Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, assembling a roof of a building on a concrete foundation, pushing up the roof with a jack device, and then installing a wall axle or an outer wall in a space between the concrete foundation and the roof. The present invention relates to a horizontal measuring device for a building ascending method, which is used in a construction method for assembling materials and the like, and detects a horizontal state of an elevated roof portion.

[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.

Further, when the roof is jacked up, if the roof is pushed up in a completely horizontal state, a lateral displacement of the roof occurs, and the outer wall material cannot be vertically assembled between the floor dyeing and the shed dyeing. If the accuracy and strength of the jack-up device must be significantly increased, or if a fall prevention device is used, a delicate adjustment work is required, and the work has a completely different purpose and characteristics from the original purpose of the fall prevention. And it was impossible to provide commonality.

Further, the jack-up device and the fall prevention device are large in size and have a drawback that the removal operation is very difficult because they are present inside the building after the completion of the building.

[0011]

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 realized, making it possible to build with only a carpenter without the need for a decker truck, and also safely and accurately maintain the level of the pushed up roof when constructing the building It is an object of the present invention to provide a horizontal measuring device for a building ascending method in which a state is detected and the building is rebuilt by utilizing a collapse prevention effect which has been shared.

[0012]

SUMMARY OF THE INVENTION According to the present invention, a jack-up device and a fall prevention device based on the above-mentioned prior art are large devices, which still require a decker truck, and that the pushed-up roof is non-horizontal. In consideration of the problem that requires rebuilding when in the state, a jack device for pushing up the roof on the ground etc., a wire tensioning device for maintaining the horizontal position of the roof, and a horizontal measuring device for detecting the horizontal state of the roof, respectively Install multiple.

[0013] The wire of the wire tensioning device is attached to the roof in a state where the wire is not loosened, the roof is pushed up by the jack device, and the wire is fed out as the roof rises. The separate jack-up device and the collapse prevention device are miniaturized by performing the up and collapse prevention by separate devices and functions, and by sharing them at a plurality of locations.

Further, even if the roof is pulled in the horizontal direction by the wire tensioning device, even if the maintenance of the horizontal direction is broken even by a small amount, the non-horizontal state of the roof is detected by the horizontal measuring device, and the jack-up is stopped. In order to solve the above problem, some of the wire tensioning devices were used to pay out and store the wire, pull the roof in the required direction, restore the horizontal state of the roof, and rebuild the roof. Things.

Further, the horizontal measuring device senses by detecting the contact between the vertical reference wire and the detection plate, and as a concrete means, attaches the upper end of the reference wire to the roof portion, and mounts the upper end of the reference wire on the concrete foundation (post of the board). In addition, a detection plate is set up, and a reference wire is fed out and stored in accordance with the vertical movement of the roof, and the detection of contact between the reference wire and the detection plate is converted into an electric signal to utilize a wire tensioning device in a fall prevention device.

That is, the tips of a large number of wires 105 of the wire tensioning devices 4, 4a,... Installed on the ground GL are fixed to the roof A, and a part of the wire tensioning devices 4, 4a except for those momentarily in a tension state is set. As shown in FIG. 23 (a), the wire 105 is stretched in a straight line or a slanted shape without slack, and the roof A is gradually raised at a constant speed little by little, wound around the non-rotating drum 104 and fed out. Disabled state and tension applying part
Roof A is pulled in a plurality of horizontal directions by wires 105 tensioned at 103, and roof A is prevented from collapsing.

Then, as shown in FIG. 23 (b), as the roof A rises, the tension acts continuously on the wire 105 in a state where there is no slack, so that the middle part of the wire 105 becomes a tension applying part. The roller 106 is bent by the roller 106 at 103, and is pulled by the spring 115.

By operating the devices 4, 4a, etc., the lateral displacement is corrected and corrected (rebuilding), the ascent is restarted, or the outer wall material E is installed.

When the height detectors 3, 3a,... Or the second height detector 6 are operated, for example, if the roof A is not evenly raised for some reason, the height is detected. , Or the encoder 136 of the second height detecting device 6 detects an abnormal rise, and the jack devices 1, 1a, and the wire tensioning devices 4, 4a,. The operation is urged or the operation of other things is temporarily stopped, and the roof A is evenly raised.

Next, after the roof A has been completely lifted, the outer wall material E is constructed, and the jack devices 1, 1a,..., The collapse prevention devices 2, 2a,. Of the wire tensioning devices 4, 4a,..., The horizontal measuring devices 5, 5a and the height detecting devices 3, 3a,.

For the jack devices 1, 1a,.

The lower divided support columns 61, 61a,... Arranged between the... Are removed, and then the lower support columns 61, 61a are sequentially lowered in the above procedure.

When the divided columns 61, 61a are raised, the two stoppers 83, 83a are used to lift the roof A, but when the divided columns 61, 61a are lowered, the divided columns 61, 61a,. 61a… only one weight, one stopper
83, 83a ... alone can withstand the load.

In the wire tensioning devices 4, 4a,... Of the fall prevention devices 2, 2a, the wire 105 is wound by the operation of the motor 107. In the horizontal measuring devices 5, 5a,
The adjustment wire 160 and the reference setting wire 161 are wound by rotating the winch operating rod 166c, and the height detecting device 3,
For 3a…, take-up adjustment member 127 uses sensor wire
After fixing the sensor wire 122, the tip of the sensor wire 122 is removed, and all the sensor wires 122 are dropped on the ground. Then, the sensor wire 122 is neatly wound around the drum 123 while adjusting the winding adjusting member 127.

In addition to the above embodiment, a description will be given of a modification of the construction method in the building ascending method. First, in the jack devices 1, 1a,... However, it may be an operation source other than the electrically operated type, for example, a hydraulic type, a pneumatic type, a cylinder type, or the like.By making the type electrically operated, in a normal construction site, since a power source exists, There is an advantage that installation and operation of the jack devices 1, 1a,... Can be facilitated.

Although the setting of the amount of rise in the jack devices 1, 1a,... Is divided, the type is not limited to such a type. Although the jack table 12 is raised by the feed nut 49 and the feed nut 49, these changes can of course be made, and a pantograph type or another type may be used.
