Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a roof panel installation method for lifting and installing a roof panel on a roof at a construction site of a building such as a prefabricated house.

[Background technology]

Conventionally, when installing a roof panel on the roof of a prefabricated house or the like, the roof panel was hoisted horizontally using a hanging cord. As a result, it was difficult to install it on a sloped roof.

[Purpose of the invention]

An object of the present invention is to provide a roof panel installation method that allows the roof panel to be smoothly installed on the roof and has good workability.

[Disclosure of the invention]

The roof panel installation method of the present invention includes the steps of: preparing a hanging jig having a plurality of hanging strings that are connected to each other at the upper end and have different lengths depending on the roof slope; and installing a pair of horizontal flanges protruding from the upper and lower parts. A fixed part having a substantially U-shaped cross section, a screw rod screwed into the upper horizontal flange, and a movable plate rotatably attached to the tip of the screw rod and capable of moving up and down between the pair of horizontal flanges. a step of preparing a plurality of string fastening means, each string fastening means being attached to both sides of the roof panel with the side portions of the roof panel being fitted between the movable plate and the lower horizontal flange; arranging them apart in the direction of inclination of the roof panel and fixing each string fastening means to the roof panel by tightening the screw rod; a step of hooking each of the hanging cords and lifting the roof panel to an inclined position corresponding to the roof slope using the hanging jig; a step of lowering and installing the lifted roof panel onto the roof frame; The method includes the steps of removing each of the hanging strings hooked to each of the string fastening means, loosening the screw rod, and removing each of the string fastening means from the roof panel.

According to the configuration of the present invention, since the roof panel is lifted up in an inclined posture that matches the roof slope, the lifted roof panel can be smoothly installed on the roof, resulting in good workability.

Embodiment FIGS. 1 to 4 show an embodiment of the present invention.
This will be explained based on the diagram. This roof panel installation method includes the steps of preparing a hanging jig 1 having a plurality of hanging strings 2 and 3 that are connected to each other at the upper end and have different lengths depending on the roof slope, and a pair of horizontal flanges 5d and 5e. A fixed part 5a protruding from the upper and lower parts and having a substantially U-shaped cross section, a screw rod 5c screwed into the upper horizontal flange 5d, and a pair of horizontal flanges 5d and 5e rotatably attached to the tip of the screw rod 5c. A step of preparing a plurality of string fastening means 5 each consisting of a movable plate 5b that can be moved up and down between the two, and inserting each string fastening means 5 into the side part of the roof panel 4 between the movable plate 5b and the lower horizontal flange 5e. In this state, attach the roof panel 4 to both sides of the roof panel 4.
a step of fixing each string fastening means 5 to the roof panel 4 by tightening the threaded rod 5; A step of hooking the hanging strings 2 and 3 and lifting the roof panel 4 to an inclined position matching the roof slope using the hanging jig 1; and a step of lowering and installing the lifted roof panel 4 onto the framework of the roof 6. This method includes the steps of removing each of the hanging strings 2 and 3 hooked to each of the string fastening means 5, loosening the screw rod 5c, and removing each of the string fastening means 5 from the roof panel 4.

In FIG. 1, a hanging jig 1 includes hanging strings 2 and 3.
and a hanging rod 7. Hanging string 2 is hanging string 3
shorter in length than These hanging strings 2 and 3 are
Each has hook portions 2a and 3a at both ends. The hanging rod 7 is made of iron or the like, and has hook parts 7a on both ends of the lower surface for hooking the hook parts 2a and 3a, and has hook parts 7b on both ends of the upper surface for hooking the wire of a crane or the like. have.

The roof panel 4 is constructed by pasting a plurality of flat plates serving as roofing boards on a blank frame 8. As shown in FIG. 3, the string fastening means 5 is a jig consisting of a fixed part 5a, a movable part 5b, and a bolt 5c. The fixing part 5a is made of a U-shaped cross-sectional member with a pair of horizontal flanges 5d and 5e projecting from the upper and lower parts. The movable part 5b is made of a flat plate. The bolt 5c is screwed through the upper surface of the fixed part 5a, and the movable part 5b is rotatably attached to the tip of the bolt 5c. The string fastening means 5 is
The movable part 5b is moved by screwing in the bolt 5c, and the wooden frame 8 on both sides of the roof panel 4 is held between the lower horizontal flange 5e and the movable part 5b from above and below. The string fastening means 5 are attached in pairs at corresponding positions on both side surfaces of the roof panel 4 and spaced apart in the direction of inclination of the roof panel 4.

The hanging strings 2 and 3 each pass through the lower surface of the roof panel 4, with the shorter hanging string 2 being placed below the string fastening means 5 located above the slope, and the longer hanging string 3 being placed below the string fastening means 5 located below the slope. It is hooked below 5.

When removing each of the hanging strings 2 and 3 hooked on each string fastening means 5, use the hook part 2 at one end of the hanging strings 2 and 3.
a, 3a are removed from the hook portion 7a of the hanging rod 7, and the hook portions 2a, 3a are passed under the roof panel 4, thereby removing each of the hanging strings 2, 3 from the string fixing means 5. When removing the string fastening means 5 from the roof panel 4, loosen the threaded rods 5c to the extent that the wooden frame 8 can be loosely fitted between the horizontal flange 5e at the bottom of the movable plate 5b, and then remove the string fastening means 5 from the wooden frame 8. Pull it out.

According to this embodiment, since the roof panel 4 is lifted up in an inclined position matching the roof slope, the lifted roof panel 4 can be smoothly installed on the roof, and is easy to install.

Moreover, after the roof panel 4 is lowered and installed on the frame of the roof 6, the string fastening means 5 can be easily removed from the roof panel 4 by loosening the screw rod 5c. Therefore, even when constructing a plurality of roof panels in succession, this string fastening means 5
Since it can be used again, it is not necessary to prepare a large number of string fastening means 5 at the construction site, which is convenient.

Since the central portions of the hanging cords 2 and 3 are placed along the lower surface of the roof panel 4, the load on the roof panel 4 is received by the entire central portion of the hanging cords 2 and 3 and is not concentrated at one point. Therefore, generation of distortion in the roof panel 4 can be prevented.

The string fastening means 5 may be formed integrally with the roof panel 4 by providing grooves or protrusions in the wooden frame 8 on both sides of the roof panel 4.

The lengths of the hanging cords 2 and 3 may be adjusted.

The center portions of the hanging cords 2 and 3 may be formed into a wide band. In this way, the load on the roof panel 4 can be further dispersed, and distortion is even less likely to occur.

The number of hanging cords 2 and 3 may be three or more.

The hanging strings 2 and 3 may be hooked onto the string fastening means 5 without passing through the underside of the roof panel 4.

〔Effect of the invention〕

According to the panel installation method of the present invention, since the roof panel is lifted up in an inclined position that matches the roof slope, the lifted roof panel can be smoothly installed on the roof, resulting in good workability.

Moreover, after the roof panel is lowered onto the roof frame and installed, the string fastening means can be easily removed from the roof panel by loosening the screw rod. Therefore, even when a plurality of roof panels are installed in succession, this string fastening means can be used again, which is convenient because it becomes unnecessary to prepare a large number of string fastening means at the construction site.
