Abstract

【Task】
When a reinforcing arch is installed in a pipe house, the lower mounting can be strongly fixed with a simpler structure and can be slid for adjustment, and the lower mounting can be adjusted with a larger distance from the straight pipe.
[Solution]
In the present invention, the lower mounting bracket 10 is formed by bending a single flat plate, and the lower mounting of the reinforcing arch 6 is crushed so that the outer surface of the deformed portion 8 and the lower flat surface portion 9 becomes an integrated flat surface. In this case, the reinforcing arch is a round pipe, which can be rotated by a cylindrical holding portion 1, a rotation-preventing push bolt 2 and a support arm 3, and connected and fixed by a straight pipe holding bracket 4 and a support bolt 5.
It became possible to adjust the distance to the main building straight pipe 7 to be larger.

Description

  The present invention relates to a mounting bracket that reinforces a roof portion of an existing pipe house using a reinforcing material.

The cross section of the roof of the existing pipe house is as shown in Fig. 6. To reinforce this roof, attach the reinforcing arch under the roof arch in parallel with the band as shown in Fig. 7, but in fact the shape of the roof arch is very various, and the arch is measured for each property I tried to manufacture a reinforcing arch according to the measured value, but with the extent that the joint was made as shown in Fig. 8 and the bolt hole was a long hole, the difference between each property was too large and it did not fit easily. A lot of manufacturing costs were required, and the installation work was not easy. Next, the structure of the reinforcing arch shown in FIG. 9 was obtained, and the structure shown in FIG. 10 and FIG. 11 was obtained. The manufacturing cost was high because it was adjusted and manufactured. Also, since FIG. 10 has a complicated structure, the cost is high.

  When manufacturing reinforced arches, the existing roof arches are different for each property, and it is a problem that the manufacturing cost increases because it is manufactured by adjusting the bending of the reinforced arch measured for each property. .

  For various changes in the distance from the roof arch of the existing pipe house, the reinforcing arch is a round pipe and the support bracket holding part 1 is cylindrical, and is prevented from rotating on the circumference of the middle part. A support arm 3 having a fulcrum bolt hole at the tip is provided on the same circumference as the push bolt 2, and then a straight pipe holding bracket 4 is attached to the main pipe straight pipe that intersects the reinforcement arch at a right angle. A support bracket with a structure in which the fulcrum bolt hole at the tip of the holding bracket 4 and the fulcrum bolt hole at the tip of the support arm 3 are connected by the fulcrum bolt 5, but the holding part 1 is against the reinforcing arch 6 which is a round pipe. Since the fulcrum position of the tip of the support arm 3 can be greatly changed by rotating the support arm 3, even if the distance between the purlin straight pipe 7 and the reinforcing arch 6 is greatly changed, the holder 1 is rotated to rotate the purlin straight pipe 7 Can now be supported.

If the support arm 3 has a flat plate at the tip and can be fastened and fixed by being connected to the straight tube holding metal fitting 4 with a fulcrum bolt 5, the base portion of the support arm 3 may be a pipe, an angle, or a belt-shaped flat plate.

  When the holding portion 1 is rotated, the tip of the support arm 3 can be moved greatly, and the purlin straight pipe can be supported even if the distance between the purlin straight pipe 7 and the reinforcing arch 6 changes greatly.

When the deformed portion 8 and the outer surface of the lower flat surface are crushed so as to be an integrated flat surface, there is no protrusion to the outside of the deformed portion 8, so that the reinforcing arch mounting portion 13 can be moved greatly and the existing pipe house is reinforced It became easier to match the arch.

The reinforcement arch mounting portion 13 and the reinforcement arch lower plane 9 are joined to each other and can be tightened more strongly with the tightening bolts 17.

The conventional lower mounting bracket shown in FIG. 10 is a product in which three parts are integrally formed by welding. Since the lower mounting bracket 10 of the present invention is one product and there is no welding work, the manufacturing process is greatly reduced.

At the joint between the lower mounting bracket and the reinforcing arch, the lower part and the tip of the reinforcing arch were crushed so that the outer planes of the lower flat part 9 and the deformed part 8 with respect to the arch shape become an integrated flat surface.

  In order to make the structure of the lower mounting bracket a simple structure, the lower mounting bracket 10 consisting of the constituent elements of the C steel mounting portion 11, the seating position adjusting portion 12, and the reinforcing arch mounting portion 13 is replaced with a single flat plate as a predetermined element. It was made possible only by bending as shown in FIG.

In FIG. 1 to FIG. 5, the lower mounting bracket 10 is attached to the pipe house girder 16 together with the backing plate 15, the required number of holding portions 1 are inserted into the reinforcing arch 6, and the left and right reinforcing arches 6 are connected to the upper joint 18. While being combined and lifted, the lower flat portion 9 of the reinforcing arch and the reinforcing arch mounting portion 13 are joined, and the overall distance is adjusted using the tightening bolt 17 and the elongated hole portion 14 of the reinforcing arch mounting portion 13. Tighten the fastening bolt 17. Next, as shown in FIG. 2, the straight pipe holding metal fitting 4 is attached to each main purlin straight pipe 7, and the interval between the main purlin straight pipe 7 and the reinforcing arch 6 is adjusted by rotating the support arm 3. Then, the joining is completed by tightening the rotation-preventing push bolt 2.

  Embodiments will be described below with reference to the accompanying drawings.

  FIG. 1 shows a state in which the entire reinforcing arch is assembled. A lower mounting bracket 10 is attached to a pipe house girder 16, a lower flat portion 9 of the reinforcing arch 6 is attached, and an upper portion of the reinforcing arch 6 is a holding portion 1 shown in FIG. The distance from the main pipe straight pipe 7 is adjusted and fixed by a reinforcing arch support made up of a rotation stopping push bolt 2, a support arm 3, a straight pipe holding bracket 4, and a fulcrum bolt 5.
