DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing an exterior wall, such as a mechanical multi-story parking lot, capable of performing exterior work with good workability.

[0002]

2. Description of the Related Art In view of the fact that cities are becoming overcrowded and land shortages are becoming serious, it is no longer possible to construct a flat parking lot in an urban area. For this reason, in recent years, a three-dimensional parking lot has been proposed, and a vertical circulation type parking device, a cage (hanger), in which a large number of cages are circulated up and down in a loop to accommodate a large number of vehicles. Various mechanical three-dimensional parking devices have been developed, such as an elevator-type mechanical parking device in which parking shelves are constructed in multiple stages along the elevating track.

When constructing a parking lot equipped with this type of parking device, an elevator type parking lot will be described as an example. First, pillars are erected at four corners of a site, and a girder material is hung over these pillars. A steel frame structure is constructed, a guide rail and a cage provided along the guide rail so as to be vertically movable;
Parking shelves provided at intervals along the cage elevating trajectory, pallet parking devices for transferring in-vehicle or empty pallets between the cage and the parking shelves, and for entering and leaving vehicles. After constructing a parking device comprising a turntable type pallet swivel installed on the floor directly below the cage, a scaffold is assembled outside the structure, and a wall plate is used by using the scaffold. External wall construction work such as installation was being performed.

[0004]

However, in an overcrowded urban area, it is necessary to construct a parking lot in an extremely limited space, such as between existing buildings, so that wall plates are attached. It is not always easy to assemble a scaffold outside the above structure during repair work after installation. This applies not only to parking lots but also to other buildings.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an outer wall construction method capable of performing construction with good workability from the inside of a structure on which an outer wall is to be formed.

[0006]

In order to achieve the above object, in the method of the present invention, a structure, such as a framework of a mechanical multi-story parking garage, formed by hanging a girder material over a plurality of columns is provided. When forming the outer wall as described above, as a wall plate constituting the outer wall, is divided into a large number in the surrounding direction of the structure,
Using a panel having an engaging portion for engaging the divided parts at the butting portion of each other, attaching a hook to each panel to suspend it by engaging it with the beam member from above,
These panels are hung on a girder to form an outer wall in sequence, and the last two panels are engaged with each other so that their butted portions protrude outward from the structure, and then pulled from the inside of the structure. Then, the engagement is completed.

[0007]

As described above, when constructing a mechanical multi-story parking garage, an outer wall is constructed after a parking device is constructed inside the structure. The present invention pays attention to this point, and constructs an outer wall by using a parking device constructed in a structure as a transport means of a wall plate and a work scaffold.

The above-mentioned panel used as a wall plate has the above-mentioned hook attached to one surface thereof (the surface which becomes inside when it is attached to the structure), and then is placed on a cage of a parking device to park a place where an outer wall is to be formed. Transfer to shelf. An operator also rides on the cage, and the panels are hung from the inside of the structure from the inside of the structure using the parking shelves as a scaffold to form an outer wall sequentially. The last two panels are engaged with each other so that the butted portions protrude outward from the structure, and then pulled from the inside of the structure to complete the engagement. Push the panel to the left and right and install the panel without any gaps. In the case where the outer wall is formed by mounting panels in several steps, the operation of the next step is performed after the panel mounting operation is completed for one step. In this case, the work is performed in order from the lower stage to the upper stage, and the upper panel is mounted so as to slightly overlap the outer side of the lower panel. This is to prevent rain from entering.

When an outer wall is formed on a structure of a building that is not provided with a parking device, such as a frame of a factory building, a scaffold is assembled inside the structure, so that the panel mounting work is performed from the inside of the structure. It can be performed.

[0010]

1 to 4 show an embodiment of the present invention.
This will be described.

The structure (frame) of the mechanical multi-story parking garage is composed of a total of four pillars 1 (FIG. 2) erected at the four corners of the site, and a girder member 2 which extends horizontally adjacent to each other. You. The beam members 2 are attached in multiple stages at predetermined intervals in the up-down direction so as to surround the four columns 1. An elevator type or other mechanical parking device (not shown) is provided inside the structure.
After constructing the outer wall, the outer wall is constructed by using the constructed parking device as a transport means and a work scaffold for the wallboard.

As the wall plate, a panel 4 is used which is divided into a large number in the surrounding direction of the structure and has engaging portions 4a on both left and right side edges for engaging the divided members. This panel 4
Is also divided into a large number (corresponding to the number of steps of the girder 2) in the height direction of the structure, and is formed in a corrugated plate shape to have strength. The engaging portions 4a are formed by bending left and right side edges of the panel 4 into male and female shapes, respectively, and the panels 4 are connected to each other so as to bendable and slidable with each other as the fulcrum. The structure is As shown in FIG. 4, a seal member 7 is attached to the joint surface 6 of each panel 4, and sufficient waterproofness can be obtained by abutting the adjacent members.

When attaching the panel 4 to the above structure,
Hooks 5 are attached to one side of each panel 4 so that they can be engaged with the beam 2 from above and suspended. Then, the panel 4 to which the hooks 5 are attached is placed on the cage of the parking device constructed inside the structure, and the required number of sheets are first conveyed to the first (lowest) parking shelf. An operator also rides on the cage and uses the parking shelves as a scaffold, as shown in FIG.
Is suspended on the beam 2 to form an outer wall in order. Each girder material 2
As shown in FIG. 1, the last two panels 4 are engaged with each other with their butting portions (engaging portions 4) protruding outward from the structure, and then, as shown in FIG. The engagement is completed by pulling them from the inside and dropping them at the same time. Thereby, the panels 4 on both sides of the last two panels 4 are pushed to the left and right, and the panels 4 are attached without any gap. Next, the hook 5 of each panel 4 is screwed and fixed to the beam 2. After the fixing of the panel 4 for one step, as shown in FIG.
The corner wrapping plate 7 is attached to both panels 4 adjacent to each other at the portion to eliminate a gap. Thus, a first-stage outer wall is formed.

After forming the outer wall of the first step, the second step, the third step,...
Then, the upper outer wall is formed sequentially to complete the outer wall surrounding the entire structure. However, in this case, in order to prevent rainwater from entering the structure, it is necessary to mount the upper panel 4 so as to slightly overlap the outer panel 4 on the lower panel 4. The same applies to the corner wrapping plate 7 at each corner.

According to the method of this embodiment, when constructing the outer wall, the parking device constructed in the structure is used for the scaffold without separately assembling the scaffold as in the prior art, and the outer wall can be easily worked from the inside. Construction work can be performed. Therefore, this method is extremely effective as an external wall construction method when constructing a mechanical multi-story parking lot in an extremely limited space where an external scaffold cannot be assembled. Since the work of assembling and removing the scaffold is unnecessary, the construction period of the exterior work can be significantly reduced. In addition, by using a panel 4 having a structure in which an outer wall can be easily formed by hanging from the inside of the structure to the girder member 2 from the inside of the structure, the outer wall can be replaced or repaired after the parking lot is completed. In such a case, these operations can be easily performed using the parking device in the structure as a work platform.

[0016]

In summary, according to the outer wall construction method of the present invention, an outer wall can be formed with good workability from the inside of a structure without using an external scaffold.
