Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a width-shifting device that can be applied to work for laying an exterior panel on a structural member.

[Prior art]

In recent years, the housing industry has developed, and along with it, the advantages of lightweight, heat insulation, fire resistance, etc. have been utilized, and lightweight cellular concrete panels (hereinafter referred to as ALC panels) are widely used as building materials for exterior panels. In the exterior work of ALC panels, the ALC panel is attached using washers and bolts that penetrate through holes in the thickness direction, and it is also attached using a metal plate, but this is troublesome. In addition to the high cost, there is a drawback that the appearance is impaired when the panel is laid and there is a problem with the external coating. In order to improve this drawback, in the ALC panel manufacturing process, an ALC panel in which reinforcing bars are arranged and locking fittings are embedded in advance is manufactured. When assembling the ALC panel, attach the ALC panel to the structural members using the screw holes (screw holes) of the locking metal fittings. That is, the locking metal fittings are also attached to the structural member, the bolts are screwed into the screw holes, the exterior panel of a predetermined shape is fixed to the structural member, and further, the ALC panel is attached,
The most common method is to inject a seal into the joint and smooth the surface with a spatula. For that purpose, external scaffolding and a portable fishing basket device (gondola) are used. The space between adjacent buildings is narrow when the joint seal is installed on site,
In many cases, there are obstacles that make construction difficult, and the amount of investment in incidental construction and scaffolding will increase accordingly. As a method for remedying this drawback, the open joint construction method or the seal construction method, which can be used without scaffolding, is also popular. In this case, at the time of assembling the ALC panel, the seal packing of the joint is placed on the side surface of the ALC panel in advance, and the ALC panels to which the seal packing has been adhered are sequentially attached. Therefore, it is necessary to perform a seal packing compression work to prevent the intrusion of water from the joint portion. However, at the construction site, it is not easy to sufficiently join and compress the seal packing provided in the joints of the long panels,
It had the drawback that the ALC panel assembly work did not proceed as expected. Therefore, in order to solve these drawbacks, a width aligning device that can be used even in a narrow space is expected.

[Problems to be Solved by the Invention]

As shown in FIG. 6, when assembling the exterior panel,
The locking metal fitting 18 is embedded in the ALC panel 12 in advance, the hook bolt 20 is screwed into the screwing hole of the locking metal fitting 18, and the ALC panel 1 is lifted by operating the crane or the lifting device (not shown).
2 is loaded onto the structural member 10. Place the packing material of the jointing material on the side surface 14 of the ALC panel 12 and attach it with the support metal
The panel 12 is joined to the structural member 10. At this time, press the side of the ALC panel 12 with the lever as a fulcrum for input, compress the seal packing while moving the ALC panel 12, or, as shown in the figure, the width at which the support metal fitting 32 is joined to the screw tip of the tamper pack. Using the aligner 30, ALC
The support fitting 32 is inserted into the blind hole 12a of the panel 12. (In the figure, the width-shifting fitting 30 is shown in a state before the support fitting 32 is inserted.) Then, the handle 36 is inserted into the groove (opening portion) of the support rod 34, and the support rod 34 is rotated. The ALC panel 12 is attached while being pulled by using screws. However, when operating the handle 36, at the construction site the handle
36 may come in contact with obstacles and handle operation may be difficult,
It takes a long time to set the ALC panel 12, and if the ALC panel 12 is moved forcibly, there are drawbacks such as damage to the ALC panel 12 and damage to its appearance.

[Means for Solving the Problems]

An object of the present invention, as a method for solving these problems, is to provide a width-shifting device in which the operating range of the handle is reduced. The width-adjusting device of the present invention is used to attach exterior panels such as an ALC panel sequentially and adjacently in the width direction,
A gear device housed in a housing, a pair of bearing rods fixed to the housing, extending in mutually opposite directions and having axial slots, and extending in the bearing rod in the axial direction, respectively. A pair of screw shafts which are connected to the bearing rods and are rotatable with respect to the bearing rods; And a drive device connected to a gear device for rotating the screw shaft. Further, the drive device is provided with a clutch device so that the pair of screw shafts can be rotated simultaneously or only on one side, and can be reversed.

[Action]

As a means for moving the ALC panel, a locking metal fitting for an anchor member is embedded in advance on the rear surface of the exterior (wooden) surface of the ALC panel to provide a screw hole, but in the present invention, a blind hole for width adjustment is further provided. Set up. Insert two floating support metal fittings into the blind holes for the two ALC panels (one is the fixed ALC panel that has already been installed and the other is the width-shifting ALC panel to be installed). The screw shaft incorporated in the width-shifting device is rotated by a drive device (for example, a wrench) via the gear device via the gear device. At this time, by rotating or operating the clutch device such as the switching lever or the ratchet to the left or right, the compression width close adjustment can be finely adjusted without damaging the appearance of the panel. In adjoining buildings or narrow construction sites, it is also important that the width-shifting device is lightweight and can change its direction freely, so that the width-shifting packing of panels can be compressed more quickly than in the past.

