Description

[Detailed explanation of the invention] This invention allows large-sized chevron roofing materials to be easily attached to beams.
This invention relates to a large-sized mountain-shaped roof mounting device that allows for accurate mounting position.

Traditionally, long-span (approximately 15 m to approximately 50 m in length) and large (approximately 1 m to 1.5 m in height) chevron-shaped roofing materials have been produced in factories, transported to the site, and installed on the structures there. Each piece is lifted up one by one using a large crane, etc., and placed and fixed between the opposing beams on the top of the structure, and the adjacent large chevron roofing materials are aligned in parallel and tied together to form the roof. Ta.

The opposing beams at the top of the structure are generally supported by columns at multiple locations, and are long, and due to thermal distortion due to welding, stress distortion that occurs in the beams when building a frame structure, etc., the center of the beam Currently, there are many cases in which the road is not formed in a straight line, but in a meandering manner.

Even if the beam meanderes a little (depending on the length, it may actually be off center by about 1 cm to 10 cm), it is not considered a problem from the structural mechanics point of view.

However, the length of large-sized chevron roofing materials produced in factories is fixed to the same length for those used at the same site, and the length of the L-shaped metal fittings that are the attachment points of the strength bones at both longitudinal ends of the large-sized chevron roofing materials is fixed. The location is also accurate.

For this reason, even if you drill mounting holes in the L-shaped metal fittings and beams in advance and place the large chevron-shaped roofing material on the opposing beam and attempt to install it, the hole position may be incorrect due to the aforementioned meandering of the beam, etc. It was extremely troublesome to install it out of alignment, and in particular, the large chevron roofing material was so large that a large crane had to be used to move it even a little, which was extremely time-consuming.

In addition, if interior materials are installed on the inner surface of a large chevron roofing material, and if this material protrudes downward from the bottom of the ribs, it may be difficult to install it, or troublesome on-site installation work may be required. was there.

Therefore, in the present invention, a pedestal is fixed to the lower plate and the upper plate with a connecting rod, and a pedestal with a long hole bored in the lower plate is placed on the beam at the top of the structure at a predetermined interval. A bolt is inserted into the beam material through a long hole and fixed, and on the upper plate of the adjacent pedestal, a steel frame with a cross section approximately the same as that of the large chevron roofing material is fixed to the lower surface of the longitudinal end of the large chevron roofing material. By placing and fixing the L-shaped metal fittings attached to both ends of the beam, the lower plate of the pedestal can be fixed in an accurate position via the elongated hole on the new center line set on the sometimes meandering beam material. Large chevron-shaped roofing materials can be easily installed on the pedestal, and even if the interior material of the large-sized chevron-shaped roofing material may protrude a little below the lower side of the frame, the pedestal will prevent any hindrance. It can be easily installed and eliminates the above-mentioned drawbacks.

Its structure will be explained with reference to the drawings.

Reference numeral 1 denotes a beam member, which is provided on the upper part of the structure 2 so as to face each other in parallel.

The neutral axis (center line) of the beam 1 itself when viewed in plan is often meandering, so after the beam 1 is installed on the structure 2, the straight center line g of the beam 1 is It is depicted.

Reference numeral 3 denotes a pedestal, which is constructed by fixing a quadrilateral lower plate 4 and an upper plate 5 with a connecting rod 6.

A plurality of long holes 7 (four in the drawing) are formed near the periphery of the lower plate 4, and a plurality of attachment holes 8 (four in the drawing) are formed in the upper plate 5 near the periphery.

This pedestal 3 is placed on the beam 1 at a predetermined interval (width of the large-sized chevron roofing material 10 described later), and its lower plate 4
Insert the bolt 9 into the beam 1 through the long hole 7 by appropriately shifting the long hole 7 in the direction orthogonal to the center line g so that the fixed point of is located on the center line g on the beam 1. It is fixed by tightening the nut.

