Description

[Detailed description of the invention] The present invention relates to an improvement of a connecting device between a girder and a purlin for a prefabricated metal storage shed, and the upper horizontal piece 2 of a girder 1 having a U-shaped cross section is inclined in the longitudinal direction of the girder 1. On the lower horizontal piece 3 of this girder 1, vertical pieces 5 projecting slightly upward from the lower horizontal piece 3 are erected at intervals approximately equal to the width of the purlin 4. It is inserted between the vertical pieces 5 of the piece 3, and the lower surface of the end of the purlin 4 is placed on the lower horizontal piece 3, and the upper corner of the end of the purlin 4 is pressed against the inclined upper horizontal piece 2 of the girder 1. This relates to the connecting device between the girder and the main building.

Conventionally, when connecting the girder 1 and the purlin 4 in a prefabricated metal shed, a mounting plate 6 is provided on the purlin 4 as shown in FIG. Since the bolt holes were installed in the vertical direction of the girder 1, it was difficult to connect them because bolt tightening work was necessary and the head of the bolt 8 was exposed on the outside of the girder 1. Since it is located in the piece 7, rainwater enters from the outside through the bolt hole.

Furthermore, since the mounting plate 6 is brought into contact with the vertical piece 7 of the girder 1, if there is an error in the length of the main building 4, it could not be mounted.

In the figure, 9 is a roof plate, 10 is a beam, and 11 is a column.

The present invention was devised in view of the above-mentioned conventional drawbacks, and its purpose is to fit the lower part of the end of the purlin between the upright pieces of the lower horizontal piece of the girder so that the lower surface of the end of the purlin can be fixed. By placing it on the lower horizontal piece and pressing the upper corner of the end of the purlin to the inclined upper horizontal piece, it is possible to connect the girder and the purlin only by rotating the purlin without using bolts as in the past. can be connected without using bolts, so there is no need to expose the bolt head to the outside of the girder as in the case of conventional methods.Also, since there are no bolt holes in the girder, there is no need to use open holes as in the case of conventional methods. To provide a connecting device for a girder and a purlin, which can be securely connected even if there is a dimensional error in the length of the purlin without fear of rainwater infiltrating through the purlin.

The present invention will be explained in detail below with reference to Examples.

In the figure, reference numeral 1 denotes a metal girder, which has a substantially U-shaped cross section, and the upper horizontal piece 2 of this girder 1 is inclined in the longitudinal direction of the girder 1.

That is, the vertical height of the vertical piece 7 of the girder 1 is such that one end of the girder 1 in the longitudinal direction is higher and the other end is lower.

A pair of vertical pieces 5 are erected on the lower horizontal piece 3 of the girder 1, and the width between the vertical pieces 5 is approximately equal to the width of the main building 4.

The vertical piece 5 is formed by cutting and raising the lower horizontal piece 3 of the girder 1, or is erected on the lower horizontal piece 3 by welding.

4 in the figure is a purlin, and in the embodiment shown in the figure, it is made of channel steel with a lip.

The purpose of attaching the main building 4 to the girder 1 is as follows.

That is, as shown in FIG. 3, first, with the main building 4 tilted, the end of the main building 4 is inserted into the girder 1 having a U-shaped cross section, and the lower corner of the end of the main building 4 is placed in the opposite vertical piece 5. Put it in between,
In this state, by rotating the purlin 4 in the direction of the arrow in FIG. 3, the end of the purlin 4 is fitted between the opposing vertical pieces 5, and the lower surface of the end of the purlin 4 is placed on the lower horizontal piece 3. , at the same time main building 4
The corner of the end of the girder 1 is pressed against the inclined upper horizontal piece 2 of the girder 1.
This is to connect the main building 4 to the main building 4.

In this case, since the upper horizontal piece 2 of the technique 1 is inclined in the longitudinal direction of the girder 1, the lower part of the end of the purlin 4 is inserted between the vertical pieces 5 and
can be rotated without any problem, and the corner of the end of the main building 4 can be pressed against the inclined upper stack 2 of the girder 1. Moreover, once the corner of the end of the main building 4 is pressed, the lower part of the end of the main building 4 becomes a vertical piece. By being fitted between the gaps 5 and 5, the main building 4 can be prevented from collapsing and can be reliably connected to the girder 1.

Moreover, since the purlin 4 can be connected to the girder 1 even if the end face of the purlin 4 does not come into contact with the vertical piece 7 of the girder 1, the connection can be ensured even if there is a dimensional error in the length of the purlin 4.

Further, unlike the conventional method, the work is easy because bolts are not required, and there is no fear that the bolts will be exposed on the outer surface of the girder 1, causing problems, or that rainwater will enter through the bolt holes.
