Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention is a method for stacking and constructing wall members, which are permanent walls, using mechanical force such as a robot in a construction work space directly above a wall structure to be constructed. The present invention relates to a wall structure construction device that constructs the wall structure by repeating operations.

《Prior art》 In general, construction of high-rise wall structures such as large oil tanks requires
For example, as disclosed in Japanese Patent Publication No. 53-38522, a support tower for supporting a work floor, etc. is installed at the center of the wall structure to be constructed, and a crane is placed on the top of the support tower. This is done by using a crane to pull up wall members, etc., and stack them one by one from the lower layer to the upper layer.

<<Problem to be solved by the invention>> However, with the technology disclosed in the above publication,
Construction involves lifting materials such as wall members with a crane, which requires skilled workers and a large number of hands.Furthermore, since the work is done outdoors at a height, it is affected by the weather and has short working hours. The restrictions were large, often resulting in an extension of the construction period, and great consideration had to be given to the safety of workers.

The present invention has been made in view of the above background, and provides a wall structure construction device that can be preferably applied to unmanned construction of high-rise wall structures using mechanical force, and can improve productivity. Its purpose is to spread the word.

<Means for Solving the Problems> The present invention provides a temporary framework that is disposed above a wall structure to be constructed and forms a construction work space between it and the wall structure below, and A group of extensible columns that are extended downward from this to form temporary columns and form a construction work space between them and the wall structure, and are contracted to form a space for mounting the permanent wall between them and the wall structure. The present invention is characterized by comprising a wall installation means provided on the framework and for mounting the main wall in the mounting space.

Additionally, a temporary cover may be provided on the framework to cover the construction work space.

<Operation> According to the above-described device, the framework is raised by simultaneously extending the plurality of telescopic columns installed in the temporary framework, and a construction work space is created between it and the wall structure under construction. The telescopic column will function as a temporary column for the construction work space. Then, by contracting one of these telescopic columns, a space for installing the permanent wall is created between the framework and the wall structure.

Then, by attaching the permanent wall to the open space using a wall installation means and repeating the installation process according to the contraction movement of the telescopic column, the permanent wall will be completely located below the temporary framework. It can be fitted around the circumference to build up the height section of the wall structure. Then, the telescopic pillars were extended all at once again, and the construction work proceeded further upwards.

In other words, by reversing the expansion and contraction of the expansion and contraction columns, the work can proceed upwards in sequence while securing the construction work space.
It is easy to introduce construction automation and is suitable for automating construction work in combination with other automatic work equipment.

Furthermore, since the construction work space can be shielded from the outside by a temporary cover provided on the framework, the inconvenience of being affected by the weather is eliminated, and construction work can be carried out without disturbing the surrounding environment.

<<Example>> Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view illustrating a preferred embodiment of the present invention using a simplified model.

The present invention basically consists of a temporary framework 3 that is disposed above a wall structure 10 to be constructed and a construction work space 14 is formed between it and the wall structure 10 below; It is extended downward from this to form a temporary column and forms a construction work space 14 between it and the wall structure 10, and is contracted to form a mounting space 15 for the permanent wall 6 between it and the wall structure 10. The wall installation means 9 is provided in the framework 3 and attaches the main wall 6 to the attachment space 15. In addition, a temporary cover 16 covering the construction work space 14 is attached to the framework 3.
may be provided.

The telescopic column 1 is a hydraulic cylinder that extends (extracts) or shortens (retracts) a rod 2 with a stroke slightly longer than the height of one floor of the wall structure 10 using hydraulic pressure. The plurality (here, four) of the telescopic columns 1 are attached to a temporary framework 3 constructed in a predetermined shape (here, rectangular) so as to support this.

Further, here, a mobile crane 5 is arranged between opposing beams 3a and 3b of the framework 3, and a working robot 4 is detachably installed on this mobile crane 5.

In the present invention configured as described above, first, FIG.
), for all the telescoping columns 1, the rods 2 are simultaneously extended from the cylinders by the entire length of the cylinders. As a result, a construction work space 14 is formed between the framework 3 and the wall structure 10, and the rods 2 function as temporary columns. Next, in some of the telescopic columns 1, the rods 2 are housed in the cylinders by the entire length thereof, as shown in FIG. 1(B).

At this time, the framework 3 will be supported by the remaining three rods 2, but at the actual machine level, a far greater number of telescopic columns 1 than four are used and supported by a large number of rods 2, so There is no problem even if a small number of Rods 2 are no longer supported.

