Abstract

PURPOSE:To facilitate construction of a roof by connecting to a ground side roof panel a hoisting cable suspended from the ridge side of a roof, and connecting plural roof panels together and hoisting them in the direction of the ridge through the eaves by means of winding of the hoisting cable. CONSTITUTION:A winch 2 is installed in the attic 1 of a building A and a hoisting cable 3 is suspended from the eaves through the upper face of a roof truss 5 to the ground via a sheave 4 provided at the ridge, and a roller 7 for guiding roof panels 6 to be hoisted to the eaves is supported by a supporting member 8. The hoisting cable 3 has its end connected to one root panel 6 and is wound up and plural roof panels 6 are linked together in sequence by joint metal fittings 10 and are carried all at once from the eaves in the direction of the ridge and placed on the roof face. Thus the roof is readily constructed without using heavy machinery such as a crane.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof construction method, and more particularly to a construction method in which roof panels are carried onto the roof surface and set at a predetermined location. [Prior art] When constructing a roof with roof panels when constructing a house, N-root panels are made of a size that can be loaded onto a truck bed, taking into consideration the transportation aspect when transporting trunks from factories and other places to construction sites. It is common that it is made into a
Many roof panels will be used on one side.
Furthermore, even though each roof panel is manufactured within the dimensional constraints of the trunk, each individual roof panel is quite heavy, so normally a crane or the like is used to lift each panel onto the roof one by one. The roof panel is lifted and lowered to a predetermined location where it is to be pasted.

[Problems with conventional technology]

Therefore, heavy machinery such as a crane is always required for roof construction, so if a house is built in a geographic area where a crane cannot be brought in, there are restrictions on roof construction. Since the workpiece is set on the roof surface, it is difficult to install, and it requires work on the roof surface, which poses a safety problem.

[Problem to be solved by the invention]

In view of the above-mentioned problems, this invention allows N-root panels to be easily and quickly lifted onto a roof surface and set in a predetermined location without using heavy equipment such as a crane, and also allows work on the roof to be performed on the roof surface. This was done with the purpose of providing a roof construction method that does not require the following. [Technology that led to solving the problem] That is, the roof construction method of this invention is to tie a lifting cable hanging from the ridge side of the roof to the roof panel on the ground side, and by winding up the lifting cable, the roof panel is connected to the ridge through the eaves. This method is characterized in that a plurality of roof panels are connected in a daisy-like manner and carried up to the roof surface.

〔Example〕

Next, embodiments of the invention will be described.

FIG. 1 is a perspective view of an embodiment of the invention, and FIG. 2 is a side view of the embodiment.

In the roof construction method of the present invention, a winch-like hoist a2 is installed in the attic 1 of the building A, and the hoisting cable (wire, etc.) 3 of this hoist is connected to the roof assembly 5 through a sheave 4 provided at the ridge.
A support member 8 is used to guide rollers 7 for the roof panel 6 that is suspended from the eaves to the ground through the upper surface and is lifted from the eaves.
From this state, the tip of the lifting cable 3 is tied, for example, to the roof panel 6 on the cargo platform carried by the trunk 9, and the hoisting machine 2 winds up the lifting cable 3 and lifts the roof panel 6. By sequentially connecting the next roof panel 6 to the roof panel 6 that is being lifted up using the joint metal fittings 1o, a plurality of roof panels 6 are connected in a daisy chain shape, and these are carried all at once from the eaves toward the ridge. Raise it and place it on the roof. Note that the roof panels 6 may be connected to each other sequentially during lifting, or may be connected in advance.

Further, the joint fitting 1o for connection shall allow movement of the connected roof panels 6.6.

[Effect]

According to the roof construction method of this invention, a plurality of roof panels 6 to be attached to the roof surface from the eaves to the ridge can be lifted all at once in one lifting operation, and when the lifting is completed, the roof panels 6 can be lifted up at once. Roof panel 6 in the order
... are lined up from the ridge to the eaves, and each roof panel is automatically attached to its respective attachment point. In addition, the roof panels 6 can be lifted up by a winch operation in the attic 1 and the roof panel connection operation on the ground side, and the roof panels 6 after being carried can be moved up.
Fastening work can also be done from the attic ■.

〔effect〕

Since this invention is tiered as described above, it is possible to carry the roof panels onto the roof and set each roof panel on the roof easily and quickly without using heavy equipment such as a crane. There are no restrictions on roof construction, and the labor and time required for roof construction are greatly reduced, improving workability.Moreover, lifting and fixing roof panels does not require work on the roof surface. It has the advantage of being safe and can be performed without causing any damage.
