Abstract

PURPOSE:To make external panel fitting works more efficient by firmly fixing bevel gears to one ends of a pair of spiral shafts provided with loose fittings for moving panels in their width direction having pins to be engaged with panels and coupling the bevel gears with each other by means of a bevel gear which is rotated by a ratchet wrench. CONSTITUTION:Bevel gears 56 are firmly fixed to one ends of a pair of spiral shafts 46 provided with loose fittings 62 which are used for moving external panels in their width direction engaged with holes 12a provided on the surface of external panels 12. The gears 56 are housed in a housing and, at the same time, coupled with each other by means of a bevel gear which is rotated by a ratchet wrench 52. When the shafts 46 are turned and the fittings 62 are slid by swinging the wrench 52, the panels 12 are moved in their width direction. In addition, clutch devices are installed so as to make the shafts 46 rotatable in one direction only or in the opposite direction also. Therefore, the panels 12 can be moved in their width direction efficiently.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a width adjustment device that can be applied to construction work in which exterior panels are installed on structural members.

[Conventional technology]

With the development of the housing industry in recent years, lightweight aerated concrete panels (hereinafter referred to as ALC panels) have been widely used as building materials for exterior panels, taking advantage of their advantages such as light weight and fire resistance. In the exterior work of ALC panels, methods are used to attach the ALC panels, such as using washers and bolts with holes drilled through the thickness, or attaching via metal plates, but these methods are time-consuming and time-consuming. However, in addition to high costs, there are drawbacks such as spoiling the appearance and problems with external coating when installing the panels. In order to improve this drawback, in the manufacturing process of ALC panels, reinforcing bars are placed and locking metal fittings are embedded in advance.
panels are manufactured. When assembling the ALC panel, the ALC panel is attached to the structural member using the screw holes of the locking fittings. In other words, a locking metal fitting is also attached to the structural member, a bolt is inserted into the threaded hole, an exterior panel of a predetermined shape is fixed to the structural member, and after the ALC panel is attached, a seal is injected into the joint. The most common method is to use a spatula to smooth the surface. for that purpose,
External scaffolding and portable fishing r! Equipment F (gondola) etc. are used. When installing joint seal ring 4, the distance between adjacent buildings was too small.
There are many cases in which it is difficult to construct a bridge due to obstacles, and the amount of investment required for incidental construction work, scaffolding, etc. is also large. As a method to improve this drawback, open joint construction methods or seal construction methods, which can be constructed without scaffolding, are also becoming popular. In this case, when assembling the ALC panel, the seal backing at the joint portion is adhered to the side surface of the ALC panel in advance, and the ALC panels to which the seal backing has been adhered are sequentially attached. Therefore, seal backing compression work is required to prevent water from entering through the joints. However, at a construction site, it is not easy to sufficiently bond and compress the seal backing provided at the joints of long panels, and this method has the disadvantage that the assembly of ALC panels does not proceed as expected. Therefore, in order to eliminate these drawbacks, there is a need for a width adjustment device that can be used even in narrow spaces.

However, when operating the handle 36, the handle 36 may come in contact with an obstacle at a construction site, making it difficult to operate the handle, and it takes a long time to set the ALC panel 12, and if it is forcibly moved, the ALC
There were drawbacks such as damage to the panel 12 and deterioration of its appearance.

