Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for constructing a folded plate roof and a hanging device used therein.

(Conventional technology) In the method of constructing a roof by suspending a pre-assembled roof purlin steel frame and roofing material (large assembly method), conventional lifting sling wires are hung directly on both ends of the roof purlin steel frame and hoisted. After setting in place, the lifting sling wire was removed, and the openings (unused) left on both ends of the steel frame without roof plates attached were covered with roof plates in order to hang the sling wires. ing.

(Problem to be Solved by the Invention) Conventionally, in order to directly hang wires on a steel frame, it was necessary to provide wide openings on both sides of the roofing material, and these openings remained open until the roofing work was completed. The remaining parts required handrails or safety equipment around the openings, which ultimately had to be removed and further work to cover the openings. For this reason, roof work was often done after the roof had been set, resulting in poor work efficiency. In addition, removing the hanging wire requires leaning over the roof material into the opening in an unstable position, or climbing on top of the roof steel frame inside the opening, making the work extremely difficult. It was dangerous.

The purpose of the present invention is to improve work efficiency in roof construction, increase work safety, and enable stable hanging of assembled roofs.

(Means for Solving the Problems) In the roof construction method of the present invention, a roof material 2 is placed and fixed on a roof steel frame 1 on which a hanging support 4 is erected, protruding from the upper surface of an assembled roof A. The hanging body 5 is attached to the attachment part 4a1 of the hanging support 4, and the hanging wire 7 is hooked to this hanging body to lift the assembled roof and install it in a predetermined position.After assembling the steel frame, the hanging body 5 can be attached as necessary. It must be removed.

The suspension device used in constructing the folded plate roof of the present invention has a suspension support 4 erected on the roof steel frame 1, and a mounting portion 4a1 provided at the top of the suspension support is located at a position protruding from the roof material 2. A hanging body 5 is removably attached to the mounting portion, and this hanging body holds the roof material between the hanging support body and a hanging wire 7 can be hooked to the hanging body. .

(Function) The hanging wire 7 suspends the assembled roof A using the attachment portion 4a1 of the hanging support body protruding above the roofing material 2, and no opening is required in the roofing material. The hanging support has the function of supporting the roof material 2 and the function of suspending it together with the hanging body 5.

(Example) Examples of the present invention will be described below with reference to the drawings.

First, a suspension device used in the roof construction method according to the present invention will be explained, and then the construction method will be explained.

1 to 3, a roof steel frame 1 made of H-shaped steel has a frame 3 made of a steel plate having a shape matching the waveform of the folded plate roofing material 2 attached in the longitudinal direction on an upper flange 1a. Bolts 3a are erected at the tops of the respective peaks of the frame 3, and the roofing material is fixed to the bolts with nuts 3b. Hanging supports 4 are provided at two locations on the upper flange 1a in line with the peaks of the frame 3. The suspension support 4 includes a bolt 4a and a receiving plate 4.
It consists of b. The bolt 4a is erected on the flange 1a, and the upper part of the bolt is a mounting portion 4a1 having a male thread formed on the outer periphery. The attachment portion four a1 is located higher than the tops of the peaks of adjacent frames 3, and can protrude above the peaks of the roofing material 2. The receiving plate 4b is for reinforcing both sides of the bolt 4a, and is fixed to the bolt and the flange 1a by welding. The receiving plate is formed in the same shape as the peak of the frame, and receives the roof material 2 at its upper end. There is a U on the bolt mounting part 4a1.
A letter-shaped hanging body 5 is attached through a mounting hole 5a. Then, it is attached to the attachment portion 4a1, and a nut 6, which is a fixing means, is tightened to fix the hanging body 5 to the receiving body 4b side. A hanging rod 5b is horizontally extended over the hanging body 5, and is fixed with nuts 5c at both ends. A hanging wire 7 is hooked onto this hanging rod 5b.

Next, we will explain how to construct the roof.

Roofing steel frames 1 are arranged, a roofing material 2 is placed on a frame 3 from above, and the peaks of the roofing material are aligned with the peaks of the frame and a hanging support 4. Then, in the example shown in the third figure, the mounting portions 4a1 of the bolts 4a of the hanging support 4 protrude from four locations of the roof material by a predetermined length, so the hanging body 5 is attached to these projecting ends and fixed by tightening with nuts 6. do. Note that the roof material 2 is also fixed on the frame 2 with bolts 3a and nuts 3b. As a result, an assembled roof A is formed as shown in FIG. After this, the hanging wires 7 are hooked to the hanging rods 5b of each hanging body 5, and the assembled roof is lifted up and set in a predetermined position. After assembling the steel frame, the nuts 6 are removed from the mounting portions 4a1. The hanging body is removed from the mounting part 4a1, a waterproof material such as packing is applied to the mounting part, and the nut 6 is tightened again to finish the roof construction.

Although the nut 6 is used as the fixing means for the hanging body 5 in the above example, it may be configured such that, for example, a female screw is provided on the inner periphery of the attachment hole 5a and this screw is connected to the screw of the attachment portion 4a1.

(Effects of the Invention) As explained above, according to the present invention, there is no need to leave openings in the roofing material for hanging wires, so conventional safety equipment such as handrails and nets is no longer required, and safety equipment installation is easy. This eliminates the need for removal work at all, contributing to the efficiency of roof construction, and also makes the work extremely safe as the hanging wire can be removed in a stable working position on the roofing material. In addition, the hanging support can be used as a means for supporting the roofing material, it can be hung stably, and the hanging body can be used for other purposes, which is economically advantageous.
