Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a chisel-jointed roof structure with chisel-folded roof plates used for long-span roof structures such as factories, warehouses, and gymnasiums. This relates to improvements in the tight frame used.

[Conventional technology]

As shown in FIGS. 4 to 6, in the conventional cross-jointed frame of this type, a chevron-shaped support frame 2 is sequentially connected to a beam 1 serving as a supported part and fixed by welding, and both sides of this chevron-shaped support frame 2 are The joints on both sides of the cross-folded roof board 3 mounted on the oblique side are connected in a cross-seamed manner. As shown in FIG. 5, this folded roof board 3 has an inward folded joint 4 and an outward folded joint 5 on both sides of the almost gutter-shaped roof. The folded joint part 4 of the roof board is inserted, and the bent upper edge of the reinforcing hanging plate 6 is sandwiched between the two, and the hanging part of this reinforcing hanging plate is formed on the top of the chevron-shaped support frame 2. The bolt 8 and the nut 9 are screwed onto the stepped vertical surface 7.

[The problem that the idea attempts to solve]

The conventional roof plate joint frame having the above configuration is
It is suitable for long-span roof structures such as warehouses because joint joints can be quickly connected using a self-propelled electric tightening machine, and the fastening bolts do not protrude from the roof surface, which is advantageous for corrosion resistance. It is used.

However, since the chevron support frame 2 has a shape as shown in FIG. 6, if you want to change the direction of the cross-joints of the folded roof shingles 3, you can reverse the arrangement direction of the chevron support frame 2. The problem was that it had to be welded, making it difficult to install and work. Furthermore, the chevron-shaped support frame 2 with the structure shown in FIG. There was a problem that was said to be damaging.

The present invention was devised in view of the above points, and an object of the present invention is to provide a tight frame that can significantly improve construction efficiency, workability, and strength.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a horizontal concave portion having a substantially zigzag shape in plan, which is recessed in the center of the top portion of the main body exhibiting a substantially mountain shape and extending in the width direction of the main body; A pair of L's remaining on the top and exhibiting horizontal and diagonal symmetry on the plane.
It is characterized by comprising a letter-shaped protuberance, and bolt insertion holes that are surrounded by each of the L-shaped protuberances and are bored diagonally opposite to the horizontal recesses.

[Effect]

According to the present invention, since the pair of L-shaped protuberances exhibiting diagonal left-right symmetry in plane are formed on the top of the substantially mountain-shaped main body by the horizontal concave part having a planar zigzag shape extending in the width direction of the main body, It is possible to significantly increase the support strength of the chevron-shaped support frame body that supports the folded roof panels, and even if the direction of the split joints of the folded roof panels changes, the hanging edges of the reinforcing hanger plates can be adjusted accordingly to each of the above L. This can be done immediately by abutting either one of the end elevations along the side edge of the top of the letter-shaped raised portion, and construction efficiency, workability, and strength can be greatly improved.

〔Example〕

Hereinafter, the present invention will be described in detail based on an embodiment shown in FIGS. 1 to 3. In the figure, 10 is a body of a tight frame according to the present invention,
As shown in the figure, there is a top part 11, a hypotenuse part 12 which is bent downward from both sides of the top part 11, and a horizontal part which is bent horizontally from the lower end of the hypotenuse part 12. The bottom portion 13 is located at the bottom portion 13, and has a substantially mountain shape.

Reference numeral 14 denotes a horizontal concave portion recessed in the center of the top portion 11 and extending in the width direction of the top portion 11. As shown in FIG. It forms a recess.

Reference numeral 15 denotes a pair of L-shaped protuberances left on the top portion 11 by the recessed formation of the horizontal concave portion 14;
As shown in FIGS. 2 and 3, these raised portions 15 are diagonally symmetrical in a plane, and the horizontal recessed portion 14 is provided at the end of the raised portion 15 along the side edge of the top portion 11. The vertical surface 16 is vertically bent (see FIG. 3).

Reference numeral 17 indicates a pair of obliquely opposing bolt insertion holes formed in the horizontal recess 14 while being surrounded by the L-shaped protuberance 15, and 18 indicates a pair of bolt insertion holes in the horizontal recess 14 provided with the bolt insertion hole 17. This reinforcing hanging plate 18 is arranged in either the left or right direction, and as shown in FIG. 1, the reinforcing hanging plate 18 has a bent top edge 18a,
A vertical portion 18b is formed vertically downward from this bent top edge 18a, and a horizontal lower portion 18c is formed by bending and extending horizontally from the lower end of this vertical portion 18b.
A bolt hole (not shown) that overlaps with the bolt insertion hole 17 is bored in this horizontal lower portion 18c. This reinforcing hanging board 18 is
As shown in FIG. 1, the lower edge of the vertical portion 18b is brought into contact with either one of the end elevations 16 of the pair of L-shaped raised portions 15, and the bolt insertion hole 17 and the bolt hole of the horizontal lower portion 18c are brought into contact with each other. bolt 19 is washer 2
0 and nuts 21, it is firmly fixed to the horizontal concave portion 14 in either the left or right direction and functions to support the folded roof sheet 3.

With the above configuration, first, the bottom parts 13, 13 are welded onto the beam 1, and then the bent top edge 18a of the reinforcing hanger board 18 is attached to the inwardly folded joint part 4 of the folded roof boards 3, 3.
At the same time, the reinforcing hanger plate 18 is placed in contact with one of the end elevations 16 of the L-shaped raised portion 15 rising from the horizontal recessed portion 14, and the bolt hole is opened. superimposed on the bolt insertion hole 17,
Next, the bolt 19 is inserted from below the bolt insertion hole 17.
The folded roof panels 3, 3 can be firmly fixed to the tight frame by inserting the washer 20 through the threaded rod portion and screwing the nut 21 (see FIG. 1).

In this assembled and fixed state, the horizontal upper parts of the folded roof panels 3, 3 are superimposed and supported by the raised portions 15 of the tight frame, compared to the conventional configuration shown in FIG. However, it is possible to significantly increase the strength.

In addition, even when external forces such as strong winds are applied,
The tight frame is strongly resistant due to the cooperative support action of the central horizontal recessed part 14 and the protruding part 15 which is bent and connected at different levels through the vertical surface 16 rising from it, so that the tight frame and the vertically folded It can be expected that damage to the roof panels 3 can be reliably avoided.

Furthermore, the direction in which the folded top edge 18a is bent can be changed by arranging the reinforcing hanger plate 18 in either direction in the horizontal recessed part 14 depending on the mounting state of the folded roof panel 3. The mounting state of the folded roof panels 3 is not limited, and construction and workability can be greatly improved.

Furthermore, the bolt 1 is inserted into the horizontal recessed part 14 that bends and passes through the width direction of the top part 11 that is recessed.
Since the bolt insertion holes 17 into which the bolts 9 are inserted are bored, with the folded roof panels 3, 3 fitted into the bent top edges 18a, the screws of the bolts 19 inserted from below are inserted into the top 11. The nut 21 inserted from the width direction can be easily screwed on, making it possible to significantly improve work efficiency.

It can be applied immediately by contacting one of the end elevations along the side edge of the top of the
Workability and strength can be significantly improved.