A mounting space 15 for the permanent wall 6 is formed directly below the telescopic column 1 where the rod 2 is housed in the cylinder, and the permanent wall 6 is installed in this area as shown in FIG. 1(B). It is installed by a gripping robot 9, which is a wall installation means. In addition, prior to this installation work, since the working robot 4 shown in FIG. 1(A) is a welding robot to be described later,
It is removed from the mobile crane 5 and replaced with the above-mentioned grasping robot 9. Further, the main wall 6 is provided with a plurality of reinforcing ribs 60 on its inner side.

As shown in FIG. 1(C), this permanent wall 6 is held down at its upper end by slightly extending the rod 2 housed in the cylinder, and is firmly fixed onto the wall structure 10 by welding or the like. Ru.

After this, the rods 2 of the other telescoping columns 1 are housed in their entire length in the cylinders, and the mounting slots formed thereby (
Install the main wall 6 on the ground 15 in the same manner as above,
Fix it.

FIG. 1(E) shows the situation when the installation work of the permanent wall 6 described above has been completed around the entire circumference of the wall structure 10. The welding work for the main wall 6 is performed by a welding robot 4 mounted on a mobile crane 5. Thereafter, although not shown in the drawings, various interior work is carried out on the floor.

Next, as shown in FIG. 1(F), the rods 2 are extended from all the cylinders of the telescopic column 1 at the same time, and construction begins on the floor immediately above. In other words, this construction is as shown in Figure 1 (
This is done by repeating operations A) to (E).

Then, by repeating the construction, the construction of the wall structure 10 is progressed one floor at a time from the lower layer to the upper layer, and after repeating for the required number of floors, the framework 3 and the telescopic columns 1, etc. are dismantled and removed, and the The construction of the wall structure 10 is completed by performing various works necessary for the floor portion.

FIG. 2 is a schematic perspective view showing the application of the present invention on an actual machine level, and the same functional parts as those in FIG. 1 are given the same reference numerals.

This figure shows the case where a wall structure 10 with a donut-shaped planar cross section is constructed unmanned, and the inner space is used as an elevator shaft 30 to transport the main wall 6 and other various components. For this purpose, an elevator 31 having a substantially semicircular shape is raised and lowered.

The temporary framework 3 is assembled to have substantially the same cross-sectional shape as the wall structure 10, and a control room (not shown) is installed on the framework 3.

In addition, in constructing the cylindrical wall structure 10, the control of the work robot etc. is based on an easily controllable cylindrical coordinate system or polar coordinate system, so it is easy to control with high precision. , construction costs can be reduced. and,
Various work robots such as the welding robot 4 and the gripping robot 9 are controlled automatically by a worker operating a computer or the like in the control room, as shown in Figs. 1 (A) to (F). This type of work is carried out.

That is, the permanent wall 6 transported from the ground by the elevator 31 is moved by the gripping robot 9 moving on the mobile crane 5 to the telescopic column 1 with the rod 2 housed in the cylinder.
The welding robot 4 welds and fixes it to the upper end of the permanent wall 6 on the lower floor. In addition, the permanent wall 6
are layered inside and out to form a double structure.

Further, the elevator 31 has a floor portion that is rotatable through 360°, and is freely rotated in the direction of a desired mounting position of the main wall 6.

Once the fixing work of the main wall 6 has been completed as described above, various interior work on the floor concerned is carried out by a work robot that can be freely moved on the mobile crane 5, and all the reinforcement columns are fixed again. The rods 2 are extended all at once from the cylinder 1, and the same operation as described above is repeated to construct the floor immediately above.

After the construction of the required floors is completed, the framework 3, telescopic columns 1, etc. are removed and the roof portion is constructed.

In addition, at the actual machine level mentioned above, measures were taken to ensure that various noises on the construction floor do not leak into the surrounding area, and that electrical signals from the control room computer to the work robots and other equipment are not affected by surrounding radio waves and electromagnetic waves. Furthermore, a temporary cover 16 for soundproofing, electromagnetic shielding, and wind and rain shielding is attached to the framework 3 to prevent wind and rain from entering the control room and construction floor. This temporary cover 16 is composed of a temporary roof 38 and an enclosure 39.

In this way, by providing the temporary cover 16 to provide a soundproofing function and an electromagnetic shielding function, it is possible to maintain a favorable construction work environment and prevent computers and working robots from running out of control. Moreover, if the temporary roof 38 is constructed from the roof member of the wall structure 10, this can be used as the roof part of the wall structure 10 as it is.

<<Effects of the Invention>> According to the present invention described in detail above, the following effects can be achieved.