【Example】

First, the outline of the attachment of the ALC panel will be explained. As shown in FIG. 1, a locking metal fitting 18 is embedded in advance in the small surface 16 of the ALC panel (exterior panel) 12 having a predetermined length. The hook bolt 20 is screwed into the screwing hole of the locking metal fitting 18, and a crane or a hoisting device (not shown) is used, and the structural member 10 is lifted.
Bring it on. On the structural member 10, the first ALC panel 12 (the one on the right side in the drawing) is fixed to the stopper 10a that serves as a guide. This work sets the reference position of the ALC panel 12. Next, the ALC panels 12 to be sequentially attached are attached according to the reference position. That is, as described above, the ALC panel 12 (the one on the right side in the drawing) is fixed, and the ALC is
While suspending the panel 12 (the one in the center in the drawing), the ALC panel 12 on the right side in the drawing is the fixed side, and the ALC panel on the fixed side
Adjacent to the seal packing of 12 so that the joint groove of the ALC panel 12 on the width side (center in the drawing) is in contact. Next, a width-shifting device is applied in a state in which the ALC panel 12 is fixed by bolts (not shown) so as not to fall down in alignment with the screw holes of the locking metal fittings 18. The configuration of the width aligning device 30 will be described in detail later. When applying the width-shifting device 30, inserting the support pins 62 of the width-shifting device 30 into the blind holes 12a on the back surface of the ALC panel 12, respectively, while operating the ratchet wrench 52 to move the width-shifting side ALC panel 12, The seal packing is compressed so that the width-shifting side ALC panel 12 is brought into close contact with the fixed side ALC panel 12. Further, a new ALC panel 12 (the one on the left side in the drawing) is similarly attached with the central ALC panel 12 as the fixed side in the drawing. As shown in FIGS. 2 and 3, the width-shifting device 30 includes a gear device (a combination of three bevel gears 56 and 58 in this embodiment) housed in a housing or a support frame 40, A pair of bearing rods 42 rotatably fixed to the housing or the support frame 40, extending in mutually opposite directions and having axial grooves, and extending in the bearing rods 42 in the axial direction, respectively. A pair of screw shafts 46 that are connected to the bevel gears 56 and are rotatable with respect to the bearing rods 42.

Although it is rotatably fixed with respect to, it may be simply fixed. The driving device is provided with a clutch device (in the case of the present embodiment, a ratchet 54 or the like) so that the pair of screw shafts 46 can be rotated simultaneously or only on one side, and can be reversed. The housing or support frame 40 may be a closed type, but both sides may be open like a simple frame, or one side like a box may be open. However, in order to reduce the weight, the open shape is preferable. As shown in the drawing, the pair of bearing rods 42 symmetrically extend in opposite directions from the bevel gear 56 housed in the housing or the support frame 40, and the axial center portion is hollowed to form a slot. . The screw shaft 46 penetrates the bearing 44 of the bearing rod 42, enters the housing or the support frame 40, and is connected to the bevel gear 56. A drive shaft 48 is inserted into the housing or the support frame 40 through the bearing 46, and is connected to the bevel gear 58 via a slidable thrust ring 50. A ratchet wrench 52 is fitted on the opposite end of the drive shaft 48. The ratchet wrench 52 is provided with a ratchet 54 for switching operation. The input from the ratchet wrench 52 enters the screw shaft 46 via the drive shaft 48 and gears 56, 58,

The floating support fittings 60 approach each other like dragging. Further, the support pin 62 can be rotated along the circumference of the floating metal fitting 60, and when it is difficult to operate the handle of the ratchet 54 due to contact with an obstacle, it is possible to change the direction of the support pin 62 and operate it. . An embodiment in such a case is shown in FIG. Fig. 5 shows the blind perforations 1 on the back side of the ALC panel 12 in Fig. 1.
While the support pin 62 of the width-shifting device 30 is inserted into 2a, the support pin 62 of the width-shifting device 30 is inserted into the blind perforation 12a on the forefront surface of the ALC panel 12. Width adjustment device

【The invention's effect】

INDUSTRIAL APPLICABILITY Since the present invention is configured as described above, it is suitable for a work space with a small space such as an ALC panel installation work of a relatively adjacent building, for example, a hole drilled on the back side of an already installed ALC panel. When this width aligning device is applied, the seal packing can be compressed without damaging the exterior surface. Moreover, this width-shifting device is lightweight and easy to switch,
Since the operating range of the handle that moves the ALC panel to the left and right is small, the construction period for installing the ALC panel and the construction cost are reduced, which is very effective. Although the present invention has been described with respect to ALC panels, it goes without saying that the present invention can be applied to panel-like structures used in similar fashion.
