Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method of constructing roof panels.

Conventional technology Conventionally, in order to reduce roof construction man-hours and transport costs, roof panels were divided at the ridge side, pivoted to each other, and transported to the site in a folded state using this pivot point as a fulcrum. It is considered that these roof panels are later opened and installed on a building frame, and the invention of such a roof panel is described in Japanese Utility Model Application Publication No. 51-156617. Furthermore, the specification states that by lifting the folded panel in this way with a crane, it can be opened under its own weight.

On the other hand, as a means to easily open the panel, Japanese Patent Laid-Open No. 54-71817 discloses that a rail groove is provided in the upper chord of the truss that has been previously constructed, and the metal fittings at the lower end of the panel are placed along this rail groove. A method of automatic installation on a truss by sliding is disclosed.

Problems to be Solved by the Invention In the conventional roof panel installation method described above, in which the panel is opened by its own weight when lifted, the panel opens close to the ground at the same time as it is lifted. There are drawbacks such as colliding with obstacles or danger to the operator.

On the other hand, although the latter method of using truss top chords as rails does not have these drawbacks, it cannot be used in structures without truss, that is, in which the frame is built into the panel itself, and in the end, a triangular rail body was developed to replace it. There is the inconvenience of having to install the

The present invention eliminates these conventional drawbacks and provides a method for constructing a roof panel that can be opened at any position from hoisting to installation on a frame.

Means for Solving the Problems In order to achieve the above object, in this invention, the roof dividing panel (1) (1) which is divided into two parts at the middle part is pivotally connected to each other at the divided ends, and the back side When folded, the pivot points (8) (8) of each divided panel (1) (1)
) at a position closer to the end opposite to the split end, and with the split end facing upward, and at the same time or after the lifting, apply a downward force to the split end. The device is characterized in that the non-divided end side is opened outward and installed on the frame (25).

Function: The roof panel (1B) produced in advance at the factory is transported to the site in a folded state, making it easy to transport. Embodiment Below, the structure of the present invention will be explained in more detail based on the illustrated embodiment. Figures 5 and below show the structure of the roof panel used in the present invention. In the figure,
(1) (1) is a roof dividing panel that is divided into two in the left and right direction with the vertical plane passing through the roof ridge as the border, and these roof dividing panels (1) are arranged at intervals in the direction of the roof ridge. The horizontal members (3) (3) passed between the roof ridge and eave side ends of the upper chord members (2) (2) and rain upper chord members (2) (2) made of a pair of channel steel ), the wooden purlins (4) (4) passed between the grooves of each top chord (2) (2), and the roof base plate (5) fixed on this purlin (4) with screws etc. )
Consisting of

Then, as shown in Figure 6 and below, each roof division panel (
1) At the end of (1) on the roof ridge side, each upper chord member (2)
Brackets (6) (6) protrude from the bottom surface of (2), and these brackets (6) (6)
It is pivotally attached to the end of the upper connecting fitting (7) via pivot pins (8) (8) so as to be freely rotatable in the vertical direction, thereby being foldably connected to the attic side. On the other hand, at a position near the end of each roof dividing panel (1) (1) on the eaves side, there is a pair of lower chord members (9) ( 9) is pivotally connected to the upper chord members (2) (2) by pins (ll) (u) so as to be able to freely rotate in the vertical direction, and both divided lower chord members (
9) The center end of (9) is connected to one lower connecting fitting (1
2) via a pin (13) so as to be rotatable. (14) is a bundle material, and this bundle material (1
4) The upper end is fixed to the lower surface of the upper connecting fitting (7) that connects the ridge side ends of the divided panels (1) (1), and the lower end thereof is formed into the lower connecting fitting (12). It is inserted into the vertical guide hole (15) so as to be slidable in the vertical direction. (16) is this bundle material (1
4) Connecting holes (
17), and this fixed bin (17) is installed after being installed at the site. That is, with this pin (17) removed, both roof dividing panels (1) (1
), the connecting fitting (12) slides over the bundle material (14) and each divided lower chord material (9) (9) is folded inward, whereby both divided panels (1) (1) It is designed to be stored in between. As shown in FIG. 4, four lower chord members (9) are used, two each in the direction of the roof ridge, and accordingly two bundle members (14) are used in the direction of the roof ridge.

(19) in Fig. 5 indicates each lower connecting fitting (12) (1
2) It is a connecting beam connected between.

Next, a method for installing the roof panel (one day) will be explained based on FIGS. 1 to 4. First, as shown in Figure 3,
The roof panel (18) is transported to the site by truck in a folded state as shown in the figure.

At the site, the four tips of the locking wires (21) are connected to the pivot joints on the divided ends of each divided panel (1), that is, the upper connecting fittings (7), and the pins (8) at both ends. (8), it is locked at a position closer to the end of the eaves on the opposite side to the split end, and lifted by the crane wire (23) suspended from the crane boom (22). Lift the roof panel (18) so that it is on the side. At this time, as shown in FIG. 2, the upper ends of the tension strings (24) are tied to the two upper connecting fittings (7), respectively, and the lower ends of the tension strings (24) are tied to the first As shown in the figure, if you tie it to the fixed member (25) (25) on the ground and lift it upward by operating the crane boom (22) in this state, the tension cord (24) (24) will be pulled. At the same time, this tension string (24) (2
4) acts as a force that pulls the divided end side of the divided panel (1) (1), that is, the upper connecting fitting (7) downward, so that this divided end side is pulled downward. As a result, both the divided panels (1) (1) open outward as shown in Fig. 2, and at the same time, the lower connecting fitting (12) slides downward along the bundle material (14). , since the split lower chord members (9) (9) are opened,
As it is, install it on the frame (26) and fix it as shown in Fig. 4. At this time, by inserting the fixing bin (16) or bolt into the lower end of the lower connecting fitting (12) and the bundle material (14), the zero-divided panel ( 1) Whether you want to open (1) at a low place near the ground or in the sky, you need to use a pull cord (24
) (24) can be changed by adjusting the length. Especially if you open it in the sky with no obstacles,
This type of work can be carried out even in relatively small spaces. Further, the tension string (24) may be connected to the lower end of the bundle material (14) and pulled, or furthermore, the tension string (24) may be tied to the lower connecting fitting (12) of the split bottom chord material (9) (9). The split panels (1) (1) may be opened by applying force directly to the lower chord members (9) (9). Furthermore, it may be pulled using a member other than the tension string (24), or the lower end of the tension string (24) may not be tied to a fixed member on the ground as described above, but may be pulled to a certain extent. It is also possible to manually pull it when it is lifted.

Effects of the Invention As described above, according to the present invention, after lifting with a crane or the like, an artificial force is applied to the split end side to open it, so by selecting the timing, the split end can be opened at any position. This has the effect of allowing work to be carried out efficiently even on narrow sites or in buildings without trusses.

In addition, such a downward force can be applied by a simple means of connecting strings, as shown in the examples.
The equipment itself requires only a small amount.