[Means for Solving the Problems] As a method for solving these problems, it is an object of the present invention to provide a width shifting device in which the operating range of the handle is reduced. The width adjustment device of the present invention is used to attach exterior panels such as ALC panels adjacent to each other in the width direction, and includes a gear device housed in a housing and a gear device each fixed to the housing and opposite to each other. A pair of bearings each extending in a direction and having an axial slot are connected to a rod, the bearings each extending in an axial direction through the rod, and a pair of screws connected to the gearing so that the bearings are rotatable relative to the rod. a shaft, and a floating support fitting for width adjustment protruding from a slot in the rod so as to be slidably engaged with the screw shaft, and to engage with the exterior panel; It consists of a drive device connected to a gear system. Furthermore, the drive device is provided with a clutch device to rotate the pair of screw shafts simultaneously or only on one side, and to rotate them in reverse. [Operation Go] As a means of moving the ALC panel, a locking fitting for an anchor member may be buried in advance on the back side of the exterior (wooden) surface of the ALC panel to provide a screw hole, or in the present invention, a screw hole may be provided for the anchor member. Make a blind hole. Two ALC panels (one is installed fixed side A L)
Try installing the other one on the C panel. Fukuyose measurement ALC
(panel), insert the floating support fittings for width adjustment into these blind holes. A screw shaft built into the width adjusting device is rotated by a drive device (for example, a wrench) via a gear device. At this time, by rotating or operating clutch devices such as switching levers and ratchets to the left and right, you can do this without damaging the appearance of the panel.
You can finely adjust the compression width of the seal backing. For adjacent buildings or narrow construction sites, it is important that the width adjustment device is lightweight and can change direction freely, allowing the panel width adjustment backing to be compressed more quickly than with conventional methods. [Example] First, an outline of the installation of the ALC panel will be explained. As shown in FIG. 1, the hook bolt 20 is screwed into the threaded hole of the locking metal fitting 18, which is embedded in the edge surface 16 of the ALC panel (exterior panel) 12 of a predetermined length in advance.
The lift is loaded onto the structural member 10 using a crane or lifting equipment (not shown). On the structural member 10, the first ALC panel 12 (the one on the right in the drawing) is fixed to a stopper 10a that serves as a guide reference. This operation sets the reference position of the ALC panel 12. Next, the ALC panels 12 are sequentially attached according to the reference positions. In other words, by fixing the ALC panel 12 (the one on the right in the drawing) as described above, while suspending the ALC panel 12 (the one in the center in the drawing) using a crane, etc., fix the ALC panel on the right in the drawing. 12 on the fixed side, align the width fl with the seal backing of the ALC panel 12 on the fixed side.
The joints of the llALc panel 12 (center one in the drawing) are placed adjacent to each other so as to be in contact with each other. Next, the width adjustment device is applied while being fixed with bolts (not shown) to the extent that the ALC panel 12 is not scraped in alignment with the screw hole of the locking fitting 18. The configuration of the width adjustment device 30 will be explained in detail later. When applying the width shifting device 30, insert the support pins 62 of the width shifting device 30 into the blind holes 12a on the back side of the ALC panel 12, and operate the ratchet wrench 52 to move the width shifting III ALC panel 12. Then, compress the seal backing to bring the IALc panel 12 into close contact with the ALC panel 12 on the fixed side. Furthermore, a new ALC panel 12 (the one that opens to the left in the drawing) is attached in the same manner, with the central ALC panel 12 in the drawing as the fixed side. As shown in FIGS. 2 and 3, the width adjusting device 30 includes a gear device (in the case of this embodiment, a combination of three bevel gears 56 and 58) housed in a housing or a support frame 40,
A pair of bearings, each rotatably fixed to the housing or support frame 40 and extending in opposite directions and having axial slots, are connected to the rod 42, the bearings each extending axially through the rod 42, and each having an axial slot therein. Bevel gear 56 of gear system
The bearings are connected to a pair of screw shafts 46 that are rotatable with respect to the rod 42, and are slidably engaged with the screw shafts 46, respectively. 42 (in the case of this embodiment, the support pin 62 of the floating support 60 protrudes), and the umbrella of the gear device for rotating the screw shaft 46. gear 58 to 8
It is comprised of a connected drive device (in the case of this embodiment, a ratchet wrench 52). In FIGS. 2 and 3, the housing or support rod 40 and the bearing rod 42 are shifted in position by 90 degrees from those in FIGS. 1 and 5. (In the case of the diagram, the bearing is connected to the housing or support rod 42.
Although it is fixed rotatably with respect to 0, it may simply be fixed. ) The driving device is provided with a clutch device (in the case of this embodiment, a ratchet 54, etc.), and the pair of screw shafts 46 are connected to each other.
You can rotate them at the same time or only on one side, and also reverse them. The housing or support frame 40 may be closed, or may be open on both sides, like a simple frame, or open on one side, like a bookshelf. However, in order to reduce weight, an open shape is better. As shown in the figure, the rods 42 of the pair of bearings extend symmetrically in opposite directions from a bevel gear 56 housed in a housing or support frame 40, and have a slotted hole cut out at the center in the axial direction. There is. The screw shaft 46 passes through the bearing 44 of the rod 42 into the housing or support frame 40 and is connected to a bevel gear 56 . A drive shaft 48 enters the housing or support frame 40 through a bearing 46 and includes a slidable thrust ring 50.
It is connected to the bevel gear 58 via. A ratchet wrench 52 is fitted into the opposite end of the drive shaft 48. The ratchet wrench 52 is provided with a ratchet 54 for switching the operation. Input from ratchet wrench 52 enters screw shaft 46 via drive shaft 48 and gearing 56,58 causing screw shaft 46 to rotate. As shown in FIG.
0a and a beam member 60b passing through the center of the annular member 60a. They are slidably engaged. Furthermore, the beam member 60b of the floating support fitting 60 has a bearing that fills the slot of the rod 42. In other words, the bearing is shaped to pass through the pierced central portion of the rod 42 or the gap between the annular member 60a and the beam member 60b. Therefore, for one bearing, insert the support pin 62 of the rod 42 into the hole in the ALC panel on the fixed side, and for the other bearing, insert the support pin 62 of the rod 42 into the hole of the ALC panel on the fixed side.
When the support pins 62 of No. 2 are inserted into the holes of the ALC panel for the width adjustment and the screw shaft 46 is rotated in a certain direction, the floating support metal fittings 60 approach each other as if dragging the ALC panel 12 for the width adjustment. . Further, the support pin 62 can be rotated along the circumference of the floating metal fitting 60, and if it is difficult to operate the handle of the ratchet 54 due to contact with an obstacle, it is also possible to change the direction of the support pin 62 and operate it. . An embodiment for such a case is shown in FIG. In FIG. 5, the support pin 62 of the width adjusting device 30 is inserted into the blind perforation Z2a on the back side of the ALC panel 12 in FIG. The support pin 62 of the Wa"Fr straightening device 30 is inserted. The operation of the width shifting device 30 is the same as that shown in FIG. 1. In the width shifting operation, the ratchet 5 of the ratchet wrench 52 is
4 can also be switched to move the ALC panel 12 in the opposite direction.

【Effect of the invention】