The mounting holes for the bolts 9 in the beam material 1 are drilled before the center line g is provided.

Reference numeral 10 is a large chevron roofing material with a long span, in which a sloped edge facing outward and upward is formed from both bottoms of the large cross-section chevron portion, and an edge sloped upwardly and inwardly from the upper end of the sloped edge is integrally formed. has been done.

Reference numeral 11 denotes reinforcement bones, which have approximately the same shape as the cross section of the large-sized chevron roofing material 10. A plurality of reinforcement bones 11 are fixed to the lower surface of the large-sized chevron-shaped roofing material 10 at predetermined intervals in the longitudinal direction. It is also provided at both ends.

L-shaped metal fittings 12.12 are symmetrically fixed to both ends of this force bone 11.

The bottom of this L-shaped fitting 12 is attached to the upper plate 5 of the pedestal 3.
A through-hole is bored corresponding to the mounting hole 8 of.

The L-shaped metal fittings 12.12 fixed to the longitudinal ends of the large-sized chevron-shaped roofing material 10 are placed on the upper plates 5, 5 of the adjacent pedestals 3, 3, and the mounting holes 8 and the through hole of the L-shaped metal fitting 12 are aligned and fixed with bolts and nuts 13.

On the pedestal 3, both of the opposing L-shaped fittings 12.12 of the adjacent large-sized chevron-shaped roofing material 10.10 are placed (see Figure 2), and the opposing L-shaped fittings 12.12 are also bolted to each other. They are tied together by Natsuto.

14 is a heat insulating material, 15 is an interior board, and 16 is a parting member that supports the lower end of the interior board 15, and is fixed to the lower part of the L-shaped metal fitting 12 of the large-sized chevron roofing material 10.

Next, the effects will be explained.

In the present invention, a pedestal 3 in which a lower plate 4 having a long hole 7 and an upper plate 5 are fixed with a connecting rod 6 is placed on the beam 1 on the upper part of the structure 2 at a predetermined interval. Since it is fixed by the bolt 9 and nut from the long hole 7, even if the beam 1 is constructed in a meandering manner, the long hole 7 of the lower plate 4 can be shifted appropriately on the beam 1, and the center of the beam 1 can be adjusted. line g
It can be fixed in the exact position on the top.

On the upper plates 5, 5 of the adjacent pedestals 3, 3 provided at such accurate positions, L-shaped metal fittings 12.
12 has been placed and fixed, the large chevron roofing material 10, which is factory-produced to a certain size, is suspended by a large crane, etc., and placed once on the pedestal 3.3, and the pedestal 3.
The bolt mounting hole positions of the shaped metal fittings 12 match accurately, and unlike conventional methods, when the mounting positions of the large chevron roofing material 10 and the beam material 1 do not match, it is necessary to drill the mounting holes at different locations or Each time,
The trouble of moving the large chevron-shaped roofing material 10 using a large crane is completely eliminated, and the present invention allows the large-sized chevron-shaped roofing material 10 to be easily and quickly transferred to the beam material 1 via the pedestal 3.
Can be installed on.

In addition, the pedestal 3 is provided between the beam material 1 and the large-sized chevron-shaped roofing material 10, so that the large-sized chevron-shaped roofing material 10 is slightly raised, so that the space for its installation is widened, and the upper plate 5 and the L-shaped metal fitting 12 This makes installation extremely easy.

Furthermore, even if the heat insulating material 14 and the interior panel 15 are installed inside the large chevron-shaped roofing material 10, and the parting material 16 that supports them is provided so as to be lower than the bottom of the L-shaped fitting 12, the entire body will be lifted up by the pedestal 3. It does not cause any trouble.

In this way, by interposing the pedestal 3 with an extremely simple configuration, accurate installation, simple and quick installation is possible, and as a result, the construction of a large chevron roof can be speeded up, and the construction cost can be made relatively low. It has the following effects:
