traffic obstacle, or when building at the back of a narrow living road, a decker car can be inserted into the living road Therefore, the above construction method using a decker truck could not be adopted.

[0004] Decker cars are generally rented, and the permanent location and the construction site are usually separated from each other. One day's use of the decker vehicle is a reciprocating movement between the permanent location and the construction site. It is necessary other than when using the car, and the rental fee can not use the expensive decker efficiently, causing cost increase, and the carpenter who is the operator of the decker car and the construction worker are separate Therefore, there was a disadvantage that the schedule between the operator and the carpenter had to be adjusted.

[0005] In addition, when building sequentially from the top of the concrete foundation, the construction work place is gradually elevated,
It was dangerous, and construction work at high places was disliked, leading to a shortage of manpower, and the work could not be performed in rainy weather.

[0006] Therefore, a method of assembling from the roof of a building on a concrete foundation, and sequentially jacking up with a building jack device from the finished portion has been adopted in some parts.

[0007] However, such a jack-up method also has a weak point. For example, in a construction site where a decker vehicle cannot enter because of the large size and considerable weight of a building jack device, a decker vehicle is required. It was impossible to install a jack-up device for construction.

In addition, when jacking up a roof or the like,
Since only the jack-up device is interposed between the concrete foundation and floor beam or hut beam, there is a risk that the building will collapse during strong winds or other accidents,
The anti-collapse device installed for this purpose is also a large device like a jack-up device, or a jack-up device that also has a collapsing prevention function is a very large and heavy device, and the jack-up method is not fully adopted. It has not yet arrived.

Also, the jack-up device and the collapse prevention device are disadvantageous in that they are large in size and are very difficult to remove because they are present inside the building after the completion of the building.

[0010]

SUMMARY OF THE INVENTION According to the present invention, the use of a jack-up device and a fall prevention device, and the sharing, miniaturization, and division of the operation of these devices make it possible to assemble the roof in advance.
The construction method of assembling the outer wall material after pushing up is to provide a construction method that enables construction with only a carpenter without the need for a decker car, and that enables safe construction of the building. It is.

[0011]

According to the present invention, the jack-up device and the collapse prevention device based on the above-mentioned prior art are large devices, and in view of the problem that a decker vehicle is still required, the roof portion is pushed up on the ground or the like. Install a plurality of wire tensioning devices for holding the horizontal position of the jack device and roof part for each, install the wire of the wire tensioning device to the roof part in a state where the wire is not loose, and push up the roof part with the jack device, By letting the wire pay out as the roof rises, jack-up and collapse prevention are performed by separate devices and functions, and by sharing at multiple places, individual jack-up devices and collapse prevention devices. The above problem is solved by downsizing.

In addition, in a state where the wire is fed out when the roof portion is pushed up in the vertical direction, the middle portion of the wire is hung on the roller, the wire is bent through the roller in the direction orthogonal to its axis, and the roller is spring-loaded. By applying an urging force, horizontal tension at multiple points of the roof part is constantly applied by the movement of the position of the roller, the change of the bent state of the wire, and the wire feeding action from the drum. To prevent the roof from collapsing horizontally.
