Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a roof of a building on a concrete foundation, pushing up the roof with a jack device, and then assembling a wall frame or an outer wall material into a space between the concrete foundation and the roof. And a house-up device for assembling the same.

[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 house-up device that enables construction with only a carpenter without the need for a decker truck, 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 tension devices for holding the horizontal position of the jack device and the roof part for each, and attach the wire of the wire tension 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 out the wire in a restricted state as the roof rises,
The jack-up device and the collapse prevention device are separate devices and functions, and are shared by a plurality of places so that the individual jack-up device and the collapse prevention device can be downsized to solve the above problems. is there.

Further, in the jack-up device, the divided columns are set on the vertically moving jack table so as to divide the required amount of elevation of the roof part, and the columns are raised, and the divided columns are sequentially set from the bottom. Raise the roof to a specified height.

Further, in a restricted feeding state of the wire due to vertical pushing up of the roof portion, immediately after the wire is fed out, the wire is wound up by a drum and the wire is stretched and deformed within the elastic limit to hold the position of the roof portion. By doing so, the horizontal tensile force is constantly applied to a plurality of portions of the roof portion to prevent the roof portion from collapsing in the horizontal direction.

That is, as shown by the alternate long and short dash line in FIG. 19, when the jack table 12 is rotated by a predetermined angle, FIG.
As shown in FIG. 9, the pedestals 54, 54a... Of the jack table 12 are retracted from immediately below the upper divided support column 61, and as shown in FIGS. 9 (d) and 10 (b). The next divided support column 61a is disposed immediately below the above, and in such a state, there is a margin α between the upper divided support column 61 and the next divided support column 61a.
With the above spacing, the arrangement of the next divided support column 61a is facilitated.

Then, as shown in FIGS. 10 (b) and 10 (c),
The fitting projection 6 at the upper end of the support columns 62, 62a,.
Next, as shown in FIG. 10 (d), the next divided support column 61a is lifted so that 6, 66a... Are fitted into the raised support columns 62, 62a. Then, the jack table 12 is rotated to return to the original position (the solid line position in FIG. 19), and the pedestals 54, 54a,... Of the jack table 12 are positioned immediately below the next divided support column 61a.

Then, the bases 54, 54 of the jack table 12
The lower portion of the divided support column 61a is slightly lowered so that the fitting recesses 64, 64a at the lower end of the next divided support column 61a are fitted into the fitting protrusions 55, 55a of a. Five
4, 54a…, the next divided strut 61a, the raised divided strut 61, 61

Due to the vertical movement of the second, third,.
When the roof A is raised by a necessary amount (total span TSP) as shown in FIG.
The outer wall material E is attached between the projecting foundation C and the roof part A.

In the case of a building D having two or more floors, the house-up work is performed on the outer wall material E installed on the projecting foundation C in substantially the same procedure as the outer wall material E on the first floor.

On the other hand, when the roof part A is lifted by the jack devices 1, 1a, ..., The wire tensioning devices 2, 2a ... Have the following actions to prevent the roof part A being lifted and raised from collapsing in the horizontal direction. To do.

That is, the tips of a large number of wires 105 of the wire tensioning devices 2, 2a ... Installed on the ground GL are fixed to the roof part A, and some of the wire tensioning devices 2, 2a ... 105 is stretched straight and slanted without any slack, and the roof part A rises little by little at a constant speed.
The roof portion A is pulled in a plurality of horizontal directions by the wire 105 wound around the non-rotating drum 104 and in a non-retractable state, and the roof portion A is prevented from collapsing.

Then, as the roof portion A rises, the wire 105 in the unslacked state continues to have a tensile action, so that the wire 105 is stretched and deformed within its elastic limit, that is, extended, and the roof portion is extended. The tensile action on A is continued.

In the tensile deformation state of the wire 105 within the elastic limit, a plurality of wire tensioning devices 2, 2a
Are sequentially operated, that is, the motors 101 of the wire tensioning devices 2, 2a are rotated in the forward and reverse directions to eliminate the tensile deformation state of the wire 105 and reset the state without slack.

More specifically, the motor 101 is rotated in the forward direction to extend a predetermined amount (expected deformation extension amount + α) of the wire 105 to change the wire 105 from a tension state to a relaxation state, and the wire 105 is instantly deformed by pulling. Immediately after eliminating the condition,
The motor 101 is rotated in the reverse direction to apply tension, and the wire 105 is wound up. State.

Then, the wire 105 is formed in a straight line,
When it becomes impossible to wind up, the motor 101 stops rotating when the transmission force of the torque limiter 107 is exceeded and the motor 101 idles, and the wire 105 is in a state without slack and decelerates. The machine 102 has a reverse rotation preventing action having a worm and a worm wheel to set a state in which the wire 105 can be pulled and deformed within the elastic limit.

As an example of the feeding setting time of the wire 105, any time may be set as long as it is within the elastic limit of the wire 105. For example, by predicting the time when the deformation elongation rate of the wire 105 approaches 3%, Set the tension state by loosening the wire 105 so as to feed out% (3% + α).

Further, as shown in FIGS. 8B and 8C, when the jack table 12 for the fixed stroke KS is temporarily lowered, the tensile deformation state of the wire 105 is reduced but the tension state is maintained. By setting the tension state, the roof portion A is prevented from collapsing even at this time.

The stopper arms 86, 86a are returned by lowering 61, 61a, and the upper divided support column at the time of the lowermost of the divided support columns 61, 61a.
61, 61a ... are held.

Then, the jack table 12 and the upper divided columns 61, 61a are arranged in the reverse order of the connection of the divided columns 61, 61a.
Are lifted, the jack table 12 is rotated, the lower divided posts 61, 61a,... Are removed, and then the lower divided posts 61, 61a,.

In order to lift the roof part A when the divided columns 61, 61a are raised, three stoppers 83, 83a are used, but when the divided columns 61, 61a are lowered, the divided columns 61, 61a. 61a ... Because of its own weight, one stopper
83, 83a ... alone can withstand the load.

Further, in the wire tensioning devices 2, 2a ..., The wire 105 is wound up by the operation of the motor 101, and in the height detecting devices 3, 3a ..., The winding adjusting member 127 is used as the sensor wire. After fixing 122, the sensor wire
Remove the tip of 122 and put all sensor wires on the ground.
After dropping the sensor wire 122, the sensor wire 122 is regularly wound around the drum 123 while adjusting the winding adjusting member 127.

Incidentally, although the raising amount setting in the jack devices 1, 1a ... Is divided, the present invention is not limited to this type, and it is also possible to raise the entire raising amount at a time, and the feed screw 27 Although the jack table 12 is lifted by the feed nut 49 and the feed nut 49, these changes can of course be made, and a pantograph type or other forms may be used.

Further, in the wire tensioning devices 2, 2a, ..., the deformation and extension action of the wire 105 within the elastic limit is utilized, but other methods may be used.
A method in which the drum is instantaneously opened and gripped, and a braking force is constantly applied to the drum so that the drum temporarily rotates when the rotational force exceeds a predetermined torque transmitted from the wire 105. Alternatively, the drum may be freely rotatable by a predetermined amount at a predetermined rotational force or more, or may be of another type.

That is, if the load and strain on the wire 105 are within the elastic limit and the wire 105 extends in direct proportion,
Alternatively, it is sufficient that the wire 105 is not slackened by unwinding the wire 105 according to the load amount. Also, as in the case of setting the tension state in the embodiment, a part of the wire 105 is temporarily relaxed. Is also good.
