Description

[Detailed description of the invention] [Industrial application field] The present invention consists of a steel base frame that can be attached to the structural steel frame of a building from inside the building, and a steel base frame that is fixed to the upper surface of the base frame. This invention relates to a hanging jig for attaching a roof panel, which is used when attaching a roof panel consisting of a wide metal roof surface material to a structural steel frame.

[Conventional technology]

Conventionally, when tiering metal roofing sheets, for example, the metal roofing sheets are formed on the upper surface of the roof base consisting of the purlin, rafters, roofing boards, etc., at the rear end (the end on the water side) of the metal roofing sheet. After that, the upper metal roof sheet is attached to the lower metal roof sheet that has been previously roofed with the engaging portion formed at its front end. With the metal roof plates fitted into the stoppers, attach them to the roof base using similar hangers, and then repeat the same process one after another from the bottom to the top. It was attached to the top of the base.

For this reason, work efficiency is very poor, and if the slope of the roof is gentle, it is difficult to climb on top of the roof base.
We can install metal roof panels, but
In the case of a steep slope, the installation work of metal roofing sheets to the roof substrate must be done from roof scaffolding assembled along the roof substrate, which, together with the fact that the metal roofing sheets must be installed one by one, reduces work efficiency. The work was very difficult and extremely dangerous.

[Problem that the invention attempts to solve]

These conventional drawbacks can be overcome by constructing a roof panel by integrating a metal roofing material made of a plurality of tiered metal roofing sheets and a steel base frame that functions as a roof base in advance on the ground. Sweeping can be accomplished by configuring the roof panels to be lifted and attached to the building's structural steel from within the building.

However, in order to enable this type of panel construction method, it is necessary to suspend the roof panels (at least while temporarily securing them with bolts and nuts) until the structural steel frame is installed, and after installation, the roof panels must be Some kind of lifting jig is required that allows it to be separated from the

As for this hanging jig, first, for example, a through hole is provided in the surface of the roof panel, and a nut member larger than the through hole is screwed onto the lower end side of the hanging bolt inserted into the through hole from above. This is possible, but in this case, the through hole would need to be repaired after the roof panel is installed, which would result in a design defect, and the roof panel would have to be attached to the structural steel frame from inside the building. Despite this, repair work must be carried out on the roof, which can be quite dangerous on steeply pitched roofs.

Therefore, the present invention is a new and useful suspension that can lift roof panels without damaging the metal roof surface material, eliminates the need for repair work on the roof, and allows roof panels to be installed safely and easily. The purpose is to provide a jig.

[Means for solving problems]

In order to achieve the above purpose, the technical measures taken by the present invention are as follows. That is, the hanging jig for attaching roof panels according to the present invention includes a steel base frame that can be attached to the structural steel frame of a building from inside the building, and a metal base frame that is wider in width than the steel base frame that is fixed to the upper surface of the base frame. A hanging jig used when attaching a roof panel made of a metal roofing material to a structural steel frame, the main body being detachable from the side surface of the steel base frame, and the metal roofing material attached to the tip of the main body. A first member consisting of a protrusion provided to protrude outward from the side edges of the roof panel, and a hanging part on the upper end side of the plate material which is thinner than the width of the vertical joint between the left and right adjacent roof panels, A second member is provided on the lower end side, each of which has a notch or a through hole that can be engaged with and disengaged from the protrusion.

[Effect]

According to the above configuration, the first member is attached to the side surface of the steel base frame of the roof panel, the notch or through hole of the second member is engaged with the protrusion of the first member,
A chain or the like is connected to the hanging portion of the second member, and the roof panel can be lifted up by a crane or the like.

Then, after attaching the roof panels to the structural steel,
By working from below the roof panel, remove the notch or through hole from the protrusion, pull out the second member upward from the vertical joint of the adjacent roof panel, and use it for the next roof panel lifting operation. One part will be removed from the steel base frame by working from below the roof panel and used for the next roof panel.
